- The author taught project-based programming courses from 2007 to 2026 in week-long immersion formats, but these are no longer scheduled.
- Due to a market collapse in continuing education since 2023, which was their primary income source, the courses ended, impacting their ability to teach into retirement.
- With children going to college and a desire for change, the author is pursuing a Professional Educator's License in Secondary Education instead of continuing with the courses.
Why don't people use Git properly?
a day ago
- The author introduces Arca, an educational project with a landing page, offering early access soon and free slots for donors.
- Git is a crucial version control system widely used in software development, but many people struggle with it, leading to issues like merge conflicts, poor commits, and misuse of repositories.
- The problem stems from inadequate education and experience with git, especially among those who are not in core software roles and lack institutional support or motivation to learn.
- A significant barrier is git's reliance on command-line interfaces, which many developers, especially those on Windows or using IDEs without CLI familiarity, find non-intuitive and difficult to master.
- People often don't understand the problems git solves, such as fast rollbacks, deployment automation, and risk-taking in development, because they lack hands-on experience with projects that require these features.
- The author compares git to Roman armor, explaining that the safety it provides allows developers to take more risks and be more ambitious, but without experiencing this security, users may develop defensive habits and avoid new tools.
- To improve git usage, the author suggests integrating version control early in education and promoting DevOps rotations in companies, but acknowledges the challenges in scaling these solutions.
Trees are mostly made of air and a generalizable lesson for AI safety
a day ago
- Many people engage in activities labeled as 'AI Safety' without a deep conceptual understanding of the basics, which may inadvertently worsen the situation.
- A lack of foundational knowledge, such as instrumental convergence and inner alignment, is common in AI safety education, where focus often shifts to prosaic empirical methods over strategy and fundamentals.
- Understanding basics like 'trees are made out of air' illustrates the importance of foundational knowledge for sample-efficient epistemology, crucial in AI alignment due to sparse rewards.
- AI safety basics are often not internalized or exercised in practice, leading to incoherent answers about existential risks from AI among students and researchers.
- Deep understanding of AI safety fundamentals helps maintain focus and motivation, preventing distractions and fostering meaningful contributions to the field.
