Transform Your Raspberry Pi 5 Into Miniature Desktop Gaming Rig With These Tower Cases

by: Abhishek Prakash Sat, 07 Jun 2025 15:36:14 GMT The bare Raspberry Pi board has a different appeal but I prefer keeping my Pis under cover, in protective cases. Now, there are tons of interesting cases available. You can also build your own with a 3D printer. The official Raspberry Pi 5 case and other small box design cases are okay for protection and they don't cost much.

Using Tabbed Interface in Vim

by: Abhishek Prakash Fri, 06 Jun 2025 16:15:07 +0530 Think of Vim tabs like browser tabs for your code editor - each tab holds one or more windows, letting you organize multiple files into logical workspaces.

Exploring the CSS contrast-color() Function… a Second Time

by: Daniel Schwarz Thu, 05 Jun 2025 13:45:56 +0000 In many countries, web accessibility is a human right and the law, and there can be heavy fines for non-compliance.
