Identity
I am pretty much stereotypical programmer nerd and therefore I have some personal pet projects. In non-stereotypical fashion, I also have dancing as my hobby. The dances I do range from historical dances and Finnish folk dancing to contemporary dancing and Brazilian Zouk. My previous major interests have covered the art and culture that demoscene and Japan produce. I have been more or less active in organizations like Assembly, Alternative party and Nippoli.
Various social networking sites that I use:
Professional interests
My bachelor's and master's theses are both related in digital image processing, more specifically in two dimensional barcode recognition.
Tool collection
I prefer to have all-round skill set related to various software development areas instead of focusing in just one small subset. Though web development and its needs in *nix environments tends to dominate quite a lot.
- Programming languages: Python, C++, C, Groovy, Javascript, Java,
PHP, Perl, Matlab/Octave, Coffeescript, various assembly languages
and bunch of other languages, like Ruby, Scheme, Common Lisp and
Haskell, that I have touched but not necessarily done anything
bigger in them. And then Visual Basic for Applications.
- My programming style mainly leans towards defensive functional style programming. I try to take security related matters into account where feasible. I rely a lot on static and dynamic code analysis tools, as I know that they will catch many of the mistakes I do and help in modernizing my code. Fuzzing with american fuzzy lop and libFuzzer is also something that I'm nowadays more and more passionate about.
- I prefer working with high level abstractions and languages, but I can jump onto machine code if necessary.
- Markup languages: HTML/Jade, CSS/Stylus, LaTeX, reStructuredText, Markdown, XML, SVG.
- Databases: ZODB, MySQL, PostreSQL, SQLite, Memcached, MongoDB, Berkeley DB, Excel (hey, you can use this through ODBC =). And naturally many text formats that you might to use to store and retrieve information =)
- Build description languages: CMake, Makefiles, Ninja.
- Parser generators: ANTLR, Coco/R. Well, I have made some LL parsers for some self-created languages that fortunately are not used anywhere.
- Web development utilities: Node.js, Django, Grok, jQuery, Underscore.js, Backbone.js, Symfony, various web servers/caches like Apache, lighttpd, and Varnish. Generally, MVC based frameworks that are behind some server with optional caching.
- Largeish scale build, test, and release automation with Jenkins. Also making Jenkins fully programmatically managed so that every aspect of Jenkins can be version controlled.
- Infrastructure management with Ansible and shell scripts.
- Version control tools: Git, Mercurial, and Subversion. Tools that I don't want to touch: ClearCase and CVS.
- Computational engineering tools: OpenCV (C++), NumPy, Octave/Matlab. Mainly for image processing and for various generic machine learning tasks.
- Testing frameworks in various languages, like Python's unittest and doctest modules glued together with Nose, SimpleTest on PHP, Boost's test library, Java based jUnit and jMock for mock objects. And then Jasmine, Mocha, and Sinon.JS for Javascript applications. And if available tool set does not include an unit testing framework or licensing or dependency issues might make using some ready-made one too complicated, then I have written my own simple test runners to make up for that.
