🇬🇧 UK is the first country to deploy cybersecurity laws for IoT devices

The UK has recently implemented strict cybersecurity laws for IoT devices, aimed at protecting consumers from cyber threats and reducing cyber crimes. For instance, the new laws prohibit easy passwords like “admin” or “12345” and require manufacturers to ensure robust security measures for internet-connected devices.

This initiative addresses the high vulnerability of smart homes, which can face thousands of hacking attempts weekly. The law also mandates manufacturers to publish policies for reporting security flaws, set minimum periods for security updates, and provide secure software update mechanisms.

☕ Robo-Orders at Naver's Unique Starbucks

At the heart of 🇰🇷 Naver's futuristic 1784 building lies the world’s most unique Starbucks. Located on the second floor, this café features over 100 service robots known as "Rookie." These robots, about three feet tall and resembling water dispensers, are designed to navigate the building effortlessly.

The Rookies use facial recognition technology to identify their intended recipients, ensuring that each order reaches the right person. With animated "eyes" to communicate their movements, these bots interact intuitively with nearby workers, making their presence unobtrusive and efficient.

Employees can place online orders, and baristas prepare the drinks before loading them into the Rookies' storage compartments. These self-driving bots then deliver the beverages directly to meeting rooms and private seats, revolutionizing the traditional café experience.

🚥 3 tips for using CMake with embedded software

CMake, an open-source and cross-platform tool, allows for efficient control over the software compilation process through platform-independent configuration files, generating native makefiles suitable for any compiler environment. This versatility makes CMake a valuable tool for managing complex build environments.

☑️Use Toolchain Files to Simplify Build Configuration:
➡️Different build types (Debug On-Target, Release On-Target, Simulation, Test, and Code Analysis) need specific configurations.
➡️Toolchain files help manage these variations, facilitating cross-compilation and implementation swaps.
➡️Typically, two toolchain files (host and on-target builds) are sufficient.

☑️Automate Build Commands with Custom Scripts:
➡️Avoid memorizing long CMake commands by encapsulating them in scripts.
➡️Custom scripts simplify the build process and reduce errors.
➡️Scripts can include parameters for toolchain files, build types, and other settings, making them useful in CI/CD systems.

☑️Pair CMake with Ninja for Faster Builds:
➡️Ninja is a high-speed build system focused on efficiency.
➡️Using Ninja with CMake can result in x4 to x6 times faster compilation times compared to traditional tools like Make.
➡️Simple setup commands integrate Ninja into the build process, significantly reducing build times and improving development efficiency.

Implementing these tips can streamline the build process for embedded software, making development faster, more efficient, and better suited to modern development practices.
