Most people who use foldable phone don't have enough physics knowledge on how camera optics work.

In general good cameras need more thickness. Foldable phone restricts this. So using the same technologies, I can make better camera on non-foldable phone than on foldable phone when the thickness of non-foldable phone is same as folded phone.

So either you get higher thickness when folded or you get inferior photos when compared to non-foldable phone.

That is one of the main reasons, why I don't plan to get a foldable phone.

Finally, Amazon Fire Phone won't be the worst one. It never made any money and was pulled out after releasing only one model.

You got your timelines wrong. When Hayes went bankrupt, hardly anyone had DSL.

In 90s, people used to access internet via dial up modem and the largest modem manufacturer was Hayes. Suddenly, they went bankrupt.

What went wrong?
The highest data rate, a phone modem can support is 56 kbps. They made 56 kbps. Unfortunately, ISPs were not ready. They were still on 28 kbps. Since Hayes 56 kbps model were expensive, they had to heavily discount them and went into a big loss.

What was their response?
They retooled the manufacturing to produce 28 kbps. By the time, they went into full production, the ISPs switched over to 56 kbps. They couldn't sell their obsolete 28 kbps modems.

I see some parallel here.

If the pilot has lost all equipments, then this tech may be useful. But was it required in this incident? Did pilot lose all electronics?

There are just too many ways you can create a beacon which can transmit precise location over encrypted channel in a noisy spectrum that it is impossible to detect and locate the source except by the matching receiver with decryption key.

In future, no one will hire beginner programmers. So everyone will first become experienced programmers and then they will get job! You see, you start coding when you are in kindergarten. By the time, you graduate, you can write "15+ years of coding experience".

FCC deadline requires them to launch 1600 satellites by 31st July 2026 and as of 31st Jan 2026 they have only launched 180 of them. Will they be able to meet this deadline? If not, StarLink will be a global monopoly for quite sometime.

Gas price USD 8/gallon
Electricity 0.15/kwh

Compare that to California:
Gas prices: USD 4.2/ga
Electricity: 0.35/kwh.

If you get 3.5 miles/kwh and 28 miles/ga and drive 12000/yr, your fuel cost saving in California is USD 600/yr. Not enough to justify range anxiety, future battery replacement cost and higher initial investment.

For Norway, it would be close to USD 3000/yr. Definitely worth it.

"A country that has the world's largest population is bound to rank high in terms of the size of the economy"

Few years ago, people were using same language for China.

In 1995, Japan's GDP was 15x that of India. So it is not given. It is a great achievement for India and it deserves congratulations. I am not saying it is worthy of praise, but it still made good achievement. It was 16th in GDP rank in 1994 and now it is 4th.

The title clearly says that India overtakes Japan in total GDP. Nowhere it claims it is per capita or Indians are doing better than Japanese. This should be obvious to any fifth grader.

Despite that there are so many people bashing India and pointing out the obvious.

Let us face it, this is a great milestone for India and we should congratulate India for this achievement. When someone achieves a medal in college for sprinting, you don't put them down by saying how slow that person is compared to Ussain Bolt.

No single metric is enough to compare two vastly different economies such as Japan and India. All the metrics give view from a particular angle. GDP, per capita GDP, PPP GDP and so on.

No one in India is claiming that it has better quality of life either.

This is just one of the measures in which it overtook Japan and that is it. You are vastly extrapolating it for no reason.

The Tata coal plant in the article was build in a very remote location long time ago. Almost all the residents complaining moved there later. It is like you have been grilling burgers all the time and then someone moves in your neighborhood and complaints for smoky smell.

That does not mean that the plant should not be shutdown. But there are always trade offs. However, the residents can move out if they are not happy with the plant.

I had tried in the pass unsuccessfully to search on this. Tried again today and found this on Google AI:

"Professor Padmakar P. Lele was a pioneer in the use of ultrasound for cancer hyperthermia, particularly with his work on scanned, intensity-modulated, focused ultrasound (SIMFU) systems in the 1980s. His research focused on using focused ultrasound to noninvasively heat and destroy tumors, with a goal of heating tumors to \(43^{\circ }C\) with minimal damage to surrounding tissue. His work laid the foundation for modern ultrasound hyperthermia techniques, which are still used today as a treatment for some cancers, often in combination with radiation and chemotherap"

I attended a seminar at my university way back in mid 80s and this was discussed. Ultrasound Hyperthermia as it was called then. I even remember the professor name, it was Lele. Don't remember his university affiliation, so may be hard to do Google search. He presented several successful case studies as well. Maybe, it didn't work as well and was abandoned at that time and with the advancement of AI, software, and better hardware, it can do better job today. The main idea was same. Cancer cells at a faster rate than normal cell when heated. Ultrasound can penetrate and focus on the cancer tumors and do localized heating and kill larger proportion of cancer cells while killing only a few normal cells.
