I believe that the paper argues that this is one of those cases where approximations are not good enough. You cannot read RSA encrypted email with approximate factorization algorithms. You can't forge a document and fool anyone with an

Well I was asking about the employees not founders - it seems that working for a startup exposes you to the downside risk without paying out in the event of a win (except of course for the miraculous event of an IPO). Do the employees all

So what's left? Is working in someone else's startup a way of "paying dues" to get connected with people necessary to form your own? Suppose that people believe that working for someone else's small company will get them connections to f

If anyone is interested in what a real "machine learning" approach the problem of learning a ranking function from data looks like see this paper: Burges et. al. Learning to Rank using Gradient Descent http://research.microsoft.com/apps/pu

Someone mentioned this the other day, but I don't think it was ever given a satisfactory answer - is it really worth it to work for a tiny company that will likely crash? Does the expected payoff from the tiny equity share justify the inse

This is great but I must know: does stackexchange allow automatic rendering of latex formulas like wordpress? If not then I think this one is going to have a hard time taking off.

I spent a month in iceland this summer and it is an amazing place. Beautiful landscapes, long nights in the winter/days in the summer, and it's sparsely populated. I'm not sure how great of an idea it is to put a bunch of data centers the

I strongly disagree - I don't think any fields - even perpetual motion machine construction or astrology - are inherently bogus. We should demand that these fields make falsifiable predictions and then test them to find out which ones ar

Not sure what you mean by fixed-criterion How about about just demanding falsifiable predictions, and doing experiments to test them?

I see - thanks for the info. I didn't know the background of the author or recognize the reference. I'm going to read this one over much more carefully.

Yeah I think you're totally right on here. I would go even further and suggest that these pseudo-scientific valuation models were cynically exploited to make it sound like the risks were calculable. I think an analogy to medicine is approp

I know that prof. Appel is a really smart guy from reading his books on optimizing compilers - so I'm going to risk looking like an idiot here, especially because I don't have time to carefully read the paper.. but maybe someone can help me

This type of language can be confusing. It is not a "real" magnetic monopole but an "emergent" one. The collective behavior of all of the spins in the material shows the experimental signatures of a magnetic monopole. The idea is pretty

please share your experience! I don't take this ranking wankery too seriously. There are some papers that I really love that were published is lesser known journals. I guess I was talking about AMO and cond.mat. which are the majority of

The journal rankings for physics appear to be bogus. 1. Rev Mod Phys 2. Mat Sci Eng R 3. Annu Rev Phys Chem 4. Phys Rep 5. Rep Prog Phys 6. Nano Lett 7. Prog Polym Sci 8. Adv Mater 9. Phys Rev Lett 10. Adv Polym Sci Most agree that the top

Okay I understand where you're coming from. I'm really curious though, what were some of the bugs that showed up? Were they easy to fix or did they require adding a lot of special cases and patchwork to the code?

This sounds like a bad idea to me if taken too seriously. Makefiles come from a grammar not a 5th order markov process. The sampled strings from the markov chain are not likely to be representative of the makefiles encountered in practice.

Well I can't comment on the quality of the calculations he's talking about - but even the previous estimates of the power consumption of the brain were awe inspiring. The power consumption and stability against things like epilepsy are an

Okay let's fantasize that the staff of NASA was willing to work for $1 / year - and that the cost per kg of sending stuff in to space converges to the energy cost of the chemical rocket fuel. I suspect that space flight is still pretty damn

I always thought it was partial dehydration that caused the early waking after drink - Is there anything else. I haven't really looked into it, just curious.

Well I'm not sure how dangerous it really is to drink booze while gravid, but it's one form of self-experimentation I wouldn't recommend. There's plenty of real experimentation establishing the risk of things like fetal alcohol syndrome

anecdotal counterpoint: Last night was a session of midnight gluttony. I ate a 12" pizza, an order of fried calamari, lots of miscellaneous finger food, four beers and two mojitos. I was asleep about 2:30 am and awoke about 6 am. I dran

For anyone interested in this I recommend the really great "What makes airplanes fly" by Peter P Wegener. http://www.amazon.com/What-Makes-Airplanes-Peter-Wegener/dp/... This book was part of a course he taught for non aerospace engineers
