The "syscall exception" is there to make clear that userspace acting on the defined ABI/API boundary between userspace and the kernel doesn't need to be GPL, even if it is using linux specific userspace APIs that might o

Why is this entire article using an 8 point font? The good news is that whatever asshole made that UI decision is presumably 22 years older now and probably dealing with presbyopia.

If you're dealing with usecases that need to be cooled anyway, you may well be better off with the tradeoff of needing liquid nitrogen cooling and better insulation in exchange for entirely eliminating resistive heat.

Yeah, this guy lost me right there. Speaking as someone who works at Google, but not on anything at all related to ads, browsers, or ad spam detection, I only wish that the attackers who (try to) make a living out of scamming Google and its

The legitimate "raffle" structure in question does not typically require people to pay if they don't win the raffle.

The relevant number here is 15W. In principle USB C goes up to 240W now, but that isn't relevant here. USB-C power is negotiated, with a full blown two way negotiation if you want more than 5 volts (or to draw more than 3 amps). Framew

As an order of magnitude point, my experience has been that a bunch of CPUs trying to xadd has a throughput bottleneck on the scale of once per 50 to 100 nanoseconds. But even if you allow an entire extra order of magnitude, at one per micr

And 17 tons of CO2 is a rounding error above none of society's total emissions -- the US alone is around 5 billion tons per year.

The flip side of this is that people who legitimately have ADHD are surely more likely to have it diagnosed if they're having to deal with the added academic difficulty of going through school almost a year earlier than their September

In that case they almost certainly do have data support. Keep in mind that power dissipation scales with the square of the current. That means that, as a first order approximation, relative to household 15 amp wiring, a 3 amp cable can be 1

The vast majority of C to C "charge" cables are USB 2 cables. I don't believe I have ever received or even seen a "charge only" non-captive C to C cable. A to C cables are a lot more common. Do you have reason to be

Are these "power only" C to C cables something you're explicitly going out and buying or something that comes with these random accessories?

There is no such thing as a C to C cable that is "power only" or doesn't support PD, unless it is grossly spec incompliant. The minimal spec C to C cable is USB 2 data and supports power delivery with currents up to 3 amps (i

A minimum cable -- USB 2.0 and 3 amps only -- can be considerably thinner. You don't need the extra USB 3 wires and the power wires don't need to be nearly as thick. It isn't just a question of cost -- if you want a long cabl

You don't need a counter cyclical business, what you need is somewhat counter cyclical funding. You develop during recession when it is easy to hire people, and when the economy is on the up side of the business cycle you have a produc

If you have items running in the threadpool that are submitting more work to the threadpool, and you care about "high-performance", you probably want those items to run on the same thread for better cache (and memory locality) beh

And while there is a concept of a "famous trademark" that can provide general protection across all industries against trademark dilution, it is extremely unlikely something as generic as a letter and a number would receive such p
