The Curious Case of Consumer Routers and Weak Power Supplies

A senior computer scientist recounts two incidents highlighting performance issues with consumer-grade routers stemming from inadequate power supplies. The first involved the author's home router, exhibiting slowness when powered by a solar inverter. The second occurred in Kiribati during an ISIF Asia-funded project. Using an oscilloscope, the author observed the router drawing excessive current during voltage dips, leading to instability. Adding capacitors to stabilize the power supply resolved the issues, underscoring how seemingly minor power problems can cause significant network failures.

Web Server Listen Overflows Traced to a Linux Kernel Performance Issue

2025-02-14

Upgrading web servers from CentOS to Ubuntu led to listen overflow errors. Investigation revealed a system CPU spike on newly booted Ubuntu hosts within minutes of startup, causing slow web request processing and subsequent listen overflows. The culprit was inode cgroup switching in the Linux kernel; after writing many files, the kernel spent significant time moving inodes between cgroups. Disabling the io or memory controllers in systemd resolved the issue. CentOS was unaffected as it uses cgroups v1, unlike Ubuntu's cgroups v2. A minimal reproduction script was created to demonstrate the issue.

The Subtle Art of the En Dash and Em Dash

This article clearly explains the difference in usage between en dashes and em dashes, and how to efficiently insert them in Word and Google Docs. The author uses vivid examples to illustrate that en dashes are used for ranges (e.g., time range 7–10pm), while em dashes are used for emphasis, parenthetical asides, or abrupt breaks in speech. The article also compares these two symbols with hyphens and provides several shortcut keys and manual insertion methods to help readers avoid ambiguity caused by improper punctuation.

Reverse Engineering Stunts: SuperSight Mod Development Log (Part I)

2025-08-17

Alberto Marnetto details his journey creating SuperSight, a graphical enhancement mod for the classic racing game Stunts. The article chronicles his reverse engineering process, leveraging the community-driven Restunts project (containing partially disassembled code and C-language ports) to understand the game's rendering engine. Initial attempts to modify graphics settings via the in-game menu proved difficult due to the game's lack of option saving. By analyzing Restunts' code, he pinpointed the variable controlling graphical detail. He then implemented simple enhancements like altering the field of view, encountering and documenting minor glitches. This successful proof of concept paves the way for further improvements detailed in future parts.

Supersonic Passenger Travel: A Risky Bet with Huge Potential?

The dream of supersonic passenger travel is back, but unlike Concorde, today's startups and giants aim to overcome the challenges that led to Concorde's failure—high operating costs and poor fuel efficiency—through new materials, advanced propulsion, and sustainable fuels. However, supersonic and hypersonic flight inherently require more fuel and have greater environmental impact. The initial market will focus on high-value business and luxury travelers, offering massive potential, but commercialization is at least a decade away, and investment risks remain high.

The Secret Weapon for Diffusing Toxic Meetings: Naming What's Happening

The Secret Weapon for Diffusing Toxic Meetings: Naming What's Happening

This article reveals a powerful technique for resolving conflict in meetings: simply stating what's happening in the room. The author argues that many meetings devolve into unproductive arguments due to clashing priorities, emotions, and unspoken tensions. Instead of engaging in the conflict, the solution is to directly name the collective experience, e.g., "I'm sensing a lot of frustration in the room." This disrupts negative patterns, creates shared awareness, and paves the way for more productive communication and problem-solving. The article provides tactical tips, including using "I" statements, avoiding singling out individuals, and knowing when to escalate.

LLM Identity Confusion: A Crisis of Trust Emerges

LLM Identity Confusion: A Crisis of Trust Emerges

A recent study reveals widespread "identity confusion" in Large Language Models (LLMs). Researchers found that over 25% of LLMs exhibit misrepresentation of their origins or identities, primarily stemming from model hallucinations rather than replication or reuse. This identity confusion significantly erodes user trust, especially in critical tasks like education and professional use, surpassing the negative impact of logical errors. The findings highlight the systemic risks posed by LLM identity confusion and call for greater attention to model reliability and trustworthiness.

Google Search's AI Revolution: AI Mode Arrives

Google is accelerating the AI-ification of its search engine. Their latest offering, "AI Mode," a search-centric chatbot, is poised to transform how users interact with search. This mode uses Google's search index to generate answers, interspersed with a few supporting links, similar to Gemini or other chatbots, but better at leveraging real-time data and interacting directly with the web. This move signals the growing importance of AI-generated content to Google Search, despite ongoing issues with its models. Google is also expanding AI Overviews to handle more complex queries, such as math and coding. While concerns exist about reduced reliance on website links, Google states AI Mode and AI Overviews are designed to supplement, not replace, traditional search results, attracting new users and increasing engagement.

The Harvard Blood Factory: How a Pure Scientist Won WWII

Edwin Cohn, a temperamental Harvard protein chemist, unexpectedly transformed his lab into a highly effective applied R&D powerhouse during WWII. Initially focused on theoretical research, the war spurred him to lead his team in inventing methods to produce life-saving albumin from blood. Cohn's team not only created albumin more stable than plasma but also developed other blood products for treating battlefield injuries. While his methods are outdated, his ability to translate lab discoveries into commercial-scale products remains a valuable lesson. Cohn's story offers a compelling case study for science organizations and funders: combining a pilot plant, funding, and vision to tackle significant problems can yield extraordinary results in translating research into real-world impact.

Legacy Code Adventures: A COBOL Odyssey

2025-05-22

Maintaining 200k lines of COBOL code unearthed a treasure trove of ingenious hacks and historical quirks. The author discovered base-10 numerics, clever string parsing using data definitions, and a 'REDEFINES' statement used for internationalization (even with Spanish redefinitions!). Early exits were implemented for abrupt job termination, and a file mysteriously contained the first 800 natural numbers as string constants. The story concludes with the revelation that the UNIX 'dd' command originates from COBOL's 'DD' statement for data definition, showcasing the unexpected legacy of mainframe programming.

Trump's Tariff War: Canada and Mexico's Oil Industry Takes a Hit

The Trump administration's imposition of hefty tariffs on Canadian and Mexican oil products has sparked widespread concern. This move could lead to a 10% increase in gasoline prices in the U.S. Midwest and severely impact Canadian and Mexican oil exports. Experts point out the high dependence of the U.S. on Canadian heavy crude oil, with limited substitutes, meaning tariffs will directly translate to higher consumer prices. Mexico may redirect its oil exports to Asian and European markets. This event highlights the tense relationship between the U.S. and its major trading partners, and the impact of tariff policies on the global energy market.
