Divorce is hard.

I stand today in that precarious position between a relationship that has been failing to be of use to either participant, and a tidy divorce, with emotional closure, legal and physical separation.

The month we started fighting – once ‘divorce’ was a threat used by both sides in every argument – was a far harder time for me than now. And I’ll need to go back to describe that time. Right now I’m living with a friend with many shared interests, enjoying the attention of several women, biking and running daily, taking care of myself physically and in my job – it would seem I have it all together.  I do have it pretty together. I have learned to not let the foundation of life be unsettled, to value myself. Nonetheless..

This phase is marked by contradiction.. I’m together vs. I’m sad. I want to create a divorce settlement that will not keep my ex from being my friend vs. I need to stand up for my own interests. I want my (ex) not to hate me, vs. I can get my needs met elsewhere, and don’t have to spend time with her. I want this over quickly vs. I don’t care if it takes forever.

One of the last comments she said that I felt accused by was that I was always changing my mind. I want a divorce vs. I don’t want a divorce. Of course, she ‘s guilty of the same, but this does not invalidate her being hurt by ‘mind changes’. It does point out the uselessness of calling someone a ‘hypocrite’, especially in emotionally trying times. The same goes for the accusation ‘selfish’. Someone may feel their needs are hurt by anothers selfishness, and this is usually what is implied by that attack. But as the reciever of such an attack, I’m under no obligation to engage, nor to help the communicator say what they mean. I can walk away, or counterstrike as needed. But I will never answer a charge like that again, not with a straight face :)

I’ve recieved alot of emails from her (my ex) asking to do this or that – to tell her this or that. My own habits try and tell me to respond. A real desire not to disappoint, or disrespect – to be agreeable – you name the identity issue that comes up for me, I’ve felt it.  And yet to accede to these demands is to train a person that I am controllable through demands. I’ve stopped responding to them. It breaks my heart. But it’s time to engage my brain to keep me safe.

I hope it’s much simpler than Im making it. As long as no incoming communications are piling up, I don’t feel bad. And I have time – time with my friend, time with those who I call/who call me/who I want to see/who show genuine concern for me or excitement to be with me. It’s so good to have support, to feel in control of my relationships again. I dont’ have to apologize or justify or try to ‘win’ an argument. I’ve learned I can walk away from a fight, if the fight is not one that can produce gain for both parties. I can walk away from any fight. And if forced to engage, I can engage knowing that I exhausted all measures.

Every time I try to enumerate our assets, I stop, emotionally overwhelmed. I have a real block at this. It’s so backward-looking, which I hate in this start-my-new-life phase. On the other hand, when the court date comes, I need to know what I’m claiming I’m entitled to from our marital assets. It may not be 50/50 – it may be less which in some ways would be more fair due to incomes – but it will be more than the slap in the face amount I was a few pen strokes away from settling on, when a stupid comment caused a blow up, resulting in us both obtaining lawyers.  Calling bullshit on the settlement that was at hand that night may become the most costly argument my ex ever started. It certainly is the last I was to fully engage in with her.

It’s hard acknowledging that even my siging away most of my stake in our marital assets was unable to make a fight go away. I really had, and have, little control over whether I will be fought or not. But I don’t have to live in fear of it, and I can rely on my team to do most of my fighting for me. I have a new life to be building.

And I feel pretty good about doing it. There are so many adventures to engage in, self discovery to be done, and challenges to develop myself with. And this is one of them. And I do pretty well when faced with hard challenges, so BRING EM ON !

Transformative Growth

To help keep myself on the growth path I began early this year, a few summaries are in order.

I wrote (with my non-dominant hand) several things I like about myself. They are:

  • I am a leader in software/engineering
  • I maintain an athletic body
  • I am smart, and enjoy puzzling problems
  • I am good with people and make friends readily
  • I am creative and musically motivated

What I love:

  • Playing drums
  • Practicing karate
  • Doing it (to music especially)
  • Solving a difficult problem
  • Finding the words for something
  • Making people’s day
  • Getting carried away with someone
  • Beginning new journeys

My limiting, mistaken beliefs:

  • That I’m insufficient to relate to people
  • That I’m doomed to repeat parental cycles
  • That nobody will like me if I’m who I am (an only child)
  • That intelligence puts me on an island by myself

If coming up with these lists took a weekend – of tears, of being closer to my emotions than I ever was for a long time before, how can I get that back ? Should I go through another weekend April 1 ? Can I find a way to reinforce myself without these weekends ? Am I afraid of something if I only rely on myself ? Am I afraid the insights will be less potent, or I’ll use them as a crutch to not truly feel them if I get to the point where I can recite them by memory ? I think the last one has a point. Which is why, for now, I want to remind myself by looking at my notes, and eventually get to the point where I can simply recite all these hard-won statements about myself in under 2 minutes.

