• SQL SERVER – A Cool Trick – Restoring the Default SQL Server Management Studio – SSMS

  - by pinaldave

  “I do not know where my windows went!” “I just closed my object explorer and now I cannot find it.” “How do I get my original windows layout back in SQL Server Management Studio?” “How do I get the window which was there in left side back again?” Since last 2-3 years, every single day I receive more than 5 emails on SSMS and its layout. For the beginners it is very common to get confused when they attempt to change SQL Server Management Studio’s windows layout. They often change the layout and are not able to get the original layout back. Often people do not change the layout whole of their life, leading to uncomfortable feeling when they go to another’s computer where the windows are differently placed. Today’s blog post is dedicated all the beginners in SQL Server. It is extremely simple to reset the SSMS layout to default layout. The default layout involves 2 major things 1) Object Explorer on left side 2) Query Windows on right side (80% screen estate). Personally I am so used to this as well that if there is any other changes in the same, I do not enjoy working on the environment. Well, the solution to rest the SSMS layout is very simple. One can do it in split seconds.  To restore the default configuration, on the Window menu, click Reset Window Layout. Have you ever used this feature? Do you feel uncomfortable when SSMS layout is not in default state? How do you address this situation?

• Configuring LiveID authentication with SharePoint2010

  - by ybbest

  With the addition of the new claims based authentication framework in SharePoint 2010, SharePoint is now more loosely coupled to the authentication layer than ever. You’ve probably seen presentations or webinars where it was mentioned that you can use claims authentication against authentication providers such as Live ID and OpenID. In this blog I will show you the common problems while you configure you LiveID integration with SharePoint2010.The detailed configuration can be found in the following blogs. Part 1 – http://www.wictorwilen.se/Post/Visual-guide-to-Windows-Live-ID-authentication-with-SharePoint-2010-part-1.aspx Part 2 – http://www.wictorwilen.se/Post/Visual-guide-to-Windows-Live-ID-authentication-with-SharePoint-2010-part-2.aspx Part 3 – http://www.wictorwilen.se/Post/Visual-guide-to-Windows-Live-ID-authentication-with-SharePoint-2010-part-3.aspx Here are some problems I have following the instructions: Problem 1: If you had the following exceptions when you run the PowerShell scripts to create the new LiveID authentication provider New-SPTrustedIdentityTokenIssuer : Exception of type ‘System.ArgumentException’ was thrown.Parameter name: claimType At line:1 char:42 + $authp = New-SPTrustedIdentityTokenIssuer <<<< -Name “LiveID INT” -Description “LiveID INT” -Realm $realm -ImportTrustCertificate $certfile -ClaimsMappings $emailclaim,$upnclaim -SignInUrl “https://login.live-int.com/login.srf” -IdentifierClaim $emailclaim.InputClaimType + CategoryInfo : InvalidData:(Microsoft.Share…dentityProvider:SPCmdletNewSPIdentityProvider) [New-SPTrustedIdentityTokenIssuer], ArgumentException + FullyQualifiedErrorId :Microsoft.SharePoint.PowerShell.SPCmdletNewSPIdentityProvider Solution: You need to Remove the existing the SPTrustedIdentityTokenIssuer.     1. You need to first get the existing TokenIssuer name by Get-SPTrustedIdentityTokenIssuer, and then run Remove- SPTrustedIdentityTokenIssuer to remove the existing TokenIssuer.     2. After that , you can re-run the script , everything should work fine now. Problem 2: Live INT automatically logs out Whenever I try to log in (https://login.live-int.com/login.srf), after entering valid email/password I get redirected to the logout page. Solution: You can find the solution in my previous blog.

• How to handle growing QA reporting requirements?

