Crossword Butler

I am pleased to announce the launch of Crossword Butler v. 2.0 (let’s call it beta 1). Those of you who remember the original Crossword Butler will notice some differences from the old version, namely:

1. It is now an online interface, accessible at http://crosswordbutler.com
2. It doesn’t blindly get all available crosswords; only the ones from providers who have given their permission
3. Most interestingly (I think), it gives independent crossword constructors a site to host their puzzles and distribute them easily for free or for profit.

Right now the site is essentially a souped-up puzzle pointers page, that in addition to most of the standard links, also links to puzzles like Matt Gaffney’s weekly contest and Andrew Ries’s weekly Rows Garden puzzle. But the fun part will begin when independent constructors start using the site to host their puzzles. Right now there isn’t a one-stop shopping destination for independent puzzlemakers, so constructors have to set up Paypal accounts, websites, e-mail lists, etc. to be able to distribute their work. Crossword Butler will take care of all of that; all a constructor has to do is upload the puzzles to the site (through a simple interface). If the puzzle is paid, I would take a (small) cut; if the puzzle is free I’ll happily host it free of charge.

Feel free to become a member of the site and poke around. If you have suggestions, comments, questions, leave a comment below!

Thanks for reading. This is my grand experiment this year — hope it works.

Ben Sheets vs. Barry Zito

When I read Moneyball a while back, it was already a few years old, and already seemed it (a whole chapter devoted to Scott Hatteberg?!) I don’t remember all of it, but one part in particular stood out for me at the time:

The hardest thing,” says Billy [Beane], “is there is a certain pride, or lack of pride, required to do this right. You take a guy high no one else likes and it makes you uncomfortable. But I mean, really, who gives a f**k where guys are taken? Remember Zito? Everyone said we were nuts to take Zito with the ninth pick of the draft. And we knew everyone was going to say that. One f**king month later it’s clear we kicked everyone’s ass.

…

A lot of people in the room have forgotten that the scouting department hadn’t wanted to take Barry Zito because Barry Zito threw an 88-mph fastball. They preferred a flamethrower named Ben Sheets. “Billy [Beane] made us take Zito,” Bogie [a scout] later confesses.

Well, now that both guys’ careers are essentially over, we can ask the question: who had the better career, Zito or Sheets? Did Billy really kick everyone’s ass with that pick? Or were the scouts right?

“Improved” Rock-paper,-scissors

I don’t know about you, but growing up I always played rock-paper-scissors with just three weapons … you know, the three in the title. But my wife is French, and as Wikipedia explains:

Similarly, the French game “pierre, papier, ciseaux, puits” (stone, paper, scissors, well) is unbalanced; both the rock and scissors fall in the well and lose to it, while paper covers both rock and well. This means two “weapons”, well and paper, can defeat two moves, while the last two weapons can only defeat one of the other three choices.

So I have questions for you.

1. There is a weapon in the French version that should never be used (in an optimal strategy). Which one is it and why?

2. Is it possible to add one weapon to rock-paper-scissors without rendering one weapon inferior to all the others? If so, give an example; if not, show why not. (Fans of The Big Bang Theory know it’s possible to add two.)

Solving the overtime dilemma

The NFL has an overtime problem, or so everyone seems to think. Every year we get long screeds from columnists lamenting the unfairness of sudden death overtime. Why? Some people think it’s unfair that one team can get the ball and score, without the other team’s offense ever taking the field. Others point to the fact that the team that wins the toss wins the game 25% more often than the team that loses the toss. And recently, the NFL has taken some action, changing the rules for overtime in the postseason:

Under new NFL overtime rules, a coin toss still determines which team gets possession of the ball first in the overtime period. However, if a team scores only a field goal on the ensuing possession, the opposing team has the opportunity to possess the ball. Thus “sudden death” applies only to touchdowns, not field goals. If the score is still tied after 15 minutes, play continues until a score is made and a winner is determined.

Okay, a few things here. First: the new overtime rule for the playoffs seems overly complicated and doesn’t completely solve the problem of only one team touching the ball. Second, in the regular season, what’s so bad about ending a game in a tie? Why not eliminate overtime completely in the regular season? Well … that’s not going to happen. We hate ties here in America. So with that in mind, here are my two cents about “fixing” overtime.

A fun math problem

When I was sick recently, my boss e-mailed me a math problem he said I might try to solve to pass the time. Now, I had thought that this was a problem he had read somewhere, but no: this is an actual thing that happened to him. It happens to lend itself to a cool problem, and here it is:

You have ten players and five two-player games at a party. There will be five rounds of games, and each round will include all five games played simultaneously. You want every player to play each game once, and never play against the same player more than once. Is there a solution?

Once you’ve worked that out, consider:
(a) Is there a solution if you have N rounds of games and 2N people, where N is an arbitrary odd number?
(b) Is there a solution to (a) if N is even?

I know the answer to (a). I suspect I know it for (b) but I can’t prove it. I’d like to see what you all can come up with.

UPDATE 11/14/2011 This problem has been completely solved in the comments! Check them out.

