Dirty Frag - kolejna metoda na root’a pod Linuxem

Pamiętacie Dirty Pipe? Łataliście ostatnio  Copy Fail? Pasy zapięte? Nie? To niedobrze, bo kilka godzin temu pojawiła się nowa podatność określona mianem Dirty Frag. W ramce poniżej znajduje się tymczasowe rozwiązanie mające na celu wyłączenie niebezpiecznych modułów. Jest to luka klasy LPE (local privilege escalation), która pozwala na podniesienie uprawnień...

Ah, yes, another #Rustacean waxing poetic about "lifetimes" as if they were the next Beatles. 🎸🎻 Spoiler: Zero-copy isn’t going to revolutionize your code unless you’re a database server in disguise. 🤔💾

Zero-copy Protobuf and ConnectRPC for Rust

As part of my work at Anthropic, I open sourced two Rust crates that fill a gap in the RPC ecosystem: buffa, a pure-Rust Protocol Buffers…

Ah yes, the groundbreaking revelation that tech bros have finally figured out how to make their shiny new #Apple toys run AI without having the audacity to actually move data around. 🤯 Meanwhile, the real winners are the rest of us, who have discovered that we can achieve the same feat by *not* buying into every overhyped "ZeroCopy" buzzword. 🍏💻

Zero-Copy GPU Inference from WebAssembly on Apple Silicon

A WebAssembly module's linear memory can be shared directly with the Apple Silicon GPU: no copies, no serialization, no intermediate buffers. Here's how the zero-copy chain works, what we measured, and what it enables for stateful AI inference.

New blog post: "The inner workings of TCP zero-copy"

Did some investigation into how exactly TCP zero-copy works under the hood, and figured I'd share my findings in a (more or less) digestible format.

Kafka sử dụng bộ nhớ cache hệ thống (OS page buffer) thay vì caching tại ứng dụng, giảm thiểu ghi nhớ rác (GC) và giữ cache sau khởi động. Ngoài ra, Kafka áp dụng "Zero Copy" bằng Linux's sendfile API để giảm 2 lần sao chép dữ liệu khi truyền socket. #Kafka #Performance #Optimization #OSCache #ZeroCopy #HiệuSuất #TốiƯuHóa #CacheHệThống
