what is the best way to get safer/more anonymous online

Ok, security and anonymity are not the same thing, but when you combine them you can enhance your online privacy.

My question is: how tech literate are you and what is your aim? As in do you live in a country where your government would benefit from monitoring private (political) conversations or do you just want to degoogle? Because the latter is much easier for the average user.

Some general advice:

Leave Windows and Mac operating systems and switch to Linux distributions like Fedora and Ubuntu (both very user friendly). Switch from Microsoft Office or Pages/Numbers/Keynote (Mac) to LibreOffice.

You want to go more hardcore with a very privacy-focused operating system? There are Whonix and Tails (portable operating system).

Try to replace all your closed source apps with open source ones.

Now, when it comes to browsers, leave Chrome behind. Switch to Firefox (or Firefox Focus if you're on mobile). Want to go a step further? Use LibreWolf (a modified version of Firefox that increases protection against tracking), Brave (good for beginners but it has its controversies), DuckDuckGo or Bromite. You like ecofriendly alternatives? Check Ecosia out.

Are you, like, a journalist or political activist? Then you probably know Tor and other anonymous networks like i2p, freenet, Lokinet, Retroshare, IPFS and GNUnet.

For whistleblowers there are tools like SecureDrop (requires Tor), GlobaLeaks (alternative to SecureDrop), Haven (Android) and OnionShare.

Search engines?

There are Startpage (obtains Google's results but with more privacy), MetaGer (open source), DuckDuckGo (partially open source), Searx (open source). You can see the comparisons here.

Check libRedirect out. It redirects requests from popular socmed websites to privacy friendly frontends.

Alternatives to YouTube that value your privacy? Odysee, PeerTube and DTube.

Decentralized apps and social media? Mastodon (Twitter alternative), Friendica (Facebook alternative), diaspora* (Google+ RIP), PixelFed (Insta alternative), Aether (Reddit alternative).

Messaging?

I know we all use shit like Viber, Messenger, Telegram, Whatsup, Discord etc. but there are:

Signal (feels like Whatsup but it's secure and has end-to-end encryption)

Session (doesn't even require a phone or e-mail address to sign up)

Status (no phone or e-mail address again)

Threema (for mobile)

Delta Chat (you can chat with people if you know their e-mail without them having to use the app)

Team chatting?

Open source options:

Element (an alternative to Discord)

Rocket.chat (good for companies)

Revolt.chat (good for gamers and a good alternative to Discord)

Video/voice messaging?

Brave Talk (the one who creates the talk needs to use the browser but the others can join from any browser)

Jami

Linphone

Jitsi (no account required, video conferencing)

Then for Tor there are various options like Briar (good for activists), Speek! and Cwtch (user friendly).

Georestrictions? You don't want your Internet Provider to see what exactly what you're doing online?

As long as it's legal in your country, then you need to hide your IP with a VPN (authoritarian regimes tend to make them illegal for a reason), preferably one that has a no log policy, RAM servers, does not operate in one of the 14 eyes, supports OpenVPN (protocol), accepts cash payment and uses a strong encryption.

NordVPN (based in Panama)

ProtonVPN (Switzerland)

Cyberghost

Mullvad (Sweden)

Surfshark (Netherlands)

Private e-mails?

ProtonMail

StartMail

Tutamail

Mailbox (ecofriendly option)

Want to hide your real e-mail address to avoid spam etc.? SimpleLogin (open source)

E-mail clients?

Thunderbird

Canary Mail (for Android and iOS)

K-9 Mail (Android)

Too many complex passwords that you can't remember?

NordPass

BitWarden

LessPass

KeePassXC

Two Factor Authenticators?

2FAS

ente Authenticator

Aegis Authenticator

andOTP

Tofu (for iOS)

Want to encrypt your files? VeraCrypt (for your disk), GNU Privacy Guard (for your e-mail), Hat.sh (encryption in your browser), Picocrypt (Desktop encryption).

Want to encrypt your Dropbox, Google Drive etc.? Cryptomator.

Encrypted cloud storage?

NordLocker

MEGA

Proton Drive

Nextcloud

Filen

Encrypted photography storage?

ente

Cryptee

Piwigo

Want to remove metadata from your images and videos? ExifCleaner. For Android? ExifEraser. For iOS? Metapho.

