Firebase: The Good, the Bad, and the… Good Again?

|

First Contact We were building a small proof of concept for a mobile app, when one of the stakeholders requested that we evaluate Firebase for it. It was my first exposure to Firebase, which looks like it was a cloud database that grew to include authentication, notifications, and other features. On the face of it, it looks interesting — mobile devices could load and store data using the Firebase API, no back-end server or hosting needed. Different devices could get…

Angular updates – ng-conf 2017, new seed, cli updates, guides, Angular 4? and more…

|

It’s been a while since I’ve written about Angular (2 – drop that label, now it’s just Angular) as I’ve been consumed with teaching and developing courseware on a variety of subjects. But now I am coming up for air, just in time for ng-conf 2017. Three of us from Chariot will be there – me, Rich Freedman, who just posted this gem about Spring Security and Angular (2) (part 2 coming soon), and Dan Kyle, who will be manning…

That’s what happened to me with VectorDrawable. I heard about vector graphics by watching a Google video and immediately went to my project in Android Studio. I located to the res/ folder, right clicked and…

Scala By The Schuyllkill Recap

This past Tuesday I had the pleasure of attending the Scala by the Schuylkill conference at Comcast headquarters in downtown Philadelphia. Initially begun as an internal Scala conference, the organizers opened the conference this year to external folks interested in Scala. I learned a lot from this event, gaining perspective on trends in the Scala community and sparking curiosity in several interesting applications of the Scala language.

Saving Blood Pressure data to Apple's HealthKit

|

While working on one of our demo mobile apps for the upcoming SXSW conference, I found the need to store blood pressure and heart rate data in HealthKit. Apple’s documentation is pretty solid and has some good examples on how to use the HealthKit framework. In this short post, I’ll walk through the code snippets required to request access to write data to HealthKit and then actually write the data. The demo app I am working on interacts with a…

Tyk as an on-premise API Gateway

|

Recently we looked at API Gateway products for a microservices project. The constraints were that on-premise was preferred, low-cost was preferred, and open source would be fine. While we could have built something simple, the thought was that a product would have more in the way of management and monitoring features. We settled on Tyk for the time being. Here is a quick summary of our evaluation.