Self-knowledge is one of those things where the destination is less important than the journey. But surely the nuggets of truth found along that way can be saved, cherished, shared, kept in the forefront of the brain, and not buried, left to be discovered anew with the same amount of effort. Letting them sink below the sand is a disservice – I can build castles to show that I value who I have found myself to be.

People will see that I am living a righteous, courageous, striving and balanced life. I have not yet made an impact on the national, let alone world-wide scale, and I would like to. Yet I can be honing myself in my current environs and owe it to myself to prove my ability to effect change in the circles I frequent. Work is a great example where I can be boring job-getting-done engineer or I can be exciting leader, and curious learner. I can connect with people outside their default, guarded  ways of being. I can be someone exciting and creative. And I can troll my nets widely to catch people who ‘get it’ and create my own dream team.

It didn’t take the Wright to bring me to this. But the Wright did serve to shake up the box and allow me to resort this stuff out. Sometimes you have to allow entropy to break it all down, so that you can do the meaningful work of putting things back together, to include only what you really need. Peace and love and growth, Dean

Misconceptions about running faster

I don’t want to rant, but the preponderance of misinformation about what makes a more efficient running stride can drive a man to the point of insanity !

One doesn’t need beyond a 100-level college physics course to demonstrate that certain claims made in such books as “The Triathletes Training Bible”, quoted below, or various Pose-system explanations, not quoted, are consequences of models which can be shown to be inconsistent with the basic laws of Newtonian physics, which are here on Wikipedia and which are, briefly:

    An object at motion tends to remain in motion at uniform velocity
    The change of speed (acceleration) is proportional to the force applied
    Every action has an equal, opposite reaction

and the law of Conservation of Energy which states

    Energy can neither be created or destroyed: it can only be transformed from one state to another

The books are not to be dismissed outright – the charts and models presented in the book can save you tons of time of trial-and-error in building a training program. However their presentation of the mechanics of running is seriously deficient. At this point I have not tracked down the mistaken concepts to their sources, however the claims in the Triathletes Training Bible that need refuting are:

      Page 191: Whenever a support point is placed in front of the center of gravity, forward movement is impeded. It’s like hitting the “brakes”.
      Page 192: The energy stored by landing forward on the foot must [should] be converted to horizontal, not vertical, movement
      Page 190: An idealized runner is like a rolling ball [the 'falling' argument]

The way I prove my case is by appealing to the law of the conservation of energy, examining as a visual example, the case of an olympic pole vaulter. When she vaults up, the forward kinetic energy of the runner is perfectly converted to potential energy due to gravity – when she lands on the other side she has restored her horizontal velocity that was ‘lost’ at the peak. Does she arrive on the other side any slower or faster than if she’d just ran ? No ! The reaction force of the earth pushed her upward, gravity pulled her downward – but nothing acted against her horizontal motion ! Her speed relative to the air picked up when the pole threw her – but her average speed on the ground was constant. This means that bopping up and down has no effect on forward motion (except for the effects of heat, and muscular exhaustion) ! The force of the ground against the runner forces her upward, adding vertical velocity to her horizontal velocity, changing her vector so that she travels against gravity and changes her kinetic to potential energy. But when she falls she converts that energy straight back, and the amount is conserved ! Well mostly..

There are losses of two types to consider – but neither of them adds up to any defense against the above refutations – I include them only for completeness.

    Energy lost to ground, air and internal friction
    The opportunity cost of a more efficient response curve within the individual’s body

If a runner has 20km/h speed and 80 kg – even if they are internally efficient in moving along – is expending energy to move air molecules out of the way, which turns into waste heat. I’m not certain where internal friction in the body ranks, but internal friction in the body contributes as well. But these factors are small and do not support the claim on page 192 that over the course of a 10k a 150 lb person does the work of raising 84 tons one foot high. I’m sorry, but weight moving up and down equal amounts over the race, does no total work against gravity !

Energy is neither created nor destroyed. Energy leaking out as heat is a loss to the runner, and their only enemy. But an object moving up then down in a gravitational field is not losing anything on the balance. Even in non-ideal circumstances, every calorie burnt by cellular metabolism is going towards heat production of some sort for *the entire duration* of a race in which the net change in height of the runner’s center of mass is zero, and the velocity is uniform (aka inertial or ‘at rest’ motion).