Cloak your images to counter facial recognition? Fawkes.

Encrypted file sharing? Send.

Do you menstruate? Do you want an app that tracks your menstrual cycle but doesn't collect your data? drip.

What about your sexual health? Euki.

Want a fitness tracker without a closed source app and the need to transmit your personal data to the company's servers? Gadgetbridge.

5 Things I Didn’t Expect When Testing My First VR Porn Site

When I first dipped into VR porn, it was pure curiosity. I’d been working in tech — frontend, UX — and I’d been playing with VR for a while, but mostly games and some experimental art stuff. I stumbled across a few adult VR titles and thought: “Huh. I wonder what this is actually like to use, not just to watch.”

What started as a side curiosity quickly turned into hours of testing — and a realization that this is a weird, fascinating medium with its own quirks. If you’re new to this space, here are five things I didn’t expect when I tested my first VR porn site:

1. The importance of comfort (physical and mental) I went in thinking “I’ll just throw on the headset and dive in.” Nope. VR porn isn’t like passive video — you move, you shift, you react. Headset comfort, body positioning, and even room temperature suddenly mattered. If you’re not physically comfortable, it breaks immersion fast.

2. How bad some user interfaces really are As a UX tester, I was floored. Many VR porn platforms still feel like afterthoughts — clunky menus, weird navigation, settings buried in odd places. It’s improving, but if you’ve been spoiled by polished UX elsewhere, prepare to lower expectations (for now).

3. Eye strain is real Spending 30–40 minutes inside a headset watching adult content is very different from gaming. There’s more focus on close-up scenes and less dynamic movement, which can strain your eyes faster than you think. Taking breaks isn’t just good — it’s necessary.

4. How variable video quality can be I assumed “4K” meant “crystal clear.” In VR, resolution isn’t everything — camera angles, lighting, encoding, and player optimization all impact clarity. Some “lower-res” scenes felt more immersive than “ultra-HD” ones. It’s more about how the scene is built for VR than raw specs.

5. The emotional weirdness This one surprised me the most. VR porn isn’t just more “intense” — it’s personal. The sense of presence makes some scenes feel unexpectedly intimate, and if you’re not ready for that shift, it can hit harder than you’d expect. I had to recalibrate what I thought “watching porn” even meant.

I don’t regret diving into this world — it’s genuinely fascinating. But knowing these things up front? It would’ve made those first few sessions a lot smoother.

How to Learn Effectively?

(Tips and tricks!)

1. Apply Pomodoro technique, that is, study for 25 minutes and then take rest for 5 minutes. Do not look at your cellphone in this time, rather go, have a walk to refresh your mind. After 4 sessions, take a long break. Or you can modify it according to your convenience, e.g., study for 50 minutes and take rest for 10 minutes. It's okay to study less, but you have to get deeply absorbed into what you're studying.

2. Imagine the topic as you're studying. Use analogy and visualization. For example, "What is API?" Imagine a restaurant where the kitchen is the backend, and where you sit to eat is the frontend, now API is the waiter who takes your order, goes to kitchen and bring you ready food!

3. Take notes as you're learning, then freshly rewrite it in an organized way on your notebook.

4. Don't be afraid of making mistakes. For example, a math or figure drawing requires practice. Now do it without having a look at the solution. You'll make mistakes, but then you'll get to see your weakness, where you need to improve. Practice is boring but it's the most effective way.

5. Try to have at least 8 hours of sleep at night. Sleep helps consolidate memories by strengthening synaptic connections formed during the day, making temporary information more likely to be stored in long-term memory. So, it's a must for effective learning.

6. When you're bored, pick an interesting topic. When you're stuck, skip the topic and move ahead. But don't give up.

7. Study consistently. No matter how little you study, it's better than not studying at all.

"My advice is, never do tomorrow what you can do today. Procrastination is the thief of time." — Charles Dickens

How to Choose the Right Tech Stack for Your Web App in 2025

In this article, you’ll learn how to confidently choose the right tech stack for your web app, avoid common mistakes, and stay future-proof. Whether you're building an MVP or scaling a SaaS platform, we’ll walk through every critical decision.

