    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.

    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 w…

    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] [1]: https://davidlowryduda.com/mathshare/

    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.

    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 i…

    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:…

    I've never seen this before. But yes, this does work. And that's very nice. Thank you for the tip.

    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 …

    I'm confronted with a similar problem frequently. I have a growing bash script and it's slowly growing in complexity. Once bash scripts become sufficiently long, I find editing the…
