<p>If no pretty solution exists ... | <p>Master Pages are based upon Usercontrols, therefore they cannot be shared across applications. </p>
<p>That said, Dan Wahlin has a way around that particular limitation <a href="http://weblogs.asp.net/dwahlin/archive/2005/11/16/430779.aspx" rel="noreferrer">listed on his blog</a>. </p>
| <p>There are no pretty solutions to this problem.</p>
<p>What you can do is put it into a separate web application project and pre-compile it. Then take the precompiled dlls and ILMerge them into a single dll that you can reference in your app.</p>

<p>My understanding of Hibernate is that as objects are loaded from the DB they are added to the Session. At various points, depending on your configuration, the session is flushed. At this point, modified objects are written to the database.</p>
<p>How does Hibernate decide which objects are 'dirty' and need to be wr... | <p>Hibernate does/can use bytecode generation (CGLIB) so that it knows a field is dirty as soon as you call the setter (or even assign to the field afaict).</p>
<p>This immediately marks that field/object as dirty, but doesn't reduce the number of objects that need to be dirty-checked during flush. All it does is impa... | <p>These answers are incomplete (at best -- I am not an expert here). If you have an hib man entity in your session, you do NOTHING to it, you can still get an update issued when you call save() on it. when? when another session updates that object between your load() and save(). here is my example of this: <a href... | 10,816 |
<p>I'm writing a url rewrite in django that when a person goes to <a href="http://mysite.com/urlchecker/http://www.google.com" rel="nofollow noreferrer">http://mysite.com/urlchecker/http://www.google.com</a> it sends the url: <a href="http://ww.google.com" rel="nofollow noreferrer">http://ww.google.com</a> to a view ... | <p>Try this instead:</p>
<p><code>(r'^urlchecker/(?P<url>.+)$', 'mysite.main.views.urlchecker'),</code></p>
<p>This differs from yours in that:</p>
<ul>
<li>It will take anything after 'urlcheck/', not just "word" characters.</li>
<li>It does not force the url to end in a slash.</li>

<p>I'm working on a something related to roughset right now. The project uses alot of sets operation and manipulation. I've been using string operations as a stop gap measure for set operation. It has worked fine until we need to process some ungodly amount of data ( 500,000 records with about 40+ columns each ) throug... | <p>.NET 3.5 already has a native set data type: <a href="http://msdn.microsoft.com/en-us/library/bb359438.aspx" rel="noreferrer">HashSet</a>.

<p>When are objects or something else said to be "first-class" in a given programming language, and why? In what way do they differ from languages where they are not?</p>
<p>When one says "everything is an object" (like in Python), do they indeed mean that "everything is first-class"?</p>
| <p>In short, it means there are no restrictions on the object's use. It's the same as
any other object.</p>
<p>A first class object is an entity that can be dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have. </p>
<bl... | <p>IMO this is one of those metaphors used to describe things in a natural language. The term is essentially used in context of describing functions as first class objects. </p>
