• Oracle BPM and Open Data integration development

  - by drrwebber

  Rapidly developing Oracle BPM application solutions with data source integration previously required significant Java and JDeveloper skills. Now using open source tools for open data development significantly reduces the coding needed.  Key tasks can be performed with visual drag and drop designing combined with menu selections entry and automatic form generation directly from XSD schema definitions. The architecture used is extremely lightweight, portable, open platform and scalable allowing integration with a variety of Oracle and non-Oracle data sources and systems. Two videos available on YouTube walk through the process at both an introductory conceptual level and then a deep dive into the programming needed using JDeveloper, Oracle BPM composer and Oracle WLS (WebLogic Server) along with the CAM editor and Open-XDX open source tools. Also available are coding samples and resources from the GitHub project page, along with working online demonstration resources on the VerifyXML site. Combining Oracle BPM with these open source tools provides a comprehensive simple and elegant solution set. Development times are slashed and rapid prototyping is enabled. Also existing data sources can be integrated using open data formats with either XML or JSON along with CRUD accessing via the Open-XDX Java component. The Open-XDX tool is a code-free approach where data mapping is configured as templates using visual drag and drop in the CAM Editor open source tool.  XML or JSON is then automatically generated or processed (output or input) and appropriate SQL statements created to support the data accessing.   Also included is the ability to integrate with fillable PDF forms via the XML templates and the Java PDF form filling library.  Again minimal Java coding is needed to associate the XML source content with the PDF named fields.  The Oracle BPM forms can be automatically generated from XSD schema definitions that are built from the data mapping templates.  This dramatically simplifies development work as all the integration artifacts needed are created by the open source editor toolset. The developer level video is designed as a tutorial with segments, hands-on demonstrations and reviews.  This allows developers to learn the techniques and approaches used in incremental steps. The intended audience ranges from data analysts to developers and assumes only entry level Java skills and knowledge.  Most actions are menu driven while Java coding is limited to simply configuring values and parameters along with performing builds and deployments from JDeveloper and Oracle WLS.   Additional existing Oracle online training resources can be referenced on Oracle BPM and WLS that cover other normal delivery aspects such as user management and application deployment.

  The usb port in the back of my laptop (on the right side when viewed from using perspective) is not working. Does anybody know if we can get this port working, and what the port number is.

The two usb ports on the left work just fine. EDIT: I just updated my bios from 1.32 to 1.39, no change in behaviour. The port does not even power up my devices. EDIT 2: Booted up windows, and the port is working. I went into the device manager and looked at the USB settings. I found my USB drive on Port 2, Hub 3, i just don't know how that relates to the Bus and Device numbers of linux. In windows, Smart card reader was on USB hub located at port 1 hub 2, fingerprint and bluetooth were on USB hub located at port 1 hub 1 EDIT 3: Went and looked at this SO post. Tried to look at my kern.log file with tail -f /var/log/kern.log. Got some activity when plugging/removing devices in other ports, but nothing happens when connecting a device into that port. It really looks disabled. Looked at my usb1-4 sys/bus/usb/devices/usb1/power/control and they are all set on auto. As expected, usb4 have version 3.00, the others (usb1-usb3) are 2.00.

• WHERE x = @x OR @x IS NULL

  - by steveh99999

  Every SQL DBA and developer should read the blog of MVP Erland Sommarskog – but particularly  his article on dynamic search conditions in T-SQL. I’ve linked above to his SQL 2005 article but his 2008 version is also a must-read. I seem to regularly come across uses of the SQL in the title above… Erland’s article explains in detail why this is inefficient, but I came across a nice example recently… A stored procedure contained the following code :- WHERE @Name is null or [Name] like @Name as a nonclustered index exists on the Name column, you might assume this would be handled efficiently by SQL Server. However, I got the following output from SET STATISTICS IO Table 'xxxxx'. Scan count 15, logical reads 47760, physical reads 9, read-ahead reads 13872, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Note the high number of logical reads… After a bit of investigation, we found that @Name could never actually be set to NULL in this particular example. ie the @x IS NULL was spurious… So, we changed the call to WHERE  [Name] like @Name Now, how much more efficient is this code ? Table 'xxxxx'. Scan count 3, logical reads 24, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0 A nice easy win in this case…… a full index scan has been replaced by a significantly more efficient index seek. I managed to recreate the same behaviour on Adventureworks – here’s a quick query to demonstrate :- USE adventureworks SET STATISTICS IO ON DECLARE @id INT = 51721 SELECT * FROM Sales.SalesOrderDetail WHERE @id IS NULL OR salesorderid = @id SELECT * FROM Sales.SalesOrderDetail WHERE salesorderid = @id Take a look at the STATISTICS IO output and compare the actual query plans used to prove the impact of  WHERE @id IS NULL. And just to follow some of Erland’s advice – here’s how you could get similar performance if it was possible that @id could actually sometimes contain NULL. DECLARE @sql NVARCHAR(4000), @parameterlist NVARCHAR(4000) DECLARE @id INT = 51721 – or change to NULL to prove query is functionally correct SET @sql = 'SELECT * FROM Sales.SalesOrderDetail WHERE 1 = 1' IF @id IS NOT NULL SET @sql = @sql + ' AND salesorderid = @id' IF @id IS NULL SET @sql = @sql + ' AND salesorderid IS NULL' SET @parameterlist = '@id INT' EXEC sp_executesql @sql, @parameterlist,@id Sometimes I think we focus too much on hardware and SQL Server configuration – when really the answer is focus on writing efficient SQL.

