it's a long time from the first the time when i created my bolg .but there no one letter !
i'm a lazy guy!
sometime there a lot of things (knowledge) you hava to remeber but you can't bear in mind! when you need it ,the only thing you can do is seach it google time and time . it waste me a lot time .and i don't think it is a good habit!
so i decide writting my bolg as offen as i can !
and practice my poor English level!
