Apparently can be interpreted by the JavaScript engine as a block and not an object. That’s the first learning. The second learning is that the built-in object has an method that you can use for super simple and quick testing. The method signature is . Combine these two learnings and you have…

Boiled down to a sentence: it’s the choice of invoking a method based on whether something has the method, rather than based on whether something is of a certain type. Use duck typing when you care more about what something can do instead of what something is. For example, if you have a variable of…

Not knowing how to count up in binary is not a big deal. But it is nice to know the ground you're standing on as an application developer!

What is a cache? What is an example use case? Explained with a video

Food can be healthy and enjoyable. So should your friends.

Labeling posts by their maturity will help readers browse the digital garden with the right mindset, and so will you as you continue to create more posts.

This blog is run on Gatsby.js, a decision I made 1.5 years ago and haven’t looked back on. Well, until recently.

I started to use Instagram again, prompted by the entry of my daughter into my life. Before becoming active on IG this time, I had left the platform for a year and a half because I didn’t like the person I was becoming as I used it. Whenever I posted, I pegged too much of my self-worth to the…

About a week ago I sent out a letter to my subscribers asking them to tell me one question: Why are you subscribed? I wanted to find out what kind of people were on the receiving end of my nascent personal newsletter: What drew them to subscribe? What did they like so far from reading the newsletter…

Symbiosis comes from overlapping competitive advantage, true motivation, and impact for the businesses.

A nice & warm batch brew. Mmm… I realised something this morning when buying coffee at my local café — the person who pumped the batch brew coffee into my mug was not the barista, and she didn’t pre-heat my mug with hot water before pumping coffee into it. It didn’t bother me much; it was simply…

Two years already! I still love living in Berlin, a city of history and openness.

I have an apartment with a roof and plumbing and this is the bubble I have lived in for the last two weeks since my first child was born. A newborn bubble. I don’t sleep much and I don’t do very much other than feed, carry, coax, assist in burping, changing diapers, launder, cook, wash, eat, and…
