LPisGood··on Google Search is now less than half of Alphabet’s revenue
Google Pixel / Android are very popular. Chromebooks also did well.
LPisGood··on Git for the US Code
Wow! This is very cool. I had an idea for something very similar to this when I found out the US federal government offered API keys, maybe three or four years ago. I found that while Congress did list bill revisions as they were made the format and retrieval of these was not an easy task. The idea was that I wanted to look at any line of any bill and see who proposed it that particular line’s inclusion.

For the record, and feel free to steal it if you like it, I called it “G(overnm)it-blame”

LPisGood··on The Exponential Time Hypothesis Is False [pdf]
Linear programming admits a worst-case polynomial time algorithm.

It is notable that simplex, especially dual simplex is often better in practice, especially for integer linear programming with branch and bound because you only have to slightly modify the parent optimal basis in simplex vs entirely restarting or refactorizing for interior point methods.

That is unfortunately not the case

> To be clear though, it does not imply that NP is subexponential

Is there a subset of NP problems for which a subexponential algorithm would witness the entire NP class being subexponential?

LPisGood··on Three new discoveries in mathematics, computer science, and physics
I said the same thing in another thread and someone compared it to no one forcing you to own a smart phone. I will preempt that argument by saying the community is motivated to verify these results because they are important to the field.

It is the canonical NP complete problem.
LPisGood··on Anthropic S-1
Actually we can do classical theory of strategic interaction here. There will be a range of acceptable negotiated settlements to both parties since both parties have some estimate E of the expected balance of power resulting after a war. If A is the amount of surplus value Anthropic expects to lose in a war and H is expected amount of value humanity expects to lose in a war, the the range [max(E - H, E - A), min (E + H, E + A)] gives a whole continuum of mutually acceptable settlements.

Now there will be bargaining friction given that any power sharing agreement with Anthropic will likely increase their future capacity and thus the future expected balance of power, but maybe AI has a long enough utility horizon that we should all expect to be dead by the time it realizes the long-term expectation advantage

LPisGood··on AI use leads UC Berkeley math professor to see 'no point' in grading homework
That doesn’t make any sense to me. Access to AI doesn’t make you more credible. At best, it makes you more productive.
LPisGood··on America has lost 200k of jobs in media, film and the arts. How much is AI?
I feel like this comment contrasted with the incredible movie releases this since ~May is just not holding water.

> If a firm spends $99k on compute to replace a $100k engineer and produces 5x the output, how is that not a 5x increase in aggregate labor productivity?

It sounds like they spent 99k to replace 5 100k engineers, which means they could charge 499k for it.

> and getting actionable BI from it.

I’ve always had doubts about the validity of this “actionable BI,” even before it was slop, serving, mostly to serve leadership’s biases and justify their preferred ideas.

If accuracy was never that valuable to begin with then this should not be a problem.

People could point their AI at a physics textbook and ask it to deduce the vuln from first principles too but that doesn’t mean it will be successful.

Certainly! Probability 0 does not mean impossible.

In addition to all of their open source contributions, their ability to pay a ton of money and fun problems to solve led a lot of fantastic engineers to want to work there — especially before 2015.
LPisGood··on DeepInfer: High-performance inference framework for DeepSeek models
If you view creating programs like an optimization problem over the feasible region of valid programs, this is not unreasonable.

A commodity is an undifferentiated good. I expect gasoline to be practically the same at each provider. AI will be similar.

I’m not sure if this counts as a nitpick, but the definition of frontier automatically includes the cheapest models

That is a very interesting idea that I have never heard anyone say. It would certainly help from a liability standpoint I assume.

Is open data just not possible because it is almost all copyright infringement? I wonder why Chinese labs haven’t dumped it at least.

Half a million dollars is a rounding error to the defense industry. If the risks were evaluated to be a national security problem, it would be trivial to do.
LPisGood··on Ask HN: How to deal with shipping AI-written code you don't understand?

Any quality CS program will have you do that for a year or so, plus theory.

The minimum is achieved at a vertex, it is just also achieved elsewhere!
LPisGood··on Interactive Linear Programming in the Browser
A linear program is a fundamental type of constrained optimization problem. It is made of two things: linear inequalities and a linear objective function.

The linear inequalities are referred to as the constraints and the set of points which simultaneously obey all inequalities is called the feasible region. The goal of the game is to find a point in the feasible region which minimizes the linear objective function. That means when you plug the coordinates of that point into the linear objective, you get the smallest value of any point in the feasible region.

A fun fact which is not so difficult to prove in 2 dimensions is that if a linear program has an optimal point (guaranteed when the constraints define a convex polytope), then the minimum objective value will be achieved at one of the vertices of the polytope.

This website lets you change the shape of the feasible region and the direction of the objective function (it is a linear function, so it’s behavior for optimization purposes is fully defined by that direction vector). It then gives you multiple famous algorithms for solving the linear program:

Simplex, for example starts at an exterior point and moves toward optimality. Dual simplex will start at a point with optimal objective and move towards feasibility, etc.

This is very cool. I wish there was a little more information while running each algorithm. Saying the update rule and being able to tick “next iteration” or something would be interesting.
