DevDays Austin: Eric Jones on Python posted January 7, 2010
This is content taken from the 2009 StackOverflow DevDays conference in Austin, Tx.This presentation could actually be split into two different talks. Unfortunately, Eric only had fifty minutes to cover both Python and NumPy.
The Python part of Eric’s talk dealt with a very elegantly written spell check example written by Peter Norvig (copied below).
This Python code not only finds spelling errors in a given input file, it also guesses what you intended to type and suggests correctly spelled words to replace the erroneous word.
Here is the code that was discussed in Eric’s talk so you can follow along with the audio.
import re, collections def words(text): return re.findall('[a-z]+', text.lower()) def train(features): model = collections.defaultdict(lambda: 1) for f in features: model[f] += 1 return model NWORDS = train(words(file('big.txt').read())) alphabet = 'abcdefghijklmnopqrstuvwxyz' def edits1(word): s = [(word[:i], word[i:]) for i in range(len(word) + 1)] deletes = [a + b[1:] for a, b in s if b] transposes = [a + b[1] + b[0] + b[2:] for a, b in s if len(b)>1] replaces = [a + c + b[1:] for a, b in s for c in alphabet if b] inserts = [a -
DevDays Austin: Jonathan Johnson on iPhone Development posted January 6, 2010
This is content taken from the 2009 StackOverflow DevDays conference in Austin, Tx.Jonathan gave a very nice introductory presentation on developing applications for the iPhone. The live code example was a great deomonstration on how to get a new app up and running quickly. It seems that Apple really did their homework when creating the iPhone development tools.
One disheartening part of Jonathan’s talk dealt with the current state of the iPhone App Store. As most of you probably know, the App Store has been built on this $0.99 eco-system where it’s really hard to sell iPhone apps that cost more than a dollar. Unfortunately, this means that a company may never fully re-coup the costs of developing an application if it takes them too long to create, much less turn a profit. Does this mean there aren’t going to be any new and awesoeme apps coming out for your iPhone in the future? No. But, the current state of the app market may cause developers looking to get into the iPhone development market have second thoughts.
Overall, a great talk by Jonathan and it was very informative for those of us who have never developed anything for the… Read the rest

DevDays Austin: Peter Mourfield on ASP .NET MVC posted January 5, 2010
This is content taken from the 2009 StackOverflow DevDays conference in Austin, Tx.In this presentation, Pete gives an interesting talk on the ASP .NET MVC architecture. This talk offers a fresh alternative to anyone currently working on ASP web forms. Also, the point of entry for developing ASP .NET MVC applications is much smaller for developers currently working in MVC frameworks such as Ruby on Rails, Palm Mojo, or even Django.
The Model View Controller (MVC) framework allows for the separation of the presentation and business logic and allows developers to change one without affecting the other.
The idea of MVC is nothing new, but it’s nice to see the mainstream web frameworks (and even mobile development frameworks) adopt this methodology.
If you are interested in learning more about MVC architectures or are curious about getting started with ASP .NET MVC then check out Pete’s talk. You won’t regret it.
