What is multitasking? it is the practice or capability of handling more than one task at the same time ..

It is said that our brain is capable of performing certain dual multiple tasks at the same time, for example, listening to the radio while writing an email, increasing the amount of tasks was one of the very basic reasons for inventing the CPU from the first place ..

Well, I completely disagree, actually there is no such thing as multitasking, only context switching which simulates multitasking, even for the CPU!
Let me explain ..

Human brain and CPU are quite different, our brain is more complicated, so I will take the CPU for an easier example ..
Consider that you need to perform 2 tasks on your PC, each requires exactly 10 seconds ..
The total time required will be 20 seconds for both tasks if running sequentially, first task will be completed after 10 sec and second task after 20 sec ..
But if you run both tasks simultaneously with the use of what called CPU multitasking, the CPU will do a context switch between both tasks, in other words, breaking down each task to segments and switch back and forth between them, assuming that each task will have 10 segments, each segment requires one second, then first task will be processed at odd seconds (1, 3, 5, ..) and second task at even seconds (2, 4, 6, ..), in that case we will have first task completed after 19 sec and second task after 20 sec, considering that the switch takes no time at all !!

Imagine the above procedure in our brain with the unexpected time required for the context switching, there is no accurate numbers but obviously the sequential approach will take much less processing than the simultaneous one, using only one switch between tasks !

On the other hand, human context switching (what I call distraction) means spreading attention among tasks, like talking on the phone while driving a car, since 2003 car accidents increased about 40% because of cell phones!

Observation:

• CPU can not actually perform simultaneous tasks, it uses context switching to simulate multitasking, even with mutli-core processors, yet each core still performs exactly the same.
• Context switching will not reduce the total time required for all tasks, it just adds an extra time for the switching operation.
• Multitasking more accurately refers to Managed Tasking!
• Human context switching consumes much more time than the CPU, in addition to the continuous partial attention.

Conclusion:

Never think or act simultaneously!

I can find no words to describe how I feel when I find my kittens asleep, very much like a calming potion ..

Zorro: abnormally active and extremely stupid ..

My kitty bit me while giving him a bath, my blood ran out of my vessels intensively, I hit him badly for that, I felt panic watching his left eye turning red from my torturing! what a sadistic person I am! I deserve a special place in hell I suppose! I really do!!
Next morning, he recovers extremely fast! and he came to me plays like he never did before! and he still does!!
But ..
My thumb doesn’t look that good, the swelling turned my left thumb to a mini red balloon, the pain is awfully annoying, now I’m taking all the bloody shots for Tetanus and Rabies, also trying to escape doctors who strive to trim that thumb out of my god given body! by having proper cleaning, treatment and medication, I hope that works without losing that thumb!
Who says that humans are the strongest creatures?! kill that guy for me please!!

For the first time I ask myself how to escape my great depression?! despite all what I’ve read about such emotional feelings, I still find it more like a lightening strike, we do not really know when it hits us ..

Who am I anyway, what really describes me best right now .. struggling between being plugged into technology and being shot into space .. living in a mad house in Egypt called Cairo .. hiding behind my mysterious imaginations .. and most of all .. suffering from a frequently brain-freeze status!

I used to believe that everything happens to me is because of some reason I’ve actually created myself .. I know that I’ve been buried between a keyboard and a screen for a long time .. and this is exactly what blocks my eyes from seeing so much in this world .. sometimes I feel like I can’t help it and I am addicted .. other times I feel like a prisoner .. how could I feel so much hesitation?

Hesitation .. I can’t ignore being afraid just by saying this word .. may be it’s my pride .. may be I’m writing this post trying to face it ..

I’ve always believed that there’s an answer to any question .. even if it doesn’t exist “yet” in human known history books .. even if it requires an extraterrestrial form of life .. and here I am seeking a new answer ..

Since my brain prefers the analytical behavior, then I might try acting like a seeker instead of talking like one .. and that requires taking off .. using my power of observation .. being exposed .. intentionally!
