Excellent news for players of impact sports

Filed under: Football, Health, Technology — Tags: , — Nicholas @ 12:04

It’s becoming more a topic of concern for players (and especially for the parents of younger players) in sports which feature significant amounts of contact: detecting when a player has suffered a concussion. Football and hockey players are often determined to prove how tough they are by “playing through” injury, but concussions are not like bruises or other injuries — they can have long-term dangerous side-effects. There’s now a product available at the retail level that may help:

Over the next few weeks, a U.S. company called Battle Sports Science is making its Impact Indicator available throughout Canada and the United States. It is a sensor that is fastened to a helmet chin strap and detects when the user’s head undergoes an impact likely to cause a concussion.

Football versions of this device should be on the way to Canada in two weeks, said Battle Sports CEO Chris Circo, and one for hockey is expected to be available in late September or early October.

When attached and operating, a green light will be illuminated at the player’s chin. If the light turns red, it’s indicating that the player has been hit hard and should be evaluated before returning to play.

Once the technology is widely available, the professional leagues and the college and university teams should adopt them as standard equipment. Junior players would have less reason to resist using the device if all the top-level players were seen to be using them. It’ll take longer to retrain sports announcers to stop glorify big hits and featuring them on slo-mo playbacks while saying things like “He got jacked-up”, “They blew him up” and “He got his bell rung on that hit”.

Omnibus bills: Canada’s equivalent to “riders” on US legislation

Filed under: Cancon, Law, Liberty, Technology — Tags: , , , — Nicholas @ 12:09

An omnibus bill is a collection of several individual bills that may or may not have been able to pass muster individually. It’s (from the government’s point of view) a great way to get a lot of legislative changes through parliament in relatively short order, but it encourages legislators to include their pet projects and special causes because of the decreased opportunity for opposition. The Conservative government’s proposed omnibus crime bill is a good example of this, as it is likely to incorporate warrantless data searches for police:

When Canada’s Conservatives took the most votes in the May 2011 federal election, Prime Minister Stephen Harper said that an “omnibus” security/crime bill would be introduced within 100 days. The bill would wrap up a whole host of ideas that were previously introduced as separate bills — and make individual ideas much more difficult to debate. A key part of the omnibus bill will apparently be “lawful access” rules giving police greater access to ISP and geolocation data — often without a warrant — and privacy advocates and liberals are up in arms.

Writing yesterday in The Globe & Mail, columnist Lawrence Martin said that the bill “will compel Internet service providers to disclose customer information to authorities without a court order. In other words — blunter words — law enforcement agencies will have a freer hand in spying on the private lives of Canadians.”

He quotes former Conservative public safety minister Stockwell Day, now retired, as swearing off warrantless access. “We are not in any way, shape or form wanting extra powers for police to pursue [information online] without warrants,” Day said—but there’s a new Conservative sheriff in town, and he wants his “lawful access.”

How bad were the last set of “lawful access” proposals? This bad:

Even the government’s own Privacy Commissioner is upset about the lawful access idea. On March 9, Privacy Commissioner Jennifer Stoddart sent a letter to Public Safety Canada in which she and other provincial privacy officials said the bill would “give authorities access to a wide scope of personal information without a warrant; for example, unlisted numbers, e-mail account data and IP addresses. The Government itself took the view that this information was sensitive enough to make trafficking in such ‘identity information’ a Criminal Code offence. Many Canadians consider this information sensitive and worthy of protection, which does not fit with the proposed self-authorized access model.”

“In our view, law enforcement and security agency access to information linking subscribers to devices and devices to subscribers should generally be subject to prior judicial scrutiny accompanied by the appropriate checks and balances.”

The comfortable myth that the London rioters were “incited” by Facebook and Twitter

Filed under: Britain, Law, Technology — Tags: , , , , , — Nicholas @ 09:41

Brendan O’Neill points out the absurdity of the notion that the rioters in London and other English cities were organized and co-ordinated by use of social media like Facebook and Twitter:

The nonsense notion that the riot was orchestrated by thugs on social media is exposed in the fact that Twitter and Facebook and BlackBerry Messenger were stuffed with rumour and misinformation during the nights of rioting, rather than with clear instructions for where and how to cause mayhem. The use of social media was secondary to the violence itself, which sprung from the fact that urban youth now seem to have so little moral or emotional attachment to the communities they live in that they are willing to smash them up, and the fact that the police, the so-called guardians of public safety, had no clue how to respond and therefore stood back and let it happen. Incapable even of acknowledging, far less discussing, this combination of urban social malaise and crisis of state authority which inflamed the riots and allowed them to spread, our rulers prefer instead to fantasise that England was simply rocked by opportunists who love a bit of violence. And to fantasise that taking away their BlackBerries or restricting what they can say on Facebook — that is, curtailing youths’ freedom of speech — will make everything okay again.

