var varName = function funcName() {}
what is the difference between
var a = function() {}
and
var a = function b() {}
The latter, b is undefined?

Adjusting a RegEx to require 2 digits after an optional decimal?
Adjusting a RegEx to require 2 digits after an optional decimal?
I believe I've found the "perfect" Regular Expression to check against for
currency in jQuery Validate, except it seems to allow the user to put a
single lone decimal at the end or a decimal with a single digit after.
Matches: 700. and 3.0
The Regex:
^\$?([1-9]{1}[0-9]{0,2}(\,[0-9]{3})*(\.[0-9]{0,2})?|[1-9]{1}[0-9]{0,}(\.[0-9]{0,2})?|0(\.[0-9]{0,2})?|(\.[0-9]{1,2})?)$
I've been playing with it in http://gskinner.com/RegExr/ but can't seem to
modify it in the right places to fix my decimal issue.
Currently it matches everything I need it to:
700,000
700,000.00
700000

Batch editing of csv files with Python
Batch editing of csv files with Python
I need to edit several csv files. Actually, most of the files are fine as
they are, it's just the last (41st) column that needs to be changed. For
every occurrence of a particular string in that column, I need it to be
replaced by a different string; specifically, every occurrence of 'S-D'
needs to be replaced by 'S'. I've tried to accomplish this using Python,
but I think I need to write the csv files and I'm not quite sure how to do
this:
import os
import csv
path=os.getcwd()
filenames = os.listdir(path)
for filename in filenames:
if filename.endswith('.csv'):
r=csv.reader(open(filename))
for row in r:
if row[40] == "S-D":
row[40] = "S"
Any help? Also, if anyone has a quick , elegant way of doing this with a
shell script, that would probably be very helpful to me as well.

Cocoa programming app with multiple view
Cocoa programming app with multiple view
I'm programming a simple application for Mac OSX, using cocoa framework. I
don't know how sending messages between 2 different view in the same
windows. My app have 2 view : first view that contains 1 form and 1 submit
button, second view that contains a WebView that loads a flash.
The steps to do are :
1) At start do a control and based on the result it shows view1 or view2
2) If view1 is visualized, on the submit action, based on inserted data,
view1 disappears and view2 appears.
I would know how build window and views and how manage this logic. Thanks.

How do I configure Chef Solo to install Nginx on a new Vagrant box?
How do I configure Chef Solo to install Nginx on a new Vagrant box?
I'm new to Chef and the documentation (even the home page of their
website) makes my head spin. I'm not even sure if I'm using it for the
correct purpose.
My intent is to setup a Vagrantfile that tells Chef Solo to automatically
install some software automatically when I spin up a new box. That is one
of Chef Solo's intended uses, am I correct?
I'm not really sure if that qualifies as one of "the hardest
infrastructure challenges on the planet", but whatever.
My first goal is to get Chef Solo to install nginx for me. In my project,
I've cloned the cookbook for nginx:
$ git clone https://github.com/opscode-cookbooks/nginx.git cookbooks/nginx
I edited my Vagrantfile to look like this:
Vagrant.configure("2") do |config|
config.vm.box = "opscode-ubuntu-1204"
config.vm.provision :chef_solo do |chef|
chef.add_recipe "nginx"
end
end
When I ran vagrant up, I got some errors that some cookbooks weren't found
(build-essential, apt, etc), so I cloned them from their appropriate
repos. Now, when I vagrant up, I'm getting this output:
