• TFS Hosting: discountasp.net TFS

  - by Enrique Lima

  In the last month or so I have been able to test and experience first hand the offering from discountasp.net for hosted TFS 2010. This first part is a description of the setup process for the account itself and getting some additional information on what you will find through the portal on their site. Not long ago, I posted a little tidbit on hosting TFS.  Through it I also did a shameless plug to my employer, our services and the type of hosting we recommend.  So, wouldn’t me running on discountasp.net be an issue?  Actually? NO. Ok, enough rambling.  Let’s get some details here. It is a Software as a Service model.  Through it we get Source Control, Version Control, Work Item Tracking and such.  What about Build?  If your need includes Build Management and such, you may need to look at some other options.  But, still this is a great offering for those that are moving from SourceSafe.  Or organizations who have 3 to 5 developers on staff, and do not foresee getting larger anytime soon.  Can it support more than 5 developers?  Yes, but then we need to get into how are you using TFS.  Do you need more than just Basic?  For example, SharePoint and Reporting Services integration. The signup process was seamless! Very easy to follow, complete and transition to Visual Studio to start working. An email followed the signup process, it contained details on how to get to the Team Foundation Server Control Panel login.  Once there, here is what I saw after the initial setup process of naming my Team Project Collection: So, moving on … once I clicked the area to get my server info, I got the following: Then it was a matter of getting the first user in there: Then on to connecting Visual Studio to my hosted TFS. Getting the server information, and the user account created I will configure those options in Visual Studio. Using Team Explorer, I am adding a new server configuration. Once this is provided, click OK, I will be challenged for a username and password, provide them and you will land on the following screen. Then Click Close. You will now be connected to your server and Team Project Collection. Since this will likely be the first time connecting, you will have no Projects (I already have 2 going). Click Connect, and you will be back in Team Explorer. My next post in the topic will be on Creating your First Team Project and uploading a Project Template to the server.

• BizTalk 2010 Certification Exam

  - by Paul Petrov

  I took a shot at new (to me) certification exam for BizTalk 2010. I was able to pass it without any preparation just based on the experience. That does not mean this exam is a very simple one. Comparing to previous (2006 R2) it covers some new areas (like WCF) and has some demanding questions and situation to think about. But the most challenging factor is broad feature coverage. Overall, the impression that if BizTalk continues to grow in scope it’s better to create separate exams for core functionality and extended features (like EDI, RFID, LOB adapters) because it’s really hard to cover vast array of BizTalk capabilities. As far as required knowledge and questions allocation I think Microsoft description is on target. There were definitely more questions on deployment, configuration and administration aspects comparing to previous exam. WCF and WCF based adapters now play big role and this topic was covered well too. Extended functionality is claimed at 13% of the exam, I felt there were plenty of RFID questions but not many EDI, that’s why I thought it’d be useful to split exam into two to cover all of them equally. BRE is still there and good, cause it’s usually not very known/loved feature of the package. At the and, for those who plan to get certified, my advice would be to know all those areas of BizTalk for guaranteed passing: messaging and orchestrations, core adapters, routing, patterns; development of all artifacts and orchestrations; debugging and exceptions handling; packaging, deployment, tracking and administration; WCF bindings and adapters; BAM, BRE, RFID, EDI, etc. You may get by not knowing one smaller non-essential part (like I did with RFID, for example). In such case you better know all other areas very well to cover for the weak spot. If there more than one whiteouts in the knowledge it’s good idea to study and prepare: MSDN, blogs, virtual labs and good VM to play with can help when experience is not enough. So best wishes and good skill to you in passing this certification!

• Get Specific depth values in Kinect (XNA)

  - by N0xus

  I'm currently trying to make a hand / finger tracking with a kinect in XNA. For this, I need to be able to specify the depth range I want my program to render. I've looked about, and I cannot see how this is done. As far as I can tell, kinect's depth values only work with pre-set ranged found in the depthStream. What I would like to do is make it modular so that I can change the depth range my kinect renders. I know this has been down before but I can't find anything online that can show me how to do this. Could someone please help me out? I have made it possible to render the standard depth view with the kinect, and the method that I have made for converting the depth frame is as follows (I've a feeling its something in here I need to set) private byte[] ConvertDepthFrame(short[] depthFrame, DepthImageStream depthStream, int depthFrame32Length) { int tooNearDepth = depthStream.TooNearDepth; int tooFarDepth = depthStream.TooFarDepth; int unknownDepth = depthStream.UnknownDepth; byte[] depthFrame32 = new byte[depthFrame32Length]; for (int i16 = 0, i32 = 0; i16 < depthFrame.Length && i32 < depthFrame32.Length; i16++, i32 += 4) { int player = depthFrame[i16] & DepthImageFrame.PlayerIndexBitmask; int realDepth = depthFrame[i16] >> DepthImageFrame.PlayerIndexBitmaskWidth; // transform 13-bit depth information into an 8-bit intensity appropriate // for display (we disregard information in most significant bit) byte intensity = (byte)(~(realDepth >> 8)); if (player == 0 && realDepth == 00) { // white depthFrame32[i32 + RedIndex] = 255; depthFrame32[i32 + GreenIndex] = 255; depthFrame32[i32 + BlueIndex] = 255; } // omitted other if statements. Simple changed the color of the pixels if they went out of the pre=set depth values else { // tint the intensity by dividing by per-player values depthFrame32[i32 + RedIndex] = (byte)(intensity >> IntensityShiftByPlayerR[player]); depthFrame32[i32 + GreenIndex] = (byte)(intensity >> IntensityShiftByPlayerG[player]); depthFrame32[i32 + BlueIndex] = (byte)(intensity >> IntensityShiftByPlayerB[player]); } } return depthFrame32; } I have a strong hunch it's something I need to change in the int player and int realDepth values, but i can't be sure.

