The Goblet Of Fire
So anyway, Goblet of Fire. In preparation for the Half-Blood Prince, I've gone back and re-read the whole Potter series, which is not getting any worse with age, I'm happy to say. I'm partway through Order of the Phoenix now, and I have to say it doesn't seem even a little bit familiar, so I wonder if I've even read it. The same thing happened when the fourth one came out, and I only realized I hadn't read the third one when I went back to reread all three of them. I suppose by the time the seventh, and theoretically, final book comes out I'll have read the first one six times.
So anyway, Goblet of Fire. This isn't a real review, just a thought that I had as I was reading it about the villainous newspaper reporter, Rita Skeeter, which has to be representative of J.K. Rowlings real experiences with reporters, and like any good author she's put her own experiences into the book. Still, I think Harry's anger at the reporter putting her own spin on the stories is a little overdone - it happens constantly and for the most part, any publicity is good publicity. The exceptions, of course, are the publicity that I'm sure she's gotten tons of - Harry Potter is anti-Christian. (Note the nofollow tag I've added to that last link. I am a Christian, although a bad one, and I'm obviously a big Potter fan.) I'm sure each time a story or video like this comes out, there's a decent chance of a mailbomb or some other circumstance that will actually cause harm - not like the howlers Hermione received, but something actually harmful. But for the most part, you just have to have a thick skin about any publicity at all - and of course, any real issues you have with the reporting can be discussed on your blog!

Since I'm changing jobs, I'm taking last week and next off. We went to Chicago for four days last week; very disappointed in Amtrak. We thought it would be fun to take a train from Indianapolis to Chicago, so we went to the Amtrak website and bought tickets online. When we got to the station we presented our tickets and the lady said, "oh, that's the bus. You board over there." But really taking the bus wasn't bad; it wasn't terribly crowded on the way up so we got to walk around and stuff. Not nearly as nice as a train car would have been though. We stayed at the Essex Inn, which has some pretty cheap rooms. I can't believe hotels in this day and age don't all have wireless Internet though, so I lugged my laptop there and back for not much reason. So what did we do?
- Field Museum - pretty good, but their regular exhibits are starting to fall apart - they must be putting all their money into special exhibits.
- Museum of Science and Industry - turning into a trip highlight and the new submarine exhibit is really nice. Cathy the Nurse Practitioner really enjoyed the new "Bodies" exhibit, which consists of actual cadavers on display with some kind of plastic gelled into them to make them pretty. Pretty grotesque, I thought. One of the displays had on a white cowboy hat and a notation - "Wearing a hat to show the very slight difference between life and death". I think I would have rewritten it as, "Wearing a hat because, well, we could."
- Shedd Aquarium - Cathy would probably call it a highlight but it's never a total thrill for me. Some of the big fish and the huge anaconda were pretty cool. The dolphins did some nice jumps in their show.
- Children's museum - it's on the Navy Pier, which we discovered you can't walk to from the south side of the Chicago river. We had to walk nearly a mile out of our way to find it. The exhibits are fairly nice, but we wanted the little one to have lots of large-muscle activities in order to tire him out for some grownup museums. The exhibits were more of the sit-down-and-play-quietly type.
- Architectural walking tour - very well done and we will take many more. At one point the guide commented on the evil minorities who sued the city over Millenium Park, and the wonderful industrial leaders who stepped up with replacement money. I refrained from asking if she was an actual schill.
- Adler Planetarium - not bad. I always think it's not a real planetarium unless they have a live guide and a little globe that makes glowing dots on the ceiling, which apparently shows my age. We went to the "Stars of the Pharoahs" Omnimax show, which was pretty good I guess, although I never go to Omnimax shows.
So our feet were hurting by the end of it. We came back on the bus, and this time it was absolutely full and not much fun, but we got the requisite T-shirts and some other souveneirs. Chicago is great fun. I can't wait for the little one to be old enough to do some nightlife.

