my name XAH

perm url with updates http://xahlee.org/PageTwo_dir/Personal_dir/naming_xah.htmlThe name XAHXah Lee, 2000Btw, the name “XAH” is by design. It is not a Chinese transliteration. I choose XAH as my English legal name. I wanted a unique name. Out of myriad letter combinations, XAH came to be more or less because I am fascinated by symmetric alphabets since young. There are still a lot possibilities of names with symmetric letters, but XAH seems to be good and was chosen.It would be fun to write a program to generate all plausible names that are composed of symmetric letters. Anyone risen for the challenge?By the way, alphabet may have vertical mirror symmetry (A, M, U...) or horizontal (B, C, E...) or 2-fold rotational symmetry (N, Z, S), or 4-fold rotational symmetry with mirror (X, I), or diagonal symmetry (idealized L, Q), or a combination of the above (H, I, O).

military combat in Second Life

Perm url with updates: http://xahlee.org/sl/sl_military.htmlSecond Life MilitaryXah Lee, 2009-12-14Some great and not so great videos of Second Life's combat and military.“The Ordo Imperialis: Litany”. Ordo is one of the biggest military in Second Life. This vid is rather professionally done, with much editing, and is not untouched recording of the game. The bluish glow building in the video is the base of another military, the Chthonic Syndicate. “Merczateers MAC-10 '08”. Merczateers is one of the biggest military in Second Life. This one is funny. The red flag in the vid is another military, Chaos Decretum. “Chthonic Syndicate - Recruitment Video”. “Mercz vs Chtonic Syndicate”. This one shows a actual military battle in Second Life.
