The Coming HTML 5 Revolution in Linux

Up

Down

I have spent the last couple of weeks working on a very ambitious C++ program. The program is a software model of a mechanical engineering system. I have never undertaken a more challenging or more rewarding computer programming project. As I spent hour after hour poring over the code, I began to realize why everyone is making such a fuss about HTML 5. read more...

Basic nginx Configuration

Up
vote
Down

nginx is a powerful and modern HTTP server. It is perhaps most commonly used as a reverse proxy, also known as a load balancer or front end proxy. It follows the UNIX philosophy of doing one thing, and doing it well, and as such, it relies on several helper daemons to become a full-featured web server such as Apache. For example, to serve PHP, it relies on php-fpm to do the processing, while nginx itself handles the caching and speaking the HTTP protocol itself. In this article, we will talk about common configuration options, and how they relate to it's performance. We'll also discuss some basic administrative tasks. read more...

Using Git for Source Control

Up
vote
Down

GIT is the source control tool, a distributed version control system (dvcs) which is written in C. This provides a history of the files that are maintained by it. In distributed version control each user has a complete copy of the code so there is no central code repository. In this scenario an administrator makes changes, adds them to the index (called staging) and then adds them to the repository (called commit). Git will take this information and maintain a version history that users can track. This is all performed locally but could be synchronized with a remote repository. read more...

Unix signals list

Up
vote
Down

Processes are required to respond to signals sent to them. This is one way a user can communicate with signals and control them.
Signals are asynchronous events that can occur to a running process and may be caused by hardware, software or users. Signals are numeric integer messages that have been predefined so they understand what these signals mean. When a process receives a signal, that process must respond to the signal. Uncaught signals will cause default actions to take place, which often means the process is terminated. If you use “kill -l”, or “trap -l” you can get a list of available signals:

Configure iSCSI and iSNS Servers

Up
vote
Down

In previous tutorials we've learned SUSE has made life very easy for System Administrators having developed graphical tools to manage many system components including the iSCSI target. As with most things in life there is a price to pay for this ease: YaST only writes to the configuration files and the changes do not come into force until the service is restarted. Command Line knowledge lifts us out of troublesome pit and gives us full control of our systems. Additionally we will add in ISNS (Internet Storage Name Service) to locate ISCSI Targets on our network. read more...

CentOS 6 Minimal Desktop Install

Up
vote
Down

This example of a minimal desktop shows how to manually create partitions using ext3 and ext4 for a server that has a minimal desktop for a graphical interface.
Create a / partition with the ext4 file system. The size of this partition should be at least 6 GB for a minimal install. One aspect to think about, if you are using the standard partitions you will not be able to resize these later as you would if you were using LVM. 10 GB is a safe choice for a server if you are creating a separate /usr partition.
