Jupyter Notebooks: E2E Testing and Documentation in One

2024-12-18

While developing a quantum computing library, the author leveraged Jupyter Notebooks as both user guides and end-to-end tests. By reading environment variables (like SERVER_URL) within the notebooks, they achieved parameterization, allowing execution by users and automated CI/CD pipelines. Two methods for running notebooks were explored: nbclient for simplicity, and nbconvert/jq for more control but increased complexity. The author opted for nbclient's ease of use, effectively integrating documentation maintenance and code testing, ensuring the integrity of both with every merge request.

Python Meta-Circular Interpreter: Implementing a Python Interpreter in Python

2024-12-18

This article demonstrates how to create a Python meta-circular interpreter (MCI) using Python itself. An MCI is an interpreter written in the language it interprets, allowing implementation of a subset or superset of the host language. The author details the MCI's implementation, covering parsing Python source code, building an Abstract Syntax Tree (AST), traversing the AST and executing statements, and crucial concepts like scoping, symbol tables, and handling control flow statements (e.g., while loops and if statements). This example provides a deep understanding of interpreter mechanics and showcases how to leverage Python's AST module and built-in functions to build more complex interpreters.

Starlink Sells Out in Zimbabwe Amidst High Demand

2024-12-17

Starlink's high-speed satellite internet service quickly sold out in Zimbabwe within weeks of its launch, driven by the country's slow, unreliable, and expensive traditional internet infrastructure. High demand led to sell-outs in major cities like Harare, and even spread to other African countries. Despite higher initial costs, Starlink's unlimited data and superior speeds are proving attractive to many, forcing local providers to lower their prices. While currently facing capacity issues in urban areas, Starlink's potential in rural and underserved regions is significant, boosting related industries such as installation services and accessory sales.

Interpol Drops 'Pig Butchering' Term

2024-12-18

Interpol announced it will no longer use the term "pig butchering" to describe online scams, citing its potential to shame and discourage victims from reporting. The organization believes the term dehumanizes victims and prefers "romance baiting," a term it believes is more sensitive and respectful. This change highlights a shift towards prioritizing victim support and emphasizes the need for more considerate language when discussing sensitive crimes. However, many US law enforcement agencies continue to use the original term.

Frankfurt Silver Amulet Rewrites Early Christian History

2024-12-18

Archaeologists unearthed a groundbreaking artifact in a 3rd-century Roman grave near Frankfurt, Germany: a silver amulet, the "Frankfurt Silver Inscription." Dating back to 230-270 CE, this amulet predates previously known Christian artifacts in the region by almost 50 years. Its inscription, deciphered using advanced technology, contains exclusively Christian content, including invocations to Jesus Christ and biblical quotations. This discovery significantly pushes back the timeline of Christianity's presence north of the Alps, shedding light on its early spread and influence in Roman Germania. The find has major implications for archaeology, theology, and Roman history.

USDA Strengthens Food Safety Measures After Deadly Listeria Outbreaks

2024-12-18

Following two deadly Listeria monocytogenes outbreaks linked to Boar's Head deli meats and Yu Shang ready-to-eat meat and poultry products, resulting in dozens of illnesses and multiple deaths, the USDA's Food Safety and Inspection Service (FSIS) has finally acted. Despite prior knowledge of deficiencies at the Boar's Head facility, FSIS failed to intervene until after the outbreak. The agency announced stronger measures, including expanded testing, improved inspector training, and enhanced facility oversight, to prevent future incidents. This highlights vulnerabilities in food safety regulation and the critical need for prompt and effective intervention.

US Weighs Ban on TP-Link Routers Over Hacking Fears

2024-12-18

The US government is considering a ban on TP-Link routers, a popular Chinese brand, due to national security concerns linked to cyberattacks. Investigations are underway by the Departments of Commerce, Defense, and Justice. TP-Link holds a 65% US market share, largely due to its low prices. A Microsoft report implicated TP-Link routers in ransomware and other cyberattacks launched by Chinese hackers. Investigators allege TP-Link fails to address vulnerabilities, and refuses to cooperate with cybersecurity experts. TP-Link claims its security practices meet industry standards and is committed to addressing US national security concerns. This action reflects broader US concerns about Chinese technology and efforts to restrict imports from China.

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

2024-12-17

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.

Post-WWII Highways: Debunking Myths and Unveiling the Truth

2024-12-17

This article explores key events and misconceptions surrounding the development of highways after World War II. It clarifies that Germany's Autobahn was not initially designed for military purposes, but rather to stimulate the economy and enhance national prestige. While Allied forces utilized the Autobahn in the later stages of WWII, this wasn't its original intent. The article debunks the myth that the US Interstate system was designed with one mile in five being straight and level for emergency bomber landings, explaining its true purpose was civilian benefit and economic development, although it also served military needs, such as troop movement and industrial production. Finally, the article reviews post-WWII attempts and exercises by various militaries to utilize highways as emergency runways for aircraft, highlighting their limitations and ultimate replacement by dedicated airfields.

Whittaker's Keynote at NDSS 2024: AI, Encryption, and a New Era of Threats

2024-12-18

At the 2024 NDSS Symposium, Meredith Whittaker, president of the Signal Foundation, delivered a keynote address reflecting on the 'Crypto Wars' of the 90s. She highlighted how political, technical, and commercial pressures have shaped today's encryption landscape. Whittaker warned against viewing the current situation as simply 'Crypto Wars 2.0,' arguing that an economic engine driven by personal data, surveillance technology, and AI/ML poses a fundamentally different threat than the government-dominated encryption landscape of the 90s. She stressed the need for a new approach, with NDSS research at the forefront of this response.

RTO Mandates Lead to Tech Talent Exodus, Study Finds

2024-12-17

A study tracking over 3 million employees at 54 S&P 500 high-tech and financial firms reveals that return-to-office (RTO) mandates are causing companies to lose top talent and struggle to find replacements. The research found a 14 percent average increase in employee turnover after RTO policies were implemented, with senior and skilled employees more likely to leave. Women experienced nearly three times the attrition rate of men. Furthermore, RTO mandates prolonged hiring times and increased costs. Companies' attempts to enforce RTO policies through surveillance tactics, such as VPN tracking and badge swipe monitoring, fueled employee resentment and furthered the exodus. The study suggests that RTO mandates reflect a culture of distrust and ineffective management, leading to decreased employee engagement.
