I have not tried/used it (yet?), but the kids are building Radicle for this very purpose. It gets a fair amount of techie coverage (blogs, comments, etc.) but sits in unique space compared to, say, Forgejo (classic self-hosted git).

The above said, it wasn’t hard to find a project using XDG and a JSON mapping file (basically your idea fleshed out in python) to get where you want to go if XDG is enough: https://github.com/JonTheNiceGuy/usbrowser

You’re not going to like this answer - there’s a bunch of different ways depending on the app(s) and the desktop environment. The Arch wiki goes over it in detail: https://wiki.archlinux.org/title/Default_applications

I would guess that focusing on the XDG spec and covering Gnome, KDE and Xfce (Xfce can be replaced with anything else like Cinnamon that comes with Mint, “non Gnome or KDE”) is the best plan of attack for what matters to 80%+ of the population.

mote absolutely understands the law, addie is creating and moving goalposts to support their tirade. The person I was responding to made a ludicrous statement, to which I refuted with observable evidence (laws).

It is obvious to any reasonable person I was referring to and talking about the common folding pocket knife, not kitchen knives or other fixed bladed implements. I may not have written “folding” and it was implied, that could have been better. Your choice to move to some other mental place to complain is your choice, not mine.

But let’s get to the meat of your off-kilter tirade - what I have stated and am referring to is an anomaly in the world of knives; the locking mechanisms (there are several designs) on a 3" folding pocket knife is there for user safety. If you have owned and operated pocket knives under force, they can and will twist in your hand. And without a locking mechanism, they can and will snap shut on your fingers and slice you up. I know this personally. It fucking hurts.

I am very aware the UK has banned such an object because they believe it will curtail knife violence. I feel this is trading an actual proven safety feature for “feel good” nanny law that probably don’t matter to someone intent on committing knife violence. It only harms the honest user of the pocket knife who wishes to not mutilate their fingers.

A three-inch blade is allowed provided it doesn’t lock in place; as long as it just folds away (like a swiss army knife) then it’s fine. Three-inch butterfly knife will get you in a lot of bother, though.

You go from from a nice pocket knife to a fucking butterfly knife, like holy shit there’s an entire world of cutlery between those two and you jump to some crazy extreme with butterfly knives. Those knives are actually curtailed by laws of their own (switchblades, butterfly knives and other “assisted open” cutlery is vastly illegal in many places in the world) as they tend to overlap with gang violence laws (“public nuisance” in the legal chapters). This is not the same mechanisms or designs as safety locks on a folding pocket knife used by regular people doing regular things.

The UK outlaws the safety knife (it’s designed for cutting seat belts, smashing a car window and other save your life things) I keep in my vehicle next to a flashlight, because it’s longer than 3" and has a locking mechanism. You are not using this thing for knife violence. (search “spyderco rescue knife”) But, this tool is illegal in the UK because of it’s features.

So yeah, I understand the law. But I also understand knives and cutlery as I’m interested in the steels used, so just happen to learn other things along the way. And to be fair, other countries have just as stupid laws about other things, including my own. I’m specifically discussing this one law and it’s irrelevant it’s the UK for purposes of discussion of the law itself banning a safety feature.

In the UK, a knife with a blade over 3" and/or any safety locking mechanism is illegal. This same extremely common knife is legal to carry (typical utility pocket knife) in a majority of other parts of the world.

So close! you have to do cat < foo.txt :-) (/s)

Al, we need to optimize. Speed and efficiency to prevent Ctrl+C.

Write 16MB of zeros to the beginning of the boot device to overwrite the boot blocks (16MB being extra cautious, 8MB is fine) and if you want to double the roulette fun, have it fork in parallel and do the same thing to the EFI partition (if you have one). Extra credit: fork a 3rd time and write 16MB to the end of the disk, nuking the backup GPT structure sitting there. This can all be a fun inline “one-liner” to appeal to cut & pasters. curl pipe bashers.

It’ll happen so fast there’s no stopping it, their only way out now is to get the running system saved off that disk while it’s mounted.[1] But your nuke is invisible, how long until they find out trying to reboot? Devious Al, you’re just devious.

