Be a computer scientist without the years (of hell)

Wednesday, December 24th, 2008

There’s one thing I regret about getting my Computer Science degree: the years of my life it wasted. Ok, ok, that’s not true. I regret way more than that :)

Anyhow, some guys at MIT have whipped up an Automatic CS Paper Generator. I love their rational:

One useful purpose for such a program is to auto-generate submissions to conferences that you suspect might have very low submission standards.

I’d bet most submission boards wouldn’t notice one of these coming in. Maybe I’ll reference a few of these bad-boys on my resume from now on ;-) Here’s my ground-breaking paper: A Case for Symmetric Encryption.

Have fun with your new found power, and I am in no way responsible if you get drop-kicked out of University for using one of these papers for your homework (you idiot).

Intel’s Wireless Power Technology Demonstrated (MIRROR)

Saturday, November 15th, 2008

This innovation is hoped to be embedded into tables and work surfaces so that as soon as a device is placed on the surface, it will be able to draw power. The technology uses magnetic fields to transmit up to 60 watts of power to a distance of up to two to three feet while only losing around 25% of the power during transmission.

A major concern of any wireless power technology is its possible effects on users. Fortunately during the demonstration the electricity was broadcast without electrocuting anyone who passed between the transmitter and the receiver. Intel’s lead researcher Josh Smith explained that, “The trick with wireless power is not that you can do it; it is that you can do it safely and efficiently.” Magnetic fields, used by Intel’s WREL technology do not affect the human body (at least as far as we currently know), unlike electric fields, which might give the user a zap.

The idea of using resonant magnetic fields to wirelessly transmit electricity was demonstrated by a team from Massachusetts Institute of Technology (MIT) who refer to their idea as WiTricity. More recently Intel researchers joined forces with MIT to explore the phenomenon known as ”resonant induction,” and the outcome is a technology capable of transmitting power several feet away without wires.

Currently, resonant induction is used to recharge small devices such as electric toothbrushes. Future induction systems based on Intel’s technology will not be restricted to a physical touch between transmitter and receiver and will be able to transmit power over a distance of several feet with efficiency of 50 percent or more.

“In the future, your kitchen counters might do it [supply the power],” Mr. Smith said. “You’d just drop your espresso maker down on them and you would never have to plug it in.”

The new technology would initially be used to charge the battery of devices such as laptops, cameras, and cell phones, but Intel hopes to eventually eliminate the use of batteries altogether. Enderle Group analyst Rob Enderle said, “That is potentially a world changing event. This is the closest we’ve had to something being commercially available in this class. Previous wireless power systems consisted basically of firing lightning bolts from sending to receiving units.”

Intel is not the only player in the growing market of wireless power companies. Many companies are currently working on different types of wireless power technologies. Two American start-up companies, WildCharge and WiPower, have already shown simpler wireless power technologies. Intel’s next target is to design a system to recharge a laptop computer without wires.

Intel looks on this next development as a strategic move since attaching a WREL receiving antenna to a laptop would be easier than trying to implement the WREL technology into cell phones or PDAs due to their small size compared to the WREL receiver. If successful, the system would be implemented in airports, offices, and other buildings and deliver power to laptops and other mobile devices. The technology could also be built into plugged in computer components, such as monitors, to enable them to broadcast power to devices left on desks or carried into rooms.

Smith says that Intel’s wireless power system is still in an early stage of development and much research remains before it can be brought to the market. “You’d like to cut the last cord,” Smith said. “It’s great that we have wireless email and wireless internet and stuff like that but at the end of the day it would be nice to have wireless recharge as well.”

You can read more about MIT’s first test of the technology mentioned above in “Wireless Power Demonstrated,” where a 60 watt light bulb was able to be lit wirelessly from a distance of about 2 meters in mid 2007. Another wireless power technology is currently being developed by the U.S. company Fulton Innovation under the title “eCoupled Wireless Power.” While waiting for all those wireless power technologies to be developed, you can check out a new, fully operational, green plug universal adapter, which helps you power all your devices from a single adapter.

More information can be obtained on Intel’s website and blog. Several videos show a demonstration of the WREL technology (here, here and here).

