logic gate呢一層

我地平時用嘅variable,如果化到落logic gate呢一層,你無法找到佢嘅真身,佢亦都好可能同其它variable所化生嘅logic gate交織埋一齊,你亦都無可能找到佢確實嘅存在嘅時間,一切好虛無,但有其功用。呢個係coding體驗空性嘅其中一個睇法。而家啲programmer執著玩排位玩放位玩lang玩framework,真係好可憐。

一本由讀computer science嘅人所寫嘅哲學書

我而家總結一下書中所帶出的哲學問題,所有讀computer science嘅人都應該花時間思考一下: 神。人。機械人。三者之關係 機械人的超限作用 人好明顯就是當機械人係奴隸 機械人之自我認同,自我意識 克隆人是機械人? 人是機械人?

佛教中的鬼與香港人普遍認為的鬼是不同的

雜心論對鬼有比較祥細的描述:1. 鬼有六識:眼意鼻舌身意,中國人普遍認為鬼無肉身,所以無身識2. 六道中各有不同的鬼,人死變人鬼,畜牲死變畜牲鬼,最特別的就是地獄眾生死後變死獄的鬼,由此可見地獄道眾生不是鬼,而餓鬼的眾生也不是鬼,如果不是鬼又怎會死了才變鬼呢3. 鬼經過女性的陰道投胎,而不是飛入個肚到投胎4. 有兩種說法,人道的鬼只能見到人道的鬼,第二種說法是人道的鬼可以見到比人道更低層次(地獄/畜牲/餓鬼)的鬼5. 鬼有時是見不到其它的鬼的,而中國的鬼應該是一定見到其它鬼的6. 鬼入胎後近右手為男,近左手為女,中國的鬼無此說法7. 地獄道的鬼頭向下腳向上而行走,只有天道的鬼才會飛8. 六道中各道的鬼與其道眾生,身型大小相差不遠

JDK 11 problem

JDK11網上好多人都有我呢個問題,就係11 refactor左好多class,如果用嘅library係jdk8到compiler就會有呢個問題。Netbeans進度太慢,最新嘅netbeans 9.0只支持jdk10仲要好多plugin都用唔到,原因係netbeans.org呢個domain仲未貢獻俾apache基金會。所以原先netbeans plugin啲lib用緊package org.netbeans仲未可以移到俾apache,呢單野唔知搞幾耐。
