К каким социальным проблемам приводит неправильная последовательность глав в учебнике по программированию

Сегодня видел план вводного курса, написанный начинающей американской преподавательницей. План иллюстрирует распостраненную ошибку - неправильный порядок подачи материала:

Zephyr RTOS 〜 debug with VSCode 〜 - Qiita

1. はじめにこれまで Zephyr を紹介する際、何度か下記リポジトリをベースに解説してきました。このリポジトリは、実運用を想定した環境構築手順とデバッグ環境を提供しており、本記事では、これを使った VSCode と連携したデバッグや書き込みなどの使い方につ...

Those who learned #computing in the 1970s and 1980s—from the signal-level up, on trainers like KIM-1 or Heathkit ET-3400—often get the urge to stroll down Memory Lane, the full 256-byte length of it. They need not spend thousands of dollars on eBay to purchase a beaten, broken, fifty-year-old trainer; they could just grab the wonderful Black Pill #STM32 F411 Cortex board on #AliExpress for $0.99.

Or, try the fabulous #ESP32 C3 RISV-V board, with an OLED display, WiFi, and BLE for the same amount of money.

These thumb-sized #MCU boards are more capable than the 1980s room-sized super-minicomputers. The F411, for example, has a 32-bit 100 MHz Cortex-M4F with FPU, 256 KB SRAM, and 512 KB Flash.

These boards can be programmed in assembly or the usual assortment of open-source, higher-level #programming languages, like Forth, C, C++, Go, Rust, Zig, Ada, etc., and even Processing, Python, and JavaScript.

A good selection of open-source #RTOS are available, too: FreeRTOS, Zephyr, ChibiOS, and the like.

Go ahead; by a bucket load of MCU boards from AliExpress, relive those happier simpler times, and simultaneously buck the stupid #tariffs.

Now, with textures on a regular Pi #Pico (non-W), running on top of Apache #NuttX #RTOS

You could say now that Apache NuttX kinda, sorta, almost, but-not-really supports #OpenGL ES 1.0 CL (albeit in a very incomplete form).

There are some bugs with the colour and lighting interpolation, so while it's computed, the contribution towards the final fragment were discarded.

Also, the display is a different one, ST7735S-based, since it play nicer with NuttX.

Zepyhr RTOS (MCU OS) has support for WireGuard VPN now 🔒

„The networking stack also gains support for WireGuard VPN, enabling secure, low-overhead tunneling directly on your Zephyr devices. WireGuard is known for its simplicity, speed, and strong cryptography, making it an ideal fit for resource-constrained embedded devices that need secure remote management or encrypted data transport.“
