OOP as used in R is very much a function of API design and not a function of routine R usage for data analysis. To many users of R they are not even aware that they are using OOP at all, especially for the S3 style of objects. When you have

I feel like this is drifting away from the point. Eugenics was a scientific movement with the aim of producing better humans through selective breeding and especially through involuntary culling and sterilization of humans with undesirable

Mods: Can we rename the title to "more transmissive than glass", even if that is not the underlying title? Half of the commentary here is focusing on that detail and it detracts from the discussion.

The article suffers from skipping between layers of abstraction in an attempt to make a point, and in the end in doing so fails to make the initial point. In the first "Myth" section, that "nobody understands this quantum stu

I think more than splitting hairs. Eugenics is not just the application of selective breeding to humans. We've been doing selective breeding since the dimmest reaches of history. Eugenics arose at the convergence of evolutionary theory

There is no conundrum -- eugenics is wrong not because it is immoral, but also because it is fundamentally an incorrect theory and results from a misunderstanding of how evolution works. The idea of eugenics is to use selective pressures to

Depending on the type of string search this is not completely true. A naive string search is O(kn) (where k is the length of the search string) which is actually slower than the O(n) that a DFA can get. But KMP and similar algorithms can do

And the converse as well -- an algorithm that is 10,000,000 * n^17 is going to be effectively intractable but falls neatly into P. And the reality is that most NP-complete problems are well-solved by heuristics except in strange combinatori

That's true and easy to forget -- at the time, YouTube offered far and above the best experience for content creators and uploaders. And their end-user experience (the flash-based player) was miles ahead of the competition.

I can't find the second two; the first one [1] is simply inconclusive; small sample sizes but no real effect. Crucially, this one compares duct tape to placebo (a corn pad, which seems to be a foam ring that surrounds but does not cove

It's fairly straightforward -- use your fountain of money from search ads plus a huge infrastructure to support it to pay the costs rather than pass them on to users. Operate at a loss to drive out all competition and prevent new compe

Did you document your failure? I'm honestly curious -- the author of the post mentions some of their false starts, but I think a description of what you tried and what didn't work could be valuable (even if you didn't do an e

This was posted before ages ago, and I suspect I know the answer, but I have to ask -- has anyone here successfully done this? I had grand designs to use ethanol as an anti-solvent to accelerate crystal growth, and I bet you can guess how m

Tangential to your point about the poor phrasing is that having "infinite ... numbers between just 0 and 1" is not evidence of a higher infinity. Specifically, there are infinite rational numbers between 0 and 1, but rationals hav

If you're looking to run some numerical experiments with this, there is built-in support in R for this sort of thing: plot(polyroot(runif(101,-1,1))) will give you a visualization of the roots of a polynomial of degree 100.

Just to nitpick, while commonly accepted, the idea that CO2 increase is anthropogenic is routinely disputed by climate skeptics [1]. The argument generally is that warming temperatures cause rising CO2. This in turn is a fact not disputed b
