- Bash - the gold standard for shell scripting
- Python - general purpose object oriented language, easy to write, widely used but hard to maintain due to environment differences, language and library changes over time
- Golang - imperative compiled self-contained binaries, simple toolchain, smashes Python in portability, maintainability, build time etc.
- Perl - fast to write imperative code, stable, the gold standard for regex string processing, works everywhere and doesn't break every few years like Python
- Groovy - a better version of Java, with interactive REPL and some language construct conveniences. Hard to want to write in Java again after getting spoilt by Groovy
- Java - battle tested, but slower to develop in than the above languages
- Scala - was supposed to be the next Java but wasn't
- Kotlin - another next Java, we'll see
- Clojure - another JVM language
- R - old data analytics languages, matrices, awkward, but widely used and lots of libraries
- Expect - an extension of the Tcl language specialized in interactive text interface automation and keystroke control
- HTMX -
bigskysoftware/htmx -
power tools for HTML
Beware the "Hello World"... see this meme further down.
Excellent TCL language framework for automating systems which have no alternative but interactive timed text inputs.
Autoexpect - generates an expect script from an interactive session, tune from there
Expect has libraries in most languages.
For example, used Perl's Net::SSH::Expect library to test iDRAC and iLO controllers
in check_ssh_login.pl
Add this to the top of an expect script to debug output:

If you need to share code privately or publicly to ask for help, you'll need a Pastebin site, se the File Upload & Code Pastbin Sites doc.
Counts lines of code vs comments vs blanks.
Install on Mac:
brew install clocInstall on Debian / Ubuntu:
sudo apt install clocRun it against a directory of code to count the lines of code:

Script in DevOps-Bash-tools to count lines across all public original GitHub repos:
github_public_lines_of_code.shCounts lines of code and cocomo man effort estimate.
Install on Mac:
brew install sccLinux - not in Apt yet, so you'd need to install it the Golang way:
go install github.com/boyter/scc/v3@latestRun it against a directory of code to count the lines of code:

The importance of documentation:
Every one of you engineers has done this…
Don’t pretend you haven’t !!
Not any more 😭
How many times have you tech bros questioned your life choices?
Be honest now…
Watch out for that quality and not knowing WTF you're doing!
I suspect this is only when recruiters try programming... 😉
Hate PHP... but PHP paid for the Range Rover...
Or even your own code from a while ago if you haven't written it carefully and commented any fancy tricks (avoid using fancy tricks).
This is at best janitorial work.
The number of weekend mornings I’ve woken up and jumped straight on the computer for my girlfriend to ask what I’m doing, and then I have to explain I’ve been stuck in a coding loop half the night and need to write this sh*t down to get rid of it...
The loyalty of a cat watching you get axed murdered...
Given the average tenure in Tech is ~18 months... you think you have time to train guys up?
This is why companies hunt for seniors instead of saving money on juniors at the expense of 2-3 years of training them up to proficient level only for them to leave for another company to reap the benefits...
Aren't you lucky this isn't me...
Pull Request reviews are here to preven this...
Many of you will want to send this to your relatives:
When you’re thinking about how to improve that code you wrote last night… 😂