UPDATE 2: 11/15/2011 I’ve also put the C++ code I used to brute-force a solution in the N=6 case online here, in case anyone’s interested.

2201 Fascinating “Facts”

When I was a wee trivia buff, I received a book called “2201 Fascinating Facts.” In fact, if I remember correctly, I actually received *two* copies of it within the span of a year or so. And I loved it. I read it several times in my youth and learned lots of wonderful facts. But in the internet age, you actually get to learn what is a fact and what is not, thanks to Snopes and the invaluable List of Common Misconceptions page on Wikipedia. And since that time, I have learned that A LOT of the “facts” in the book are not so. Such things include:

The Great Wall of China is the only manmade structure visible from space (debunking)
You can see the stars in daytime from the bottom of a well (debunking)
The deer botfly can travel more than 800 miles per hour (debunking)

And the one that brought all this back to mind: a duck’s quack doesn’t echo (debunking). So now I’m totally skeptical of anything and everything I’ve read in that book. Here’s what I’m going to do: I’m going to start reading it again to (a) brush up on my trivia knowledge and (b) brush away all the false facts I’ve learned by researching any claims that seem suspect.

A first one that has always seemed suspect to me: there is a claim that some royal figure described St. Paul’s cathedral as “awful and artificial” — meaning it as a compliment! Supposedly, “awful” meant “awe-inspiring” and “artificial” meant “full of great art.” This is actually retold in several places including some that inspire confidence, but no one seems sure of its accuracy and there doesn’t seem to be an official debunking (or, um, bunking). Can anyone find anything about that?

All right, this blog is going to start detailing my journey. There may not be as many mistakes as I think there are, but I have to know. And you’re all coming along for the ride.

Star Wars Thoughts

When Alderaan exploded, did Obi-Wan Kenobi feel it instantaneously or was there a speed-of-light delay?*
Yoda says “Always two Sith there are. No more, no less.”

So why did the Jedi think the Sith had been extinct for a thousand years?
Who are the two Sith after Darth Vader and Darth Sidious both die in the Death Star?

Han Solo boasts that the Millenium Falcon made the Kessel Run in under twelve parsecs.

People have pointed out that this is a unit of distance, not time, but aren’t they equivalent according to relativity? Since there’s no real way to time a run that long, couldn’t someone have checked the Falcon’s odometer after the run to see how long it took him?
Or, more likely … is Solo just lying to con Luke and Obi-Wan?

Finally and most importantly … what changes in the prequels if Qui-Gon never finds Anakin? Dooku doesn’t get killed by Anakin so presumably he remains Sidious’s apprentice. The Jedi still get exterminated and Palpatine still takes control of the Senate and becomes emperor. The Death Star is still built with Dooku taking the role of Darth Vader. The main events that never happen are Luke and Leia being born and Naboo being saved. I guess my point is … all the bad things still happen if Anakin is never found, but none of the good things in the original trilogy ever happen. Finding Anakin wasn’t a bad thing for the Jedi; it saved them.

* This joke is lifted from my Twitter feed, and was probably unintentionally stolen from XKCD. Eh, still funny.

Cute segment, Kristen Schaal is great, etc. But at the end, they list a phone number, 1-800-555-VAJJ. No problem, right? 555-numbers don’t go anywhere, do they? Well, not exactly. Most 555-numbers are reserved, but 800-555 numbers are not. There is one that is reserved for TV shows and movies — 1-800-555-0199. Look for it; it’s everywhere. However, if you don’t use that number, you risk sending callers to a number that promises “sexy students, housewives, and working girls” … like the one listed by The Daily Show does. Honestly, where did you think dialing 1-800-555-VAJJ was going to get you?

The problem with Twitter

… is that 140 characters isn’t always enough to say what you want. Here’s a case in point.

A common trick question goes as follows: who was the last switch hitter to be the American League MVP? In the National League there have been a couple recently — Jimmy Rollins and Chipper Jones come to mind — but there hasn’t been one in the AL for a long time. The intended answer for the question is Vida Blue, who won the AL MVP in 1971 … but of course, he was a pitcher, and had all of 121 plate appearances that year (this is before the DH). So it’s a trick question, and I’m not a big fan of it. So when Doug Glanville posted the question (retweeted by Joe Posnanski), I wrote:

Oh yeah? Eck [Dennis Eckersley] was a switch-hitter in 1992 too. (Prove me wrong!)

I thought it was clear that I was joking — the joke being that Dennis Eckersley did not bat at all during his 1992 MVP season, being a pitcher in the American League, so who knows if he decided to switch-hit that year? But apparently no one got the joke, including (the very funny) Doug Glanville, who tweeted “I have to look that up!” followed by “According to a couple of bios I looked at…he bats right! :)” A few others chimed in as well, noting that all of Eck’s career at-bats were taken right-handed.

Sigh.

Anyway, glad my tweet got noticed, sad that something I thought was funny was, in fact, not. Learning experience! I’ll stick to straightforward tweets about the Braves and crosswords and promoting this site.
