What Is Black Tea? Comparing Taste, Caffeine, and Benefits

If you’ve ever wondered what is black tea and why millions of people drink it daily, you’re not alone. From tea enthusiasts who collect rare blends, to health-conscious individuals searching for natural wellness, to students exploring culture and history, black tea offers something for everyone. Unlike herbal infusions or coffee, black tea brings together a unique combination of flavor, tradition, and health benefits.
In this guide, you’ll learn what black tea really is, how it’s made, its nutritional value, and why it continues to be one of the world’s most beloved drinks.
What Is Black Tea and How Is It Made?
Black tea is a type of tea made from the leaves of the Camellia sinensis plant. The key difference between black tea and other teas (like green or white) is the oxidation process.
- Step 1: Harvesting – Fresh tea leaves are picked.
- Step 2: Withering – Leaves are spread out to reduce moisture.
- Step 3: Rolling – Leaves are twisted or crushed to release natural enzymes.
- Step 4: Oxidation (Fermentation Process) – Oxygen exposure turns the leaves dark brown or black, creating bold flavor.
- Step 5: Drying & Sorting – Leaves are dried and graded before packaging.
This process is what gives black tea its rich taste, deep color, and higher caffeine compared to green or white teas.
History of Black Tea: From Ancient China to the World
Black tea traces back to 17th-century China, where it was first produced in the Fujian province. Known as “hong cha” (red tea) in Chinese culture, it gained popularity when exported to Europe through trade routes.
- China & India became the two biggest exporters.
- Darjeeling and Assam teas from India are still considered luxury teas worldwide.
- Ceylon tea from Sri Lanka became another global favorite.
Today, black tea is a daily ritual in the UK, Pakistan, India, and beyond.
Black Tea vs Green Tea: What’s the Difference?

Zoom: From Video Meetings to an AI-Driven Collaboration Hub

When the pandemic reshaped the way the world worked, one tool rose to prominence almost overnight: Zoom. What started as a simple video conferencing solution quickly transformed into a global communications powerhouse. Under the leadership of its founder Eric Yuan, the company expanded beyond basic online meetings to deliver a full collaboration suite, complete with webinars, virtual events, and AI-powered features. Today, it’s more than a video call tool—it’s a workplace ecosystem designed to keep teams connected, productive, and secure.

The Rise of a Global Video Conferencing Platform
Zoom Communications, Inc. launched in 2011 with a vision to simplify virtual connections. Its flagship product, Zoom Meetings, was built for seamless video conferencing, and it quickly gained traction because it was easier to use and more reliable than older platforms.
While competitors struggled with complicated interfaces, Zoom made joining a meeting as simple as clicking a link. Features like screen sharing, cloud recording, and live chat helped it stand out. As organizations moved to remote and hybrid models, the platform became the go-to choice for virtual classrooms, corporate meetings, and even family gatherings.
Understanding Zoom Workplace
In recent years, the company has rebranded its offering as Zoom Workplace—an all-in-one platform for modern collaboration. Instead of being seen only as a tool for video calls, the new Workplace concept integrates multiple services under a single interface.
Zoom Workplace includes team chat, a digital whiteboard, scheduling tools, email integration, and even telephony solutions like Zoom Phone. This shift signals the company’s intent to move beyond video conferencing and become a comprehensive hub for enterprise communication.
For businesses, this unified interface reduces the need to juggle multiple apps, creating a more streamlined workflow for hybrid teams.
AI Companion: Redefining Smart Meetings
One of the most exciting innovations from Zoom is its AI Companion. This intelligent assistant enhances meetings by automatically generating summaries, drafting follow-up tasks, and answering questions in natural language. Users can even “Ask AI” to catch them up on what they missed during a call.
These AI-driven features highlight the company’s evolution from a video-first tool to an AI-first work platform. By embedding artificial intelligence into everyday workflows, Zoom ensures teams spend less time on administrative tasks and more time collaborating effectively.
Key Features That Drive Adoption

Few companies have had such a direct influence on modern work culture. From Fortune 500 companies to small classrooms, Zoom became synonymous with remote collaboration. Universities adopted it for online lectures, while global corporations used it to manage distributed teams.
Its impact went beyond business—it became a household name. Families used it for weddings, birthdays, and reunions, making the brand part of everyday life. Even as restrictions eased, hybrid work ensured that its role remained central to how people connect.
Challenges and the Road Ahead
Despite its success, Zoom faces competition from giants like Microsoft Teams, Google Meet, and Cisco Webex. These platforms also bundle chat, storage, and productivity tools, creating a tough marketplace.

