《夏日書懷寄道友》‧崔塗

達即匡邦退即耕，是非何足撓平生。
終期道向希夷得，未省心因寵辱驚。
峰轉暫無當戶影，雉飛時有隔林聲。
十年惟悟吟詩句，待得中原欲鑄兵。

白金秋︰古本《竹書紀年》載：武乙三十五年，周王季伐西落鬼戎，俘十二翟王。南蠻一詞始於周代，楚王自稱為『蠻夷』，講：我蠻夷也不與『中國』之號諡。狄夷是何人？不過居在北與東。嘆奈何！『千年爭戰五行中，萬載生剋從不歇。』，直到如今。

《》文說：夷，平也。从大，从弓。東方之人也。《》史傳︰后羿是東夷領袖。眼下『天失候，地變起，人心符欲』，已現西金『鑄兵』之象。《》阡陌網須慎防『盜安特』，過河越界。若說果無『駭黑』事，這時刻苦『叮嚀』所為何來！？更休提，都是網中人，哪來的東南西北，只怕是誰人心『中』有鬼耶！！

派︰還不如印證 λ 運算︰計物數《中》裡講的『讀寫碼』之『心法』比較有趣︰

【越調】天淨沙‧秋思
元 馬致遠

枯籐老樹昏鴉，
小橋流水人家，
古道西風瘦馬。
夕陽西下，
斷腸人在天涯。

繪畫、照片與書法是哪種比較『寫實』？哪個又較為『抽象』？《秋思》中用具象《『藤』、『樹』、『鴉』》，來虛寫『時光變化』之《『枯』、『老』、『昏』》；以實景《『橋』、『水』、『家』》，將串成『應歸之所』的《『小』、『流』、『人』》；終至於『道』得『古』、『風』是『西』、『馬』又怎能不『廋』？此刻也許只該是『夕陽西下』？？否則哪歸結的出『胡不歸去』之『斷腸人在天涯』！！

或許『失重』的『實物』漂浮於天之涯海之角，反而更顯得『虛幻』的了！！而『抽象』的『圖形』一旦擬似具體構物，或會因『沈重』終將失去『空靈』的嗎？？

在《啃一塊唄 K TCPIP！！下》一文中，我們談到『TCP/IP』規範堆疊的『層層包裹』，目的是為了方便寫程式的人，無須理會太多『具體詳細』的『實作』，這能減少程式的『複雜度』，也使得它容易『分層除錯』。也就是說計算機科學中一般所謂的『抽象化』Abstraction 是一種『程序』與『資料』的『封裝』方式，使用該程序或資料的人透過封裝之『應用界面』的『用法說明』來調用，不必知道『那裡頭是怎麼作的』。這麼說來這個『抽象的目的』反倒是為了『實用性』的了！！

Loopback

Loopback, or loop-back, refers to the routing of electronic signals, digital data streams, or flows of items back to their source without intentional processing or modification. This is primarily a means of testing the transmission or transportation infrastructure.

Many example applications exist. It may be a communication channel with only one communication endpoint. Any message transmitted by such a channel is immediately and only received by that same channel. In telecommunications, loopback devices perform transmission tests of access lines from the serving switching center, which usually does not require the assistance of personnel at the served terminal. Loop around is a method of testing between stations that are not necessarily adjacent, where in two lines are used, with the test being done at one station and the two lines are interconnected at the distant station. A patch cable may also function as loopback, when applied manually or automatically, remotely or locally, facilitating a loop-back test.

Where a system (such as a modem) involves round-trip analog-to-digital processing, a distinction is made between analog loopback, where the analog signal is looped back directly, and digital loopback, where the signal is processed in the digital domain before being re-converted to an analog signal and returned to the source.
