Build your own proximity detector

(via MAKEzine blog)

proximity-detector.jpg

Come on!!!! You know you want one! Here’s my thinking on this project – build this, figure how to link it to your PC, and put up a couple around your cubicle at work. Suddenly, no one can surprise you by sneaking up to your cube because they are too short to see and detect over the wall. The Instructables guide mentions hooking it up to a sound playback device, but I think if you could hook it up via USB and write a driver to make a pop-up onscreen whenever the detector activates, you’d have a nearly perfect boss-detection-system (BDS) for work use.

UK to outlaw standby power mode?

(via PVR-wire)

“But I live in the US – I don’t care about that!” you might protest. And the truth is, for both of my regular readers, it probably doesn’t matter much (and I exaggerate – I doubt I have 2 regular readers). But this is a preview of a law I honestly expect to see come state-side eventually. Why? Well, check out the reason for a no-more-standby-mode law.

THE Government is to outlaw standby switches on televisions and video and DVD players to cut the amount of electricity wasted in the home.

Refrigerators, washing machines and dishwashers will have to become energy-efficient, and lightbulbs that burn too much energy will be phased out.

According to yesterday’s Energy Review, standby facilities use 8 per cent of all domestic electricity.

See that? Standby mode makes for 8% of domestic UK usage. Eliminating standby mode means after you turn off your TV, you’ll have to actually get your rear off the couch and push the power button on the box to turn it back on. This is because the remote-control power-on feature relies on the TV being in standby mode instead of being powered-off.

Of course, what more likely will happen is people will leave more equipment on when possible, thus increasing overall power consumption. But I’m just cynical enough to think people will take the lazy way out instead of the economical way out. Almost no one will notice the extra buck or two leaving on the computer or TV on will cost over a month, but they’ll remember having to drag that lazy ass off the couch to take three steps and turn on the TV with the button on the device.

Underwater image competition

I’ve already lost the source of this link. I think it’s another boingboing article, but I’ve gotten so many tabs opened to things I want to post about that I lost the original story. That said, go see some wonderful photos of underwater critters, the equipment used to see them, and some videos that go along with all that.

Biped robot kit

(via boingboing)
All geeky readers here, please raise your hands. Now, those of you with raised hands, keep them up if you’d like your own bipedal robot. Good. So, everyone who put their hands down – you can leave now – you’re not sufficiently geeky to be here. I deal with only high-level geeks, thank you very much. Those of you still here, check out the new Robo-One bipedal humanoid robot.

ROBO-ONE type bipedal humanoid robots were first introduced a little over four years ago. Almost all of the current designs have at least 16 or more servo motors, advanced controller boards, and fairly involved kinematics. That’s fine for the real devoted (maniac) robot fans, but as the robots have gotten more and more complex they have become way too difficult for the novice fans to master.

. . .

At the same time, Iwaki-san, the head of the Robot Force organization and a dedicated robot builder and competitor himself, believes that in order for number of robot players to increase dramatically, it must be FUN. Believe me, the Robo-Fight and Robo-Gong events are more fun than the proverbial barrel of monkeys, as we know from personal experience.

With that in mind, Robot Force set some basic design criteria for a low end, simple robot kit. In order to be considered a ‘humanoid robot’, their new robot would have to:

  • Have two legs and arms
  • Be able to walk around
  • Swing its arms to punch and fight
  • Get up from the ring mat either from a prone position or from its back

In addition, it had to:

  • Be easy for the customer to understand, build, program and operate
  • Have a low parts count with a minimal number of servos, since they are the most expensive single component in any humanoid robot design
  • Be low cost enough so that a large number of customers could afford it
  • Be a lot of FUN!

There you have it. Fun, easy to make, inexpensive, blah, blah, blah. What matters is this is a 3 servo robot that is designed to be more accessible than previous generation robots. And apparently, usable in robo-fights!!! Who doesn’t love a good robo-fight?

Australia continues to host freaky-scary creatures

(via Dubious Quality)

Last week in his Friday Links section, Bill posted about fanged kangaroos and the ‘demon duck of doom’ found in Australia. Given the absurdly deadly creatures already known to inhabit the country on land and in the sea, I suppose we shouldn’t be surprised to know there were even more deadly inhabitants in the past (psssst – this is the main link – the whole purpose of this post – if you skip the others, follow this one).

SYDNEY, Australia – Forget cute, cuddly marsupials. Paleontologists

say they have found the fossilized remains of a fanged killer kangaroo and what they describe as a “demon duck of doom.”

A University of New South Wales team said the fearsome fossils were among 20 previously unknown species uncovered at a site in Australia’s northwest Queensland state.

. . .

Vertebrate paleontologist Sue Hand said modern kangaroos look almost nothing like their ferocious forebears, which lived between 10 million and 20 million years ago.

The species found at the dig had “well muscled-in teeth, not for grazing. These things had slicing crests that could have crunched through bone and sliced off flesh,” Hand said.

Crunched? Damned kangaroos. I don’t think I want my bones crunched through, nor my flesh sliced off, thank you very much. Fortunately, these things appear to be gone now. Still, freaky-scary, I tell you. Oh, and freaky-scary is a technical term, I think. Although I haven’t verified that.

