<ryanf> Wroathe: it's really not that big a deal. if that somehow ends up being a performance bottleneck you could try writing your own helper using index repeatedly with the offset parameter
<ryanf> I'm not at all sure it would be faster though
<ryanf> worrying about micro-optimizations like that is silly

<Wroathe> Milossh it's not that hard...
<Wroathe> They literally give you step by step instructions
<Milossh> Wroathe, I just removed what I installed(passenger-install-apache2-mod)
<Wroathe> What part are you stuck on?
<Milossh> and installed my distro's lib: ubutu, libapache2-mod-passenger
<Wroathe> it should be as simple as gem install passenger; passenger-install-apache2-module;
<Milossh> Wroathe, I's stuck on getting some errors that PassengerRoot is not correct as it couldn't find spawn server, then I created symbolic links to files I found, and then it didn't complain about anything, but didn't work, eirher
<Wroathe> Reinstall your gem
<Wroathe> Do those two commands again
<Wroathe> What linux distro are you using?
<Milossh> Wroathe, ubuntu
<Wroathe> Natty Narwhal?
<Milossh> yep
<Wroathe> Are you using RVM?

<Wroathe> So what's the problem now?
raffivar [raffivar!~raffivar@77.125.244.236] has joined #ruby
<Milossh> Wroathe, no worries. So, I basically have apache saying it has loaded passenger module, and I have a vhost pointing to a directory where I have passenger_wsgi.py set up, but it's not showing my website, but directory with files

<CodeZombie> hey guys, so I've been trying to learn more ruby, not just rails... and coming from a php background, I'm more inclined to automatically lean towards blocks, and loops. Here's an example, would there be a way to refactory this down more? I know it's already pretty simple, but I'm mostly just curious.

<robyurkowski> what's happening is that when you just assign it to a single array, you're accessing a particular character by using a second index
<robyurkowski> i.e. so privs[0] returns "update,insert", but privs[0][0] returns "u", or perhaps a character code

<rockets> Here's a silly question, why is it that I can use gets.chomp to set the value of a variable, e.g. blah = gets.chomp, but if i start a file with ARGV = one, two, three, it breaks gets.chomp later and I have to use STDIN.gets or something like that. I realize that gets is now "referencing" argv in some way, but I don't really know what that means or why

<td123> and it lists it on the site, but locally, gem search -r tagurit also returns nothing
<Okasu> do you know any good book with excercises in ruby?(except rubyquiz)

<D[4]ni> wait a sec, debian archives also still have 0.8.7?

<UdontKnow> D[4]ni: debian has 2 branches you can choose from: stale and unstable :)
<D[4]ni> in this case it's more of a question to the redmine devs, sorry
<Okasu> >stale
<Okasu> lol
<Okasu> right you are
<UdontKnow> Okasu: the sad truth is, I've been running this joke since before they released potato
<UdontKnow> what was the name of that release? hmmm
<D[4]ni> anyway, if i try and install rake using "gem install rake -v=0.8.7", trying to use it will result in "/usr/bin/rake: file or directory not found"
<UdontKnow> Okasu: actually, I said that when hamm was the release, in 98
<shevy> D[4]ni, that's the disadvantage on being a slave to the distribution

<multi_io> hm, my r1.8 script contains a block {|(x,)| ...} to capture the first element af the first argument to the block (which must be an array)
<multi_io> this syntax is no longer supported in 1.9?

<multi_io> e.g.:

<multi_io> in the block, x is the respective scanned values, as a string.
