Why I recommend Debian over Ubuntu by now 2017-02-28 No Comments

I recently noticed that I would clearly suggest Debian over Ubuntu to someone about to make that choice. A few reasons why: The Chromium browser lacked so much behind Debian in Ubuntu recently, that payment on AirBnB would fail on Ubuntu (16.10) while working well on Debian; the update/fix took way too long. The corefonts […]

Creating Fedora chroots on Debian, Gentoo, … easily 2017-02-18 No Comments

Hi! Just a quick tip on how to easily create a Fedora chroot environment from (even a non-Fedora) Linux distribution. I am going to show the process on Debian stretch but it’s not be much different elsewhere. Since I am going to leverage pip/PyPI, I need it available — that and a few non-Python widespread […]

Fwd: Security (or lack of) at Number26 2017-01-09 No Comments

Hi! I would like to share a talk that I attended at 33c3. It’s about a company with a banking license and accounts with actual money. Some people downplay these issues as “yeah, but the issues were fixed” and “every major bank probably has something like this”. I would like to reply: With a bit […]

arc4random_uniform and avoiding modulo bias when using a random number generator 2016-07-30 No Comments

Using the arc4random_uniform function is recommend over using arc4random: Former is advertised as not having “modulo bias” issues, see man arc4random. (So I got curious, searched the web a bit, found this blog post, this answer and this link to the source code of one version used by Apple’s. It took me a bit to […]

Disable Komodo IDE debugger (bound to 0.0.0.0, run by default) 2016-03-14 No Comments

Komodo IDE starts a debugger bound to 0.0.0.0, by default. Maker ActiveState’s reaction was rather unprofessional at the time when I asked for an option to bind to 127.0.0.1, instead. I can no longer add links to that post, but I can link to my demo Komodo IDE exploit script up here. Now it seems […]

XScreenSaver unlock dialog tuning 2015-12-19 No Comments

I’m having a bit of trouble accepting that one of the dialogs that is presented to me as frequently as the XScreenSaver unlock window below is by far the least shiny part of my daily Linux desktop experience. Tuning just the knobs that XScreenSaver already comes with, I eventually got to this point: The logo […]

Hi! Among the top rock albums I have run into so far are Imago and Final Conversation of Kings by a band called “The Butterfly effect“. I consider them a bit lesser known, but I don’t have data to back it up. One of my long time favourites. If you can use a hint, check […]
