Re: M

Some other things are massive caches (192+128K L1, 12MB L2 per four cores, plus Shared memory cache between processor), shared memory between CPUs and GPUs, massive out of order capacity, up to nine instructions per cycle). Just brute force.

Re: Gareth Jenkins and immunity

“I smell a rat” - did you mean that literally?

Re: To Require Alignment Or Not To Require Alignment?

I remember using a processor where unaligned access trapped and was emulated in software. Fine if it happens once. Bad if you allocate an unaligned array with a million integers. A million traps slows you down.

Re: "the only figure that really matters is hospitalisations"

Living “in a state of anxiety” is stupid. Especially when you realise that anxiety is what motivates anti-vaxxers and the “it’s just a cold” brigade.

But being aware how much or how little you are at risk lets you make the right decisions in life. For me it’s getting vaccinated regularly, Covid risk is not high enough for me at the moment to make lifestyle changes, but high enough to get vaccinated. Not doing so would be stupid.

Re: There's an Ignobel prize here ....

Survivor bias. Literally this time. Those that are still identifiable landed in a way that caused the least damage.

Re: Something About...

The boss pretends to be a supporter of unlimited free speech. So if he fires people for their speech then he’s obviously a hypocrite, liar and scumbag.

Re: ALGOL 68 Blew My Mind

“Call by name” is back in Swift as “autoclosure” arguments. Instead of passing a value, the caller passes a closure that the callee can evaluate.

How it is used was probably not what Algol68 expected. It allows to make || and && part of the standard library instead of the language, same with asserts or logging statements.

Re: Driver and insurance should pay

Your “sack of meat” chauffeur is the driver and responsible. A box of electronics is not a driver. That’s why I would be responsible.

Re: PostIt Note Security

In the USA, any password protection that you break means you are in breach of the DMCA, which may give your company access to higher damages. However, changing the password every month is not needed for that.

Re: At which point....

>If I write a bestselling book, I don't see why my great-great grandchildren should be entitled to royalties from MY work, but that's the current situation

It’s most likely that you didn’t get paid a decent amount per hour of work that you spent on writing. With books, music etc. you don’t get paid on delivery, you get paid a percentage as long as your work sells and makes money. So if I wrote a book, I intend to live another twenty years, and it is so good that it still makes money after 20 years, then I haven’t been paid completely yet. So yes, I want that money to go to my heirs.

Re: Twice!

Oh well. I was on a flight from Germany to London (not Concorde). It was the second flight of that airplane and it didn’t take off. Some computer problem. The pilot turned it off and on again. Never before or after have I been in an airplane that was turned off. Completely. No lights, no sound, nothing.

Re: "Why bother with security checks", said Intel

That is a completely wrong description of the bug. A register is speculatively overwritten, and when the speculation is found to be incorrect, it must obviously be restored. It is not restored correctly with the data that was overwritten but with data in a rename register from another application. There are no permissions involved.

Re: I must be a bit thick

I didn’t write code for that. Metrowerks wrote it in their release notes. Loop optimisation didn’t take into account that unsigned char c++ wraps around.

Re: Credentials after leaving

At one place, there was some never used account that got totally forgotten and my phone was registered for 2FA. So I got a call from the company half a year later when someone tried to do a password reset, and I read the 2FA code to them.

My appleid and password allow to do lots of things. That is not something you would ever hand over to anyone but apple. It’s not an iMessage account, it’s an everything apple account.

Re: Both

Also directly connected to the GPUs, so there is no copying of data between CPU and GPU.

I would think that measuring and charging per usage might be costly as well. And you will get complaints from people who think they were charged too much. And I don’t know how much the fact that I have a connection costs my ISP.

It’s quite conceivable that correctly charging for usage would cost more than just delivering what’s needed.

This isn’t covered by DMCA at all. Just like Lexmark wasn’t protected by DMCA. They are not copying anything that is protected by copyright.

Re: Slap On The Wrist

No punishment for this guy will prevent further cases. Because whoever does that kind of thing is an idiot who doesn’t think about the consequences.

What CEO would do that?

Re: How was it basically the VPs fault?

It’s easy to see when you know the problem. If you don’t know, then it’s a lot harder.
