• Proper permission and directoy location for Git Version Control

  - by CitadelCSAlum

  I am using Git Version Control on an remote server and I have set up a repository that multiple people will be using to push/fetch from. I have put the repo under /srv/subdir/git/.git I have been experiencing problem after problem it seems like. a) Is this location suitable for handling a project that will need to be accessed/modified by multiple developers and a designer? Or is there a better location? b)Do I need to modify the permissions on the subdir/ and git/ directories in order to allow remote access? If I do what is the appropriate permissions I should allow? I know this is a faily long request/question, but unfortunately like many other topics with well covered documentation, documentation does not always cover best practices. I would appreciate anybodies advice and suggestions? Thanks

• mac, java 1.5: javax.mail not recognized as a jar file

  - by Helpme

  hello fellow java developers, Having a little issue with creating a java application on a macintosh computer (snow leopard). I've set up my application in eclipse, added all of the appropriate jar files, but for some reason the code is not recognizing some of my variables as valid types. I've imported the libraries via import javax.mail.*; import javax.mail.internet.*; These libraries are not recognized by the application. BUT I've put them on the build path! Any advice on how to fix this?

• Branch for each developer in GIT repo

  - by Peter

  I'd like to move my project to GitHub from local svn repository. Multiple developers are curently working on this project. I was thinking that each developer should have their own branch in which they would commit changes. When manager review their work, he will merge it into master branch. I don't want separate repository for each developer as GitHub has limited number of private repositories. Is this a good idea? What are other alternatives?

• What is the best API in any language for Audio and MIDI music application development?

  - by noneme

  What, in your opinion, is the best API to utilize in developing an application that handles both realtime MIDI and audio input and output? This would be for an application that is used in the process of making music as opposed to playing audio or MIDI files. I'm aware that this may be a subjective question, but if you know of an API that is dominantly used for these purposes, please share it. I'm agnostic about which language the API is for, and I also don't care about portability. The real concern is for an API that is well documented, well designed (e.g. thought out and intuitive to developers using it), and actively maintained. OS portability would be nice, but it is second to having an API/Language that meets the previous requirements. Please note that the emphasis is not on API's for sound synthesis or for composing music with code. It is intended for the handling of sound file and MIDI data in a real-time context.

• 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).

• Advice about testing an application before release?

  - by Troy

  I would like to get some tips from peer developers about how you go about testing an application you developed, prior to release to QA. Keep in mind, this is a small scale application (requirements are verbal), and so doing formal testing processes wont work, especially, since your boss told you to develop this app quick, push it out the door. Despite the time restraints, I would like to make sure it is bug free, however, numerous times in the past, I have had the app sent back to me because clicking the "Reset" button, messes up the other controls alignment etc. I know there are people out there that develop small scale apps fast, and send them out with minimal bugs. How can I achieve that? I researched this post, but it didnt quite answer my question. Testing your code before releasing to QA

• How to nicely inform to the user that an unknown error has happened?

  - by Jaime Soriano

  There are several guidelines for error reporting, that are usually based on giving to the user useful information when he or she does something wrong, but to give this kind of information you need to be handling the error and know that it can happen. There are also tons of articles about designing 404 error pages. But, what can you do when it's a new, unhandled error provoked by a failure in the shoftware? Are there some guidelines about how to nicely report totally unexpected errors in a web site, as an unexpected error 500? What header message should be shown in that case? something like "Sorry, an unexpected error has ocurred" would be enough? What information should be given? Should it have mechanisms to help to report the failure to developers? Which ones?

• How to do a cost-benefit analysis for platform-level features?

  - by Callister Park

  I work on a development team that works closely with Product Managers. There is mutual agreement between the developers and Product Managers that there should be a business case behind every feature the development team builds. My question is, what is an effective way to make a business case for platform-level features that have higher up front cost but will provide long term benefits? For example, the development team would like to implement a plug-in framework. There is the higher up-front cost to implement a plug-in framework but delivering the subsequent features as plug-ins will be cheaper in the long run. This is obvious to everyone including the Product Managers. Is there a standard/simple way to express the cost-benefits? Is there a simple way to visualize it with a graph?

• 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?

• FreshBooks API Libraries

  - by Hristo

  Hello, I am posting this question as I couldn't find the answer (which is probably very easy, but apparently not for me) anywhere.. I am new to FreshBooks (no only the API) and I want to use it for some automatically generated invoices. I was trying to run some of the source code examples (the PHP and JS libraries in particular): http://developers.freshbooks.com/api/samplecode/ The problem is that I get an error message: "Connection error" Do I need to set up anything else in the example files besides my API and token obtained from the FreshBooks site? P.S.: I am running the examples from a local server but I don't believe that's the problem. Thank you very much in advance!

• How do I post dynamic information to Facebook from Flash?

  - by daidai

  I am building a Flash site and I want to be able to allow the user to post dynamically produced information to their Facebook wall, but I can't find out any information within the Facebook developers documentation. Its simple enough in Javascript/HTML: <script type="text/javascript"> function callPublish(msg, attachment, action_link) { FB.ensureInit(function () { FB.Connect.streamPublish('', attachment, action_link); }); } </script> <input type="button" onclick="callPublish('',{'name':'Post this to Facebook','href':'http://dev2.com','description':'this is some body test'},null);return false;" value="Preview Dialog" /> As you can see I don't want to create sessions or login or anything complicated, just post to info to their wall.

• How to create a cross-plataform application, doing the interface modules (Mac/Qt/GTK+) in a totally

  - by Somebody still uses you MS-DOS

  I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? Is it possible to create that mac interface in another OS using an IDE? How did the developers create this software with so many interfaces, in a independent way?

• 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.

