  • @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.

    Surveillance Watch – Una mappa che mostra le connessioni tra le aziende di sorveglianzaLe tecnologie di sorveglianza e gli #spyware vengono utilizzati per prendere di mira e sopprimere giornalisti, dissidenti e difensori dei diritti umani in tutto il mondo. Surveillance Watch è un database interattivo che documenta le connessioni nascoste all'interno dell'opaco settore della sorveglianza. Fondata da sostenitori della privacy, la maggior parte dei quali è stata personalmente danneggiata dalle tecnologie di sorveglianza, la nostra missione è quella di far luce sulle aziende che traggono profitto da questo sfruttamento. Mappando l'intricata rete di aziende di sorveglianza, delle loro filiali, partner e finanziatori, speriamo di svelare i facilitatori che alimentano le diffuse violazioni dei diritti in questo settore, garantendo che non possano eludere la responsabilità per la loro complicità in questi abusi. Surveillance Watch è un'iniziativa promossa dalla comunità e ci affidiamo ai contributi di persone appassionate della tutela della #privacy e dei diritti umani. https://www.surveillancewatch.io/@privacypride #SurveillanceWatch
