Li-Fi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. It can provide higher speeds than Wi-Fi and has a wider bandwidth. Li-Fi works by varying the intensity of light from an LED to transmit data, with off-the-shelf LED bulbs able to transmit data at speeds up to 100 times faster than Wi-Fi. It offers several advantages over Wi-Fi as the light spectrum is much larger and radio frequencies are becoming crowded. However, Li-Fi also faces challenges as it requires line of sight and has a limited range.

Lifi technology
Li-Fi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. It was invented by Professor Harald Haas from the University of Edinburgh. Li-Fi transmits data through LED bulbs and receives it with photoreceptors, providing higher speeds than Wi-Fi without interference. Potential applications include use in traffic lights, industrial settings, airplanes, and underwater where radio frequencies do not work well. While Li-Fi provides more security and bandwidth than Wi-Fi, it requires line of sight and lights to remain on for operation.

Introductio to Li-Fi
Li-Fi is a new technology that uses visible light communication and light-emitting diodes (LEDs) to transmit data wirelessly. It is the optical counterpart to Wi-Fi, transmitting data using light rather than radio waves. Li-Fi can provide much higher speeds than Wi-Fi and has advantages such as no interference with other electronic devices, better security since light cannot pass through walls, and an unlimited number of users without affecting speed. However, it requires line of sight between the transmitter and receiver and is limited by obstructions blocking the light. The document discusses how Li-Fi works, compares it to Wi-Fi, reviews its advantages and disadvantages, and potential applications in areas like hospitals.

Sharing and setting in salesforce
The document discusses sharing and settings in Salesforce, including organization-wide defaults (OWD), sharing rules, and territory management. OWD determine the baseline access and permissions users have to records they do not own. There are different OWD levels of access. Sharing rules extend sharing access to users in groups, roles, or territories, providing exceptions to the OWD. There are owner-based and criteria-based sharing rules. Territory management allows grouping customer accounts based on defined criteria using territory types, models, and hierarchies.

Project shield
Project Shield is a free service from Google that protects websites from DDoS attacks. It acts as a reverse proxy, receiving traffic on the website's behalf and filtering out harmful requests before sending safe traffic to the website's server. This protects sites from being overwhelmed by blocking attacks and absorbing traffic through caching content. The service aims to help websites with media, election, and human rights content that may be targets of censorship through DDoS attacks.

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.Biomedical Knowledge Graphs for Data Scientists and Bioinformaticians

- 3. Wireless Fidelity Wi Fi is a wireless networking technology that allows Computer and other devices to Communicate over a Wireless Signal.
- 4. 1.4 Million 5 Billion
- 5. Radio Spectrum is congested but the demand for wireless data double each year. Every thing, it seems want to use wireless data but the capacity is drying up.
- 9. LI-FI is transmission of data through illumination, sending data through a LED light bulb that varies intensity faster than human eye can follow.
- 10. The technology truly began during the 1990's in countries like Germany, Korea, and Japan where they discovered LED's could be retrofitted to send information. Harold Haas continues to wow the world with the potential to use light for communication .
- 14. Radio Waves Infrared Rays Visible Rays Ultraviolet Rays X- Rays Gama Rays Gama rays cant be used as they could be dangerous. X-rays have similar health issues. Ultraviolet light is good for place without people, but other wise dangerous for the human body. Infrared, due to eye safety regulation, can only be used with low power. HENCE WE LEFT WITH THE ONLY THE VISIBLE - LIGHT SPECTRUM.
- 16. Traffic Light Traffic lights can communicate to the car and with each other. Cars have LED-based headlights, LED-based cack lights, and cars can communicate with each other and prevent accidents in by exchanging information.
- 17. Airplanes Whenever we travel through airways we face the problem in communication media ,because the whole airways communication are performed on the basis of radio waves. To overcome this drawback on radio waves , li-fi is introduced.
- 18. In Ocean Beds Li-Fi can even wok underwater were Wi-Fi fails completely, thereby throwing open endless opportunities for military/navigation operations.
- 19. Intrinsically Safe Environment : Visible Light is more safe than RF, hence it can be used in places where RF can't be used such as petrochemical plants .
- 20. Light does not pass through walls. Li Fi requires line of sight. A major challenge facing Li-Fi is how the receiving device will transmit back to transmitter. High Installation cost of VLC system.
- 21. The possibilities are numerous and can be explored further. If this technology can be put into practical use , every bulb can be used something like a Wi-Fi hotspots to transmit wireless data.
- 22. If all the effort is put together to make this technology in practical use it will be proved as a milestone in technology And the world will find a new era of .
