• .classpath and .project - check into version control or not?

  - by amarillion

  I'm running an open source java project that consists of multiple modules in a tree of dependencies. All those modules are subdirectories in a subversion repository. For newcomers to our project, it's a lot of work to set all that up manually in eclipse. Not all our developers use eclipse. Nevertheless, we're considering to just check in the .classpath and .project files to help newcomers to get started. Is this a good idea? Or would that lead to constant conflicts in those files? Is there an alternative way to make the project easy to set up on eclipse?

• How are CD Keys generated?

  - by The Rook

  CD Keys are the defacto-standard as an anti-piracy measure. To be honest this strikes me as Security Though Obscurity, although I really have no idea how CD Keys are generated. What is a good (secure) example of CD Key generation? What cryptographic primitive (if any) are they using? Is it a message digest? If so what data would they be hashing? What methods do developers employ to make it difficult for crackers to build their own key generators?

• Pros and cons of Localisation of technical words ?

  - by paercebal

  This question is directed to the non-english speaking people here. It is somewhat biased because SO is an "english-speaking" web forum, so... In the other hand, most developers would know english anyway... In your locale culture, are technical words translated into locale words ? For example, how "Design Pattern", or "Factory", or whatever are written/said in german, spanish, etc. etc. when used by IT? Are the english words prefered? The local translation? Do the two version (english/locale) are evenly used? Edit Could you write with your answer the locale translation of "Design Pattern"? In french, according to Wikipedia.fr, it is "Patron de conception", which translates back as "Model of Conceptualization" (I guess).

• Need Language/Career Path Advice

  - by Cain

  I am interested in getting a few Microsoft Certs and I am currently facing the option for .NET Framework app development language. My choices are C++, C#, and Visual Basic. I have some experience with Java and Visual Basic .NET but I honestly would like to know what the best would be for developing stand-alone applications in a workstation (local) environment. This is for my career and honestly, 90% of the developers are all experienced in the above three languages and I wanted to improve my chances of staying employed by learning/certifying myself on my own time.

• Is everyone baking the same CI cake?

  - by Brett Rigby

  I can't help but wonder about this whole Continous Integration process and wanted to know what you think about it all. From my perspective, we're constructing our own 'flavour' of NAnt/Ivy/CruiseControl.Net in-house and can't help but get the feeling that other dev shops are doing exactly the same work, but then everybody is finding out the same problems and pitfalls with it. I'm not complaining about NAnt, Ivy or CruiseControl at all, as they've been brilliant in helping our team of developers become more sure of the quality of their code, but it just seems strange that these tools are very popular, yet we're all re-inventing the CI-wheel. Is there a pre-made solution for building .Net applications, using the tools mentioned above, and if so, why aren't we all using them??

• How big teams work with database

  - by Michael Riva

  Lets say I have a team, 20 developers. And we are making a project on .net. In team every one can easy create their tables according to their modules working on it. And we think to use an ORM, can you tell me how can and which ORM tools for good to working with team. Is there any proven way? I m asking becouse I never work with a team, so I dont know the best practices. So you guys what kind of pattern you use?. I realy wonder. The team members can write their unit tests and supply necessary design patterns. What kind of approach I need to create to manage team? What kind of ORM tools that we have to use?

• How to programatically create and read WEP/EAP WiFi configurations in Android?

  - by Als

  How to programatically create and read WEP/EAP WiFi configurations in Android? I have seen a number of people struggling on this very question on various forums and all across the community. I know this is not that straight forward(especially EAP) to figure out because When I wanted to acheive the same I too struggled quite a lot.Well, all the hard work of code analysis and searching various implementations on the internet done with I was finally able to acheive the goal. All the credit goes to number of open source projects and their developers. I would like to share this knowledge with all, Since SO encourages this: "It's also perfectly fine to ask and answer your own question, as long as you pretend you're on Jeopardy: phrase it in the form of a question." Part 1: Creating a WEP WiFi configuration programatically. Part 2: Read a WEP WiFi configuration programatically. Part 3: Read a EAP WiFi Configuration programatically. Part 4: Save a EAP WiFi configuration programatically.

