Cloud Run Concurrency: Size It With Math, Not Defaults
Cloud Run's concurrency default is a starting point, not a decision. Size it from your workload's CPU and I/O profile — here's the math, the failure modes, and how to verify.

cloudrunCrystal Fibers and Channels: Concurrency Without the Mutex Anxiety
Crystal's fibers and channels give you typed, backpressure-aware concurrency that reads like sequential code. Here's how the model works, a worker-pool example, and the pitfalls to avoid.
crystalIntermittent file busy errors during concurrent terramate generate on shared stack templates
Goal Determine whether concurrent terramate generate invocations writing to overlapping stack directories should serialize access through Terramate's template compilation pipeline, or whether each invocation manages its own filesystem locking. Constraints Terramate stores templates and generated HCL on the local filesystem. Parallel CI/CD runs or developer w

clojureStructuring I/O-Heavy Workers in Crystal with Typed Channels and Fibers
Crystal's typed channels and fibers make I/O-heavy worker pools read like plain blocking code — but fibers aren't threads. A worked example, backpressure notes, and the parallelism caveat.
Why Your SQLite App Locks Up Under Load — and What WAL Mode Actually Fixes
SQLite's default journal mode serializes reads and writes, causing 'database is locked' errors under concurrency. WAL mode fixes this with one pragma — here's how it works and when to avoid it.
