Смысл: The main idea is to introduce the Data Matrix 2D barcode technology to tech enthusiasts and demonstrate how it can be used creatively to store and transmit information via mobile devices.
A guide for geeks on how to generate and use Data Matrix 2D barcodes for creative purposes like anti-spam contact sharing and digital business cards.
Смысл: The main idea is to demonstrate how animated, high-density visual codes like TXQR and Cimbar can enable the wireless transfer of relatively large files between devices using only a screen and a camera, bypassing traditional network protocols.
The text explains how animated visual codes, specifically TXQR and Cimbar, enable air-gapped file transfers via smartphone cameras at speeds up to 800 KB/s.
Смысл: The text demonstrates the technical feasibility of using animated QR codes for one-way data transfer in network-restricted environments and showcases the versatility of the Go language for cross-platform development (Mobile, Web, and Backend).
The author built a cross-platform system using Go, Gomobile, and GopherJS to transfer files via animated QR codes, achieving speeds up to 9KB/s.
