(note: to accomplish this I believe minimal setup through Puppet could get things in place - this would be for deployed env. - everything else would have a Readme)</p> <p>&lt;(soon) deprecated&gt;</p> <p>For <strong>drush_make .info inject</strong>...

We need to change the way we look at the server - web-servers are really build-servers.</p> <hr /> <h4>Intro</h4> <p> Lately at <a href="http://www.allplayers.com">AllPlayers.com</a> I have been spending a lot of time working on API's for our site and spending some time making Drupal talk <em>web</em>. Luckily, this is something that is being thought about a lot in the community (see: <a href="http://groups.drupal.org/wscci">WSCCI</a>, <a href="http://drupal.org/project/services">services.module</a>); but, there are some interesting growing pains: <!-- more --></p> <p> The <em>connection</em> to Drupal: There are a variety of ways to <a href="http://drupal.org/project/modules?filters=tid%3A52">connect to external sites</a> and obviously "the way the web should work", but I get the explicit feeling that many of types of connections are "toys". As a site administrator we built out a DLAMP (Drupal, Linux, Apache, MySQL, PHP) install because we are <em>serious</em> about building a web-app! In our engineering efforts, we are probably only slightly interested in handing over our data to 3rd party services, so likely our next interest is in taking on the data for ourselves (which is no small matter).</p> <h4>Get the data</h4> <p> So, we've committed ourselves to "<a href="http://en.wikipedia.org/wiki/Big_data">big data</a>"; great - how do we do it?! Honestly - look towards to the industry leaders; short of a major engineering effort (which perhaps you should be looking at hadoop, hbase, and map-reduce), we are here for Drupal - and that's gonna make this fast and powerful: <a href="http://drupal.org/project/feeds">feeds</a>! Target an endpoint, upload a file, or configure the plugin an do what you want, then parse that data with a processor (e.g. XPath, QueryPath, CSV mapping, or build your own). It's a little like magic! (if you don't believe me, maybe a <a href="http://developmentseed.org/blog/2009/dec/15/importing-and-aggregating-stuff-feeds">demo</a> could convince you. Now let's get a little more technical...)</p> <h5>Oh the pain...</h5> <p> You've got the data but, was that all there was to it? Mostly... but, because we are good researchers we note something about feeds requests: <a href="http://drupalcode.org/project/feeds.git/blob/refs/heads/master:/libraries/http_request.inc#l86">they're pretty good</a>, but there turns out to be a variety of different ways to do essentially the same thing:</p> <ul> <li><a href="http://api.drupal.org/api/drupal/includes--common.inc/function/drupal_http_request/7"><code>drupal_http_request</code></a></li> <li><a href="http://drupalcode.org/project/wbapi.git/blob/refs/heads/master:/wbapi.request.inc#l164">World Bank API</a> (depends on <code>drupal_http_request</code>)</li> <li><a href="http://drupalcode.org/project/acquia_connector.git/blob/refs/heads/7.x-1.x:/acquia_agent/acquia_agent.module#l553">Acquia Connector</a> which uses <a href="http://api.drupal.org/api/drupal/includes--common.inc/function/xmlrpc/7">XML-RPC</a> (depends on <code>drupal_http_request</code>)</li> <li><a href="https://github.com/pantheon-systems/pantheon7/blob/master/modules/pantheon/pantheon_api/pantheon_api.inc#L113-168">Pantheon System API</a></li> </ul> <p> Some observations: <em>the Drupal way</em> seems to be <code>drupal_http_request</code> but, there is also a distinct lack of PEAR dependencies like <a href="http://pear.php.net/package/HTTP_Request2">HTTP_Request</a>; a nice place to ruminate.</p> <h4>Expose your data</h4> <p> Data acquired! But we want to share (easy): <a href="http://drupal.org/documentation/modules/field-ui">fields</a> and <a href="http://drupal.org/project/views">views</a>. However, as a respecting netizen you want to share semantically! Drupal already comes <a href="http://www.lullabot.com/articles/how-does-rdf-work-drupal-7">feature packed for the web</a>, but we also want to share through API's. Luckily contrib space has this "solved" with <a href="http://drupal.org/project/services">services</a>, where we can expose our data through a variety of <a href="http://drupalcode.org/project/services.git/tree/refs/heads/7.x-3.x:/servers">servers</a> and varieties of <a href="http://drupalcode.org/project/services.git/blob/refs/heads/7.x-3.x:/servers/rest_server/includes/rest_server.views.inc#l25">formats</a>.