Remember I said hackers aren’t just the guys who steal your credit card number?

Sunday, December 28th, 2008

Well, sometimes, they are really 1337 elitist Cambridge hackers who figure out how it’s possible to steal your credit card number when you use it at the cash register.

Then, occasionally, they go to German hacker conferences and explain how to do it. Hint for those of you playing along at home: it involves power drills, acid, and paperclips. Sometimes, they show off their method on a special BBC news report and leave a representative from the banking industry spluttering and making excuses.

Money quotes:
@15:15:
“I think the important thing to remember from this piece is that we’re not talking about a break of the chip & PIN security overall.”
“Well I think, according to that, we certainly are.”
@17:10:
“Let’s clarify, the system is not vulnerable. Chip & PIN is very secure. It’s not 100% guaranteed against fraud—”
“So it is vulnerable.”
“No, there’s no guarantee, 100% against fraud.”
“So it’s vulnerable! By definition. If it’s not 100% guaranteed, it’s vulnerable.”
@19:19:
“So despite the fact that new cards have enhanced security, the old cards don’t lack anything by not having it? Are you seriously saying that?”

Note to American newspeople: This is called a real interview. I realize it may look strange and unfamiliar to you. The person on the right is called a journalist, his job is to ask hard questions to his interview subject, and not let her get away with answers that are blatantly absurd or self-contradictory on their face.

Road Wearier

Friday, December 19th, 2008

I’ve been traveling for just under five months now, and I think it’s starting to get to me. Some combination of being on the road for so long, being away for the holidays, and the fact that it gets dark at about 4 pm (!) here makes me feel very tired and sluggish. Maybe I have SAD.  If I’d timed this trip better, I could’ve had two summers, one in the northern hemisphere and one in the southern. Instead, I get like two half-summers and twice the autumns.

It’s not homesickness, exactly, because I don’t really miss just being home, although there are a few people I’d really like to see. I’m having a great time. I think I’d just like stay someplace for a while. In a day or two I’m going to Frankfurt to spend Christmas with some family there, and after that I’m going back to Berlin for 25C3, which should be amazing. I like Berlin, and I might try to settle there for a few weeks at least. We’ll see.

I’ve been spending a lot of time lazing about and reading. I’m most of the way through Steve Wozniak’s (the co-founder of Apple computers) autobiography, the trendily-titled iWoz. It’s a good read, and Wozniak is truly an impressive hardware hacker and old-school geek of the highest order.

His original idea for the Apple was to create a powerful, but accessible, low-cost computer that hobbyists and ordinary individuals could use—as opposed to the $10,000 machines that preceded it. It’s almost sad, considering the direction that the Steve Jobs-dominated Apple has gone in recent years: producing overpriced computers-as-art-objects.

One of the first projects Jobs and Wozniak worked on together was the Atari game Breakout.  Wozniak stayed up for four days straight killing himself to meet a deadline. Jobs split with Wozniak the $700 wage he’d been paid for the project, but kept secret an extra $5,000 bonus he’d received from Atari for the pair’s efficient use of components. In his book, Wozniak claims not to be bitter about this, but it does  say something about the character of one, Steve Jobs.

I’m internet-famous!

It’s like regular fame, only without any of the wealth, recognition, or offers of sex that usually accompany it.

So Roboexotica was featured on BoingBoing Gadgets, the recently-launched BoingBoing spinoff which is kind of exactly like Gizmodo, Engadget, Gadgetizer, GadgetVenue, Wired GadgetLab, TheGadgetBlog, and Ubergizmo. Clearly, the world was crying out for a new gadget blog.

Anyway, the photo they chose for the story features none other than yours truly, driving Chassis! His creators were very kind in letting me drive their expensive, awesome robot. He’s fairly simple to control, with a two-joystick tank-tread-style control scheme. But the joysticks are analog, and his motors are actually pretty powerful. It’s easy to push too far and send Chassis careening across the room. Also, one joystick is a bit more sensitive than the other (“He has a limp,” they tell me) so you have to learn to correct for that if you want him to go straight at all. There are also buttons on the remote that make him blink, wink, dispense beer, or rotate the little metal fan on his head.

