It looks like transform(tree.left) returns an Option[Tree] already (otherwise the code would not type check) so the entire if-else in the original code seems redundant and could be replaced with:

    val transformedLeft = transform(tree.left)

My 6yo daughter has exceptional talent and interest for Math. She's already discovering some fundamental theorems for herself (number theory, algebra, geometry). Does anyone here know any resources to help her development?

I think he meant "despite not having L3"

Killing all slaves in the ship?

Maybe they developed the photos in open air at night?

John Holer died in 2018

Anything is safer than to run C code directly ;)

It's right there, in front of them, all the time

But what if one doesn't remember the `apropos` command?

With all due respect, you are just trying really hard to be pedantic. Your convoluted, contorted, corner-case example does not invalidate anything that was said here. You even had to resort to the word "rounded" to make it work. Without "rounded", most would be below mean.

GP comment did not imply that half of elements are below average. It just said that _some_ have to be. By definition, we cannot have all elements be above average: at least one has to be below.

Not everyone is traveling to the beach on vacation. There are numerous valid, serious reasons people need to travel.

I created a similar REPL presentation tool for Scala: https://github.com/marconilanna/REPLesent

The banana is not just a background image, it is a set itself.

You have to raise the price by 43%: 1.43 * 0.7 = 1.00

> When they did the hardware transitions, they had a compatibility layer (Rosetta) that was supported for 5 years after the transition. But with the 32 bit change, the announced that it would no longer be supported in 2017, and dropped support in 2019, just 2 years later.

You are comparing the time a technology was supported with the time it was announced a technology would no longer be supported. 32-bit apps were supported in 64-bit Mac OS systems for at least 7 years.

Shameless plug, and a little tangential to your question, but I created an interactive training/presentation tool based on the Scala REPL: https://github.com/marconilanna/REPLesent

I believed someone created a Python port inspired by it.

There is PMD's CPD: https://pmd.github.io/latest/pmd_userdocs_cpd.html

I have a 6 yo girl that is very Math oriented, and she always loved playing with magnet building tiles:

Just make the smallest possible fractional cent the unit then

"Odd" is just a word that means "not divisible by two". There is truly nothing special about a prime not being divisible by two. I could equally say "3 is a legendary prime god amongst countably infinite non-divisible-by-three primes", "5 is a legendary prime god amongst countably infinite non-divisible-by-five primes"... The only difference is that we do not have special words that mean non-divisible-by-three, non-divisible-by-five, etc.

In this regard, I don't see 2 as a special prime. Saying "2 is the only even prime" is the same as saying "2 is the only prime divisible by two", which, by definition, can be said about any other prime.

Why do you think 2 is alien? How could the fundamental theorem of arithmetic be stated without 2?

> Black holes have the same gravitational effects as any other equal mass in their place. They will draw objects nearby towards them, just as any other planetary body does, except at very close distances to the black hole. If, for example, the Sun were replaced by a black hole of equal mass, the orbits of the planets would be essentially unaffected. A black hole can act like a "cosmic vacuum cleaner" and pull a substantial inflow of matter, but only if the star from which it formed was already having a similar effect on surrounding matter.

I don't think anyone can beat Dennis Ritchie on the "designed languages on which trillions of dollars of commerce depend" metric, especially when we consider the many languages which are themselves implemented in C.

Knuth is 80 and has been programming since at least the late 50s: https://en.wikipedia.org/wiki/Donald_Knuth#Education

Are you truly suggesting we allow young, healthy individuals to die in car accidents to harvest their organs?

You should be asking yourself what will happen to the average lifespan of those who won't die prematurely in a car accident.

Someone should write "Scala features I miss most in Kotlin"

> I think the problem is people who feel they have to use the latest and greatest feature and they have to know all the frameworks.

The problem is the marketplace and the companies that will demand the skills when one is job searching.