[1] there is a way to recover if you build identical machines, like VMs or VPSes - a tool such as gdisk can pull the table(s) off one to a file, which can be pushed onto another. We’ve recovered $customer mistakes at $ITjob doing this before, it works. It might not boot properly, but it can contain enough filesystem boundary information to be able to recover a partition manually (rescue).

Briar fits into it’s own niche (operational design), making it a choice for certain activities but not what I would call your general normie chat app. It makes tradeoffs (using the local network, no caching relays, etc.) to increase security posture at the expense of general use. IIRC, Jack Dorsey’s BitChat was modeled after the same designs? (which is interesting, because Nostr his other pet doesn’t)

It’s been in DC for a few versions now, we’ve used a combination of: macOS desktop, Android mobile, Linux desktop, iOS Mobile - and haven’t had problems more than usual getting apps access to the cam/mic on macOS.

They just dropped DC 2.57.0, it hit F-Droid and Arch repos in my morning updates. An update to the relay code was also dropped, 1.12.0, for relay operators.

I haven’t tried SimpleX yet, as they can’t share the same profile to multiple devices (it’s explained in detail in the FAQ) which makes it a normie usability deal killer. I’ve heard it has really bad battery life on mobile too, but that’s just reading random comments. Right now we’re using Delta (and running a relay) and it’s just fine.

My best friend’s band is objectively the best hardcore show you’ve never been to yet. :)

It’s not entirely dystopian (just barely), we have newer messengers like SimpleX and DeltaChat (I/we use Delta) on the up and coming which deliver on all the same e2ee promises as Signal. It’s just network effects as usual, getting people to try is the real hurdle.

What they share in common (mostly) is the architecture - they’re built natively decentralized, utilizing caching relays with no single source of truth, or device of truth, to be used to create a profile of you like a phone number does. Encryption keys owned by the user and no single servers. Generally this is the Nostr design as well, so we have 3 different teams all focusing on the same natively decentralized architecture patterns.

por qué no los dos?

What I like about this one is the nerd friends cheering Sid on, celebrating his success in action. It is, to me, one of the quintessential parts of nerdery - to lift others up and watch them become great.

I would assume your system is using systemd (I don’t use Kubuntu specifically); the laptop lid is (now in 2026) controlled by the systemd infrastructure - it’s a matter of setting a config option and this should fix you up. Arch as usual has the best wiki on the subject:

https://wiki.archlinux.org/title/Power_management#ACPI_events

You’re probably looking at HandleLidSwitch* options. There’s still nothing wrong with the manual disable to /proc/acpi/wakeup to cover your bases (layers of the onion), I’m fighting with a “modern” laptop that only has s2idle and it’s terrible compared to S3 - I’m in ACPI wakeup hell and still trying to figure out what’s causing it.

It’s when you subsist on Lower Class Brats songs during the night hours.

From my understanding (which could be incorrect, I mean I wasn’t there), the pattern applied to the hull was done differently per ship. I imagine they applied the base pattern in a random tile-like build where things can be rotated and moved around in the design before painting.

My first thought when I saw this - “oh hey look, razzle dazzle clothes” which is my personal mental association of the famous scene in Stripes movie, with Dazzle Camouflage which I always thought was a neat idea.

In late May 2026 images appeared on social media showing Russian Ural and KAMAZ trucks painted in the classic dazzle camouflage. Supposedly the unusual paint scheme is to confuse Ukrainian drones controlled by artificial intelligence and disrupt their pattern recognition, and not to trick the human eye. Ukraine has experimented with AI for targeting as seen in Operation Spiderweb, and is conducting a deep strike campaign to disrupt Russian logistics.[72][73]

(just talking shop) I’ve poked at them, you’d think the old.lemmy.ca would be appealing but not for me - I rather like this Lemmy webUI overall as a design. Good font sizes, line spacing and so forth - it has a well formed comfortable feel which I can tell has an experienced eye to it (minor details matter). Conversely, when I look at, say piefed or old.lemmy I just got “ugh, those fonts! that line spacing!”. The default UI is actually a well crafted piece of usability kit - the infobox is an Achilles heel.

Random: I’ve used the Lemmy webUI details to craft similar feeling looks to HackerNews and (old) Reddit using nothing more than uBlock filters. Nothing grandiose but the fine tuning makes them sorta feel like the Lemmy UI (but worse, holy cow is there so much hard coded HTML in these old sites - lipstick on a pig but it helps).
