@pingiun_ @TherumFollower In Swift:

let s = "🤷‍♂️"
s.count // 1
s.unicodeScalars.count // 4
s.utf16.count // 5
s.utf8.count // 13

[Greg Titus @gregtitus]

@pingiun_ @TherumFollower There are exceptions and complexities, but strings are natively Unicode and internally can be utf-8 or -16, can contain combining characters or emoji, etc. so individual characters can be different internal lengths, thus, counting them needs to walk over them.

@OldManKris I don't think it's possible to explain anything to someone who insists on asking the wrong questions.

[Greg Titus @gregtitus]

@optshiftk In my defense, it was _significantly_ faster in that case!

"bullet point summary of what your code commits have achieved in the past 6 months":

Well, probably most impactful, I made a one line change to optimize encryption key rollover scanning to only look at needed instead of all files... had it reviewed by a co-worker, of course...

@CoreSerena @stephentyrone @jckarter "And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Mathusael begat Metasyntactic Variable."

@hollyborla Thanks!

@myerscb @Opaopa13 @evacide @benjaminlowe Maybe start by going and looking in the dictionary under "I" for "implicit", that'll hopefully resolve a lot of the confusion.

@amcvittie What's really poetic is how your description isn't "shitty(?) poetry". Like, you're pretty certain it's shitty, it's just whether or not it's poetry that is unclear.

@CastIrony It's also possible that he used to be more exposed to the real world (i.e. less dumb) and in the last decade or so he's ended up in a billionaire bubble and just has no conception of the thought processes of the people who work for him any more.

@TeslaRoshi @peterclowes "Keep me, personally, Elon Musk, from losing money on my investment" is not a vision that anyone besides Elon (and apparently you) is actually going to be motivated to work hard for. This should be obvious.

[Greg Titus @gregtitus]

Immediately go looking for the "cleverest", most obscure one-liner that you somehow slipped by code review...

Elon Musk is also asking for up 10 screenshots of the "most salient lines of code" from Twitter engineers 2/

@optshiftk @amcvittie Ah, I see. It's a load-bearing shirt.

[Greg Titus @gregtitus]

@evandyer @alexeheath @lookner So he replaces them. And they learn how the code works from whom? And it takes how long? Software engineers are not perfectly replaceable cogs in a machine, they each have individual knowledge of the code base that no one else has.

[Greg Titus @gregtitus]

@myerscb @evacide @benjaminlowe Not funny, but same point: Imagine those 7500 are bloated layabouts. They each do 20% of the work they should. If you cut 80% of those people, you still lose 80% of the knowledge of how the place runs. Your 20% 'hardcore' COULD do all the work but only know how to do 20% of it.
