I understand how ETag or Last-Modified works (Validation) - the client will ALWAYS still hit the server, and the server needs to validate the date or etag against the current val...
I want to test whether a equals 1 or 2 I could do a == 1 || a == 2 but this requires repeating a (which would be annoying for longer variables) I'd like to do something like a == (1 || 2), but obviously this won't work I could do [1, 2].include?(a), which is not bad, but strikes me as a bit harder to read Just wondering how do to ...
Untill now I used soap4r as my SOAP-client with Ruby 1.8.x, but now I am moving on to Ruby 1.9.x. Unfortunately soap4r doesn't work with Ruby 1.9.x I just get the "invalid multibyte escape" which seems not solvable, mostly because the soap4r gem wasn't updated since 2007, so I assume the project is dead. I had a look at handsoap but the...

Do i need to d...

Is there a more elegant way of doing this logic in ruby a = nil #=> obviously 'a' can have value but I am just setting it nil to make the eg more clear b = a unless b b = "value" end so that we have the value of b set in the end.

File.open(filename).each_line.with_index do |line, idx| if idx > 0 ... end end # This is what I want to do but I don't need drop(1) to slurp # the file into an array. File.op...

The terminal doesn't return to the way it was before, but takes on some of the properties of the colorscheme I was using in Vim. This doesn't happen if I'm u...
