It is intentional that these pages use the simplest web technology possible, so as to maximize compatibility with various browsers, and to minimize internet bandwidth consumption. The author does not attempt to stay au courant with the HTML standards du jour; in part because HTML, although it is an excellent tool, has led a confused existence, with some markups indicating how text should look, and other markups indicating how the text should be interpreted.
I am a firm adherent of Sturgeon's Law, which says that ninety percent of everything is garbage. I have no doubt that Sturgeon's Law applies to this very website. Had I any way to discern which of the above pages were indeed vapid trash, I would be pleased to promptly delete them; I welcome nominations.
A persistent recursivist might inquire:
Atlanta driving rules:
Feathers, and most other things, are weighed by the avoirdupois ounce, which is about 28.35 grams. However, gold and other precious metals are weighed by the troy ounce, which is about 31.10 grams. So the ounce of feathers weighs less than the ounce of gold.
Meanwhile, an avoirdupois pound is sixteen avoirdupois ounces, making the pound of feathers weigh about 453.59 grams. But a troy pound is only twelve troy ounces, which works out to about 373.24 grams. So the pound of feathers weighs more than the pound of gold.
With all the attention given to the Ides of March, often overlooked is that every month has an Ides, observed on the following days:
|Jan 13||Apr 13||Jul 15||Oct 15|
|Feb 13||May 15||Aug 13||Nov 13|
|Mar 15||Jun 13||Sep 13||Dec 13|
The English word Ides comes from the fourth-declension Latin noun Idus, so a suitable English adjective would be Idual, on the model of Latin spiritus whence English spiritual.
• Long live the obelus ÷ as a symbol for division! The explicit multiplication symbol ×, although sadly neglected, is also deserving of use.
• We must teach our children Boolean algebra, because it is too simple for adults to learn.
• Beans, eaten directly from the can: real food for real men.
• I calls 'em as I sees 'em. — proverb often attributed to baseball umpires.
• LINGVA LATINA OPTIMISSIMA: Latin is the bestest.
• I shall go to Korea. — Dwight David Eisenhower
• Unshackle yourself from the mathematical ball-and-chain dating back to horse-and-buggy times: seek those algebras wherein multiplication is not burdened by commutativity.
• Perfection is easy to attain if you set your standards low enough.
• I have suspended my support of Major League Baseball until the 1994 World Series takes place.
• In Neapolitan ice cream, the vanilla should be situated between the chocolate and strawberry; in other words the chocolate and strawberry should never adjoin. By the same token, in a Neapolitan citrus sherbet, the lemon should be located between the lime and orange. (The same principle applies to a three-layer cake.)
• What this world needs is a pinto bean that does not lose its spots when cooked.
• Bezier curves are remarkable for their simplicity, elegance, usefulness, computational efficiency, and generalizability.
• Don't trust any musical composer who doesn't know how and when to use double sharps and double flats.
• The best comic ever: They'll Do It Every Time.
• If you accuse me of being a curmudgeonly old crank, you may be right. (Either that, or maybe I'm a cranky old curmudgeon instead.)

 The equally valid but rarely seem system 1-2-4-10-20-40-100-200-400 also has the feature that each denomination has exactly one nonzero digit, and that the sequence of ratios is 2-2-2.5 repeating. The difference between 1-2-4... and 1-2-5... is where the starting point of the ratios is placed.
 By the principle of symmetry, one can argue that prefix syntax ought to be held in the same high regard.
In the never-ending battle among C++ programmers, I stand firmly on the east-const side, rejecting the inconsistency demanded by the west-const adherents. For instance,
|const int i;||int const i;|
|constexpr int i;||int constexpr i;|

That when you were walking forwards
You'd end up further onward,
But things ain't quite that simple"
