collision

I just checked and there is no collision detection for usernames. You can signup for an account using any name and your account will seemingly just replace the previous created account.

Here's the dirty secret: All logos are designed in a momentary collision of experience and accident. All logos are, in a sense, designed in a weekend.

When a collision happens in a collider, we're actually preparing two plane waves and pointing them in the same direction. As they collide, the wavefunctions of the various fields become incredibly complex.

However, that seems to put her on a collision course with lots of not-so-savvy-but-they-don't-need-to-be folks who would be thrilled to make 1/4 of her reserve price. Ignoring credentials for a moment, does your wife have any skill which is commercially valuable?

The confusion comes from both the nature of the "fair use" defense and the collision of legal vocabulary and common language. Fair use is an affirmative defense, which means that even if a violation occurred in a strict sense, that violation is excusable.

Unless Google, eBay, Paypal and others who are committing these kinds of acts on a daily basis change their tune in a hurry I think that a collision with government action is unavoidable. A united front with government backing is probably the only viable option.

To out-pedant you: even assuming that the differential collision attacks we know about are incorrect [1], we absolutely know how to break SHA-1 given enough compute, that is, roughly the same resources needed to break RSA-1024. The answer is generic collision finding with parallel rho [2].

Visualize a bumper with sensors - as the bumper is deformed by a collision, a sensor shifts an electron in the copper wire, and the electron next to it shifts. There's a cascade of shifting electrons along the wire, and it races backwards through the car's body, chased by the destruction of the car as it collides with another object.

Edit: with regards to the charge of rudeness leveled against the conference organizers: In a world literally flooded by brands and names, name collision is not rudeness, it is almost inevitable.

The cross sectional area of the Earth divided by the area of space the object might possibly pass through yields the chance of a collision. With each successive night of observation, the orbital characteristics are determined to greater accuracy, and the cone of potential trajectories is reduced.

While a lot of these individual features alone are not impressive the sum of the parts, combined with the collision attack on the certificate signature are very impressive. As for the main point of Mikko's post, I have never understood why so many folks in the netsec industry are arrogantly pessimistic about the innovation of others.

Edit2: I got the interview after finding a bug in their authentication system that would allow a password hash collision to spit out the e-mail of the user that the collision occurred with. Meaning I type in a bogus email, and a password, after the post the login form would come back with the email pre-populated of the user that the hash collision had happened on, I type in the password again, and I was logged in as said user.

When you see a head-on collision and the person in the car walks away because the airbags went off, we don't argue for banning driving because the car is destroyed, there is $50,000 worth of damage to the guardrail, and hundreds of people lost work because they were caught in the traffic jam. We say, "Isn't it amazing how safe cars are these days! That accident would have killed them even 10 years ago." We have had a head-on collision between a late model nuclear reactor and an incredibly and extremely unlikely large magnitude double disaster and so far, the safety systems that were built into the reactors and upgraded over the years have kept everyone safe. Slowly, steadily, and with good engineering practices. The results of that disaster are being addressed and will be cleaned up and repaired. I realize that someone walking away unhurt from what would have been a fatal collision might feel that it was a miracle, but it might just have been good engineering.
