The content discusses a new feature for importing JSON files in JavaScript modules, which simplifies the process by allowing direct imports without the need for additional parsing methods like JSON.parse() or using fetch(). This is made possible by JSON module scripts and the use of an import attribute specifying `type: "json"`. The browser automatically recognizes that the imported file is JSON, making it ready to use immediately. For successful imports, the HTTP response must have a JSON MIME type, such as `Content-Type: text

The author shares their experience of using a solar-powered setup to process OCR requests with an old iPhone 8, instead of using a Mac, over the course of a year. Their project has handled 83,418 OCR requests and processed 48GB of images using Apple's Vision framework. The author repurposed an idle EcoFlow River 2 Pro for renewable energy, finding modest financial savings in energy costs (around $8 monthly). Although the practicality of this setup is debatable, the author

Graph search algorithms, like A*, are used to find the shortest path on maps represented as graphs. These algorithms process a graph, which consists of nodes (locations) and edges (connections) between them, to yield results such as shortest paths, distance maps, and more. A* operates solely on the graph data, not considering external factors like the physical environment or dimensions. It outputs a path made up of graph nodes and edges, leaving interpretation of movement (e.g., through a doorway or across

In the article "When agile experimentation at startups becomes a p-hacking trap," Thaís Steinmuller discusses how the urgency to deliver results in startups can lead to p-hacking, where teams prematurely report positive findings. The author illustrates this through a scenario where a product manager tests four layout designs for a website dashboard, aiming to enhance user signups. The team plans to adopt the design with a p-value below 0.05 to indicate a statistically significant improvement. However, testing multiple designs increases

Software plays a crucial role in our daily lives, as we constantly use computers and apps, which are often mass-produced or customized for large enterprises. However, there is a lack of "home-made software" — personalized apps created by individuals for specific needs of friends and family. John and Pontus have explored this concept and developed a research prototype called Scrappy, aimed at facilitating the creation of simple, personal applications ("Scrapps"). Scrappy serves as a tool to envision home-made software as creative and
