THaNks for the nice write-up."In the process I started automating my Electrical Engineering job in python" Care to explain more. I am an EE aswell and could some inspirations and ideas to Automate the boring stuff.

Thanks for the kind words, and I got a bunch of inspiration from Automate The Boring Stuff as well. I'll run down the list of automation I did, hopefully to give you some ideas. Least complex, to complex. >Kill program, launch program, and press OK. We have a program that crashes often. This quickly kills it(which otherwise requires clicking out of error messages). Then reopens and clicks OK which starts a long boot…

This is a very nice niche use of the various ideas discussed in that book. Perhaps you could write your own book that could outline some of these techniques and sell it into a niche. Know a few Mechanical engineers who have a general aversion to anything programming and they would lap itup. Just a thought.

None. There was no need to. Focus your energy on actually making more money and growing your business using tools you already know and are most comfortable with. Improving marketing and sales is more important than chasing after the next best tech stack.

How to improve marketing and sales?

Unfortunately Visual Basic because we still have it kicking around at my new job.

More fortunately, linq. It’s the thing I miss most when I’m not using the .net platform.

This year was quite fruitful. I started off dabbling a bit with basic Neural Networks. Nothing stuck in my mind until I did a mini project. In 2019 I plan to expand my knowledge to cover more algorithms and try some ML engineering tools such as MLFlow or Sagemaker. Next I learnt some Big Data technologies (Hadoop, Hive and Spark) due to job requirements. This is an ongoing process compared to Machine learning which was just a curiosity. Finally I learnt quite a bit of Ansible and little of Jenkins, once again for job requirement. While these are the major bits, I toyed around with few other tools such as OR-tools (operations research), Pandas, Matplotlib, Scrapy. On the whole, 2018 is a year I would like to replicate every year in terms of personal development.

Weirdly, perl. I found myself on a client site in a locked down environment with only the Windows version of GIT installed. Powershell disabled, no other programs allowed. I had to produce reports on the log files for this machine, but had to obfuscate information before taking it off the server. I discovered that git had bash installed quite early on, so my initial automation and reporting was based on UNIX pipeline…

In this day and age, with Python and all, is Perl still worth learning?

Spent some time really doing a deep dive into Zircon. Then also the RISC-V ISA.

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.

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?

In 2017, I was a copy editor and epidemiologist, but in 2018 I got a great full time opportunity to learn SQL and R on the job for a hospital. I've used these skills in real analyses of social work and food shortage amongst Veterans. In 2019, I hope to gain a deeper understanding of these two technologies and to add Linux and Python beginning skills to my knowledge. I also want to understand epidemiological theory, s…

I, too, am interested in this dataset.

Python and specifically Pandas via Juypter Notebook. As a business guy looking to use it more instead of excel, Tableau in 2019.

You should also consider learning R. Anything you can do in Pandas can be done, with less difficulty or fuss, in R. Plus, the plotting is much, much better.
