SBB C 5/6 "Elefant”

#trains #steamtrain #train #photography

(since @elaterite@mastoart.social posted the Big Boy, I thought I'd post a freight locomotive from Switzerland; I stood on its footplate in Brugg last year and I'm looking forward to do it again this year)

Replying to @Viss@mastodon.social
@Viss@mastodon.social One thing I really dislike about the wording is that it implies that sanitisation of data inserted into prompts is possible. As far as I understand there is no reliable way to do that.

@bagder@mastodon.social The name that the attacker used is likely fake. Unfortunately it happens to be the name of a person I used to work with that was not related to this backdoor at all. I know that they got harassed online because of that coincidence. When possible, I think it's better to omit the name or include a note that it's likely fake.

@zzt@mas.to @aral@mastodon.ar.al @element@mastodon.matrix.org This was posted out of spite in case it wasn't obvious, I really wish something better than irc (maybe matrix, maybe something else) is the future. There clearly are usecases that Signal doesn't fulfill.
