It's fine to ask the hotel if they have wired Ethernet in rooms before you book, some do.

Typically wifi, even in the best hotels, can get pretty terrible at peak times.

Great primer. You might consider having a thoughtful moderation bot/account when enforcing moderation decisions for the community that don't reflect admin decisions for instance rules as a whole.

I've looked at the voting patterns and I can't establish the link you mentioned, the falsewhite accounts are obviously alts/sockpuppets of each other, that is all I can say

43 downvotes across 2 minutes but at a 4 hours earlier then the other downvoting falsewhite accounts.

Looks like a normal short term lemmy fight, someone didn't like what they said in a thread and opened their history and downvoted everything on the first screen. Going back 3 days and the downvotes stop.

https://lemvotes.org/user/falsewhite@lemmy.dbzer0.com 17 downvotes in 2 minutes all against shalafi 6:41-6:42
https://lemvotes.org/user/falsewhite@programming.dev 79 downvotes in 2 minutes all against shalafi 6:38-6:40
https://lemvotes.org/user/falsewhite@lemmy.world 87 downvotes in 3 minutes all against shalafi 6:25-6:27, and 6:44-6:45

lemmy.world appears to be their main account, this seems to be the post that triggered them do do their downvoting spree: https://lemmy.world/post/41260627

Looks like the sock puppet master was angry for about 20 minutes, and got tired of manually downvoting. Still pretty terrible vote manipulation making lemmy a hostile place.

not posting this to !ketogenic@discuss.online because the topic isn't just about a ketogenic metabolism, but the impact of ketones both exogenous and endogenous... and mostly i dont want to annoy people with a cross post filling up the feed

The statement around ~13 where ketones have a protective effect on cancer outside of just not being sugar is VERY interesting and ill have to dig into the Huang paper

Oh, I don't need this to help children! I need this so I don't forget the moves myself, and to get other adults to enjoy a game or two.

Having a 30 something learn 15 something symbols to play a game or two to see what it is like is a big ask.

https://en.wikipedia.org/wiki/List_of_chess_variants

There are many different types of chess out there, and as a game tourist I want to make things easy on myself. Chu Shogi has 21 different symbols for example, it's going to take a minute to memorize that, and good luck convincing someone else to memorize it to play a few games.

example:

lishogi is kinda new (5ish years I think), i was around when it got forked from lichess.

I use lishogi because you don't need an account and it just works, but I think its pretty niche. It does have a adapted stockfish engine to play against.

Inside japan I think shogiwars is the most popular, but its kinda impenetrable for me, so I just tried it now... they have english in 2026 which is nice! But you can't change the pieces, however its a real experience worth visiting once.

Have you seen Chu Shogi? https://en.wikipedia.org/wiki/Chu_shogi - It's a whole thing, intense, its on lishogi but without a ai bot to play against, so human vs human only. It would be nice to play chu shogi against a bot to practice, but I don't know where to do that.
