OpenAI found two unrelated bugs masquerading as one in ChatGPT's data infrastructure. Silent hardware corruption on one Azure host and an 18-year-old race condition in GNU libunwind's setcontext function with a one-instruction vulnerability window. The breakthrough came from switching to population-level crash analysis rather than examining individual core dumps. By Steef-Jan Wiggers

Cloudflare has recently shared how they uncovered an issue in their Rust implementation of CUBIC, a congestion controller algorithm, which prevented it from recovering from a scenario of heavy packet loss at the start of a connection. By Gianmarco Nalin

This article was originally published on aicoderscope.com TL;DR : Cursor Tab (the inline ghost-text autocomplete) breaks in 8 distinct ways. Roughly 70% of cases are fixed in under a minute by checking three things: the toggle in Settings, your extension list for Copilot, and your usage quota. The remaining 30% need a corporate proxy fix or a toggle-restart cycle. After this guide you will: Know which of the 8 root causes matches your specific symptom Have the exact settings path and command for each fix Understand the 2,000-completion monthly cap on the Hobby plan that silently kills suggestions at month-end Honest take : Every "Cursor Tab is broken" thread in 2026 falls into one of these eight buckets. Go through the three-step quick check first — most readers fix it there. The 60-second triage: three checks before anything else Open Cursor and verify these in order. They resolve 70% of cases. 1. Is Cursor Tab actually enabled? Press Ctrl+Shift+J (Windows/Linux) or Cmd+Shift+J (Mac) to open Cursor Settings, then go to Features > Cursor Tab . The toggle should be on. If it's off — and this happens more than it should after updates — flip it, restart Cursor, done. You can also check from the status bar at the bottom right of the editor. A small "Tab" indicator shows whether inline completions are active. If it shows disabled, click it to re-enable. 2. Have you hit the free quota? On the Hobby plan, Cursor gives you 2,000 tab completions per month . During active coding at a normal acceptance rate, you can burn through 50–100 per hour. If you're late in the billing cycle, open Settings > Usage & Limits and check the completions counter. Completions reset on your account anniversary date, not the calendar month. When you hit 2,000/2,000, tab completion stops silently — no error, no banner, just nothing appearing. Upgrade to Pro ($20/mo) or wait for the reset. 3. Is GitHub Copilot or Tabnine installed? If you migrated from VS Code with extensions intact, you may have G
