I think it's more to have a big window with lots of RGB LEDs to show off on the internet.
Newer SFF cases from Ncase/Formd/Louqe are designed with perforations or mesh on every exterior surface to maximize air flow. They can support an air-cooled 5090 and an AIO or massive tower cooler for the CPU. Put a 1000W SFX PSU in there and I don't know if you'd really be wanting for anything spec-wise.
Solid copper projectiles are the primary leadless solution on the market but they're much more expensive than the traditional copper jacket over lead core construction.
There's also solutions like Federal Syntech (https://www.federalpremium.com/handgun/syntech/) that doesn't get rid of the lead but fully encapsulates it to avoid the airborne lead problem.
It’s pretty interesting how the deformity and thermal properties of the metal would affect ballistics. I guess silicon is too brittle even though it’s cheap and plentiful and aluminum is probably too light.
That poly is also interesting. the R&D they would’ve had to do to discover a polymer that would contain an exploding bullet as much as possible
Thermal and deformation properties of the metal have no impact on ballistics at all?
Density sure does though.
Which is why 99% of the stuff you’re mentioning doesn’t really work.
Copper is quite dense, but still not as dense as lead, which is why it kinda works. Steel is terrible (but not completely useless). Tungsten works awesome (as does silver and gold), but is cost prohibitive except for specialized applications.
Exterior ballistics: what happens when the projectile is in the air
Terminal ballistics: what happens when the projectile pokes a hole in the paper.
We use jacketed ammo (lead bullet coated in copper) because, with gas-operated guns, that lead dust that gets ground off of the bullet can foul up the mechanisms. Some ranges only let you use jacketed ammo because of the lead dust.
I've had copper pellets get stuck in airguns because they didn't swage to the barrel properly.
Edit: and suppressors for air guns are often called "lead dust collectors" because the drag-stabilizing skirt on a pellet is definitely going to leave some of itself behind. A bullet in a firearm makes a lot more contact with the barrel, so there's a lot more lead to lose.
Yes! They all behave differently inside the gun, so they all affect the ballistics. Specifically, the deformation properties affect the interior ballistics.
haha, no - not to any meaningful degree. Are you getting this from ChatGPT or something?
Jacketing is convenient for encapsulating lead, but you can run gas checked hard cast at generally the same velocities without any real issues. In that case the gas check is due to coppers higher melting/vaporization point. They are more expensive to make however, and finicky, which is why you don’t see it in production bullets.
The ‘copper’ pellet you mention was almost certainly not actually fully copper, but rather copper washed lead. But you can have lead harder than normal copper (heat treated hard cast is extremely hard and ductile), and copper softer than normal lead (annealed copper is extremely soft). Most copper people are used to working with is work hardened, but it’s trivial to make it ‘dead soft’.
That also has nothing to do with aluminum or other rounds you mentioned.
If anyone even uses them, which they don’t outside of very niche cases or experiments where it shows exactly what I am referring to.
density, however, is 99% of it. including for terminal, interior, and every other kind of ballistics. BC is king. And that is something that is impossible to fake, heat treat, work harden, etc. out of.
For example, initial engraving pressure can be changed or negated by minor changes in throat, regardless of anything else. Or a coating. Or any number of other things.
Woah hey, take that back. But I concede both that I kinda went off on what I am interested in, and you might know more about this than I do. And that I was half replying to you, and half explaining why lead is used (neither very well).
I don't actually remember what was at the center of the copper pellets, but I remember concluding that whatever it was, it was harder and lighter than lead and the copper wasn't enough to make it grab the rifling properly. I've also tried zinc tipped pellets with a plastic base. The main concern with air rifles internally is grabbing the rifling, which is what lead excels at. A secondary concern is the resulting lead dust eventually fouling up any mechanisms is uses for repeating. A third, I guess, would be the pellet deforming, which is a case against lead.
I assumed (incorrectly) that the same would apply to most firearms
Ah, Airguns. That makes sense. If you have any more of those pellets, it might be worth taking a pair of cutters to one and seeing what is inside. Maybe copper washed zinc, which would be funny?
Airguns have such a wide range of wildly different criteria, it’s hard to generalize. Ballistic performance (by any definition or subdivision) is pretty much never a primary concern however though?
