That book you read was Russell and Norvig, it's one of the best textbooks ever written on any subject: http://aima.cs.berkeley.edu/

Yes, I read the article and I applied an idea I took from one of the first articles on Nate Silver's 538 'news' site [0] of using Bayesian statistics to decode news as you read it and in my opinion the data presented is very

It actually doesn't even provide data for two cities, just one. It talks about anecdotal data that is the equivalent of hearsay: "we consistently hear from our riders in Chicago and elsewhere."

I don't really buy it. What if DUI rates fell across all cities nationwide, regardless of Uber being on the market?

I wholly agree with this article. The exact point the author is getting at is something that I have been trying to say, but rather inarticulately (probably because I didn't actually go out and survey people and define "what is pr

I find this sentence very weirdly written from a stat viewpoint and not helpful at all to the "average" reader. >>>>About one in 14 tech workers is black or Latino both in the Silicon Valley and nationally. Blacks and

People will look back upon this date with utter lament because the world of lambdas has been unleashed upon a much more dangerous and wider world of programmers.

You realize the same exact thing could be said about video game designers, right?

There is also a complete lack of tests. It'd be nice if there was a library of tests for all sorting algorithms. I'm sure there is, but something more widely accepted and well known.

There already are a pair of data-driven journalists at the WSJ whose day-to-day sounds more like a data scientist than a typical journalist. They are Tom McGinty and Rob Barry. They gave a great talk recently, which I wrote about (shameles

The demotivation poster (we'll ask for estimates, but then treat them as deadlines) really strikes a chord because that is one of my major 'gripes' with the agile planning process. Particularly when a manager is heavily invo

Thanks @acoustic, it's always nice to see bunk-busting. Just looking at the quote makes the statistic sounds hard to believe. Did the story include drop-outs like Bill Gates and Mark Zuckerberg?

Until I see hard data supporting one way or another, it's all bunk and personal anecdote. Though I will comment and say I do like the one about "just show up" rather than waiting for being in the mood.

Actually, robot traffic accounts for a much larger share of traffic for any of the big websites than you think.

Wasn't criticizing the sale at all (edited to clarify tone), just found it interestingly related. I use it myself, but not sure about the 5 years wager. One of the main reasons quite a few people I know use it is precisely because it

NYTimes actually pointed out another curiously-related Tweet [0] from the other co-founder, Jan Koum: "totally agree with Vinod Khosla. people starting companies for a quick sale are a disgrace to the valley... 3:47 AM - 17 Jul 2012&qu

I welcome the change and think it is a good solution. I'm surprised this hasn't been mentioned yet, especially for the HN crowd, but it's relatively easy for any developer to write a bot to auto-register them-self. One could

Just another thought, I have grown to completely mistrust any 'well-used' rating service and thus must say Uber and the like has a long way to go before I will trust their ratings by one iota. I remember a friend once opened up a

Interesting post, however I have two things to bring up. 1) The author works at Union Square Ventures, which has a vested interest in '2.0' regulation. A quick search shows that although it might not be directly related to Uber,

But if that is displayed as a line chart, that clearly displays the year-over-year differences. So if someone wants to ask "what is the overall trend of spending over the past five years?" that is nearly impossible with the p

Seriously? Startup time as a deal-breaker for using this? What about other, much more important and relevant metrics? If you have to spend 23 seconds but save, let's suppose, thirty minutes with faster development and runtime, isn&#

My favorite rule is 4.1.1; always use braces even where optional. I think a small fraction of the economy may have been damaged by the bugs caused by the silliness of leaving out optional braces and then having another developer come along

Yes, that's exactly why, because the FCC said to do it that way. There are countless examples of "why is it this way" being answered "because that is what some arbitrary person picked." My favorite example of this

To be honest, I'm shocked this is on the front page as this website has been out for years and already notably mentioned, but I guess it's good to recycle very important websites for those who haven't heard of it. My favorite

By the way, this is written by the sixth-place winner of last year's Kaggle Competition for detecting Whales. [1] I think another very interesting point brought up was when that even such a well-ranked model on Kaggle did a poor job w

Last time I checked this was Hacker News, not Reddit, and I am getting sick of articles like this making it to the front page (as I am aware other commenters have noted). I didn't even need to click on the article (but did in a vain ho