• How Big Data and Social Won the Election

  - by Mike Stiles

  The story of big data’s influence on the outcome of the US Presidential election is worth a good look, because a) it’s a harbinger of things to come, and b) it’s an example of similar successes available to any enterprise seriously resourcing integrated big data, modeling, and data-driven execution on all assets, including social. Obama campaign manager Jim Messina fielded a data and analytics brain trust 5 times larger than 2008. At that time, there were numerous databases from various sources, few of them talking to each other. This time, the mission was to be metrics-centered and measure everything measurable, and in context with all the other data. Big data showed them exactly what they needed to know and told them what to do about it. It showed them women 40-49 on the west coast would donate big money if they got to eat with George Clooney. Women on the east coast would pony up to hang out with Sarah Jessica Parker. Extensive daily modeling showed them what kinds of email appeals, from who, and to whom, would prove most successful in raising cash, recruiting volunteers, and getting out the vote. Swing state voters were profiled and approached with more customized targeting that at any time in history. Ads were purchased on specific shows watched by the targets, increasing efficiency 14% over traditional media buys. For all the criticism of the candidate’s focus on appearing on comedy and entertainment shows, and local radio morning shows, that’s where the data sent them to reach the voters most likely to turn out for them. And then there was social. Again, more than in any other election, Facebook was used for virtual, highly efficient door-to-door canvasing. Facebook fans got pictures of friends in swing states and were asked to encourage them to act. Using that approach, 1 in 5 peer-to-peer appeals led to the desired action. Assumptions, gut, intuition, campaign experience, all took a backseat to strategy shifts solidly backed up by data. Zeroing in on demographics likely to back the President and tracking their mood daily literally changed the voter landscape. The Romney team watched Obama voters appear seemingly out of thin air. One Obama campaign aide said, “We ran the election 66,000 times every night.” Which brings us to your organization. If you’re starting to feel like the battle-cry of “but this is the way we’ve always done it” is starting to put you in an extremely vulnerable position, you’re right. Social has become a key communication tool of the 21st century. Failing to use it, or failing to invest in a deep understanding of who your customers and prospects are so the content you post there will achieve desired actions and results, will leave you waking up one morning wondering, “What happened?”@mikestilesPhoto stock.xchng

• How can a solo programmer become a good team player?

  - by Nick

  I've been programming (obsessively) since I was 12. I am fairly knowledgeable across the spectrum of languages out there, from assembly, to C++, to Javascript, to Haskell, Lisp, and Qi. But all of my projects have been by myself. I got my degree in chemical engineering, not CS or computer engineering, but for the first time this fall I'll be working on a large programming project with other people, and I have no clue how to prepare. I've been using Windows all of my life, but this project is going to be very unix-y, so I purchased a Mac recently in the hopes of familiarizing myself with the environment. I was fortunate to participate in a hackathon with some friends this past year -- both CS majors -- and excitingly enough, we won. But I realized as I worked with them that their workflow was very different from mine. They used Git for version control. I had never used it at the time, but I've since learned all that I can about it. They also used a lot of frameworks and libraries. I had to learn what Rails was pretty much overnight for the hackathon (on the other hand, they didn't know what lexical scoping or closures were). All of our code worked well, but they didn't understand mine, and I didn't understand theirs. I hear references to things that real programmers do on a daily basis -- unit testing, code reviews, but I only have the vaguest sense of what these are. I normally don't have many bugs in my little projects, so I have never needed a bug tracking system or tests for them. And the last thing is that it takes me a long time to understand other people's code. Variable naming conventions (that vary with each new language) are difficult (__mzkwpSomRidicAbbrev), and I find the loose coupling difficult. That's not to say I don't loosely couple things -- I think I'm quite good at it for my own work, but when I download something like the Linux kernel or the Chromium source code to look at it, I spend hours trying to figure out how all of these oddly named directories and files connect. It's a programming sin to reinvent the wheel, but I often find it's just quicker to write up the functionality myself than to spend hours dissecting some library. Obviously, people who do this for a living don't have these problems, and I'll need to get to that point myself. Question: What are some steps that I can take to begin "integrating" with everyone else? Thanks!

• Do you know about the Visual Studio 2010 Database Projects Guidance?

