It’s been two years since I left Microsoft, and they finally decided to cancel my free employee Azure account. It was fun while it lasted, but now I have to move my data to a regular paid account. I looked through the FAQs and contacted support for the easiest way to do this, and unfortunately there is no officially recommended solution for moving storage accounts between different subscriptions.
I found some Windows-only tools that may have done the job, but I wanted a solution that would run on any platform.
The Hadoop File System (HDFS) is a distributed and redundant file system that stores your data in chunks across multiple nodes. This allows for fault tolerant data storage (a node can die without the loss of data) as well as parallel data processing. If you want to store and analyze large amounts of data, Hadoop is a great option.
I recently read a great book called Data Analytics with Hadoop, and this post is based on what I learned there.
About a month ago, I got my Sift Science plugin added to the WordPress.org online store. To publish your plugin to the store, you’re required to use the SVN repository that they provide. Once you get that done correctly, users of WordPress can find and install your plugin through the built in store and they will also receive notifications whenever you publish a new version.
In this post, I describe how I manage releases of my Sift Science plugin.
A few weeks ago I learned an important lesson that I’d like to share: When building unit tests, never use a mock/stub unless it’s absolutely necessary. Let me explain with a little example.
Let’s say you’re working on a large project and you start developing Module A, which uses a MySQL database. To write a unit test for this module, you’re going to need to mock the MySQL queries. I have used sinon for this purpose and it’s worked great by the way.
When I first started developing the Sift Science for WooCommerce plugin last year, I needed interactive controls on the Orders page that displayed fraud scores and allowed the admin to flag fraudulent users. I didn’t want to reload the page every time the user took an action, so the obvious solution was to implement some client-side scripting and background Ajax calls to the server.
The goal was to add a new column to the Orders page that contained small icons that displayed the score and a couple of other icons for the user to click like so:
I am pleased to announce that the Sift Science plugin for WooCommerce is finally ready for beta testing! Lukas and I started this plugin over a year ago and have been working on it off and on as time permitted. But I’m happy to say that it’s now good enough for Beta testing.
Note: I work at Automattic on WooCommerce, but this is a personal side project. What is Sift Science for WooCommerce?
