<Spooner> lkahtz : the answer you already have does a good job.
<lkahtz> Spooner: Thanks, it takes a couple of hours of meditation :)
<Spooner> For your code, you would be better with: str.each_char.with_index.map do |s,i|
<lkahtz> right~ Spooner. That's cleaner
<lkahtz> :-)
<Spooner> Well, not really important, but avoids creating an array of chars, but rather iterates them directly. I love pointless optimisations like that :)
Gab0 has quit [Remote host closed the connection]
<Spooner> lkahtz: I'm not sure why you want to re-write permutation though. Maybe look at the C code if you are keen?
<lkahtz> Haven't check the code of each_char_with_index, but it removes the temp chars created indeed :)
<lkahtz> Just want to hone my ruby-fu... nothin' much~
<Spooner> each_char.with_index (except for each_with_index, you have to use #with_index)
<lkahtz> maybe I should read C code since it is more earth grounded
<lkahtz> cool

tompsony has quit [Quit: CyberScript - if you don't try it, you can't tell me it sucks. (www.cyberscript.org)]
<Spooner> Surely floats have infinity too?
<banisterfiend> naw it'll downgrade it anyway
<banisterfiend> Yeah
<Spooner> Actually, I should try it and see if it is a double issue. One minute.

<Spooner> banisterfiend : Oops, I was breaking infinity myself! How careless :D
jhunter has quit [Ping timeout: 246 seconds]
<banisterfiend> Spooner: how
<Spooner> It was based on how I set values in particles. Usually I do stuff to pick a value between min and max when creating a new particle, but if both were INFINITY, it broke my naive code.
<Spooner> banisterfiend So it appeared to be creating NaN from infinity, but I was thinking it was happening earlier than it was.
<banisterfiend> oh ok

