Google proposes 13 emoji to depicts professional /working women

In an effort to better represent women in today’s digital conversations, Google has come up with 13 new emoji depicting them in various lines of work, such as healthcare, technology and agriculture. They’re included in a proposal (PDF) to the Unicode Consortium, which is responsible for standardizing emoji worldwide.

A group of Google developers has designed a set of 13 new emojis they believe will better represent and depicts the modern woman in day to day life.  The new emojis show woman in roles such as doctors, tech workers, mechanics, farmers, educators and rock stars.

There are some Unicode shortcode to show or generate emojis which are shows the Woman and Man emojis…

The Google team  also pointed out that young women are the heaviest users of emoji and are more likely to use emoji at work while communicating with peers.It’s also worth noting that the proposal includes representation of male emojis in these professions.

The Increasing Reach of Virtual Reality (VR)

Whats is Virtual Reality?

Virtual Reality (VR) is a technology that makes users feel in a Virtual Environment with the help of computing systems and specifically designed software.

The term “Virtual Reality “ itself is comprised of two words i.e. Virtual and Reality .Virtual means “not real” but “like real” and reality. Thus Virtual Reality means anything that is near to reality. Technically Virtual Reality is described as “a computer generated three dimensional environment” in which a person can interact or manipulate objects of such environment.
As Wikipedia states

Virtual reality or virtual realities (VR), also known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user’s physical presence and environment in a way that allows the user to interact with it. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell.

How Virtual Reality is achieved?

In Virtual Reality (VR) with the help of computer technology a simulated environmen
t is created in which the computer is transformed into a gatekeeper to an artificial world. Unlike usual graphic experienc
e instead of viewing a screen in front of users and keyboard or mouse for input, VR places the user inside that sim
ulated environment. Users can also interact within that given environment and manipulate objects in the virtual world with their sense such as hearing, touching and watching. There are a range of systems that are used for this purpose, such as headsets, Omni-directional treadmills and special gloves. These are used to actually stimulate our senses together in order to create the illusion of reality.

Following are the main components of a virtual environment:

1. The visual displays that immerse the user in the virtual world.
2. The graphics rendering system that generates the ever changing images at 20 to 30 frames per second.
3. A tracking system that continuously informs the position and orientation of the user’s movements.
4. The database construction and maintenance system to build and maintain a detailed and realistic model of the virtual world.
5. A sound system that can produce high quality directional sounds and simulated sound fields.
6. Devices like tracked gloves with pushbuttons to enable users to specify their interactions with the virtual objects.

Span of Virtual Reality:

Virtual Reality can lead to a new exciting world of innovations and entertainment. Entertainment industry is Billion Dollar market where new technologies play major role to create a huge user base. Virtual Reality is getting popular nowadays for such an immersed experience in Gaming, Entertainment and training areas. Whether it’s an expensive, dangerous or impractical to do something in reality, VR makes it real for you.

VR is increasingly playing major significance in following areas:

• Architecture
• Construction
• Sports
• Medical
• Gaming
• Entertainment
• Cinema

Military training to Medical surgery training can be experienced more deeply than real. It will not be surprising if we say

Virtual Reality or Immersed System can change digital interface systems we see today.

Internet of things (IoT) ` BOON OR CURSE

Kevin Ashton, cofounder and executive director of the Auto-ID Center at MIT, first mentioned the Internet of Things in a presentation he made to Procter & Gamble in 1999.

Internet of things(IoT) @Techmantr

As Wikipedia stated “The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data.”

More technically The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

Internet of things – concept @Techmantr

A thing, in this context, can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low — or any other natural or man-made object that can be assigned an IP address and provided with the ability to transfer data over a network.

IoT – smart water bottle

Practical applications of IoT technology can be found in many industries today, including precision agriculture, building management, healthcare, energy and transportation. Wearables and activity monitors are common examples that can monitor your heartbeat sometimes your steps and send analytical reports to your smartphones. More technologies are emerging that promises to make daily life easier last thing I have heard about latest Iot is smart hydration reminder ` an intelligent water bottle that reminds you to drink water.
Operational technology (OT) and information technology (IT), allowing unstructured machine-generated data to be analyzed for insights that will drive improvements.

