The linux kernel is, among other things, something that gets updated periodically when you update your system. When this happens, the kernel that’s being replaced is not deleted, it’s left on your system, but just not used anymore. For example, as I write this, I’m using the 2.6.24-24 kernel. My system may still contain older versions, like 2.6.24-23, or 2.6.24-19, etc. I no longer need these older versions, and they are taking up space on my hard drive. Removing these older versions will free up some hard drive space. The first thing you need to do is find out which kernel you’re currently using, so that you don’t delete it.

Computerbank Victoria of West Melbourne, Australia, is a not for profit organization staffed by volunteers, who strive to bring computers to those in need. They’re using Ubuntu 9.04 on the machines they handle. Here is what they do…
Ubuntu 10.04, codenamed Lucid Lynx, will be available in April of 2010. This will be the 12th Ubuntu release to date, and they’ve got some lofty goals for it. The developers are striving for a lean and fast creature with this next LTS release. Some of what they’re aiming for… Well, here’s the new site, I hope you like it. This new arrangement will give me more freedom with the site and it’s content. New PostsI’ve been taking a break from posting any new material for a while now. However, new posts will be following this move to the new site, so stay tuned! Some of the subjects I’ll cover…
Let’s say you’re logged into your Ubuntu machine as an unprivileged user, meaning that you don’t have permission to use the sudo command on the command line. As such, you cannot update the system, install a program, or perform other tasks in the terminal that require the sudo command without logging out and then back in as the administrative user, or using the User Switcher. This annoys me. So, how do I execute commands in the terminal that require the sudo command while still logged in as the unprivileged user?? Have you ever asked yourself, “How do I find out exactly which version, or release, of Ubunut I have?” There are a few ways of doing this. The easiest, and most basic, is to open the System Monitor.You do this by going to System > Administration > System Monitor. You then click on the System tab. There you’ll see which version of Ubuntu you’re using, along with your linux kernel, and which version of gnome you have. However, this information can be incomplete. For example, if I do this, I’m told that I have Ubuntu 8.04. Well, I do, but there’s more to it than that. You’ve heard of Microsoft’s new operating system, Windows 7. Mark Shuttleworth, founder of Ubuntu, shared his thoughts on the new version of Windows with the UK’s Register. Here’s an excerpt…
Read the whole story here. A new version of Ubuntu is released every 6 months, and it’s very easy to upgrade. All you have to do is click a button or two in your update manager and there you have it. You’ve just gone from Ubuntu 8.04 to Ubuntu 8.10! Is this something that you should be doing?? You could upgrade every six months, or you could upgrade every 2 years. Which would you prefer?? I’ve chosen to upgrade every 2 years. Here’s why… This could be very useful to you if you’re working in the terminal and need to step away for a moment. You can achieve a locked screen, just like when you do it the graphical way, with this command entered at the command line, or cli… In Ubuntu you can have the appointments in your calender appear in your desktop calender/clock. If you’ve just come over from years of Microsoft Windows use, Evolution is the linux equivalent of Outlook. Ubuntu works with the Evolution mail client to give you quick access to your appointments and tasks right on the desktop, without having to open your email program. Here’s how it works… |
