Developer writes custom Linux driver to get free over-the-air TV on Raspberry Pi

·1 views

A developer built a custom Linux kernel driver from scratch in May 2026 to make a MyGica A681 USB TV tuner work on a Raspberry Pi 5, after finding no compatible driver existed for the device. The tuner's manufacturer only provided a prebuilt driver for standard PC processors, leaving the hardware unusable on the Pi's different chip architecture. The developer leveraged existing open-source Linux TV community code for the tuning and decoding components, writing only the missing USB translator layer himself. An early debugging session revealed that a self-imposed configuration change — not a code flaw — was blocking video output, and restoring the original default immediately resolved the issue. The project ultimately enabled free, subscription-free over-the-air HD television on a kitchen-mounted smart home display.

Developer builds Play Store assets without Figma using free browser tool Resizo

A developer has shared how Resizo's Feature Graphic Maker, a free browser-based tool requiring no signup, can handle most Google Play Store and App Store asset creation tasks. The tool addresses a common pain point where design apps like Figma and Canva export PNGs with alpha channels, causing silent rejections on Google Play upload. Resizo structurally prevents this by always compositing an opaque background layer, ensuring exports meet Play Store's strict no-transparency requirement. Beyond the feature graphic, the tool supports dozens of canvas presets covering specific device screen resolutions for both Android and Apple devices, social media banners, and custom sizes up to 8000px. Switching between presets does not reset existing work, making it a practical alternative to traditional design workflows for app store submissions.

Developer Shares Practical Racket and Functional Programming Cheat Sheet

A developer published a comprehensive cheat sheet on Racket after exploring the Lisp-based language over a weekend. The guide covers core syntax rules, including prefix notation, parenthesis usage, and immutable global bindings created with define. It also explains conditional expressions, named and anonymous functions, and local variable scoping with let and let*. List operations are detailed using both traditional Lisp conventions like car and cdr and modern aliases such as first and rest. The cheat sheet concludes with higher-order functions including map, filter, foldl, and foldr, which replace traditional loops in functional programming.

How Python Generators Use Lazy Evaluation for Efficient, Memory-Friendly Code

A technical tutorial published on DEV Community explores advanced use of Python generators through the concept of lazy evaluation. Lazy evaluation delays the computation of an expression until its value is actually required, reducing memory usage and avoiding unnecessary processing. Python generators naturally support this approach by yielding values one at a time on demand, rather than producing all results upfront. The article also covers advanced techniques such as caching and memoization to further optimize generator-based code. These methods are presented as practical tools for developers seeking to write more scalable and performant Python programs.

How to Build a Python-Based Job Board Scraper for Remote Work Listings

A job board scraper is a web scraping tool designed to automatically extract remote job listings from platforms like We Work Remotely, Remote.co, and FlexJobs. Built using Python libraries such as Scrapy, Beautiful Soup, and Requests, the tool allows users to collect real-time job data and filter it by category, location, or other criteria. The scraper works by crawling job listing pages and pulling key details such as job title, company name, and location. Users can export the collected data to a CSV file for further review and analysis. The approach helps job seekers avoid duplicate listings, stay current with new postings, and streamline their remote job search.
