The correct way to send code to micropython via uart and run
2025-01-28 20:55:31
There are two mode in micropython: REPL vs paste mode. I guess the uart of my ESP32 board has no flow control, so you can't send all bytes at once, because it is too fast, so I sleep 100 ms for every 100 bytes. REPL mode You can't just send your python code, you need […]

香港嘅教育展，其實係教育玩具展
2024-12-13 16:46:42
香港花太多時間係用玩具去吸引學生學編程，但無提升到對編程概念嘅表達，其實所有人都應該明白，如果係鐘意寫Program嘅小朋友，絕大部份第一次接觸就會愛上，其實係唔存在你要買好多玩具俾佢試先會所謂「啓發」到佢地嘅興趣。而個社會咁做不外乎得以下幾種可能 上面三個原因互為影響互相加強，所以教育展變教育玩具展。 對香港嘅影響： 大家都係做代理唔研發，而大粒佬係呢啲展到都係得講野兩個字亦都唔會研發，最終後果就係香港洗好多錢係教育到最尾得個殼，香港人可以話俾外國人知香港投資左好多錢落教育，買左好多光鮮嘅玩具，除此之外乜都無。香港唔洗諗會出到Basic之父或者Logo之父等等一系列用實際行動去壓低學習難度嘅教育家，香港人唔洗諗，所以我地要以行動作出改變。 教育展中嘅清泉： 呢間公司做到好Deep，成套教學工具自己出，老細寫左本ROS嘅書有自己嘅學習思想，相信佢係用自己學習ROS嘅學習經驗濃縮出黎

香港編程界必須「代碼脫亞入歐, 工作脫港入陸」
2024-10-27 23:57:44
「代碼脫亞入歐」這一概念可以從幾個方面來理解，特別是在香港的編程界與日本的明治維新之間進行比較。 1. 歷史背景 2. 技術與創新 3. 教育與培訓 4. 政策支持 5. 文化與思維轉變 總結來說，「代碼脫亞入歐」不僅是技術上的轉型，更是一種思維方式和文化的變革。香港的編程界若能學習日本明治維新的經驗，將能在全球化的浪潮中更好地立足與發展。

