iPhone 6s+ processor speed

Way back when I had an iPhone 4, I tried running the chess program Stockfish on it in analysis mode, and it was examining around 250,000 nodes per second, which at the time seemed to me to be pretty good for a handheld device.  This was not as good as my desktop, but still a good substitute for it.  Two years later when I got the iPhone 5, the speed had improved to around half a million nodes per second.  Two years after that with iPhone 6+ I was impressed to reach a million nodes per second.  However, I have just upgraded to the  iPhone 6s+, which is a three year old phone, and the same Stockfish program on this phone is examining an amazing two million nodes per second.

Compare this to my late 2009 iMac with a quad core 2.8 ghz core-i7 processor.  For its day it was a top of the line desktop computer, but today it is about average.   Using one core, the Stockfish program examines around 450,000 nodes per second.  If I use all 4 cores then the program sees about 1.5 million nodes per second.  The iPhone 6s+ only has two cores, but it is outperforming my desktop computer by a good margin.  

Since the iPhone 6s+ came out, Apple has released the iPhones 7, 8, 10, and 10s, all of which are faster than the previous generation.  (The 8 and 10 are part of the same generation.)  The 10s is only slightly faster than the 10, because we are reaching a point where the laws of physics won't allow them to make the circuits smaller, therefor faster.  I personally wanted an iPhone 10 or an iPhone 8, because I knew that the processor on those phones kicked ass, but I didn't want to spend a fortune for a phone, so I settled for the good enough iPhone 6s+, which I got on a Black Friday sale for $300.

Speaking of kicking ass, Apple has been doing that with their processor development.  No other mobile phone manufacturer comes close.  Apple is using a 7 nanometer process with their latest phones and tablets.  Compare that to Intel, the world's largest microprocessor manufacturer, who recently backed off of their 10 nanometer chips because of problems and instead released 14 nanometer chips.  AMD, who is already kicking Intel's butt, is scheduled to release 7 nanometer chips early next year, with a whole new line of processors that undercut Intel on price.

This is an exciting time because of how much progress has been made in computer processing power.  It is also impressive how much power Apple has been able to put in mobile devices.  The latest iPad Pro's, which use the same processors as their latest phones, outperform many desktop computers.

AT&T "You Will" Commercials (high quality)

These commercials go back to 1993, and everything they predicted has come true, although the company that brought it to you might be Apple, among others.

Re: Forced back to catch and release

Immigration and Customs Enforcement officials – faced with a lack of housing space, an agreement that limits how long they can detain families and a massive increase in the number of border crossers – are having to resort to releasing illegal immigrants and asylum seekers "out of the front door" in Arizona.

The future

Beginning around 5 billion years from now, the Sun will expand, becoming a swollen star called a red giant. By 7.5 billion years in the future, its surface will be past where the Earth's orbit is now, consuming the Earth.

In 500 million years the tectonic plate movement and geological activity on planet Earth will have stopped, causing it to have a similar fate to Mars. The planet will be dry, lifeless and very cold.

Within half a million years it is extremely likely that the Yellowstone supervolcano will erupt, wiping out life in several nearby states and causing an environmental catastrophe worldwide. However, we are already due for an eruption, and the underground volcano has shown increased activity over the last 30 years. This is a disaster of enormous scale waiting to happen; we just don't know when it will happen. Fortunately people are looking for ways to relieve some of the pressure that is building up beneath the National Park.

Within 100 years we will be almost completely out of fossil fuels, so we will have to rely on other energy sources. The last remaining fossil fuel will be coal, which is estimated to be gone by the year 2150.

Within 50 years machine intelligence will surpass that of all humans combined. This event has been dubbed "the singularity", and it will forever change our fate. From that moment on machines will make most of the technological advances, and possibly at an ever accelerating rate. Over time humans will become more integrated with technology, and we will no longer be purely biological.

Funny.  I don't necessarily agree with his final conclusion about redistributing wealth, but the video is thought provoking

Fwd: Award winning teacher Kerstin Westcott's resignation speech in Green Bay...

This is from my friend Al:

This is one of the saddest teacher testimonies I've seen on YouTube. What's sadder is the general public's complete ignorance of how bad our public school systems have become. Keep in mind, this teacher is speaking about the school system in Green Bay, Wisconsin. If it's that bad there, imagine how bad it is in New York, LA, Chicago, etc.