Large Hadron Collider Live

I feel safer already to have these webcams watching the LHC since I was convinced it was going to kill us all. What could possibly go wrong? :D

Android G1 phone shows you where you are

Tuesday, September 23rd, 2008

The new Google Phone was unveiled today (TechCrunch liveblogged the launch using ScribbleLive crossposting). I definitely want one to play with, but I won’t be dropping my iPhone cold just yet ;)

One thing I found kinda funny cool was that it comes with a built-in compass. It gives the phone its precise orientation when it comes to GPS positioning. Their big demo app was Google Street View that rotates on the screen as you rotate the device. So let-me-get-this-straight, if you are standing somewhere you can pull up a photo of the exact place you are. Oh, and if you turn around while you’re standing there, you can see the photos of what’s in-front of you over there. Yes, that definitely is a selling point :) I no longer have to refocus my eyes by being forced to look at a screen, then the real world. It’s a miracle!

Of course, I’m just trying to balance-out all the glowing reviews of the launch with a slightly negative one, for no particular reason. Don’t listen to me. Go enjoy your Google Phone and smite me down with your no-refocussing ways.

CRTC denies new TV channels that would compete with major broadcasters

Friday, September 5th, 2008

In Canada we essentially four major TV networks (sorry, CBC): CTVglobemedia, Astral, Canwest and Rogers. Between the four of them, they own almost ever analogue channel and a big share of the HD channels in Canada. The CRTC is a regulatory body for the broadcasting industry. In recent years, they have started allowing unprecedented consolidation of the media in this country. The rational has been that we need the Canadian broadcasters to be as strong as possible to be able to compete with the power of the U.S. networks. Of course, there’s no way that will ever happen, but that’s the rational ;)

Over the last few years, the Canadian broadcasters have been allowed for the first time to own multiple news stations in each city market, which has further narrowed the points of view that we are exposed to in the media. For example, in Toronto CTVglobemedia owns both CP24 and CTV Toronto. To make matters worst, CP24 airs mostly news from RogersCityNews, which shares content with 680 News Radio, etc, etc. You start to get an idea how consolidated the media is despite the CRTC’s “efforts.”

Given this state of the industry, we need more independent voices in the market, not less. So what does the CRTC do to respond?

CRTC slaps down application for new HD stations
In three separate decisions handed down today, the Canadian Radio-television and Telecommunications Commission (CRTC) turned down multiple applications from High Fidelity HDTV Inc. to operate two new English language high definitions and one standard definition channel in Canada.

The federal regulator denied the applications because the commission said the new stations would compete with stations owned by Canada’s largest television broadcasters: Astral, CTVGlobemedia, and Rogers and that would contravene the commissions “competitive policy.”

Although it is counter-intuitive to most readers, under the CRTC’s competitive policy, new applicants must convince bureaucrats in Ottawa that a new station would NOT compete with an existing analog or pay channel in order to receive approval.

In simple terms, the CRTC ruled that High Fidelity, the broadcaster of several HD channels in Canada including Oasis HD, Equator HD and Treasure HD, had dared to propose stations that would compete with stations owned by Astral, CTVGlobemedia and Rogers therefore the stations were rejected.
Diversion HD and Diversion SD

The CRTC is using outdated mandates to protect the major broadcasters and denying competition as a matter of policy. Can anyone explain to me how that policy benefits Canadians?! Combined with the CRTC starting hearings about whether they should regulate the Internet, this bureaucracy is completely out of control. Unfortunately, the minority Conservative government in Ottawa is no friend of the media industry. There’s little hope of them making tough decisions about the CRTC.

So I guess we’re stuck with this increasingly irrelevant, dinosaur office mucking about in an industry it no longer understands. I guess the moral story is: if you want to broadcast your content in Canada, you’d better look to the Web not the TV.

Melting icecap = just more land for us (and Gisele Bündchen)

Wednesday, September 3rd, 2008

So there are lots of stories out this week about the unprecedented melting going on at the North Pole. I’m still waiting for the first second scientist to come right out and say, “Yup, we told you this was going to happen. Now the Earth is going to absorb way more sun, which will heat the oceans, and trigger a massive climate shift.”

