  • How much experience do you have with networking, exactly?

    The DNS record points to a private IPv4 address (10.0.0.41), which cannot be accessed from the internet for multiple reasons; first of which is that it’s almost certainly behind a NAT gateway.

    Your internet provider has given you a single publicly routable IPv4 address and assigned it to the WAN interface on your modem or router. If you want to access a host on the LAN, you’ll first have to configure port mapping or port forwarding on the router. Then you’ll have to open holes in your firewall and accept the fact that every bad actor will try to break into that host unless you know how to set up network security.


  • Better out-of-the-box hardware support, in my experience. We have a machine learning server at work, it didn’t see the GPUs on Debian Bullseye with the driver versions specified by the manufacturer, but worked perfectly with Ubuntu Server out of the box.

    A distribution that is preconfigured by professionals has great value in a practical setting, even if that value has diminished in the eyes of the kind of person that Lemmy attracts. If I had tried to get Debian working by overruling the manufacturer’s instructions, I’d have to take responsibility for it, both its maintenance and the downtime and potential damage if I had fucked something up. With Ubuntu, I get to delegate at least part of the responsibility to Canonical (while covering my own ass), and that’s something you can’t backport.



  • Linux has two different kinds of “used” memory. One is memory allocated for/by running processes that cannot be reclaimed or reallocated to another process. This memory is unavailable. The other kind is memory used for caching (ZFS, write-back cache, etc) that can be reclaimed and allocated for other things as needed. Memory that is not allocated in any way is free. Memory that is either free or allocated to cache is available.

    It looks like htop only shows unavailable memory as “used”, while proxmox shows the sum of unavailable and cached memory. Proxmox “uses” 11 GB, but it’s not running out of memory because most of it is “available”.




  • As a university sysadmin that spent half a fucking hour yesterday trying to log someone out of a classroom computer’s MS Office software (the “sign out” button did fuck all, go figure): fuck Microsoft, fuck Office, fuck Outlook, fuck Onedrive, fuck their SSO, and their mother too. Next semester I’m sanitizing the computers. Students will use LibreOffice and they’ll like it.

    I might be a little angry.
