Hacker Tutorials is a catalog of project-based learning paths assembled from tutorials that Hacker News users repeatedly upvoted. Rather than presenting one tutorial at a time, each course sequences material for learning and preserves the community’s scores and criticism. The catalog reports 226 tutorials, 2,425 Hacker News submissions and 192,205 points, covering 2007-2026. Its premise is that learners can build substantial systems from scratch by following an ordered path through proven, community-discussed material.
Eleven paths cover databases; interpreters and compilers; neural networks and GPT; operating systems; networking and protocols; developer tools; graphics and GPU programming; browsers and UI frameworks; cryptography and attacks; distributed systems; and software security. The projects are concrete and progressively ambitious: for example, the database path reaches B+ trees, crash recovery, transactions and a small SQL layer, while the networking path goes from raw-socket HTTP to DNS, TCP/IP, TLS and BitTorrent. The distributed-systems course combines implementations of Raft, Paxos and CRDTs with failure testing and formal specification. Each path lists its number of tutorials, Hacker News submissions and summed points; the displayed score distribution reflects popularity, not the recommended learning order. The catalog also offers email updates when courses or stages are added.

Awake is a Git-friendly API client designed to keep API work in version control and support team collaboration. The open-source project describes itself as Git-native and supports REST and OpenAPI workflows. (github.com)
Mission-critical C++ teams are reducing junior hiring while demanding senior-level skills, risking a future shortage of experienced engineers. Mentorship and code review build expertise that automated tools cannot replace. (news.ycombinator.com)
Shellport is an iPhone app for SSH and Mosh terminals, remote file management, server and service dashboards, and database queries. It requires no server agent or account and includes on-device keys, VPN tunnels, and port forwarding; the app is still in development. (shellport.app)
Delta treats AI threads as collaborative documents, letting users annotate prompts, agent responses, tool calls, and code. Its team built a custom editor because live, changing interface elements made the indexes in a conventional code-editor design unreliable. (delta.dev)
Quack adds a client-server protocol to DuckDB, and Ramona C. Truta tests the network overhead with a reproducible SQL benchmarking lab. The experiments use cold runs, repeated measurements, and verifiable result capsules. (ramonactruta.substack.com)
AI-generated code has made it easy to add features, but the growing number of user flows has created tangled behavior, missed edge cases, and UI bugs. The developer asks how to keep the codebase coherent and maintain quality when coding with AI agents. (news.ycombinator.com)