This technology had led IPv6’s huge increase and also a massive world of data in term massive we are talking about petabytes (1petabyte = 1024 gigabyte) of data.

Internet of thing is getting popular day by day and major companies are investing to raise this technology further. Recently BMW launched it concept video at Microsoft’s Build 2016 Conference, Microsoft too unveils cloud and IoT innovations for developers.

As a new technology or innovation arise it also create new problems and difficulties Iot is also facing problem of cyber-attacks and virus threats. An increase in the number of smart nodes, as well as the amount of upstream data the nodes generate, is expected to raise new concerns about data privacy, data sovereignty and security

No doubt this innovation has great potential of simplifying life and a huge market of smart and intelligence demanding community. But it also has its other face that is making us Digitally handicapped.

Node.js and its universe

Understanding Node.js: Powering the Modern Web

There’s no doubt that JavaScript has taken over the web development world. Its popularity has transformed how developers build websites and applications. With JavaScript now running not only in browsers but also on servers, the possibilities for web development are broader than ever before.

What Is Node.js?

According to the official Node.js website:

“Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.”

In simple terms, Node.js allows JavaScript to run on the server side, enabling developers to build scalable and high-performance web applications using just one programming language—JavaScript.

A Brief History

Node.js was introduced in 2009 by Ryan Dahl at a JavaScript conference. His goal was to empower the server side with the capabilities of JavaScript.

Before Node.js, developers typically used two separate languages for web applications:

• PHP or Python for server-side logic

• JavaScript for client-side scripting

This dual-language setup often created complexity in bridging both ends and debugging issues. Node.js solved this problem by allowing developers to use JavaScript across the entire stack, from front-end to back-end, simplifying development and improving efficiency.

Why Node.js Is So Fast

Node.js achieves its incredible performance through two core features:

1. The Event Loop: A system that handles multiple requests asynchronously without creating new threads for each connection.

2. The V8 Engine: A powerful JavaScript engine developed by Google for Chrome, known for its speed and optimized performance.

This combination makes Node.js perfect for real-time, data-intensive applications that run across distributed devices.

Installing Node.js

For Windows Users

1. Visit https://nodejs.org.

2. Download the MSI installer for your system version. The filename usually looks like:
   node-vX.X.X.msi

3. Run the installer and follow the on-screen setup instructions.

Once installed, open the Command Prompt (cmd.exe) and verify the installation by typing:

You should see the version number of Node.js that was installed.

Testing Node.js

After installation, Node.js introduces a new command:

You can use this command in two ways:

1. Interactive Mode (REPL)

Type node in the command prompt and press Enter.
You’ll see a > symbol where you can directly write and execute JavaScript code.

Example:

You can also explore the environment by running:

This is a great way for beginners to experiment with JavaScript commands.

2. Running JavaScript Files

You can also write JavaScript code in a file and execute it using Node.js.

Example:

1. Open your preferred text editor and create a file named first.js.

2. Write the following code:

3. Save the file and run it in the terminal using:

This simple script creates a basic web server that listens on port 3000 and serves a small HTML message.
You can open http://localhost:3000 in your browser to see it in action.

How Node.js Handles Requests

Node.js is built on an asynchronous, non-blocking architecture. This means it doesn’t wait for one operation to complete before moving to the next. Instead, it uses callbacks to handle responses when tasks are done.

For example, when Node.js sends a request to a database, it doesn’t pause to wait for the response. It continues executing other code while waiting for the callback to return the result.

This design makes Node.js ideal for handling thousands of simultaneous connections with minimal system resources, making it a favorite choice for modern web applications and APIs.

Why Developers Love Node.js

Here are some key reasons behind Node.js’s widespread adoption:

• Single Language Development: JavaScript across both client and server sides.

• High Performance: Thanks to the V8 engine and event-driven architecture.

