Exciting decade for computer chips


In the 2010s computers advanced at a snail's pace. Sometimes people got excited when chips were 10% faster from one year to the next.

However, this decade has been dramatically different and it has everything to do with the circuit sizes on those chips. My 2009 iMac that died had a 42-nanometer chip. My 2017 iMac has a 14-nanometer chip. My new mini-computer has a 4-nanometer chip and it is very powerful for something not much bigger than a Whopper sandwich.

In late 2019 both Microsoft and Sony released their latest generation of video game consoles using 7-nanometer chips. Since these have APUs with the graphics "card" built into the main processor, I wanted something like this in a computer.  I waited almost 4 years to be able to get something similar in a mini-desktop PC.

These smaller circuits are not cheap to make The equipment to make them can cost billions. This is why Taiwan Semiconductor, which made the investment, is the number one manufacturer of these chips.

But it has resulted in a paradigm shift where people realize that they don't have to spend a fortune on graphics cards to play games. The APUs are not as good as a $1200 gaming PC, but they are good enough.

This also has resulted in hand-held gaming systems that are as powerful as a computer and can also be used as a computer when hooked up to a monitor, keyboard, and mouse.

Even the most recent iPhone can double as a gaming system.

Reportedly, Sony, Nintendo, and Microsoft are all coming out with more powerful gaming systems in the coming year. This has been an exciting decade for computer chips.

New Evidence Suggests Long COVID Could Be a Brain Injury

'As part of the preprint study, participants took a cognition test with their scores age-matched to those who had not suffered a serious bout of COVID-19. Then a blood sample was taken to look for specific biomarkers, showing that elevated levels of certain biomarkers were consistent with a brain injury. Using brain scans, researchers also found that certain regions of the brain associated with attention were reduced in volume.

Patients who participated in the study were "less accurate and slower" in their cognition, and suffered from at least one mental health condition, such as depression, anxiety, or posttraumatic stress disorder, according to researchers.

The brain deficits found in COVID-19 patients were equivalent to 20 years of brain aging and provided proof of what doctors have feared: that this virus can damage the brain and result in ongoing mental health issues. 

"We found global deficits across cognition,"'

The Hockey Stick Trial: Science (and free speech) Dies in a DC Courtroom

In a 39-page report, climate scientist Judith Curry gave her opinion that it is "reasonable" to have referred to the hockey stick in 2012 as "fraudulent" in the sense that "aspects of it are deceptive and misleading."

However, Judge Alfred S. Irving excluded Curry's report, which cataloged the manipulations of data to get a hockey stick shape and quoted severe criticisms of the hockey stick made even by climate scientists supportive of the climate-change consensus (most of these made privately).'

...

The trial closed with Mann's counsel, John Williams, making a naked appeal to the jurors' political prejudices. Williams urged the jury to award punitive damages so that no one will dare engage in "climate denialism" – just as Donald Trump's "election denialism" needed to be suppressed. "In 41 years of trying cases to juries," John Hinderaker wrote on the Powerline blog, "I have never heard such an outrageously improper appeal."

Who The Hell Asked For A PS5 Pro?


I've been saying the same thing.  I also bought a powerful mini-PC that can play games.  All of this change, including the consoles and the handhelds, has happened because of AMD's new powerful energy-efficient chips.  Intel has chips too, but they are not quite as good.

The PS5 and the XBox Series X consoles are 10.28 and 12 teraflop machines respectively.  That is still a great deal of performance and you would have to spend a lot on a PC to match that.

Apple is also starting to push gaming on the most expensive iPhones.

I have no faith in Cloud Gaming, but this may eventually be the future where you can run triple-A games on any device with a screen.

I don't need to wear a heavy screen on my head when I have a house full of more screens than I actually use.  Two desktops and an iPhone are enough, but I also have a TV and a laptop that I rarely use, and two tablets I don't use.  I also have a handheld game system that doesn't get much use.

Population growth can be a legitimate issue.  We see that in overcrowded cities everywhere.   We see conflicts arising right now out of overcrowded countries.

However, these problems aren't beyond fixing.

COVID-19



I was trying to be careful and not catch COVID-19.  I was still practicing social distancing when possible, but I caught it anyway.  I don't understand how I got it, but it was either at a chess club or from going to Walmart.  I use the curbside pickup at Walmart, but sometimes I also go into the store.

I thought I would be immune because I am fully vaccinated, but the dominant JN-1 variant has a slightly different spike protein, sometimes bypassing vaccine immunity.  The latest vaccine was supposed to offer some protection from this variant.

Yesterday, I had trouble getting Paxlovid because my pharmacy was sold out.  I had to go to three different pharmacies to get it.  I took my first dose last night and my second dose this morning.  I have eight more doses to go.

Paxlovid is supposed to stop the virus from replicating, which would be very nice.  Any virus will grow exponentially until your immune system kicks in and starts destroying the virus.  The Paxlovid might help the immune system to win the war.

Yesterday, on my second day of COVID-19, I felt like I had a bad cold and could not get anything productive done.  I went to sleep at 10:30 which is early for me.  I woke at 5:00 AM feeling fully rested but wishing I had gotten more sleep.  I got up for a couple of hours, but when I started to feel tired I went back to bed.  I didn't think that I would be able to go back to sleep, but I got just enough of a nap to make me feel better.

I can tell that there is a battle going on in my body.  Either the immune system will win, or the virus will.  So far, I feel better today than yesterday, so maybe my immune system is working.

Fwd: Methane Causing the End of the Ice Age

John,
I think this video came after the one you sent. It talks extensively about a dramatic peak in methane in the atmosphere, which has much more to do with global warming than CO2. I found it interesting.

 

Al, 

This video is three months old and I already saw it.  

I think that his claims are speculative.  We have been in the Pleistocene ice age for 2.6 million years.  It was caused by the huge decline of CO2 over the last 40 million years.  To say that the ice age would suddenly end because there is a spike in methane is speculative.

Although methane is a more potent greenhouse gas than CO2, it exists in the atmosphere at a much lower quantity, like 200 times less.  We measure it in parts per billion.


There is some concern that natural bodies of water, like large lakes, that contain greenhouse gasses could release those gasses if disturbed.

Water vapor is the most influential greenhouse gas.  Minor changes in CO2 level can change how much water vapor is in the atmosphere creating positive feedback.  

There is disagreement on whether clouds produce positive or negative feedback, but I think that common sense would say that it is negative.  If it is positive as the IPCC claims, then this would imply that there would be a runaway greenhouse effect.  However, past spikes in warming did not see this.  Actual climate is complicated involving many factors.

By definition, the amount of radiation hitting the earth and radiating from it is balanced.  Greenhouse gases cause a change in the equilibrium producing a slightly higher temperature.
