eBPF 101: Your First Step into Kernel Programming

news.ycombinator.com Shrijith Venkatramana 2025-10-20 21:17:07

eBPF has revolutionized Linux observability and security by allowing sandboxed programs to run in the kernel without changing kernel source code or loading modules I. What is this eBPF? It looks scary! Have you wanted to write programs that act as drivers for Linux? Wanted programs to run at a kernel level? Wanted to monitor events, internal resources and get better observability? All you need to know is how to make good use of Linux eBPF. eBPF is a technology in the Linux kernel that can run

Object-oriented design patterns in C and kernel development

My scheduler operations implementation A benefit of working on your own operating system is that you’re free from the usual "restraints" of collaboration and real applications. That has always been a major factor in my interest in osdev.

You might soon be able to use Gemini Live on top of other apps (APK teardown)

Tushar Mehta / Android Authority TL;DR Google is testing more upgrades to Gemini Live’s floating interface before its launch. The upgrade now enables support for contextual cards within the floating interface. This will allow you to seamlessly switch between an app and Gemini Live seamlessly, thanks to a collapsible interface. Google Gemini is destined to fully replace Google Assistant on Android phones by the end of this year. Preparing for that transition, Google is continually upgrading t

UI vs. API. vs. UAI

First we built a user interface (UI) when the application was just going to be operated by humans. There’s a whole branch of study around good and bad patterns in that design practice, focusing on how we make things easily operable by humans. Then we added an application programmable interface (API) when we wanted the application to be operated by other applications - integrated programs. Similarly, there are whole conferences and books about what good design looks like for these interfaces, ai

More is less: I can’t make myself use Nothing’s Glyph Matrix

androidauthority.com Unknown 2025-12-09 17:30:59

Nothing’s original Glyph Interface was the perfect level of gimmick — it added a bit of flair to the back of its first few phones, but always felt like it had a purpose. I trusted it for everything from following the charge of my battery to watching for an incoming phone call, and it was one cool thing I could always show off to my iPhone-toting friends. Unfortunately, the Nothing Phone 3 took everything I loved about the original Glyph Interface and sent it back to the drawing board. It replac

Music lovers aren’t happy with Android Auto’s refreshed interface

Andy Walker / Android Authority TL;DR Google recently refreshed the Android Auto interface using Material You to match colors with your phone’s wallpaper. As part of the changes, the music player interface now uses wallpaper colors instead of album art and has smaller album art. Some users find the new design bland and unbalanced, compared to the previous dynamic album art backgrounds.

Hyrum's Law Put succinctly, the observation is this: With a sufficient number of users of an API, it does not matter what you promise in the contract: all observable behaviors of your system will be depended on by somebody. Over the past couple years of doing low-level infrastructure migrations in one of the most complex software systems on the planet, I’ve made some observations about the differences between an interface and its implementations.

Nothing Just Killed Its Phone's Flashy Glyph Interface. I Think the Replacement Is Better

Nothing just announced its long-awaited "first true flagship," the Nothing Phone 3, and killed off one of its most popular and unique phone features in the process. The flashing lights that crisscrossed the back of its previous phones, known as the Glyph Interface, is gone. In its place is something new -- a round black and white screen on the rear of the phone, adjacent to the cameras, which Nothing is calling the Glyph Matrix.

Writing a basic Linux device driver when you know nothing about Linux drivers