</p> <p> Thus we can do something like <a href="https://gist.github.com/affc9864487bb1b9c918">this</a>: <code>GET</code> http://drupal6-services/services/plist/node/1.json and expect</p> <pre><code>{ "changed": "1286592762", "language": "", "uid": "0", "type": "story", "status": "0", "nid": "1", "created": "1286592762" ... } </code></pre> <p>amazingly powerful! (it is also worth noting that the services endpoint can pull from views as well!)</p> <h5>Oh the pain...</h5> <p> The story so far has gotten us everything we need <em>very quickly</em>, but as consumers of <a href="https://dev.twitter.com/docs/api">many</a> <a href="http://developers.facebook.com/docs/reference/rest">public</a> <a href="http://www.twilio.com/docs/api/rest/">APIs</a> we quickly note that what we are leaking is Drupal through exposing endpoints. This is actually fairly useful to developers of Drupal, but is probably pretty useless to someone consuming your <em>product</em>, therefore we need to take <a href="http://drupalcode.org/project/services.git/blob/refs/heads/7.x-3.x:/services.services.api.php">configure (or theme)</a> the exposed services.</p> <p> Additionally, given a glimpse of <a href="http://www.garfieldtech.com/blog/web-services-initiative">web services future of Drupal</a> this seems particularly pertinent! <a href="http://groups.drupal.org/wscci">WSCCI</a> (Web Services Context Core Initiative) is the holding place for the <em>high performance REST server</em>.</p> <h4>Data and the front-end interaction</h4> <p> I probably don't share very much, but I have a <a href="http://twitter.com/#!/imetchrischris/status/116723898380328960">love affair</a> with javascript; and given the amazing <a href="http://slides.html5rocks.com">HTML5 features</a> and great <a href="http://microjs.com">javascript libraries</a> (<a href="http://jquery.com/">jQuery</a> is just the tip of the iceberg - or the first taste depending on how you look at it) - there is a bright future in the browser! So bright in fact: I am of the opinion that "web-pages" should be delivered as apps! There are a lot of great tools to facilitate the concept of a client side app, often examples of this are seen in the <a href="https://chrome.google.com/webstore">Chrome web store</a> (some neat technologies include the <a href="http://www.w3.org/TR/html5/offline.html">cache-manifest</a>).</p> <p> This leaves me wondering: where exactly does the theme layer live? Particularly, as in a traditional sense, the theme layer seems to live "in the browser", which means that any processing done server side to render CSS, JS, and/or HTML would be in the <em>delivery of an application</em> - the version of which the client is requesting to be delivered by the server.</p> 2010-11-26T00:00:00-06:00 http://imetchrischris.com/drupal-camp-austin-re-cap/drupal-camp-austin-re-cap <div><a href="http://2010.drupalcampaustin.org/">Drupal Camp Austin</a> (DCA) was excellent - there was a great showing of drupalist and no shortage of excitement and learning.

Now, without too much <a href="http://chrischris.posterous.com/what-apps-really-are-services">history</a> I am <a href="http://chrischris.posterous.com/past-225">kindof</a> a services <a href="http://chrischris.posterous.com/omg-ecmascript-is-js-and-a-ws-e4x-woohoo">nut</a>! However, I do not know how I missed <a href="http://alexbarnett.net/blog/archive/2007/03/13/Does-REST-need-a-WSDL_3F00_.aspx">this fight</a> on the <a href="http://www.w3.org/TR/wsdl">WSDL</a>, <a href="http://en.wikipedia.org/wiki/Representational_State_Transfer">REST</a>, <a href="http://en.wikipedia.org/wiki/Web_Application_Description_Language">WADL</a> acronym soup debate. As it turns out often enterprise-y tools do an amazing job at creating compatible (and even usable) web services endpoints, often in the form of SOAP with WSDL&#39;s describing the endpoint. A little investigation here reveals though just how hard it is to integrate a REST-ful endpoint to these service (often the value add of the extensible schema and type definitions quickly negates the simplicity of the REST). IMO this really leaves people in two camps - those with the automated *tools* to read the service endpoints (and quickly gain traction on interacting with the objects) and the simplicity of the REST interfaces that have very little overhead since they exploit the existing underlying architecture. I am not going to go into a tizzy here on why this seems really stupid (note to self - I should really write up some thoughts on this...)... because through this research I have stumbled onto a nifty google project: <a href="http://code.google.com/p/rest-api-code-gen/">REST API code-gen</a> (in all its computer science-y acronym laden goodness) - this is really cool (short description <a href="http://blog.tomayac.de/index.php?date=2007-03-12&amp;time=17:11:27&amp;perma=Automatic+Multi+Lang.html">here</a>)!! <p /><div>Bam - Magic!