  - by Phillip Jackson

  Some Background: Our company is growing very quickly - in 3 years we've tripled in size and there are no signs of stopping any time soon. Our marketing department has expanded and our IT requirements have as well. When I first arrived everything was managed in Dreamweaver and Excel spreadsheets and we've worked hard to implement bug tracking, version control, continuous integration, and multi-stage deployment. It's been a long hard road, and now we need to get more organized. The Problem at Hand: Management would like to track, per-developer, who is generating the most issues at the QA stage (post unit testing, regression, and post-production issues specifically). This becomes a fine balance because many issues can't be reported granularly (e.g. per-url or per-"page") but yet that's how Management would like reporting to be broken down. Further, severity has to be taken into account. We have drafted standards for each of these areas specific to our environment. Developers don't want to be nicked for 100+ instances of an issue if it was a problem with an include or inheritance... I had a suggestion to "score" bugs based on severity... but nobody likes that. We can't enter issues for every individual module affected by a global issue. [UPDATED] The Actual Questions: How do medium sized businesses and code shops handle bug tracking, reporting, and providing useful metrics to management? What kinds of KPIs are better metrics for employee performance? What is the most common way to provide per-developer reporting as far as time-to-close, reopens, etc.? Do large enterprises ignore the efforts of the individuals and rather focus on the team? Some other questions: Is this too granular of reporting? Is this considered 'blame culture'? If you were the developer working in this environment, what would you define as a measureable goal for this year to track your progress, with the reward of achieving the goal a bonus?

• 2D graphics - why use spritesheets?

  - by Columbo

  I have seen many examples of how to render sprites from a spritesheet but I havent grasped why it is the most common way of dealing with sprites in 2d games. I have started out with 2d sprite rendering in the few demo applications I've made by dealing with each animation frame for any given sprite type as its own texture - and this collection of textures is stored in a dictionary. This seems to work for me, and suits my workflow pretty well, as I tend to make my animations as gif/mng files and then extract the frames to individual pngs. Is there a noticeable performance advantage to rendering from a single sheet rather than from individual textures? With modern hardware that is capable of drawing millions of polygons to the screen a hundred times a second, does it even matter for my 2d games which just deal with a few dozen 50x100px rectangles? The implementation details of loading a texture into graphics memory and displaying it in XNA seems pretty abstracted. All I know is that textures are bound to the graphics device when they are loaded, then during the game loop, the textures get rendered in batches. So it's not clear to me whether my choice affects performance. I suspect that there are some very good reasons most 2d game developers seem to be using them, I just don't understand why.

• DNS hijack - prevention tips

  - by user578359

  Hi there, Over the weekend it looks like the DNS was hijacked on two of my domains. My set up is I have the sites registered on 1and1.co.uk, with dns nameservers pointing to Hostgator in the US where the sites are hosted. I also had cloudflare CDN running on the sites (via hostgator cpanel). My question is any ideas as to how this happened, and how I could either monitor it so I know if it occurs again, or strengthen the set up/service to minimise the risk. History: I received a ping from my site monitoring service that the sites were down. When I checked the sites were up so I assumed it was local to the monitoring service I received a ping last night the sites were up When I checked, one site was redirecting to download-manual.com (and checking that URL now, the home page is not the same as the one I saw, so they too may have been hijacked/hacked) The other site URL remained the same but had one of those standard site search pages which bounce you off to either phishing or paid for search sites I notified Hostgator who told me Cloudflare or 1and1 were the issue. I removed cloudflare, and contacted both them and hostgator, and am awaiting a response, but am not holding my breath. Is this common? I've never heard of this or come across this before. It's pretty scary that this can happen so easily. Appreciate any input. **Update: I've now spoken to support at 1and1, Hostgator, and Cloudflare, and each one claims it has nothing to do with them, and must be one of the others. Larry, curly, moe.

• WPF and Composite Application Library &ndash; Missing The Point

  - by David Totzke

  I have a headache and it’s not even 9AM yet.  Well, ok, it’s nearly ten here now in GMT –5 but it’s before nine somewhere still. Sometimes people will miss the point of something so utterly and completely that one is left wondering how such a person can even dress themselves. Writing an application using WPF and the Composite Application Library (Prism) means that one must learn the various programming idioms common to these frameworks.  The Windows Forms event driven model simply will not suffice.  You need to come to grips with the idea of a very loosely coupled application.  Concepts that must be absorbed and internalized include Data Binding, Control and Data Templates, Commands, Dependency Injection, and Inversion of Control, as well as the Supervising Controller, Presentation Model and Model-View-View-Model patterns. It is as simple as that.  Not to embrace these concepts is to invite pain.  It is to invite noodles; and not the holy kind. Someone actually said to me that “just because it’s not WPF, doesn’t mean it’s wrong.”  And he’s right.  Unless, of course, you are writing a WPF application and especially if you are using the Composite Application Library. In simple terms then; YOU’RE DOING IT WRONG!   Dave Just because I can…

• .wine-pipelight folder not present

  - by DaimyoKirby

  Following the instructions on the pipelight installation page, I installed pipelight on Ubuntu 14.04. However, upon opening firefox the .wine-pipelight folder isn't present in my home folder, and I get the following errors: [PIPELIGHT:LIN:unknown] attached to process. [PIPELIGHT:LIN:unknown] checking environment variable PIPELIGHT_SILVERLIGHT5_1_CONFIG. [PIPELIGHT:LIN:unknown] searching for config file pipelight-silverlight5.1.

