@0xAX There are a lot of this interesting tricks in the stl, but sometimes you find also a lot of small unsafe blocks lying around... a good one is the BTreeMap to stay in the dsa space or the Pin to go towards concurrency

@rvcas the compiler is the cheapest reviewer you can get...I'd keep it....way fewer tokens wasted on segfaults

[Matteo Marras @MattMarras]

@James_M_South Ugliness is a funny property for a programming language... it is blazingly fast though ... think again about it

[Matteo Marras @MattMarras]

@izadoesdev If we all move to Rust we can't rewrite anything in Rust anymore...not funny

[Matteo Marras @MattMarras]

@agnostoxxx Let people talk about it...the guy is Anthropic first employee and hater at the same time...and surprisingly it works!

[Matteo Marras @MattMarras]

@jacobtechtavern 10GB of xcode, installed for the build tools, and never opened...I don't even know how the UI looks like

[Matteo Marras @MattMarras]

@eliana_jordan Sometimes you just tackle problems you find in your everyday life which are not really marketable...so yeah just fun..

@theo it's not that announcing is hard, people are just scared of being noted i guess, i'm in that group too

[Matteo Marras @MattMarras]

@craigweiss The vibe check was always part of the interview, long before anyone vibecoded anything...before it was cool

[Matteo Marras @MattMarras]

@craigweiss Partially true, but there's still space for humans there, AI loops will drift the project into a never ending spiral of changes and improv...it is important to define where to stop

[Matteo Marras @MattMarras]

@anah_sahh Oh my goodness...you unlocked a new fear

[Matteo Marras @MattMarras]

@Corporate_CJP Tasks need less managing now, and agents give feedback and sort of guidance too (especially to juniors). Does the manager role shrink, or does "leading people" matter more?

[Matteo Marras @MattMarras]

@AlexTamkin Tools have always shaped judgment...maps, spreadsheets, GPS. The new failure mode is you still sign the report while the agent quietly picked the metric. Sourcing the agent verbatim is the new copy paste from Wikipedia in junior high

@Icebergy A truck is a safe deposit right now...ngl

[Matteo Marras @MattMarras]

@crescentforeal Looking a bit better, those giant nested for loops scare me even more than the bug...

[Matteo Marras @MattMarras]

@crescentforeal Definitely not AI slop this time

[Matteo Marras @MattMarras]

@mika_systems The only fix that holds is the agent's environment never holding anything worth stealing. That's why my agents run without ever seeing the real keys

[Matteo Marras @MattMarras]

@orhundev @ratatui_rs ratatui is just the go to for serious-terminal-tools nowadays. The theme switcher is also sick, good job.

@north0fnorth I live 15min walking distance to Central Park and I rarely go...I am so bad

@kentcdodds Grok Bot handing coding tasks to Cursor cloud agents, without opening Cursor. Close enough?
