@dviolettchan @lidangzzz 他的建议对大部分人其实是对的，对于少部分会做solid work的学生，我觉得也不会听他的就放弃当下的路

Disappointingly, many misleading KOLs (like @lidangzzz 🤣) are claiming that math and physics aren't useful, which ends up steering junior students away from real, meaningful research. I would never encourage chasing hype before building a solid math foundation.

I’ve always believed that a good ML paper is essentially A + B: A is an impactful real‑world problem, and B is a classical mathematical tool that provides provable guarantees and intuition. If you know a lot of good Bs, your paper will naturally look novel and sound.

@KKaWSB 温哥华通高速了吧……很奇怪为什么不选择郊区租房子去住

为了省房租，这位加拿大籍学生选择乘飞机去留学。往返机票费用为150美元，他每周往返两次。他每月花费1200美元，而如果住在离留学中心同一个城市，房租则高达2100美元。

@PatrickSam72175 @jefflijun 漫游的话我个人经济条件有限，可能只能考虑那种美版携程上的便宜eSIM之类的价格，12刀一天我说实话舍不得……顺便问一下，这样的漫游网速如何？

@Joseph_OPT @jefflijun 漫游还是国际网络，没有影响，我这里十二一天，不限流量啊。

笑死了，还能再假一点吗？加拿大的孩子，你让他去个不能上油管不能用Google不能登录Instagram，他会觉得你这个老登有病吧。100个美加长大的孩子99个连跟着父母回国度假都觉得是负担

@jaycheninfo 看了一下CS240，是Programming in C，那就是学生的问题。本科C语言用AI完全没必要，用了以后学不到什么。AI写代码是很厉害，但是一个合格的programmer至少要有debug的能力。但凡这课是proof-based或者heavy-coding orient的，动不动几个projects，我都会觉得学生应该用AI

普渡大學電腦系最近有些騷動，CS240這門必修課，通常是幾百個人的大班，學期快結束的時候，教授Jefff Turkstra突然宣佈有近一半的學生涉嫌作弊，在作業上用AI。他用他自己開發出的系統偵測學生作弊，然後給學生兩條路，一是承認作弊，所有作業零分計算，二是不承認作弊，他直接把你當掉。這麼嚴格的舉措，讓普渡電腦系翻了過去，群情激憤下，系主任要在下週一與學生座談，討論解決方案。 這個事件有很多觀察的角度，我是不站在Turkstra這邊的。在AI的巨浪面前，要怎麼樣教電腦程式，甚至是還適不適合讓這麼多的學子，走這條路，有很多的看法，但最糟的看法就是反對到底，以學生應該會「基本功」為理由，全面反對AI的使用。這種古板的作法，違反新世代AI native的訓練方式，並不適合時代最前沿的學校教導學生，反而會讓學生在職場處於不利的情況。但這是所有電腦系都得面臨的抉擇，和這個普渡的單一事件，關連較小。 Turkstra的作法，有法律上的問題。如果他的抓弊系統，沒有百分之百的把握，他的指控站不住腳。現代法治國家的一個重要法理原則是指控者必需提出證據，被指控的涉嫌人，沒有自證清白的必要性。所以如果Turkstra不顧一切要硬幹到底，很可能會被告上法庭，而且會輸。而且不用上法庭，他的方式，可能在校規上，就失去著力點。 但Turkstra最大的問題是「不教而殺」。他有一整個學期，在學生初次「犯規」使用AI的情況下，提出警告，甚至立刻處罰，但他不這麼做。他累積到學期末，一次重錘下來，沒有任何教導學生使其反省的空間，擺明要對付學生，那就是孔子說的「虐」。我教書二十餘年，看過有些老師十分嚴格，嫉惡如仇，抓起作弊來毫不留情，在其它的規定上，也沒有讓學生犯錯的空間，說一就是一。但我總認為，為人師表，或是為人父母，多一點的包容，多一點的同理心，路可以走遠一點。人生有許多的不如意，甚至有許多不幸的意外，為了去懲罰少數作惡的人，而傷害了無心犯錯的學生，何苦呢？所以我的學生每一個人都拿A，XD。

