>> How do programmers here account for the unexpected? I work on systems that need to run reliably. However, they depend on data collectors (like sensor data or web scraping) that are not known for their reliability or scalability. We do lots of retries, log errors and failures, and patch problems until things work as expected. One thing that helps is the use of sentry.io . It alerts us about exceptions and detects regressions/regression fixes by checking if there were any commits that might have caused or fixed issues.
