Bypass Windows 11 Upgrade Assistant / PC Health Check / TPM and CPU Settings

To bypass the Windows 11 Upgrade Assistant and avoid the TPM and CPU requirement checks, you can modify specific registry values to trick the system into thinking your computer meets the necessary requirements. This method addresses common error messages, such as:

How to set up a basic Sinatra + React webapp in 2025

Let's say you want to use Ruby for the backend of a basic webapp but React on the frontend. Here's how.

(Note: All tested on January 13, 2025 with Ruby 3.3, Sinatra 4.1.1, and React 18.3. Configs may change over time.)

First, create the app folder and set up Sinatra:

mkdir my-sinatra-react-app

	@PHONY: test

	test:
	$(eval TMP := $(shell mktemp -d))
	go build -o $(TMP)/toolexec-example.run toolexec-example.go
	go build -a -toolexec=$(TMP)/toolexec-example.run -o hello main.go
	./hello && go clean
	rm -rf $(TMP)

	REVOKE ALL ON DATABASE demo_database FROM demo_user;
	GRANT CONNECT ON DATABASE demo_database TO demo_user;
	GRANT USAGE, CREATE ON SCHEMA public TO demo_user;
	GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO demo_user;
	GRANT USAGE ON ALL SEQUENCES IN SCHEMA public TO demo_user;
	ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO demo_user;
	ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT USAGE ON SEQUENCES TO demo_user;

	#include <windows.h>

	rl_log :: proc "c" (logLevel: rl.TraceLogLevel, text: cstring, args: libc.va_list) {
	context = runtime.default_context()
	context.logger = logger

	level: log.Level
	switch logLevel {
	case .TRACE, .DEBUG: level = .Debug
	case .ALL, .NONE, .INFO: level = .Info
