A Pretty Good Average

June 12, 2011: This post completely fraks up the calculation of David Smyth's Base Runs statistic. I've now fixed that, and added the data from 2009 and 2010. You can find all the updated tables here.

I'm a big fan of Sabermetrics, the use of statistical information to understand how baseball teams win games. Part of this is my love for the game, part my natural tilt toward numerical data, and part is that I've always enjoyed reading Bill James's work (full disclosure: he and I overlapped at KU, though we never met). Not to mention the fact that, from my desk, I can see several editions of both The Baseball Encyclopedia and Total Baseball.

But … in the old days, we judged batters by average (> 0.300 is good), home runs (> 30), and runs batted in (> 100). That was it. These stats have some problems: batting average doesn't tell you how many times a guy gets on base by walking, you can only bat in runs when your teammates are already on base, and as for home runs — well, OK, home runs are a pretty fair way to determine part of a players value.

The inadequacy of the traditional trio of AVG/HR/RBI led to the development of new measures for player performance: On-base percentage, slugging average, runs created, etc., etc. The problem is that off the top of my head I don't know what's a good number for any of these statistics. OK, a slugging percentage of 0.900 is better than 0.400, but is a player who slugs 0.500 a power hitter, or just Joe Shlabotnik?

Designing a Random Photo Album

More on my Church Web Page redo:

It's nice to have a picture on the front page, showing the church, or, more importantly, the people who make up the church. It's even nicer to have the picture change occasionally.

The ideal way to do this is to make a Flash slideshow, something easily accomplished with SWFTools, available in fine Linux distributions everywhere. It's fairly simple: Load up all the pictures in order, and export the file, possibly making a political statement everyone in the Universe will ignore. ahem Sorry, some things die hard.

The advantage of Flash is that everything is loaded into your visitors browser once, and then stays there, rotating pictures, for as long as she/he is on the page.

The disadvantage, at least with the method used here, is that the pictures are always in the same order. Which means that the casual visitor, who only stays on your site for maybe 60 seconds at a time, will only get a few pictures, always in the same order.

Not to mention, every time you add or subtract a picture from the lineup, you've got to recompile the animation — not an onerous task, but an annoyance.

PHP can solve part of this problem.

[Why Would You Want To] Run Multiple Copies of Internet Explorer[?]

Comes the time in the life of every web page designer, including those of us who are in no danger of losing our amateur status, when he must face the fact that half of is audience is going to be using Internet Explorer to view his artwork.

And not just the current version of Internet explorer. There's IE8, IE7, IE6, and, dear Lord protect us, even IE5 is sometimes seen in the wild. Of course, each version of IE has its quirks. IE6 does CSS badly, IE7 does it a bit better, and IE8 is better yet, though not perfect. To show you an example of the differences, here's a screen shot of one of our pop-up menus. The first one's IE8, but it's pretty much the same in all reasonable browsers:

Then there's IE7, which looks like this:

Page Under — Construction?

More on Church web page design:

In general, I tend to agree with the notion that under construction web pages are lame. However, a church is a collection of committees, and not every committee runs on the same schedule as your humble webmaster, especially during a Washington summer. So some pages just aren't ready yet. I have the structure of the web site set up, and I don't want visitors to jump to the File Not Found page when they click on a menu item. Something is needed to fill that empty space.

So I picked this icon off the under construction is bad page:

It's Da Vinci's helicopter, of course. An object that probably would work, but just hasn't been built yet. Perfect for a web page that isn't quite ready yet.

Amateur Web Page Design

Let's put this right out front: I'm not a professional web page designer. I'm not even a low-handicap amateur web page designer. I flunked web page design.

However, I have put together at least one web page that gets a lot of attention in its field — more for its content than for its looks. So, I guess, I'm a somewhat competent web page designer.

As a result, over the last dozen years or so I've been in charge of keeping up my church's web page. The thing just grew, sort of like Topsy. It started out as a high school web design project, the designer left for college and I just kept adding things. Sermon pages, Christian Education pages, newsletters, etc.

It got to be a bit of a mess.

Stupid X Tricks

Buried in this Penguin Pete Post and Comments is a trick that I'd never seen before. It could be extremely helpful, albeit tedious to use, if your mouse suddenly scurries off or is otherwise inoperable, and it works in any setup running X:

• Do a 3-figured salute using Ctrl-Alt-Numlock, (in Gnome and KDE, it's Ctrl-Shift-Numlock)
• Press one of the arrow keys on the keypad
• The mouse cursor will move on the screen. A bit of experimenting shows that the "5" key is button 1, and 1-3-7-9 move the cursor diagonally. (OK, I looked here. But the diagram is almost unreadable, and I probably would have hit on it eventually.)
• Unplug mouse, free up USB port. (Well, maybe not.)
• Apparently you can also do this with that Microsoft product, though not in the same way.
• Apple? Don't know.

