Not sure whether this is faster but it's shorter:

dirs = Hash.new do |h,dir|
  Dir.chdir dir { system 'git pull' }
  h[dir] = true
end

Dir[File.join(File.expand_path("~/programming/repos"), "**",
"*.git")].each do |gf|
  dirs[File.basename(gf)]
end

Alternative

require 'set'

dirs = Set.new

Find.find File.expand_path("~/programming/repos") do |f|
  dir = File.dirname f

  if File.file? f and /\.git$/ =~ f and dirs.add? dir
    Dir.chdir dir { system 'git pull' }
  end
end

Cheers
