  • @skua @markhurst There are lots of confounding variables other than laptops and tablets, yet we always see articles like this and almost never on the other factors. Yeah, a lot of this predates Covid, but there is a general lack of willingness to even consider or acknowledge the effects of this disease on children and the culpability that schools, school boards and society at large have in not making every effort to reduce exposure in an environment they are forced into.

  • @skua @markhurst Show me graphs of Maine's classroom teacher to student ratios for the last fifteen years. Show me teacher pay and average educational achievement. Show me child poverty rates. Show me data on kids needing food assistance and whether they are getting it. Show me vaccination rates.

    "Fortune reported in 2017 that Maine’s public school test scores had not improved in the 15 years the state had implemented its technology initiative."

    Test scores not improving in Maine for 15 years prior to 2017 is hard to attribute to the neuro-disruptive effects of COVID-19.

  • How the Intel 8087 FPU Knows Which Instructions to Execute

    An interesting detail about the Intel 8087 floating point processor (FPU) is that it’s a co-processor that shares a bus with the 8086 or 8088 CPU and system memory, which means that somehow both the CPU and FPU need to know which instructions are intended for the FPU. Key to this are eight so-called ESCAPE opcodes that are assigned to the co-processor, as explained in a recent article by [Ken Shirriff].

    The 8087 thus waits to see whether it sees these opcodes, but since it doesn’t have access to the CPU’s registers, sharing data has to occur via system memory. The address for this is calculated by the CPU and read from by the CPU, with this address registered by the FPU and stores for later use in its BIU register. From there the instruction can be fully decoded and executed.

    This decoding is mostly done by the microcode engine, with conditional instructions like cos featuring circuitry that sprawls all over the IC. Explained in the article is how the microcode engine even knows how to begin this decoding process, considering the complexity of these instructions. The biggest limitation at the time was that even a 2 kB ROM was already quite large, which resulted in the 8087 using only 22 microcode entry points, using a combination of logic gates and PLAs to fully implement the entire ROM.

    Only some instructions are directly implemented in hardware at the bus interface (BIU), which means that a lot depends on this microcode engine and the ROM for things to work half-way efficiently. This need to solve problems like e.g. fetching constants resulted in a similarly complex-but-transistor-saving approach for such cases.

    Even if the 8087 architecture is convoluted and the ISA not well-regarded today, you absolutely have to respect the sheer engineering skills and out-of-the-box thinking of the 8087 project’s engineers.

    "Question. For many years, you’ve been trying to get U.S. technology companies to process the data of European citizens according to EU standards. Is that possible with Trump in the White House?Answer. A legal system has to be stable precisely in situations where you have a crazy president. If everyone were nice and friendly, we wouldn’t need laws. A big issue is how much the whole data economy has become part of this trade war. One of the only things that Europe can retaliate [against] is going to be the digital industry. It’s one of the things where [Americans] make shitloads of money. It’s the financial industry, digital industry… and that’s about it.The [EU] Commission just fined Meta and Apple… and the former responded with a very Trumpian press release, saying, “Oh, this is a tariff.” You broke the law and you knew you were doing it, so now you can’t just say it’s a tariff. It’s like someone driving their Porsche at 180 miles an hour and, when they get fined, they say, “Oh, you just hate rich people.”Q. Is the European Commission right to fine two tech giants in the middle of a tariff war?A. The EC is taking things slowly, because it doesn’t want to be the first to throw a stone. But at some point, you have to enforce your law. We must address the issue of technological dependence. In the U.S., there’s even been talk of American companies not offering their services in Greenland and Denmark. It’s crazy, because then no one would trust those companies again… but we also thought no one would ever start a trade war."https://english.elpais.com/technology/2025-09-13/max-schrems-jurist-the-promise-of-the-cloud-was-that-everything-would-be-much-cheaper-but-it-turns-out-that-it-functions-as-a-monopoly.html#EU #GDPR #Privacy #DataProtection #Cloud #CloudComputing #BigTech #DigitalSovereignty #USA
