Nevertheless, it seems quite obvious the author did not literally interpret the eigenvector as "x% of future projects will be written in Go." Rather, the conclusions he drew were along the lines of "Oh wow look Go is on top,

I interned at LLNL and went to a few talks where they discussed small-scale physics first-principles about how the interior of a star works, and I was shocked to discover that these videos were basically all that they had to go off. (And NI

I didn't interpret the results in this post as "predicting the future distribution of language use." Rather, I interpreted the ranking as an indicator of a qualitative trend in that distribution. I think the author also made

In an unrelated note: interested in doing a guest post over at Math ∩ Programming? I see you've got lots of cool stuff with high-dimensional NN :)

Power method is not matrix-matrix multiplication (which is not N^3, BTW [1]), but rather matrix-vector multiplication. So the power method is N^2*k where k is the number of iterations required to reach precision (usually polylogarithmic). A

The thing I like most about this post is that it's falsifiable. We will know in ten years whether C and Java are still popular, and whether Go succeeds in the sense this data suggests. So thank you for being concrete and clear, even if

Doesn't it make sense if you ask: Given that someone will change the language they're using (and writes a public blog post about it), which are they most likely to change to? It's not unreasonable to use that as a proxy for i

I think you have to ask why mathematicians make that tradeoff. I argue it's for a good reason: the long-term efficiency gains for a working mathematician are higher than if they spelled everything out all the time. I'm using a mad

Problem is you can't efficiently do everything math needs to do if you write out everything like that. Notation is designed for the efficiency of reasoning after you've fully absorbed the ideas being expressed.

For bandit learning MWUA is called EXP3, and it's close to optimal (off from the information-theoretical lower bound by a factor of log n, I believe). Various improvements like EXP4 and EXP4p keep improving this bound. The difference i

Having a set of concrete examples in mathematics is like unit testing in software. The second you get stuck on a theorem, you fall back on your examples. The second you run out of examples that explain a behavior or new theorem, you write d

> it's "impossible to know anything for certain" is lost on people In my experience, people tend to use this phrase as a bludgeon to exclude ideas they don't like. It's a way to stop a discussion, not help promot

I suggested nothing of the sort. I am criticizing your use of "still going strong" as proof of good design. And there are many possible explanations of why Apple adopted Unix. Inertia is certainly one of them! (If you want to writ

Inertia is only proof of inertia.

What is your opinion on publishing a math-heavy e-book (like, equations on every page, inline and offset)? I don't think I will be able to do better than having a physical book paired with a pay-to-download PDF.

I am using LaTeX, but I'm almost certain it will be a pain when I go to the eBook step, since they all have their own formats and I'm not aware of any tools that can render the math formulas in my book faithfully on all of them.

Actually, you misread my comment: if someone disagrees with my ideas on gender inequality, I will only take them seriously if their reasons include evidence and logical reasoning. It doesn't take much, either. I've heard people te
