  • Build a file server with the Raspberry Pi | Linux User – We’ll be using Arch Linux as the operating system for our file server, because it is small,and has only the minimum packages required for a working system. This means that we can set up the file server without wasting resources on a graphical user interface and other unnecessary packages. Arch Linux comes with hardly any RAM allocated to the GPU by default, which is exactly how we want it for use as a headless server.
  • Registry Settings that can be Modified to Improve Operating System Performance – This section provides a description of recommended values for several registry entries that impact operating system performance. These registry entries can be applied manually or can be applied via the operating system optimization PowerShell script included in Windows PowerShell Scripts.

  • Top 10 things you must read about vSphere 5.1 – Welcome to vSphere-land! – There has been so many documents, white papers, videos and blog posts posted about the vSphere 5.1 release that it’s hard to keep up with them all. I have at least 250 links gathered in my vSphere 5.1 Link-o-rama and it is still growing. With so many links it’s easy to miss some of the really good ones so I thought I would put together a top 10 list that highlights the ones that you don’t want to miss.
  • Three things you should never put in your database | Revolution Systems – As I've said in a few talks, the best way to improve your systems is by first not doing "dumb things". I don't mean you or your development staff is "dumb", it's easy to overlook the implications of these types of decisions and not realize how bad they are for maintainability let alone scaling. As a consultant I see this stuff all of the time and I have yet to ever see it work out well for anyone.

  • Speeding up Magento with APC or Memcached – Tutorials – Magebase – We often hear complaints about how Magento is slow and performs poorly. Developers know, however, that performance is relative and that we can do a number of things to speed up a Magento site. This article will focus on configuring and using APC and/or Memcached. We have a resources section at the end of this article with links to more performance optimization techniques.

    The options obviously also depend on the specific hosting arrangement. I will assume for the purposes of this article, that you have control over your hosting server and are able to install the necessary add-ons and make configuration changes to Apache and PHP. If you are on a shared environment, you may have to check with your hosting support if you can apply the tips from this article. But, you know that you should at least be on a VPS if you are running Magento.

  • Speed up Magento with simple config tweaks – At Ionata we’ve been using Magento for quite a while now and the more sites we added, the slower our server seemed to become. Magento is quite a big chunk of software and can take up a lot of resources. However after doing some research and carefully tweaking our server configurations, we were pretty amazed to find performance gains of several hundred percent only by changing some settings.

    In this post you’ll find a summary of settings that can boost the speed and responsiveness of your Magento installation. Optimisation can be done for PHP, MySQL, Apache and Magento itself.

  • Apache 2 Basic Configuration on Unix-Like Systems | Nettuts+ – The Apache server is a service that runs in the background, waiting for requests from clients connecting to the ports it listens to, in order to take action. Apache either responds to those requests, or leaves related notes in its log files. Its behavior is controlled through its configuration, using what is known as directives (among other things). We’ll discuss the most basic directives in this article.

    A Soekris box I had lying around meets all requirements perfectly for a VPN-server. Here is how to set it up.

    Do you want less, but not boring? Then you want Simple Desktops.

  • missing disks, dump devices, mirroring, etc. – Waldemar Mark Duszyk – Since, we are pretty much always learning …. Some of us on a more elementary, intermediate, or advanced level but regardless of the level we all always learn or re-learn (because what we have mastered we had an ample time to forget – not doing it for a while), here it is a reminder of how to deal with a volume group (in this case it is rootvg which for some reasons lost one of it disks. The loss could be a function of SAN, VIO or other event. It could be a permanent loss – a disk is dead, broken, no longer functioning or the loss was/is temporary in nature; AIX kernel detected a timeout (without any disk errors associated with device failure) long enough for the kernel to mark the disks missing.
  • Authenticating RedHat with ActiveDirectory and Kerberos – Waldemar Mark Duszyk – One of my previous posts deals with authentication of RedHat LINUX using Tivoli Directory Server (TDS LDAP). As I was working on this project, my colleague Igor was busy configuring RedHat authentication with Active Directory and Kerberos (already configured on AD).
