LLM Model Routing in 2026: The Guide Every Team Should Read
40+ min ago (1655+ words) Most teams still pick one LLM and send every request to it. That worked in 2023 when there were three viable models. In 2026, with dozens of frontier, mid-tier, and specialist models — each with different pricing, latency, and quality profiles — committing to…...
Scaling Event-Driven APIs: Real-Time WebSockets and Redis Pub/Sub for High-Concurrency Apps
1+ hour, 4+ min ago (480+ words) From a business perspective, system instability during peak usage events directly damages user retention, degrades brand trust, and triggers SLA violations.

2+ hour, 51+ min ago (415+ words) gh api --paginate --slurp --jq 'length' is the command everyone reaches for to count issues in a repository. It does not count issues. It counts pages. I found this while writing pagination recipes for a toolkit, and then found the…...
Treating “one day” as a system primitive
3+ hour, 38+ min ago (165+ words) For most AI apps, the unit of time is a request. A user sends a message, the model responds, and the workflow ends. Cogweald is designed around a different primitive: one real day. Each world can advance by at most…...

tokeneff: An Open-Source LLM Cost Meter That Runs Locally
4+ hour, 2+ min ago (338+ words) Most LLM dashboards show you the bill after the damage is done. You run a coding agent for an afternoon, ship a feature, and two days later your OpenAI dashboard says you spent $47. On what? Which model? Which request? You…...
Database Isolation Levels: What Can Concurrent Transactions Actually See?
1+ min ago (743+ words) Transactions do not execute in isolation from reality. Isolation levels define how much of that reality they are allowed to observe. In the previous topic, we explored Optimistic and Pessimistic Concurrency Control. Now we can go one level deeper. What…...
