it is strategically and morally bankrupt to work to drive everyone who rejects the Omnicause away from supporting queer people. people with this attitude are unambiguously working to undermine gay and trans rights and they should be responded to accordingly

Forget trust stacking. The tax break for founding and investing in tech startups shouldn't exist at all. Capital already floods into venture without QSBS. Exempting up to $15 million in capital gain is a windfall for investors to do something they were already eager to do.

I know it's kind of stupid, but when something is 20% above its 200-day moving average, you'd need to see ~61% annualized return to maintain that distance. g ≈ 2Y / (N-1) (g is the daily growth rate; Y is the distance above moving average; N is the length of the moving

Believe in the length penalty. Parallel vs sequential tools, tool vs base model capability, single agent vs subagents, thinking strategy, truncation, doomlooping, exploration. You don't need new rewards, you need a better length penalty.

The US Government has requested a slow staggered rollout of GPT-5.6, and OpenAI has agreed. During this phase the government will approve each user individually. This will probably be the norm for all frontier models from all labs from now on.

currently the most effective way to be "data-efficient", and improve performance in a text task, given a small (eg 100-1000) dataset is to use it to select and iterate on an elicitation process that scores high for that dataset