I've reinstalled quite a few times and ran through many of the common fixes offered on the pipelight Launchpad pages and here on AskUbunta and still it fails to run. Is there a reason why this folder isn't present, or why I'm getting these errors? Edit: Oddly enough, the .wine-pipelight folder is created wtih I open Nitro, although this still doesn't fix the issue.

• SSMS Tools Pack 2.0 is out! With huge productivity booster features that will blow your mind and ease your job even more.

  - by Mladen Prajdic

  What better way to end the summer and start those productive autumn days ahead than with a fresh new version of the SSMS Tools Pack. This is a big release with two new features that are huge productivity boosters. First new feature are Tab Sessions. Every SQL tab you open is saved every N (default 2) minutes and is stored in a session. This works similar to internet browser sessions. Once you reopen SSMS you can restores your last session with a click of a button. You even get every window connected to the server it was previously connected to. The Tab History Window looks like this:   The second feature is Execution Plan Analyzer. It is designed to quickly help you find costliest operators by a number of properties. If that's not enough you can easily search through the whole execution plan for whatever you like. And to top it off you can auto analyze the execution plan. The analysis reports various problems the execution plan has and suggests a most common solution. The ultimate purpose of the Execution Plan Analyzer is to make your troubleshooting quicker and easier. It uses a simple user interface that is easy to navigate and is built directly into the execution plan itself. The execution plan analyzer looks like this:   Smaller fixes include a completely redesigned SQL History Search window and various other bug fixes. You can download the new version 2.0 at the Download page. For more detailed feature descriptions go to the main Features Page. Enjoy it!

• Try out ubuntu on thinkpad x40 (via usb)?

  - by Oliver

  I am trying to try out ubuntu (i,e, install it within windows) on my thinkpad x40. I followed the instructions on how to create a bootable usb (http://www.ubuntu.com/download/ubuntu/download). No problem. The issue I have now is that th eusb ports on my x40 were burned before (common problem with the machine), i.e. do not work. So I got a USB notebook card from belkin. However it does not seem to recognize the usb stick from bios, thus I cannot boot from it. I also do not have a cd rom. Then tried to run wubi from the usb stick, briefly appears in task manager, no further action. So I tried it with wubi.exe, but same thing. Downloaded it to desktop, run it, briefly appears in the task manager under processes, no further action. Any one idea? I have enough memory and enough freed hd space. Thanks. Oliver

• How to refactor while keeping accuracy and redundancy?

  - by jluzwick

  Before I ask this question I will preface it with our environment. My team consists of 3 programmers working on multiple different projects. Due to this, our use of testing is mostly limited to very general black box testing. Take the following assumptions also: Unit Tests will eventually be written but I'm under strict orders to refactor first Ignore common Test-Driven Development techniques when given this environment, my time is limited. I understand that if this were done correctly, our team would actually save money in the long-term by building Unit-Tests before hand. I'm about to refactor a fairly large portion of the code that is critical. While I believe my code will accurately work when done and after our black box testing, I realize that there will be new data that the new code might not be able to handle. What I wanted to know is how to keep old code that functions 98% of the time so that we can call those subroutines in case the new code doesn't work properly. Right now I'm thinking of separating the old code in a separate class file and adding a variable to our config that will tell the program which code to use. Is there a better way to handle this? NOTE: We do use revision control and we have archived builds so the client could always revert to a previous build, but I would like to see if there is a decent way of doing this besides reverting. I want this so they can use the other new functionality delivered in the new build. Edit: While I agree I will need to write Unit Tests for this, I don't believe I will capture everything with them. I'm looking for ways to easily be able to revert to the old, functional code should anything happen. While I know this is a poor practice, I'm planning on removing this code after our team can guarantee that the new code works to the same standards as the old.

