Well, that was unexpected. In the following, I’m trying to follow Jon Evans’ advice from “The Terrible Technical Interview”.

Hi there! Thanks for offering to let me take a HackerRank test for ABC, I appreciate the vote of confidence.
Scaling your API with rate limiters
The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.
In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.
Request rate limiter
This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
What I Wish I'd Known About Equity Before Joining A Unicorn
Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.
This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would
The other day, I was wondering why Clojure fits my brain so well. I think I was relaxing on my old couch, drinking cheap beer, eating a gas station pastry, and drawing doodles on a stack of overdue bills I forgot to pay. Little did I realize, these things are all connected.
I have a hypothesis that people choose programming languages based on their personality. For the purposes of this write-up, I’ll use the well-known distinction between type A and type B people. This may be pop psychology stuff, but it’s convenient for my point so in the spirit of American politics I will treat it as fact.
Type A vs Type B
Type A people are very organized, competitive, punctual, and like to plan ahead. When I was a kid, these were the ones who had perfect grades, competed in track or swimming, and on top of that they were nice people so I couldn't even hate the fuckers. Type B people, on the other hand, are laid back and like to do things spontaneously. Like The Dude from The Big Lebowski, they are comfortable with
React "Hello World" Examples
Below are a small collection of React examples to get anyone started using React. They progress from simpler to more complex/full featured.
They will hopefully get you over the initial learning curve of the hard parts of React (JSX, props vs. state, lifecycle events, etc).
You will want to create an
index.html file and copy/paste the contents of
1-base.html and then create a
scripts.js file and copy/paste the contents of one of the examples into it.