You stick around now it may show

Forty years ago, on this very day, the Beatles shot the cover picture for Abbey Road.

The crosswalk is still there. A few years ago somebody at the Abbey Road Studio had the bright idea of pointing a web cam at:

Because I Never Remember to Save This

From xkcd

Found in Translation

You can do everything in Emacs, the One True Editor: read email, browse the web, check your calendar, play Conrad's Game of Life, talk to a shrink, oh, yeah, even edit files.

And now you can call up Google, Babelfish, or a couple of other translation services directly from an Emacs buffer. Load up babel.el, highlight a region, do

M-x babel-region

and your translation appears in another buffer.

Thanks to minor emacs wizardry for pointing this out.

Now if it just had a hook for Latin.

Battlestar Galactica: The Summary

After considering the body of work that is the remade Battlestar Galactica, I offer this summary:

Be kind to your sheet-metal friends,
For that toaster is somebody's mother,
We make them do all our hard jobs,
And program them so they can't sob.
Now you may think that they'll kill us all,

WELL THEY WILL!

The Back of the Ticket

From the back of the Washington Nationals Baseball ticket for May 15, 2009. Footnotes added.

By the use of this ticket, the ticket holder agrees that: (a) he or she shall not transmit or aid in transmitting any information about the game or related activities to which it grants admission,^a including, but not limited to,^b any account,^c description, picture,^d video,^e audio,^f reproduction^g or other information concerning the game or related activities^h (the Game Information); (b) the Club issuing the ticket is the exclusive owner of all copyrights and other proprietary rights in the game, related activities,ⁱ and Game Information; and (c) the participating Clubs, Major League Baseball Properties, Inc., Major League Baseball Enterprises, Inc., MLB Advanced Media, L.P. and each of their respective affiliates, licensees and agents shall have the perpetual^j and unrestricted right and license to use his or her name,^k image, likeness^l and/or voice^m in any broadcast, telecast, photograph, video and/or sound recordingⁿ taken in connection with the game for all purposes and in all media^o known and unknown^p throughout the universe.^q Breach of any of the above will automatically terminate this license and may result in further legal action.^r

^aSo if you sneak into the game, you can do any of these things?

^bDon't worry, we'll think of other things later

^cWhich is why I can't actually tell you about the game

^dNo snapping pictures with your cell phone

^eRemember Sonny ripping the film from the camera? Applies here, too.

^fThe cell phone conversation, where you called your wife to tell her the game was going into extra innings? Verboten

^gEven with sock puppets

^hSuch as the young woman bouncing up and down three rows in front of you

ⁱThis includes all bubble gum, sunflower seed shells, and tobacco wads spit out by players during the game

^jOne of the five people you meet in heaven will be an MLB Lawyer. Oh wait, if there's a lawyer there …

^krcjhawk will now forever be associated with the Washington National Baseball Club

^lWell, I don't suppose they'll be using my likeness, but that woman three rows down …

^mI have been told that I have a voice made for blogging.

ⁿWait! We left out Leroy Neiman pantings!!!

^oWhew. For a moment I'd thought we'd left a loophole.

^pJust in case sending pictures via DNA encoding ever becomes popular

^qAt least on Arcturus they don't complain about us calling our championship the World Series

^rA century from now, if we find you put a picture of this game in a scrapbook, we'll exhume your body, drag it to the site of the Spanking-Brand-New Washington Nationals of Boise Park, and cast it out through the front gate. Then we'll sue your heirs.

The World's Best Visual Illusions

Well, I'm not sure they're the best, but here are some really neat visual illusions, including why a curve ball appears to make a sudden break as it reaches the plate, when we know it's really making a smooth curve.

Preserving My Web History

Back at the dawn of the Internet I had a GeoCities Web Page. For its time, it was marvelous. All you had to do to keep up with the terms of service was to make sure each page had a link to the GeoCities home page, and upload files through a somewhat clunky web interface.

I haven't touched the thing since about 1997, but it's still up on the web.

Not for long, unfortunately. Yahoo, which bought the place in 1999, is boarding up the site sometime this fall.

So, for posterity, I've downloaded my contribution to early web culture and uploaded it to my current free web site. That I was able to do this tells you something about why GeoCities is about to go the way of Thylacinus cynocephalus: AwardSpace gives me free web space so long as I register my domain with them, with minimal restrictions, and I can manage it with standard ftp. All I have to do is remember to keep my domain registration active.

Looking back on the thing, the only part that might still be relevant are my book reviews, most of which I did as a paid-for-connect-time science advisor for GEnie. They aren't particularly dated, but I obviously needed an editor to go over them. I've also mis-remembered some of the reviews. For example, I was certain that my review of The Curse of the Bambino started with the line Red Sox fans whine a lot, but that turns out not to be the case. (And, the curse having been obliterated, this is the most dated of the reviews.)

Anyway, it's a new home for old web pages, at least until AwardSpace disappears, hopefully in the far, far future.
