  • Magento caching, APC, eAccelerator Memcached, files, sqlite, Vanish, what’s the … happen? | Alex Paradise – Magento is slow! It’s how start most of the article about Magento cache optimization. Yes, Magento is slow and this because of the way the code is written, extreme object oriented. Stackoverflow say “It is written in an Enterprise Java idiom” and there are right. Anyway, we can’t change anything about it and in one side that let us lot of flexibility.
    So, Magento IS SLOW! And what’s can we do? There is many thing to do, many, many. But the most important one is to work around the cache.

  • MySQL-Galera cluster with HAproxy – Sébastien han – When I started working on Open Stack, I had to investigate about the HA of the nova component.

  • gitso – Gitso is to support others. – Google Project Hosting – Gitso is a frontend to reverse VNC connections. It is meant to be a simple two-step process that connects one person to another's screen. First, the support person offers to give support. Second, the person who needs help connects and has their screen remotely visible. Because Gitso is cross-platform (Linux, OS X and Windows) and uses a reverse VNC connection, it greatly simplifies the process of getting support.

  • Debian Clusters – This site is a series of step-by-step tutorials for anyone interested in building a Debian cluster. It is geared particularly towards those interested in a Debian cluster for education or research purposes. This site is being written alongside the construction of a real Debian cluster at my institute, starting from the ground (basic networking, DHCP, DNS, authentication) up through installation a queue/scheduler and scientific software.

    However, these tutorials and guides take some assumptions about users for granted, including basic Linux and Debian knowledge (see the Basic Linux Skills page for clarification and pointers to resources). This is not meant as an introduction to Debian or on how to cluster in general – thankfully, there are plenty of helpful tutorials and guides already in existence on those topics. A basic understanding of Debian and cluster technology will aid in following the tutorials.

  • Introduction to text manipulation on UNIX-based systems – Summary:  This introduction to text manipulation on UNIX platforms provides an overview of some common commands widely available and installed standard on most UNIX-based releases. Many times these standard utilities are ignored in favor of more modern text-processors such as Perl, Python, or Ruby, which are not always installed on a system. An introductory review of these tools helps practitioners who are learning UNIX or Linux or those who may be looking to renew forgotten knowledge.

  • jsFiddle – JsFiddle is a playground for web developers, a tool which may be used in many ways. One can use it as an online editor for snippets build from HTML, CSS and JavaScript.

We aim to support all actively developed frameworks – it helps with testing compatibility.

  • Configuring a site-to-site VPN between a Sonicwall and Linux Openswan – Mike A. Leonetti – I have had the fortune of having the challenge to set up a site-to-site (or BOVPN/Branch Office VPN) between a Sonicwall and Openswan. I have searched for other articles that cover this topic and found plenty of information that got me far enough to get some of it working. However, getting the whole thing working took quite some time and I found the guides to be incomplete. So for the sake of even my own remembrance, I will write a mini guide up. Of course I will link all of the guides I've used in a references section.
  • VPN Site-to-Site Openswan x ASA (Cisco) – House of Linux – Ladies and gentleman, today I am going to demonstrate how to integrate technologies from different platforms. It is possible to use Cisco to integrate with Windows and Linux using protocol such as LDAP. In this case the communication between Linux and ASA (Adaptive Security Appliances) is straight. We will only need to check the cryptography configuration and that it, the connection is established.
