I’ve got to learn my decimals again, shame on me!
This is how you do it:
$ diff < (cd /path/one/ && find .) <(cd /path/two/ && find .)
The trick is using Sub shells and fake their output as a file. Then diff will just think you're comparing two files 
.
You have to cd to each folder in order to avoid showing the relative path in the output.
This is what you need, add it to your ~/.profile or any file that loads at your shell start up.
export TERM=xterm-color vim
Make syre to have syntax on in your ~/.vimrc
Several times in the past I needed to fetch a list of random objects. And Today I decided to make a Mixin class to add a get_random() method to my managers:
# -*- coding: utf-8 -*-
from random import sample
class RandomObjectManager(object):
"""
Manager Mixin to implement get_random() in your models.
You can override get_objects to tune the queriset
To use, define your class:
class MyManager(models.Manager, RandomObjectManager):
DEFAULT_NUMBER = 5 # I can change that
def get_objects(self):
return self.filter(active=True) # Only active models plz
class MyModel(models.Model):
active = models.BooleanField()
objects = MyManager()
Now you can do:
MyModel.objects.get_random()
"""
DEFAULT_NUMBER = 3
def get_objects(self):
return self.all()
def get_random(self, number=DEFAULT_NUMBER):
"""
Returns a set of random objects
"""
ids = self.get_objects().values_list('id', flat=True)
amount = min(len(ids), number)
picked_ids = sample(ids, amount)
return self.filter(id__in=picked_ids)
I’ve added this as a Django snippet and as a Gist.
$ mogrify -fill white -pointsize 16 -annotate +20+20 'If you\'re seeing this picture in Facebook, the person who uploaded it is an ass' -thumbnail 800x800 -quality 75 picture.jpg
Many times UI requires us to style differently widgets that have errors in a field instead or next to an error message.
Django provides a nifty .errors attribute to tell if a field of form has errors but you can’t affect the rendering of a widget with it.
And going through all your widgets can be a pain when you only need that ona extra HTML class:
<input type="text" class="errors" name="my_field" id="id_my_field"/>
I came up with this dirty snippet that gets the job done:
class MyForm(forms.Form):
"""
Extend from this form so your widgets have an 'error' class if there's
an error on the field.
"""
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
if self.errors:
for f_name in self.fields:
if f_name in self.errors:
classes = self.fields[f_name].widget.attrs.get('class', '')
classes += ' errors'
self.fields[f_name].widget.attrs['class'] = classes
Now you can either extend from that class or encapsulate in a method, add to all your __init__ on your forms or whatever.
The title is the string I was looking for when I needed do to this.
Since I use Google reader on my Netbook, I like to use fullscreen view to maximize pixels.
I just hate how slow it takes to switch between modes because of the silly ainmation of the toolbar/awesomebar which forces the browser to redraw the content after each pixel.
Well, here’s how to disable that. As expected, go to about:config and search for the string:
browser.fullscreen.animateUp
And set it to 0.
Since google just made their URL shortener service public, I decided I would start using it 
.
Going to the page and pasting a URL is too much work, Installing a firefox extension is too much bloat. So since I already use Ubiquity I figured I’d write a command to do so.
So here it is Goo.gl ubiquity script.
