LiteLLM is the glue a lot of us reach for when an app has to talk to more than one So I built fast-litellm: a drop-in Rust acceleration layer that swaps the hot I am going to lead with the numbers, including the ones that did not go my way. Component Result Connection pool 3.2x faster (lock-free Das
Most webhook tutorials stop at app.post('/webhook', ...), log the payload, and call it a day. That works for a demo. It does not work for production. The business logic in a Stripe or GitHub webhook is usually the easy part. The annoying part is everything around it: verifying signatures managing se
Every Claude Code power user has a story: the force-pushed main, the "helpfully" rewritten .env, the API key committed at 2am. The fix has been sitting in the docs the whole time — hooks: shell scripts that run on every tool call, outside the model, so they hold even when the model has a bad day. Al
Observability Practices in Action: Instrumenting a Node.js API with Metrics, Logs, and Traces It's 3 AM. An alert fires. Checkout latency spiked, and orders are failing intermittently. You SSH into a server, grep through log files, and hope you find something before your coffee gets cold — or before
Open a Japanese sentence in a narrow column and watch where the browser breaks it. It will happily split 特定商取引法 into 特定商取引 / 法, or push a 。 to the start of the next line. Japanese has no spaces, so the default line-breaker treats almost every character boundary as fair game. To a Japanese reader tha

The instructions included one sentence that I didn't think much about at the time: "Extensions must be configured when the mint is first created; you cannot add them later." At the time, I treated it like an

But by the time December invoices processed, $2,087 had quietly exited through the back door — 12 customers who didn't renew
Prompt caching turns context order into runtime architecture. Moving a timestamp, session id, memory write, or even tool schema to the front of an agent’s prompt can single-handedly destroy the cache economics of every long-running task. This still causes trouble even though the model does answer th
In spring 2023 I had a spontaneous lung collapse. I spent a week in a hospital bed with a tube in my chest and about two months recovering afterward. At some point during the recovery I opened Coursera and started the Google IT Support certificate. Not because I had a plan. Because I finally had tim
Your team ships a documentation chatbot. It retrieves chunks, stuffs them into a prompt, and generates an answer. Demo day goes great. Then a customer asks "what's the rate limit for the batch API?" and the bot confidently answers "10,000 requests per minute" — citing a doc about a completely differ
As enterprise generative AI transitions from simple, conversational chatbots to autonomous multi-agent workflows, developers face a critical bottleneck: scale. In a production environment, an enterprise agent often needs to navigate hundreds of heterogeneous data structures, dynamic business rules,

The call came in at 2am. Not a page, an actual support recording, flagged by a customer who said our voice agent "hung up on her mid-sentence." I pulled the trace. The LLM call was perfect. 380ms, clean completion, sensible response. Every dashboard I had was green. The customer was still angry, and
