xrange with float steps - Python

The great thing about this code, is that the definition its a generator. (You can easily identify the keyword yield)

def drange(start, stop, step): r = start while r < stop: yield r r += step >>>i0=drange(0.0, 1.0, 0.1) >>>["%g" % x for x in i0] ['0', '0.1', '0.2', '0.3', '0.4', '0.5', '0.6', '0.7', '0.8', '0.9', '1'] >>> source

How to uninstall XCode4 from Mac OS X Lion

So i had an old version of XCode on my computer, and i tried upgrading it with the new mac app store, and it didn’t work. I wanted to uninstall it and then reinstall it using the app store, but they of course don’t have an option to UNINSTALL apps using the app store
Google tells me to just delete the app and then you can click ‘install’ again on the purchases tab in the app store, but since this is xcode, you can’t just drag an application to the trash. You have to run a command using Terminal. So, open terminal and type:

sudo /Developer/Library/uninstall-devtools –mode=all

The directory MIGHT be different, but for me it installed it to /Developer. Anyway, it should list all the packages and then say it deleted them. I restarted my mac just to be safe.
THEN, if it STILL says that xcode is installed, you need to delete the installer from /Applications (different from the Applications folder in your home folder). Go Macintosh HD/Applications and there should be a file called “Install Xcode…

Fix file permissions in Mac OS X

A few days ago I copied a bunch of files/folders from an external NTFS formatted hard drive to my MacBook. The files where copied ok, but the permissions where messed up.

How did I fix them? With this simple command:
$ chmod -Rv u=rwx,g=rx,o=r username path_to_base_folderIt recursively goes through all files and folders and fix their permissions. Source!

Read and Write NTFS partition under Snow Leopard

This is experimental, and known to be unstable, use at your own risk.
You need to modify /etc/fstab file to mount NTFS partitions for read and write.
First, uninstall NTFS-3G/Paragon if installed.Open Terminal
run diskutil info /Volumes/volume_name and copy the Volume UUID.
Backup /etc/fstab if you have it (shouldn't be there in a default install). Run sudo vim /etc/fstab and write:
UUID=paste_the_uuid_here none ntfs rw
or
LABEL=volume_name none ntfs rw
(if you don't have UUID for the disk).
Repeat for other NTFS partitions.Restart your system.Thats all!

Resize images with Preview (Snow Leopard)

Image
Alternative 1 A Quick way to resize images in batches could be find that Preview has that functionality. Open the whole batch of images in Preview; the images will all open in the same window with thumbnails visible in the sidebar.
Select all of the thumbnails in the sidebar (with Command-A, or click the first and then click the last while holding Shift). Next, from the Tools menu, choose Adjust Size. You’ll be presented with a dialog containing options to resize to all the common 4:3 and 16:9 screen sizes, as well as the option to define custom dimensions. Images are scaled proportionately and resampled by default. snow leopard preview image resize
Save the resized images, and you’re done! Preview will prompt you to save any changes if you attempt to close the window. Alternative 2 You can also use sips on the command line: sips -Z 1024 *.jpg will resample to a max of 1024 px for the long edge. Note that sips rewrites images in place, so you should do this on a copy if you care.

Playing DVDs Ubuntu 10.04

Playing DVDs
In order to play DVDs you must install some additional software. Unfortunately, DVD support cannot be provided by default in Ubuntu due to legal restrictions in some countries.

Read about restricted formats before following the instructions below. There are some legal issues that you should be aware of.
Install the libdvdnav4, libdvdread4, gstreamer0.10-plugins-bad and gstreamer0.10-plugins-ugly packages.
If you would like to play encrypted DVDs, press Applications → Accessories → Terminal and type the following into the screen which appears, followed by the Enter key:
sudo /usr/share/doc/libdvdread4/install-css.sh
Enter your password if prompted. The libdvdcss2 package will be downloaded and installed from a website.
Insert a DVD into your drive. It should open automatically in the Movie Player.

Dictionary of Methods/Functions (Python)

Construct a dictionary with String (or other) keys and unbound methods or functions as values. During execution, use the string keys to select which method or function to execute. Can be used for simple parsing of tokens from a file thru a kind of object-oriented case statement.

import string def function1(): print "called function 1" def function2(): print "called function 2" def function3(): print "called function 3" tokenDict = {"cat":function1, "dog":function2, "bear":function3} # simulate, say, lines read from a file lines = ["cat","bear","cat","dog"] for line in lines: # lookup the function to call for each line functionToCall = tokenDict[line] # and call it functionToCall()
It's embarrasingly simple really, but I use it a whole lot. Instead of functions, methods might also be used (self.method1), remember to follow the binding rules if you use methods dir…

Es impresionante como en todos lados en internet hay una sinopsis errada de esta película..
O nadie la vio, o nadie la entendió, pero ni wikipedia da el dato correcto.

La película va así: En el año 2092 Nemo Nobody es el último hombre que va a morir de viejo, en una época donde ya todas las personas son inmortales. Nemo tiene 117 años, y se está acercando lentamente a sus últimos momentos de vida. Durante la película se nos van revelando recuerdos (o algo así) de este anciano que bien podría estar completamente confundido, o ver todo mucho más claram…
