I am under the impression that the number of mappers is a result of the inputsplits produced. I could run subsequent jobs, one for each string, but it seems kinda... messy?

• Sentence recognition and ability to answer with another sentence

  - by terabytest

  Hi. I'm looking into sentence recognition to make a program that should play voice clips from the game Team Fortress 2. I have .wav files and text files containing the transcription for every sound. What I'd like to make is a system that makes two characters of the game talk to each other (trough playing sound clips), and each one recognises the sense of what the other is saying and tries to answer with another of the available sound clips (trying its best to fit the sense of what it's trying to say) Is that possible in any way?

• Most performant way to check how many objects are referenced by an to-many relationship in Core Data

  - by dontWatchMyProfile

  Lets say I have an employees relationship in an Company entity, and it's to-many. And they're really many. Apple in 100 years, with 1.258.500.073 employees. Could I simply do something like NSInteger numEmployees = [apple.employees count]; without firing 1.258.500.073 faults? (Well, in 100 years, the iPhone will easily handle so many objects, for sure...but anyways)

• How often is authenticated SOCKS5 used as an HTTP proxy in organizations?

  - by brainsnorkel

  I'm wondering how frequently organisations use SOCKS5 as their web proxy protocol over, say, HTTP or authenticated HTTP proxies. Should an application even bother supporting SOCKS5 as an HTTP proxy? What percentage of organisations use SOCKS as a HTTP proxy? If you work in an organisation where you use SOCKS5, particularly authenticated SOCKS5, as the means of achieving HTTP Internet connectivity I'd be interested in hearing your thoughts. If you have experience with requirements for SOCKS5 proxies in your software I'd like to hear your thoughts too.

  Let's say that I have the following text: in = "one aaa two bbbb three cccc" I would like to parse this into a group of variables that contain notworking = ["one", "two", "three"] v1,v2,v3 = in.split(notworking) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml

• Need a TV/Movie API with associated trailers

  - by Paul

  Looking for a movie/TV API that offers previews (trailers), via widgets or links, as well. I know IMDB has an API, but it only has metadata. Internet Video Archive also has an API, but, well, lets just say they seem a bit incompetent. I could use YouTube, but I'd get a lot of cruft and unofficial results. Anyone else have any ideas?
