It finally happened

[OperaHouse]

I finally designed a system even I don't understand. I plugged an array into the wrong connector after driving all day. I thought it was a 3P and last year I had changed it to a 3S. 60V into the 12V electronics and it burnt up the microprocessor etc. It then took over two hours to figure out where I was supposed to plug things into.  I run strings of four different voltages.  It was all just temporary till the new system was created. Never documented it because it was so simple. I was able to find another micro and carefully wrote down where the wires went.  Then it took an hour to find the pesky little white wire that hid itself.  I had counted the number of pins from each end as to where everything went.  It took forever to figure out this clone had two extra pins than the last one.  The damage will run into the high single figures.

When I write programs I always document them as I go - as if it would be worked on by someone else some day.

One reason is that, if they ever need a fix or upgrade, the version of me that has to do it will be a later rev than the one that wrote it, and won't have all the information "in memory cache" that the version writing it had.  B-)

At least you guys can theorize, program, design, diagnose, document...I get distracted on my way to the shop picking things up in the yard, and end up forgetting what/why I went out there.  Sometimes I have to come back in and wait for it to come to me.

And I thought I am the only one suffering from this.

Back in the early years of this millennium, there was  a real study done.
It proven that men can only remember 4 things at once, sooooo.
IF you're given more than 4 at once and only 7 things to do in a given day, somethings gotta give.
That's what I tell everyone who asked me why I forgot,,,,,

The "cardinality" count I recall (from the 60s or so) was 6 to 7.  But that's for what you can think about at the same time / rapidly switch among, without boggling, not for what you can transfer to memory without dropping one of the other plates.
