There's an hilarious xkcd post about bad movies in general and the Star Wars holiday special in particular. "How," I wondered, "could anything possibly be that bad?" So I asked YouTube.
At first, I stared in disbelief. Then, I started laughing. Then, from the deep recesses of my soul, some tortured voice started calling out: "What are they doing?" it said. "This isn't right!" it said. "Make it stop, please make it stop!" it cried. So I closed the browser window, hoping that some vestige of my sanity remained.
I had watched for very slightly more than 60 seconds.
In other news, I went to Taco Riendo in south Provo (it's one of those cursed restaurant buildings that can't make up its mind -- the genealogy so far is Wingers->Tandoori Grill->Taco Riendo). It was really good -- I'm hopeful that it might hang on. So far I've only had the tacos ($1.59 each--you get a soft corn tortilla, a pile of meat, and free access to the taco fillings bar). It has very little in common with Taco Bell, which is a good thing. I also got a piece of flan, being that I am a sucker for flan, and it was really good. It dwells somewhere between custard and cheesecake.

Zeno's paradox
One of the more famous Greek puzzles is called "Zeno's paradox," named after the philosopher who conceived it. The problem goes something like this:"Achilles, the great warrior, was to compete in a footrace with a tortoise. Because Achilles is so much faster, the tortoise was given a large head start. Supposing that Achilles started 100 meters behind, and is ten times faster than the tortoise--well, he should run 100 meters, but in that time the tortoise has moved 10. So Achilles runs another 10 meters, but in that time, the tortoise has pulled ahead by 1. So he runs 1 meter, but in that time, the tortoise has stayed ahead by a tenth of a meter. As he runs a tenth, the tortoise holds his lead by a hundredth. Achilles must cover an infinite number of such smaller distances; and since no mortal can complete an infinite number of things, surely it is impossible for him to catch the tortoise!"
It's an interesting paradox. The thing that's so interesting about it, however, is that it also has quite a simple solution. To begin, this paradox tells a lie: "No mortal can complete an infinite number of things." But if the infinite number of things is ever smaller and smaller, then sometimes we mortals can do precisely that. Suppose I try to solve this problem first:
"I wish to sum up all of the distances which Achilles will travel: First the hundred meters, then then 10, then the 1, then the tenth, then the hundredth, and so on, forever. How large a number shall I have when I am done?"
Well, the answer will look very much like this:
111.11111111111111...
except of course that the string of ones shall go on forever. But this number is not infinite. In fact, consider the decimal representation of 111 and 1/9 (one-hundred-eleven and one-ninth). If you do the long division, you will soon realize that it is 111 followed by an endless string of 1's after the decimal point. Thus, the sum of the earlier infinite series is precisely 111 and 1/9 meters, which is the point in the race where Achilles will pass the tortoise.
And there you go: How to answer Zeno's paradox. I hope I said it clearly enough.

