Another thing to consider is that GrabCut is patent-encumbered for commercial use -- it relies on the mechanism described in Zabih, Boykov, and Veksler's "Fast Approximate Energy Minimization via Graph Cuts," which is patente

The advantage of GrabCut compared to the parent article is that it takes both color difference and similarity into account rather than just difference. This is done by combining all that information into a very cleverly-laid-out Markov Ran

When you say your 1 BTC is on your hard drive, do you mean it's on the hard drive of a running Internet-connected computer? If so, how do you address the threat of malware that searches for wallet files?

A Linux operating system has a core program called a kernel, which has the job of creating and maintaining an environment where other programs can run. Other programs include the login prompt, the shell that lets you execute programs, etc.

Why did the military require human beings to turn the keys if they expected people (and weeded out people unwilling) to turn the key blindly? A wire would have been much more efficient...

How do you define virtual? Is it limited only to simulations, or is it for any attempt to mimic nature? For example, organic compounds used to be considered impossible to synthesize due to a "vital force" until Wohler synthesize

There are two major competitors to the Von Neumann architecture, and then a few speculative ones. The most popular one is Harvard architecture, where code and data are in separate memories (improves security and performance, but makes load

What I believe low-level computing teaches you is that fundamental computation hasn't changed (architectural or system-level) for decades. We've had Lisp (and its associated software improvements) since the late 50s, protected me

A great way to become a cynic and pessimist about programming is to get a computer engineering degree. Once you understand computers at the gate & flip-flop level, you realize that most of what people argue about on the Internet is win

I think they should say that Google's lab rewards doing research, not rewarding failure. Managerial incentive systems' biases toward positive results holds the entire R&D community back.

This is Hacker News -- you are expected not to be sloppy with your argumentation here. If you say "inanimate object" rather than gun, then we're going to assume you are making a more general statement and react accordingly.