Book review: Hat Full Of Sky, Terry Pratchett
Boy, that summary makes it sound kind of iffy, doesn't it? It really isn't. The Nac Mac Feegle are back and as feisty as ever, although I think their dialect is significantly easier to understand than in the earlier books. I'm guessing you can't make major characters out of folks no one can understand. Tiffany's interactions with the other apprentices are nicely done, and Granny Weatherwax is fascinating as the other characters now talk about her the way she once spoke of Black Aliss Demurrage. Tiffany's progress as a witch is brought forth nicely, and Rob Anybody really comes across as a personality rather than a caricature like most of the Mac Feegle.
The ending is a bit nicey-nice, which I suppose is appropriate for a book theoretically targeted at younger readers. To me it came across a bit like when one of the great villains of all time, Darth Vader, decided he was really a nice guy after all and was redeemed in a single swoop. C'mon now, bad folks are a lot more fun when they're bad, now aren't they? The Mac Feegle queen was a bit wishy-washy too, and I didn't really buy into her mood swings. Finally, the climax of the book takes place at something called the Witch Trials, which appears to be sort of a renaissance festival for witches. Odd, but again maybe appropriate for the younger reader.
And for all of that, it's classic Pratchett and you can't complain. Most comedy writers, take Piers Anthony or Douglas Adams, get steadily sillier as they reach the later books in a series and have to try to wring one more gag out of the same scenario. But the great ones, like Pratchett and Wodehouse, just keep on kicking out one or two new terrific stories every year. This is one of those. Read it.

Living in the blurbs
when such effusive hyperbole declares everything "brilliant", "superb" and "amazing" it all ceases to mean anything
which is more or less the problem with marketing - that is, the lack of credibility of the source. Are you going to read a book because it says "A real tour de force!" on the back, or are you going to read it because your buddy says it's pretty good? I would be a lot more likely to read a book if it was making the rounds in the blogosphere than for any other reason. So I guess book publishers are another on the list of people who need to learn to make blogs work for them. I know there are a few publisher-bloggers - wonder how effectively they use them to push books?

So you wanna be a programmer?
Joel's alternate suggestion is a straw man, of course. No, obviously learning HTML or copy-and-pasting Javascripts is not quite the ideal learning experience. But I see absolutely nothing holy about C as being just exactly the right level to learn at, and I firmly disagree that learning the technical details about why strings are hard to manage is important for a beginner. That may be the single reason that more people aren't interested in programming, which is a shame considering the myriad of good string implementations that are out there.
But if you must get fairly close to the machine, why not start with a managed language? Being able to move from Java or C# to byte code is going to get you a long way to understanding how your source code is translated to something the machine understands, without having to really bury yourself under a load of machine code manuals.
I would replace this recommendation with Stroustrup's The C++ Programming Language, 3rd edition, which replaces all the stuff about byte copying with good object-oriented design. Going all the way back to C is, to my mind, no more necessary to a programmer starting out today than a recipe for bread has to start with "Grind down enough wheat to produce three cups of flour..."

Book review: A Great Deliverance, Elizabeth George
Luckily, my stomach is a little stronger than that. But I don't think I'll put this one on my wife's reading list.

"It seems more complicated now"
for (i = 0; i<things.count; ++i)
{
Initialize( thing[i] );
}
for (i = 0; i<things.count; ++i)
{
Continue( thing[i] );
}
for (i = 0; i<things.count; ++i)
{
Finish( thing[i] );
}
There is clearly duplicate code here. Three times we run a loop over things. You can't just refactor all three calls into one loop, since the processing of the latter loops might depend on the first loop being finished.
So how do we remove the duplication? Let's create an abstract object, AThingProcessor, and use it to do all of the looping:
class AThingProcessor
{
void Run()
{
for (i = 0; i<things.count; ++i)
{
ProcessThing( thing[i] );
}
}
abstract void ProcessThing( thing t );
}
Now we can replace each loop with an instance of a class, for example:
class Initializor : AThingProcessor
{
virtual void ProcessThing( thing t )
{
Initialize(t);
}
}
And now the original code can be replaced with:
new Initializor().Run();
new Continuor().Run();
new Finisher().Run();
So what is the result? Our original code is now much more object-oriented and flexible. But without knowing the definitions of Initializor, Continuor, and Finisher, you don't know exactly what is happening here. The result is, some programmers will look at this code and say "It seems more complicated now". But it really isn't. It's just more object-oriented.

