Modernizing C arrays for greater memory safety: a case study in the Linux kernel
How to modernize C arrays for greater memory safety: a case-study in refactoring the Linux kernel and a look to the future C is not just a fancy assembler any more Large projects written in C, especially those written close to the hardware layer like Linux, have long treated the language as a high-level assembler. […]
Critical brain hypothesis: A physical theory for when the brain performs best
Over the last few decades, an idea called the critical brain hypothesis has been helping neuroscientists understand how the human brain operates as an information-processing powerhouse. It posits that the brain is always teetering between two phases, or modes, of activity: a random phase, where it is mostly inactive, and an ordered phase, where it […]
Tell HN: GitHub will delete your private repo if you lose access to the original
I was surprised to see this in my email today: > Your private repository baobabKoodaa/laaketutka-scripts (forked from futurice/how-to-get-healthy) has been deleted because you are no longer a collaborator on futurice/how-to-get-healthy. That was an MIT-licensed open source project I worked on years ago. We published the source code for everyone to use, so I certainly did […]

Reducing Go execution tracer overhead with frame pointer unwinding
The Go Execution Tracer (aka runtime/trace) was designed to achieve low enough overhead to be usable on “a server in production serving live traffic”. This is achieved by writing events into per-P buffers, using RDTSC for timestamps, and encoding into a relatively efficient binary format. However, one achilles heel has remained since 2014: … 75% […]
New AI classifier for indicating AI-written text
We’re launching a classifier trained to distinguish between AI-written and human-written text. We’ve trained a classifier to distinguish between text written by a human and text written by AIs from a variety of providers. While it is impossible to reliably detect all AI-written text, we believe good classifiers can inform mitigations for false claims that […]
