Check out http://www.raywenderlich.com/. One of the very best tutorial sites out there for mobile app development! Appcoda is nice too, although it's only for iOS.

Exactly! Big companies can learn a thing or two from this.

One possible interpretation is that they think the idea is great, but the execution is not.

"An artist by heart and hacker by profession" -> You are going to love Bay Area hackathons.

There are hackathons all over Bay Area almost every weekend. So pick the ones that interest you and give it a go. All good things start with people getting together at hackathons.

Startups need people. People need to have a life. SF offers precisely that!

prateekj | 12 years ago | on: What are some must-know algorithms?

Here are a few (in no particular order):

- Dynamic Programming

- Graph algorithms: Traversal (A*), shortest path (Dijkstra, Bidirectional, Floyd–Warshall), minimum spanning tree

- Recursive Search Techniques

- Search Trees (binary, n-ary, splay, AVL)

- Suffix trees

- Parsing using regex

- Sorting (with all the variations)

- Hashing

- Greedy Algos

- Divide and conquer

- Genetic algorithms

There are a few other algorithms that are must-know too. I guess that would depend on the domain we are in (computer vision, machine learning, NLP, etc).
