Like the rest of the internet, Sentry runs on Open Source. Like the rest of the @opensourcepledge.com companies, we also believe in paying it back.

In 2025, we gave out $750k to the OSS projects we rely on; here’s a sampling of some of them, and why they are so crucial 🧵

feels like latest macos completely broke my screenshot workflow. I used to be able to launch screenshot, drag, and have the image ready in my clipboard to paste. Now it is... not that x.x

how do I go back to the happy fun times?

Just finished Stranger Things; thing pulled some tears for sure. For something a lot of folks write off for being too predictable or corny or nostalgia fueled, someone else said this but, I think the Duffer Bros understand nostalgia as a kind of grief.

European Engineering is Unreasonable Persistence.

ASML goes hard; and globalized research is very good imo. Every dunk on european tech is silly to me. So much has been achieved through Zeiss, ASML, Nokia, Spotify, Wise, and more it's wild to think about.

The speed of react compiler and the corresponding eslint plugin is what currently blocks adoption at @sentry.io. Dev startup time went from a couple of seconds to 40 seconds, linting time doubled to over 4 minutes!
Had an 'upgrade to vite 8' PR running for a few weeks, and got it feature complete. Here's the rough difference in build timings for our vite projects in a monorepo from 6 -> 8.

Looking like the react compiler is now ~90% of the build times for puzzle.com

Testing out the Arrtx acrylic markers I got from @sean.thenewells.us for Christmas. We got Pikman4 for the family (which we are all enjoying) so wee critters have been all I want to draw/make.

CSS cascade layers are the most underrated feature of modern CSS. They're why semantic classes work now when they failed before.
