An alternate take on availability numbers

The usual way of presenting availabilitynumbers is to cover how much (or how little) downtime you have per year.As another way of understanding them, let's turn that around and ask howmuch less downtime you have as you move from one availability level to ahigher one.

90% to 99%two hours less in a day
almost 33 days less a year
99% to 99.9%three days less in a year
99.9% to 99.

保安

我本身並不討厭保安,在時代廣場也見過一邊執行任務一邊叫人join我地跳大繩的保安叔叔,但以下所見的保安並不是那麼可愛。

明日的記憶


我的祖母患上老人痴呆症已經有十多年,我對這種病一直有不一樣的感覺。

離港數天,回到家中,當然有好事發生 —— 我的Mint雪紡上衣,衫身短了兩吋,衣袖短了吋多,更變成了長短袖。

夠不夠諷刺?一個腰傷久久不癒,已經像半殘廢的人,再穿上這件上衣,可以扮演傷殘乞丐去行乞了。
