GDB and LLDB are the two workhorses of compiled-language debugging. If you write C, C++, or Rust, knowing these tools saves you hours of staring at printf output. GDB 17.1 is the default debugger on Linux. LLDB 22.1 ships with the LLVM toolchain and is the default on macOS. Both handle Rust binaries through rustc’s DWARF debug info. This guide covers the commands and workflows you actually need: from your first breakpoint to a segfault from a core dump.

Redis Streams give you a light, self-hosted option versus Apache Kafka for event-driven data pipelines. You get append-only log semantics, consumer groups with ack tracking, and sub-millisecond latency on a single Redis 7.4+ instance. Producers XADD events to a stream. Consumer groups read with XREADGROUP in Python via redis-py . Manual XACK calls plus a pending entry list (PEL) give you at-least-once processing.

What follows covers stream basics, consumer groups with failure recovery, a full producer and consumer pipeline with a dead-letter queue, and the ops practices to keep Redis Streams healthy in production.

If you are building a home lab in 2026, the most consequential decision you will make is what hardware to run it on. Rack servers are loud, power-hungry, and overkill for most people. A Raspberry Pi cluster is fun but constrained. The sweet spot - and has been for the last couple of years - is the mini PC.

The market has matured. You now have three distinct tiers worth considering: Intel N150 machines for single-purpose appliances, Intel N305 machines for general-purpose home labs, and AMD Ryzen AI class mini PCs for heavy virtualization or local AI inference. Each tier makes sense for a different type of user, and the wrong pick will either leave you frustrated with underpowered hardware or paying for capabilities you will never use.

Pydantic v3 shipped in late 2025. It has a new Rust-backed core and a fresh model system. With FastAPI 0.115+, you get auto request checks, fast JSON output, and OpenAPI 3.1 docs. No manual schema work. Data errors get caught at the API edge. Client SDKs come from the live spec. The check overhead that used to be a bottleneck is now mostly gone.

This guide walks through what changed in v3, how to lay out a production project, the validation patterns to know, and what deployment looks like when you care about speed.

git worktree lets you check out multiple branches of the same repository simultaneously into separate directories - no stashing, no cloning, no context switching overhead. Each worktree shares the same .git object store, so you get independent working trees instantly without re-downloading any history. Run git worktree add ../my-repo-hotfix hotfix/urgent-fix and you have a fully functional working tree on a separate branch, ready to build and test while your feature branch stays untouched in the original directory.

Deploy at least two Thread border routers and connect them to the same Thread network. Each can be an Apple HomePod Mini, a Google Nest Hub (2nd gen), or a DIY OpenThread Border Router (OTBR) on a Raspberry Pi. This gives your Matter -compatible smart locks, sensors, and lights a reliable IPv6 path to your IP network. They can then talk to Home Assistant , Apple Home, and Google Home at once through Matter’s multi-admin feature. Two routers is the minimum for any network you depend on. If one goes down, the other keeps your mesh alive.
