As always, correlation does not imply causation. Someone who is actively playing with the title of their chrome extension may also be playing with any of a dozen other knobs -- all you've observed is that the lights seem to be on over there.

I miss the old Steve Yegge that actually knew how to write coherently. AI psychosis is apparently a hell of a drug... this is pages and pages of complete dreck.

They're so much louder now, though.

I use my own very similar version of this spsc lock-free ring buffer on almost every embedded project I work on that has to stream any sort of sampled data (e.g. audio). You can even have the consumer end be a DMA into something like a uart or USB peripheral so your microcontroller userspace doesn't have to touch the hardware.

Real, genuinely confused human here: Can someone please clarify whether or not gas town is/was a joke? I've searched repeatedly and can't find anything that looks like an obvious tell, and I'm not sure if this is because it's actually real and people are taking it seriously, or because the pages and pages of discourse surrounding it is AI generated and taking itself literally.

If it's not a joke... I have no words. You've all gone insane.

Excuse me, what?

What a misunderstanding -- glass transition temperature means different things for thermoplastics (i.e. anything that comes out of an FDM printer like the CF-ABS in question) and for thermosetting resins like epoxy that actually undergo molecular cross-linking during the curing phase. Thermoplastics will get soft and can deform without limit, while thermosets get rubbery but still more or less hold their formed shape.

Material was CF-ABS

Hey, Joe! This is one of my favorite cello pieces -- so hauntingly beautiful. I've probably listened to Janos Starker's performance dozens of times, but I also liked Inbal Segev's version. Parts of it seemed brighter somehow.

Fuel grade is like 3%. It's exponentially harder to go from 3%-60% (months-years) than 60%-90%(days-weeks). So no, the only reason to enrich that high is to keep your breakout time threateningly short.

I suspected that this was the case when they mentioned adding "one bit at a time" -- the CPU design that they implemented is Olof Kindgren's SERV [0], a tiny bit-serial risc-v CPU/soc (award-winning, of course).

It’s a great achievement, but I’m of course a little sad to see that it’s not mentioned anywhere that Wuji is just a renaming of my CPU, SERV. They even pasted in block diagrams from my documentation.

This doesn't integrate the antenna, so it's not comparable.

I encountered the same issue on my desktop, but ended up doing the partition surgery a little differently.

First I resized /, /home, etc. for some extra space, then I moved them all forward a bit, then I resized /boot. Complicated by various layers of LVM and encryption.

This took longer and in retrospect was perhaps a bit riskier, but it had the advantage of not needing to change any configuration on the actual system (since all of the partition numbers/names/uuids remained the same -- they just showed up at slightly different places with slightly different sizes). So the whole operation could be done entirely from a live/rescue environment.

Rust hasn't fallen off, it's just largely considered mainstream now.

Options are wood again, or steel and concrete.

RIP S3 sleep... Took years to get it to work reliably under Linux, then we had a good decade+ run of it "just working" like this, now back to trying to weed out all the wacky platform quirks and weird hardware/firmware behavior that make the S0ix states be just barely unusable.

Maybe in another five years...

There also seem to be a lot of anecdotal suggestions that learning how to use that AR/HUD single-eyepiece thing when flying the Apache helicopter similarly requires some brain-reorganizing shenanigans to fully master.

Similarly, a lot of these trucks seem to have "farm use only" plates.

Not surprised at all that JIRA is 50 MB, but still... What the fuck

No, this is bad advice. Yes, battery management software has gotten better, but you still can't get around physics. Keeping lithium polymer cells at close to 4.2V per cell for prolonged periods of time will degrade them quickly, regardless of any clever "maintenance mode" hacks that make the cell dance around the top 5% of it's capacity. But also, never charging past 80% will confuse the charge controller and start giving you incorrect percentages if it's not expecting you to do that.

Charge to 80% most days, charge to 100% occasionally, avoid discharging beyond 10 or 15%.

It's the hottest summer on record, who the fuck still wants to go to Palm Springs?

More current produces a stronger magnetic field around the conductor, and superconductors usually have a maximum magnetic field beyond which they stop superconducting.

Carbon fiber composites are a wet noodle in compression. They're supposed to be used under tension.

Hopefully this is the last time anyone tries to make a negative pressure vessel out of carbon fiber.

Here "in practice" actually means "in sheets." If you have a flat sheet of concrete / carbon fiber composite supported at both ends, and then you apply a downward force in the middle, the top of the sheet will be in compression while the bottom of the sheet will be under tension.

In a negative pressure vessel that's a cylindrical shell, all of the force is being applied uniformly inward from the outside surface of the cylinder, so every part of every fiber will be in compression. There's no part of the structure that outside pressure would deform in a direction that would stretch the fibers -- you would need to have greater pressure on the inside for that to happen, and in that case, the fibers would again all be in tension.

One failure mode to consider is shear failure (i.e. if the changes in circumference due to compression on the outside vs. the inside of the hull are too different, resin between layers could start to fail.

The other would be micro-buckling of tiny sections of fiber in areas where the resin has already failed, or isn't as strong, or in layup defects.

If either of these cause enough deviation from the nominal structure shape to allow buckling to start, the hull will fail catastrophically.

Also, think of the bill of a toucan or fiberglass surf board. A lot of rigidity comes from the tensile strength of the skin wrapped around an enclosed volume of relatively weak stuff that mostly keeps the skin in the right configuration.

It is like this, but as another comment [1] pointed out, in the case of a negative pressure vessel, the configuration is unstable -- If you develop just one defect, the entire thing implodes. You might be able to buy yourself a little more headroom with something like pre-stressed / post-tensioned concrete (not sure if there's a practical equivalent for carbon composites), but this is a pretty extreme negative pressure vessel...

JSON is basically perfect

Until you realize you can't actually store real integers because every number in js is a float...

Sure, but is anyone (who has an actual choice) actually choosing to do this? From what I can tell, carriers seem to run a lot of really stupid ads and keep the marketing money faucet flowing for a long time before they finally give up.

What's up with the yellow rectangle?
