Signing key change for Kali Linux

This is not only you, this is for everyone, and this is entirely

repository (you might have noticed that there was no update since

The return of the tilde
As some of you may have noticed my web page is now under /~mc instead
of just /mc. This is a return to olden times.
The Apache web server, and probably many other web servers, had a
simple way of adding personal web pages for local users. This meant
that an URL ending with ~mc led directly to a subdirectory of user
mc’s home directory. Whatever they put in that directory was
immediately available on the Intertubes! Neat, huh?

Regex Isn’t Hard - Tim Kellogg 👈 this is a pretty good conscience article on regexes, and I agree, regex isn’t that hard™ – However I think I can make the TL;DR even shorter 😅
Regex core subset (portable across languages):
Character sets
• a matches “a”
• [a-z] any lowercase
• [a-zA-Z0-9] alphanumeric
• [^ab] any char but a or b
Repetition (applies to the preceding atom)
• ? zero or one
• * zero or more
• + one or more
Groups
• (ab)+ matches “ab”, “abab”, …
• Capture for extract/substitute via $1 or \1
Operators
• foo|bar = foo or bar
• ^ start anchor
• $ end anchor
Ignore non‑portable shortcuts: \w, ., {n}, *?, lookarounds.

@prologic@twtxt.net Since you have to check and double check everything it spits out (without providing sources), I don’t find any of this helpful. It’s like someone’s in the room with you and that person is saying random stuff that might or might not be correct. At best, it might spark some new idea in your head and then you follow that idea the traditional way.
Information published on the internet (or anywhere, for that matter) was never guaranteed to be correct. But at least you had a “frame of reference”: “Ah, I read this information about Linux on a blog that usually posts about Windows, so this one single Linux post might not necessarily be correct.” That is completely lost with LLMs. It’s literally all mushed together. 🤷
