  • okvm – Open source KVM over IP technology – The okvm project team in 2005 developed an open source okvm KVM Development Kit – so engineers could cost effectively roll their own integrated KVM over IP control appliances. These okvm KVM Development kits included: one okvm PCI KVM Adapter card the okvm KVM over IP software source code the source information needed to manufacture the okvm PCI KVM Adapter card (circuit diagrams, BOM,PCD layout etc) A number of the KVM PCI cards were produced – sponsored by Opengear. However this project did not find traction in the developer community. So kits are no longer available and development in this branch of the project has stopped. Also Opengear now sells a proprietary KVM over IP solution!

  • FhGFS Wiki: Tips and Recommendations for Storage Server Tuning – Here are some tips and recommendations on how to improve the performance of your storage servers. As usual, the optimal settings depend on your particular hardware and usage scenarios, so you should use these settings only as a starting point for your tuning efforts.
  • Linux NAS optimizations ← BAFM – [...] Well, I recently had to flatten my archive NAS (well only the OS part … *wheeeh*). Since I didn’t have the chance to backup the old settings I had to do everything from scratch … And this time I decided, I wasn’t doing a script but rather the proper way. I spent a while reading through the Internetz about the various settings until I stumbled upon a Frauenhofer Wiki entry. From there I ended up writing those udev-rules and the sysctl configs…[...]

  • 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.