Zoom’s strategy of positioning itself as an AI-first communications platform may be the differentiator. By leaning into features like AI Companion and Zoom Workplace, it can attract organizations seeking smart, integrated, and flexible solutions.

Wallpapoz: The Ultimate GNOME Wallpaper Manager for Dynamic Desktop Customization

Personalizing a Linux desktop has always been one of the most appealing aspects of open-source environments, and one tool that makes this even more engaging is Wallpapoz. This open-source wallpaper manager is designed for GNOME and XFCE desktop environments, allowing users to go far beyond static backgrounds. Instead of being stuck with one picture across all workspaces, Wallpapoz lets you assign different images to specific desktops or even rotate them on a time-based schedule. By combining a simple configuration interface with a powerful wallpaper daemon, it has become a favorite among users who love to experiment with desktop customization.
Wallpapoz is more than just a wallpaper changer—it’s a full-featured desktop customization utility that operates with dynamic flexibility. The core idea is simple: whenever you switch between workspaces in GNOME or XFCE, your background can change with it. This creates an immersive experience where each workspace has its own personality. For example, you might assign a productivity-themed wallpaper for your coding environment, a calm landscape for your writing desk, and a motivational quote for your study setup.
In addition to workspace-specific customization, Wallpapoz also supports time-based wallpaper switching. This means that your desktop background can update automatically according to intervals you set—whether that’s every few minutes, hourly, or once per day. Many users describe this as refreshing because it keeps their workspace visually stimulating without any manual effort.
Core Features of Wallpapoz
The strength of Wallpapoz lies in its lightweight but flexible design. Its architecture is built on Python and PyGtk, with image handling provided by the Python Imaging Library (PIL). This ensures compatibility across most Linux distributions without needing heavy additional dependencies.
Some of its standout features include:
- Workspace-Specific Wallpapers: Customize each GNOME or XFCE workspace with its own group of wallpapers.
- Time-Based Rotation: Automatically switch wallpapers at set intervals for variety.
- Configuration GUI: A user-friendly graphical tool makes it easy to assign images and create groups.
- Daemon Process: The daemon_wallpapoz service runs in the background, handling wallpaper changes seamlessly as you move between workspaces.
- Lightweight and Open Source: As a free and open-source utility, it’s easy to install, modify, and extend.
These features make Wallpapoz especially useful for users who enjoy both automation and customization in their desktop experience.
Installing Wallpapoz on Linux
Getting Wallpapoz up and running is fairly straightforward, especially if you’re comfortable with basic Linux tools. Since it’s an open-source utility, the source code is available on GitHub and other repositories.
To install, you’ll first need to ensure you have the necessary dependencies: Python, PyGtk, and PIL. Most modern distributions include these in their package managers. After resolving dependencies, you can download the source code, run the setup.py
installation script, and configure it for your system.
On some distributions, you may also find pre-built packages that simplify the process. Once installed, you’ll have access to both the configuration tool and the daemon, which together form the heart of the application.
Configuring Wallpapers with the GUI
