[15:23:58] Iambchop: ruby mjit generates and compiles c for parts of the program at runtime: https://medium.com/@k0kubun/the-method-jit-compiler-for-ruby-2-6-388ee0989c13
[15:24:52] Iambchop: to distribute a program look at things like traveling ruby or ruby packer
[15:58:49] Iambchop: headius: I've never used the newer JRuby AOT stuff, but custom jruby-complete jars (and wars) to distribute programs (internally) improved my life; thanks for that :-)
[16:02:17] Iambchop: I've used mruby to compile (simple) nagios check scripts, that's worked well
[18:45:06] Iambchop: jwr: failed to reproduce for me here https://dpaste.de/add5
[19:09:03] Iambchop: your ./bin/bundle is from bundler binstub? added rake to my Gemfile and used bundle binstub: https://dpaste.de/nqyV

[17:56:04] Iambchop: FrostCandy: "it doesnt work" means what? it would be helpful if you could provide the code, expected output, actual output, and any error messages: https://dpaste.de
[18:06:18] Iambchop: FrostCandy: https://github.com/rubocop-hq/ruby-style-guide/blob/master/README.md#syntax " Use :: only to reference constants...Do not use :: for regular method invocation"
[18:14:03] Iambchop: What gem and what version of ruby/rails?
[18:22:57] Iambchop: Okay, some confusion on terminology: "OpenStates::Bill.where(state: 'tx', q: 'taxi')" OpenStates is a module, OpenStates::Bill is a class
[18:24:29] Iambchop: depending where in the rails stack you are calling this from "parameters" is a defined method, that could be where you got tripped up there

[14:10:42] Iambchop: nebg: how is your ruby installed? vendor package, rvm, self compiled. etc?
[14:29:32] Iambchop: nebg: "rvm @global do gem install bundler"?
[23:02:48] Iambchop: hays: RFC2616 said that (most) redirects should keep the same request method, most browsers ignored that and switch to GET https://trac.ietf.org/trac/httpbis/ticket/160

[22:37:10] Iambchop: oh, leftylink beat me to it :-)
[22:40:51] Iambchop: depending on your actual end goal: 3.times is probably better than the range :-), map is probably even better

[01:44:59] Iambchop: isene: I finally got around to launching an 18.10 VM and reproduced with the stock ruby package; my niece needs to work on a project, so I still won't be able to dig into it yet.
[04:52:02] Iambchop: tested gmail imap @sock.hostname in my VM successfully; tried a few times to pass an openssl context callback through the IMAP.new call, but failed (something like "Net::IMAP.new('imap.gmail.com', port: 993, ssl: {servername_cb: lambda{|sock, name| sock.hostname=name}})"); way past bed time, goodnight :-)
[13:03:21] Iambchop: yeah; I think I tried everything in the docs that was named _cb or _callback; I failed at all :)
[15:48:39] Iambchop: aha! "Cannot confirm that this affects bionic. This may be due to openssl 1.1.0 (in bionic) sending a default SNI when none is provided, whereas 1.1.1 (in cosmic) sends nothing." https://bugs.launchpad.net/ubuntu/+source/fetchmail/+bug/1798786/comments/9
[20:47:19] Iambchop: "SNI has been made mandatory to implement in TLS 1.3 but not mandatory to use. Some sites want to encourage the use of SNI and configure a default certificate that fails WebPKI authentication when the client supports TLS 1.3. This is under the assumption that if a hostname is not sent, then it means that the client does not verify the server certificate (unauthenticated opportunistic TLS). For implementation that actually don't
[20:47:20] Iambchop: send the SNI extension, but do verify the server certificate this can cause connection failures." https://wiki.openssl.org/index.php/TLS1.3#Server_Name_Indication
[20:48:50] Iambchop: isene: Net::IMAP.new "imap.gmail.com", port: 993, ssl: {ssl_version: :TLSv1_2, verify_hostname: false}}
[20:49:25] Iambchop: ^ fallback to 1.2 seems to work here

