Une dictature, comme vous y allez !
Right now overlays requires elevated privilèges, but ideally it shouldn't. Rewriting the Linux kernel to implement per user namespaces like plan9 does would allow unprivileged actions from any user (just like if any user was sitting in a container, overlayed from the base system).
I know we're not there, and that's not the direction development is going, but this thread is about dreams, right ? 😉
About the XDG specs, they serve a totally different purpose so they're out of the discussion IMO. I'm not advocating against env variables. Just $PATH which is a workaround as I see it, but your mileage may vary.
As for your "issue" with steam, of course this is the best way to solve it. Because of today's OS limitation. My point is that with a better designed namespacing implementation, there would be more elegant solutions to solve it (and would get rid of the need to use LD_LIBRARY_PATH too, or literally any *_PATH env variable)
By mounting the binary over, I mean something like a bind mount. But in your case of a wrapper script, it doesn't apply indeed. Though in this case I would simply name the script steam-launcher and call it a day 🙂
Having multiple executables with the same name and relying on $PATH and absolute paths feels hackish to me, but that's only a matter of preference at this point.
I'm not saying we should get rid of $PATH right now. My point is that it was created to solve a problem we don't have anymore (not enough disk capacity), but we still keep it out of habit.
As a reminder, the discussion is about what should be rewritten from scratch in linux. And IMO, we should get rid of $PATH as there are better options.
Today's software would probably break, but my point is that $PATH is a relic from ancient times that solved a problem we don't have anymore.
You missed my point. The reason $PATH exists in the first place is because binaries were too large to fit on a single disk, so they were scattered around multiple partitions (/bin, /sbin, /usr/bin, etc...). Now, all your binaries can easily fit on a single partition (weirdly enough, /usr/bin was chosen as the "best candidate" for it), but we still have all the other locations, symlinked there. It just makes no sense.
As for the override mechanism you mention, there are much better tools nowadays to do that (overlayfs for example).
This is what plan9 does for example. There is no need for $PATH because all binaries are in /bin anyways. And to override a binary, you simply "mount" it over the existing one in place.
$PATH shouldn't even be a thing, as today disk space is cheap so there is no need to scatter binaries all over the place.
Historically, /usr was created so that you could mount a new disk here and have more binaries installed on your system when the disk with /bin was full.
And there are just so many other stuff like that which doesn't make sense anymore (/var/tmp comes to mind, /opt, /home which was supposed to be /usr but name was already taken, etc ...).
sysupgrade seems to fetch 7.5 right now. I'll see how well it goes !
Edit: upgrade went fine, running 7.5 now !
Can't wait for next year to keep on investigating this... Girl does have the same "run bad" tatoo as her though so that's why I'm asking ;)
+1 on the Gazzew U4. I just swapped from browns to it and I'm never going back ! They're more tactile and much more silent.
Presoldered split keyboard
Hi everyone! I'm planning on getting a split keyboard to replace my planck, but I don't have a soldering iron.
What are my options ? Ideally I want:
- DIY, no soldering involved
- QMK firmware
- 40% format
The keyboard I'm leaning toward is the let's split as it's a planck split in two halves, but it seems that you need to at least solder the keycaps yourself, which I can't.
Chapter 0x02 - Is it too abstract ?
Hey everyone !
With so many people stuck at 200 points on the board, I'm wondering if the chapter 2 isn't too "abstract" ?
The Cyb3r Hunt is meant to be challenging, but it shouldn't discourage players because they can't figure out what to do.
For those that went past it, did you find the solution sketchy ? Did it all make sense, or you went past it without really understanding what all these files were for ?
For those stuck, where are you stuck at (please use a spoiler tag) ?
I'm considering removing some files I consider "optional", and changing the hint to make it less like a guessing game as to what to do.
Any opinions on this ?

