另外,找到的資料裡也提到
較新的網卡(通常指GbE)已經有把MDI-X實做在硬體上
所以會自動偵測Tx/Rx,不需要再特地使用跳線

Vim -- "swap" file and "backup" file

2011-08-24T18:53:00.000+08:00

使用Vim編輯時, 若不想讓它產生系統暫存檔 (swap file),
或是有更動後存檔時的備份檔 (backup file), 可用以下指令:

set nobackup
set nowritebackup
set noswapfile

但不建議如此做, 因為在發生不正常情況時就無法recover
如果只是為了讓工作目錄更乾淨, 可以更改swap file及backup file產生的目錄
指令如下

if has("win32")

set directory=c:\\tmp,c:\\temp

set backupdir=c:\\tmp,c:\\temp

elseif has("unix")

set directory=/tmp

set backupdir=/tmp

endif

以上指令都是寫在vimrc中即可

Vim的小技巧 (括號配對/消除^M/colorscheme)

2011-08-08T19:40:00.003+08:00

筆記一下一些可能會用到的小技巧...

1. 尋找配對的括號 => %

2. 消除 ^M 符號 => :%s/^M//g
(^M 要用 ctrl-v ctrl-m 打出來)
或是 :%s/\r//g

3. colorscheme => :colorscheme [scheme_name]

MRC

MRC => Memory Reference Code

找不太到說明的網頁,只有看到一小段

One of the most important aspects of the BIOS for an Intel board is the Memory Reference Code (MRC). 'The MRC is part of reference BIOS code, which relates to memory initialisation in the BIOS. It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited and compiled by board makers. It provides a space to develop advanced features, and the ability to tune memory. '
