Pretty much everything I use, you use, and we all use relies on Open Source in some way. The device you're reading this on probably uses OSS. We want that stuff to keep existing thriving, so in 2025 Sentry contributed $750k to the Open Source projects we use and love.

Like the rest of the internet, Sentry runs on Open Source. Like the rest of the @ThePledge 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 🧵

This administration is a scar on this country. Anyone supporting it is responsible - hold them accountable and stop doing business with them. That includes avoiding venture institutions and partners that actively participate and condone it. whitehouse.gov/aliens/

Shout-out to this headline from the verge I think about it whenever someone asks for a recommendation
It should NOT be this hard to buy a privacy-respecting printer. Seriously. A printer should be one of the simplest devices in the house. You send it a document. It puts ink or toner on paper. That should be the whole relationship. Instead, the mainstream printer market has become a swamp of cloud accounts, mobile apps, subscriptions, cartridge DRM, remote diagnostics, vendor lock-in, and “smart” features nobody asked for. HP is the canonical example of how bad this got. HP ties the printer to an HP account, an internet connection, and original HP ink for the life of the device. Dynamic Security can reject cartridges based on vendor-controlled firmware rules. Instant Ink turns printing into a subscription relationship. Why does it need to talk to the vendor just to do the one job it was built for? And from a security perspective, this is a nightmare. A Wi-Fi printer is a computer on your LAN. It has firmware, network services, a web admin panel, default settings, cloud features, and sometimes stored documents or saved credentials. A compromised printer can expose services. It can: - advertise itself to the LAN - store print jobs and scans - keep address books and scan destinations - hold credentials for scan-to-email, scan-to-SMB, scan-to-FTP, LDAP, or remote management And it usually sits on the same network as your laptop, phone, NAS, smart home devices, and sometimes work machine. Used printers are worse. Assume the previous owner left behind Wi-Fi settings, scan destinations, address books, stored credentials, and cached documents. One reason to prefer black-and-white: many color laser printers can embed machine identification codes into printed pages. Yellow dots are the famous version. The broader issue is forensic marking. Good intel on this is weirdly hard to come by.

We're getting closer and closer to software that heals itself. Excited about our collab with @AnthropicAI!

🗣️We just launched our Claude Agent integration Now when Seer finds a bug, it can hand it off to Claude—with all the context Sentry has about the issue—to write the fix and create a PR for you. Check out the docs for more: docs.sentry.io/organization/…

It's crazy how AI is really good at the stuff I don't know anything about and total dog shit at the stuff I do.
Replying to @stolinski

The biggest wildfire in Nebraska history is currently burning out of control. The governor called a State of Emergency and said “it's important that all Nebraskans pray.” In our 1st episode of Disasterproof, here's a Texas town that didn’t have to rely on luck or prayer.

Temporarily undid this, lost an hour scrolling bullshit without even thinking about it. I put it all back in place as soon as I snapped back to reality. Can't recommend it enough: as much as you can, make the Internet a place you have to physically move to go to.

I blocked all social apps on my phone a month ago, only allowing them on my laptop. Now X/insta/etc are places I have to get up and *go to*, instead of ever-present sirens in my pocket calling me to crash into distraction. A , highly recommend.

Obsessed with this Meowth card from the set that releases next week. The buildings in the back are a nod to cerulean city from Pokemon Red/Blue (the roof colors being another nod) Tempted to send it off for grading just because I love a good Easter egg.

THIS IS SO WILD
Tornyol (@tornyolsystems) is building micro-drones that kill mosquitoes. They use smartphone microphones, car park assist sensors, and some clever DSP and control to transform 40-gram toy drones into mosquito killers.