• DIY Carbonator Creates Pop Rocks Like Fizzy Fruit [Science]

  - by Jason Fitzpatrick

  If you’ve ever sat around wishing that scientists would stop wasting time trying to solve pressing global problems and instead genetically engineer a bizarre but delicious hybrid of Pop Rocks candy and wholesome fruit, this mad scientist experiment is for you. Over at Evil Mad Scientist Laboratories they share a really fun weekend project. Contributor Rich Faulhaber was looking for a way to make eating fruit extra fun and science-infused for his kids. His solution? Build a homemade carbon dioxide injector that infuses fruit with carbonation. Having trouble imagining that? Envision a bowl of strawberries where every strawberry burst into a crazy flurry of strawberry flavor and champagne bubbles every time you bit into it. Fizzy fruit! Hit up the link below to see how he took pretty common parts: a C02 tank from a paint ball gun, a water filter canister from the hardware store, and other cheap and readily available parts (with the exception of the gas regulator which he suggests you shop garage sales and surplus stores to find a deal on), and combined them together to create a C02 fruit infuser.

• SQL SERVER – Load Generator – Free Tool From CodePlex

  - by pinaldave

  One of the most common questions I receive is if there any tool available to generate load on SQL Server. Absolutely there is a fabulous free tool available to generate load on SQL Server on Codeplex. This tool was released in 2008 but it is still extremely relevant to generate the load on SQL Server as well works fabulously. CodePlex is a project initiated by Microsoft for hosting open source softwares. The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. One of the things which I felt needed improvement was a default configuration. As every single time when I was adding a query the default settings were showing up and I had to manually change that. However, when I went to Menu >> Tools >>Options I was really happy as it has options to change every single default which is available. Here one can give default username, password, database name as well various settings related to configuration. Additionally application logging is also possible through the options. A couple of other important points I noticed was the button to reset counters as well status bar containing useful information of Total Threads, Completed Queries and Failed Queries. I use this frequently for my load testing. What tool do you use for SQL Server Load Generator?

• Is shipping a Clojure desktop app realistic?

  - by Cedric Martin

  I'm currently shipping a desktop Java application. It is a plain old Java 5 Java / Swing app and so far everything worked nicely. Java 5 was targetted because some users were on OS X version / computers that shall never have Java 6 (we may lift this limitation soon and switch to a newer Java and simply abandoning my users stuck with Java 5). I'm quickly getting up to speed with Clojure but I haven't really done lots of Clojure-to-Java and Java-to-Clojure yet and I was wondering if it was realistic to ship a Clojure desktop application instead of a Java application? The application I'm shipping is currently about 12 MB with all the .jar so adding Clojure doesn't seen to be too much of an issue. My plan would be to have Clojure call Java APIs: my application is already divided in several independent jars. If I understand correctly calling Clojure from Java is harder than calling Java code from Clojure which is why I'd basically rewrite all the UI (part of the UI, mixing Swing components and self-made BufferedImages needs to be rewritten anyway due to the rise of retina display), and do all the 'wiring' from Clojure. So that's the problem I'm facing: is it realistic to ship a Clojure desktop app? (it certainly doesn't seem to be very widespread but then shipping plain Java desktop apps ain't that common either and I'm doing it anyway) Technically, what would need to be done? (compared to shipping a Java app)

• Designing configuration for subobjects

  - by Stefano Borini

  I have the following situation: I have a class (let's call it Main) encapsulating a complex process. This class in turn orchestrates a sequence of subalgorithms (AlgoA, AlgoB), each one represented by an individual class. To configure Main, I have a configuration stored into a configuration object MainConfig. This object contains all the config information for AlgoA and AlgoB with their specific parameters. AlgoA has no interest to the information relative to the configuration of AlgoB, so technically I could have (and in practice I have) a contained MainConfig.AlgoAConfig and MainConfig.AlgoBConfig instances, and initialize as AlgoA(MainConfig.AlgoAConfig) and AlgoB(MainConfig.AlgoBConfig). The problem is that there is some common configuration data. One example is the printLevel. I currently have MainConfig.printLevel. I need to propagate this information to both AlgoA and AlgoB, because they have to know how much to print. MainConfig also needs to know how much to print. So the solutions available are I pass the MainConfig to AlgoA and AlgoB. This way, AlgoA has technically access to the whole configuration (even that of AlgoB) and is less self-contained I copy the MainConfig.printLevel into AlgoAConfig and AlgoBConfig, so I basically have three printLevel information repeated. I create a third configuration class PrintingConfig. I have an instance variable MainConfig.printingConfig, and then pass to AlgoA both MainConfig.AlgoAConfig and MainConfig.printingConfig. Have you ever found this situation? How did you solve it ? Which one is stylistically clearer to a new reader of the code ?

