Cryptocurrency fever

Lately, people are getting caught up by the lure of big scores from cryptocurrencies.

I kinda have a broad brush understanding of them and that’s what most other people have too. Cryptocurrency has been described  as “everything you don’t understand about money combined with everything you don’t understand about computers.”

Unfortunately, most people don’t think about risks realistically.

For example, most people worry too much about the risk of dying from a wild animal encounter. They don’t really factor in the risk from animals we more commonly come into contact with.

The title of a NYT article framed the problem this way, “Afraid of Snakes? Wasps and Dogs Are Deadlier.”

The article reports most deaths aren’t from encounters with wild animals.

Dogs, cattle and horses are much more dangerous.

The wild animals presenting the greatest danger are bees, wasps and hornets!

Cryptocurrencies have a risk most people don’t understand. But they sound very seductive when you hear about their growth

Don’t be surprised if you lose money after investing in something you don’t really understand and that you don’t think is as risky as it is.

Risking what you have (and need) for the chance of getting what you don’t need is a bad idea.

1.5x

The pace of life gets faster. Sometimes I’ll listen to things online at a faster than normal speed. It works best when I’m already familiar with the speaker.

Most platforms let you speed things up. On YouTube, for example, just click on the gear icon in the lower right and select “speed.” The other side of this coin is being able to slow down videos – really handy when you’re learning a new song for the guitar.

There’s a subculture of “fastcast” listeners who generally listen to all their  podcasts at faster speeds so they can keep up with the long list of podcasts they follow. Here’re a couple of interesting points from an article on these fastcasters

A Princeton neuroscientist has pointed out that even at normal speed, most people don’t catch every single word. “If you make it one-third faster, it’s almost perfect — they don’t lose a lot,” he said.

Because recordings played at higher speeds are at a higher pitch, they’re actually easier to hear. Low-frequency noises, like street noise, vacuum cleaners, or airplanes, get in the way of our understanding of people talking. Playing podcasts at a higher speed, the listener is creating a greater acoustic differentiation between the words and lower-frequency background noises.

The brain is able to easily adapt to different speaking speeds. “Your brain responses become slower when I speak slowly, and brain responses become faster when I speak faster.” But, he cautioned, comprehension starts to break down around 2x.

The mystery skull

I saw an exhibit of Irving Penn’s photos covering several subjects with one part featuring pictures of animal skulls.

For most of skulls, I could  match the animal it belonged to. But the coolest looking skull stumped me. It’s here on the right.

I thought maybe it was from an extinct cave bear. It wasn’t. It was the skull of a spotted hyena.

Even knowing they have an incredibly powerful bite and they’re good scavengers and hunters, how could such a gnarly looking skull be inside of a spotted hyena’s head?

The skull was sleek and compact compared to the other skulls Penn photographed. The teeth fit so neatly together, even the really broad one the side.

Looking at those teeth it’s hard to image surviving a bite from them. I doubt any live animal survives if a hyena gets a good bite in place. And as a scavenger, a hyena can probably make off quickly with a nice meal.

Don’t judge a book by it’s cover. There’s an elegant looking skull inside an animal that looks a bit awkward on the outside.

The accessorizing spectrum

I remember Lilly Tomlin saying, “it’s our ability to accessorize that separates us from the lower life forms.”

The other day I saw the first two pics on a “seen on the street” blog called the “Satorialist.” The (I’m guessing unintentional) juxtaposition of these two looks made each one stand out more.

Both people are accessorized, one is after a traditional look of feminine beauty, while the other is striving more towards self-expression and mixing cultures.

The other three pics are from around the web representing different takes feminine beauty and accessorizing from only using body paint, to a small bikini and fake boobs, to a formal full length evening gown.

I’m not trying to leave out men entirely, it’s just easier to focus more on the spectrum of accessorizing used by women. It’s in general a richer and broader palette.

Other animals differentiate themselves but not by accessorizing and without regard to evolutionary pressures. Humans do it for fun and often times without being concerned about attracting a mating partner, although at the extreme end some people are attractive because they’re different.

Any “look” is a message, even the choice to not have a “look.” A person’s look is a signal to other people. Once the look transgresses the traditional the signal can be and is interpreted unpredictably.

The human animal is endlessly fascinating if you leave yourself open to appreciate the spectrum of human expression we use when accessorizing.

Are aliens just hibernating?

Are we alone in the universe, or are we not alone in the universe? Someone once pointed out that a yes in either case is terrifying. Below, I’ve abridged an article called “A New Theory on Why We Haven’t Found Aliens Yet.” Basically it’s because they might be sleeping.

