**I built an app to stop me doomscrolling by touching grass**
A person developed a mobile application to curb their excessive phone use, specifically the habit of "doomscrolling." The app's core functionality encourages users to engage in outdoor activities as a means of distraction and digital detox. The app likely leverages location services or other tracking methods to monitor time spent outdoors.
The motivation behind creating the app stemmed from a personal struggle with excessive phone usage and its negative impacts. The app's design aims to replace unproductive screen time with beneficial real-world engagement. By prompting outdoor activities, the app aims to improve mental well-being and reduce feelings of anxiety or frustration associated with endless scrolling. The success hinges on the user's active participation and commitment to using the app as intended.

**Making any integer with four 2s**
The puzzle involves creating any integer using only four instances of the number 2. Elementary school children can solve this for smaller integers using basic arithmetic. Middle schoolers, with knowledge of exponents and factorials, can significantly expand the range of solvable integers. More advanced techniques, such as the Gamma function, complex numbers, integrals, repeating fractions, and combinatorial operators, allow for even greater flexibility, making even notoriously difficult numbers like 7 attainable. The puzzle's appeal spans various mathematical skill levels, providing a challenge for people of all ages and mathematical backgrounds.
The puzzle's history shows it was a popular pastime among mathematicians in the 1920s. A general solution, utilizing nested square roots, was eventually discovered by Paul Dirac, effectively solving the puzzle completely. The puzzle demonstrates how different mathematical tools and concepts can be creatively applied to achieve a seemingly simple goal, showcasing the elegance and versatility of mathematics.

**WhiteSur: macOS-like theme for GTK desktops**
WhiteSur is a macOS-like theme for GTK-based Linux desktops. It aims to provide a familiar macOS aesthetic to users of Linux distributions. The project is available on GitHub and can be installed using a provided shell script. The installation script handles necessary dependencies.
The theme's compatibility is affected by the increasing use of libadwaita in newer GNOME versions (43.0 and later). Libadwaita's lack of custom theme support limits WhiteSur's effectiveness on applications utilizing it; users wishing to apply the theme to these apps must resort to overwriting specific configuration files. The project developer encourages donations and actively incorporates user feedback.

**Thailand to Cut Power to Myanmar Scam Hubs**
Thailand's government, led by Deputy Prime Minister Phumtham Wechayachai, will sever electricity, oil, and internet access to five Myanmar locations—in Payathonzu, Tachileik, and Myawaddy townships—starting at 9 a.m. on Wednesday. This drastic action targets suspected Chinese-run call centers engaged in widespread scams that have cost Thailand an estimated 80 million baht daily, totaling 86 billion baht in losses. The decision prioritizes national security over economic considerations, reflecting the severity of the fraudulent activities impacting Thailand, China, and other countries.
The government's strategy involves a coordinated shutdown of essential services to disrupt the operation of these scam hubs. The involved officials included key figures from the Interior Ministry, National Security Council, and the Provincial Electricity Authority. The crackdown aims to curb the significant financial damage and the broader security risks posed by these transnational criminal operations.

**Vietnamese Graphic Design**
Vietnamese graphic design is the subject. The provided information only lists "Filters, Medium, Year" as content, suggesting a framework for analyzing or categorizing examples of Vietnamese graphic design rather than a description of the design itself. This implies that a study or collection of Vietnamese graphic design works could be organized according to filters (e.g., style, purpose, designer), medium (e.g., print, digital, film), and year of creation. The "when" is therefore unspecified, and the "where" is Vietnam. The "why" is also implicit; the categorization suggests an intent to analyze trends, stylistic changes, or the historical evolution of the field over time. The "how" is via the application of filtering, medium identification, and chronological ordering. The main takeaway is that a structured approach to the study of Vietnamese graphic design is being proposed, which could reveal insights into its development and characteristics.

**Half-Life**
Valve's *Half-Life*, released around 1998, aimed to elevate the first-person shooter genre beyond simple entertainment. The development team prioritized integrating narrative and gameplay seamlessly, rejecting the use of cinematic cutscenes to maintain a cohesive experience. This decision, though challenging, reflected their ambition to create a game that was more than just a "throwaway toy," a goal that contrasted with the prevailing trend in the FPS market at the time.
The FPS genre in 1998 was saturated with games, most of which focused on technological advancements rather than innovative game design. *Half-Life* stood out by prioritizing a strong narrative and integrated gameplay, pushing the boundaries of the medium despite its imperfections. The game's lasting impact is demonstrated by its eventual inclusion in the Smithsonian, a testament to its significance within video game history. The team's dedication to creating a unified narrative experience and its impact on the FPS genre are key elements that defined the game's legacy.