Cyber hunt - A technical adventure for Unix fans!
I've been working on this project for over a year now, and I'm sure many people here will like it !
This is a game where the player must complete technical challenges about various technologies (programming, cryptography, networking, etc...) to progress through the story. It puts the Unix family under the light, and features many opensource technologies all running on a single server!
Check out the about page for details, and happy hunting !
La chasse est ouverte !
Bonjour amis technophiles !
J'avais déjà teasé ce projet il y a 15 jours, et ça y est, le jeu démarre aujourd'hui ! Il reste encore de la place sur le tableau des scores donc c'est le moment de plonger dans cette aventure dystopique et de mettre vos compétences techniques à rude épreuve !
Cyber hunt - An epochalyptic adventure !
Over the past year, I've created technical adventure for people eager to challenge their skill and knowledge about many technical fields, while also having fun !
Programming, version control, command line, network protocols, cryptography, steganography, games, … Thorough the game you'll switch from decades old to state of the art technologies, and use it all to progress through a dystopian story happening around the 2nd Epochalypse.
Get your systems ready, and hope that you'll be done with it before the Advent of Code starts, because you will probably not handle both at the same time ;)
sysupgrade ❤️
Just spreading love for sysupgrade(8).
I had a private server running 7.2 dutyfully serving a PHP software for a local organisation for the past 4 years.
Our provider suffered an outage which brought the server down for a few hours. When it got back up, I decided to use this outage to upgrade it to 7.4.
Two sysupgrade and one pkg_add -u later, the server is up and running again, without further intervention needed.
I did it all from my phone, in a train with a a laggy connection.
Thanks OpenBSD for caring this much about your users ! 🐡♥️
Feeling floppy today ?
CYB3R HUNT is an epochalyptic online adventure of which you are the hero! Check out the about page, the rules, and prepare for the opening on the 31st of october !
Artworks are made by prahou, creator of the unix_surrealism universe (check out his mastodon account for the image on the background, and more quality content!).
As for the programs running :
Début du compte à rebours!
Je viens d'achever la création de ma CYB3R HUNT, une aventure dystopique dont vous êtes le héros!
L'accès ouvrira à la fin du mois, et offrira un grand nombre de challenge techniques allant crescendo en terme de difficulté et d'implication. En progressant dans les défis proposés, vous ferez avancer l'histoire vers son dénouement, et gagnerez des "flags" permettant de mettre à jour votre score sur le tableau général.
Rendez-vous le 31 octobre pour vous mesurer à ce défi technique que je vous propose ! N'hésitez pas à repartager le lien d'ici là; plus on est de fous, plus ont rit ! 😉

Molly closed the lid, and put it next the others, all destroyed by the CYBFARM security module.
There must be a way to bypass it...

Remote storage solution ?
I used to rock a bare metal 1Tib HDD server for 17€/month, that I used as an NFS server for all my other servers which needed storage space.
First of all, NFS kinda sucks and I'm looking for alternative solution that I can use on OpenBSD to mount remote volumes.
Secondly, I'm planning to move this server to hetzner (my current provider), but they lack affordable storage (it's 50€/month for 1Tib). Do you know an hosting provider which would provide high volumes for not so expensive prices ?
Besoin de votre temps CPU
Salut les Français !
Je bosse sur un projet dans le cadre duquel j'ai besoin de construire une table de correspondance entre des mots de passe et leurs hash cryptographiques.
Seulement voilà, l'algorithme de calcul de ces hash (argon2id) est spécifiquement construit pour être long et coûteux a calculer. Or moi j'ai besoin d'un gros volume de données aléatoires (+2Gib), et memes avec toute ma puissance dont je dispose a la maison, ça me prendrait des mois.
J'ai donc mis au point hashcrush, un "brûleur de CPU", qui calcule ces précieux hash en utilisant toute la puissance disponible sur la machine qui l'exécute. Je l'ai testé sous Linux et OpenBSD.
Parce que je crois en l''esprit communautaire et l'entraide dans la vie de tous les jours, je préfères demander de l'aide au sein des communautés auxquelles j'appartiens plutôt que d'engraisser les fournisseur de service (qui me louerait du CPU à foison pour le même résultat avec grand plaisir).
Donc si vous voulez bien me filer un coup de main, clonez le dépôt et mangez du hash ! Toutes les infos sont sur la page du projet.
Si vous avez des questions, n'hésitez pas à les poser ici.
Merci les copains :)
Edit: pour ceux que ça intéresse, on a atteint l'objectif. Ça nous aura prit 3 jours, contre 8 mois si j'avais fais ça tout seul !
RDP Traps ?
I've recently dug into my firewall logs and the most traffic I seem to receive from internet is targeting port 3389.
While I could just blacklist the source IPs and call it a day, I would like to actually listen on this port and "trap" them in a fake RDP connection.
There are tools like endlessh, and I've found that you can do the same for http by sending an endless stream of headers. I would like to do the same for RDP, and before I start digging into the whole spec, I was wondering if there is already something similar for RDP.
Is anyone aware of that ? Is that even a thing ?