jonnn has joined #ruby
<jdiez> why not?
<jdiez> I enjoy learning new languages
<banisterfiend> jdiez: i'm just curious
<jdiez> oh
<jdiez> I'm curious too :P
<jdiez> I don't know, some of the ruby stuff intrigues me
<banisterfiend> jdiez: cool, which ruby stuff?
<jdiez> like the method? and method!
<banisterfiend> hehe
<jdiez> I have no idea what that does
<banisterfiend> :P
<banisterfiend> jdiez: method? is just for predicates, so say i have an array
<banisterfiend> jdiez: to find out if the array is empty i go: array.empty?
<banisterfiend> and it returns true or false
<jdiez> so how is it different from saying "if array.empty()" ?
<banisterfiend> jdiez: it's not, it's just potentially more readable as it's clear the method returns a boolean value
<fowl> empty is a verb, so it should be clearing the array
<banisterfiend> that it's a method strictly for querying an object
<banisterfiend> exactly
<jdiez> okay, I get it, fair point
<jdiez> and the method! stuff?
<ryanf> in a language without ? you'd probably say like is_empty
Abbas| has quit [Quit: BadingaDongDongDong-TwitchVeryStrongStrongStrong]
<ryanf> because otherwise empty() could mean "empty this array"
<jdiez> also, I have seen some function calls without () around the arguments
<ryanf> so it's just a nicer way of doing the same thing
<banisterfiend> jdiez: yeah, we dont need () in ruby ;)
<jdiez> hmm
<jdiez> interdasting
<heftig> jdiez: "dangerous" variants, mostly because they modify the receiver instead of returning a copy
vvgomes has quit [Ping timeout: 272 seconds]
<heftig> e.g. Array#shuffle and Array#shuffle!
<jdiez> also, doing "def method?" is equal to doing "def method", right?
<heftig> jdiez: no, it's not
<heftig> the former creates the method named "method?", the latter the method named "method"
<banisterfiend> jdiez: just that ? and ! are valid characters to be used in a method name (if they're the last character)
<jdiez> hmm
<jdiez> okay
<jdiez> so ? and ! are just conventions?
<banisterfiend> Yeah
<heftig> yes. language-wise they have no special function
<jdiez> hmm
<jdiez> interesting
<jdiez> okay
<jdiez> also, what is an attr_reader and why do I need those?
<banisterfiend> jdiez: but really, those things are the least interesting aprt of ruby, 'blocks' are the coolest part, also executable class bodies
<heftig> attr_reader :foo, :bar is a quick way of doing def foo; @foo; end; def bar; @bar; end
<jdiez> yeah, those were the things that intrigued me the most :P what are blocks?
<banisterfiend> jdiez: a full explanation of what attr_reader is, and how it works will probably impress u
<banisterfiend> hopefully heftig will explain, i have 1 min of battery left :)
<jdiez> haha
<jdiez> I'm all ears
<jdiez> and I'm also intrigued about blocks
<heftig> blocks are closures attached to a method call
<heftig> if that means anything to you
<jdiez> hmm
<jdiez> do a local function
<jdiez> ?
<jdiez> so*
<fowl> blocks are the building experience of Happy Ruby ^^;
<heftig> >> def foo; yield 3; end; foo { |x| puts 3 }
<al2o3cr> heftig: (String) "NoMethodError: undefined method `foo' for main:Object"
<heftig> bah
<heftig> anyway
<heftig> er
<heftig> def foo; yield 3; end; foo { |x| puts x }
<heftig> this is better
banisterfiend has quit [Remote host closed the connection]
<heftig> the { |x| puts x } is a closure, taking one parameter and doing something with it
Abbas5 has joined #ruby
<heftig> it's called the block
<Spaceghostc2c> It's also a proc!
<heftig> Spaceghostc2c: not unless you make it one
<jdiez> so a { |x| puts x } block would just print a list?
<heftig> when it's run, it just does puts with the parameter
<heftig> i attach it to a call of the method "foo"
<Spaceghostc2c> heftig: No, it's always a proc.
<heftig> foo runs "yield 3" which runs the attached block with the parameter 3
bradhe has quit [Remote host closed the connection]
<jdiez> hmm
<jdiez> oh
<jdiez> the yield keyword is used very differently on python
<Spaceghostc2c> You can easily forget it is and just pass it around, but it's represented as a proc whether you like it or not.

<Spaceghostc2c> heftig: You really believe that?
jhunter has joined #ruby
<heftig> Spaceghostc2c: in the above example there is no Object representing the block
<Spaceghostc2c> heftig: def foo &blk ; puts blk.class; end
rizzy has joined #ruby
<heftig> Spaceghostc2c: that wraps it into a Proc for you to use
nari has joined #ruby
<heftig> jdiez: it's a piece of metaprogramming that creates methods for you
<Banistergalaxy> Jdiez it's a class method that builds instance methods
<Spaceghostc2c> And behinds the scene, it's still a proc, even if you aren't asking for one.
dpk has joined #ruby
<Banistergalaxy> Jdiez it works because class bodies are executable
<ryanf> my understanding was that it doesn't actually create a proc object unless you make it
<ryanf> which is why yield is faster
<heftig> indeed
<Spaceghostc2c> You know, that might be true. Let me look.
<ryanf> yes, I do know it might be true
<Banistergalaxy> Hehe

