Hot take: C++ Twitter seems caught up in a weird memory safety āskills issueā debate this week, but letās not forget what makes Rust truly shine. Itās not just about memory safety; itās about fearless refactoring enabled by the stellar type system. #Rustlang š¦

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, āseems legitā,notāhow ridiculousā š @TheWarOnCars (also note car still parked in bike lane š¤¦āāļø)

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

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

Iām 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 itās SO LOUD!!

For decades, the guidance given to software engineers has been to check the memory allocation results. This validation step is necessary to avoid crashes. However, in user mode, in modern...

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

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

āThe reason he couldnāt 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.
