This script generates TOC for Github Wiki pages, taking their rendered HTML form as input (implied: it's sensitive to prospective page layout changes).
Usage:
$ curl -s https://github.com/<user>/<project>/wiki/<page> | \
./githubwikitoc.rb

Definíció.
- Aritmetikiai függvényen a valós számok egy részhalmazán értelmezett természetes szám értékű függvényt értünk.
- Sorozaton a természetes számokról a természetes számokba képező függvényt értünk (0-t beleértve a természetes számok közé).
- A számjegyösszeg-függvény,
$sz(n)$ a következő aritmetikai függvény:$sz(n) = \sum_{i\in X} a_i$ , ahol$n = \sum_{i\in X} 10^i a_i$ ,$X$ az egész számok egy nemüres, véges halmaza, és minden$i \in X$ -re$1 \le a_i \le 9$ . - Egy
$s(n)$ sorozat stabil, ha van olyan$k$ , hogy$m,n \ge k$ -ra$s(n) = s(m)$ ; ez esetben az$s(n), n \ge k$ értéket a sorozat stabil értéknek hívjuk. - Az iterált számjegyösszeg-függvény,
$sz^*(n)$ a következő aritmetikai függvény:- adott
$n$ -hez képezzük a következő$s_n$ sorozatot:-
$s_n(0) = n$ ,
-
- adott
-
$s_n(k) = sz(s_n(k-1))$ ahol$k \ge 1$ ;

This script spawns you a file server which serves files of various markup formats by rendering them to html. Might come handy if you are writing up something in markdown/rst/etc. and want to check the work you've done.
It needs Ruby and Pandoc (to which we refer for the list of available formatters).
$ vmtree -h | head -1
Utility to display cloud images and servers' inheritance tree.
The nova client program (and the web UI) is a source of comprehensive information on an OpenStack deployment. This information, however, is presented in a strictly typed manner: you get information either on servers, or images, or networks, or whatever entity, but on one of these at a time.
Some information is though inherently heterogenous. One such is the inheritance tree, involving images and servers. Images beget servers by instantiation, and servers beget images by snapshotting. It might be convenient to get an overview of these begetting relations. vmtree is an utility to display the tree that they consitute.