mockra has quit [Remote host closed the connection]
<Spaceghostc2c> heftig: Thank you for correcting me. I was pretty damn sure. :)
<Banistergalaxy> We can build them when we need them, we don't need special syntax
<Spaceghostc2c> ryanf: And you, for giving me the heads up on the down low.
<Spaceghostc2c> jdiez: Are you asking for a pattern?
mockra has joined #ruby
<Spaceghostc2c> I think avdi grimm had one.
<jdiez> I'm asking for a way to do function = decorator(function)
<heftig> Spaceghostc2c: method decorators, i think, not the Decorator pattern
<ryanf> oh
<Spaceghostc2c> heftig: A pattern, not the decorator pattern.
<jdiez> like I would do in python like @decorator / def function: / blabla
<ryanf> jdiez it depends a bit on the use case. you can get a reference to a method using the method method
<ryanf> or do various things with alias
<ryanf> but I guess the most relevant info is that class bodies are just normal code executing in the context of the class
<Banistergalaxy> Jdiez yeah, we can get syntax similar to that just using class methods or whatever
<ryanf> so you can do whatever you want in the form of a class method
<ryanf> (except you have to call the method after defining the method instead of before)
ringotwo has quit [Remote host closed the connection]
<ryanf> haha yeah you can do that too
<ryanf> and actually there is at least one lib that does: https://github.com/egonSchiele/contracts.ruby

<burgestrand> For the general case const_get, since it’s less dangerous.
Abbas| has quit [Read error: Connection reset by peer]
<burgestrand> However, const_get approach requries some modification to work fully with namespaces in the names, e.g. MyModue::MyClass

<banisterfiend> libryder: what dont you understand
<banisterfiend> libryder: you only included MyShinyModule into Object, so it's method will be invoked. The 'nested' modules were not included so their methods cannot be invoked
<libryder> MyShinyModule::FirstModule.my_method worked, but it called the method from its parent class
<banisterfiend> its*
mohits has joined #ruby
<banisterfiend> libryder: yes, because FirstModule#my_method is an instance method, it can't be invoked on FirstModule
<libryder> if i do include FirstModule, then FirstModule.my_method, it works as expected
<samuelkadolph> libryder: You included MyShinyModule
<samuelkadolph> Not MyShinyModule::FirstModule
<banisterfiend> libryder: you need to read about difference between instance methods and class methods
Godslastering has quit [Read error: Connection reset by peer]
<libryder> banisterfiend: i understand that
<banisterfiend> in order to invoked FirstModule#my_module on FirstModule you have to (in this case) include FirstModule into Object, which you didnt do
<banisterfiend> my_method
mascool has quit [Ping timeout: 240 seconds]
<samuelkadolph> libryder: You included the module that returns "the parent method", what don't you understand?
<libryder> samuelkadolph: by that logic, could i do MyShinyModlue::DoesNotExist.my_method and expect it to work?
<samuelkadolph> If DoesNotExist was a class or module, yes
<libryder> but before including it, it would call its parent method?
<samuelkadolph> You've included a module into Object, it will be available to any class/module as class methods

<macer1> where are padding functions? I have no idea about that
Bofu has joined #ruby
<bnagy> macer1: you didn't give it a keysize
<vandemar> macer1: oh, at least on my system, it's generating some trivial size rsa key by default. try saving the rsa key to a var then printing it before calling var.public_encrypt
<bnagy> (require 'openssl'); OpenSSL::PKey::RSA.new(1024).public_encrypt 'a' try that
<macer1> no segfautl
<macer1> good progress
<vandemar> macer1: if I manually do a 128 bit key, I get a different error about the key being not long enough to encrypt the data. Only at 256 and above does public_encrypt actually succeed

<bnagy> it should pad it for you

<macer1> "On receipt of a 0xFD from the server, the client will generate a 16-byte shared secret, to be used with the AES/CFB8 stream cipher. It then encrypts it with the server's public key (PKCS#1 padded), and sends it to the server along the token recieved in 0xFD encrypted with server's public key with a 0xFC."
<macer1> this is what I am doing...I think
fourlastor has joined #ruby
<bnagy> public_encrypt is correct, and it will use PKCS1 by default
<vandemar> I think ruby is doing something wrong when RSA.new is called without a keysize.

<fourlastor> let's say i want to implement a "clickable" behaviour, as in many different objects have 2 methods: click and clicked, the first takes a block of code as a parameter and saves it for later execution, the seconds fires it. would be better to use a mixin or inheritance? i'd say mixin but since i have to store the block somewhere it sounds more as a super class
<fourlastor> many different classes*
<macer1> the problem with padding is somewhere there... public_key.public_encrypt(@key).unpack("C*")
<ij> Why can't I define Foo#bar<<?

