Seeking the Oxford comma (in forbidden places)
The Oxford (or serial) comma is used to disambiguate
The Associated Press, strangely enough, doesn’t use the Oxford comma. But has the @AP ever tweeted using the Oxford comma
Scraped 144,000 @AP tweets, screened for potential uses of the Oxford comma, then manually screened the remainder to see which ones were actually used
Even the AP can’t resist the temptation of the Oxford comma! About 20% of the tweets where an Oxford comma could be, were there
Created a demo designed to demonstrate how security vulnerabilities work
Is this site vulnerable to cross-site scripting? Yes! On purpose!
Is this site vulnerable to SQL injection? Yes, and we can use that to steal Katie Fake’s $900 million account
Available as a secure and insecure version of this app, so you can see the mitigations of these types of attacks
OWASP is a good resource for how to protect yourself
Imagenet is a dataset with lots of images, and one label for what’s in the image
In 2011, the classification error rate was 25%. That has steadily improved since.
King : Queen is Man : Woman
Can we use a similar idea with Word 2 Vector to determine an analogous image?
Flute : Oboe is Cat : Lion
Lemon : Orange is Lizard : Frog
Sometimes it tries to extrapolate to determine what it thinks
Built in TensorFlow

Conway’s Game of Life - a popular cellular automation game with rules that determine how new cells are born or die: https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life
The game Go is kinda similar, but has different rules in that you’re adding a new cell every turn, and there are two types of cells.
So Nathan created a game of Go with rules that are similar to Conway’s game of life: https://aeium.github.io/Germ/
The victory condition for now is just one color left.
There are two windows: a game board where you place the pieces, and a preview pane where you can see the result of your placement
Bitcoin is a public ledger that uses cryptography magic to
Ethereum is Bitcoin but you can write actual code to the blockchain
VEX is the world’s most inefficient, most expensive calculator.
Travis sends his real money to execute a contract, and the result of the computation is forever stored in the blockchain
The language Solidarity is made specifically for Etherium, which compiles to a very small bytecode, which runs and executes the contract
