English's two most common other intensifiers, "really" and "very" (verily), got their start the same way.

It's not but the Great Vowel Shift happened after spellings were standardized and was a pretty big change. For me the worst part is that my last name, Clough, was originally spelled that way to indicate it used English's guttural

Yes, but nuclear reactors carried up to space for rockets or electricity can still make sense. Before you turn on your reactor it's not very radioactive, to survive to the present day uranium has to have a very long half-life which me

And the Navy puts money into fusion research for that reason, including a bit into cold fusion just in case. But that's not what their doing at NIF, those guys are trying to figure out if you can make a thermonuclear bomb with just ch

Yeah. I, personally, benefit from swappable memory because I'm not afraid to open up my laptop to upgrade the RAM and drive for far cheaper than the official upgrade path. But most people aren't like that and I'm not sure I

AMD's efficiency cores are much more similar to their mainline cores than for either Intel or ARM. Zen 4c cores have the exact same pattern of transistor connections as a regular Zen 4 core, it's just that the transistors much mo

C++ is the language that I know the most things about, but I would never say it's the language I know the best because there are so many things to know about it.

I think a lot depends on what you think a "unit". If you use a leaf function as your unit I think that that's often much too low level but larger modules with relatively stable interfaces can make good units that are product

In general, a person's performance in their job is the best evidence for their future performance, followed by tests you can give them, followed by their genes. That's not to say that there aren't pointy haired bosses who co

They aren't claiming A78 performance, they're claiming A78 performance/frequency. Since there are microarchitectural tradeoffs between frequency and IPC in terms of things like how many FO4s to use in pipeline stages these c

In the robotics world it's pretty common to have something that looks a lot like microservices as an organizing principle. ROS[1] would probably the robotics framework that everybody cuts their teeth on and in that you have a number o

No way a VC is going to be satisfied by something like this. And they're getting to look at the actual budget in any event, no need for vague platitudes about being funded. I'd suppose its for the remaining employees who need re

Yes, in embedded roles. Western Digital's hard driver controllers, NVidia's power controllers, stuff like that and probably a lot more too. Probably more that don't make the news, though this is mostly a thing for companies

Am I right in thinking that the larger load and store queues compared to a Zen core are enabled partially by more relaxed memory ordering rules for A64 compared to x86?

Every square meter of forest absorbs enough CO2 to offset about 1 Watt of carbon fuel use. The average US inhabitant uses about 10kW on average. About half of US energy use is from fossil sources and the population is about 300 million. S

Yup, 128 bit bundles with 3 instructions each, and ways to indicate that different bundles could execute in parallel.

Right, and I mentioned RISC-V as yet another sane RISC architecture that requires word alignment in instruction access. But the fact that it requires alignment means that the word size has implications for the instruction cache design and

Not all JIT spraying relies on byte offsets to get past JIT filters, the attack I gave is just an example. And NanoMips requires instructions to be word aligned just like everybody else, it's just that it requires 16 bit alignment rath

AArch64 does the same thing. https://valsamaras.medium.com/arm-64-assembly-series-branch-... And it's not only a way of decreasing code size. It help with security too. If you can have an innocuous looking bit of bin

Once you're moving to alignment within a larger fixed width block you don't even need to stick to byte boundaries. I've got a toy ISA I've played around with that breaks 64 bit chunks into a 62 bit instruction, a 40 and

Under a classic RISC architectures you can't jump to non-aligned addresses. That lets you specify jumps that are 4 times longer for the same number of bits in your jump instruction. Here's MIPS as an example: https://

That's true in principle, but in this case I think that the existence of search engines is a net social good and I think it would be a big loss for all of us if they disappeared. Not that the days of web rings and hand-curated website

I don't think it's reasonable for Google to remove content whenever someone just says its defamatory, in the absence of a court finding that it's actually defamatory. Otherwise we'd quickly lose every reference to Biden

Is there anything standing in the way of people making open source cores that would be binary compatible with a modern POWER core? I love RISC-V's inroads in embedded, research, and education but I'm a bit skeptical of it succeed

The relationship between frequency and power consumption is very far from linear. The 29W core is running at twice the frequency of the 3.6W core.

This is making me really leery of the sort of Bard Gmail integration that Google has been talking about.

I did pre-order one, but that involves accepting that the money might not end up being a waste.

I'm sort of assuming this was an attempt to tap the cables that went badly.

What does adding extra staff to a late project do? In cases where the procedures are complicated, which I'd be willing to be this is, you might find that it takes the better part of a decade for new staff to come up to speed at their j

Well, all Earth life involves a lipid membrane with a significant potential across it due to a proton gradient. But of course these exist in non-living contexts too or else there wouldn't have been any way for life to evolve. And we
