I moved to Bluesky: bsky.app/profile/sunitr… This is my last post on what was formerly known as Twitter.

Das war‘s für mich mit Twitter. Nach knapp 16 Jahren wird dieser Account stillgelegt. Sie finden mich ab sofort auf Bluesky: bsky.app/profile/arminw… - und natürlich auf meinem Blog. Dort erkläre ich auch warum: arminwolf.at/2024/11/17/twi… Danke für viele super Jahre hier! #eXit

Wir müssen Neues wagen. Die Herausforderungen sind neu. Die Lösungen sind nicht einfach. Aber sie sind möglich. Wenn wir alte Rezepte loslassen und neu denken:

@_plop_ Also note, when you have keys that are fast to compare (e.g. a uint64_t), the fingerprint is still helpful because it safes us from needing to do memory loads from random locations and just keep comparing bytes from the 8 bytes overhead thats sequentially load into memory

@_plop_ So in the 8 bytes of overhead 4 bytes index (up to 4.2 billion map size), 3 bytes offset (up to 16 mill. keys map to one bucket), and 1 byte fingerprint (1/256 = 0.4% of incorrect key comparisons) seems the most reasonable tradeoff.

Hey @sunitram I'm looking at the details of unordered_dense and I have a question: why use only 1 byte of hash fingerprint? Using 2 bytes doesn't help meaningfully? (2 bytes for the distance would be enough, no?)

@tsoding @FallenOne58035 And then your want proper allocator support, correct handling of member moving in case it's not noexcept, ...

@FallenOne58035 Dynamic Arrays (which is what std::vector is, calling it a vector is the dumbest idea in the history of computing) is such a trivial Data Structure you can implement it literally in 2 minutes x.com/tsoding/status…

As a person who programs in Rust since 2016 I can tell you that Rust is a very safe, unergonomic language with annoying community and atrocious syntax. Which is somehow surprisingly miles better than modern C++.

This is how you update all your models in #ollama ollama list | tail -n +2 | awk '{print $1}' | xargs -t -n1 ollama pull

@Eva_Kimani_ I've been to Lake Como, it's a 1-day car trip from where I live. Much less tourist-y than Lake Garda. It's nice to hike there, but it was very windy at the lake. Excellent food though 👌

@realDonaldTrump Why is he always so weird

Elon Musk’s daughter is savage😂

The CrowdStrike regex desaster could have been easily found with a fuzzer.
