Over the past half year, I’ve had the pleasure of Collaborating with Bellingcat as a contributor to their OSINT (Open-Source Intelligence) challenge platform.

For those who aren’t aware, Bellingcat is an independent investigative journalism group based in the Netherlands that publishes investigations using OSINT about war, human rights abuses and the criminal underground (this description is shamelessly stolen from the Wikipedia article as they describe it well).

This all started back in March 2025, when I published this challenge in their Discord community. The premises are simple: find where that scan was taken.
Just a few minutes later, already three people managed to find the location; a few days later even more. This challenge seemed well-received, and I was contacted by the Producer of Bellingcat to create a few more challenges for their Open-Source Challenges Platform.

All the challenges took half a year to collect, design; and over 6000 km of travel was needed within Europe.
Though I’m a bit sad some scans didn’t make the final cut (some of the ones I originally planned turned out worse than I imagined), the challenges turned good overall.

I want to thank Bellingcat for this opportunity to collaborate, and I encourage anyone to check out the Open-Source Challenge platform, and even donate to them. The challenge scans will be made available within Resonite in 6 months time from now.

Quick blog post to advertise the Resonite panel at Eurofurence 29, which should be next week, on Thursday 4th of September.

If you are attending Eurofurence, direct yourself to the room CCH X 5-8 at 13:00 (local time).

The panel will last approximately an hour and half, and developers and community members will be present.

Hope to see you all there!

Also see Eurofurence events website for more information: https://www.eurofurence.org/EF29/schedule/events/3042.en.html.

When you visited this blog, you might have noticed a new interstitial screen.

This is Anubis, and just like the Egyptian god, it will weigh your soul before granting you entry on my humble blog.

This is mainly to stop the slew of bots and other scrappers that hit my blog all the time, those get annoying and waste resources.

In most cases, the check should be quick enough that you won’t even notice the Anubis challenge screen.

MeuhMeuhCraft was a Minecraft server opened in 2013 which continued up until its closure in 2015.

Young me, playing Minecraft, joined this server. The factions survival world was where I made some friends, and where I also learned some stuff about the game, such as making potions.

It’s last year that a thought came to my mind: what if I could find a save of the world, and see some of those memories again, my friend’s base, my underwater one, etc, etc.

Sadly, the website only had one usable capture on the Internet Archive, so not much slack to play with.

With this in mind, I bought the old domain, meuhmeuhcraft.fr, and hosted a page saying:

I’m trying to contact the owner of this server to have a copy of the world (even if it might not exist any more).

If you have information on this server, please email me at [my email address].

Almost a year after setting this message up, a surprise came in my email. On 2025/06/30, I was contacted by a friend of the owners, asking me for more information as for why I wanted the map. The next day, I was talking directly with one of the owners of the server, something I wouldn’t have expected ever.

More than that, on 2025/07/06, I received a full copy of the world- and of the full server files. So I booted up the server, a CraftBukkit 1.7.2, a copy of the game, and there it was, the old server, in all its glory.

Alas, my old base was completely destroyed, probably a raid shortly after I stopped being active.

More than that, those worlds are now available to visit within Resonite!

Here are the parts I already imported:

• The spawn area: https://go.resonite.com/record/U-j4/R-cf70ce23-1688-436e-ba69-cf2a5826c520
• My old base: https://go.resonite.com/record/U-j4/R-4432301f-ec0d-4c4f-9f01-e28afdd7944f
• Waterside base: https://go.resonite.com/record/U-j4/R-3cbc4ea6-0286-42c6-bb1d-6b187ff7c4fe
• Stadium base: https://go.resonite.com/record/U-j4/R-76792208-744f-4291-b5c7-d24da2d608b8
• Boat base: https://go.resonite.com/record/U-j4/R-cdf95817-8d63-4b09-bd2e-5bc5b4919576

All the text on the signs were eaten by the exporter, so sadly those didn’t survive the export to Resonite.

