Python - I was a little hesitant because I really wanted to get more into Node/JavaScript but that’s what my team uses for simple scripts. Historically,I didn’t like any scripting language but I actually like Python for simple AWS backend lambdas and automation. AWS - At the beginning of the year I knew nothing about AWS. I thought it was just a way to host VMs. Since then I’ve done projects involving networking, Dev…

Have you found the certifications useful?

I learned a lot more about op amps, mosfets, SMD technology, bootloaders and PIC microcontrollers. These are fundamentals, so it's an investment with a high return value, I think.

Just curious. Is it just for your hobby or job?

Also for job.

Learned ReasonML and Solidity in 2018.

ReasonML is pretty great, though I think the syntax is much noisier than it needs to be, compared to Elm and OCaml. Documentation needs to be consolidated though, and the linter picks bad defaults.

Solidity feels like a language designed like someone that never learned lessons from having tried a lot of different languages. It feels much like a leaky abstraction over the EVM. Other than when doing embedded programming, this is the only language where I had to reason about what the compiler or VM was doing.

Don't know that I found a favorite tech this year.

Real World Embedded Systems. Built a dishwasher that cleans and sets your dinner table. C++, Arduino, Electrical Engineering, and worked with a mechanical engineer on the design execution. Here is the story, skip to the bottom if you want to see the youtube video- Started this year working on a finance App, this one needed to be perfect. React Native, Laravel PHP mysql. The app is almost finished, and is worthy of a…

This is so inspiring. It is also really amazing that you were able to do it in 2 months. How much time did you spend working on this? All the best!

Hardware.

I started 3d printing a ring with an embedded (existing) chip for 2FA.

Next I played with Rpi, usual tutorials with buttons + led. I picked up Android Things, and started building a led matrix controller.

However Android Things was too slow to directly control the matrix, thus I started playing with a STM micro controller (blue pill).

In parallel, I started working on Solo keys (https://solokeys.com), where I didn't build the hardware myself, but all the experience I gain was very helpful to keep up.

Next year will likely be more Rust and porting Solo to different platform, for example Arduino. Maybe I'll try to make my first schematic and manufacture it, we'll see how it goes (I have access to a good teacher :).

I discovered an interest in DevOps recently, so I worked on a few side projects using AWS. When it comes to languages or frameworks:

  - nodejs (express) coupled with ECS for deployments
  - vuejs for a small project
  - a tiny bit of Go
A few weeks ago, started a new project with Flutter and I have to say I am pretty convinced so far:

  - great tooling
  - easy to setup
  - close enough to react when it comes to principles
  - but a bit too verbose for my taste.
I also have my Arduino starter kit unopened on my desk.
