Hot take: C++ Twitter seems caught up in a weird memory safety “skills issue” 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 🦀


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, “seems legit”,not“how ridiculous” 😆 @TheWarOnCars (also note car still parked in bike lane 🤦‍♂️)

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 llvm.org/devmtg/2023-02…. Abstract: bit.ly/3xiq9Am Excited to talk to fellow engineers ;-) Cc: @Ayushi_Rastogi #LLVM #CGO #malloc

Our short paper "Who Ate My Memory? Towards Attribution in Memory Management" was accepted at the SEIP track of @ICSEconf! We tackled this problem at @Microsoft and @Meta. Preprint: bit.ly/3hOz887 @Ayushi_Rastogi, @jeffdthomas, @NachiNagappan #ICSE2023 #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!!

Our contrarian full paper "When malloc() Never Returns NULL --- Reliability as an Illusion" got accepted at the Industry Track of @ISSREConf. Preprint: arxiv.org/abs/2208.08484 With @_hiraditya_, @Ayushi_Rastogi, @jeffdthomas, and @NachiNagappan. #ISSRE #malloc


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 :( vimeo.com/114386144

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. vimeo.com/649009599#t=30…

Our paper "Quantifying Daily Evolution of Mobile Software Based on Memory Allocator Churn" was accepted at MOBILESoft '22 NIER track. Excellent coauthors: @jeffdthomas, @_hiraditya_, @NachiNagappan, and @Ayushi_Rastogi. Preprint soon. #mobilesoft #nomalloc


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