2018-12-21

[10:50:56] Iambchop: isene: are you using ubuntu's packaged, build your own, 3rd party package? you used imap.gmail.com:993 on your s_client test? the line you said it's failing on "imap.gmail.com" isn't in the script you posted (ms[0][0] is in the script). test with just a minimal example e.g. $ ruby -r net/imap -e 'p Net::IMAP.new("imap.gmail.com", 993, ssl: true)'
[17:12:40] Iambchop: KrzaQ: when should it return val instead of first (e.g. only if array is empty, only if first is nil, only if first is falsey)?
[17:12:49] Iambchop: &>> [([1,2].first || 3), ([nil,4].first || 5)]

[14:56:26] Iambchop: marz_d`ghostman: ^ @db in the module definition is not the same as @db in the method definitions; [Foo.instance_variable_get(:@foo), qux.instance_variable_get(:@foo)] => ["42", nil]; note the different "self" in each location

[03:49:52] Iambchop: lunorian: "Ruby blocks are little anonymous functions that can be passed into methods. Blocks are enclosed in a do / end statement or between brackets {}" https://www.rubyguides.com/2016/02/ruby-procs-and-lambdas/#Understanding_Ruby_Blocks
[03:55:19] Iambchop: e.g. "[1,2,3].each do |n| puts n; end" or "[1,2,3].each{|n| puts n}": the do/end (or {}) is an anonymous function passed into the each method
[04:07:26] Iambchop: I think that if it was "class Foo(a,b,c) do" the do keyword would be wasted and not provide any new info when parsing/reading the code that the class keyword didn't already provide. :)
[04:13:27] Iambchop: Oh, I meant "class Foo do" or "def bar(a,b,c) do" there but squished them together. :-)
[04:32:51] Iambchop: What do you mean by "is possible to use it"? It's not posdible; "class Foo do" errors out. (There is a way to create an anonymous class that does not use the class keyword, but does use the do keyword; I was leaving that out because I didn't want to complicate matters.)
[04:35:21] Iambchop: http://blog.jayfields.com/2008/02/ruby-creating-anonymous-classes.html
[04:40:58] Iambchop: If you've seen code that used "Class.new do" that was an anonymous class. The do keyword is used there because it's actually passing a block to the "new" method. But, "normal" methods just use the class keyword.
[04:42:37] Iambchop: of course that should read "normal *classes*" :-)

[00:33:16] Iambchop: maslen: custom_pg_hba_entries is a Hash, entries is an Array (of Hash), compare yours to the example: https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-config-template/gitlab.rb.template#L833 "postgresql['custom_pg_hba_entries'] = { APP1: [ { type: example, ... }, ... ], APP2: {...}, ... }"
[00:35:12] Iambchop: (crap messed up my cut-down example punctuation there, but the real example is still good :-)
[00:36:11] Iambchop: (forgot to add the [] when I rushed to add APP2)

[02:26:06] Iambchop: jayjo: helpy is a rails app, so rails docs may answer some of your questions. the db:migrate task will load all of the migration files in the directory; on subsequent runs it will skip files it has loaded before. the db:seed task runs the seeds.rb file. those are standard rails conventions. https://guides.rubyonrails.org/active_record_migrations.html

[03:46:30] Iambchop: ivanskie: you mean like a post-install script? by design gems don't support that; depending on why it needs done perhaps the installed gem could detect the need and do it automatically on first run or include instructions in a post-install message https://stackoverflow.com/questions/14395992/how-to-execute-a-script-while-gem-installation

[03:01:14] Iambchop: sioux: are you running bundle exec from the redmine directory root?
[03:13:29] Iambchop: from that link 3.4 is compatible with ruby ruby 1.9.3, 2.0.0, 2.1, 2.2, 2.3, 2.4 so your ruby should be ok
[03:14:45] Iambchop: then the bundle install should get the right version of rails
