Codetown ::: a software developer's community
Ivar came to the Swamp for the #j4kio conference a few days ago. He had just been in South Africa giving a presentation. And, just before that, we met up in Crete for the fabulous www.jcrete.org conference. #jcrete How about that! Ivar lives in Sweden. He keeps fit and always rents a car wherever he goes so he can explore the area. In just a few days, if you missed the www.j4k.io conference, there will be similar talks, including Ivar, on a virtual Jakarta webcast. That's Aug 10th. I'll put the details up on www.Codetown.com. Ivar, great seeing you!

Anthropic released Claude Haiku 4.5, making the model available to all users as its latest entry in the small, fast model category. The company positions the new model as delivering performance levels comparable to Claude Sonnet 4, which launched five months ago as a state-of-the-art model, but at "one-third the cost and more than twice the speed."

Anthropic's Alignment Science team released a study on poisoning attacks on LLM training. The experiments covered a range of model sizes and datasets, and found that only 250 malicious examples in pre-training data were needed to create a "backdoor" vulnerability. Anthropic concludes that these attacks actually become easier as models scale up.

Cloudflare's innovative Merkle Tree Certificates (MTCs) revolutionize WebPKI, enabling a seamless transition to Post-Quantum (PQ) cryptography without performance penalties. By minimizing TLS handshake overhead and integrating Certificate Transparency, MTCs promise enhanced security while addressing latency concerns, paving the way for future-ready internet security.

Researchers from Standford, Princeton, and Cornell have developed a new benchmark to better evaluate coding abilities of large language models (LLMs). Called CodeClash, the new benchmark pits LLMs against each other in multi-round tournaments to assess their capacity to achieve competitive, high-level objectives beyond narrowly defined, task-specific problems.
