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.

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.

Yes, a plain Debian 12 or Fedora Server install on cheap x86 hardware, or a Raspberry Pi 5, makes a better router than most consumer gear. It often beats boxes that cost twice as much. You need two network interfaces, a few config files, and about two hours. The result is a gateway with a real stateful firewall via nftables , proper DNS and DHCP from dnsmasq , and traffic shaping that works through CAKE SQM. Every config is plain text you can track in Git.

Running Home Assistant OS (HAOS) inside a Proxmox VE virtual machine gives you the full, officially supported installation - add-ons, Supervisor, automatic updates - while sharing hardware with other VMs and containers. On a modest Intel N305 mini PC, you can run HAOS alongside Plex, Vaultwarden, Nextcloud, and a WireGuard VPN with room to spare. The entire setup takes under 30 minutes. Download the HAOS QCOW2 image, create a VM in Proxmox, import the disk, boot, and you are up and running.

PipeWire hits sub-10ms recording latency on Linux once you set the quantum (buffer size) to 64 or 128 samples at 48 kHz. You also need real-time scheduling for your user, through the rtkit service or an audio group with PAM limits. Most “PipeWire doesn’t work” complaints trace back to broken ALSA UCM profiles, Bluetooth codec fallbacks, or WirePlumber rules that quietly override your audio routing. This guide covers every layer of the stack, from PipeWire’s design down to ALSA period sizes, so you can stop guessing.

The three best ergonomic split keyboards for programmers in 2026 are the MoErgo Glove80 ($399, best overall comfort with contoured key wells and aggressive tenting), the ZSA Voyager ($365, best portable option with a low-profile design and magnetic tenting legs), and the Kinesis Advantage360 Pro ($499, best for deep key well fans with wireless ZMK firmware). All three offer full Linux support, open-source firmware tweaks, and columnar stagger layouts that cut finger strain on long coding days.
