Modernize your .NET apps for Windows Arm64 with GitHub Copilot

The GitHub Copilot upgrade agent now supports migrating .NET applications from Windows x64 or x86 to Windows Arm64. It assesses your projects, flags blockers like architecture-tied build settings and native dependencies without Arm64 binaries, then builds a migration plan. The agent updates code, dependencies, and project configuration, and builds the migrated app for Arm64, running tests when matching hardware or CI runners are available. It focuses on portability and correctness, not Arm64 performance tuning. To start, install GitHub Copilot upgrade, pick the .NET Arm64 migration scenario, and review its plan before letting it make changes.

Toddler Phone Calls Family And No One Else

A hobbyist built a toddler-safe telephone that can only call pre-set family contacts. An ESP32-S3 acts as a USB host for a commercial retro-style handset and runs a minimal SIP client connecting over WiFi to a VoIP account, in this case Twilio. There are no inbound calls, so there's no risk of scam calls. Each contact gets an arcade button that lights up based on that contact's time zone, and a text-to-speech voice announces network errors or when it isn't call time.

I stopped buying dedicated dash cams after realizing my old phone does it better

Thay vì mua thiết bị dash cam chuyên dụng, tác giả nhận ra chiếc điện thoại cũ hoàn toàn có thể thay thế với chi phí bằng không. Nguyên nhân kỹ thuật là nhờ vào các tính năng như Continuous Video Recording (CVR) và ứng dụng như DailyRoads Voyager, điện thoại cũ có thể ghi hình liên tục mà không cần thiết bị bổ sung. Hệ quả là tiết kiệm đáng kể chi phí (thường từ 50 đến 200 USD cho thiết bị chuyên dụng) và vẫn đảm bảo ghi lại video chất lượng tốt trong điều kiện lái xe. Điều đáng học hỏi là việc tái sử dụng thiết bị điện tử hiện có vừa kinh tế vừa thân thiện với môi trường, tránh lãng phí tài nguyên.

Điện thoại cũ của bạn có thể thay thế camera hành trình một cách hiệu quả và tiết kiệm chi phí.