Debating Health Care (Poorly)
I've been hearing a lot about the state of health care in the United States. Since I have some strong opinions in this area, I present you with my own rant on the topic.
Before digging in, I wish to start with a little bit of Chinese history. Fifty years ago, Mao Zedong started introducing a series of agricultural reforms to the new agricultural communes in China. These reforms were unscientific and had not been tested; grain production dropped by nearly a quarter over the next three years. To avoid government anger, officials would exaggerate their productivity in their official reports, which in turn led the government to requisition too much grain for state projects. This cycle of deception led to the deaths of tens of millions of people by starvation--comparable to the entire body count of World War 2.
Much of the grain taken by the state was being routed to work crews building massive infrastructure--dams, canals, and so forth. Unfortunately, many of these were so poorly designed and constructed that they turned out worthless. Many trained engineers had been disqualified from the work because Mao Zedong had ideological problems with them.
Mao's successor in the communist party was named Deng Xiaoping. Deng Xiaoping abandoned many of the communist economic theories and moved China toward a comparatively capitalist system. Defending this, he said "I don't care if it's a white cat or a black cat. It's a good cat so long as it catches mice." He had been forced out of power during Mao's lifetime due to his willingness to apply market economics to China's problems. After Mao's death, he returned to prominence, and is the architect of much of modern China's prosperity. Deng Xiaoping advocated seeking truth from facts. And this is what I feel is often missing from health care debates: People make emotional or ideological arguments, with no reference to actual facts about health care.
A handful have claimed there is no need for reform. Sen. Shelby (R-Ala) claimed that Obama would destroy "the best health care system the world has ever known." Of course, he is already on government health care, so I'm not sure how to interpret that. Still, what does he mean that it's the best health care in the world? How do you even measure that? The two most obvious measures that come to mind are:
1. What is our life expectancy?
2. What is our infant mortality rate?
The problem is that the United States does badly on both of these measures. And it's not just a problem of having a large population: Japan, Canada, the United Kingdom, and France are crushing us soundly, and all have 50+ million populations.
While some of the difference is probably the poor American diet and activity levels, how do you explain the infant mortality rate? Infants all weigh pretty nearly the same amount. Besides, the problems with our health care can be measured in a host of other ways (error rate, amount of preventive care, etc.), and we fare poorly on these measures as well. There's an article linked at the end if you want some actual numbers.
There's been a lot of ideological name-calling. Claiming that health care reform is evil because it is "socialist" is an attempt to evoke the ideological red scare of yesteryear. The fact is, most of the health care systems that are destroying us on efficiency, outcomes, and access to care are socialized systems. Is it okay for more of us to die or get sick so that politicians can score points? Or do you believe that America will implement socialized health care more poorly than other countries which have done it? Why do you believe we are less competent than they are?
Some believe that government always performs poorly compared to the private market. What is this argument based on? Do you believe private mercenaries would do better than our army? Do you believe a network of private toll roads would be preferable to the Interstate system? Do you believe that the heavy government price regulation of our water, sewage, and electrical systems has resulted in poor delivery of these services? The truth is that government does certain things better than private industry, and this is a well studied issue in economics. Further, health care run fully by the government has been tried and tested dozens of times in dozens of places, and many of them are healthier than we are. It's not an automatic failure.
I think there's a hidden issue behind this hatred of government programs. American social programs are usually directed at the poor. The middle class gets taxed to pay for these things, but we don't see the benefit. I agree that this is genuinely unfair. We don't resent roads because we all see the benefit from roads. We don't resent national parks because we can all visit them. We don't resent the military because the military defends everybody. I think that a basic level of health care should also be available to everybody, however that is accomplished. I think that there'll be a fair amount of bellyaching tell it gets passed, but as long as the benefits hit everyone, we'll shortly be wondering how we lived without it.
Finally, I refer you to someone who's done a lot more research than I have. This article is much longer than this post, but is backed by a great deal more research. You may not like its conclusions, but if you wish to contradict them, do so with actual facts. Please don't fight back using pure ideology. Because if there's one point I hope I made at the beginning of this post, it's that the cost of clinging to ideology in spite of reality is measured in human lives.

We ran out of candy
It's a little late, but are some random snippets about the Halloween party.
Nearly everyone showed up late. Most of the food did, eventually, get eaten (and the barbecue turned out amazingly well), but it was more a trickle through the evening rather than a big munchfest.
Seriously, the barbecue was great. I still need to figure out a safe way to use a charcoal grill on my balcony. I put a tarp down just in case, and it ended up with small holes burnt in it. Scary. I used a sauce called "Soy Vey" for the marinade (this is what happens when Jewish people marry Chinese people), and it was really good. Just wow. I think you need to grill over hot charcoal to get the full effect, though.
A few people dressed up as rock stars. I wore solid black (I wanted some depressing jewelry, but couldn't find anything I liked). Kim probably wins best costume, though Ismail also made a good shot at it. Curt & Shana showed up nicely costumed, though they didn't go for the rock star thing. Mary gets an honorable mention :).
We played quite a lot of Rock Band. This was the point of the party, and it was entertaining. Thanks to Ismail for bringing the Beatles edition. It was good variety!
Apple crisp with cream on top is delicious. I should purchase some method of whipping cream.
I had a veritable horde of children descend upon my home. This is a refreshing change from the last few years up in Orem, when I didn't see a single child. Nathan and I knew we'd probably get more trick-or-treaters this year, so we purchased four large bags of candy. Ismail also donated a bag of Mexican candies, so there really was a lot. No matter -- the doorbell rang every few minutes for an hour or so, and we were completely out of candy by seven o'clock. It was kind of embarrassing, though no one played any tricks (that I know of...). Next year, we shall buy TEN pounds of candy. Crazy kids and their insane sugar requirements!
Congratulations on the mission call!