<macer1> bnagy: to bytes
vectorshelve has quit [Ping timeout: 245 seconds]
<bnagy> it already is bytes :) that unpack will give you an array of ints
<macer1> no, it's a byte string
<bnagy> I don't know what you think a 'byte string' is
<workmad3> ij: some_foo.bar << "whatever" get's parsed as 'some_foo.bar().<<("whatever")', not as 'some_foo.bar<<("whatever")'
<macer1> it is "\x00\x11" etc.
<macer1> In protocol I need to send this as array of ints :)
<bnagy> yeah that's just a string :)

<macer1> bytes*
dhruvasagar has quit [Ping timeout: 246 seconds]
<workmad3> ij: which is in contrast to 'some_foo.bar = "whatever"', which get's interpreted as 'some_foo.bar=("whatever")'
<ij> workmad3, Myeah, I somewhy thought I can make it work like I want it. Ha.
<workmad3> ij: well, it just means you need to override the << method on the object returned by bar, not some non-existant bar<< method ;)
<bnagy> macer1: how can you send a ruby array full of ints in a packet?
<shevy> ij ahhh now I understand
dhruvasagar has joined #ruby
<shevy> you meant a "bar<<" method
<macer1> bnagy: bindata
<ij> workmad3, Unfortunately that object's array, which I won't define methods on. :]
<bnagy> let me guess... you're going to pack them. And end up with exactly the same as before you started :)
<shevy> wasn't bindata written by bnagy?
<macer1> I can delete the unpack there, it is converted in other class anyway
<bnagy> no I have my own version
<shevy> or what was the name again... hmm
<workmad3> ij: wrap it in a proxy that provides your method override when you return it from bar
<shevy> ah yes
<bnagy> binstruct
<workmad3> ij: or extend the specific instance with a module that provides your specialised method
<bnagy> macer1: a ruby string is just a collection of raw bytes
<workmad3> ij: there are a lot of ways within ruby that are great for specialising specific instances of a class, without monkey-patching the entirety of a core class :)

<ij> workmad3, How do I do the proxying? Is there some standard way to do it?
ZachBeta has joined #ruby
<bnagy> macer1: so basically that string should be 128 bytes, and appear in the final packet
<ij> Object#class is douchebaggery. I can call it only through obj.class, but not class.
<workmad3> ij: with 1.9, a fairly standard way would be to subclass BasicObject, give it an initializer that takes the object to proxy to, a simple method_missing that forwards on all methods, and the overridden methods you want

<Iszak> not quite like that.
<Iszak> All the data is in the database, maybe PostgreSQL has something like this.
<workmad3> Iszak: well, to go beyond that, you are going to need to describe how it should be parameterised... how close a match do you want to allow?
<workmad3> Iszak: is another fuzzy match algorithm maybe more appropriate?
<Iszak> workmad3: parameterised, the regex?
<workmad3> Iszak: as I'm guessing that's your goal... to generate a regex that will determine if string X is somehow 'close' to strings A,B,C
<workmad3> Iszak: the closeness needs to be parameterised...
r1chelt has quit [Remote host closed the connection]
<Iszak> it must match the length (variable) and the common substring, the other characters will definitively be alpha numerical.
<Iszak> so something like [A-Z0-9
<workmad3> Iszak: so you can describe what is close and what isn't (e.g. more than 10% difference, less than 5 characters difference, no more than 2 adjacent characters different...)

