alexwlchan / image-width-rescaler
Created May 1, 2013
This is a quick AppleScript written to shrink wide images to at most 1200px. To use it, open it in Script Editor, then save it as an Application, and drag files on to its icon in Finder. Target width is set in line 17. We can similarly use it to shrink tall images if we want to.

Last active Jan 2, 2016 — forked from cliss/organize-photos.py
My fork of @cliss’s photo management script. Tweaked to: * Get date from `os.path.getmtime(f)` (lifted from @jdmonaco’s fork) * Sort any format with a three-character extension (currently .JPG, .TIF, .PNG and .MOV). Edit the list in line 40 for more formats. It also normalises extensions to lowercase. * Tweaked some bits of the code * Moves file…

Unpack sets and ranges expressed in a string, using cURL syntax for multiple URLs
View curlparser.py
"""The cURL command line tool allows you to specify multiple URLs in a
single string. For example:

ftp://ftp.letters.com/file[a-z].txt
This module can take a string in this format, and return the list of strings
that it specifies. The exact syntax can be seen in the examples on the cURL man

Non-destructive file copying/moving in Python
View safeutil.py
#!/usr/bin/env python
"""
This is a script designed to be "safe" drop-in replacements for the
shutil move() and copyfile() functions.
These functions are safe because they should never overwrite an
existing file. In particular, if you try to move/copy to dst and
there's already a file at dst, these functions will attempt to copy to
a slightly different (but free) filename, to avoid accidental data loss.
