Install Windows 8 consumer preview at virtualbox

Installed at w8 cp at VirtualBox in Ubuntu 11.10.
The default version of VirtualBox that came with 11.10 is version 4.1.2.
No Windows 8 option, so select others, system will up, and stop at recovery option.

Google found that 4.1.8+ version should already come with w8 option, update to 4.1.8, w8 up without problem.

Google Spreadsheet ,TEXT() 函數, format 的語法

在一個對網路很不友善的環境下....(略)...

沒想到最廣泛被大家使用的竟然是 Google Doc ... 想想也合理... 因為 Outlook 空間過小... 不適合丟大檔案... 公司的 server 空間使用規定很嚴... 一切都要靠 VPN ... 所以最後大家都把檔案都丟 google doc... 也正好利用了他天生方便共筆的特性... 同步大家的資訊也容易....

所以.. 除了漸漸淡忘的 Excel 語法後... 我又開始學習 Google spreadsheet 比較進階的用法了....

Build UEFI EDK2 UnixPkg 64bit under Ubuntu 11.10

Fellow the instruction here :
http://blog.xuite.net/meloscheng/note/56299386

Two place need to modify :

1. Link crt*.o to correct place :

root@neou11:/usr/lib# ls /usr/lib/crt* -l

lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crt1.o -> /usr/lib/x86_64-linux-gnu/crt1.o
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crti.o -> /usr/lib/x86_64-linux-gnu/crti.o
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crtn.o -> /usr/lib/x86_64-linux-gnu/crtn.o

2. Use GCC 4.6 instead of 4.4 :

neo@neou11:~/work/edk2-12898/UnixPkg$ svn diff build64.sh
Index: build64.sh

Then SecMain could be built, and running.

Don`t mess your environment, use schroot instead

以 Linux 當開發環境的人, 常在系統裡安裝一堆有的沒的 Library, 特別是要 match 某些 open source 的開發需求時, 有時候萬一一個不小心, 把你日常的桌面環境搞爆炸了, 復原或是重新安裝可就是一筆大工程...

在一個對網路不友善的環境中,  要是爆炸了, 那更是一種難受的折磨...

要是純是 x86 的開發需求, 可以用單純的 chroot 環境來應付, cross compiler 也有成熟的 sandbox mode 相關的工具,  另外 schroot 則是補足 chroot 的需求, 讓一般的用戶也可以切換到一個隔離的開發環境, 適合在多人分享的 build server 下使用...
