Q: Why is the drinking age 21 and not 18?

A: The Florida Legislature has the power to set the drinking age, and that's what they've decided is appropriate.

In other words, the classic because-we-said-so argument with which we are all familiar. (For the real answer, read about the National Minimum Drinking Age Act of 1984. The history of alcohol purchase age limits by state is also interesting.)

Anyway, Tuesday was my 21st birthday. After I wrote my birthday blog post, I continued studying until the exam (except for a brief study break at Taco Bell). I was gradually joined with other people in my class, and we all sort of ended up commiserating. That's always fun. The exam itself was pretty challenging, but I don't think it was harder than the last one, which I got a pretty good grade on, all things considered.

By the time I was done with my exam, it was already 9:30. Andy picked me up, and we went to Gainesville Ale House on Archer Road. Andrea met us there. I picked the place because it was one of the only restaurants in town I'd ever been to that was open after 11 PM (the others being the Original Pizza Palace and Chili's). Plus, there would be a wide variety of alcoholic drinks to choose from if I so desired.

I so desired. I needed to unwind after that exam. After much deliberation, I decided to get a whiskey and soda (Jack and Pepsi, to be exact). I almost thought the waitress wasn't going to card me, but she did. To eat, of course, I got a burger. Since this establishment was half-bar, they had a trivia contest going on, with the questions and answers being announced over the speakers. The three of us put our heads together and got most of the questions right, although we didn't actually participate.

Andrea had the audacity to ask the waitress whether I would get a free desert. She said I could get a free slice of ice cream cake and brought one out. The three of us enjoyed it together. Andy covered my part of the check since he owed me money (it's a good thing he remembered because I didn't). Then, Andy and I went back to our apartment, where Andy had decorated the living room with balloons and other birthday decorations as a surprise. We threw the balloons around for a little while. After midnight had passed, I started working on homework.

I report my music listening habits to last.fm because I enjoy seeing the statistics. Here are some more statistics for last.fm users: The Obscurometer tells you how obscure your musical tastes are compared to others'. Apparently, my obscurity level is 30.1%, and my musical tastes are more obscure than 27.9% of all users.

And today it's my 21st birthday. I went to work in the morning, and now I'm taking a quick break from studying for the Operating Systems exam I have tonight. Yes, when I decided to take summer classes, I expected that I would have class on my birthday, but the reality was far worse. After the exam, I'm going out to dinner with a couple of friends. And after that, I have to do Operating Systems homework, which I'll probably have to pull an all-nighter to finish. Yay...

(I know, I know, I have to update my age on the sidebar and the bio and everything. It's not like I forgot, but I'm really, really, really, really, really, really, really busy.)

This link goes out to all my friends who misspell "a lot": The Alot Is Better Than You at Everything.

Here at old Florida, there are three summer semesters. Summer A is six weeks long. Summer B, which follows Summer A, is also six weeks long. Summer C spans both Summer A and Summer B. I took Intro to Public Speaking during Summer A, and during Summer C, I'm taking Operating Systems and Finance. Summer A has ended, so the latter two classes are the ones I have left.

Summer course offerings are more limited than during the Spring or Fall semesters, so for my computer science major, I had no choice but to take Operating Systems with one of the department's more infamous professors. He claims that the average score on his exams is 60%, which includes 20% extra credit. He also gives lots of homework, and he's just assigned the term project.

The flipside, as I've been told by my friends who have survived his classes, is that you learn a lot from him. And I seem to be doing just that. I didn't think I would do very well on the first exam, but I got a 77 (which I first misread as 11, my mind precluding the possibility of such a "high" grade). The next exam is on Tuesday night, which also happens to be my birthday. I hope the exam makes it a good one.

The other class I'm taking right now is for my business administration minor. It's Finance (properly, Business Finance), and it's one of the classes that the business college has done a great job with. They record the lectures and post them online, so there's no need to actually attend class. Instead, I download the lectures and watch them at my leisure. The quizzes are also online (but the exams, alas, are not).

I chose to be a business minor because it would give me valuable skills (and because my major requires me to take a minor, but never mind), and this class hasn't disappointed me. I've learned, among other things, the importance of saving for retirement. Plus, I've been doing very well in the class. The way things are going, I could end up with an A. Yay.

