MySQL active-passive cluster | Your IT goes Linux – We will use the iSCSI Lun defined in our iSCSI cluster as a shared storage and we will run MySQL in active-passive (fail-over) mode using Pacemaker and Corosync cluster engine. The cluster will have to connect to the iSCSI target, mount the iSCSI partition on one node and start a MySQL service which has all its data on this partition.
Perl – [...] Perl has horrors, but it also has some great redeeming features. In this respect it is like every other programming language ever created. This document is intended to be informative, not evangelical. It is aimed at people who, like me: dislike the official Perl documentation at http://perl.org/ for being intensely technical and giving far too much space to very unusual edge cases learn new programming languages most quickly by "axiom and example" wish Larry Wall would get to the point already know how to program in general terms don't care about Perl beyond what's necessary to get the job done. This document is intended to be as short as possible, but no shorter[...]
Linux Performance – This page links to various Linux performance material I've created, including the tools maps on the right, which show: Linux observability tools, Linux benchmarking tools, Linux tuning tools, and Linux observability sar. For more diagrams, see my slide decks below.
AIXchange: Useful Storage Links – Here's an assortment of really good storage-related articles — the majority of which are found on IBM developerWorks — that are worth your time. While some of them are a few years old, they still provide relevant information.
agentile/S3-Media-Storage – Store media library contents onto S3 without cron jobs. This is more ideal for multiple web server environments. Because of the logic surrounding WordPress media uploads and the availability/order in which hooks/actions surrounding media uploading, we cannot get away from temporarily storing the uploaded file in the uploads directory. What this plugin will be able to do is to take that uploaded file, move it to S3, and delete the local uploaded file all in the same request.
Using AWS S3 with WordPress for Media Asset Storage | Ian Massingham’s Blog – As you know I recently migrated this blog from Google’s Blogger service to a self hosted WordPress installation running on the AWS Cloud. Since then, I have been working on improving the resilience and scalability of the new platform by using a few additional AWS features. One of the things I have changed is to move media assets, such as images, from the EC2 instance that runs the WordPress application to be externally hosted on AWS S3.
Timo’s procmail tips and recipes – Although there already is an abundance of procmail material on the net, here are some of my own tips and observations. This tips page is a companion of my Foiling Spam with an Email Password System page. The items on this page are in no particular order. There is some overlap in the items.
A tmux Crash Course – I’ve been using tmux for about six months now and it has become just as essential to my workflow as vim. Pane and window management, copy-mode for navigating output, and session management make it a no-brainer for those who live in the terminal (and especially vim). I’ve compiled a list of tmux commands I use daily to help me work more efficiently.

Bash: parsing arguments with ‘getopts’ | rsalveti’s random thoughts – Today I was writing some scripts, and in every script I wanted something to handle all input arguments, in a good way, so I could pass my arguments in any order and my program would know about it. I used ‘getopts’ before, but this time I decided to write some stuff here about it.
dayid’s screen and tmux cheat sheet – A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.
