Roons is a mechanical computer kit designed for educational purposes. It lets users build a functioning computer using physical levers, gears, and logic gates, providing a tangible, hands-on experience of how computation works at a fundamental level. The kit includes all necessary parts and instructions, allowing builders to create a simple, programmable machine capable of performing basic calculations and logic operations. The goal is to demystify computing by demonstrating the core principles of logic and automation through a physical, manipulable system.
Driven by a desire for a more engaging and hands-on learning experience for Docker and Kubernetes, the author created iximiuz-labs. This platform uses a "firecracker-powered" approach, meaning it leverages lightweight virtual machines to provide isolated environments for each student. This allows users to experiment freely with container orchestration without risk, while also experiencing the realistic feel of managing real infrastructure. The platform's development journey involved overcoming challenges related to infrastructure automation, cost optimization, and content creation, resulting in a unique and effective way to learn complex cloud-native technologies.
HN commenters generally praised the author's technical choices, particularly using Firecracker microVMs for providing isolated environments for students. Several appreciated the focus on practical, hands-on learning and the platform's potential to offer a more engaging and effective learning experience than traditional methods. Some questioned the long-term business viability, citing potential scaling challenges and competition from existing platforms. Others offered suggestions, including exploring WebAssembly for even lighter-weight environments, incorporating more visual learning aids, and offering a free tier to attract users. One commenter questioned the effectiveness of Firecracker for simple tasks, suggesting Docker in Docker might be sufficient. The platform's pricing structure also drew some scrutiny, with some finding it relatively expensive.
Facing a shortage of skilled tradespeople and a growing recognition of the value of hands-on learning, high schools across the U.S. are reviving shop classes. These modernized programs, often incorporating advanced technologies like robotics and 3D printing alongside traditional woodworking and metalworking, aim to equip students with practical skills applicable to various industries. The resurgence is driven by employer demand, student interest in alternatives to college, and a desire to foster problem-solving abilities and critical thinking. These revamped shop classes offer pathways to well-paying jobs directly after graduation or provide a foundation for further technical education.
Hacker News users generally lauded the return of shop class, citing the value of hands-on learning, problem-solving skills, and exposure to trades. Several commenters shared personal anecdotes about how shop class positively influenced their career paths, even if they didn't pursue a trade directly. Some expressed concern about the cost and difficulty of implementing these programs effectively, including the need for qualified instructors and adequate safety measures. The importance of incorporating modern technology like CAD and 3D printing into shop curriculum was also discussed. A few commenters cautioned against viewing shop class as a solution for all students, emphasizing the need for diverse educational pathways. There was also some discussion of the societal shift away from valuing vocational skills and how its resurgence could address the current skilled labor shortage.
