  • S3 is what people actually think of when they think of sleep mode, or modern standby. The running state of the operating system is stored in RAM, in low power mode. All context for the cpu, other hardware like disks and network is lost and those devices are completely shut down - bar the RAM. Basically, you close the lid at the end of the day, and you’re nearly at the same charge level the next morning.

    This saves a lot of power. On my older 8th gen intel cpu laptop, it loses maybe 1-2% charge per day in this mode.

    My new 13th gen laptop still has deep sleep, or standby (s3) as a hardware function, but it’s technically not supported. It actually doesn’t work when enabled, and just falls back to s1 (sleep, everything’s still on, just in low power mode). It loses about 2-3% per hour in this mode

    S4 (Hibernate) does roughly the same as S3, but the OS state is stored to the disk instead of ram, so that can be shut off too. Now the device is completely powered off, losing no charge while ‘asleep’.

    S5 is off

    S4 sleep takes much longer to wake up from than s3, so was less desirable. In the modern computing world (especially end user devices), commonly there’s full disk encryption going on, which adds a layer of complexity to resuming from disk, as you would when waking up from hibernation (s4).

    Making it resume without putting in a decryption password for example (using a TPM), isn’t simple, and breaks a lot when you do system upgades



  • I can honestly say my space grey first-gen magic keyboard has served me well. It sits on my desk at work, I use it every day, and it only needs charging once every few months.

    The only thing I’ve ever done to damage it is pulling the z key off to clean between the keys, I tried to jam it back on wrong and ruined part of the scissor mechanism

    My next keyboard may yet be one of the newer models, but it’s to expensive to pull the trigger yet.

    Having tried it in person, I’m also considering the logitech mx keys mac variant. I didn’t even notice the key shaping while actually typing, and it’s the first keyboard I’d say comes close to being a magic keyboard replacement.

    I like the option(alt)/command(super) switched layout.

    I’ve got a keychron k3 ultra v2 too. I finally gave in on the mechanical keyboard train and splurged a bit - but now:

    • I need a wrist rest, even this ultra low profile version is way higher than I’m used to.
    • I hate the layout (my own fault for buying the most cramped version)
    • On linux at least, bluetooth is not the greatest (sometimes needs a keyboard restart to fix key send delay and repeat keys)
    • I picked the optical (cherry mx red equivelant) switches and they’re mushy af.

    I’ve had the white slim first-gen mini magic keyboard for years too. The battery swelled up, so I removed it and use it wired now. That was probably 8/9 years old.






  • I’d hesitate to call it truly enterprise, but I’ve used the 24 port/10Gbe version of these in a datacenter. Not many issues to write home about - seems to handle vlanning pretty well.

    Has 10Gbe uplinks, US power, and PoE+. Probably access to a fancy dashboard too.

    $1600 is probably as cheap as you’re getting.

    Edit: Oh yeah, they’re probably not dual attached, and the ‘redundant power supply’ (RPS) is a separate appliance, which I consider kinda bullshit, that takes up another U.

    I’ve had no trouble with actual switching performance though fwiw.

    Edit 2: They’re probably compatible with the AR mobile app, which is hella cool, and somewhat useful in customer sites.

  • You’d be surprised. I’ve got a mid-tier i7 laptop from 2017 and it munches through most productivity tasks.

    It’s my i9 desktop that suffers when I’m running everything I want to have up. Between containers and compilers, VMs and videos, tabs and terminals, you can really put the hurt on a machine. I likely won’t be swapping until everyhing has adopted 45, or until I figure out how to make hyprland work the way I want it to
