You make some interesting points. I'm not sure what the failure rate would have been if the Apollo program were allowed to continue with the same design (albeit better materials and engineering), but its probably incorrect to assume it wou

Well, I think the failure rate is somewhere around 60% not 5% (I think out of the 5 Falcon 1 launches, only 2 succeeded). But over time, that figure will go down dramatically as they perfect their model (hopefully). Anyways, if you really

You know, I had thought of that too, but I also thought the plane running out of fuel was the responsibility of the airline. I fly almost every other week, sometimes in quite terrible conditions that have warranted holding patterns and I h

It's interesting that after so many years they are actually going back to the old capsule design. I guess people are starting to realize that the Space Shuttle program may not have been actually worth it when you consider Saturn V's near 1

We've had real commercial access to orbit for over 20 years. The solution SpaceX is offering now however is to give companies (or god-forbid, individuals) a much cheaper ticket to space, albeit at a much lower probability of that cargo act

I have a slightly more pessimistic outlook on SpaceX, but I'll admit that I'm slightly biased. My dad has worked on the Delta, Atlas, and Titan rockets close to 30 years. These rockets are expensive (an order of magnitude more than SpaceX),

Obviously you can't predict these sorts of things. The question I have is how do these events affect FC's business? Did they notice a significant drop in app sales for the day? As a somewhat related aside, I recently had the displeasure o

10 years and still not profitable? yikes! Is this typical for non-software based companies?

Most of these (rather good) suggestions revolve around learning the theory of representing data. But how does one practically accomplish these visualization tasks? I have been delving in this area for the past couple months, and even thoug

This is a good read for those who just want a broad overview and working code for some interesting machine learning problems. It's not too realistic, but will get the ball rolling. For those who want to delve further, I would suggest read

I know exactly what you are talking about. When I first started my coursework in Machine Learning, I was given the freedom to use any programming language. But I simply defaulted to MatLAB because the rest of the CS department used it. I

I didn't get that feeling at all. It seemed like he referred to him as the "homeless man". Either way, I felt he focused more on the problem of A/B testing than making any denigrating comments about the homeless.

by physcab 17y ago
I am not sure if this is what you feel or not (and this may be over-analyzing), but for many people, homelessness is a problem that should be delegated for others to do something about. They don't like the presence of them in their neighbo

Aside from the user experience aspect, this sort of feedback would be very useful for developing receiver operating characteristic curves (ROC) where the false positive rate is plotted against the true positive rate--it's what I use to judg

I think people are missing the point of this article. The author isn't saying that people without math degrees should go out and try to be statisticians. What he's really saying is that anyone with the right mindset can do statistical anal

Are there any companies/non-profits/charities that would allow me to donate my gift cards that have a small balance on them but not enough to buy a product? Ideally I'd like to give this money to charity instead of throwing them away.

I don't think the author was applying an explanation either dumbly or trying to reduce its significance. I think it is part of our human nature to try and contain a tragedy by labeling or attributing some cause to it. I'm not a therapist,

This article was disappointing. I was expecting slightly more in-depth analysis into the workings of Craigslist and instead I got a rant about Newspaper websites.
