There shouldn't be a difference between Aliasing and cloning for immutable data because you can't change the data. Deep vs shallow operations is an issue in both imperative and functional programming. In python, you have '==&

On the other hand, we have to teach people about aliasing vs cloning in imperative languages. a = [1, 2, 3] b = a b.append(4) assert a == [1,2,3] No matter which paradigm we use, there are going to be hidden traps new p

Because the virus is spreading exponentially, the rankings for per-capita cases/deaths are going to be highly dependent on how long the outbreak has been going on in that area. Is the US's health care system worse than Palestine,

Deaths per capita will be most important at the end of the pandemic. Right now you're better off looking at case-fatality-rate, day over day rate of new cases, and the current number of cases. Right now the US is at 52K cases and ~650

SARS was much more contained, and only infected ~8K people. It infected ~3K people outside of China, most whom were in east Asia. The case counts outside east Asia were in descending order: - Canada: 250 - US: 27 - Germany: 9 Areas affected

The 10K+ deaths is over the entire course of H1N1/09. The US had ~4K deaths from 2009-04 to 2009-10 [1]. Italy has had 3K deaths in just 2020-03 [2]. You can't directly compare the early state of COVID-19 to the end state of H1N1&

Why does the difference cost £1000? The electric assist bike conversion kits I see in the US are $300-500. Are the purpose-built ebikes tons better than the conversion kits?

Personally, my issues with threads and the various locks is that you have to manually manage resource ownership. It's kind of like programming without types, with manual memory management, or with null values. It's easy to program

I'm not sure this is the reason, but function types look better if you put the return type after the parameter types. Compare C to Kotlin: float (* f)(int); val f : (int) -> float; float[] (* map)(int[], float (*)(in
