股市：
幾時入市？要等基金震倉潮完畢方可入市。不用猜恒指跌到幾點，只要看兩點
1）當日元“穩步下跌”，代表carry trade應該全部震完
2）當libor 下跌至正常水平
預算要到明年初

無聊而上網亂逛
看了張如城先生的這個訪問
主持人和被訪者都認真得搞笑

也不知是什麼原因
其實我是有點佩服城城的
他敢於做自己
而且他有他的成就
我們笑
是因為我們都無法表達這樣的自己
張如城是好樣的

Our old SAN was set up in the traditional way: the SAN backend units didRAID-5 interally, and this RAID-5 space was carved up into LUNs and usedby the frontend fileservers. For natural reasons all of our fileservers wound up using LUNs from all of our SAN backends.This setup has low overhead , decent resilience,and decent performance.Our new fileservers are set up inan entirely different way, and among other things they use RAID-1instead of RAID-5. Although we were

After finishing my round on a Saturday morning, I was about to leave the hospital. I then heard someone calling my name, and it turned out to be an old friend of mine.

There followed a five-minute conversation starting with "What do you do?" on the corridor. This familiar conversation opener, whether you like it or not, is everywhere around us.

The way we ask or answer this question simply reflects how we identify ourselves in terms of the work we do. In virtually every society

How we worked out the partition sizes for our SAN

Wandering Thoughts | Oct. 25, 2008, 1:18 a.m. | Original

Our new fileserver setup requiresthat all of the LUNs exported by the backend SAN be exactly the samesize, down to the block, so that we can always mirror two arbitrary LUNstogether. We wanted our basic LUN size to be around 200 to 250 GB, butthat's a large range of possible sizes, and it still left us to pick asensible exact block size.

Our first approach was to take our 750 GB Seagate SATA disks and dividethem up into three equal
