And here I thought FB was going to try a more open approach than OpenAI. Silly me.
the88doctor··on ChatGPT Plugins
Long term, you're right. But if you approach the ChatGPT plugin opportunity as an inherently time-limited opportunity (like arbitrage in finance), then you you can still make some short-term money and learn about AI in the process. Not a bad route for aspiring entrepreneurs who are currently in college or are looking for a side gig business experiment.

And who knows. If a plugin is successful enough, you might even swap out the OpenAI backend for an open source alternative before OpenAI clones you.

the88doctor··on Surprise computer science proof in combinatorics
Some number theory results about sequences and progressions can be applied to create more efficient algorithms to approximate the solutions to multi-dimensional integrals that come up in physics (especially solid state physics on lattices).

Solid state physics problems of that sort are used in the process of engineering new materials (e.g. a more efficient dielectric for capacitors, a magnetic material that can store magnetic memory data at higher temperatures without destablizing, a higher temperature superconductor, etc). Idk if this particular result has such an application, but I wouldn't be surprised if it did.

In addition to solid state physics, "special functions" show up in many areas of applied math and physics, including the design, calibration, and data analysis of/from MRI machines and antennas. Many special functions including the hypergeometric functions can be approximated more efficiently using fancy number theory algorithms.

There is also a broad category of physics and chemistry problems that are best solved by Monte Carlo simulations, and sometimes Monte Carlo approximations can be made using many fewer iterations by choosing a set of points within the sample space that satisfy number theoretic constraints.

Also, physics models often inspire machine learning models so it's not impossible that some niche ML algorithm could eventually benefit from a faster algorithm that uses this result or a derivative of it.

None of these directly answer your question about a definitive application for this particular number theory result, but I hope it gives you an idea of what it could potentially be used for. The closest analogy I know if is that certain multi-dimensional Monte Carlo integral approximations can be done orders of magnitude more quickly if you choose lattice points whose coordinates satisfy some similar-ish constraints to the ones described for this problem.

the88doctor··on Ask HN: Get a job or double down on my own business?
It's impossible to give you any useful advice without knowing more about your situation. What type of business do you have? Does the "impact" of the economy on your business mean a 5% hit to profit or a 50% hit? How much of a hit could your annual profit take and for how many years before you wouldn't be able to keep paying for your lifestyle? What are your skills / what kind of job role would you potentially qualify for? The answer to each of those questions will have a significant impact on what your best course of future action is.

Even if SVB maintains their deposits, that IS a liquidity issue, it just isn't a solvency issue.
the88doctor··on How much of AI's recent success is due to the Forer Effect?
I've asked chatgpt to write several poems and songs, and there are definitely a lot of general lines included. However, the content of those poems and songs is not what's most interesting to me. What's more interesting is that chatgpt can produce coherent rhymes, reproduce the 'style' of Eminem, or stick to the rigid structure of a haiku while giving even general lines. That's honestly still better than most people who write poems or songs can do. Also, if we move away from artistic content generation and into code generation, then it's harder to say that working code is just a Forer statement.
the88doctor··on The economics of stadium names
That sounds plausible, but the data still suggests doing broad-based advertising through stadium names probably won't give you the ROI you're looking for.
the88doctor··on The economics of stadium names
Typically stadium name deals prohibit any reselling or sublicensing of the naming rights because the Team want's to control what companies they are associated with.
the88doctor··on The economics of stadium names
My original article actually included an entire section on how to measure the effectiveness of stadium advertising, but I ended up cutting it due to length.

Essentially, you can try to break down the benefits into more understandable pieces. E.g. seconds of stadium dome signage shown on TV, seconds of press conference backdrop with stadium name shown on TV, number of eyeballs passing a sign during a game (classic billboard problem), etc.

If you run through these estimates (which clearly not all companies do before buying), it almost always looks like a bad deal. The stock ROI analysis confirms this, and is also a bit more compelling imo because it's harder to argue that something was left out. However, there are exceptions (such as Target) where the advertising components of a stadium deal can actually appear to be quite favorable, and interestingly the stock performance backs that exception up. My next Market Intelligence newsletter mentioned at the end of the article will go into more detail on how to do that analysis for an arbitrary deal.

the88doctor··on The economics of stadium names
As a couple others have mentioned, this is a different analysis, but the answer is that generally localities that subsidize stadiums do not see a good ROI. Local residents typically end up paying the bill through e.g. a slightly higher sales tax. Corollary: If you want to pay less local taxes, don't live in a city that has a major league sports team.
the88doctor··on The economics of stadium names
Staples is a great example to study. Also Sports Authority, PSINet, Enron -- there are many fascinating case studies. The article would be way too long if I included all of them though. However, the upcoming Market Intelligence newsletter issue I mention at the end of the article will go into more detail on certain examples via the lens of a checklist that anyone running, advising, or investing in a company can use to vet a particular naming rights deal.
