  • So if i created my own keyboard from scratch on a open hardware microcontroller, could i implement this?

    The USB controller that interrupts the CPU lives on the other side of the connection, so you’d just be building hardware that responses to the polling. If you’re curious what that looks like, Ben Eater has a cool video looking at what that looks like for a USB 2 keyboard https://youtu.be/wdgULBpRoXk

    There’s also the case of Bluetooth dongle keyboards not working in UEFI (except that one) but USB always do. Is it this or just the UEFI not having drivers?

    I am no USB Keyboard expert, but through the power of looking it up it seems like most of these do not operate as a HID (human interface device, like mouse and keyboard) so need driver support, but some start up with a basic HID proxy which might be you have one that works. From an older thread about BIOSes rather than UEIFs

    A keyboard using Bluetooth cannot access the BIOS. Logitech Bluetooth keyboards get around this by having a dongle that pairs with the keyboard in a more basic, non-Bluetooth mode until the driver kicks in and switches modes. Microsoft might be similar mode with their keyboards and dongles, but I cannot confirm that.

  • Technically, interrupts are still often involved… just from the USB controller on the state of the polling instead of the keyboard directly on a keypress


    Some keyboards implement the USB Boot Keyboard profile specified in the USB Device Class Definition for Human Interface Devices (HID) v1.11 and are explicitly configured to use the boot protocol. These are limited to 6-key rollover (6KRO) and will interrupt the CPU every time the keyboard is polled (even if there is no state change) unless the USB controller is programmed to tell the keyboard to respond with negative acknowledgments, which the USB controller discards in hardware without interrupting the CPU, when there are no state changes to report

  • Starting this off with: I am not an epidemiologist and most of the epidemiologist I’m seeing online aren’t yet too concerned

    That being said, they have not found any rodents on the ship, though that does not mean they didn’t just miss them in their search. The version on the ship has been confirmed to be the Andes Virus (ANDV) which is human-to-human transmissible in a way that most hantavirus are not

    It’s hard to say exactly how the virus will behave outside of a cruise ship (which are known for spreading diseases more than other locations), but we can potentially look at a past outbreak in 2018 in a small town for an idea

    In this work, we described the isolation of the strain responsible for the largest ANDV PTP transmission outbreak, which occurred in the small town of Epuyén and began on November 2, 2018. This strain, ARG-Epuyén, exhibited a high capacity for PTP transmission, necessitating the implementation of quarantine measures to curtail further spread [8]. The median reproductive number (the mean number of secondary cases caused by an infected person) was 2.12 before control measures were implemented and subsequently dropped to below 1.0 by late January

  • This is mostly greenwashing and false hype by the beef industry with misleading numbers

    What’s more, feeding cattle algae is really only practical where it’s least needed: on feedlots. This is where most cattle are crowded in the final months of their 1.5- to 2-year lives to rapidly put on weight before slaughter. There, algae feed additives can be churned into the cows’ grain and soy feed. But on feedlots, cattle already belch less methane—only 11 percent of their lifetime output

    […]

    Unfortunately, adding the algae to diets on the pasture, where it’s most needed, isn’t a feasible option either. Out on grazing lands, it’s difficult to get cows to eat additives because they don’t like the taste of red algae unless it’s diluted into feed. And even if we did find ways to sneak algae in somehow, there’s a good chance their gut microbes would adapt and adjust, bringing their belches’ methane right back to high levels.

    […]

    All told, if we accept the most promising claims of the algae boosters, we’re talking about an 80 percent reduction of methane among only 11 percent of all burps—roughly an 8.8 percent reduction total

  • If the filibuster is removed, it is also possible to get through with 50+VP as tie breaker or 51. The filibuster being removed is not as unlikely as you may think since Republicans right now are getting closer and closer towards defacto removing the filibuster. There currently are narrow ways around the filibuster (reconsideration is one big one) that are supposed to have a bunch of limitations, but they are testing the waters in ignoring violations of those limitations. The senate parliamentarian is the one who makes rulings about if something violates their clauses, but their opinion can be ignored by a strict majority via the “nuclear option”

    A month ago, Republicans used the nuclear option to ignore the senate parliamentarian ruling that the Congressional Review Act would not allow them to skip the filibuster to remove California’s EPA waivers (see here).

    As I write this Republicans are currently trying to play another different a different trick about some of the stuff in the Big Beautiful Bill. Dems have been challenging a bunch of provisions and getting the parliamentarian to most of the time rule they are in violation of the Byrd rule. But they are also trying to challenge the whole bill as violating the Byrd rule’s limit that a bill passed via reconsecration cannot increase the deficit over a ten-year period. Republicans are playing an accounting trick to claim it doesn’t. They know the parliamentarian is unlikely to agree with them, so they are currently trying to prevent dems from even being able to ask the parliamentarian about it









  • Maybe, maybe not. Don’t assume it’s a given that they will ignore it. This is not a defense of this administration. This is a reminder against always having the hopelessness that this administration wants us all to have. They want us to assume all fights are hopeless so we don’t fight them

    While they have very notably been ignoring the order on Abrego Garcia, they have followed some of the court order in other related cases like this

    For instance, a week ago ICE released Columbia pro-Palestine activist Mohsen Mahdawi from detention after a judge ordered immediate release. Here’s a photo of him leaving







  • For the moment in the current AI boom, but not expected to in the long run. Just make the progress less fast. Still not ideal, of course, but don’t get into the mindset that we can’t make any progress at all when we still can and are doing so

    From the article

    Ember’s report shows that clean generation growth is set to outpace faster-rising demand in the coming years, marking the start of a permanent decline in fossil fuel generation. The current expected growth in clean generation would be sufficient to meet a demand increase of 4.1% per year to 2030, which is above expectations for demand growth.