What does matter, for any given runner – is what stride is optimal for their unique body at that time. Our skeletomuscular system is not perfectly elastic like a golf ball bouncing nearly is – so we make up the difference with cellular metabolism. These are the well-timed exertions that ‘keep you running at the same speed’. Ironically, these exertions create nothing but excess heat, in your body and in the air molecules around it – they are not used to move you forward, since inertia takes care of that quite nicely ! You only need to pay the toll on each stride for your body not being a perfect machine. The extent to which it is not perfect, and how certain stride patterns work around the worst imperfections in your body, may lead to your optimal stride being different than another persons’.

The important takeaway is that there is no physics limitation on one stride vs another, and the attempted justifications of one technique over another in appealing to fundamental laws of physics is flawed. I do believe you should try all kinds of running techniques that more than a handful of the pros are using. And read Born to Run and play with all that. But forget the absolutism of any single advocated technique.

Karate Promotion – Facing Down Fears

The night after my promotion exam for 7th kyu (advanced blue belt), I had no idea I would be faced with a self defense challenge, with a knife held 2 inches in front of my face by a former boss of mine. He’d just tried to humiliate me, and drew the knife when I resisted crumbling to him. This was in a dream, thankfully, after I fell asleep on the couch after the exam. The emotional part of the dream was entirely real, and I believe the confrontation was the final aspect of my promotion test, which I’m glad to say I passed.

I was looking forward to the promotion exam, but as I was asked to demonstrate some of the weaker parts of my training, I nervously looked at senpai who I did not want to disappoint, and I grew increasingly nervous. Kyoshi’s reminder to be less tense in order to generate speed was well taken, but I was unable to fully act on it. I was sweating heavily, as I figured I should have been, but it was only when I got to take a break that I was allowed to understand my true inner state. Senpai Sarah Kranz – who I think has the emotional and physical intelligence to lead a voyage to Mars – looked in my eyes and asked if I was ok. I said “Yeah, sure”, and she persisted to assess me, and asked me to go splash some water on my face and arms.

What I saw when I went into the bathroom was my pale, pale face, with cold sweat and reddish eyes. I looked unwell. What emotion causes blood to leave the extremeties and pool in the core ? Fear. What was i afraid of ? I was afraid that I was not doing my training justice. I was afraid I’d not have earned my belt. After addressing the physical manifestation of fear with cooling water and deep breath, what did I do ? I gave myself a pep talk, and thought about what Senpai Kate told me – how I’m not being judged, and that feedback is meant to help, that all the senpai have made mistakes before, and that I should be proud that I am doing my best. Being afraid was holding me back. So I decided I would not be afraid, I’d embrace my mistakes if they came, and I’d continue the exam..

Fast forward to the dream. My former boss was in my dream, he had just tried to humiliate me in front of a lunchroom full of people. When I challenged him on the nature of his grievances, he cleared the room, save for a sycophant or two of his. I was alone and outnumbered. I was afraid, as in the exam. Then, he escalated. He started “You know – ” and during the next few words drew a large kitchen knife from a table and shoved it squarely between my eyes one inch away from the bridge of my nose. I froze and went pale momentarily. Then the worst thing happened – I woke up !

How did this end, I thought ?! How could I have let myself freeze ? At that point, I realized I’m still in the dream ! I was physically awake, but I could see the situation frozen in time in front of me. Remembering Shihan’s counsel, I started moving back and raised my voice – “OH MY GOD **** (boss’ name) WHY ARE YOU PULLING DOWN YOUR PANTS THATS RIDICULOUS” I was reaching out to potential onlookers. I also started recalling my physical defense options – getting inside the knife – taking one hit on an arm in order to deliver a disabling strike to the eyes or throat or groin with the other hand. Throwing books, chairs, running away. A knife pointed at the face is intended to cause somebody to shrink or freeze. I would refuse to freeze, from the moment I felt that fear, I would refuse to let it paralyze me. As I realized I was fully awake now, I knew I had met the challenge, and I could proudly approach my day – a tremendous contrast to the helplessness I felt when I first ‘woke up’.

I earned my belt in the examination, but I earned something greater when I faced my enemy down and found my voice and power to remain fluid and unstuck. Thank you Senpai for contributing to my growth – it literally was with your words in my mind that I found the tools to do what I had to do.

Musical Leadership Adventure at Old Town jam

Today I went to the Old Town School for their midday jam, bringing my banjo.

