EHT Reveals Turbulent Accretion Flow Around M87*'s Black Hole

2025-01-25

The Event Horizon Telescope (EHT) Collaboration has released a new analysis of the supermassive black hole at the center of Messier 87 (M87*), combining observations from 2017 and 2018. The study confirms that M87*'s black hole rotational axis points away from Earth and highlights the significant role of turbulence within the accretion disk in explaining the observed shift in the ring's brightness peak. Using a vastly expanded simulation image library, the team confirmed the counter-clockwise 30-degree shift of the brightest region of the ring between 2017 and 2018. This research represents a major step forward in understanding the complex dynamics of black hole environments.

Iron Age Society Centered on Women: Ancient Genomes Reveal a Matrilocal Past

Iron Age Society Centered on Women: Ancient Genomes Reveal a Matrilocal Past

An international team, led by Trinity College Dublin, has unearthed a fascinating glimpse into Britain's Iron Age through ancient DNA. Analysis of over 50 genomes from a Dorset burial site revealed a society structured around female lineage. The study indicates that husbands joined their wives' communities, with land potentially inherited through the maternal line, a system called matrilocality. This pattern wasn't unique to Dorset; similar findings in other Iron Age cemeteries across Britain suggest a widespread phenomenon, challenging traditional views of gender roles and highlighting the significant social and political influence of women in this era. The research published in Nature adds compelling genetic evidence to archaeological observations.

Rethinking SQLite: Surprisingly Powerful at Hyper-Scale

Contrary to popular belief, SQLite isn't just for small applications. This article argues that services like Cloudflare Durable Objects and Turso unlock SQLite's potential at hyper-scale. These platforms assign SQLite databases per entity, replacing the complexities of sharded databases. This approach solves challenges like rigid schemas, difficult schema changes, and complex cross-partition operations. While challenges remain—lack of open-source self-hosting and standardized protocols—SQLite's ACID compliance, efficient I/O, and rich SQL extensions make it a compelling alternative to traditional partitioned databases.

Autumn Billing: Evolving from Publishable Keys to Encrypted Server Actions

A company building a billing system explored various approaches to simplify development, ultimately tackling the challenge of secure frontend payment operations. They initially tried Publishable Keys but encountered limitations in security and functionality. Next, they adopted Next.js Server Actions, but this exposed customer IDs, creating a security vulnerability. Finally, they secured the system by encrypting customer IDs within Server Actions, but this approach depends on Server Actions and lacks framework agnosticism. Future plans involve a more general, framework-agnostic solution that simplifies backend setup.

Why Some UK Gov Services Are Offline at Night: A Legacy Tech Nightmare

This post explores why some DVLA (UK Driver & Vehicle Licensing Agency) digital services are offline overnight. The root cause lies in a complex legacy system, including a 1980s IBM mainframe and a partially completed modernization effort. Facing a choice between years of rebuilding infrastructure or launching a service with nighttime limitations, DVLA chose the latter to deliver value quickly. The article highlights the challenges of digital transformation in large organizations grappling with legacy technology and the difficult decisions involved in balancing speed and long-term stability. The situation underscores how tricky government digitalization can be, even a decade after initial modernization efforts.

The Open Source Maintainer Crisis: Burnout, Pressure, and an Uncertain Future

The Open Source Maintainer Crisis: Burnout, Pressure, and an Uncertain Future

The 2025 State Of Open conference highlighted the plight of open source maintainers: volunteers pour countless hours into projects with little support, leading many to quit or consider quitting. The resignation of Asahi Linux lead Hector Martin due to burnout and demanding users exemplifies this crisis. Maintainers face pressure from users, endless requests, and occasional negativity. Even with minimal corporate sponsorship, the demands far outweigh the support. Surveys reveal many maintainers considering quitting, and many projects may become unmaintained. The problem isn't solely financial; it also requires more contributors to share non-coding tasks like community management and fundraising. But change needs a catalyst—perhaps a major project collapse will finally convince people that paying open source maintainers is crucial.

Generative AI is Eating Away at OSINT Analysts' Critical Thinking

2025-04-03

The increasing reliance on generative AI tools in OSINT (Open Source Intelligence) investigations is leading to a decline in critical thinking among analysts. Studies show that over-reliance on AI reduces critical thinking, making users more susceptible to accepting AI-generated misinformation. Real-world scenarios illustrate the potential dangers of AI in OSINT, highlighting the vital need for manual verification. The article urges OSINT practitioners to prioritize critical thinking, treating AI as a supplementary tool rather than the decision-maker. It advocates for intentionally introducing friction to avoid over-dependence on AI, thus preserving accuracy and integrity in OSINT.

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.

Basel Tax Authority Buys Bahamian Web Address Due to Flyer Error

The Basel-Stadt tax authority had to purchase a web address in the Bahamas due to a mistake on an information flyer for digital tax returns. The flyer, sent to over 100,000 households, omitted the '.ch' from the web address, redirecting users to a '.bs' domain in the Bahamas. While the error has been addressed and the Bahamian address will redirect to the correct Swiss site, the mistake cost the authority CHF 900, significantly cheaper than the estimated CHF 100,000 to reprint the flyers. Taxpayers can still file their returns online, albeit with a brief Caribbean detour.

Typst vs. TeX: A Comparison of Layout Models and a Look Ahead

2025-02-14

This article explores the differences in layout models between the typesetting engines Typst and TeX. TeX, based on boxes and glue, is flexible but lacks awareness of precise positions; Typst uses a region model, allowing elements to react to their position but sacrificing some flexibility. The author analyzes the strengths and weaknesses of both models and points out that Typst, by introducing a re-layout mechanism, is expected to balance flexibility and optimization, addressing current shortcomings in handling complex layouts (such as wrap-around images and pageable tables).

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.
