New scam with caller pretending to be from TRAI

 I've watched enough scam bait videos on YouTube to know that this is a common tactic used by scammers. They try to create a sense of urgency and fear to get you to give them money. It's important to remember that real government agencies or service providers will never ask for personal information or payments over the phone. If you're unsure, verify the information through official channels. Recently, I was the target of a particularly egregious robo-scam. A robotic voice, claiming to be from the Telecom Regulatory Authority of India (TRAI), informed me that my phone numbers were about to be blocked due to a violation. I was supposed to press a number to proceed. When I did I was connected to the scammer, who seemed completely unaware of my name, proceeded to mention another phone number that was allegedly registered against me. The audacity of this person was astounding. They not only accused me of wrongdoing but also demanded a payment to prevent my numbers fr

 1. With ‘Digital Twins,’ The Doctor Will See You Now - This article talks to a computer scientist, Amanda Randles, who is creating digital twins of people’s circulatory systems. It discusses what digital twins are and how they’re created. It also goes into the challenges and future possibilities of this kind of research. Some important points are that digital twins can help doctors diagnose and treat diseases more effectively, and that they are becoming more and more realistic. My Take : This is such an interesting development IMHO that it could end up predicting heart attacks to a degree that preventive care for it can actually be performed much before catastrophic situation arises. By making it a part of annual checkup, I think we can make preventive healthcare more effective. 2. What Is Analog Computing? - This is an article about analog computing. It discusses what analog computing is and gives examples of analog computers. Analog computers represent a physical system with mathe

Samsung's Solid State Battery with 9 minute charging, 600 miles range for EVs and 20 year lifespan - Samsung is shaking up the EV battery game with their new solid-state design. Boasting a massive 600-mile range on a single charge and crazy-fast 9-minute charging, these batteries promise to revolutionize electric vehicles. Samsung also hints at a 20-year lifespan, putting range anxiety to rest. However, expect to see this tech first in pricier EVs, and remember, Chinese battery makers are hot on their heels with similar claims. My Take: The progress in the space of battery technology has been amazing and I now dont believe that Hydrogen and fuel cell technologies need to really leapfrog over things to be viable alternative to these kinds of technologies. I wonder if these techs could reach out cell phones as well to get rid of the daily charging required. I wonder if Samsung would first put these into these into their Galaxy lineup or will they wait for

Courtsey: https://www.isro.gov.in 1. ISRO conducts flight experiment of Air Breathing Propulsion System : ISRO successfully conducted its second flight test for air-breathing propulsion technology. The experiment involved mounting the propulsion system on an RH-560 sounding rocket, India's heaviest in this category. Launched from Sriharikota, the test aimed to demonstrate the technology's functionality at hypersonic speeds. Prior to the mission, extensive ground tests were carried out to ensure proper performance. This successful flight, along with data collected from over 110 parameters, paves the way for further development of air-breathing engines by ISRO.  My Take: ISRO's accomplishments are undeniably impressive. Their ability to achieve significant milestones with relatively modest budgets compared to agencies like NASA is a testament to their efficiency and innovative approach. It's encouraging to see that ISRO has managed to operate largely free from political

Artists impression of Secure IoT, source https://www.mindgrovetech.in/secure-iot 1. Technical Preview of Mindgrove Tech "Secure IoT" SoC : SIoT is probably the world’s first 64 bit microcontroller, clocked at 700 MHz. Shree Kumar has given a very detailed review of this. He gets into the details of how this is an awesome project but also highlights the problems with its current version. My Take: I am really excited that Mindgrove Tech is venturing and building this kind of SoCs in India. Qualcomm, Intel, TI, ST Micro, all have had their development centers in India. I believe we have enough folks who have the expertise to develop top notch SoCs and making a mark in the world. But people would often read the post and think that this project is not perfect. But I dont disagree with them and the first version of any project is not perfect, neither is the second. But only with enough perseverance can impactful products be made. I hope Mindgrove Tech learns from this to improve

1. Self-hosting your location history with OwnTracks : OwnTracks is an open-source alternative to Google Maps Timeline, allowing users to privately track and store their location history. Many are dissatisfied with Google's upcoming changes to location history storage and seek a replacement. OwnTracks involves a server-side component to store location data and mobile apps to report location. The author details a setup using Docker, Caddy, and Tailscale for a private, self-hosted solution. While the initial setup is complex, the author finds OwnTracks promising, with potential for improvement in the mobile app's user experience and the web app's features. My Take: OwnTracks is an interesting alternative. I have not tried it yet, the only thing I am scared of is hosting something which is accessible on the internet.  Source: Florida Museum 2.

Image credit: Google Arts & Culture  1. World's oldest cave art found showing humans and pig : Scientists in Indonesia and Australia discovered the oldest figurative cave art in Indonesia. The painting, located on Sulawesi island, depicts a wild pig and human-like figures and is estimated to be 51,200 years old. This pushes back the date for when modern humans were believed to have creative thought. The discovery suggests that storytelling was a bigger part of early human culture than previously thought. Researchers believe this finding may lead to reevaluation of other cave art sites around the world. My Take:   Humans have probably been telling stories for much longer than 51,200 years, but as words do not fossilise we can only go by indirect proxies like depictions of scenes in art – and the Sulawesi art is now the oldest such evidence by far that is known to archaeology The above is what is the most amazing part of the whole article. There is so much more to learn about th
