  • Oggi le persone chiedono ai propri rappresentanti politici, ai propri leader, la rimozione

    Non la fiducia, lo sforzo caparbio, la lotta per migliorare, ma la rimozione
    La rimozione dei propri problemi, dalle difficoltà, dai fastidi della vita

    È questo il vero problema
    È questo che vuol dire vivere, in modo del tutto errato e totalmente sbiellato, la vita
    Vivere una fantasia dorata e rosa da film
    Essere nel paradigma allucinato del consumismo

  • Reverse-Engineering the Intel 8087 Stack Circuitry

    Although something that’s taken for granted these days, the ability to perform floating-point operations in hardware was, for the longest time, something reserved for people with big wallets. This began to change around the time that Intel released the 8087 FPU coprocessor in 1980, featuring hardware support for floating-point arithmetic at a blistering 50 KFLOPS. Notably, the 8087 uses a stack-based architecture, a major departure from existing FPUs. Recently [Ken Shirriff] took a literal closer look at this stack circuitry to see what it looks like and how it works.

    Nearly half of the 8087’s die is taken up by the microcode frontend and bus controller, with a block containing constants like π alongside the FP calculation-processing datapath section taking up much of the rest. Nestled along the side are the eight registers and the stack controller. At 80 bits per FP number, the required registers and related were pretty sizeable for the era, especially when you consider that the roughly 60,000 transistors in the 8087 were paired alongside the 29,000 transistors in the 16-bit 8086.

    Each of the 8087’s registers is selected by the decoded instructions via a lot of wiring that can still be fairly easily traced despite the FPU’s die being larger than the CPU it accompanied. As for the unique stack-based register approach, this turned out to be mostly a hindrance, and the reason why the x87 FP instructions in the x86 ISA are still quite maligned today. Yet with careful use, providing a big boost over traditional code, this made it a success by that benchmark, even if MMX, SSE, and others reverted to a stackless design.

    @SteveClough @cstross I write nothing more creative than documentation for the software I produce, but people misunderstand that, too.The experience of people misunderstanding my docs, or simply failing to read them, was one of the things that turned me away from evangelicalism. (I bet you didn't see that coming.) I wasn't using parables to hint at ineffable spiritual truths in the face of religious persecution: I was just explaining how software worked, how to see its current state, and how to configure and maintain systems. People who were paid to read and understand this material would not or could not do so: their repeated questions made it obvious. Within a very few years, instead of reading TFM, people developed folk stories of commands they could type that usually did something that could be mistaken for success. They veered constantly off-course, and I kept having to drag them back. They consulted each other, rather than the docs, and developed their own mythology about how the software worked. They intuitively felt they knew the software better than I did, because my approach to problem-solving was careful and methodical but they knew a golden shortcut.If concrete, human-level explanations, written out literally, landed so badly, there's no chance that people will have remembered the figurative and unfathomable teachings of Jesus seventy years after his death, written them down accurately and fully, and built from them a useful picture of worlds seen and unseen and the will of God. I'm sorry; it just doesn't ring true.

    Interesting question from: #WritersCoffeeClub day 17: Should modern writers worry about proving their work is not generated by an LLM?My answer: Only if their writing is vacuous. As @kagan writes, the "tells" of AI "writing" are a moving target, but vacuity is still a strong indicator that something is probably written by AI, and if not, that it's almost certainly slop and not worth your time regardless. Just don't write slop, or if you do, don't publish it.
