  • More directly answered, most CO2 lasers are rated in optical output power. There are a lot of inefficiencies before that, so e.g. the 85% efficient power supply, the (wild-ass-guess) 40% efficient laser, then you have other electrical loads like probably at least a dozen watts of fans, substantial power for motors, lights, controllers, air pumps if you have one…

    I would expect a “120w” CO2 laser to have peak power consumption of at least 500w. You can use a kill-a-watt to check out the actual consumption while cutting, frankly I’d probably go with a 750-1200 kVA ups just for substantial fudge-factor.

    Curious if you’ve already bought the UPS and if so how it’s gone?


  • Driving two 4k monitors at 10b120hz is pretty overkill to use thunderbolt for, is kind of my point. Is anyone actually being limited by that?

    Even with cameras, the storage generally isn’t that fast. CFexpress cards cant generally break 2GB/s, and even 8+k cameras generally record to that or maybe USB-C (and if you’re recording to a USBC device you’re probably just gonna use USBC instead of thunderbolt).

    NVMe that can do sustained write speeds like that will be full in a few minutes, unless you’re offloading to a massive high speed array over 10+gbit networking it just kind of seems like why bother?

    Don’t get me wrong, I like the idea of going to faster interfaces for the sake of speed, but I have experienced almost zero real use of thunderbolt in real life, and I usually keep a pretty good eye out. My real question was mostly focused on whether there are people actually using thunderbolt and if they’re actually limited by 40gbps and I’m kinda just bitching at this point



  • Anything besides parts and manuals.

    Requirements for devices to be feasibly repairable in the first place. A phone that’s effectively a brick of glue is still unrepairable regardless of whether you can buy overpriced parts for it.

    If the enforcement mechanism for “fair” pricing is for the general public to file a lawsuit, I can guarantee that pricing isn’t going to be very reasonable.

    Apple devices are notoriously hard to repair not just because they don’t provide a $50,000 diagnostic kit and overpriced parts, they’re hard to repair because they’re designed to be disposable. This bill does absolutely nothing to change that, which is probably why Apple supported it. Good PR with completely avoidable consequences for them



  • Does anything even use thunderbolt 4’s bandwidth? About the only thing I’ve seen is external GPUs and even that is a ludicrously niche use case.

    I’d be much more excited about a post about something using TB4 to its fullest. All I can think reading this title is “who cares?” Is someone going to make a reasonably priced and even remotely convenient 40gbps ethernet card for TB5? No. Do my NVME drives go past 40gbps? Generally not, but I could’ve seen use for fast drives plugged into tb4/5 at least. Is anyone using TB4/5 for datacenter interconnects where this speed would actually be useful? I doubt it.

    Does anyone reading this post use tb4 on a daily basis and feel limited in any way?



  • As someone who also has 15+ years of experience in the field and is currently infosec management, it’s not that bad. Certainly not something I’d say “you’re in for a world of hurt” about like somebody just bought a bad timeshare.

    Especially if you’re not hosting production email for a company and you’re not leaving the server as an open relay, it isn’t very painful at all.

    You could also be less condescending, but as you said: your call. :)


  • Personal preference: Jellyfin instead of plex

    Some that I run that you don’t seem to have anything for:

    • Lancache (if you have several gaming PCs on the network or host any kind of lan party)
    • surveillance camera software e.g. shinobi
    • I see grafana, but other monitoring services like icinga, librenms, etc
    • Mayan EDMS - I’ve found this really helpful as anything I get in the mail, I scan in, and this makes it all searchable and retrievable.
    • There’s a whole hole you could dig if you start getting into home automation (I use home assistant)
