- 5Cloudflare Blog·10/5/2026product_launchCloudflare interns ship production work across internal tools and customer products
Cloudflare says it has hosted 750 internships across 48 teams as part of its plan to hire up to 1,111 interns in 2026. The company reports that interns used AI to ramp up faster and delivered shipped work in areas including cache optimization, the EmDash blog CMS, compliance automation, and post-quantum cryptography visibility.
- 5Hacker News·9/8/2026researchStudy compares testing techniques for coding agents
This Hacker News post describes an evaluation of how coding agents perform when explicitly instructed to use different testing and verification techniques while implementing Zstd in Rust. It compares 26 prompting conditions, including TDD, property-based testing, fuzzing, formal methods, and several Rust testing tools, plus a few skill-based variants. The author also reports additional smaller evaluations, such as one based on the IMAP RFC.
- 7Cloudflare Blog·9/1/2026researchCloudflare tests Zstandard cache transcoding to expand cache capacity
Cloudflare says it prototyped Cache Transcoding, a system that compresses eligible cached assets with Zstandard before storing them on disk and moving them between data centers. The company reports this can cut eligible assets to about one-third of their original size on average, trading a small CPU increase for lower storage use and less cross-data-center bandwidth.
- 5Simon Willison·8/9/2026researchSQLite prototype for compressed text revision history
Simon Willison describes an experiment for storing full text revision histories in SQLite as a compressed JSON array of prior versions. A prototype using Zstandard reportedly reduced 20.4 MB of simulated revision text to 80.3 KB, with a suggested optimization of splitting history into smaller chunks to avoid repeated full recompression.
- 6Hacker News·7/26/2026researchLLMs May Automate Proofs in Dependently Typed Languages
The article argues that large language models, combined with proof irrelevance, could significantly reduce the manual effort required in dependently typed languages. It describes a Lean-based experiment building a Zstandard decompressor to test whether LLMs can make proof automation more practical and lessen proof engineering overhead.
