### Unicode 7.0 Released, Supporting 23 New Scripts

Many of the stylistic duplicates, for example the half-width and full-width latin forms that you mentioned, are only in Unicode because of backwards compatibility with pre-Unicode character sets. If there hadn't been character sets that had different encodings for half- and full-width forms, Unicode never would have had them either. So you can't use them to argue for more glyph variations in Unicode. The same applies to many of the formatted numbers, such as the Unicode characters "VII" (U+2166), "7." (U+248E), "(7)" (U+247A), and "1/7" (U+2150), and units of measure ("cm^2", U+33A0).

(Oh, for Unicode support in Slashdot....)

### Unicode 7.0 Released, Supporting 23 New Scripts

Re:Klingon in more useful (108 comments)

There is already at least one effort to extend Unicode beyond the current maximum of 1.1 million characters: The UCS-X Family of UCS Extensions. It defines UCS-G, which supports over two billion characters, UCS-E with over nine quintillion, and UCS-Infinity with no upper bound. They each support 8-, 16-, and 32-bit variable-byte encodings (e.g. UTF-E-32, UTF-Infinity-8). Itâ(TM)s been a while since I read about them, but I believe they are all compatible with UTF- 8, 16, and 32.

### Google Guitar Doodle Song Gallery

There is, in fact, one sharp, because the doodle is in the key of G.

That's G as in Bach's Minuet in G. I can't play the rest of the song properly due to the lack of accidentals and notes below G.

### Improving Productivity (With Science)

There's a link to the Windows version of Divvy on the Mac Divvy page.

I use WinSplit Revolution, though. It's a free Window app that is similar to Divvy.

What I really wish I had, when I must use Windows, is a Windows version of xmonad. It has excellent support for arranging windows within large screens and on multiple monitors, once you get used to it.

### Diablo 3 Hands-On

I purchased Diablo II. The DRM wouldn't let the game run without the CD-ROM in the drive, even though I did a full install so all the files were on my hard drive. The game was intentionally crippled, making it less convenient to play. (What if I had another CD-ROM in my drive? What if I wanted to listen to an audio CD?) I installed a no-CD crack.

A couple years later I reinstalled it. It wouldn't play; it kept failing because the DRM said the disc was not in the drive. It was. I had to crack my purchased copy to play it.

### How To Enter Equations Quickly In Class?

I second this. If you don't know TeX math commands, there are toolbar buttons, menus, and dialog boxes for everything. But once you do learn the commands (and the TeX commands are listed in the menus and appear as tooltips over the buttons), you can just type them. So instead of pressing the subscript button, you press _ and the display switches to subscript mode. Instead of clicking the sine function, you type \sin. Instead of clicking the fraction button, you can type \frac.

Also, text entry is pretty easy. For example, after creating a fraction two empty blue squares appear--the numerator and the denomerator. Focus is in the numerator, and you can press Tab to switch to the denomerator. Pressing the spacebar exits the fraction, putting the cursor just after it.

### A Mathematician's Lament — an Indictment of US Math Education

Re:The way math is structured is disconnected from (677 comments)

If you read the Wikipedia article on Maya numerals, linked to above, you will see that it is not like Roman numerals. It is, in fact, a base-twenty positional system that happens to have logical symbols for its digits (zero notwithstanding).

### Videogame Places You're Not Supposed To Go

The Guardian Legend NES game had a password system to save your progress. If you entered all Js as your password, you started in a strange location 80% of the way through the game with almost no health. I think the area was reachable in normal gameplay, but you needed a key that you didn't receive when using the password. (Therefore, you were locked in when using the password.) My friends and I spent much time wondering what it all meant.

Recently, zoogelio has reverse-engineered the password system and figured out how to get to off-map areas (he calls it the Lost Frontier, finding all sorts of glitches and weird places.

### How Google's High Speed Book Scanner De-Warps Pages

Re:You laugh, but look at this (209 comments)

I think the strange appearance of the hands is due to the hand moving while being scanned. I remember, in high school, moving my hand inside a scanner while it was being scanned, causing all sorts of fun distortions: wavy fingers, extremely long fingers, etc.

I thought White House 2.0 would have been the post-1814 White House, but that must have just been an increase in the minor version number.

### New Neutrino Detector Being Built In Minnesota

The Duluth News Tribune article (the second link in the summary) states that groundbreaking just happened on Friday. The MPR article mentions that work was supposed to start a while ago, but the funding was cut until the stimulus money reinstated it.

Dang. I got an error the first time I tried submitting this article, so I rushed through the second time I wrote it. It must be in the water up here, though, 'cause they misspelled Alec Habig in the article.

### Alaska's Mt. Redoubt Has Erupted

He would say that the US has not had a major eruption since Mt. St. Helens in the mid 80's.

I don't know how what constitutes a "major eruption", but Pu'u 'O'o in Hawaii has destroyed "over 100 homes [...] in a nine-month period" and "189 structures".

### Good Physics Books For a Math PhD Student?

Spivak's *Mechanics* for Mathemeticians, someday (418 comments)

Correction: it's going to be Mechanics for Mathematicians, so it won't help with the heat equation, etc.