• Scalability: Handles multiple simultaneous connections efficiently.

• Large Community Support: Thousands of open-source libraries and packages available.

• Cross-Platform Compatibility: Works on Windows, macOS, and Linux.

What’s Next?

Once Node.js is installed and running, the next step is to explore npm (Node Package Manager) — a tool that helps you install and manage thousands of packages and libraries easily.

In upcoming discussions, we’ll dive deeper into npm, and explore other advanced features that make Node.js one of the most powerful platforms in modern web development.

IP Spoofing

I

What is IP Spoofing?

IP Spoofing is a cyberattack technique in which the attacker disguises their computer’s IP address to make it appear as if the data packets are coming from a trusted source. In simple terms, it means faking an IP address to deceive systems and gain unauthorized access.

This method allows hackers to hide their real identity and trick systems into believing that the data they’re receiving is from a legitimate or familiar device.

How IP Spoofing Works

An IP address uniquely identifies a device on a network. During IP spoofing, attackers modify the sender’s address field in the IP packet header to make it look like it’s coming from another machine.
When the victim system receives this packet, it believes it’s from a trusted source and may grant access or exchange data — which the hacker can exploit.

Basic Concepts

• IP (Internet Protocol): A set of rules that govern how data is sent and received over the internet.

• Spoofing: The act of impersonating another entity by falsifying information.

IP spoofing exploits trust relationships between connected systems. For example, if one server trusts another’s IP address, an attacker can spoof that trusted IP to gain access.

Types of IP Communication

• IP: Connectionless and unreliable (packets are sent independently).

• TCP: Connection-oriented (establishes a reliable connection before data exchange).

Blind Attack

In a blind spoofing attack, the attacker cannot see the responses from the target system. Despite this limitation, the attacker can still guess sequence numbers and establish a fake connection.

Steps in an IP Spoofing Attack

1. Select a target: The attacker identifies a victim system.

2. Find a trusted host: They locate a device that the victim system already trusts.

3. Disable the trusted host: The attacker makes the trusted system unavailable.

4. Forge sequence numbers: They create fake TCP sequence numbers to impersonate the trusted host.

5. Initiate a connection: A connection is made using the spoofed IP address.

6. Execute commands: Once connected, attackers can plant backdoors or run unauthorized operations.

Common IP Spoofing Attacks

1. Man-in-the-Middle Attack

The attacker intercepts communication between two systems, secretly relaying or altering data while appearing invisible to both parties.

2. Routing Attack

The attacker redirects routing information so that data travels through their own system instead of the intended route.

3. Flooding / Smurfing Attack

In a flooding attack, the attacker overwhelms the victim with fake connection requests.
In a smurfing attack, spoofed ICMP packets are sent to a broadcast address, causing all devices on the network to respond simultaneously — overwhelming the victim’s system.

Important Facts about IP Spoofing

• The IP protocol is inherently weak and does not verify the sender’s identity.

• Routers and nodes on the network path generally do not validate source IP addresses.

• It’s impossible to completely eliminate IP spoofing, but proper security measures can reduce the risk.

Disabling the Ping Command

The ping command, while useful for testing network connections, can also be exploited in Denial-of-Service (DoS) attacks.
Attackers can flood a system with ICMP packets using ping, which consumes bandwidth and system resources, eventually making the victim’s system unresponsive.

Using Firewalls for Protection

Firewalls are an essential defense against spoofing attacks. They help by:

• Limiting traffic only to authorized services.

• Controlling access from both inside and outside the network.

• Filtering packets to block suspicious or spoofed data.

Common firewall tools include iptables, ipchains, and various commercial firewall solutions. For enhanced protection, organizations often use multiple layers of firewalls to monitor and secure network traffic effectively.

Conclusion

IP spoofing is a serious cybersecurity threat that exploits the fundamental weaknesses of internet communication. While it cannot be fully eradicated, awareness and preventive measures — such as using firewalls, disabling unnecessary network commands, and enforcing authentication — can significantly reduce the chances of a successful attack.
