✅ How to Disable MySQL Password Validation on Ubuntu 25.04

#disable mysql password validation #mysql weak password support #uninstall validate_password plugin #mysql allow simple passwords #turn off mysql password policy #mysql 8 disable password check #ubuntu mysql weak password setup #mysql local development password policy #mysql create user without strong password #mysql validate_password component

MySQL 8+ includes a password validation plugin (validate_password) that enforces strong password rules by default. If you're working in a local development environment and want to disable this feature to allow simpler passwords (e.g., password, 123456), follow this safe step-by-step tutorial.

🔧 Step 1: Log into MySQL as Root

sudo mysql

🔧 Step 2: Uninstall the Password Validation Component

Run the following command in the MySQL prompt:

UNINSTALL COMPONENT 'file://component_validate_password';

If successful, you'll see:

Query OK, 0 rows affected

🔧 Step 3: Confirm That Validation Is Disabled

Check that the validation system is gone:

SHOW VARIABLES LIKE 'validate_password%';

If disabled, this will return an empty result set.

🔧 Step 4: Create a User with a Simple Password (Test)

Now that validation is disabled, try creating a user with a weak password:

CREATE USER 'devuser'@'localhost' IDENTIFIED BY '123';
GRANT ALL PRIVILEGES ON *.* TO 'devuser'@'localhost';
FLUSH PRIVILEGES;

This should now work without any errors.

↺ Optional: Re-enable Validation Later

If you want to bring back strong password policies:

INSTALL COMPONENT 'file://component_validate_password';

Then you'll need to restart MySQL:

sudo systemctl restart mysql

Building Micro-Frontends with Webpack Module Federation (2025 Guide)

Let’s say you’re building a dashboard app in React, but your analytics module is handled by another team using Vue. You don’t want to tightly couple the two.

With Webpack Module Federation, you can load the Vue-based analytics micro-frontend into the React host — all without bundling it directly.

State Management Beyond Redux: Using Zustand for Scalable React Apps

  • Project Size: For small to medium-sized projects, Zustand's simplicity can accelerate development.
  • Team Experience: Teams new to state management may find Zustand's learning curve more approachable.
  • Boilerplate Reduction: If minimizing boilerplate is a priority, Zustand offers a cleaner setup.
  • Performance Needs: Zustand's selective rendering can enhance performance in applications with frequent state updates.

However, for large-scale applications requiring complex state interactions, middleware, and extensive tooling, Redux might still be the preferred choice.

Mastering React Rendering Performance with Memoization and Context

Passing functions as props can cause child components to re-render unnecessarily because functions are recreated on every render. The useCallback hook memoizes functions, ensuring they maintain the same reference unless their dependencies change.([React][4])

import React, { useState, useCallback } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  const increment = useCallback(() => setCount(c => c + 1), []);
  const decrement = useCallback(() => setCount(c => c - 1), []);

  return (
    <div>
      <button onClick={increment}>+</button>
      <span>{count}</span>
      <button onClick={decrement}>-</button>
    </div>
  );

Avoiding Memory Leaks in C++ Without Smart Pointers

  video.hide();

  // Load the pre-trained COCO-SSD model
  cocoSsd.load().then(model => {
    detector = model;
    console.log("Model Loaded!");
    // Begin detecting objects every frame
    detectObjects();
  });
}

function detectObjects() {
  detector.detect(video.elt).then(results => {
    detections = results;
