有時真係 be careful what you wish for 啲尖子讀醫，起碼畢業之後大機會留返喺香港貢獻社會 如果學啲網友咁講，讀咩 CS呀 AI呀 科研呀，你估佢哋畢業第一件事係做乜？ 係即刻買機票，去美國深造，然後過幾年喺啲 Google 呀 Meta 呀 OpenAI 呀嗰啲公司打工，然後同人呻「哎呀矽谷生活好貴呀幾廿萬美金年薪唔係好夠使呀~~」 到時佢哋對香港嘅直接貢獻，就係每年暑假返香港探親喺香港消費幾個星期 🤡 講真俾我話事嘅話，啲尖子都係讀醫好。 That said, 地球村吖嘛，可能香港人都唔係好介意交多啲稅去幫美國培養科技人才嘅⋯(利申：有份賣啲豬仔過去)

喺香港有咩係「搵到食」？ 呢個問題其實係幾有趣嘅 拆解咗條問題，個答案就好簡單 點解有人會覺得公務員「搵到食」？ 因為一般印像公務員「鐵飯碗」只要唔犯大錯庸庸碌碌就自動有糧出 點解有人會覺得有專業牌就「搵到食」？ 例如醫生咁，大家嘅想像係，無論個醫生幾黃幾綠，有個牌幫人9簽假紙都唔會餓死 所以「搵到食」講緊嘅係不論能力，純粹靠個身份就可以有穩定收入嘅工作，而唔係講緊「賺到好多錢」嘅工作。 事實上，喺香港，賺好多錢嘅工作多的是，做生意、炒樓、炒幣、呃阿婆錢、賭馬*、OF賣相⋯⋯ 最top嗰堆肯定搵得多過公務員先。但做呢啲嘢唔係 show 張專業證書出嚟就得，要有能力有技術有人脈。如果你只係想像到自己係一個廢柴，咁上述要靠能力搵錢嘅方法就行唔通。 但一個廢柴做公務員或揸住張專業證書就唔同喇！ ⋯ 所以淨係得公務員同專業牌先「搵到食」 * 按：賭馬係賺到錢嘅。有興趣可以查下「顧鳴高」

我可以做證，呢位 cxrjj 當年考試日日同我一齊打 netbig2，結果佢夠分(拔尖)讀醫 (但冇讀) 一般人可能未見過 (好似cxrjj呢類) 啲痴線友，唔知道「考試天份」上限嘅 buff 係有幾強，可以令個冇乜點讀書嘅人隨便走去考都 5**/A..... That said, 「隨便考」同「為咗讀醫所以努力溫書」始終係有少少差別嘅。科科都 5** 嗰啲通常係有認真溫過書，而有一科半科考得差少少嘅有可能係隨便考⋯

話說十幾廿年前 香港大部份人都唔識打廣東話㗎 而家講返出嚟真係好好笑 唔知啲00後係咪會唔信 (例證1：連個「啲」字應該點寫都拗咗幾個月..... 呢個係 ~2014 年發生嘅 [呢單嘢我哋贏到開巷，衰在唔寫得落個CV度，真係要得閒拎出嚟自high] ``` 究竟啲人點樣頂得順用書面語溝通 或者加埋啲懶得意嘅台妹～諧音字 明明大家都係香港人😅好心打返廣東話 ```

好多時啲人睇統計數字 咩Band 1a入大學機率、畢業生平均收入之類 會以為只要自己都係嗰堆人入面 擲粒骰就會有個「隨機」嘅結果 可以計算到自己某啲所謂「機會率」 但其實呢個世界唔係咁樣運作 例如一班人100人有99個識唱歌 唔代表你喺嗰班度就會有「99%機會」識唱歌 你自己識唔識唱歌你自己好清楚 個所謂「99%」其實只係其他人喺冇任何其他資訊嘅情況下隨便寫返低啲不確定性 睇住其他人嘅平均值或普遍情況去估算自己會點 個前提係你自己個狀況同嗰班人真係相似 至於係定唔係，其實得你自己先知

Just a thought. I've always assumed a priori that the meta-context, world-that-host-simulations, etc. is practically infinite. What if it's not? That would be very interesting. The first question is whether there are practical implications between worlds that are "really" infinite, "only subjectively-infinite in some sense", and "definitely finite but large enough to not be practically exhaustible by mere mortal humans"... It's like, we now know that BusyBeaver(5) is 47176870, but is BusyBeaver(6) really a number we mere mortals can reason about? And if so, what does it mean to us that separates it from infinity? Not that I really doubt the true nature of all things is (subjectively) infinite. But while the nature of all things is the ultimate source, there may be intermediate structures that are in the range of "finite" BusyBeaver numbers -- finite in concept, but too large for us to understand for the time being.

