We use code formatter all day long. But what is the process of implement such as a tool?

In this post I will walk you through the journey of buliding a search engine from scratch using Python. As usual, all the code I’ve written can be found on my GitHub (microsearch repo). This implementation doesn’t pretend to be a production-ready search engine, just a usable toy example showing how a search engine works under the hood.

I recently implemented a small program to visualize the inner workings of a scheme that compresses floating point timeseries by XORing subsequent values. The resulting visualizations are quite neat and made it much easier for me to understand this beautiful algorithm than any of the explanations that I had previously encountered.

Render.com staging pipeline got blocked due to what looked like a simple query

SELECT e.id FROM events e JOIN postgres_dbs db ON (e.data ->> ‘serviceId’) = db.database_id LIMIT 1;

Can you spot what’s wrong? Let’s read

I’ll explain how to set up PostgreSQL for tests and discuss some common pitfalls to avoid.

Love it or hate it. We will stick with JavaScript for quite a long time. Understanding these objects and its memory lay out is a must to improve your performance optimization skill

One of feature of Mac is it can detect the right app to open a file, even without a file extension. How did it works and how it evolve

Lets learn how to re-create a service similar to ngrok by re-using existing software such as nginx and openssh. There is also a great repository for these tunneling softwares
