Sleep deprivation...



Life is sometimes not as simple as two tetrahedra joined together. People join together for many reasons and for other reasons they sometimes split apart.

So why does the splitting apart bit always have to be so difficult, and why does the process have to be so expensive when one of the people doesn't want to cooperate?

Seems to me that it's just a form of slavery when we allow one person to make it difficult for another to walk out of a relationship, especially when the impetus for walking out is that person being intolerably difficult.

I'm still trying to catch up on sleep...

Occam's Razor Isn't Always the Sharpest Knife In the Drawer

Ha.
Don't get me wrong, I'm not down on the scientific approach.
In fact, my livelihood is based on a scientific approach - but engineering vs. science is another topic...

Occam's Razor states that when there are multiple possible explanations, we should lean toward the simplest one. This is usually a reasonably good approach when it comes to correlating empiric data with possible underlying models. Furthermore, it is a useful approach in finding experiments which will prove a given hypothesis with the least effort. It allows us to discard a lot of crap fairly early on, because sometimes good science involves starting with nothing but a hunch and finding results via experimentation. Sometimes the results are totally unrelated to the hypothesis the experiments were developed to prove.

However, when the hypothesis lies outside the realm of easily provable phenomena, an overly zealous adherence to Occam's Razor leads to discarding theories and even direct physical evidence which just doesn't fit in a neat, orderly model of reality.

This bothers me because I feel there is a lot more to this world than what is observable with currently known instruments. Such instruments are, in fact, extensions of physical senses (some pedantist will argue that humans are unlike electric eels and do not posess the ability to sense minute electric charges, or are unlike pigeons in lacking a proven ability to sense the exact alignment of the Earth's magnetic field, but I'll just thumb my nose at the wags and continue). I argue that in fact there are other senses such as feeling and intuition, which are valid albeit not as easily amplified or proven. Feelings as in emotions are well-studied through psychology, sociology, and other behavioral sciences... but here I am talking about feelings as in intuition.

Furthermore, these sensory abilities vary considerably between individuals, unlike better known abilities such as eyesight and hearing which mostly fit a fairly well-known pattern.

This is just one small example. Science is indeed catching up to things that were previously considered outside the realm of science. The convergence is happening, just a bit slowly...

More later.

Cowle's Peak


This is what I'd call a nice short hike. 1.4 miles and 1000 feet up for the best view in the city of San Diego.

That felt good! It's been way too long since I did a decent hill climb!
Next time, Iron Mountain! AND I remember to bring my poetry notebook!

And I had to slack off and take a break part of the way up.














But you have to admit, the view is worth it, and how could I resist stopping every few hundred meters to take some pictures?

Finally, views from the summit:


And finally the trip back down...

Root canal - the sequel

OK, so root canal round 2 was a bit more like what I thought root canal was going to be like. But I think this doctor, Babrak Shoushtari, is really really good. I hope I don't have to see him again but if I needed an endodontist I would definitely go see him again.

The temporary filling came out, some drilling, lots of reaming out the canal, both with a rotary thing, and with various needle-tipped instruments, inspection with a microscope, digital x-rays, and finally relief in the form of hot rubber fillings. did I mention numerous irrigations with solutions including sodium hypochlorite, a.k.a. bleach? Well, thankfully there was a rubber dam installed in my mouth so I didn't have to swallow any of that stuff...

Now try to say "fluffy bunnies" with your mouth all numbed up... go on...

A bird in the hand...

Let's start with the bush part: http://www.youtube.com/watch?v=PgTevNMMuFI
oh gawd I can't believe this guy... The best part was "fool me once uh... uh... uh... (look stupid during pregnant pause)"

And birds. I saw a hawk perched on a street light outside my workplace being harassed by a crow. The crow kept divebombing the poor bird of prey until it finally flew away

We've had dense fog in the mornings lately. I'll have to stop and get pictures...

Victimhood sucks

My goals for my children have gotten more focused, a bit more grounded in reality (so I'd like to believe), and more practical. They are:
  1. Get them through college and at least a bachelor's degree. It's more than life is a struggle when you know things but don't have that degree - when you're young you have the chance to spend a few years focusing on education, and you'd damn well better take it while you have the chance before the raging currents of life sweep you away!
  2. Try to instill some good habits, good hygiene, people skills and other useful things... and
  3. Show them that there are alternatives to victimhood.

