….. Although forum software often is reasonable, it doesn’t make me go, “wow”. ….. So, it shouldn’t come as a surprise that when Jeff Atwood, cofounder of Stack Exchange and the author of the famous “Coding Horror” blog, announced he was going to make better Web-based forum software, I personally reacted with a shrug. After all, I’ve used and seen forum software for years. How much different or better could it be?
Well, I can report to you that even though Discourse, Atwood’s open-source forum software, is still somewhat unfinished, it already is head and shoulders above other forums I have used, as both a user and an administrator. The fact that it is open source, based on Ruby, PostgreSQL and Ember.js is icing on the cake, making what already was excellent software even better. …..

In Ubuntu/Debian by default while creating ext2/ext3/ext4 file system 5% of disk space is reserved for super user across each partition.
Except for root partition 5% reserved space is not required for other partitions. So we reuse that reserved space.

A Linux Foundation Certified System Administrator (LFCS) has the expertise to do basic to intermediate system administration from the command-line for systems running Linux. Linux Foundation Certified System Administrators are knowledgeable in the operational support of Linux systems and services. They are responsible for first line troubleshooting and analysis, and choose when to raise issues to engineering teams.
The series will be titled Preparation for the LFCS (Linux Foundation Certified Sysadmin) Parts 1 through 10 and cover the following topics for Ubuntu, CentOS, and openSUSE:
Part 1: How to use GNU ‘sed’ Command to Create, Edit, and Manipulate files in Linux
Note: This article also touches on the use of several other commands used for processing text streams in Linux, such as uniq, sort, grep, tr, and cut.

SSH (Secure SHELL) is one of the most used network protocol to connect and login to remote Linux servers, due to its increased security provided by its cryptographic secure channel established for data flow over insecure networks and its Public Key Authentication.
While using passwords to login to remote servers can provide a less secure to system security, because a password can be brute-force cracked, SSH Public Key Authentication provides the best secure method to perform distance logins, because it’s almost impossible to decipher the key and the private key guarantees that the sender it’s always who it claims to be.
This article will show you how you can generate and use SSH Keys from Windows based platforms using Putty client to automatically perform remote logins on Linux servers without the need to enter passwords.

If you are a Linux or Unix user, I am sure you will miss the terminal (and all the wonderful things you can do with command lines) in a Windows environment. Most of the time you won’t need to use the command prompt in Windows, and its user-interface is not as friendly either. However, if you have the need to use a terminal, Cygwin is the best tool for you. Let us see how to install and configure Cygwin in the Windows environment.

Wine is a free and open source application that aims to allow applications designed for Microsoft Windows to run on Unix-like operating systems. Wine also provides a software library, known as Winelib, against which developers can compile Windows applications to help port them to Unix-like systems.
Wine is a compatibility layer. It duplicates functions of Windows by providing alternative implementations of the DLLs that Windows programs call and a process to substitute for the Windows NT kernel. This method of duplication differs from other methods that might also be considered emulation, where Windows programs run in a virtual machine. In this article we are installing wine 1.7.25 version on Ubuntu 14.04.

After H.264 came H.265. It also has a few other names, most commonly High Efficiency Video Coding (HEVC) or MPEG-H. H.265 doubles the data compression ratio compared to H.264 and can support resolutions up to 8192×4320. This means that video at the same quality needs only half of the bandwidth (or file size). Alternately, it means that the quality of the video can be substantially improved at the same bit rate, something very important for very high definition (i.e. 4K and 8K) displays.
