Organizing photos into folders by date taken

Aaah, the command line. After downloading from the camera I wanted to move photos into separate directories based on their date

#!/bin/bash

#This is a somewhat inefficent (calls exiftool many times) script that will put pictures
#into a date based directory structure. The script will use exiftool to read the date the
#picture was taken and then move the picture into an apropriate directory

#Requires bash, exiftool
#Works on Darwin and most probbaly any *nix distribution


shopt -s nullglob #if no file is found the pattern *.jpg will expand to itself, but this prevents that

for file in *.[jJ][pP][gG]
do
date=`exiftool -d "%Y-%m-%d" -s -s -s -DateTimeOriginal "$file"`
year=${date%%-*}
mkdir -p $year/$date
mv $file $year/$date/
done

UPDATE:

Hah! This whole script can be replaced by the following exiftool command

exiftool -d %Y/%Y-%m-%d "-directory<datetimeoriginal" *.JPG

Man, exiftool is a powerful program!

UPDATE: Jan 2010
exiftool works with RAW files too

#!/bin/bash
exiftool -d %Y/%Y-%m-%d "-directory<datetimeoriginal" *.JPG
exiftool -d %Y/%Y-%m-%d "-directory<datetimeoriginal" *.AVI
exiftool -d %Y/%Y-%m-%d "-directory<datetimeoriginal" *.NEF

Flowing text in inkscape (Poster making)

You can flow text into arbitrary shapes in inkscape. (From a hint here).

You simply create a text box, type your text into it, create a frame with some drawing tool, select both the text box and the frame (click and shift) and then go to text->flow into frame.

UPDATE:

The omnipresent anonymous asked:
Trying to enter sentence so that text forms the number three...any ideas?
The solution:
Type '3' using the text toolConvert to path using object->pathSize as necessaryRemove fillUngroupType in actual text in new text boxSelect the text and the '3' pathFlow the text

Pandas panel = collection of tables/data frames aligned by index and column

Pandas panel provides a nice way to collect related data frames together while maintaining correspondence between the index and column values:


import pandas as pd, pylab #Full dimensions of a slice of our panel index = ['1','2','3','4'] #major_index columns = ['a','b','c'] #minor_index df = pd.DataFrame(pylab.randn(4,3),columns=columns,index=index) #A full slice of the panel df2 = pd.DataFrame(pylab.randn(3,2),columns=['a','c'],index=['1','3','4']) #A partial slice df3 = pd.DataFrame(pylab.randn(2,2),columns=['a','b'],index=['2','4']) #Another partial slice df4 = pd.DataFrame(pylab.randn(2,2),columns=['d','e'],index=['5','6']) #Partial slice with a new column and index pn = pd.Panel({'A': df}) pn['B'] = df2 pn['C'] = df3 pn['D'] = df4 for key in pn.items: print pn[key] -> output …

Drawing circles using matplotlib

Use the pylab.Circle command

import pylab #Imports matplotlib and a host of other useful modules cir1 = pylab.Circle((0,0), radius=0.75, fc='y') #Creates a patch that looks like a circle (fc= face color) cir2 = pylab.Circle((.5,.5), radius=0.25, alpha =.2, fc='b') #Repeat (alpha=.2 means make it very translucent) ax = pylab.axes(aspect=1) #Creates empty axes (aspect=1 means scale things so that circles look like circles) ax.add_patch(cir1) #Grab the current axes, add the patch to it ax.add_patch(cir2) #Repeat pylab.show()
