香港啲阿叔，普遍都係kai嘅
呢篇文章係俾CS/EE嘅學生睇，目的係為左佢地唔好被香港啲阿叔摧毀左佢地做科技嘅熱情。係個社會上有班阿叔，年紀四五六十歲，個title掛到好大，又director又乜又柒咁，其實佢地嘅本質係kai嘅。 呢幾年我自己出錢資助左條team搞cpu，每年都會見到不同嘅阿叔，佢地嘅行為令我要寫呢篇文告誡班後生仔同呢班友相處要小心啲，小心自己做科技嘅熱情被呢班阿叔摧毀左。呢班友年紀係你地兩三倍，工作經驗可能係你地N部，就好似係山腳嗰度望咩山都高，所以你地要小心唔好佢地講乜你都信，呢個係好危險的。 啲阿叔根本就無實際經驗，一味鳩吹 做一個project你有技術問題，你可以試下問呢班阿叔，目啲係為左玩下佢地，佢地百分之九十幾係唔會答到你問嘅問題，當佢地答唔到就會講自己以前工作做過哂，不過呢啲low end野無做好耐，所以而家當可憐你指個方向你啦，你自己試下。你老味實情就係唔！撚！識！所有讀CS/EE嘅同學唔好被佢地fake到，技術呢會事好似踩單車咁，你幾年無踩跳上架單車到都會踩到，唔存在對個軟件一啲實際操作都唔識但又做過幾年呢回事。所以所有同學唔好因為啲阿叔鳩指你一個方向就以為佢識，唔好仲要以為佢地真係好有經驗。 唔係非technical就代表係其它非technical嘅方面都好勁好有經驗 啲做左管理好多年又或者做左好耐director嘅人唔代表好熟悉個market，相反地佢地絕大多數都係對個market無認識。啲學生搞startup班阿叔係技術上無法作出指導，佢地就會鳩指班學生要點做marketing，點到分析個business plan，講真，收！撚！皮！啦！你地做學生以為啲阿叔係個行頭到做左幾十年，升左上管理層就自自然然對個market好熟，呢個諗法好make sense但真係kai都無人有。如果你地班後生仔搞啲新野佢地聽幾句就知盤生意點搞，佢地發哂㗎啦，洗同你係到吹水咩。舉個solid嘅例子，香港好多sales director其實唔識sell野，更加唔熟market，否則佢地做左老細好耐啦。你地會有懷疑咁點解佢地會升到做sales director，咪因為佢地識屌sales仔囉，根本同熟唔熟個market一啲關係都無。佢地入間公司唔係間公司第一日成立就入去，係間公司成立左好耐，有哂既定業務先入，佢地照run㗎炸。唔好再信班阿叔講野啦。 大部份嘅阿叔都係虎頭蛇尾 人地蘇姿丰做半導體做左幾十年講野梗係要聽啦，香港啲阿叔做下呢樣人十口心下嗰樣，你地學生以為年紀大啲講野唔多唔少都要聽下，其實呢班友根本都無一件事做得深入。你地啲學生唔好佢地講乜都信。一個CS畢業嘅阿叔如果0code其實都可以收線，唔好被啲阿叔迷惑左以為佢地好專業係一件事到，佢地絕大部份都唔係，如果佢地係就唔係連你地啲學生問題都無法俾一個solid嘅回應。
點解香港人搞open source project唔掂嘅原因
好認真咁搞左五年open source project，認真程度係出錢又出力，而家總結點解香港人搞open source唔掂，又或者好難掂嘅原因 香港人動手能力極其低下 其實呢一點都唔洗啲咩證明同解釋，香港IT界人技術人仕其本上打份牛工或者為生活做下freelance仲有少少力之外根本就乜力都無。無力嘅原因我唔知，但係估計離唔開根本唔鐘意寫program呢回事。嗰啲阿叔話就有二十年經驗，其實減去為左份糧而工作嘅經驗基本上一年經驗都無。佢地嘅技術主要黎自份牛工嘅隨學隨做，佢地會好自豪咁講「嗰嗰都係咁㗎啦」，佢哋嘅世界自由香港牛工市場，牛場就係佢地生日嘅全部。外個嘅open source developer夢想改變世界嘅時候佢地會用所謂嘅廿年經驗去點頭評足，好似可批判到單咁，好撚猥瑣 香港根本無前輩可以照耀後來者 都唔好話提點下你，以我經驗香港啲阿叔有超過50%會叫你不如唔好搞，原因嘅白痴程度突破天際 : 學界基本上係搞笑 香港學界係唔會復Email，唔好旨意你有技術問題可以問大學，一定唔會復你。香港大學教授嘅動手能力人盡皆知，就連香港嘅大學生都知自己教授唔會做實際野。係香港一個教授一年出12篇理文咁你估到佢地係到做緊乜野，香港學界唔可能堅負起作為一個城市嘅大腦嘅角色，可以咁講對普通市民，學界簡直係腦殘。 無政府支持 創新科技署無一個支援計劃係支持open source，佢地每一個支援計劃都要寫business proposal，佢地最想就係錢，直接拉高到香港GDP，你搞open source如果無即時market佢地係唔會支持你。同理科學園數碼港創科局都係一樣。因為政府零支持，加上滿腦子講商業價值，所以香港無前瞻性嘅民間科學研究，民間全面熄火。係政府嘅角度要做科學研究只會依賴大學同研究院，但兩者係開源嘅研究實力和貢獻都非常底下。 香港無籌款呢樣野 Apache group同GNU group有一大部份經費係黎自籌款而香港係無籌款呢單野，外國嘅企業用open source軟件，大嘅公司會捐錢資助個project，有好多會出埋人一齊改善個software，而香港嘅企業同政府係唔會咁做。香港班客佢地嘅屬性係西客，用都不特止仲要不停投訴，隻手同跛嘅無分別，唔會落手落腳去改良開源軟件，所以開唔開源對佢地黎講無分別。

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。
