[18:16:45] dorei: DarkElement: if this doesnt work for the url you want, then maybe u need other lib to open the url, use wireshark to verify what's actually being send/received on the network
[18:17:08] dorei: there are some shitty sites that endup in an endless loop unless you get their cookies
[18:17:39] dorei: doc is your nokogiri document
[18:18:02] dorei: ready for your xpath queries
[18:19:23] dorei: DarkElement: no idea, give it a try
[18:20:21] dorei: DarkElement: from open-uri documentation: The environment variables such as http_proxy, https_proxy and ftp_proxy are in effect by default.
[18:20:27] dorei: http://ruby-doc.org/stdlib-2.3.0/libdoc/open-uri/rdoc/OpenURI.html
[18:23:31] dorei: DarkElement: try setting you proxy in enviroment variable
[18:24:34] dorei: DarkElement: if you use bash it's something like: export HTTP_PROXY="http://my.proxy.com/"

[14:43:15] dorei: looks more like a cryptogram, than a encoding issue xD
[14:43:52] dorei: maybe the numbers have the wrong endianess
[14:44:12] dorei: or maybe they're ebcdic
[14:44:32] dorei: norc_: can you paste that string somewhere in the web?

[01:44:38] dorei: [1,2,3].join(':') gives "1:2:3", if I wanted to get ":1:2:3" is there a better way than this? ([':']*3).zip([1, 2, 3]).join

[22:58:26] dorei: when doing "case str ... when regex", is $1, $2, etc the only way to access capture groups from within the when regex block?
[23:11:31] dorei: $LAST_MATCH_INFO[1] ? :O
[23:12:26] dorei: i think i'll stick with $1 :)

[00:14:37] dorei: if it cant has infinite loops, it aint a program :p
[00:16:50] dorei: shevy: no infinite loops => halt problem is decidable => no turing machine :p
[00:46:18] dorei: is there some ruby stdlib/core method for 2s complement ?
[00:46:27] dorei: >> ->x { (255 - x + 1) .to_s(16) }.(12)
[00:46:40] dorei: something like that in a less cryptic way
[00:48:30] dorei: shevy: signed int as two's complement for 8bit cpu :p
[00:48:45] dorei: -12 is 0xF4
[00:49:27] dorei: oh, xor :D
[00:49:52] dorei: if it works
[00:49:56] dorei: it works :)
[00:50:10] dorei: isnt % a xor? no?
[00:50:31] dorei: so, using modulus you can get 2s complement
[00:50:34] dorei: interesting

[18:55:05] dorei: hello, is there anything at ruby core/stdlib to help me deal with endianness?
[18:57:53] dorei: Ox0dea: i was hopping to avoid them
[19:15:16] dorei: Ox0dea: i've found a way without pack/unpack :)
[19:15:33] dorei: >> ->val{ ((val << 8) | ((val >> 8) & 0x00FF)).to_s(16)[2..-1] }.(0x3172)
[19:26:49] dorei: >> ["3172"].pack('H*').unpack('n*').pack('v*').unpack('H*')
[19:40:39] dorei: Ox0dea: what do you mean?
[20:40:56] dorei: _Tariq: https://github.com/landondyer/kasm/blob/master/LICENSE
[22:20:02] dorei: DeezCodez: i think the answer is domain specific, try project euler if you're math inclined
[22:47:43] dorei: shevy: somewhere in rails

[19:45:52] dorei: what's the difference between utc and gmt? is gmt just utc + daylight time saving or are there other differences?
[19:46:50] dorei: i think utc has no daylight time saving, while gmt has, aint sure though
[19:47:50] dorei: oh, it's more weird

[23:40:53] dorei: let's say i have an array like ['a', 41, 5, 'b', 41, 'zz', 'd'] , is there a way to split it at 41 so as to have an array like [['a'], [41], [5, 'b'], [41], ['zz', 'd']] ?

[15:09:03] dorei: i want to produce unique filenames for urls, i've used Base64::encode64(url) but the output isnt that suitable for filename
[15:18:33] dorei: wouldnt it be an overkill to use a cryptohash?
[15:29:01] dorei: in my specific case i only want to have url => filename, not both ways
[15:42:49] dorei: maybe base64::encode64 and then removing that illegal character at the end would be faster
[15:48:30] dorei: Base64::strict_encode64 instead of Base64::encode64 did the trick :)

[18:32:12] dorei: is there some standard way to document that in order to include the described module, the class that includes it should implement some method (like to include Enumerable, the class should implement #each) ?
[18:43:19] dorei: Ox0dea: i'm checking the enumerable documentation, it's just at the top
[18:43:37] dorei: btw, should I avoid using ivars at my mixins?
[18:45:52] dorei: is there other way to keep state?
[18:46:33] dorei: and if i choose to use ivars, should i become really paranoid to avoid name collissions or should I just mention it at documentation and then forget about it?
[18:58:18] dorei: i avoid thikning about that
