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.

Good or bad, it does not seem legal. H1B is controlled by congress and president is required to enforce the laws made by congress. Putting arbitrary 100k a year fee is not in the spirit of the law. Imagine if states like California put 100k fee on gun registration. They can't, because gun ownership is in constitution and states cannot put excessive burden. Same for H1B. It is in a law by congress and president cannot put excessive burden on companies in exercising what is in the law.

You got it totally wrong. This law is abuse of presidential powers. Congress makes H1B law, not president. President is supposed to enforce the law as per the intention of the congress. Imposing 100k per year, is far from any congressman could have envisioned.

This law will mostly be blocked by courts.

Any data? Last time, I checked the data, solar is using less land per unit of electricity produced than all the lands leased by fossil energy companies.

Solar will return the land back intact in future. The fossil energy companies return uninhabitable land.

In practice, solar needs lesser land than fossil energy takes.

First fusion and now space solar. Neither will ever be commercially profitable. Experimental tiny projects aside, neither had or will have any future.

Simple number feeding to either of these system will tell you that the cost is too exorbitant even if we have 100% technology today based on any known science. So unless, we have some fundamental laws of science uncovered which open different avenues, these projects are doomed.

How is the sound quality?

Blasphemy is punishable by death in Pakistan. This applies to you even if you are US citizen and post from US and they think it is a blasphemy. They can arrest you and execute you if you ever visit to Pakistan. This is the law and no government official will deny it or will say they will not implement.

Similar laws may exist in many other countries.

Will US ban Pakistan (and other countries') official's visa? I bet it won't.

I often take screenshot over remote video call (E.g. Zoom) to capture url people are using for presentation (instead of interrupting speakers and asking for the url). Often times people jump around multiple pages and only one or two are interesting to me which I don't have, so I just take a screenshot. I hate when users use safari and all you can see is hostname. As long as it shows enough information that if I copy/paste, it will go to the right url, I am ok.

Fusion power is not there yet. But that is not the biggest issue. The biggest issue is that the most optimistic commercial calculation (assuming the technology will work perfectly) do not show any profitability. Earlier, there was some indirect benefit in terms of clean power, but now solar/wind/nuclear/hydro can provide almost all the electricity needs.

So in summary, fusion as a commercial power will never be a reality. Most scientists that I know working on plasma physics agree on this. However, it is a beautiful science and they need research money, so publicly they cheer such achievements.

Microsoft has a monopoly over Xbox and every developer has to pay commission and can only distribute games after Microsoft signing. How is that any different? Microsoft takes commission off of every sale, why can't Apple take?

Apple provides more service than Microsoft. It allows hosting of the software, manages payment, user feedback, and so on. Microsoft provides no such facility to developers. Plus you have to be a large company to begin with to develop a software for XBOX and you can only develop certain types of games and approved software. You can't even develop a generic app like browser, Adobe, ProCreate etc.

Government is giving far more latitude to Microsoft co tightly control XBOX but not to Apple to tightly control iPhone and other iOS devices. They are no different than XBOX apart from the form factor.

I got a direct response from Zuckerberg and he said that Linux is for high paying developers at FB and AWS and they don't have time to waste on FB. FB is primarily for losers and they don't know anything about Linux, so the ban is justified.

In 2018, I got a laptop with 1060Ti graphics card with 6 GB RAM for under $800. If NVIDIA chips performance has increased 1000x in 10 years across the board, then I would expect 64x improvement in graphics as well. Mr. Huang, please send me a link where I can laptop with 64x speed improvement over 1060Ti and cost under $800.

Based on the benchmarks, desktop version of RTX4090 is 5.6x faster than GTX1060Ti and RTX4090 is way more expensive than GTX1060Ti was in 2018. The recently announced RTX5060 with price of $549 (that Huang claims has speed of 4090) matches 6x performance improvement at similar price to GTX1060Ti. So in 7 years, we get 5.6x improvement. That is way slower than Moore's law.

It is highly annoying typing alt-space to launch CoPilot. Why can't they simplify by just pressing space?

Govt should raise minimum H-1B salary to 130k (or whatever is reasonable) minimum irrespective of profession. Also add 3-6% extra payroll tax. That will make companies look for US workers over foreign workers.
