Salesforce coding lessons for the 99%
Both have struck fear into my heart – in the restroom and in my code!
Enjoy life!

Great post..especially the Purpose has much profound influence on our success than the goal ..Thanks David , for the awesome post..
I feel some questions do not deserve answers, they are good as questions only and this one from you… such a thought-provoking one!
Great start of the day for me, indeed a good one David :)
In programming some languages make null the same as zero (C++) but some don’t (Java). In databases a record might have a null value in one field or it might have a zero and these are not the same. Zero is can be used to indicate a counted quantity whereas null cannot.
Null is the value given at instatiation before initialization and will result in Nullpointer error if used. Zero is a value. That’s for variables.
That is a thought-provoking visual!
In the world of Seinfeld, it’s the same… you “don’t have a square to spare”.
Thanks for the laugh!
I always thought the question was…What’s the difference between blank (“”) and null.
I love the sticking metaphore. One understands it for a lifetime. :)
A value vs. “”
Appreciated this SMILE
“Null” is blank, Zero has one digit “0”
