    So just going off of what I am somewhat familiar with - there’s a thing with certain wifi frequencies where at times that band needs to be used for military radar, satellite, and other radar. This seems to be sometimes a result of opening up frequencies that were already being used, with the stipulation that the new devices should stop using the frequency and give way to the original use.

    The way it works in wifi, is that any device using DFS channels has some form of radar detection, so it automatically changes wifi channels as soon as it detects it. It sounds like in order to make sure they comply as perfectly as possible, the radar detection leans towards being overly sensitive.

    (I double checked my facts with this technical write-up on dfs and radar if you want further reading: https://www.cwnp.com/dynamic-frequency-selection/ )

    So I would wager that it’s not necessary the power of the radar taking out the drones, but the drones detecting the presence of radar and choosing to shut down based on regulatory requirements.

    You could probably transmit a very weak radar signal and trigger / interfere with a lot of devices due to their sensitivity - but yeah that would be super illegal, and plenty of hobbyist ham radio operators with radio direction finding equipment would be eager to track you down. I used to live in an area close to radar so while my home wifi only had to switch channels once a month, making it very worth it to be the only person on those channels 99% of the time, my workplace had DFS events daily so they had to avoid those channels.

    Also why the fuck does the boat painted on the fence extend into reality above the fence???

    Edit: could be that they have 2 boats and lined up the painting perfectly, but this user has posted several images in the last month that smell of AI so I’m not inclined to give the benefit of the doubt.

    My parents simply didn’t buy any games beyond roller coaster tycoon 2, myst 3 exile, and MS combat flight sim WW2. So it didn’t really matter what the content was in any other games because that was it.

    I ended up pirating whatever I wanted and my parents didn’t seem to care, I think it was more about being opposed to spending money on games. We didn’t have any consoles whatsoever.

    My homelab has been mostly on autopilot for a while. Synology 6 bay running most lighter weight docker stuff (arrstack, immich, etc) and an Intel nuc running heavy stuff (quicksync transcodes for Plex+jf, ollama). Both connected to digitalocean via WG for reverse proxy due to CGNAT.

    I had my router SSD either die or get corrupted this past week, haven’t looked much at the old SSD besides trying to extract the config off of it. I ended up just fresh installing opnsense because I didnt have any recent backups (my Synology and nuc back up to rsync.net, but I haven’t gotten around to automated backups for my router since it’s basically a plain config, and my cloud reverse proxy which is just a basic docker compose + small haproxy config). Luckily my homelab reaching out to the cloud reverse proxy means there’s basically no important config on my router anymore, they just need DHCP and a connection.

    Besides that the arrstack just chugs along on its own.

    I recently figured out I can load jellyfin playback URLs into vrchat video players, either direct stream or through the transcoding pipeline as an m3u8 that live transcodes based on the url parameters you set. This is great because the way watch parties in VRChat works is that everyone in an instance loads the same URL pasted into media players and syncs the playback. That means you need to have a publicly accessible url (preferably with a token of some sort) that can be loaded by an arbitrary number of unique IP addresses simultaneously, which I don’t think is doable with Plex.

    I’m now working on a little web app to let me log into Jellyfin, search/browse media, and generate the links with arbitrary or pre-set transcode settings for easy copy/pasting into VRChat. The reason it’s needed is that Jellyfin only provides the original file without transcoding when you use the “copy stream” option, so I believe the only way to get a transcoded stream url currently is to set the web interface to specific settings and grab the URL from the network. But that doesn’t let you set arbitrary stuff like codecs and subtitle burn in and overriding what it thinks you support. So a simple app to construct the URL will make VRChat watch parties a lot easier.
