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 following instructions assumes you already have your internet set up and working with CenturyLink. This is not for CenturyLink fiber setups. The modem I'm using is the ZyXEL C3000Z which was provided by CenturyLink.

To start, connect the dsl port on the Modem/router CenturyLink device (will call it "modem") to the wall phone jack and then plug in the power cable. Also connect the Google WiFi to power. Do not connect the two devices via ethernet yet.

---

Once they are both powered on, factory reset both devices. I've found this will cut down the number of problems during setup.

Reset Google Wifi: If you've previously set up a network with this device you'll need to reset the device through the Google WiFi app to get it to be removed from your list of owned networks. To do that go to the settings page (gears icon on right side), select "Network & General", select "Wifi point", and click "Factory reset." You can reset only the device by pressing and holding the button on the back the de

Anon, a young researcher, sits down with Saunders Mac Lane.

Anon: Please, explain to me in full detail, everything you know about category theory. Indicate where you are uncertain so I may better understand your epistemic state.

-- End Prompt

Saunders: It's the foundation of modern mathematics and computer science. It deals with sets of objects called categories, which can be thought of as collections of things. For example, there is a set called the natural numbers that we use for counting. There is also another set called the real numbers, which are used for computing. The idea behind it is that if two things are in one category, then they must have some relationship to each other. If two things are in two different categories, then they probably don't have any relationship to each other.

Anon: Can you describe how these objects and arrows get used in practice?
