7 vulnerabilities in django-allauth enabling account impersonation and token abuse The django-allauth package had seven vulnerabilities, including four major ones that enabled account impersonation by exploiting mutable or non-unique identifiers from Okta and NetIQ, token refresh for deactivated users, and unverified email acceptance from Notion. These flaws could allow attackers to impersonate users and abuse tokens, but all have been fixed in version 65.13.0. https://zeropath.com/blog/django-allauth-account-takeover-vulnerabilities

How often does Python allocate? The article explores how frequently Python allocates memory, focusing on the integer type implementation. It finds that CPython allocates new memory objects often but mitigates overhead by reusing objects from a freelist and employing a specialized pool allocator; nonetheless, Python's integer handling still incurs considerably more allocation overhead than the single CPU ADD instruction... https://zackoverflow.dev/writing/how-often-does-python-allocate

Decompression is up to 30% faster in CPython 3.15 CPython 3.15 introduces significant improvements in decompression speed: Zstandard (zstd) decompression is now up to 25–30% faster, and zlib decompression is 10–15% faster for data larger than 1 MiB. These gains result from optimizations in the handling of output buffers during decompression. https://emmatyping.dev/decompression-is-up-to-30-faster-in-cpython-315.html

Build better software to build software better The article from Slack Engineering describes how Slack improved their build pipeline by applying classic software engineering principles combined with high-performance build tooling (Bazel). They restructured their build system by separating concerns, modeling builds as graphs of well-defined work units, and leveraging caching and parallelization, which resulted in builds running up to s... https://slack.engineering/build-better-software-to-build-software-better
