<p>I found the ad on this site to Krypton controls (<a href="https://github.com/ComponentFactory/Krypton" rel="nofollow noreferrer">and here's another one!</a>) and was wondering if any of you using vs.net 05 or 08 are using them and how that's working out.

<p>I'm facing weird "pillars" of underextrusion on outer walls of my XYZ test cube.</p>
<p>On the pictures below I`ve printed PLA test cubes with a 0.4 mm nozzle, 0.2 mm height and 210/50 °C hotends/bed temperature.</p>
<p>Gaps are appearing in walls parallel to both X and Y sides. The pictured sid... | <p>Localized underextrusion usually means you're oozing material somewhere it wasn't supposed to go. Since you have Marlin 2.0, linear advance might help solve that, and in general right retraction amount is important and turning off combing may be needed (combing over infill allows material to ooze).</p>

<p>When designing a REST API or service are there any established best practices for dealing with security (Authentication, Authorization, Identity Management) ?</p>
<p>When building a SOAP API you have WS-Security as a guide and much literature exists on the topic. I have found less information about securing REST en... | <p>As tweakt said, Amazon S3 is a good model to work with. Their request signatures do have some features (such as incorporating a timestamp) that help guard against both accidental and malicious request replaying.</p>

You will, of cou... | <p>REST itself offers no security standards, but things like OAuth and SAML are rapidly becoming the standards in this space. However, authentication and authorization are only a small part of what you need to consider. Many of the known vulnerabilities relating to web applications apply very much to REST apis.

<p>Is there an easy way to iterate over an associative array of this structure in PHP:</p>
<p>The array <code>$searches</code> has a numbered index, with between 4 and 5 associative parts. So I not only need to iterate over <code>$searches[0]</code> through <code>$searches[n]</code>, but also <code>$searches[0]["part0... | <p>Nest two <a href="http://php.net/foreach" rel="noreferrer"><code>foreach</code> loops</a>:</p>

print "$i {\n";
foreach ($values as $key => $value) {
print " $key => $value\n";
}
print "}\n";
}
</code></pre>
| <p>Can you just loop over all of the "part[n]" items and use isset to see if they actually exist or not?</p>

<p>Why does the default IntelliJ default class javadoc comment use non-standard syntax? Instead of creating a line with "User: jstauffer" it could create a line with "@author jstauffer". The other lines that it creates (Date and Time) probably don't have javadoc syntax to use but why not use the javadoc syntax when ava... | <p>I'm not sure why Idea doesn't use the <code>@author</code> tag by default. </p>
