  • @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.

    Today is Data Privacy Day 🔒✨On this day, remember that privacy isn't some luxury we can live without. Privacy is a fundamental right that is essential to safety, to community, to freedom of speech, and to democracy.Authoritarians are trying to undermine our privacy rights because they are well aware of this. Do not let them ✊This year, let's fight for our privacy rights like we never did before. So many of our other human rights depend on it 🔒💚#DataPrivacyDay #Privacy #Democracy #DigitalRights #HumanRights

    @paraplegic_racehorse Excellent point! The article explicitly acknowledges this: AI doesn't 'choose' Markdown intentionally—the pattern emerges from training data (GitHub, Stack Overflow, technical docs). Org-mode is indeed equally human-readable, but its smaller footprint in training corpora explains the difference. This actually reinforces the broader point: format adoption creates network effects that AI amplifies.

    European tech companies should demand stronger regulation, especially on privacy!Why? Because it would give them an advantage over their US-based competitors, who are neither willing nor able to operate under strict rules.That's why the European Commission's Digital Omnibus package is such a bad idea. Weak regulation doesn't create a level playing field for all. It benefits the big and powerful players more than anyone else!--#privacy #DataProtection #GDPR #DigitalOmnibus

    Today October 21st is Global Encryption Day! 🔒🎉This is a good time to remember that encryption is essential to online security and digital privacy. Despite some governments pushing hard to weaken it, we must remind them that we all need encryption, and especially end-to-end encryption, to stay safe online 💚Privacy is a human right and end-to-end encryption is one of the best tool we have to enforce that right. https://www.privacyguides.org/articles/2025/04/11/encryption-is-not-a-crime/#GlobalEncryptionDay #Encryption #E2EE #Privacy #RootForE2EE