• Best Tools for Software Maintenance Engineering

  - by Pev

  Yes, the dreaded 'M' word. You've got a workstation, source control and half a million lines of source code that you didn't write. The documentation was out of date the moment that it was approved and published. The original developers are LTAO, at the next project/startup/loony bin and not answering email. What are you going to do? {favourite editor} and Grep will get you started on your spelunking through the gnarling guts of the code base but what other tools should be in the maintenance engineers toolbox? To start the ball-rolling; I don't think I could live without source-insight for C/C++ spelunking. (DISCLAIMER: I don't work for 'em).

• Reusing of a PreparedStatement between methods?

  - by MRalwasser

  We all know that we should rather reuse a JDBC PreparedStatement than creating a new instance within a loop. But how to deal with PreparedStatement reuse between different method invocations? Does the reuse-"rule" still count? Should I really consider using a field for the PreparedStatement or should I close and re-create the prepared statement in every invocation? (Of course an instance of such a class would be bound to a Connection which might be a disadvantage) I am aware that the ideal answer might be "it depends". But I am looking for a best practice for less experienced developers that they will do the right choice in most of the cases.

• How is the Trac Project List page customised?

  - by Completenutter2

  We've been using Trac for a while now for our developers only. However we are now opening it up for our (internal) clients. We have a project listing page (based on the default one that comes with Trac). What we'd like to do, is display more information about the project than what is currently available. I have searched google and here, to see if I can find how to get more information. There seems to be a variable called $project which has .name, .description and .href as attributes. Is there somewhere, a list of the attributes available? Or perhaps a different solution altogether that will allow us to display more information on the project list page. Such as the number of open tickets etc.

• Browser Compatablitiy, Support, Modern Browsers and older Versions.

  - by smoop

  This is a question to all web-developers working in the industry more than a few years. Today the server guy at my work told me that his browser didnt render a google font I used on a site properly, so I checked his browser - it was firefox 3.5. (google font Raleway).. This made me think.. I know for some of our sites its a requirement to support IE6 (larger corperate sites) but for the rest (personal sites) should I be looking at developing for all incrments of firefox, chrome, IE and safari???? Does your company still support IE6? Does your company support previous versions of modern browsers or just the latest ones? and finally, has anyone else had this problem with FF 3.5 and Google Hosted font Raleway..(the font displays extra extra thing so the font is almost unreadable) If anyones interested I found a working solution to my font problem here: http://www.jshsolutions.net/google-webfonts-cross-browser-fix-howto/ Sam

• Git - Committing Machine Specific Configuration Files

  - by Gordon

  A common scenario when I develop is that the codebase will have several config files which require machine specific settings. These files will be checked into Git and other developers will always accidentally check them back in and break someone else's configuration. A simple solution to this would be to just not check them in to Git, or even to additionally add a .gitignore entry for them. However, I find that it is much more elegant to have some sensible defaults in the file which the developer can modify to suit his needs. Is there an elegant way to make Git play nicely with such files? I would like to be able to modify a machine-specific configuration file and then be able to run "git commit -a" without checking that file in.

• Tooltip equivalent for touch devices?

  - by eteubert

  Hey folks, Touch devices are on the rise. More and more website developers try to optimize their pages for those devices. Until recently the most common solution was to build a mobile version for the website. But with tablets this will most likely change to adjusting the original pages to be touch compatible. One big issue I encountered are tooltips. There are some websites and web applications relying heavily on storing important informations in some kind of tooltip triggered by hovering the mouse arrow over some interface element - which does not exist on touch devices. So what do you think is a good universal way to adopt these pages without redesigning the site from scratch? Does this universal way even exist? My first idea was a tiny touchable question mark but this would hardly be big enough for a finger.

• How can unit testing make parameter validation redundant?

