Learning to code

The more programming languages I learn the more it resembles human language for me. It takes a lot of practice to write content that humans want to read. It takes similar practice to write code that computers want to execute.

If I start writing in another language the meaning of the words might be the same, but how they will be interpreted by the readers could be completely different.

Even if you’re not using AWS this post shows how software problems are being solved with infrastructure. I especially liked “in the 2000s you were a ruby developer. In 2010s you were a rails developer. In 2020s you’re an AWS developer.” It used to be that infrastructure was an implementation detail—in some cases it still is. Now the language and framework is implementation detail.

There are a few different options for programming but less for terminals. I’ve used tmate in the past but it has limitations as a tmux fork. I found upterm this week and really like it. It’s open source and you can run your own proxy server which helps with security.

I have written a lot of bash, but it’s always difficult to start from scratch. This is a great first template if you’re going to write any complex bash.

I almost always prototype things in bash unless I hit one of these limits

The script is more than 100 lines
I need more than 2 arguments
I have to use an associative array

This template has a default amount of 4 arguments, but it’s still a helpful starting point.
