The beginners dilemma

JChristensen

Haha, but also happens to some non-beginners too  ;)

My programming instructor once said to me, "It's a miracle that any of this stuff works".    :~

I find that, after making changes to code, if it successfully compiles the first time, I probably messed up something in the Makefile.   :smiley-sweat:

AWOL

A lot of it still is pretty miraculous, when you think about it.

I've just done an Android build - the Linux C source alone (*.c plus *.h) runs to 168 000 files.
The build kept a quad-core (with hyperthreading) 2.8GHz Xeon busy for the best part of an hour (the time for a single core is about six hours).
And yet, at the end of an unimaginable number of complicated actions, I have a working image ready to flash into a device.

It is lots easier to know why it doesn't work than to know why it works.

I'm still baffled by those things. For instance why does my sliding door slide lots easier when I spray "the hard to reach nearly fully enclosed wheels" with WD40?  :smiley-eek:
I mean I have to drag it before spraying and when I sprayed it I have to stop it smashing in the lock.  :smiley-eek:

Just like this:-

yes, exactly
And both methods do work (short time) :-)

Just like this:-


I am going to print a modified copy of this and hang it in my garage, with arrows pointing down to the requisite items on a shelf.

WD40 is not oil. Too many people treat it like it is.

Correct.
And the "WD40 company" thrives by that, as you will need to reapply it over and over again, until something is dissolved too much, and fails forever.
Have a look at "blink without delay".
Did you connect the grounds ?

Hi, now if it wasn't for the nuclear industry we might not have WD40.

That's not what the Wikipedia link says.

"WD-40 is primarily composed of various hydrocarbons."
"The long-term active ingredient is a non-volatile, viscous oil which remains on the surface, providing lubrication and protection from moisture."

They state the MSDS sheet says "<25% petroleum base oil, presumably a mineral oil or light lubricating oil."

You have other information?

My experience has been that there is so little "long term" ingredients in it, that for 99.99% of the purposes, it might as well not be there.

Why go to Wikipedia to read what someone else says about the MSDS?

I've seen hinges destroyed with it, because it washed out the original grease and what it left was insufficient. I've seen rotating bearings destroyed for the same reason. I've seen potentiometers and switches ruined by it.

It has its uses. But in my experience, it sucks as a lubricant except only temporarily.