After several songs of either playing along quietly, singing light harmonies, or lightly drumming on the banjo head to a tricky-to-count-to waltz Scarborough Fair, I finally got the nod from the group leader to do a solo. I held on to the rhythm, assertively plucking though my fingers were starting to hurt in the pre-blister way.. I’d played earlier in the morning and was in a good mental state to play, listening inward, but projecting outward.. It was nice, and I wrapped it up on time, and handed off to the next guy flawlessly if I must say so my self !! It was a thrill to get the nod – as ready as I thought I was, it’s a whole other level of nerves when you get to know you’re up next and have only a bar or two to get ready – that’s why we do this isn’t it !! =)

There was great camraderie and joking in the group – a female fiddler and mando player held their own and joked like ‘one of the boys’. The kazoo player got the most crap actually.. A harmonica player kinda made me cry with one of his solos..

I got a second solo later – maybe it was Roll in My Sweet Babies’ Arms – this was a more bluegrass finger pickin roll song and I just went inside, controlling my breath and maintaining that fine balance of tension and relaxation that allows for fast but bright picking. I made it – got the nod for a second go around – and went to a higher brighter neck position – I was pretty ecstatic by the end of it and finished my second chorus with a few loud strikes to hand it off. Bliss !! Before I knew it I’d spent an hour and a half there !

I got the chance to call a song too – which I stepped up to. I’m aware I’m alot younger than most of the jammers there, but that’s part of the fun of it. As long as I’m trying to have an authentic, supportive experience, there’s really nothing people can do that will knock me off my game. One guitar player who ended his solo with an I’m sorry to the group (never apologize for trying and learning !) got a big smile and thumbs up from me and ended up tearing the song a new one on his next solo as well as helping me anchor the first song of the jam after the teacher had left.

It was a great time. I miss those challenges – I gotta make sure to do this regulary. It’s a necessary part of my develpment as a musician !

More Life Training Synopsis

I went to the Wright Institute’s More Life Training weekend this weekend, at the invite of an awesome FOAF I’m getting to know. I won’t summarize what happened – I’ll describe my first day back, and from it I want you to understand that I think it can be a transformative weekend for you as it was for me, if you take a chance. I have no regrets about having went, and a lot of gratitude for those there – who I am now going to incorporate into my ‘Dream Team’ – for unlocking doors in myself that have long since been shut.

My karate class – I felt good, physically present – and when it came to partner exercises I felt more able to send energy to my partner, and watched as they literally did more, faster, or stronger strikes on the target pad I was holding, with barely any vocal encouragement from me at all. At the end when we did a supposedly closed eyed meditation circle, I discovered later that another person was cheating- a young person I don’t know the name of and haven’t had more than a few words with, and we made lasting, meaningful eye contact for nearly a minute until we both returned to our eyes being closed.

After returning home later than I thought, my wife had gone to bed, and I put my karate uniform in the wash, and chose to play some Pac Man as a diversion, since I’d been pretty much working all day since I woke up. I said I’d keep it to one game – I sometimes use a game of Pac Man to measure my state of mind. I got 19,900 that game, dying with only one dot left on the 2nd board, and getting a couple of 4 ghost runs. A usual first game score for me is from 9 to 11,000. I decided to push myself to another game, not just to beat my score (I was sure I’d beat it) but to work on an intriguing aspect of the game I discovered in the first game, and thought I wanted to expand upon in the second game (the ‘inside’ game). I made it mostly through the 4th board – got around 27,000 (my record is 33,000 and the 6th board), was not surprirsed that I beat my score, and then turned off the game as I promised I would.

The washing machine is still going, and I’m almost done with this post..

My conversation with my mom between karate and pacman was good – I won’t go into detail, but I felt very present. With Maria the night before, and during our lunchtime conversation, I won’t say it was without tension, but it was a tension around very honest topics we both wanted to work through.

When the phone rang today, I picked it up (not usual), if I was busy I told the person that, and then asked them why they called anyway and had a few good words. I checked my email twice, responding only to the 2 most important ones.

I have a good degree of focus, and I really believe in myself, and that I will have good conversations and progress at work tomorrow.

The story I want to sum things up with is this – Roger Bannister was the first man to run a 4-minute mile: http://en.wikipedia.org/wiki/Four-minute_mile. The year after he achieved this (1954/55), 15 other men broke through that record as well. They believed it was possible. If seeing is the only way you believe something, you certainly will not be the first person to go somewhere new. But the point is not that skepticism is bad, but that the difference between thinking “I’m doing my best” and actually doing your best, the level which you don’t know is within you, is both in believing that a higher level is possible, and believing that you deserve it and can do it. Sometimes, cynics, belief does make all of the difference, and if you haven’t had that experience yet, please talk to me or somebody to seek out somebody who can help you.

