🎮 Why this matters Running games via Steam on Linux often feels like “dancing with a tambourine”: different engines need different flags, AMD and NVIDIA require different environment variables, and tools like Gamescope and MangoHud must be manually inserted into launch commands. Solution: steamscope.sh - a wrapper script that: ✅ Auto-detects GPU (AMD/NVIDIA) and applies appropriate optimizations ✅ Supports engine-specific flags: Source, Unreal, Unity ✅ Integrates Gamescope, Gamemode, MangoHud, FSR in one command ✅ Works as %command% in Steam launch options ✅ Doesn’t break standard launch - everything is optional 💡 The script doesn’t replace Proton or Steam - it makes their work predictable and configurable. ...

Sometimes you need to run an app on NixOS that’s only available for Ubuntu/Debian or ships as .deb/.iso. Distrobox lets you run it in a container with host integration - like a native app. 💡 Works on any distro with Nix installed. 📦 Create container # Create container with necessary volume mounts nix shell nixpkgs#distrobox --command distrobox create \ --image ubuntu:20.04 \ --name <container-name> \ --volume "<volume_pts>:/dev/pts" \ --volume "<volume_journal>:/var/log/journal" \ --home "$HOME/<container-name>-home" Parameters: ...

OrangePI and other ARM single-board computers often use eMMC or SD cards with limited write endurance. Over time, storage fills up, degrades, or fails. This guide describes a method for data recovery and migration to external storage (USB SSD/HDD) via a chroot environment. 💡 Method is universal: works for OrangePI, Raspberry Pi, NanoPi, and other ARM systems. 📦 Preparation Requirements Component Requirements USB drive SSD/HDD, capacity ≥ eMMC data Live image Any Linux with ARM support (optional) Access root or sudo, physical access to board Network Ethernet or WiFi (for remote access) Check connected storage # Show all MMC devices (eMMC, SD card) ls /dev/mmc* # Show all block devices lsblk # Show partitions and mount points df -h Expected output: ...

WSL (Windows Subsystem for Linux) lets you run native Linux command-line tools directly on Windows - no VM, no dual boot. WSL1 - syscall translation layer (fast, but not 100% compatible) WSL2 - real Linux kernel in lightweight virtualization (full compatibility, slightly more resources) 💡 Use WSL2. Near-native performance with full Docker, systemd, and Linux feature support. Requirements OS: Windows 10 (2004+, build 19041+) or Windows 11 Architecture: x64 or ARM64 Privileges: Administrator (for install) Virtualization: Enabled in BIOS/UEFI (Hyper-V Platform) Check virtualization: ...
