2,196,175 | 2,196,176 | How to read an array and animate the results | <p>I read through several examples of loading an array manually with graphical image file names. The array is then referenced with a few lines of code and the graphical images are animated which looks great.</p>
<p>I have a method that I call that reads data from a SQLITE table and loads an array that contains the file names of the images. The SQL call includes an order by statement to get the images ordered correctly in the array.</p>
<p>I then return from the call to the method and can get the count from the array. I can not figure out how to read the array from the SQL call and get an array built in a way that I can hand it to the UIImage to animate the results. It seems that my main stumbling block is the reading of the text values in the array. I anticipate that I would actually define a new array using initWithObjects and supply the text value of each element in the array in a statement that looks similar to: [UIImage imageNamed: (value of an element from the array)] but am not having any luck reading the initial array and be able to see the clear text value of what was stored initially.</p>

<p>So before I roll my own, does anyone know of a std compliant stringstream which allocates storage on the stack?</p>
<p>I'm thinking of 2 ways to achieve this:</p>
<p>Initially use a statically sized buffer on the stack (probably a template parameter to allow compile-time customization)</p>
<ol>
<li>When space runs out revert to using dynamic storage</li>
<li>When space runs out use <code>alloca</code> to increase the stack storage</li>
</ol>
<p>This will allow quick input into a stringstream for strings shorter than the predetermined size. </p>
<p>A suitable choice for the initial size will mean that things like logging can be achieved without frequent resizing from the heap.</p>

<p>So if another client sends a message, this client will only receive it after sending a message too. I bet you understand me. I have googled for the matter and found out many interesting things such as asynchronous I/O, threading, non-blocking synchronization, concurrent programming and so on.

5,834,224 | 5,834,225 | How can I make a clock tick? | <p>I'm making a clock right now and currently my second hand, minute hand, and hour hand are all drawn graphically using a <code>Line</code> object with an <code>(x0, y0)</code> beginning coordinate and <code>(x1, y1)</code> end coordinate. </p>
<p>What's confusing me right now is how to make the second hand "tick" every time a second passes. That is, how can I update the <code>(x1, y1)</code> coordinate (since the beginning coordinate is always in the center of the clock, we don't need to update it) so that it will move clockwise 6 degrees? This is confusing to me because the direction of the unit circle (and thus the direction of radians) goes counter-clockwise. </p>

3,829,751 | 3,829,752 | The structure of reference type in detail | <p>I know a reference type object is comprised of two parts: a reference to the object, which is essentially a pointer holds the address of the real object, and the object itself that resides on the heap, which might be moved by the GC. The object itself, in turn, consists of two parts: the instance data part (fields) and the metadata part. </p>
<p>I've read numerous pages on the web talking about the storage model of reference type, but none of them gives specific description about how is the metadata part organized. I only learned that it occupied 8 bytes on 32-bit system (which could be observed via profiling), and 4 bytes out of it holds a pointer points to the vtable, but what about the extra 4 bytes? GC marks? built-in attributes? Does anyone know it in detail? I know it's implementation specific, I'm just dying to know how is it actually bit-for-bit organized. For instance, Boehm GC only need a bit as mark, why on earth does CLR need 4 bytes? </p>