• Achieving decoupling in Model classes

  - by Guven

  I am trying to test-drive (or at least write unit tests) my Model classes but I noticed that my classes end up being too coupled. Since I can't break this coupling, writing unit tests is becoming harder and harder. To be more specific: Model Classes: These are the classes that hold the data in my application. They resemble pretty much the POJO (plain old Java objects), but they also have some methods. The application is not too big so I have around 15 model classes. Coupling: Just to give an example, think of a simple case of Order Header - Order Item. The header knows the item and the item knows the header (needs some information from the header for performing certain operations). Then, let's say there is the relationship between Order Item - Item Report. The item report needs the item as well. At this point, imagine writing tests for Item Report; you need have a Order Header to carry out the tests. This is a simple case with 3 classes; things get more complicated with more classes. I can come up with decoupled classes when I design algorithms, persistence layers, UI interactions, etc... but with model classes, I can't think of a way to separate them. They currently sit as one big chunk of classes that depend on each other. Here are some workarounds that I can think of: Data Generators: I have a package that generates sample data for my model classes. For example, the OrderHeaderGenerator class creates OrderHeaders with some basic data in it. I use the OrderHeaderGenerator from my ItemReport unit-tests so that I get an instance to OrderHeader class. The problem is these generators get complicated pretty fast and then I also need to test these generators; defeating the purpose a little bit. Interfaces instead of dependencies: I can come up with interfaces to get rid of the hard dependencies. For example, the OrderItem class would depend on the IOrderHeader interface. So, in my unit tests, I can easily mock the behaviour of an OrderHeader with a FakeOrderHeader class that implements the IOrderHeader interface. The problem with this approach is the complexity that the Model classes would end up having. Would you have other ideas on how to break this coupling in the model classes? Or, how to make it easier to unit-test the model classes?

• Modelling highly specific business requirements

  - by AndyBursh

  How can one go about modelling highly specific business requirements, which have no precedent in the system? Take for example the following requirement: When a purchase order contains N lines, is over X value in total and is being recorded against project Y, an email needs to be sent to persons A and B with the details This requirement supplements other requirements surrounding purchase orders, but comes in at a much later date in response to some ongoing problem elsewhere in the business. Persons A and B are not part of any role or group in the system, and don't hold any specific responsibility; they are simply the two people the business has appointed to receive these emails in this very specific case. Projects are also data driven, so project Y has no special properties to distinguish it from any other project. The only way to identify it is to compare its identifier to a magic number. How can one go about modelling this kind of case without introducing too much additional complexity? That I can think of right now, there are a couple of options. Perform the checks and actions inline with the existing code. Here we find the correct spot in the code, check the conditions in the requirement and send the emails to hardcoded addresses. Of course this is fraught with issues. At the very least it stops working if one of these people leaves or changes their email address. At worst you have to ensure that any tests and test data are aware that additional actions are taken for a specific set of criteria. Introduce some form of events system. Here we introduce an eventing system, so that we might react to some event, and fulfil the requirement outside of the usual path of execution. This sounds like a cleaner solution than option 1, but the work involved is ultimately probably slightly overkill for this one small requirement. That said, having it in place does allow the system to handle these kinds of specific requirements consistently and easily in the future. Are there any other (good/better) ways of handling highly specific requirements? I mean other than telling the other parts of the business no!

• Defining a service layer: the text-based adventure

  - by Stacy Vicknair

  Applications these days have more options than ever for a user interface, and it’s only going to grow. A successful product might require native applications for mobile devices, a regular web implementation, or even a gaming console. These systems often will be centralized and data driven. The solution is one that’s fairly solitary, a service layer! Simply put, take what’s shared and put it behind a physical or abstract layer that defines the boundary between the specific user interface and the shared content.   I know, I know, none of this is complicated. But some times it can be difficult to discern what belongs on which side of the line. For instance, say we’re creating a service that will provide content for both an ASP.NET MVC application and a WP7 application. Although the content served to each application is the same, there are different paradigms and patterns for displaying that data in the different environments. In ASP.NET MVC, you may create a model specific to a page that combines necessary information. In the WP7 application you might require different sets of data that you will connect via MVVM with the view. The general rule of thumb is that any shared content, business rules, or data should exist separately. Any element that is specific to the current UI implementation should be included in a separate library or with the UI implementation itself. The WP7 application doesn’t need my MVC specific model classes. My MVC application doesn’t require those INotifyPropertyChanged viewmodels that the WP7 application depends on. In both cases, there should be additional processing done above the service layer to massage the data to the application’s specific needs.   Service-ocalypse: the text based adventure What helps me the most about deciding whether or not something belongs coupled to the UI implementation or in the shared implementation is thinking of the simplest implementation you could have: a console application. You might have played a game like Peasant’s Quest: The console app is the text based adventure game version of your application. If you’re service was consumed in its simplest form, you would simply have a console based API for it that issues requests. Maybe those requests aren’t SWIM TO BOAT, but they might be CREATE USER JOHN. If I issue a request, I expect that request to be issued to the service. If the service has any exceptions or issues with my input, that business logic should be encapsulated in that service, not implemented in the UI. The service layer should be your functional application in its entirety, and anything above that layer should only assist with the display of that information.

