Every once in a while I still get hit over the head and realize programming will never be the same. Instead of writing deterministic code with strong backgrounds in algorithms, it’s going to be who makes the AI feel better about itself and willing to answer queries better.

This paper is wild - a Stanford team shows the simplest way to make an open LLM into a reasoning model They used just 1,000 carefully curated reasoning examples & a trick where if the model tries to stop thinking, they append "Wait" to force it to continue.

If we really do take control of Gaza, we should build a technology corridor there and work with Israel to have a totally open border for trade and work, so that we can have Israelis working “in the US” on technology from Israel with no restrictions or red tape whatsoever.

Interesting to think about the difficulty in creating *good* evals.

While MoCA is the standard, it’s still not very good. But this is objectively hilarious.

Susceptibility of large language models to cognitive impairment. #bmj "With the exception of ChatGPT 4o, almost all large language models subjected to the MoCA test showed signs of mild cognitive impairment." www.bmj.com/content/387/...

Oregon v Ohio State on New Year's Day at the Rose Bowl is oddly familiar. Oregon v Ohio State, both Big Ten teams, playing in the CFP quarterfinals is oddly different.

Startup hilarity: Us: how many members do you have? Them: about half a million. (the next week) Us: remind us, how many members do you have? Them: about a million. (the next day) Us: so those million... is that currently enrolled? Them: oh no. We have 10 currently enrolled.

Case in point: It will never not amaze me that Stripe built a $100b business bc they simply had a better API and developer experience than anyone else.

Nice to see Goodbill listed in BI's 10 Startups Using AI to Disrupt Healthcare Payments. Lots of work to be done. We're steadfast in our mission to reduce hospital bill costs in this country and are chipping away at the problem a little bit at a time. www.businessinsider.com/startups-usi...

businessinsider.comThese 10 startups are using AI to disrupt healthcare payments as public outrage toward insurers mountsHealth insurers are increasingly denying paying for patient care. A growing crop of startups think AI can help.

My most favorite feature of using AI to write code is learning new methods and tricks. My least favorite feature of using AI to write code is finding out those methods and tricks don't work.

Hit 100 followers. Thanks for the support. One thing I like about Bsky is not worrying too much about what I’m posting. So expect a wide range of topics: * AI applications * Ruby/Rails * Judaism * Umich sports * Detroit * startups * bird dogs * fatherhood * Yellowstone * fly fishing

if there’s one thing meta is extremely good at, it’s knowing when to innovate and when to copy. they are ruthless in competition. it is as impressive as it is scary.

Social media is in desperate need of innovation. Meta is only letting you have a slice of control over what you see because Bluesky is here building for you.

i was extremely early to fb (user id 69 on school number 12 or so), super early to Twitter (user ID 5500), early to Threads (first few hours), but relatively late to bsky. iow: tell me you're in your 40s without telling me you're in your 40s.
