🎉 New music nerd tool: bops․fyi. Import your *entire* Spotify stream history (9 years of data for me!). See fun/terrifying facts about your music (that Spotify Wrapped won't show you).

Should countries like Germany or Spain consider acquiring a nuclear deterrent, like France and the UK have? I feel like a lunatic saying this out loud, and it's probably still a bad idea on balance. But countries should plan for the potential of radically more dangerous futures.

I built a simple calculator for the Merton share: how much of your wealth should be in stocks, according to a simple economic model? (Link at end of thread)
It accounts for the present value of your future savings, not just what you have now.

Dividing by zero breaks deterministic calculations. Dividing by a distribution that spans zero does the same thing to Monte Carlo simulations. But it's harder to notice.
This is a SUPER common mistake with uncertainty modelling. I've seen it many times from Carlo customers.

What follows is a real deep cut, but: Anthropic has finally fixed "Thinking may not be enabled when tool_choice forces tool use"
So we can remove some special-case code in our FrontierMath eval!
If you are the engineer at Anthropic who worked on this, show your boss this tweet

Deep Learning has hit a wall.
OpenAI's much-hyped "o3" model is so dumb, it doesn't even know
on what day, month, and year Olton Willem van Genderen (the Surinamese civil servant and politician) died!
Yet, Dario Amodei has been silent about this. Curious.

Moskovitz’s coefficient? You mean from Moskovitz (2011), the factor that turns a planetesimal’s radius into its approximate conductive cooling time, showing how long a hot body takes to shed its heat?

This is the most impressive thing AI has done for me in several months. I actually gasped.
Completely correct answer I hadn't considered at all, and that might have taken me hours (days?) to find.
Wrong hypotheses in my prompt didn't sidetrack AI

In their eval of Claude's political "even-handedness", afaik Anthropic doesn't report the breakdown by category (political figures/parties, social issues, US constitution, science, social/identity issues...). I think that would be interesting.

I just fixed a rare autosave race condition in intentions.page from the React rewrite I did in March of this year.
Today's AI is smart enough to find the bug in the React slop it wrote 7 months ago.

Sonnet 4.5 sets a new SOTA of 65% (±2%) on SWE-bench with our scaffold (based on SWE-agent). The new model beats Sonnet 4 by 4 percentage points.
Eyeballing the plot, the SOTA improvement seems to be slowing down, compared to the progress we saw between Sonnet 3.5 and Opus 4.
