Dude you went to MIT? That's rad. EDIT: why downvote someone for complimenting them on their top schooling?

The concept of references was introduced in my introduction to Java course I guess at the same time that the concept of objects were explained more fully. At least in Java, I feel that you have to understand the concept of references, to be

Maybe he means more like "four cores is as good as it gets" (for certain domains). We can always want things to get harder, faster, stronger , but delivering on that is another matter.

I don't get what a Rust GUI would give you, in this case?

Doesn't OCaml have bad support for concurrency, though? Concurrency is one of the features that people who look into Go are often after.

I was at a lecture about security in C/++ code a couple of weeks ago. His conclusion was basically: > There are no silver bullets with regards to safety in C/++ code; in order to achieve security, the programmer has to pay the

With that in mind, I tried to use the phrase in a more wide sense than some other language communities would. But you're right that that phrase might as well be disassociated with the language at this point, to avoid confusion. Better

I don't really see it - a language made for systems programming (read: non-application development) being used for developing Android apps? Or is there some other kind of Android development in mind, here?

Java and JS have both been at the butt end of many a joke, probably including satire.

Can't I just take your glib statement and just reverse the roles (JS developer not understanding Java)? What makes JS development more misunderstood than Java development?

"Result" is a pretty opaque name: any value or type can be called a "Result", really. "Either" at least hints to the fact that it is either-this-or-that. "Either" is IMO a nice counterpart to tuple ty

That doesn't seem nice if the map wasn't supposed to be nil (if you assume that failing fast on buggy behaviour is good). But I guess you might want to, on purpose, instantiate and use a map which is nil?

I think there is a difference, and for the worse: `0` is a perfectly valid integer value which can be used like any other value. `null` is a valid reference value, but is invalid as far as dereferencing goes; refer NullPointerException. `0`
