Four Reasons Why Zoom Meetings Are So Exhausting (and How to Fix It)

2025-01-09

Four Reasons Why Zoom Meetings Are So Exhausting (and How to Fix It)

Stanford researchers have identified four key causes of 'Zoom fatigue': excessive close-up eye contact, constantly seeing yourself on camera, restricted mobility, and increased cognitive load. Excessive eye contact and large face sizes create stress; constantly seeing yourself leads to self-criticism; limited movement and higher cognitive load exacerbate fatigue. Solutions include reducing Zoom window size, hiding self-view, increasing movement, and taking 'audio-only' breaks. A Zoom Exhaustion & Fatigue (ZEF) scale is also being developed to measure the extent of Zoom fatigue.

ICE's Social Media Surveillance Sparks Controversy

U.S. Immigration and Customs Enforcement (ICE) plans to monitor and locate "negative" social media discussions about the agency and its officials, using a new contract. This move has raised concerns about free speech and privacy. While ICE claims it's a response to increased threats against its personnel and facilities, critics argue it could sweep up constitutionally protected speech. The contract may involve digging into users' personal information, including social security numbers and addresses. This follows ICE's previous use of federal contractors for large-scale social media surveillance, fueling concerns about government overreach.

Deconstructing Fenwick Trees with Functional Programming

2025-01-25

This paper delves into the implementation of Fenwick trees (also known as binary indexed trees). Starting with the more readily understandable segment tree, the author uses functional programming and equational reasoning to derive the implementation of Fenwick trees, revealing the logic behind their seemingly mysterious bitwise operations. By cleverly using a Haskell EDSL to operate on infinite two's complement binary numbers, the paper ultimately explains the secret of Fenwick trees' efficient implementation and proves the logarithmic time complexity of its update and range query operations.

Conquering Insomnia: The Healing Power of Creation

The author, a former chronic insomniac, developed a series of quirky rules to combat his sleeplessness, even including avoiding the thought of a particular car air freshener. However, he ultimately discovered that the most effective method was to relinquish control over his sleep, allowing himself to create – writing, drawing, sculpting – whenever inspiration struck in the late hours. This creative process not only dispelled the anxiety of insomnia but also brought unexpected ease and satisfaction. The author encourages readers to try letting go of perfectionism and allow themselves to create, even if they're not good at it, to find healing and release.

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.

LLMs in 2024: A Year of Breakthroughs and Challenges

2024 witnessed a remarkable evolution in Large Language Models (LLMs). Multiple organizations surpassed GPT-4's performance, leading to dramatically increased efficiency—even enabling LLM execution on personal laptops. Multimodal models became commonplace, with voice and video capabilities emerging. Prompt-driven app generation became a commodity, yet universal access to top-tier models lasted only months. While 'agents' remained elusive, the importance of evaluation became paramount. Apple's MLX library excelled, contrasting with its underwhelming 'Apple Intelligence' features. Inference-scaling models rose, lowering costs and improving environmental impact, but also raising concerns about the environmental consequences of new infrastructure. Synthetic training data proved highly effective, but LLM usability remained challenging, knowledge distribution remained uneven, and better critical evaluation is needed.

Poka-Yoke: The Japanese Art of Mistake-Proofing

2025-01-09

Poka-yoke, meaning "mistake-proofing" in Japanese, is a lean manufacturing concept originating from the Toyota Production System. It involves designing mechanisms to prevent, correct, or highlight human errors in a process, thereby eliminating defects. A simple example is a car's clutch pedal—it's a poka-yoke, forcing the driver to depress it before starting the engine. This approach not only improves product quality but also reduces training costs, lessens quality control burdens, and ultimately achieves 100% built-in quality control.
