The best offer i got from net is from DOCOMO.

for Rs 24/- STD at 1p/6sec with validity of 30 days.

AirTel
I am using AirTel - it doesn't have any offer.
Maximum they can offer is 1/- for 3min STD call.

Idea is almost similar to AirTel,,, no offers at all.
Idea Prepaid Tariff Plan
The best they have for STD call is charge for 61/- and get 140min free. :-(

Worst plan i ever see,,,

process memory usage in Linux

In linux, the amount of physical memory a single process might use 
can be roughly divided into following categories.

* M.a anonymous mapped memory
  o .p private
    + .d dirty == malloc/mmapped heap and stack allocated and written memory
    + .c clean == malloc/mmapped heap and stack memory once allocated, 
                  written, then freed, but not reclaimed yet
  o .s shared
    + .d dirty == there should be none
    + .c clean == there should be none
* M.n named mapped memory
  o .p private
    + .d dirty == file mmapped written memory private
    + .c clean == mapped program/library text private mapped
  o .s shared
    + .d dirty == file mmapped written memory shared
    + .c clean == mapped library text shared mapped

m.a.p.d
awk '/^[0-9a-f]/{if ($6=="") {anon=1}else{anon=0}} /Private_Dirty/{if(anon) {asum+=$2}else{nasum+=$2}} END{printf "sum=%d\n",asum}' /proc/<pid>/smaps

m.a.p.c
awk '/^[0-9a-f]/{if ($6=="") {anon=1}else{anon=0}} /Private_Clean/{if(anon) {asum+=$2}else{nasum+=$2}} END{printf "sum=%d\n",asum}' /proc/<pid>/smaps
