Running Wayland Clients as Non-Root Users on Yocto

news.ycombinator.com Burkhard Stubert 2025-12-17 03:30:27

Many embedded Linux systems use a Wayland compositor like Weston for window management. Qt applications act as Wayland clients. Weston composes the windows of the Qt applications into a single window and displays it on a screen. I still have to find a Yocto layer that does not start Qt applications as root. This violates the cybersecurity principle that every application should only run with the least privileges possible. Let us figure out how to run Qt applications as non-root users and make ou

For Iris Murdoch, morality is about love, not duties and rules

news.ycombinator.com Unknown 2025-12-15 08:12:08

Being in love is one of the most profound experiences we can have, one that can powerfully move us and irrevocably change the way we see ourselves, one another, and even the wider world. Literature and film often explore romantic love’s capacity to move us and radically alter our world (think of Romeo and Juliet, for instance), but this experience is not limited to romantic love: parents sometimes speak of experiencing overwhelming love at the first sight of their children, for example.

Pirate Library Operator Arrested, Study Canceled for 330K Members

A Lisp in 99LOC

news.ycombinator.com Unknown 2025-12-19 18:37:17

Lisp in 99 lines of C and how to write one yourself In honor of the contributions made by Church and McCarthy, I wrote this project and the accompanying article to show how anyone can write a tiny Lisp interpreter in a few lines of C or in any "C-like" programming language for that matter. I attempted to preserve the original meaning and flavor of Lisp as much as possible. As a result, the C code in this project is strongly Lisp-like in compact form. Despite being small, these tiny Lisp interpr

Dyna – Logic Programming for Machine Learning

news.ycombinator.com Unknown 2025-12-19 20:50:15

A Weighted, Declarative, Logic Programming Language Dyna About the Dyna Programming Language Dyna is a programming language designed by and for machine learning researchers. Dyna builds on the paradigm of logic programming languages such as Datalog and Prolog. However, Dyna goes much further in that it allows for flexible execution orders and for rules in the program to be "weighted". This means that we can efficiently express complicated programs in a few lines of code without having to worry

When The Rocky Horror Picture Show premiered in 1975, no one could have dreamed that it would become the longest-running theatrical release film in history. But that's what happened.

Toothpaste Made From Hair Works Better Than Fluoride, Scientists Say

Looking for an effective, sustainable toothpaste? It might be on top of your head. Scientists have discovered that keratin, a protein found in hair, skin, and wool, can repair tooth enamel and stop tooth decay. It might also protect teeth even better than conventional fluoride-based toothpastes, stopping tooth decay in its tracks, according to a new study. When keratin comes into contact with saliva, it forms a protective coating that mimics natural enamel, the study shows. Not only can it shi
