vertak··on Mathematics and Computation [pdf]
This along with Scott Aaronson's (https://www.scottaaronson.com/blog/) make for good reading on the theory of computation.
vertak··on Maya ritual cave ‘untouched’ for 1k years stuns archaeologists
@ianai you should give the book 1491 a read, it is likely exactly what you're looking for and a well written book:

vertak··on The Functional Programmer – Keeping Repetitive Strain Injury at Bay [video]
For personal health at the office, I think the biggest bang for your buck is to buy a water bottle that takes minimal effort to drink from (I’ve found those green sport Gatorade water bottles are prime) and sip continuously throughout the day. You will feel amazing from all the H2O alone. You will be forced to get out of your seat multiple times a day to visit the restroom. You will will get more facetime with people in your office from walking more. And walking more gives you more opportunities to fill up your water bottle. The virtuous cycle!
vertak··on Hiring without whiteboards
I work remotely and sometimes interview new potential hires. Does anyone have some suggestions for how I could imitate whiteboard questions without actually having a marker and surface available to me or the candidate? It's a little awkward to ask them to write on a piece of paper and angle their camera so I can see what they're writing! Is there any good software that can emulate this?
vertak··on The New Atomic Age We Need
0 people have died in the US as a result nuclear power. Chernobyl failed because its operators turned off the emergency failsafe system in order to do a test of the reactor, which was also botched. Look up the Linear no-threshold model of radiation. There's no statistically significant evidence that radiation exposure of even 1000 millirem (average US dosage is 360 millrem, and 2/3rds of that is from natural radiation such as the sun and rocks) has negative health effects.

Also what do you even mean by "the source of error is infinite"? All of those sources of error apply to coal and gas plants, except that nuclear power plants are so much more tightly regulated and protected that these "sources of error" are far more likely to affect coal/gas plants than nuclear.

Check out this information where they crash an F-4 into 10 feet of concrete, reducing the F-4 to dust. Nuclear power reactor containment shields have more than 10 feet of concrete, and even so have procedures for automatic shutdown of the fission process that don't rely on electricity (eg gravity).

FUD such as this is a large part of why we do not have fission today.

vertak··on Reverse-engineering the Kayak app with mitmproxy
Does anyone know the possible legal repercussions open-sourcing a web service's API when the company doesn't explicitly grant permission? This is really neat, but could also raise the ire of a service that doesn't offer an API for a reason.
vertak··on Show HN: iPhone app to fight or pay parking tickets
How does the app gather information about your outstanding tickets? Do you have to input them by hand? Does it scrape some public database, and if so do we have to wait for you to add our city in order for us to use it?
vertak··on Show HN: Never lose a website again
Is each user's index stored somewhere in their browser or on your servers? It would probably ease peoples' minds if they knew their history was stored locally, but I can see the performance hit that might make.
vertak··on Why I’m No Longer a Professor
If the universities are smart and look at the MOOC's not as a competitor but as a partner, then higher-ed can improve. I'm a college student now and one of our school's math classes experimented with flipped teaching. I think the emergence of MOOC's is what largely caused this my school's faculty to seriously consider the meter of online learning, to the point where they were willing to A/B test a required differential equations class. While the first results from MOOC's haven't been what people expected, http://chronicle.com/blogs/wiredcampus/from-a-million-mooc-u... At least, like one of the comments above said, they're making the established higher ed organizations rethink their practices.
