1-billion row challenge (1brc) is a challenge to process a 12GB file containing 1-billion rows of text.
Each row is formatted as <stationName>;<temperature>\n, and the goal is to aggregate the min, max, and average of each station.
For Node.js, the repository for the challenge can be found here. We will go through the implementation for the baseline approach, understand how it works and work on improving it until we reach a ~30x speedup.
As web developers, using 3rd party resources is extremely common. We use 3rd
party JavaScripts all the time, either via npm, bundled into our code, or via
<script> tag (e.g.: Google Analytics, etc). Embedding 3rd party images/media
is also pretty common. Even linking to a 3rd-party site can have security
implications!
Let's go over some of the more common attack vectors when using 3rd party resources, what problems they may cause, and how to mitigate them.
You work in tech. You sit in front of a computer for at least 8 hours a day. Are you actively doing something to counteract the negative effects?
CSS transitions are great, but they aren't always sufficient for more complex animations. Imagine a situation where you want to reorder a list of items, how would you write the CSS transitions for it?
In mid-late 2020, I left what most people would consider a very cushy and stable job: a software engineer position at a big tech unicorn. It definitely was not an easy decision to make, but considering that I tend to overthink and worry about stuff, it was a decision that I was surprisingly very confident in.
This writing serves as a personal reflection and retrospective of my journey from the past couple of years, which hopefully might be of interest to some people.
In July, I built Tranquil, a very simple web-app that allows you to create your own mix of environmental sounds. I have always loved the sounds of nature such as the rain 🌧️ , the blowing wind 🎐 , the sound of waves hitting the shore 🏖️ , etc.
I thought the project would be super simple. I should probably be able to just
put some <audio> elements with loop="true" on them, right? Well, as it
turned out, it wasn't that straightforward.
I recently landed my first remote job as a software engineer! 🎉
The past few weeks, some of my friends reached out to ask about stuff like how I found the job, what I did during the process to land the job, etc. I feel like this is something that more people might be interested in, so I thought I would write about what I learned during the process, and hopefully it will help you too! You can think of this as a semi-tutorial on how to look for remote jobs.
CSS-in-JS has been around for quite a while now. There are some valid reasons both for and against them, but we are not going to talk about those.
I have always believed that writing our own, simple version of something will help a lot to understand how something works, so let's try writing one!
Welcome! This is the first blog post I am publishing here! 🎉
I rewrote my personal site and added a blog to it while doing it. I decided to write about some of my thoughts during the process for the first post.
