I maintain a Linux build for an IoT product, and it's been a brutal few months trying to keep up with kernel patches. We're trying to go through certification right now, and one of the questions is effectively "are there any known vulnerabilities, and if so justify why they don't matter". Every time I manage to answer the question, a new set of CVEs comes out and we have to update everything before we can answer it again.
I imagine the people who are committed to keeping LTS versions of the kernel patched are having a terrible time right now. I guess at least AI tools make the patching part easier.

You'd hope so because if it turns out there is an asymmetry between "finding the hole" and "filling the hole" in terms of model capability that's a certified Bad Time(TM) for everyone.
Hell even if there isn't, We still have decades of cruft to fix and we already knew before LLM's that in general defending is harder than attacking, they only have to be lucky once, we have to be lucky every time.
I just tried this, and honestly I'm blown away. The GUI <-> code mapping just makes so much sense. So many CAD libraries fall apart because complex operations get stuck and there's no way out. Being able to drop into the code and tweak/edit stuff is such an amazing escape hatch.
Also - the limited exploration I did with it was really good. Responsive GUI, seems to have many of the features I'd expect. Things like fillets just worked. Really good work!
I'll give a go for a more complex workflow at some point! It would be really nice to have a drawing tool (although I know that's a whole other application) - I often use FreeCAD to generate drawings for carpentry projects.
It's not really useless though. Yes, in some dimensions it is terrible compared to GUI parametric CAD. But in other dimensions it is far more powerful and lets you build really complex stuff quickly and easily.
OpenSCAD is useless for almost all of the things that people actually use CAD for. There are a few minor exceptions like fasteners, gears and procedural art. Most CAD is more like a motorbike or a vacuum cleaner. Good luck with that.
Having worked in the industry for a bit, the reason people talk about "MW of batteries" is because they're usually designed to deliver the capacity for a fixed number of hours. Earlier batteries would do 1 hour (so a battery would typically be 1MW/1MWh) and newer sites coming online are usually 2 hours (so 1MW/2MWh). As battery deployment grows the money is increasingly just in energy arbitrage, so there's a lot of pressure for longer duration storage. If you see a headline MW figure it's a safe bet that it's between 1-2x that in MWh.
Honestly, having an experience of something as a kid gives you absolutely no insight into what it's like to be a parent. Not to mention that every child is drastically different and will react very differently to the same situation.
I thought the millenial journey of discovering their parents sucked through therapy was almost a trope at this point. Certainly the previous generations had more kids, and probably spent less time actively parenting them.
Yeah, give me the iPhone's hardware running Android please. I switched to iPhone because my Android phones kept dying due to hardware issues. Android has a far better keyboard and notification system. Give me it any day.
There's a video on YouTube which shows a world champion shotgun shooter try to shoot down drones before they get to him. His success rate - knowing the drones are coming, ready to go with a loaded shotgun and with elite skill - is really bad. It really opens your eyes to just how scary drones on the battlefield are. You need to hit every single one of them to survive. They just need one to get through to kill you.
Bigger drones would be slower and easier to spot, but even then - if you're not ready and waiting it'll be gone before you have time to react. The only consistent solution for anti-drone warfare is automated. Or nets.
A really neat concept. It uses a special hinge design, a magnetic encoder and torque modulation to control the lift of the rotor as it spins. Completely negates the need for a conventional helicopter's swash plate.
The single motor does have the pretty major downside that it spins the moment it's in the air. I suspect a 2 motor drone with a tail motor would be a lot more practical. But I really like how mechanically simple the rotor hinge design is - it pushes all the complexity into the control algorithm.
Perhaps there are specific applications where the payload spinning could be an advantage, imaging/scanning perhaps (which in the video is going to be in the next iteration for the builder).
I don't think it would be all that useful, give the very way it works (modulating motor speed) - your rotation would not be consistent in speed during even a single turn, which makes exposure times different each frame, and possibly too low.
GP is right and the exposure time difference can be dealt with in software because you can model it. The degree to which you can modulate a modern CCD's exposure time dwarfs the speed of rotation.
