“How I use Kate Editor”
I love the Kate Text editor. I use it for pretty much all the programming projects I do. Kate has been around for long time now, about 20 years!

Copilot taking over?

Of course, it can also do code completions and write complete code, if you want it to do so. ⌘ Read more

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. 🤷