I was actually very worried that I wouldn't do well in either of these classes (Finance is said to be the hardest class in the business minor), but I've been busting my hump for them, and it shows. I just hope I can keep up the good work.

I've always thought of the stock market as something that would do me more harm than good if I tried to mess with it. Several times in school, when I was too young to care about these things, we would have to invest imaginary money in real stocks, and whoever had the most imaginary money at the end would win. I lost an incredible amount of imaginary money in these things. I just didn't get it, and I'm still not sure that I do.

Now that my finance class has taught me a little more about investing, I'd be interested in putting my money in stocks if only I could wade through all the acronyms and jargon and figure out how to get started. Two of my professors now have recommended Burton Malkiel's A Random Walk Down Wall Street in class, so that might be a good place to start. Or maybe I need Investing for College Students Who Know Essentially Nothing About These Things and Just Want Straight Answers.

I don't doubt that a lot of you readers have investments and know your stuff. What do you recommend for me?

For today's cool link of the day, I give you Lemonade and Other Things, a new blog by my friend Andrea. She's already written a lot of posts on various subjects, and I've found them pretty interesting. Let's hope she keeps up the good work.

I have done a bit of public speaking already. When I went to a Catholic school, they would make me do readings in church all the time. I would be given a photocopied passage, usually a letter from Paul to some guys. There were slashes inserted between every few words; that was where I was supposed to pause. And then there was a reminder to count to three or five or something between finishing the reading and saying "The Word of the Lord." My parents say I was great at it, but I was just following the directions. I never knew what I was actually saying. Nobody told me what it meant.

I was also asked to give a speech at my graduation from that school and again at my high-school graduation. I happily obliged in both cases. (Public speaking is nice when you know what you're talking about.) And in college, I've already had to take a technical writing class, and the one I picked involved a fair amount of speaking, so I thought I had already met the communication requirement. But nopers.

So, I took Intro to Public Speaking during the Summer A semester, meaning I had class Monday through Friday for six weeks. We gave speeches every week. For our first assignment, which wasn't for a grade, we had to interview a fellow student and present them to the class. Next, we were going to do impromptu speeches, in which we would select a topic and take a few minutes to prepare a short speech. The teacher wanted us to get a lot of practice, so first we did some impromptu speeches that didn't count. He made us pick topics from the news. Mine went terribly.

For my actual impromptu speech, the one that counted for a grade, we submitted quotations and then we would each have to pick one and offer our reaction to it. I mentioned that one already.

After that, we had to give a speech demonstrating a process. I learned quite a bit from other people's speeches: how to make a cookie cake, how to give a headlock in jujitsu, how to save gas. I talked about how to write a song. I was going to play a sample from a song I had recorded, but the audio wasn't working, so the teacher made me sing it. And you thought speaking to people was scary...

Our next assignment was to give a persuasive speech. We would have to persuade the class that a law should be changed. Most people talked about the hard-hitting, life-or-death, hot-button social issues, but I talked about why copyright terms, which are the longest they've ever been, should be shortened. I thought I did a pretty good job on that one. The teacher thought the class as a whole didn't have a lot of enthusiasm, so for the last assignment, he made us do persuasive speeches again.

This time, he said he had $100, and we were supposed to try to convince the class how he should spend the money. Then we would have a vote, and the winner would have the $100 spent on their idea, and they would get an A in the class.

I skipped the first two days of speeches because I was studying for my other classes, and I wanted to be ready for my speech. I thought a lot about what I would want the $100 to go to; I have a lot of pet issues that no one cares about. But then I remembered organ donation awareness, so I tried to persuade the class that the $100 should go to the organ donation awareness group I volunteer with.

I didn't win—the winning idea was to have a class dance party—but I was glad to get my speech over with. And now the class is done, and I'm home for a week. Yesterday I went to a wedding, and today I'm about to pick up my friend Natasha for the airport. Fun times ahead!

It seems there are always tour groups going around campus—year-round, rain or shine. I've wondered how the weather might affect people's perceptions of my fair university, and I assumed that bad weather would show the school in an unflattering light. Apparently, research shows that the opposite is true.

On Monday morning, I attended the closing ceremony of the conference. Well, there wasn't much ceremony; the term used in Esperanto means "solemn closing." It wasn't especially solemn either. It was mainly a series of closing remarks, capped off with a singing of "La Espero."