I dont know anything about these stuff , but isnot this inefficient when two blades overlapping into each other . that why those TANDEM ROTOR HELICOPTER stuff exists
It seems kind of strange that the entire meat industry exists and is tolerated, yet a few horses in Central Park are making people so angry. Surely these horses have far better lives than the cows did that everyone's tucking into over lunch?
They're in proximity to people that run on a progressive threadmill.
When it became socially opportune to so i've seen city folk elsewhere shift their animal rights stance to defend halal slaughter laws deeming it to be progressive because it's tied to a group lower on the proverbial ladder.
Animal welfare laws don't give atheist butchers the option to be cruel. They're required to stun the animal first. Why give halal/kosher butchers the option to be cruel? Especially if you claim "most do" choose to stun.
Be kinder to animals, change "most do" to "all do" by removing the religious exception.
...and then come the progressive types to defend 1000+ year old ritual slaughter customs.
In the US at least, freedom of religion does grant some exceptions. The Amish do not participate in Social Security and Medicare, for instance, but I cannot opt out. I’m not sure how it works other places.
> Presumably any and every religious tradition on slaughter is better than max-capitalism factory farming style?
It's really not. You're mixing two things, "max-capitalism factory farming" alludes to how the animal is treated while it's alive, e.g. caged hens vs free-range hens, while what we're talking about here is animal suffering via religious ritual slaughter.
Kosher and halal slaughter are not animal-friendly. They mandate cutting the animal's throat but preserving its spinal cord so it feels every possible pain in its last moments alive as the blood drains out.
Stunning it before death and/or putting a bolt through its brain would be a lot more humane, but those methods didn't exist when those religions came up their rules, so of course not one iota of progress can be added.
You'll see that authorities in e.g. the UK have been asked to regulate kosher/halal butchers, require them to at least stun the animal before doing their ritual slaughter... and the authorities chose not to, and let them keep their religious exemption to animal cruelty laws. Kosher and halal slaughterers can choose to stun the animal first, which would be humane, but they don't have to.
I don't normally talk about downvotes but whomever downvoted the informative comment from amiga above should not have, it was very interesting, I learned from it, and as such it's in line with hacker news ideal.
There's nothing strange about this. You're just failing to recognize the obvious.
Would you seriously have the heart to, say, kick, injure, and torture a calf or lamb that you know was heading for slaughter and was going to end up on your plate?
Do you also fail to see why people ban torture despite still permitting killing in circumstances like capital punishment or war or self-defense or whatever? Would you be okay with getting tortured during your life if you were sentenced to death?
Just because society blessed your excuse to kill a living being, that doesn't make it strange or illogical to oppose your cruelty or their torture during their life. I'm not even taking a position here; this is so obviously not hard to comprehend. If you're looking to point out hypocrisy, this is not an example of it.
You should re-read the comment you replied to. It was not commenting on the killing of animals, but rather on the horrific ways animals are abused while they live. The killing is the least odious part of the meat industry.
Everyone is talking about the slaughter method in the other threads...
Anyway, even in that case, I can't make sense of this logic. You're expecting people to condone cruelty on their own front porches in the city that their government has full jurisdiction over until they tackle the cruelty of industrial agriculture in other jurisdictions? I guess they can't tackle homelessness in their neighborhood either until they feed and shelter the children in Africa? Otherwise they're hypocrites?
But the activists are not the point. Animal rights activists are a minority, things change because the majority or a significant share of people backs them.
In this case this large group that backs banning horse drawn carriages is very likely eating industrially produced meat. That’s the inconsistency, 95% of Americans eat meat and a substantial share cause far greater inhumanity on animals through their diets which are completely optional (as in, they could vote with their mouth and stop it), than these horse drawn carriages which they want to ban.
I think if a bunch of horses were dropping dead in my city from heat exhaustion, and the only upside to having them was that they congested the roads and left shit everywhere, then I would weigh the two and probably say better to not have them. Turns out 78% of registered New Yorkers agree. Maybe they are all massive hypocrites and should actually support this, since they also eat meat.
I imagine the people who are committed to keeping LTS versions of the kernel patched are having a terrible time right now. I guess at least AI tools make the patching part easier.
