Grammarly Extension Breaks Website Layout with CSS Conflict

A website builder discovered that the Grammarly browser extension was breaking their website's layout. Grammarly injects a stylesheet that overrides the website's own styles, particularly by using the same custom property `--rem`, causing the website's fluid typography system to malfunction. The author fixed the issue using a mutation observer and the custom property `--🤡`, and called on Grammarly to improve its extension's design to avoid conflicts with other websites' styles.

Chimpanzees Exhibit Engineering Skills in Tool Making

A new study reveals that chimpanzees in Tanzania's Gombe Stream National Park exhibit engineering skills when crafting termite-fishing tools. Researchers found that chimpanzees selectively choose plants, favoring more flexible materials over stiffer alternatives. The preferred plants were 175% more flexible than those not used. This suggests chimpanzees possess a form of 'folk physics,' understanding material properties to optimize tool effectiveness. The findings offer crucial insights into the evolution of human tool use and provide a novel perspective on early human technology.

Tracking Code Changes with Git Hooks: A Data-Driven Approach to Development

2025-03-29

This article presents a method for tracking code modification time using Git hooks to provide a more objective measure of development efficiency. By recording the time from branch creation to merge, excluding thinking time, it offers a clearer reflection of actual coding time. This approach helps teams identify and address inefficiencies in code maintenance, such as excessively long maintenance times for certain components, or efficiency gains from AI tools. The ultimate goal is to optimize the development process, reduce entropy, and boost team productivity through data-driven insights rather than subjective estimations.

NASA Adds SpaceX's Starship to Launch Services Contract Despite Setbacks

Despite recent major setbacks in Starship's past two flights, NASA has added SpaceX's still-experimental rocket to its launch services contract. This opens the door for Starship to potentially carry future NASA science missions, pending a successful orbital flight. The contract, which already includes Falcon 9 and Falcon Heavy, features an on-ramp provision for new providers. While Starship's reliability remains a concern, this decision offers NASA a potential crewed lunar lander for Artemis III in 2024 and an option for its planned 2026 uncrewed Mars mission.

US Crackdown on Dissent Silences Foreign Scientists

The US government's increasing crackdown on dissent is creating a climate of fear for foreign scientists, who risk visa cancellation, detention, and deportation for expressing critical views. The article details numerous cases of foreign students and scholars detained or deported for criticizing government policies. Universities are complying with the administration's demands for greater control over protests and faculty, in exchange for federal funding, even canceling DEI programs. Furthermore, the government is canceling research grants on topics like LGBT+ health, poverty's impact, and climate change. This chilling effect is silencing many foreign scientists and severely hindering scientific progress.

Beyond OOP: The Evolution of Subtyping in Programming Languages

2025-03-29

This article explores the crucial role of subtyping in programming language design. The author, drawing on their experience developing several programming languages, explains that subtyping is not limited to class inheritance in object-oriented programming but is a more fundamental concept: type X is a subtype of type Y if a value of type X can be used wherever a value of type Y is expected. The article clearly explains why subtyping is crucial even in performance-oriented low-level languages, enabling the compiler to statically check for null values, aliasing, and other issues, thereby improving code reliability and ultimately driving the evolution of programming languages.

Elixir's BEAM VM: Busy Waiting – Optimization or Resource Hog?

2025-03-29

Benchmarking Go, Elixir, and Node.js revealed Elixir (on the BEAM VM) exhibited high CPU usage despite excellent responsiveness. The culprit? Busy waiting, a BEAM optimization maximizing responsiveness. While misleading OS-reported CPU usage, enabling busy waiting is beneficial for HTTP workloads on dedicated hardware. However, disabling it is recommended on systems sharing kernels with other software or cloud burstable instances to prevent impacting other processes. Tests showed no performance difference with busy waiting disabled for HTTP requests.

Pentagon Purges DEI Content: Historical Photos Among Thousands Flagged for Removal

The Department of Defense is undertaking a massive purge of diversity, equity, and inclusion (DEI) content from its websites and social media, targeting over 26,000 images. This includes photos of a World War II Medal of Honor recipient, the Enola Gay, and the first women to graduate from Marine infantry training. The action stems from President Trump's executive order ending DEI programs across the federal government. The purge has led to confusion, with images containing the word "gay" mistakenly flagged for removal, impacting both individuals with that surname and the aircraft itself. Historically significant photos, such as those of the Tuskegee Airmen, may be spared. The Pentagon claims it's working to comply rapidly, but the process is proving time-consuming and complex.

Banned from MSG for a T-Shirt He Designed Years Ago?

Frank Miller, a graphic designer, was banned for life from Madison Square Garden (MSG) and its properties, including Radio City Music Hall, for an incident he claims he wasn't even involved in. The ban stems from a "Ban Dolan" T-shirt he designed in 2017, referencing a conflict between Knicks owner James Dolan and Charles Oakley. Although Miller wasn't wearing the shirt and hadn't attended an MSG event in almost two decades, he was identified, likely via facial recognition technology, and denied entry to a concert on his parents' anniversary. MSG claims his actions violated their code of conduct, but Miller argues this highlights the potential misuse of facial recognition and corporate power, raising concerns about privacy and surveillance.

Testing Without Mocks: A Novel Approach to Unit Testing

2025-03-29

This article presents a novel approach to unit testing that eliminates the need for mocks and spies, resulting in fast, reliable, and maintainable tests. The core idea involves combining state-based testing with a new infrastructure technique called "Nullables." Nullables aren't test doubles; they're production code with an "off" switch, allowing tests to run without relying on external systems or state. While requiring modifications to production code, this approach avoids many drawbacks of traditional methods, such as flaky tests and difficult refactoring, and offers significant performance gains. The article thoroughly explains the patterns and techniques involved, including Narrow Tests, State-Based Tests, and Overlapping Sociable Tests, providing ample code examples and diverse use cases, making it ideal for developers to learn and implement.
