OS

Coding agents use different project memory files like AGENTS.md, CLAUDE.md, and GEMINI.md. Symlinks let them share one source of truth.

Set up a proxy for Git operations, both for HTTP/HTTPS and SSH connections.

Move an installed WSL distribution to another drive by exporting, unregistering, importing, and restoring the default user.

File system basics, directory management with FCBs and inodes, file sharing via hard and symbolic links, physical file structures, and free space management.

I/O controllers, channels, and control modes (polling, interrupt, DMA); device data structures; disk scheduling (FCFS, SSTF, SCAN, CSCAN); buffering.

Causes and necessary conditions of deadlock, plus prevention, avoidance, detection, and recovery, including the Banker's Algorithm.

Levels of processor scheduling, scheduling queue models and criteria, scheduling algorithms, and real-time scheduling.

Notes on process scheduling triggers, evaluation metrics, and common algorithms such as FCFS, SJF, RR, MLFQ, EDF, and LLF.

Threads as the basic unit of scheduling, thread control, synchronization with mutexes, condition variables, and semaphores, and ULT vs KLT.

Types of IPC: shared memory, pipes, message-passing systems, mailboxes, and client-server mechanisms like sockets and RPC.

Notes on concurrency, parallelism, CPU cores, hardware threads, processes, and threads in operating systems.

Process synchronization in operating systems, covering critical sections, semaphores, hardware synchronization, and classic synchronization problems.

OS process management: precedence graphs and program execution, process description, and process control.

An introduction to processes and threads
