Microsoft Cognitive Services Emotion API First Impressions

I am always interested and looking for new libraries to put to use in Xamarin.Forms. I recently stumbled upon Microsoft Cognitive Services Emotion API and wanted to see what it was all about. After a quick look at some sample code, I knew I needed to sign up and try this library out for myself.

The sample code I had been looking at can be found here Xamarin.Forms Emotion API sample code. The sample has some other services built into it but what really interested me the most was the Emotion API.

According to comments in the code, which I am always skeptical of, the API can detect happiness, sadness, anger, fear, contempt, disgust, and neutral. It is amazing that it can determine these emotions and with great accuracy. What is even more amazing is that it basically is one line of code.

This one simple line gets the first (highest percentile) emotion recognized from a picture. Using the sample code you can easily take a beautiful selfie, send it with the single API call, and within seconds get an emotion back. I am not sure yet what factors cause it to take longer but sometimes I get results back in under a second.

From my dozen or so attempts at taking a picture of myself, it gave quite accurate results. I have yet to fake fear in a picture but will see if I can one to happen.  I am very impressed with the Emotion API’s ability to analyze and image and produce an emotion result. Looking forward to Microsoft adding even more emotions.

The free tier for using the API is quite impressive in terms of the number of calls available. I hope to be writing a post soon showing off an app I have made in Xamarin.Forms incorporating the emotion API.

What is going right: Mob Programming Benefits (Part 2)

I have been in the mob for over a year and have more aspects of mob programming that I would like to share. Let’s jump right into What is going right: Mob Programming Benefits (Part 2).

  1. Idea Generation & Development
  2. Efficient use of time

Idea Generation & Development

Mob programming promotes the generation and development of ideas. You have multiple team members to bounce your ideas off of in order to come up the best solution. You do not need to come up with entire solutions on your own or have a fully thought out idea.

I have found myself presenting a half-baked idea, knowing that with the help of my team members we can work the idea into something real. It is a great feeling to be able to present just half of an idea and get input from the team on how to build it out to fruition.

This also helps in the opposite direction. If I present an idea not fully thought out and a team member can point out the flaws; I do not have to waste any more time trying to build the idea when in the end it would not even work anyway.

It is hard trying to take an abstract concept in your head and code it up into a full solution all on your own. But with mob programming, you have the help of your team the whole way.

Efficient Use of Time

Mob programming makes efficient use of the developers time. My mob only has one, yes ONE, regularly scheduled meeting a week. And even better only one mob member has to attend so the three of us on my mob rotate. I go to one regularly scheduled meeting every 3 weeks.

The rest of my time is spent coding. If my mob decides we should discuss a topic more in depth before jumping into code we do not schedule a meeting and find a conference room away from our computer to discuss.  We simply swivel our chairs to the whiteboard or just start talking.

On a good mob, impromptu discussion just happens when it needs to. If the code is flowing fast then no need to discuss, if we are up against a challenge start discussing.

Mob programming lets you focus on the code, which is exactly what every developer wants to do!