  - by Martin Hinshelwood

  Early on in the Team System (now Visual Studio ALM) cycle a new product surfaced within Team System that was affectionately called “Data Dude”, but had the more formal name of “Visual Studio 2005 Team Edition for Database Professionals”. The purpose of this product was to try and make the database a “first class citizen” in the development world. Those that started using Visual Studio 2005 Team Edition for Database Professionals (Data Dude) loved it, but everyone else did not get it. The capabilities were a little patchy, but the one thing it did bring to the party was the ability to put your database schema under source control. This was revolutionary as previously your DBA sat as far away from the team as possible, and usually in a dark cupboard, now they could partake of all the goodness of Version Control, Work Item Tracking and automated builds. The problem was that the understanding required to manage these projects was very different to that needed previously. Then the Visual Studio ALM Rangers got a hold of it…and produced some of the best guidance available. Figure: Download the guidance from http://vsdatabaseguide.codeplex.com/ This guidance discusses scenarios and approaches of using the Database Projects in Visual Studio 2010 to help you use the tools more effectively and maximize their value to your organization This guidance is focused on these five areas: Solution and Project Management Source Code Control and Configuration Management Integrating External Changes with the Project System Build and Deployment Automation with Visual Studio Database Projects Database Testing and Deployment Verification Each of these areas has common guidance, usage scenarios, hands on labs, and lessons learned from real world engagements and the community discussions.   The guidance is broken down into three packages: Guidance documentation Hands-on-lab (HOL) documentation note: The documentation is available in XPS-only format packages or complete XPS,PDF,DOCX format packages HOL Package If you need assistance and no one else can help, then you may need to call the Visual Studio ALM Rangers. The Visual Studio ALM Rangers have the mission to provide out of band solutions for missing features or guidance. They are supported by Microsoft Product Group, Microsoft Consulting Services, Microsoft Most Valued Professionals (MVPs) and technical specialists from technology communities around the globe, giving you a real-world view from the field, where the technology has been tested and used.

• Reduce weight in healthy way - Day 2

  - by krnites

  My second day of reducing weight and it seems most of the blog are correct in saying that you can reduce weight if your calorie consumption is less than what you burn. In one day I have lost 1 lbs without doing anything. My current weight is 177.4 lbs. Yesterday I ate small portion of dinner that I used to eat that also around 7 PM. Normally I eat my dinner around 10 PM and withing 2 hour of eating I go for sleep, but yesterday I ate around 7 PM and went for sleep only after 12.On my second day I have eaten noodles and 3 eggs in breakfast and sesame chicken ( I love it) and fried rice in lunch, I still have not gone for running but had plan to go for running and then swimming. I hope it will at least burn the calories that I had taken. On some site it was written that a normal men body needs around 2000 Calorie a day. So if I am eating less than 2000 calorie ( noodles + 3 eggs = 400+200, rice + sesame chicken = 1300, total = 1900) and burning around 300 calorie, my total calorie intake will be 1600 which is less than what my body needs. So most probably by tomorrow I should come under 176 lb bracket.Apart from counting the calorie that I am taking in everyday and approx number of calorie that I am burning everyday, I had also starting tracking my physical activities on my mobile. I have got a beautiful Samsung Focus S Windows 7.5 mobile. And after browsing through the market I have downloaded couple of health Apps.1. 6 Week training - this has set of exercise and lets you choose the number of sets you want to do for all exercise. Its focus on your core muscles.2. Fast food Calories - This apps has all the fast food chain listed and give the calorie count of each of the food item available on there menu. Like for Burger King's French Fries Large (Salted) contains 500 Calorie.3. Gym Pocket Guide - Contains instructions for different kind of exercise and tells a right way of doing them.4.  RunSat - kind of GPS based application. Its mark the distance you have run, shows the path you have taken on a map, total calorie burnt, laps completed. I love this apps.5. Stop Watch I also have noticed that If I am running in GYM and have television in front of me where a movie or serial is going on which I like,  I normally didn't notice the time. Most of the time running on treadmill is very boring, but if some music video is playing or some kind of sitcom is going, I can run for  a hour or half.So on day 2 I have lost 1 lbs and had learnt that calorie intake should be less then calorie burnt for a given day.

• Application Integration Future &ndash; BizTalk Server &amp; Windows Azure (TechEd 2012)

  - by SURESH GIRIRAJAN

  I am really excited to see lot of new news around BizTalk in TechEd 2012. I was recently watching the session presented by Sriram and Rajesh on “Application Integration Futures: The Road Map and What's Next on Windows Azure”. It was great session and lot of interesting stuff about the feature updates for BizTalk and Azure integration. I have highlighted them below, definitely customers who haven’t started using Microsoft BizTalk ESB Toolkit should start using them which is going to be part of the core BizTalk product in future release, which is cool… BizTalk Server feature enhancements Manageability: ESB Tool Kit is going to be part of the core BizTalk product and Setup. Visualize BizTalk artifact dependencies in BizTalk administration console. HIS administration using configuration files. Performance: Improvements in ordered send port scenarios Improved performance in dynamic send ports and ESB, also to configure BizTalk host handler for dynamic send ports. Right now it runs under default host, which does not enable to scale. MLLP adapter enhancements and DB2 client transaction load balancing / client bulk insert. Platform Support: Visual Studio 2012, Windows 8 Server, SQL Server 2012, Office 15 and System Center 2012. B2B enhancements to support latest industry standards natively. Connectivity Improvements: Consume REST service directly in BizTalk SharePoint integration made easier. Improvements to SMTP adapter, to add macros for sending same email with different content to different parties. Connectivity to Azure Service Bus relay, queues and topics. DB2 client connectivity to SQL Server and SQL Server connectivity to Informix. CICS Http client connectivity to Windows. Azure: Use Azure as IaaS/PaaS for BizTalk environment. Use Azure to provision BizTalk environment for test environment / development. Later move to On-premises or build a Hybrid cloud approach. Eliminate HW procurement for BizTalk environment for testing / demos / development etc. Enable to create BizTalk farm easily and remove/add more servers as needed. EAI Service: EAI Bridge Protocol transformation Message Transformation Running custom code Message Enrichment Hybrid Connectivity LOB Applications On-premises Application On-premises Connectivity to Applications in the cloud Queues/ Topics Ftp Devices Web Services Bridge can be customized based on the service needs to provide different capabilities needed as part of the bridge. Look at the sample for EDI bridge for EDI service sample. Also with Tracking enabled through the portal. http://msdn.microsoft.com/en-us/library/windowsazure/hh674490 Adapters: Service Bus Messaging adapter - New adapter added. WebHttp adapter - For REST services. NetTcpRelay adapter - New adapter added. I will start posting more and once I start playing with this…

