<Porfa> i'll try to explain this the best way i can… i was learning mechanize fill some forms, but i guess some of them are in .js and mecha can't handle that.. so someone was nice enough to redirect me to watir because it can run in console pretty lightly (i just have access to a linux terminal no X windows system) so i went on to install watir gems and the headless gem, the same way i installed every other gem in my life
tester__ has quit [Remote host closed the connection]
<Porfa> and when i got to require the headless gem, it spits out errors, so I'm really clueless on what you are saying about showing the code.. there is no code at all at this point i guess, just trying to install a gem then process to learn how to use it

<Porfa> Done installing documentation for headless after 0 seconds
<Porfa> 1 gem installed
<Radar> Fun.
<Radar> So install a Ruby using chruby + ruby-install and then see how you go after that.
<nofxx> or just create a ~/.gemrc file with:

<sevenseacat> I think you've been looking at this too long, when 'access denied' is not a meaningful error
<sevenseacat> one of your credentials is wrong. I don't know which.
<z1haze> right.. access denied because it was unable to connect, the credentials were wrong, etc
<z1haze> no it ISNT
<sevenseacat> no, not because it was unable to connect

<z1haze> the credentials are not wrong.
<z1haze> please stop trying to throw the blame on that
<sevenseacat> there's literally nothing else to put the blame on
<sevenseacat> its a single line of code that returns an access denied error
<z1haze> i can login with the cli from here remotely with the exact same copy and paste credentials.
<sevenseacat> show us?
<z1haze> show you want? my credentials?
<z1haze> wtf?
<sevenseacat> no, show us you connecting with them
<z1haze> sure
<zenspider> the client defaults to port 0 if you don't specify
<z1haze> but somehow it magically connected on 3306.. i dunno how
<zenspider> unless someone down the channel interprets that as "not set" and changes it to the port you mention above, I would start there

<z1haze> i just showed you that i logged in fine
<sevenseacat> configure your things both the same way.
<sevenseacat> yes, with a hostname, not an IP
<zenspider> z1haze: please go look at the server logs to see what it says about connection attempts
<z1haze> where woudl those be? on centos?
<z1haze> ill find , hang on

<glen> acutally don't know if <<EOF and <<"EOF" have difference in shell. afaik not
<jhass> I'm glad ruby isn't shellscript though

<vali> I have a problem regarding an output (cassandra) that I'm using in logstash. The problem is related to a timestamp that I'm trying to insert into cassandra. More exactly stuff like 2015-08-27T13:03:50.400Z fails to be parsed as a timestamp and gets set to "1970-01-01 00:00:00"
<vali> if I look at the code, the timestamp is parsed with Cassandra::Types::Timestamp.new(Time::parse("1970-01-01 00:00:00"))
<vali> and ideas on what I could do to make it work as expected ?

<zenspider> iso8604 should parse great. more importantly, don't use Time.parse if you know the format as it is terribly terribly slow
<vali> zenspider: what could I use ?
<jhass> >> require "time"; Time.iso8601("2015-08-27T13:03:50.400Z")

<Travis-42> I’m trying to understand the changes ruby 2.2 made to hash keys that are string. prior to 2.2, env[“PATH_INFO”.freeze] would be faster and reduce memory allocations compared to env[“PATH_INFO”] multiple times across a project. Am I understanding correctly that in 2.2, ruby does this automatically now?

<Ox0dea> Hm? I think he wants the user to be able to enter an expression at the end of the line, and then replace that expression with the answer when they press Enter.
<jhass> so not much gained by jump back vs jump a line up
<jhass> I think they just want to append the answer

<Travis-42> I'm trying to better understand ruby memory allocation: When "5.times { foo = 6 }" is run, ruby will use up 5 object slots (a new one on each iteration), unless GC runs during the iteration, right (in which case it'll reuse the "freed" slots)? E.g. for something like rails’ find_each do be more efficient than all.each, it relies on GC running at some point? Or am I not understanding?

<Travis-42> well, I’m trying to better understand why find_each in rails (which creates 1000 item arrays) is much better for memory than all.each — so suppose something like 100_000_000.times { foo = “a string” }. memory stays stable (even though GC.stat shows 100,000,000 freed objects), but if I disable GC just before, memory balloons
sinaef has joined #ruby
<ruby-lang813> Hm
<Travis-42> is the reason because GC is running before the heap size increases, freeing and reusing old slots?

