Watching Claude interact with Beads makes me never want to touch an issue tracker ever again.
I can easily imagine a future where I sit down, give Claude some instructions for the day, and zone out while it just ... churns.

Reminds me of the time when $startup had a massive outage and I flew coast-to-coast for Thanksgiving fighting fires the entire time. 🫠

Just the move from parquet to vortex gave us a massive perf boost. But more importantly, it opens up the path for way more. So much low hanging fruit now!
We completed a major project to switch our storage file format from Parquet to Vortex 🌪️ resulting in 70% average query performance improvement across the board 🚀
Learn more about how rethinking interface-imposed limitations unlocked these gains in our latest blog post 👇

Literally just ran into this. An entire page of results, only 1 of which was an actual organic result. 🫠
And its even worse than in the picture – the result was almost 2 scrolls below the fold and there were *more* sponsored results below it!

Another day, another new repository. This time it's a repo that mostly just contains a setup script to install YuniKorn + Karpenter w/KWOK provider in a local kind cluster so I can test auto-scaling and queue configs.

The UDR7 is in my shopping cart...let's see if eero survives another day.
1 night of sleeping on it before finally giving up on Eero. They used to be so good, but my latest issue is just weird wifi speeds down to 5Mbps. ¯\_(ツ)_/¯

Haven't read it yet, but looks to be a good repo with Talos + K8s homelab setup. www.reddit.com/r/kubernetes...
I particularly like the example of exposing excalidraw.