• Where should SQL/DB Queries be encapsulated in a software system?

  - by Stephen Bennet

  I frequently write small applications (either web based or otherwise) that require heavy database usage. i've attempted various ways of handling where to put the actual sql queries (sort of ad-hoc ORM systems). These include: Models that build themselves up - and only allowing SQL to be inside of a model. A sort of factory style method where the models are built by a factory class that is allowed to know about SQL. A third entity that maps models based on their fields/keys into the database and generates SQL code on the fly based on this. Is there a common knowledge of which method is best? Or another way I have missed? Clearly a lot of it will be based on the context of the system itself, which for me is usually to produce lightweight tools or utility frameworks. In experimenting, I've never found any of them that feel intuitively "right" and not clunky, but I also do not want to go for a full framework such as Django or Ruby - both because the tools I create are in a variety of languages and because they usually do not warrant that level of surrounding footprint.

• XNA Seeing through heightmap problem

  - by Jesse Emond

  I've recently started learning how to program in 3D with XNA and I've been trying to implement a Terrain3D class(a very simple height map). I've managed to draw a simple terrain, but I'm getting a weird bug where I can see through the terrain. This bug happens when I'm looking through a hill from the map. Here is a picture of what happens: I was wondering if this is a common mistake for starters and if any of you ever experienced the same problem and could tell me what I'm doing wrong. If it's not such an obvious problem, here is my Draw method: public override void Draw() { Parent.Engine.SpriteBatch.Begin(SpriteBlendMode.None, SpriteSortMode.Immediate, SaveStateMode.SaveState); Camera3D cam = (Camera3D)Parent.Engine.Services.GetService(typeof(Camera3D)); if (cam == null) throw new Exception("Camera3D couldn't be found. Drawing a 3D terrain requires a 3D camera."); float triangleCount = indices.Length / 3f; basicEffect.Begin(); basicEffect.World = worldMatrix; basicEffect.View = cam.ViewMatrix; basicEffect.Projection = cam.ProjectionMatrix; basicEffect.VertexColorEnabled = true; Parent.Engine.GraphicsDevice.VertexDeclaration = new VertexDeclaration( Parent.Engine.GraphicsDevice, VertexPositionColor.VertexElements); foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Begin(); Parent.Engine.GraphicsDevice.Vertices[0].SetSource(vertexBuffer, 0, VertexPositionColor.SizeInBytes); Parent.Engine.GraphicsDevice.Indices = indexBuffer; Parent.Engine.GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, vertices.Length, 0, (int)triangleCount); pass.End(); } basicEffect.End(); Parent.Engine.SpriteBatch.End(); } Parent is just a property holding the screen that the component belongs to. Engine is a property of that parent screen holding the engine that it belongs to. If I should post more code(like the initialization code), then just leave a comment and I will.

• What Should You Look for In a CRM Demo?

  - by charles.knapp

  I have helped firms evaluate software demos and delivered demos in diverse industries such as manufacturing, healthcare, life sciences, and travel (to name just a few). Here are a few suggestions. First, which vendor has the best fit for your industry? Make sure that the vendor demo staff tell you clearly throughout the demo (not just in a passing comment), what portion of each business process and screen is standard, what has been configured, what has been custom coded, and what has been provided by a partner. If you don't keep asking, what you buy may be less useful than what you saw. This will lead to added (and unbudgeted) costs and time. Second, what are the roles of the primary users? What are their top-most needs, such as exception-oriented dashboards or rapid data entry? Can you get a demo for each key role, showing how the software fits a typical workday? Have the vendor repeatedly tell you what is standard, configured, custom coded, or provided by a partner. Third, how well does the demo balance ease of use with completeness of business processes? One common approach is to hide needed fields or steps that are of low visual value. Another approach is to focus heavily on a visually appealing capability, while downplaying the fit with your key business processes. Result: despite their business acumen, demo attendees may not focus adequately on gaps in business fit So, look for complete disclosure and complete CRM.

