In ATL these attributes were a compiler trick. They were not a core part of the platform like attributes in C#. They were also more confusing to debug than macros's and the method of dumping generated attribute code was a hassle.

A test confirms that GCC 4.2.3 will simply compare with the overflowed result:

There's object-based databases(Gemstore, for example). Google's Big-Table and Amason's Simple Storage I am not sure how you would categorize, but both are map-reduce based. |
In C, you use a void in an empty function reference so that compiler has a prototype, and that prototype is "no arguments". In C++, you don't have to tell the compiler that you have a prototype because you can't leave out the prototype. |
Also a little silly, but you could try picking an arbitrary day and embedding each time in it, using `datetime.datetime.combine`, then subtracting:

>>> t2 = datetime.time(18,20,59)
>>> dummydate = datetime.date(2000,1,1)

I realize your question pertains to C++, but when it comes to C the answer can be found in K&R, pages 72-73:

Furthermore, if a function declaration does not include arguments, as in

To add to Jim's answer you could also use the word list and randomly replace certain characters with symbols (an @ for an A, a 0 (zero) for an O or a 5 for an S) and/or remove the vowels from the words.

- p@per&b0y32H@t
Still mostly human readable. |
You have to wrap the word in a span to accomplish this. |
Multiple Eval Fields in Gridview ItemTemplate |

I just learned a new trick and thought I'd share it (and try to find an *even better* way).

What you are looking for is a pseudoclass that doesn't exist. There is :first-letter and :first-line, but no :first-word.
You can of course do this with JavaScript. Here's some code I found that does this: [http://www.dynamicsitesolutions.com/javascript/first-word-selector/][1]

Use the [strong][1] element, that is it's purpose:
<div id="content">
<p><strong>First Word</strong> rest of paragraph.</p>
</div>
Then create a style for it in your style sheet.
#content p strong
{
font-size: 14pt;
}

There isn't a plain CSS method for this. You might have to go with JavaScript + Regex to pop in a span.
Ideally, there would be a pseudo-element for first-word, but you're out of luck as that doesn't appear to work. We do have :first-letter and :first-line.
You might be able to use a combination of :after or :be... |
I had previously used this (bad, I know):

It seems to me obfuscation is an idea that falls somewhere in the "security by obscurity" or "false sense of protection" camp.

I would recommend following the [inbox zero](http://video.google.com/videoplay?docid=973149761529535925) approach advocated by 43 folders. Joel Spolsky apparently uses it and a lot of people feel it's a great way of decluttering and organising your email life :-). |
