I believe the SVG file has a transparent background, but the img tag has style="background-color:white". Some browsers honor the background-color setting and show a white background behind the equations, even in dark mode. Some do not, and so the equations appear as black-on-black.
It would be better if I altered the SVG image itself to set the background color, but I don't know how to do that. Suggestions are welcome.
I don’t have a reference, but I believe I read an article explaining that this theory was based on selective data and that in fact dogs have no direction preference.
The title doesn’t give a hint of what the problem is or why it’s annoying, but it’s an interesting problem: how efficiently can you determine whether two finite groups are isomorphic. It’s annoying because it seems it should be easier than it is, given that you have so much structure to work with.
Agreed. Say he introduced 100 bits of notation, 3 good and 97 bad. The net result is that the world absorbed 3 good ideas, and the rest have vanished from memory. Not a bad track record. I hope to give the world three good ideas.
Besides notation, APL introduced some ideas about vector computing that have been adopted in languages like R and Python (NumPy).
Nobody would take a p-value of 0.38 as evidence. There are a lot of problems with p-values in general, but even uncritical fans of p-values would ignore any study with p = 0.38.
I thought there was a difference between a C and C++ implementation, but it was an error on my part. When I fixed the bug, I changed the post title. But the post hit HN while I was in the process of fixing it.
Here's an example. It's not mentioned in the OP, but in a link in the OP. Microsoft's LINQ was designed using principles from category theory. They didn't use category terminology in the final product, and rightfully so.
