New Embedded Programming Language by Apple

The last week at WWDC 2024, Apple showed its new programming language for resource-constrained systems. Embedded Swift is a specialized version of Apple's 🖥 Swift programming language designed for microcontrollers like the 🇨🇳 ESP32, 🍓 Raspberry Pi RP2040, 🦋 STM32. It enables the development of IoT and low-power devices with Swift's familiar syntax and features.

Features of the language:
➡️Supports value and reference types, closures, optionals, and error handling
➡️Designed for the constrained environments of microcontrollers
➡️Seamlessly integrates with existing C and C++ SDKs
➡️Wide range of supported microcontrollers and plenty of code examples

Embedded Swift brings the benefits of Swift's ergonomics, safety features, and ease of use to embedded development, making it accessible for both hobbyists and professional developers familiar with 🖥 Swift language.

Qt vs. Flutter: Which Framework is Right for Your Embedded Project?

Choosing between Qt and Flutter for embedded project development depends on the specific technical needs of the project.

Qt, built on C++, excels in native performance and efficiency, making it ideal for complex, high-performance applications. It offers extensive libraries and robust community support, catering to projects that require sophisticated functionalities and direct hardware access, such as medical devices and low-end hardware without GPU support.

On the other hand, Flutter focuses on rapid development and cost-effectiveness, utilizing Dart for an accessible programming experience. Key features like hot reload enable quick iteration, and a single codebase ensures consistent UI across platforms.

To sum up, Qt is suited for intricate, performance-critical applications, while Flutter is ideal for projects prioritizing speed, cost-efficiency, and cross-platform consistency.

What happens to the semiconductor industry If China invades Taiwan?

As the tensions in the Asia region continue to grow, the industry analysts are trying to foresee any possible scenario. As such, if China invades Taiwan, the global semiconductor industry would face severe disruptions due to Taiwan's dominance in chip manufacturing. Taiwan produces over 60% of the world's chips and 70% of advanced chips smaller than 7 nanometers.

TSMC, a major Taiwanese company, supplies chips to tech giants like Apple and Google and has started diversifying production to the US, Japan, and Germany to mitigate risks. Nonetheless, any conflict disrupting Taiwan's chip production could cause a global shortage, skyrocketing prices, and significant economic impact.

CrowdStrike Update Highlights the Need for Safer Programming Languages

A global IT outage affecting 8.5 million Windows devices was caused by a faulty update from CrowdStrike, leading to significant disruptions. The issue stemmed from a null pointer bug in the C++ code of the update, which triggered widespread system crashes. Specifically, the program attempted to access memory at an invalid address ("0x000000000000009c"), resulting in a cascade of failures across various critical services and platforms.

Many experts argue that if the update had been written in 🦀 Rust, the compiler would have caught the null pointer bug before deployment, avoiding the widespread disruptions and ensuring safer software deployment practices.

Navigating Elevators: Enhancing Human-Robot Interaction

In NAVER 1784, a study focused on optimizing 📺 robot behaviors in elevators was conducted to improve human satisfaction. It revealed that both politeness and efficiency matter, but time is slightly more critical. Humans perceive robots as slower when they make unnecessary movements, impacting satisfaction even if the actual time taken is the same.

Continuous updates to robots' boarding rules and positions are made to enhance their perceived competence and efficiency. This research highlights the importance of considering human perceptions in Human-Robot Interaction (HRI) to ensure smooth integration of robots in everyday environments.
