AI is an intelligence multiplier, in the same way that industrial machines are muscle multipliers. As our AI gets better, it will allow people to do more, faster, and better, in just about every field of work. Though the development of new AI methods remains the province of highly trained researchers, all of us are already interacting with AI daily, and so it’s important for everyone, and es...

The overall theme of Snap! development in the past year has been to foster "togetherness", such as:

  • SLOP (Several Learners One Project): Identify meaningful units of exchange and support packaging and sharing them, such as sprites, media resources, blocks libraries, single scripts, single custom block definitions. New feature: Bundle dependencies together with the ...

What do you think about, when you think of AI? I am sure that Wall-E, R2D2 and maybe Ava from the movie Ex Machina are among the thoughts that go through your head. Our associations with AI often go directly to imagining human-like robots. It is difficult for us to imagine that something can be intelligent without being or looking human. It is similar for learners. The easier we make it for ...

Block-based languages like Snap! have become mainstay tools for introducing programming to students of all ages.

This strong foundation is ideal for...

Snap! has the ability to make projects that define, train, and use neural network models. All that is necessary are list and arithmetic operations. But even with hyperblocks and the ability to compile blocks the programs will run several times slower than similar programs that use the Graphics Processor Unit (GPU).

Many existing approaches to bringing machine learning to blocks-based programming environments rely on embedded JavaScript or external APIs for the underlying model.
