Reclaiming Sensor Data: Breaking Free from the Cloud

This article details how an embedded software engineer regained control of data from a cloud-connected radon sensor by bypassing the manufacturer's servers. By analyzing network traffic, the engineer discovered a vulnerability where the sensor didn't properly validate server certificates. Leveraging a local DNS server and a custom Python web server, the engineer successfully intercepted and read the raw sensor data. This grants programmatic access and ensures continued functionality even if the manufacturer's servers go down. The article highlights the importance of network security and the privacy risks associated with DNS traffic.

The Secret Spy Satellite That Helped Win the Cold War

In the 1970s, the rise of the Soviet Navy posed a significant threat to the US. To counter the emergence of powerful new Soviet warships, the top-secret Parcae satellite program was launched. Developed by the US Naval Research Laboratory, Parcae provided real-time location data on Soviet vessels, drastically reducing the time between signal interception and intelligence reporting to mere minutes. This near-instantaneous intelligence was crucial for military decision-making. Employing multiple satellites working in concert and advanced computer systems to process massive amounts of data, Parcae helped maintain the strategic balance during the Cold War. Its technology continues to influence modern satellite signals intelligence systems.

Saying Goodbye to bcachefs: One User's Reluctant Migration

2025-01-23

After a year of using bcachefs, Steinar Gunderson has migrated to XFS. His reason? A lack of confidence in bcachefs' future. While appreciating its compression and mixed SSD/HDD capabilities, he found the developer's uncompromising attitude, hostility towards distributions like Debian, and numerous unfixed bugs (including catastrophic data loss) unbearable. Reporting bugs proved a frustrating experience, with the developer prioritizing arguments with Debian over bug fixes. He ultimately chose the stability of XFS, sacrificing compression benefits, a trade-off he deems worthwhile.

In Praise of the 100-Page Idea: A Case for Brevity in Nonfiction

2024-12-22

Tracy Durnell argues for the value of concise nonfiction books, specifically those around 100 pages long. She finds these shorter works ideal for exploring a single, impactful idea without excessive detail, fitting modern readers' shorter attention spans. Durnell highlights several examples of excellent books in this length, contrasting them with longer works that she believes often dilute their core ideas through padding. She champions the efficiency of a focused approach, emphasizing the benefits of connecting multiple concise ideas to build a broader understanding over consuming lengthy, highly-detailed tomes.

President Trump issued an executive order temporarily halting enforcement of the TikTok ban for 75 days. This move aims to prevent penalties against American companies like Apple and Google for working with TikTok, but its legal standing is questionable. The ban stemmed from a law demanding TikTok divest from its Chinese parent company, ByteDance, and Trump's action effectively circumvents this legislation. While the reprieve may offer temporary relief, the decision carries significant legal and political risks, with massive fines still a possibility and its effectiveness highly debated.

Tramway SDK: A Lightweight Game Engine Defying Turbobloat

2025-01-07

Tramway SDK is a lightweight game engine challenging the 'Turbobloat' of mainstream engines like Unity and Godot. Developed over three years, it aims to bring 3D game development to older hardware. Using software rasterization, it eschews the need for a graphics card and runs on 15-year-old hardware, lowering the barrier to entry and reducing e-waste. It ditches node-based systems in favor of entity class inheritance and streamlined coding. Optional editors and whitespace-separated value configuration files simplify the workflow. Tramway SDK also includes an RPG framework, supporting level streaming and Quake/Source style entity interaction for easy open-world RPG creation. While still early in development, its lightweight nature and ease of use hold immense potential.
