Aug 05, 2010 GMTSwitching to a lightweight graphical desktop environment is a great way to improve the overall performance of your system, especially if this system happens to be a notebook or netbook. But if you opt, for example, for LXDE, you'll discover that it lacks a graphical tool for managing power profiles and controlling the processor frequency. This might not be a big problem on a desktop machine, but the ability to adjust power settings is crucial for improving the battery life of your mobile companion. The cpufrequtils utility provides a neat solution to this problem. This utility can help you to tweak power management options from the command line. cpufrequtils is available in the software...
Aug 03, 2010 GMTThe humble nano text editor can be a rather handy distraction-free drafting tool, but now and then I need to look up words and their definitions in WordNet. To do that, I tweaked a simple Bash script I stumbled upon on the Stack Overflow Web site. The original script pulls data from the Google Define source, but it took just a few minutes to make it work with WordNet. So if you, like me, need to look up words and their definitions without leaving the terminal, here is a script that can help you with this: #!/bin/bash echo "Enter your word:" read word /usr/bin/curl -s -A 'Mozilla/4.0' 'http://wordnetweb.princeton.edu/perl/webwn?s='$word \ | html2text -ascii -nobs -style...
Jul 27, 2010 GMTWhile the built-in browser on your Android device lets you bookmark interesting and useful links, you'd usually want to save them on a Web-based service rather than storing them on the mobile device. There are several utilities that can help you with that. InstaFetch, for example, lets you bookmark the currently viewed Web page on the Instapaper service, and there is a plethora of utilities that can bookmark pages on your Delicious account.But what if you want to push links directly from your Android device to a desktop browser? android2cloud is a nifty open source solution that allows you to do just that. Using it, you can push links from your Android device directly to the Google Chrome...
Jul 22, 2010 GMTWhen it comes to filers and pilers, I firmly belong to the latter category. I do like to keep all my disparate data -- notes, links, to-dos, etc. -- in one application, so when I need to find something, I have to look in one place. That's why I wrote a simple Python command-line tool that acts as my personal data manager. While there are many open source applications out there that provide this type of functionality, none of them scratch my particular itches. So I wrote my dead-simple script that does pretty much anything I need. The first version of Pygmynote was released in August 2008, followed by a major update in January 2009. A few days ago, I released version 0.5.1 which fixes a...
Jul 19, 2010 GMTThe default battery applet in Gnome is fine for basic use, but if you are looking for something more powerful, try the Battery Status applet. Once installed, the applet provides more detailed information about the battery, and you can specify what additional data the applet's icon should display. For example, you can display the estimated remaining time, so you can save yourself a couple of mouse clicks. In addition to that, the Battery Status applet offers other useful features such as the ability to switch between different power modes. By enabling the session actions (Show | Session Actions), you can also use the applet to shut down and restart your machine, and you can put it into the...
Jul 15, 2010 GMTdigiKam is undoubtedly a powerful application for processing and managing your photos, but there are situations when you need something lighter. For example, I use my netbook when I'm on the move to off load photos from my camera and quickly go through them. For this, I use Geeqie, a lightweight image viewer that offers a slew of nifty features that make it an indispensable tool in my arsenal. For starters, Geeqie is lightning fast, and its streamlined interface suits small screens perfectly. The application supports RAW files out of the box, courtesy of the UFRaw software. Better yet, Geeqie can batch convert RAW...
Jul 02, 2010 GMTOne of the major selling points of Eee PC netbooks is their impressive battery life which is achieved by utilizing the Asus Super Hybrid Engine (SHE) technology. While it's designed to work under Windows, you can take advantage of this technology if you're running a Linux distro on your Eee PC, courtesy of the Jupiter utility. Although this tool is designed primarily for Eee PC netbooks, it works well on pretty much any notebook. So if you want to squeeze as much battery life from your machine as you can, Jupiter is worth a try. Jupiter's Web site provides DEB and RPM binary packages, so you can easily install the...
