When the IPhone first came out, I signed up as a developer but never downloaded the SDK. Today, I took the time to download the SDK to test the emulator for the recent [...]]]></description>

		<description><![CDATA[Ages ago we had a system that used MySQL&#8217;s built in DES3 encryption. It made coding applications in multiple languages easy because we could send it a string with a key and it would be encoded in the database. It wasn&#8217;t secure if someone got hold of the code and the database, but, rather than [...]]]></description>

		<description><![CDATA[Perl has very powerful capabilities for dealing with structures.  PHP&#8217;s support of those structures was based on Perl&#8217;s wisdom.  Python went a different direction. Perl pack/unpack definitions PING_FORMAT =&#62; &#8216;(a4n2N2N/a*)@245&#8242;; TASK_FORMAT =&#62; &#8216;a4NIN/a*a*&#8217;; RETR_FORMAT =&#62; &#8216;a4N/a*N&#8217;; ENCPAYLOAD_FORMAT =&#62; &#8216;Na*&#8217;; PHP pack/unpack definitions define(&#8216;TASK_FORMAT&#8217;, &#8216;a4NINa*a*&#8217;); define(&#8220;ENCPAYLOAD_FORMAT&#8221;,&#8217;Na*&#8217;); For a communications package written in perl that communicates with [...]]]></description>

		<description><![CDATA[File_DB lacked decent file locking and concurrence.  I wasn&#8217;t really willing to move to MySQL which would have solved the problem, but, added a few minor inconveniences along the way.  I needed to store a few thousand bytes for a number of seconds.  While File_DB was wrapped with file locking and assisted by my own [...]]]></description>

		<description><![CDATA[An application I wrote long ago that used File_DB for short-term persistent multithreaded storage had a few issues with concurrency.  I debated rewriting the script to use BerkeleyDB which included proper file locking, but, decided to use Sqlite3 instead as it was closer to SQL and would eliminate a bit of code. The transition was [...]]]></description>
