Depending on how you structure your loops, things can be optimized on how it hits the cache and reads contiguous memory addresses.
warrenmar··on Markov Chain Monte Carlo for Bayesian Inference – The Metropolis Algorithm
Not to hijack this post, but I'm saddened every time I see anything monte carlo related referred to as the metropolis algorithm. When you're the boss, what you say goes.

warrenmar··on Slackware 14.2 release candidate 1
For those of you that don't know about Slackware. Slackware is the oldest distro and it is still plenty alive today. When to setup linux on my computer in the early days with other distros (red hat/suse/etc), this would eventually crap up (rpm hell) and give me something unusable. Using Slackware forces you understand how everything works in a linux distro. This lets you fix your own problems.

warrenmar··on The Refragmentation
The Economist has a four paragraph summary of the book.

http://www.economist.com/blogs/economist-explains/2014/05/ec...

Low growth causes more income to come from capital, which causes more inequality due to inheritance and the rich getting richer. The solution is a global progressive tax on capital.

warrenmar··on Theranos Wellness Centers Aren’t Using “Nanotainers” at This Time
There's a paper in the Clinical Chemistry and Laboratory Medicine journal titled, "Theranos phenomenon: promises and fallacies" [1]. It says most of the cost are related to overhead and personnel, not technology. Consumables are cheap. Also it is entirely possible that tests are being subsidized with VC money currently. I don't know what they would have to charge to be cash flow positive.

warrenmar··on Pythagorean cup
This principle is used in aquaponics in the form of a bell siphon. You don't want to keep the roots of your plans submerged for long periods of time, so this lets you flush out the water automatically.
warrenmar··on Analysis of Over 2,000 Computer Science Professors at Top Universities
"weaker" metrics can be useful, because you can understand it better. If I tell you a PageRank of an author is 3.452. That means nothing to me. If I tell you somebody's h-index is 18. That means they published 18 papers that got 18 citations each. The h-index is useful for comparing people in the same field. There is also a metric for journals called impact factor.

warrenmar··on Analysis of Over 2,000 Computer Science Professors at Top Universities
The original funding Larry got was from the Digital Library Initiative. Then the web blew up. Maybe I shouldn't say PageRank was designed for citations, but that is where it draws its influence from. Things don't magically pop out of no where. But if you look at the PageRank algorithm, it looks like it is designed for paper citations. As a graduate student, you start a some place and you end up at a different place from where you intended to end up.

My point is that one shouldn't be surprised to see that PageRank would work well for paper citations.
