I made a quick demo of how the UI "representation" given out by Hawaii emergency management officials

might work.

and POWER6, PowerPC 970MP, 7447A, and 7450 fail. PowerPC 7447B is maybe a fail.

They did experiment with that in fact:

I think big tech companies are perfectly aware of how people react to their actions.

> may not be algorithmically optimal, but better meet the needs of the community

Yeah, that sounds a bit like a blank check for someone to corrupt the generated output under the guise of a nebulous "It's better for our community" while scaremongering about the big bad algorithm.

She is only asked about it in the last question, and mentions a New York City politician wanting open source algorithms:

> Algorithms make decisions all through his borough, the East Bronx, including where children go to school, where police patrols are assigned, and the schedule for garbage pickup.

Which seems a bit bizarre, open source algorithms would be nice, but the tie in to 'the humanities' seems tenuous at best.

Agreed, I will take the wide-screen ratio god intended (16:10) any day of the week over 16:9.

> Once that has been determined, designed, and goes into production, we start on firmware.

So you use coreboot. Right? Because if you don't, where is this firmware development going on?

Although as someone mentioned below, they are rebranded Clevo machines, and really were designed to run Windows first. Station X is just offering a guarantee that they will run Linux properly.

Any idea what ODM Purism <puri.sm> uses for their components? This is exactly the sort of thing I find interesting.

Is there no way to make this an argument at boot time?

Something like, `ksecerr=log+kill`

Then after you get compromised in some way, you will start to look for better vendors.

You would rather have a self driving car in an undefined state, rather than having it shut down? A random glitch could be just as bad as an exploit; if some chunk of memory gets overwritten and your car decides that the brick wall doesn't actually exist any more, I don't think whether it was an an exploit or not really matters. The occupants end up injured either way.

Ideally mining usage could help drive volume for economies of scale, or at least provide a good used market once this particular boom dies down.

The Zaius/Barreleye systems use the LaGrange chips instead; the quick breakdown I made for wikipedia was:

    Sforza —   50 mm × 50 mm,     4 DDR4, 48 PCIe Lanes, 1 XBus 4B
    Monza —    68.5 mm × 68.5 mm, 8 DDR4, 34 PCIe Lanes, 1 XBus 4B
    LaGrange — 68.5 mm × 68.5 mm, 8 DDR4, 42 PCIe Lanes, 2 XBus 4B

Though I have no idea what XBus is.

POWER and PowerPC chips have been bi-endian for a while. Since POWER3 would be my guess.

For anyone curious about that source code, it is here:

Can you provide a link? Is it an ARM system?

Because there is latency and overhead involved when shuffling things to the GPU, and a lot of the focus on POWER these days is on OpenCAPI/NVLink. If there is an ARM chip fast enough to make OpenCAPI support worthwhile, I would be interested to hear about it.

After some more looking around, talking to someone on reddit.com/r/openpower, and looking at the new site information; the thought is that these are 50 mm × 50 mm Sforza sockets and the 4-core CPUs are 12-cores with 8 cores disabled.
