Disabling system beep in Linux

December 13, 2011

0

I noticed that on my Debian Testing installation the system beep is active, even though my computer has a nice and common integrated sound card. To disable the annoying beeps at start-up and shut-down, the common solution is to blacklist the “pcspkr” module, which is responsible for the beeping noise. I noticed that most advices […]

Encrypting data on USB flash drives with LUKS

August 25, 2011

I wanted to explore a different way to encrypt data on portable USB flash drives other than Truecrypt, so I checked what could be done with Linux Unified Key Setup (LUKS). LUKS is an encryption method that is implemented on Linux by “cryptsetup” package, and on Windows by¬†FreeOTFE. It encrypts a partition or a file […]

Mixing Debian testing and unstable packages

August 7, 2011

I installed Debian testing (wheezy) on my workstation about a month ago. Recently I wanted to install some packages, but they were not in the testing repository because they were blocked by the automatic rules that make a package transition from unstable to testing. For example, the arduino package was held down by gcc-avr and […]

Compiling Linux kernel 3.0 with Emdebian ARM toolchain

The Emdebian project works to bring Debian on embedded platforms, with repositories of custom distributions and toolchains to cross-compile software. I wanted to try their ARM toolchains, and coincidentally the Linux kernel 3.0 has been released in these days, so I tried to cross-compile it and emulate it on QEMU. These tests have been done […]

I have a multi-button mouse (the Trust MI-2950R) with left and right wheel tilt, back and forward thumb buttons and a couple zoom buttons. I want to use them efficiently, and in my case, since I rarely use the horizontal scrolling, I wanted to map on the left-right wheel tilt another function that I use […]

I decided to abandon Ubuntu on my home desktop after the upgrade to 11.04 Natty Narwhal. I knew there were some things that I couldn’t like, but I didn’t know it would cripple the very base of the operating system. These are the things that went bad: The upgrade finished with obscure errors. can’t log […]

QEMU raw images real size

May 8, 2011

Today I noticed a nice thing about using “raw” hard disk images with QEMU: the images are sparse files. What does it mean? Sparse files are an useful feature of many file system formats that saves space in case of files that contain chunks of zero data. My host’s file system is formatted with ext4, […]
