> A photo frame in your home that rotates through a set of photos.
The e-ink photo frames that do this pretty much all use spectra panels instead of kaleido panels. Kaleido is a grayscale eink panel with a color filter array on top, spectra uses eink cells with up to six different pigments.
Spectra ends up being much brighter/clearer and with much better color fidelity (like nice magazine print vs color newspaper), but the downside is that it can take like 30 seconds to properly refresh the panel. That's unacceptable for a tablet, but fine for a photo frame.
4 transistors for a two-input NAND gate in CMOS.
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.
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).

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.
Earthquakes.
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.
