[笑話轉貼] 放Ａ片的資料夾該叫什麼好呢?
前天和同學們在咖啡館喝咖啡聊是非，討論到家中弟妹都資源共享，但是某些隱私性的資料該怎麼處理呢？
在唸中X大學碩士班的天才同學"小仁"，推了推他的千度眼鏡很老沉的說 "A片就A片，假什麼？"
大家都不爽他的傲慢態度，便問"要不你怎麼不被發現電腦裡的A片？"
只見他拿出他半年前買的NB(筆記型電腦)，開起電源，點取他的D 槽，裡面是論文報告夾、MUSIC夾、LETTER夾、DATA夾、哩哩扣扣一大堆資料夾。
靠！偽裝這招也太遜了吧？小仁一臉不屑的說"我有需要那種偽裝的地步嗎？"
看著他點了滑鼠兩下"趴"一聲：
一本道之XXXX、無碼之草X牛奶等，一大推A片檔名歷歷在目。
回頭再看他的資料夾，小仁放Ａ片的資料夾名稱是取啥？

“搖桿驅動程式”
當場把香草拿鐵噴到他的 14.1 吋螢幕上……。
後續-----
「搖桿驅動程式」再點進去還有兩個資料夾~~
一個叫「騎兵」~
一個叫「步兵」~
啥意思??
騎兵 = 有馬(碼)
步兵 = 無馬(碼)

Framebuffer:
MergeFB:
Merged Framebuffer mode allows you to use 3D acceleration on both heads of a dualheaded Radeon card. This is accomplished by creating a single large framebuffer with two viewports (CRTCs) looking into it. The current Radeon dualhead code creates two separate screens with separate framebuffers. they can be combined into a single logical screen using xinerama or used separately as separate X servers (host:0.0 and host:0.1). Merged Framebuffer mode can only be used to create a single logical screen. This is because a single framebuffer is shared between the two CRTCs. This is also the reason that HW accelerated 3D works on both heads. (freedesktop wiki)
also:
MergedFB mode is a special kind of Xinerama mode; it practically works like Xinerama, ie the two heads form a large screen which is transparent for applications. But this mode goes beyond Xinerama by even faking one screen to the X server itself. This provides the main advantage, namely that it is faster than Xinerama.-- www.winischhofer.net
also:
MergeFB is an XFree86 driver feature for video cards that have multiple heads. It is similar to Xinerama in that it also creates one big virtual desktop out of multiple screens.
The difference is in the implementation: Xinerama creates multiple screens with multiple framebuffers and MergedFB, like the name says, creates one big framebuffer with multiple 'viewports'. The main advantage of this method, is that it supports hardware 3D acceleration on all heads and it's generally faster. This is similar to 'TwinView' used in the nVidia drivers and the 'Big Desktop' in the ATI drivers.
Currently, this isn't supported in the drivers that come with the latest stable XFree86 release. Only in the MGA drivers from Matrox[1] and the experimental open source drivers for the SiS[2] and ATI Radeon[3] cards.

Framebuffer:
A framebuffer is a block of memory that holds one frame (one whole display or picture) of pixel data.
In the Linux kernel, there is a framebuffer device available. This device provides a hardware independent API for graphics devices. Applications see a framebuffer and can manipulate it though this API. It is accessed through a special device, normally
The main application of this in the Linux kernel is allowing the Tux logo at boot and a high resolution text console (a "Framebuffer console" -- the module for this is called fbcon). It's also for use on platforms which don't support a standard text mode. Other applications can also use it to get graphics without X or some other library, this is especially interesting for embedded devices.

/dev/fb* (e.g. /dev/fb0). It behaves much like other memory devices in linux, in that you can also read and write it with normal tools. For example copying the framebuffer to a file (effectively making a raw screenshot) can be done with:
cat /dev/fb0 > somefile
