So, how easy will it be to deliberately search for an IPv6 address to collide with a desired pseudo_ipv4 address? (Based on my very limited crypto knowledge, I might worry that there could be some novel denial-of-service or impersonation at

Their FAQ explicitly says that they do not currently support RFC 3156, "MIME Security with OpenPGP" ( http://tools.ietf.org/html/rfc3156 ). I don't know this stuff well, but that makes me suspect that PGP&

I just came here to say the same thing. I remember, way back when, that this felt like the most natural thing in the world: type my password once, and then copy and paste what I just wrote to save myself the effort of typing it again. I eve

Before I start chattering, here's a documentary that really had an impact on me: http://www.firstgenerationfilm.com/ It was heartbreaking to watch the four(?) kids they followed go through this process making what (t

Interesting. While I had concerns similar to yours, it wasn't pre-existing ability on my mind but rather pre-existing "social class" (whatever that means). I teach at a college whose population is unusually high in first-ge

Thank you for that explanation! LaTeX docs constitute the vast majority of PDFs that I view, and I've wondered for ages why PDF.js seemed to be so laggy so much of the time.

I'm entirely on your side on this (PhD, UChicago, 2006), but there are still a bunch of physics teachers out there (mostly not doing research in related fields, is my rough impression) who will vigorously defend teaching the "rela

That was one point where I wasn't sure quite how to talk about this. In the back of my mind, I have a sense that "gets deflected more" (meaning "longer distance") is actually referring to the same fundamental proc

Thanks! (I'm a physics professor, so explaining stuff like this is pretty much my job. But my specialty is string theory, which is pretty far removed from radio astronomy!)

Maybe it's worth mentioning that we're all at least a little bit familiar with dispersion in other contexts: it's the same phenomenon that makes a prism work to split white light into colors, and that is responsible for rainb

I learned this a few years ago from a colleague in biology. He and his students routinely collect birds in nets for tagging and measurement, and he mentioned that it's important for them to check the nets every few hours when they&#x27

The phrasing of that section isn't entirely clear, but I think the idea is a little simpler than what you're imagining. What the article means is that if you have a single, very short emission of waves with a combination of multip

What business model do you envision for the web, then? Sure, my own websites are ad-free, but they're purely hobby projects and I don't feel like the (small?) income would be worth the personal discomfort of "selling out&quot

In what way? (I mean, yeah, far right wing reactionaries might take exception to it, but they probably wouldn't like a lot of other things I say or do, anyway.)

Honestly, I think there's a little something to this submission beyond the "Ha ha, lots of people made typos that could cause big problems" factor. A public repository like GitHub makes checks for common errors like this rea

In my experience, virtually all of Calc III is "visualizable" (even somewhat esoteric stuff like Lagrange multipliers[1]), because it's mostly about vectors (which have a natural geometric interpretation). My claim would be t

In particular, the NYT's new calculator is a reimplementation of the calculator you found by Francis Su and his student(s) (which it cites).

That's maddening. The really frustrating part is that this effect (and especially the "can't undo" part) is completely invisible to the user. Like I said, my wife missed out on some rather important messages about an upc

I guess I always assumed that spammers didn't particularly care whether what they do is legal or not (and certainly that they didn't much care whether the people they contacted wanted to get their messages). Is this a flawed impre

I'm really curious about this ISP agreement. My wife hit a bug in the new Yahoo mail interface that led her to accidentally mark a few messages as spam. She immediately fixed the mistake, but it turned out that (unbeknownst to her) she

First and foremost: I apologize for making a comment that came across as hostile. Perhaps my intent would have been clearer if I had said, "I don't think it WOULD BE fair to say...". I did not mean to suggest that you persona

I don't think it's fair to say that "modern diets are the problem ". The availability of modern diets is, after all, largely responsible for modern civilization (which was enabled by agriculture). But I think it's

Side note (as a scientist who uses the site): there are lots of different ways to share an arXiv.org link, but in almost every case the best option is this: http://arxiv.org/abs/1403.1211 That links to an abstract page

As I read the story, "Dads Resume" was a specific candidate, so named because that was evidently the filename of the email attachment. That said, there was at least one explicit age reference fairly early on. It put me on edge.

Right, so he's claiming that the genes responsible for this really pretty random list of traits ("protruding, cartilaginous mucous noses"? "Prostate encircles urethra"? "Alcoholism"?) were so strongly se

Thanks! I didn't realize that recombination was so frequent. I'm glad to have a better sense of that now.

I started using Anki this year to help me learn my students' names and faces, and it's been glorious. I was able to recognize about 75% of them on the first day of class, and within a few weeks I was solid on nearly everyone. That

I saw that claim in the article, yes. I'll admit that I don't know enough about genetics to make strong claims here, but it doesn't sound remotely plausible to me. He wants to simultaneously claim that 1) hominids got so much

by Steuard 13y ago
That's one of the most ridiculous things I've ever read. We've done genetic studies on humans and apes, and we share some huge fraction of our genome with them (99%+, right?). It's quite telling that in this era of abu
