Notes on real-time voice AI, telephony, small language models, and building things.https://disolaterx.com/en-ushttps://disolaterx.com/writing/prompt-as-interface/https://disolaterx.com/writing/prompt-as-interface/What I learned cutting a small model's prompt nearly in half while making it more accurate — by treating the prompt like an API instead of a wish.Tue, 12 May 2026 00:00:00 GMTLLMsPrompt engineeringVoice AIhttps://disolaterx.com/writing/faster-is-not-better/https://disolaterx.com/writing/faster-is-not-better/A denoiser that was 2.5× faster looked like an easy win — until I measured the thing that actually mattered. A short note on benchmarking what you care about.Tue, 05 May 2026 00:00:00 GMTAudioBenchmarkingMachine learninghttps://disolaterx.com/writing/the-bug-was-not-in-your-code/https://disolaterx.com/writing/the-bug-was-not-in-your-code/A mid-call audio dropout that had nothing to do with audio — and what it taught me about debugging real-time systems on shared infrastructure.Wed, 22 Apr 2026 00:00:00 GMTReal-time systemsKubernetesDebugginghttps://disolaterx.com/writing/zero-downtime-stateful-deploys/https://disolaterx.com/writing/zero-downtime-stateful-deploys/A rolling deploy was killing in-flight queries during the drain window. The fix was one line of YAML — but only once I understood how the pieces shut down.Mon, 20 Apr 2026 00:00:00 GMTKubernetesReliabilityPostgreshttps://disolaterx.com/writing/cloud-queue-to-self-hosted/https://disolaterx.com/writing/cloud-queue-to-self-hosted/Swapping a managed cloud message queue for a self-hosted one inside the cluster cut latency and cost — but it handed us back a few things the cloud was quietly doing for us.Sun, 01 Mar 2026 00:00:00 GMTDistributed systemsQueuesArchitecturehttps://disolaterx.com/writing/typed-cdr-registry-in-go/https://disolaterx.com/writing/typed-cdr-registry-in-go/Call records come in a dozen flavours, each with different fields and lifecycle. A registry pattern keeps the decoder open to new types — and turns the one ugly exception into a documented invariant instead of a special case.Sun, 01 Feb 2026 00:00:00 GMTGoArchitectureTelephonyhttps://disolaterx.com/writing/voice-pipeline-in-go/https://disolaterx.com/writing/voice-pipeline-in-go/A real-time voice pipeline written in Python hits a ceiling at moderate concurrency. Rewriting it in Go bought roughly 10× the throughput per machine — but the real work was the benchmark that told the truth.Mon, 01 Dec 2025 00:00:00 GMTGoReal-time systemsPerformance
