found a nice tool to draw diagrams, called

Dia Diagram Editor
http://www.gnome.org/projects/dia/
does support UML.

nice for design diagrams, overviews and so on.

havent checked all of its functions, but its intuitive and works fine.

to get an actual time stamp, also insertable in sql database as date type


import datetime, time

stamp=datetime.datetime.fromtimestamp(time.time()).strftime("%Y-%m-%d %H:%M:%S")


To identify content..


import md5
#file = open("someFile")
#contentstr = file.read()
checksum = md5.new(contentstr).hexdigest()


if you need the absolute path of the script you are running at the moment:

absPath=`echo -n \`pwd\` ;( [ \`dirname \$0\` == '.' ] && echo ) || echo "/\`dirname \$0\`"`

for example useful to build up libary paths in project folders.

to get actual time:

from datetime import datetime
now = datetime.datetime.now()

this will give you a datetime object which is often used by other methods. For string formatting use:

now.strftime(format_string)

* %a – Wochentagsname kurz
* %A – Wochentagsname
* %b – Monatsname kurz
* %B – Monatsname
* %c – Zeit und Datum
* %d – Monatstag 1-31
* %H – Stundenzahl 0-23
* %I – Stundenzahl 1-12
* %j – Kalendertag 1-366
* %m – Monatszahl 1-12
* %M – Minutenzahl 0-59
* %p – AM oder PM
* %S – Sekundenzahl 0-61
* %U – Wochenzahl 0-53 (Sonntag 0)
* %w – Wochentag 0-6
* %W – Wochenzahl 0-53 (Montag 0)
* %x – Datumsangabe
* %X – Zeitangabe
* %y – Jahr 0-99
* %Y – Jahr
* %Z – Zeitzone

This is my first blog.

It shall serve as code repository and help blog for coding problems i often have to face up.

Hope it works and helps me a lot..
