    Making Visual Studio a bit more visual

    Developers frequently work with various image references in their code, but the string values don't show the actual images. A new feature in Visual Studio introduces an editor tooltip that previews images when hovered over, showing the original size capped at 500 pixels, along with the image's dimensions and file size. This feature currently supports common file types like PNG, JPG, and WebP, among others. Experiment feedback has led to the ability to click for a full view in an external viewer, while features like zoom are considered for future updates. Available in Visual Studio 2022 v17.10 or newer.

    The Decline Of Mobile Development

    Mobile development for Android and iOS has become increasingly frustrating due to frequent OS updates requiring new compliance measures that complicate codebases. Developers face restrictive actions if their apps aren't updated in time, taking away from feature development and inflating costs. Many developers find the constant hoop-jumping and convoluted design patterns discouraging, leading them to switch to web development where they can build faster with fewer constraints. Google and Apple's control over app ecosystems and mandatory in-app purchases further dissuade developers. As a result, many are leaving mobile development in favor of the web.

    Progressive Web Apps vs. Native Apps: Which Works Best for Your Business?

    Progressive Web Apps (PWAs) and Native Apps offer distinct advantages and limitations for businesses developing mobile applications.

    Samsung’s new image-generating AI tool is a little too good

    Samsung's new 'sketch to image' AI tool on the Fold 6 phone generates impressive and sometimes eerily realistic images from basic sketches. While the feature is entertaining, its accuracy raises concerns about distinguishing real from fake images. The tool's ability to seamlessly integrate AI-generated elements into photos could complicate our understanding of authenticity in imagery, especially with how instinctive it is to use.

    How did Facebook intercept their competitor's encrypted mobile app traffic?

    Facebook is facing a class action lawsuit over claims that it intercepted encrypted traffic from the Onavo Protect app to gain competitive insights. Using techniques akin to a MITM attack, Facebook allegedly decrypted specific domains' traffic by prompting users to install a CA certificate. However, improved security measures in newer Android versions prevented this from being feasible. The core controversy lies in whether the data interception was legal or ethical. The continued analysis of archived app versions and court documents sheds light on Facebook's methods and the technical challenges involved.
