Last week, Ed Charbeneau interviewed me for his Eat Sleep Dev podcast. The topic was Cognitive Services – a technology I’m passionate about.

You can listen to that interview below.

Last week, I delivered a presentation on Angular 2 and TypeScript at the Northwest Chicago JavaScript meetup. The organizers recorded my presentation, which you can watch here or below.

Yesterday, I posted a list of community technical events in the US Central Region.

I thought this would be a useful reference to those who want to attend or speak at conferences. This is a living document as I learn about more conferences and as conferences announce their dates.

The problem with this post is that it is time-stamped and will farther and farther down the list of posts as the months pass. So I created a copy of this list and pinned it to the top of my site. You can reach this list at any time by clicking the “Tech Events” tab at the top of each page. Or you can just click here.

Here is a list of community technical events (conferences, code camps, etc.) in the US Central Region. I have listed the dates, if they are published. If no 2017 date is published, my estimate is based on last year’s date. I provided a link to each event’s home page so you can check the latest information directly from the source.

Please let me know if I am missing any.

LMB01Last week, Ladysmith Black Mambazo brought a bit of South Africa to Chicago. The vocal group performed at The Old Town School of Folk Music Saturday February 11.

LBM was formed by Joseph Shabalala in Ladysmith, South Africa in 1964. Shabalala did not make this trip, but a number of his sons still perform with the 8-man group. Westerners learned of their talents in the 1980s when they recorded the classic "Graceland" album with Paul Simon; but they have been touring and recording on their own for decades. Their tight harmonies and blend of African and western music make them appealing to audiences all over the world.

LBM delighted the audience in a too-short (about 80 minutes) performance before a sold-out theater. They blended harmonies and melodies and humor and Zulu dancing to entertain us. There were no instruments because there was no need for instruments.

LMB02They sang some songs in English and some in the Zulu language. "Homeless" and "Diamonds on the Souls of her Shoes" from "Graceland" were crowd pleasers; but most of the night consisted of traditional African songs and their own compositions. For most songs, a different member of the band would step to the front of the stage to sing lead, while the remaining 7 harmonized behind him. Some songs were accompanied by coordinated Zulu dances.

The night concluded with a stirring rendition of "Amazing Grace".

Ladysmith Black Mambazo has long been on my list of bands to see live. Now I can cross them off the Bucket List. Until the next time they come to town.

When I worked in consulting, part of my job was to interview potential new hires. This often included a technical screening. Here are a few of the questions I would ask on Object Oriented Programming (OOP)

What is the difference between an object and a class?

An object is an instance of a class. A class is a template - or blueprint - that describes what an object based on it will look like and behave. Further, objects have a defined lifetime - they are created and eventually destroyed; not so with classes.

What is encapsulation?

Encapsulation is an OOP principle describing an object hiding its implementation details form the outside world.

What is inheritance?

Inheritance describes a class that is derived from another class or from an interface. The derived class (or child class) inherits the properties and methods of the parent class or interface from which it is derived.

What is polymorphism?

Polymorphism describes to objects that can accept the same message (e.g., the same method call with the same parameters) and respond differently, but appropriately to that message. For example, a Customer class and an Invoice class may each have a "Print" method. Calling the Customer's print method could print a report listing details about the current customer, whereas calling the Invoice's Print method might print a specific invoice.  Polymorphism can be accomplished by implementing the same interface in multiple classes.

What is the difference between a Class and an Interface?

Although each can serve as a templates for inherited classes, an Interface includes only the names and signatures of properties and methods, whereas a class also includes the implantation of each method and property.
