Not even mentioning Brexit, possibly the single biggest change in the fundamental economic underpinnings of the UK in the last 50 years, feels deliberately misleading to me. Living in Britain right now, I can tell you nobody I've met b

I feel like AMD having their "eco mode" is a pretty good solution - it allows the user a pretty easy method of deciding if peak performance or efficiency matters more to them. Better than a separate SKU for each. Though this comes

Caches are also very much size-constrained. Compressed instruction formats phase in an our of favor to this day, trading size for decode complexity.

Things like CMOV were introduced in the pentium pro (i686), which often is the cut-off for reasonably modern OS support.

If you're not using every possible construct in unsafe rust blocks, then you're not using rust - just a safer language that just-so-happens to be a subset of rust. The difference is that "discouragement" is in the compil

Lumping C and C++ together implies much about the use of the language - "modern" C++ features go out of their way to avoid memory unsafe and bug-prone operations (avoiding raw pointer arithmetic, no manual new/delete memory m

Imagination Technologies sold off MIPS in 2017 [1] - while RISC-V might have been a thing back then, it was certainly nowhere as known as it is today, and well before any decision to focus on RISC-V. Interesting in that Imagination have sin

Power use tends to scale non-linearly past a point - disabling turbo modes would likely significantly reduce the peak power use, and ~18% performance differenceis pretty big buffer to lose. The 6850u also beats it rather comprehensively acc

Many mp3 encoders cut off really high frequency stuff - somewhere between 16khz and 20khz depending on the encoder. Often this isn't changed by any of the quality settings, e.g. on lame it's still enabled on the "insane"

Only if it's more efficient than the alternative. It may be that having special cases and extra complexity has a higher overhead than just getting everyone to use the same path, even if that looks like "more" work from a dist

That's just a way of estimating that is likely quite accurate in a completely steady state. But what if you know you're changing things significantly, and that's the whole point you need to think about resources and schedules

Aren't "Machine Readable Specs" a programming language?

Maybe? If you just round up each "object" to 4k then you can implement this using the current PTE on x86_64, but this removes the (supposed) advantage of only requiring a single PTE for each object (or "object cache" loo

The other option is to use those 64bits to double the total bandwidth in the "Traditional" page-table system. All this extra complexity and bus width doesn't come for free, after all, there's opportunity cost.

I'm a little confused about how the object base is looked up in these systems, and if they're sparse or dense and have any size or total object count limitations, and if that ends up having the same limitations on total count as p

While the temperature is rather wide, I would expect the actual energy difference to be relatively small, as without atmosphere for convection and little conduction down due to the insulating properties of regolith it may end up heating jus

I feel that may be biased, as presumably every lemon buyback from Porsche gets resold on the second hand market, but clearly not all cars from a 2020 model will have resold yet. I'd even go as far to say that the majority of a 1-2 ye

I feel that there's a type of person who invests $320,000 based on a facebook ad into something they didn't understand. I don't want to disparage them, but it feels like it was a matter of time before they lost that to some s

I certainly agree - it was about 10 years ago now, but I did a physics degree and ended up pivoting to computer science. I offered to help a couple of friends in the department with their analysis, and ended up writing the majority of their

On an android device I worked on some 5 years ago (so might be out of date) it used a simple cpu mask. Background tasks always used only the little cores, foreground apps always always used only the big cores. I do not believe it was possib

My understanding is that with current generation GPUs a crash/timeout can happen. Again, you can do pretty much anything with shaders, so invalid accesses, infinite loops, other things that can halt execution are perfectly possible. It

All modern GPUs (Or at least both I've worked on professionally) have MMUs and some context privilege level (IE so contexts can't change the MMU state themselves to escape) in hardware. If that is busted all bets are off, similar
