AntoinePrv @antoineprv.bsky.social · 27/02/2026Very nice post! I've long been thinking we should get models and datasets from package managers. On the conda side, I've been wanting to do a CEP or server to automatically package arbitrary artifacts while avoiding duplicating the storage. 010
Reposted by AntoinePrvAntoine Pitrou @pitrou.net · 26/02/2026At @quantstack.bsky.social we designed novel bit-unpacking SIMD optimizations for @arrow.apache.org and #ApacheParquet, and implemented them entirely using C++ metaprogramming instead of Python-based code generation. We'll publish a deep dive blog post soon. github.com/apache/arrow...github.comGH-48277: [C++][Parquet] unpack with shuffle algorithm by AntoinePrv · Pull Request #47994 · apache/arrowRationale for this change The current bit-unpacking algorithm (which is implemented as a C++ code generator script in Python) does not fully leverage SIMD operations: all loads and some bitshifts u... 1106

AntoinePrv @antoineprv.bsky.social · 02/12/2025SIMD coding is hard: platforms, inconsistencies, lane constraints... but xsimd abstracts a lot away. With my first contributions, I improved byte shuffling, now available in the latest 14.0 release. #C++ #SIMD #xsimd #openSource 062

AntoinePrv @antoineprv.bsky.social · 02/12/2024As for constraints, you can model all decision variables as binaries and express conjunctive normal form as linear constraints. In both cases (SAT and ILP), I think you'd need to make dedicated heuristics to have smth reasonable for package manager, so it boils down to the most adaptable codebase. 100
AntoinePrv @antoineprv.bsky.social · 02/12/2024What would be your optimization objective? Probably some heuristic of what it means to be "up to date" with open questions as "Is it better to have indirect dependency very outdated rather than a direct one slightly outdated", but you'd also need to defined "very" and "slightly". 100
