Nothing. I can't remember if I switched our servers completely over to HTTP/2 and H2O server software this year or last. Otherwise, I believe there is nothing new under the sun and it's all just a different way of doing the same thing in an attempt to avoid fundamental software engineering for the masses.

By sticking to the fundamentals, we need nothing from anyone, our software runs everywhere on everything, and it's smaller and faster--and simpler--than everything else.

So this year I learned: Rust: While I'd dabbled in C++ before, it was mostly just a pain, while I found Rust to be a nicer way to work on lower level projects. Ported a game side project I've been working on from Python + Kivy to Rust + Piston, and came out with a nice performance boost. Mypy + SQLAlchemy: So while I have moved some projects from Python to Rust, others are still Python based and so I took the time to…

Is C/C++ knowledge important for learning Rust?

Opinions are split. Many people have learned it without any previous C or C++ knowledge. Some argue that you can't truly appreciate Rust until you've written them. It can be helpful, but it can also be harmful.

Not really. It'd help speed up the process for some areas, but it's not that significant as rust has other influences and its own unique areas.

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…

Is this an intelligent joke or a dumb business plan? I kept hearing the words "production" and "prototype", but I see half a dozen holes in a real world implementation. Edit: Since this is being downvoted, here are my thoughts. 1.) Plumbing. Pipes are in the walls. Kitchen tables are (usually) closer to the center of a room. (And who will consider open pipes or tubes across a floor or ceiling?). 1b.) Electrical. Same…

You strongly misunderstand the purpose of HN and the purpose of parent post.

This is not a product being sold. It's a neat fun gadget that was designed purely so parent robertAngst could learn stuff. The gadget is obviously a nonsense device, a Heath Robinson contraption, with no other purpose than to learn stuff while it's being built.

Learnt a lot of new things , learnt Elixir/Phoenix, now learning Nodejs with Hapi framework.

While learning Nodejs, realised that JS isn't the first language anyone should consider for back-end, but really amazed by things JS is capable of doing today.

Would highly recommend Elixir/ Phoenix over Rails , Elixir not only has lesser learning overhead it makes alot of things a lot easier. Concurrency and speed of server are major advantages but I like way language operates. It was also my first functional language and it changed my perspective for programming languages.

Machine Learning. In 2018 I went from "zero to sixty", so to speak. At the beginning of the year I knew nothing about ML, and my math skills had gotten so rusty I couldn't even remember how to do simple derivatives or multiply two matrices. In the first half of 2018 I relearned the college math that I had forgotten by working through MIT OCW's Linear Algebra, Calculus, and Probability courses. In the Fall, I enrolled…

That's amazing :) What do you plan on using ML knowledge? Like does having this skill have a market (for non-PhDs)?

Taught myself the basics of embedded systems, and completed a few projects. Learned circuit design, PCB layout, CAD / laser cutting, and embedded C / C++ in the process. Started with a 555 LED blinker [1]. Then built a desk clock, with a goal of writing a device driver for the LED display from the data sheet of a controller I found on DigiKey. After that, built my own USB keyboard, since I wanted to learn more about…

Great looking circuit boards!

Chris! I owe you big time for your getting started with KiCad youtube series. Your "Getting To Blinky" video is what gave me the confidence to get started with PCB design, so thank you! If you're ever in the Chicago area, I'd love to buy you a beer.
