What a handshake asks of a server, the arithmetic of a reconnection wave, the fixes, and what our own handshake numbers do and do not show.Cold start is a recovery problemhttps://cameleer.ing/cold-start-recovery/2026-11-13T00:00:00Z2026-11-13T00:00:00ZA restarted or new server is at its weakest when it first takes traffic. Four clocks from process start to full speed, the arithmetic of recovery, the ladder of fixes, and what our own start-up numbers do and do not show.How to test your headroom before an incident: the degraded-fleet testhttps://cameleer.ing/degraded-fleet-test/2026-11-13T00:00:00Z2026-11-13T00:00:00ZA procedure for a staging fleet: lose a third of the servers, restart one under load, reconnect every client at once, offer more than the fleet can serve. What to record, how to read it, and the pass or fail lines to write first.Headroom: what is left when servers drop outhttps://cameleer.ing/headroom/2026-11-13T00:00:00Z2026-11-13T00:00:00ZThe Microsoft 365 outage of 12-13 November 2026 was the same traffic on fewer servers. How much a fleet survives losing part of itself is an efficiency property, and it can be measured before an incident.Code efficiency as a FinOps leverhttps://cameleer.ing/finops/2026-11-12T00:00:00Z2026-11-12T00:00:00ZMeasured milliseconds and megabytes turned into instances and dollars: Lambda execution time, memory and cold starts, node density, Fargate, with the arithmetic shown.When a rewrite pays off: a decision checklisthttps://cameleer.ing/when-to-rewrite/2026-11-12T00:00:00Z2026-11-12T00:00:00ZThe case against rewrites, the ones that worked with published results, the ladder from a setting to a full rewrite, and a checklist.AI-generated code and performance: what the evidence sayshttps://cameleer.ing/ai-code-performance/2026-11-12T00:00:00Z2026-11-12T00:00:00ZGenerated code ran 3.12 times as long in one benchmark: what EffiBench, Mercury, EvalPerf, PIE, METR and DORA measured, each with its limits.Wirth's law in 2026: measuredhttps://cameleer.ing/wirths-law/2026-11-12T00:00:00Z2026-11-12T00:00:00ZSoftware growth against hardware speed since 1995: page weight, input latency, single-core speed, and the counter-argument.
