漫天一白漢江秋，
憔悴黃花總帶愁；
吉曜半升箕斗隱，
金烏起滅海山頭。

巳蛇︰《》文說︰巳，巳也。四月，陽气巳出，陰气巳藏，萬物見，成文章，故巳為蛇，象形。凡巳之屬皆从巳。

《淮南子‧天文》講︰巳則生已定也。或存巳之古意，新生兒。

蛇，它或从虫。

若講形質已具，氣息已出，因此萬物見，成文章，自然有理。但說『故巳為蛇』從何得出？據聞蛇的古字是它，當真是以『象形』形像為故，實在有點牽強。如今夏日正炎炎，何不就尋棵湯谷扶桑，

大樹底下好乘涼

，作此《大哉問》？？

夏娃的蘋果

金蘋果事件

牛頓的蘋果

圖靈的蘋果

根據《聖經‧創世記》記載︰

亞當和夏娃二人住在伊甸園中，後來夏娃受『蛇』的哄誘，偷食了『知善惡樹』所結的『禁果』，也讓亞當食用，二人遂被上帝逐出伊甸園。

□︰禁果是蘋果嗎？
○︰莫宰羊！
□︰那蘋果是禁果嗎？
○︰煩惱即菩提！！

也許希臘神話中關鍵之因緣生法的一顆『金蘋果』── 獻給最美女神 ──，引發 → 帕里斯的評判，導致 → 特洛伊戰爭。明示了『蘋果』與『誘惑』的關係，至於說怎麼聯繫上了『知識』，那只能問『牛頓』的了？

雖說『牛頓』並沒有創造『機械的宇宙』，如果仔細考察『運動定律』，假使再加上『物質組構』的『構造方程式』與『初始條件』── 位置和動量 ──，那麼該物之『運動軌跡』就被『確定』了。這演示了一種『軟體設計』之方法學，它以『資料驅動』為中心。或許艾倫‧圖靈非常了解那個『抽象機械』，所以創想發明了『萬有圖靈機』。只不過人類的知識還很難駕馭那樣的『仙女計算機』，然而隨著一九六零年代以來『硬體描述語言』 HDL hardware description language 的發展，也許我們終將受邀進入『計算機械的世界 』，一探『軟硬體的真諦』！『圖靈的蘋果』正述說著『尊重』與『寬容』，如今想來他早已『知道』這些『演算法』了的吧！！

派︰連假。無課。今日已夏至，窗明時尚早，天光逐日短，讀書趁年少。心懸廟會去是不去？但思學期雖已近尾聲，即將臨專題，講義還欠文章。就吟首

和夢得夏至憶蘇州呈盧賓客‧白居易

憶在蘇州日，常諳夏至筵。

粽香筒竹嫩，炙脆子鵝鮮。

水國多台榭，無風尚管弦。

每家皆有酒，無處不過船。

交印君相次，寒帷我在前。

此鄉俱老矣，東望共依然。

洛下麥秋月，江南梅雨天。

齊雲樓上事，已上十三年。

，權當已經如理而去，夢中也能行禮如儀。

What is LIRC ?

LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls.

Recent linux kernels make it possible to use some IR remote controls as regular input devices. In some cases this makes LIRC redundant. However, LIRC offers more flexibility and functionality and is still the right tool in a lot of scenarios.

Former versions focussed on home-brew hardware connected to the serial or parallel port. Descriptions how to build this hardware can be found here. Current versions of LIRC also support a variety of other hardware. An up-to-date list of all supported devices and the status of the according drivers is available on the left.

The most important part of LIRC is the lircd daemon that will decode IR signals received by the device drivers and provide the information on a socket. It will also accept commands for IR signals to be sent if the hardware supports this. The second daemon program called lircmd will connect to lircd and translate the decoded IR signals to mouse movements. You can e.g. configure X to use your remote control as an input device.

The user space applications will allow you to control your computer with your remote control. You can send X events to applications, start programs and much more on just one button press. The possible applications are obvious: Infra-red mouse, remote control for your TV tuner card or CD-ROM, shutdown by remote, program your VCR and/or satellite tuner with your computer, etc. I’ve heard that using lirc on Raspberry Pie is quite popular these days.

Supported remote controls

There are some config files for remote controls at the remotes database. This is about 2000 devices and counting. These devices should work with the general drivers or (if it lacks timing info) the driver used to create them.

If you can’t find your remote control here it does not mean that your remote control is not supported. It’s just that there is no config file for it yet. All remote controls that are supported by learning remote controls, i.e. almost any, should also work with LIRC.

Supported capture devices

Besides a remote control you also need a capture device to read the data from the remote. LIRC supports a broad range of input devices. As a starter, you can use the kernel built-in support for many USB dongles and similar. Besides this LIRC supports basically any conceivable way to capture your data including serial devices, parallel ports, sound input etc. You can see the complete list in the left pane.
