Arneson 2015-02-20T22:37:41+00:00 https://arnesonium.com/2015/02/prime-number-google-app-engine <p>As I <a href="http://arnesonium.com/2015/02/random-link-rodeo/" title="Random Link Rodeo">mentioned earlier this week</a>, I’ve decided to learn the <a href="http://golang.org/" target="_blank">Go programming language</a>. I’ve also been very interested in Google App Engine, which lets you deploy applications to the cloud from a development sandbox. It’s like magic for web and mobile applications! <!--more--></p> <p>Since I’m so fond of prime numbers, I thought I’d build a web service for calculating them. It does some other fun stuff, too, like figuring out if a number is happy. It also caches primes in the Google Cloud Datastore with some minimal statistics. If you’d like to see the source code for the prime number service, it’s <a href="https://github.com/pymander/prime-json-service" target="_blank">available on GitHub</a>. <!--more--></p> <p>The next thing I did was write the simplest of all WordPress plugins to query the service and return the latest prime number in the sequence. This all happens in a post using the [[nextprime]] shortcode. ((Including this information has the side-effect of revealing how much traffic this page gets.))</p> <h1>[nextprime]</h1> <p>You can also <a href="http://sigma-crow-364.appspot.com/" title="Prime Number Web App" target="_blank">visit the app itself</a> and read about querying the service to get prime numbers for your own web page!</p> <p>Learning Go and writing for the Google App Engine has been really fun. I’m ready for a new challenge! If you have a web application in mind, <a href="http://arnesonium.com/contact/" title="Contact">contact me and let’s figure out how to build it</a>!</p>
