I've used zippers to edit parse trees. Very useful API, if a little user unfriendly.

Having moved into a home previously owned by a chain smoker ten years prior, I have no problem believing this. We've had to run ozonators in rooms repeatedly to finally get the smell out.

Vernor Vinge had it figured out in A Deepness in the Sky with the use of kiloseconds, megaseconds, and gigaseconds.

It's certainly been a massive financial hit to the greater Baltimore area, so that sounds appropriate. Insurance companies need to account for large shocks -- it's the whole reason their industry exists.

In what way have the TensorFlow or Cassandra teams adopted Clojure? They both have third-party Clojure clients, but neither appears to be using Clojure for their project's implementation.

Any good resources on how to use flakes? I'm currently experimenting with having home-manager work via a flake but I haven't come across any good HOWTOs on common operations. For example, I'd like to update the flake dependencies similar to how I used to use "nix-channel --update" to freshen the dependencies used by home-manager.

We did, however, have the capability to implement walkable cities with decent public transport. Not every city had to have an interstate running down the middle of it.

I think a lot of their products are only held together by the hopes and dreams of their sales department.

Let Over Lambda by Doug Hoyte was a compelling read for me, even though I don't work in Common Lisp that often. It's a very opinionated work that flies in the face of a lot of conventional Lisp practices (he loves his macros!) I don't necessarily agree with everything written, but having to think about why I didn't agree in itself made it a value-add to my book collection.

I hope that they adopt something along the lines of the Gumshoe RPG System that provides a little more depth to the investigative aspects. Blade Runner shouldn't be just a combat-based shoot 'em up; it demands attention to its roots in noir detective fiction.

It's Meta's responsibility to justify the existence of their data center. It's not any country's responsibility to host it.

Even with StackOverflow, try finding the current canonical means of building Python applications and deploying artifacts. It's a maelstrom of outdated advice.
