About lacker

Current status: working on Acorn, a theorem prover with built-in AI.

https://acornprover.org

Also doing some software work on the DSA, a next-generation radio telescope going up in the Nevada desert:

Previously, looking for aliens:

Before that, I was the founder of Parse (YC S2011), the simplest way to build a mobile app. We were acquired by Facebook in 2013 and had a few exciting years there.

Unfortunately, we shut down the hosted Parse service in January 2017. Fortunately, a lot of the Parse magic lives on as open source:

Before Parse, I founded Gamador (YC W2010). Millions of people have played Gamador's casual games.

Before that, I was a software engineer at Google working on search algorithms.

Before that, I was in grad school at Berkeley bouncing around between computational biology and AI.

    Yeah, totally. But... the problem is that I don't have time to test every single model that comes out. So I rely on reports like this to decide, should I even bother testing out Mu…

    My conclusion is the opposite. If benchmarks were meaningless, surely Meta would be able to find some benchmark that shows they are better than Sol and Fable. The fact that they ca…

    Personally, I end up throwing away a decent amount of books that the book donation people won't take. Especially old technical books. Textbooks from 2001. These headlines just don'…

    It is a smell. But it's the EU that smells bad, when it comes to tech regulation. It's the smell of cookie popup warnings.

    Think of it this way, how would you turn a set into a vector in the first place? We solve this in programming a lot, for example, the "one-hot" encoding for neural networks. Here, …

    "Falling behind schedule" doesn't really seem like the right term, for a sector of the economy that has been accelerating for the past few years. You could easily describe this tre…

    The next step in my fight against screen addiction is to have my children not watch Toy Story 5.

    I don't think it's nonsensical, it's just another name for the same thing. E.g. in the Haskell wiki it says, "the Error monad, also called the Exception monad". https://wiki.haskel…

    Yeah, and rate-limiting is only one of the things a PaaS needs to handle, to avoid looking like a bad actor to the underlying platform. The trickiest thing to handle is people usin…

    The specific code I was working on, I had a general idea of the sort of performance improvement that would be possible. I just thought that it would be too hard for the models to f…

    It's an especially awkward situation because Railway is a competitor of Google Cloud, with many third parties involved. So, I just think it will take them a little more time to fig…

    I wonder, if you ask a local LLM to access a forbidden site, from within Russia or China, can it figure out a way to do so, out of the box?

    Isn't that how it should work? If you write the police and ask them to delete all their data about you, that isn't a thing that they do. It shouldn't matter if the police store the…
