hi, I've got a quick question about Dir.glob. Does Dir.glob("**.rb") scan subdirs looking for *.rb files, or would you need to do Dir.glob("**/*.rb")?
<isaacs>
I could've sworn I've seen "**.rb" in examples and such, but it seems to only supprot the Bash4 style **/*.rb in mri 187 or 19

I have now gone down the path of configuring my rvm instance of to trust the certificate, but I can't figure out how to do it properly

Hi workmad3, that's also my strategy, but I am not sure about where ruby checks for certificates
<workmad3>
did you use openssl installed through rvm when you compiled ruby?
<workmad3>
or did you use a system installed openssl?
<ExxKA>
I downloaded dvm using homebrew
<ExxKA>
I am on Mac X
<ExxKA>
rvm*
<workmad3>
that doesn't answer the question

That's as close as I can come to an answer I am afraid, my other answer is, I do not know
wallerdev_ has quit [Quit: wallerdev_]
<ExxKA>
is there a way I can check for the answer to your question?
<workmad3>
right, so that means your first task is to find out what openssl installation your ruby is using ;
<k610>
can i call my gem "gtalk" or is that copyrighted ?
<ExxKA>
k610, I suppose it is used by google talk?
<workmad3>
ExxKA: well, first, have you ever installed openssl with rvm?
<workmad3>
ExxKA: which would mean you ran a command like 'rvm package install openssl' iirc, and you'd have done that before installing ruby
<ExxKA>
nope
<ExxKA>
I am quite certain i haven't
<workmad3>
ExxKA: right, so that means that you're dealing with the system installed openssl

there's also a configuration file detailing how the files are used, so I got the impression that I could override the certs by using these files

Hi. I am trying to use rcharts lib. But after installation from gem repository when I would like to use it in my code i am getting : 'ffi_lib': Could not open library 'lib.so': lib.so cannot open shared object file: No such file or directory. Any ideas ?
<shevy>
ner0x, it's probably somewhere in the RVM scripts that it sources from that file, rather than .bashrc
<browndawg>
ner0x: I think its because your bash_profile is sourced only at login, but your bashrc is sourced every time you open a new terminal.

Noobie question
<mwmnj>
I am trying to modify a gem and test the changes locally
<mwmnj>
So I have a file, test.rb that uses the gem, and the gem library repo cloned next to this file
<mwmnj>
How do I tell ruby I want to use the library I have cloned locallt?

I have a gem installed at /Users/matt/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/gems/1.9.1/gems/mygem
<shevy>
hmm so this is also rvm related
<mwmnj>
I am referencing that gem in a file, test.rb, with "require 'mygem'"
samphippen has quit [Quit: Computer has gone to sleep.]
<thestereobus>
I've got an interesting problem. I have 38k cities in a database and I have to send a message to each one via AMQP, perform some calculations, and update the city's timestamp in an Mongo database. The entire batch of cities has to be hit every 15 minutes.
<shevy>
I can tell you without rvm. this code would work for most gems
<mwmnj>
If I modify that gem at its location, deep within rvm, I can see those changes reflected when running test.rb
<thestereobus>
I've made a daemon and am fooling around with EventMachine
<shevy>
mwmnj without rvm, when I make a change to a gem, I reinstall the gem
apeiros_ has quit [Remote host closed the connection]
_alejandro has joined #ruby
<shevy>
(after the change)
<thestereobus>
but even using EM.defer the daemon eventually falls on its face and eats up CPU
<mwmnj>
shevy: My issue is that I want to modify that gem "locally"
<shevy>
this is the same issue I have. I solve it by simply reinstalling the gem, or more accurately, I use setup.rb actually
<mwmnj>
I have the gem repo cloned on my desktop
<shevy>
I have an alias to "r2", I run this and the gem/project is installed
<burgestrand1>
mwmnj: why are you doing this?
<thestereobus>
is EventMachine the right way to go about doing this?
burgestrand1 is now known as burgestrand
Virunga has joined #ruby
<Xeago>
thestereobus: why EM?
zigomir has quit [Quit: zigomir]
<shevy>
mwmnj, setup.rb came before gems were used, it installs things into ruby SITEDIR
<burgestrand>
thestereobus: perhaps try some worker solution, have you looked at sidekiq? EM is kind of complex to get right in itself, and requires special care about which libraries you use.
fooo has quit [Quit: leaving]
<shevy>
but with gems, it would only be one extra step, I could write a ruby script that does that
<thestereobus>
Xeago: mostly to ensure the timeliness of it… happening every 15 minutes
<thestereobus>
it's serving ads, basically
<shevy>
alias make_gem='gem build *.gemspec'
<shevy>
:D
<Xeago>
EM for repeating actions?
<thestereobus>
right
<Xeago>
isn't em used for event oriented models?
<sie>
shevy, What's your job?
<mwmnj>
burgestrand1: I want to modify the gem, test the changes, and then commit the changes to the repo it came from
<burgestrand>
Xeago: has a concept of timers and intervals
<shevy>
sie hmm? non-programming related, I just like ruby
<Xeago>
in any case, what burgestrand said, sidekiq looks promising for that
<thestereobus>
yeah. I'm doing an interval of 15.minutes / number of cities
<sie>
shevy, can has pm/
schaary has quit [Quit: Leaving.]
<shevy>
gotta reboot soon to change something in xorg-server
<burgestrand>
the only tricky thing about sidekiq would be the scheduling, but you can do that with sidekiq as well.
<shevy>
if I dont come back, I ran into problems :P
<thestereobus>
so it's doing like 5 ops every second or so
<Xeago>
there's a good railscasts about sidekiq
ryanlecompte has joined #ruby
iamjarvo has quit [Ping timeout: 256 seconds]
<burgestrand>
no need to use rails with sidekiq though, in case you aren’t already using rails
<thestereobus>
cool. I guess a message queue / worker solution might also work
<mwmnj>
shevy: so there is no way to reference that gem file directly via an absolute path or anything to my desktop?
akemrir has joined #ruby
<shevy>
mwmnj it's really nothing special, gems are only archives
<thestereobus>
I'm using rails in my mainline app but this daemon is just ruby + em + mongoid
<Xeago>
thestereobus: the cities list is relatively static, right?
<mwmnj>
The idea is to no have to navigate all the way within rvm any time I want to test these changes
<shevy>
mwmnj hmm? I use about 20.000 aliases, about 2000 of these are ruby related. I call my ruby scripts directly via scripts, and my projects in ruby
<thestereobus>
Xeago: yeah, it is. the daemon calculates the list on boot and it doesn't change
<burgestrand>
mwmnj: use bundler
<shevy>
ok need to kill xorg now...

