Hi peeps, I’ve been stumbling on this so many times, so I decided to dedicate this post to the following issue: If you connect an USB device to your computer, trying to access it under Linux, you might run into permission issues caused by the UDEV daemon. In my case, I was trying to connect... » read more
Good morning folks out there, I’ve got another neat little feature of emacs for you today, it’s called quoted insert. I stumbled on this, because I use spaces for code indentation in my emacs, but I needed to insert an actual TAB character. So, in this situation, the combination C-q <TAB> is the way to... » read more
Hey people out there, daddy’s got a brand new toy to play with. I’ve bought myself a macBook pro and this piece of pleasure impresses me again day after day. I’ve just discovered that one can sync the addressbook app with their google account. Here you go: Edit the file ~/Library/Preferences/com.apple.iPod.plist 1 { Devices =... » read more
Hey folks, I’ve just discovered another neat feature of gdb: command. I was in a situation where I needed to watch a certain variable on each breakpoint hit. Generally, this is pretty easy in gdb using its watch-feature. Unfortunately, the variable under consideration was a QString. Now, we already have some experience with those little... » read more
I was looking for a tool to set the itunescompilation (see here) ID3-field of certain mp3-files. This is necessary for iTunes to recognize that imported files belong to a compilation (or not). Most of the (decent) Linux tools for id3 tagging are not able to perform that task (including EasyTag). Fortunately, I found eyeD3 (see... » read more
Hey folks out there, as we all know, Emacs has a very powerful (graphical) interface to our beloved debugger GDB. Until five minutes ago, I used to start a program in debug mode by first starting emacs and then invoking M-x gdb, which can take a long time to navigate to the desired binary. Furthermore,... » read more
These days I needed to convert some FLAC (Free Lossless Audio Codec) audio files to mp3. As usual when dealing with audio/video formats, there are lots of (useless) tools available on the internet, most of them being shareware or even voruses (windows). Fortunately, this is a strength of Linux … at least if you are... » read more
If you will ever have to go through the hell of debugging Qt-applications, you might face the problem of printing the contents of QString objects. If you call print on a QString object in gdb, the output will most probably look like the following: {static null = {<No data fields>}, static shared_null = {ref =... » read more

In fact, most developers around the world probably dislike writing comments within their programs, no matter which language is considered. However, exhaustive code documentation improves the overall code quality, and thus also the software quality. Moreover, code documentation is essential in projects where teams with several people work on the same code base. Thus, the... » read more
