Count the number of lines in a file with Ruby, without reading entire file into memory
- by smnirven
I'm processing huge data files (millions of lines each). Before I start processing I'd like to get a count of the number of lines in the file, so I can then indicate how far along the processing is. I am using Ruby, and because of the size of the files, it would not be practical to read the entire file into memory just to count how many lines there are. Does anyone have a good suggestion on how to do this?Read the article

Checking deployed port in ruby on rails application
- by john chan
Is there an elegant way to check which port you deployed a ruby on rails application using mongrel? I could not find a directive (i.e. such as #{RAILS_ROOT} which contains the root directory of the application) that I can use to perform a check. I need this to do a check since I am deploying the same application on different ports and I need the app to do different things according to the port that is being accessed. Any help would be appreciated, ThanksRead the article
