<p>A while ago, I created some simple command buttons in Octoprint to help with bed levelling, by hopping to particular points on the bed. I realised that what I actually want to do is move Z up 10mm, move, and then home Z though, to avoid ploughing the nozzle along the bed if the level is badly off.</p>
<p>So I did t... | <p>NO if you want to smooth your print, gently heat the plastic and with a utensil smooth out the plastic. A hair dryer is a good way of doing this but be careful to only lightly melt the outside of the model.</p>
| <p>Nail polish contains acetone. It melts PLA, so yes you <em>could</em> damage it. Google acetone vapor batch to read up on a safer way to do the job.</p>

<p>When commiting to SVN I can add a top level commit message to detail what is being committed, but I would ideally like a means to comment on the individual files and what has changed within them. I have seen something similar in previous employment, but this was using CVS (and I can't recall whether this was achiev... | <p>I would just do this in the individual commit message. <a href="http://tortoisesvn.tigris.org/" rel="nofollow noreferrer">TortoiseSVN</a> has filename autocompletion so that greatly aids in this.</p>
<p>Another thing you could do is svn st before you commit and copy/paste the filenames into your commit message.</p>... | <p>That kind of result could be obtain if there is some rules regarding the way comments are written inside each of the committed files. These comments can after that be extracted by a svn trigger.</p>

<p>I have an List and I'd like to wrap it into an IQueryable.</p>
<p>Is this possible?</p>
| <pre><code>List<int> list = new List<int>() { 1, 2, 3, 4, };
IQueryable<int> query = list.AsQueryable();
</code></pre>
<p>If you don't see the <code>AsQueryable()</code> method, add a using statement for <code>System.Linq</code>.</p>
| <p>Use the <code>AsQueryable<T>()</code> extension method.</p>

<p>What is the best solution to sanitize output HTML in Rails (to avoid XSS attacks)?</p>

| <p>Personally I think it's not a small decision to accept any HTML entry in any web app. You can test for white/blacklisted tags as much as you like, but unless you're testing for correct nesting, someone could enter a series of closing tags, for example</p>

<p>Why does Visual Studio declare new classes as private in C#? I almost always switch them over to public, am I the crazy one?</p>
