new version of emacs math symbol input mode (xmsi-mode)

New version of Emacs Unicode Math Symbols Input Mode (xmsi-mode) (for math symbol and unicode input). This version added about 102 full width symbols. e.g. “fw&” becomes “&”. (these chars probably not useful to most, but i use the fullwidth version of ampersand often to avoid encoding complexity in html) happy using.See: HTML Entities, Ampersand, Unicode, SemanticsProblems of Symbol Congestion in Computer Languages (ASCII Jam; Unicode; Fortress).

Perm url with updates: http://xahlee.org/funny/Rebecca_Black_Friday.htmlRebecca Black - Friday (song)Xah Lee, 2011-03-24A 13-years-old girl, Rebecca Black, made a song called “Friday”. It went viral on the net on 2011-03-11, and within a few days, got millions of views. As of today (2011-03-24), it's got 44M views.Here's the video.“Rebecca Black - Friday” amazon I think i first saw the video from twitter. My first impression was: bad song. Monotonic music, brainless lyrics — pubescent teeeens. I closed it without much thought, though i did finish watching it, for my fascination of teens. I didn't know she was 13. I might have taken her to be 16.According to Forbes.com report, she might be making $60k due to the popularity. Here's the exceedingly intricate lyrics. (Yeah, Ah-Ah-Ah-Ah-Ah-Ark) Oo-ooh-ooh, hoo yeah, yeah … Seven a.m., waking up in the morning Gotta be fresh, gotta go downstairs Gotta have my bowl, gotta have cereal Seeing everything, the time is going Ticki…

It was MozillaUIWindowClass, which is also used by Mozilla Thunderbird. But now for Firefox 4 it's MozillaWindowClass.This is a good change.
