  • I’m a little confused – debt and balance aren’t the same thing, at least that’s my understanding?

    My understanding (and quick searches seem to agree?) is that cc balance is how much you owe on your card; cc debt is how much you carry over to your next statement. You only pay interest on the debt part.

    My cc balance climbs every month and then goes to zero when I pay it off, so I don’t pay any interest.




  • nc is useful. For example: if you have a disk image downloaded on computer A but want to write it to an SD card on computer B, you can run something like

    user@B: nc -l 1234 | pv > /dev/$sdcard

    And

    user@A: nc B.local 1234 < /path/to/image.img

    (I may have syntax messed up–also don’t transfer sensitive information this way!)

    Similarly, no need to store a compressed file if you’re going to uncompress it as soon as you download it—just pipe wget or curl to tar or xz or whatever.

    I once burnt a CD of a Linux ISO by wgeting directly to cdrecord. It was actually kinda useful because it was on a laptop that was running out of HD space. Luckily the University Internet was fast and the CD was successfully burnt :)



  • Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

    My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

    It’s a fun exercise, not sure I implemented it in a smart way, but it works :)
