NOTE-TAKING

Obsidian makes connecting ideas easy and helps you think and write better

Obsidian’s multi-pane editor and graph view

Obsidian might be the note-taking app we’ve been waiting for.

It wants to be your second brain. It lets you capture your ideas and take notes in text (Markdown) files (also check out this collaboration app that has built-in Markdown team wiki), and most importantly, it easily connects your notes and visualizes connections among them. It’s perfect for discovering insights from your notes. It’s also free, so you have little to lose if you try it. And if you use Alfred on macOS, check out my Alfred Obsidian workflow.

It’s made me rethink why we take notes and completely changed…


Collaborative apps like AirSend, Notion, and Jira help you implement Kanban

Kanban — process-oriented project management system

Prevailing wisdom suggests that the best way to succeed is to set specific and actionable goals. But decades of research and evidence from all walks of life have shown otherwise.

Both winners and losers have the same goals (e.g., launch a new app, win a race, write a book), so setting goals surely is not enough.

Whether you are an engineering or product team, athlete, artist, or knowledge worker, the process is much more important than the goals you set.

Process and system matter more than goals

Toyota’s success can be attributed to its focus on Kaizen (Japanese: 改善) or the process of continuous improvement, which is…

Note-taking

No, retaining shouldn’t be the goal of note-taking.

Zettelkasten note-taking. How to take notes.

Have you ever asked yourself what’s the point of taking notes? If you think it’s to remember, read on, because it’s a common misconception.

Like many things in life, taking notes has become so customary and ingrained in our routines that we’ve stopped reflecting on why we do so.

It’s surprising how little time we spend thinking about why we take notes, when developers regularly create new apps that aim to improve how we take notes. If you’re interested in the how, check out my post below:

Knowing why we’re doing something often provides insights into how we should do…

Note-taking strategies

Why do we take notes? How should we take notes?

I’ve been thinking quite a lot about note-taking lately. I debated with friends, did some research, and this post summarizes what I’ve learned about the second question: How should we take notes? (See also my post on how to learn.)

If you’re interested in why we take notes, check out my post below:

Below, I’ll describe how an app, Obsidian, a sociologist, neuroscience, and artificial intelligence (AI) have changed the way I think about note-taking.

The only function and tutorial you’ll ever need

R melt() to reshape dataframes from wide to long

How do you reshape a dataframe from wide to long form in R? How does the melt() function reshape dataframes in R? This tutorial will walk you through reshaping dataframes using the melt function in R.

If you’re reshaping dataframes or arrays in Python, check out my tutorials below.

Why melt but not other functions?

Common terms for this wide-to-long transformation are melt, pivot-long, unpivot, gather, stack, and reshape. Many functions have been written to convert data from wide to long form, melt() from the data.table library is the best. See melt() documentation here. Why?

  • Python’s pandas library also has the equivalent melt function/method that works…


LEARNING AND LIFE LESSONS

Journey from Vim noob to amateur

Vim joke and meme

What is Vim?

Vim stands for Visual Improved, an editor originally created for Unix.

Why Use Vim?

It’s powerful.

You can make complex edits very quickly. Check out my surround.vim post to get a sense of its power.

It’s ergonomic.

If you know how to touch-type, using Vim means you can keep your hands on the home row keys and not have to constantly move your hands to the arrow keys, trackpad, or mouse.

It’s everywhere.

It’s installed on almost every system, whereas other editors like Emacs and Nano might not be available. It’s cross-platform (works with Windows, macOS, and Linux). The default editor in most systems is Vim, so it’s useful…


Deliberate practice and surround.vim made me love Vim

vim and surround.vim increase productivity

I recently started learning Vim and it was difficult, especially during the first few days — my productivity took a real hit. I could barely write any code in Visual Studio Code without feeling a pain in my head. To learn more about my 15-day journey, check out this post:

Now, two weeks later, I feel quite comfortable using Vim and have fallen in love with it, thanks to lots of regular deliberate practice and Tim Pope’s surround.vim plugin. …


Ironic consequences of using willpower

Do you think you’re good at using willpower to resist temptations and distractions? If so, take on this willpower challenge while you continue reading: Do not think of a white bear.

Resisting Temptations and Distractions

We usually think of willpower as an ability that helps us inhibit and suppress thoughts, temptations, negative emotions, and distractions.

Given how frequently we’re tempted or distracted by events every day, it seems like willpower is key to productivity and a good life. (Also, check out Obsidian, a powerful and free note-taking app that will help you take better notes and increase your productivity and thinking).

But using willpower…


DIY & HUMOR

Make a reusable mask with just one sock and scissors

Face masks are becoming the new normal. Instead of buying disposable ones, you can easily make one yourself— with just a sock and a pair of scissors.

Remember, even if you wear one, remember to maintain social distance and avoid speaking when you’re around other people so you minimize the spread of fluids.

Homemade face masks don’t require a sewing machine or elastic (or rubber bands, string, cloth strips, or hair ties) to hook or tie the mask to your ears or head.