  - by Johann Gerell

  We have a convention to validate all parameters of constructors and public functions/methods. For mandatory parameters of reference type, we mainly check for non-null and that's the chief validation in constructors, where we set up mandatory dependencies of the type. The number one reason why we do this is to catch that error early and not get a null reference exception a few hours down the line without knowing where or when the faulty parameter was introduced. As we start transitioning to more and more TDD, some team members feel the validation is redundant. Uncle Bob, who is a vocal advocate of TDD, strongly advices against doing parameter validation. His main argument seems to be "I have a suite of unit tests that makes sure everything works". But I can for the life of it just not see in what way unit tests can prevent our developers from calling these methods with bad parameters in production code. Please, unit testers out there, if you could explain this to me in a rational way with concrete examples, I'd be more than happy to seize this parameter validation!

• Visual Studio 2008, MSBuild: "replacement" projects

  - by liori

  Hello, My solution has a library project which needs a special environment to be built (lots of external libraries and tools)... but it is not vital to our application. We'd like to avoid installing these tools when not necessary (most of our developers work on other parts of code). We have created another project which has the same API, but has an empty implementation and is compilable without those external tools. I'd like to be able to easily switch between those projects and still get all the references in other projects correct. I don't know VS/MSBuild very well, but willing to learn whatever is necessary. Is it possible? I am looking for ideas... We're using Subversion, and solutions involving some hacks inside VCS are also welcome.

• post-install hook for a particular gem

  - by Henry Flower

  Here is what I've googled: http://www.mail-archive.com/[email protected]/msg02168.html Gem.post_install do |installer| puts "!!! #{installer.spec.full_name} INSTALLED !!!" end But where to put this snipped? If I put it in my Rakefile and/or src_of_myproject/lib/rubygems_plugin.rb file, than build the gem, install it--but the expected string is never printed after the installation. I'm totally confused. How to embed the post-install hook into the gem spec? Update: it's getting more interesting. If I put Gem.post_uninstall hook in src_of_myproject/lib/rubygems_plugin.rb--that hook works. Gem.post_uninstall do |uninstaller| puts "!!! #{uninstaller.spec.full_name} UNINSTALLED !!!" end Hm... And wtf is with Gem.post_install?

• Python unittest with expensive setup

  - by Staale

  My test file is basically: class Test(unittest.TestCase): def testOk(): pass if __name__ == "__main__": expensiveSetup() try: unittest.main() finally: cleanUp() However, I do wish to run my test through Netbeans testing tools, and to do that I need unittests that don't rely on an environment setup done in main. Looking at http://stackoverflow.com/questions/402483/caching-result-of-setup-using-python-unittest - it recommends using Nose. However, I don't think Netbeans supports this. I didn't find any information indicating that it does. Additionally, I am the only one here actually writing tests, so I don't want to introduce additional dependencies for the other 2 developers unless they are needed. How can I do the setup and cleanup once for all the tests in my TestSuite? The expensive setup here is creating some files with dummy data, as well as setting up and tearing down a simple xml-rpc server. I also have 2 test classes, one testing locally and one testing all methods over xml-rpc.

• Running sites on "localhost" is extremeley slow.

  - by seanxe

  Hello all, Having real trouble using my local host to test sites. It runs extremely slow! Sometimes up to a minute to load a page. I'm using firefox and the sites i'm testing run fine on other developers in my office local machines/ on the production server. I've gone through the normal things :- Disabled IPv6 Not running in debug mood Put the site in the highest app pool (High Isolated) on IIS 6. Taking of firewalls etc. The problem only seems to occur when hitting pages which contain some form of .net code in the code-behind. Appreciate that this a little bit of a vague topic / stab in the dark but would appreciate any sort of advice - it's horrible waiting a minute each refresh to try out a change! Cheers, Sean.

• What are some good ways to promote my Android application?

  - by Bryan Denny

  I'm a new Android developer and I just released a free, open source tipping calculator app called Tippy Tipper. I created this app to get myself familiar with Android and to hopefully provide a good example app for other new developers to look at. Now that I've overcome the challenges of learning how to program, test and release my Android app, I've come across a new challenge: marketing! What are some good ways to promote my app to the Android community? Can anyone with some experience talk about how they did this successfully with their own app?

