Hmm. I usually think of "imperative" as "as opposed to declarative", and sequential ordering is one of its hallmarks in that context. And for Clojure atoms specifically I think of "functional" as in Okasaki&#x2

Nope. The sequence of statements in the (let) block is imperative. Atoms are actually an example of how the values of references are updated functionally. Clojure has facilities for both imperative and functional style.

It's not difficult to write imperative code in Clojure; [1] is an example. Immutability-by-default makes you work to mutate things, for sure, but that in itself doesn't make the language inherently functional. [1] https:/&#x

> in 2007, immutability on the JVM was a competitive value prop, but in 2021+ it is nothing special Can you elaborate on this? What do you think has changed in that time to make it "nothing special"?

I worked with some vim power-users (I was definitely not one myself), and learned a lot from them by accommodating their preference. Similar results for other tools that I might not have picked up on my own. The only thing I drew the line a

In 2008, I ran across DHH in an Apple store in Chicago, and got to thank him in person for Rails. Similar story for Matz and Ruby in 2013. My current work is mostly Java, which is tolerable since Java 7/8, but I always enjoy revisiting

I’ve found value in knowing both. And I’ve decided that I prefer Emacs because the mode I care about most —- which I informally call “just type stuff mode” —- is the default “mode” in Emacs.

I find that the editors I use most —- TextMate and the JetBrains suite —- also have the option to use Emacs bindings. I try to maintain functional literacy with vi(m), because it tends to be more available by default, but I’ll use Emacs whe

Part of the communication problem is that “high”, “performance”, and “needs” are all relative, which makes the combined phrase super-ambiguous. If you reach for a thing that’s advertised as “2x faster” because it means you’ll get your answe

Sounds like a broken hiring process right there. Anything you care to share about why that didn't work out? I can't imagine a company having an opportunity to hire you and choosing not to.

“exuberant”? I think “exorbitant” makes more sense in this context. Edit: Unless you were really really happy about what you paid, I guess.