What Is a Tech Stack? (And Why It Matters More Than Ever)

Let’s not overcomplicate it. A tech stack is the combination of technologies you use to build and run a web app. It includes:

Front-end: What users see (e.g., React, Vue, Angular)

Back-end: What makes things work behind the scenes (e.g., Node.js, Django, Laravel)

Databases: Where your data lives (e.g., PostgreSQL, MongoDB, MySQL)

DevOps & Hosting: How your app is deployed and scaled (e.g., Docker, AWS, Vercel)

Why it matters: The wrong stack leads to poor performance, higher development costs, and scaling issues. The right stack supports speed, security, scalability, and a better developer experience.

Step 1: Define Your Web App’s Core Purpose

Before choosing tools, define the problem your app solves.

Is it data-heavy like an analytics dashboard?

Real-time focused, like a messaging or collaboration app?

Mobile-first, for customers on the go?

AI-driven, using machine learning in workflows?

Example: If you're building a streaming app, you need a tech stack optimized for media delivery, latency, and concurrent user handling.

Need help defining your app’s vision? Bluell AB’s Web Development service can guide you from idea to architecture.

Step 2: Consider Scalability from Day One

Most startups make the mistake of only thinking about MVP speed. But scaling problems can cost you down the line.

Here’s what to keep in mind:

Stateless architecture supports horizontal scaling

Choose microservices or modular monoliths based on team size and scope

Go for asynchronous processing (e.g., Node.js, Python Celery)

Use CDNs and caching for frontend optimization

A poorly optimized stack can increase infrastructure costs by 30–50% during scale. So, choose a stack that lets you scale without rewriting everything.

Step 3: Think Developer Availability & Community

Great tech means nothing if you can’t find people who can use it well.

Ask yourself:

Are there enough developers skilled in this tech?

Is the community strong and active?

Are there plenty of open-source tools and integrations?

Example: Choosing Go or Elixir might give you performance gains, but hiring developers can be tough compared to React or Node.js ecosystems.

Step 4: Match the Stack with the Right Architecture Pattern

Do you need:

A Monolithic app? Best for MVPs and small teams.

A Microservices architecture? Ideal for large-scale SaaS platforms.

A Serverless model? Great for event-driven apps or unpredictable traffic.

Pro Tip: Don’t over-engineer. Start with a modular monolith, then migrate as you grow.

Step 5: Prioritize Speed and Performance

In 2025, user patience is non-existent. Google says 53% of mobile users leave a page that takes more than 3 seconds to load.

To ensure speed:

Use Next.js or Nuxt.js for server-side rendering

Optimize images and use lazy loading

Use Redis or Memcached for caching

Integrate CDNs like Cloudflare

Benchmark early and often. Use tools like Lighthouse, WebPageTest, and New Relic to monitor.

Step 6: Plan for Integration and APIs

Your app doesn’t live in a vacuum. Think about:

Payment gateways (Stripe, PayPal)

CRM/ERP tools (Salesforce, HubSpot)

3rd-party APIs (OpenAI, Google Maps)

Make sure your stack supports REST or GraphQL seamlessly and has robust middleware for secure integration.

Step 7: Security and Compliance First

Security can’t be an afterthought.

Use stacks that support JWT, OAuth2, and secure sessions

Make sure your database handles encryption-at-rest

Use HTTPS, rate limiting, and sanitize inputs

Data breaches cost startups an average of $3.86 million. Prevention is cheaper than reaction.

Step 8: Don’t Ignore Cost and Licensing

Open source doesn’t always mean free. Some tools have enterprise licenses, usage limits, or require premium add-ons.

Cost checklist:

Licensing (e.g., Firebase becomes costly at scale)

DevOps costs (e.g., AWS vs. DigitalOcean)

Developer productivity (fewer bugs = lower costs)

Budgeting for technology should include time to hire, cost to scale, and infrastructure support.

Step 9: Understand the Role of DevOps and CI/CD

Continuous integration and continuous deployment (CI/CD) aren’t optional anymore.

Choose a tech stack that:

Works well with GitHub Actions, GitLab CI, or Jenkins

Supports containerization with Docker and Kubernetes

Enables fast rollback and testing

This reduces downtime and lets your team iterate faster.

Step 10: Evaluate Real-World Use Cases

Here’s how popular stacks perform:

Look at what companies are using, then adapt, don’t copy blindly.

