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.

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 ]

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!

Mappare stampanti di rete con VBScript – Problematica semplice: una stampante di rete nuova, diversi PC che devono poterla utilizzare, non c’è kix che può aiutarmi ma c’è Active Directory con il suo Netlogon sempre valido. Dato che spiegare agli utenti come mapparsi una stampante potrebbe diventare una delle missioni più difficili di questo mondo e data l’urgenza della cosa, un piccolo trucco in VBScript può venire in soccorso per mappare tutto ciò che desideriamo in pochissimi secondi.
Extract Registry values from offline Registry file with RegFileExport – RegFileExport is a new command-line utility for advanced users that allows you to easily extract keys and values from offline Registry file located on external hard-drive and export them into a standard .reg file of Windows. RegFileExport doesn't load the file into a Registry hive like RegEdit, instead, it directly reads the Registry file and analyzes it. 
 
RegFileExport may also be able to extract keys and values from the Registry file even if the Registry file is corrupted and cannot be loaded by Windows

UNIX Performance Management – The purpose of this paper is to introduce the performance analyst to some of the free tools available to monitor and manage performance on UNIX systems, and to provide a guideline on how to diagnose and fix performance problems in that environment. The paper is based on the author’s experiences with AIX and will cover many of the tools available on that and other UNIX platforms. It will also provide some Rules of Thumb for analyzing the performance of UNIX systems. The paper has been updated to include some of the things that can be done in order to make sure that the web server will perform well.
