Many times, you want to execute a command not only on one server, but also on several servers. For example, find out * Version of kernel * Version of Apache web server * Update static html or images files on all web servers via rsync * Find out user information, server information, memory usage etc * Security/patch checking tentakel I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group.

Virtualmin is a uniquely powerful and flexible web server administration tool. It is unmatched in features and ease of use. Based on Webmin, it offers a wide array of productivity-enhancing tools for hosting providers, web developers, web designers, and end users.

A good way to see how your Web applications and server will behave under high load is by testing them with a simulated load. We tested several free software tools that do such testing to see which work best for what kinds of sites. If you leave out the load-testing packages that are no longer maintained, non-free, or fail the installation process in some obscure way, you are left with five candidates: curl-loader, httperf, Siege, Tsung, and Apache JMeter.

With so many browser out there in the wild, working as a Web Developer certainly is not an easy job these days. Thankfully, over the last years, decent tools have been developed by bright people that make developing and debugging of code easier for the developer. But sometimes, it is not easy to keep track which tools are at a Developer’s disposal (and which are actually usable). The following article seeks to list the best tools available and quickly describing how to activate/install/use them.

The Geotag Icon is intended as a web "standard" icon for identifying geotagged content to humans. The advent of inexpensive GPS devices and free tools like Google Maps or Flickr Map mean that more and more people are associating their content (typically blog posts or photos) with a specific geographic location. Such "geotagging" stores coordinates within metadata or microformat tags—where machines can find them but people can't. That's where the Geotag Icon comes in. It provides a visual reference to a map link, or if no link is yet made helps viewers recognize the geographic relevance of the content. It's free, easy to use and helps us all visualize the developing semantic web.

Pootle is a user-friendly web portal that makes the translation process so much simpler. It allows online translation, work assignment, gives statistics and allows easy volunteer contribution. You can run Pootle as an Internet server like these projects or run your own copy on an Intranet (for individual work, team work or Translate@thons). Pootle makes use of the Translate Toolkit. Together, these tools are part of our project to make translation easier and of higher quality by creating better tools and user-friendly, central information.

KForge is an open-source (GPL) system for managing software and knowledge projects. It re-uses existing best-of-breed tools such as a versioned storage (subversion), a tracker (trac), and wiki (trac or moinmoin), integrating them with the system’s own facilities (projects, users, permissions etc). KForge also provides a complete web interface for project administration as well a fully-developed plugin system so that new services and features can be easily added.

For this roundup, I stuck to online applications that let you save freeform notes in some sort of organized fashion for later use. I skipped over others that are primarily designed as tools to annotate web pages, such as noteClip, and bookmark managers like del.icio.us, BlueDot, and Chipmark.
