This is the exact opposite of my experience at AWS. Amazon is all about blameless fact finding when it comes to root cause analysis. Your company just hired a not so great engineer or misunderstood him.

Looks like something common between the control plane and data plane failed or there is a run-time dependency between the two (bad!) and that dependency failed.

I don't believe 2.5 hours is representative, so please cite these studies. Personally,senior engineers (individual contributors) that I have worked with spend 4-6 hours per day making significant contributions on their own and the other 4-2 hours working/coordinating with their team and sister teams. The only plausible scenario where one can do an acceptable job in 2.5 hours per day is where a senior person is doing the job of an entry level person. For people managers, having effective 2-4 hour days on an ongoing basis are very unlikely in my experience. I am open to be surprised with examples that prove otherwise.

Towers of Hanoi problem (simple version with 3 towers) is a good practical recursion problem that is stimulating and good for visualization.

This summer my kids (elementary & middle school) did the Intro to JS and Advanced JS courses. They really got hooked due to interactive creativity and video lessons. The audio narrative was really fun and kept them interested. Therefore, videos and especially the audio narrative style in Intro to JS is something I would vote for and hope that Khan academy continues that even (and especially) for CS courses.

I hear there is a river named Amazon in Southern Hemisphere and there are people landing in Seattle for river expeditions.

All I see in your argument is preconceived opinions with speculative statements and nothing to back them up. Sorry but you did not add anything to this discussion, not even in the form of new questions or pointing out flaws in the post's arguments using evidence.

You are assuming that their Business model is to profit from the difference in cost of shipping and prime subscription revenue. Rather than profit from a higher purchase volume if one has prime shipping than not.

I for one have observed that I have bought more things since I have had prime shipping. There is something to be said for the quick response to your order in the form of 2 day delivery.

<sarcasm> Right!!! </sarcasm>

Wish I could upvote more than once.

Ditto. Definitely seems like it has the potential to be the Killer app based on the viral potential of P2P, anonymity and widely adapted OS platform. All the best.

That is fantastic info about actual execution, many congratulations to you. It will be great if you could please share your age group range (very roughly; 20+, 30+, 40+ etc). Just trying to relate the results with the age group.

Start with www.coursera.org. There, you will find classes with varying degree of difficulty. If you can, audit a computer science class in the nearby college/university. Build something that you think you would be able to use yourself. Build it bottom-up, one small feature at a time.

I agree with the other observations here that the timings aren't even in the ballpark. For North Denver Metro area, it is displaying 50-60mins for places that are 25 mins away in rush hour.

+1. OpenPhoto offers the freedom of storing my photos in the storage I own and it is something I really care about. Besides, it is an open source project. I can even run my own server if I wanted to!
