Of snips and snails

A day of revelations it certainly is.
It so happens at times that your mind just refuses to work.Refuses.To.Work.
With me, it particularly happens when I am sitting in the dreaded examination hall.
(Now, some people may argue here that it does not work , given any orientation of the sun and any orientation of the moon.But people will always be saying disagreeable things.)
On with it now.
Since I have to sit there to take my exams, it is some thing in the nature of a problem for me.
You see, I need these flashes of imagination for-everything.People get them at times, mostly as intuition. For me, they are necessary. They are the only way my mind works.
Once I wrote about how, at times, you seriously, badly, really need to kill someone. At times, you badly need to kill yourself, too. Like they say in our country "If you remember it after the quarrel, slap your own face". Likewise, the flash of mind that comes when you have left the examination hall should be made to carry a very high voltage and then descended upon your own self.
After wondering so much about the way it happens, I should come around to what actually happened.
What actually happened was this: I sat brainstorming for some half hour, contemplating the problem of excess three addition.
Nothing came.
A blank mind.
Excess 3?What the hell? WHAT THE HELL?
That part was ok. I know quite well that logic is Not the thing for me. I would have done well in a subject called , say, Imaginative Fantasy design.Digital logic just gives me the horrors. Shudders and creeps! It is a nightmare, and I have learned to live with it.
No, the bad, or worst, part came the next day. I had not been thinking about it at all. the flash of  imagination, or the flash of logic, came the next day. the next day, as I stood brushing my teeth, I suddenly saw that excess 3 decimals fall in a modulo 9 scheme, and so, like BCD, can be corrected simply by adding 6 to the sum whenever it exceeds 12.
I could not have been thinking about it at all, as I had just got up.If anything, I was thinking of getting some more sleep, and whether I should go to sleep again right then.
Definitely not excess 3 code.
Now, I am seriously thinking how these flashes can be made to carry high voltages and them descended upon my own humble self.
Maybe I should carry my tooth brush to the next logic paper.It may know some.
I certainly do not.
About the title-yes. It is a nursery rhyme I first read in an Enid Blyton book. I have modified it so that it says:

What is digital logic made of?
Snips and snails, and puppy dogs tails
That's what digital logic is made of !"
What is programming made of?
"Sugar and spice and all things nice
That's what programming is made

The time to kill

I should not be here, as I really intended the last time I blogged. Till an hour ago, to be exact.
However, I need to remain alive and sane more than I need to pass the exams.So I come here,
The theory of evolution implies that you have to compete in order to survive. At times, there may arise a situation where you can survive only by killing your opponents. If there is a single goat and two ravenous lions, one of them will have to kill the other in order to-live.Of course, this problem confronts other members of the animal kingdom. Homo Sapiens, thankfully, have, and can produce, enough food.
Goats are very seldom the bone of contention between human beings. What really makes one want to kill another human being is his or her behaviour.(By the way, behaviour makes me wonder why the Google people are so obstinately American)
At the moment, I feel that I would love to murder some one. Well, I might die to murder some one. This some one can be any one from the rotten administration. Murdering someone , anyone from the extraordinarily admin would give me the relief I so badly need. Relief I badly need in order to withstand exams delayed at the last night.
In order to survive, I need to kill.
