Super Python: three applications involving IRC bot master, MySQL optimization, and Website stress testing.

In my ongoing efforts to migrate my fun side projects and coding experiments from SVN to Git I’ve come across some of my favorite Python based apps – which are all available in their respective repos on BitBucket, as follows:

IRC Bot Commander

  • What it does: it’s an IRC bot that takes commands and does your bidding on whichever remote server the bot is installed on.
  • How it does it: the bot runs on whatever server you install it on, then it connects to the IRC server and channel you configured it to connect to and it waits for you to give it commands, then it execs the commands and returns the output to your IRC chat window.

Simple jQuery: how to validate IPv4 addresses and netmasks

Unfortunately jQuery doesn’t come with default form validation to check for ip-addresses or subnet masking. So without a long winded explanation here’s the code. Just include this as a separate JS file like the rest of your page’s JS.

// 'ipv4': IPv4 Address Validator
$.validator.addMethod('ipv4', function(value) {
    var ipv4 = /^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$/;    
    return value.match(ipv4);
}, 'Invalid IPv4 address');

// 'netmask': IPv4 Netmask Validator
$.validator.addMethod('netmask', function(value) {
    var mask = /^[1-2]{1}[2,4,5,9]{1}[0,2,4,5,8]{1}\.
    return value.match(mask);
}, 'Invalid IPv4 netmask');

You can use it like this.

        netmask:{ …

Percona Live UK, Santa Clara 2013, Fosdem and other conferences

The Winter season for conferences is catching up speed.


As I write this the DOAG conference in Germany is happening. It is one of the biggest (or the biggest?) Oracle user group conferences outside of USA. Many of my European friends in the MySQL space are talking there. As you know I have been a big fan of Galera Cluster for MySQL for over a year now, but I was perhaps a bit of an early adopter. Lo-and-behold, I was surprised to see the DOAG related press-release from SkySQL puts the creators of Galera first in their headline: Codership, SkySQL und weitere Top-Experten rund um das Thema ‘MySQL Datenbanken” in Nürnberg versammelt. Talk about crossing the chasm! Ralf Gebhardt, my other mentor …
