kmcgivney··on Chatroulette + GeoIP + screengrabs = Chatroulette Map
Relatively popular on the border of Nunavut and Manitoba though.
kmcgivney··on How Education is Ruining Your Life
Towards the end of the article, he reaches a conclusion about the importance of regional self-sufficiency which I don't understand at all. Firstly, because it has seemingly no connection to anything he was writing about. Secondly, because it contradicts basic economics of comparative advantage.
kmcgivney··on Former gang member turns entrepreneur... by giving tours of LA gangs
This reminds me somewhat of the tours they give around Belfast, showcasing the murals in the Catholic and Protestant neighborhoods.
kmcgivney··on Review of Let over Lambda by Doug Hoyte
This book is a little controversial among lispers. There was a discussion about it recently on c.l.l.

http://groups.google.com/group/comp.lang.lisp/browse_frm/thr...

I'm thinking about reading it. Some people don't like the editing, since it's self-published and doesn't have a lot of polish. It's also pretty heavy on the author's opinions (which might not be a bad thing).

kmcgivney··on Welcome to HN: A refresher course on how to disagree... (2008)
I suppose someone out there disagrees with you.
kmcgivney··on Welcome to HN: A refresher course on how to disagree... (2008)
In this case, that would be "DH3" according to the article. Contradiction with no supporting evidence.
kmcgivney··on Insurgents Hack U.S. Drones
A bit of a nitpick, but no stealth bomber has ever been shot down. That was a stealth fighter.
kmcgivney··on I'm turning into a Lisp snob
Nice troll. Isn't Hacker News written in lisp?

EDIT: HN is written in Arc. You're saying that there's "little you can usefully do with LISP" on a site which was written in lisp.

kmcgivney··on Good Knuth, Bad Knuth
I didn't like the butnth. I get an allergic reaction to append. Blame Ken Tilton.

  (defun shuffle-in-place (l)
    (cond ((null l) nil)
          (t (rotatef (nth 0 l)
                      (nth (random (length l)) l))
             (shuffle-in-place (rest l))))
    l)

  (defun shuffle (l)
    (shuffle-in-place (copy-list l)))
kmcgivney··on The Ultimate Failure of Moneyball
You are right. The Sabermetrics used in baseball by teams like the A's gave them an advantage over their competitors in 2000, but it would be crazy to think Theo Epstein and Brian Cashman haven't read Bill James.

However, I think your example is "cherry-picked" in iteself. The Rays finished only third this year, and in their whole 12 year history finished in dead last 9 times... mainly because they did not have the money to compete.

kmcgivney··on Your Race Affects Whether People Write You Back (WRT Online Dating)
In the article, the most staggering bias was white women's preference for white men, but also the general preference of women towards white men.

Given that these stats are coming from the USA, I think our culture - television, movies, etc - provides us with ample images of white males in positions of success and power. Maybe this sways women's perceptions?

kmcgivney··on Intel to port Silverlight to Linux
Too late. MLB.com, the only site I cared about using Silverlight, dropped it last year in favor of Flash.
kmcgivney··on Steve Yegge: Lisp is not an acceptable Lisp. (2006)
I am particularly amused by this guy's ranting about hygiene and macros. I have written quite a bit of lisp, and debugged plenty of macros, and once you have some experience with gensyms you really don't look back and wish there was a hygienic system.
kmcgivney··on Steve Yegge: Lisp is not an acceptable Lisp. (2006)
The OP was a followup to the article you cited. Is that what you meant to say?
kmcgivney··on Whoa, this is heavy: brain equates weight with importance
I've noticed this with chess pieces. Play on a cheap unweighted plastic set, it feels a lot different than playing on a heavily weighted one.
kmcgivney··on ATT dumps Kevin Mitnick
That's the kind of password an idiot would have on his luggage!
kmcgivney··on Bad Design in Star Wars
How about those AT-ATs the empire used on Hoth? All you need is some rope and they fall over?
kmcgivney··on Jerks actually reduce the risk of traffic jams
That's a really good article.
kmcgivney··on Jerks actually reduce the risk of traffic jams
That conclusion is a weakly implied by the research (at least the way it was explained), which was based on "a computer model of how a crowd of people move across a confined space".

They did not clarify how it applied to car-traffic. For instance, people react very differently to minor collisions while walking versus driving. I'm just guessing here, but I would think the simulation does not account for complicated behavioral factors (e.g. some people, when cut off, may overrreact when hitting their brakes, thus causing more traffic behind them).

kmcgivney··on Ask HN: Does this concern anyone else?
Maybe he is concerned about the relative popularity of HN in Kyrgyzstan?
kmcgivney··on Why are there no Googles, Microsofts, Twitters, Facebooks etc from UK?
While you are correct that the population of the USA is around 300 million, the population of the UK is roughly 60 million. Of course both numbers are presumably more than the "target" you are talking about, but I think it's safe to say that Great Britain is about 20% of the size of the USA.

Also, I don't understand the growth-rate math. Why would the UK company have 1/100th the number of users?

How much would the variety of English you use on a website alter your traffic? I'm asking because I really don't know. Does anyone have research on this?

kmcgivney··on Shrink a quarter to the size of a dime
OK, so I'm wondering how fast would the quarter have to travel to actually shrink to the size of a dime, based on special relativity?
kmcgivney··on Decimal expansion of 1/89 is Fibonacci sequence added together in a simple way.
I think it's simpler to go this route:

If S is the sum of f(i)10^(-(i+1)), then you could break up that sum into two other sums (using the fibonacci relationship), express them in terms of S, and solve.

I get S = (1/100)S + (1/10)S + .01
