"When messages are trusting and ask for what the sender wants instead of telling the receiver how to behave, objects naturally evolve public interfaces that are flexible and reusable in novel and unexpected ways." (Sandi Metz, "Practical Object-Oriented Design")

Tip for Linux shell beginners: Execute a second command only if the first one failed. `command_1 || command 2` Background: This compound command uses the result code returned by `command_1` with the "shortcircuit" behaviour of the "logical OR" `||` operator. #Linux #Shell #Terminal

One of the features for which I love Ruby is that it has syntax features that let me express clearly what the intention of my code is. - `unless` instead of `if not` - `until` instead of `while not` - `loop do` instead of `while true` #Ruby #Coding

Almost every Linux CLI tool that requires you to edit a file will consult the `EDITOR` environment variable to spawn the editor you prefer. If you want to use `nano` instead of `vim`, set it as your default editor like this: `export EDITOR=nano`

As someone who is less than 2 weeks from taking the oath of fidelity to the Irish nation and to 'respect its democratic values', I find this news incredibly disheartening. It is bad policy in search of a problem and a pathetic sop to a racist minority who do not embody the ideals of the nation.

A significant contributor to the gender pay gap and the continuing financial disparity between men and women is the undervaluing of all of the unpaid care work done by women in Ireland. Women all over Ireland get up early, every morning, and go to work, unpaid and unvalued.

The `find` command on Linux is as useful as its argument list is hard to construct. A refreshing alternative is `fd`. I can just type `fd PATTERN` instead of `find -iname '*PATTERN*`. And holy cow, is it fast! github.com/sharkdp/fd

In the recent podcast of The Pragmatic Engineer, Addy Osmani coined a great term for what led to my latest failure in agent- supported coding: "cognitive surrender". When you delegate work to agents, don't delegate the thinking as well.

Is it just me, or has GPT become more prone to overengineering lately? This is the third time in as many projects that I had to intervene because it was about to build safety features that were completely disproportionate to the small risk it was addressing.

Tabs vs spaces has always been a controversial topic. Thankfully, #vim isn't biased in any way. To convert spaces to tabs, use `:set noexpandtab`, then `:retab!`. Convert tabs to spaces with: :set expandtab :set tabstop=4 :set shiftwidth=4 :retab