How Bluell Can Help You Make the Right Tech Choice

Choosing a tech stack isn’t just technical, it’s strategic. Bluell specializes in full-stack development and helps startups and growing companies build modern, scalable web apps. Whether you’re validating an MVP or building a SaaS product from scratch, we can help you pick the right tools from day one.

Conclusion

Think of your tech stack like choosing a foundation for a building. You don’t want to rebuild it when you’re five stories up.

Here’s a quick recap to guide your decision:

Know your app’s purpose

Plan for future growth

Prioritize developer availability and ecosystem

Don’t ignore performance, security, or cost

Lean into CI/CD and DevOps early

Make data-backed decisions, not just trendy ones

Make your tech stack work for your users, your team, and your business, not the other way around.

Introduction

Full-stack JavaScript development now often chooses the MERN stack. Combining MongoDB, Express.js, React.js, and Node.js into one potent stack helps create scalable, dynamic web apps. From social media to SaaS dashboards, developers depend on MERN to easily manage current workloads and ship products faster.

Regarding practical uses, though, speed by itself is insufficient. Not a feature, but rather a baseline need now is secure authentication in MERN stack apps. Even the best app ideas remain vulnerable to attacks, such as session hijacking, token theft, and data exposure, without robust user verification and access control.

This guide focuses on using proven techniques, including JWT authentication, bcrypt-based password hashing, and structured user authorization in MERN to implement a secure login MERN.

Understanding Authorization and Verification

Particularly in MERN stack apps, it is crucial to grasp the differences between authentication and authorization before diving into code.

Verifying the user's identity is the process of authenticity. It addresses the question: Are you indeed who you say you are?

The backend checks the credentials a user logs in with, email and password.

Authorization decides what the user is free to do.  Do you have permission to access this resource?

Once the system identifies you, it looks at what data or actions you might be able to access depending on your roles or permissions.

Developers frequently apply both using JSON Web Tokens (JWTs) in MERN stack authentication. React, the frontend, sends credentials; the backend, Express + Node, checks and generates a signed token. Before granting access to guarded endpoints, MongoDB stores the user's role, which the app verifies.

Typical Security Concerns You Need to Attend 

Ignoring security in MERN applications lets major hazards walk in. Here are some often occurring ones:

Automated bots search for several passwords to access. Brute force attacks. Attacks can, over time, guess credentials without rate limiting or account lockouts.

Should tokens or cookies be mishandled, attackers can pilfer active sessions and pose as users.

Saving plain-text passwords in MongoDB leaves enormous weaknesses. Use bcrypt or another similar method always to hash passwords.

Knowing these risks will help you make sure your application is both safe and functional, whether you intend to hire MERN stack developer or launch a small app. Giving user authorization top priority in MERN apps not only addresses backend issues but also directly helps to maintain user confidence and business reputation.

Setting Up the MERN Stack for Authentication

First of all, you have to know how every component of the MERN stack helps the workflow if you want to apply safe authentication in MERN stack applications. There is a stack comprising:

MongoDB keeps user information, including roles, tokens, and hashed passwords.

Express.js oversees the login, sign-up, and protected access API paths.

React.js uses HTTP requests to interface with the user and interact with the backend.

Node.js ties Express with MongoDB and runs the backend server.

Create a neat framework to prevent code bloat and security leaks before writing the first authentication line. This is a basic project architecture for a MERN authentication system with scalability:

/client

  /src

    /components

    /pages

    /utils

    App.js

    index.js

/server

  /controllers

  /middlewares

  /models

  /routes

  /utils

  config.js

  server.js

How Does The Stack Align For Authentication?

MongoDB defines how user data is kept securely using schemas via Mongoose. Raw passwords are never saved.

Express reveals paths that cause controllers to run logic, including /api/auth/register and /api/auth/login.

React bases on app security requirements stores tokens in memory or localStorage and sends POST requests with credentials.

Sitting between the client and database, Node validates requests and responds securely using JWT tokens.

Keeping roles and permissions managed, you can now start integrating token-based flows, password hashing, and MERN stack authentication logic from this foundation.

Implementing Safe User Registration

Any MERN stack login system starts with user registration. Strong registration shields your app against database compromise, weak passwords, and injection attacks. You have to hash passwords, validate information, and carefully save credentials.

1. Verifying User Commentary

Starting frontend validation with libraries like Yup or React Hook Form. This guarantees a quick response and helps to prevent pointless API calls.

