IBM’s Watson supercomputer destroys all humans in Jeopardy practice round (video!)

So, in February IBM’s Watson will be in an official Jeopardy tournament-style competition with titans of trivia Ken Jennings and Brad Rutter. That competition will be taped starting tomorrow, but hopefully we’ll get to know if a computer really can take down the greatest Jeopardy players of all time in “real time” as the show airs. It will be a historic event on par with Deep Blue vs. Garry Kasparov, and we’ll absolutely be glued to our seats. Today IBM and Jeopardy offered a quick teaser of that match, with the three contestants knocking out three categories at lightning speed. Not a single question was answered wrongly, and at the end of the match Watson, who answers questions with a cold computer voice, telegraphing his certainty with simple color changes on his “avatar,” was ahead with $4,400, Ken had $3,400, and Brad had $1,200.

Alright, a “win” for silicon for now, but without any Double Jeopardy or Final Jeopardy it’s hard to tell how well Watson will do in a real match. What’s clear is that he isn’t dumb, and it seems like the best chance the humans will have will be buzzing in before Watson can run through his roughly three second decision process and activate his buzzer mechanically. An extra plus for the audience is a graphic that shows the three answers Watson has rated as most likely to be correct, and how certain he is of the answer he selects — we don’t know if that will make it into the actual TV version, but we certainly hope so. It’s always nice to know the thought processes of your destroyer. Stand by for video of the match, along with an interview with David Gondek, an engineer on the project.

Update: Video of the match is up, check it out after the break!

Update 2: And we have the interview as well, along with a bit more on how Watson actually works.

Gmail Adds Spell Checker to Its Search Box [Gmail]

Wondering why nobody’s ever written to you about a comunique? Pondering why there’s no mention of dispinsation in your inbox? Gmail now suggests correct spelling searches, kind of like its bigger search brother. In fact, Gmail has a little ways to go in catching up to Google in search capability, as Google Operating System points out—just an option for relevancy sorting would be nice. What search powers do you wish you had in Gmail that you're currently making due without? [Google Operating System] More »







FireWire ships its two billionth port, still not as fast as USB 3.0

The 1394 Trade Association has announced that over two billion FireWire ports have shipped worldwide, which is most impressive for a largely forgotten interface. Going forward, the Association expects to see “steady, stable growth” in 2011 as more products with FireWire S1600 go to market, though a dearth of such devices at CES makes us think you can add the word ‘slow’ to that projection. Given that the standard’s promised 1.6 Gb/s bandwidth is less than a third of the 5 Gb/s offered by USB 3.0 (even with USB’s larger overhead, 3.0 still provides a bigger pipe), and the fact that Intel may finally get on board with Superspeed, it may be awhile before FireWire celebrates another such milestone.

Windows 7 Service Pack 1 close to release

An update to Windows 7 released yesterday has given a strong clue that a final release of the first service pack for the operating system isn’t too far away.

According to a Microsoft support page, the imaginatively-named KB976902 (Windows 7 and Windows Server 2008 R2 installation software feature update) makes changes…

Study shows love for music relates to brain chemical, not to My Chemical Romance

It would make sense that people listen to music for the sheer pleasure of it, right? That’s what we thought, but apparently there’s a scientific reason for this. Scientists have discovered that when Earthlings listen to pleasurable music, one particular chemical is loosed in the gord. The study, conducted by Robert Zatorre and Valorie Salimpoor of McGill University in Montreal, concluded that when the participants tuned into instrumental pieces they were familiar with, their brains released dopamine into the striatum — an area of the noggin linked with anticipation and predictions. According to PET scans, the members of the study unleashed the chemical 15 seconds before a climaxical moment in a song, signaling the possibility that humans may actually release it in anticipation and not as a reaction to a wailing solo. Bonus point? Chopped and screwed tracks unleashed forty times more dopamine. Just kidding, but it’s probably true.

Toowoomba flood pics

The main purpose of this post is to share some photos sent to me taken by my cousin’s brother-in-law in Toowoomba. But first some context.

Paul Norton described the topography of Toowoomba thus:

Just to give people some idea of what seems to have happened in Toowoomba, the city of Toowoomba is located just on the west side of the Great Dividing Range. As you travel from Brisbane to Toowoomba, the road begins climbing slowly after about Grantham and Helidon, then climbs steeply west of Withcott before cresting the range at a bit under 700 metres. The eastern suburbs on Toowoomba are built on the western slope of the range, whilst the CBD is located in something of a hollow at the bottom of this slope, with gentler slopes to north and south. The “cloudburst” (to used Brian’s word on the older thread) on the range looks to have basically been funnelled into the CBD by the topography.

Further to my previous comment, the range forms a neat half-circle around Toowoomba on the east side, centered on the CBD.

That half-circle, according to the Federal member for the area Ian Macfarlane, is the rim of an old volcano, which has eroded away to the west, so the main street forms a virtual gully that drains away to the plains and into the Condamine.

The cause of the floods was a sudden downpour, described on TV as “nothing much” on the radar, but delivered 150 mm (six inches on the old scale) in about half an hour. The result was like a raging gully through the CBD and a vast amount of water down into the Lockyer Valley to the east.

So here are the Toowoomba pics. The first is a long shot of Russell Street:

Here are the flood waters at the railway crossing:

Followed by another street scene:

The next is a close-up of a building in the background of the second photo. We get a view inside someone’s home:

Home of resident with wall ripped away

I saw the occupant interviewed on TV. The torrent ripped away the side wall of his home exposing the inside with sagging floor.

Next we see the contents of a furniture store floating down the street:

Here’s a car wrapped around a post:

And another one somewhat the worse for wear:

Car mauled by Toowoomba flood

That’s it folks. What we see is a raging torrent that came and went fairly quickly in a place where no-one expected to see running water.

The Toowoomba Chronicle has some photo galleries, including this one. Here’s a sample:

Cars piled up in Toowoomba

The Courier Mail has quite an interesting home video of the incident here.

if you are discomforted by laughter towards the end, remember people laugh for reasons other than that they think something is funny. In fact I heard an extended interview once on someone who had done research on why people laugh. “Because it’s funny” from memory amounted to some 14% or one in seven of the instances.

ABC Southern Queensland has further information. I’ll leave you with a photo from this article which illustrates how angry the water was:

Google will drop H.264 support from Chrome, herd the masses towards WebM and Theora

We knew Google was rather fond of its WebM video standard, but we never expected a move like this: the company says it will drop support for the rival H.264 codec in its HTML5 video tag, and is justifying the move in the name of open standards somehow. Considering that H.264 is presently one of (if not the) most widely supported format out there, it sounds a little like Google shooting itself in the foot with a .357 round — especially considering the MPEG-LA just made H.264 royalty-free as long as it’s freely distributed just a few months ago. If that’s the case, Chrome users will have to download a H.264 plug-in to play most web video that’s not bundled up in Flash… which isn’t exactly an open format itself. Or hey, perhaps everyone will magically switch to Chrome, video providers will kowtow, unicorns will gaily prance, and WebM will dominate from now on.
