5j9 / Sync-TimeHttpAdaptive.ps1

Created January 25, 2026 20:18

PowerShell high-accuracy time synchronization script using HTTP headers (Google) to bypass restricted or blocked NTP/UDP 123 ports. Developed for system clock recovery during the Iran internet shutdowns of January 2026. Features dynamic outlier trimming and latency compensation.

	# ==============================================================================
	# SCRIPT NOTE:
	# This script was developed to synchronize the system clock during the
	# internet shutdowns in Iran in January 2026. During this period, NTP servers
	# were restricted, and only a limited number of sites (like Google) were
	# accessible. This script uses HTTP headers to bypass those restrictions.
	#
	# ACCURACY NOTE:
	# Standard HTTP 'Date' headers only provide precision to the nearest second.
	# While this script compensates for network latency (RTT/2), the base data

5j9 / Fusion_StickyInput_Buffer.ahk

Created January 25, 2026 19:50

AutoHotkey v2 script for Fusion.exe: Emulates "Sticky Keys" for navigation (ASDQWE/Arrows) to maintain input states during paused frame-advance workflows. Includes a CapsLock toggle and status indicator.

	/*
	================================================================================
	FUSION 3D FRAME-ADVANCE INPUT BUFFER
	================================================================================
	USAGE:
	1. Press [Pause] to halt the simulation/emulation in Fusion.
	2. Toggle [A,S,D,Q,W,E,Arrows] to set the desired movement/action state.
	3. Use the [Insert] key to advance frame-by-frame.
	(The keys will remain "digitally held" thanks to this script).
	4. Toggle [CapsLock] to instantly release all keys and disable sticky mode.

5j9 / Fix-Windows-DisplayPort-Resizing.ps1

Last active January 7, 2026 04:36

Automates the fix for Windows windows resizing/shrinking to the top-left corner after the monitor sleeps. Dynamically detects current resolution and applies it to the "Simulated" and "NOEDID" registry profiles under GraphicsDrivers.

	# Run this script as Administrator to fix the "DisplayPort/Sleep Resizing" bug.
	# It syncs your active resolution with the Windows 'Simulated' fallback profiles.

	# Check for Administrator privileges
	if (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
	Write-Warning "Please run this script as an Administrator!"
	break
	}

	# 1. Get current screen resolution automatically
