    Is it just me, or is the comment section all about hating on MBAs, when the article is about how these elite programs are losing out due to changes in US immigration policies?

    If you want to avoid this, just read the paper. I don't understand why technical people waste their time complaining about this stuff. We all have the acumen to read, understand, a…

    For those looking for their motivations, here it is (recall PG&E filed chapter 11 to navigate liability payments): "Second, any catastrophic wildfires caused by PG&E this year coul…

    No, it works because it (very likely) stimulates a very specific kind of brain activity that leads the body to break up the proteins. The article's explanation is incorrect. The ex…

    Yes, I do think that a gap in weapons technology is meaningful. I love numbers so let's talk about those using the Iraq war as an example. Here's an estimate of the number of casua…

    The fact is that the dictator would still win. The rebellious citizenry would live a life of absolute misery, just as those in the middle east do. The 2nd amendment made a lot of s…

    I don't really believe this. One of the major advantages of real cameras is the sensor size. More sensor size gives you more SNR / dynamic range. All of the tricks used in a smartp…
