  • WordPress › HyperDB « WordPress Plugins – HyperDB is a very advanced database class that replaces a few of the WordPress built-in database functions. The main differences are: * HyperDB can be connect to an arbitrary number of database servers, * HyperDB inspects each query to determine the appropriate database.
  • ClusterFoundry Blog Highly-Available and Load-Balanced WordPress Cluster – Part 1 – This article explains on how to setup a load-balanced WordPress cluster in a master-slave configuration. The load balancer(HAProxy) sits in front of 2 or more web server nodes (1 Master and 1 Slave) which has the same contents. HAProxy does not only distribute requests, but also checks the health of the services running on the node. If one of the nodes are down, all requests will be redirected to the remaining nodes.
  • Deploying Scalable WordPress – The Official Rackspace Blog – […] The end result is a WordPress site that uses Cloud Load Balancers, Cloud Servers, and Cloud Files to deliver an easily scalable, modular configuration.[…]

  • Epoptes – Epoptes (ΕπÏŒπτης  – a Greek word for overseer) is an open source computer lab management and monitoring tool. It allows for screen broadcasting and monitoring, remote command execution, message sending, imposing restrictions like screen locking or sound muting the clients and much more! It can be installed in Ubuntu, Debian and openSUSE based labs that may contain any combination of the following: LTSP servers, thin and fat clients, non LTSP servers, standalone workstations, NX or XDMCP clients etc. Patches for other distros are welcome.
  • bcache – Bcache is a Linux kernel block layer cache. It allows one or more fast disk drives such as flash-based solid state drives (SSDs) to act as a cache for one or more slower hard disk drives. Hard drives are cheap and big, SSDs are fast but small and expensive. Wouldn't it be nice if you could transparently get the advantages of both? With Bcache, you can have your cake and eat it too. Bcache patches for the Linux kernel allow one to use SSDs to cache other block devices. It's analogous to L2Arc for ZFS, but Bcache also does writeback caching (besides just write through caching), and it's filesystem agnostic. It's designed to be switched on with a minimum of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high end storage arrays, and perhaps even embedded.

  • Portable Shell – Autoconf – When writing your own checks, there are some shell-script programming techniques you should avoid in order to make your code portable. The Bourne shell and upward-compatible shells like the Korn shell and Bash have evolved over the years, and many features added to the original System7 shell are now supported on all interesting porting targets.

  • harelba/q · GitHub – Have you ever stared at a text file on the screen, hoping it would have been a database so you could ask anything you want about it? I had that feeling many times, and I've finally understood that it's not the database that I want. It's the language – SQL. SQL is a declarative language for data, and as such it allows me to define what I want without caring about how exactly it's done. This is the reason SQL is so powerful, because it treats data as data and not as bits and bytes (and chars). The goal of this tool is to provide a bridge between the world of text files and of SQL. q allows performing SQL-like statements on tabular text data.

  • wg/wrk · GitHub – wrk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design with scalable event notification systems such as epoll and kqueue. [ via http://onethingwell.org/post/56882294128/wrk ]
  • Automate and manage systems installation with Cobbler – Cobbler simplifies system provisioning by centralizing the tasks that are involved in setting up and administering an installation server. This article discusses some of Cobbler's features, how to install it, and how to create a configuration suitable for automatically installing multiple client machines.
  • Cobbler – Linux install and update server – Cobbler is a Linux installation server that allows for rapid setup of network installation environments. It glues together and automates many associated Linux tasks so you do not have to hop between many various commands and applications when deploying new systems, and, in some cases, changing existing ones. Cobbler can help with provisioning, managing DNS and DHCP, package updates, power management, configuration management orchestration, and much more. (And you can integrate with chef or puppet)
  • Redhat I/O Scheduler Configuration in a Virtual Machine. – FATMIN – […] However, because of the fact that ESX is its own built in elevator, the Linux kernel's elevator is not needed, and in fact can hurt disk performance. So its best to disable the elevator inside your linux VMs […] Da controllare comunque dovrebbe andare anche su altre distro
  • RDP with NLA from Linux – Is there a way to connect to a Windows 2008 Remote Desktop Services with NLA from Linux?   Yes! FreeRDP is a fork of Rdesktop. Rdesktop seems to have stopped developement, so a fork is very welcome. NLA is still not in the main release, but it isn't hard to check out a copy from GIT and compile the latest source yourself.