future_chimp has joined #ruby
<Iszak> well, I can't really put a percentage on it because it can be more if it's longer.
Rochefort has joined #ruby
<workmad3> Iszak: that sounds very like a percentage then...
<Iszak> Not necessarily.
<Iszak> it could be the same length, but different percentage depending on the common substring.
<workmad3> Iszak: ok... it actually sounds like you don't know exactly what you need I'm afraid
<workmad3> Iszak: which makes coming up with a concrete algorithm pretty much impossible
<workmad3> Iszak: I'd personally suggest doing a few worked examples on paper, going from source string(s) to regex
<workmad3> Iszak: and then try to extract some sort of pattern from that
<Iszak> I know exactly the regular expression I'm looking for, but like I said, it all depends.
<bnagy> I still think regexp probably doesn't belong here
<bnagy> but without a concrete problem statement it's all handwaving
<workmad3> Iszak: if 'it all depends' is code for 'there isn't a pattern', then what you have is a set of special cases that you'll need to code explicitly
Lachryma` has joined #ruby
<workmad3> Iszak: if that set of special cases is infinite in size... sucks to be you, you'll be coding them for a long time ;)
<workmad3> Iszak: if there is a pattern though... you need to work out what it is
<Iszak> well it's really calculating two different things, first is the common substring problem, then it's calculating the length range (easy).

bullicon has quit [Quit: Computer has gone to sleep.]

<Iszak> Here's the full problem, so basically the user inputs a string, we then make multiple requires to multiple APIs, they will return whether it's a match or not. Now instead of having to call every API, it would be nice to match the user string first against a common pattern which each API has. This common pattern can change at any time so I can't hard code it unfortunately.

<dr_bob> Iszak: maybe a two step approach works: each API publishes a pattern, you collect these in a Hash which uses the pattern as key and an Array of APIs as value. Of course your APIs would need to write the patterns in a uniform way so enough of them have the same pattern. Then you only match against keys in the Hash and for a match you match against all APIs (or until you find a match).

<Muz> jrajav: had an idea for long (and terminated) output, why not post it to pastie/pastebin/whatever and have the bot return a link to that?

<jrajav> That's an okay idea
<jrajav> Might be a little unwieldy
<jrajav> I'm more inclined to avoid automatically pastebinning anything as long as there's not an actual problem with sending tons of output through IRC PM

<workmad3> jrajav: there is a limit on message length
<jrajav> workmad3: Do you know what it is?

<nateberkopec> is it kosher for a "?" method to return a value that isn't 'true' or 'false'? like if Order.subscribed? returns nil?
<nateberkopec> speaking idiomatically
cantonic has joined #ruby
<apeiros_> it's uncommon
<Sou|cutter> nateberkopec: idiomatically, it only needs to be "truthy"
<apeiros_> and I'd not do it
<apeiros_> but there are examples of non true/false returns in core/stdlib
<apeiros_> (File.size? iirc being one)
<nateberkopec> k, that's what I thought.
<dr_bob> Sou|cutter: a primitive size monitoring would count instances via ObjectSpace. I once did a bit of coding around that with delta output which helped finding memory leaks.

<infinitiguy> How would I pull out say the InstanceIds?
<infinitiguy> do I need to go down the chain to be able to find it?
<davidcelis> that looks like XML; maybe you should be using an XML parser like Nokogiri
<Muz> It's not XML.
<Muz> It's JSON. It looks like a JSON representation of data that was originally stored in XML for some reason.
<davidcelis> Looks like XML converted to a hash to me
<infinitiguy> it might be - I'm using a rubygem for amazon ec2. I think it may use nokogiri under the covers

verto is now known as verto|off
<apeiros_> davidcelis: it probably *was* but it clearly is no longer
<apeiros_> infinitiguy: mylb.class returns what?
<infinitiguy> I was very excited when I was able to actually get the data - now I just don't know what to do with it :(
<infinitiguy> lets see..
<apeiros_> err, rather, mylb.Listeners.class
chimkan has quit [Quit: chimkan]
<infinitiguy> both have no results
<infinitiguy> puts "Classing LB"
<infinitiguy> mylb.class

