Cheat: Cheatsheets for Command-Line Tools

Sep 30, 2013 GMT

Most command-line tools on Linux come with documentation accessible through the man command. But scrolling up and down the help file trying to figure out how to make a tool do what you want is not always the most efficient way to go. Enter Cheat, a simple Python-based tool that allows you to access cheatsheets for command-line tools. Once installed, the cheat command followed by the name of a specific tool returns a concise usage guide. Type, for example, cheat tar, and you should see a list of the most useful tar options and their usage. Installing cheat is a rather straightforward affair. First, clone the project's GiHub repository: ...

Quick Directory Navigation from the Command Line

Aug 24, 2013 GMT

Jeroen Janssens has recently shared a neat little hack that allows you to bookmark often-used directory paths in the terminal and quickly jump to any of the bookmarked directories. The way the hack works is simple: several custom functions in the .bashrc file are used to create and remove symbolic links in the ~/.marks directory as well as quickly jump to a specific bookmarks. So to make the hack work on your system, add the following code to the ./bashrc file: export MARKPATH=$HOME/.marks function jump { cd -P "$MARKPATH/$1" 2>/dev/null || echo "No such mark: $1" } function mark { mkdir -p "$MARKPATH"; ln -s "$(pwd)"...
Set up Your Own Firefox Sync Server with Weave Minimal

Aug 19, 2013 GMT

Using the Sync feature in Firefox, you can keep browser data in sync between different devices and platforms. By default, Firefox syncs data using the service maintained by Mozilla, but it's easy to set up your own synchronization server courtesy of the Weave Minimal software. First of all, make sure that the Python setuptools package is installed on your system. On Debian and Ubuntu-based distibutions, the package can be installed by running the apt-get install python-setuptools command as root. Once you've done that, run the easy_install -U weave-minimal as root to install the Weave Minimal server. You can then run the server using the weave-minimal --enable-registration command.Next...
Change Default Search Engine in Firefox for Android

Aug 15, 2013 GMT

I've been using Ixquick as my primary search engine lately, and I'm pretty happy with it so far. In fact, I like it so much that I decided to set it as the default search engine on Firefox for Android. It turned out, though, that this is not as straightforward as I expected. Here is how this can be done. In Firefox for Android, navigate to https://addons.mozilla.org/android, search for ixquick, and install the Ixquick HTTPS Privacy Search Engine add-on in the usual manner. Once you've done that, tap on the Menu button in Firefox and choose Tools | Add-ons. Tap then the Ixquick HTTPS item and tap the Set as Default button. From now on,...
Bye-bye Pocket, Hello Poche!

Aug 08, 2013 GMT

Finally, there is a self-hosted open source alternative to Pocket and Instapaper. Poche is a relatively new project, but it already shows a lot of promise. The application is easy to deploy and it provides all basic functionality which lets you save web pages for later perusal. Written in PHP, Poche will happily run on a machine with the Apache web server, PHP, and the SQLite database engine. To install Poche, grab the latest version of the application from the project's website, unpack the downloaded archive, rename the resulting directory to poche, and move it to the root of your server. Make the poche directory writable by the server using the chown www-data -R poche command, and point...
Track Your Expenses with Budget for Android

Jul 31, 2013 GMT

Keeping track of your expenses is the first step to minimizing them, and Budget with envelopes (or just Budget) can help you with that with a minimum of fuss. This open source app is simplicity itself, which is a positively good thing: an expense app that requires you to go through a convoluted procedure of adding an expense every time you buy a cup of coffee is not of much use after all. Clever design is another highlight of Budget. The app is based around an envelope metaphor, where each envelope represents an expense type (Books, Food, Travel, etc.). You can create as many envelopes as you need, and then add funds to them and subtract...
