I prefer the guide to be extensive like this one because it give me a sense of what I know and don't know.
Readings books is awesome because you are getting the condensed knowledge that someone have spend maybe decades of their lives to compile. When I listen to a podcast the same applies to a lesser extend. The problem is Lex does not ask interesting questions. He dwells into philosophical and common questions i.e "What is the meaning of life", "is math invented or discovered". This questions are interesting but are not in the guest field of expertise which in turn causes them to give a generic response. This devalues the quality of the podcast.
Yep after playing around with it for a bit it didn't give a minimum path. I believe something is wrong with the heuristic you are using.
Edit: You can prove A* will give a min path as long as: heuristic(x to y) <= min_cost(x to y). Problem seems to be here https://github.com/ssaric/algoviz/blob/master/src/util/GridN... I think it should be a matter of removing "times 100"
It is so sad that I can no longer control what my own car does. This is only about to get worse as tech improves.
Heck our phones and computers are probably sending thousand of telemetric information right now and we don't know or control. It just a matter of time until cars do that to, and we cant not longer control who to utilize our own cars.
Case 1: Netflix. Netflix caused innovation in the movie rental industry. But when Netflix first began it had much smaller market share compared to blockbuster. Would Netflix innovate again? Sure, but I doubt it would do anything revolutionary again. Most likely it would grow stagnant, once the new market stabilizes between hulu, HBO, disney, amazon etc.
Case 2: Apple. Apple was the underdog in early 2000s and that caused then to innovate, while Microsoft had grown stagnant. Today both Apple and Microsoft sort of have similar market shared and they don't really compete with each anymore. Microsoft shifted to cloud, and dropped windows phone. Apple keeps doing what they are doing with marginal upgrades to iphones, and mac. I don't really expected to come up with another "iphone" level innovation any time soon.
Case 3: Amazon. No big company is really trying to compete with amazon this days. I don't see Google or Facebook coming up with own online stores. It just not worth it to compete. While they are a lot of smaller online stores.
Case 4: Automobile industry. Sure they are new car models each year...but it is nothing revolutionary. Simple marginal upgrades over last year model. It was not until an underdog (tesla) tried to gain market share that we have seen any sort of innovation from them.
Most of the innovation today happens at smaller companies, and they eventually either succeed and become the next Apple and Google, fail and go out of business, or they get bough by the big companies.
In the case when one company's market share is smaller than the other it is always better to "invest" or compete.
What does it means to compete? It could mean many things like not putting lower prices, delaying innovations until competitor has release their own etc.

A's reward for competing will be n - a = b.
A's risk for competing will be a, (it's remaining market share).
A's will compete as long as the reward is greater than risk.
This will reach an equilibrium at a = b.
Do people here think it sound reasonable?
Edit: Mathematically the argument would be as follows:
Consider two company A and B. A has market share 'a' and B has b. n is the total market. Then a + b = n.
A's reward for competing will be n - a = b.
A's risk for competing will be a, (it's remaining market share).
A's will compete as long as the reward is greater than risk.
This will reach an equilibrium at a = b.
