  • The Event Stream Debacle

    The Event Stream Debacle

    By Eric Brandes on December 5, 2018

    Unless you were hiding under a rock, you probably heard about the “event-stream situation” on NPM this week. TLDR: the original maintainer of the event-stream package was tired of maintaining it. He handed over the reins to a different developer, who promptly injected malware and released a new version.

    Much of the ink spilled on this subject focused around open source expectations and who. was. responsible. for. this. happening. I don’t want to spend much time on this part of the discussion, so I’ll keep it short by saying the entitlement on display in that Github issue was remarkable. Imagine a scenario where someone gave $20 to everyone who wanted it. Some folks in that thread would be angry because it wasn’t $50.

    Application Versions

    By Eric Brandes on November 5, 2018

    These days it’s common to release new versions of a web application daily, or even multiple times a day. At any given time there could be multiple versions of a code base running live in production. A new version might be getting soak tested on a pilot server, while the previous stable version is being served to most customers. When it comes to JavaScript error monitoring, it’s important to know if a new application release is having issues that old releases were not. (Or whether a new release resolved a previous bug.)
