Researchers at The University of Texas at Austin have discovered that the underside of the North American continent is undergoing "cratonic thinning," evidenced by blobs of rock dripping into the Earth's mantle. This phenomenon, detailed in a paper published in Nature Geoscience, represents the first observation of cratonic thinning actively occurring. Lead author Junlin Hua explains that the discovery suggests there is a process below the stable cratons—old rocks that comprise continents—that may lead to their alteration or loss of rock layers

The author is rewriting their software, Bold, and intends to maintain a weekly development log every Saturday to document their progress, ideas, and techniques. They reflect on their initial challenges, noting that while some features like undo/redo and fast rendering were successful, many early code implementations were placeholders as they sought to understand the project's requirements better. A significant oversight was not running the 'find' functionality in the background, leading to performance issues with large files. After five months since the last public beta, they

The content discusses two main topics: a DIY sous vide cooker for perfect steak preparation and an exploration of nitrogen's importance in farming, focusing on Marb, a citizen scientist experimenting with the Birkeland-Eyde process. This outdated method converts atmospheric nitrogen into nitric acid using electrical arcs, but is inefficient for modern farming. Marb has built an experimental reactor to harness this process using an Arduino UNO to manage the electrical arcs, which requires significant power and incorporates systems for air flow and moisture control.

Latency is the time taken for a client request to travel through a network to servers, be processed, and for the response to return. It is a key metric for assessing the responsiveness and efficiency of software systems. Factors influencing latency include: 1. **Physical Distance**: Data travels at finite speeds, so greater distances (e.g., US to European server) increase latency. 2. **Network Congestion**: Overloaded network links cause queuing delays at routers and switches, particularly during peak times

RAF pilots have been advised to keep Tunnock's teacakes in their wrappers until consumed. This follows a historical incident from 1965 when unwrapped teacakes caused a messy explosion in a cockpit after a captain activated an emergency depressurizing switch. After tests in an altitude chamber, the RAF Centre of Aerospace Medicine confirmed that the teacakes do not explode at high altitudes, although the chocolate may crack and the marshmallow filling may puff out. It was noted that frozen te

The author expresses frustration over a growing sense of entitlement among users of open-source software. They emphasize that open-source simply means the source code is available, and does not automatically imply additional support or services, which is at the discretion of the project maintainers. The author criticizes users who demand support without recognizing the efforts of volunteers who create and maintain these projects out of passion. They condemn abusive behavior towards developers and highlight the ridiculous notion that maintainers should be obliged to provide support. Overall, the piece
