How to create Drilldown graphs with R and highcharter

Hi. I’m Sharon Machlis at IDG Communications, here with Episode 51 of Do More With R: Create an interactive drilldown graph with R and the highcharter package.

Drilldowns can be a good way to present a lot of data in a digestible format. Here’s the example we’ll build today: Median home values by U.S. state; click a state to drill down to county-level data.

There are 3 main steps to making a highcharter drilldown graph:

1. Wrangle your data into the necessary format;
2. Create a basic top-level graph; and
3. Add the drilldown.
Let’s get started. If you want

Why we need more image masking tools to avoid facial recognition systems from identifying us online

For the past couple of weeks, a new tool to save your photos from facial recognition algorithms has been doing rounds. The tool, called Fawkes, is developed by researchers at the University of Chicago. 

The idea of the algorithm is simple: it uses image cloaking to modify a few pixels in your existing photo to ‘fool’ facial recognition systems. To the naked eye, these changes are generally hard to catch. That’s why if you see some of the photos below, you might not see any difference between normal and cloaked photos.

Cloud tech certifications count more than degrees now

Of the 10 major computing certifications that attract the largest salaries in North America, you might not be surprised that four are cloud related. The Google Cloud Platform Cloud Architect certification brings in real money, with certificate holders making an average annual salary of $152,129. AWS has three different certifications: Solutions Architect Associate, SysOps Administrator Associate, or Developer Associate. If you’re holding any of those certifications, you’ll likely make at least $130,000 a year depending on where you live.

If you think the economic downturn from COVID-19 has depressed some of the demand and salaries, you would be dead wrong.

Presenting the Azure Well-Architected Framework

Building and managing cloud services at scale is new to most of us; we’re either building our first tranche of cloud-native applications or have started to migrate existing applications from on-premises to the cloud. In many cases we haven’t had time to prototype and pilot. We’re being driven to rapidly take businesses digital by a global pandemic and a sudden shift to remote working.

The question then is: What are the best practices for working with hyperscale clouds such as Azure? What worked well in on-premises data centers may not be a good fit for virtual infrastructures or container-based microservice
