  • 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 :)
















  • This is actually the one that I would agree with (edit: see below), if the difference is “professional” vs. “academic.” I certainly wouldn’t call a natural science degree professional, and if you’re in a research institution studying some form of engineering I’d probably put you in the same category. Just my experience/opinion though (and the rest of the exclusions are super stupid, I agree).

    Edit: from the replies, this is referring to Professional Engineering; in my corner of the world, “Engineer” is an overloaded term that generally means electrical, mechanical, software, and sometimes computer engineer. My comment was referring to these engineers, who are rarely licensed and study alongside scientists in school. I completely agree with parent in the context of “professional engineering” (I mean…it’s right there in the name…).
