When I was first starting out in software engineering, it felt like there was a never-ending barrage of tooling to learn. After more than a decade in CLI environments, I still find myself constantly learning new features and fun facts - but it’s fairly rare that I learn something new that I end up using day-to-day. I wanted to share some things I learned at relatively late stages in the game that ended up being significant productivity boosters for me - perhaps some of them are well-known, but in the spirit of this XCKD, I hope that someone reading this might pick up something new.

Most popular DBMS like MySQL [https://dev.mysql.com/doc/refman/8.0/en/mysql-acid.html], PostgresSQL [https://www.postgresql.org/about/] and Oracle [https://docs.oracle.com/cd/F51125_01/docs.85/SDS%20PI/acid-compliant-transactions.html#GUID-ECB79D66-46DE-4F48-93DC-8677E7BB44EF] have ACID guarantees out of the

Making changes to websites is tricky, because even small changes may lead to visual regressions in the page layout. For example, changing a bit of CSS to fix something somewhere may blow up in a completely different place. I could just click around and make sure everything looks okay, but that is boring and error-prone. What if I told you that there is a way to make sure that every pixel on your site is perfect, staying just they way you intended it to be?
