Went apple picking today. You never know where you’ll find unpatched OpenSSL in the wild.
A red apple with a heart-shaped patch of yellow-green that blurs at the lower edge. If you squint it looks like the Heartbleed logo.

[ASPLOS'25] Fusion: An Analytics Object Store Optimized for Query

Chris climbing Ridicullissima, a tall classic 5.10d in the Gunks. I photographed him while hanging from a rope anchored at the top. I experimented with anchoring the other end to the ground. It was awkward; I have a lot to learn. At least having two attachments prevented me from spinning.

Today I learned that Yahoo! is an independent company with over 8000 employees in 2025. I wonder what they all do?

I rewatched it a few years ago and realized it's not about computers, it's an allegory for realizing you're gay and finding your people.

I stumbled into a right-wing rally in London.
A few lads wearing the UK flag or the St. George's Cross flag as capes face a line of British police in riot gear with plastic shields on a rainy London sidewalk.

That’s right, I’ve found it. The holy grail, the one feed to rule them all, the aggregator for your whole Internet. None of these walled-garden rent-seeking websites want you to have it, but I’ll share it with you. emptysqua.re/blog/how-to-...
