Planned work includes driver mapping, driver state controls, deeper USB and Bluetooth inspection, hardware-tree report export, and a bug-tracker shortcut. ### Source excerpt Introduction Hello! My name is Leo Rouleau, a first-year software engineering student at Polytechnique Montréal. I chose to apply for Haiku because of my interest in lower-level programming and operating systems. Having worked on projects involving microcontrollers and custom interpreters in C, C++, and Java, I've found systems-level development to be the most engaging challenge. Project Overview Haiku's current Devices application provides a basic list of connected hardware, but it lacks the features necessary to function as a true management utility. This project aims to transform Devices into a full-fledged hardware manager, allowing users to view detailed technical specifications and perform administrative tasks directly from the GUI. Goals Driver mapping Display the active driver module name and its absolute path for the device (/dev). State management Implement a graphical toggle to block or blacklist drivers with warnings for system restarts USB and Bluetooth support Increase the application's ability to inspect dynamic buses. For example, USB devices will display deep interface descriptors and HID report formats, and Bluetooth would automatically be populated correctly within the tree. Compatibility Report Develop a serialization logic to export the system's hardware tree into a standardized report. Bug Tracker Create a shortcut to open the Haiku Trac bugtracker with a report containing the hardware specifications of a selected device. Conclusion This was a blog to introduce myself to the community and the project I will be taking on this summer for GSoC 2026.

HarmonyOS is based on an open source operating system (OpenHarmony) that started as an R&D project at Huawei in 2012. The operating system has been architected to support a wide array of small computing devices from microcontrollers to tablets. It is already used in several of Huawei's TVs, wearables and wireless router products. In 2024 a 'pure' version of the OS, without Android support, was released. This has been branded HarmonyOS Next. Several questions leap to mind: 1/ Does the world actually need a new OS? 2/ Why should we care about what Huawei is doing -- especially those of us outside China? 3/ Finally, what are the chances of success for a new OS? Let's look a little deeper into these topics and try to understand what's going on in this space. 1/ Does the world need a new OS? YES Let me explain why I have come to this conclusion. Computing needs have changed We have seen a steady growth of small form factor computing. We carry computing devices in our pockets, they are found in devices throughout our homes, they are part of our vehicles, they are in medical devices, and in countless industrial settings. Within this context, one could argue that phones are at the larger end of the spectrum when it comes to small computing devices. Single board computers and microcontrollers can be found in mechanical keyboards, security cameras, hand-held medical equipment, at the checkout in our shops etc. Going further, it's not a huge leap to see that the field of robotics is due to take off with the advent of AI for real time context-aware decision making. My first argument, therefore, is that an operating system specifically designed for small computing devices will have a valuable role to play. (Neither iOS nor Android were designed or have evolved to address this need.) Innovation and competition are good Several operating system innovati ## Wireless Connectivity Solutions for ESP32-P4 DevFeed: [Wireless Connectivity Solutions for ESP32-P4]() Original publisher: [Read original article]() Author: John Lee Published: 2024-09-20T00:00:00Z Content type: article Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32-P4](), [Espressif](), [Embedded Systems](), [SOC](), [Bluetooth](), [Internet of things](), [Wi-Fi](), [Ethernet]() Tags: [blog](), [bluetooth](), [connectivity](), [esp32](), [esp32-p4](), [espressif](), [ethernet](), [iot](), [microcontrollers](), [open-source](), [soc](), [wi-fi](), [wifi](), [wireless]() ### AI overview This article compares three connectivity solutions for the ESP32-P4, which lacks integrated wireless connectivity: ESP-AT, ESP-Hosted, and ESP-Extconn.
