ROS: Robot Operating System.

I had been aware of it in the periphery, but never “dug in” till this year. This was the year I helped to lead an autonomy competition at work, where using ROS was a key component.

Finally have st least a first order approximation of its strengths and weaknesses.

* A script that will quantise all any type image at any level of given directory.(like tiny png but for all formats including Gif). This saved a lot of space on my builds

* Made AI for my game sineline using rule based expert systems

* A remote file sync engine and CD software which deploys projects to digital ocean and configures clusters and stuff

* Made a GANS script that generates fictional art work based on other samples

Vue.js. I use it exclusively for front end now and have ditched Angular 2/React all together. I even got it approved for use in the very large enterprise I work at (internal apps only of course, but we have a lot of those). I also embraced messaging for good and was shocked at how easy NServiceBus makes everything regarding AMPQ. I continued to celebrate .NET Core advancements and use it for all my server side progra…

Why internal apps only?

How do you feel about the productivity for web development in Rust?

My priorities are unique to my situation, so a responsible answer to your question is "it depends on what you're trying to do". I am trying to create a scalable platform. Without having best practices to learn from, I had to discover what that required while trying to make the most of Rust. The discovery process involves many iterations of trying approaches out until a decent one emerges. On the other hand, once I la…

> Evidently, the costs associated with using an orm are greater than the benefits for someone who is fluent in SQL.

I largely agree although I've recently discovered the beauty of re-usable, type-checked sub-clauses by composing C# lambda expressions for Entity Framework using e.g., AndAlso():

C++ to the point to gasp and understand some of the standard lib implementation and the nitty-gritty details of move semantics and template meta-programming (thanks to haskell), yet the language never stops to amaze me, every large C++ project has completely different dialect (i.e. llvm/chromium/doom/v8/envoy), and they all are different kind of demons from hell yet I love the language. Haskell and Category Theory, b…

Didn't understand one part... How come the architecture skills only apply to banks?

I meant, to improve my software architecture skills using micro-services to modernize systems in financial institutions.

while i have learned smalltalk already a few years ago, it was only a short time ago that i found a smalltalk application that is so useful that it's worth it to keep a pharo smalltalk environment running at all times.

as a result i became easy to use that to build a small gui app to help me solve some issues.

the key takeaway is this: i have wanted to learn more about smalltalk ever since i started learning it, and i experimented with a few apps. but the effort of having to start a smalltalk environment every time i had a few minutes to dabble around just seemed like not worth the trouble. (it was like an 'out of sight, out of mind' thing, and it always seemed a bit to much to get used to how smalltalk works just for experimenting.)

but now that the environment is always running, and needs to run for that one vital application i am using, for which it is worth it to keep the smalltalk image uptodate and current, that makes it easy to spend free minutes to dabble around and try things.

I started learning Haskell again this year. And I finally got to work with it professionally. I'm also using PureScript in the same project, so it's really exciting. This year I also discovered R. I had to do a Python to R translation, so I got fairly familiar with R. I also discovered a few languages, but I haven't started learning them yet: red-lang and Pharo.

i started pharo a few years ago and finally found a killer app to make it worth the investment for me.

red-lang is on my list to learn for quite some time now, but it probably won't happen until i find a useful application in red that i can use.

same goes for haskell
