This paper (from the same research as his book on high end culinary organizations) is worth a read https://journals.sagepub.com/doi/10.1177/0001839214557638 - he talks about "negotiated joining" which is a similar scheme for placements that works well with undefined job roles.

Its not timing the market if it is exactly offset by the position in the etf

Yeah, I guess this entire thread has been an inadvertent exercise in Cunningham's Law, and maybe Dunning Kruger as well.

I thought I understood this stuff more than I actually do. Guess I have some stuff to learn over the weekend!

So Amazon should be prosecuted too.

No no, it's third party sellers. There's absolutely nothing that can be done about that!

The whole post is written by AI anyway, so its not worth engaging with.

This is exactly what Apple has done, but it does mean soldered memory, as socketed memory at these speeds still hasn't happened. In the server market that is pretty unpopular (even the hyperscalars are apparently reusing DDR4 with CXL in newer machines). DDR6 apparently has twice the memory bandwidth of DDR5 so that will bring it back in line, to around 1TB/s for 12 channels, so comparable but still with standard memory sticks.

That 1tb / 12 channels is a continuous streaming read / write rates? I assume big wide DDR memory, for random "IO", is much slower than compared to HBM.

I feel like at a certain point there are just going to be big SOC packages with 128gb of ram and stacks of cores (each with their own "local" cache) and the 128gb "local" HBM on-package ram will just be the 4th or 5th level cache, and big server boards will have 4 of those and CXL elsewhere for "main" memory.

And things like the VAST stuff also blur lines between high speed local storage and less performant san or bulk commodity storage.

The old memory / storage hierarchies are getting mixed up (again).

Interesting times.

Vera doesn't use soldered memory, it uses SOCAMM2.

Mac ultras would be great if they offered pcie slots to put nvme drives on and ideally an infiniband network card.

They've got thunderbolt 5 which is pretty good and every port has a dedicated controller. You can even network macs together just over thunderbolt.

Not as fast as raw PCIe slots inside the chassis, but I don't think the ghost of steve jobs cares much. He'd tell you that if you've got no taste at all you can put his beautiful machine into ugly junk like from sonnettech and you can go do ugly things elsewhere.

I think apple's happy taking the market they've got and they'll leave the big guns HPC market to nvidia. The margins look great for nvidia right now, but I suspect nvidia's path will be similar to dram's boom/bust cycle more than apple's continuous "premium tool" brand's market positioning.

High Bandwidth Memory uses thousands of interconnects for the data bus. DDR style memory typically uses in the neighborhood of 64 bit transfers at a time.

HBM tends to be integrated onto the package (board, multi chip module, die) because there are really tight signaling and wire routing constraints that make "modularity" impossible.

I remember back in the day you could get motherboards for your 286, 386, and sometimes even 486 with external L1 / L2 / L3 cache -- you'd buy a bunch of static ram dips that you'd populate sockets next to the CPU, and set a bios or DIP switch to enable it. These days that's just not practical because there are too many wires interconnecting the cache to the dies and cache coherence logic, and the speed of light is just too slow and electricity is too messy to put "external" to the die/chip/package, even if the packaging issues could be addressed.

HBM memory is similar -- it's not practical to make a generic interconnect that'd actually work reliably enough to provide field replaceable memory modules as you can with DDR style dimms.

EDIT:

Apparently I'm totally wrong in that these "SOCAMM2" modules have thousands of pads (like a CPU socket) and can in fact run with the same data bus width (1024 bits wide!) as "local" HBM. Very cool. And please ignore my out of date blatherings above. It's still not quite as fast as if you put the HBM in the package, but it's way faster than the DDR style setup.

Apple doesnt use HMB, but its marketing successfully convinced people it does ant thats why ram has to be soldered.

There is no “true answer given all available infomation” maybe unless you give an eval function.

Came here to say this. The tools I use are best for me currently, but I would never argue that they're the best for everyone. Likewise the best tools for most people are probably not the best ones for me. Context is everything.

If search or AI or whatever can suggest a few decent tools I haven't tried that are somewhat within range, I can try them and decide for myself.

But you couldnt apply security updates because Ubuntu was doen

Mini PCs (NUC-ish form factor) are selling a lot now too, small, quiet, most people don't need expansion over what you can get from eg USB4.

Yeah, the DGX Spark could qualify as a mini PC too. The AMD chip is sold as a laptop chip I believe, but I've mostly seen it in mini PCs. And the Framework Desktop. A brand that probably carries a lot of trust among the kind of tinkerers who would consider buying a barebone motherboard in the first place.

5G barely exists and mostly is the same price as 10Gb. 2.6Gb is taking off and mostly replacing 1Gb, but try to find a 5Gb switch, there really arent any, and most appear to be 10Gb switches with 5Gb PHY in them.

Yes thats one thing Musl libc removes.

If the attacker can control newroot/etc/passwd they _still_ get getpwnam to return whatever userid they want. The solution is to not lookup --userspec=username:group inside the chrooted-space, but from outside.

Also, hi how's things? :)

hi! good, how are you doing?

great. still enjoying the algarve working on my secret projects in the sun.

you able to find a reason to come visit? or am i going to have to come to blighty so we can hang out?