There’s the laundry clicker. Gonna sleep long, deep and hard tonight. Peace,

Dean

Smart Partials aka Web Parts – a complementary approach to MVC

Smart Partials

I shouldn’t procrastinate doing useful work for too long to write this article, so I’ll keep it brief..

Here I declare a pattern – distinctly different from MVC, but still useful in rails or other app frameworks – which I’ll call Smart Partials. It lifts itself wholesale from other frameworks where they may go by the name Web Parts, etc…

I’ll explain it in contrast to rails MVC principles, in a way to hopefully overcome any objections its adherents might have.

Partial: accounts/_account.html.erb
<% if account %>
<%= account.name %>
<% end %>

Typical Rails MVC would have this be an @account variable, would require controller code to populate this variable, or would expect account to be a local variable to the template.

This is not what I mean by a Smart Partial – in fact demanding that those up the stack from you have to do more work to use you is the opposite of what a good component API ought to do.

So how do we reduce the burden on callers, while still ensuring the view does not contain any real ‘logic’ ?

In my example, I use the fact that in Ruby, ‘account’ may refer to a local variable OR a method. We know these methods that are intended to be invoked from views to be called helpers.

Helper: helpers/account_helper.rb

def account
if id=params[:account_id]
@account ||= Account.find(id)
# you may have other ways of fetching account_id - from a cookie, from a param of a different name, etc..
elsif id = request.cookies[:favorite_account_id]
@account ||= Account.find(id)
end
end

A nod to: http://www.stephencelis.com/2008/09/06/rails-controllers-views-and-variables.html

The main selling point of this approach is that it does not impose a burden upon controllers to populate variables. It increases reuse, reduces boilerplate code. It ensures that at the last possible moment that the account variable be resolved, it is resolved if it has not been resolved already.

Some people may prefer the helper method could return @account early if that is already populated, which is fine – the helper is a smart obtainer of the account – whatever those smarts mean to you, by all means put them in..

This arose because I felt that using the MVC pattern dogmatically to the point where you can’t author self-contained view components anymore – sucks.

Let’s be OK with using Web Parts or Smart Partials in MVC web frameworks.

You may find like I have that the benefits of being able to build web pages by composing self-contained parts outweigh the comfort of the old coding habits.

Try it and see.

Pose and running and the heel vs. toe debate

Pose and barefoot have influenced my running to great effect – but the premise that landing on a heel by itself creates a problem is flawed. Check out Usain Bolt here http://www.codinghorror.com/blog/2010/10/the-keyboard-cult.html – He’s landing heel down, in front of his body. Contrary to the triangle-stability metaphor, the pole vaulter’s metaphor is more fitting. Your forward momentum will slow down, as you change -> kinetic into ^ potential, which you release in your next step. You can’t fall forever, and energy is always conserved (less friction aka heat). When I was running on ice last night it occurred to me that one thing Pose is good for is just that – you won’t slip on (non-wet) ice if your feet are mainly pogosticking up and down, pushing -> only as much as needed to restore intrastep losses. And if you get up near 180 steps / minute, that’s not much ! So I’m grateful for my lessons, but want to keep the mental model clean and shiny.

Coding Katas, and kata in general

Hey – just saw this thread and wanted to share 2 cents on coding ‘Katas’

In martial arts studies, Katas serve a couple purposes:
- they are intended to be repeated many times
- they aim to develop ‘physical’ memory (not judgement, which is built later in other manners..)
- are developed incrementally from simpler katas
- they are trained in terms of what they are (punch low) rather than how you apply (disable the attacker)

The coding katas I see at (http://codingkata.org) are interesting challenges but they need a somewhat creative approach, and once solved – who wants to go back and do again ? This misses out on the repitition and incremental development aspects of kata, as I see it..

For the roman numeral conversion problem, the kata student would first demonstrate proficiency in other number conversion routines (base 10 to base 2, base 8 to hex, etc.), then top it off with the roman numeral version which is a somewhat special subcase of the number-conversion problem class. Mastery of the whole problem-class is the goal, and the arabic-to-roman routine should fall out of the programmer without much ‘thought’ when they have been sufficiently ‘trained’, as it would be similar enough to already-demonstrated concepts…

Hope this adds another option to how to think about skill-building stuff, based on my learning experience in some methodically/physically trained disciplines…
