Now I would like to update/change some of these items when a particular item is clicked, while still displaying the menu. How can I prevent the taskbar menu from disappearing after clicking an item? The only method I've found that could be us...

Basically I need to scrape a lot of information from a website that moniters the European Parliament. Here is an example of how the url of one site...
I'm researching software components to use in a future development of a business logic web application. It's gonna be written in Python and we are targeting SQLAlchemy as ORM. The app will be used by other software apps via a REST-like interface over http, possibly using web.py for that part. For debugging, maintenance, etc we need to d...

I'm trying to match a "#" followed by letters if and only if it's preceded by newline, whitespace or is the first character in a string. The first two I've done, but I'm having a hard time matching if it's the first character in a string. I'm trying to find a use for '\A', but it doesn't work to just add it to the class containing newlin...
I'm currently going through a few tutorials to get myself up and running on Python, but I seem to hit the same problem a few times. The tutorial I'm currently following is Aloha.py in Introduction to Simulation by Norm Matloff. The problem I'm hitting seems to be in the following code: import random, sys class node: # one object of thi...
If I want to detect perspective distorted objects (e.g rectangles) and calculate the correction transformation, what would be a good method? For example, I have a lot of photos of papers lying on a flat surface (the photos are shot from an angle), and I want to correct the perspective and crop them. I am thinking of using the OpenCv Py...
In python, I know that looking up a locally scoped variable is significantly faster than looking up a global scoped variable. So: a = 4 def function() for x in range(10000): <do something with 'a'> Is slower than def function() a = 4 for x in range(10000): <do something with 'a'> So, when I look at a cla...

I have a Numpy array that looks like >>> a array([[ 3. , 2. , -1. ], [-1. , 0.1, 3. ], [-1. , 2. , 3.5]]) I would like to select a value from each row at random, but I would like to exclude the -1 values from the random sampling. What I do currently is: x=[] for i in range(a.shape[0]): idx=numpy.where(a[i,:]>0...
In Google App Engine, an entity has a Key. A key can be made from a path, in which case str(key) is an opaque hex string. Example: from google.appengine.ext import db foo = db.Key.from_path(u'foo', u'bar', _app=u'baz') print foo gives agNiYXpyDAsSA2ZvbyIDYmFyDA if you set up the right paths to run the code. So, how can one take ...
Hi everyone. I'm trying to read a line from a static file and insert it into a template in Google App engine using the Webapp framework. However, the line does not render, not matter what I try. Is there something that I'm overlooking? main.py: def get(self): ... question = randomLine("data/questions.csv") data = question....
Are there any libraries that provide 3D polyhedra, and support calculating the intersection of two polyhedra? If it makes a difference, the polyhedra I want to model do not have 'holes' in them. The focus would be on correctness first and speed a close second! Ideally this library would: have existing tidy python bindings be free-st...
I'm trying to write a shell script that will make several targets into several different paths. I'll pass in a space-separated list of paths and a space-separated list of targets, and the script will make DESTDIR=$path $target for each pair of paths and targets. In Python, my script would look something like this: for path, target in zi...
I'm trying to use Dumbo/Hadoop to calculate TF-IDF for a bunch of small text files using this example http://dumbotics.com/2009/05/17/tf-idf-revisited/ To improve efficiency, I've packaged the text files into a sequence file using Stuart Sierra's tool -- http://stuartsierra.com/2008/04/24/a-million-little-files The sequence file uses m...

Consider a tier of N-many subscribers, all connected to a direct exchange using identical queue name and routing key values. This creates a load-balanced system where an inbound message is send round-robin to 1 of the subscribers. This works very well for dealing with scale-out issues as more subscribers can be added as load increases ...