• HttpsURLConnection failing intermittently to the same URL

  - by Arkaitz Jimenez

  I think I'm experiencing the same as http://groups.google.com/group/android-developers/msg/9d37d64aad0ee357 This is Android 1.5 SDK. I happen to call several times below code(which is in a method) with the same url and it fails intermittently. When it fails, there is no exception, the stream is empty so the readConnection fails, and getResponseCode returns -1. Global caching is disabled, setDefaultUseCaches(false); I suppose there must be some kind of url connection object pool somewhere. Any idea on how can I workaround this? HttpURLConnection connection = null; try { URL url = new URL(this.url); connection = (HttpURLConnection) url.openConnection(); connection.setRequestProperty("Authorization", "basic " + Base64Coder.encodeString(user + ":" + password)); connection.setRequestProperty("User-Agent", userAgent); connection.connect(); readConnection(connection.getInputStream()); connection.disconnect(); } catch (IOException ex) { reportException(ex, connection.getResponseCode()) } catch (ParserException ex) { reportException(ex, connection.getResponseCode()) }

• C++ build systems

  - by flo

  I will start a new C++ project (it may have some C components as well) soon and I am looking for a modern, industrial-strength (i.e. non-beta) build system. The software will be created by several developers in 3-5 years and will run on Linux (Mac OS X and Windows might be supported later). I am looking for something that has better comprehensibility, ease-of-use and maintainability than e.g. make but is still powerful enough to handle a complex project. Open source software is preferred. I started looking into Boost.Build, CMake, Maven and SCons so far and liked features and concepts of all of those, but I'm lacking the experience to make a decision for a large project.

• Code reviews for larger ASP.NET MVC team using TFS

  - by Parrots

  I'm trying to find a good code review workflow for my team. Most questions similar to this on SO revolve around using shelved changes for the review, however I'm curious about how this works for people with larger teams. We usually have 2-3 people working a story (UI person, Domain/Repository person, sometimes DB person). I've recommended the shelf idea but we're all concerned about how to manage that with multiple people working the same feature. How could you share a shelf between multiple programmers at that point? We worry it would be clunky and we might easily have unintended consequences moving to this workflow. Of course moving to shelfs for each feature avoids having 10 or so checkins per feature (as developers need to share code) making seeing the diffs at code review time painful. Has anyone else been able to successfully deal with this? Are there any tools out there people have found useful aside from shelfs in TFS (preferably open-source)?

• Is there any Android XML documentation?

  - by Eddified

  Is there any sort of xml reference? I found this which turned out to be invaluable for me http://groups.google.com/group/android-developers/msg/d334017d72909c79 but I can't figure out how I was supposed to know how to do that, had I not found that post. I know that the api reference has xml attributes listed for many of the classes... but what about xml tags? Where is it documented that I could build a shape using , , tags? I'd really like to know where I can find such documentation.

• 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.

• Ways to make your WCF services compatible with non-.NET consumers

  - by Mayo

  I'm working on adding a WCF services layer to my existing .NET application. This layer will be hosted in IIS and will be consumed by a variety of UIs, at least one of which will not use Microsoft technologies. I can make a Web service in WCF that is consumed by my .NET application. However, I'm concerned about things that work in the .NET world but not with other technologies. For example, simply throwing an exception from my WCF service works fine in .NET. But according to this article, one should approach exception handling with fault contracts to ensure compatibility with non-.NET consumers. The author labels this lack of foresight as The Fallacy of the .NET-Only World. Does anyone have any high level suggestions or links to articles that cover interoperability between WCF and non-.NET consumers? I realize I'm potentially working against the YAGNI principle. I'm only really looking to avoid things that will be incredibly difficult to overcome later when the developers of the non-.NET consumer report problems to me.

• Working effectively with unit tests / Anyone tried the in-assembly approach?

  - by CodingCrapper

  I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

• Do you use another language instead of english ?

  - by Luc M

  Duplicate Should identifiers and comments be always in English or in the native language of the application and developers? For people who are not native English speakers, which language do you use to declare variables, classes, etc. ? I had to continue a project from a Spanish guy. Everything was written in Spanish. Since this time, I have decided to use English identifiers ( variables, classes, file names) and write comments in french. Everything was in french before that. What are the general recommendations about that practice? Do you use English everywhere knowing that no English people will work on your project ? Edit : Here's a post from Jeff Atwood about this subject: The Ugly American Programmer

• Doctrine 1.2 Column Naming Conventions for Many To Many Relationships

  - by Alan Storm

  I'm working with an existing database schema, and trying to setup two Doctrine models with a Many to Many relationship, as described in this document When creating tables from scratch, I have no trouble getting this working. However, the existing join tables use a different naming convention that what's described in the Doctrine document. Specifically Table 1 -------------------------------------------------- table_1_id ....other columns.... Table 2 -------------------------------------------------- table_2_id ....other columns.... Join Table -------------------------------------------------- fktable1_id fktable_2_id Basically, the previous developers prefaced all forign keys with an fk. From the examples I've seen and some brief experimenting with code, it appears that Doctrine 1.2 requires that the join table use the same column names as the tables it's joining in Is my assumption correct? If so, has the situation changed in Doctrine 2? If the answers to either of the above are true, how do you configure the models so that all the columns "line up"

• 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.

• What was the most productive improvement suggestion you ever made for your team

  - by questzen

  I suggested the testing and functional teams to use Freemind map for jotting the functional flows and test steps. There was some paranoia but our module took it up and the QA teams were surprised to see near zero review comments. There was misconception among the team that there are doing more work. I assured them that by the time others would complete their work along with comment fixes, we would be going out for team lunchs and we did. The real returns came when the developers started refering to the created document in their discussions. So share your contribution(s).