• High CPU load for 1:30 minutes when mounting ext4-raid partition

  - by sirion

  I have a raid 5 (software) with 5x2TB drives. I encrypted the raid with cryptsetup and put an ext4-partition on top. In the beginning opening and mounting the raid took less than 10 seconds, now (for a few weeks) mounting alone takes 1:30 minutes and the cpu stays around 93% the whole time: The output of "time sudo mount /dev/mapper/8000 /media/8000" is: real 1m31.952s user 0m0.008s sys 1m25.229s At the same time only one line is added to /var/log/syslog: kernel: [ 2240.921381] EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null) My Ubuntu-version is "12.04.1 LTS" and no updates are pending. I checked the partition with fsck, but it says that all is ok. The "cryptsetup luksOpen" command only takes a few seconds. I also tried changing the raid-bitmap (as it was suggested in some forum) but it did not change the behaviour. sudo mdadm --grow /dev/md0 -b internal and sudo mdadm --grow /dev/md0 -b none I had the idea that it might be the hardware being slow, but a read test with "sudo hdparm -t /dev/md0" spit out values between 62 and 159 MB/sec: Timing buffered disk reads: 382 MB in 3.00 seconds = 127.14 MB/sec Timing buffered disk reads: 482 MB in 3.02 seconds = 159.62 MB/sec Timing buffered disk reads: 190 MB in 3.03 seconds = 62.65 MB/sec Timing buffered disk reads: 474 MB in 3.02 seconds = 157.12 MB/sec Although I think it is strange that the read rate jumps by more than 100% - could that mean something? The speed test when reading from the mapped (decrypted) device shows similar behavior, although it is of course much slower. "sudo hdparm -t /dev/mapper/8000": Timing buffered disk reads: 56 MB in 3.02 seconds = 18.54 MB/sec Timing buffered disk reads: 122 MB in 3.09 seconds = 39.43 MB/sec Timing buffered disk reads: 134 MB in 3.02 seconds = 44.35 MB/sec The output of a verbose mount "mount -vvv /dev/mapper/8000 /media/8000" does not help much: mount: fstab path: "/etc/fstab" mount: mtab path: "/etc/mtab" mount: lock path: "/etc/mtab~" mount: temp path: "/etc/mtab.tmp" mount: UID: 0 mount: eUID: 0 mount: spec: "/dev/mapper/8000" mount: node: "/media/8000" mount: types: "(null)" mount: opts: "(null)" mount: you didn't specify a filesystem type for /dev/mapper/8000 I will try type ext4 mount: mount(2) syscall: source: "/dev/mapper/8000", target: "/media/8000", filesystemtype: "ext4", mountflags: -1058209792, data: (null) Any idea where I could find additional information on why mounting takes so long, or what additional tests I could run?

• Multi-Part Map Troubleshooting

  - by Michael Stephenson

  Scenario I came across a nice little one with multi-part maps the other day. I had an orchestration where I needed to combine 4 input messages into one output message like in the below table:   Input Messages Output Messages Company Details Member Details Event Message Member Search Member Import   I thought my orchestration was working fine but for some reason when I was trying to send my message it had no content under the root node like below <ns0:ImportMemberChange xmlns:ns0="http://---------------/"></ns0:ImportMemberChange>   My map is displayed in the below picture. I knew that the member search message may not have any elements under it but its root element would always exist. The rest of the messages were expected to be fully populated. I tried a number of different things and testing my map outside of the orchestration it always worked fine. The Eureka Moment The eureka moment came when I was looking at the xslt produced by the map. Even though I'd tried swapping the order of the messages in the input of the map you can see in the below picture that the first part of the processing of the message (with the red circle around it) is doing a for-each over the GetCompanyDetailsResult element within the GetCompanyDetailsResponse message. This is because the processing is driven by the output message format and the first element to output is the OrganisationID which comes from the GetCompanyDetailsResponse message. At this point I could focus my attention on this message as the xslt shows that if this xpath statement doesn’t return the an element from the GetCompanyDetailsResponse message then the whole body of the output message will not be produced and the output from the map would look like the message I was getting. <ns0:ImportMemberChange xmlns:ns0="http://---------------/"></ns0:ImportMemberChange> I was quickly able to prove this in my map test which proved this was a likely candidate for the problem. I revisited the orchestration focusing on the creation of the GetCompanyDetailsResponse message and there was actually a bug in the orchestration which resulted in the message being incorrectly created, once this was fixed everything worked as expected. Conclusion Originally I thought it was a problem with the map itself, and looking online there wasn’t really much in the way of content around troubleshooting for multi-part map problems so I thought I'd write this up. I guess technically it isn't a multi-part map problem, but I spend a good couple of hours the other day thinking it was.

• Evolution laggy due to IMAP -profile or due to some odd Sync -issue?

