Introducing Woclema, weblogging software for discriminating people

22 August 2007 12:42:35 my software, update, woclema

Weblogs. Or blogs. They seems to be everywhere. Everybody but me blogs. Should I start a blog of my own? Most weblogging software seem to run on PHP and MySQL (see Wikipedia article on weblog software), and I shun both. What a perfect opportunity to waste countless hours in reinventing the wheel.

Embrace Woclema, weblogging software for discriminating people like yourself. :-) Written in Perl and using PostgreSQL as database engine, highly original name Woclema stands for Weblog, Originally Command Line Editable/Manageable. Woclema comes with sophisticated front-end which, erm, allows you to feed in your entries using your favourite text editor and shell, be it combination of zsh/vim, Bash/Emacs, or any of the countless combinations.

Seriously though, Woclema really started as simple Perl/PostgreSQL weblog thingie that could be edited and maintained with command line tools. Woclema supports entry categories, user comments, and permanent links (as long as primary keys in DB stay the same). It uses CSS for layout, so it should be fairly easily themed. Currently there is no spam protection for comments, nor any kind of interface to post or maintain the weblog using web-browser. However implementing neither should be a problem.

Woclema does not have any kind of markup language, nor does it hold your hand to prevent you from hurting yourself. It allows editors to insert HTML without artificial limitations. It does not allow others to do the same -- for comments, text is HTMLized, i.e. potentially dangerous characters are written as entities such as <.

Grab the sources and join the revolution in weblogging software. :-)

Optimisation with GCC and its impact on performance

22 August 2007 10:43:22 software, update

There has been lot of discussion about compiling GNU/Linux from scratch, and performance boost related to it. I have never been a big believer of this -- except for applications such as multimedia encoding. How much does optimisation really matter?

From what I learned, optimising for athlon-xp (or i686) instead of i386 will get you around 15% performance boost with processing multimedia content, but for amd64 it's all the same.
