It serves as both a crude tutorial on ECFP and a demonstration of writing unmaintainable scientific code.

git rebase -i is not that scary

Git rebase -i is not intimidating; it simply opens a text file where you can plan commit operations like reword, squash, or drop. The process is safe because you can abort at any time, and old commits remain recoverable via the reflog or a backup branch. Rebase creates new commits rather than destroying old ones, making it a manageable tool for cleaning branch history.

ffi_call_plan caching for GLib

Anthony Green added a “call plan” to libffi that caches preprocessing work, reducing GClosure invocation overhead by 10-25%. A GLib merge request requires this newest libffi, and a separate patch adds frame-pointers to enable unwinding across ffi boundaries for profiling.

Query cycles: A compiler murder mystery

A Ferrocene team debugged a week-long CI failure caused by three interacting bugs: a Rust test using the unstable fn_delegation feature hung indefinitely, triggering a Kubernetes pod OOM kill and a broken SSH connection. The pod had to be manually deleted, and the root cause was traced to multiple combined issues in the compiler and infrastructure.

JEP 541: Deprecate the macOS/x64 Port for Removal

JEP 541 proposes deprecating the macOS/x64 port for removal in a future release to reduce maintenance costs, as Apple has transitioned to AArch64. The port will produce a configuration error unless the --enable-deprecated-ports option is used, and there is no guarantee it will build or function. The deprecation can be withdrawn if credible developers express a clear desire to maintain the port.

I got into YC by hacking it

A security researcher discovered that Y Combinator used Paxel to score founders and found a vulnerability that allowed anyone to forge and submit fake scores due to an unvalidated HMAC. After publicly disclosing the flaw, YC’s Jared Friedman patched it within hours and invited the researcher to attend Startup School, though a private disclosure 12 days earlier had gone unanswered.

Micro-SaaS Is Dead. Service With A Software Replaces It

Micro-SaaS is dying because AI enables anyone to quickly build generalized tools, and technical users are canceling subscriptions to create their own. The emerging model is “Service with a Software”: private, overfit tools built for a specific service that are never sold, making that service impossible to compete with. The author illustrates this by building a custom sharing platform for client work that would lose its value if generalized for sale.
