42: A Powerful Spacecraft Attitude Control System Simulator

42 is a comprehensive general-purpose simulation of spacecraft attitude and orbit dynamics, primarily used to support the design and validation of attitude control systems throughout their lifecycle, from concept studies to integration and test. It accurately models multi-body spacecraft attitude dynamics (rigid and/or flexible bodies), and both two-body and three-body orbital flight regimes, simulating environments from low Earth orbit to throughout the solar system. 42 simulates multiple spacecraft concurrently, facilitating studies of rendezvous, proximity operations, and precision formation flying. It also features spacecraft attitude visualization.

Former Tech CEO Sues Journalist for $25M Over Sealed Arrest Record

2025-01-26

Maury Blackman, a former tech CEO, is suing journalist Jack Poulson for $25 million after Poulson published details of Blackman's sealed 2021 domestic violence arrest. While a judge sealed the record, the information remains accessible online. Blackman argues the publication caused reputational harm and violated California law, while Poulson contends it served the public interest and is defended by the Electronic Frontier Foundation. The case highlights the conflict between freedom of the press and individual privacy, particularly concerning sealed records.

Serbia: A Digital Prison – State Surveillance and the Suppression of Civil Society

Amnesty International's report reveals Serbia's use of surveillance technology and digital repression to control and suppress civil society. The report details widespread use of spyware, including NSO Group's Pegasus and a newly disclosed domestically-produced Android spyware, NoviSpy, along with Cellebrite's UFED tools against environmental activists and protest leaders. This constitutes a serious human rights violation and attack on freedom of expression.

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.

Colorado Farm Marries Solar Power and Agriculture for a Sustainable Future

A Colorado farmer has pioneered a sustainable model by integrating solar panels with his farm. His 3,276 panels power roughly 300 homes, while the land beneath them supports various crops and livestock, offering crucial shade during Colorado's hot summers. This 'agrivoltaics' approach not only boosts income but also protects soil and improves land use efficiency, offering a blueprint for climate change adaptation. However, challenges remain, including higher initial costs, increased land management demands, and a lack of policy support for agrivoltaics.

Go 1.24's `go tool`: A Game Changer for Dependency Management

Go 1.24 introduces a revolutionary change in tool management with the new `go tool` command and the `tool` directive in `go.mod`. Previously, developers relied on `tools.go` or manual installations, leading to performance overhead and dependency bloat. `go tool` elegantly solves these issues. Its caching mechanism speeds up builds, and it prevents unnecessary dependencies, significantly improving developer workflow. While migration might encounter some compatibility hiccups, like with gqlgen, the performance gains and streamlined dependency management make `go tool` one of the most exciting advancements in the Go ecosystem in recent years.

Trump Halts TikTok Ban for 75 Days: A High-Stakes Gamble

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.

Attention as Electromagnetic Field Line Management: A New Model of Consciousness

Qualia Research Institute proposes a novel model of attention, conceptualizing it as the management of dynamic patterns in the brain's electromagnetic field. By simulating electric field lines arising from weighted sums of harmonic oscillations, researchers demonstrate how attention controls charge density by modulating underlying resonant modes, explaining seemingly random fluctuations and drifts in attentional behavior. This model also offers a potential explanation for psychedelic experiences, suggesting that psychedelics disrupt the normal flow of attention by altering the configuration of harmonic modes. The research provides a new lens for understanding consciousness and developing novel neuro-interventions, such as inducing exotic states of consciousness by non-invasively perturbing the phase locking of attention.

This article delves into the true motivations behind systemd, revealing how Red Hat leveraged its business interests in embedded devices to transform systemd from a simple init system into a core component of the Linux operating system. The author alleges that Red Hat used various tactics, including lobbying open-source projects to depend on systemd and poaching developers from other distributions, to exert control over the Linux ecosystem, sparking a backlash within the open-source community and leading to the resignation of several Debian developers. Systemd is described as a monolithic system with privacy concerns, and Red Hat's ambition is portrayed as creating the next Windows. The article concludes by advocating a return to community-driven development and recommending alternatives to systemd, such as runit and s6.
