Tales from the Developer: Troubleshooting and fixing issues with Varnish

When things go seriously wrong in a well-built but complicated system, the cause is often a cascade of small failures that pile up. Not that we’re building rockets over here, but an excellent example is the ill-fated Ariane flight V88. Solving the issues behind such failures can be problematic. Many things contribute to the difficulty, from the extensive use of caching to the need to convincingly reconstruct the failure in retrospect. Debugging this kind of failure, especially under pressure, is hard. We consider the ability to do this to be the hallmark of a senior developer. Even so, it is essential to have a team of experts working together to troubleshoot issues and find solutions promptly to help keep your site running.

The Toxics Use Research Institute (TURI) at the University of Massachusetts Lowell wanted to add memos to records in its Pollution Prevention Options Analysis System (P2OASys), a database for evaluating and comparing the safety of chemistries.

Turbo charge your Mac development environment

Last year, I switched from developing on a dual-boot Windows and Linux machine to working on a Mac. During the transition, I felt my productivity slump: not only was I missing keyboard shortcuts that I had become very accustomed to (such as Alt+←, for instance), but some native MacOS behaviour drove me crazy (like ⌘+Tab cycling through applications rather than cycling through windows of all applications). I also found the Mac terminal to be lacking, missing important utilities, and running some outdated binaries. So, vowing to prove decisively the superiority of humans over machines, I decided to make my Mac Just Work* ™  * Like my PC used to.
