There are many hard problems here. Today's search engines get keywords and return websites that are sorted by relevance. Watson will need to figure out what the question (well, answer) is, and then retrieve a single precise question. This is really pushing computing to a new level.

Beating Kasparov was nice, but this is much more difficult.

They are able to work and vote without restriction. That is not true of Christian and Muslim Arabs, living in Israel.

I bet you didn't know that you're incredibly wrong. Any Israeli citizen can vote, regardless of religion. There are currently 14 Muslim members in the Israeli parliament. Muslims study freely in Israeli universities and work in Israeli companies. The same is obviously not true for Jews in most Muslim countries.

Comment Re:Is there any advantage for EXT 4? (Score 1) 157

The problem isn't ext4 - it's an ext4 flag that gives you better data reliability in case of a power failure. If you're willing to risk it (or have a good UPS), you can change the flag and get all that performance back.

I also have to say that for a site that does so much benchmarking, phoronix is incredibly unprofessional. How about error bars on those bar graphs? Are caches cleared before each benchmark? Etc.

They're both Linux only at this point, and Xen effectively runs a forked version of Linux because it isn't, and won't be, upstream.

This is false. You can actually run various BSDs under Xen, and you can run Windows too.

I believe he meant that the hypervisor itself is a forked version of Linux. Sure, you can run any guest OS you want on both Xen and KVM.

Yea but properly use them? Today, the OS uses the cores in a pretty stupid way, and you end up with data structures being shared by cores, and so you need to lock them (expensive) and copy data between cores (expensive).

Once the operating systems handle them well, and application programmers are more aware of these issues, things will be much better in multi-core-land.