They also let me try the headset and take a turn doing the voice for Chassis, frightening small children when the robot talked to them (I was nice!) and amusing drunk adults.

0111 and 1000

Tuesday, November 25th, 2008

Monday were some “harder” tech talks and also my own presentation.

A guy named Paule Ečimović gave a talk about “Hacked Varieties of the Pong Computer Video Game Experience,” which was really cool. He showed the original version of pong, some of the later ports, and then some modern “hacked” versions, including my personal favorite, Plasma Pong. It used to be hosted here, before the author was sued by the withered husk of Atari (who somehow still have a legal department?), but you can still download it here and I highly recommend it. You’ll need a medium-decent computer though, Plasma Pong re-imagines the game of pong if it were played on a colorful, fluid field of plasma. It incorporates a pretty heavy-duty fluid dynamics model and fancy graphical effects.

HAIP day 100

Monday, November 24th, 2008

Friday was probably my favorite day as far as the lectures were concerned.

The first presentation was from Anders Carlsson of the blog Goto80 (eye-searing color scheme warning). He talked about the 8-bit demoscene and about chip music. He gave the presentation on an actual Commodore 64, and showed off some demos from the early 90s (keep in mind these are running on hardware less powerful than your phone). He talked about the demoscene as a “bounded culture”. They’ve been around since at least the late 1980s, but there’s been no real academic or journalistic interest, and very little crossover into the mainstream art or music worlds. Demos are shown at “demoparties”, not in art galleries. Occasionally, mainstream musicians will sample from the demoscene, but that’s about it.

Mr. Carlsson said that the focus in the demoscene was “craftsmanship, not art,” which I thought was an interesting distinction between the art scene and the more hacker-focused demoscene. The goal of a demo (especially in the 8-bit scene) is to push limited hardware to its absolute limit, and show off what an amazing programmer you are. To squeeze the maximum performance out of obsolete hardware means coding at a very low-level, in assembly or machine code (‘bare metal’ coding) and taking advantage of undocumented features of the hardware.
Another interesting thing about the demoscene is that authorship is protected by ostracizing offenders, not copyright lawsuits. As Mr. Carlsson explained, it would be “lame” to take somebody else’s code, or try to copy something that somebody else was doing. Recently Nelly Furtado and producer Timbaland sampled tunes from Finnish Amiga/C64 demo and have incurred the wrath of the Demoscene.

Another presentation was from a group called “Time’s Up” based in a waterfront warehouse in Linz, Austria. They seemed really cool. They’re a non-profit group with members from many different backgrounds interested in the “intersection between art, technology, science and entertainment”, and they construct “experimental situations”. They showed video of exhibits from their 2003-2004 “Sensory Circus,” which had a lot of different sort of mechanical and electronic constructions that visitors could play with. The goal of the Sensory Circus was to sort of disconnect people from their ordinary interactions with their senses and force them to approach the world in a new way. So, for instance, they’d have people walking around wearing a video-helmet with a camera facing backwards. Or a mechanical bicycle-like contraption that responds in unfamiliar ways to riders attempts to pedal forward, or steer it. The presenters explained that they were interested in creating “social hardware” and were more concerned with “the relational ‘why?’ than the technical ‘how?’” (To a true hacker, this is heresy: the how is the why)

The real crux of the presentation, however, was an uncompleted projected entitled “Twixtville”. The idea behind Twixtville was something like town-as-art. As explained in the presentation, Twixtville was to have been a “temporary, lived-in, ongoing, interactive, open, semifictional, proto-urban space, without governance.”
It would be a sort of make-believe town, inhabited by artists and fictional characters (or artists playing fictional characters?) with back stories and histories, and real and fictional conflicts. There would have been parties, workshops, and symposia (“I love symposia!”).  There also would have been some sort of online component to allow people to interact with the denizens of Twixtville.

Sadly, the project is now on hold indefinitely.  The main reason being an inability to secure a suitable location to host Twixtville. It’s too bad, because it seemed like an interesting idea. There are some examples of sort of temporary art communities, such as Burning Man in the United States, but the Time’s Up people said that they really wanted Twixtville to different, because it would be residential in that “people would really live there,” as opposed to a sort of festival.
