Supershuttle which offered shared vanpool rides to and from airports all across the US was shuttered partly because of competitions from Uber [1]. I personally find it a useful service given you can schedule it for early morning flights (6AM or earlier) without worrying about availability of drivers.

A 4-credit course is $5000 and a 3-credit course is $3900 (don't ask me why the cost per credit for each are not the same). There is also a one-time $200 transcript service fee.

With that said, if your employer has an educational plan that can cover the cost, then it is definitely worth pursuing. I am working on a AI graduate certificate and have just completed CS 221. The level of rigor in instruction and course work is far better than any online MOOC course I've taken.

Exactly. I used to be a mathematician and while I am no longer one, I can completely empathize with wanting to work on math as much as possible. To me, it's exactly the same as why some people want to run marathons, because it's exciting and immensely rewarding, and makes me feel alive.

Are nuclear bombs good? In the end it largely depends on how they are used.

In that case one can just spam the same (or similar) post every second and your feed will likely be filled with that post.

I know I'm setting up a bit of a straw man here but my point is even chronological order can be exploited.

> unless they started to select and/or moderate that content, at which point they would lose the carrier status

But since the homepage feed (or any medium really) displays contents in a certain order, some selection must take place.

Typically some algorithm (usually a recommender system together with some business logic) is used to determine which contents from all that's available to you are actually shown to you and in what order.

Bias seems to be an unavoidable part of the design to me.

Curious how Uber is planning to ensure the service 24 hours available? Anecdotally, it has been difficult recently getting rides before 6AM in the morning on a few occasions.

In case you feel sleep is a waste of time, it could actually be surprisingly productive to sleep. Once thing I noticed in grad school is that your sub-conscious is passively working on the problems you encountered even if you are not actively thinking about them. And often I would "dream" up a clever solution to a homework problem during my sleep.

From what I learned in the wonderful Coursera course: "Learning How to Learn", these are manifestations of the unfocused or diffused mode of the mind, and play a critical role in learning and problem solving.

Tesla's Autopilot has purportedly caused crashes already: https://www.bbc.com/news/technology-49594260

Good news is there were no injuries in this incident.

But there are also cases of fatality blamed on Autopilot: https://www.bloomberg.com/news/articles/2019-05-01/tesla-sue...