香港神奇的Python仔現象
2025-01-28 02:28:01
香港有人係咁，廿幾歲畢業出黎做野，做左幾年對隻language開始熟，佢地唔係鑽落去language下面睇下發生緊乜野，例如啲code點compile呀，debug點做呀咁。佢地會作一出個難以解釋嘅現象，就係跳去另一隻high level language到再玩過，而當佢地玩到興起玩左幾年，佢地再次唔係想知道隻language嘅底層，而係再一次又跳去其它high level language到碌多一次，難道唔想知揸係手裏面把刀係咩黎？我叫呢一種現象做「香港Python仔現象」。舉個例子，2003年班友玩vc++，跟住跳去c#，跟住又跳去java，而家又跳去python。因為咁樣跳法本質上對過去學嘅語言都唔方認識得深，所以如果而家有個阿叔好推崇python，對其它language只停留係誇誇其談攞唔出到戰鬥力，佢大概率係咁。 要改變，就要做好科普，揭露python底層所有野，咁先至有機會改變。但呢班友會唔會變未知。
貴族 vs 老土 (貴族之女，第一個程序員Ada Lovelace)
2025-01-07 16:21:17
香港人嘅老土活該沒有科技，我而家分析俾你地睇香港人嘅老土係有幾老土，以及老土嘅香港人點解覺得自己唔老土 第一老土 ： 你憑咩 佢地所謂嘅論證不外乎係黎自你所受嘅教育同埋經驗，佢地會話你又唔係哈佛MIT學咩野人搞之類嘅言論，但呢班無讀歷史嘅人唔知好多科學家都係自學為主。（見下圖） 香港人老土在永遠人地努力做，佢地就會問"你憑咩"，其實呢一句好無敵，因為當你做緊而又未做完嘅時間你的確無力反駁呢一句，由其是你係做緊一啲你自己都唔知做唔做到嘅野時，你更加無力反駁。但呢班友永遠唔明，科學嘅發現好多時就係意外發現，好多野唔做就唔唔知得唔得，而呢班咁嘅人最叻就係用呢句去質疑你，佢地嘅內心世界就係「嘩，你做呀，你有無諗過㗎」，跟住就會覺得自己好似好有經驗，好似真係以為自己曾經做過咁，知道你條路係唔通，其實個現實就係，呢班友根本無做過，而更深一層嘅就係，佢地連去嘗試嘅基本實力都無，佢地唔係連個for-loop都寫唔出就係技術只夠寫啲script仔，真係可憐。 第二老土 ： 話人畫餅 呢個世界唔係所有人都需要理想，而理想呢樣野個實現率必定為低。香港地當然多人畫餅，但係係唔係畫餅好容易分，得個噏字唔做咪就係畫餅囉，會做嘅又點會算係畫餅呢，但係呢班咁嘅人就最叻攻擊啲為理想而行動嘅人。佢地個底其實係數佬，內心世界非常現實，我估計佢地後生嘅時候都曾經有理想，但手料跟唔上人到中年完全無哂動手能力，思想上變得越黎越現實，腦裏面諗一百個可能性去否定執行嘅成功率，不停俾借口自己逃避執行以至完全喪失執行力，佢地係編程上嘅實力只能點評人地寫嘅program，而自己乜都寫唔到。 Ada係連電都未係好識運用嘅年代就話要令機器有計算能力，如果香港班友返去佢嗰個時代，呢班友就會話人畫餅。嗰個時代根本就係非常簡陋。當呢班友話人畫餅，佢地嘅內心有一種好充盈嘅感覺，佢地會覺得：「嘿嘿，我真係叻，無俾你利用到」。但係個現實係咩呢，就係呢班友手料根本連俾人利用嘅資格都無，同你講下理想只係發下噏瘋而矣，唔好諗得自己咁有料可以俾人利用。 第三老土：話做唔做或者揾借口唔繼續做 話做唔做嘅人主要會話你唔夠條件做，做緊又揾借口唔繼續做嘅人會話發現你原來唔夠料做，又或者話發現你身上有啲缺點而唔再同你合作做。總之無論係咩原因都好，結果就係唔做。我地睇返Ada Lovelace個Case，當佢話要做一部Thinking machine嘅時候，佢mentor Charles Babbage唔會因為佢太天馬行空而屈佢畫餅，想反地會動手一齊做。而Charles Babbage亦都唔會話Ada無足夠嘅錢同埋未讀過大學就話人無料而做做下唔做。

我估實相係咁 ： 時間係亂序執行
2024-10-20 01:08:53
1. 時間係亂序執行，否則佛教不能自圓其說。只要亂序執行講得通，佛教整套哲學體系就會自己渝合。而家佛教哲學有幾個不能接合嘅地方，第一就係講所有野係空，但又因緣生。第二就係佛教嘅神通如果係真，根本容唔落係自己套哲學體系裏面。就算講得最清楚嘅龍樹，都只不過係話當「果」出現時，「因」先會被確定。如果時間係線性，呢單野根本完全唔合理，但如果時間就亂序執行，咁就好正確。因為係呢一對事物「因」＋「果」佢地嘅時間當然係順序執行，但跳出左呢一對事物，佢地嘅時間線就唔係，所以係佢地時間線黎講果要出現左，因先可以成立。企左出去佢地嘅時間線，其實係果先出現，再到因。我再舉多個你地可以睇到嘅例子。int x; x=123. 呢兩句code，你地用verilator synthesis出logic gate，係呢兩句code嘅時間線上先有int x，先可以有x=123. 但其實係int x之前，係另一條時間線，x已經存在，所以果出現時，姐係int x出現時，佢個因x先被確立。乎合龍樹所講嘅野。古人因為科技所限，無法舉證。 2. 時間係唔係線性，而亂序執行唔會阻擋世情嘅出現。我地感受到時間係線性，因為只係我地要靠時間去圍持呢個身體同識。舉個實制例子，CPU係亂序執行，但被執行嘅program會以為自己嘅時間線係線性，但其實唔係。只係CPU唔會張下一句指令嘅執行結果話比上一句嘅指令知，最終令到program以為自己條時間線有如河流一樣線性。
