  • Apache vs Nginx vs OpenLiteSpeed – As a hosting provider, we run hundreds of web servers with varying configurations. Some are tuned to work with large systems, some are tuned to work with lots of domains and some a tuned to be highly resource efficient.

  • Building a Raspberry-Pi Stratum-1 NTP Server – As an experiment, I purchased one of the low-cost credit-card-size Raspberry Pi computers, and have configured it to run NTP (Network Time Protocol).  I have also used this board with a GPS receiver with pulse per second (PPS) output to make a stratum-1 NTP server, but as I know little of Linux, it has taken some time to achieve this aim!  There are some helpful Linux commands scattered throughout this page.  These notes are almost as much for my own records for the next time I need to visit this project, but I hope they may be helpful to others.[…] [ via MD on ]

  • 5 easy tips to accelerate SSL – Unhandled expression – SSL is slow. These cryptographic algorithms eat the CPU, there is too much traffic, it is too hard to deploy correctly. SSL is slow. Isn’t it? HELL NO! SSL looks slow, because you did not even try to optimize it! For that matter, I could say that HTTP is too verbose, XML web services are verbose too, and all this traffic makes the website slow. But, SSL can be optimized, as well as everything!

  • 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!
