Compassion

Last Friday we did a family movie night and watched “Wonderwoman” in the local theatre. I tend to get emotional during movies, especially when the film music supports the plot. When my eyes got a little watery during a WW I fighting scene Ro leaned over, took my hand and said: “It’s alright, daddy. – Do you want to leave for a while?”

We took a quick bathroom break, where he re-assured me “It’s OK, it’s just a movie, daddy!” – he used *my* line 🙂

Then he went on to inquire what made me so sad: “Is it because the Germans are losing?”

I told him it wasn’t – (and it was *not*). I just had to hug him. He’s so sweet. (The real reason was because there are no superheroes in real wars and all those people actually died). The magnitude of suffering that really occurred during the two world wars makes my head explode. It still does.

Unrelated, Ro and I ate fish last night. He found a fish bone and I told him to be extra careful not to swallow it. He asked if you can die from it and I shared a  real story of a friend’s wife who died from choking on a fish bone. True, sad story.

Ro had made it through half of his dinner. We were eating silently, when Ro suddenly broke out crying: “Daddy!, –  I don’t want you to die!”

Interesting, how he was worried more about my well-being instead of his own.

In the end he finished his entire meal – very carefully.

 

Fasting Mimicking Diet (FMD) – Intermittent Fasting (IF)

Some recently published research out of University of Southern California shows some promising results for a diet that mimicks fasting for one week once a month. The diet asks for 1200 calories for the first fasting day and only 750 calories for the following 4 days.

Day one of the diet comprises:

  • 10 per cent protein, 56 per cent fat and 34 per cent carbohydrate, making 1,090 calories

Days two to five:

  • Nine per cent protein, 44 per cent fat and 47 per cent carbohydrate making 725 calories

The diet is observed to jump-start the immune system and thereby generating a plaethora of positive health effects ranging from lower cholesterol and better cancer prevention/recovery.

I’m always interested in strategies that emulate the eating behaviors our ancesters were exposed to and our bodies adapted to over thousands of years. This appears to be a promising one – more research needed…

Layered Technology

Sometimes the sum of two technologies is greater than 2 and when you experience it the first time it’s magic. Yesterday was such a day for me. We’ve enjoyed wireless internet on smartphones for years. Voice over IP telephony to anywhere around the world is the status quo. We’ve also had Bluetooth technology for over a decade now. Active noise cancelation in aviation headsets has gone mainstream around the same time.
But yesterday I’ve used all these technologies the first time together in one application: Calling Germany from my airplane over West Texas while en rourte to Santa Fe, NM as pilot in command cruising with seamless ease and the engine humming at 95dBA. I was wearing my Bose A20 active noise cancellation headset with Bluetooth connected to my Samsung Galaxy S7 cell phone (which processor was designed by our team in Austin, TX I might add). I was talking to ATC a minute ago over the radio, when I made a phone call to my mom in Germany, while airborne. The voice was loud and clear – pure magic! Magnificent!

Layered Technology at work.

Is life predetermined? For all practical purposes the answer is NO

If you’re in a rush here’s the quick answer: If life was pre-determined we’d be able to forecast the weather perfectly, too.

Recently I’ve spent quite some time on the topic of artificial intelligence and the fascinating question of what is consciousness. What would it entail to build a man-made self-conscious system? Along came the question of predeterminism of a system and predeterminism of life. Small things.

I’m a CPU architect by profession and have spent many waking hours of my life creating deterministic simulation environments to verify our complex micro-processors. This sounds easy but is actually really hard. It also means that you need to limit yourself to certain design styles that yield deterministic and therefore perfectly reproducible results. A good example of things that can destroy determinism are asynchronous events in a real system, such as interrupts (i.e. keyboard key strokes) that can invoke interrupt routines and disrupt the expected instruction stream. This particular instance is a solvable problem, but in general asynchronous events in non-linear systems are the culprit.

