Binary Lottery code — how he wrote the app.<\/p>\n
Mhong – Event Machine. require ‘eventmachine’ module. `EM.run { block }` takes
\nover your ruby, and nothing after that block will be run.<\/p>\n
There’s EM::PeriodicTimer and single-fire timers: `EM.add_timer(2) { block }`
\nTo use EM in your web-app, `require ‘thin’` or spin up a new thread and use
\n`EM.run`. `EM.HttpRequest.new … EM.system () … { if status.exitstatus == 0
\n… end }`. Message queues, etc. Looks cool.<\/p>\n
Dana Gray – regular expressions. “it’s been two days since my last regular
\nexpression”. She went over the basics of regular expression string matches. How
\nto match word chars, positional anchors, capturing and non-capturing
\nparenthesis, grouping, character classes. Don’t fear regex, embrace regex.<\/p>\n
Jake Cahoon from the Utah Valley Ruby Users Group. He used a slightly
\nmonkey-patched ‘feedzirra’ module to pull tweets using Ruby code. Finshed
\nwriting the code at 2 A.M. this morning. Now it pulls tweets and puts them into
\nIRC. His code is on http:\/\/pastie.org<\/p>\n
MerbCamp videos from last year are online. How to do Rack testing. with require
\n‘rackbox\/spec’. He wrote three apps that echo text in three different
\nframeworks (sinatra, merb, rails), and showed the tests running against each.
\nAll in five minutes.<\/p>\n
Sockets and Ruby.
\n`require ‘socket’; client = TCPSocket.net(”, 6789); client.write(“Hello!”);`
\n…
\n`server = TCPServer.new(‘127.0.0.1’, 6789); client = server.accept; client.recv(500);`<\/p>\n
MongoDB – a document oriented data store. Supports native Ruby objects. Has
\nfull index support. Uses memory mapped files for speed. Has a file storage API.
\nWill support sharding soon. Best use cases: Most web apps, caching (memcachedb
\n+ indexes), when you need high scaleability. Worst case use cases:
\nTransactional systems, data warehouses. Why should you use it? Fast! No
\nmigrations, ever. Replaces memcached & tokyo. Has great Ruby support, and it’s
\nnot mySQL. http:\/\/mongodb.org<\/p>\n
It’s easy to contribute RSpecs to Rubiniess. One presenter showed how.<\/p>\n
Brian Marick: How to learn from the screw-ups of the past. He’s been involved
\nin three movements in computer programming in the past 20 years. First, it was
\nlisp, which was going to take over the world, but died when it failed in the
\ncommercial world. Second was ???, and third is Ruby. He thinks “agile” is in
\ntrouble like lisp was in trouble. Agile was founded by people who like to
\nprogram. The key thing that was missing from agile is solidarity of action. He
\nran out of time to complete his thoughts.<\/p>\n
Coby R. announced the LA Ruby Conf – April 4th, 2009<\/p>\n
Justin Graham showed a working example of Adhearsion (the Ruby telephone
\nframework for Asterik).<\/p>\n
Pat Eyler – Ruby Brigades. You should participate in your local Ruby Brigade so that you can strengthen the community. It’s a chance to grow and learn. The best way to learn is to teach others. Simply show up. It’s discouraging when someone organizes a group and no one shows up. Get on the mailing list. Don’t just subscribe. Ask questions. Answer questions. Be involved. Give a lightning talk at the meeting.<\/p>\n
There are two types of meetings: Ones that are a launchpad, and ones that are a destination. Don’t let your meetings become a destination. Make the world a better place.<\/p>\n","protected":false},"excerpt":{"rendered":"
