Writing: A Powerful Tool for Untangling Thoughts

2025-02-28

Our minds are like cluttered archives, struggling to organize information effectively. Writing acts as scaffolding, helping us build a clear framework for our thoughts. It forces us to untangle the chaos in our heads, piecing together scattered fragments into a coherent whole, revealing hidden biases and blind spots. Through writing, we can expand our mental horizons, expressing ideas more clearly and coherently than in face-to-face communication, offering even greater insight. Writing reveals the gaps in our understanding, helping us to understand ourselves and the world more deeply.

NASA's GUARDIAN System Uses GNSS Data to Enhance Tsunami Early Warning

NASA has developed GUARDIAN, a near real-time ionospheric monitoring software system that leverages Global Navigation Satellite System (GNSS) data from NASA's Jet Propulsion Laboratory's (JPL) Global Differential GPS (GDGPS) network to detect natural hazards. By analyzing ionospheric perturbations, GUARDIAN supplements existing early warning systems, particularly for tsunamis. Currently, it's the only system publicly providing multi-GNSS near real-time total electron content (TEC) time series data over the Pacific, significantly contributing to improved tsunami warning accuracy and timeliness.

Wild: A Blazing-Fast Linker for Linux

Wild is a linker designed for speed in iterative development. While incremental linking isn't yet implemented, it's already impressively fast. For production builds, more mature linkers like GNU ld or LLD are recommended. However, for development, Wild significantly speeds up build times, especially on x86-64 Linux systems. It supports statically and dynamically linked executables and shared objects, and has been tested with many popular crates from crates.io. Currently under development are features like incremental linking, support for other architectures, and more linker flags.

NixOS Build Reproducibility: Better Than You Think

2025-02-12

NixOS's build reproducibility has long been a point of contention. While its functional package manager model contributes to build reproducibility, it doesn't guarantee bitwise reproducibility for all builds. A new research paper empirically studies Nixpkgs (NixOS's package collection) over six years, revealing a steadily increasing reproducibility rate—from 69% in 2017 to 91% in April 2023. The study also identifies prevalent causes of non-reproducibility, such as embedded dates, uname outputs, environment variables, and build IDs. These findings demonstrate that while Nixpkgs already achieves high reproducibility rates, there's room for improvement by addressing these low-hanging fruits. This research is crucial for increasing trust in the Nix substitution protocol and driving the development of distributed caching solutions based on build reproducibility.

Online Job Applications: A Waste of Time?

After a pandemic-induced break, the author tried online job applications for the first time, only to be met with overwhelming disappointment. Nearly 1000 applications yielded almost no responses. This led him to conclude that online job platforms are largely ineffective, filled with scams and dead ends. He contrasts this with the far superior approach of networking, building a public profile, and directly contacting target companies. The author likens online applications to throwing a letter into the ocean; ultimately, he found his current job through his network.

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.

Hunting a Ghostly Embedded Bug: Error -22

The Tweede golf team encountered a frustrating bug in their embedded Rust software for the nRF9160 microcontroller, resulting in Error::NrfError(-22) when sending data to a server. After weeks of investigation, they traced the issue to the libmodem library's initialization function. A pointer to a stack-allocated configuration struct was used after the struct was destroyed, causing unintended writes to the shared memory region configuration and resulting in a data length of 0. Adding `black_box` and using watchpoints ultimately located and fixed the bug. The team highlighted the benefits of using Rust for embedded development to prevent such low-level errors.

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.

Infinity's Size: Mathematicians Get Closer to Answering How Many Real Numbers Exist

For decades, mathematicians believed determining the total number of real numbers was an unsolvable problem. A new proof suggests otherwise. The article details how mathematicians Asperó and Schindler proved that two axioms previously considered competing foundations for infinite mathematics actually imply each other. This finding strengthens the case against the continuum hypothesis and indicates an extra size of infinity exists between the two that, 143 years ago, were hypothesized to be the first and second infinitely large numbers. While this result has generated excitement and debate within the mathematical community, the arguments surrounding the sizes of infinite sets are far from settled.
