Then you don't know the difference between Maoism and Leninism. Basically, Maoists can live with any compromise in order to bring forth their communist ideals, even if the compromise is to backstab Soviet Union and open the door to the

I use both pandoc and LaTeX in my day job. I have to disagree somewhat with your first statement. I think it varies by the use cases. I usually start a writing project in pandoc Markdown, until at some point I have many equations, figures,

I'm afraid the case isn't that simple for academic publishing. The authors, i.e., scientists who conducted the research, usually pay a lot of money (typically 1500--2500 USD, depending on the journal) to the journal to get their p

Sure, the author spent a long blog essay and didn't get the point across as clearly as many of the comments here on HN. If this were to be a research paper it would likely get rejected without a review. Not to mention the whole point o

My math is rusty but 1 / 0 := 0 implies that 0 * 0 := 1. This contradicts the definition of a binary field [1], let alone a field of real numbers. [1] https://en.wikipedia.org/wiki/GF(2) > "It is totally f

Even among scientists there are people who don't like 1-indexed arrays (me, one data point)! However, Julia 0.7 and 1.0 have the keyword "begin" so that you can basically program arrays in an index-agnostic way.

And palaeontology. There may be tens of thousand of research papers behind each map shown in the OP. It is like solving a puzzle. At location X, Scientist A finds some clues in plate tectonics, Scientist B finds something in geochemistry, a

Agree. It's a bit surprising to see that numpy indexed operations are even slower than the built-in list in this example. It seems the idiomatic numpy way to perform the iterations is through vectorization, but that often leads to code

Chinese propaganda today still infuses its citizens with a sense that Han Chinese is superior to other ethnic groups and races. You wouldn't possibly find anything remotely like that in any other Asian countries. If you think I'm

Second this. Cython's memory view for numpy array is great.

The text-only website is just perfect to read in the CLI environment using lynx. No ads, no distractions, just the contents. Definitely underrated.

That is because Nature Perspectives are written by real scientists for a wider audience than their niche. Not only are those articles scientifically more accurate, but the writers usually try to engage in a dialogue with the readers, which

For the example teenagers = people.where(lambda p: 20 >= p.age >= 13) I prefer the good ol' Pythonic way teenagers = filter(lambda p: 13 <= p.age <= 20, people) because I know how filter behaves, but am I

On the other hand, global imperialism has always played a role in forging a lingua franca in many ages, just like Classical Greek in the Hellenistic period and Latin in Roman Empire. (Disclaimer: I'm not judging the morality of imperia

I commend you on your courage. Reminds me of one of my good friends from college, who bailed out in the second year of his PhD program in geochemistry and started anew in a MSc program in Computer Science. He now works happily in a startup

Because most modern PhD factories are sweat shops that offer a rather dismal career prospect. (If you've been through the process --- I suspect there are a lot on HN --- you know what I mean.)

That's true. It predated C but even then abstracted the user away from the hardware (and still does). I wouldn't suggest any use of Fortran beyond number crunching and array arithmetic.

by geoalchimista 8y ago
Modern Fortran (90 to 2008) has evolved a lot regarding array arithmetic and broadcasting, yet still maintain backward compatibility. I don't think that couldn't be done in C, but as many has pointed out, the problem seems to be w

Fair enough. I didn't see the last line. I retract what I said earlier. Still I am not very convinced that it is a good idea to teach STEM students that way. The author of the article works at a liberal arts college.

I'd be curious to see what a math prof would have on this. But IMHO, math is learned by writing proofs . That is the only solid way for building an understanding.

Title is clickbait. Whatever you can learn from "drawing, playing with beach balls and knitting" is most likely not advanced math . (Otherwise professors in a math department would all be playing knitting and beach balls to get t

Second this. I remember back when open access or reproducibility was not a thing, I used some little app written in Java to "steal" data from scanned figures of other's papers datum by datum, because they just wouldn't p
