BFS, the kit-based C++ API, and the pervasively multithreaded design behind BeOS's open-source successor.
Verify an official Haiku image, test it live in a VM, prepare BFS and firmware boot safely, install, reboot, and validate the result.
Create typed BFS metadata, index it per volume, build and save accurate Tracker queries, and verify live results without losing attributes.
Use Haiku's limited POSIX account tools for services and shell tests while understanding why they do not create separate desktop users.
Build a warning-clean Haiku GUI with BApplication, BWindow, layout-managed controls and BMessage handling, then test its real lifecycle.
Search, install, update and remove Haiku packages safely, audit repositories and package state, and recover without imaginary rollback commands.
Use Haiku Terminal, Bash profiles and native filesystem tools safely, write portable scripts, and separate POSIX habits from Linux assumptions.
Configure WebPositive's real settings, organize file-based bookmarks, control history and cookies, and handle downloads and credentials safely.
A source-grounded map of Haiku's kernel: teams and threads, virtual memory, IPC, scheduling, modules, system calls, drivers, and debugging.
How Haiku's native API is divided into cooperating Kits, with shared conventions for messages, ownership, status codes, linking, and threads.
How Haiku BQuery combines BFS indexes, typed predicates, BMessenger updates, saved searches, and defensive state reconciliation.
