What's new in ArduinoJson 7
- Before we go into the good stuff, I must warn you that Arduino JSON 7 is significantly bigger than version 6. For example, on an Arduino Uno R3, the parser example is 41% bigger and the generator example is 45% bigger. Previously, all my design decisions were aimed at keeping the code small. Indeed, when I designed Arduino JSON 6, most users ran their programs on 8-bit microcontrollers. And that's why I focused so much on code size.

- Fixed memory allocation is perfect when resources are scarce but requires more discipline from the programmer. During the past five years, we attended to the rise of 32-bit microcontrollers, first with the ESP8266, then with the ESP32 and all the ARM-based MCUs. 32-bit microcontrollers have much more memory but also a bigger runtime framework, so Arduino JSON now represents a small fraction of the executable. If we compare the parser example on the two versions of the Arduino Uno, we see that Arduino JSON 7 makes up about two-thirds of the executable on R3 but only 7% on R4. Because the proportion is much smaller, the difference between Arduino JSON 6 and 7 is neglectable on 32-bit microcontrollers. For example, on Arduino Uno R4 minima, the parser example only grew by 2.3% and the generator example by 1.7%. As you can see, the size of the library is not so important anymore. Arduino JSON 7 can run on 8-bit microcontrollers but if the memory is tight, it's probably better if you stick with version 6.

- We just launched open source the sentence parser, Parsey McParseface.

- I think the important thing about the open source release we did of the parser is it's using TensorFlow as well.

Why Python is the language of AI: insights from Guido van Rossum (creator of Python)
- I wanted to redesign the parser completely using very different principles, a different sort of way of building parsers that was much more flexible for the syntax of the language.