University-funded music subscription services failing

(via Freedom to Tinker)
The Wall Street Journal online provides some excellent details on how music services for students funded by colleges are failing. More importantly, there’s a lot of information on why these services are failing with the college crowd.

As a student at Cornell University, Angelo Petrigh had access to free online music via a legal music-downloading service his school provided. Yet the 21-year-old still turned to illegal file-sharing programs.

The reason: While Cornell’s online music program, through Napster, gave him and other students free, legal downloads, the email introducing the service explained that students could keep their songs only until they graduated. “After I read that, I decided I didn’t want to even try it,” says Mr. Petrigh, who will be a senior in the fall at the Ithaca, N.Y., school

I doubt most techies are surprised by this insite. We want movable bits. Free downloads to the hard drive are nice, but if we can’t move those bits to our portable MP3 players, burn them onto CDs to listen to in the car, or move them onto other computers we use, then we’re not so interested in those particular bits. Instead, we’ll find other places to get the bits in a format that lets us do what we want.

To stop students from pirating music, more than 120 colleges and universities have tried providing free or subsidized access to the legal subscription services over campus networks in the past few years. About 7% of all four-year schools and 31% of private research universities provided one of the legal downloading services, according to a 2005 survey of 500 schools by the Campus Computing Project, a nonprofit that studies how colleges use information technology

. . .

Purdue University officials say that lower-than-expected demand among its students stems in part from all the frustrating restrictions that accompany legal downloading. Students at the West Lafayette, Ind., school can play songs free on their laptops but have to pay to burn songs onto CDs or load them onto a digital music device.

There’s also the problem of compatibility: The services won’t run on Apple Computer Inc. computers, which are owned by 19% of college students, according to a 2006 survey of 1,200 students by the research group Student Monitor. In addition, the files won’t play on Apple iPods, which are owned by 42% of college students, according to the survey.

Hmmmmmm. Non-portable bits, disregard for 1/5 of the student body, and extra charges to get the format students want? Well color me surprised! I can barely fathom why the services aren’t doing well.

There is also little consensus among administrators about how successful the services have been in eliminating piracy. Although some say complaints from the recording industry have dropped sharply, no one can tell if that’s because fewer students are engaging in illegal file-sharing or if the industry simply doesn’t want to go after schools that are spending money to combat the problem. “The RIAA’s push to buy into these services strikes me as protection money. Buy in and we’ll protect you from our lawsuits,” says Kenneth C. Green, the Campus Computing Project’s director.

I buy this thought. I think most of the recording industry’s attacks on its own customers has been nothing more than a strong-arm tactic to get people to buy protection from the recording industry. Seems the mob might get a bit upset at the recording industry moving into their turf.

Here’s the kicker. What are students using for their music if not the freely available services? Oddly enough, it’s not the illegal services – Itunes seems to be the big daddy service, just like everywhere else. Imagine that – people will pay, if you make an effort not to screw them for staying legal.

Some schools that don’t offer free downloads dismiss the subscription services as too costly for the results they achieve, especially because so many students now buy music from Apple’s iTunes Music Store. “We were not in a position to offer an alternative to iTunes,” says Lev Gonick, the chief information officer at Case Western Reserve University in Cleveland. “The alternatives looked like they had more sizzle than steak.”

More sizzle than steak. I like that comment. And it seems about right.

Phishers getting more clever

(via Schneier’s security blog)

In an effort to fool more people, phishers have taken to using man-in-the-middle attacks.  In the past, if you thought a site was a scam or an email was a phishing attempt, you could enter bogus login information, see a success message, and know that the setup was a fake.  Now Washington Post has an article about phishers putting up a fake site and passing login credentials on to the real host site (in this case a bank, but also sometimes ebay, paypal, Amazon, and more) and using the response to determine what you see in response.  So if you enter bogus information, you will get a “Bad login” response from the fake host.  If you enter real information, you’ll end up forwarded to the real login success screen on the real host and the phisher will have a confirmed account.

The site asks for your user name and password, as well as the token-generated key. If you visit the site and enter bogus information to test whether the site is legit — a tactic used by some security-savvy people — you might be fooled. That’s because this site acts as the “man in the middle” — it submits data provided by the user to the actual Citibusiness login site. If that data generates an error, so does the phishing site, thus making it look more real.

By the way – Mr. Schneier predicted this last year (and really, it was a pretty obvious next step for phishers to take – I predicted it, too, but I’m not smart enough for anyone to listen to me).

More net neutrality discussion

Ed Felton is one of the good guys.  And he’s a bright cookie, too (perhaps I’m mixing metaphors).  So when he speaks about net neutrality, I read it with the expectation that what he says is better than what I would come up with on my own.  With that in mind, I looked at his latest net neutrality article and saw his the commentary by others on this topic.
First, Felton highlights the end paragraph from his net neutrality paper (the first link above).:

There is a good policy argument in favor of doing nothing and letting the situation develop further. The present situation, with the network neutrality issue on the table in Washington but no rules yet adopted, is in many ways ideal. ISPs, knowing that discriminating now would make regulation seem more necessary, are on their best behavior; and with no rules yet adopted we don’t have to face the difficult issues of line-drawing and enforcement. Enacting strong regulation now would risk side-effects, and passing toothless regulation now would remove the threat of regulation. If it is possible to maintain the threat of regulation while leaving the issue unresolved, time will teach us more about what regulation, if any, is needed.