• Extreme Optimization –Mathematical Constants and Basic Functions

  - by JoshReuben

  Machine constants The MachineConstants class - contains constants for floating-point arithmetic because the CLS System.Single and Double floating-point types do not follow the standard conventions and are useless. machine constants for the Double type: machine precision: Epsilon , SqrtEpsilon CubeRootEpsilon largest possible value: MaxDouble , SqrtMaxDouble, LogMaxDouble smallest Double-precision floating point number that is greater than zero: MinDouble , SqrtMinDouble , LogMinDouble A similar set of constants is available for the Single Datatype  Mathematical Constants The Constants class contains static fields for many mathematical constants and common expressions involving small integers – if you are doing thousands of iterations, you wouldn't want to calculate OneOverSqrtTwoPi , Sqrt17 or Log17 !!! Fundamental constants E - The base for the natural logarithm, e (2.718...). EulersConstant - (0.577...). GoldenRatio - (1.618...). Pi - the ratio between the circumference and the diameter of a circle (3.1415...). Expressions involving fundamental constants: TwoPi, PiOverTwo, PiOverFour, LogTwoPi, PiSquared, SqrPi, SqrtTwoPi, OneOverSqrtPi, OneOverSqrtTwoPi Square roots of small integers: Sqrt2, Sqrt3, Sqrt5, Sqrt7, Sqrt17 Logarithms of small integers: Log2, Log3, Log10, Log17, InvLog10  Elementary Functions The IterativeAlgorithm<T> class in the Extreme.Mathematics namespace defines many elementary functions that are missing from System.Math. Hyperbolic Trig Functions: Cosh, Coth, Csch, Sinh, Sech, Tanh Inverse Hyperbolic Trig Functions: Acosh, Acoth, Acsch, Asinh, Asech, Atanh Exponential, Logarithmic and Miscellaneous Functions: ExpMinus1 - The exponential function minus one, ex-1. Hypot - The hypotenuse of a right-angled triangle with specified sides. LambertW - Lambert's W function, the (real) solution W of x=WeW. Log1PlusX - The natural logarithm of 1+x. Pow - A number raised to an integer power.

• 2 year degree plus experience vs 4 year degree

  - by CenterOrbit

  Alright, I have searched around a bit on this site and found two somewhat similar questions: Computer Science Programming Certificate vs. Computer Science Degree? Is it possible/likely to be paid fairly without a college degree? But these do not provide an answer specifically to what I am seeking. I have my 2 year A.A.S. Degree in computer programming, along with a networking certificate from a technical college. I also have been working at a small educational game development company for 3 years now in various positions, but steadily moving up and now as a lead programmer on a few projects. Some of the higher programmers I work with claim that no matter how much experience I develop it still will not mean as much as someone with a 4 year degree. Their argument is that most employers will look over my resume because of the common '4 yr' minimum requirement. I have also heard people state (not as many though) that experience is everything and that an employer would rather have someone that has worked in the field instead of a rookie fresh out of college. I have heard both sides of this argument, but am looking for a general consensus, or more arguments from both sides from the people who have been there, or are there.

• eBook editions of programming books

  - by Jon Hopkins

  (I'll get my justification for why this is on topic in early: programming books tend to have fairly specific formatting needs - code samples, tables, images and graphs - which are not common to all book types and are not necessarily well handled by eBook readers. Similarly they're used in different ways - you often dip in and out rather than read cover to cover.) I've just noticed that Don't Make Me Think by Steve Krug is available as an eBook edition for the Kindle (and presumably also for other readers) which set me thinking. There are certain advantages to eBook readers for tech books - primarily that you can carry a massive library of what would be heavy physical books around very easily. The downside is that certain eBook readers allegedly aren't particularly well equipped to cope with tables, code samples and so on and a book like Don't Make Me Think presumably makes extensive use of these sorts of things. So, the question, what are your experiences of reading and using programming books on an eBook reader and would you recommend it? I'm specifically interested in the latest generation Kindle but happy to hear about all devices - might be useful to state which one you use in the answer.

• BDD/TDD vs JAD?

  - by Jonathan Conway

  I've been proposing that my workplace implement Behavior-Driven-Development, by writing high-level specifications in a scenario format, and in such a way that one could imagine writing a test for it. I do know that working against testable specifications tends to increase developer productivity. And I can already think of several examples where this would be the case on our own project. However it's difficult to demonstrate the value of this to the business. This is because we already have a Joint Application Development (JAD) process in place, in which developers, management, user-experience and testers all get together to agree on a common set of requirements. So, they ask, why should developers work against the test-cases created by testers? These are for verification and are based on the higher-level specs created by the UX team, which the developers currently work off. This, they say, is sufficient for developers and there's no need to change how the specs are written. They seem to have a point. What is the actual benefit of BDD/TDD, if you already have a test-team who's test cases are fully compatible with the higher-level specs currently given to the developers?
