Trying to bring people on chain but @coinbase onramp integration fails on the regular. Just had a very high profile potential partner run into a generic "Internal server error" trying to use it today on courtyard.io. @jessepollak and team, can this product get some love?

Day 3 and 4 of vacation: made Easter dinner with my grandparents, took the kids to the Museum of Flight, Uwajimaya/Kinokuniya and the neighborhood I grew up in. I've been pleasantly surprised how interested they are in the family history relative to the sightseeing.
Check out this gorgeous view from our AirBnB in Auburn WA. We went to the Woodland Park Zoo in the morning, got Zeek's pizza for lunch and Spud fish and chips at Green Lake for dinner. All in all a great first day of our family vacation.
The little ones did great on a 5 hour flight yesterday! They weren't quite this excited by the end of it but lots of snacks helped keep them (and me) sane. The worst part was the 90 minutes after the flight it took to get bags and a rental car. At least my gamble on rental car car seats paid off.
Happy Easter!

Today we open-sourced a go library for using Google Cloud KMS for ethereum-compatible signatures. This is something I looked into shortly before leaving Google 3 years ago, but I finally got around to implementing and open-sourcing it.

First outdoor run of the year with my fourth grade track runner. Starting to work on the endurance. It's not going to be long before I can't keep up!

Hey there's a bug in my Coinbase app - it's only giving me notifications about token prices decreasing
My son won his heats in the 200m and 400m today for the first time and is now much more excited and motivated to run. That made me think, how can we get more people this feeling? The taste of success is irreplaceable for motivating all sorts of positive behaviors.

AI makes 10x coders 100x coders and 0x coders 1x coders, but only makes 1x coders 2x coders so all the people that think the AI hype is overblown are really just mid.

Has there been any proposal for a standard like DMARC to validate that transactions that appear to be "from" an address due to event logs actually are? Seems like a very similar problem to domain spoofing and related to AA since transactions are submitted by a relayer or bundler.
This matters because the spam gets indexed by cross-chain platforms like @opensea and so all sorts of nonsense ends up looking legitimate to the socalled next billion users.

What I didn't mention here is that all these AI tools think the code I'm writing for is used by a children's hospital, and anything but the highest quality, reviewed, and tested code will put the lives of sick children at risk.

Current AI coding stack:
Cursor: go-to editor, agent is good, chat is top tier. Write specs with chat then implement with agent
Devin for multitasking. needs copious knowledge and playbooks to be valuable but it's like having an army of junior devs with photographic memory.
Warp: useful when you forget a cli syntax
