4,738,745 | 4,738,746 | Lazy loading of images with graceful degradation (JavaScript) | <p>Consider a HTML page with a bunch of tags each with their own content. I want to transform each tag to a slide in a slideshow powered by JavaScript. Each tag can contain images and they should be lazy loaded in this slideshow. I don't want all images to load at once.</p>
<p>On the other hand, users with no JavaScript enabled and search engines should just the see markup and all the images. How do I avoid images from loading when JavaScript is enabled, and how do I make sure images are loaded when no JavaScript is enabled?</p>
<p>One way would be to replace all images with this format:</p>
<pre><code><img src="" data-src="myimage.png">
</code></pre>
<p>The problem with that solution is there's no graceful degradation.</p>
<p>Instead, I have to do:</p>
<pre><code><img src="myimage.png">
</code></pre>
<p>The problem with that is that you can't prevent the browser from loading all of the images in the HTML page. I've tried to modify the HTML in several ways when the document is ready. For example, replace all src attributes in images with data-src, empty the entire body and so on.</p>
<p>Do I really have to sacrifice graceful degradation?</p>

<p>Would this be a correct way of doing things? Tests on Linux show that a 50 ms delta is enough during normal operation. On windows, we have to increase it too 100 ms, otherwise, it is thinking the time has changed on every check we do.</p>

<blockquote>
<p>Warning: Illegal string offset <code>'field'</code> in <code>DatabaseCondition->__clone()</code></p>
</blockquote>
<p>And I just can't see how 'field', is an illegal string offset. I'm guessing that I'm just missing something obvious, but if the community can't find a problem, I'll file a bug report.</p>
<p>I interpret the warning as "<em>Under no circumstances is 'field' a valid key</em>". This error would have made sense if I had tried to us for example an array as a key.</p>

1,918,130 | 1,918,131 | Equivalent in C# of "Block values" in other languages | <p>In some languages, almost everything can be used as a value. For example, some languages let you treat a block of code as a unit which can return a value.</p>
<p>In Scheme, a block of code wrapped in a <code>let</code> can return a value:</p>
<pre><code>(define val
(let ()
(define a 10)
(define b 20)
(define c (+ a b))
c))
</code></pre>
<p>Perl 5 also supports blocks as values:</p>
<pre><code>my $val = do
{
my $a = 100;
my $b = 200;
my $c = $a + $b;
$c;
};
</code></pre>
<p>The closest approximation to block values I could come up with in C# was to use a lambda that is cast and immediately called:</p>
<pre><code>var val = ((Func<int>)(() =>
{
var a = 10;
var b = 20;
var c = a + b;
return c;
}))();
</code></pre>
<p>That's not too bad and is in fact exactly what is happening semantically with Scheme; the <code>let</code> is transformed to a <code>lambda</code> which is applied. It's at this point that I wouldn't mind macros in C# to clean up the syntactic clutter.</p>
<p>Is there an another way to get "block values" in C#?</p>
