@ploi heya! I was looking at your offering, and it's looking good! Any chance you're working on adding Dutch server providers such as Tilaa or TransIP? France and the whole world just got a bit darker. https://youtu.be/MV_3Dpw-BRY ★ 1 #protip: if you want to select something from a database, do not start your query with `seleect`. that won't work. ★ 7 Decided to put some leftover bandcamp codes on band.codes, so if anyone wants to grab my Elektroraum EP: https://band.codes/stefankoopmanschap/elektroraum ★ 3 Yay for having tests that catch a bug in a change in code. ★ 5 What to do when your old developer/development partner leaves? https://magma.dev/2026/06/the-orphaned-system/ #linktuesday ★ 4 if you haven't seen it yet, @dutchphpconference has my talk on sociocratic decision making available: https://phpconference.nl/session/how-to-make-good-decisions-with-a-happy-team/ ★ 4 Happy international non-binary people's day! ★ 2 Happy to announce I'll be speaking at #SymfonyCon Warsaw this November! It's going to be a brand new talk on improving inclusiveness: https://live.symfony.com/2026-warsaw-con/schedule Will I see you there? ★ 7 Last day of the CfP for @symfony con Warsaw! I just submitted two brand new talks. Have you submitted something already? https://live.symfony.com/2026-warsaw-con/cfp ★ 1
