<p>A colleague of mine and I have been discussing how to declare variables in a function.</p>
<p>Let's say you have a class called TStrings (using Delphi for the sake of explanation) that has at least one abstract method and a descendant class called TStringList which obviously implements the abstract method, but it i... | <p>It is a TStringList, so you should also declare it as TStringList (first example). Everything else could confuse you or others that read the code later.</p>
| <p>My vote is the second form - the idea being that TStrings defines a contract/interface and its better to code to them.</p>

<p>I <em>think</em> I know how to create custom encrypted RSA keys, but how can I read one encrypted like ssh-keygen does?</p>
<p>I know I can do this:</p>
<pre><code>OpenSSL::PKey::RSA.new(File.read('private_key'))
</code></pre>
<p>But then OpenSSL asks me for the passphrase... How can I pass it to OpenSSL as a par... | <p>According to the blog post here:</p>

<pre><code>Net::SSH::KeyFactory.load_private_key 'keyfile', 'passphrase'
</code></pre>
<p>By reading the source code I have yet to figure out what the library does to OpenSSL's PKey::RSA.new to accomplish this... And then I go and t... | 29,179 |
<p>I don’t have advanced knowledge in JavaScript, and I am trying to learn how to use Ext JS framework in ASP.NET (C# or VB.NET) environment.

<p>Do you use any of these technologies? Which ones are current and hence sensible to include in a site?</p>
<p>Documentation on any seems to be relatively sparse, and usage of any of them limited, as search engines get better, are they even relevant any more?</p>
| <p>I use microformats whenever I can. Usually it just makes sense anyway, as frequently when I have an address block, I may want to style some elements differently then other elements, and that makes it super easy. It's not like microformats are that hard to figure out.</p>
<p>There has been a couple of instances wh... | <p>I've used all three, but of the lot I'd have to say microformats have the most momentum these days. It has the advantage of being very easy to implement, even as an afterthought, on existing sites. And while there don't seem to be a lot of microformat consumers in the wild at this point, that situation is starting... | 18,164 |
<p>I have a project where there are multiple applications that have some common configuration values. I would like to have a shared .config file that is available to all of the applications using the .Net configuration object model. Each application would also have its own app.config file</p>
