LiFi is a new technology that uses visible light communication (VLC) to transmit data using LED light bulbs. It works by switching the LED bulbs on and off very fast to transmit digital ones and zeros. LiFi provides higher speeds than existing wireless technologies and has advantages like availability, efficiency, security and low cost. However, its signals cannot penetrate walls so it requires line of sight and wired bulbs in different rooms. Overall LiFi shows potential for a greener and safer wireless future.
In this i have described the introduction of LIFI technology and history of LIFI like who invent this technology and also i have described the working of LIFI. How its works and how we can get the data from the light. in the LIFI we just have to use VLC.
and i have also described the Applications areas of LIFI technology where it can b used.
LIfi is more speedy in comparison of WIFI.

A powerpoint presentation on Light-Fidelity technology.
Li-Fi (Light-Fidelity) is transmission of data through illumination, sending data through a LED light bulb that varies intensity faster than human eye can follow.
Light Fidelity is an emerging trend of Internet distributions. With speeds such as 100GBPS, it will be no less than a boon for the regular internet users. Lifi is a substitute of wifi where the internet is distributed to customers via lights, even if they are visibly off to the naked eye.
Li-Fi is a new paradigm for optical wireless technology to provide unprecendented connectivity within a localized data-centric environment. The increasing demand for higher bandwidths, faster and more secure data transmission as well as environmental and undoubtedly human friendly technology heralds the start of a major shift in wireless technology, a shift from RF to optical technologies.
The principle is simple: turn a light on and off so rapidly that the human eye can't see the flicker, but a photodetector can nonetheless pick up the stream of 1s and 0s the blinking bulb is transmitting. Compress the data, and you up the throughput even more. Old-style filament bulbs and fluorescent tubes aren't up to the task, but new, LED-based lighting is.

In simple terms, Li-Fi can be thought of as a light-based Wi-Fi. That is, it uses light instead of radio waves to transmit information. And instead of Wi-Fi modems, Li-Fi would use transceiver-fitted LED lamps that can light a room as well as transmit and receive information. Since simple light bulbs are used, there can technically be any number of access points.
This technology uses a part of the electromagnetic spectrum that is still not greatly utilized- The Visible Spectrum. Light is in fact very much part of our lives for millions and millions of years and does not have any major ill effect. Moreover there is 10,000 times more space available in this spectrum and just counting on the bulbs in use, it also multiplies to 10,000 times more availability as an infrastructure, globally.
Li-Fi is the term some have used to label the fast and cheap wireless-communication system, which is the optical version of Wi-Fi. The term was first used in this context by Harald Haas in his TED Global talk on Visible Light Communication(VLC). The technology was demonstrated at the 2012 Consumer Electronics Show in Las Vegas using a pair of Casio smartphones to exchange data using light of varying intensity given off from their screens, detectable at a distance of up to ten meters. For more recent trends in electronics please visit radeshyamece.blogspot.com
In this technology, light is passed through transmission channel as it is the fastest medium. It overcomes the defect of WI-FI as well. Transmission of data takes place through illumination. Using this, we can connect to several devices under a single LED light.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
3. INTRODUCTION
WHAT IS LI-FI??
LI-FI is transmission of data through illumination ,sending data through a LED
light bulb.
LI-FI comes under VLC(VISIBLE LIGHT COMMUNICATION)
4. INTRODUCTION
HISTORY
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. Harald Haas
continues to wow the world
with the potential to use light
for communication.
5. WORKING
How LI-FI works?
operational procedure is very simple, if the led is on, you transmit a digital
1, if its off you transmit a 0. The LEDs can be switched on and off very
quickly, which gives nice opportunities for transmitting data. Hence all that
us required is some LEDS and a controller that code data into those LEDs.
7. Transmission element
Signals from the data input is modulated to
intensity of light.
Transmission side simply contains an led lamp
which transmits the modulated light signals.
This led lamp contains a series of LED’s which
proto fits according to the input given .
8. Receiving element
Receiving elements are “AVALANCHE PHOTO DIODE” and image sensor.
Avalanche photo diode is responsible for converting the light signal into
electrical signal and further the procedure is carried out by image sensor.
11. COMPARISION
WHY VLC??
o Gama rays cant be used as they could be dangerous.
o X-rays have similar health issues.
o Ultraviolet light is good for place without people, but other wise dangerous
for the human body.
o Infrared, due to eye safety regulation, can only be used with low power.
13. APPLICATIONS
Used in traffic lights which can communicate with cars to avoid accidents.
Used in airlines: Generally in airlines mobile phones can’t be used as they
can effect the radars which are main way of communication.
Used in power plants for faster data exchange.
Underwater communications. (rare)
15. DISADVANTAGE
However, everything comes with a disadvantage. The major disadvantage
here is the fact that these signals cannot penetrate walls. So if you want to
move from one room to another, you will need to have a wired bulb
present in that room as well!
16. CONCLUSION
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 hotspot to
transmit wireless data and we will proceed toward the
cleaner, greener, safer and brighter future.