The configuration process is managed through the Wallpapoz GUI program, which provides a straightforward way to set up wallpaper groups. Users can assign specific images or directories to each workspace, creating a unique theme for every environment. The GUI also includes options for time-based switching, where you can specify the interval between wallpaper changes.
This setup allows for endless customization. For example, you could create a “morning” group of bright wallpapers to help you wake up, an “afternoon” group of neutral colors for focus, and an “evening” group of darker tones for a relaxed mood. Since the configuration file is stored in XML format, advanced users can also edit it manually for fine-tuned control.
Running daemon_wallpapoz in the Background
The real power of Wallpapoz comes from the daemon_wallpapoz service. Once activated, it automatically handles wallpaper transitions based on your workspace switches or time-based settings. This means you don’t need to restart the application each time—it quietly runs in the background, keeping your desktop environment visually dynamic.
To ensure it launches automatically on startup, you can integrate the daemon into your GNOME or XFCE session settings. This way, your wallpapers will always load according to your preferences without requiring manual setup after every reboot.
Common Issues and Troubleshooting
Like many open-source utilities, Wallpapoz can occasionally run into conflicts. One of the most common issues occurs when GNOME session wallpaper settings override those of daemon_wallpapoz, causing backgrounds to reset after logout or reboot. The solution is typically to disable conflicting GNOME wallpaper daemons or adjust startup order so that Wallpapoz runs after the desktop loads.z
Why Use Wallpapoz Instead of Alternatives?
There are other wallpaper changers available for Linux, but most lack the level of control that Wallpapoz provides. Basic wallpaper tools can rotate backgrounds, but they don’t offer workspace-specific customization. Similarly, some XFCE plugins allow rotation, but they don’t provide the same automation or background daemon service.
By combining simplicity with depth, Wallpapoz stands out as one of the most versatile options for users who want to personalize their Linux experience without sacrificing performance.
What is Wallpapoz?
Wallpapoz is an open-source wallpaper manager for GNOME and XFCE that allows dynamic wallpaper changes based on workspace switching or timed intervals.
How do I install Wallpapoz on Linux?
You can install it by downloading the source code from GitHub, ensuring dependencies like Python, PyGtk, and PIL are installed, and running the setup script.
Can Wallpapoz assign different wallpapers to each workspace?
Yes, that’s one of its core features. Each GNOME or XFCE workspace can have its own wallpaper group.
Does Wallpapoz support time-based wallpaper rotation?
Absolutely. You can configure the program to change wallpapers automatically at intervals you define.
What is daemon_wallpapoz?
It’s the background service that powers Wallpapoz, ensuring wallpapers switch automatically as you move between workspaces or after the set time interval.
How do I fix wallpaper resets after logout?
This usually happens when GNOME session wallpaper services conflict with Wallpapoz. Disabling those or adjusting startup order typically solves the issue.
Conclusion
Wallpapoz is more than a simple wallpaper changer—it’s a powerful GNOME and XFCE wallpaper manager that brings dynamic customization to the Linux desktop. With features like workspace-specific backgrounds, time-based rotation, and an efficient wallpaper daemon, it allows users to create a personalized and engaging environment.

