in these trying times, it's refreshing to see someone willing to speak the truth

@inthehands whenever I see someone post that guys posts I can only think about jwz’s anecdotes about him leaving the Netscape bathrooms uninhabitable every time he used them, and how thats what my timeline feels like after seeing his posts

@vitaut the most sensible default for binary floats is clearly hexadecimal float notation

@steve @cr1901 @pkhuong and even with that, compilers will often sever the dependency explicitly by doing an xor or movsx/xx to the destination at the start of an operation chain

the other thing that makes 16 bit operations slow on some uarches iirc is a penalty for the operand size prefix byte

@steve @cr1901 @pkhuong nonetheless it is absolutely the right thing for a contemporary ISA to not have unnecessary partial register updates in the first place, to cr1901’s point about risc-v. luckily AMD at least figured that out by the time they designed x86-64

so anyway, I enrolled, and before i knew it, two years had passed. and that's how i got my dissociate's degree

¡buenos días! es un otro “martes martes martes” martes

@mcc French is such an elegant language

It’s not just you—there *are* more disturbances in the Force lately. It’s called ensithification

incredible. blues singers knew about vi a full two decades before the first Unix distribution

@emily it's longstanding intel tradition. the 8085 had the 8-bit registers A, B, C, D; the 8086 made them 16-bit AX "A extended" etc.; then the 80386 made them 32-bit EAX "extended A extended"

learn to type English like a programmer!

"first" -> 0st
"second" -> 1nd
"third" -> 2rd

I gotta say, I really appreciate the “juice” the Safari team put into the “delete annoying elements” feature

@mcc if you're fortran-curious and objective-c is too much C for you, i have good news

@helge @mcc maybe there's a happier timeline where the object-oriented hype phase was just people adding Smalltalk on top of every language, instead of whatever C++ and Java is

We're excited to announce NAPL, a special-purpose tool that is emphatically *not* a general purpose programming language! *5 seconds later* We regret to inform you that NAPL is accidentally Turing-complete

instead of using file extensions and having the OS map those to file icons, why don't we just put all the file icons in Unicode and start filenames with an emoji to indicate the file type

number system with +0, –0, and 0⁰

@helge @mattiem @calicoding on Apple Silicon™️, the expensiveness is at least only if you have actual contention accessing the refcount

@helge @mattiem @calicoding the particular instructions used for refcounting get speculatively executed as if they were nonatomic, so in the case where there's no contention, there's very little overhead (because the atomic codegen still needs more instructions than a nonatomic update, etc.) if it turns out later the memory location was contended then you throw all that work away and do it properly
