New research from Texas A&M University reveals that websites are using browser fingerprinting—an obscure method to identify web browsers—to track users across sessions and sites, despite users believing that clearing cookies would maintain their privacy. Dr. Nitesh Saxena, a cybersecurity researcher, emphasized that while fingerprinting has raised concerns, this study provides solid evidence of its use in user tracking. Browsers inadvertently share extensive information like screen resolution and device model, creating a unique fingerprint that is difficult to detect or block.

The content describes a mini-project inspired by a tweet, where the author created a script to analyze download patterns from the Rust package repository, crates.io. The script identifies which crates are downloaded more on weekends (indicating hobby use) versus weekdays (indicating work use). For example, the crate "tokio" was downloaded 2.67 times more on weekdays than weekends. The author shared a bash command to fetch the top 1000 downloaded crates and their usage patterns; they noted that downloading

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 a groundbreaking initiative, the Danish government has enlisted private metal detectorists to explore agricultural fields for historical artifacts. This approach has led to significant discoveries, including a remarkable find by Ole Ginnerup Schytz, who unearthed a cache of gold disks and medallions dating back approximately 1,500 years. These artifacts, which include depictions of Roman emperors and an inscribed bracteate with imagery of Odin, offer profound insights into Denmark's history during a tumultuous

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
