- 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[…]

- ii.com · Procmail Quick Start: An introduction to email filtering with a focus on procmail by Nancy McGough – rocmail is free/libre open-source software that is both a mail processor and a mail delivery agent (MDA). It can be used by either a system administrator or a user to automatically process and deliver incoming mail messages. It can also be used to re-process and re-deliver messages that are already in a mailbox. This Procmail tutorial is aimed at regular users, not system administrators.
- 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.

- ditaa – ditaa is a small command-line utility written in Java, that can convert diagrams drawn using ascii art ('drawings' that contain characters that resemble lines like | / – ), into proper bitmap graphics. This is best illustrated by the following example — which also illustrates the benefits of using ditaa in comparison to other methods 🙂

- BASH with Debugger and Improved Debug Support and Error Handling – The Bash Debugger Project is a source-code debugger for bash that follows the gdb command syntax. The version 4.0 series is a complete rewrite of the previous series along the lines of my other POSIX shell debuggers and other debuggers mentioned below.
- Opencall – Open Source Call Tracking Software – Call tracking is a method of monitoring inbound phone calls. It allows you to record conversations, track key statistics such as caller id, call duration, call source and streamline your sales, customer service and marketing. Opencall is the world’s first (and only) open source call tracking software. The software is available under the GPL v3 license, is written in PHP and utilises MySQL as the database platform. The original Opencall source code was written and developed by CallTracking Hong Kong to service clients in Hong Kong and other Asian countries. After 8 months of internal development the founder of CallTracking, Scott Bowler, decided to release their proprietary code to the public and change his business model to servicing companies who would make use of the open source call tracking platform. The major driver behind this choice was to open up the product to a global user base and encourage more rapid development of the platform.
