Windows 11 26H2 — In-Place Upgrade Compatibility Helper

A lightweight PowerShell utility for preparing Windows 11 in-place upgrades on unsupported hardware configurations, particularly VMware virtual machines without a virtual TPM.

The script configures several registry-based compatibility overrides used by Windows Setup. It does not modify installation media, patch Setup binaries, emulate TPM hardware or change the virtual machine configuration.

Warning

This is an unofficial compatibility workaround. Microsoft does not support installing Windows 11 on hardware that does not meet its minimum requirements. An upgrade is not guaranteed to succeed, and unsupported devices are not guaranteed to receive updates.

Features

MySQL & MariaDB Backup & Restore Guide

A practical field guide to complete logical backups, parallel dump/load, utf8mb4, and restore validation.

Covers Oracle MySQL tools (mysqldump / mysql and MySQL Shell), MyDumper/MyLoader, and Percona XtraBackup.

Last reviewed: 22 October 2026 · Format: GitHub Gist / Markdown · Scope: Version-dependent MySQL-compatible workflows

Important

A backup is not proven until it has been restored and checked. Test these examples on a staging system first. Only restore SQL files you trust: their statements execute with the privileges of the connected account.

Secure SSH & Automatic Git Signing

GitHub, Gists, GitLab and Arch Linux AUR

A secure, low-maintenance OpenSSH and Git configuration with automatic Ed25519 signing, provider-specific identities, verified host keys, and connection multiplexing.

Target environment: OpenSSH 10.6p1, OpenSSL 3.6.5, modern Git.

Design principles

Reclaiming Space from VMware Workstation VMDKs on a Linux Host with ZFS

Deleting files inside a virtual machine frees space in the guest filesystem, but it does not necessarily release the corresponding storage on the host. A growable VMware virtual disk can therefore remain much larger than the guest's current data usage.

This guide covers zero-filling unused guest filesystem space and compacting a growable VMDK with VMware Workstation Pro on a Linux host. It also explains how ZFS affects the result, with brief compatibility notes for TRIM/UNMAP and ESXi.

Compaction reduces host storage consumption. It does not reduce the virtual disk's configured capacity or resize guest partitions.

Scope and prerequisites

Logitech G502 X Master Configuration & Troubleshooting Guide

The Logitech G502 X features LIGHTFORCE hybrid optical-mechanical switches, a dual-mode scroll wheel, and 13 programmable controls. This guide covers default factory mappings, DPI mechanics, middle-click optimization, software choices, and hardware recovery routines.

VMware VMX Configuration Parameters — Reference

⚠️ USE AT YOUR OWN RISK
Most parameters listed here are undocumented and unsupported by VMware/Broadcom.
Always back up your .vmx file before editing. Test in non-production environments first.
Parameter availability depends on VMware product version, host OS, and virtualHW.version.

	VMware may reorder .vmx assignments when the VM is opened or edited in its GUI.
	This formatter restores a deterministic layout without changing the raw bytes of
	individual values. Existing comments are discarded because, after reordering,
	they cannot reliably be associated with their original assignments.

	By default, each non-empty group has an explanatory heading and is separated
	from the previous group by one blank line. The --no-comments / --compact option