Subsequently, present your content. Use one or more line breaks to separate instructions, examples, questions, context, and input data. 9 Incorporate the following phrases: “Your task is” and “You MUST”. 10 Incorporate the following phrases: “You will be penalized”. 11 use the phrase ”Answer a question given in a natural, human-like manner” in your prompts. 12 Use leading words like writing “think step by step”. 13 Add to your prompt the following phrase “Ensure that your answer is unbiased and does not rely on stereotypes”. 14 Allow the model to elicit precise details and requirements from you by asking you questions until he has enough information to provide the needed output (for example, “From now on, I would like you to ask me questions to…”). 15 To inquire about a specific topic or idea or any information and you want to test your understanding, you can use the following phrase: “Teach me the [Any theorem/topic/rule name] and include a test at the end, but don’t give me the answers and then tell me if I got the answer right when I respond”. 16 Assign a role to the large language models. 17 Use Delimiters. 18 Repeat a specific word or phrase multiple times within a prompt. 19 Combine Chain-of-thought (CoT) with few-Shot prompts. 20 Use output primers, which involve concluding your prompt with the beginning of the desired output. Utilize output primers by ending your prompt with the start of the anticipated response. 21 To write an essay /text /paragraph /article or any type of text that should be detailed: “Write a detailed [essay/text /paragraph] for me on [topic] in detail by adding all the information necessary”. 22 To correct/change specific text without changing its style: “Try to revise every paragraph sent by users. You should only improve the user’s grammar and vocabulary and make sure it sounds natural. You should not change the writing style, such as making a formal paragraph casual”. 23 When you have a complex coding prompt that may be in different files: “From now and on whenever you generate code that spans more than one file, generate a [programming language ] script that can be run to automatically create the specified files or make changes to existing files to insert the generated code. [your question]”. 24 When you want to initiate or continue a text using specific words, phrases, or sentences, utilize the following prompt: o I’m providing you with the beginning [song lyrics/story/paragraph/essay…]: [Insert lyrics/words/sentence]’. Finish it based on the words provided. Keep the flow consistent. 25 Clearly state the requirements that the model must follow in order to produce content, in the form of the keywords, regulations, hint, or instructions 26 To write any text, such as an essay or paragraph, that is intended to be similar to a provided sample, include the following instructions: o Please use the same language based on the provided paragraph[/title/text /essay/answer].

Interesting. I mean, the Jews have a history of describing things that sound like nuclear weapons like the Ark.... https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1475-4754.1967.tb00623.x RADIOACTIVJTY OF JERICHO BONES BY I. M. B,LAKE* and J. CYNTHIA WEBERt+ ‘Balliol College, Oxford University. 7 Research Laboratory for Archaeology and the History of Art, Oxford University. Research into the hydrology of springs at the Dead Sea shore (west bank) south of Qumran has revealed that some are radioactive. The radioactivity is peculiarly localised and not necessarily permanent, the onset of such contamination being unpredictable (Moyle and Thomas). That the spring Ain es-Sultan (site of ancient Jericho) is also in the Jordan Valley and may draw water from the same basic source suggests that, although it is clean today, it may in the past have suffered similar contamination. Archaeologically Jericho has seen two major periods of desertion. The first followed the “Pre-Pottery Neolithic B” period (Kenyon, personal communication). The second began about 1325 B.C. and lasted until after 800 B.C. (Kenyon 1965, p. 21 1). This latter desertion is Biblically attested and attributed to a curse laid by Joshua on Jericho (Joshua, 6. v/26). Subsequent reoccupation is recorded in connection with the “miracle” whereby Elisha is popularly supposed to have healed the water with salt (Kings 11, 2,v/ 19-22). Hebrew phraseology, particularly that of the passage often translated as “the water is naught, and the land miscarryeth” (Kings 11, 2v 19) offers a clear suggestion that the effect of the curse was a form of sterility. It has been argued that radioactive contamination of the spring would explain the observed effect recorded in the Old Testament (Blake 1967). The alpha radioactivity of 20 animal bones from Jericho has been measured. ‘Two of the samples are from the end of the Middle Bronze age (prior to the second desertion) the rest being Pre-Pottery Neolithic (PPN). The bones were crushed and the alpha radioactivity measured using a thick sample on a 2” diameter ZnS screen observed by a photomultiplier tube. Seventeen of the samples ranged in activity from 3.2 to 9.5 counts per kilosecond. The most recent of the PPN B bones was 15.3 cts/ks and the two MI3 bones were 24.3 and 31.7 cts/ks. The alpha ray energy spectrum was kindly measured for two of these samples by Dr. R. D. Cherry and Mr. Julian Hobbs of the University of Capetown. For a 3.6 cts/ks sample they found apparently the conventional Uranium series, whereas the radioactivity of the 31.7 cts/ks sample was composed almost entirely of 5.24k 0.06 MeV alphas, probably from 210Po supported by its parent zlnPb. If it is Z1oPb, which has a half life of only twenty-two years, the radioactivity measured at present cannot be the remnant of radioactivity acquired several thousand years ago. but must instead be contamination from more recent times. The data may thus indicate the presence of high radioactivity in the ground water at Jericho within the last few hundred years. Measurements on more bones from the area are planned. It is hoped to confirm the presence of 210Po and zloPb. and to determine the nature of the higher radioactivity in the most recent PPN (B) bone. Skeletal material from Jericho was made available through the good offices of Miss K. M. Kenyon. C.B.E., Litt.D.. F.S.A., Principal of St. Hugh’s College, Oxford.
