On FreeBSD Jails, coming from Docker

Wed, 22 Apr 2026 10:01:18 +0100

Thoughts and opinions on what I learned, often the hard way, while configuring a FreeBSD server behind a CG-NAT and migrating a small Docker infrastructure to a Jail-based one: Networking woos, trade-offs and web services gotchas.

Nginx resolver and proxy_pass URL behavior

Wed, 04 Mar 2026 17:17:23 +0100

Quick post about a specific issue I met with Nginx when using DNS resolvers and variables instead of hardcoding URL into a proxy_pass directive: URL processing is affected, and I didn’t know that. It probably bitten me several time already, so here it is.

FreeBSD 14 Installation over PXE

Sun, 22 Sep 2024 07:51:56 +0200

I set up a small virtulization server by installing FreeBSD using my desktop computer with Dnsmasq, an old Netgear router, mfsBSD and a ThinkCentre M710q booting over PXE. It was not as hard as I thought but still pretty involved compared to dd-ing an ISO file on a usb stick. This post describes the general process I followed to get the thingie to boot a fresh FreeBSD installation.

A few words about SuperCollider for The Creative Musician...

Sat, 10 Aug 2024 13:52:23 +0200

… And learning SuperCollider in general.

This wordy post contains my honest thoughts about this book and a few considerations about learning resources on SuperCollider and what helped me getting somewhere else than the bottom of a very steep learning curve.

Working with SuperCollider in Emacs

Sat, 10 Aug 2024 12:55:58 +0200

I had much trouble getting the SuperCollider extension to work in Emacs and gave up several times because the default IDE is good enough. I still wanted to edit and evaluate my SC projects like I would for other languages.

I spent, like for everything Emacs related when you don’t know Elisp well, an ungodly amount of time trying to fix that. This post shortly describes what worked for me.

A few words about Deus Ex: Mankind Divided

Mon, 15 Apr 2024 08:30:00 +0200

Game studios performing necromancy on legendary licenses commonly end up with a product deemed, often legitimately, unfaithful and unworthy of wearing its name by a nostalgic fanbase. A recent playthrough of the latest Deux Ex title made me reflect on several things, like what can be considered a successful sequel to a revered GOATY from two decades ago, how the same team managed to bounce from a very mid proposition to a good AAA game, how everything beside graphics seems to evolve slowly, why cyberpunk is shit when it’s not incidental, etc. Thinking emoji.

I initially intended to cover all of that but I settled on simply explaining why it’s worth playing.

Retour de lecture: Ernst Junger, Sur Les Falaises de Marbre

Wed, 03 Jan 2024 00:00:00 +0000

Face à la terreur grandissante ménagée par des bandes d’envahisseurs, deux frères s’abandonnent à la botanique plutôt que de succomber au désir de vengeance et sombrer eux-mêmes dans la barbarie. Fiction champêtre sur l’exercice de la dignité quand tout se dérobe sous nos pieds et que la réalisation du pire est imminente, ou pas.

Retour de lecture: Kafka, Le Chateau

Sun, 24 Sep 2023 00:00:00 +0000

Cette note à l’origine personnelle participe à journaliser l’objectif très clément de finir au moins dix livres au cours de cette année. Quelques spoilers, mais l’intérêt du roman réside ailleurs que dans les composantes élémentaires de sa narration. D’autres notes similaires pourraient être publiées à l’avenir, dans la langue des livres qu’elles référencent.

Fail2ban and Dockers's journald logging driver

Sat, 19 Aug 2023 08:30:00 +0200

The following post describes the procedure followed to configure Docker (rootless) to log the activity of its containers using the journald driver and adapt Fail2ban’s settings to read from it. I mostly had to fish for bits of information in issues or forum posts, so this article may help you achieve the same thing a bit faster.

PSA: Using a Radeon XR 6600 on Debian

Thu, 08 Jun 2023 11:55:57 +0200

I had much trouble understanding why I was facing the dreaded “black screen with blinking cursor during boot” after installing this GPU. This very short note is for the people with the same specific problem. Worth a shot if you still have no clue about what to do.

Docker Reverse Proxying Puzzle

Fri, 25 Jun 2021 21:55:57 +0200

Several issues related to reverse proxying Docker containers were solved only after I learned more about Docker’s bridges and how to debug faulty containers. In this post, I expose the steps I went through to troubleshot and solve this problem, so that maybe it’ll save time to someone, somewhere.

Some Thoughts About Styx : Master Of Shadows

Fri, 25 Jun 2021 14:25:02 +0200

I wanted to share some random thoughts about the game Styx : Master of Shadows on Gog. The review was to be titled Sometimes laborious; still a great title but far exceeded the character limit. This isn’t groundbreaking content, merely a suggestion for Thief enjoyers to try out this game.

Go For Hacking : Endianness Conversion

Mon, 08 Feb 2021 15:32:08 +0100

Endianness conversion, a very common task used in exploit development to represent address spaces, can be done in Go using the bytes and encoding/binary packages. It can replace the struct.pack method from Python 2. Example and explaination below.