With this starting basis, he then writes on a response by Bill Hermann, from the Public Knowledge blog.  Essentially, Hermann writes that Felton’s wait and see recommendation is not smart.  If we wait too long, he argues, the topic will no longer be highly visible, and getting policy-makers to see things our way will be harder and more likely to fail.  This sounds well-reasoned to me.  I can certainly see the point, and after reading Hermann’s article, I’m starting to think maybe he is thinking better about this than Felton.  Then, however, Felton puts up part of the rebuttal to this from Tim Lee over at The Technology Liberation Front.

Lee’s response is extremely well-written, I believe.  And after reading it, I start to feel swayed back to Felton’s way.  Of course, since I’m not as good about thinking these things through carefully, I find myself writing about others far more often than writing my own commentary.  Lee points out how many times laws and regulations have been put in place to stop big business from taking industries over only to have those laws bent, twisted, and modified over years and years.  In the end, these bastardized laws then become the things which support big business controlling what was once off-limits and erecting barriers to entry to stifle competition.

So let’s say Herman is right and the good guys have limited resources with which to wage this fight. What happens once network neutrality is the law of the land, Public Knowledge has moved onto its next legislative issue, and the only guys in the room at FCC hearings on network neutrality implementation are telco lawyers and lobbyists? The FCC will interpret the statute in a way that’s friendly to the telecom industry, for precisely the reasons Herman identifies. Over time, “network neutrality” will be redefined and reinterpreted to mean something the telcos can live with.

But it’s worse than that, because the telcos aren’t likely to stop at rendering the law toothless. They’re likely to continue lobbying for additional changes to the rules—by the FCC or Congress—that helps them exclude new competitors and cement their monopoly power? Don’t believe me? Look at the history of cable franchising. Look at the way the CAB helped cartelize the airline industry, and the ICC cartelized surface transportation. Look at FCC regulation of telephone service and the broadcast spectrum. All of those regulatory regimes were initially designed to control oligopolistic industries too, and each of them ended up becoming part of the problem.

. . .

Finally, it’s important to note that the iron triangle goes both ways: once you pass network neutrality regulations, repealing them will be very difficult. This follows from the same iron triangle analysis he used above—if the telcos figure out how to use the rules to their advantage, they’ll lobby just as hard against repealing them. (just look at the legal fight to liberalize cable franchises) Which means that no matter how competitive the broadband market gets (and there could easily be dozens of wireless broadband providers a decade from now) the regulations will likely stay on the books.

All in all, a very compelling argument for waiting to see what happens.  As noted above, if laws are pushed through to protect ‘net neutrality, we are probably just as likely to find ourselves wanting, but unable, to repeal or change them in the future as we are to be satisfied with them and be happy we have them.  So protect your ‘net rights – don’t do anything about them until you have to.

Slow times

Between illness, travel, and spending time with the wife and children, I’ve had even less than typical spare time to work on the site.  I have tried to at least get a couple of articles up per day these past few days, but I’ve fallen short.  I’m going to be on travel the next couple of days again, so again posting will be slow.  I expect to have time beginning Sunday to start catching up again.  If this works out, look for 10-20 articles a day as I catch up on my backlog of blog/news/gaming reading.  I am trying my best to resolve these slow times in a way that keeps the site more active.  We shall see over the next few weeks how well I can work this out.

Automated Master Lock crackers

I don’t link to Hack-a-Day very often, which is shameful on my part, as it’s an excellent site.  The latest article that caught my eye is one on Master Lock automated “cracking” machines.  And if you aren’t interested in the robotic crackers, there’s a link to a guide on opening these locks yourself in about 10 minutes.

Auto fuel from cow manure

My, what those Germans won’t do to stay ahead of the energy crisis!  In this case, it’s looking to cow manure as a source of energy.  Of course, in this instance, this Modern Mechanix posting shows us the Germans were doing this in 1949.  But maybe the whole technology will make a big come back with these soaring fuel prices we’ve seen of late?

THERE’S an old European proverb which says you can measure the extent of a farmer’s prosperity by the height of his manure pile. That saying is closer to the truth today in Germany than it has ever been before.

A German inventor named Harnisch has developed a simple device which converts manure into fuel. And this fuel is used to drive autos and tractors as well as provide household power.

The idea of using manure as fuel is not a new one. Cow manure has been used for this purpose for thousands of years in India and “Africa. As recently as 1912, many cities were operating gas lanterns on sewage gas.

Skeptical of the value of this technology?  You shouldn’t be.  Check out the supply ratio:

Methane from two cows is enough to heat the average farm house. With 20 head of cattle the farmer can operate a tractor for 120 days!
