Polychromatic Pixels
The article discusses the innovation in microLED technology by Q-Pixel Inc., which focuses on developing tuneable-wavelength microLEDs that eliminate the need for separate red, green, and blue sub-pixels. This new approach allows for ultra-high-resolution, cost-effective displays with enhanced brightness, energy efficiency, and longevity, overcoming traditional manufacturing challenges. Q-Pixel\'s advancements have achieved record-breaking pixel densities, indicating a significant shift towards the commercial viability and widespread adoption of microLED displays in various consumer electronics.
Devzat – Chat over SSH, with some nice quality-of-life features
Devzat is a custom SSH server that facilitates chat instead of a shell prompt, allowing users to connect from any device via SSH. Notable features include rooms, Markdown support, code syntax highlighting, direct messages, and built-in games like Tic Tac Toe and Hangman. Devzat can also integrate with Slack, Discord, and Twitter, and provides a plugin API for additional functionalities.
The Objects of Our Life (1983)
At the 1983 International Design Conference in Aspen, Steve Jobs spoke about the impending cultural revolution driven by personal computers, predicting they would one day become more prominent than automobiles. He emphasized the crucial role of design in shaping technology and asked the audience of designers to help ensure computers were made beautifully and intuitively. Despite the low number of personal computers in homes at the time, he believed their thoughtful design could significantly impact society and human experiences.
Hash-based bisect debugging in compilers and runtimes
Russ Cox describes **hash-based bisect debugging**, a technique that narrows down erroneous lines of code or call stacks in unfamiliar code bases by leveraging binary search concepts applied to program locations rather than version history. He explains its origins, implementation, and advantages using Go, contrasting it with traditional bisect methods, and highlights its effectiveness in debugging complicated changes like compiler optimizations and runtime libraries. The process involves hashing to ensure stable identification of critical locations and can be automated with tools like **bisect**, making complex debugging tasks significantly easier.
Evolving the ASF Brand
The Apache Software Foundation (ASF) is changing its corporate logo and branding to better represent its “community over code” ethos and ensure inclusivity, prompted by feedback highlighting the inappropriateness of their current use of Indigenous imagery. A new logo, which will replace the iconic feather, will be unveiled at the Community Over Code NA event in October 2024. The update includes providing new design resources for ASF projects using Indigenous imagery, while a legal name change is deemed impractical at this time due to extensive logistical challenges.
