time after easter

..it was a pleasant easter....had a nice time have pork...did not have to put too much pressure on my jaw to eat.....

then had a fantastic drive to chickmagalore....where my sis stays.....first of all it was a nice time with my dad...it had been long since i had spent good time with him....we did share a lot of things and finally it looked like my dad has a lot of faith and confidence in me....felt better.....

the other best part was driving...man it was a awesome drive....pushing my car to the limits...this was great...i think i made a cool decision to buy a indica.....this is too good for me.....

now back in office....waiting for the last day here....did not feel like wasting time...so decided to do some writing on the fav subject of mine.....LINUX...and this is what i am sharing today..have fun

since i have been workin in the embedded field...i have worked a lot on kernel tweaking and one main thing i was lookin at is the least amount of time the linux kernel shud take to boot and here is some tweakin that i am givin for x86 box....but on arm u dont see many of these scripts.... not much to worry abt....i shall be sharing other things related to what emebedded in the coming days...