At least compared to regulations/compliance, cost, entertainment value, safety (aka anti ballistic effectiveness haha), etc.
Airsoft being a prime example. But even the ‘diving cyclinder powered’ Airguns, which can be quite effective by some measures, are still ~ an order of magnitude less pressure than a 45ACP, which is about as low pressure as a firearm cartridge can get? (And one of the first smokeless cartridges still in wide use - well over 100 years old now)
Most airguns are going to struggle to be usefully accurate or powerful at 100 yards (or even make it at all that far), and that’s kind of the minimum range for any rifle. Most rifles with practice can reliably hit targets at 800 yards, and can be lethal out to 2000-3000 yards.
Most handgun users will struggle past 15 yards, but it is rarely the gun. With practice and a competent shooter, almost any handgun can reliably hit ‘gongs’ at 100 yards, and are quite lethal out to at least 800 yards.
In addition to Federal Syntech there is Speer Lawman, which is a bullet type called TMJ or Total Metal Jacket. Lawman has lead free primers. There is a green box variant called RHT that does not use lead in the bullets.
LLM currently produce pretty mediocre code. A lot of that is a "garbage in, garbage out" issue but it's just the current state of things.
If the alternative is noob code or just not doing a task at all, then mediocre is great.
But 90% of the time I'm working in a familiar language/domain so I can grind out better code relatively quickly and do so in a way that's cohesive with nearby code in the codebase. The main use-case I have for AI in that case is writing the trivial unit tests for me.
So it's another "No Silver Bullet" technology where the problem it's fixing isn't the essential problem software engineers are facing.
There's an animated background element with shooting stars that seems to be updating per-pixel. The more pixels it draws, like for a high res screen, the slower the page seems to render. I deleted that element and it scrolled smoothly.
tl;dr seems to be: "Steam makes my work as a modder much harder so I'm done spending my time making broken games on their platform work well" plus a lot of salt.
Bummer for the community but it seems like a reasonable position.
I think part of the issue is that Zuckerberg is a smaller dude and they're pretty big sunglasses so he has a bit of that "Look! I'm wearing dad's glasses!" thing going on.
Big glasses are actually quite popular with women.
Heavy frames and large lenses tend to compensate for larger noses, and other facial issues (although they won't come out and say that). Clear glasses can really focus on the eyes.
I know a couple of women that have made large, heavy-rimmed glasses into a real fashion statement.
At one point Tesla had the opportunity to become THE ev charging monopoly.
That ended when Musk went on one of his earlier whimsical firing sprees and destroyed the charging team. Had he instead beefed it up, charging could become a money printing machine. Even with his sabotage of the charging teams, Tesla charging is better than other but it could have been so much more
> At one point Tesla had the opportunity to become THE ev charging monopoly.
Why would you want to be that, though? The only way to maintain that would be to run it at very low margins; it's hard to imagine a more commodity product and if you have high margins and significant revenue, people will just set up competitors with slightly lower margins.
This is the answer!
It is definitely coming down and will reflect business fundamentals at some point.
But please don't try to predict when, or you will lose lots of money.
"Market can stay irrational longer than you can remain solvent"
And they will stay even more irrational if the CEO attacking shortsellers becomes the co-president of the United States. It's no surprise that the short-seller Hindenberg Research shut its doors just as the Trump administration was assuming power, as the rest of the country watched on incredulously as Pam Bondi breathlessly bragged about going after a bunch of vandals of Tesla car dealerships as her most impressive accomplishment as DoJ of the USA in the first (?) cabinet meeting with Trump.
Yeah, the whole "they give nothing back" line might be the worst part of the PR around these changes. It's obvious to anyone familiar with the ecosystem that it's not true, which damages the credibility of Redis's argument in the eyes of the people who matter most.
> Why does chrome demand $400m in input spend ongoing, if it no longer has to deliver Google specific changes?
I don't know if it needs $400m but I wouldn't be surprised if it's $20m+ just to keep the browser secure.
Google paid out $12m last year in bug bounties and I assume they spend that much or more for in-house security researchers/developers (headcount is expensive) and periodic independent audits of the codebase.