  - by Izzy

  I'm fighting with Evolution. Basically it's working fine -- but it is very slow to react in certain situations. Helper questions Could it be that changing away from Bonobo has to do with slowing-down? There might be some trouble with the new engine and "asynchronous actions". What to do about it? Are there e.g. any configuration files? I want to get the previous "working mood" back. How can I speed this thing up? Different scenarios when sending a mail, the composer window hangs there inactive for a couple of seconds, everything grayed out. Though there is a green check mark saying it's sent, I'm not sure a) why it's still blocking everything and b) whether I could simply close it without "breaking"/"losing" anything. In earlier versions, the composer window was closing pretty fast, and one could see the message being stored into the local "outbox" until it was sent, and one could immediately continue with the next task. I prefer that behaviour over the current, where I cannot do anything in the application until the window closes. switching between modules. Coming from mail and switching to the address book takes a couple of seconds. Same for switching to the calendar. I read about different "possible causes" and tried a few things: I only have 3 local address books, so no networking should be involved here. To make sure, I switched to offline mode and then tried to access the address book. No noticeable difference. I use 3 Google Calendars. Switching to offline mode made a minor difference, but so minor that it also could be "imagination" since one might have expected this in this case according to some reports, disabling the tasks should help. Well, it didn't in my case, as I don't use them regularly (just two local items stored here) Maybe I should also mention that I'm using the KDE4 desktop (so no Unity or Gnome, though both is installed on the computer). And I did not have this issue before I updated to 12.04.

  Some background I work at a small startup: 4 devs, 1 designer, and 2 non-technical co-founders, one who provides funding, and the other who handles day-to-day management and sales. Our company produces mobile apps for target industries, and we've gotten a lot of lucky breaks lately. The outlook is good, and we're confident we can make this thing work. One reason is our product development team. Everyone on the team is passionate, driven, and has a great sense of what makes an awesome product. As a result, we've built some beautiful applications that we're all proud of. The other reason is the co-founders. Both have a brilliant business sense (one actually founded a multi-million dollar company already), and they have close ties in many of the industries we're trying to penetrate. Consequently, they've brought in some great business and continue to keep jobs in the pipeline. The problem The problem we can't seem to shake is how to bring these two awesome advantages together. On the business side, there is a huge pressure to deliver as fast as possible as much as possible, whereas on the development side there is pressure to take your time, come up with the right solution, and pay attention to all the details. Lately these two sides have been butting heads a lot. Developers are demanding quality while managers are demanding quantity. How can we handle this? Both sides are correct. We can't survive as a company if we build terrible applications, but we also can't survive if we don't sell enough. So how should we go about making compromises? Things we've done with little or no success: Work more (well, it did result in better quality and faster delivery, but the dev team has never been more stressed out before) Charge more (as a startup, we don't yet have the credibility to justify higher prices, so no one is willing to pay) Extend deadlines (if we charge the same, but take longer, we'll end up losing money) Things we've done with some success: Sacrifice pay to cut costs (everyone, from devs to management, is paid less than they could be making elsewhere. In return, however, we all have creative input and more flexibility and freedom, a typical startup trade off) Standardize project management (we recently started adhering to agile/scrum principles so we can base deadlines on actual velocity, not just arbitrary guesses) Hire more people (we used to have 2 developers and no designers, which really limited our bandwidth. However, as a startup we can only afford to hire a few extra people.) Is there anything we're missing or doing wrong? How is this handled at successful companies? Thanks in advance for any feedback :)

• Are You Meeting Social Customer Service Expectations?

  - by Mike Stiles

  Whether it’s B2B or B2C, one sure path to repeat business is making sure your buyer has a memorably pleasant and successful customer service experience with you. If they get that kind of treatment consistently, that’s called a relationship. And those aren’t broken easily. Social customer service, driven by integrated SRM (social relationship management) technology, is the venue that can effectively connect customers not only to the brand, but to other customers. Positive experiences, once administered, don’t just rest with the recipient. They’re published in the form of public raves and peer-to-peer recommendation, a force far more actionable than push advertising. What’s more, your customers have come to expect access to you and satisfaction from you using social. An NM Incite study shows 83% of Twitter users and 71% of Facebook users expect to get an answer from brands the same day they post to them on their social assets. To make sure you’re responding, you’ve got to have a tech platform that’s set up to moderate and alert so you’ll know ASAP a customer needs help. The more integrated your social enterprise is, the faster you can not only respond, but respond with the answer they’re looking for, because your system is connected to the internal resources that can surface the answer or put wheels in motion to rectify the situation in the shortest amount of time possible. But if you go to the necessary lengths to make sure your customers feel valued and important, will they really reward you? The study says 71% of consumers who got quick and effective responses from companies they contacted via social were more likely to recommend the brand to their friends and followers. So yes, sweeping people off their feet pays big dividends in terms of word-of-mouth marketing. But you should be keenly aware of the reverse side of that coin. Give people a negative experience, either in real world or virtual customer service, and that message is highly likely to get amplified through social channels faster and louder. Only 36% of the NM Incite study’s respondents reported that their problems were solved quickly and effectively. 36%? That’s hardly an impressive number. It gets worse. 10% never got so much as a response - at all. Going back to the relationship analogy, companies that are this deep in the ditch where customer service is concerned are making their girl or boyfriends really easy for a competitor to steal. Given the technology tools and data available right now for having an intimate knowledge of the customer, what products they’ve purchased, likely problems with those products, effective resolutions to those problems, and follow-up communication to gauge satisfaction, there are fewer excuses than ever for making the lifeblood of your business feel like you couldn’t care less. @mikestiles