The organizers of the convention presented some statistics, most notably that the attendance was over 100. The president of Esperanto-USA gave some details about the next national convention, which will be held at the University of California, Berkeley, in early June 2011, and the one after that, which will be held in north Texas in 2012.

I was the only college-age kid to attend the closing ceremony. Once that was over, I rejoined the others in the lobby. Andy, Darcy, and I got to talking about exciting it was to be with so many other young Esperantists and how to keep the energy going. For a while, Esperanto-USA had had an active youth branch called USEJ. We decided bring USEJ back to life by starting up an IRC channel where we could constantly chat with each other and by having regular voice chats online. We also decided to look into the possibility of having a national youth congress in South Florida in the winter.

I've come back energized, and I've come back with a goal. I want to take new Esperantists with me to Berkeley next year. That means Andy and I will have to work hard to attract new members to our club and help them learn Esperanto, but it's a worthwhile challenge.

I didn't actually go to DC at all during the trip, even on the drive to the train station. Yes, instead of flying back to Florida, we took the Auto Train with Andy's dad and Andy's dad's car, which Andy is now using. It was actually pretty comfortable, and I even expected to sleep at one point. I don't think I actually did; I should have known better. But the complementary dinner and breakfast were pretty good, and it was fun to see "America at see level" (Amtrak's former or maybe current tagline).

We arrived in Sanford, Florida, on Tuesday morning, and we drove to Gainesville. As soon as we made it to UF, I raced into my public speaking class, which was already in progress. I was going to have to deliver an impromptu speech. We had each submitted a quotation, and then when it was our turn to give a speech, we had to pick one of them at random and and deliver a speech about our reaction to it.

For some reason, there weren't as many quotes as there were people, and I was the last to go, so I was left with none. The teacher asked people to submit some more, so I had fresh pickin's. I chose:

"We are not here merely to make a living, we are here to enrich the world."
—Woodrow Wilson

Within three minutes, I explained a little bit about what Esperanto is all about and about the experience I had had with other Esperantists over the long weekend. I tied it all together by explaining the shared hope that Esperanto can help enrich the world. I got a strong round of applause, and people had more questions for me after the speech. I got a 98% on the assignment.

The class had four discussion sections, which made it only natural that each discussion section should correspond to a group. The groups were about evenly distributed, each one having 16 or 17 people. In my group, we spent several weeks hashing out ideas for what kind of program to make.

I would talk about the ongoing project to my friend Mark, who had taken the class previously. When he first heard about it, he was shocked. "Seventeen people? That's going to be way too many. You need two or three people." Or, you know, something like that. I'm not a journalist, jeez.

I wasn't really sure what he meant. I figured that with a lot of work, two or three people could complete a project on the scale of what we were doing, but with more people on the team, it would be easier for everyone.

Our group eventually decided on an instant messaging application for Android phones. The app would be designed specifically for our fellow UF students; each user would see a map of the campus with their buddies' current locations marked. Users would also be able to create and invite their friends to events, which would also be shown on the map. The name of the program: ChompChat. The alligator-themed wordplay is inescapable around here.

We basically split ourselves into two teams: the client team, which would make the actual ChompChat application, and the server team, which would be responsible for handling interactions between users. After a while, the server team got something that worked, and the client team got something that worked. The hard part was getting them to work together.

Some of our other assignments for the class involved reading Fred Brooks' The Mythical Man-Month, a classic text of software engineering. The titular essay explains that people and time aren't interchangeable. As more people join a project, proportionally less work gets done because the new members have to learn the ropes and each member has to communicate with more people to figure out what's going on. It's summed up as Brooks' law:

Adding manpower to a late software project makes it later.

In the meantime, I had a hard time finding a place for myself in the project. We were using Google Wave to communicate (we had several big Google fans in the group), and not everyone was in on every wave. We had our own Trac installation set up for us, but no one ever filed any tickets.

I got most of my information from our weekly class meetings, and even then, I couldn't help but bounce around from subteam to subteam, looking for something to do as the strong-willed and more technically able actually did most of the work. It got to the point where I decided to hold off from the development lest Brooks' law come into play. Other members of the group agreed that this was a good idea.

When it came time for the groups to present their software projects, we had just gotten the client and the server to communicate with each other. Chatting and creating events worked, but geolocation and the other features we had originally dreamed up for ChompChat were absent. I felt as though the ghost of Fred Brooks were there in the room, laughing to himself. Actually, I didn't because he's still alive. But whatever.

