Mathematics: What do grad students in math do all day?

by Yasha Berchenko-Kogan

A lot of math grad school is reading books and papers and trying to understand what's going on. The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article.

The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter.

What can you say?

# In case anyone is wondering how to easily use the :crypto hash or hmac API's from elixir-land, here you go.

File.stream!(filename, [:read, {:read_ahead, 65535}], 65535)
|> Enum.reduce(:crypto.hash_init(:sha), &:crypto.hash_update(&2, &1))
|> :crypto.hash_final
|> Base.encode16

# Line 3 opens up a stream, and we're reading in 64KB chunks from the FS which is roughly pretty efficient
# In line 4, we initialize our hash (which returns a context) and put that as the default value in the reducer
# The hash_update in the reducer returns the modified context. Remember arg1 is the item, and arg2 is the accumulator

Movie Ticket Kata

First, head here to join our Zoom meeting. It will help me following along while you work through the assignment.

What Are We Building?

Write a program that calculates purchase price for movie tickets using any language you like. It should not be a full-blown web app; it can be a simple class or collection of methods invokable by your test suite. We'll provide you with some requirements, test-cases, and even a sample interface - all you have to do is give us some software.

An agile designer should be able to articulate goals and risks and users, frame hypotheses, estimate stories, prioritize work, draft a product roadmap, derive MVPs, run a standup meeting, participate in Design Crit, onboard a new teammate, talk to stakeholders, whiteboard a userflow, win an argument, lose an argument, cut scope, write copy, facilitate a meeting, ask good questions, Get Out Of The Building, take orders, give orders, cooperate, act alone, analyze a new problem, lead a sketching session, let go of an idea (even when it's yours), parse analytics, design experiments, distinguish a bug from a chore, conduct a usability test, tell hard truths in a retro, accept hard truths in a retro, design for delight, write CSS, debug Javascript, commit to Git, pair program, test-drive a feature story, model a domain, craft a brand identity, design a visual system, earn trust, give trust, fight efficiently, die gallantly. Specialization is for insects.
