Using Antigravity for Statistical Physics in JavaScript

I like learning about the hidden benchmarks that everyone seems to bring out when a new large language model drops. Mine used to be asking the model about obscure but well-documented people on the internet like family members or acquaintances in the sciences or with IMDB credits. Since ~late 2024, most models are nailing that one so it’s not as interesting. Instead, I’ve moved onto ...

Building the largest known Kubernetes cluster

https://storage.googleapis.com/gweb-cloudblog-publish/images/1_Phase_1__Establishing_a_performance_base.max-1300x1300.png
Google Cloud's Google Kubernetes Engine (GKE) has successfully scaled to 130,000 nodes, twice the officially supported limit, and sustained Pod throughput of 1,000 Pods per second. This extreme scalability is made possible by architectural innovations such as a strongly consistent API server watch cache and a proprietary key-value store based on Google's Spanner distributed database.

Bytes before FLOPS: your algorithm is (mostly) fine, your data isn't

The author shares their experience in optimizing performance by focusing on data, including visualizing data flow, transforming suboptimal data, and specializing algorithms to suit specific data. Key techniques include reducing data access, using streaming non-temporal writes, compressing types, and vectorizing algorithms, which can lead to significant speedups.

Inside Rust's std and parking_lot mutexes – who wins?