I think it’s obvious by now that we’re all pretty-much screwed at this point. So smoke-’em-if-you-got-’em people, and let’s live out the rest of our days squabbling over the Northwest passage. At least Canada will end up with more land…until the U.S. decides to annex our arctic. I hereby extend an official invitation to Gisele Bündchen to come live out her days up here in the sunny arctic with us :)

The Large Hadron Collider is trying to kill us

Wednesday, August 27th, 2008

For years I’ve been boring telling people about how the Large Hadron Collider at CERN is going to kill us all. Well I’m finally justified in my crazy ramblings thanks to a Cracked article, Cracked being the definitive source for all science articles :) I hope someone let’s me know when they first turn the LHC on. I know that if they screw up, I won’t have time to realize that I’m being sucked into a wormhole or something, but I’d still like to be sitting on a patio, drinking a beer, and contemplating how cool science is.

The article also waxes the finer points of nanotechnology:

Imagine you meet a magical leprechaun. For a bargain price, he offers to fix up the your house and add an extra room. So you take him home, and he proceeds to eat your house and shit out a hundred and forty more leprechans, which promptly murder you.

How It All Ends: An argument for immediate action on climate change

Friday, December 28th, 2007

Nothing like a great doomsday video to get you in that holiday spirit :) This guy was on Canada AM this morning. He makes a very logical argument for taking immediate action to counter global climate change, and has posted dozens of videos debating the finer points with skeptical YouTubers. Give it a watch, and decide for yourself. At the very least, he’s pretty entertaining ;)

Xbox 360 Convergence: Is it here?

Wednesday, December 12th, 2007

I just realized that last night I had the ultimate convergence experience on my Xbox 360:

I turned on my Xbox 360. I checked what my friends were playing, and decided to play some Halo 3. I played for a while, when a friend’s MSN message popped up on the screen. I waited for the game to end, then MSNed them back. While I was doing that, a friend from Halifax joined my Halo 3 team and asked me if I wanted to play. I hooked up the mic and me and my g/f talked to him for a bit. Then I decided to go to the gym for a bit, so I started some music streaming and my g/f played some Arcade games I had downloaded. When I got back, we started a Marketplace movie downloading. While that downloading, I watched an episode of Dexter I had on my computer. When I turned off the Xbox that night, I left it recharging my iPod and the controller through USB.

It can’t be at the point where this is all possible, is it?! All this was possible with a stock Xbox 360 and my Mac with Connect360 running. I’m very impressed with Microsoft right now :D

Xbox Media Center is awesome, but not quite HD

Sunday, April 1st, 2007

As you may have guessed already, I’m in love with my Xbox Media Center (XBMC). It’s a great media center for watching downloaded content. But even-though it’s pushing out a 1080i picture, the adage holds: Garbage in, garbage out. Although in this case, it’s more like recycling.

Most of the TV you can download out there are 350MB per half hour, multi-pass encoded in the Xvid codec. They look great, they sound great, but they don’t match the high-definition coming through the air or cable company. Even though they may be labelled “.hdtv.avi”, they have been encoded down from a high-definition MPEG2 down to an MPEG4. If you look at the true HD rips floating around out there, they are 4GB per hour. So despite Xvid being a great codec, picture information is being lost.

Here’s a look at the same scene, from the same show (’Lost’), on the XBMC vs. a Scientific Atlanta HD-PVR. Both screenshots were taken from a paused screen at almost the same timecode (you try pausing within a millisecond ;) ) with a Canon Powershot SD30 on a Sharp Aquos 32″ HD LCD TV.

Xvid on XBMC
'Lost' on Sharp Aquos via Xvid and XBMC

HD TV on Scientific Atlanta PVR
'Lost' on Sharp Aquos via Cable HD

As you can see, there is a fairly big difference. This is a pause, so you can’t see the motion effects. But differences in clarity and colour are pretty easy to see.

The sharpness just isn’t there in the Xvid. Look at the details of the woman’s face, and the stairs behind her. The Xvid is blurry whereas the HD has the clarity you have come to expect on a modern TV.

Also, check out the buttons on the woman’s jacket. In the HD you can see they are all gold/bronze, whereas the Xvid shades them each very differently (some even look green).

Although the Xbox Media Center is great for streaming downloaded (Xvid) videos to your TV, if you are used to high-definition television, you can’t get rid of your cable company or HD-tuner quite yet ;)