• Taking a Projects Development to the Next Level

  - by user1745022

  I have been looking for some advice for a while on how to handle a project I am working on, but to no avail. I am pretty much on my fourth iteration of improving an "application" I am working on; the first two times were in Excel, the third Time in Access, and now in Visual Studio. The field is manufacturing. The basic idea is I am taking read-only data from a massive Sybase server, filtering it and creating much smaller tables in Access daily (using delete and append Queries) and then doing a bunch of stuff. More specifically, I use a series of queries to either combine data from multiple tables or group data in specific ways (aggregate functions), and then I place this data into a table (so I can sort and manipulate data using DAO.recordset and run multiple custom algorithms). This process is then repeated multiple times throughout the database until a set of relevant tables are created. Many times I will create a field in a query with a value such as 1.1 so that when I append it to a table I can store information in the field from the algorithms. So as the process continues the number of fields for the tables change. The overall application consists of 4 "back-end" databases linked together on a shared drive, with various output (either front-end access applications or Excel). So my question is is this how many data driven applications that solve problems essentially work? Each backend database is updated with fresh data daily and updating each takes around 10 seconds (for three) and 2 minutes(for 1). Project Objectives. I want/am moving to SQL Server soon. Front End will be a Web Application (I know basic web-development and like the administration flexibility) and visual-studio will be IDE with c#/.NET. Should these algorithms be run "inside the database," or using a series of C# functions on each server request. I know you're not supposed to store data in a database unless it is an actual data point, and in Access I have many columns that just hold calculations from algorithms in vba. The truth is, I have seen multiple professional Access applications, and have never seen one that has the complexity or does even close to what mine does (for better or worse). But I know some professional software applications are 1000 times better then mine. So Please Please Please give me a suggestion of some sort. I have been completely on my own and need some guidance on how to approach this project the right way.

• What ever happened to the Defense Software Reuse System (DSRS)?

  - by emddudley

  I've been reading some papers from the early 90s about a US Department of Defense software reuse initiative called the Defense Software Reuse System (DSRS). The most recent mention of it I could find was in a paper from 2000 - A Survey of Software Reuse Repositories Defense Software Repository System (DSRS) The DSRS is an automated repository for storing and retrieving Reusable Software Assets (RSAs) [14]. The DSRS software now manages inventories of reusable assets at seven software reuse support centers (SRSCs). The DSRS serves as a central collection point for quality RSAs, and facilitates software reuse by offering developers the opportunity to match their requirements with existing software products. DSRS accounts are available for Government employees and contractor personnel currently supporting Government projects... ...The DoD software community is trying to change its software engineering model from its current software cycle to a process-driven, domain-specific, architecture-based, repository-assisted way of constructing software [15]. In this changing environment, the DSRS has the highest potential to become the DoD standard reuse repository because it is the only existing deployed, operational repository with multiple interoperable locations across DoD. Seven DSRS locations support nearly 1,000 users and list nearly 9,000 reusable assets. The DISA DSRS alone lists 3,880 reusable assets and has 400 user accounts... The far-term strategy of the DSRS is to support a virtual repository. These interconnected repositories will provide the ability to locate and share reusable components across domains and among the services. An effective and evolving DSRS is a central requirement to the success of the DoD software reuse initiative. Evolving DoD repository requirements demand that DISA continue to have an operational DSRS site to support testing in an actual repository operation and to support DoD users. The classification process for the DSRS is a basic technology for providing customer support [16]. This process is the first step in making reusable assets available for implementing the functional and technical migration strategies. ... [14] DSRS - Defense Technology for Adaptable, Reliable Systems URL: http://ssed1.ims.disa.mil/srp/dsrspage.html [15] STARS - Software Technology for Adaptable, Reliable Systems URL: http://www.stars.ballston.paramax.com/index.html [16] D. E. Perry and S. S. Popovitch, “Inquire: Predicate-based use and reuse,'' in Proceedings of the 8th Knowledge-Based Software Engineering Conference, pp. 144-151, September 1993. ... Is DSRS dead, and were there any post-mortem reports on it? Are there other more-recent US government initiatives or reports on software reuse?