Re-evaluate the same inputs always on the backend. Verify using express-validator or hand-made schema checks:

Email style is correct.

Passwords fulfill minimum complexity (length, symbols, uppercase).

The input contains no hostile scripts.

Never depend just on client-side validation. Validation has to exist server-side to prevent API call bypass.

2. bcrypt-based Hash Password Generation

Store passwords not in plain text but with bcrypt. Salted hashes created by bcrypt make reverse engineering quite challenging.

Javascript

const bcrypt = require('bcryptjs');

const hashedPassword = await bcrypt.hash(req.body.password, 12);

Tip: Use a salt round between 10 and 12 to strike a reasonable mix between performance and security. Store just the hashed output into MongoDB.

3. MongoDB User Credentials Stored

Generate a user Mongoose model. Make sure your schema just takes cleaned, hashed data. This is a basic illustration:

Javascript

const userSchema = new mongoose.Schema({

  email: { type: String, required: true, unique: true },

  password: { type: String, required: true },

  role: { type: String, default: 'user' }

});

MERN apps let one extend this model with timestamps, verification tokens, or user authorization roles. These actions turn your safe login on the MERN stack production-grade one. Sensitive information stays encrypted at rest; registration paths remain under protection.

Implementing Secure Login

Designing a login system that guarantees identity verification without revealing user information comes next in MERN stack authentication, following secure registration. JSON Web Tokens (JWT), HTTP-only cookies, and common attack defenses all come into play here.

Check with JWT authentically

Create a JWT on the backend when a user logs in with legitimate credentials. Signed with a secret key, this token bears encoded user information. This is a fundamental flow:

Javascript

const token = jwt.sign({ userId: user._id }, process.env.JWT_SECRET, {

  expiresIn: '1d'

});

Send the token in the response body (with care) or return it to the frontend using HTTP-only cookies. Through identification of legitimate sessions, the token helps guard private paths and resources.

Store Tokens Using HTTP-only Cookies

Use HTTP-only cookies instead of local storage, which is vulnerable to XSS attacks JWT storage. Only sent in server requests, this kind of cookie cannot be accessed with JavaScript.

Javascript

res.cookie('token', token, {

  httpOnly: true,

  secure: true,

  sameSite: 'Strict',

  maxAge: 86400000

});

Fight XSS and CSRF Attacks

Shield the MERN app from typical attack paths for safe login. Using these measures guarantees not only functional but also perfect user authorization in MERN applications. When combined with the secure authentication in MERN stack, your login system becomes a strong basis for user and business data protection.

Sanitize all user input, especially form fields and URLs, XSS, Cross-Site Scripting. React or server validation middlewares can be found in libraries like DOMPurify.

Always use cookies, always apply CSRF protection using custom tokens, and sameSite: strict settings. Express apps call for middleware like csurf.

Safeguarding User Information and Routes

Route protection is a must in every secure authentication in MERN stack system. Once a user logs in, middleware in your Express backend must confirm their access to specific endpoints.

Middleware for Routes Protected

Token verifying JWT-based authentication limits access. Add middleware to see whether the token exists and is legitimate.

javascript

const verifyToken = (req, res, next) => {

  const token = req.cookies.token;

  if (!token) return res.status(401).json({ message: 'Unauthorized access' });

  jwt.verify(token, process.env.JWT_SECRET, (err, decoded) => {

    if (err) return res.status(403).json({ message: 'Invalid token' });

    req.user = decoded;

    next();

  });

};

Role-Based Access Control (RBAC)

Authorization goes beyond login. After secure authentication in MERN stack, validate the user’s role to apply role-based access control. For example:

js

const isAdmin = (req, res, next) => {

  if (req.user.role !== 'admin') {

    return res.status(403).json({ message: 'Admin privileges required' });

  }

  next();

};

Real World Case Study

Hiring MERN stack developers to create a product dashboard will mean limiting access depending on user roles. While standard users can only view their data, administrators can oversee users. These guardrails enable responsibility and help to preserve data integrity. Combining route protection with RBAC gives your user authorization in MERN airtight, dependable, and production-ready form.

Ideal MERN Stack Authentication Practices

You have to surpass login forms and tokens to create really secure authentication in MERN stack applications. Your management of your environment, contacts, and code hygiene will determine the foundation.

