There’s an anecdote that comes up in software about people working on missile software not caring about memory leaks because it’s going to explode anyway before that becomes an issue.
Who cares about bugs in your software if it’s a hobby project that’s going to blow up anyway.
Also, including Claude doesn’t inherently mean vibe coded, it can be for writing tests, small components, or debugging.

No matter how mad this makes people, its still true.
What makes the code actually useful in most cases however, is enough understanding of the program to modify as its needed. That’s where LLMs fall flat. Even when the code works, its terrible at adjusting the code to fit a specific use case. Dont even get met started on usable documentation or maintenance.
Using an LLM to write tests and small components is still vibe coding.
- 16 hours
Wikipedia says:
Vibe coding involves accepting AI-generated code without reviewing it,
If you are using LLMs to write e.g. small components, then you are typically understanding the structure of the program, and reviewing it.
There’s nothing inherent to small components to suggest that you have to review them. If they’re small, it’s easier to tell yourself that the LLM probably got them right and you’re justified in not checking.

Yes. I am actually surprised we haven’t seen a major terrorist attack in a western country using remote controlled or autonomous drones for example. The technology has been available for years now.
3D printed home made guns like the FGC-9 and Urutau have been around for a while now, but remain marginal in gun crime.
As you say, the cat is out the bag and on the internet forever. However homemade guns and instructions on how to make them have been around for decades.
The lack of simple attacks on soft targets is proof that the threat is overstated and that a statistically overwhelming portion of humans simply don’t want to put bombs on busses and rig them to explode on bridges or in tunnels.

Most western terrorist attacks are by opportunistic losers who don’t have the knowledge or motivation to do something like this.
They’d rather drive a car into people who make them angry and use a gun they already own.
As for organized groups until recently there have been any good reason for an attack from any centrally organized group.

If I’m understanding this correctly, this is more valuable to underfunded military forces but not for the 3d printed ghost gun types. This doesn’t include propellent or explosives, which are the controlled parts. That’s awesome though.

I assure you those do not magically translate to rocket propellent and high grade secondary explosives.
Notably absent… the explosives.
But sure, if you are wondering how folks out in Yemen or Gaza managed to retaliate against their oppressors for so long, this is a textbook example of how and why. What’s being proposed is collection of technology we’ve had since at least the 1960s that’s slowly made its way into civilian circulation.
Also…
Khojayev’s just-launched prototype has no effectiveness track record
I mean, we’re seeing what “just-launched prototypes with no effective track record” have accomplished on the Ukraine-Russia front-lines and it’s a decidedly mixed bag.
I think a harder question to answer is “Who would be interested in putting one of these into practical use?” And that gets to the real value-add of a Stinger MANPAD. Namely, the humans willing and practiced enough to use it.
Also - and again, this cannot be overstated - the model above has no explosives installed. Idk how confident I’d be around one of these things if it was actually armed.
- sudoshakes@reddthat.comEnglish1 day
I synthesize energetics. I can make a primary explosive that is stable enough for cap usage with a solo cup. I can synthesize secondaries like RDX above (one of the more complicated common ones) in short order with a basic chemistry set and the internet to order basic reagents. None are controlled substances.
It is trivially easy to make effective shapes charges and energetics at home.
Synthesis is federally legal in the US so long as you do not assemble into a device or transport. You can do both with an SOT as an FFL.
If I wanted to, I could make a shaped charge that was point imitated and base detonated for the above projectile and it would punch through about 1.5 feet of homogeneously rolled steel.
The limit to threat is not the access to explosives, as the chemistry and processes are published freely online as easy to replicate. The drone parts and control surface actuation is by far harder and I say this as someone who has a professional background in computer science and software engineering.

You’ve got enough information to try to execute the above formula. Okay. And you’ve still got all your fingers after attempting this… more than zero times?

Absolutely. We invented gunpowder centuries before we invented airplanes.
That said… as an anecdote, I had a friend who had a janitorial position. Cleaning a particularly stubborn toilet and dumped a bunch of bleach into the bowl. His coworker came in behind him and proceeded to piss in said boil, creating a toxic miasma that forced them to exit the restroom quickly and heavily ventilate it before returning.
“I could cook up some blasting caps with the trash from a frat party” is a theoretically believable claim.
“Every time I clean up a frat party, I add a dozen shaped charges to my inventory” is not.
- sudoshakes@reddthat.comEnglish1 day
Safely? Yes.
Keep the reaction stirring under ice and if you see the temp rise above 15 C you dump the whole thing in a water bucket or you get a runaway exothermic reaction that is never good with a high explosive forming crystals in the solution.
If you are stupid, don’t ventilate, or are stupid stupid it will light your shed on fire and potentially kill you.
That’s why you work at lab scale, and why you always keep your reactions under the temp limits with acids added slowly.
Basic chemistry safety covers all the bases here.
My preferred blasting caps are nickel guanidine based. I can play with the crystal morphology to produce small more friction inert powder and it is an extremely simple synthesis.
You can use reloading press combined with highly suggested lexan sheet as a blast shield and wooden block to gently press the powder into caps. China sells packs of 1000 electrical ignition assemblies for $40 that you can then set off with a COTS or a clacker.
I cannot emphasize enough that working at small scale and knowing what you are doing are important, but in faster time than it takes to print the parts for that drone you can absolutely complete the reaction, do some recrystalizstion, dry your product,and be ready to mix with plasticizer.

