If it was just for aesthetics, you could have just a discreet manual release. Anyway, you don't have "a discreet manual release" on actual implementation of that crap, so yeah that's the point: you could and you should h

Expected by who? Those who have access to private info? As far as I'm concerned, I don't see why I should expect anything less than 100% usage if a vendor does not warn me otherwise, and countries exists where mandatory warantee i

Does it still need to be allowed by specific chipsets, though ?

IIRC Intel "consummer" parts are qualified for 3 (or 5 ?) years of usage at a 30% duty cycle (and you might not find that figure publicly, but honestly you should, and intel should be mandatted to publish it). Now that is likely n

I love how only some are providing the protection of not being fired for following the law. Can they order you to organize a coup, some terrorist acts, or a murder in the others?

If you exclude everything that does not go into your direction and make the hypothesis that a poor architecture would have risen and then would not have been replaced, you conclude that "everybody" would use it?

by temac 4y ago
It was a poor architecture though and if not by AMD64 it would have been killed by something else more in line with traditionnal high perf superscalar. Maybe even just Arm.

> Intel has tried to move away from x86 three times already Also, they tried to move to other ISAs they owned. Trying to move from their position to 3rd party or open ISAs would make even less sense.

Using unitialized values is UB. Going back to naive pointers is a lost cause because compilers have started to do crazy optims (not even currently allowed by the standards...) like origin analysis. You can't steal that toy from the peo

by temac 4y ago
Current compilers don't "tell you to stop". They silently transform your program into complete garbage without even causality restraints. The sanitizers can help but they are merely dynamic when the dangerous tranformations a

Undefined behavior is probably the worst way we can imagine to define constraints usable by optimizers. Sad that major languages and implementations went this way.

You don't need billions to be a private leader. Or you shouldn't.

Some of the bugs and ergonomics problem you describe seem dangerous. The regulators should come in and ban those cars until they are fixed.

Interesting but I'm not sure about the relevancy to the above comment. On a sidenote, it has weird claims: > obviating the need for ownership type systems or other compiler approaches to fixing the type-safety of use-after-frees. Th

That does not "solve" plugins. That does not allow bugfixes in libraries. Edit: and worse, that's introducing plugin like problems in code that does not even use plugins. Next idea?

A thing that does not exist, still is leveraged to build whole distros, and its too high stability resulted in the creation of Carbon.

The funny thing is that long mode can actually support win16 applications, and Wine does it.

The standard doesn't do that often, but it does sometimes. E.g. realloc to null which was previously defined, and is now UB :(

Debian is taking care of security maintenance of the software they ship. Now: maybe they will do a poor job of it, but that's another issue than intent; some users misdirect support requests to the upstream, but unless Debian version i

Even win 3.1 did that in a mandatory way with it dropping support for Real mode, and Standard and Enhanced were available for windows 2 already. And Windows applications of that era went through Windows API and Windows drivers, not DOS ones

Do Linux distros support hiDPI including mixed DPI (e.g. with a hiDPI laptop screen and a low DPI external one) well ? Under macOS this works really fine, under Windows this is half garbage.

The Windows default can cause problems because of simple logic bugs. The Unix default can cause unsolvable problems because of races between threads. You should use CLOEXEC everywhere. Except you can't because you are using libraries.