Guard Environmental Variables

Never hardcode secrets, including JWT keys, database URIs, or API credentials. Store them in a .env file, and dotenv loads them securely. Include .env in to gitignore to prevent leaking secrets into version control.

Js

require('dotenv').config();

const jwtSecret = process.env.JWT_SECRET;

Apply HTTPS and Secure Headers

Every production app runs over HTTPS. Token and sensitive data leaks from unsecured endpoints. Create HTTP headers like:

Tight-Transport-Security X-Content-Type-Choice Options

Policy for Content Security

Clickjacking, content sniffing, and cross-site scripting (XSS) are prevented in part by these headers.

Maintain Dependencies Current

Many well-known weaknesses reside in antiquated packages. Scan for and quickly fix problems using npm audit, Snyk, or GitHub's Dependabot. Manage MERN stack authentication and user sessions, avoiding obsolete libraries.

Bottomline

MERN stack applications now require secure authentication; it is not a choice. It builds trust, safeguards user data, and increases the resilience of your application in manufacturing settings.

Every action counts, from knowing how secure authentication in MERN stack

differs from authorization to configuring JWT-based login, hashing passwords with bcrypt, and safeguarding paths with role-based access control. Maintaining one step ahead of actual threats requires following best practices, including securing environment variables, enforcing HTTPS, and keeping your stack current.

In a world where web breaches are a daily headline, getting secure authentication in MERN stack right means everything. You now know how to structure your project, secure your routes, protect your users, and keep your system airtight from the start!

🔐 Using Keycloak to Manage User Permissions

In modern application architectures—especially those involving microservices, distributed systems, or cloud-native platforms—managing user authentication and authorization can be complex. That’s where Keycloak, an open-source identity and access management solution, shines.

This blog explores how Keycloak simplifies permission management, enhances security, and integrates seamlessly with various applications and systems.

✅ What Is Keycloak?

Keycloak is an open-source tool developed by Red Hat that handles authentication, authorization, single sign-on (SSO), and identity brokering. It allows you to secure applications and services with minimal effort.

Key features include:

Single Sign-On (SSO)

LDAP and Active Directory integration

Social login (Google, Facebook, etc.)

Role-Based Access Control (RBAC)

Multi-factor authentication (MFA)

Fine-grained permission control

🎯 Why Use Keycloak for Managing Permissions?

Keycloak helps teams centralize user management and permissions, reducing the complexity of managing security policies across multiple services. With built-in role-based access control, administrators can grant and revoke permissions easily and consistently.

🔑 Core Concepts

1. Users

Individual accounts that represent human or machine actors in your system.

2. Roles

Roles define sets of permissions. Keycloak supports both realm roles (global) and client roles (application-specific).

3. Groups

Collections of users that can share roles and policies. Ideal for team-level access control.

4. Clients

Applications or services that use Keycloak for login/authentication.

🧩 Managing Permissions in Keycloak

➤ Step 1: Define Roles

Roles are used to categorize permissions. For example:

admin

editor

viewer

You can create roles globally (for the realm) or specifically for a client (an app).

➤ Step 2: Assign Roles to Users or Groups

You can assign roles directly to individual users or to groups for bulk management.

➤ Step 3: Enforce Role-Based Access in Applications

Applications integrated with Keycloak can check user roles in access tokens and allow or deny actions based on those roles.

For example, a frontend app can restrict the visibility of admin settings unless the user has the admin role.

🔄 Integration with Other Systems

Keycloak supports integrations via:

OpenID Connect (OIDC)

SAML 2.0

LDAP/Active Directory

Custom identity providers

This means you can centralize permission control across:

Web apps

APIs

Kubernetes clusters

Cloud platforms

🛡️ Benefits of Using Keycloak for Permissions

✅ Centralized Control: Manage all user roles and permissions from one place

✅ Scalable Architecture: Suitable for small apps or enterprise-grade systems

✅ Security Best Practices: MFA, session control, and token expiration

✅ Open-Source & Extensible: No licensing cost and rich community support

🚀 Final Thoughts

Managing user permissions can be a daunting task—especially across a fleet of applications and environments. Keycloak offers a powerful, centralized, and flexible approach to control access, define roles, and secure your systems.

Whether you’re building a multi-tenant SaaS app or securing internal developer tools, Keycloak helps you deliver secure, scalable authentication and authorization with ease.
