## Overview

`topmem` is a shell script that shows memory usage aggregated by process name. Unlike `ps aux` which lists every individual process instance separately, `topmem` collapses multiple instances of the same program (e.g. multiple `node` or `chrome` processes) and shows their combined memory footprint — making it easy to answer "which application is usin

Here are five distinct iterations of the Chicano tattoo-style theme, each expanding the narrative and scenery while maintaining the fineline black-and-grey aesthetic on vintage parchment.

### 1. The Boulevard Cruise
This scene shifts focus to a late-night cruise down Whittier Boulevard. The **Chevrolet lowrider** is depicted in motion, its front end hopped high in a "three-wheel motion" stance, captured with dynamic motion lines and blurred stippling. The **two skeleton figures** are seated

Explique-moi d’abord le problème que cette technologie résout, 

Puis les concepts clés, puis un exemple simple, puis un cas réel professionnel. 

Pose-moi des questions pour vérifier ma compréhension.
