Episode notes
Bill C-22 Enables Mass Metadata Collection
- Canada's Bill C-22 enables warrantless collection and analysis of large-scale telecom metadata by law enforcement.
- The system forces providers to retain and grant access to call logs, text metadata, and online activity, raising privacy and breach risks.
Chrome DevTools Moves To Real Time MVC
- Chrome DevTools MCP 2025 proposes a model view controller to enable real-time, bi-directional state manipulation between browser and devtools.
- It uses web sockets for persistent connections to lower latency for live debugging and performance tuning.
How A 49MB Webpage Still Feels Fast
- A 49MB webpage can remain performant by combining advanced compression, modular chunking, lazy loading, and progressive enhancement.
- Breaking assets into demand-loaded pieces reduces initial load while preserving rich media for interactive sites.
