'Beyond stupid': Linus Torvalds trashes 5.8 Linux kernel patch over opt-in Intel CPU bug mitigation

TechnicalBen Silver badge

Re: There must be a simpler fix...

AFAIK AMD is working on full encryption across the CPU. The problem is, that if the software has access at all, it's just a waiting game before you can decode the "key". As I don't think 256bit AES encryption is going ot be blazingly fast on the CPU for every bit execution. But some simple encryption in memory does mitigate it in part.

If you train an AI model on only perfect driving... your AI won't know what to do when it "sees" (it won't, as it's not trained on it, but it will get a feed from the cameras/lidar/sonar) an over turned truck.

"There is an over turned truck in front of you."

AI, blankly "OK, so I continue on into it?"

At least with the rocket science they have a scope/outline of all possible outcomes, even if unlikely, and try to cover all bases of failure modes. With self driving cars, I've yet to see anyone cover the basic failure modes, let alone an exhaustive one!

Re: WD Market Segmentation Blot

IS it worth the cost and time and effort to sort out? If not, just go for CMR.

If it's worth the effort, you can test, test and test again for this new type of drive behaviour (SMR that does not report as SMR and hopes you can trust it to do things right, and not do garbage collection at the worse time).

At least so far with SSDs they learnt their lesson, and most will be made to have decent garbage collection speeds and controllers that can cope with it (though I've had at least one SSD that died after 15 mins ever single time after a firmware level clearance of the entire drive, so good, it never worked!).

Sometimes you *can* do something and make new technology. But you need to ask if it's worth the hassle, and if there is a use case. Here SMR can be used in some types of NAS, and in others... it might chug.

Re: At least..

Is this purely an autopilot error? In general these are not are high risk, as the pilots are suppose to check up on it's behaviour. A bit like if your cruise control goes too fast/slow, but still allows you to override/turn it off at any point. A problem, but not as bad as breaks failing.

Swedish data centre offers rack-scale dielectric immersion cooling

TechnicalBen Silver badge

Re: In days of yore

In tests water cooling is not "better" as such. It has a larger heat sink (the water compared to a copper fin or two), so harder to saturate. Air cooling is still the simplest. And I assume even the noise benefit is still from not saturating it as quickly, thus the fans don't ramp up as quickly. Unless you have more fans on the water cooler sink, in which case, it's more fans and a big copper heatsink would also do the same and similar dB noise.

Is it more flexible in positioning in cases? Does it allow for larger radiators? Yes. Is it "better"? Results may vary. ;)

Not fine combed the article...

Are you sure it's due to reference of race? And not just to remove ambiguity in spec sheets, reference material, and those who prefer "red/green" or "orange/purple" etc etc.

I mean, "allow/deny" is less arguments in the new open plan, coffee free, avocado painted, electric scooter cluttered "office" designing the latest buzz word laden "app" than having to chose the specific colour of eggshell blue for the accept button. :P

TechnicalBen Silver badge


Is the bank using it international?

As for software, it often is, and colour (though sometimes international) is a local and social, traditional option for reference.

So it can cause confusion, or be a buzzword. Where as "allow list" and "deny list" are easier to translate and implement.

Also see time, clocks, calendars and just about anything human being way way more complex once you decide to try and program it! :D

Re: Its all binary

No but you can copyright them. See Sony and their DRM keys.

Re: Its all binary

PS, yes I know pi is not proven to cover (or not to cover) all possible sequences. However, the beer reminded me that pie covers all possible fillings. As least the generic "meat pie" could be any possibility of filling.

That and I'd still leave the excercise to the reader "go on then, prove it does not, find me one sequence that is not in there" and I munch on another pasty (the things I miss in lockdown).

TechnicalBen Silver badge

Re: Its all binary

Nah they are safe. You could take them to court. But all they have to do is ask you to present the number pi or the number e to the courts as proof you *have* the copywrite.

As their numbers are transcendental, and your binary outputs (though infinite) are integer collections/finite listings (approaching infinity), you may have a long time, or require a lot of storage space, to present it to the court.

And thus they can just drag it through the court longer than Miky Mouse can hold onto anything, and literally wait for an eternity for it to be thrown out on a waste of time. ;)

TechnicalBen Silver badge

Re: Its all binary

I owned pi before you even considered your binary list. As pi covers all possible sequences, I win.

At least I remember eating pie, everything after that is all fuzzy.

I hope your not on you're way to Mars. We know the dangers of using a Martian meter (measured from its equator) vs a luna meter (measured for *its* equator) can cause "rapid unplanned disassembly events. Even worse if you use some sort of ancient non universal measuring device, like a body part...

Re: It didn't affect us

There is a tiny road off the main town through road (also small in comparison to most) snuck between the tiny co-ops car park and a bus stop in our town center. The road is one way, and hits 2 other roads in a 3 way junction, then another 20 foot and you get another 3 way T junction onto an off road that heads out of town down a country route (not main route).

Somehow. Impossibly. In the space of 20 foot, someone came off the main road at speed, around the corner *fine* but planted the car into the corner of someones house. Even weirder they went through a metal railing and a brick wall, and have near demolished an entire cornet of this house (rental, so thankfully those living there are now rehomed).

I can see they did it. They crashed at speed. But unless dive bombing from the air after jumping out a helicopter, I have no idea how they managed it. There is just not the space or cornering to get the car in that positions. They deserve a medal for just doing the impossible!

Somewhere, way out there, two black holes, one large and one small, merged. And here on Earth, we detected the gravitational wave blast

Re: Another silly question...

Yeah, I'll have to go back and read some articles. Some large events happen, buy are often considered to be the accretion disk (stars blown out of the center of large galaxies, or large "eruptions" of matter from the surroundings of smaller mergers).

But two black holes larger than our solar system merging? The spacetime distortions to that are mind boggling! :D

TechnicalBen Silver badge

Re: Another silly question...

Iirc some black hole masses suggest galaxy mergers? And with thay one assumes the super massive black holes in the can merge? Or would speeds (due to distances as they always form far apart) cause them to fling past each other?

Either way galaxy mergers within detector range are astronomically less often than a few solar mass mergers. Lol

Re: Satelite designers missed a trick

No. Just no.

Their actual proposals, with the math and fuel budgets calculated, do this exact thing. Multiple sat servicing and refuelling lines.

These things are fuels *on the ground* thus connectors are easy to design, they already have them.

The harder part is welding/sealing after and mating the connectors. They are currently considering an arm to send out the fuel lines/open the connectors. I suppose as this is safer/more multi-functional than a simple docking port, as the port may get in the way of some complex satellite designs.

Re: Makes me wonder...

The engines will eventually run out of propellant.

However, if you are really clever (for example, a rocket scientist... or satellite scientist in this case), you can use the magnetic field of earth, solar radiation, or other forces (atmospheric drag) to make some orientation adjustments. You just cannot really boost the orbit with this method. You need fuel for that, unless using a solar sail (which they have in the works) or a photon drive (which is any light source, but getting one bright/strong enough is the hard part!).
