I found this blog time ago in Google, searching with terms "mathematics for programmers" I arrived to the article : Why there is no Hitchhiker’s Guide to Mathematics for Programmers http://jeremykun.com/2013/02/08/why-there-is-no-hitchhikers-.... Which I'd recommend to read as entry point to this website if you feel intimidated by maths. Nice to find it again :)

I know it's a HN cliche to complain about form over the message, but I find this impossible to read without first removing the entire left-hand panels (and ::before p-elements) which re-grab my eye every line-break.

> A consequence is that, if you’re trying to cluster data points by looking at points within a fixed distance r of one point, you’ll have to make r exponentially large in the dimension.

That does not follow ...

but it looks sorta mathy, I better upvote even if the guy has no clue whatsoever!

If you use safari or firefox, reader view is available for the articles.

His point is the volume of the unit sphere is tiny. The "volume" of the unit 20-cube is 1. The volume of a 20-sphere is just 0.0258. 100-cube, volume is 1. 100-sphere, 2.36e-40

If your algorithm works well for "nearby" meaning 1, i can just keep adding dimensions till you find nothing. If "nearby" on the other hand is related to the number of dimensions, you're going to have to grow the "nearby" value exponentially.

I just zoomed in until the left-hand panel disappeared. Annoying, but the font is too small anyway.

I'd like to find a way to reorganize Math ∩ Programming eventually. As alfonsodev points out, it's a bit hard to find stuff for newer and less mathy readers, though there is a handful of articles aimed at them. [1,2,3,4] As other users point out, they don't like the layout. Suggestions?

edit: updated font size & article width. I'm considering changing the theme completely.