Fred Brooks was right. Mark was right. And everyone else came around. Toward the end of the semester, the professor took a poll of the class, and almost everybody agreed that the groups should have been smaller. Too bad it took so much manpower to figure that out.

This 1995 Newsweek article reads like satire in 2010: "The Internet? Bah!" A Newsweek blogger provides a modern commentary and manages to get a word from the author.

The event was held on Wednesday evening, the last day of classes, in the smaller ballroom in the student union. There were a lot of empty seats, probably because people were at home studying for their upcoming exams. I guessed that most of the audience members were there to see their guy or gal take part in the discussion; not many people looked like they were genuinely disinterested. I have to admit I was in the former camp. I sat with a group of Freethought members.

(Derail: People always seem to say "disinterested" when they mean "uninterested." I've also seen an excellent clip from The Rachel Maddow Show [which I otherwise don't watch, by the way] in which Ms. Maddow says "uninterested" instead of "disinterested." If you're uninterested, you don't have any interest—you're bored or you don't care—and if you're disinterested, you don't have any interests—anything that could be considered a possible source of bias or prejudice. Paul Brians has an entry on this error in his Common Errors in English Usage web site, which is worth checking out. In the associated book, there's a cartoon in which a man says to a woman something like, "Let me make myself clear: I'm not disinterested, I'm uninterested.")

Um, right. So, the forum was emceed jointly by what appeared to be a Christian and a Muslim. Answering their questions, as well as some from the audience, were the panelists:

• Representing Christianity was a guy from Campus Crusade for Christ. He seemed ill at ease and spoke with thinly disguised contempt at the other belief systems that were represented. He must have said that Jesus "stepped into the pages of history" at least six or seven times. I was surprised they couldn't get a better speaker, considering how many Christians there are.
• Representing Islam was a dapper local businessman. He had a good sense of humor and explained how Islam gives people advice on how to live their everyday lives. He used the word "brother" in referring to some of the other panelists and joked with brother Blake that only a freethinker was brave enough to sit between a Muslim and a Jew.
• Blake was the only student on the panel. His answers were short and to the point (giving him less of a chance to dig himself into a hole, he said later), and he was careful to represent freethought in general without mentioning the A-word. I liked his answer to the question, "Who is the most important figure in your religion (or lack thereof)?" He said, "Yourself," because freethought is about thinking freely (hmm...) and not taking for granted the things that other people tell you.
• Representing Judaism was a local rabbi, who explained how Judaism also gave advice for everyday life. A kid from the audience, badly feigning ignorance, asked him some innocent-sounding questions to try to get him to link Judaism with Zionism. The rabbi didn't fall for it. You could have cut the tension in that room with a knife right then.
• Speaking for all denominations of Hinduism was a distinguished Indian woman of a certain age. She explained how Hindu beliefs and practices vary greatly and called out some of the moderators' questions as being specifically geared toward the Abrahamic religions. She had to dip out about halfway through, so she made a quip about avatars as another distinguished Indian woman of a certain age took her place.
• Speaking specifically for Hare-Krishna-ism while wearing Krishna robes and Krishna face paint was a young representative from the local Krishna House. She gushed with enthusiasm while getting all buddy-buddy with the other Hindu and quoting the Bhagavad Gita in Sanskrit. Though she would get extra credit in the enthusiasm department, she used a lot of terms that were vague (like everyone's favorite, "energy") or not very clear to us laypeople.
• Finally, representing the Bahá'í Faith, whose name I had to copy and paste from the Wikipedia article, was a professor or something (what, you want me to actually read the program I took home?). The Bahá'í Faith (Ctrl-V) is essentially a greatest-hits compilation of the world's major religions, but Ms. Bahá'í Faith didn't do a good job of explaining what it was actually about. She talked a lot without saying very much.

It was a great way for Blake to go out as Gator Freethought's president. He was definitely one of the better speakers on the panel, and even though freethought was the odd belief system out (as evidenced by the tacking-on of "or lack thereof" to seemingly every question), he did a good job of representing our club.

And this is what I do when I should be studying for exams. I'll be glad to have them over with. By the time I write my next post, I'll be home free... for a little while.

