I want to write software that helps kill people.
Please, before you call the police and get my github account put on lockdown, allow me a moment to explain. What I really want to do is work on projects that advance the human condition and improve people's lives. I've been in a mad dash to learn how to program for the past four or five years exactly because I realized how much good I could do for the world with a computer.
| Hello scala, my old friend | |
| I've come to take you home again | |
| Because a feature slowly creeping | |
| left me plagued with doubts and weeping | |
| and the version that was tagged in the repo | |
| just has to go | |
| it lacks the signs of soundness | |
| On sleepless nights I hacked alone | |
| applying ant and other tools of stone |
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?
| // This file shows a hack to achieve operator overloading in | |
