			<content:encoded><![CDATA[<p>Below are some questions in various subjects I encounter either through day to day work or reading tech articles and blogs.</p>
<p>I will put the subjects in bullets and when i find the answers i will hyper-link them to another post where I write the answer I found.</p>
<ul>
<li>How exceptions are implemented by compilers? How does the assembly generated by the compiler look like?</li>
<li>In public key cryptography, what is the algorithm used to raise very large numbers to very large exponents? I know it uses assembly to do bit manipulation but what is the exact algorithm.</li>
</ul>
<p>If anyone can point me to some reference to fulfill my lust to learn about any of the subjects above, I’d appreciate it.</p>

			<content:encoded><![CDATA[<p>The &quot;remember me&quot; option in asp.net 2.0 will remember the user for as long as the <em>Timeout</em> period set in the forms authentication in the web.config</p>
<p>It&#8217;s really weird how it works as it is now. Below is an excerpt from a post found on the DotNukeForum:</p>
<blockquote><p><em>How forms authentication cookies worked under asp.net 1.1</em></p>
<p>session cookies expiration = current datetime +the forms timeout value e.g. 60      <br />persistent cookies expiration = current datetime + 50 years</p>
<p>&#160;</p>

			<content:encoded><![CDATA[<p>Notes from Code Complete</p>
<ul>
<li>Use error-handling code for conditions you expect to occur; use assertions for conditions that should never occur</li>
<li>Use assertions to document and verify preconditions and postconditions</li>
<li>Throw exceptions at the right level of abstraction; include all information that led to the exception</li>
<li>Always have a mechanism to log application errors and a way to read that log.</li>

			<content:encoded><![CDATA[<ol>
<li>Press and hold down the <code>Alt</code> key.</li>
<li>Press the <code>+</code> (plus) key on the <em>numeric keypad</em>.</li>
<li>Type the hexadecimal Unicode value.</li>
<li>Release the <code>Alt</code> key.</li>
</ol>
<p>Note that this method will only work if you have the following registry key set to the correct value..<br />
under <code>HKEY_Current_User/Control Panel/Input Method</code>, set <code>EnableHexNumpad </code> to <code>1</code></p>
<p>Use the <em>Character Map</em> to find the hexadecimal Unicode values for different characters.</p>
<p>Also, it&#8217;s worth noting that if you are using <em>MS Word</em> you can simply type in the Unicode hex value first and then press <em>Alt+x. </em>The hex number will be replaced by it&#8217;s equivalent Unicode character automagically.</p>