</div><div><img src="http://blog.tomayac.de/images/Google_REST_Compile.png" alt="REST Compile" /></div><div><a href="http://blog.tomayac.de/index.php?date=2007-03-12&amp;time=17:11:27&amp;perma=Automatic+Multi+Lang.html">ref</a></div> <p /><div>Woohoo - bringing robots to simple web services interfaces - I feel the future coming (unless its already dead)!</div> 2010-05-21T00:00:00-05:00 http://imetchrischris.com/i-walked-into-the-office-the-other-day-to-thi/i-walked-into-the-office-the-other-day-to-thi <p><img src="http://imetchrischris.com/images/IMG00165-20100521-0849.jpg" alt="I walked into the office the other day to this" /></p> <p>sent via mobile</p> 2010-05-16T00:00:00-05:00 http://imetchrischris.com/so-much-mandated-technology/so-much-mandated-technology &quot;So much mandated technology...they [generally large companies] just take the [provider] with the most steaks and the most strippers; typically from companies who have expense accounts and sales people who can sell them very expensive application servers over six months.&quot; <a href="http://twit.tv/floss79">http://twit.tv/floss79</a> 2010-05-16T00:00:00-05:00 http://imetchrischris.com/drupal-features-moving-a-cck-content-type-fro/drupal-features-moving-a-cck-content-type-fro <p><img title="3086495495_ab338eecc4.jpg" src="http://farm4.static.flickr.com/3066/3086495495_ab338eecc4.jpg" height="130" alt="3086495495_ab338eecc4.jpg" width="200" />&nbsp;Recently ran into an interesting problem - I wanted to move a <a href="http://drupal.org/project/cck">content type (cck)</a> that I had created from one <a href="http://drupal.org/project/features">feature</a> to another (specifically to move it into a <a href="http://drupal.org/project/spaces">spaces</a> enabled&nbsp;feature to gain some of those benefits - thanks <a href="http://code.developmentseed.org/">devseed</a>!); however, as you might be aware (if you are stumbling across this) features is pretty smart - often *too* smart.&nbsp;When removing the content type from one feature it will effectively remove the content type from your drupal install; whilst if you add the content type to another feature in parallel features will ingeniously mark the other feature you have as a dependency. What we are going to exploit: drupal features caches with a version control system (VCS - I prefer <a href="http://git-scm.com/">git</a>) and <a href="http://drupal.org/project/drush">drush</a>:</p> <p /> <div>vernacular:</div> <div>* laterBranchOrTag - the later time we are trying to get to in our source</div> <div>* earlierBranchOrTag - the time when our feature we are coming *from* was correct</div> <div>* featureNameOld = old feature (to delete from)</div> <div>* featureNameNew = new feature (to be added to)</div> <p><script src="https://gist.github.com/403176.js"></script></p> <div>What we have done - we have basically loaded many of drupal's caches (note: some items like variables, with strongarm, do not use the db for cacheing - this is a different animal)&nbsp;with the feature and CCK defs and then switched the code base beneath it. When the features-update occurs the items that are cached are written out into features code, but in the featureNameNew namespace.</div> <p /> <div>simple enough?</div> <p /> <div>( photo attr: Alex

What shocked me about all of them was how available they were across platforms - particularly mobile. Then I came to quickly realize the only investment in development for each platform was front-end work; the piece they all had in common was the backend. Now, some might be familiar with some patterns that make this possible like <a href="http://en.wikipedia.org/wiki/Model–view–controller">MVC</a>; but what really surprises me is how unbelievably seamless these apps work in the face of having to support different platforms. This leads me to a more philosophical question about touting an &quot;app for that...&quot; - really what we are seeing is that behind many of the good apps there is a terrific service that is capable of being abstracted from that devices interface.</div> <p /><div style="text-align: center;"><img src="http://imetchrischris.com/images/graphic.png" alt="What apps really are - services" /></div><p />Caveat Emptor: Its probably very short sighted to assume that this is a one sided conclusion, but I think there are some great reasons to follow this pattern; there are many great reasons to have a fantastic UI, but when thinking about reaching the maximum audience it is comforting to know that following this pattern can help development remain agile in the face of new device releases (see: iPad). 2010-04-02T00:00:00-05:00 http://imetchrischris.com/data---its-really-important!/data---its-really-important!
