Upgrading to ruby-1.9.2-p290

Upgrading to ruby-1.9.2-p290 on my development machines (Windows and Linux) was a breeze. There were some extra steps needed to upgrade on the server:

1. rvm get head
2. rvm reload

After that, just:

3. rvm install ruby-1.9.2-p290
4. rvm –default 1.9.2-p290
5. rvm gemset create 3.1.1
6. rvm gemset use 3.1.1 –default
7. gem install rails –no-rdoc –no-ri

and ready to roll.

uninitialized constant Rake::DSL

Using Ruby 1.9.2, Rails 3.0.9, and rake 0.9.2

Installing ruby 1.9.2p0 and Rails 3.0.3 and getting it to work with MySQL on Windows

My development machine is a dual-boot Windows and Linux monster with pre-existing versions of Ruby, Rubygems, Rails, and MySQL. On the Windows side, I have a working version using ruby 1.86, rubygems 1.3.5, rails 2.3.8, and MySQL 5.1. The oldest [...]

SquirrelMail – change_sqlpass plugin

Found a bug in the squirrelmail change_sqlpass plugin. Made the ugly fix; gonna dive in and write a patch later.

The bug occurs in functions.php

There is a mismatch between:
function get_password_salt, where the program reasonably returns the value of the password salt when $csp_salt_static is empty and $csp_salt_query is not empty.

and:
function get_password_encrypt_string, in the switch statement,
it uses [...]
