<p>I realize this is an old post, but I grabbed it and gave it a try, but I ran into a number of issues with it, which I managed to fix. Here's the code with fixes:</p>

<p>The <a href="http://msdn.microsoft.com/en-us/library/ms724284(VS.85).aspx" rel="nofollow noreferrer"><code>FILETIME</code> structure</a> counts from January 1 1601 (presumably the start of that day) according to the Microsoft documentation, but does this include leap seconds?</p>
| <p>The question shouldn't be if <code>FILETIME</code> includes leap seconds. </p>
<p>It should be:</p>

<p>Do the people, functions, and libraries, who interpret a <code>FILETIME</code> (i.e. <code>FileTimeToSystemTime</code>) include leap seconds when counting the duration?</p>

<p>UTC = (Atomic Time) + (Leap Seconds) ~~ (Mean Solar Time)</p>
<p>The MS documentation says, specifically, "UTC", and so should include the leap seconds. As always with MS, your mileage may vary.</p>

<p>I'm in the process of starting a User Group in my area related to .NET development. The format of the community will be the average free food, presentation, and then maybe free swag giveaway.</p>
<p>What would you, as a member of a user community, look for in order to keep you coming back month to month?</p>
| <p>It's true that some of the talks out there are very rudimentary, unfortunately some times the bulk of your crowd may need that. I consider myself a novice in a lot of fields, but I've attend talks that I thought were beneath me and still people were asking very basic questions. Perhaps it would be worth having a b... | <p>If there isn't beer, its not a good enough user group to attend. The open source guys get this. Their user group meetings are funner, and more dynamic because of this. Just make it BYOB and it'll naturally get better in my experience.</p>

<p>I'm after (short) opinions on FCKeditor vs TinyMCE and whether either or both are XHTML compliant.</p>
<p>In the interest of keeping with the spirit of stackoverflow, if someone has already made your point, just upvote them.</p>
| <p>From my experience FCKEditor does indeed produce XHTML compliant code, but that code is slightly different depending on what browser you're in. Mostly, this was related to the enter key producing either a break or a paragraph, and I think it may have been configurable.</p>
| <p>Afaik, they both allow the browser to mess with the code they produce, which doesn't result in XHTML compliance.</p>

<p>When using Mercurial I sometimes find that it is hard to understand the relationship between changesets when there are thousands of changesets, and sometimes ten or more active branches at any one time.

Note that it takes a <code>git rev-list</code> constraint so you can limit what you see. You definitely want to begin doing such selective picking in the long run when the amount of commits go up.</p>
| <p>I use ClearCase VCS at work and its Version Tree browser could presumably suit you. But, alas, I don't know any separate ready-made tool for this. </p>