<infinitiguy> mylb.Listeners.class
<davidcelis> no, puts the .class lines
<davidcelis> we need to see what those output
cantonic has quit [Quit: cantonic]
<apeiros_> but the answer is probably mylb.Listeners["DescribeLoadBalancersResult"]["LoadBalancerDescriptions"]["member"].flat_map { |instance| instance["member"].map { |member| member["InstanceId"] } }
<apeiros_> depends a bit on the actual data. but maybe you get the idea.
<infinitiguy> ah - mylb.class = hash
<infinitiguy> mylb.listeners.class = NilClass
<apeiros_> yepp. so it's *not* xml, it's *not* json. it's plain old ruby. the conversion has already happened.
<davidcelis> most unfortunate
<apeiros_> (and yes, it probably was xml once, xmlns tells us as much)
<infinitiguy> so all the output I see is a big hash?
<davidcelis> yep, just a big ol' Hash
<infinitiguy> I see - In ruby how can you chop up a Hash? (if that's even the right way to phrase it)
apok has quit [Quit: apok]
<infinitiguy> In this case - I don't care about most of it - only a couple values
<apeiros_> infinitiguy: use `ri Hash` in your console (bash…)
<apeiros_> and I gave you an approach above
<RubyPanther> with #delete
<davidcelis> you probably don't want to "chop it up", just pull out what you want like apeiros_ showed you
<infinitiguy> what is ri? I don't have that command
<apeiros_> infinitiguy: look at Hash#[], #values_at, #each, #each_key and #each_value
<apeiros_> infinitiguy: ri is the documentation tool. your ruby installation is rather incomplete if you don't have it.
<RubyPanther> ri is a long wait for a weak search
<apeiros_> you can use rdoc.info or ruby-doc.org instead
<apeiros_> RubyPanther: BS
<infinitiguy> hrm - I have ruby-rdoc installed (rpm -qa)
<infinitiguy> assuming it's not included with that?
<apeiros_> maybe if you're still on a 486…
<apeiros_> ugh, rpm

<apeiros_> yes, defenstration seems adequate.
<Muz> How is it this channel has edged closer towards going full-retard in little under 15 minutes.
<Muz> It was all so nice and sensical before!
<Synthead> apeiros_: I'm looking to have it "count" the hash keys. So { 'a' => 1, 'b' => 2, 'c' => 3 }.each_with_key { |key, value, i| puts "\##{i}: #{key}: #{value}" }, if it existed
<apeiros_> Muz: you went silent. speak up and make it non-retard again.
<whoev> throw a "map" in there while you're at it
<whoev> actually, alias "map" to ꝎꝏꝎꝏ
<Muz> apeiros_: the cycling on the McLympics is far too fascinating right now.
<apeiros_> Synthead: again, there is no Array#each_with_key. I don't know what you're fantasizing there…
<apeiros_> Synthead: you can do each_with_index, but that makes so little sense with a hash.
<Synthead> apeiros_: ok, thanks
<whoev> but there is each_with_index, no?
<apeiros_> ^
<Hanmac> Synthead: hash.each_with_index{|(k,v),i| }
<Hanmac> the () around the values is !important!
<Synthead> yeah! that works! thanks!
<apeiros_> ¡muy importante!

<fennec> so according to http://www.ruby-doc.org/core-1.9.3/IO.html#method-c-popen, "If a block is given, Ruby will run the command as a child connected to Ruby with a pipe. Ruby’s end of the pipe will be passed as a parameter to the block. At the end of block, Ruby close the pipe and sets $?."
<fennec> buuuuut I've been seeing $? of nil right after a popen block.

