I live in two places: a terminal running Claude Code and Neovim. For months I bounced between them.

You just suddenly get told to slow down. I wanted a small number on my status bar that tells me, at a glance, how much of my budget I’v...
This is a POC using Scala + Springboot. It is a simple project to demonstrate the interoperability between Scala and Java. Here is the full implementation. Requirements Java 21 SBT 1.10.5 Scala 3.6.2 Challenge 1: Scala Collections over Java Collections Imagine that you want to avoid the use of Java Collections in your Scala codebase. There are many reasons for that, but one of the ...

The user cannot see what is happening behind the scenes, but in their perspective looks like something that pop up in the screen without manual intervention. We call this behavior as async notification mecha...
