apple notes , walk back those numbers

Of course, when Apple Notes added math, I thought and still think it’s really clever. But noticing just now a good reason to check the math haha 😅 I was checking some walking pace analysis because for some reason haha, my Strava doesnt consider walking a work out so it doesnt give you pace popped into Apple Notes, 12:18 minutes /0.56mi ‎ = 32.143 minutes/mi 45:10 minutes / 2.21mi ‎ = 4....

Argumentum Computem ad Infinitum

About a year ago, 2024-08-22, I was reading Leopold Aschenbrenner’s post1 on AGI and I had jotted down a musing about a scaling law observations, but I forgot to write about it. I found my note today. So I get that it is possible to look at charts comparing compute and performance and many conclude scaling laws mean AGI is inevitable. I like Yann Lecun’s perspective here that if transformer models are giant lookup tables, then making them bigger will make them appear more impressive, but this is not sustainable....

a life worth underthinking?

Cal Newport’s So Good They Can’t Ignore You from maybe over 10 years now, conveyed that Steve Jobs was using hindsight in recommending you to follow your passion. Don’t be a firefighter, astronaut or ballerina. Just do what let’s you put food on the table. Cal’s later work is on doing reducing distractions and slowing down to meet your aims; less is more. Did Cal end up asking you to focus after all?...
