  • What was the strangest reason you got in trouble in school?

    Jump

  • (High school, approx 1 year ago) Not particularly trouble, just a bit of scolding from school IT admin.

    The school network blocked certain sites and services. I also wanted to convert a few videos to AV1, but I had a shit laptop, and the school PCs were pretty fine.

    So, in steps:

    1. One of the teachers with admin rights created accounts for us on the most powerful PCs with RDP access to use them from other, shitty PCs.
    2. I wanted to extend this access, and in the end went with AnyDesk since that didn't need admin rights, but could still do port forwarding. This was important as AnyDesk could run in background, but wouldn't show anything without being logged in. But I could port forward to the computer's RDP and connect to that.
    3. There was VirtualBox. Cool. I installed Arch for the video conversions, and Ubuntu server for playing around.
    4. I've experimented with remote access via ssh-j.com (SSH jump server), but didn't particularly like that. I wish I had known about Tailscale at the time. I only used AnyDesk for port-forwarding to the VM SSH.
    5. I've installed tinyproxy (simple HTTP proxy server) and OpenVPN (later switched to Wireguard) onto the Ubuntu server VM. I've set it up as a proxy server that would connect to a VPN (ProtonVPN, later Mullvad) and share that connection over the HTTP proxy on LAN.
    6. I've distributed the proxy server details and instructions on how to set up a computer to use it to other students. They confirmed it bypassed blocking, and even online games worked fine over it.
    7. The school IT admin came into the class with that computer (when I was there which was a coincidence), and asked who was using Wireguard. Then he told me he'd block it by the end of the day, and to finish whatever I was doing.
    8. Specifically Wireguard didn't work on any ports, so I assume it was DPI based blocking. However, there was an exception, port 123 used for NTP. Proxy back in service over 123.
    9. Later on he was quite clear that I am not allowed to use the school computers for personal stuff like video processing, that I very much shouldn't be helping others evade the blocking because it exists for a reason, and then got a bit mad when I also mentioned the remote access, because yeah, a bit of security hole.

    I personally wouldn't trust AnyDesk for access to my network, but that was all I had. I use Tailscale now.

    Welp, next year they upgraded the setup, and now computers don't have local accounts anymore and use some login via e-mail. But I also just finished HS, so not my problem anymore.

  • More battery drain with anti-skip.The tables have turned later on. The anti-skip would extend battery life. It would get enough buffer allowing the CD to spin-down and then it would spin back up when needed. This time could be even longer if playing MP3.

    For example, my Panasonic SL-CT520 does 100 second "anti-skip" (at this point it's not really just anti-skip), and with MP3 cites up to 155h of playback time. Unfortunately, the unit I have can't play CD-RW (it is mentioned in the manual) which probably means a degraded laser.

    But even with CDDA, my Sony D-EJ000 cites 16 hours with anti-skip and only 11 hours without anti-skip. Unfortunately, in this case the anti-skip also reduces audio quality slightly since it uses lossy compression, so I keep it off.At least I think that's what the manual is trying to say

    To enjoy high quality CD sound, select “G-off”.

  • Let me think, when did I last use a CD player like that?

    Oh, I remember. Today morning. Oh, it's been a while.

  • Perhaps a problem in museum, but at least where I live any highly portable CD player like this gets called "discman" same as with portable cassette players being called "walkman".

  • Communities don't automatically federate to other instances. Someone has to search for them specifically like !ComicStrips@hilariouschaos.com and subscribe to it.

    If I open your URL without being logged in, that info is there

    You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !ComicStrips@hilariouschaos.com

    And now once I did that, it exists: https://lemmy.sdf.org/c/ComicStrips@hilariouschaos.comThough it won't update as I haven't subscribed to it, and I assume no one else did (from SDF) in these few seconds yet.

  • In my opinion the last great was Android 7. Just getting more locked down since.

    But also it was kinda funny when manufacturers left over some of their software. I think it was ZTE which had a hidden menu to change the fucking IMEI.

  • Unless it's quite shitty.

    I've got Ulefone, and the default audio source (software) is dogshit quality. And that's what the camera app uses, unless I use something like Open Camera where I can manually select "Unprocessed" rather than default.
