Would someone be interested in explaining what in the world is going on in that article?

This is true in my case! I've had more people actually buy me a coffee after interacting with my site than to click on my Buy Me a Coffee button.

I find a link to "Buy me a Coffee" to not at all look like an ad. It's a funny-shaped "donate" button. And I much prefer it to actual ads.

I wasn't aware that there were any public, commonly-used voting machines that we could check.

I was very surprised to see that the article explicitly says it will not consider this answer!

Are there leaderboards that you follow or trust?

Also, do you have preferred OCR models in your experience? I've had some success with dots.OCR, but I'm only beginning to need to work with OCR.

How does this relate to the mean entropy of 1 noted in the OP article?

I wrote a similar app when mathbin was shutting down. It allows about 1500 characters of mathjax-displayed notes. [1]

I'm not very familiar with proper exception usage in C++. Would you mind expanding a bit on this comment and describing the misunderstanding?

That seemed to me like a radically high estimate of people who use ad blockers. But I see that the first page of results on MyFavoriteWebSearchEngine support that claim.

New comment by mixedmath in "Leaving Gmail for Mailbox.org"

Interestingly, one of my biggest problems with Gmail is that they don't allow actual plaintext. I used to routinely collaborate with developers who were vision-impaired, and the official Gmail phone app wouldn't let me send them plaintext email. Instead, it was some sort of HTML thing. Unfortunately, we sometimes sent code snippets to each other over email, and though admittedly it looked more or less fine, Gmail changed the underlying representation enough that my collaborators' screen readers would mess up on the parsing.

This led to me leaving Gmail on my phone, which led ultimately to me leaving Gmail entirely.

New comment by mixedmath in "AI for Scientific Search"

mixedmath — Mon, 07 Jul 2025 14:24:00 +0000

Google is completely inadequate at mathematical search. But here is a concrete problem that no search seems to handle: given some complicated integral (say, some contour integral involving a K-Bessel function), find where it appears in the literature.

Most search will totally fail, because this is made of math symbols. Embedding-based search will give various related things involving, say, integrals and Bessel functions. But then I end up opening Gradshteyn and Ryzhik and trying to find where in this book the relevant terrible integrals appear.

This is a common experience for analytic number theorists. And it's a lousy experience.

From the title, I had thought that this would be a new tool for searching science, such as searching the arxiv. But this is actually a survey.

I quote the conclusion of the survey:

---

In conclusion, rapid advancements in artificial intelligence, particularly large language models like OpenAI-o1 and DeepSeek-R1, have demonstrated substantial potential in areas such as logical reasoning and experimental coding. These developments have sparked increasing interest in applying AI to scientific research. However, despite the growing potential of AI in this domain, there is a lack of comprehensive surveys that consolidate current knowledge, hindering further progress. This paper addresses this gap by providing a detailed survey and unified framework for AI4Research. Our contributions include a systematic taxonomy for classifying AI4Research tasks, identification of key research gaps and future directions, and a compilation of open-source resources to support the community. We believe this work will enhance our understanding of AI’s role in research and serve as a catalyst for future advancements in the field.

I jumped at this because I'm a mathematician who has been complaining about the lack of effective mathematical search for several years.

I've never seen this before. But yes, this does work. And that's very nice.

Thank you for the tip.

Do you use maxima? Would you say it's still worth using and learning?

This will not be taught in textbooks. Wildberger works in a math world where "infinity" or even "really really big numbers" don't exist. There is nothing mathematically wrong about that world, but others (like me) do not find this problem context to be a useful framework to work in.

I haven't read anything from the London Review of Books before. But this seems excellent. Is this indicative of their general quality?

New comment by mixedmath in "Trees not profits: we're giving up our right to ever sell Ecosia (2018)"

mixedmath — Mon, 10 Mar 2025 12:11:07 +0000

I've been using it as my primary search engine for a couple of months. It's not great as a search engine. I find their locality of search to not be well-supported (e.g. the search "food near me" works good in google and not great in ecosia).

Ecosia doesn't emphasize recent events, news, or posts in search results as much as I'm used to --- but I haven't decided if this is good or bad.

It's not so bad that I've changed. But I do sometimes use a better search engine when I want better results.
