Photos can leak home GPS coordinates via hidden metadata, JavaScript fix exists

·2 views

Smartphones embed hidden EXIF metadata in photos, including precise GPS coordinates, device details, and timestamps. This data can reveal exact home addresses and daily routines when original photos are shared online. The article explains the technical structure of JPEG files where this metadata is stored. It proposes a client-side JavaScript solution using HTML5 Canvas to strip EXIF data without uploading images to external servers. This approach preserves privacy by removing location and device information before sharing.

Common belief that C# structs live on the stack is inaccurate

A widespread misconception among developers holds that C# structs are always allocated on the stack while classes use the heap. In reality, structs can reside on either the stack or heap depending on their declaring container. Value types are stored directly within their container's memory, not at a fixed location. This misunderstanding can lead to unexpected garbage collection behavior and performance issues.
