simon_··on Fraud U: Toppling a Bogus-Diploma Empire
I don't think that's fair. My computer science education was seriously enriched by the community of students and professors at Stanford, even if I could have learned the basic material mostly on my own.
simon_··on Reproductive biology: Girls on top
http://en.wikipedia.org/wiki/Human_sex_ratio

I believe it doesn't even out until relatively late late in life, with male mortality being slightly higher at all ages. From the wikipedia article:

The "First World" G7 members all have a gender ratio in the range of 0.95–0.98 for the total population, of 1.05–1.07 at birth, of 1.05–1.06 for the group below 15, of 1.00–1.04 for the group aged 15–64, and of 0.70–0.75 for those over 65.

simon_··on Threadless offering $1000 for positive ID of Chicagoans in these photos
Maybe I'm misreading Wikipedia, but it looks like False Light and Approbation violations would require (respectively) the dissemination of false information or some intent to gain financially.

However, it's probably true that these laws will be tested in unexpected ways as everyone gains the power to communicate with "the public".

This sentiment seems a little silly to me - there's no implicit right to anonymity in RL, especially if you go around pissing people off by stealing from them.
simon_··on Has dark matter finally been detected?
IANAP, but wouldn't confirmation of the existence of supersymmetric WIMPs not necessarily prove that they account for a large portion of dark matter?

EDIT: Not to imply that it wouldn't be a huge deal anyway.

simon_··on (x2-2.5x+1.5)/(x-1.5)
Maybe I'm missing something obvious, but I don't understand what that graph is trying to tell me. If the horizontal axis is x... what is the vertical axis? What does the shaded wedge represent? It certainly doesn't represent "x>1" in any way I'm familiar with. (A vertical line at x=1, with the space to the right shaded, I could see...)

Why can't Byron Cook make his own TeX package? I'm sure someone at Microsoft can help him with that...
simon_··on [dead]
The author seems to be totally clueless. In addition to seeming to claim that this guy invented subset and union notation ("U, or union, makes a new relation or set out of the relations or sets that are passed to it"), he/she completely misunderstands the halting problem.

"Computers occasionally hang on one line of code and fail to move on to the next, and no one can reliably predict when that will happen."

Seriously, Wired?

simon_··on Singularity movie is in production, co-director is Raymond Kurzweil
Right, and the next doubling will be even better (twice as good!). But the sense that we're right on the threshold of the infinite future has probably been around at least since industrialization.

For example, that bit about instant access to people and knowledge was probably said about the telegraph too.

simon_··on Singularity movie is in production, co-director is Raymond Kurzweil
Isn't a lot of the singularity idea based on flawed math? I always hear about and see graphs of exponential curves about to "go vertical", but... exponential curves definitely don't do that. You can zoom in on any point of e^x and it will look like it's about to have a singularity...

In more general terms... if ~technology has been getting better with some short doubling time for hundreds of years... why is it that the NEXT doubling is supposed to be the really significant one?

simon_··on Ask HN: Rate this Start Up - Venmo.com
Just curious: Do you eat the transaction fee if people fund their accounts with credit cards? If so... it seems like people might pay themselves thousands of dollars to rack up rewards at your expense.
simon_··on Finding the laws that govern us
As long as they're out to disrupt complacent information aggregation businesses, I hope they have Bloomberg and Reuters in their sights. Like Lexis and Westlaw, they reap enormous profits from providing structured access to mostly free information.
simon_··on Hackers on happiness & tiny houses, plus The Story of Stuff
I agree that there are serious problems with this article. Consider the statement:

"Our personal consumption in the U.S. is already in overdrive. It's now equal to 70% of our GDP (about double that of China and nearly a third more than that of Canada)."

This is a nonsense claim. GDP is defined as consumption + government spending + net exports. It doesn't seem obvious that increasing the relative share of government or exports would do anything for the environment.

simon_··on How to Drop Out
But not, apparently, built a house.
simon_··on Equity investing in superstar individuals (not their companies, them)
If it was structured correctly, you wouldn't take a tax haircut on the 250k. (You don't pay taxes on the proceeds when you get a loan, e.g.)
simon_··on Equity investing in superstar individuals (not their companies, them)
It seems like there would be serious problems in the enforcement of a contract like this. I don't see any reporting requirements imposed on the entrepreneur, and it's pretty unclear what a court would do in the event of a default on the entrepreneur's part.
simon_··on Garmin Ltd. - Google Finance
Marine and Aviation equipment together account for about 15% of Garmin's revenue. The overwhelming majority of their business comes from exactly the segment Android is targeting.
simon_··on New Google Music Service Launch
On the other hand, they've already had to get in bed with the music industry through their Youtube partnerships.
simon_··on Ask HN: What industry needs technical innovation?
How about law? Obviously there are non-technical problems there as well, but it seems like there is still a lot that could be done technologically to improve transparency and (maybe more interestingly) reduce expense.
simon_··on Nook, Barnes & Noble eBook Reader Announced
Looks like they took the overview page down... you can still see features here:

simon_··on Guide to getting started in Machine Learning
Andrew Ng's course notes are 90% of the way to being a textbook, and are an incredible resource, especially if you're going to watch the lectures.

simon_··on Wall Street Journal now the #1 selling US newspaper
Keep in mind that WSJ charges a substantial fee for online subscriptions, and probably ends up profiting more on them than on paper subscriptions.
simon_··on Elements Of Statistical Learning: now free pdf
several years ago, i took a class from prof tibshirani using this book and was absolutely blown away. if you don't have a deep stats background (as i didn't), you might find it scarily dense, but wow there's some good stuff in there.