Right now, there’re some big trends in artificial intelligence, robotics, and medical tech indicating the general direction we’re going.

There’re people who think ultimately we’ll become more integrated, physically, with the digital world around us.Maybe, older civilizations have already done it. It’s really just food for thought at this point.

Probability tells us extraterrestrial intelligence should be out there, so why haven’t we found a single sign of it yet?

It could be that we’re simply alone in the universe or that there is some great filter preventing intelligent life from progressing beyond a certain stage. Maybe alien life is out there, but we are too primitive to communicate with it. Or we’re inside some cosmic zoo, observed but left alone.

Now, three researchers have another potential answer. Aliens do exist but they’re just sleeping.

Maybe the universe is too hot right now for advanced, digital civilizations to make the most efficient use of their resources. Their solution: Sleep and wait for the universe to cool down.

Sophisticated life may have elected to leave biology behind and live digitally to enhance their intellectual capacities or to inhabit harsher environments in the universe with ease.

Once you’re living digitally, it’s important to process information efficiently because each computation cost is tightly coupled with temperature. The colder it gets, the lower the cost is.

Surely any aliens could cool down their systems manually, just as we do with computers. It’s possible for a civilization to cool down parts of itself, but that, too, requires work. So it wouldn’t make sense for a civilization looking to maximize its computational capacity to waste energy on that process.

Humans may find the universe to be a pretty frigid place, but digital minds may find it far too hot. It’s likely that artificial life would be in a protected sleep mode today, ready to wake up in a colder future.

Over the next trillions of years, as the universe continues to expand and the formation of new stars slows, the temperature will drop to practically zero, allowing digital life to get tremendously more done. Tremendous isn’t an understatement, either. By employing such a strategy, they could achieve up to 1030  times more than if done today (that’s a 1 with 30 zeroes after it).

Just because the aliens are sleeping doesn’t mean we can’t find signs of them. A sleeping civilization has to preserve resources for the future. Processes that threaten these resources, then, should be conspicuously absent. This includes galaxies colliding, galactic winds, and stars converting into black holes, which can push resources beyond the reach of the sleeping civilization or change their resources into less-useful forms. We could look for those missing phenomena.

But one of the researchers says, “I personally think the likeliest reason we’re not seeing aliens isn’t that they’re sleeping,” he feels it’s more likely that “they don’t exist, or they’re very far away.”

Another researcher thinks, “Any assumption is extremely speculative.” Yet, he said, the theory has a place because it’s important to cover as much ground as possible. A wide set of hypotheses tested one by one—falsifying them, pruning them—gets closer to the truth. So, there’s a modest likelihood their sleeping aliens idea might be part of the answer.

It’s important to keep exploring solutions, trying to understand what might be out there and how this might explain our past and guide our future.

The hungry hummingbird

What would happen if we scaled up a hummingbird to human size? This is one thought, “A 2013 University of Toronto study concluded that if hummingbirds were the size of an average human, they’d need to drink more than one 12-ounce can of soda for every minute they’re hovering, because they burn sugar so fast.”

Yoga time

I’ve been practicing yoga three times a week for a few months.

Because you only have time to do a certain amount things, yoga has begun to shoulder out my practice of Brazilian Jiu Jitsu.

After about five years of BJJ I’d accumulated some minor but nagging ailments and I thought yoga might help.

It has helped but so has cutting out the BJJ. Some of the nagging ailments are probably age related, it’s definitely a young person’s activity. For me, the intensity of BJJ was ok, the problems came from the volume. Basically wrestling as hard as possible three time a week caught up with me.

How do shrinks think?

I’m curious about why people sometimes behave the way they do. Combine a psychologist and an MD and you’ve got a good start at figuring out people’s behaviors. But what insights into the human condition do shrinks have? And what enables them to help people who’re suffering from different forms of mental anguish? Do they know something most of us non-mental health folks aren’t tuned into?

Dereck Sivers jotted down some observations of psychiatrist G. Livingston as Sivers read Livingston’s book. These observations were gleaned over his life as a therapist. I’ve paraphrased and listed some of his ideas but in no special order.

I don’t have a clear idea of what people need to do to make themselves better. I am, however, able to sit with them while they figure it out. My job is to hold them to the task, point out connections I think I see between past and present, wonder about underlying motives.

The vast majority of your life’s results come from small behaviors, repeated thousands of times over the decades. Sure, habits are notoriously hard to change and some of us are compulsively self-destructive. But knowing is much more powerful than not knowing.

