Prime Number Service on Google App Engine

2015-02-20T22:37:41+00:00

As I mentioned earlier this week, I’ve decided to learn the Go programming language. 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!

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 available on GitHub.

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.))

[nextprime]

You can also visit the app itself and read about querying the service to get prime numbers for your own web page!

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, contact me and let’s figure out how to build it!

Integrating Cedexis Radar with WordPress Sites

2015-01-26T20:00:52+00:00

Cedexis Radar is a real user monitoring (RUM) system that collects millions of metrics every day. It’s used to measure the health of networks in order for Cedexis Openmix to make intelligent routing decisions for web service users.

I put together a simple plugin to add Cedexis Radar tracking codes to a WordPress website. I’m not yet sure how much of an overlap there is between WordPress users and Cedexis Openmix users, but if you’re using both, check out my new plugin.

Sometime between 2015 and 2022, Cedexis was purchased by Citrix and no longer exists.

OpenPGP.js and WordPress

2014-12-03T16:14:51+00:00

Near the end of November, I began fiddling with OpenPGP.js and building a WordPress plugin. My goal is to create a method by which visitors can encrypt messages to me on my Contact page using my public key.

I finished up a pretty simple little plugin. You can view the details here or head straight to the GitHub project page.

However, when I finished earlier this week and decided to submit it to the WordPress Plugin Directory, I found that somebody had beat me to it by almost a month. I’ve taken a look at the code and it looks pretty good. You can check out my plugin, which was published as OpenPGP Form Encryption for Wordpress, and you can check out the other guy’s plugin, PGP Contact plugin.
