Building KOS: A Journey Through Zero Dependencies (And the Bugs That Taught Me Everything)
I didn't set out to reject go get. I just wanted to build something clean. But somewhere between the first snapshot corruption and the fourth complete rewrite, I realized: zero dependencies wasn't a constraint. It was a feature. This is the real sto...

Go Slice Initialization Gotchas: The Hole-Creating Bug I Keep Seeing (And a Linter That Catches It)
Go slices are simple on the surface. Under the hood, the interaction between length, capacity, and append has a specific failure mode I've been bitten by more than once — and seen in enough code reviews to write about. The bug is invisible at compile...
