Rethinking Computer Science Education: Why Students Should Build Before They Master Theory
This story was originally published on HackerNoon at: https://hackernoon.com/rethinking-computer-science-education-why-students-should-build-before-they-master-theory. Computer science students learn theory before building real software. In the AI era, should we reverse the curriculum and teach through practical experience? Check more stories related to machine-learning at: https://hackernoon.com/c/machine-learning. You can also check exclusive content about #ai-in-education, #computer-science-education, #ai-coding-assistants, #software-engineering-education, #project-based-learning, #ai-assisted-programming, #computer-science-fundamentals, #learning-to-code, and more. This story was written by: @sashaapartsin. Learn more about this writer by checking @sashaapartsin's about page, and for more stories, please visit hackernoon.com. Computer science education is outdated, prioritizing foundational knowledge over practical skills, whereas the industry demands hands-on experience with modern tools and technologies. By flipping the order, teaching students to build useful software first and then introducing deeper computer science concepts, educators can better prepare students for the demands of the job market.

Open-Sourcing All Day AI: The Playbook for a 12,000+ Attendee Conference
This story was originally published on HackerNoon at: https://hackernoon.com/open-sourcing-all-day-ai-the-playbook-for-a-12000-attendee-conference. How we built All Day AI, a free 16-hour online AI event, in two months: 12,313 registrants, 140 speakers, a $5 website, and the AI agents behind speaker ops.

We pulled it together in about two months, saw 12,313 participants and 140 speakers, and people stayed and watched for an average of more than 6 hours. An event of this scale doesn’t come together that fast without some serious sprinting, trial and error, and audible-calling. Plenty of people have asked how we did it, so this article open-sources the whole playbook: the goals, the team, the tools, the timeline, and the parts we’d change.

Immutable Architecture: Why the Future of AI Models Demands Permanent Storage
This story was originally published on HackerNoon at: https://hackernoon.com/immutable-architecture-why-the-future-of-ai-models-demands-permanent-storage.

This story was written by: @vishwagw. Learn more about this writer by checking @vishwagw's about page, and for more stories, please visit hackernoon.com. Autonomous driving is increasingly powered by learned models rather than traditional rule-heavy software pipelines. Drawing on developments at Tesla, Wayve, Waymo, and NVIDIA, this article examines the trade-offs between end-to-end learning and modular systems, the difficulty of debugging neural drivers, and the role of simulation, independent safety controls, and regulatory evidence. The author's central argument is that the industry must now prove these systems are safe, not simply demonstrate that they can drive.
