Hot take: C++ Twitter seems caught up in a weird memory safety ā€œskills issueā€ debate this week, but let’s not forget what makes Rust truly shine. It’s not just about memory safety; it’s about fearless refactoring enabled by the stellar type system. #Rustlang šŸ¦€

I love how whatever dot @Spottnik @seattledot @wsdot installed this temp bike lane decided it needs this much crash buffer. On a 20mph. Across from a stop sign. And my first thought, ā€œseems legitā€,notā€œhow ridiculousā€ šŸ˜† @TheWarOnCars (also note car still parked in bike lane šŸ¤¦ā€ā™‚ļø)

Neat! The 2016-2018 sections is all stuff I was closely involved in while working on fbios startup performance. I moved off of mobile in 2019 before the Swift stuff came online.

@_hiraditya_ and I will present our past work (developed with @jeffdthomas) about the challenges of tracking user mode memory allocations at https://t.co/Z52LrLbugq. Abstract: https://t.co/SMprpiTj4L Excited to talk to fellow engineers ;-) Cc: @Ayushi_Rastogi #LLVM #CGO #malloc

.@Atlas_Van_Lines your drivers are blocking a high traffic bike lane in Seattle. Please advise them that this is dangerous and inappropriate behavior.

I’m turning into someone I do not like. I have become a crazy person yelling at LOUD cars. Can anything be done about vehicles that have modified/removed mufflers (specifically: Aurora, Dexter, and Westlake near SLU)? @SeattlePD @seattledot @Spottnik @UrbanistOrg it’s SO LOUD!!

How anyone is surprised by the current Colorado River issues, I remember watching this film about it nearly *a decade ago*. Have we just done nothing in that time? Humans suck :(

Compiler internals are quite different from linker internals, but I found that Zig compiler's data-oriented design is very similar to what I was thinking when I was designing the mold linker. I enjoyed watching @andy_kelley's talk. https://t.co/ot4yGOZRA3

Not _entirely_ dissatisfied with #AdventOfCode day2.2 solution. Lessons: Would be cleaner w/o so much (over)use of `std::pair` and `std::variant`s (via `std::visit`) was still kinda difficult to work with in c++17 :/ #AdventOfCodeSpoilers https://t.co/TJ5LFJItao

Not sad about my day1 solution, but `inner_product` was the missed algorithm for me. @tristanbrindle with this beauty #AdventOfCode

...and then I realised you can write it using just the STL and I think it's actually quite beautiful #cplusplus

ā€œThe reason he couldn’t stop is because he was accelerating to blow more diesel fuel on these cyclists.ā€

Six cyclists were run over by a pickup truck along old 290, roughly 2 miles west of Waller.Ā  In total, four of the cyclists had to be taken to area hospitals, including 2 by helicopter.
