<li>Yes. Unless there's a feature we really need in a beta version.</li>
<li>There's no point using a beta version in dev if you aren't certain you'll use it in production. That just seems like a wasted exercise</li>
<li>I'll use the patch. Why write code for something you've paid for?</li>

<p>I'm astonished that the <a href="http://commons.apache.org/collections/" rel="nofollow noreferrer">Apache Commons Collections</a> project still hasn't got around to making their library generics-aware. I really like the features provided by this library, but the lack of support for generics is a big turn-off. There ... | <p>There are contributions.

<p>For my work i use both, apache collections and google collections. </p>
<p>can you explain more about why you can't use google collections?</p>

<p>What is the best way to unit test a method that doesn't return anything? Specifically in c#.</p>
<p>What I am really trying to test is a method that takes a log file and parses it for specific strings. The strings are then inserted into a database. Nothing that hasn't been done before but being VERY new to TDD I am... | <p>If a method doesn't return anything, it's either one of the following</p>

<li><strong>imperative</strong> - You're either asking the object to do something to itself.. e.g change state (without expecting any confirmation.. its assumed that it will be done)</li>

<p>For Example: </p>
<p>In My case its <code>_Log</code> is the instance and <code>LogMessage</code> is the method to be tested:</p>

<p>I am using VSTO 3.0 and the ribbon designer gives me a ribbon that is apparently shared across documents.</p>

<p>I'm planning software that's an OLAP application at its heart (it helps analyse metering data) and is going to have some kind of star schema for its database, because the stored values will be looked at from different angles (time, source, type etc.) and the requests will be asking for aggregated data along these di... | <p>Some DB engines that do not directly support bitmap indexes still have star optimisations that can do this type of query without hitting the fact table.
