I bought a house a year ago and now my neighborhood is considered the coolest neighborhood in the US and #5 globally. My cat thinks it's because of her.

I'm excited about the potential of AI, but it is crazy that NVidia is 5x Exxon's market cap.

What do you want to know?.

My cat brought me one of her toys when I was playing Beatsaber in VR. I'm pretty sure she saw me waving my arms around in the air, and thought I really needed a toy to play with.

Theorem provers can be concise. Fast memory safe array duplicate checking in a tweet. def allDiff [BEq α] (as : Array α) : Bool :=. ∀(i : Fin as.size) (j : Fin i),. have _ : j < as.size := j.isLt i.isLt. as[i] != as[j].

What do people at small orgs do to benchmark user experience for non-web apps?. Benchmarking just on my own machine doesn't seem adequate.

Buying a new house in Portland, and this is what AI says my neighbors will look like:

Dog fashion show in PDX today:

I have this mint plant that responds to change very quickly. I rotated it yesterday morning and it's already growing towards the light.

I asked ChatGPT to write a proposal for a FM solicitation, and it responded with a proposal for additional LLM research. LLMs really are trying to improve themselves and replace us! 🤖.

It's ironic that there is all this hype for AGI, but the "state of the art" tools are just really good at pumping out bullshit.

Scored major points with the tween today. Me: Let's go to a concert. Kid: I only want to go to a concert if it's Lizzo. Me: Lizzo has two concerts coming up. How about next week?.

Portland light rail felt especially weird last night. Only three other people on the train:.Guy 1 was incoherently yelling. Guy 2 ate a tub of ice cream with a combat knife for a spoon. Guy 3 was dressed to go rafting. They probably thought I was the strange one.

We've normalized preferred pronouns. How about normalizing preferred forms of address?. "In your office, you said I should call you Leo."."That was in my office. At my home, I’d like you to call me Dr. Marvin".

Child sent me a early xmas list asking for a cat -- a real one that is "alive and breathing". They want to help pick it out. My kid has learned the importance of a precise specification when dealing with an engineer.

I'm not a fan of this question either. I was in a powerlifting class last week where this was asked and I reluctantly answered "I speak Spanish, but poorly". Everybody after me gave a variant of "I speak Spanish fluently, and also. ". Why do so many try to one up each other?.

I had a great trip from Portland this week to the bay area for work. It took just over 3 1/2 hours from door to door. Due to traffic, a colleague's commute by car took almost that long. I'm grateful for remote work.

Now I'm going to finish some of the missing safety proofs and start looking at using the spec for verification.

I'm also a huge fan of the Lean package manager, Lake, after the experience. It was pretty easy to get it to compile a bunch of C code and link that into the Lean executable.

I picked Classic Mceliece because it was an interesting coding-theory based approach that I wanted to learn, and seemed to be the least likely to be broken. Interestingly, while working on the formalization, one of the other candidates, SIKE, was broken:.
