Fedora Linux version 20 (code name "Heisenbug") has been released and available for download. Fedora Linux is a community-based Linux distribution which is sponsored by Red Hat, Inc. The code name "Heisenbug" is a term for a software bug that seems to disappear or alter its behaviour when one attempts to study it. Fedora is considered as the popular cutting edge distro, behind Ubuntu and Mint Linux for desktop and laptop usage.
The year of Linux on the desktop or living room is here. Today Valve software announced SteamOS, a free Linux-based gaming operating system designed for the TV, DIY enthusiast, and the living room. From the announcement page:
As we've been working on bringing Steam to the living room, we’ve come to the conclusion that the environment best suited to delivering value to customers is an operating system built around Steam itself. SteamOS combines the rock-solid architecture of Linux with a gaming experience built for the big screen. It will be available soon as a free stand-alone operating system for living room machines.
The first-person shooter Half-Life 2 released for Steam on Linux. I truly enjoyed Counter Strike, and I am going to install Half-Life 2 this weekend.

Logstalgia (also known as ApachePong) is a very powerful and handy app. It is a website access log visualization tool. It is an extremely useful tool to give you look at your web server traffic. I often use this kind of software to justify and convince my clients and/or boss that we need more servers to handle traffic. It streams Apache / Lighttpd / Nginx web-server access logs as a pong-like battle between the web server and a never ending torrent of requests.
You can send visitors to different servers based on country of their IP address using Amazon Route 53 cloud based dns server. For example, if you have a server in Amsterdam, a server in America, and a server in Singapore, then you can easily route traffic for visitors in Europe to the Amsterdam server, people in Asia go to the Singapore server and those in the rest of the world be served by the American server. This will results into the various kinds of benefits such as:
- Better performance as you are sending web site visitors to their nearest web server.
- Reduced load on origin.
- Geomarketing/online advertising.
- Restricting content to those geolocated in specific countries (I am not a big fan of DRM).
- In some cases you can get potentially lower costs and more.
In this post, I will explain how to configure and test GeoDNS using AWS Route 53 service.
You can dump Linux or Unix server memory. This is useful for forensics analysis, and testing your own system. This is often desirable to see:
- What code and what data actually resides in memory.
- You can search for specific pids memory.
- Search memory for string and other data such as passwords.
- Works as add-on tool for gdb and others.
- Search/replace/dump memory from running processes and core files.
- All kinds of deep hacking activities that simply saves your time and solve problems.

I usually use GIMP (the "GNU Image Manipulation Program") for editing photos, changing colors, resizing photos, applying significant effects and more. It is a free software alternative to Adobe Photoshop. It is also quite popular with graphics artists and webmasters who wants to edit digital images. GIMP is not just a Linux specific program. It works on all leading operating systems, i.e., Mac OS X, MS-Windows and Unix variants. However, like many other powerful open source software, GIMP can be difficult to master. There are many options and plugins. So if, you are looking to learn or master the GIMP program, give The Book of GIMP a try.
