In practice, for YC or similar Bay area US startups, they are the same.

All authorized shares are issued, and then the charter is amended through board action and more shares are authorized and issued at each stage.

Ya, I'd appreciate pointers if there are errors :)

This is US centric, it's mentioned on the first page, along with the notes and links.

Reinvesting is a minority, edge case. I can't think of a single VC company in the Bay area that can have founders reinvest shares and not cause issues raising.

"...reinvest shares." I don't understand this. I'm guessing it's my lack of knowledge.

I'd expect "reinvest" to mean "supply more capital to obtain more shares" in an attempt to maintain ownership percentage. The founder would have to already be rather wealthy, or be savvy enough to negotiate some other way to maintain their ownership.

You can borrow against your shares if you have a good relationship with the bank. That will allow you to be wealthy enough to buy some shares in the round. Not enough that you won't get diluted, but not as much as being broke. And of course, you have to pay back the loan.

Ya for sure, and even paid account is very cheap, few dollars a month

Thanks! :)

Depends on the outcome.

If it's a positive outcome, then preference has no role.

This game models good outcomes, with warnings for things like down rounds

Hey thanks!

There are a ton of edge cases, but the goal was to serve as an intro, and to get a grasp of the basics.

Links in the intro to a more serious look at things.

Quick honest question: What benefit did Viam bring that isn't brought by ROS for this project?

Hey all, this is from a team member of mine at Polymath Robotics.

Ask/comment away!

I would think most of the robot's sensors are numbers how do you turn those into messages that can be handled by a SM or BT?

Absolutely part of the plan, there will always be strange situations that the vehicle can't adapt to. So it has to stop and phone home.

Our current test vehicle uses remote operation a lot!

In fact, during our interview with TechCrunch we let Kirsten drive our unmanned test vehicle from her browser at home!