I want to extend my largest thanks to the server owners, mattoo64 and hombeline64, which took the time to find and send me the maps. Even more, their resolute to back the files up for so long.

Without them, this whole thing couldn’t have happened.

I also want to extend thanks to their friend, who noticed my message and was kind enough to put us in contact with each other.

Stay tuned as a read-only version of the server will be hosted in the future.

In the past, I used to have a few PGP keys that were distributed either manually, or through my website.

As of now, all those keys are invalidated as I switched completely to SSH keys a few years ago.

So, if you want to verify commits, or anything signed that I publish, please use the following keys:

ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIHvTe4xw7OAMA9HJtsHAR5BNNrP9X0hXbtASrgKDdnOT
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIDwCQ4IcPyL/0Nz2jNayUrN0B+zsEZ5oa8BepdtAYZLr

Those are respectively the key used by my workstation, and my laptop.

The easiest way to use those, is to add them to your allowed_signers file, for instance:

*@j4.lc namespaces="git" ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIHvTe4xw7OAMA9HJtsHAR5BNNrP9X0hXbtASrgKDdnOT Workstation
*@j4.lc namespaces="git" ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIDwCQ4IcPyL/0Nz2jNayUrN0B+zsEZ5oa8BepdtAYZLr LaptopCode language: CSS (css)

Time for the monthly music blog post.

Sorry for the lack of posts, I’ve been pretty busy with Resonite and in general.

In any case, the recommended albums and artists this month are:

• WALKM4N by A M 4 N 音楽: A random discovery from the discovery tab, a good one nonetheless.
• Echochamber by Hunz: I already mentioned Hunz in a previous music blog post, Echochamber being his latest album. I’ve been listening to that one on loop for the whole month so far.
• Meganeko discography: Meganeko is an artist I only previous had an album from, but listening to their latest tracks, I decided to grab the entire discography. I vividly recommend as it’s great music.
• Machinarium Soundtrack by Tomáš Dvořák: This one was a friend’s recommendation. I really love the music in this one, one day I’ll pick up the game it’s from.

That’s all for this month, stay tuned for next month for the recommendations.

I have pretty exciting news: I have joined forces with Yellow Dog Man Studios to work on Resonite.

See you in the next post.

I recently got myself a Xiegu X6100 HF transceiver. It’s a pocket-size device that packs 10W of power while plugged, and 5W when on battery.

It also includes an SWR meter and a tuner, which is a nice to have when, like me, you only have kinda shitty antennas.

For the device itself, nothing much to say, it just works, and it’s great! I can hear people talk on 14.122MHz somewhat correctly (tho they can’t hear me for now).

Comes in FT8, it’s a digital mode that I wanted to try for some time now, given it works really well with relatively low power. On Fedora, I use the software WSXJT to receive and transmit this mode.

It has a good integration to the Xiegu, which I can just plug into my computer using a USB-C cable.

I’ve already done plenty of contacts using it, it’s pretty amazing how well it works.

If you want to do a contact, I’m usually on the 20m FT8 frequency of 14.074MHz.

If you haven’t left Telegram behind yet, time to do so.

The CEO of the company, Pavel Durov, posted the following today (archive link with full message):

This summer, Telegram users will gain access to the best AI technology on the market. Elon Musk and I have agreed to a 1-year partnership to bring xAI’s chatbot Grok to our billion+ users and integrate it across all Telegram apps

This time, it’s not a hoax, this is really happening.

At this point, Telegram is on a race to the bottom. Use Signal instead, it doesn’t suck like Telegram.

Edit: if you want to come to the comments to:

1. Complain that Signal isn’t your use case
2. Complain about how “bad” Signal is
3. Try to chip in with suggestions of random messengers
4. Look for some kind of debate on messengers

Think really hard about it and skip it, it’ll make everybody’s day (including yours) better.

Almost one year after hinting to a return, Solokeys is still dead, as shown by their repos, issues, and discussions never being answered.

Funnily enough, they are still selling those on their website, but that goes without saying you shouldn’t even touch those given the great lack of care they’ve shown in the project.