• A Simple Entity Tagger

  - by Elton Stoneman

  In the REST world, ETags are your gateway to performance boosts by letting clients cache responses. In the non-REST world, you may also want to add an ETag to an entity definition inside a traditional service contract – think of a scenario where a consumer persists its own representation of your entity, and wants to keep it in sync. Rather than load every entity by ID and check for changes, the consumer can send in a set of linked IDs and ETags, and you can return only the entities where the current ETag is different from the consumer’s version.  If your entity is a projection from various sources, you may not have a persistent ETag, so you need an efficient way to generate an ETag which is deterministic, so an entity with the same state always generates the same ETag. I have an implementation for a generic ETag generator on GitHub here: EntityTagger code sample. The essence is simple - we get the entity, serialize it and build a hash from the serialized value. Any changes to either the state or the structure of the entity will result in a different hash. To use it, just call SetETag, passing your populated object and a Func<> which acts as an accessor to the ETag property: EntityTagger.SetETag(user, x => x.ETag); The implementation is all in at 80 lines of code, which is all pretty straightforward: var eTagProperty = AsPropertyInfo(eTagPropertyAccessor); var originalETag = eTagProperty.GetValue(entity, null); try { ResetETag(entity, eTagPropertyAccessor); string json; var serializer = new DataContractJsonSerializer(entity.GetType()); using (var stream = new MemoryStream()) { serializer.WriteObject(stream, entity); json = Encoding.UTF8.GetString(stream.GetBuffer(), 0, (int)stream.Length); } var guid = GetDeterministicGuid(json); eTagProperty.SetValue(entity, guid.ToString(), null); //... There are a couple of helper methods to check if the object has changed since the ETag value was last set, and to reset the ETag. This implementation uses JSON to do the serializing rather than XML. Benefit - should be marginally more efficient as your hashing a much smaller serialized string; downside, JSON doesn't include namespaces or class names at the root level, so if you have two classes with the exact same structure but different names, then instances which have the same content will have the same ETag. You may want that behaviour, but change to use the XML DataContractSerializer if you think that will be an issue. If you can persist the ETag somewhere, it will save you server processing to load up the entity, but that will only apply to scenarios where you can reliably invalidate your ETag (e.g. if you control all the entry points where entity contents can be updated, then you can calculate and persist the new ETag with each update).

• Why do I have to divide the origin of a quad by 4 instead of 2?

  - by vinzBad

  I'm currently transitioning from C#/XNA to C#/OpenTK but I'm getting stuck at the basics. So I have this Sprite-Class: public static bool EnableDebugDraw = true; public float X; public float Y; public float OriginX = 0; public float OriginY = 0; public float Width = 0.1f; public float Height = 0.1f; public Color TintColor = Color.Red; float _layerDepth = 0f; public void Render() { Vector2[] corners = { new Vector2(X-OriginX,Y-OriginY), //top left new Vector2(X +Width -OriginX,Y-OriginY),//top right new Vector2(X +Width-OriginX,Y+Height-OriginY),//bottom rigth new Vector2(X-OriginX,Y+Height-OriginY)//bottom left }; GL.Color3(TintColor); GL.Begin(BeginMode.Quads); { for (int i = 0; i < 4; i++) GL.Vertex3(corners[i].X,corners[i].Y,_layerDepth); } GL.End(); if (EnableDebugDraw) { GL.Color3(Color.Violet); GL.PointSize(3); GL.Begin(BeginMode.Points); { for (int i = 0; i < 4; i++) GL.Vertex2(corners[i]); } GL.End(); GL.Color3(Color.Green); GL.Begin(BeginMode.Points); GL.Vertex2(X + OriginX, Y + OriginY); GL.End(); } With the following setup I try to set the origin of the quad to the middle of the quad. _sprite.OriginX = _sprite.Width / 2; _sprite.OriginY = _sprite.Height / 2; but this sets the origin to the upper right corner of the quad, so i have to _sprite.OriginX = _sprite.Width / 4; _sprite.OriginY = _sprite.Height / 4; However this is not the intended behaviour, could you advise me how I fix this?

• Strangling the life out of Software Testing

  - by MarkPearl

  I recently did a course at the local university on Software Engineering. At the beginning of the course I looked over the outline of the subject and there seemed to be some really good content. It covered traditional & agile project methodologies, some general communication and modelling chapters and finished off with testing. I was particularly excited to see the section on testing as this was something I learnt on my own and see great value in. The course has now just ended and I am very disappointed. I now know one of the reasons why so few people i.e. in my region do Test Driven Development, or perform even basic testing methodologies. The topic was to academic! Yes, you might be able to list 4 different types of black box test approaches vs. white box test approaches and describe the characteristics of Smoke Tests, but never during course did we see an example of an actual test or how it might be implemented! In fact, if I did not have personal experience of applying testing in actual projects, I wouldn’t even know what a unit test looked like. Now, what worries me is the following… It took us 6 months to cover the course material, other students more than likely came out of that course with little appreciation of the subject – in fact they now have a very complex view of what a test is – so complex that I think most of them will never attempt it again on their own. Secondly, imagine studying to be a dentist without ever actually seeing a tooth? Yes, you might be able to describe a tooth, and know what it is made out of – but nobody would want a dentist who has never seen a tooth to operate on them. Yet somehow we expect people studying software engineering to do the same? This is not right. Now, before I finish my rant let me say that I know this is not the same everywhere in the world, and that there needs to be a balance on practical implementation and academic understanding – I am just disappointed that this does not seem to be happening at the institution that I am currently studying at ;-( Please, if you happen to be a lecturer or teacher reading this post – a combination of theory and practical's goes a long way. We need to up the quality of software being produced and that starts at learner level!

• How do I server multiple domains from the same directory and codebase without my configuraton breaking when apache.conf is overwritten?

