上週日(03/08/09)是童軍節,也是我家的小王子第一次穿上制服參加活動的日子 !

順便來張大合照吧 :

折衣服一直是我每個週末的固定工作,但總是發現原先衣櫃內辛苦排放整齊的衣服,沒幾天就被弄的亂七八糟,因此本週我決定推出 衣服收納 SOP (2.0) - 抽屜櫃版 來應戰,而此一 SOP 必須滿足下列 High level requirement :

• (H)必須將有限收納空間之使用效率發揮至極限
• (H)衣服收納後必須能一目了然,以利使用者挑選衣服
• (H)取用單一衣服後原有收納空間的整齊必須維持一致

一開始我們來看看未整理過的衣服及收納空間 :


首先我們先用 PP塑膠瓦楞版作一個長方形的板子 : 長度略小於抽屜櫃長度的 1/3 ,寬度略小於抽屜櫃的深度即可,因為我們必須考慮到布料經折疊後是有厚度的:



此外為了滿足其餘 requirement 我們必須製作如下圖所示的隔板 2 個,而為了固定隔板,我特意在頭尾加工了一下,而裁切必須 考慮PP塑膠瓦楞版本身的厚度,以及不要切到支撐面即可 :


東西組合後的樣子如下:


經過一番努力,此次我們總共塞進了 47 件衣服,結果令人相當滿意 :


PS.PP塑膠瓦楞版可以到 B&Q 買,如果我沒記錯一大張才 NT$60 多..

哇..連 "久立生公平" 的主題曲也有...

真是讓人驚豔的影片,真難想如此氣勢磅礡的音樂只需一台電子琴就可以搞定

昨天朋友跟我提了一個相當傳神的簽名檔 : "Licence to kill -9" , 相信管過 Server 的朋友應該都會有同感 , 聽說 米國 G 社 在招募 Linux system administration 時會考到各種 signal 的意義,看來我該找個時間來好好的 K 一下,相關的資料了

Enable Wireless LED on Ubuntu

This How To gets that Wireless LED working on my laptop (HP NC6230)

add led=1 in /etc/modprobe.d/options

VLan Trunk between D-LInk & Cisco switch

Due to reconstruction office network I has been google this kind of example for couple days , but didn't find any complete example so below is my success experience and topology



look like default VLan (VLan 1) cant's cross switch , so I redesign VLan list like below

• VLan 10 : OA Network
• VLan 123 : WLan for guest
• VLan 250 : ADSL for LAB

Config of switchs

Cisco switch

• Create VLan in :

server-switch#vlan database
server-switch(vlan)#vlan 10 name OA_VLan_10
server-switch(vlan)#vlan 123 name OA_WLan_123
server-switch(vlan)#vlan 250 name OA_ADSL_250

• Config of Switch :
  interface FastEthernet0/1 ==> assign to VLan 10
  switchport access vlan 10
  !
  interface FastEthernet0/2
  switchport access vlan 10
  .
  .
  interface FastEthernet0/9 ==> assign to VLan 250
  description Link to Office WLan
  switchport access vlan 250
  !
  interface FastEthernet0/10 ==> assign to VLan 123
  description Link to Office ADSL
  switchport access vlan 123
  .
  .
  interface FastEthernet0/22
  switchport access vlan 10
  !
  interface FastEthernet0/23

description Link to office 254 SW port F/E 0/23
port group 1
switchport trunk encapsulation dot1q
switchport mode trunk

• !
  interface FastEthernet0/24
  description Link to office 254 SW port F/E 0/24
  port group 1
  switchport trunk encapsulation dot1q
  switchport mode trunk
  !
  interface VLAN1
  no ip address
  ip directed-broadcast
  no ip route-cache
  shutdown
  !
  interface VLAN10
  ip address 192.168.0.253 255.255.255.0
  ip directed-broadcast
  no ip route-cache
  !

這是記憶中第四次簽手術同意書, 不同以往我這次很仔細的將文件上的條文一一看過,但事實上我一個字也沒看進腦子,我只希望下週五的切片檢查是 ok 的,並且再也不用簽這種文件了
