diagrams

666hellrid3r — Tue, 13 Jan 2009 19:00:00 +0000

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.

timestamp

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")

compute checksum

666hellrid3r — Wed, 23 Jul 2008 15:36:19 +0000

To identify content..

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

get absolute path of a script

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.

actual time

666hellrid3r — Sun, 20 Jul 2008 20:11:45 +0000

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