• Our Favorite Highlights from OpenWorld 2012

  - by Kathy.Miedema

  By Kathy Miedema and Misha Vaughan, Oracle Applications User Experience The Oracle Applications User Experience (UX) team’s activities around OpenWorld expand every year, but this year we certainly raised the bar.   Members of our team helped deliver three, separate, all-day training events in the week prior to OpenWorld. Our Fusion User Experience Advocates (FXA) and Applications UX Sales Ambassadors (SAMBA) have all-new material around the Oracle user experience to deliver at conferences in the coming year - Fusion Applications design patterns, mobile design patterns, and the new face of Fusion. We also delivered a hands-on workshop sharing user experience tools for our customers that is designed to answer this question: "If I have no UX staff, what do I do?" We also spent the weeks just before OpenWorld preparing to talk about the new face of Fusion Applications, a greatly simplified entry experience into Fusion Applications for self-service users, CRM users, and IT managers who want to change the look and feel quickly. Special thanks to Oracle ACE Director Floyd Teter for the first mention of our project.Jeremy Ashley, VP, Oracle Applications User Experience Customers may have seen one of the many OpenWorld session demos of the new face of Fusion, which will be available with Fusion Applications soon. It was shown in sessions by Oracle's Chris Leone, Anthony Lye, and our own Vice President, Jeremy Ashley, among others.   Leone reinforced the importance of user experience as one of three main design principles for Fusion Applications, emphasizing that Fusion was designed from the beginning to be intelligent, social, and mobile. User experience highlights of the new face of Fusion, he said, included the need for "zero training," and he called the experience "easy to use." He added that deploying it for HCM self-service would be effortless.  Customers take part in a usability lab tour during OpenWorld 2012. Customers also may have seen the new face of Fusion on the demogrounds or during one of our teams' chartered lab tours at the end of the week. We tested other new designs at our on-site lab in the Intercontinental Hotel, next to Moscone West. Applications User Experience team members show eye-tracking and mobile demos at OOW. We were also excited to kick off new branches of the Oracle Usability Advisory Board, which now has groups in Latin America and the Middle East, in addition to North America and EMEA.   And we were pleasantly surprised by the interest in one of our latest research projects, Oracle Voice, which is designed to enable faster data input for on-the-go users. We offer a big thank-you to the Nuance demopod for sharing the demo with OpenWorld attendees.  For more information on our program and products like the new face of Fusion, please comment below.

• How to deal with Warning : "Uncommittable transaction is detected at the end of the batch. The trans

  - by VishnuTiwariBlog

  Hi, If you are integrating with SQL Server and dealing with batch messages, you may encounter this problem. And this is evitable. The reason is the contention of resources. If your batch contains four messages and all the four messages have to be updated to SQL Server and then at the same time four process will contend for SQL server table and resources and the obvious result will be, few of your transaction will be left uncomitted and if you are not handling dehydration [not modifying the default property of the Dehydration] then your orchestration will dehydrate and will go for retry. If retry is set for every five minutes then after five minutes Port will send the message to the database. Reason for writing this post was as I did not want to see so many DEHYDRATED messages. And this was happening as Host Throttling was not set. Thus as soon as the BizTalk Process finds that SQL resources are unavailable it will go and dehydrate that process and process will go for retry. The contension of resources is unavoidable though we can fine tune the Dehydration setting. If you increase the time that an orchestration can be blocked at a subscription before being dehydrated, possibly you will give more time BizTalk Engine to handle to SQL resource availability. At least I solve the problem by fine tuning the Dehydration properties. Below is the section of config info which you need to add to the BTSNTsvc.exe.config.   <?xml version="1.0" ?> <configuration>        <configSections>               <section name="xlangs" type="Microsoft.XLANGs.BizTalk.CrossProcess.XmlSerializationConfigurationSectionHandler, Microsoft.XLANGs.BizTalk.CrossProcess" />        </configSections>        <runtime>               <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">                      <probing privatePath="BizTalk Assemblies;Developer Tools;Tracking" />               </assemblyBinding>        </runtime>        <xlangs>               <Configuration>                      <Dehydration MaxThreshold="1800" MinThreshold="1" ConstantThreshold="-1">                             <VirtualMemoryThrottlingCriteria OptimalUsage="900" MaximalUsage="1300" IsActive="true" />                             <PrivateMemoryThrottlingCriteria OptimalUsage="50" MaximalUsage="350" IsActive="true" />                             <PhysicalMemoryThrottlingCriteria OptimalUsage="50" MaximalUsage="350" IsActive="false" />                      </Dehydration>               </Configuration>        </xlangs> </configuration>

