Does the brand name matter for a SSL EV certificate? <p>Do end users really care if a SSL EV certificate is from VeriSign, Thwate, DigiCert, or etc.?

Regex for names <p>Just starting to explore the 'wonders' of regex. Being someone who learns from trial and error, I'm really struggling because my trials are throwing up a disproportionate amount of errors... My experiments are in PHP using ereg().</p>
<p>Anyway. I work with first and last names separately but for... | <p>This regex is perfect for me.</p>
<pre><code>^([ \u00c0-\u01ffa-zA-Z'\-])+$
</code></pre>
<p>It works fine in php environments using preg_match(), but doesn't work everywhere.</p>

Excel / Quickbooks data to c# <p>I know how to use the OleDbConnection class to open an excel file and select from it, but is there a simple method to read the data from an excel file that has been read into a Stream? And is there also a similar method for QuickBooks?</p>
| <p>Stream? No, Excel files are a complicated mess. Quickbooks, yeah. I found this <a href="http://www.synergration.com/accessbooksrt/" rel="nofollow">ODBC driver</a>, it should support OdbcDataAdapter.</p>

I don't really want to have to compile them because of the number of changes I'm constantly having to make, but in a few cases I've found t... | <p>I'm guessing you're using GHC.

Best practices for project organization with ASP.NET MVC <p>I recently downloaded Rob Conery's excellent <a href="http://blog.wekeroad.com/mvc-storefront/">ASP.NET Storefront reference application</a> and am finding it incredibly instructive. One question that comes to mind is where one should place the Model classes ... | <p>It really depends on the size of the project. There's no inherent value in having a separate "models" assembly, as you can unit test a Web Application project (including MVC projects).</p>

Top-level .mak file for Visual Studio? <p>I've inherited a body of Visual C++ source that consists of about a dozen sub-projects. One of these is an empty "MakeAll" project that depends on all the others, so I can build the entire project by setting the MakeAll project active and selecting "Build All."</p>
