WordPress Battles Private Equity: A Fight for the Future of Open Source

2024-12-12

WordPress, the world's leading content management system, is locked in a battle with private equity firm Silver Lake and its investment, WP Engine. After receiving massive investment, WP Engine, a for-profit company built on WordPress, has aggressively exploited the WordPress trademark while contributing minimally back to the open-source community. After repeated attempts at communication failed, Automattic CEO and WordPress co-founder Matt Mullenweg took action, restricting WP Engine's access to WordPress.org resources to defend the open-source community and the future of WordPress. This conflict highlights the fundamental conflict between open-source communities and profit-maximizing private equity firms, serving as a cautionary tale about the long-term health of open-source projects.

Demonic Possession Predicted the Fall of the Carolingian Empire

2024-12-13

In the early 9th century, a Frankish courtier recorded a tale of demonic possession. The demon, Wiggo, confessed to destroying crops, livestock, and spreading plagues, blaming the Franks' sins and their rulers' many crimes. Wiggo described rampant greed, mutual suspicion among rulers, and lack of piety. This story mirrored the crisis of the Carolingian Empire: internal strife, economic instability, and famine. The courtier, Einhard, used this tale to subtly criticize the rulers' corruption and foreshadow the empire's decline.

Revolutionary Idea: Applying Magit Principles to the jj Version Control System

2024-12-13

The author proposes a novel approach: applying the Magit version control interface from Emacs (which uses text files as its UI) to the nascent jj version control ecosystem. The article points out that Magit's text-based UI offers efficiency and portability. By leveraging the LSP protocol, a Magit-like experience can be implemented in various editors, avoiding redundant development. The author envisions generating specific text files (such as .jj/status.jj) and utilizing LSP features like semantic tokens, folding ranges, and goto definition to achieve Magit-like version control operations. The ultimate goal is to create a cross-platform, efficient user interface for jj version control.

NASA Solves Ingenuity Mars Helicopter Crash Mystery

2024-12-13

After nearly a year of investigation, NASA has finally solved the mystery behind the crash of Ingenuity, the Mars helicopter carried by the Perseverance rover. The helicopter's navigation system, unable to discern sufficient features on the relatively smooth Martian surface, resulted in a horizontal velocity upon landing. This caused Ingenuity to tumble, breaking its blades. Despite lacking a black box, investigators pieced together the cause from limited data and imagery. Remarkably, Ingenuity still communicates intermittently with Perseverance. The incident has prompted NASA to begin planning for follow-on missions, including a larger Mars helicopter capable of carrying scientific instruments.

Mirror Bacteria Research Raises Significant Risks, Scientists Warn

2024-12-13

Synthetic biologists have achieved remarkable breakthroughs, such as creating bacteria with chemically synthesized genomes. However, two synthetic biologists recently joined other scientists in calling for a halt to research that could lead to the creation of "mirror bacteria." These bacteria are composed of the same components as natural cells but with opposite stereochemistry in all biopolymers. Because mirror bacteria might lack natural predators and evade immune systems, they pose a catastrophic risk. The article emphasizes that while scientific research should be open, certain research, like mirror bacteria research, is too risky given the potential for devastating consequences. Therefore, it should be stopped.

CCxTrust: A Confidential Computing Platform Leveraging Collaborative Trust from TEE and TPM

2024-12-12

CCxTrust is a novel confidential computing platform that cleverly combines the strengths of Trusted Execution Environments (TEEs) and Trusted Platform Modules (TPMs) to establish a collaborative trust framework. By leveraging the black-box Root of Trust (RoT) embedded in CPU-TEEs and the flexible white-box RoT of TPMs, CCxTrust achieves end-to-end protection of sensitive data and models, overcoming the limitations of relying on a single hardware RoT. The platform implements independent Roots of Trust for Measurement (RTM) and a collaborative Root of Trust for Report (RTR), further enhanced by a composite attestation protocol for improved security and efficiency. Experimental results demonstrate significant performance advantages.

The World of Tomorrow: Why Did Progress Lose Its Glamour?

2024-12-12

This article explores the allure and subsequent fading of the 'World of Tomorrow' vision prevalent in the mid-20th century. It traces the evolution of societal yearnings for a better future, from the pursuit of efficiency, order, and speed to desires for exploration, adventure, and achievement, and finally, the longing for security, comfort, and ease. However, as technological advancements became reality, their flaws emerged, such as the blandness of industrialized food and the destructive nature of urban renewal projects. The author argues that disillusionment with progress stems from a misunderstanding of progress itself – the pursuit of 'one best way' rather than acknowledging diversity and individual preferences. To regain progress's charm, understanding contemporary aspirations and providing possibilities for various lifestyles, rather than a single future blueprint, is crucial.

Pink Floyd's 'The Wall': A Descent into Isolation and the Search for Meaning

2024-12-12

Pink Floyd's 'The Wall' is a groundbreaking concept album chronicling the fictional Pink's journey from childhood trauma to self-imposed isolation. Haunted by the loss of his father in World War II, a domineering mother, and the crushing weight of fame, Pink constructs a metaphorical wall to shield himself from emotional pain. This wall, built brick by brick through life's hardships, leads him to the brink of insanity. Yet, the narrative explores themes of freedom and responsibility, culminating in a theatrical mental trial that leaves the listener questioning the nature of life, loss, and redemption. Inspired by Roger Waters' personal experiences and disillusionment with stardom, 'The Wall' remains a powerful and enduring piece of musical art.

The AI chatbot ChatGPT has sparked controversy due to its built-in name filters. These filters prevent users from mentioning certain names, such as Brian Hood, Jonathan Turley, and Jonathan Zittrain, causing chat interruptions. The reason for filtering these names stems from previous instances where ChatGPT incorrectly generated information about these individuals, leading to legal disputes. While OpenAI claims the filtering of "David Mayer" was a glitch, the incident highlights the challenges LLMs face in handling sensitive information and the potential problems hard-coded filters can create.

The Git project is embroiled in a heated debate over the integration of the Rust programming language. Proponents argue that Rust's memory safety and ease of refactoring would enhance Git's security and developer experience. However, opponents express concerns that Rust integration could compromise support for niche platforms like NonStop, potentially hindering Git's long-term viability. NonStop's prevalence in the financial sector, its reliance on Git, and the lack of a Rust compiler for the platform complicate the issue. The discussion ultimately reached no resolution, leaving the Git project grappling with a critical decision between maintaining broad platform support and improving security and developer experience.

New Study Pinpoints Neanderthal Interbreeding with Modern Humans

2024-12-13

A new analysis of ancient DNA from modern humans in Europe and Asia has precisely determined the timeframe of Neanderthal interbreeding with Homo sapiens. The interbreeding began approximately 50,500 years ago and lasted for about 7,000 years, until Neanderthals began to disappear. This research, using 58 ancient genomes and present-day human genomes, revealed an average interbreeding date of around 47,000 years ago, consistent with archeological evidence. The study also found that East Asians possess about 20% more Neanderthal genes than Europeans and West Asians, potentially due to the presence of mixed genes when modern humans migrated eastward around 47,000 years ago. The findings offer a more complete picture of past human migrations and gene flow, and shed light on the impact of Neanderthal genes on modern human health.
