Jan 25, 2013 GMTTiddlyWiki probably needs no introduction. This nifty little personal non-linear notebook has been around for quite a while, and it has a large base of devoted users. Until recently, TiddlyWiki worked fine with practically any browser, including Mozilla Firefox. But under-the-hood tweaks in the latest release of the popular web browser brought some bad news for TiddlyWiki users: starting with Firefox 15, TiddlyWiki could no longer save changes. To rectify this unfortunate situation, Jeremy Ruston (the original developer of TiddlyWiki) released the TiddlyFox add-on. Install the add-on, and you'll be prompted to enable...
Jan 24, 2013 GMTWant to use your Android tablet as a sketchbook and a tool for taking handwritten notes? Then you need Quill. This open source app (source code is available on the project's Google Code page) offers several essential tools for drawing and scribbling notes, including a pencil and a fountain pen. The latter tool is pressure sensitive (i.e., more pressure results in a thicker line), but this feature works only on tablets with an active pen such as HTC Flyer and Lenovo ThinkPad Tablet. You can specify thickness and color for both pen and pencil. In addition to the Undo and Redo commands, Quill features the Erase tool for...
Jan 23, 2013 GMTHere is a simple trick that makes it significantly easier to locate often-used folders on KDE. Right-click on the desired folder and choose Properties. Under the General tab click on the default blue folder icon and pick a color folder icon you like (e.g., folder-brown or folder-green). Press OK twice to apply the selected icon to the folder. That's all there is to it. Now you can easily spot the folder you need by its color.
Jan 18, 2013 GMTrsync is arguably the best command-line tool for performing local and remote backups, and you can set up a perfectly workable backup solution using a one-line shell script like this: #!/bin/bash rsync -avh sourcedir/ tartgetdirThis solution has one major drawback, though. It simply mirrors the contents of the source directory, so if some files and documents in it get corrupted, the script will duly back up the broken data. One way to solve this problem is to use a rotating backup which takes a full backup archive and then backs up all changed files in separate archives. This means that if anything goes wrong, you can restore data from previous backup archives.There are several...
Jan 14, 2013 GMTNot comfortable with hosting images and files using third-party services? If you already have a Linux server, then you can easily turn it into a no-frills file hosting solution using a PHP script from sebsauvage.net. Download the script and change the default password in it. Rename then the script to index.php, create a separate directory for it on your server (e.g., uploads), and upload the script into it. Use then the chown -R www-data uploads command to make the uploads writable by the server, and you are done. Point your browser to http://127.0.0.1/uploads (replace 127.0.0.1 with the actual IP address or domain...
Jan 11, 2013 GMTDebian and Ubuntu-based Linux distributions offer a wide range of tools for administering the system. For example, you can install packages using the apt-get and dpkg tools, while the apt-cache tool can come in handy for finding specific packages. Then there is the wget utility that can be used to fetch files and archives from remote servers. But to get the most out of these and other tools, you have to learn each and every one of them. wajig offers a solution to the problem. This Python-based tool provides a simplified interface to many system administration tools, making it easier to handle daily computing chores. wajig is available in the official Debian and Ubuntu software...
Jan 07, 2013 GMTThe Maniana task manager app is described as "a perfect solution for every procrastinator." In reality, though, it is a perfect tool for anyone looking for a no-frills solution for keeping tabs on your to-dos and tasks. There are, of course, dozens of apps on Google Play Store in this category, but Maniana has two traits that make it stand out from the crowd. Firstly, the app features a somewhat unorthodox approach to scheduling and managing tasks. Maniana does away with the calendar metaphor, offering only two screens: Today and Tomorrow. You can push any task in the Today screen to the next day by tapping the arrow next to the task (that's what makes Maniana ideal for...