• The only metric with any value

What's the velocity? How big is a story point?  How many story points is that team producing per man hour?   People are sadly missing the whole point.  Take your measurements up a level or two.  When you get down to it, the only metric that makes any difference, is ROI.   The problem is that often times, the developers work in a dark hole, far removed from the realities of how exactly they get paid.  A bigger problem is that mid-level managers tend to be further removed from the realities of ROI.  A lot of times mid-level managers get tasked with tracking their teams "productivity" using things like, "lines of code", or "completeness of the productivity reports."   Monetize your projects and then track your velocity against business value (real dollars).    When your development teams can say, "Last year, our team cost the business 2 million dollars and we know that because of our efforts, the company saved 2 million dollars in waste and increased revenues by another 4 million dollars." At that point you have just moved your development team from a cost center, to a profit center.  You might have to give them a raise, but they have demonstrated that they have earned it.

• Should a server "be lenient" in what it accepts and "discard faulty input silently"?

  - by romkyns

  I was under the impression that by now everyone agrees this maxim was a mistake. But I recently saw this answer which has a "be lenient" comment upvoted 137 times (as of today). In my opinion, the leniency in what browsers accept was the direct cause of the utter mess that HTML and some other web standards were a few years ago, and have only recently begun to properly crystallize out of that mess. The way I see it, being lenient in what you accept will lead to this. The second part of the maxim is "discard faulty input silently, without returning an error message unless this is required by the specification", and this feels borderline offensive. Any programmer who has banged their head on the wall when something fails silently will know what I mean. So, am I completely wrong about this? Should my program be lenient in what it accepts and swallow errors silently? Or am I mis-interpreting what this is supposed to mean? The original question said "program", and I take everyone's point about that. It can make sense for programs to be lenient. What I really meant, however, is APIs: interfaces exposed to other programs, rather than people. HTTP is an example. The protocol is an interface that only other programs use. People never directly provide the dates that go into headers like "If-Modified-Since". So, the question is: should the server implementing a standard be lenient and allow dates in several other formats, in addition to the one that's actually required by the standard? I believe the "be lenient" is supposed to apply to this situation, rather than human interfaces. If the server is lenient, it might seem like an overall improvement, but I think in practice it only leads to client implementations that end up relying on the leniency and thus failing to work with another server that's lenient in slightly different ways. So, should a server exposing some API be lenient or is that a very bad idea? Now onto lenient handling of user input. Consider YouTrack (a bug tracking software). It uses a language for text entry that is reminiscent of Markdown. Except that it's "lenient". For example, writing - foo - bar - baz is not a documented way of creating a bulleted list, and yet it worked. Consequently, it ended up being used a lot throughout our internal bugtracker. Next version comes out, and this lenient feature starts working slightly differently, breaking a bunch of lists that (mis)used this (non)feature. The documented way to create bulleted lists still works, of course. So, should my software be lenient in what user inputs it accepts?

• SOA Summit - Oracle Session Replay

  - by Bruce Tierney

  If you think you missed the most recent Integration Developer News (IDN) "SOA Summit" 2013...good news, you didn't.  At least not the replay of the Oracle session titled: Three Solutionsfor Simplifying Cloud/On-Premises Integration As you will see in the reply below, this session introduces Three common reasons for integration complexity: Disparate Toolkits Lack of API Management Rigid, Brittle Infrastructure and then the Three solutions to these challenges: Unify Cloud On-premises Integration Enable Multi-channel Development with API Management Plan for the Unexpected - Future Readiness The last solution on future readiness describes how you can transition from being reactive to new trends, such as the Internet of Things (IoT), by modifying your integration strategy to enable business agility and how to recognize trends through Fast Data event processing ahead of your competition. Oracle SOA Suite customer SFpark's (San Francisco Metropolitan Transit Authority) implementation with API Management is covered as shown in the screenshot to the right This case study covers the core areas of API Management for partners to build their own applications by leveraging parking availability and real-time pricing as well as mobile enablement of data integrated by SOA Suite underneath.  Download the free SFpark app from the Apple and Android app stores to check it out. When looking into the future, the discussion starts with a historical look to better prepare for what comes next.   As shown in the image below, one of the next frontiers after mobile and cloud integration is a deeper level of direct "enterprise to customer" interaction.  Much of this relates to the Internet of Things.  Examples of IoT from the perspective of SOA and integration is also covered in the session. For example, early adopter Turkcell and their tracking of mobile phone users as they move from point A to B to C is shown in the image the right.   As you look into more "smart services" such as Location-Based Services, how "future ready" is your application infrastructure?  . . . Check out the replay by clicking the video image below to learn about these three challenges and solution including how to "future ready" your application infrastructure:

Using event markers enables GoldenGate processes to take a defined action based on an event in the data stream. This feature within Oracle GoldenGate simplifies methods to embed specific custom processing in the areas of error handling, alerts, and notification. The event marker system effectively allows for DML driven workflows to be created within GoldenGate and enables customers to craft non-standard processing based on special events. There are a number of supported event actions including: trace, log, checkpoint before, suspend, abort, and several others. With 11gR1 events can now be triggered by DDL operations, plus variables can be passed in and out of the system to shell scripts. Some good use cases for this feature are Automatic switchover to the secondary system during planned outages Better monitoring over source systems’ performance and automated switchover to the standby system in case of an outage with the primary system Automatic switchover from initial load to changed data movement Automatic synchronization of any type of batch processing taking place on both the source and target databases for database consistency Automatic stoppage of the Delivery module to allow end-of-day reporting Finding, tracking, and reporting on transactions that are of interest including the ones that do not have primary keys or transaction record numbers If you would like to see a demo, please visit our youtube channel (http://youtube.com/oraclegoldengate)  To learn more about the new features of Oracle GoldenGate 11gR2 and to ask questions to the PM team, please join us on September 12th  8am or 10am PST for our live webcast.

