Today I Learned:
1) I actually learned this on Monday, but it’s useful enough to cheat with — you can run “make” using more than one core with the -j flag! So if you have a 4-core machine, you can run “make -j 4” to build your program four times as quickly!
2) It takes between 4 and 8 hours to etch microfluidic channels into a set (2-4(?)) of typical glass slides.
3) I knew that Genghis Khan had a lot of descendants. Thanks to Chris Lennox, I now know that he had a lot of *direct* descendants — specifically, about 10% of the population of Asia, which is *way* more than can be accounted for even by his stunningly large collection of wives. Evolutionary biologists studying the Genghis Khan haplotype hypothesize that simply being a descendent of the Khan has been culturally selected for over the last 800 years.
