100%! We read to our kids a TON from the day they were born -- no tricks or gimmicks, we just read to them. A lot. And they've always seen us reading actual books. YMMV, but our kids learned to read early and well and they both still enjoy reading. A lot.

Tom Lord has died 4 years ago

I don't doubt or dispute any of your points, but it would have been far nicer to wait and air them at a different time and in a different venue -- step back for now and give people a chance to grieve and pay their respects to someone who just died unexpectedly.

Make a new venv for everything and don’t pollute the global environment and it should be fine.

This just proves the point that Python sucks at managing dependencies, which exacerbates -- perhaps even encourages -- the reproducibility issues being discussed.

Amen!! This is the best way to learn anything technical -- put things into practice to understand the theory. It's also important to keep revisiting the theory to understand results, rather than parroting some catchphrase to "explain" results.

You are of course welcome to your opinions about these things, but please be respectful enough to spell the late David Graeber's name correctly.

In general, filters do what their names suggest -- they filter out noise or unwanted components of signals. The simple Kalman filter filters out white noise to estimate parameters that describe a system; other filters use things like the Fourier or wavelet transform to, say, select certain frequencies and remove others.

Great book! Was on my list for years and I finally read it a year or so ago. Strangely, though, I couldn't get into Fall of Hyperion and set it aside. Perhaps it's time to dust it off and finish that series...

If you want to define the median in a way that generalizes to other situations, this is actually not the way to go! Here's a more general definition: a median of the numbers {x_1, ... x_n} is a number m that minimizes the sum of the absolute deviations, |x_1 - m| + |x_2 - m| + ... + |x_n - m| . Medians are generally not unique via this definition, but they can then be defined for things like sets of points in the plane, in space, etc. (cf. geometric median); the traditional definition is the average of all of the medians under this more general definition.

Pursuing this question is quite the rabbit hole, but doing research in mathematics makes me believe that math is a science: you have questions, you collect evidence by exploring examples (i.e., conducting experiments), and you formulate hypotheses as conjectures. If you're lucky, your conjectures are correct and you prove them! Proofs are even better than the accumulated evidence on which theories in other sciences depend, in that proven theorems are immune to falsifiability within the axiomatic system in use.

Books I Recommend 7 years ago

There ought to be (and probably are!) analogues of StackExchange or MathOverflow where people can post and discuss solutions for problems in specific books. Would be interesting to know about existing options.
