All Internet content carries a risk. Content Filtering helps companies and home users to stop unwanted data. It is used as part of Internet Firewalls or Proxy Servers to screen the content of all incoming Internet traffic. Content filtering usually works by specifying character strings that, if matched, indicate undesirable content that is to be screened out.

A process is a fundamental part of any operating system - irrespective of whether they are proprietary or Free. And all Operating systems usually have a lot of processes running at any given time. This begs the question, what exactly is a process ?

Linux clusters vs. grids

Filed under
HowTos

When most people think of Linux clusters, they think they are used for load-balancing purposes only. Yet, that's not the only functionality that makes Linux clusters on par with mainframes or high-end, mid-range Unix servers for many jobs. In this tip, I'll examine Linux cluster options and similar server approaches, like grid computing.

Matching databases to Linux distros

Relational database management systems (RDBMSs) aren’t the sort of thing to get most folk out of bed in the morning – unless, of course, you happen to think they’re one of the most brilliant concepts ever dreamed up. These days you can’t sneeze without someone turning it into a table value in a database somewhere - and in combination with the freely available Linux operating system, there’s no end to them. Most Linux distros make it almost trivial to add popular DBMSs to your system, such as MySQL and MariaDB, by bundling them in for free in their online app stores. But how do you tell which combination - which Linux distro and which DBMS - will give you the best performance? This week we've revved up the Labs servers to ask the question: what level of performance do you get from OS repository-sourced DBMSs? Read more

The Curious Case of Raspberry Pi Consumerism

I find the attitude of many within the Raspberry Pi community to be strange and offensive. I first discovered this odd phenomenon (odd because it contradicts the ethos of the project's academic foundations) back when it first started, as many within the Raspberry Pi community took an extremely hostile attitude toward academic freedom, apparently in defence of various parties' highly dubious intellectual monopolies (Broadcom and MPEG-LA, for example). I pointed out the irony and hypocrisy of their attitude at the time, explaining that they were more than happy to leech Free (as in freedom) Software for their own benefit, but then balked at the prospect of freely sharing the results, and in particular this contradicted their stated academic goal of facilitating better computer education in UK schools, an environment that rightly demands open access to knowledge.

Google Chrome 38 Beta Brings New Guest Mode and Easier Incognito Mode Switching

The developers have explained that the user switching feature has been redesigned and it will make changing profiles and into the incognito mode a lot simple. They have also added a new experimental Guest mode, a new experimental UI for Chrome supervised users has been implemented, and numerous under-the-hood changes have been made for stability and performance. "This release adds support for the new element thanks to the hard work of community contributor Yoav Weiss, who was able to dedicate his time to implementing this feature in multiple rendering engines because of a successful crowd-funding campaign that raised more than 50% of its funding goal."

PfSense 2.1.5 Is a Free and Powerful FreeBSD-Based Firewall Operating System

PfSense is a free network firewall distribution based on the FreeBSD, it comes with a custom kernel, and a few quite powerful applications that should make its users’ life a lot easier. Most of the firewall distros are Linux-based, but PfSense is a little bit different and is using FreeBSD. Regular users won't feel anything out of the ordinary, but it's an interesting choice for the base. The developers of PfSense are also saying that their distro has been successful in replacing a number of commercial firewalls such as Check Point, Cisco PIX, Cisco ASA, Juniper, Sonicwall, Netgear, Watchguard, Astar, and others.
