Without it, APIs are exposed to abuse, resource exhaustion, and unfair usage.
That’s why I built a production-ready, thread-safe rate limiter library in Go, based on the Token Bucket algorithm.
I chose the Token Bucket algorit...

It was mid-2016 when I first put on glasses. Myopia and astigmatism - two words that would become permanent companions in my life as a developer.

felt my IQ go up just by talking to Claude Code today. We were discussing low-level optimizations for my allocator.
Me: "I see. So using intrinsics is basically calling raw CPU instructions directly from C?"
Claude: "Exactly. It goes like this: C Code → Compiler Intrinsic → CPU Instruction"
Here is the quick mapping list we discussed:
Use Case,GCC/Clang Intrinsic...

We’re told this is necessary.
That intelligence must be centralized.
That your thoughts are safer once they’ve been absorbed.
That is the system ...
