Clean Up Ubuntu Grub Boot Menu After Upgrades

One of the things in Ubuntu that has always driven me crazy is the addition of new items into the grub menu without removing the old entries that likely don’t even work anymore. I’m sure most experienced Ubuntu users already know how to do this, but here’s the method anyway.

Linux Tip: How to Tell if Your Processor Supports VT

Virtualization Technology (VT) is a set of enhancements to newer processors that improve performance for running a virtual machine by offloading some of the work to the new cpu extensions. Both AMD and Intel have processors that support this technology, but how do you tell if your system can handle it?

Make Grub Bootloader Wait Indefinitely for OS Selection

If you are doing a lot of testing of different builds, there’s nothing more annoying than rebooting and then having the system boot into the wrong choice on the grub menu before you have a chance to pick the one you want. Reader Victor wrote in with this tip: You can just comment out the timeout line entirely to stop grub from picking anything, giving you time to get your morning coffee.

Disable ProFTP on CentOS

I realize this is probably only relevant to about 3 of the readers, but I’m posting this so I don’t forget how to do it myself! In my efforts to ban the completely insecure FTP protocol from my life entirely, I’ve decided to disable the FTP service running on the How-To Geek server, which is running the CentOS operating system.

Shell Geek: Rename Multiple Files At Once

Let’s say you have a directory with hundreds of files with the wrong file names, and you’d like to replace every filename containing test with prod. (this is a contrived example). We can easily do this with the “for” command in bash, combined with a little bit of bash goodness. Today we’ll learn how to replace text in a variable in a for loop.

Fixing Problems with Slow Katapult Searching

If you’ve become addicted to using keyboard launchers like I have, you might have encountered the scenario where Katapult became extremely slow for no apparent reason. The problem is most likely because you’ve got a big music library in Amarok, and Katapult starts searching your music library by default after you type a single character.

Install Tabbed File Manager in Ubuntu

One of the greatest mysteries to me is why most file managers don’t have tabs – it makes performing tasks so much simpler. I’ve found a lightweight file manager for Ubuntu called PCMan that gives you most of the functionality from Nautilus, but also has tabs.

Trillian Astra V4.0a Including Screenshots

I have begun Alpha testing on Cerulean Studios Trillian Astra the new version of the Trillian IM client. I thought I would share with you the look and feel of this new application as it goes through development. Remember, this is still in Alpha testing.

Disable Single-Click Opening of Files in KDE

Having switched from Ubuntu to Kubuntu recently, the first thing that irritated me beyond all reason was that single-clicking on a file or folder immediately opens the file instead of selecting it. Since I use Windows and Ubuntu on a daily basis, it’s just frustrating that it works differently in KDE.

Access Your MySQL Server Remotely Over SSH

So you’ve got MySQL on your web server, but it’s only opened to local ports by default for security reasons. If you want to access your database from a client tool like the MySQL Query Browser, normally you’d have to open up access from your local IP address… but that’s not nearly as secure.

Clear History from Totem Movie Player in Ubuntu

If you’ve been using the default movie player in Ubuntu to play videos, you might have noticed that there’s no way in the application to clear the recent history of watched movies. This could cause issues if you happened to open a video that you don’t want other people to see in your list.

Keyboard Ninja: Launch any Application Without the Mouse

Don’t get me wrong, I think the mouse was probably the greatest innovation in computing since the silicon chip, but for a power user it’s really the slowest form of input.  Taking your hands off the keyboard to reach for your mouse takes easily 500 ms of time, if you’re fast.  Add to that the time to actually find the cursor (no small feat on high resolution screens), and the time to find and click on that one tiny icon you need, and you’re talking some serious productivity cramping.  Of course, you could always be one of those *nix rebels who refuse to use any graphical environment, but what’s the fun of using bash, VI and command-line compilers for the rest of your days?

Why is Amarok’s "Burn This Album" Disabled in Ubuntu?

So you are using the killer Amarok music application under Ubuntu, but when you try  to “Burn this Album”, the menu item is grayed out and otherwise disabled. The reason for this is because Amarok is a KDE application designed to work with K3b, the cd burning application for KDE, but it’s not installed by default in Ubuntu. (For that matter, neither is Amarok)

Linux QuickTip: Downloading and Un-tarring in One Step

Most of the time, when I download something it’s a file archive of some kind – usually a tarball or a zip file. This could be some source code for an app that isn’t included in Gentoo’s Portage tree, some documentation for an internal corporate app, or even something as mundane as a new WordPress installation.
