Not a lot here for now, visit my static page.

Formatting

Demonstrate text styles: italic, bold and bold italic.

Ampersands are allowed: &, and so are other characters that need to be escaped in HTML: <>.

HTML formatting: Bold

Italic

Underline

Strike out

Colored Red, Green, Blue, ...

typewriter font

Strong

Formatting a whole span, e.g. with small font

Use ^superscripts and _subscripts especially useful for simple formulas

Invisible comments that only appear while editing the page: (not visible on this page now!)

What about Umlauts? "äöüÄÖÜß" should be ae oe ue AE OE UE and sharp s.

Is this '€' an (ISO-8859-15 encoded) Euro sign? See the horizontal line below?

And some mathematics: $\int _{-\infty }^{\infty }e^{-x^{2}}\,dx=(-1/2)!=\Gamma (1/2)={\sqrt {\pi }}$.

Table example.

PEER	IP Address	Name	Location	delay (min/avg/max)[ms]
1	194.88.212.200	eth0-0.yuffie.projectdream.org	Switzerland	20.3/20.9/21.3
2	204.9.53.11	eu.ntp.your.org	Illinois	4.9/4.9/5.1
3	80.239.2.146	mail01.tjgroup.no	Norway	29.3/29.9/31.6

A silly code example (some Scheme I needed at the time I wrote this into another wiki).

(call-with-input-file "code.txt"
  (lambda (port)
    (do ((i 0 (+ i 1))
         (c (read port) (read port)))
        ((>= i *code-length*))
      (display (list i c))
      (newline) )))

Note that the leading spaces automatically produce a display in typewriter font.

HMPQS

The Hypercube Multiple Polynomial Quadratic Sieve (HMPQS) is an algorithm for the factorisation of large (up to about 110 digits, where the Number Field Sieve (NFS) algorithms become more efficient) integers. Uli Meyer has written an implementation in Common Lisp.