In complex systems with non-linear chaotic behavior, such as weather systems, we can make statistical assertions about their general behavior. But when it comes to determining exactly how the system is going to behave close to a points of instability not even infinite precision in the description of the current condition can predict the exact outcome. We can only make statistical statements about the outcome. This property of chaotic systems prevents us from predicting all asynchronous events that might affect our lives in one way or another. These complex and at times unpredictable behaviors apply as much to weather systems as they apply to outbreaks of diseases that might affect certain individuals. Think of a viral infection causing fever and seizures in humans, heavily affecting their thinking process. Physical diseases might even permanently alter brain structures and synaptic connections. All of which would have the potential to change an individuals behaviour/mood/decision making process in the future. Please note that I’m talking about conscious decision making of the individual. Taken to the extreme sicknesses can cause personality changes that will alter a persons decision outcome. I.e. as a result of such a personality change someone decides to persue a different professional career, with far reaching consequences for his life in the long term (economic outlook, location of job, consumed literature, etc.)

So while for long periods of times individuals live in the linearly predictable parts of the world and causing behaviors that appear to be largely predictable (i.e. I get on the train every morning to get to work and then attend a recurring meeting), these asynchronous events can wreak havoc on long term outcomes of decisions affecting an individuals life.

Therefore predeterminism isn’t a property of human life or even biological life as a whole. But it’s largely predictable enough to exploit long times of relative stability in ways to learn and predict and benefit from these behaviors – for yourself and 3rd parties.

So where does that leave machines? That’s a topic for another post…

 

Sport Events – Austin X-Games 2016

Last week-end our family went to attend this year’s X-Games in Austin – the last time before the event moves to a different city to capture the next audience. The Event was hosted at the new F1 racing track “Circuit of the Americas” for the last two years. We got to see the BMX bike finals, moto-cross, slack line competition and skate board contests.

This was a large event with tens of thousands of people expected to attend, although this year’s Games were partially rained out and many events were delayed to Sunday, the last day.

It was awesome to watch the action of the sport competition, and the well oiled commercial machine attending to the spectators. While standing there it hit me that there were actually four differnet type of groups involved with the X-Games. All united by the event, but driven by very different motivations:

First there are the athletes. They want to compete with the best in their sport and push the limits of what is possible.

Second there are the event organizers of the commercial venue. They have an interest to attract the largest crowd possible to maximize their profit.

Thirdly there are the broadcasters who own the TV rights of the event who have a need to spin a good story and to sell lots of TV ads for commercial breaks. They need the event to look good on the screen and to have a story that keeps the TV audience glued to the screen across commercial breaks. Sadly while the most invisible participants locally, they have the furthest crowd reach.

And lastly, there are the local spectators like our family, who attend the event. They pay their own admission to feel priviliged to be “right where and when it happens”. They just want a cold drink and are looking for a good time. Many fail to realize they are the required event backdrop for the broadcasters, and the reason to make the event commercially viable for the organizers.

As you can see the athletes are only a small aspect of this commercially well oiled machine. The stronger dependencies actually run through the other groups.

But all these groups interact directly or indirectly in “needs” and “wants” relationships. X-Games are in the commercial epi-center of trend-setting. You can witness companies at the events, trying to utilize the image of the games to establish or re-invigorate their brands. There was Harley-Davidson, trying to get a more modern image and finding new customers beyond the vaning baby-boomers. Or iFly, the Austin business that allows “free fall” in a vertical wind tunnel for anybody who was willing to wear a jump suit.

The event was promoting a feeling and everybody wanted to be part of that in their own way.

We enjoyed the X-Games and I’m sure we’ll catch one or two X-Games contests on TV next year – as part of a different crowd. But being the athlete has to wait for another life time.

 

A new Folding Bike

I’ve got myself a 20″ folding bike that I have converted into an E-Bike.

Last year I had supported a start-up on Kickstarter to create a universal electric bycicle wheel. When I received the first product this year I had the vision to create a new small folding bike that I can take along on out private airplane. The 50cc motor scooter I have for that works fine, but it stinks of gasoline, which is quite annoying on the plane. So here’s the clean solution: The picktures show the non-geared out of the box version of the bike, without the electrical wheel installed yet.