<cassianoleal> so, I'm using VCR to record HTTP calls with basic_auth and then using a_request matcher from webmock to validate the requests
<cassianoleal> I'm having a problem with that because apparently VCR records the basic_auth credentials in the URL (http://user:pass@some-url) instead of in the headers

<shevy> asteve not sure there is an easy way

elhu has joined #ruby
<shevy> you can however use FileUtils.mv() without having to cd into a directory
<shevy> if your file operations also includes deleting a directory, this can be a problem when you remove the base directory of where ruby was started
chichou has quit [Ping timeout: 250 seconds]
<shevy> for instance
<shevy> Dir.chdir "/Depot/jjj/foo/"; FileUtils.rm_rf "/Depot/jjj/foo/"

<arturaz> ruby probably has some libs that python does not

<arturaz> atrika, I'd advise you against using an intepreted language in game development
<arturaz> Take Java/Scala/Mono instead
jjbohn is now known as jjbohn|lunch
<atrika> isnt java interpreted ?
whitedawg1 has joined #ruby
<arturaz> not really, its JIT compiled
<atrika> and isn't python also compiled ?
<arturaz> python is sort of compiled into intermediary representation
<arturaz> the problem is that java virtual machine is far superior and faster than one in python
<Mon_Ouie> Called bytecode. But that's like any recent programming language.
paolooo has joined #ruby
<Mon_Ouie> Some like Java also generate native code at runtime; There are implementations of booth Python and Ruby that use the same technique (respectively Pypy and Rubinius)
Gab0 has quit [Remote host closed the connection]
<Spooner> arturaz : I am not sure that interpreted matters. Certainly, the CRuby garbage collection is not game-friendly, but there is no problem at all with writing games in it other than that.
Gab0 has joined #ruby
<arturaz> Spooner, well, as long as you don't hit cpu bottleneck :)
whitedawg has quit [Ping timeout: 244 seconds]
<arturaz> or need threads for that matter
ken_barber has joined #ruby
<Spooner> Yes, but that is an issue of requirements, not a real limit. If you want to write a AAA 3D game, you have to do it in C++ with probably some dropping into assembler for your bottlenecks. If you want to make a simple 2D game, then there isn't an issue with Ruby.

fennec has quit [Quit: Leaving]
<Spooner> I don't know. You could drop to C where it mattered. After all, most Ruby is just calling C stuff (like Gosu or Chipmunk or whatever else). Just depends how much of your engine you could write in C (or rather was already written/wrapped) and how much in Ruby.
lurch007 has joined #ruby
<arturaz> Spooner, what's exactly the point of writing ruby then? :) And why not take, erm, lets say, scala?
adambeynon has quit [Quit: ["Textual IRC Client: www.textualapp.com"]]
<Spooner> You write in C++ without using libraries?
<Spooner> So why is there a difference between using C/C++ libraries from Ruby?
<codora> arturaz: would you write scale as a replacement for C?
<codora> *scala
<codora> i'm confused.
greenysan has joined #ruby
<arturaz> Spooner, I write Ruby using Ruby libraries. I don't write Ruby and then write C libraries myself.
<arturaz> codora, scala is statically typed and runs on jvm. Pretty fast.
<codora> jvm? so a java technology?
<Spooner> Sorry, I didn't mean writing your own C libraries (though I did mention that, it was not the point I was trying to make).
<codora> interesting.

