Vim `:g` and :`v`

If you want to execute a command on all lines matching a pattern, you can use the Ex command :g. For example, if you want to delete all blank lines, you can do

:g/^\s*$/d

It will get all lines that matches this: from the beginning (^), it may contain 0 or more whitespace (\s*) until the end of line ($). In other words, if the line is empty or contain only whitespace.

Some Vim tips

I decided to compile a list of Vim tips as TIL (Today I learnt), although most of these tips I already knew. The following posts will follow a TIL format.

Zettelkasten

Do you struggle to learn different topics or keep different subjects in your head while you are working on some project? Well, me too. I have ADHD. I have multiple interests. When I hyperfocus on one of my interests, time flies. But usually, I need to learn different subjects and make them work together on a project. And I bet you need that, too. How can you solve it? One technique I use for studying different topics and making them work together is the Zettelkasten method. And you will learn how to leverage it to improve your learning.

Vim was a big part of my life

:e a-sad-email.md

I opened MacVim to tell a personal story.

The year was 1998, I was 15. I told my dad I wanted to go to a certification program. It’s something familiar in Brazil; you have high school courses and earn a certificate in parallel. I was inclined to study Chemistry (I really enjoyed the subject back then), but someone had suggested Informatics, and it looked promising. One problem: I didn’t have a computer and had no money to buy one. My dad said: “choose that one; we’ll figure it out.”

iPad Incompatibilities: Unintuitive Volume Buttons

The iPad is a useful tool. I have two, the ginormous 12.9” iPad Pro and an iPad mini, and I enjoy both. Each has its use case.

The Pro is used for consuming videos, photo editing, reading photography magazines and books, writing, and other activities that benefit from a large screen and, sometimes, a calibrated screen, such as when you enable the reference mode in settings.

The mini is used for quick consumption here and there. I occasionally watch videos on it, read books on Apple Books or even on the Kindle app, browse news, read my feeds, etc.

How to boost your creativity

A friend of mine shared with me two talks on different processes leading to creativity. A 2016 TEDx talk by futurist Stephan Schwartz and a 2019 TED talk by author Tim Harford. While Stephan Schwartz presents a process divided into six steps to induce creativity, Tim Harford shows a different method, much more diverse in approach. Comparing both processes, they seem conflicting; however, when analysing more closely, they complement each other.

Schwartz argues that by looking at the diaries of other creative genii from the past, such as Leonardo da Vinci, Michelangelo, Picasso, Einstein, Pauli, Planck, etc., to understand how they managed to produce so much stuff, we can distil it to a six-step process:

Opportunity Solution Tree

Have you ever tried to brainstorm ideas to find what to work on next? And you ended up with too many ideas that you had to aggressively trim down or, worse, you solved the wrong problem? Opportunity Solution Tree may help you avoid that.

Opportunity Solution Tree (let’s shorten it to OST) is a visual way to represent how the solutions connect to the desired outcome in a way that helps you focus on solving the right problem.

Extreme Ownership

When I first got a leadership role, I asked a friend for tips to learn and do my job better. He referred me to a book, Extreme Ownership, by Jocko Willink and Leif Babin.

The book’s main idea is to take ownership of everything you do (or don’t do), especially for a leader. If a team fails, the leader should step up and assume the failure instead of blaming the team.

Gear with soul

Does gear have a soul?

Recently I watched a YouTube video from Ted Vieira, a well-known photographer among the Fujifilm community, titled Gear With Soul? He shows a magazine by KEH Camera with the tagline “Gear with soul for people with vision” and spends the video showing photos and talking about that.

There’s also an old video from DigitalRev TV where Kai Wong discusses what makes a Leica M unique. And the very last line is “it got soul.”

Working through change

“It’s not the strongest of the species that survives, nor the most intelligent; it is the most adaptable to change.” This quote is often misattributed to Charles Darwin (it first appeared in a speech by Leon C. Megginson in 1963).

That quote refers to the evolution of the species, but we can bring it to the corporate environment, especially in the startup world. Companies pivot. Companies fail. Companies merge and get acquired—the culture of the company changes. For better or for worse, but it won’t stay the same. Some people can’t accept that. It’s ok to dislike the change and move to another company. People have different preferences and are suited to different environments. But if you’re resilient and can bear with the change, it can be an excellent opportunity to grow in your career.
