Ease the Transition to Ubuntu with a Cheat Sheet
10:00PM Kevin Purdy | The open-source-friendly folks at the FOSSwire blog have posted a PDF “Ubuntu Cheat Sheet,” covering the basic terminal commands one might have to use and, just as importantly, naming important programs and packages so you don’t end up deleting or messing with something that’ll cause headaches down the line. WIth the release of Hardy Heron one day away, adventurous newcomers might want to keep FOSSwire’s cheat sheet printed and handy for reference. Ubuntu Cheat Sheet [FOSSwire] More »
Create a Local Website Mirror with Wget
12:00AM Kevin Purdy | Most relatively new Linux users might have used the wget command a few times while installing packages or grabbing specific files, but the little command word can be a pretty powerful tool. The FOSSwire open source blog points out how you can use wget to mirror a website, either one page at a time or with all the internal links available for offline browsing. As noted, however, grabbing large, multi-page sites can be a serious drain on bandwith (both yours and the site’s), so adding a delay option is both considerate and wise.

2:00AM Kevin Purdy | Many, if not most, of the newest and updated Linux applications out there are crafting Ubuntu/Debian-ready .deb packages that require just a double-click to install, but many apps are still available only in the .rpm files used by Red Hat and Fedora-based distributions. The Ubuntu Unleashed blog has a quick and simple tutorial on installing the Alien conversion tool and using it to convert packages to .deb format. Once you’ve got Alien installed, the command is simply: sudo alien -k name-of-rpm-file.rpm Note that this won’t work for programs that are designed to utilise specific Red Hat/Fedora functions, but will save you a good deal of digging for alternate files.

Learn the Basics of Installing From Source in Linux
2:45AM Kevin Purdy | Few things can be as frustrating to non-expert Linux users as seeing the phrase “… or compile from source packages” on the download page of that killer app to try out (and we know that’s often the case for you patient non-Ubuntu users out there). If you’re looking for a nuts-and-bolts guide to installing software from those strange-looking Whatever.tar.gz files, Tuxfiles.org has a pretty good one. While the link takes you through the unpacking, compiling, installing, and cleaning up, there’s a basic command line method for almost any package (replacing “package” with the appropriate downloaded file name): More »
Get Started with Webcams in Linux
1:30AM Kevin Purdy | Modern Linux systems have advanced to the point of supporting (in one way or another) most kinds of essential computer hardware—it’s the peripherals that cause the vast majority of headaches. But thanks to some helpful community hackers, a wide array of webcams, from cheap to professional, can be implemented in the open-source operating system. Carla Schroder, author of The Linux Cookbook, offers a great guide for anyone trying to get their webcam set up and usable in Linux, including suggestions for software and how to find out what your distro has named your webcam. There’s a part two around the corner, according to the guide, with likely more advanced tips and tricks. Photo by ThenAndAgain.

2:30AM Kevin Purdy | If you like to have ready-to-go access to remote machines (or a home server, perhaps) from your Linux desktop, you might have noticed that you can’t always get what you want. Many home and office routers kill “idle” connections after a certain length of time, forcing you to log in again. The FOSSwire blog points out a one-line addition to the end of the client’s SSH configuration file (found at /etc/ssh/sshd_config in many systems) to fix this: ServerAliveInterval 180 That should send a little ping out every three minutes to ensure the connection is kept alive. This tip should work on most any OpenSSH server that allows access to its sshd_config file, but, as FOSSwire points out, it means any connections you leave open are just that—open to any nefarious passer-by, so use session-closing caution when needed.

Add New Document Templates to GNOME’s Right-Click Menu
1:30AM Kevin Purdy | Tired of seeing just an “Empty file” option when you right-click to create a new document on your Linux desktop? In GNOME-based systems, the key to expanding your options lies in the “Templates” directory inside your home folder, according to the Tombuntu blog. Simply open a program you want to have available for right-click creation, save a blank file with the name you want to see in the menu (like “Text file” or “New GIMP image,” for instance), and save it in the Templates folder. In my case, I ended up with a bunch of working templates but generic file icons, so I went in and manually changed them to reflect their opening programs. It’s just another step in making your Linux desktop a familiar one, but it’s also a decent time saver. Add Your Document Templates to GNOME [Tombuntu] More »
Arrange the Window Buttons in GNOME
2:00AM Kevin Purdy | Want to rearrange the window-top buttons in your GNOME-based Linux system? The FOSSwire blog shows how to put your titlebar in any order you please, using the ever-helpful gconf-editor tool. Launch the editor, browse through the folder trees to Apps->Metacity->General, then find “button_layout” in the right-hand pane. Double-clicking on the “Value” field lets you rearrange (or remove) the four known buttons on either side of the windows (separated by a colon), so you can get Mac-style left-focused buttons, a minimalist menu-only look, or anything else you’d like. If you mess up too badly, you can right-click the button_layout item and “Unset” to restore its default values. Hit the link below for more guidance on using gconf-editor and tweaking the window settings. Customize your Titlebar [FOSSwire] More »
Group Windows on the Taskbar in Ubuntu/GNOME
2:30AM Kevin Purdy | How-to blog Tech-Recipes.com offers a useful desktop optimisng tip for Ubuntu/GNOME newcomers (and those of us who forgot it was there). The bottom taskbar installed in Ubuntu and most GNOME-based desktops can group application windows together in a fashion similar to XP. To make it do so, right-click on the dotted section just to the left of your “Windows List” section (in Ubuntu, that’s between the “Show Desktop” button and the window buttons). Select “Preferences,” and then choose either “Group windows when space is limited” or “Always group windows.” Nifty tip, and not so easy to find.