  - by neokio

  I have 20 domains on a VPS running cPanel. One public_html is filled with code, the remaining 19 are symbolic links to that one. (For example, assets is a directory within public_html ... for the 19 others, there's a symbolic link to that directory in each each accounts public_html dir.) It's all PHP / MySQL database driven, with content changing depending on the domain. It works like a charm, assuming cPanel has suExec enabled correctly, and assuming apache.conf does NOT have SymLinksIfOwnerMatch enabled. However, every few weeks, my apache.conf is mysteriously overwritten, re-enabling SymLinksIfOwnerMatch, and disabling all 19 linked sites for as long as it takes for me to notice. Here's the offending line in apache.conf: <Directory "/"> AllowOverride All Options ExecCGI FollowSymLinks IncludesNOEXEC Indexes SymLinksIfOwnerMatch </Directory> The addition of SymLinksIfOwnerMatch disables the sites in a strange way ... the html is generated correctly, but all css/js/image in the html fails to load. Clicking any link redirects to /. And I have no idea why. I do have a few things in my .htaccess, which work fine when SymLinksIfOwnerMatch is not present: <IfModule mod_rewrite.c> # www.example.com -> example.com RewriteCond %{HTTPS} !=on RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC] RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L] # Remove query strings from static resources RewriteRule ^assets/js/(.*)_v(.*)\.js /assets/js/$1.js [L] RewriteRule ^assets/css/(.*)_v(.*)\.css /assets/css/$1.css [L] RewriteRule ^assets/sites/(.*)/(.*)_v(.*)\.css /assets/sites/$1/$2.css [L] # Block access to hidden files and directories RewriteCond %{SCRIPT_FILENAME} -d [OR] RewriteCond %{SCRIPT_FILENAME} -f RewriteRule "(^|/)\." - [F] # SLIR ... reroute images to image processor RewriteCond %{REQUEST_URI} ^/images/.*$ RewriteRule ^.*$ - [L] # ignore rules if URL is a file RewriteCond %{REQUEST_FILENAME} !-f # ignore rules if URL is not php #RewriteCond %{REQUEST_URI} !\.php$ # catch-all for routing RewriteRule . index.php [L] </ifModule> I also use most of the 5G Blacklist 2013 for protection against exploits and other depravities. Again, all of this works great, except when SymLinksIfOwnerMatch gets added back into apache.conf. Since I've failed to find the cause of whatever cPanel/security update is overwriting apache.conf, I thought there might be a more correct way to accomplish my goal using group permissions. I've created a 'www' group, added all accounts to the group, and chmod -R'd the code source to use that group. Everything is 644 or 755. But doesn't seem to be enough. My unix isn't that strong. Do you need to restart something for group changes to take effect? Probably not. Anyways, I'm entering unknown territory. Can anyone recommend the right way to configure a website for multiple sites using one codebase that doesn't rely on apache.conf?

• Should I use my own public API on my site (via JS)?

  - by newboyhun

  First of all, this question is far more different other 'public api questions' like this: Should a website use its own public API?, second, sorry for my English. You can find the question summarized at the bottom of this question. What I want to achieve is a big website with a public api, so who like programming (like me) and likes my website, can replicate my website's data with a much better approach (of course with some restrictions). Almost everything could be used by the public API. Because of this, I was thinking about making the whole website AJAX driven. There would be parts of the API which would be limited only to my website (domain), like login, registering. There would be only an INTERFACE on the client side, which would use the public and private API to make this interface working. The website would be ONLY CLIENT SIDE, well, I mean, the website would only use AJAX to use the api. How do I imagine this? The website would be like a mobile application, the application only sending a request to a webserver, which returns a json, the application parses it, and uses it to advance in the application. (e.g.: login) My thoughts: Pros: The whole website is built up by javascript, this means I don't need to transfer the html to the client, saving bandwidth. (I hope so) Anyone can use up the data of my website to make their own cool things. (Is this a con or pro? O_O) The public API is always in use, so I can see if there are any error. Cons: Without Javascript the website is unusable. The bad guys easily can load the server with requesting too much data (like Request Per Second 10000), but this can be countered via limiting this with some PHP code and logging. Probably much more work So the question in some words is: Should I build my website around my own api? Is it good to work only on the client side? Is this good for a big website? (e.x.: facebook, yeah facebook is a different story, but could it run with an 'architecture' like this?)

