Sometime ago I build with Rasbperry Pi detector of this if I'm using my desk in sit or stand mode.

It uses 2 ultrasound detectors, one is looking on ceiling, second is looking from desk in direction where I should be.

And it works :-)
It even sends me e-mails each day with info how long I spend sitting and standing.

And everything would be perfect... but sometimes something cause whole detector to hang.
It seems that somehow code doesn't return from GPIO reading.
And my detector stops to work.

I was trying to identify problem, but its rare and difficult to catch.
So I used other solution ;-) tested multiple times in microcontrollers...

I added watchdog ;-) if main program of detector will not report longer than 60 seconds whole Raspberry Pi reboots :-)

Math is stupid....

It is a chance that in July I will visit again Silicon Valley...
Important word is chance.

Still some decisions must be made. Budgetary decisions ;-)

So I tried to calculate how much it will cost to ship my team for 2 weeks there...

Answer is: a lot...

So I'm not so sure if I will visit my favorite part of US...

And everything because of math... and this that I can use it sometimes...

Meh.... Stupid math...

My way to (parital) vegetarianism

I always wanted to become vegetarian.
I will probably never become one on 100%, but I'm trying to go in this direction.

Only cause for me to want to be vegetarian is ethical.

I don't like idea of this that we need to kill animals to eat those, and lately I started also think about this how animals are kept.

Those are my causes. I think that other people may don't share my point of view. It is OK.
I may don't like it, but its theirs choice.
And too be honest I prefer those who prefer not to see problem, than those who try to rationalise bad things which are happening to animals.

But wanting to be vegetarian is one thing, going in this direction is different ;-)

So I started to practice kaizen vegetarianism ;-) I simply try to eat as much as possible dishes without meat :-)
Lastly I eat only pizza during our company Thirsty Thursdays, so usually during a week I eat meat once, or twice.
And it is working for me.

So if somebody want to try, this is quiet easy way.

And you always need to remember that soon, we will have cultured meat and problem of animals wellbeing will disappear ;-)
