            <p>At <a href="http://www.radinks.com/">Rad Inks</a> we, have just announced version 2.01 of the Rad SFTP Applet. It is a replacement for desktop FTP and Secure FTP clients. All you need is just one copy of the applet to replace any number of copies of your current desktop FTP or SFTP client.</p>
            <p>The Rad Inks Secure FTP client makes use of the SSH FTP protocol, which despite the similarity in name with the File Transfer Protocol is a much more secure system. <a href="../../php/ftp/security.php">FTP is totally insecure</a>. If you use it, all the data and commands will be transferred between the client and the server in plain text. Therefore with each FTP connection the user name and password will be transmitted without any encryption. If you care about the security of your web server you wouldn't be using FTP. It's as simple as that.</p>
            <p>Because the Rad SFTP applet runs in the context of the web browser, anyone using the system does not need to install any software on his own computer. Since the applet is light weight it starts up almost instantly and can rival the start up speed of a desktop client.</p>
            <p><a href="http://www.radinks.com/sftp/secure.php">So what's new in this release</a>? it's has a couple of small bug fixes and a minor feature enhancement.</p>

            <p>Which programming language to use is often a matter of religious choice. But for certain tasks certain languages are much better than others. For example when it comes to creating web applications PHP can claim to be much superior to most yet when it comes to number crunching PHP lags far behind.</p>
            <p>In the past, the perception was that Java isn't suited for number crunching tasks either. Those days are long gone. My <a href="../../java/primes.php">java implementation of the Sieve of Eratosthenes</a> to find prime numbers runs much much faster than the <a href="../../php/primes.php">PHP counter part</a>. The java version can find primes smaller than 1,000,000 in about 3 seconds while the PHP version takes more than a minute. That's a difference of 20X.</p>
            <p>The same algorithm was implemented as a <a href="../../mysql/primes.php">MySQl stored procedure</a> so that the numbers are available in a form that can be easily searched. That code takes around 4 minutes to find the same set of primes. So clearly for this particular purpose Java is far superior to others. However if you compared against Fortran you will find that java is inferior.</p>
