  • 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. The “one size fits all” approach doesn’t work with web technology simply because the tools and the tasks vary so greatly.

  • How do I assign issues to multiple users – JIRA 6.4.x – Atlassian Documentation – JIRA is designed so that issues must be assigned to a single individual to prevent tasks from being overlooked. A team lead or manager should assign issues out to individuals, or your users will pick from a list of issues that they have the option to take on. However, if you want to configure JIRA to allow issues to be assigned to multiple users there are a few option for doing so: Managing Issues via a Queue Managing Issues via Group Ownership Managing Issues via a User Account Managing Issue via Sub-Tasks

  • 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 ]

  • 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!

  • Building a mail server on Debian 6.0 – The goal of this manual is to provide you with enough knowledge to feel confident in installing and maintaing your own mail server. Of course manuals like this already exist but during my search for knowledge I always felt like they were either not updated in a while or they just skip over some of the most interesting parts assuming you know what they are talking about[…]<br />

  • My Low End VPS Server – This document describes how to setup a Debian Linux VPS to replace your standard shared hosting account.  This document started out as a bunch of scribbles on scrap paper as I built a Virtual Private Server (VPS) into a fully functioning internet server.  It was notes on how I configured the server for the various pieces of the stack.  The need for the server was identified when I wanted to migrate my cPanel Shared Hosting account at Hostgator to a low end VPS for more control and freedom to run whatever software I wanted.  It was also a good opportunity to get back into Linux system configurations and serving web content.  As a collateral benefit, but not as the main drive, I was able to save a few dollars a month in web hosting costs.
