<div class="intro">
<p>Before start, I must say I know Cappuccino and jQuery are no more comparable than Cocoa and the C++ standard library. One is oriented for user interface while the other is and helper for low level programming. Nonetheless I used these two to make the same web application. This is why I compare the experience I had with each of them for this specific task.</p>
</div>
<p>I made a web version of my dashboard widget <a href="http://yannesposito.com/softwares/ypassword">YPassword</a>. It is a simple widget to manage your online password with a <em>strong</em> security and with a totally portable way. It is not intended to replace a <em>keychain</em>. It is more a password generator.</p>
<p>The first was made from the code of my dashboard widget and with some jQuery. You can try it <a href="http://yannesposito.com/YPassword.old">here</a>. I then made a second version with the <a href="http://cappuccino.org">Cappuccino</a>. You can try it <a href="http://yannesposito.com/YPassword">here</a>.</p>
<h2 id="what-this-widget-do">What this widget do?</h2>
<div class="intro">
<p>If you don’t mind about what does my widget and just want to know how the two frameworkcompare, you should go directly to the <a href="#cappuccino">next part</a>.</p>
</div>
<p>I manage my password on many site with a simple method. I remember a strong master password. And my password is mainly <code class="ruby">hash(masterPassword+domainName)</code></p>
<p>In reality I need a bit more informations to create a password:</p>
<ul>
<li>A master password,</li>
<li>an URL,</li>
<li>a maximal password length,</li>
<li>the kind of output base64 or hexadecimal,</li>
<li>how many times my password could have leaked.</li>
</ul>
<p>The result password is this:</p>
<div class="sourceCode" id="cb1"><pre class="sourceCode ruby"><code class="sourceCode ruby"><a class="sourceLine" id="cb1-1" title="1">domainName=domaine_Name_Of_URL(url)</a>
<a class="sourceLine" id="cb1-2" title="2">hash=sha1( masterPassword + leakedTimes + domainName )</a>
<a class="sourceLine" id="cb1-3" title="3"><span class="kw">if</span> ( kind == <span class="st">'base64'</span> )</a>
<a class="sourceLine" id="cb1-4" title="4"> hash=base64(hash)</a>
<a class="sourceLine" id="cb1-5" title="5"><span class="kw">end</span></a>
<a class="sourceLine" id="cb1-6" title="6"><span class="kw">return</span> hash[<span class="dv">0</span>..maxlength]</a></code></pre></div>
<p>In fact depending of websites, some give some strange constraint to your password:</p>
<ul>
<li>minimal length,</li>
<li>maximal length,</li>
<li>must not contain a special character,</li>
<li>must contain a special character,</li>
<li>etc…</li>
</ul>
<p>And if you want to change your password the <em>leak number</em> is here for that. All informations such as user name, maximal length can be stored in a public file. The only real secret is the master password.</p>
<p>If you want to know even more details you can always look at some of my old blog entries:</p>

</ul>
<h2 id="cappuccino">Cappuccino</h2>
<p>First, I’d like to say Cappuccino applications look simply awesome. It is like having a Cocoa application in your web browser. And this is <em>great</em>.</p>
<p>I also must admit I enjoyed making my application with Cappuccino. It is like programming for an iPhone application. If you are a bit familiar with Cocoa, you feel at home. If you don’t know anything about Cocoa, I suggest you to look at it. This is a really <em>great</em> framework to make User Interface. I am not a specialist, but I have done some MFC, java Swing<a href="#fn1" class="footnote-ref" id="fnref1"><sup>1</sup></a> and WXWindows User Interfaces (some years ago). And I must say, Cocoa is far better than those.</p>
<p>Cappuccino is a great web application oriented development. But there was also some drawbacks</p>
<p>Things I liked:</p>
<ul>
<li>It looks great</li>
<li>It was fun to program</li>
<li>It was like programming a Mac application</li>
<li>I could have done the User Interface using <a href="http://developer.apple.com/technologies/tools/xcode.html">Interface Builder</a>.</li>
</ul>
<p>Some things I didn’t like:</p>
<ul>
<li>I made some time to understand how to handle the <code>onChange</code> on the text fields.</li>
<li>Documentation lacked a bit of organisation.</li>
<li>It doesn’t work on iPhone.</li>
<li>It weighted 11MB to deploy.</li>
<li>It weight 1.3MB to load.</li>
</ul>
<p>I didn’t use bindings because I believe they are not ready by now.</p>
<h2 id="jquery">jQuery</h2>
<p>The jQuery version of YPassword is not as finished as the Cappuccino one. Because, there is no <em>slider</em> directly with jQuery. I’d have to use jQueryUI. And I believe, using it will make the application weight far more than the today 106KB.</p>
<p>To make this version I simply copied my widget source code and adapted it. It was straightforward. But jQuery is not an <em>application oriented framework</em>. It is more a “<em>dark side</em> javascript animation framework”<a href="#fn2" class="footnote-ref" id="fnref2"><sup>2</sup></a>.</p>
<p>I don’t have too much to say about the jQuery version. But this was way more <em>low level</em> programming than Cappuccino.</p>
<h2 id="my-conclusion">My conclusion</h2>
<p>If you want to make an iPhone compatible web application just don’t use Cappuccino yet. If you want to make <em>simple</em> application like mine, I also believe, Cappuccino is a bit too much.</p>
<p>If you want to make a complex web oriented application, Cappuccino is a great choice. But you may have some difficulties to begin programming with it.</p>
<p>Finally, to terminate my web version of my widget, I’ll give a try to Dashcode 3. It seems to be a good alternative to create web widgets. I don’t know if Dashcode 3 is portable on non webkit browser. But if it is, it could be the end of projects like Cappuccino and Sproutcore.</p>
