<a href... | <p>In agreement with what Akriss said, pretty much all "super" glue is CA (cyanoacrylate) glue, which is soluble in acetone. PLA itself is does not dissolve in or react with acetone, but the pigments, additives, etc. likely do, so you should wipe with a paper towel or cloth (the latter might be better to avoi... | <p>I've used Acetone before. However that said I've not had the need to remove it from PLA. Not sure how PLA reacts to Acetone.</p>

<p>Within an application, I've got Secret Keys uses to calculate a hash for an API call. In a .NET application it's fairly easy to use a program like Reflector to pull out information from the assembly to include these keys.</p>
<p>Is obfuscating the assembly a good way of securing these keys?</p>
| <p>Probably not.</p>
<p>Look into cryptography and Windows' built-in information-hiding mechanisms (DPAPI and storing the keys in an ACL-restricted registry key, for example). That's as good as you're going to get for security you need to keep on the same system as your application.</p>
<p>If you are looking for a wa... | <p>I wouldn't think so, as obfuscating (as I understand it at least) will simply mess around with the method names to make it hard (but not impossible) to understand the code.

Tests that go against the database should only exist for the purpose of testing the database interface.

<p>I am going to be using Subversion for source control on a new J2EE web application. What directory structure will you recommend for organizing code, tests and documentation?</p>
