Battlesnake: the Competition

A few years ago, I learned of a programming competition in British Columbia called Battlesnake. It had been covered in the media. Battlesnake and JRMPC share some common traits. First, they both involve creating a robotic “mind” (Battlesnake calls it an “AI snake”). Second, they both work off a grid and, at least in later rounds,Continue reading “Battlesnake: the Competition”

Smalltalk: An Entrepreneur’s Secret Weapon

If you’re an entrepreneur, and especially if you’re a digital entrepreneur, one of your greatest concerns is getting to market as quickly and as easily as you can. Your business is highly dependent on computers, whether that’s in the area of web applications or mobile development or machine learning or virtual reality or robotics or whatever. At theContinue reading “Smalltalk: An Entrepreneur’s Secret Weapon”

Fuzzy Thinking in Smalltalk

by Lorenzo Schiavina EDOR Metodi Quantitativi When I was a professor of Operation Research at the Faculty of Mathematics at the Catholic University of Brescia, I was lucky enough to contact Lofti Zadeh who was going to develop fuzzy logic and I was impressed by his work. Subsequently I deepened the topic by reading theContinue reading “Fuzzy Thinking in Smalltalk”

Extending the Smalltalk Syntax 4

by Leandro Caniglia President of FAST (Fundación Argentina de Smalltalk) Story 4: Hybrid Compilation Have you ever heard of the idea the creators of Smalltalk had for allowing any class to choose its compiler? To provide support for this classes respond to the #compiler message before the actual compilation is attempted. Why then, this capability hasn’t beenContinue reading “Extending the Smalltalk Syntax 4”

Extending the Smalltalk Syntax 3

by Leandro Caniglia President of FAST (Fundación Argentina de Smalltalk) Story 3: Tagged Nodes What do you do when you have to include JSON in a Smalltalk method? Something like this? In other words, do you represent JSON data with plain strings? Wouldn’t it be nice to improve this? What if the compiler knew that this StringContinue reading “Extending the Smalltalk Syntax 3”

Extending the Smalltalk Syntax 2

by Leandro Caniglia President of FAST (Fundación Argentina de Smalltalk) Story 2: Supporting Pragmas All Smalltalk dialects support pragmas. Here is one: However, not all of them support other types of pragmas, as Pharo does. So, let’s see what it would take to add support for them to our dialect. Where to start? Here is the roadmap:Continue reading “Extending the Smalltalk Syntax 2”

Extending the Smalltalk Syntax

by Leandro Caniglia President of FAST (Fundación Argentina de Smalltalk) Story 1: Adding Squeak Braces Does your dialect support Squeak Braces? To answer this question, try to evaluate the following expression: If you get an Array with the above two elements, today’s date and 7, it does. Otherwise, you would get a compilation error. In theContinue reading “Extending the Smalltalk Syntax”

A Look Ahead to Programming Languages in 2020

Python and JavaScript are the two hottest programming languages today. However, they cannot remain on top forever. Eventually, they must fall out of favour, as all languages do. This is likely to happen within the next decade or so. What languages might come to replace them? Here’s my list of challengers… Dart Thanks to theContinue reading “A Look Ahead to Programming Languages in 2020”

How is Smalltalk’s revival like the e-car’s revival?

It’s not a riddle. I’ll give you the answer. There are several interesting parallels between the evolution of the electric car and the evolution of Smalltalk. Let’s look at e-cars first. E-cars were pioneered in the 1830s. By 1900, they had reached their peak of popularity with a third of all cars manufactured in theContinue reading “How is Smalltalk’s revival like the e-car’s revival?”