• Software Architecture Analysis Method (SAAM)

  Software Architecture Analysis Method (SAAM) is a methodology used to determine how specific application quality attributes were achieved and how possible changes in the future will affect quality attributes based on hypothetical cases studies. Common quality attributes that can be utilized by this methodology include modifiability, robustness, portability, and extensibility. Quality Attribute: Application Modifiability The Modifiability quality attribute refers to how easy it changing the system in the future will be. This to me is a very open-ended attribute because a business could decide to transform a Point of Sale (POS) system in to a Lead Tracking system overnight. (Yes, this did actually happen to me) In order for SAAM to be properly applied for checking this attribute specific hypothetical case studies need to be created and review for the modifiability attribute due to the fact that various scenarios would return various results based on the amount of changes. In the case of the POS change out a payment gateway or adding an additional payment would have scored very high in comparison to changing the system over to a lead management system. I personally would evaluate this quality attribute based on the S.O.I.L.D Principles of software design. I have found from my experience the use of S.O.I.L.D in software design allows for the adoption of changes within a system. Quality Attribute: Application Robustness The Robustness quality attribute refers to how an application handles the unexpected. The unexpected can be defined but is not limited to anything not anticipated in the originating design of the system. For example: Bad Data, Limited to no network connectivity, invalid permissions, or any unexpected application exceptions. I would personally evaluate this quality attribute based on how the system handled the exceptions. Robustness Considerations Did the system stop or did it handle the unexpected error? Did the system log the unexpected error for future debugging? What message did the user receive about the error? Quality Attribute: Application Portability The Portability quality attribute refers to the ease of porting an application to run in a new operating system or device. For example, It is much easier to alter an ASP.net website to be accessible by a PC, Mac, IPhone, Android Phone, Mini PC, or Table in comparison to desktop application written in VB.net because a lot more work would be involved to get the desktop app to the point where it would be viable to port the application over to the various environments and devices. I would personally evaluate this quality attribute based on each new environment for which the hypothetical case study identifies. I would pay particular attention to the following items. Portability Considerations Hardware Dependencies Operating System Dependencies Data Source Dependencies Network Dependencies and Availabilities  Quality Attribute: Application Extensibility The Extensibility quality attribute refers to the ease of adding new features to an existing application without impacting existing functionality. I would personally evaluate this quality attribute based on each new environment for the following Extensibility  Considerations Hard coded Variables versus Configurable variables Application Documentation (External Documents and Codebase Documentation.) The use of Solid Design Principles

• SMTP POP3 & PST. Acronyms from Hades.

  - by mikef

  A busy SysAdmin will occasionally have reason to curse SMTP. It is, certainly, one of the strangest events in the history of IT that such a deeply flawed system, designed originally purely for campus use, should have reached its current dominant position. The explanation was that it was the first open-standard email system, so SMTP/POP3 became the internet standard. We are, in consequence, dogged with a system with security weaknesses so extreme that messages are sent in plain text and you have no real assurance as to who the message came from anyway (SMTP-AUTH hasn't really caught on). Even without the security issues, the use of SMTP in an office environment provides a management nightmare to all commercial users responsible for complying with all regulations that control the conduct of business: such as tracking, retaining, and recording company documents. SMTP mail developed from various Unix-based systems designed for campus use that took the mail analogy so literally that mail messages were actually delivered to the users, using a 'store and forward' mechanism. This meant that, from the start, the end user had to store, manage and delete messages. This is a problem that has passed through all the releases of MS Outlook: It has to be able to manage mail locally in the dreaded PST file. As a stand-alone system, Outlook is flawed by its neglect of any means of automatic backup. Previous Outlook PST files actually blew up without warning when they reached the 2 Gig limit and became corrupted and inaccessible, leading to a thriving industry of 3rd party tools to clear up the mess. Microsoft Exchange is, of course, a server-based system. Emails are less likely to be lost in such a system if it is properly run. However, there is nothing to stop users from using local PSTs as well. There is the additional temptation to load emails into mobile devices, or USB keys for off-line working. The result is that the System Administrator is faced by a complex hybrid system where backups have to be taken from Servers, and PCs scattered around the network, where duplication of emails causes storage issues, and document retention policies become impossible to manage. If one adds to that the complexity of mobile phone email readers and mail synchronization, the problem is daunting. It is hardly surprising that the mood darkens when SysAdmins meet and discuss PST Hell. If you were promoted to the task of tormenting the souls of the damned in Hades, what aspects of the management of Outlook would you find most useful for your task? I'd love to hear from you. Cheers, Michael

