It's far worse than you make it out to be. Max internal clocks on DDR4/5 are about 400MHz. There's a fundamental limit (rapidly diminishing return) to how fast you can drain and charge capacitors. They try to make up for it b

Golden Cove is a much wider core than Zen 3 and has decently higher IPC. I'd guess Zen 3 is faster at base clocks, but I believe the 12900H doesn't stay at base clocks very often.

Do you know where there's any hard data on the actual speed of AMD's USB4 implementation in the 6xxx series? Everywhere I've looked, I get "USB4" then a blurb that USB4 can be "up to 40Gb/s" with the

If you know C, it doesn't mean you are any good at Haskell, Prolog, Forth, Smalltalk, Lisp, or any other major paradigms. All of those introduce fundamental concepts that the C programmer simply does not know (I recommend learning all

Put a JS dev and a C++ dev of equal experience against each other and the JS dev will have fewer bugs. At the most basic, the JS dev would have all the same logic bugs as the C++ dev, but subtracting the memory bugs from the JS bug count wo

It’s not a “gray zone”. Derivative works are flatly covered by copyright law and this definitely doesn’t meet any of the fair use criteria either.

Qt development with C++ is slow. Development with QML means JS anyway (good luck finding JS devs with Qt experience) and still having to hire C++ devs too for non trivial apps.

The issue is UI jank and occasional UI slowness. If there’s any serious work, it’s probably implemented natively or with WASM, so computational performance isn’t terrible.

I know TONS of people (including high paid people) who refuse to pay $3 for a good app and instead opt for the free knockoff with tons of jank and nonstop ads.

I can write as much of a project in a day using JS as a C++ dev could write in a week or more. My code will have fewer defects and more critically, will be 100% free of the worst kinds of defects that C++ enables. Sure, my code will be 2-10

VLIW has nothing to do with width and everything to do with explicit ILP (instruction level parallelism).

AMD's latest RDNA3 is explicitly VLIW with the VLIW instructions working on SIMD units. Ironically, they are also running head first into the compiler issues with almost nothing around taking advantage of their dual issue potential.

Fun fact: Intel had a couple CPUs codenamed Tejas that were going for 50-ish pipeline stages and 7-10GHz before being abandoned as basically impossible. https://www.youtube.com/watch?v=qzZfkbHuB3U

The halting problem means that for typical programs, you can't prove control flow. Proving optimization means not only proving control flow, but then knowing which branches get taken most often so you can optimize. There may be a sma

Intel bought Alpha from HP/Compaq. The biggest reason Alpha was a "workstation" chip was margin and R&D issues. It was fast, but they couldn't manufacture in high volume which drove per-chip costs much higher than th

If developer time is worth just $50/hr, that's just 20 hours to pay for itself. Pugetbench says 448 seconds for the Threadripper 3990 to compile unreal vs 889 seconds for the Ryzen 5950X. That's over 7 minutes saved every com

Structural typing works very well in StandardML (and in Ocaml these days too). It's not structural typing, but how you use it. One of the biggest benefits of structural typing is how you can have most of the ergonomics of untyped langu

Apple switched from ARM Cortex A8 to A9. There were a lot of improvements. The change from in order to out of order was huge. L2 cache doubled to 1MB. Memory bandwidth doubled. The FPU got properly pipelined too. RAM also doubled to 512MB.

SwissMicros make really good devices if you’re willing to pay the price. I carry my HP42 clone everywhere. They make a clone of the programmer HP-16c that is pretty nice. Everything is open source too, so there’s modding potential if you a

Why no mention of safety? On the whole, the type safety guarantees of something like StandardML over something like Golang are at least as valuable as many of the more traditional "functional" aspects.

Most Schemes have a very large standard library, but you have to know that the standard library is referred to by SRFI -- a bunch of random numbers rather than names. They don't list docs either. You have to know that you must go to th
