In writing my last article, I mentioned working with John Arbash Meinel, one of the lead developers of Bazaar, in attempting to diagnose and fix the performance bottlenecks apparent in using Bazaar with larger, history-rich projects like the MySQL Server. Well, after running some tests and building a custom branch of Bazaar that John pointed me to, I am happy to tell you that help is just around the corner. In my last article, you saw that doing a bzr branch lp:mysql-server took 91 minutes. This was a significant barrier to entry, I recognize. So, I think you'll be happy to see the results below, taken yesterday using John's patched-up Bazaar branch:

my.cnf is an option file(also sometimes called configuration file),which provides a way to specify commonly used options so they they need not be entered on the command line each time you run a program.This file is read by mysql server (mysqld) or any of the mysql client programs.

Here is a small my.cnf file
# Example MySQL config file for small systems.
# The following options will be passed to all MySQL clients

[client]
#password    = your_password
port        = 3306
socket        = /tmp/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]

Continuent is probably best known for its database clustering technology for MySQL, as well as PostgreSQL, but the company has for some time had its sights set on expanding beyond open source databases and enabling horizontal database scalability.

It has just taken a major step towards delivering on both counts with the launch of Tungsten, its new stack of open source middleware technologies designed to enable low-cost databases to scale horizontally for database failover and continuity.

Tungsten includes includes Sequoia, the existing …

Wow indeed, it's been almost a year already! How time flies... I left MySQL in July 2007, and had two months much needed holiday.

But one needs to live, and opportunity in Australia was clearly there, so I started Open Query in September and went for part familiar, part less familiar territory. The less familiar was consulting, in the sense that there had been no MySQL consulting in Australia by either me or MySQL directly, ever. I had done consulting before, in my old software development company in The Netherlands, as well as for others (I built a training & consulting firm for someone else).

The more familiar (in the MySQL realm) was of course training, as I'd been teaching courses here for years. The way that came about:In 2001, MySQL AB hired me as a tech writer for the docs, however my boss Kaj had just come in from Polycon which had developed MySQL training materials. Since I also had training experience, I …

Please allow me to take your mind on a little adventure! I was just reading A global Chinese software company in the next 20 years? about how China goes about acquiring technical know-how. It's not quite like what Japan did after WWII, it uses unique aspects of China, such as its size as well as its form of government.

Savio then makes a comment about "[...] piracy rates sky-high and IP legislation and enforcement in its infancy, [...]" which I think misses a very important point: China's government form is of course communist. One of the fundamentals of communism is that there's no individual ownership of things, most things are *communal* (hence the name "communism" ;-). Wikipedia writes "Communism is a socio-economic structure that promotes …

Alrighty, got flights in sardine-class with nasty airlines organised & paid, so I'm going to OpenSQL Camp 2008! See you all there?
