  Can’t even ignore the pain of getting a post deleted…

  But delete-instead-of-downvote is how you drive out the trolls. If you give shitty people a platform labeled “I think this person is wrong” then you’ve still given them a platform.

  They said “please stop donating”. Returning funds or organizing what to do with them is a bunch of work. If they’re shutting down because running the instance is too much work and they feel hassled then I wouldn’t begrudge them just keeping the few thousand left over.

  The title of this post is disappointing. The given answer is sound and it seems safe to assume it was arrived at by thinking mathematically.

  Just saw: they’re changing it back because you don’t appreciate it enough :(

• ⁨Comment⁩ on ⁨Your help needed: PhD research on why people choose to self-host⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Thanks for linking that. Reading the paper, it looks like the majority of the “self-host” population they’re capturing is people who have a WordPress site. By my reading, the wording of the paper would disqualify a wordpress.com-hosted site as “self-hosted”. But I’d be very suspicious of their methodology and would expect that quite a few people who use WP-hosted reported as self-hosted because the language is pretty confusing.

• ⁨Comment⁩ on ⁨Rhubarb⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Some people think, “oh this witch leaving a note means she’s really powerless and I can keep taking the rhubarb.” It’s not going to be so awesome when she forecloses on his first-born.

  I was at Google when they announced that only AI-related projects would be able to request increased budget. I don’t know if they’re still doing that specifically, but I’m sure they are still massively incentivizing teams to slap an “AI Inside” sticker on everything.

• ⁨Comment⁩ on ⁨Can I self host a VPN that sneakies through the China firewall?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  To someone watching network traffic, a VPN connection looks like two machines exchanging encrypted packets. You can’t see the actual data inside the packet, but you can see all the metadata (who it’s addressed to, how big it is, whether its TCP or UDP, when it’s sent). From the metadata, you can make guesses about the content and VPN would be pretty easy to guess.

  When sending a packet over the Internet, there’s two parts of the address: the IP address and the port. The IP address is a specific Internet location, blocks of IP addresses are owned by groups (who owns what is public info) and there are many services that do geo-ip mappings. So if you’re connecting to an IP address that belongs to a known VPN provider, that’s easy.

  The second part of the address is the port-number. Servers choose port-numbers to listen to and the common convention is to use well-known ports. So, for example, HTTPS traffic is on port 443. If you see a computer making a lot of requests to port 443, even though the traffic is encrypted we can guess that they’re browsing the web. Wikipedia has a list (which is incomplete because new software can be written at any time and make up a new port that it prefers) and you can see lots of VPN software on there. If you’re connecting to a port that’s known to be used by VPN software, we can guess that you’re using VPN software.

  Once you’re running VPN software on an unknown machine and have configured it to use a non-standard port, it’s a bit harder to tell what’s happening, but it’s still possible to make a pretty confident guess. Some VPN setups use “split-tunnel” where some traffic goes over VPN and some over the public Internet. (This is most common in corporate use where private company traffic goes in the tunnel, but browsing Lemmy would go over public.) Sometimes, DNS doesn’t go through the VPN which is a big give-away: you looked up “foo.com” and sent traffic to 172.67.137.159. Then you looked up “bar.org” and sent traffic to the same 172.67.137.159. Odds are that thing is a VPN (or other proxy).

  Finally, you can just look at more complex patterns in the traffic. If you’re interested, you could install Wireshark or just run tcpdump and watch your own network traffic. Basic web-browsing is very visible: you send a small request (“HTTP GET /index.html”) and you get a much bigger response back. Then you send a flurry of smaller requests for all the page elements and get a bunch of bigger responses. Then there’s a huuuuge pause. Different protocols will have different shapes (a MOBA game would probably show more even traffic back-and-forth).

  You wouldn’t be able to be absolutely confident with this, but over enough time and people you can get very close. Or you can just be a bit aggressive and incorrectly mark things as VPNs.