How unique (and therefore how easy to track) is your web browser?

The good folks at the Electronic Frontier Foundation (EFF) have a new tool you can use to find out how easy it would be for third parties to track your browser usage, based on how it differs from others:

As you can see from my test (on a brand new machine), I have a unique browser configuration among the 1.7 million tested so far. My browser would be easy to track.

Charles Stross on the future of network security

Filed under: Science, Technology — Tags: , , , — Nicholas @ 12:40

Charles isn’t a professional in network security, but he has a good track record of exploring the consequences of new technology in his science fiction works. He was invited to give the keynote address at the 2011 USENIX conference.

Unlike you, I am not a security professional. However, we probably share a common human trait, namely that none of us enjoy looking like a fool in front of a large audience. I therefore chose the title of my talk to minimize the risk of ridicule: if we should meet up in 2061, much less in the 26th century, you’re welcome to rib me about this talk. Because I’ll be happy to still be alive to rib.

So what follows should be seen as a farrago of speculation by a guy who earns his living telling entertaining lies for money.

The question I’m going to spin entertaining lies around is this: what is network security going to be about once we get past the current sigmoid curve of accelerating progress and into a steady state, when Moore’s first law is long since burned out, and networked computing appliances have been around for as long as steam engines?

I’d like to start by making a few basic assumptions about the future, some implicit and some explicit: if only to narrow the field.

Google buys Motorola Mobile: it’s all about the patents

Filed under: Law, Technology — Tags: , , , — Nicholas @ 13:03

At least, so says Eric S. Raymond:

We’ll see a lot of silly talk about Google getting direct into the handset business while the dust settles, but make no mistake: this purchase is all about Motorola’s patent portfolio. This is Google telling Apple and Microsoft and Oracle “You want to play silly-buggers with junk patents? Bring it on; we’ll countersue you into oblivion.”

Yes, $12 billion is a lot to pay for that privilege. But, unlike the $4.5 billion an Apple/Microsoft-led consortium payed for the Nortel patents not too long ago, that $12 billion buys a lot of other tangible assets that Google can sell off. It wouldn’t surprise me if Google’s expenditure on the deal actually nets out to less – and Motorola’s patents will be much heavier artillery than Nortel’s. Motorola, after all, was making smartphone precursors like the StarTac well before the Danger hiptop or the iPhone; it will have blocking patents.

I don’t think Google is going to get into the handset business in any serious way. It’s not a kind of business they know how to run, and why piss off all their partners in the Android army? Much more likely is that the hardware end of the company will be flogged to the Chinese or Germans and Google will absorb the software engineers. Likely Google’s partners have already been briefed in on this plan, which is why Google is publishing happy-face quotes about the deal from the CEOs of HTC, LG, and Sony Ericsson.

You have to wonder why it took them this long

Filed under: Law, Media, Technology — Tags: , , , , — Nicholas @ 12:20

The New York City police department announced that it’s setting up a group to monitor Facebook, Twitter, and other social media in order to detect criminals who are stupid enough to boast about their crimes online:

According to The New York Daily News, freshly-appointed assistant commissioner Kevin O’Connor — styled as the NYPD’s “online and gang guru” — will head the new unit, which will trawl Web 2.0 for information on “troublesome house parties, gang showdowns, and other potential mayhem”.

The idea is to pinpoint net-savvy un-savvy juveniles who divulge their criminal plans on the web or boast about crimes already committed. You might think of them as Idiots 2.0.

In his former post with a north Manhattan gang unit, O’Connor apparently tapped the net for vital information on “a number” of shooting cases. In March, the Daily News says, the NYPD nabbed an eighteen-year-old who was part of a fatal beating after he boasted about the killing on Facebook.

(Temporarily) Drying out USS Monitor

Filed under: History, Technology, USA — Tags: , , — Nicholas @ 13:07

John Tierney reports on the conservation efforts on one of the most revolutionary warships in history:

[In 1861] a shipyard in Greenpoint, Brooklyn, launched not merely an ironclad but an entirely new kind of warship. The U.S.S. Monitor had no masts and no line of cannons. It was essentially a submarine beneath a revolving gun turret, something so tiny and bizarre-looking that many experts doubted the “cheese box on a raft” would float, much less fight.

But somehow it survived both the Navy bureaucracy and a broadside barrage to become one of the most celebrated ships in the world. Its designer and crew were the 19th-century celebrity equivalent of astronauts. Long after the ship sank in a storm off Cape Hatteras, N.C., the turret remained a cultural icon: an “armored tower” in Melville’s poetry, an image on book covers and film posters, a shape reproduced in items from toys to refrigerators.

