Notes

Curated TIL (Today I Learned) notes from a DevOps Engineer on cloud infrastructure, automation, and anything I learn along the way.

Inspired by jbranchaud/til and simonw/til.

  1. Why PHP 6 Never Officially Existed

    PHP skipped version 6 because the project, which was primarily focused on adding native Unicode support, stalled due to complexity and performance issues. To avoid confusion with the failed effort and its associated books, the community voted to name the next major release PHP 7.
  2. Solving Amazon Data Firehose Bottlenecks

    When Amazon Data Firehose uses a Lambda for transformation, high data volume can exceed the AWS Lambda concurrent execution limit, causing processing delays. The most effective solution is to increase Firehose’s buffer size to reduce the number of Lambda invocations.
