Just to be that guy, 'use strict'; is specifically for JavaScript, and should still probably be used. With xHTML there were a few different DTDs that went in the DOCTYPE, Strict being one of them.

Some websites like Facebook and Google work, but other websites like Lemmy (any instance), Reddit, my CMMS, various wholesaler sites hosted both in AU and worldwide, are affected.

I wonder if IPv4 is somehow wonky, but IPv6 is working fine? Since Facebook and Google definitely support IPv6, the others may not (although Reddit should too).

You could try comparing ping -4 and ping -6 when it happens. That is if your network supports IPv6.

If you do get any inconsistencies with ping, you could also try experimenting with traceroute/tracert, to see where the delay happens.

Don't Python scripts need python at the beginning of the command that summons them?

Not if the script has a python shebang (e.g. #!/usr/bin/env python3), then it will run like any other script.

Pretty sure they're talking about why the meme says, 'WINDOWS', 'LINUX', and 'ios'.

It's worse with AppImages since they bundle everything in the same file. At least flatpaks do a little bit of deduplication with their platform packages.

Fun fact: IP version 5 is actually reserved for the Internet Streaming Protocol.

Uhh, this might be true for WebRTC, except not much uses WebRTC other than for realtime streaming/calling. Jellyfin for example is just an mp4 stream over http; and http(s) will only use the IP in the DNS record. I'd like to see a packet capture if you are certain something is switching IP.

I’m pretty sure QWERTY telegraph keyboards post-date typewriters.

Yeah they do! Actually a Japanese research paper (and this video) also theorises that they also grouped similar sounding letters in American Morse Code together (e.g. Z ∙ ∙ ∙  ∙ & SE ∙ ∙ ∙   ∙, or C ∙ ∙  ∙ & S ∙ ∙ ∙)

No worries! I believe there is a way to install desktop extensions on Android Firefox, but I'm not sure if it'll work.

You could try Privacy Pass.

Yeah, YunoHost explains why http://localhost:8536/ wouldn't be working. If cloudflared and Lemmy are in separate containers you have to put an actual IP in, since localhost points to the container itself.

How are you accessing it without Cloudflare? How do you know that Lemmy is actually listening?
