RAID,全名為 Redundant Array of Independent Disks 是保謢資料的方法。
最常用的有方法分別有 RAID 1 及 RAID 5。
RAID 1 又稱為 Mirroring 即儲存至 Hard Disk 時,是將相同資料,同時寫入兩個 Hard Disk 中,當其中一個 Hard Disk 出現問題時,可以立即使用另一個 Hard Disk 補上。所以這種方法,必須使用兩個 Hard Disk。
RAID 5 至少要使用 3 個 Hard Disk,每次儲存時,會將資料及 Checksum 輪流寫入所有 Hard Disk 中。相其中一個 Hard Disk 出現問題時,只要換了有問題的 Hard Disk,系統便會從新計算出正確的數據,重建於新的 Hard Disk入面。

三思而行
每次開會,都好似打仗一樣,講每一句說話都要三思而行。只要說錯一句說話,隨時會跌入萬劫不復之地。亦要打醒十二分精神來招架不同的題問,所以每次開會,都會消耗極多體力。
而眾多對手中,我最討厭的人有三種。
(一) 不信任你而要你替他做事的人。
(二) 聽不懂你的講解,又要扮聽得明白,但之後要重複詢問同一問題。
(三) 幫他解決問題後,連多謝都不會有一句。但出問題時,便粗言相對,認為所有問題都是你的問題。
當遇到這類人,EQ 稍為低的話,真的很容易失控。
因此,我終於明白到,國家的領導人說話時,為何總是很悠閒、很慢。其實,他的每句說話,都是經過再三思想的。所以,我都要學習他的這個慎言行為。

Two less lonely people in the world
I was down my dreams were wearing thin
When youre lost where do you begin
My heart always seemed to drift from day to day
Looking for the love that never came my way
Then you smiled and I reached out to you
I could tell you were lonely too
One look then it all began for you and me
The moment that we touched I knew that there would be
Two less lonely people in the world
And its gonna be fine
Out of all the people in the world
I just can't believe youre mine
In my life where everything was wrong
Something finally went right
Now theres two less lonely people
In the world tonight
Just to think what I might have missed
Looking back how did I exist
I dreamed, still I never thought I'd come this far
But miracles come true, I know 'cause here we are
Two less lonely people in the world
And its gonna be fine
Out of all the people in the world
I just can't believe youre mine
In my life where everything was wrong
Something finally went right
Now theres two less lonely people
In the world tonight
Tonight I fell in love with you
And all the things I never knewSeemed to come to me somehow
Baby, love is here and now theres
Two less lonely people in the world
And its gonna be fine
Out of all the people in the world
I just can't believe youre mine
In my life where everything was wrong
Something finally went right
Now theres two less lonely people
In the world tonight
When youre lost where do you begin
My heart always seemed to drift from day to day
Looking for the love that never came my way
Then you smiled and I reached out to you
I could tell you were lonely too
One look then it all began for you and me
