CSV are nice for data interchange or even for storage if compressed (storage is interchange between the past and the future). But the very first thing one should do when working with CSV data is convert it to a binary representation. It wil

I'm not thinking just about AD. I would love lots and lots of little simulation modules instead of monolithic solutions. Now some uninteresting story: the reason to have a look at MuJoCo is personal: I studied Mechanics I, II and Analy

I find amusing the fractal nature of the universe: we say that some problems are complex (i.e NP-Hard) because no matter the algorithm you design I can devise a problem instance that will take exponential time for your algorithm (informal e

Julia is the Haskell of numerical computing. It seems like AD is a solved problem, which is not. I can personally think two instances in which I have hand rolled my own gradients: in the context of recommender systems (dense matrices are ev

In any complex field, say data science or software development, any newcomer perceives the solutions to problems they still don't have as unnecessary complexity. So for example the whole idea of dependency management, environments or v

> Numpy is just wrappers for BLAS and LAPACK. Certainly not. I encourage you to have a look at the API of BLAS/LAPACK to perform basic operationa. And that just scratches the surface.

I think the main problem with LP is philosophical: it is used so you can deeply understand the whole program but most people want to understand a part and ignore the rest. So for example extracting how Tex renders math equations is almost i

It requires a lot of skill to write TeX, but the key is declaring it feature frozen for almost 40 years. I like Knuth's approach to open source: "Here is the code, I wrote it because I needed it, I hope you find it useful. Now, if

Is there so much demand in the US that it will impact global wages? I'm not sure. As a foreigner is not in my interest but I do wonder if, just for the sake of coherence, shouldn't the import of labor be taxated in the same way go

They play a role in a different sense: if you see a rifle it may be there because it's going to be fired or maybe because the character likes rifles. Could you imagine The Big Lebowski without bowling? And yet bowling has nothing to do

Quite dull. That's why I love The Big Lewobski. It's full of irrelevant details. There is a story too but the movie it's about the little things.

Very nice. I have somewhere the book Airship Technology, which I bought when I was curious about the possibility of blimp drones (I was an aerospace engineer some time ago). I'm glad you are considering smaller blimps, I think previous

Python definitely started with very good ideas and whatever success it has achieved is by merit and not marketing power or reputation of a company behind. Clean syntax, a decent object model, good documentation. Good taste in general. But i

I'm extremely happy with Julia performance. I'm using it right now to prototype some new algorithms for my PhD. How fast is fast? Well in my case I'm trying to come up with things related to collision detection and I'm g

I once used clang to extract all input/output structures of a big C project. In my case was about generating tests. It's very satisfactory when the computer saves you so much time.
