"Guruji" is a search engine that was specifically designed for Indian users, aiming to provide more relevant results by utilizing algorithms tailored to the Indian context, making it one of the first crawler-based search engines developed entirely in India; it was launched in 2006 by Anurag Dod and Gaurav Mishra, both graduates of the Indian Institute of Technology Delhi.
Key points about Guruji:
Focus on Indian content: Unlike general search engines, Guruji prioritized websites and information most relevant to Indian users and queries.
Proprietary algorithms: The search engine used unique algorithms to understand and rank Indian language content effectively.
Music search popularity: Guruji gained recognition for its music search feature, allowing users to easily find and play music from various sources.
Challenges and decline: Despite initial success, Guruji faced challenges related to copyright infringement, particularly regarding music search, and eventually lost ground to larger search engines like Google.

It's important to note that this is not an exhaustive list, and many other countries are also contributing to the development of AI tools. The field of AI is constantly evolving, and new players are emerging all the time.
While still in development, 6th-generation aircraft are envisioned to be a significant leap beyond the capabilities of current 5th-generation fighters. Here's a breakdown of the key differences:
1. Enhanced Stealth:
6th generation aircraft aim for unmatched stealth, potentially achieving near-invisibility to radar across multiple frequency bands and angles.This could involve advanced materials, design, and electronic warfare techniques.
2. Increased Autonomy:
These aircraft are expected to have optionally manned capabilities, meaning they can fly with or without a pilot.Artificial intelligence (AI) will play a crucial role in decision-making and potentially even controlling the aircraft in certain situations.
3. Advanced Connectivity:
6th generation fighters will be integrated into a highly networked battlespace, seamlessly sharing data with other aircraft, drones, and ground systems. This will enable better situational awareness and coordinated operations.
4. Next-Generation Weapons:
These aircraft may utilize directed-energy weapons, such as lasers or high-powered microwaves, for both offensive and defensive purposes.They will also carry advanced missiles with increased range and precision.
5. Improved Performance:
6th generation fighters are likely to feature variable-cycle engines that can optimize for both fuel efficiency and high-speed performance. They may also have improved maneuverability and range compared to 5th generation aircraft.
6. Human-Machine Teaming:
The cockpit will likely be replaced with a virtual cockpit presented on a helmet-mounted display, giving the pilot 360-degree vision and AI-enhanced battlefield awareness. This will allow for a more intuitive and efficient interaction with the aircraft's systems.
7. Digital Design and Engineering:
6th generation aircraft will be designed using advanced digital engineering techniques, allowing for faster development cycles and more efficient optimization of the aircraft's design.
In essence, 6th generation aircraft will be:
More stealthy
More autonomous
More Connected
More lethal
More adaptable
These advancements will make 6th generation fighters a dominant force in future air combat scenarios.
It's important to note that the development of 6th-generation aircraft is still ongoing, and many of the specific technologies and features are still being researched and tested. However, the overall vision is clear: to create a fighter jet that is far superior to anything that has come before.
5th generation aircraft use a variety of radar-absorbent materials (RAM), not just one metal. These materials are designed to absorb radar waves and reduce the aircraft's radar cross-section, making it harder to detect.1
Here are some common components of RAM used in 5th-generation aircraft:
Ferromagnetic materials: These materials, such as iron or nickel alloys, can absorb radar waves through a process called magnetic hysteresis.
Conductive polymers: These materials can absorb radar waves by allowing electrons to move freely within them.2
Carbon-based materials: These materials, such as carbon nanotubes or graphene, can absorb radar waves due to their unique electrical and mechanical properties.3
The specific composition of RAM varies depending on the aircraft's design and the types of radar it is designed to evade.
It's important to note that RAM is just one component of stealth technology. 5th generation aircraft also incorporate other features, such as:
Shape:The aircraft's shape is designed to deflect radar waves away from the source.4
Materials: The aircraft's materials are chosen to minimize radar reflection.5
Electronic countermeasures: The aircraft can use electronic countermeasures to jam or spoof enemy radar.
Together, these features make 5th generation aircraft very difficult to detect by radar.
