Recent versions of ChatGPT, especially the o3 and o4-mini models, often insert invisible Unicode characters—such as zero-width spaces (U+200B), narrow no-break spaces (U+202F), and others—into their replies. These characters are not visible in standard text editors or word processors, but they can be detected and removed using several methods.

Signal, the popular encrypted messaging app, has introduced usernames, a groundbreaking feature that enhances privacy by allowing users to connect without sharing their phone numbers. This update is a game-changer for those who value anonymity and control over their personal information. Here’s everything you need to know.

What Are Signal Usernames?

Usernames are unique identifiers that let you communicate on Signal without revealing your phone number. Instead of sharing your contact details, you can now share a username (e.g., “@YourUsername”), offering a more private way to connect.

Why Do Usernames Matter?

1. Enhanced Privacy: Keep your phone number hidden when connecting with others.
2. Anonymity: Ideal for journalists, activists, or anyone needing discretion.
3. Control: You can change your username anytime and decide who gets access to it.
4. Secure Communication: Signal’s end-to-end encryption ensures conversations remain private.

Do You Still Need a Phone Number for Signal?

Yes, Signal still requires a phone number to sign up and verify your account. However, once registered, usernames allow you to keep your phone number private during interactions. This strikes a balance between initial account setup and ongoing privacy.

How to Set Up Your Username

1. Open the Signal app and go to settings.
2. Tap on the “Username” option.
3. Create a unique username and save it.
4. Share your username instead of your phone number when connecting with others.

Pros and Cons of Using Usernames

Pros

• Protects your phone number from being shared unnecessarily.
• Offers flexibility—you can change usernames anytime.
• Easier to connect in online communities or professional settings.

Cons

• You still need a phone number for initial registration.
• If someone guesses or finds your username, they can contact you (blocking is available).

How to Maximize Privacy With Usernames

1. Use a non-identifiable username for added anonymity.
2. Avoid sharing your phone number unless absolutely necessary.
3. Regularly review Signal’s privacy settings.

Final Thoughts: A Step Toward Better Privacy

Signal’s introduction of usernames is a major leap forward in protecting user privacy, allowing you to communicate securely without exposing personal details like your phone number. While registration still requires a phone number, usernames provide an additional layer of anonymity and control once you’re set up.

Have You Ever Felt This Way Using iOS or MacOS?

• “Ads keep popping up everywhere when I browse the web…”
• “I care about privacy, but which browser is truly safe?”
• “Slow page loads are so frustrating!”

If these sound familiar, you’re not alone. Many users of Apple devices face these issues every day.

Are You Really Satisfied with Your Default Browser?

Most people stick with well-known browsers like Safari or Chrome. But are you truly happy with:

• The overwhelming number of ads and pop-ups?
• Worrying about wasted data and battery drain?
• Not knowing if your privacy is actually protected?

These are common complaints among Apple users.

The Day I Discovered a Surprisingly Smooth Browsing Experience

I, too, used Safari and Chrome for years. But one day, I tried a certain browser—and was honestly shocked by the difference.

• Thanks to a special feature, almost all ads disappeared.
• Pages loaded much faster, and my data usage dropped.
• There were also thoughtful privacy features that gave me real peace of mind.

This experience was so impressive, I had to share it with others.

iCloud’s Advanced Data Protection (ADP) is one of Apple’s most robust security features. By enabling this feature, data stored in iCloud is end-to-end encrypted, ensuring that it can only be decrypted on the user’s trusted devices. This article explains why you should enable ADP and how to set it up.

Why Enable ADP?

1. Complete Privacy Protection
   With ADP enabled, data stored in iCloud (e.g., photos, notes, messages) becomes inaccessible to third parties, including Apple. This significantly reduces the risk of data breaches or unauthorized access.
2. End-to-End Encryption
   ADP ensures that data is encrypted during transmission and remains encrypted at rest. Only trusted devices can decrypt the data, offering a high level of security.
3. Defense Against Security Threats
   In an era of increasing cyberattacks and data breaches, ADP provides a powerful safeguard for personal information.

How to Enable ADP

Requirements

• Devices with iOS 16.2 or later or macOS 13.1 or later.
• Two-factor authentication enabled for your Apple ID.
• Passcodes or passwords set on all devices.
• At least one recovery method (Recovery Contact or Recovery Key).

Steps to Enable ADP

On iPhone or iPad:

1. Open the Settings app.
2. Tap your name and select “iCloud.”
3. Scroll down and tap “Advanced Data Protection.”
4. Select “Turn On Advanced Data Protection” and follow the on-screen instructions.

On Mac:

1. Open “System Settings” from the Apple menu.
2. Click your name and select “iCloud.”
3. Click “Advanced Data Protection” and enable it by following the prompts.

Important Notes

• Enabling ADP disables web access to iCloud.com by default but allows temporary access if needed.
• If no trusted device is available, a Recovery Key will be required to restore access to your data. Store this key securely.
• ADP is not available in certain regions due to local regulations.

Conclusion

iCloud’s Advanced Data Protection is an essential feature for safeguarding personal information and critical data. If you regularly use iCloud, enabling ADP maximizes your security and privacy, ensuring peace of mind in today’s digital landscape.

1. If the shell is slightly open:

• Use your fingernails to wedge into the gap and twist gently to pop it open.
• If it’s hard to do with your nails, you can use a piece of another pistachio shell as a lever — insert it into the gap and twist.

2. If the shell is completely closed:

• Pistachios with completely closed shells are tricky. Avoid forcing them open with your fingers — it can hurt.
• A small nutcracker or pliers can help crack them safely.
• Alternatively, you can wrap the nut in a kitchen towel and give it a gentle tap with something hard (like the back of a spoon), but be careful not to crush the nut inside.

The easiest and safest way is definitely using a piece of another shell to twist open the nut. Give it a try.
