Speculative Debugging, Planned and Unplanned Work, Legible News, and Ops Lessons
- Reverb — speculative debugging for web applications. […] Reverb has three features that enable a fundamentally more powerful debugging experience. First, Reverb tracks precise value provenance, allowing a developer to quickly identify the reads and writes to JavaScript state that affected a particular variable’s value. Second, Reverb enables speculative bug fix analysis. […] Third, Reverb supports wide-area debugging for applications whose server-side components use event-driven architectures. (via Morning Paper)
- Planned vs. Unplanned Work (John Allspaw) — Planned work comes from experience, and experience comes from unplanned work.
- Legible News — scraped from Wikipedia’s current affairs section, and presented in a wonderfully minimalist fashion.
- Ops Lessons We Learn the Hard Way — Your network team has a way into the network that your security team doesn’t know about. (via BoingBoing)
