Honest question: Are Chrome apps "File->Create Application Shortcuts" not available on Mac OS X?
Because on Linux you can create such apps very easily with this Chrome feature, and I'm pretty sure even cookies/history is separate from the main Chrome instance.

Actually, the author says that all dict operations take O(1) time, which is the best (or average) case and not the worst case. I think it should at least mention the worst case! No hash table exists where you get worst case O(1) (non-amortized) for all three of insertion, deletion, and lookup. You either have to resize the table at some point or you have to deal with hash collisions.
(BTW, I've been asked this question numerous times in job interviews and answering O(1) without qualifying the statement is definitely wrong.)
1. Mike's explanation is totally off the mark. Tesla's systems are simple helpers that work in specific circumstances only, and still require the driver to be responsible/react. The technology has been around for quite some time now. Google is building a complete self-driving car that basically replaces the driver altogether. This is much harder and you need to get it 100% right before shipping it, as your system will (most likely) be responsible for any accidents it causes. The "expert" seems to confuse robotic wayfinding with the challenges that exist for self-driving cars. There is a (very small) overlap, but the hard problems are not in this overlap.
2. The article linked is merely rephrasing the answer explained in a Forbes article instead of actually quoting the source. A simple link to the Quora answer would have sufficed.
Regardless of whether it is an ad or not: You missed a huge chance by submitting to HN before having the app ready. I find the idea of only a few categories appealing, but if I wanted to do this right now I would probably go look for an app that is available right now. I want to test your app for a week or so, give feedback and move on if it doesn't work. Not too keen on signing up on a mailinglist for an app that will "someday" be ready, unless I'm very excited about it or the app is the first one to solve a specific problem. Attention spans are short!
While the question is interesting, unfortunately the article didn't really present a good solution. At least I would have liked to see the results of more than one approach rather than just the one presented (which isn't really a solution IMHO).

Or is this better/different in some way?
