"swarm" means large numbers by definition, otherwise you have... well, plain-old coordination. Large numbers of F-35-sized aircraft is flaunting economics in the face a quite a bit (so I'm sure the US military loves the…
The idea of drone swarms doesn't go well together with aerodynamics and basic physical intuition. If you shrink an aircraft down, the aerodynamic cross-section (i.e the drag force) scales with the area (scale^2), but…
On Win10 you need to have enough swap space on an SSD; HDD I/O has totally kneecapped latency, seemingly due to blind usage of NCQ (AHCI driver got replaced from Win7), so it chokes out entirely when combined with the…
Why the hell does RSA ever get used anymore, esp. in smartcards etc? It's been obsolete for like 10 years thanks to ECC, and ECC is way easier to implement (esp. 127-bit and 521-bit).
Wouldn't code instrumentation be trivially bypassable using an eval construct? esp. something like []["constructor"]["constructor"]("while (true) { }")() Or does Nashorn have a mechanism for forcing the code static?
Not necessarily, 1.3MJ (360 Wh; but screw that unit) of diesel isn't much of an explosive under normal circumstances. It really depends on the maximum power output under normal operation, and whether it can occur…
Good.
Windows 10 is borderline unusable due to it (it evicts RAM very aggressively to use as disk cache). Doesn't help that their IO scheduler is completely screwed up too (and they removed the ability to disable NCQ, so disk…
On that subject, I'm curious whether there is any CPU out there that sets the overflow flag incorrectly when computing (-1) - n when n is the most negative number (which negates to itself, so implementing subtraction by…
As far as I understand, what's happening is: * There's an old feature which causes POP SS/MOV SS instructions to delay all interrupts until the next instruction has executed, to safely allow changing both SS and SP…
To be fair, Intel docs are so consistently gibberish that it might as well be classified a separate language (similar to english, but only a quarter the information density). In this case it seems they just didn't…
It might still be possible. The JVM and .NET both have their speed annihilated by their awful choice of memory model.
The secret to linear algebra is homogenous coordinates together the exterior algebra. plus matrices sprinkled in. If you use those for everything all your problems simply disappear.
I'm not talking about the fundamentally misguided memory-distributed computing stuff, I mean "improve flexibility enough that you can bolt some additional units on as offload" (address translation in this case would…
I've heard a few times that the Cell wasn't all that bad in terms of performance, just very difficult to program. Not sure how true that is, but ostensibly the useability is just a tooling issue. Probably not a tooling…
It'll change if someone can manage to take the "central" out of the CPU internals. You don't necessarily need software to see anything other than a monolithic core, but having to plumb everything through one central…
Personally I'd predict the opposite (and current) pattern, creating generic chips which can replace many ASICs / less generic chips. If you can produce a chip which can replace 10 other low/medium-volume designs,…
GaAs logic is probably happening at some point, just not yet. All improvements like that which would be incredibly expensive to develop will be held off on until all cheaper options have been exhausted. It does seem to…
Seems like most people here are bringing up speed of light problems, which are a concern, but it's not what stops you. The problem is that your yield goes down exponentially with die size, and binning them becomes a…
I think we're far from the ceiling on CPU performance so far, but we seem to have hit a (micro)architectural dead end. Currently a lot of time and transistors is spent simply shuffling data around the chip, or between…
If they do, whatever issues they're occupied with finding would call for an exorcism.
This is what happens when you don't have a QA department.
Probably not gonna have as much luck with the transparency at those thicknesses.
It could potentially allow you to stack 3 infront of eachother to render color instead of needing alternating colored subpixels. Not sure if that would actually be useful for anything besides a density increase, but it…
My ass, mostly. I'm extrapolating based on monitor framerates and how accurately we can see the velocity of fast-moving objects, and that I can spot a timing difference of ~5ms reliably. Human eyes are almost comparable…