• Application stuck in TCP retransmit

  - by SandeepJ

  I am running Linux kernel 3.13 (Ubuntu 14.04) on two Virtual Machines each of which operates inside two different servers running ESXi 5.1. There is a zeromq client-server application running between the two VMs. After running for about 10-30 minutes, this application consistently hangs due to inability to retransmit a lost packet. When I run the same setup over Ubuntu 12.04 (Linux 3.11), the application never fails If you notice below, "ss" (socket statistics) shows 1 packet lost, sk_wmem_queued of 14110 (i.e. w14110) and a high rto (120000). State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 12350 192.168.2.122:41808 192.168.2.172:55550 timer:(on,16sec,10) uid:1000 ino:35042 sk:ffff880035bcb100 <- skmem:(r0,rb648720,t0,tb1164800,f2274,w14110,o0,bl0) ts sack cubic wscale:7,7 rto:120000 rtt:7.5/3 ato:40 mss:8948 cwnd:1 ssthresh:21 send 9.5Mbps unacked:1 retrans:1/10 lost:1 rcv_rtt:1476 rcv_space:37621 Since this has happened so consistently, I was able to capture the TCP log in wireshark. I found that the packet which is lost does get retransmitted and even acknowledged by the TCP in the other OS (the sequence number is seen in the ACK), but the sender doesn't seem to understand this ACK and continues retransmitting. MTU is 9000 on both virtual machines and througout the route. The packets being sent are large in size. As I said earlier, this does not happen on Ubuntu 12.04 (kernel 3.11). So I did a diff on the TCP config options (seen via "sysctl -a |grep tcp ") between 14.04 and 12.04 and found the following differences. I also noticed that net.ipv4.tcp_mtu_probing=0 in both configurations. Left side is 3.11, right side is 3.13 <<net.ipv4.tcp_abc = 0 <<net.ipv4.tcp_cookie_size = 0 <<net.ipv4.tcp_dma_copybreak = 4096 14c11 << net.ipv4.tcp_early_retrans = 2 --- >> net.ipv4.tcp_early_retrans = 3 17c14 << net.ipv4.tcp_fastopen = 0 >> net.ipv4.tcp_fastopen = 1 20d16 << net.ipv4.tcp_frto_response = 0 26,27c22 << net.ipv4.tcp_max_orphans = 16384 << net.ipv4.tcp_max_ssthresh = 0 >> net.ipv4.tcp_max_orphans = 4096 29,30c24,25 << net.ipv4.tcp_max_tw_buckets = 16384 << net.ipv4.tcp_mem = 94377 125837 188754 >> net.ipv4.tcp_max_tw_buckets = 4096 >> net.ipv4.tcp_mem = 23352 31138 46704 34a30 >> net.ipv4.tcp_notsent_lowat = -1 My question to the networking experts on this forum : Are there any other debugging tools or options I can install/enable to dig further into why this TCP retransmit failure is occurring so consistently ? Are there any configuration changes which might account for this weird behaviour.

• SD Card reader not working on Sony Vaio

  - by TessellatingHeckler

  This laptop (Sony Vaio VGN-Z31MN/B PCG-6z2m) has been installed with Windows 7 64 bit, all the drivers from Sony's VAIO site are installed, and everything in Device Manager both (a) has a driver and (b) shows as working, no exclamation marks or warnings. "Hide empty drives" in Folder options is disabled so the card reader appears, but will not read the card ("please insert a disk in drive O:"). Previously, when the laptop had Windows XP on it, it could read the same card. Also, Windows update suggested driver ("SD Card Reader") doesn't work, Ricoh own drivers install properly but do the same behaviour. Other 3rd party driver suggestions from forums (Acer and Texas-Instruments FlashMedia) do not seem to install properly. I would post the PCI id if I had it, but it was just showing up as rimsptsk\diskricohmemorystickstorage (while it had the Ricoh Driver installed). Edit: If there are any lower level diagnostic utlities which might shed more light on it I'd welcome hearing of them. Anything which might show get it to put troubleshooting logs in the event log or identify chipsets or whatever...

• AWS Cloud Formation.Requires capabilities : [CAPABILITY_IAM] (Child Stack)

  - by Drew Khoury

  I'm running a CloudFormation template in the AWS Console. Running Stack Directly I started with a template that used IAM resources, and the console prompts me to acknowledge IAM capabilities when running the stack directly. Running Stack as a child I then tried to call the same stack from a parent stack and did not receive the same prompt. The stack then failed with the message: Requires capabilities : [CAPABILITY_IAM] Research The docs indicate that I can run CF scripts in a number of ways. There's plenty of docs around CLI/API and supplying the capability parameter, but there appears to be no information about how to make sure it's applied when running through the console. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html IAM Resources in AWS CloudFormation Templates CF Console CLI API What I've done / What I think I've raised an issue via the forum for now, but no response (yet): https://forums.aws.amazon.com/thread.jspa?threadID=139160 I suspect this is a bug in the Console, as there doesn't appear to be any documentation of how to change the behaviour via the console and as far as I'm aware this should just work. Anyone came across the same problem, or can report that it's working fine for them?

• MultiView 2000 terminal emulator not printing correctly to Generic/Text Printer on Windows 7

  - by FantaFan

  Guys & gals, Hope someone can shed some light on this. I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck. As you might expect, it does work fine in XP Mode (as long as I print to a printer defined therein and not the host's printer) but operationally this isn't going to be an option. Obviously this emulation software is a decade old (at least) and I could just cross/upgrade all the users (at a cost) but, before I do so, has anyone seen this sort of behaviour before and found some sort of fix? Remote OS: AIX 5 Client OS: Windows 7 Pro (32-bit) Printer: Generic/Text on a FILE port TE Software: MultiView 2000 (320-bit) Thanks in advance.

I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck. As you might expect, it does work fine in XP Mode (as long as I print to a printer defined therein and not the host's printer) but operationally this isn't going to be an option. Obviously this emulation software is a decade old (at least) and I could just cross/upgrade all the users (at a cost) but, before I do so, has anyone seen this sort of behaviour before and found some sort of fix? Remote OS: AIX 5 Client OS: Windows 7 Pro (32-bit) Printer: Generic/Text on a FILE port TE Software: MultiView 2000 (32-bit) Thanks in advance.