124th post!
Wow, 124 posts! And as you know, 124 is a really nice round number, so this is usually when you stop and talk about how much you've posted, right?
The prime factors of 124 are 31, 2, and another 2, you know. And it's the model number of some Russian airplane. And it's ... yeah, there's nothing special about this number. Unless, that is, you are counting in base 31, in which case this number is '4,0' but in that case you are out of your mind, you crazy people. However, I forgot to say anything on my 100th post, and it's getting embarrassing. Not that this helped.
The best thing that happened today was a decently good veggie burrito at Bajio's for dinner. It has caramelized onion and corn and sour cream and stuff in it, and it's one of my favorite things there. Of course it tastes much better chimi-style (deep fried and crispy), but it's a lot less healthy that way. I *do* try to be healthy sometimes.
It's a pity that the reason I was at Bajio's is because I was putting out fires at work and way too stressed to do anything leisurely for dinner. It would've been more fun to be going there because I felt like a veggie burrito. But be the reasons whate'er they will, it was a good burrito.
The fires are mostly out, by the way, but not completely out. One small consolation is that they are no longer my problem.

Feeling Vaguely Important
Last week was not my first time giving job interviews. I've given a few job interviews, occasionally to people that we hired. However, last week was my first time giving a job interview to someone significantly older than me. I'm aware that by the time you reach adulthood, age matters a great deal less in determining positions of authority, but it was still pretty strange.
I still hadn't had a chance to run out and grab cheese by mentoring time, so we ran by a grocery store on the way to my place and had him pick a cheese flavor. He went for sharp cheddar. I couldn't stand sharp cheddar when I was 10, but it tasted good and he enjoyed it, so no complaints.
At a certain sister's suggestion, I'm holding a Halloween party this weekend. If you actually know me then you're invited (I don't know how many random internet denizens I have reading my blog, but you guys are totally getting left out in the cold here). We'll be playing Rock Band and (maybe) Dance Dance Revolution. If you want to dress up, dress like a rock star (this requirement restricts you in no way, given what I've seen of rock stars; think of it more as an inspiration). It's also way past time I had a barbecue, so the food will be grilled deliciousness. If you are vegetarian and wish to attend, warn me and I will try to have something filling that doesn't contain animal products.

Toasted Cheese Sandwiches
It's funny. I'm always tired in the mornings, so why am I never tired enough to fall asleep at night? It's one of the great mysteries of the universe.
I'm hanging out with Camren the protégé after sleep and work (I'd say "tomorrow," but that's not strictly...). I'm planning on making toasted cheese sandwiches. I have good bread, but the only cheeses in the fridge are a delicious old world swiss and parmesan. I may have to go and buy some cheddar. I had the swiss with potatoes and veggies yesterday and it was awesome, but kids tend to have uncomplicated palates.
Work has been really interesting lately, but also pretty stressful. I'm working on some genuinely hard problems. I imagine many of my readers can relate -- the actual work can be very hard, very tiring, and very frustrating, but the immense satisfaction you get when it all comes together makes it all worth it. I suppose a lot of good things in life are like that.
One of my current pet projects* is to build some videos that explain what our software does and how it works. One of the big problems with working for a company that develops 3-d modeling plug-ins that provide a new formulation of curved surfaces (with associated modeling tools) within existing CAD/CAM packages is that I don't really have a comprehensible answer to "what do you do for work?"** Hopefully, a video that explains what I do will be a slightly better answer than "here, look at some pretty pictures of jewelry! Also, electric guitars!" which is how I currently explain it.
OK, time to attempt sleep.
* Yargh, I have multiple pet projects.
** That was a joke. Laugh.
