     $(document).ready(function(){ $('select').change(function(){ var opt = $(this).find('option:selected'); console.log(opt.val()); });});

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><select id="1"><option value="dog">dog</option><option value="cat">cat</option></select><select id="2"><option value="chocolate">chocolate</option><option value="pizza">pizza</option></select>

   • Programming with Heuristics?

     Top Answer

     Answered Oct 30, 2012 · 6 votes

     At first you need to make yourself clear what a heuristic is. See for example wikipedia

     Heuristic ( /hjʉˈrɪstɨk/; or /hyoo-ris-tik/; Greek: "Εὑρίσκω", "find" or "discover") refers to experience-based techniques for problem solving, learning, and discovery.

     Moreover what means heuristic in computer science:

     In computer science, a heuristic is a technique designed for solving a problem quicker when classic methods are too slow, or for finding an approximate solution when classic methods fail to find any exact solution...

     This means it has nothing to do with a programming language. Ok, let us go step by step:

     1.) At first you have a problem.

     2.) Then you have to think for a solution of this problem. Maybe there exists a fast and exact algorithm. Then there is no need to use a heuristic. If there is no algorithm or any known algorithm is somehow bad (for example in the running time) you can think about to use a heuristic to solve.

     2.) And then at the end you can think about which programming language is the most appropriate to implement the solution for your problem.

     Of course it depends on you and your taste too and also on the problem you want to solve. Python and/or VB.NET are great choices for a big classes of problems.

   • Programming in c using cygwin

     Top Answer

     Answered Mar 20, 2017 · 4 votes

     I've used Cygwin on Windows 7 and Windows 2008 R2 for C development. The experience was painful: not only slow, but I never did manage to get my preferred editor (Emacs) working properly in Cygwin.

     You could try a live distro of Linux that you could boot from a USB memory stick. That way you could program in C to your heart's content without having to install any software on your PC. I'd recommend Puppy Linux if you took that approach.

     Alternatively, you could install a virtualisation product (like VirtualBox) and create a Linux VM. In that case, I'd suggest using Ubuntu.

     My experience is that either the live distro or VM approach would be better than using Cygwin as a development environment.

   • programming and running crystal on windows

     Top Answer

     Answered Mar 06, 2018 · 8 votes

     In the wiki, there is a guide on working with Crystal on Windows: https://github.com/crystal-lang/crystal/wiki/Porting-to-Windows

     However, Windows support is very limited for now, but it's taken some steps lately.

     The ongoing efforts for porting to Windows are tracked in https://github.com/crystal-lang/crystal/issues/5430 As you can see, many basic features are still pending. Right now, you probably will not be able to compile any useful program on Windows.

     But you can very easily develop on Windows in a Linux environment using Windows Subsystem for Linux. Instructions are in the docs: https://crystal-lang.org/docs/installation/on_bash_on_ubuntu_on_windows.html