Weekend family reunion
With all the driving, we didn't really have much time to visit. But we wandered around campus, and discovered that the reason there were no hotels was the big high school volleyball tournament that was going on. My brother is in theory deciding what college he's going to - in reality he'll be going to Indiana - but he gave PSU a thumbs-up as a solid backup choice. He was noncommital, though, as to the part played by all the volleyball players running around in that decision...
Getting Things Done
This is a huge oversimplification of course, and the book recommends a few other tricks. I am deficient in that I don't carry a personal organizer of any kind, for example. But I'm slowly working towards full organization!

ISO 9000 is good
There are two ways of looking at software development. Some people like to look at developers as artisans. They spend a lot of time on a single application, but when it's finished, it's like a really high-quality chair - it's really pretty to look at and works really well. Other people look at developers as assembly-line workers. They kick out a piece of software according to spec, and pass it on down the line to the next worker to glue in. This software is like a chair you can get at Wal-Mart - cheap and quick and does the job.
The truth, as is so often the case, lies in between, but there are a couple of undeniable facts: Not every software developer is an artisan that can make a really great chair. And even if they were, once the original developer moves on to something else, who knows what uses his chair will be put to? So whether or not software is craftmanship or assembly work, procedures are probably going to be necessary for making changes. And in the software world, if you're not making changes, you're dead.
The true raison d'etre for ISO 9000 is that processes can be improved. But you can't improve your process until you know what it is. So observe. Find out what your developers are doing, how they spend their time. (Ask them how it could be better, too. You won't always get a useful answer, but software developers are usually pretty darned opinionated and will have something to say.)
Now you know what your process is, you can document it, and you're most of the way there to your certification. And you'll be even further along once you document how you're going to accept suggestions for improving the process.
Once all that is done, you can change the process. You might see a lot of improvements in front of your nose, right after you write everything down. If your developers tell you they have to get 17 signatures in triplicate before they can issue a fix, you've got room for improvement.
But it all comes down to knowing the procedures. The easiest way to know them is to write them down. And once you have them written down, you're most of the way to your ISO 9000 certification.

Coding principles
* Don't go too long without soliciting input. You need to get input from users, to make sure that the application is doing the right things. You need to get input from programmers, to make sure your design and architecture doesn't overlook flaws. These are the values of Communication and Feedback.
* Make changes when changes need to be made. Don't fall into the trap of avoiding making changes because "it might break something somewhere." Ideally, of course, you have enough unit tests running to verify that things don't break when you change code, or at least that if they do, you know it quickly. But once the code is so complicated you are afraid to make changes, you can't respond to customer input quickly enough to keep up with your competition. This is the value of Courage.
It's interesting that these principles feed off each other. If your code has Simplicity, you are more likely to have Courage to change, which allows you to respond to Feedback more quickly.

Indy NDA and VS 2005 Beta
The main thing that occurred to me during the presentation was how similar the refactoring support looked to Resharper, and how similar the testing stuff was to NUnit. I hope one or both of these companies is getting a cut. (I asked the presenter to compare VS and NUnit but he wasn't familiar enough with it to say.) The refactoring support for VB was pretty jazzy, though. They're also bringing back Edit and Continue, which everyone was grumpy about being left out of earlier versions. It's just one more tool to help people write bad code, IMO. Much better to write well-tested classes instead of changing a couple of lines on the fly for each run.
Another presenter showed off Master Page support for ASP.Net 2.0, which did look pretty nice. I'm still behind in the Web world, but luckily I wasn't one of the six people tonight who went home with no door prize - I picked up a new book on XHTML and CSS. Worlds enough and time!
