Subsetting an array involves allocating a new array and copying over each item to the resulting array! I had no idea how costly this action was. :0

Amazon owns Twitch, and every object in the universe greater than 0 Kelvin emits electromagnetic radiation.
Amazon owns the Washington Post. I also learned about the prominence of "Snow Fall" by the New York Times, which shook the world of journalism when it was published in 2012.
406 is the area code for the ENTIRE state of Montana.
While analyzing Today You, Tomorrow Me for an essay about scrollytelling and data-driven journalism, I learned that Louisiana is divided into parishes and Alaska is divided into boroughs the way that the 48 other states are split into counties.
While doing readings for a class about startup funding, I learned that most Fortune 500 corporations are registed in Delaware because of the "bi-partisan political consensus in Delaware to keep the Delaware corporation statute... up-to-date" and its special court, the Court of Chancery, which is highly respected in legal culture and keeps corporate law disputes from "[getting] stuck on dockets behind the multitude of non-corporate cases."

From this Udemy course about NodeJS, I learned that one can add functionality to JavaScript by embedding a JS engine (e.g. V8) in C++ code.
I learned how to walk from Building 9 to Building 38 at MIT without going outside.
I learned that you can access Facebook Messenger on messenger.com. I've just been going through Facebook every time.
I sort of learned how an ink-jet printer works by doing my physics problem set. "An ink jet printer sends charged ink droplets through an electric field that accelerates the charges. The curved path of the charge is easy to calculate and controls where the ink droplet strikes the paper." The majority of droplets are actually recycled, not used to print.
I learned that in Australia, you get fined for not voting.
Shayna informed me that sugar is made from evaporated sugar cane juice.
I learned what `use strict` actually means.
I learned a lot about Mapbox GL JS as I prototyped a project, including how datasets, tilesets, and styles relate to each other. I also learned about wind roses, a type of graph that's useful for showing how wind speed and direction are distributed.
I made an omelette for the first time!
I learned that the lyrics to "Skin" by Mac Miller go "My dick on business trips" and NOT "my dick on Dennis strips."
I was wandering through Target and got curious about how scratch-and-sniff works, so I asked Siri and learned that molecules that produce a smell are encapsulated in micron-sized gelatin or plastic spheres. When you scratch the material, you break some of them, releasing the smell. (from HowStuffWorks)
Today I learned that Tom Preston-Werner made Jekyll. I was shook, but in hindsight, that makes a lot of sense.
A nice quote I came across today: "How can we possibly justify — to our employees, to our investors, to our spouses, to our friends, to our fellow citizens, or to ourselves — learning slowly, by experience or trial and error, what we can easily pick up in a book?" —Ryan Holiday
I asked Linus about how to learn what people are looking for through a conversation, and how one can help them if they're just a student. His hunch is that people usually have something they really want to do but don't have time for, or a topic they could gush about for hours but rarely get the chance to rant about.
To get to that interesting discussion, ask "why" about decisions they mention. If they recently moved or accepted a job offer, what led them to do that? It's a bit hard to add value in its usual connotation, but sometimes people just want someone thoughtful to bounce ideas off of, or give recommendations on what to check out in a new city.
I was watching lecture videos for 6.0001 (Intro to Python/Programming) since I'm planning to test out of the course next month, and I learned about different approaches to testing: black box (independent of implementation, exploring paths through the specification) and glass box (exploring paths through code; tests are path-complete if every potential path through the code is tested at least once—it can still miss bugs in boundary cases, though!).
I completed my training as a new Bluebonnet Data Fellow and learned a bit about the goals of political campaigns, what tools they use, and how data can inform their decisions. I also learned about software versioning conventions while making an archive of Science and Us's website iterations (which loosely follows conventions).
I learned about the concept of a "highlight" for your day. Neither lofty, long-term goals nor detailed daily to do lists are satisfying, so the authors of Make Time suggest picking a highlight—a focal point—for each day. Highlights take around 60-90 minutes, and by focusing on them, you shape a more positive perception of your day.
While taking my physics final I learned that I should've tried more to stimulate test conditions while studying 😅 I had a decent understanding of how to solve problems conceptually, but not enough practice catching my mistakes in computation/execution.
I love Upstatement's work, so I was on their website, noting specific features and design choices I liked. In doing this research, I stumbled across the Interaction Observer API.
While taking down the set for this semester's Asian Dance Team showcases, I learned that some cables have five pins (instead of the standard three).