What we get from our parents imprints itself deep upon our psyche in a way that is hard to escape, even when we are conscious of it. We may "hate" one or both of our parents for things we decided long ago we couldn't stand. We may deliberately set ourselves up to be the opposite of what we saw our parents as. "Dad was a Democrat, so I'll be Republican." "Mom liked heavy metal, I'll only listen to Mozart." etc.

I would define victimhood as the sense that others are always to blame for your problems. Those who are afflicted with a sense of victimhood rarely think of themselves as irresponsible. Some feel sorry for themselves, sink into depression, and if they get the right kind of help, might pick themselves up and move on. The other type of victimhood I'm familiar with is a self-righteous one which picks up fuel from everyone it comes in contact with. It is very hard to deflate. We'll call this flavor of victimhood PriSI for Pristine Self-righteous Innocent victimhood.

There's not much that can be done for the fully entrenched PriSI victim. The best you can do is not get into playing the rescuer, because whatever you do, it won't be enough. All you'll get is resentment. If a PriSI needs money and you lend them some, it won't be enough. If a PriSI needs a place to stay and you let them stay with you, they'll resent it when you ask them to move on. If you're stupid enough to marry one, they'll go out of their way to make sure you suffer for it when you finally decide to move on and leave them.

The problem with PriSI is that it's infectious and self-covering. Since PriSI sufferers are "empowered" by a sense of the nobility of their own martyrdom, they keep themselves blinded to the defects in the way they deal with others. They have trouble keeping long-term friends because eventually that friend will try to provide feedback on something and will become an ex-friend for daring to suggest that the PriSI person is less than perfect.

But chronic PriSIs are by nature extremely insecure. All that self-righteousness is a desperate attempt to avoid facing the abyss of their own perceived shortcomings. They are often not at all bad people, but they have for one reason or another (perhaps childhood abuse or trauma) worked themselves into a mode of existence where they just cannot cope with any reality.

The problem with those who have been infected with PriSI syndrome is that it is a disempowering approach to life. Blaming others for problems seems to work in the short-term because PriSIs usually become good at emotional blackmail, and are rewarded when others take on the role of rescuer, and will always go one step further to satisfy the PriSI. But in the long term, victimhood does nothing but ensure that we can never live up to our full potential, because it prevents us from taking responsibility for the important choices we make, and holds us back from meaningful friendships and relationships because true love and true friendship require the common ingredient of truth, which cannot exist in the atmosphere of denial and distortion which is necessary to maintain the feeling of totally superior martyrdom.

In short, victimhood sucks...

Zippers and trains...

I have some theories about traffic flow mostly because, like almost all people living in sunny So. Cal, I spend way too much time stuck in it...

Billions get spent on highway improvements. Mostly this creates massive backups for a few years while construction drags on (for what seems like far too long unless you look at the entire project plan) and then things are finished just in time for traffic flow to get overwhelmed by all the development that has anticipated more people being able to get from point A to point B faster... you get the idea.

But a cheaper way of improving traffic flow is by changing driver behavior. I'm not just talking about the assholes who cut in front of you, taking advantage of your safe following distance, or cut to the front of a line of waiting cars, making traffic back up behind them in another lane while they wait to bogart their way in. The safe, considerate, responsible drivers can also make some small changes that could add up to massive differences. At some point I'm planning to create some software models that can quantify that...

So here they are:

1. The zipper rule.
Traffic merge happens whenever 5 lanes go down to 4 lanes, 4 lanes go down to 3, etc. The zipper rule is simple: one and only one car goes in front of you. Even if 80% of drivers "get it" and follow this rule, merges go faster. And this feeds into #2...

2. The train rule.
When a train starts up, it does so slowly. When a line of traffic is stopped at a light, it also starts slowly. But most drivers wait for space to be created in front of them as if they were driving at least 20 miles per hour. If everyone in line watches the light, and is prepared to begin moving, even if the initial movement is slow, the following distance can increase gradually. I'm talking about a big change, just watch the car in front of you and the car ahead of that one, and prepare to start moving at the same time as the car in front of you. It would be easy to model this and quantify the improvement...

Another day, another paper model...


Ha!

Take that, you compound stellated icosahedron!

You thought you would sit there and I'd refuse the temptation to put you together, but you were wrong!

I'm quite pleased with how this one turned out. I was testing a new feature of my Papercut software, which prints out the layout for assembling models like this. Pleasant surprise. Usually matching the tabs up is a pain, but this new version provides some useful hints. I still think it would be a cool party game, provide a group of people (drunk or not) with pieces and see how they do at putting it together.

Next cool thing: dump a big chunk of text and have it fill up all faces in a way that you can read it from top to bottom...
