Here’s life from Geir’s point of view:
Not even close to complete or even correct, but it’s a start.
Happiness is not a state.
Happiness is growth.
The derivative of happiness is not zero.
The derivative of happiness is positive energy.
My requirements: Being able to do astronomical calculations while observing through my telescope during cold nights while not hurting my night vision.
With a smart phone, I’d have to use touch gloves or take off my gloves to press “buttons” on the screen. And then I’d have the hassle of filter programs to dim the screen and make it red to keep it from impacting my night vision.
With my HP-41, I’d have to use a led light to see the screen.
But with an old red led calculator, I could get all my requirements at once. Except there are few of these old pre-1980 calculators that would be capable of doing all the calculations I need; Date -> Julian Date -> Date, Sun rise/set, Moon rise/set, Moon Phase, Field of View calculations fro various eyepieces, etc. Fiddling with magnetic cards for the HP-67 would not be ideal.
HP-25E to the rescue! Bernhard Emese (Panamatik) has created a true piece of art with his “brain transplant” for the old HP-25 calculators. His HP-25E boast a 100x increase in programming memory, on-board GPS with time, Latitude, Longitude, heading, speed and more as well as a stop watch, chess clock, hexadecimal conversion and much, much more. It’s the ideal calculator for my requirements. Except it still had only 50 program steps memory per program. Although it had the possibility of storing 100 HP-25 programs in a constant memory (not lost when you turn the calc off – unlike the original HP-25), you couldn’t write programs with more than 50 steps. And this was way too small for the programs I need.
Talking to Berhard about the possibility of “stringing together” different “pages” of 50 program steps, we came up with a neat way of solving this issue. By using some available rare codes, the HP-25E can now jump between various programs – potentially creating programs with thousands of programming steps.
And so I embarked on the journey of creating the AstroCalc – the ideal tool for the amateur astronomer. So far, the GitHub repository only includes the calculation of Julian Date from a date and time and the backward conversion, from Julian Date to date and time. With the HP-25E’s possibility of constantly updating the time, this makes writing down the exact Julian Date on my observations a breeze.
I will add the Sun/Moon rise/set, Moon Phase and eyepiece calculations soon. Just check my HP-25E_astro Github page for updates.
I fucking love this calc.
Business people, salesmen, game theory mathematicians, Donald Trump and negotiators would advice you to get the best deal possible. And the best deal would often amount to getting the biggest share of the pie that you can possibly get.
While that strategy may get you rich when selling refrigerators to Eskimos, it is not the best long term strategy for a partnership.
Whenever you try to get a bigger piece of the pie, the other parties gets less. And their motivation for baking pie suffers proportionally.
Trying to get the “best deal” by getting an unfair portion may be a viable short term strategy. But in the long run it kills partnerships.
The best way to ensure affluent pie making and long term profit is for every party to insist on a fair deal for everyone involved.
The best strategy is not to simply cater for one’s own interests. It is to cater for everyone’s interest. Putting my interest first hurts the other parties’ interests and kills off that much motivation to make the partnership work in the long run.
The best strategy would be to impress as much as you can by delivering value to the partnership as often as you can. Give life to the partnership by continually giving and insisting on a fair deal for everyone involved. Empathy, transparency, putting all cards on the table and dropping all chess gaming are keys to a good partnership. Don’t do tactics. Don’t do strategies. Just ensure everyone succeeds.
Here’s a really neat overview of mathematics. Enjoy.
“I am struggling in my job. I don’t know if I should quit my job or continue. And if I continue, whether I should focus on this or that or the other thing. Is this type of work even for me? I feel exhausted. Not much positive feedback, and I don’t really know if what I’m doing is valuable for the company, for any customers or for other employees. I feel kinda lost. What should I do?”
He looked at me across the table. Across his cup of coffee, and mine. I started out slowly:
“You know, there’s stacks of books written about this, countless methodologies and coaching practices addressing these kinds of issues.”
He looked eagerly at me, waiting for some book or methodology that would match his complex problem. Some kind of intricate way of resolving his issues. But then I went on:
“But really, it boils down to just one simple concept. Just one.”
He looked sorta disappointed. Like I was about to invalidate his complex problem or insult his intelligence.
“You only need to impress.”
“Yes, impress your customer, your boss, your colleague, your wife, your kids, yourself. But impress by delivering something of value. Impress your customers in every meeting. Impress your colleagues every workday. Impress your kids by really playing with them when they bring out the Lego. Impress your wife in bed. Impress by delivering. Unconditionally and as much as you can. If you do this, you’ll be doing good. And this is all you need to do.”
