    Friendly reminder that the encryption used by bluetooth has had multiple security flaws discovered in the past, and even if it were perfect, transmitting a burst of radio energy on each keypress invites the possibility of timing attacks.

    Wireless makes sense for mice, because they have to be moved around, but the only good reasons to have bluetooth on a keyboard are Android and set top box media center PCs.

    It's less a kernel bug than a bad firmware decision on Keychron's part. Keychron's non-QMK keyboards all use the USB vendor/product IDs from a 2009 Apple keyboard; the "bug" was that the kernel expected them to actually behave like the device they claim to be.

    Anyway, wild seeing a Phoronix article about something I did again after all these years.

    I found that the bluetooth went to sleep way too quickly so I disabled the auto-sleep and it's been a lot better since then. I think you can toggle it by holding `fn+S+O` for a few seconds.

    Just some notes/opinions: I currently have an opto-mechanical keyboard with linear "red" switches. In my experience, from the viewpoint of typing speed and precision, tactile clicky "blue" switches are the best option and tactile "brown" switches are a very good option, while linear "red" switches are the most error-prone of these 3 options when typing text. I don't use keyboard to play games. Despite the fact that I estimate the lifespan of the "red" keyboard to be 10+ years because of its good build quality and absence of metal parts in the optical switches, I suspect that I will switch to "blue" or "brown" switches before its lifetime expires.
    Blues are fantastic and my second choice for typing, but IMHO, Box Whites are even better. Been using the Box Whites on my Ultimate Hacking Keyboard v2 since a few months now and they are everything Blues are, but better.

    You can put "options hid_apple fnmode=0 swap_opt_cmd=1" into a conf file in /etc/modprobe.d to get it working currently. The change is to make it automatic from a manual setup.

    The picture does show "Linux", but the description reads:



    Where. Is. Linux! It's not an alien operating system!
    there are enough of us that dell, etc, took notice. i can't remember how many builders.. but our numbers aren't shrinking. i myself was looking at one of these to replace my still-technically-working lycosa. i love me some flat/low-profile short-throw keyboards, and there are so few worth considering.
