   Very cool! One minor nitpick -- the author mentions that this is 'completely unsupervised'. It's true that the author didn't need to manually classify the data, but someone did. So, I believe that this is actually superv

   "Entitlement spending" is a fairly common term used to describe government spending that benefits the people directly. I've seen it used in all kinds of places. I haven't heard it used in a derogatory way, though maybe I

   I think the big deal comes when lower-class teens work to help support their families. The fact that work doesn't matter to admissions officers only exacerbates their disadvantage.

   We are very mindful of overfitting our models, and very skeptical of backtests on their own. Successful strategies often have some fundamental theory about why they should work. If not, the backtest needs to be very robust, and demonstrate

    Hence the common syntax: "mobile virtual network operator (MVNO)" I really don't see the downside of not expanding it once, unless you're trying to avoid educating people.

    Yeah, that's a problem I'm still working on solving. Initially, I had planned to wire through the basement, but getting through the floor turned out to be a littler more difficult than I had hoped. At the moment, the wires are run

    Thanks! I'm using pandas as well, though haven't got too far into the quantitative analysis just yet. I hadn't heard of InfluxDB before, looks interesting.

    Cool! I'm doing something similar, but more from the data-analysis side of things for my condo's efficiency. I've been trying to keep a blog of my progress, if anyone is interested, though please forgive the poor grammar &#x2

    My understanding is that this is a straight-up bad law. It provides no realistic benefits and may actually harm US security interests. This passed because no congressman wanted to appear to stand against 9/11 families during election s

    Well, for one, supply & demand says you would sell more of the gadget if it was priced lower. If not, you'd keep it the same price and enjoy wider margins.

    Does this mean that the electrons experience infinite acceleration? I know very little about graphene, but this seems to violate some basic laws of physics. Do the electrons actually behave this way? Or is this description of constant veloc
