The Contagion of Fear

  • Students spread panic by warning of computer virus
  • AI expert Jacob Coxon claims 10% AI killing humans risk
  • Fear of AI driven by experts' speculation over reality

At the edge, the number that matters is memory - not throughput (specially in Ramageddon)

We rebuilt LF Edge eKuiper in Rust and ran it against eKuiper, Telegraf and Redpanda Connect on five real MQTT workloads โ€” one core, 1 GB of memory, and output checked message-by-message.

  • Memory usage, not throughput, is key metric in resource-constrained environments
  • Rekuiper, Rust-based engine, maintained memory usage between 5 and 10 MB
  • Design choices include bounded queues, incremental window aggregation, offline sink cache

API Rate Limiting: What Actually Breaks When You Get It Wrong

Most teams add rate limiting to their API as an afterthought โ€” usually right after something has already gone wrong. A scraper hammers an endpoint, a client integration goes into a retry loop, or aโ€ฆ

  • Simply setting a single request limit is insufficient as all requests don't have equal costs.
  • Centralize rate limit counters across multiple instances to prevent overloading the system.
