  • 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

  • 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

  • Honey production is not exactly exploitation free. For instance, queen bees often have their wings clipped or are intentionally killed to be replaced by another

    Moreover, honey production also out competes native/wild bee populations which hurts them. Especially since honeybees are heavily used well outside their native ranges

    We found compelling evidence that honey bee introductions indirectly decrease pollination by reducing nectar and pollen availability and competitively excluding visits from more effective native bees. In contrast, the direct impact of honey bee visits on pollination was negligible, and, if anything, negative. Honey bees were ineffective pollinators, and increasing visit quantity could not compensate for inferior visit quality

  • Yes, it should be banned, but it should be banned nationally. Why focus on the people responding to an egregious behavior? Stop Texas from doing it, then it won’t spread. If they go through and dems don’t respond in kind, the voters will has already been subverted. What are we protecting really but republican power?

    Texas dems have left the state to block quorum (Texas requires 2/3 legislature present to operate) so that Texas legislature can’t put the bill through. Keep the pressure on Text first and foremost instead of focusing rage at the people actually trying to fight back. It’s not a given that any of the response will be needed, but if that is needed, we must do it. If Republicans maximize gerrymandering of every state and there is no counterbalance, our republic will struggle to hold on. There will be no saving of the voter will if a party that wants to destroy it is left to continue holding the reigns


  • This is in response to Texas trying to doing it abruptly 5 years before redistricting. They will do every damn other state with Republican trifectas if dems don’t response in kind

    Taking the high road doesn’t work. Unilateral disarmament is not the move here. It’s either banned for all or none. Republicans have been chipping away at any federal requirements against it for decades and using that to their advantage


  • Saw someone do a rough estimate mapped out all states with current trifectas and found that neither side could lock in a majority if that went to the max and could make maps that went 100% one side or another. Republicans in that scenario have a slight edge, but still 84 seats that wouldn’t be decided by gerrymandering alone (how much of a swing district it actually is may vary). It was a rough estimate so take it with a grain of salt. That also assumed that the states with independent legislative committees all remove said committees and that the Voting Rights Act becomes 100% gutted

    State and local elections are going to matter a lot even if it doesn’t go to that extreme scenario. Make sure to always vote in them. Virginia and New Jersey have important statewide elections coming up this off-year in November


  • Good news doesn’t break through half as much as bad news does. State dems have often (though not always) shown much more resolve to do stuff like this than the national party has

    Earlier this year in Maine, the governor challenged Trump to his face on his illegal attempts to cut school lunch money funding over a single digit number of trans athletes in the state. She won in court and Trump folded and gave the money back

    Earlier this year in Minnesota, a judge ruled a dem wasn’t able to go to office on a technicality (that Republicans only brought up after he won). That seat changed the house from tied to 1 seat GOP, and so Dems then did not show up to deny quorum until after a special election took place. The republicans tried to force operations and operated without a quorum. Dems sued and got a judge to rule every single one of the republican’s actions was invalid because it was without quorum. They then won the special election and only then started back up state legislative operations

    There are people willing to do the work. Show up to every damn primary and vote to make sure they are the dominant force in the party
