Objective reasons for using Python or Ruby for a new REST Web API | 1,850,743 | 2 | 6 | 3,675 | 0 | python,ruby,web-services,api,rest | I think they are fairly evenly matched in features. I prefer Python, but I have been using it for over a decade so I freely admit that what follows is totally biased.
IMHO Python is more mature - there are more libraries for it (although Ruby may be catching up), and the included libraries I think are better designed.... | 0 | 0 | 0 | 0 | 2009-12-05T00:55:00.000 | 7 | 0.057081 | false | 1,850,640 | 0 | 0 | 1 | 5 | So this thread is definitely NOT a thread for why Python is better than Ruby or the inverse. Instead, this thread is for objective criticism on why you would pick one over the other to write a RESTful web API that's going to be used by many different clients, (mobile, web browsers, tablets etc).

Why not spend as couple of days with each? See how far you can get with a simple subset of the problem, then see how you feel.

Objective reasons for using Python or Ruby for a new REST Web API | 1,850,701 | 6 | 6 | 3,675 | 0 | python,ruby,web-services,api,rest | I would say the important thing is that regardless of which you choose, make sure that your choice does not leak through your REST API. It should not matter to the client of your API which you chose. | 0 | 0 | 0 | 0 | 2009-12-05T00:55:00.000 | 7 | 1 | false | 1,850,640 | 0 | 0 | 1 | 5 | So this thread is definitely NOT a thread for why Python is better than Ruby or the inverse.

Ruby Quiz for Python | 1,852,706 | 1 | 2 | 463 | 0 | python | At the risk of stating the obvious, why not just do the rubyquiz examples in python. Those exercises as well as others aren't tied to a language - you're just as well off just doing projecteuler problems in python rather than searching for python-specific puzzles. A puzzle is a puzzle a language is just a tool to solve... | 0 | 0 | 0 | 1 | 2009-12-05T06:52:00.000 | 2 | 0.099668 | false | 1,851,396 | 0 | 0 | 1 | 1 | Is there a blog/forum/listserv that is equivalent to RubyQuiz.com for the Python language? |
Writing a Faster Python Spider | 1,853,865 | 3 | 6 | 7,091 | 0 | python,web-crawler | You waste a lot of time waiting for network requests when spidering, so you'll definitely want to make your requests in parallel. I would probably save the result data to disk and then have a second process looping over the files searching for the term. That phase could easily be distributed across multiple machines ... | 0 | 0 | 1 | 0 | 2009-12-05T22:28:00.000 | 6 | 0.099668 | false | 1,853,673 | 0 | 0 | 1 | 3 | I'm writing a spider in Python to crawl a site.

Writing a Faster Python Spider | 1,854,592 | 0 | 6 | 7,091 | 0 | python,web-crawler | What Adam said. I did this once to map out Xanga's network. The way I made it faster is by having a thread-safe set containing all usernames I had to look up. Then I had 5 or so threads making requests at the same time and processing them.
