The mysql gem was removed from the rails 2.3.2. and you need to install it via the gem install mysql command But! There is a problem compiling it. seems that the mysql cant find the libmysql so..here are the options: yum install openssl openssl-devel Configure with path to mysql_config and install the mysql api via gem: # cd /usr/lib/ruby/gems/1.8/gems/mysql-2.7 # ruby extconf.rb --with-mysql-config=/usr/bin/mysql_config # make # ruby ./test.rb [hostname [user [passwd [dbname [port [socket [flag]]]]]]] # make install # gem install mysql Source: http://www.linuxweblog.com/ruby-on-rails-install And after that you can read the README.html located in the mysql gem directory :)

Last week I have the honor to make one wordpress website and I was amazed how good it is wordpress for such small personal websites.
Here I have found a list of wordpress templates in Internet (lost the source please forgive me).
Nice collection of links
- WordPress Theme Viewer
- Top WordPress Themes – Best Free Themes for WordPress
- WordPress Themes – The Best Of The Best!

Limit the index page of your website to show only posts from certain category
The right place for this code is in index.php
<?
// query all the posts for each cat
query_posts("cat=17"); // &showposts=2
?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<?php
// http://codex.wordpress.org/Conditional_Tags
// This is my second best choice! but with query_posts is nicer!
// if (!in_category('17') && is_home()) continue;
?>
How to display Posts only directly connected to a category (no subcategories)

Recently I have found my first trojan on my hard disk.
it is called 300lv because one bastered have taken from me 300lv to buy me cheap fdd-diskets and forgets to return me the money and the disketts.
So I have written this small self-installing app in return.
here it is for free download …
Awards: It is honered by the Bulgarian Academy Antivirus software.
The story continues. This code has no self-replication code in it. But in Bulgaria it seems that people like to do tricks to themselfs so after 2 years I have infected with my own trojan :)
And another of my friends has gone with his infected computer in the police asking them to arrest me /he doesnt know that I am the author of the trojan/ I was lucky that it was before 1994 and the police is sleeping.

Принципите на тестера:
Тестерите не ходят на работа, за да завързват приятелства.
Вярваме в Бог, всичко останало го тестваме.
Тестерите не чупят софтуера – той вече е счупен, когато пристига при тях.
Тестерите винаги отиват в рая – те вече са получили своята част от ада тук.
Ние не създаваме проблеми, просто откриваме вашите.
Това са бъговете – ако тези не ти харесват имам и други.
Ако не е счупено, значи не си опитвал упорито.
Добрият тестер има сърце на програмист… в буркан на бюрото си.
Тестерите не обичат да чупят нещата, те харесват разрушаването на илюзията, че тези неща работят.
Винаги има още един бъг.
Наша работа е да ви кажем, че отрочето ви е грозно.
“Да тестваш или не – туй не е въпрос!”