• Sampling SQL server batch activity

  - by extended_events

  Recently I was troubleshooting a performance issue on an internal tracking workload and needed to collect some very low level events over a period of 3-4 hours.  During analysis of the data I found that a common pattern I was using was to find a batch with a duration that was longer than average and follow all the events it produced.  This pattern got me thinking that I was discarding a substantial amount of event data that had been collected, and that it would be great to be able to reduce the collection overhead on the server if I could still get all activity from some batches. In the past I’ve used a sampling technique based on the counter predicate to build a baseline of overall activity (see Mikes post here).  This isn’t exactly what I want though as there would certainly be events from a particular batch that wouldn’t pass the predicate.  What I need is a way to identify streams of work and select say one in ten of them to watch, and sql server provides just such a mechanism: session_id.  Session_id is a server assigned integer that is bound to a connection at login and lasts until logout.  So by combining the session_id predicate source and the divides_by_uint64 predicate comparator we can limit collection, and still get all the events in batches for investigation. CREATE EVENT SESSION session_10_percent ON SERVER ADD EVENT sqlserver.sql_statement_starting(     WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlos.wait_info (        WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlos.wait_info_external (        WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlserver.sql_statement_completed(     WHERE (package0.divides_by_uint64(sqlserver.session_id,10))) ADD TARGET ring_buffer WITH (MAX_DISPATCH_LATENCY=30 SECONDS,TRACK_CAUSALITY=ON) GO   There we go; event collection is reduced while still providing enough information to find the root of the problem.  By the way the performance issue turned out to be an IO issue, and the session definition above was more than enough to show long waits on PAGEIOLATCH*.

• Building Enterprise Smartphone App &ndash; Part 3: Key Concerns

  - by Tim Murphy

  This is part 3 in a series of posts based on a talk I gave recently at the Chicago Information Technology Architects Group.  Feel free to leave feedback. Keys Concerns Of Smartphones In The Enterprise These are the factors that you need to be aware of and address in order to build successful enterprise smartphone applications.  Most of them have nothing to do with the application itself as you will see here. Managing Devices Managing devices is a factor that is going to effect how much your company will have to spend outside of developing the applications.  How will you track the devices within the corporation?  How often will you have to replace phones and as a consequence have to upgrade your applications to support new phones?  The devices can represent a significant investment of capital.  If these questions are not addressed you will find a number of hidden costs throughout the life of your solution. Purchase or BYOD We have seen the trend of Bring Your Own Device (BYOD) lately within the enterprise.  How many meetings have you been in where someone is on their personal iPad, iPhone, Android phone or Windows Phone?  The issue is if you can afford to support everyone's choice in device? That is a lot to take on even if you only support the current release of each platform. Do you go with the most popular device or do you pick a platform that best matches your current ecosystem and distribute company owned devices?  There is no easy answer here, but you should be able give some dollar value to both hardware and development costs related to platform coverage. Asset Tracking/Insurance Smartphones are devices that are easier to lose or have stolen than laptops and desktops. Not only do you have your normal asset management concerns but also assignment of financial responsibility. You also will need to insure them against damage and theft and add legal documents that spell out the responsibilities of the employees that use these devices. Personal vs. Corporate Data What happens when you terminate an employee?  How do you recover the device?  What happens when they have put personal data on the device?  These are all situation that can cause possible loss of corporate intellectual property or legal repercussions of reclaiming a device with personal data on it.  Policies need to be put in place that protect the company from being exposed to type of loss.  This can mean significant legal and procedural cost that you need to consider. Coming Up In the last installment of this series I will cover application development considerations. del.icio.us Tags: Smartphones,Enterprise Smartphone Apps,Architecture

• Google Streetview under V3 Code having hiccups and delays

  - by jeffkee

  http://new.brocksmeaton.com/showlisting.php/196/-7210-Arbutus-Place-Whytecliff-West-Vancouver-west-vancouver-real-estate The really odd thing is I had this working yesterday and today it's not working. I'm using jQuery UI to switch the tabs on the location map/street view module. I've recently upgraded the Google Maps code as well as the Google Streetview code to version 3. So when I open it in Firefox, with Firebug on, as soon as I switch to the Streetview tab, the navigation and zoom in out controls show, but nothing shows.. and then when I try to drag the map around, it does not move around, but instead, causes errors in Firebug: "too much recursion". So it causes the whole browser to become buggy, slows down, and the errors happen, and nothing shows on the streetview pane. Most of the map loading code is located in inline Javascript on the page itself. Some of the code is under showlisting.js <script type="text/javascript" src="/js/showlisting.js"></script> <script type="text/javascript"> // Call this function when the page has been loaded function loadmap() { var latlng = new google.maps.LatLng(49.374918567425475, -123.28996885871596); var myOptions = { zoom: 14, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById('listingmap'), myOptions); var listingicon = '/images/activehouse.png'; var infowindow = new google.maps.InfoWindow(); homemarker = new google.maps.Marker({position: latlng, map: map, icon: listingicon}); google.maps.event.addListener(homemarker, 'click', function() { infowindow.setContent('<div style="height:80px; width:250px; color:#333;"><p>7210 Arbutus Place<br />Whytecliff, West Vancouver</div>') infowindow.open(map,homemarker); }); } function loadpano() { var latlng = new google.maps.LatLng(49.374918567425475, -123.28996885871596); $('#listingpanorama').slideDown(500, function() { var panoramaOptions = { addressControl:false, position: latlng, pov: { heading: 34, pitch: 30, zoom: 1 } }; var panorama = new google.maps.StreetViewPanorama(document.getElementById('listingpanorama'), panoramaOptions); }); return false; } </script> My old one under GOogle API Version 2 is here FYI if you want to take a look at it: http://demo.brixwork.com/master/showlisting.php/63/1701-388-Drake-Street-False-Creek-North-Vancouver-

• How to program a real-time accurate audio sequencer on the iphone?

