  • How fast should an interpreted language be today?

    - by Tarbal
    Is speed of the (main/only viable) implementation of an interpreted programming language a criteria today? What would be the optimal balance between speed and abstraction? Should scripting languages completely ignore all thoughts about performance and just follow the concepts of rapid development, readability, etc.? I'm asking this because I'm currently designing some experimental languages and interpreters

  • Using PyUNO on Windows and CentOS

    - by Karim
    Is there any way to use OpenOffice's PyUNO without using the version of Python that comes with OpenOffice? I mean, can I install a package (on Windows and CentOS) that uses the version of Python that's already on the server? I'm trying to use OpenOffice in headless mode so that I can do document conversion with a script (ultimately on a hosted server running CentOS) but my development work is being done on Windows and occassionally the Mac). I'm having nothing but trouble getting this to work.

  • Does Ruby Version Manager interfere with the system scripts on Dream Linux?

    - by stephemurdoch
    Since Dream Linux has built in support for Ruby, I'm assuming it will work well as a Rails development environment, but I'm wondering if Ruby Version Manager will interfere with the system version of Ruby. Generally, when I use RVM, I disable/ignore the system version. How will the Dream Linux OS system scripts that are written in Ruby react to the presence of RVM? If I can't use RVM on Dream Linux, how easy is it to upgrade to newer versions of Ruby, without frazzling the system?

  • On what platform did these popular programming languages originate?

    - by speciousfool
    Perhaps you know the story of HTTP and HTML being developed on a NeXT computer. I am curious which platform served as the first home for these programming languages: Ada C C++ C# D Erlang Fortran Haskell Java Javascript Lisp Logo MATLAB ML Perl PHP Prolog Python R Ruby Scheme SQL Smalltalk I thought it might be interesting to reflect on how the machine and operating environment lead to different design decisions. Or to see if some architecture or operating system variant was particularly fruitful for programming language development. A question for the historians among us.

  • App Engine Django Form Uniqueness Validation?

    - by GeekTantra
    Is there a simpler way to use uniqueness validation with Django Forms in AppEngine? I understand that performance would be problem if we keep an uniqueness constraint but since the amount of data being added is very small performance is not a big concern, rather development time is a concern here. Any help is appreciated.

  • Why is it so hard to find a C++ 3d game tutorial

    - by Dave
    I'm planning on learning 3d game development for the iphone using a 3d engine, but because of lack of tutorials for the iphone I was planning on using C++ game tutorials and making the necessary changes. The problem is that I've had limited success when searching for things such as 'c++ 3d fps tutorial ' I dont really get anything useful. Are there any 3d c++ tutorials you can recommend?

  • What is the motivation behind c++0x lambda expressions?

    - by LoudNPossiblyRight
    I am trying to find out if there is an actual computational benefit to using lambda expressions in c++, namely "this code compiles/runs faster/slower because we use lambda expressions" OR is it just a neat development perk open for abuse by poor coders trying to look cool? Thanks. PS. I understand this question may seem subjective but i would much appreciate the opinion of the community on this matter.

  • Scrum backlog sizing is taking forever

    - by zachary
    I work on a huge project. While we program we end up meeting for endless backlog sizing sessions where all the developers sit down with the team and size user stories. Scrum doubters are saying that this process is taking too long and development time is being wasted. My question is how long should it take to size a user story on average? And does anyone have any tips to make these sizing sessions go quicker?

    I'd like to learn other people workflow when using either SVN or GIT.

Feel free to organize your answer not grouped by the tasks but grouped by whatever you think is relevant but please organize it by VCS/DVCS (please don't mix them). Thank you.

  • Setting up httpd.conf / mod_rewrite to redirect to codeigniter?

    - by Walker
    I'm sorry to ask this here, as I'm sure the solution is fairly easy but for the life of my I can't setup httpd.conf on my apache server to automatically load the code_igniter files. Instead I'm having to go into the folder itself localhost/trunk/etc/etc until I get index.php - which messes with some of the relative paths (our backend coder is gone for the week so I can't ask him, but he has already setup the rewrite rules on our development server).
