2009-01 NSArray+Functional.h

This is a category to add Python like map, filter and reduce methods to Cocoa NSArray:

@interface NSArray (Functional)

- (NSArray *)filterUsingSelector:(SEL)aSelector, ...;
- (NSArray *)mapUsingSelector:(SEL)aSelector, ...;
- (id)reduceUsingSelector:(SEL)aSelector;

@end

You can then program in functional style:

NSArray *a = [NSArray arrayWithObjects:@"a", @"ab", @"abc", @"bc", @"c", nil];

NSArray *x = [a filterUsingSelector:@selector(hasPrefix:), @"a", nil];
NSArray *y = [a mapUsingSelector:@selector(uppercaseString), nil];
NSArray *z = [a reduceUsingSelector:@selector(stringByAppendingString:)];

Results:

x: (a, ab, abc)
y: (A, AB, ABC, BC, C)
z: aababcbcc

Read the blog post talking about it: Map, filter and reduce in Objective-C/Cocoa.

2008-03 utis.py

SpotLook tracks use UTIs to know what kind of file to search.

In order to prepare the defaults tracks, I did search for UTIs lists on the web.

I put the most interresting links in SpotLook FAQ.

One ressource was especially useful, it's an autogenerated graph of the system UTIs.

Sadly, the author did not post the ruby script he wrote to generate the tree.

It immediately made me think of how I would write such a script.

So here's a script, obviously written in my scripting language of choice :)

It does not build up the UTIs hierarchy (since it's not what I need) but it lists the UTIs used by Spotlight importers on your system.

2007-01 utf8tolatin1.py

Convert utf-8 text into iso-latin-1 by minimizing characters loss.

utf8tolatin1.py.txt

Faites par exemple un coper-coller de la page d'accueil du Monde et collez-la dans SubEthaEdit. Vous êtes obligés d'utiliser l'encodage utf-8. Vous pouvez le convertir en iso-latin-1, mais les caractères qui ne sont pas représentables en iso-latin-1 seront remplacés par des '?'.

Quand on essaie de faire une telle conversion, les différents langages ou logiciels proposent généralement le choix entre :

Or ce que je veux le plus souvent c'est convertir en minimisant les pertes, de manière à ce que le texte reste lisible, en convertisant par exemple les caractères "oe", "euro", etc.

Le script utf8_to_latin1.py permet de faire ça. Notez que si vous tombez sur un caractère impossible à convertir, le script lèvera une exception. Il suffira alors de rajouter la conversion souhaitée dans le script.

$ python utf8tolatin1.py mon_texte_utf8.txt > mon_texte_latin1.txt

2006-08 flickrgallery.py

Built a web page with Flickr sets photos showed in big.

flickrgallery.py.txt updated 2009-06-08

Am I the only one to find that Flickr sets are ridiculously small and uncomfortable to browse?

Yes, I know, you could use Pywebpics to make your own gallery on your own server.

But photos take place and it might be more convenient to store them on Flickr.

flickrGallery is a quick Python script that does the following:

input: a title string

output: an html file showing the photos set with a normal size

example: before after

2009-08-03 this script now works online at http://phlickrgallery.appspot.com/.

2006-04 airportkey.m

AirportKey can convert a WEP password from ASCII to hexadecimal Airport "equivalent network password" (Apple proprietary hash) without being connected to the Aiport base station. It uses Apple private framework Apple80211.framework.

airportkey_src.zip

$ airportkey 
Translate a string into a 40 or 104-bit Apple hashed WEP key.
usage: airportkey  
        password:       the ASCII WEP password
        use104bits:     0 for 40 bit key and 1 for 104 bit key 
        version: 0.1

2006-02 pywebpics.py

Quickly create and update a web photo gallery.

pywebpics.py.txt

See an example gallery.

Typical scenario

  1. create a project $ pywebpics my_project
  2. put some photos in my_project/source
  3. run pygallery again $ pywebpics my_project
  4. your gallery is ready!
  5. add some more photos in your source folder
  6. run pygallery again
  7. the latest photos are added to your gallery!
  8. edit my_project/config.txt
  9. run pywebpics again
  10. write your ftp settings in my_project/config.txt
  11. run pywebpics with the -upload option $ pywebpics -upload my_project
  12. your gallery is online!
  13. add some more photos in your source folder
  14. run pygallery with the -upload option
  15. your local and remote galleries are updated!

I personally find the concept very original and practical. A gallery is stored in a project directory that contains all the photos as well as a config file. To add new photos, you just need to add them in the source directory and run the script on the project directory, and every steps will be done automagically.

2005-10 myftp.py

Le Boggle is a letter game edited by Parker. The players must find as many words as they can in a 4×4 letters grid (or more) in three minutes. See the official rules.
