  • Are you a self taught programmer or did you take a programming course?

    - by workinprogress
    Lots of developers I know were self taught programmers including me. I was wondering how much of the developer community learned programming by taking a course in school or by experimenting, asking questions on forums, reading online articles, and just making it up as you go along? Post whether you were self taught or took classes, what language you program in, and anything else that may be interesting. P.S. Books count as self taught.

  • Are there any simple languages implemented using ANTLR or similar?

    - by etheros
    I'm trying to build a simple interpreted language for learning purposes. I've read countless theory and tutorials on ANTLR and JavaCC, but I can't figure out how to actually make it do something useful. I learn best by "taking something apart and putting it back together again", so, are there any working examples of simple languages implemented with the help of tools such as ANTLR, or similar? Something like the following might be nice: x = 1 if x == 1 print "true"

  • Why would I want to use server-side JavaScript?

    - by Joseph Silvashy
    I'm confused, I regularly read talk of server-side JS, why would I want to use that? It seems like it would execute way slower than pretty much any other language, it also lacks many conventions that more sophisticated languages have. Is it possible to hand entire objects from the client to the server, manipulate them and return them back? Just struggling to understand the concepts of it.

  • C precision of double: compiler dependent?

    - by yCalleecharan
    Hi,on my 32-bit machine (with an Intel T7700 duo core), I have 15 precision digits for both double and long double types for the C language. I compared the parameters LDBL_DIG for long doubles and DBL_DIG for doubles and they are both 15. I got these answers using MVS2008. I was wondering if these results can be compiler dependent or do they just depend on my processor? Thanks a lot...

  • Mocking a Wcf ServiceContract

    - by Michael
    I want to mock a ServiceContract. The problem is that Moq (and Castle Dynamic-Proxy) copies the attributes from the interface to the dynamic proxy which Wcf don't like. Wcf sais: The ServiceContractAttribute should only be define on either the interface or the implementation, not both.

Async.Sleep 200 for cmd in theDrawing do do! this.Execute(cmd) } |> Async.StartImmediate ) Can you help?

  • parallel java libraries

    - by jetru
    I'm looking for Java libraries/applications which are parallel and feature objects that can be queried in parallel. That is, there is/are objects in which multiple types of operations can be made from different threads and these will be synchronized. It would be helpful if someone could ideas of where I could find such applications as well. EDIT: Actually, language doesn't matter so much, so C++, Python, anything is welcome

  • Mathematics - Why is Differential Calculus (MVP) in PHP a tabu?

    - by Email
    Hi I want to do a Mean-Variance-Optimization (Markowitz) but i never found anything written in php that does this. MVP needs differential calculus. Can it be done in php and why arent there any classes/works from universities? For a webapplication (regarding performance) would another language be the better choice to handle heavy calculations? Thanks so much for any help/answer on this

  • How to create dynamic menulets in OSX

    - by taw
    I want to put a dynamically generated icon (not static image) + possibly a tiny bit of text in OSX menu bar. If possible I'd prefer to do it from Ruby or some other convenient scripting language, but I'll deal with Objective C if that's the only way. How do I do that?

  • What grammar based parser-generator tools exist for ruby?

    - by cartoonfox
    What open source (preferably gem-based) parser-generator options do I have in Ruby? I've used (flex&bison)|(lex&yacc) from C in the past, and I'm comfortable with BNF-style specifications. I've heard of treetop, but it looks a bit alien and verbose compared to yacc... Purpose: I want to convert my text markup language to a BNF and generate the parsing code. I think it's a better strategy than my first-order solution: http://github.com/dafydd/semantictext/blob/master/lib/semantictext/rich_text_parser.rb

  • What side project/research should be chosen to increase my Marketability

    - by CheesePls
    I am a Junior CS Major at a Javaschool and I find myself having an easy time and thought there may be some good project or a language to learn or research in this newfound free time. What would you recommend so as to increase my ability to find a good job(somewhere that allows for continuous learning and treats its programmers well)after college? My thoughts were learning Scheme, making a working Zelda-like game(the original), find some open source project to help with.

  • HTML Types - Learning Order?

    - by Gabe
    I've decided that today - as soon as this question is answered, in fact - I'm going to dive into learning HTML. But, looking online, I've noticed there are many types: HTML, XHTML, HTML5, and so on. So, which should I start with? In what order should I learn them? And, for that first language, where should I learn at?