• Why is it a bad idea to use ClientLogin for web apps in the Google API?

  - by Onema

  I just picked up the Google API today to allow some users of our site to upload videos to our own organization YouTube account. I Don't want our users to know our user name and password, but rather give them the option if they want to upload videos to youtube or not. If they choose to do it, they check on a check box and hit the submit button. I keep seeing over, and over in the Developers guide that ClientLogin, which to me looks like the best option to implement what I want to do, is not a good idea for user authentication in web applicaitons. The "AuthSub for web applications" doesn't seem to be the best mechanism for what I want to implement! Any ideas on what to do? Thank you

• assistance with fxcop

  - by amateur

  I am at present developing a mvc4 project that comunicates to a set of wcf services. I am setting such up in tfs build for a team of developers. I am very much a newbie to fxcop and code analysis in general. I am currently researching it and have some questions following this: Is it recommended to use the rules that come with fxcop? Should it be included as a build task during builds? What is the value from it? Are there guidelines to what rules to abide by or is it best to go with the default? Is it correct to run the analysis as a post build event? I am a newbie to fxcop and would like some feedback. I am as it is integrating stylecop in to my build.

• Constantly changing frameworks/APIs - how do we keep up?

  - by Jamie Chapman

  This question isn't really for any specific technology but more of general developer question. We all know from experience that things change. Frameworks evolve, new features are added and stuff gets removed. For example, how might a product using version 1.0 of the "ABC" framework adapt when version 2.0 comes along (ABC could be .NET, Java, Cocoa, or whatever you want)? One solution might be to make the frameworks backward compatible; so that code written for 1.0 will still work in version 2.0 of the framework. Another might be to selectively target only version 1.0 of the framework, but this might leave many fancy new features unused (many .NET 2.0 apps seem to do this) Any thoughts on what we as developers should do as best practice to keep our technologies up to date, whilst not breaking our applications?

• C# where keyword

  - by Carra

  Our Indian overseas developers have written the following piece of code (C# 2.0): public abstract class ObjectMapperBase<T> where T : new() { internal abstract bool UpdateObject(T plainObjectOrginal, T plainObjectNew, WebMethod fwm, IDbTransaction transaction); } Inheritor example: public abstract class OracleObjectMapperBase<T> : ObjectMapperBase<T> where T : new() { internal override bool UpdateObject(T plainObjectOrginal, T plainObjectNew, WebMethod fwm, IDbTransaction transaction) { //Fancy Reflection code } } I've never seen the where keyword before after the class name. What does this do?

• How to get Field Labels from PIMItem - Blackberry

  - by Taha

  How can we get Field Labels from PIMItem. The following code is with PIMList String label = pimList.getAttributeLabel(blackBerryContact.getAttributes(Contact.TEL, i)); But i have PIMItem. There is a method PIMItem.getPIMList() which returns null for me in the code below. THE API at http://www.blackberry.com/developers/docs/5.0.0api/index.html says "getPIMList() Gets the PIMList associated with this item." Below is sample code that i am trying to achive - // Load the address Book and allow the user to select a contact BlackBerryContactList contactList = (BlackBerryContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY); PIMItem userSelectedContact = contactList.choose(); // Now get the Field labels for contact numbers for userSelectedContact

• Agile version control?

  - by Paul Dixon

  I'm trying to work out a good method to manage code changes on a large project with multiple teams. We use subversion at the moment, but I want more flexibility in building a new release than I seem to be able to get with subversion. Here's roughly I want: for each developer to create easily identifiable patches for the project. Each patch delivers a complete user story (a releasable feature or fix). It might encompass many changes to many files. developers are able to easily apply and remove their own and other patches to facilitate testing release manager selects the patches to be used in the next release into a new branch branch is tested, fixes merged in, and ultimately merged into live teams can then pull these changes back down into their sandboxes. I'm looking at stacked git as a way of achieving this, but what other tools or techniques can deliver this sort of workflow?
