There are many sites hosting free software projects. Some of them: www.sourceforge.net savannah.gnu.org gna.org github.com There are some lists for them here: * http://en.wikipedia.org/wiki/Category:Free_software_hosting_facilities * http://en.wikipedia.org/wiki/Comparison_of_open_source_software_hosting_facilities * http://www.dmoz.org/Computers/Open_Source/Project_Hosting/ In addition you may wish to browse, search or follow http://freshmeat.net/ or http://directory.fsf.org/ - they are directories for software with announcements. Since you used some scripting languages in the past (PHP), it looks like python would provide easier learning curve for you. I personally prefer compiled programming languages than scripting ones. Just a note - there is no dichotomy between compiling a language and it being a scripting language. For example, Perl, Python and PHP are all compiled into bytecodes, and CRuby will get a bytecode-based backend in ruby-1.9.x. What you probably mean is compiled into binary machine-code executables. This actually is possible to some extent with dynamic languages too. And just for the record see: * http://xoa.petdance.com/Stop_saying_script * http://www.perl.com/pub/a/2007/12/06/soto-11.html Java and the .NET-based languages are also compiled into bytecode, which is then executed. (Though there's an extra level of JIT). I have experience with both, Pascal and C vs. Basic and PHP and Perl. I want to learn Python, but I think there are less jobs with Python, so it's better I learn Java or C++. I think there are many jobs in Java and C++. Yes, for better or for worse. Personally, it has been my feeling that programs written in either Java or C++ seem incredibly difficult to get right, although in these cases from different reasons. Maybe working in C++ with a framework such as Qt is a good idea: http://www.shlomifish.org/open-source/portability-libs/ I have a multi-threaded program that someone who contacted me about http://www.shlomifish.org/rwlock/ wrote in C++ which works perfectly if you use printf and gets stuck quickly if you replace them with cout (I have a define for toggling them). Someone once gave me a link to a forum post which documented this, but this seems so basic that it should just work. He also was unable to use my RWLock (despite prefering it over the built-in POSIX rwlock) because it caused him more problems. Eventually, he said that he became convinced that he should have written his program in C instead of C++. There are also jobs in C# and .NET, but I prefer not to be stuck with Microsoft technologies. I don't like Microsoft, although I have been using their products for many years. I should note that C#/.NET/etc., while having originated from Microsoft, are not specific to Microsoft and http://www.mono-project.com/ has implemented them for most other OSes besides Microsoft. Recently I ported some Perl 5 code to Mono and C# (because the Perl code ran too slowly for my taste and what I tried to do). Without really knowing C# beforehand, it took me only a day to write that program (409 lines of C# code and 113 lines of Perl code to help test it (according to SLOCCount)), and it ran fine - started quickly and seems to have run much faster than the Perl code. So I was happy I chose C# for that instead of C which I know better. Naturally, this is just a relatively simple algorithmic and command line program, which isn't representative of the more complex software that C# tends to be used for, so I cannot comment on the suitability for it. What you are right about is that most C# and .NET shops will expect you to develop and deploy on Windows, because Mono is both incomplete and deploying .NET apps on non-Windows platforms may exhibit bugs or non-portabilities in the program. Someone once sent me a C#/.NET program he wrote and I couldn't run it on Linux because it used backslashes for paths. (This is naturally not limited to .NET - you can write Windows-specific software in almost any language). Also, thanks for

As for GUIs, personally I like wxwidgets which is cross platform and LGPL. The other main mature option is qt which, if things haven't changed again, has an option of a GPL license also for windows for open source projects and a commercial license for commercial projects. Actually, things have indeed changed: * http://lwn.net/Articles/315843/ - It was a pleasant surprise, then, when Nokia announced that the Qt library will be released under the LGPL version 2.1. * Same in Whatsup.org.il in Hebrew: http://www.whatsup.org.il/modules.php?op=modloadname=Newsfile=articlesid=6247 It kinda makes sense for Nokia to do that, because: 1. The GPL/Commercial dual-licence was the foundation of Troll Tech's (= Qt's Parent Company) revenue stream. However, for Nokia it is just a drop in the bucket, and not their main line of business. 2. Nokia should strive to make Qt as commonplace as possible so it will be commonly used and ubiquotous. 3. Some companies are still too scared of the LGPL to use it in their commercial projects (or even in-house ones) and would prefer to shell out the money for the commercial licence. I'm not saying this fear is rational, but that's life.[Licences] [Licences] - Someone I talked to said he would prefer not to use OpenSSL (which is under the original BSD Licence) for something he needed to do, because some of their customers were under the impression that open-source implied something GPL-like, and so had a more problematic licensing terms. But in any case, it's good news for people who would like to develop Qt-based software under non-GPL compatible licences, including proprietary ones. I should note that Qt contains QtCore and Wx contains WxBase which are two pure-API and non-GUI libraries that abstract away many system services such as data structures and threads. They may pose a good and tested alternative to STL/Boost . For other libraries like that look at: http://www.shlomifish.org/open-source/portability-libs/ wxwidgets uses the native gui, qt draws it's own. Each approach has it's merits (native look vs consistent look) If you look at wxwidgets, have a look at wxformbuilder for designing the GUI. Yes, there are many other differences between Qt and wxWidgets too. Regards, Shlomi Fish --

Re: Free software projects in Java or C++
By the way, I am thinking... since long ago I wanted to develop a free software (open source) project to automatically compose music. About 10 years ago I worked on a project called Speedy Composer (http://www.speedy.net/composer/), which is automatic composition of music. I developed it using Matlab, but there is currently no user interface. Maybe I will develop it using Java? What do you think? I will need to convert the Matlab files to Java, which might be difficult, but maybe after a few month's work I will be able to do it? What do you think? Then I will need to create a user interface program for composing music, or maybe using the web. 10 years ago I developed user interface using Visual Basic, but it was not complete. I might need help from another programmer, it would be difficult to do it alone. But I want to develop this program. If you want, you can listen to melodies composed on the website (Speedy Composer). Or write me and I will send you melodies off list.
