  • The guy that created the subreddit, Violentacrez, was also the “victim” of an expose by Gawker who found out his real life identity. Reddit tried protecting him by banning links to Gawker when the article came out.

    I remember when this happened. Violentacrez himself showed up in one of the threads that didn’t get nuked and tried to defend himself. I remember his (heavily down-voted) comments all being surrounded by dozens and dozens of [deleted] comments — presumably people attacking him for being a pedo piece of shit.

    I’d never heard of the guy before, but I was so disgusted by the story and by his attempts to justify himself that I went back through weeks of his old posts, down-voting everything.

    The next day, I came back to a week-long temp ban from Reddit for vote manipulation. Fuckers.










  • Absolutely. And even if you don’t care that your cat is out there making kittens, it’s important to know that un-neutered males are much more likely to get into fights with other cats. A lot of the nastiest feline diseases spread through fighting, and fights result in injuries that can easily become infected. It’s not unheard of for males to lose eyes (or even whole limbs) to completely avoidable infections.

    So neuter your damn cats. It has the potential to extend their lives significantly, and promotes a healthier cat population in general.









  • Yeah, neutrino detectors don’t work like conventional telescopes because neutrinos don’t behave like light. Technically, neutrinos are actually a type of dark matter since they don’t participate in the electromagnetic interaction, and that makes them very hard to detect.

    When a beam of light shines on your body, some of that light is absorbed as heat and a lot of it is reflected off of you. Neutrinos don’t do that. Tens of billions of neutrinos from the sun hit your body every second and just… don’t do anything. They pass straight through you with zero interaction whatsoever. Very, very rarely they’ll interact with something, and neutrino detectors are designed to both maximize the chances of such an interaction happening, and to make those interactions more easy to spot.

    I’m not up to speed on all the technical details of JUNO in particular, but most neutrino detectors are searching for events that look something like this:

    A neutrino enters the detection medium and directly collides with an electron. Enough energy is transferred into the electron that it is stripped free from its parent molecule and moves through the medium at very high speed. If it moves fast enough, it can even exceed the speed that light travels through the medium, creating something sort of like a sonic boom — only with light. We call this Cherenkov radiation. The scintillating properties of the medium boost this signal and photomultipliers at the perimeter of the detector gather this radiation so that the event can be reconstructed by computers.
