The open-source project 'build-your-own-x', which has amassed 529,000 stars on GitHub, compiles tutorials that teach developers to build core technologies from scratch, aiming to bridge the gap betwee…
A developer built a transformer model from scratch using pure PyTorch, without relying on libraries like HuggingFace, to gain a deeper understanding of the architecture. The project involved implement…
Writing toy software is a joyful and educational practice that helps developers understand systems deeply, according to a 2025 essay. The author argues that building small, non-production programs lik…
AI will not replace human teachers in education, argues a new analysis, because biological responses to human touch, the expression of non-politically-correct ideas, trust-building mechanisms, and sta…
CodeCrafters' 'Build Your Own <X>' repository compiles step-by-step guides for recreating technologies from scratch, covering topics from 3D renderers and AI models to blockchain and web browsers. The…
A skeptical analysis argues that AI enthusiasm may be self-deceptive, citing a late 2025 study finding developers using AI were 19% slower despite feeling faster. The author warns that AI tools are un…
Intelligence can lead to poor decisions as smart people become adept at justifying irrational choices through motivated reasoning. Psychologists find that higher cognitive ability often correlates wit…
A developer proposes a method called 'Named-Persona Adversarial Review' to overcome the blind spots of single-modal LLMs in code review. By asking the AI to review code as specific named individuals w…
A developer built a methodology for turning personal tools into open source contributions and subjected it to a novel AI-assisted review process that role-plays as 24 famous engineers, including Linus…
A developer introduced a prompting pattern based on the Feynman Technique that forces AI models like GPT-4o and Claude to explain any concept at four distinct cognitive levels: for a 5-year-old, a tec…
A senior engineer describes how AI-generated software often builds only a facade that matches metrics but lacks structural integrity, comparing it to a film set or a cargo cult. The piece warns that A…
In the late 1970s, physicist Richard Feynman scribbled a mathematical solution to help a friend decide whether to order a familiar dish or try something new at a Thai restaurant. Berkeley computationa…
FeynRL, an algorithm-first framework for post-training and fine-tuning large models, has been released as an open-source tool supporting supervised fine-tuning, preference learning, and reinforcement …
