@alex_02 yeah i have absolutely zero disrespect for infosec researchers but sometimes it has unfortunately gone other way around. it is always best to respect any possible work that you have no experience, starting from selling burgers at mcdonalds 🙂 otherwise, in the end, you are just making fool of yourself.

having worked with many #infosec #researcher's over the years sometimes (definitely not always) they have a misconception that being able to build and/or detonate a bomb gives you capability to be a great #programmer.

if this was the case, safe thieves should build safes, and police department should be recruited from organized crime groups.

an infosec researcher can also definitely be a great programmer but they are different crafts.

"Toinen yllätys oli se, että poliisi sai avattua vahvasti salattujen palvelimien tiedot auki. Niitä suojannut salasana oli 64-merkkinen, ja sen poliisi onnistui selvittämään."

Tämä jäi itselläkin kytemään, että millä tempulla salasana saatiin selville.

En käytä ruokalähettipalveluja, koska bisnesmalli on moraaliton. Omistajien verojen maksu on taas tämän tosiasian valkopesua.Toisten selkänahasta revitty fyffe on väärin, vaikka siitä maksaisi kuinka paljon veroja.

@dpom @neovim A quote from Helix home page: "By starting from scratch we were able to learn from our experience with Vim and make some breaking changes."

This is totally incorrect. It is a different beast. Is Eclipse vim "with some breaking changes"?

Sorry, now I think I've flushed all this out of my system :-) Apologies...

@dpom @neovim And people doing their "new" and "better" thing tend to get bored fast too: https://github.com/ogham/exa/issues/1243. I mean vim and neovim have decades of time span. E.g. the first Amiga version of Vim was implemented in 1988 being older project than even Linux kernel. Many of the maintainers of the new better things were not even born yet.

@dpom @neovim Also I hate when people claim a language being "memory safe". No human creation is. It is for sure a language with strong memory safety properties. I like brutal honesty more than being sexy.

@dpom @neovim Yeah, it is like Haskell community but with volume :-) Try to pointing out a real issue in Rust and you feel like that you are speaking with someone from the Church of Scientology. I still like and use the language but I fully receive and understand your comment.

One thing where I would use #rustlang rewrite: vim/neovim clone. Helix/Amp etc. have the problem that they try to do something new.

Actually the best would be if @neovim would join the club of Firefox, Linux etc. and provide shenanigans for rewriting parts of it in Rust. I promise to contribute in this effort, if that ever happens (no time for working on the shenanigans unfortunately).

OK, a bit more intensive to get the spacing right (or readable):

>>> ' '.join(list(map(lambda x: x[::-1], list(map(lambda i: val[::-1][i:i + 4], range(0, len(val), 4)))[::-1])))
'1 0001 0001 1001 1110'

printing hex in the #python shell:

>>> val = bin(0x1119e)[2:]
>>> ' '.join(list(map(lambda i: val[i:i + 4], range(0, len(val), 4))))
'1000 1000 1100 1111 0'
