It's even tricker because there are a couple other doctoral law degrees that can be awarded in the United States (S.J.D. and LL.D.) that are much closer in spirit to the Ph.D., as they are research degrees. Although in fairness, in many cas

"Two or three redbulls" sounds a bit extreme to me but the principle itself is sound[1]. The idea is that a short nap helps you feel refreshed if you can keep it just that: a short nap. Caffeine also can help you keep alert, but it takes a

AFAIK, if you want to work with BLAS, LAPACK and friends you have to structure your matrices like this (as a big block of data) rather than pointers to pointers to pointers (ie a[i][j][k]). So even if there is some inefficiency in filling t

At the risk of hijacking the thread, since you are coding the same apps on multiple handheld platforms/languages, would you care to comment on which platform you enjoy developing in the most and why?

The problem of cold fingers and ears is solvable for more or less any reasonable climate-- certainly for northern Virgina. There are really excellent bike gloves and hats that can be worn under a bike helmet. Having a good pair of socks is

I wouldn't be surprised if this depends strongly on the individual in question. Some people are very good at "reclaiming" small chunks of time--15 minutes here and there--that add up over the course of a day. Other people have a much more d

This is very true. We should protect communication between citizens. I'd personally rather that we do this through protection of Internet communications. People don't send letters anymore, they send email (or tweets, or whatever). I'd be ha

What's the incentive for producing content that you can't control the distribution of (ie profit from)? edit: I mean from the perspectives of a producer, obviously the incentives of the artist are many.

Perhaps we should now define our terms very carefully, I am using the word consciousness to refer to the state of having a subjective experience. So states without a subjective experience-- sleep or anesthesia or death-- are unconscious. Do

Excellent points, especially the part about the constrained degrees of freedom in our actual interactions with the world. To give another example: the human hand has somewhere upwards of 20 degrees of freedom. Yet except in a few situations

Excellent points. Even sleep is problematic-- if I go to sleep and wake up after a nice nap, does the post-nap me share the same consciousness as the pre-nap me? Now while you were asleep I create a clone of you. Which one do you wake up as

Many things that seem intuitively clear turn out not to be true. I don't know if my "alien clone" would share a consciousness with me and you don't know either. It's not even clear if split brain patients (people with brain hemispheres that

Lack of access to fresh water is probably going to be one of the largest challenges of the 21st century. I don't think this is something to dismiss lightly.

The main thing, IMHO, was the way it used flash/flv for video presentation and had a way to let users upload fairly arbitrary video formats and convert to flv on the back-end. I don't remember if I encountered flv video independently before

Sorry, I mistyped. I meant that the additional amount of variance described by a more complex model beyond that described by a linear model is much less than that described by the linear model in the first place. Obviously the total amo

by joeyo 18y ago
I can't prove it, but I will assert without much fear of a counterexample, that, for most if not all systems, linear models describe most of the variance with the fewest number of free parameters. This may be as much as 90% in some cases, b

Public schools in the US are known to have uneven quality from state to state-- something that is perhaps unavoidable since each state sets its own standards, funding, etc. But why does school quality have to vary so much within a city/scho

Other than excel having some floating-point arithmetic problems, what difference does it make what tool he uses? Most things are linear to a first approximation anyway.

It sounds like you are arguing that science needs to be observational to be "real." I'd argue that science needs both observations and theory and that either half alone is incomplete. Think of the models as a manifestation of the theory. It

This is a really great point. I think many people buy homes because it is that thing they have to keep up with their neighbors/peers. On the other hand, owning your own property empowers you in ways that should not be discounted. To give si
