Where to wait for an elevator

http://www.johndcook.com/blog/2010/11/29/where-to-wait-for-an-elevator

John D. Cook. Where to wait for an elevator. Imagine a bank of three elevators along a wall. The elevators are in a straight line but they are not evenly spaced. Where do you stand in order to minimize the expected distance you’ll need to walk to catch the first elevator that arrives? This scenario comes from the opening paragraph of a paper. Distance and that the minimal average distance to the elevator is in fact achieved by standing at the median. This problem illustrates three optimization theorems:.

K-Nearest Neighbors: dangerously simple | mathbabe

https://mathbabe.org/2013/04/04/k-nearest-neighbors-dangerously-simple

Exploring and venting about quantitative issues. K-Nearest Neighbors: dangerously simple. K-Nearest Neighbors: dangerously simple. April 4, 2013. Cathy O'Neil, mathbabe. After all, a good data scientist is hard to find. I’m here to say, it’s not clear that’s possible. Even the simplest algorithm, like k-Nearest Neighbor (k-NN), can be naively misused by someone who doesn’t understand it well. Let me explain. Holy shit, that was simple! Mathbabe, what’s your problem? The devil is all in the detail of.

Attaboy - A political map of Canada

http://attaboy.ca/archives/2011/04/001067.php

April 5, 2011 at 10 PM. A political map of Canada. In countries whose politicians are elected to represent regions or districts, elections are times of maps, maps and more maps. In the USA, Canada and the UK, geographical maps are the most common visualization tool for predicting and showing electoral results. This isn’t surprising since national and regional maps are immediately familiar to people, and therefore have a low barrier to comprehension. 8220;A cartogram is a map in which some thematic mappin...

Kaffee und: [Kuchen]: Magnificent Moscow

http://blog.fitzell.ca/2014/05/magnificent-moscow.html

Monday, 19 May 2014. Day 49 - Moscow - 17,160 km travelled. Moscow has been awesome. I think we both expected to like it but were expecting it to be quite grey, bleak and dramatic more in a post-Soviet kind of way. In fact, it's a really beautiful city with a vibrant cafe culture, lots of lovely parks, and amazing architecture on top of the cathedrals and museums it's famous for. For me, our few days here have been one of the highlights of our trip. Yes, next door! Subscribe to: Post Comments (Atom).

Kaffee und: [Kuchen]: June 2010

http://blog.fitzell.ca/2010_06_01_archive.html

Friday, 25 June 2010. The Trouble with Twitter. The thing about Twitter is it's so easy. Sitting down to write a blog post takes time and effort. I want to develop a thesis, establish a reasonable structure, and edit the thing until it flows and becomes a pleasure to read. Ignoring the time spent in advance thinking about the topic, a well-written non-trivial blog post might take me an hour to write ( some. Throwing out undeveloped thoughts with everyone else.

Kaffee und: [Kuchen]: July 2010

http://blog.fitzell.ca/2010_07_01_archive.html

Friday, 9 July 2010. Off to the races. It was fun though with everyone in their posh summer dresses, running back and forth from the track to the tables to the betting windows. And we even managed to win enough to just about cover admission, food, and drinks. Not bad for an evening's entertainment. So of course, now that I have a fool-proof guaranteed system. We're going to have to head back more often to capitalize on it. Or. maybe I should quite while I'm ahead. Links to this post. Friday, 2 July 2010.

Kaffee und: [Kuchen]: The long train west, part 2

http://blog.fitzell.ca/2014/05/the-long-train-west-part-2.html

Thursday, 15 May 2014. The long train west, part 2. Day 45, 8:00 am local time - Train 81, 1,419 km from Moscow - 15,894. I haven't a clue where we are. All seemed good at about 3:00 this morning when we stopped in what was presumably Yekaterinburg, though we were awoken there by someone trying to open our compartment door and thought our days of privacy might be over. They seemed to quickly move on to the next compartment, however, and the train carried on into the night. They had an English menu, but i...

Kaffee und: [Kuchen]: The long train west

http://blog.fitzell.ca/2014/05/day-44-1120-am-local-time-train-81-3006.html

Wednesday, 14 May 2014. The long train west. 44, 11:20 am. Time - Train 81, 3,006 km from. We left Irkutsk at 1:17 am local time yesterday, though the clocks in the train station all said 20:17 because all trains in Russia run on Moscow time. This is particularly confusing when, as in our case, the time change spans midnight and you need to book the train for a different date than your actual departure. Subscribe to: Post Comments (Atom).

Kaffee und: [Kuchen]: When to use a Seaside Component?

http://blog.fitzell.ca/2009/05/when-to-use-seaside-component.html

Friday, 8 May 2009. When to use a Seaside Component? A recent StackOverflow question. Asked "When to use Seaside components, and when to use simple render objects? This is a common challenge for new Seaside users (with the additional wrinkle of whether they should be implement a Brush thrown in for extra confusion). While we're on the topic, asking. And answering Seaside questions. Might help gain us some exposure and legitimacy. I actively monitor the RSS feed for Seaside questions. Up to a new class.