It’s not a MANPAD really.
The sensor package has no IR sensor (or radar unit) and no way to proximity fuse.
It has GPS, accelerometer and barometric pressure. It’s more like a rocket powered artillery shell than an anti-air weapon.
Or, given the lack of payload, it’s more like a high speed burrito delivery device.

Turning a laptop battery into a weapon is a non-trivial endeavor. The absurdity of TSA was more their attempt to police based on weak science than the real danger of an airplane full of lithium battery powered devices.
You don’t need explosives. It has a spot in the front for a camera. One of the new microcontrollers with AI accelerators can do face recognition extremely quickly. It would be possible to use it as an assassination tool.
Even if you changed nothing about the design, the speed and mass of the thing hitting a person in the face could kill.

As the bps space YouTube channel has shown, reliability is paramount in any launch, especially a guided launch.
That and people duck when shit flies at them, unless it’s supersonic, which again, as bps space has shown, control of a supersonic flight is extremely difficult to get right.
This is a guy who landed a hobby rocket like a tesla booster.
But at $100 a pop, you could have backups. (or payloads)
Why kill only one when you can do a whole blast and get a multi-kill?

You know, I’m still struggling to believe the story I’ve been told about that. “The US bombed an elementary school.”
For my entire life, the US has demonstrated precision munitions. The AGM-114 Ginsu is an air-to-ground laser-guided rocket that can kill an individual passenger in a car. We can fly a Tomahawk cruise missile into a specific window of a building. I’ve seen a bridge in Iraq bombed seconds after the last car crossed. Not saying GI Joe is a paragon of virtue, I’ve seen the pictures from Abu Ghraib, but…That shit sounds a lot more like Israel than us.
Even in the “no kill like overkill” “We don’t target coordinates, we target grid squares” “enemy fire is coming from that way, destroy that way” United States, that shit sounds a lot more like Israel than us.
We’re certainly attacking Iran because Israel wanted us to.
One of the stills from one of the videos that the BBC showed identifying it as a Tomahawk showed it at a very un-cruise-missile way up, so it could just have malfunctioned during terminal guidance or been clipped but not destroyed by air defence, and then hit the wrong target. It could also just have been a governmenty-looking building close enough to an intended target that whoever was checking it didn’t notice it wasn’t the target. It’s a lot easier to get everything right when the whole mission is to hit one person with one missile when everyone’s got enough time to do their job perfectly and everything’s been rehearsed than when there are thousands of targets and people are doing things in a rush, especially if orders are coming from people who don’t care about international law.

I have this idea: Scientists some time ago, discovered they could knot light into loops.
Would it be possible to make a curved laser for laser artillery?
Certainly possible. But you’re still stuck on the r2 problem of diminishing returns at a distance. Light doesn’t like staying in a tight beam. The vortex loop is typically not much bigger than the wavelength. I don’t see much of a solution for transmitting energy long distances through air.

Atomize* some propelant, boom, explosive.
* english choose the dumbest word for “zerstäuben”.
Atomize* some propelant, boom, explosive.
The trick is to get the atomized propelant to “boom, explosive” at the target and not in your backpack.
Also, you probably want a “boom” sufficient to accomplish whatever demolition you’re planning, which - again - raises the stakes regarding what’s in your backpack.
There’s a classic little film called “The Wages of Fear” that explores the hazards of amateurs transporting high explosives over long distances.

Tannerite comes to mind. It explodes from a high impact, and little else. I’m not sure what sort of yield you’d get. That stuff mostly just makes a pop and smoke.

- MonkderVierte@lemmy.zipEnglish2 days
I mean, spray the leftover fuel into the oxygen-filled head only on target? It wouldn’t stay atomized for long anyway. And for the boom, the shell needs only be strong enough. Wouldn’t that work?
Sure, there’s more effective explosives.
Wouldn’t that work?
Idk, you wanna find out?
Listen, if you’ve got the specs for military ordinance and want to say “We’ve done this a thousand times, it works fine” that’s one thing.
But it’s very much another to just wave your hands and announce “you know, the boom-boom juice goes here and the detonator goes there and it’ll probably do something.”

Atomize, from the original Ancient Greek adjective atomos, meaning “uncuttable” or “indivisible”.
Seems pretty apt to me. You have rendered it into its smallest constituent pieces through physical means, any further reduction requires chemical processes, or high energy physics. Coincidentally, a simple spark provides both.