A staggering proportion of human activity is motivated by the desire to feel safe and secure.

Nothing outside your own mind can properly be described as negative or positive at all. What actually causes suffering are the beliefs you hold about those things. If your map doesn’t agree with the terrain, then the map is wrong, but It’s difficult to remove an idea with logic that wasn’t put there by logic.

There’re few solutions to life’s problems, only trade-offs.

The three components of happiness are: something to do, someone to love, and something to look forward to. Get plenty of psychological sunshine. Circulate in new groups. Discover new and stimulating things to do.

Most people know what is good for them and what will make them feel better: exercise, hobbies, time with those they care about. They don’t avoid these things because of ignorance of their value, but because they’re no longer “motivated” to do them. They’re waiting until they feel better. Frequently, it’s a long wait.

Only bad things happen quickly. All the happiness-producing processes in our lives take time, usually a long time: learning new things, changing old behaviors, building satisfying relationships, raising children. This is why patience and determination are among life’s primary virtues.

We are responsible for most of what happens to us.

In judging other people, pay attention to how they behave – not to what they promise. Past behavior is the most reliable predictor of future behavior.

The statute of limitations has expired on most of our childhood traumas. Memory is not an accurate transcription of past experience. Rather it’s a story we tell ourselves about the past, full of distortions, wishful thinking, and unfulfilled dreams.

My favorite therapeutic question is “What’s next?” which bypasses the self-pity implied in clinging to past traumas.

Any relationship is under the control of the person who cares the least.

Life’s two most important questions are “Why?” and “Why not?” The trick is knowing which one to ask.

When confronted with a suicidal person I seldom try to talk them out of it. Instead I ask them to examine what it is that has so far dissuaded them from killing themselves. People in despair are intensely self-absorbed. Suicide is the ultimate expression of this preoccupation with self.

When people fall in love, no justification for their attachment is necessary. When people fall out of love, the demands for an explanation are insistent: What happened? Who’s at fault? Why couldn’t you work it out? “We didn’t love each other anymore” is not, in most cases, a sufficient response.

Nobody likes to be told what to do.

It’s possible to live without criticizing and directing everyone around us. I ask people in conflict to withhold that criticism to see if this changes the atmosphere. It’s amazing how radical this suggestion seems.

Awfulizing is the idea that any relaxation in standards or vigilance is the first step toward failure, degradation, and the collapse of civilization as we know it.

The ability to laugh is the most therapeutic.

Our feelings (anger, shame, delight) appear almost instantly, and, left alone, they don’t last very long. But inventing a narrative around an event or a person keeps the feeling going for a very long time.” If you’re not happy with the feeling, try dropping the narrative. It’s your narrative, the story you have to keep telling yourself again and again, that’s causing the feeling to return.

Parents have a limited ability to shape their children’s behavior, except for the worse. Our primary task as parents is to convey to our kids a sense of the world as an imperfect place in which it is possible, nevertheless, to be happy. Do this by example. Demonstrate qualities of commitment, determination, and optimism.

Parents can try to teach the values and behaviors that they’ve found to be important, but it’s the way we live as adults that conveys the real message to our kids about what we believe in. Whether they choose to integrate these values into their own lives is up to them. Kids have a keen nose for hypocrisy.

Behavior that’s reinforced will continue; behavior that’s not will extinguish.

Children raised in homes where parental control is severe turn out to have a poor set of internalized limits because they have experienced only rigid external rules. Conversely, in families where there are few constraints children do not have a way to learn those guidelines necessary to live comfortably with others.

“What can I do to make sure this kid turns out well?” Not much, but maybe cutting down on the fights and not trying to control your child’s every decision might help.

Enjoy life even as we are surrounded by evidence of its brevity and potential for disaster. Mental health is a function of choice. The more choices we are able to exercise, the happier we are likely to be.

Forgiveness is not something we do for others; it is a gift to ourselves.

If every misfortune can be blamed on someone else, we’re relieved of the difficult task of examining our own contributory behavior or just accepting the reality that life is full of adversity. Most of all, by placing responsibility outside ourselves we miss out on the healing knowledge that what happens to us is not nearly as important as the attitude we adopt in response.

The intruding guitar

Here’s the thing, you can do anything, but you can’t do everything.

I’m practicing the guitar and slowly getting better but I’m slowly blogging less frequently.

When I started learning the guitar last year I began practicing a little bit every day, so something had to make room for that practice time. That thing has been my blogging. My blog is a place where I can make notes to myself which means that not blogging as much doesn’t really impact anyone else.
