Fibers

Fibers are an abstraction over sequential computation, similar to threads but at a higher level. There are two ways to think about this model: by example, and abstractly from first principles. We'll start with the example.

(credit here is very much due to Fabio Labella, who's incredible Scala World talk describes these ideas far better than I can)

Callback Sequentialization

Consider the following three functions

import os
import sys
import argparse
from glob import glob
from itertools import chain

import fontforge

ADDITIONAL_LIGATURES = [
    'x.multiply',

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.

You can import data as follows:

# Import a JSON document into table `users` in database `my_db`
$ rethinkdb import -c HOST:PORT -f user_data.json --table my_db.users

# Import a CSV document
$ rethinkdb import -c HOST:PORT -f user_data.csv --format csv --table my_db.users
