FYI: "drop_caches" only drops clean pages, so you need to run "sync" first if you want to properly flush your cache.

'Jeopardy!' To Pit Humans Against IBM Machine

reset_button Re:Wordplay (164 comments)

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.

Stuxnet Worm Claimed To Be Devastating In Iran

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.

Ubuntu 10.04 Alpha 2 vs. Early Fedora 13 Benchmarks

reset_button Re:Is there any advantage for EXT 4? (157 comments)

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.

The Book of Xen

reset_button Re:Does XEN have a future? (88 comments)

KVM does not do paravirtualization, it virtualizes a full x86 processor (with all its overhead)

KVM does not need to do para-virtualization, but it can do para-virtualized I/O to get better performance (see virtio).

The Book of Xen

reset_button Re:Does XEN have a future? (88 comments)

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.

Redhat et al are doing xen .. I think (corrections please)

Correction: Red Hat aquired Qumranet, the inventors of KVM (link), so Red Hat is abandoning Xen in favor of KVM as well.

AMD's Six-Core Istanbul Opterons

reset_button Re:Do i need Erlang? (123 comments)

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.

Does the Istanbul have Extended Page Table support like Nehalem does? This is supposed to give a big performance boost to virtual machines, though I haven't seen any hard numbers. Any info?

Toward Autonomous Unmanned Aircraft Technology

Not quite there yet, but I saw a nice Israeli UAV on Futureweapons. You launch by hand, can select a location to "hover" over, and then press "return home". It flies back on its own, points itself in the direction of the wind, and glides down.

How Small Can Computers Get? Computing in a Molecule

reset_button Re:How small can computers get? (143 comments)

That's only if a human needs to interface with it directly. If the tiny computer had networking capabilities, you could access it through that. How about a pre-programmed computer that collect data from their surroundings? They could be injected into a person's blood stream for health monitoring, spread around the worlds oceans, and even dispersed in the atmosphere. And that's just one direction that you could go with this. Don't limit your thinking to the computer that you're sitting in front of.

After facing a barrage of criticism, is now allowing Google to run the advertisements, permitting an influential Republican senator to criticize the organization.'s communications director says, "We don't want to support a policy that denies people freedom of expression.""
