Let’s Encrypt recently generated new intermediate CA key pairs and certificates to enhance online security and speed. These new intermediates are replacing older ones that are reaching expiration dates. The new batch includes 2048-bit RSA and P-384 ECDSA intermediates. Rotating intermediates every three years improves security and prevents key pinning issues. Shorter lifetimes and randomized […]
William Zeng introduces a file cache Python module developed by Sweep, an agent engineering team, to save time debugging slow LLM calls. This file cache, different from Python’s lru_cache, stores values on disk rather than in memory for persistence between runs. The cache supports ignoring certain parameters for accurate caching and utilizes recursive_hash to hash […]
Astronaut Thomas P. Stafford passed away at the age of 93 after a distinguished career that included commanding crucial missions such as the dress rehearsal for the 1969 moon landing and the first U.S.-Soviet space linkup. Stafford’s legacy also includes being involved in the fixing of the Hubble Space Telescope and leading the famous Apollo […]
Euclid’s mission faces a unique challenge as ice begins to impact its vision in space, requiring a precise and innovative de-icing procedure to keep the optics ice-free. The gradual release of water molecules from the spacecraft components in the vacuum of space leads to ice formation on Euclid’s sensitive mirrors, affecting the amount of light […]
The author recently discussed their book on the Mindscape podcast with physicist Sean Carroll, mentioning an early reference to the “simulation hypothesis” dating back to 1968, challenging the commonly accepted 2003 date. The interview with Margaret Mead revealed discussions on self-improving AI systems and the prescient nature of her insights. Mead’s reflections on early cybernetics […]
