Unbundle #RustLang Watch Apps from #PineTime OS Firmware @PINE64 ... Now with clarity... https://gist.github.com/lupyuen/db39430c8a66ce7b4d803458b0daac06

Not really in a good place right now... So I'm sketching the design of Rusty Wrappers... That will unbundle #RustLang Watch Apps from the #PineTime OS Firmware @ThePine64... https://gist.github.com/lupyuen/db39430c8a66ce7b4d803458b0daac06

History of the #RustLang compiler...

#FIDO 2FA security keys generated by #RustLang and #TockOS on Nordic #nRF52840... Supported by Google! Hope to see TockOS on #PineTime someday...

What's new in #RustLang... "Relaxed Restrictions When Implementing Traits" looks useful for my projects...

https://blog.rust-lang.org/2020/01/30/Rust-1.41.0.html

...So why am I doing this? I used to teach Arduino / Embedded C... Which led to C pointer issues. For newbies it's best to start with a safer language like #RustLang... Save them the frustration of crashing pointers 😉 Now I'm creating Visual Rust to help newbies understand Rust syntax via drag-n-drop

Experimenting with App State for Visual @PineTime Apps @PINE64 ... Do YOU understand this Visual Program? 🤔 (Ignore the #RustLang code)

#RustLang for Jupyter Notebooks... By Google!

Particle Mesh died today... It's true, Mesh Networks are very hard to code! Anyone keen to join me in creating #RustLang Bindings for #BluetoothMesh Models? Maybe even a Domain-Specific Language? https://medium.com/@ly.lee/bluetooth-mesh-with-nrf52-and-apache-mynewt-44823407c471?source=friends_link&sk=ac433fa04e13f75985927c37db1e2b10

Story of my #IoT Life... Why I'm teaching IoT... And where I'm at now: Visual #RustLang on #PineTime @PINE64 https://medium.com/@ly.lee/my-5-year-iot-mission-5f2f28348780?source=friends_link&sk=8c9ab6f607d4b6af4a2b233e4096d623

#RustLang Ownership, Borrowing, and Lifetimes... What are they? Why do they made coding safer?

How #RustLang could have prevented the old Heartbleed SSL vulnerability...

Why are C Macros hard? Because they are a form of Metaprogramming. So are #RustLang Macros

What's #Metaprogramming? That's when you write a program that generates another program... Like here when I'm designing a graphical program (in Blockly) that will generate a #RustLang program for #PineTime Smart Watch @PINE64 ... https://developers.google.com/blockly/guides/overview

That's how I shape my Embedded code for #RustLang and C...