tbh, I don't really get the problem, calculate the time it takes to do 1000 cities, and spawn enough workers and partition their work.. ?
<thestereobus>
so it's not really a messaging problem, I don't think
iamjarvo has joined #ruby
<thestereobus>
the main problem is that it has to pull the ad from the db and do some calculations, which are intensive and cause a synchronous queue to backup

you can (temporarily) override the location bundler fetches a gem from with the bundle command mwmnj
<ninegrid>
im trying to mockup some infinite scrolling using will_paginate over an array (to avoid actually creating a model and populating the database...) so, this works until i scroll to the bottom then im throwing 500 errors that the Fixnums in my array are not ActiveModel-compatible objects that return a valid partial path... what would be a quick work around to this?
<ninegrid>
the thing is, the intial page load pulls the correct number of per_page items from the array and renders them correctly with the partial, I can also visit page urls directly, ie ?page=20 and this works too... its just that when my javascript tries to fetch the next page that i hit this error

<thestereobus>
currently AMQP feeds a node.js daemon that sends pubsub messages to browsers via websockets. it is what will ultimately be sending the ads to the client.
<thestereobus>
using faye
<waxjar>
mwmnj is ruby a folder with a git repository in it? it's used for individual gems
<Xeago>
and every t-minutes your amqp gets filled right?
<mwmnj>
waxjar: yea, ruby has a folder "mygem" which is a got repo

It is what I am trying to install and modify
geggam has joined #ruby

Basically, when writing unit tests you have to come up with test values, in QuickCheck, you write conditions that must hold and it randomly comes up with millions of test cases for you, and it's very good at finding edge cases
<seanstickle>
Ah, that is a very nice explanation. I am unfamiliar with anything Ruby specific.
<seanstickle>
Which is quite different, but I share because combinatorial testing seems interesting.

so yeah bedouin, for ruby 1.9.3 this should be the same
<shevy>
in ruby 1.8.x it would not work

shevy: one guy committed the the 2nd part... which did not compile on another computer
<bedouin>
thanks shevy - so this is evolution of ruby (or rails?)

(because the other computer has shity ruby :D)

bedouin: The other computer is probably using 1.8, update it.
<flip_digits>
is there a way to break a sting up over multiple lines?
<TTilus>
flip_digits: just insert newline

bedouin: It's an upgrade to Ruby's syntax. When using symbols as keys to a hash, {:a => 1, :b => 2} can become the much nicer {a: 1, b: 2}.
<shevy>
bedouin it is a syntax change in ruby, rails influenced a lot of it though, but it was matz's decision

TTilus thanks
<TTilus>
flip_digits: then, of course, you get string with newlines in it
<TTilus>
flip_digits: whats the case?
<R3dy>
Does ruby have any way to do code signing?
<flip_digits>
TTilus I cant have newlines in the string. It's for a url
<TTilus>
flip_digits: if you have loads of formatted stuff, you might want to use heredoc
<TTilus>
flip_digits: ah, url

<R3dy>
maybe it goes by another name. I'm not getting much luck searching "Ruby Code Signing"
<TTilus>
flip_digits: and it is so long you wanna split it?
<flip_digits>
TTilus yes ti's more than 80 chars so...

Is there any way to get context-sensitive help in irb? For example in ipython I can type 'int?' and get the python docs on the int type

processing a csv in ruby, creating integer ranges for each row and each item in the instance dumped into redis…sooooo slow :(

dobbymoodge: I would recommend that you try: https://rvm.io/ there is the guide on how to install and use... you will get latest version of ruby with that... and don't forget to check the requirements for rvm
