  • @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.

    What do you think of using Google in your life?I use a Google Pixel 7 Pro at the moment, but I use GrapheneOS instead of OEM, and I think it is the best Android line of phones I have used so far. Their bootloader is lockable after installing custom operating systems which is much better than all other offers at the moment. The build quality, battery and design of the phone is solid as well. This phone has a lot of merits going for it which other Android phones are not replicating for the sake of a false sense of "security" or profits. I will appreciate Google for giving me a great phone to install GrapheneOS on, alongside Android for being a secure base for an operating system.I appreciate the Chromium browser more than other browsers in the market. While Google Chrome is junk regarding user privacy, as well as shoving AI in your face, Chromium itself is actually pretty solid. It is also the most secure option, offering a malloc() implementation better than Firefox's mozmalloc, although not as secure as hardened_malloc, by GrapheneOS. Firefox is also implementing AI features into their browser, which leaves a bad taste in my mouth. MV2 is deprecated, sure, but you win more than you lose in security, as a lot of API features were exploitable. Chromium does a lot of good things, while Chrome gives the base itself a lot of bad blood. I would like to see what Servo can do, but I appreciate Google for making a secure browser.I generally despise a lot of what Google offers, however. I feel like they lean heavily on the deception of convenience, where Google gives really good results while it uses your data for the sake of advertising. This applies with the Google Suite (Mail, Office, and Drive among others) as well. I would much rather use FOSS or nonprofit alternatives, such as Tutanota, or LibreOffice. Google is essentially the serpent from The Book of Genesis, selling you the benefit of their convenience for the sake of having your data stolen for their use. As such, I will choose not to follow Google convenience promise for my security.Feel free to leave your opinions, and why I should consider other avenues rather than accepting a bit of Google in my life. As much as I love privacy, your privacy can't be guaranteed if there is no good security. Google may be known for piss-poor privacy, but their open source projects have a lot of security merits as well as good privacy. Do not use this as advice, but make your own conclusion.#google #privacy #security #grapheneos #chromium #technology #FOSS

    Bill C-2, the so-called “Strong Borders Act,” is a dangerous rollback of Canadian rights. It hands the government sweeping, warrantless surveillance powers, threatens privacy, and bows to U.S. pressure. This isn’t leadership — it’s a betrayal of our freedoms. Speak out now to stop this anti-rights, anti-privacy, anti-Canadian bill before it’s too late.https://openmedia.org/Stop-BillC2-em#Canada #CanPoli #Privacy

    I blocked the `threads.net` server as an admin of this server because I recently quit Meta. This is also to free myself from Meta's influence. Additionally, there are many media reports about Meta's misuse of minors' pictures as part of their targeted advertising campaigns. My AI chatbot reported a summary to me, indicating that Meta even defended this behavior, claiming that they had appropriate agreements in place. #Fediverse #Privacy #Safety #DigitalFreedom #OnlineSafety #Meta #Threads #Decentralization #DataPrivacy #DigitalRights #Blocklist #FreedomOnline #Transparency #UserControl