<apeiros> Travis-42: a) #rubyonrails and b) I think you're talking about old rails versions where .all was what .to_a is today, i.e. reads all into memory upfront.
devoldmx has quit [Ping timeout: 256 seconds]
<Travis-42> apeiros: I’m really not trying to ask about rails, I’m trying to understand ruby memory allocation
<Travis-42> it was just an example
<apeiros> Travis-42: then you should use an example you fully understand
ddarkpassenger has joined #ruby
<apeiros> also "better" does not exist. "in context X better" exists.
<Travis-42> User.all.each still works in rails 4.2.3, but I’m sorry if my example was a little outdated, I’m just trying to understand why allocating 1000 item arrays 100 times doesn’t balloon memory the same way that a single 100,000 item array would
<apeiros> and wrt ruby gc, one aspect of the context is the specific ruby version, since GC has changed quite a bit from 1.9 to 2.0 to 2.1 to 2.2
<Travis-42> Ruby 2.2 Is really where I’m looking at
catoblepa has joined #ruby
<apeiros> Travis-42: that's what I mean by "fully understand". yes, it still works. but no, it doesn't work the same anymore.
<apeiros> rails 3.x .all returns an array. rails 4.x .all returns a relation.
<Travis-42> 100_000_000.times { foo = “a string” } doesn’t balloon memory (unless GC.disable is called), even though it allocates 100,000,000 objects
<apeiros> *massively* different beast.
timonv has quit [Ping timeout: 250 seconds]
leat1 has joined #ruby
<apeiros> that'd most likely be because `foo` goes out of scope on every iteration and can be GC'd

<apeiros> and ruby 2.2 has a generational gc too, and foo almost certainly remains in the young generation which gets GC'd more aggressively.
pdoherty has quit [Quit: Leaving]
<Travis-42> right, so the reason the creating 1000 item arrays 100 times doesn’t balloon memory is because GC is running during the process — the slots in the ruby heap can’t be reused until GC in some form runs
voltalio has quit [Quit: My Mac has gone to sleep. ZZZzzz…]
<Travis-42> that makes a lot of sense, thank you apeiros. I wasn’t sure that I understood the basic idea
<apeiros> hu?
<apeiros> 100_000_000.times { foo = “a string” } does *not* create *any* array at all

<prefixed> i have an object with some fields. i want to ignore one when iterating over the fields
<prefixed> this is not a hard concept
<toretore> ruby objects don't have fields

<roolo> Is there way in Jekyll to define dependencies?
<roolo> Example: I change one post and I want also tags page to be regenerated
<havenwood> BraddPitt: Happy to discuss in #ruby-offtopic or #ruby-community.
<litn> hi guys, is there a better or more barebones framework than ruby on rails?
<shevy> lol
<baweaver> litn: Sinatra
DCameronMauch has joined #ruby
<BraddPitt> well havenwood I would like to but it seems people just avoid discussion there
<shevy> litn sinatra and padrino perhaps
christiandsg has quit [Ping timeout: 265 seconds]
<BraddPitt> litn try python and flask
<havenwood> litn: Roda
<baweaver> Padrino is Sinatra with some extra features
<shevy> and cute little beavers as icons \o/
<havenwood> litn: Roda is lovely! By the maintainer of Sequel.
<litn> alright, I'll check out Roda and Sinatra
<baweaver> does it really?
<litn> thanks guys
<havenwood> litn: Sinatra has been around a lot longer. Roda is a project made by a Sinatra/Rails user and it's totally my cup of tea.
banister has left #ruby [#ruby]
<havenwood> litn: Another one you might look at is Lotus.
<litn> roda's website is pretty bad
<havenwood> litn: With Roda you start with just a routing tree and add plugins for additional features as you need them.

<baweaver> then again I would also not judge a framework by their lack of a designer.
<litn> this is a deeper issue than not having a designer
<litn> please look at this

<havenwood> It's aesthetically lovely.
<shevy> though, cgi with some modifications like cgi-exception and such
<havenwood> Minimalist. I enjoy the code.

<litn> do you guys really use cgi
<shevy> I really do!
<litn> that's bad
<sstangl> cgi is fine
<litn> it's fine for small projects that are sub 100 users
<sstangl> it scales up to a few ten thousand users no problem
<litn> maybe
<BraddPitt> lmao don't you use cgi too litn
<havenwood> litn: Very black and white? Bad and good?
<litn> no
<sstangl> no cgi is good these days
<BraddPitt> I remember us talking about it a while ago
<litn> cgi is good for small projects
<havenwood> litn: cgi isn't commonly used with Ruby but you see it
<shevy> well, when you have a class in ruby, then you just serve it or the string, so you could do so via a .cgi file or rack or anything else really
<BraddPitt> or FCGI
<baweaver> I like CGI too. Easier to hack.

<yashinbasement> so my question what does srand 1 do
<baweaver> who knows, strange things happen.
WillAmes has joined #ruby
<baweaver> Mon_Ouie: It sets the seed of the Random number generator. After a call to srand(1), subsequent calls to rand will consistently produce the same results.

<radens> Hey, where can I speak to the ruby developers?
Limix has joined #ruby
<radens> I found something odd in ripper that I think is a bug.
* baweaver looks at channel name
<baweaver> Most of the time there's a ruby bug tracker if it's in source
<baweaver> just a sec.
tokik has joined #ruby
<radens> baweaver: #python is not where you go if you want to ask guido about the python parser.
<baweaver> yes, but #elixir-lang is where you can ask Jose about elixir :)
<baweaver> depends on the channel / group honestly.
dimasg has quit [Ping timeout: 244 seconds]
<baweaver> there it is
<baweaver> as far as I know, Ox0dea and tenderlove tend to be more frequent on the core issues
