October 13, 2011

I talked about Convergence before: Convergence: fixing SSL security New Convergence notaries emerge The main list of Convergence notaries is on this Wiki page: Notary list : share and find notaries! Notaries I suggest to add every notary on that list and immediately disable it in the Firefox add-on options, then take your time to […]

Codesourcery toolchains have new site at Mentor Graphics

October 8, 2011

10

This completely slipped under my radar: Mentor Graphics acquired CodeSourcery’s toolchain products some time ago. I found out when I got to their site and it redirected me to Mentor. In my tutorials I often make use of the Lite editions of the Codesourcery toolchains, so this is the new site for reference: Sourcery CodeBench […]

New Convergence notaries emerge

When I talked about Convergence (a new SSL paradigm that improves security while browsing HTTPS sites on Firefox) in this blog post, I noted that the system needed a kickstart to become effective. Luckily, new Convergence notaries start to emerge. SSL Labs now runs its own notary servers, here the details and the instructions to […]

Linux kernel official mirror

October 2, 2011

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 […]

Convergence: fixing SSL security

September 4, 2011

Today I discovered how broken is the current situation for SSL, HTTPS and Certification Authorities (CA), thanks to a Reddit post about a “BlackHat USA 2011″ 48-minutes presentation that is very entertaining to follow: SSL And The Future Of Authenticity “too long; didn’t watch” Here’s a quick summary. The speaker tells a story of a […]

Using the CodeSourcery arm-none-eabi toolchain to compile a minimal "Hello World" example for Stellaris lm3s6965 microcontroller. The microcontroller is emulated through QEMU and the output is written to a serial port.

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 […]

Mixing Debian testing and unstable packages

August 7, 2011

3

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

July 24, 2011

16

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 […]

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, […]
