Back in June, I started porting my dotfiles from ZSH to Fish. Here’s why. Initial performance Fish’s performance is a lot better than ZSH’s, and very similar to Bash. We can verify that by firing up a container with limited CPU and memory, like so: docker run --...
We live in the world where there are so many offerings of information in all possible formats: podcasts, videos, blogs, etc. But reading a good book is something that you’ll never regret.
Introduction I prefer to use relational (SQL) databases in general since they provide several features that are very useful when working with data. SQLite is a great choice since the database is a single file, which makes it easier to share data. Even though it’s a single f...

Sometimes, what's considered bad practice may make sense.

In the previous articles, we introduced techniques like DDD Lite, CQRS, and Clean (Hexagonal) Architecture. Even if using them alone is beneficial, they work the best together. Like Power Rangers. Unfortunately, it is not easy to use them together in a real project. In this artic...
Introduction Every single company I’ve worked at and talked to has the same problem without a single exception so far - poor data quality, especially tracking data. Either there’s incomplete data, missing tracking data, duplicative tracking data. - DJ Patil I spend a...
