Using dynamic programming, you can solve the TSP problem in O(n^2 2^n) time with O(n 2^n) space, n = #cities.

Did I miss something? How do I start this thing? Couldn't find it on Documentation..

I don't get it; is there a convention for contours? What do the colours stand for? Also, what is the scale of traffic that is represented?

Hasn't anyone attempted to simplify the UI for the ToS? Is it because a UI can be misinterpreted or anything?

It should be possible for the software to prefix "Ask HN" automatically. (if none exists..) But yeah, it just requires little effort from those posting the story. :)

There are more downsides. Given their example of how new webapps will seamlessly integrate into the browser by having their own toolbars and such (the google maps part), it would be very easy to craft a picture-in-picture phishing attack.

How is the transport layer implemented? Does it use TCP? Or does it build its own reliable transport over UDP? Of another concern is the message delivery latency.

Something related: there's a recent work called "tcpcrypt" that argues for "ubiquitous transport encryption" and scales better than HTTPS too. It's backwards compatible with TCP, does not require application rewrite, works with middle boxe

I am just logically arguing here, not in support for anyone. But hasn't Facebook worked "hard" to setup the infrastructure to "collect" users' data? If you want users' data, go ask the users; not via scraping Facebook.

Any plans of open sourcing this? What other features have you planned for it? Versioning? Like gist.github.com?

This seems quite similar to the FAWN project at CMU. http://www.cs.cmu.edu/~fawnproj/ The idea is similar: if IO is the bottleneck, instead of scaling up IO, scale down the CPU power.

One way to handle such breakage would be to define an extraction template on the fly, based on some content that doesn't change on the page. If, for e.g., you know that the stock quote for Google has GOOG and some number somewhere inside t

How many of you actually go to the Google homepage to search? With Chrome/Chromium, just type on the address bar; for Firefox have shortcut prefixes. (like "g hacker news" searches for "hacker news".)

Lot of attention to details. I liked the part where due attention was given to those without a temperature controlled water bath. Awesome!

From a video, it seems like the smooth application transitions/animations of the iPad is missing.

Even if servers are I/O bound, this setup is almost like crunching 50 machines into one; applications will have lower latency access to data stored on larger memory.

An interesting application of skip lists: http://www.skorks.com/2010/03/faster-list-intersection-using... But I can't see why the same cannot be done using trees. :-/

I see; what about cases where transactions involve objects at multiple servers? I guess I am confusing server specific locks vs client specific locks.

I don't understand how they could avoid locks. They say that each replica runs independently and hence that avoids locking; what about write updates to the same object from different clients? That would need locking of some form at some lev
