smoke Ben Schwarz @benschwarz http://github.com/benschwarz Friday, 1 May 2009 Hi!

Lunch time Friday, 1 May 2009 Starting with a story... It was lunch time.

2pm Friday, 1 May 2009 It was well and truly past eating time

1 Hour Friday, 1 May 2009 I had one hour. What do you do?

Code lunch Friday, 1 May 2009 No need for eating. What will I do?

Sinatra http://sinatrarb.com Friday, 1 May 2009 We use Sinatra!

Yahoo Pipes http://pipes.yahoo.com Friday, 1 May 2009 Annd data from other peoples websites. No RDBMS for me!

Yahoo Pipes • Get data from multiple web based sources • Mash it up a bit • Provide a single output in either JSON or XML Friday, 1 May 2009

YQL Friday, 1 May 2009

YQL? Friday, 1 May 2009 Yeah, its kinda SQL for the web. Most people don’t even really like writing SQL

@lachlanhardy Friday, 1 May 2009 Lachlan convinced me to have a second look at YQL after slagging it o

Time to start Friday, 1 May 2009

Friday, 1 May 2009 The code isn’t important, but basically it just talks to a yahoo pipe that I made up.

Friday, 1 May 2009 I made “munch”. It pulls from various recipe and cooking related web sites like taste.com.au and friends. It reads RSS and scrapes sites. Pretty simple.

2:46pm Friday, 1 May 2009 46 six minutes later. I’d been eected.

“I need a new web site” - Me, probably avoiding real work Friday, 1 May 2009 I wanted to blog about this, sadly my blog is cached ﬁles sitting on a slicehost account. Mephisto isn’t even running any longer.

Friday, 1 May 2009 I quickly threw a grid together.

HTML5 Friday, 1 May 2009 I wanted to experiment.

Sinatra Friday, 1 May 2009 a bit more sinatra.

Friday, 1 May 2009 I knew that I didn’t want to write everything then link it in to my blog, I wanted to write it once and be able to keep it updated.

Friday, 1 May 2009 of course, I could’ve just got a tumblr account. That didn’t let me use sinatra or mess around with HTML5.

Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

Delicious Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

All Delicious Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

All Delicious Twitter Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

All Delicious When I wasn’t talking to @someone Twitter Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

All Delicious When I wasn’t talking to @someone Twitter Flickr Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

All Delicious When I wasn’t talking to @someone Twitter Selected (special tag) Flickr Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

All Delicious When I wasn’t talking to @someone Twitter Selected (special tag) Flickr ? Friday, 1 May 2009 It was getting easier, I had constraints around the use of my data

Friday, 1 May 2009 The yahoo pipe looked like this. A bit of a mental leap.

Friday, 1 May 2009 Some things stood out. like union, I could join multiple sources of data together and output them as one

Friday, 1 May 2009 or sort them by the publication date

Friday, 1 May 2009 and ﬁlter out the tweets to people. Sure a regex would’ve been smarter, but this was 90% good enough

Friday, 1 May 2009 I started thinking about my process, the data coming from all over the place.

“What if I could write something like pipes?” Friday, 1 May 2009 I wanted to do something myself (again)

“What if I could write a ruby block based DSL?” Friday, 1 May 2009 I’d never written one, totally a good time to jump right in head ﬁrst.

“What if you got plain old Ruby objects?” Friday, 1 May 2009 If the data returned could be ruby, irrespective of what format it started as... it would be awesome

Or JSON Friday, 1 May 2009

Friday, 1 May 2009 Enter, “Smoke.”

Smoke Friday, 1 May 2009 Enter, “Smoke.”

Friday, 1 May 2009 A search, which I named “ruby” uses yql and does a web based (search engine) search for the keyword of “ruby”

Friday, 1 May 2009 and hey, I’m gonna grab the RSS feed from slashdot. “emit” will transform the objects that my feed returns. I’ll rename any keys of link to url, this will make my data mind-map better

Friday, 1 May 2009 The whole point of this was to bring these multiple feeds together, re interpret them as one common feed.

Friday, 1 May 2009 This creates a new “source”, it’ll be named “ruby_useless_joined”. It can be reﬁltered if required

Creates Friday, 1 May 2009 This creates a new “source”, it’ll be named “ruby_useless_joined”. It can be reﬁltered if required

Friday, 1 May 2009 That can be extended and the items from the two sources can have some transformations as well.

Friday, 1 May 2009 That accessor

Friday, 1 May 2009 Get the ﬁrst item output (output is an array of the items from the source)

Friday, 1 May 2009 It gives us this

What just happened? Friday, 1 May 2009 Thinking a little more about what actually just happened. It parsed the data to a ruby object, irrespective of the format it came in as.

What just happened? • Queried the web Friday, 1 May 2009 Thinking a little more about what actually just happened. It parsed the data to a ruby object, irrespective of the format it came in as.

What just happened? • Queried the web • Auto-magically parsed the data Friday, 1 May 2009 Thinking a little more about what actually just happened. It parsed the data to a ruby object, irrespective of the format it came in as.

What just happened? • Queried the web • Auto-magically parsed the data • Returned a clean object Friday, 1 May 2009 Thinking a little more about what actually just happened. It parsed the data to a ruby object, irrespective of the format it came in as.

Friday, 1 May 2009 We can also output JSON

Friday, 1 May 2009 Its string escaped and not worth reading, but you could pass this through a web based app straight down to javascript

Method chaining Friday, 1 May 2009 Methods can also be chained without invoking a new source or joining sources together

Friday, 1 May 2009 Here we can get a predeﬁned source, shorten the result set and re sort it.

Transformations Amount of items Truncate By a single key Sort One key to another Rename Items that match regex Keep Items that match regex Discard Ruby (default) or JSON Output Friday, 1 May 2009 Right now, you can do these things

YQL Definitions Friday, 1 May 2009 I’m looking at adding support for YQL deﬁnitions

Friday, 1 May 2009 They look like this, I’ve never written one, but it doesn’t look too hard. You can add search to your own preexisting site / rss etc

http://github.com/spullara/yql-tables Friday, 1 May 2009 There are a collection of community provided yql deﬁnitions hosted on github

All these fucking web sites Friday, 1 May 2009 Need I say more?

My message Friday, 1 May 2009 Forgetting all the stu about pipes, yql and smoke, I want you to try something

“Re-interpret the web” Friday, 1 May 2009 Reconsider data, re-represent it to your own needs.

Thanks Friday, 1 May 2009
