[Marathon] 第六屆台南古都馬拉松 12-Feb. 2012

這次的全馬算是最順利的一次....

20公里內都在肌肉能負荷的情況下....

大致跑了 2:20 ....

過了20公里....

一些平常沒在訓練的肌肉就被拿出來用了....

像是股二頭肌, 半腱肌, 半膜肌, 臀中肌, 臀大肌, 髂脛束......(我抄網路的, 有錯請更正....)

很怕受傷, 就放慢了速度....

目標只要能平安跑完全程就好....

這個時候遇到了 Holy Allan....

邊跑邊哈啦....

大概一公里後我就追不上了....^^

望著那神一般的背影....

說聲 byebye.....

一路跑到30公里....

半腱肌實在是痛到不行....

就開始停下來用走的....

這時候就被一堆人輾過....

包括三超人....蝙蝠俠..蜘蛛人..超人....

走到最後 4 公里的時候....

百馬陪跑團上來了....

陪跑了 1 公里....

這時時間是 4:42....

心想這次不可能五小時內了....

那就........輕鬆走吧.....^^

回到終點....

時間顯示: 5:08....(晶片時間：05:06:18)

PS: 這次全馬第一次吃到西瓜..小蕃茄..手工饅頭....以往都是看人家收攤啊!!

[iOS] Class 1: NSArray, NSMutableArray, NSDictionary, NSMutableDictionary

NSArray

1. Can contain different variable types.

2. Contents of array cannot be modified. (add, remove and sort)

Create NSArray

NSArray *bookList = [NSArray arrayWithObjects: @"iPhone4", @"iOS", @"MacX", nil];

Add an empty object

[NSNull null]

Retrieve NSArray

NSArray *bookList = [NSArray arrayWithObjects:@"Moby", @"Frank", @"Tom", nil];
for (int y=0; y < bookList.count, y++) {
    NSLog (@"Book Title is %@", [bookList objectAtIndex:y])
}
result:
Book Title is Moby
Book Title is Frank
Book Title is Tom

NSMutableArray
1. Similar to NSArray.
2. Contents of array can be modified. (add, remove and sort)

Create NSMutableArray
NSMutableArray *bookList = [NSArray arrayWithObjects:@"iPhone4", @"iOS", @"MacX", nil];

Add an object (append to the end of the bookList)
[bookList addObject:@"New book"];

Insert an object at an specific place "index".
[bookList insertObject:@"New book" atIndex:index];

Remove an object at "index".
[bookList removeObject:index];

Sort Array: in alphabetical order
[bookList sortUsingSelector:@selector(caseInsensitiveCompare:)];


NSDictionary

1. Cannot be modified. (add, remove and sort)

Create NSDictionary
NSDictionary *book = [NSDictionary dictionaryWithObjectsAndKeys:
                                      @"a", @"1",
                                      @"b", @"2",
                                      @"c", @"3",
                                      @"d", @"4",
                                      @"e", @"5",
                                       nil];

Retrieve Object
[book objectForKey: @"1"];

NSMutableDictionary
1. Can be modified. (add, remove and sort)

Create NSMutableDictionary
NSMutableDictionary *book = [NSDictionary dictionaryWithObjectsAndKeys:
                                                  @"a", @"1",
                                                  @"b", @"2",
                                                  @"c", @"3",
                                                  @"d", @"4",
                                                  @"e", @"5",
                                                   nil];

Add an object
[book setObject: @"Value" forKey: @"KeyIndex"];

[LVM] Resolve to mount duplicate LVM

I built a new Linux system(Fedora10) in newH.D.(/dev/sda) and wanted to mount the oldH.D.(/dev/sdb) into it. But the oldH.D. has been installed the Linux system(also Fedora 10) before. Therefore, both newH.D. and oldH.D. has the same LVM group, "VolGroup00".
I'm trying to mount the oldH.D. and finally success.

1. Check the volume group.
[root@vincent local]# pvs
  PV         VG         Fmt  Attr PSize   PFree
  /dev/sda2  VolGroup00 lvm2 a-   465.56G 32.00M (newH.D.)
  /dev/sdb2  VolGroup00 lvm2 a-   931.31G 32.00M (oldH.D.)

2. Get the VG UUID of /dev/sdb2.

[root@vincent local]# vgdisplay
  --- Volume group ---
  VG Name                VolGroup00
  System ID
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  4
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                2
  Open LV               1
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               931.31 GB
  PE Size               32.00 MB
  Total PE              29802
  Alloc PE / Size       29801 / 931.28 GB
  Free  PE / Size       1 / 32.00 MB
  VG UUID               CQVzV7-xVVy-Om3Y-P2Ng-67d5-juHK-vTTj5a
  --- Volume group ---

  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               465.56 GB
  PE Size               32.00 MB
  Total PE              14898
  Alloc PE / Size       14897 / 465.53 GB
  Free  PE / Size       1 / 32.00 MB
  VG UUID               65loFF-2Tee-K4Wa-uUFf-oMRD-E1EH-iCKsQg

The VG UUID of /dev/sdb2 is CQVzV7-xVVy-Om3Y-P2Ng-67d5-juHK-vTTj5a.

3. Change the VG group name of /dev/sdb2.

[root@vincent local]# vgrename CQVzV7-xVVy-Om3Y-P2Ng-67d5-juHK-vTTj5a VG1T
4. Reboot the system. You will see the LVM group of /dev/sdb2 is changed to VG1T.

[root@vincent local]# pvs
  PV         VG         Fmt  Attr PSize   PFree
  /dev/sda2  VolGroup00 lvm2 a-   465.56G 32.00M
  /dev/sdb2  VG1T       lvm2 a-   931.31G 32.00M
5. Mount the /dev/sdb2 into our new system.

[root@vincent local]# mkdir /mnt/oldHD
[root@vincent local]# mount /dev/VG1T/LogVol00 /mnt/oldHD
