They used the Intel compiler. We know for a fact Intel’s compilers deliberately don’t optimize as well for non-Intel chips. That’s damning in and of itself.

In practice a lot of Cat5e cabling can support 10Gbe up to ~40m. I guess the standards folks are hoping future equipment just supports 2.5Gb, 5Gb, and 10Gb then auto-detects the link quality and scales to whatever the cabling can support.

Do you have an FB number for improving the documentation here? CALayer accepts a number of different data types for its contents property, IOSurface being one of them. Another tip: CAShapeLayer draws on the GPU so simple shapes/strokes

Supporting the alternate modes, Thunderbolt 3, power delivery, etc with a hub isn't trivial. Thunderbolt requires a PCI bridge for starters. It is highly likely any such hub would be a USB-3.x hub only but wouldn't support power p

There's a rule: If Stallman is invited to speak at your conference under NO circumstances should you allow him to stay at your place, nor at the home of anyone you care about or even don't outright hate (ask Miguel de Icaza about

There's a balance. People might _say_ they want more content but sometimes when you give it to them they get bored.

The alternative in most cases is _no documentation at all_. It's not like people would go spend two hours writing up documentation if Slack didn't exist.

I integrated a really simple JS runtime into a C# project once and found the same thing. V8 was orders of magnitude slower due to the interop overhead. Even though the IronJS compiler was very simplistic it was just so much faster to do it

You seem to be engaging in a "No True Scotsman" argument here. I could point to MRIs and SQUID, but I guess you could claim some animals sense magnetism (for wayfinding or determining north). I don't consider those to be in t

Use of the vast majority of the radio spectrum is not used by any form of life that we know of. Being able to communicate non-visibly without giving away our position audibly would be a huge advantage (until your predators/competitors

This is very interesting... IIRC previous estimates were about 1m years before DNA degraded too much to extract useful information. This seems to push that back a little bit. Still, a Jurassic Park scenario is impossible. Even deeply frozen

Do you have some evidence for this assertion? Because Apple happens to make its own GPUs and shading language... a shading language that also runs on other people's GPUs. Seems like relevant expertise to me.

How is that any different than Nintendo's first-party games? They don't pay a license fee to themselves (and such an action would be a pointless accounting fiction if they did). When you buy a Switch it means you can only play gam

The argument for RISC was that the CPU was simpler but could be made much faster. That proved to be overly simplistic. Like the rest of computing it was solved with another layer of abstraction, where CISC processors break instructions into

This is well-known now. Epstein cultivated powerful connections deliberately to insulate himself from scrutiny. It seems likely that he deliberately put politicians and famous people into compromising positions to ensure their cooperation (

Have you run a test recently? Trivial mach IPC round-trip (same process) seems to be about ~8.5µs in my test, so around 4µs per call. I'm sure if you transferred port rights, memory, etc the cost would go up. edit: I would advise anyon

The multiplication can end up turning that large negative number into a small positive one, likely giving you a chance to smash the heap later on (depending on exactly how the int is used).

In theory the standards committee could decide to add _array_ref to the language (or some variation on pointer+length). &myArray[10] could create an _array_ref where sizeof works against it and attempts to take a slice past the end of t

If a minuscule number of people buying your hardware ever run linux, would you waste even one week testing support for it? Would you waste even a single EFI engineer's time on it? What if it were 0.1%? Or 0.01%? What leads you to belie

Any language or system sufficiently detailed to accurately describe the steps necessary to solve the problem turns into a programming language. A very large number of companies have tried to automate software development with little success

Because simplistic policies like this can never satisfy everyone. On a server the process using the most memory might be the mail server so killing it is a bad idea... unless it normally never uses more than 2GB and for some reason it’s eat

It is entirely possible the capacity for this existed but was not being used. That would explain why it spread so rapidly... perhaps most humans already had the capacity?

That's not even remotely true. I've addressed it many times here in the HN comments. I'm just tired of repeatedly giving the same explanation over and over.

If the US Government succeeds in requiring a backdoor then so will every other government. Does anyone really think China won’t immediately demand backdoors?
