Do you have certain files that you print quite often? Would you prefer to be able to just click on a desktop icon, or a panel icon to print the file? This is so much quicker than opening the file in Open Office, Abiword, or whatever, and then printing it.

Printing from the command line can let you get things done very quickly. It can also open up a world of one-click printing of files, which we’ll get into with a future post. So, to get started, navigate to http://localhost:631 in your browser. If you have a default Ubuntu installation, you should now be looking at your CUPS (formerly Common Unix Printing System) page. I posted about this topic a little while ago, while using Ubuntu 8.04. After my installation of the 64 bit version of Ubuntu 10.04 Lucid Lynx, my keyboard shortcut didn’t function the way I wanted it to. It would unmount any USB flash drive I had plugged in. This wouldn’t do, so here’s how I got it to work again. So, let’s say that you have absolutely no use for the little envelope that is residing next to your volume applet since you installed Lucid Lynx. It is a very useful little guy if you use Evolution, or if you install something like gmail notifier to check your web mail. If not, then here’s how you can remove it. The default theme in Ubuntu 10.04 Lucid Lynx puts the window control buttons (minimize, maximize, & close) on the left side of the title bar. This is really annoying to me, and here’s how you move them back. Well, Ubuntu 10.04 LTS is almost upon us, due for release at the end of this month. This will be the first Long Term Support release since April of 2008’s Hardy Heron. I’ll be upgrading at some point by doing a fresh install. What are your plans? Are you planning to upgrade? Will you upgrade through the Update Manager on your system? Will you do a completely fresh install? If so, how will you backup your data? You may be interested in using something like APTonCD to retain some of your applications, or at least as a listing of them. If you’d like to try out the latest, pre-release version of Lucid Lynx, click here to download. So, let me know what you plan to do in the comments below. I hate it when apps hog too much memory, or cpu cycles. In many cases, if you have an application that’s doing this, there’s an alternative out there that is way leaner. There’s an easy way to determine where to trim the fat. In this example I’m going to be comparing the memory usage of Totem Movie Player, and VLC. These applications play media files, both video and audio. OK, for this test I used a Survivor Man DVD. I played the DVD, and then checked the memory usage of each app once the video began playing. I did each test separately, and repeated a few times to confirm the results, which were very consistent. Oh, I also tested these applications with more than one DVD. Ubuntu has a built in application, Gnome System Monitor, to help you keep tabs on what’s going on with your machine. You can find it in System > Administration > System Monitor. Once you have it open it has a few tabs, displaying various system information. The Resources tab will show you the cpu usage in a percentage, the memory being used, and what’s going on with your internet/network connection. You can customize this to a certain degree. But, do you really want to have to open this thing up every time you want to find out how much memory you’re using. You can add the system monitor to a panel. This will give you information at a glance, without having to open a new program, or stop what you’re currently doing. Here’s what it looks like, and how to do it. I go through a lot of CDs & DVDs, and constantly reaching over to push that little button on the front of the CD/DVD drive is rather annoying. I do not have one of those nifty keyboards that has those media buttons. So, I looked for a way to open and close my drawer from the keyboard, or with the mouse. And I found a few ways to do it. So, do you have a lot of comic books that you want to keep track of? GNOME Comics Organizer can help. This is a little application designed for the purpose of cataloging your comic books. To get it you must first enable the Universe repositories. Here’s how you can do that. Now that that’s done, you can install the app. |