Now the original turret, which was recovered from the ocean floor nine years ago and placed in a freshwater tank to protect it from corrosion, is on display again. It has been temporarily exposed to the air so that it can be scraped clean — very carefully, in front of museum visitors and a live webcam — by a team of researchers at the U.S.S. Monitor Center of the Mariners’ Museum here in Newport News. The team expects to have nearly all the barnacles and sediment removed by the end of this month, giving the public a new look at the dents from the Confederate cannonballs and shells that would have sunk any ordinary ship of its day. Then the turret will be submerged again in fresh water for 15 more years, until enough ocean salt has been removed from the metal to allow it to face the air permanently.

Another technical problem? Must be a day with a “y” in it

Filed under: Administrivia, Technology — Tags: , — Nicholas @ 21:44

Last week, you’ll recall that I was bewailing the failings of the Microsoft Windows Easy Transfer utility. Having given up on that and managed the transfer of files by the traditional tools of Brute Force and Ignorance (BF&ITM), I thought I was done.

All the necessary files now reside on the new laptop, and the old laptop has been dedicated to a new life as a genealogy workstation for Elizabeth. Today’s problem was network connectivity.

But not just network connectivity for the laptop, as I discovered when I tried turning on my desktop machine a little while ago.

At some point while we were away, the wireless router seems to have had some hiccoughs, because now it seems to imagine that it’s actually two separate machines. When I tried to connect to the internet this morning (from the new laptop), it insisted that I was connected to both a public network and our own named private network. But because it thought the public network was the primary, it refused to actually interact with our named network. It took several iterations of running diagnostics and power-cycling the router before the phantom “public” network disappeared and I was able to connect to the internet normally.

This evening, I had a similar problem with my desktop, except that my desktop machine is connected by ethernet cable, not wireless. That phantom “public” network re-appeared, and nothing I could do would get rid of it. The physical connections were fine, but nothing could persuade my desktop that it actually had a connection to the router and it was unable to get an IP address.

Having just bought a new laptop, I’m hoping that these symptoms do not imply that I need to also buy a new router, as you can imagine.

China discovers that “You can’t stop the signal” again

Filed under: China, Government, Media, Technology — Tags: , , , , , — Nicholas @ 12:32

Strategy Page looks at the way news was disseminated about the high speed rail crash despite the Chinese government’s attempts to quash the story:

Since July 27th, China got another reminder that it no longer can control the news. On July 27th, China’s high-speed “bullet train” had a fatal accident, leaving over 30 dead and many more injured. The cause was inadequate safety and communications systems. In this case, one train was halted by a flaw in the signalling system and another came up from behind and there was the collision that sent four train cars off the tracks, and a bridge. The government immediately tried to keep the accident out of the news. This effort failed because of the ingenuity of Chinese Internet users, despite the government ban on Twitter in China. The ban was meant to impede the rapid spread of news the government wanted to control. Given enough time, the state controlled media could get out a story the government could live with. But blog, RSS and other Internet tools have been tweaked to do the same thing Twitter does. This was especially true of “micro-blogs” that quickly distribute the same 140 character messages Twitter does. Not as well, but good enough, and the news the government wanted to control spread uncontrollably. This included pictures and video of the accident, which the government planned to keep out of the news.

Trawling a virtual economy to support a non-viable “real” economy

Filed under: Asia, Economics, Gaming, Technology — Tags: , — Nicholas @ 14:47

Give North Korea some credit for finding a viable source of revenue:

What’s a dictator to do when his third-world economy is wheezing along on its last legs? Hack some video games, of course! According to a report in the New York Times, North Korea’s Kim Jong-il unleashed an army of young computer crackers on popular South Korean online gaming portals to find ways to make quick cash.

South Korean authorities claim that a squad of approximately 30 hackers operated from a base in China and were given the mission of breaching online gaming servers (including those of the immensely popular Lineage) to set up bot factories and automated farming collectives. The digital booty was then sold to gamers for a reported $6 million over two years.

Addressing traffic congestion (in any city)

Filed under: Economics, Technology, USA — Tags: , , — Nicholas @ 14:03

Everyone knows that gridlock leads to wasted time and increased stress, but the effects of degraded mobility are worse than most people realize. Traffic congestion deprives job-seekers of opportunities, robs businesses of customers, and hastens the exodus of residents from the central city to the suburbs.

And although mounting gridlock may seem like the unavoidable result of increased population and strained budgets, the experience of nations from France to Australia proves otherwise. Reason Foundation draws on what’s worked worldwide and recommends a three-part plan:

1. Expand roads with underground tunnels and elevated structures.
2. Use pricing to keep traffic flowing.
3. Pay for new projects with private-sector financing instead of taxes.

That plan can help Chicago or any other city bust congestion and boost economic growth.
