• Audio processing libraries for Ruby?

  - by J. Pablo Fernández

  Any recommendation on libraries to do audio processing in Ruby. I need to do the following two tasks: Find silences, for which I'm happy to just be able to iterate over each sample in the wave. Cut and paste pieces of wav files to form a new wav file. Convert wav to mp3, which I will probably leave to lame anyway. I'm looking for the equivalent of NAudio, a C# library.

• Writing a file shredder in python or ruby?

  - by pmilb21

  In the effort to learn python and/or ruby, I was wondering how a file shredder would be implemented? I would like it to take in a file as an argument and then employ an algorithm to make that file unrecoverable. Would possibly add the support for multiple files or even whole directories later.

• Best practices for handling binary data in Ruby?

  - by StackedCrooked

  What are the best practices for reading and writing binary data in Ruby? In the code sample below I needed to send a binary file using over HTTP (as POST data): f = File.new("resp.der", "r") # binary file begin while true out.syswrite(f.sysread(1)) # out is an output stream (type IO) end rescue EOFError => err puts "Sent response." end While this code seems to do a good job, it probably isn't very idiomatic. How can I improve it?

• Automatically download files in Ruby

  - by Obinna

  I'm trying to write a ruby script which automatically downloads some files from some server ever 30-45 minutes (to prevent overload) as long as my computer is turned on. It's possible that my computer might be turned off at some point, but the download should resume (probably re-download the current file). I already have the file list but I can't figure out how to make such a script to run autonomously. What are some ways I can do this?

• Methods in Ruby: objects or not?

  - by Mladen Jablanovic

  Inspired by this discussion, after some googling I wasn't able to find an answer to a pretty simple question regarding methods in Ruby: are they objects or not? There are different opinions here and there, and I would really like to hear, let's say, an in-depth explanation. I'm aware of Object#method method, which takes a method name and returns a Method instance, but, on the other hand, there's a similar thing you can do with blocks to make them into Proc instances, and blocks aren't objects, so what makes methods any different?

• Ruby: Allowing a module to have settings

  - by JP

  If I'm building a library in ruby, what's the best way to allow users of the library to set module-wide settings that will be available to all sub classes etc of the library? A good example would be if I'm writing a library for posting to a webservice: TheService::File.upload("myfile.txt") # Uploads anonymously TheService::Settings.login("myuser","mypass") # Or any other similar way of doing this TheService::File.upload("myfile.txt") # Uploads as 'myuser' The idea would be that unless TheService::Settings.logout is called then all TheService operations would be conducted under myuser's account. Any ideas?