Steam Error Code E87: Causes, Fixes, and Prevention

Millions of players worldwide rely on Steam as their go-to platform for gaming, but occasionally, login issues disrupt the experience. One such frustrating issue is Steam Error Code E87, a problem that prevents users from signing in and enjoying their favorite titles. While the error may seem alarming at first, it is usually linked to account authentication failures, server issues, or client-side problems that can be fixed with a few simple steps.
Understanding the Nature of the Error
This login problem often arises when Steam’s authentication servers cannot validate your credentials properly. Instead of letting you in, the client shows an error message and blocks access. Unlike game-specific crashes, this is a platform-level obstacle that requires troubleshooting related to your account, network, or client software.
In many cases, the issue is temporary and tied to Steam servers being overloaded. However, for persistent errors, the causes often include misconfigured Windows Firewall settings, incorrect date and time synchronization, cached data conflicts, or attempting to log in with an email instead of a username.
Common Reasons Why the Error Occurs
1. Server-Side Disruptions
When Steam servers are under maintenance or experiencing outages, users often face login failures. This means the problem isn’t with your PC or internet, but with the platform itself. Checking the official server status page is the best way to confirm whether the issue is widespread.
2. Login Credential Confusion
Many users mistakenly enter their email addresses instead of their usernames. While Steam allows email use in some contexts, error E87 is commonly linked with authentication mismatches. Entering your registered username is a safer option.
3. Date and Time Mismatch
An often-overlooked factor is the system clock. If your Windows date, time, or timezone are out of sync, Steam’s authentication request may fail because of invalid certificates. This small misconfiguration has caused countless login rejections across different regions.
4. Internet or Firewall Restrictions
A weak network connection, blocked ports, or restrictive VPN settings can prevent the Steam client from contacting its servers. Similarly, overly strict firewall rules may classify Steam as unsafe and disrupt the login process.
5. Cache and Temporary File Corruption
Over time, Steam accumulates temporary data such as download cache and configuration files. When these become corrupted, login requests may return errors. Clearing the cache often resolves these issues immediately.
6. Multiple Device Logins
If your account is logged in across several devices simultaneously, Steam Guard may deny new login attempts. In such cases, deauthorizing all devices and starting fresh helps restore access.
Quick Fixes to Try Immediately
Restart the Steam Client
Closing Steam completely and relaunching it is sometimes all that’s needed. This refreshes your connection to the servers and eliminates minor glitches.
Use Username Instead of Email
Always enter your username rather than your email when signing in. This simple adjustment often bypasses the error entirely.
Sync Date and Time
Enable automatic time synchronization in Windows settings. A properly aligned system clock prevents certificate mismatches that block logins.
Check Server Status
Visit Steam’s official status page or community forums. If the issue is global, waiting until maintenance concludes is the only solution.
Advanced Troubleshooting for Persistent Issues
Disable Firewall or VPN Temporarily
If your firewall or VPN is interfering, disable it for a short time and attempt to log in again. Be sure to re-enable security tools afterward.
Run Steam as Administrator
Launching the client with administrative privileges ensures that Windows does not restrict access to required system resources.
Clear Download Cache
In the Steam client, go to Settings > Downloads > Clear Download Cache. This forces Steam to rebuild temporary data and often eliminates corrupted entries.
Repair Steam Installation
Running Steam with the /repair
command line argument fixes damaged core files. This method is especially effective when the client itself is faulty.
Deauthorize All Devices
From your Steam Guard settings, revoke access to all connected devices. Afterward, log in again with your primary computer to reset session data.
Use QR Code Login
Steam mobile app allows QR-based login, bypassing traditional credential entry. This method often succeeds when manual login fails due to authentication conflicts.
When to Contact Steam Support
If none of the above solutions work, it may be time to reach out to Steam Support. Provide them with details such as your username (not password), system specifications, and troubleshooting steps already attempted. Additionally, avoid repeated login attempts, as this may temporarily lock your account.
Preventing Future Login Errors
- Always use your username for sign-ins.
- Keep system date and time set to automatic.
- Regularly clear Steam’s download cache.
- Ensure Windows Firewall allows Steam through.
- Keep your Steam client updated.
- Avoid excessive login attempts across multiple devices.
By practicing these preventive measures, you can minimize the risk of encountering similar errors in the future.
FAQs
What does Steam error code E87 mean?
It is a login error that indicates Steam servers could not authenticate your credentials properly. This usually results from server issues, wrong login methods, or client-side problems.
Can using my email instead of my username cause E87?
Yes, many users report the error appearing when they attempt to log in with their email address instead of their actual username.
Does clearing the Steam download cache fix the problem?
In many cases, yes. Corrupted cache files interfere with authentication, and clearing them refreshes the login process.
Can incorrect date and time settings trigger the error?
Absolutely. If your system clock is out of sync with Steam servers, certificate verification may fail, resulting in the error.
Should I disable my VPN or firewall to solve the issue?
Disabling them temporarily can help. Firewalls and VPNs sometimes block Steam’s communication with its servers, causing login failures.
Is contacting Steam Support necessary for this error?
Most users solve it on their own, but if the problem persists after trying all fixes, contacting Steam Support is the best option.
Conclusion
Steam Error Code E87 may feel frustrating, but it’s rarely a sign of a serious problem. The issue usually stems from incorrect login practices, temporary server outages, firewall restrictions, or corrupted cache files. By following a structured troubleshooting process—starting with simple steps like checking server status and syncing your system clock, and moving toward advanced fixes like clearing cache or repairing the client—you can resolve the error effectively. With the right preventive habits, you’ll reduce the likelihood of facing this obstacle again, ensuring a smoother gaming experience on Steam.