  - by Walchy

  Hi... I want to program a simple audio sequencer on the iphone but I can't get accurate timing. The last days I tried all possible audio techniques on the iphone, starting from AudioServicesPlaySystemSound and AVAudioPlayer and OpenAL to AudioQueues. In my last attempt I tried the CocosDenshion sound engine which uses openAL and allows to load sounds into multiple buffers and then play them whenever needed. Here is the basic code: init: int channelGroups[1]; channelGroups[0] = 8; soundEngine = [[CDSoundEngine alloc] init:channelGroups channelGroupTotal:1]; int i=0; for(NSString *soundName in [NSArray arrayWithObjects:@"base1", @"snare1", @"hihat1", @"dit", @"snare", nil]) { [soundEngine loadBuffer:i fileName:soundName fileType:@"wav"]; i++; } [NSTimer scheduledTimerWithTimeInterval:0.14 target:self selector:@selector(drumLoop:) userInfo:nil repeats:YES]; In the initialisation I create the sound engine, load some sounds to different buffers and then establish the sequencer loop with NSTimer. audio loop: - (void)drumLoop:(NSTimer *)timer { for(int track=0; track<4; track++) { unsigned char note=pattern[track][step]; if(note) [soundEngine playSound:note-1 channelGroupId:0 pitch:1.0f pan:.5 gain:1.0 loop:NO]; } if(++step>=16) step=0; } Thats it and it works as it should BUT the timing is shaky and instable. As soon as something else happens (i.g. drawing in a view) it goes out of sync. As I understand the sound engine and openAL the buffers are loaded (in the init code) and then are ready to start immediately with alSourcePlay(source); - so the problem may be with NSTimer? Now there are dozens of sound sequencer apps in the appstore and they have accurate timing. I.g. "idrum" has a perfect stable beat even in 180 bpm when zooming and drawing is done. So there must be a solution. Does anybody has any idea? Thanks for any help in advance! Best regards, Walchy

• Android USB Host Communication

  - by Kip Russell

  I'm working on a project that utilizes the USB Host capabilities in Android 3.2. I'm suffering from a deplorable lack of knowledge and talent regarding USB/Serial communication in general. I'm also unable to find any good example code for what I need to do. I need to read from a USB Communication Device. Ex: When I connect via Putty (on my PC) I enter: >GO And the device starts spewing out data for me. Pitch/Roll/Temp/Checksum. Ex: $R1.217P-0.986T26.3*60 $R1.217P-0.986T26.3*60 $R1.217P-0.987T26.3*61 $R1.217P-0.986T26.3*60 $R1.217P-0.985T26.3*63 I can send the initial 'GO' command from the Android device at which time I receive an echo of 'GO'. Then nothing else on any subsequent reads. How can I: 1) Send the 'go' command. 2) Read in the stream of data that results. The USB device I'm working with has the following interfaces (endpoints). Device Class: Communication Device (0x2) Interfaces: Interface #0 Class: Communication Device (0x2) Endpoint #0 Direction: Inbound (0x80) Type: Intrrupt (0x3) Poll Interval: 255 Max Packet Size: 32 Attributes: 000000011 Interface #1 Class: Communication Device Class (CDC) (0xa) Endpoint #0 Address: 129 Number: 1 Direction: Inbound (0x80) Type: Bulk (0x2) Poll Interval (0) Max Packet Size: 32 Attributes: 000000010 Endpoint #1 Address: 2 Number: 2 Direction: Outbound (0x0) Type: Bulk (0x2) Poll Interval (0) Max Packet Size: 32 Attributes: 000000010 I'm able to deal with permission, connect to the device, find the correct interface and assign the endpoints. I'm just having trouble figuring out which technique to use to send the initial command read the ensuing data. I'm tried different combinations of bulkTransfer and controlTransfer with no luck. Thanks. I'm using interface#1 as seen below: public AcmDevice(UsbDeviceConnection usbDeviceConnection, UsbInterface usbInterface) { Preconditions.checkState(usbDeviceConnection.claimInterface(usbInterface, true)); this.usbDeviceConnection = usbDeviceConnection; UsbEndpoint epOut = null; UsbEndpoint epIn = null; // look for our bulk endpoints for (int i = 0; i < usbInterface.getEndpointCount(); i++) { UsbEndpoint ep = usbInterface.getEndpoint(i); Log.d(TAG, "EP " + i + ": " + ep.getType()); if (ep.getType() == UsbConstants.USB_ENDPOINT_XFER_BULK) { if (ep.getDirection() == UsbConstants.USB_DIR_OUT) { epOut = ep; } else if (ep.getDirection() == UsbConstants.USB_DIR_IN) { epIn = ep; } } } if (epOut == null || epIn == null) { throw new IllegalArgumentException("Not all endpoints found."); } AcmReader acmReader = new AcmReader(usbDeviceConnection, epIn); AcmWriter acmWriter = new AcmWriter(usbDeviceConnection, epOut); reader = new BufferedReader(acmReader); writer = new BufferedWriter(acmWriter); }
