A simple explanation and implementation of gradient descent — Let’s say we have a fictional dataset of pairs of variables, a mother and her daughter’s heights:

Event loop clearly explained — Profiling is commonly associated with performance optimization, but its applications extend far beyond that. For example, I had previously written on how profiling data can help estimate latency impact of infrastructure downsizing. Increasingly, one of the things I’m starting to appreciate more about profiling is that it can help you…

I think the Homer hiding gif best captures my immediate reaction when I saw the Memory tab for the first time.

Save money with limited performance impact — Profiling is first and foremost associated with performance optimization. However, another use case of profiling could be cost saving. This is something we’ve been exploring at work recently. Let’s say you have a backend service for some API endpoints. You allocate some number of CPU cores to this service. 3…

Flame Charts and Flame Graphs clearly explained — Flame charts and Flame graphs are both techniques of visualizing profiling data. For many software engineers, they are the first visualizations we encounter when we first start doing performance work. If you’re a frontend engineer like myself, chances are the Flame chart is what you are most familiar with. Although…

There are two principles in software development: Efficiency and performance are increasingly important parts of software development. It’s on the software, or more specifically, the makers of the software, to create an intuitive experience. In other words, it is NOT on the users to guess what the software wants them…

Here’s the much better advice instead — I have a confession to make. I don’t have an innate passion for writing technical blog posts. I started writing them as a way of solidifying my own learning. You know the saying: if you can’t explain something, you don’t understand it. …

When I reached my late twenties, my Instagram feed started to flood with new parents my age who looked like they aged an entire decade soon after their baby was born. They say parents make so many sacrifices for their children — that when you have a baby, your whole…

What makes you happy? For many of us, it’s not a simple question to answer. In my twenties, I’ve often found myself doing things I enjoyed but regretted later. I’ve also often found myself feeling happy in retrospect about things I did not enjoy in the moment. …
