Chandrayaan-3 landing: Noida-based tech start-up powers eyes of Pragyaan lunar rover

A Noida-based tech start-up found itself in the front row as India scripted history on Wednesday with the successful landing of Chandrayaan-3. Omnipresent Robot Technologies has worked closely with ISRO on the moon mission series and now has eyes on the moon - quite literally. The company had developed the Perception Navigation Software that the Pragyaan rover will use for the next two weeks.

The Vikram lander within the spacecraft made a powered vertical descent onto the lunar south pole at 6:04 pm as billions watched from around the globe. It also carried the Pragyaan rover which will now explore the crater-filled lunar surface.

“We are very excited and look forward to seeing the Pragyaan rover navigating the lunar surface using our software. This software was originally developed for Chandrayaan-2, but the rover could not be deployed back then. This is now being used for Chandrayaan-3," CEO Aakash Sinha told PTI.

The Shiv Nadar University professor said that the software would capture images of the moon using the two cameras of the lunar rover and stitch them together to generate a 3-D map of the lunar landscape. This software has been in-built in the rover and the image processing will be done onboard the spacecraft. The final 3D model will be transmitted back to the mission control.

Scientists on earth can then take the rover for a tour of the photographed area on the basis of the 3D model of the lunar surface generated by the software.

The Pragyaan rover uses just two cameras which act as its eyes, while the software generates the 3D maps of the lunar surface.

WhatsApp introduces Community Examples Feature for iOS Beta users

Meta-owned messaging platform WhatsApp is set to introduce a feature called "community examples" on its iOS beta version. This feature aims to assist beta users in creating communities on the platform by offering instructional examples.

WhatsApp, a Meta-owned instant messaging platform is reportedly introducing a new feature on its iOS beta version known as "community examples." The new feature has been designed to guide beta users in creating communities on WhatsApp by providing instructional examples. When users access the shortcut, it directs them to an official FAQ containing instructions and tips on community creation, adding groups to communities, and effectively reaching community members through special announcement groups. This feature aims to motivate more users to establish communities within the platform.

Initially, the community examples feature is being rolled out to select beta testers who update their WhatsApp beta for iOS via the TestFlight app. The rollout will gradually extend to more users in the coming days.

In addition to this, WhatsApp recently introduced animated avatars to its iOS beta version. These avatars can be shared with anyone, regardless of whether they are using the beta version. They are intended to enhance the communication experience by infusing stickers with more personality and vitality.

Another recent feature on WhatsApp's iOS beta allows users to send high-quality videos. While some compression is still applied to maintain video dimensions, sending videos in their original quality is not feasible. The default setting remains "Standard quality," and users must manually select the high-quality option whenever they want to send a better-quality video.

Prototype 'Brain-like' chip promises greener AI, says tech giant

A prototype "brain-like" chip could make artificial intelligence (AI) more energy efficient, its developer, technology giant IBM, has said.

Concerns have been raised about emissions associated with warehouses full of computers powering AI systems.

IBM said its prototype could lead to more efficient, less battery draining AI chips for smartphones.

Its efficiency is down to components that work in a similar way to connections in human brains, it said.

Compared to traditional computers, "the human brain is able to achieve remarkable performance while consuming little power", said scientist Thanos Vasilopoulos, based at IBM's research lab in Zurich, Switzerland.

He told the BBC the superior energy efficiency would mean "large and more complex workloads could be executed in low power or battery-constrained environments", for example, cars, mobile phones and cameras.

"Additionally, cloud providers will be able to use these chips to reduce energy costs and their carbon footprint," he added.

'Digital to analogue'

Most chips are digital, meaning they store information as 0s and 1s, but the new chip uses components called memristors [memory resistors] that are analogue and can store a range of numbers.

You can think of the difference between digital and analogue as like the difference between a light switch and a dimmer switch.

The human brain is analogue, and the way memristors work is similar to the way synapses in the brain work.

Prof Ferrante Neri, from the University of Surrey, explains that memristors fall into the realm of what you might call nature-inspired computing that mimics brain function.

A memristor could "remember" its electric history, in a similar way to a synapse in a biological system.

"Interconnected memristors can form a network resembling a biological brain," he said.

He was cautiously optimistic about the future for chips using this technology: "These advancements suggest that we may be on the cusp of witnessing the emergence of brain-like chips in the near future."

However, he warned that developing a memristor-based computer is not a simple task and that there would be a number of challenges ahead for widespread adoption, including the costs of materials and manufacturing difficulties.

Using these components makes the new chip more energy efficient but the new chip also has digital elements.

This makes the chip easier to put into existing AI systems.

Many phones now have AI chips on board to help with things like processing photos. For example, the iPhone has a chip with a "neural engine".

In the future, IBM hopes chips in phones and cars could be more efficient, promising longer battery life and new applications.

Eventually, chips like IBM's prototype could help save lots of energy if they replaced the chips in the banks of computers powering applications powerful AI systems.

They could also cut the water needed to cool the power hungry datacentres. Data centres need huge amounts of electricity to keep them going - a large facility will use as much electricity as a medium-sized town.

Professor of IT at the University of Bath, James Davenport, said IBM's finding were "potentially interesting" but warned that the chip was not an "easy to use" solution to the problem but more like "a possible first step".

3 malware which has been stealing data from the smartphone

Recently it was discovered that there are round three new malware- DarkGate, Emotet, and LokiBot have been detected. All these three malware are reportedly dangerous and they hang the system after entering the high-security system.

In today’s world, everyone is connected to the internet, but ‘with great power comes great responsibilities’- as there are always risks and you need to be very careful. Malware is a harmful virus which can intrude on your personal devices like- laptops, smartphones or computers. This malware can also harm our data and privacy. As per the knowledge- there are around three new malware which have been detected and are considered very dangerous. All these three malware harm the system badly by stealing the data of the users.

ccording to a report by a security research company, recently three new malware DarkGate, Emotet, and LokiBot have been detected. All these three malware are reportedly dangerous and they hang the system after entering the high-security system. These three malware rapidly steal the data of the users. According to research, these malware enter the system through software files and email.

DarkGate Malware

DarkGate Malware malware was discovered in June 2023 in research by the security research company Kaspersky. How deadly this malware is can be gauged from the fact that it easily steals the browser's history by dodging Windows Defender other than the common downloader function. Not only this, but Dark Gate malware also has the ability to change proxy and steal data by going into file management.

Emotet Malware

The Emotet malware is a botnet. Not that this has come up for the first time. Earlier it was known about it in 2021. Now it has resurfaced. Recently it has been shown active again. It is being told that it enters the system through the One Note file. After being activated in the system, it automatically downloads many harmful files through the Internet.

LokiBot Malware

LokiBot Malware was first detected in 2016. Hackers have designed this malware to steal details from many other apps including browser and ftp files. This malware hides in an Excel document. It damages the data once it reaches the system.