Get Carded's annual organ donation awareness concert was on Thursday night, and unlike in previous years, I had an exam at the same time and couldn't help out for most of it. All I had time to do was set up and clean up. Go figure. But I was around to witness us reaching our goal of signing up 50 organ donors. At least, I think we made it. If not, we were very close.

My exam was the crucial second exam in my accounting class. (I'm taking it for my business minor.) To give you an idea of what my accounting class is like: during the first week of class, the TA asked us, "How many of you have heard this class is hard?" Most people raised their hand; I didn't.

Back to Thursday. I was setting up for Lifeapalooza around dusk, when the insects come out to play. Some of them decided to bite my face, and then they decided to bite my face some more. So I took a two-hour exam with an itchy face. After the exam, I needed to show my student ID to one of the proctors, so I shoved my hand into my pocket, opening a cut on my finger and causing it to bleed profusely. Despite those bad omens, I did better than I thought I would on the exam, and a B remains within sight. My weekend has also been pretty mixed, but I'll get to that in a future post.

Right now, I'd like to draw your attention to the fact that I just upgraded WordPress, including my database and several of my plugins. If you notice that any aspect of the blog is broken, please contact me right away.

I've been using WordPress for over five years now, but I've always hated upgrading, so I rarely do it. The official instructions tell you which files to delete and which ones not to delete, but I always feel like I'm going to accidentally delete something important. It wouldn't be a big deal because I always back my stuff up before upgrading, but still, I just don't like it. It's awkward and painful. I liken it to pulling out your own teeth. Not that I've done that, of course.

But if upgrading WordPress the regular way is like pulling out your teeth, then upgrading with Subversion is like having a sexy dentist cart out the laughing gas and take care of everything for you. Essentially, Subversion allows you to download all the updated files with a single command. Pretty sweet. Hopefully now I won't be as lazy about upgrading.

For a long time, I had some measures in place that eliminated automated comment spam but let manually posted spam right through. The manual spam was never a very big problem until recently, so I have some new anti-spam measures that you should also be aware of. For years, I've been too lazy or paranoid to install Akismet, the premier anti-spam plugin for WordPress. Well, I've finally installed it, but I'm not using it the way it's normally used.

Normally, Akismet checks an incoming comment against its database and puts it in the blog's spam queue if it thinks the comment is spam. That's all fine and good, but I get dozens if not hundreds of spam comments every day, and I'm not going to sift through them to find false positives. Fortunately, I've discovered a helper plugin called Conditional CAPTCHA. Now, if Akismet thinks a comment is spam, the submitter will be asked to fill in a simple CAPTCHA. If it's filled in correctly, the comment proceeds to the spam queue, where I can approve or reject it. If not, it is summarily deleted.

With these two plugins working together, automated comment spam is still zapped instantly because Akismet generally recognizes it as such and because robots can't (or don't) solve the CAPTCHA. The spam queue will hold what we might call false negatives (comment spam posted by beings intelligent enough to solve a CAPTCHA) and false positives (the hopefully very few legitimate comments that Akismet thinks is spam). Of course, true negatives (i.e., normal comments) will be merrily allowed through as always. Nothing is different about that.

What's the advantage of all this, you ask? Now, the blog has a defense against both automated and manual comment spam (as long as Akismet can recognize it, which it almost always does). Also, when I mark comments as spam or not spam, the Akismet system learns from its mistakes. Pretty cool. I can teach it that anyone who violates my plainly stated no-advertising policy is a spammer, so don't even think about linking to your irrelevant web site where you sell stuff, or you could be blackballed from other blogs too.

By the way, my roommate Andy suggested the title of this post. Thanks, And-Man.

Oh yeah, and I get to pick my classes on Monday. Apparently my peers all get to pick their classes today or thereabouts, but since I don't have as many credit hours as most of them, I can't register for classes as early. It's not fair, I know... or is it? It probably is. I can't wait to catch up on my credits over the summer so I can register for next spring's classes relatively early. Well, we'll cross that bridge when we get there.

Some of the blogs I read have open threads periodically (or all the damn time). I find them kind of annoying, probably because I don't feel like I'd fit in in a discussion with the rest of the commenters. The World of Stuff, I think, is different. I think you'd all get along with each other, and I don't often abdicate my responsibilities as a blogger by declaring open threads. The circumstances are extenuating this time. That accounting exam won't take itself.

Oh, and The World of Stuff's birthday is on April 6. Happy almost birthday, The World of Stuff!
