1. Awk (static since 2004)

    I was very interesting in shell scripting, i learnt that i could do many things in a easy way with awk.

  2. C (improving since 2004)

    I learn the basics at university, it has been very useful and powerful tool.

  3. C# (improving since 2003)

    I become interested in Mono, and so in C# various years ago. I think that C# is a great language, i like very much the standard API. I learnt it after java, so it was very easy.

  4. C++ (static since 2005)

    I can read code in c++ and make little changes, but i'm not a c++ coder at all.

  5. English (improving since 1993)

    I started in an academic where i was 7 years old. I've been in ireland three summers and i read/write daily in english.

  6. French (falling since 1994)

    I took french classes since my school, but i gave it up 6 years later.

  7. HTML (static since 1998)

    I can write/read this subset of SGML fluently. I use it daily.

  8. Java (static since 2003)

    With Java, i learnt all the basics of oo programming. I think that it was the first language that i had a deep knowdledge about it.

  9. JavaScript (static since 2005)

    I studied it for a project, it's very easy.

  10. JScript (static since 2005)

    It's identical to JavaScript, it is the MS implementation, i use it in the same project to code the server side.

  11. Lisp (improving since 2006)

    I started to study it this year at university and i've done a more or less serious programs with it.

  12. Perl (static since 2002)

    Perl has been a reference for all the web, i did various cgi with perl, it was a little painful but i'm still alive. I think that it's a great language, and it can be clean if the programmer wants so. I can write perl code if it's needed... but i will recommend to use Ruby or Python

  13. Prolog (static since 2005)

    I study it at university.

  14. Python (improving since 2002)

    Python become really popular various years ago... i did it a try and it was very easy! I use it daily. In Ubuntu, Emergya, and others organizations/companies that i am involved, python is the language most used. Since i got an Google Summer of Code project, debian-images-generator wich i'm developing in python i've improved a lot my knowledge about this language.

  15. Ruby (improving since 2005)

    Somebody told me about this language around a year ago, this is one of my favourites languages. I'm in love with ruby but i'm more comfortable with the libraries that python has, sorry ruby lovers, no stable libapt implementation with ruby }:-)>

  16. Scheme (falling since 2003)

    I study it at university. I didn't use it dialy.

  17. Shell Scripting (improving since 1999)

    I started in Gnu/Linux in 1999, i remeber a guide that was in www.kriptopolis.com. I started to code in bash, in a red hat 7.1. I use it daily.

  18. Spanish (improving since 1985)

    My natural language, i'm improving it since 14/07/1985.

  19. VisualBasic (falling since 2001)

    I had subject in my institute were we did a pair of games in visual basic 5.0 and 6.0. I remember that it was very easy, i can read Basic code, but i think it would be a little hard to write something without looking for a quick reference.

  20. XHTML (static since 2005)

    Well, i already know HTML so i just spend half an hour looking for the differences between HTML an this language. I did it because i beleive in standards.

Thanks to Joey Hess for this idea
