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
ONLYOFFICE™ Server Community Version – ONLYOFFICE™ – ONLYOFFICE™ Community Server is a freely downloadable open source software, distributed under the GNU Affero General Public License v.3. It comprises all the basic functional modules sufficient for comprehensive document and project management as well as any size team collaboration.
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 http://braindead.tumblr.com/post/115170631701 ]

Scaling PHP apps via PHP-FPM clustering | Jamie Alquiza – PHP-FPM is a way to move your busted PHP handling from one place to another. It's essentially a pool of processes ready for PHP interpretation through FastCGI. While Apache will service client connections and static content, PHP requests are pushed into PHP-FPM. PHP-FPM allows the creation of process pools, each pool having it's own spawning model (e.g. static number of processes, dynamic with min/max, etc.) and other configurations (what UID/GID to run as, listening socket, etc.). A typical setup would be to create a PHP-FPM pool per tenant in a shared hosting environment.
KERMIT – KermIT is an opensource IT management solution. KermIT integrates best of breed opensource components with a Web user interface and dashboard to provide a central management solution for IT systems and applications. It provides a consistent, secure framework and a scalable architecture. It manages Linux, Unix and Windows systems. 'Small picture' KermIT relies in the backend on Puppet and MCollective. The license of the developments is the GPL v.3 for the generic part of the source code.
Random Start Times For Cron Jobs With Puppet : mycfg.net – Periodic scripts which use a common resource can end up being configured to run at the same time for multiple hosts. The result is that tasks like puppet runs or backups can take longer since they are trying to run all at once instead of being staggered. One way to do this is to give each cron task unique times manually. Another way is to add a random sleep before the task runs. My preferred way is to use the fqdn_rand function in puppet. Here's how it works.
Optimize MySQL settings for Magento database – The Tuning Primer is a shell script that allows you to review the MySQL settings and make adjustments to increase Magento database performance and stability. The script will analyze MySQL statistics and provide you with recommendations on how to fine-tune your MySQL server.
The uptime of your MySQL should be more than 48 hours for correct script work. Only in this case there will be enough information for analysis. Tuning Primer script is compatible with all versions of MySQL starting from 3.23.
JQueryin | Switching Apache from Prefork to Worker MPM in RHEL / CentOS 5.x / Fedora 13 – I’m going to outline the process of switching from Apache’s default installation of MPM Prefork to that of MPM Worker. I will also be covering the proper installation of FastCGI (mod_fcgid) to further improve your server performance. This guide is ideally intended for individuals running on low-memory VPS servers as memory consumption will likely be far lower with the Worker MPM because it spawns threads as opposed to forking child processes. If you’re intentionally reading this article, you’re probably aware of the performance benefits gained.
