I’ll probably never be as good, I’ll certainly never stop trying. The things we take for granted today are the revolutions of yesterday.

Linux kernel official mirror

October 2, 2011

0

Recently the main Linux website, kernel.org, was compromised by an hacking attack. Since then, Linus Torvalds decided to use GitHub as the master repository for the whole kernel (here the announcement), and kernel.org has been down for a long time. This has broken some of my old tutorials on this blog. In my tutorials, I […]

Encrypting data on USB flash drives with LUKS

August 25, 2011

4

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 […]

Compiling Linux kernel 3.0 with Emdebian ARM toolchain

July 24, 2011

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 […]

Using getmail to backup Gmail on Linux

July 17, 2011

Even though Gmail has been proven quite reliable over the years, there have been isolated episodes of data loss. In any case, I backup my mail locally: better safe than sorry. On my Linux machine I use “getmail” to download my mail through POP and store it in a single “mbox” file. First of all, […]

Changing amixer volume with mouse buttons

July 12, 2011

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 […]

Moving away from Ubuntu

July 10, 2011

15

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 […]

PyPy as a faster alternative for Python

June 7, 2011

0

It came to my attention today that there’s an alternative interpreter for the Python language which is faster and often viable: it’s called PyPy and uses Just-In-Time compilation to execute Python code. Just-In-Time compilation is a technique that is used successfully in many projects: the .NET Framework, Java, QEMU, … and it has also been […]

QEMU raw images real size

May 8, 2011

3

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, […]

I’m seeding Ubuntu 11.04 Natty Narwhal

April 30, 2011

Ubuntu 11.04 Natty Narwhal has been just released. I’m curently seeding the torrents of the installation images, I feel it’s a small yet effective thing to do to reciprocate the benefits I get for using Ubuntu since 2007, when the release was called Feisty Fawn. I went to the Ubuntu alternative download page, downloaded the […]