<Hanmac> codora did you heard about wxwidgets or CEGUI or OGRE? all of them could be ported to ruby
<codora> Spooner: you know what would be cool? a full ruby desktop, with C for the low level stuff, like kernel and hardware acceleration, but otherwise pure ruby for all application and gui layer stuff.
<codora> Hanmac: i have.
<codora> wxruby exists.
<codora> cegui and ogre i have only heard about
<codora> googling.
davidcelis has joined #ruby
<Hanmac> wxruby is rubbish
<Spooner> arturaz : What I was meaning is that a significant number of Ruby libraries, not just games, are written in C (or are wrappers around C/C++ code). Sometimes people seem to get into the idea that using C to do the work for you isn't the Ruby way.
<arturaz> codora, there's still one big problem. Duck typing is slow :)
<arturaz> especially in ruby way
<arturaz> a + b needs a lot more operations than it would on java/scala
<codora> arturaz: that may be, but hardware is getting faster and faster, and the need to babysit the metal is less and less the more cores and more hardware acceleration we throw in there.
dv310p3r has quit [Quit: Leaving]
<codora> just how bad is duck typing? why is scala/java so much better to code in?
<arturaz> codora, yeah, thats all nice and everything, but I've cut parsing time in one app from 3 days into 1 hour by rewriting the code from jruby into scala.
<codora> wait, isnt java nonfree?
<arturaz> codora, check out openjdk :)
<arturaz> and duck typing, well...
<arturaz> a + b. What is a? What is b? What + in this context means?
<bperry> you could use C# and mono :)
<codora> i was told that the vast majority of tools in java are not covered in icedtea and openjdk. i was also told that java7 does not exist in open source.
<codora> bperry: yes, because C# and mono is so great :P
<arturaz> codora, openjdk7 and oracle jvm 7 is basically the same thing :)
<bperry> totally is
<Spooner> arturaz : But if you had 3 days with nothing better to do, then that optimisation was pointless. Same if you want a 2D game with a dozen sprites moving around. Why write that in C (6000fps) when you can do it in Ruby (60fps). Human eye can't tell the difference.
<arturaz> just with different branding
<arturaz> Spooner, I do not object :)
TomRone has joined #ruby
<Spooner> In fact, the great thing about coding in faster languages is that they allow you to be crap and get away with it :D In Ruby, you have to know what you are doing to get a workable FPS :P
<arturaz> Although I find I can write scala code as fast as ruby.

<Hanmac> arturaz & Spooner: thats why i write bindings ... the power of C combined with the flexable of Ruby

<codora> it means i dont have to write any damned C code.

Ethan has quit [Ping timeout: 240 seconds]
<Spooner> Still mark and sweep though, I hear, so not very game friendly, regardless of pre-compilation to bytecode. Oh well.
<codora> Spooner: it would be a massive performance gain to precompile ruby to *.rbc assembly after running ruby code once. subsequent executions would be a lot faster without having to write C.
<codora> what's mark and sweep?
khakimov has joined #ruby

<Mon_Ouie> codora: Notice there are tons of variants of mark and sweep algorithms
<eam> headius: no way, 1.9 isn't a default system ruby in nearly any distro
<codora> Mon_Ouie: i know nothing about garbage collection.
apok_ has joined #ruby
<headius> the limitation is not as much getting a new GC in but making it compatible with MRI's over-invasive C API
<arturaz> codora, jruby can switch gc's (due to jvm)
<jan0232> does anybody know a library that can fetch websites? i mean entirely…all needed images, stylesheets, referenced resources within stylesheets etc.?
<codora> arturaz: yeah, but if you are using jruby, why not just write scala? like you want?

<codora> having to declare every variable.
<headius> rubinius definitely brings a better GC to the table, but it's still nowhere near the JVM and arguably still pretty immature
<codora> headius: maybe rubinious or a similar alternative vm would make it better?
<arturaz> codora, scala is rather a different beast :)
<eam> codora: static typing has nothing to do with variable declaration

<infinitiguy> if all that was available were machete's - it would be tougher to massacre a bunch of people

<eam> infinitiguy: not true
<eam> rampage killers with the greatest murders have not used guns
<eam> they used fire, and large buildings
<infinitiguy> tougher - both for logistical reasons (close combat) and for mental reasons - hacking someone to bits is harder on the brain than pulling a trigger from far away

<Spooner> Er, we didn't "ban guns". All we did was ban handguns, which we never had a ingrained belief in owning,which is a bit different. The Issue is that if we hadn't would the crime be more or less than now. If more, then it was good. If the same, then no problem with removing guns that had no effect other than being a possibility of accident. If we are worse off now, _because we banned handguns_, then I'd like to hear proof.
