Wonder if the same thing applies to sea cucumbers or crinoids.
classichasclass··on Why doctors in America earn so much
The income is most assuredly not okay in residency, or for that matter, fellowship. Most U.S. residencies and fellowships range from $60-$70K a year, basically the U.S. median income, and on a per hour basis is terrible.

It's interesting they describe the xylitol ones as having less burning. Xylitol tends to have a cooling effect on mucous membranes, so maybe that's why.

classichasclass··on The risk of RISC-V: What's going on at SiFive?
So does classic PowerPC, SPARC, and many other ISAs. It's the most common way to handle it on RISC. The Power10 prefixed instruction idea just expands on it.
classichasclass··on The risk of RISC-V: What's going on at SiFive?
> My understanding is that these are rare

Depends on how many bits you had to start with. On Power ISA they aren't common either, but when they happen you need up to seven instructions (lis, ori, rldicl, oris, ori, then for branches mtctr/b(c)ctr) to specify the new address or larger value. Most other RISCs are similar when full 64-bit values must be specified. This is a significant savings.

classichasclass··on The risk of RISC-V: What's going on at SiFive?
Power10 added "prefixed" instructions, which are effectively 64-bit instructions in two 32-bit halves (the nominal instruction size). They are primarily used for larger immediates and branch displacements.

classichasclass··on Microwatt: A tiny Open POWER ISA softcore written in VHDL 2008
That's pretty much what this is.
classichasclass··on The next Raptor OpenPOWER systems are coming, but they won't be Power10
I get that, but if people want choices in architecture, then sometimes economies of scale won't be available for those less-common choices. I'm willing to pay more for a performance-comparable architecture that is more open and less hostile (and, as a bonus, is one I've worked with personally for decades), and I put my money where my mouth is.

Raptor is well aware of their price premium and tried very hard with the Blackbird, though I wanted the expansion power in the Talos II and would have always bought the bigger system first. But they still have to make a profit and I want to support them in it.

I've got one of the Quad G5 Macs too, sitting right next to it (in fact, I upgraded from the Quad directly to the Talos 2).

The Quad is also very quiet in idle, but you have to downclock it in System Preferences to be as silent as the T2 is in normal operation, and even with a well-maintained liquid cooling system the G5's roar at full tilt is loud (it's really loud if it's not). The high speed fans in the T2 are more like a quiet whine than what the G5 generates, let alone the wind tunnel MDD G4 I ran before that. And no LCS!

And the G5 is doing that with four cores and four threads, while the Talos II is doing that with sixteen cores and 64 threads. Now, the Quad G5 also came out in 2005, and I got the T2 in 2018. But thirteen years later I'm happy to say that the noise level is absolutely no worse than any other modern workstation on x86_64.

He meets a rat in that scene (with a nice callback to it in the epilogue), but he shorts out the welding pig to attract service personnel to get him out.

Diamonds is a flawed movie and one of the weirdest Bonds, but it's my favourite because it's so weird.

classichasclass··on Microwatt: A tiny Open POWER ISA softcore written in VHDL 2008
Yeah, in practical implementations the 32-bit Power condition register is more like eight four-bit ones, and lots of code will run compares in parallel to different fields. It's one of the architecture's notable strengths.
classichasclass··on The next Raptor OpenPOWER systems are coming, but they won't be Power10
x86 and ARM are well maintained because they're 30-40 years old, but Power (it's not an acronym anymore) is not because it's 35 years old?

I also suspect you're making the typical mistake of confusing PowerPC with modern Power ISA. They overlap strongly and PowerPC was virtually designed to be 64-bit ready from the very beginning, but chips based on the modern ISA are much more sophisticated.

As someone who actually works on ppc64, the biggest two things that bother me about the ISA are the weirdness with r0 and the large number of instructions that must be implemented to be practical on a new design. Those are comparable to the quirks of any other "successful" ISA by your standards. They hardly make it junk.

Price is one thing, but the Talos 2 I'm typing this on is whisper-quiet. I only hear it when the fans spool up during a heavy compute job. Otherwise it's silent except for whatever case fans you choose to have.

(author) Raptor is probably just hosting them on their own cloud platform. My conversations with Raptor indicate it's a different company. I've got an inquiry out to chat with them and it's been passed along.

classichasclass··on Long gone, DEC is still powering the world of computing
For that matter, PA Semi was itself a Power licensee. They were developing the PA6T, which might have been in whatever the next PowerBook would have been. After the purchase, Apple still had to make promises about its availability because it was being used in some military applications even though they would never use the PA6T in one of their own machines. I think the AmigaOne X1000 was the only generally available computer that ever used it.
classichasclass··on Valley Fever Is a Growing Fungal Threat to Outdoor Workers
It's definitely not top of mind for most physicians, no. Even in my hyperspecialized world I need to have a certain level of suspicion, and I've made the diagnosis not infrequently. VF is way underdiagnosed.
classichasclass··on Valley Fever Is a Growing Fungal Threat to Outdoor Workers
It's a disease that we run into in TB control programs in certain areas because it can resemble it on chest X-ray. Most people with it I've encountered did okay with modest or even no treatment, but I had one case who ended up with it chronically and all I could do was suppress it. Trying to control dust and reduce inhalation are right now the best options to prevent it, and everyone acknowledges it's nowhere near enough.
classichasclass··on Valley Fever Is a Growing Fungal Threat to Outdoor Workers
Yes, it can theoretically infect any animal that inhales the arthroconidia (basically its spores), but there has been no documented spread from animals to humans or humans to humans.

And here I thought this was going to be about "Machine Metal Music," which is perversely listenable if you are a fan of tape hiss (no Dolby required). A nice, gauzy snapshot of a tumultuous time.

My Hue lights have never been connected to the Internet, so they'll never have to worry about this. I use my own Perl client: https://www.floodgap.com/software/huepl/

I might not buy another base station again, though, if this gets enforced at that level.

classichasclass··on Greatest “Classic” Mac Laptop: Powerbook G3 Pismo (2021)
The Wally does have one advantage over the Pismo: it runs Rhapsody the best of any laptop (which is to say merely acceptably). If you're into system archaeology and don't want to allocate an entire desktop to that purpose, the Wally is a good fit. Rhapsody is neat, sort of OS X but where Platinum never died.
classichasclass··on The spawn of AtariLab and the Universal Laboratory Interface
I'd figured they were substandard parts to begin with, but it's notable they were already going wrong by then. Still, it seemed that they did a good job when they were new(er), at least. There were many positive reports from schools.
classichasclass··on The spawn of AtariLab and the Universal Laboratory Interface
(author) Thanks! Yes, Atari had a lot of irons in the fire back then. I have to give Warner credit for trying.
