A Long Weekend Project: Linux Filesystem Tune-up

A Long Weekend Project: Linux Filesystem Tune-up

If the thought of getting up at early and dragging yourself across town to stand in line for sales doesn't fill you with the holiday spirit, why not spend your weekend doing something more meaningful, like cleaning up your Linux filesystems? To be sure, a modern Linux file server probably isn't in need of being torn down and rebuilt, but if [...]

The State of Linux Audio: Dec 2010

The State of Linux Audio: Dec 2010

In my case. Applications -> ALSA -> Sound. Sound is something I never had any problems. The only configuration I had to make was choosing the right sound card in the kernel configuration.

10 Cool Nmap Tricks and Techniques

Nmap (“Network Mapper”) is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.

Redhat Enterprise Linux 6 available

Redhat Enterprise Linux 6 available

CentOS 6 should be out in about a month or so, if it goes like past releases. Red Hat Enterprise Linux is an enterprise platform well-suited for a broad range of applications across the IT infrastructure. The latest release, Red Hat Enterprise Linux 6, represents a new standard for Red Hat by offering greater flexibility, efficiency, and [...]

Future Ubuntu Releases Will be Shipped With LibreOffice, Says Mark Shuttleworth

Future Ubuntu Releases Will be Shipped With LibreOffice, Says Mark Shuttleworth

OpenOffice's future was doomed from the day when Oracle acquired SUN Microsystems. The eventuality became even more obvious when they pulled the plug on OpenSolaris. Thankfully, OpenOffice is an open source software and leading contributors of the original project has forked OpenOffice and the new project will be called LibreOffice. [...]

Microsoft using anti-Linux tactic against Google’s Android

Microsoft using anti-Linux tactic against Google’s Android

The lawsuit Microsoft filed against Motorola and its use of Google's Android phone software is awfully familiar. Microsoft used the same tactic against Linux when the open-source software reached critical mass in the data center and threatened to derail the growth of Microsoft's server business seven years ago. After name-calling failed to [...]

Direct3D 10/11 Is Now Natively Implemented On Linux

Direct3D 10/11 Is Now Natively Implemented On Linux

It's a pity Luca Barbieri or any Mesa / Gallium3D developers are not at Oktoberfest as they are deserving of more than a few Maß of Augustiner. In fact, today a new Gallium3D state tracker was pushed into Mesa and it's perhaps the most interesting state tracker for this open-source graphics driver architecture yet. It's a state tracker that [...]

Why PulseAudio?

Why PulseAudio?

PulseAudio has been on the receiving end of quite a bit of flaming. Some deserved, a lot not. Most critics have been appeased as PulseAudio has matured and distros make setup smoother, but there are still a number of troll users who trash it at every opportunity. Common objections to PulseAudio includes: “We don’t need another sound [...]

W7 Theme for Ubuntu brings Windows 7’s familiar GUI to Linux

W7 Theme for Ubuntu brings Windows 7’s familiar GUI to Linux

W7 is a tool that changes your Linux GUI to a more familiar Windows interface. Linux has a highly configurable GUI, but if you long for the more well-known Windows interface, this script will do a remarkably good job of making Ubuntu look like Windows 7. You can download either a GNOME and KDE version, as well as one of a few Firefox themes [...]

HOWTO: Block brute force attacks on your SSH server

HOWTO: Block brute force attacks on your SSH server

You have probably seen very simple iptables rules to do this. This is a little bit better. -A INPUT -i eth0 -p tcp -m tcp --dport 22 -m state --state NEW -m recent --set --name SSH --rsource -A INPUT -i eth0 -p tcp -m tcp --dport 22 -m recent --rcheck --seconds 30 --hitcount 4 --rttl --name SSH --rsource -j REJECT --reject-with tcp-reset -A [...]

HOWTO: Create a shell script to monitor load average on a Linux server

HOWTO: Create a shell script to monitor load average on a Linux server

Load Average on a server reflects the current state of the server. Higher the load average, poorer is the server performance hence it is a necessity to monitor the load average on the server. The following shell script monitors the load average on the Linux server and inform the server administrator with the current running processes of the server [...]

Linux is winning

Linux is winning

Good article, but to be honest, most people have no idea Android is based on Linux or is Open Source at all. So its not like the general public is choosing Linux over other platforms on purpose, its because to them Android can do more than the iPhone and iPad OS. As for the video codecs, its more nerd stuff that the general public wont care [...]

HOWTO: Move your logs and temp files to RAM

HOWTO: Move your logs and temp files to RAM

While working with netbooks and other portable computers over the years I have always looked for new ways to improve battery life, but I have also been concerned with maximizing performance of these small systems. Today I would like to share with you a simple trick to improve performance and the overall "feel" of your computer. To improve [...]

UK Officials: Dump Microsoft and Use Linux to Save Money

UK Officials: Dump Microsoft and Use Linux to Save Money

Although they say this every year or so, it never happens. It's just so they can get Microsoft to give them a nice fat discount when they need to upgrade. You could say that it's a cost-cutting measure in itself. "In terms of spending less, what about migrating the whole of government (the NHS, education etc.) from Microsoft products to Linux [...]

Novell Wins!

Novell Wins!

Someone needs to do a "Here's all the things that came out while Duke Nukem Forever was in development" time-line for this. I'm fairly sure a good portion of my IT career fits in that scope. Here you go, munchkins. Judge Ted Stewart has ruled for Novell and against SCO. Novell's claim for declaratory judgment is granted; SCO's claims for [...]

Adobe discontinues (beta) 64-bit Flash support for Linux

Adobe discontinues (beta) 64-bit Flash support for Linux

With Flash 10.1 release, Adobe discontinues (beta) 64-bit Flash support for Linux. Unusable nspluginwrapper or a 32-bit browser is all what is left. Sadly this is both endemic of Adobe and Linux. Adobe makes crap that doesn't work on anything outside of Windows just barely and Linux is left at the behest of the development community as far as [...]

HOWTO: Linux SAN Multipathing

HOWTO: Linux SAN Multipathing

There are a lot of SAN multipathing solutions on Linux at the moment. Two of them are discussed in this blog. The first one is device mapper multipathing that is a failover and load balancing solution with a lot of configuration options. The second one (mdadm multipathing) is just a fail-over solution with manual re-enable of a failed path. [...]

Google to employees: “Mac or Linux… but no more Windows”

Google to employees: “Mac or Linux… but no more Windows”

We first heard rumors of this policy change a couple of months ago, but now it's made the papers: the Financial Times is reporting that Google is phasing out the use of Windows internally, as employees are migrated to either Linux or Mac OS X on machine turnovers or new hires. The policy change was precipitated in large part by the security breach [...]

Ubuntu To Pull In New Versions Of Firefox

Ubuntu To Pull In New Versions Of Firefox

Ubuntu's longstanding policy of not pulling in new major versions of packages into their stable repositories is facing a slight change. Canonical along with the Ubuntu development community have been making it easier to deploy Mozilla Firefox web-browser updates into existing Ubuntu releases. Rather than dealing with back-porting security [...]

HOWTO: Add a progress bar to Linux shell commands

HOWTO: Add a progress bar to Linux shell commands

How many times have you wished there was an easy way to view the progress of a gzip? a grep? redirected file read/writes? file copies? There are many situations where the addition of a simple progress bar would make the user experience 1 million times more bearable. Several years ago I had read about pipe viewer, or pv for short. This is truly the [...]
