If you are looking to upgrade the memory in your Linux PC, you are probably wondering how many open slots you have, what type of memory is already installed, and what you need to buy for an upgrade… without having to open your computer.

One of the nicest things about Linux is the variety and number of distributions available for people to use. This week we want to know which Linux system is your favorite.
Linux Mint has released a new version that is based on Debian Linux instead of Ubuntu, which is also based off Debian. This means faster releases and better hardware support.
The upcoming release of Ubuntu, scheduled for final release in October, will bring some new interface improvements including a different Netbook edition.
Virtually all linux distributions include sendmail as the default MTA. Which is okay – it has been around for a long time, is stable and it works great (although the postfix afficionados might disagree!). But it has nothing built in for spam control which is good; it was not designed for that. So you’ve installed spamassassin and it works good but you still are getting unflagged spam emails through. Perhaps you need to try greylisting.
If you are tired of trying to keep up with Apple’s new iPod releases, upgrade your old iPod for free with Rockbox. Rockbox allows you to upgrade your aging iPod with new themes, fonts, games, and more.
When you’re running production servers, the one thing you don’t want to do is upgrade the kernel every time a new update comes out. Why? Because that’s the only Linux update operation that requires a reboot once it’s done—and in a production environment you often can’t have downtime.
If you’ve worked in the admin world for any length of time, you’ve probably run into an instance where you needed to change the hostnames on your server to match some corporate naming standard, but you can’t have downtime either. So how do you change the hostname without rebooting?
If you have been an admin for any length of time, you have certainly discovered situations where a server spikes in CPU use or memory utilization and/or load levels. Running `top` won’t always give you the answer, either. So how do you find those sneaky processes that are chewing up your system resources to be able to kill ’em?
Linux distributions like Ubuntu open the main menu with Alt+F1 instead of the Windows key that most new Linux users would be expecting, but it used to be simple to change the shortcut key. Since Ubuntu 9.10 the process isn’t so obvious, but we’ve got the instructions for you.
If you are looking for something to freshen up your desktop then Ubuntu 10.10 has seventeen beautiful new wallpapers to choose from.
We’ve already shown you how to customize shortcut keys in any Linux application, but for today’s lesson we’ll take it a step beyond—and assign a shortcut key that switches an open application to be the currently focused window.
Ubuntu has an easy way to keep your system clock synchronized with the internet time servers, but sadly it’s not enabled by default. Here’s the quick steps required to enable it for your system.
With Gmail adding the ability to make free calls within the US and Canada, now is a great time to invest in a quality computer microphone. We’ll take some of the guesswork out of that process, and give you some tips on setting up your microphone once you get it.
One of the more annoying problems with Linux has always been the lack of AutoHotkey support, so you couldn’t customize your shortcut keys—but now with the open source application AutoKey, you can do that and more.
Google’s own Matt Cutts has the answer on how to easily switch back and forth between the Dev and Beta channel versions of Google Chrome if you’re using a Debian-based Linux like Ubuntu. Here you go:
If you’ve got a whole folder of .flac files that you want to convert into MP3 files instead, you can do so with a simple command from the terminal—or if you’re using Windows, from a cygwin prompt.
Over at the Atomic Spin weblog, they’ve written up an interesting tip that uses grep to recover files. Here’s the brief command you’d use, but hit the link for the full explanation.
With Ubuntu 10.10 (the Maverick Meerkat), users and developers will have an end-to-end touch-screen framework — from the kernel all the way through to applications. Our multi-touch team has worked closely with the Linux ker...
If you spend loads of time at the command line on your Linux, Mac, or Cygwin terminal, here’s the simple trick to view stock quotes from the command line.
Just like Windows 7 and OS X, Ubuntu has the ability to create a slideshow wallpaper thanks to GNOME 2.28. Here is how you can take control of your wallpaper slideshows with a simple to use GUI tool or a down and dirty text editor.
Do you have an older PC or laptop laying around just collecting dust and not sure what to do with it? You could sell it, but not get much for it. Here we bring you a guide on how to bring it back to life.
We all love to download stuff from the internet, and there are heaps of great download manager tools that we can use to schedule our downloads. It might just be easier to use a download manager, but there is no harm in exploring the tools that already comes with our Ubuntu and make the full use of it.