@yhbkqs 这个话似曾相识

当逻辑自洽起来，就和主席想到一块了

Joseph Ratzinger was elected as pope on 19th April 2005 A day before his election, he delivered one of his most famous and prophetic speeches Coining the phrase 'Dictatorship of Relativism', he predicted how the West would see relativists imposing their will on those who had traditional beliefs It is a compelling and very powerful read, especially in light of recent events in the West: 'How many winds of doctrine have we known in recent decades, how many ideological currents, how many ways of thinking. The small boat of the thought of many Christians has often been tossed about by these waves - flung from one extreme to another: from Marxism to liberalism, even to libertinism; from collectivism to radical individualism; from atheism to a vague religious mysticism; from agnosticism to syncretism and so forth. Every day new sects spring up, and what St Paul says about human deception and the trickery that strives to entice people into error (cf. Eph 4: 14) comes true. Today, having a clear faith based on the Creed of the Church is often labeled as fundamentalism. Whereas relativism, that is, letting oneself be "tossed here and there, carried about by every wind of doctrine", seems the only attitude that can cope with modern times. We are building a dictatorship of relativism that does not recognize anything as definitive and whose ultimate goal consists solely of one's own ego and desires. We, however, have a different goal: the Son of God, the true man. He is the measure of true humanism. An "adult" faith is not a faith that follows the trends of fashion and the latest novelty; a mature adult faith is deeply rooted in friendship with Christ. It is this friendship that opens us up to all that is good and gives us a criterion by which to distinguish the true from the false, and deceit from truth. We must develop this adult faith; we must guide the flock of Christ to this faith. And it is this faith - only faith - that creates unity and is fulfilled in love. On this theme, St Paul offers us as a fundamental formula for Christian existence some beautiful words, in contrast to the continual vicissitudes of those who, like children, are tossed about by the waves: make truth in love. Truth and love coincide in Christ. To the extent that we draw close to Christ, in our own lives too, truth and love are blended. Love without truth would be blind; truth without love would be like "a clanging cymbal" (I Cor 13: 1). Let us now look at the Gospel, from whose riches I would like to draw only two small observations. The Lord addresses these wonderful words to us: "I no longer speak of you as slaves.... Instead, I call you friends" (Jn 15: 15). We so often feel, and it is true, that we are only useless servants (cf. Lk 17: 10). Yet, in spite of this, the Lord calls us friends, he makes us his friends, he gives us his friendship. The Lord gives friendship a dual definition. There are no secrets between friends: Christ tells us all that he hears from the Father; he gives us his full trust and with trust, also knowledge. He reveals his face and his heart to us. He shows us the tenderness he feels for us, his passionate love that goes even as far as the folly of the Cross. He entrusts himself to us, he gives us the power to speak in his name: "this is my body...", "I forgive you...". He entrusts his Body, the Church, to us'

Good morning 😅 ☕

@failcatcat BIC呗

为什么美利坚那么强大，水笔那么垃圾？？？？？？？？ 根本没法买到好用的笔和笔芯

@BingLiu34173809 Francis也慈眉善目，但是他真的适合当教宗吗……

我去年去梵蒂冈还是见过教宗的，挺慈眉善目的，特朗普已疯，鉴定完毕。

@taki8964 这是天主教学校，天主教学校不支持天主教教宗会引发大问题

最老保的名校都支持教宗

@Historybaoye 怪不得最近油价涨了……原来都出口了？

伊朗🇮🇷战争 生生的把我们德克萨斯 弄成了世界🌎石油最繁忙的中心！🤔

@8964rinrina8964 孩子是无辜的，为什么生下来就要被这样折磨，唉

进去看了一眼这个孩子才4岁🐒 家长在孩子4岁的时候才知道大号已废，殊不知孩子早在投胎的时候就知道这个号废了🤡

So true

简直是疯了，我不知道如何评价，但是我建议这位父亲应该去看看医生或者其他的什么人。

@syhily @skywind3000 那你为啥会觉得四岁的孩子能理解权利与义务？利益交换？

@lidangzzz 而且反过来说，TCS/algorithm/MLtheory方向多的是math/stat/ieor背景的学生，甚至某些细分领域几乎都是这些背景（纯CS的背景应该不超过1/5）。那这些方向，或者这些人在cs领域就有明显优势嘛？好像不一定吧。

@lidangzzz 我觉得这是个误区，不要和general cs students去比，要去和对应方向的学生去比。如果一个方向平均数学水平一般，那可能说明这个方向并不强依赖数学能力，数学好不代表“优势”。和TCS/algorithm/MLtheory这种数学高度依赖的方向去比，不同方向依赖的数学还不一样，那比的是专精+经验，那就不一定是优势了

我认真地咨询一下， 各位985数学物理系本科毕业的朋友们， 你们真的认为自己线代高数概率学得比同校比你们高考高几十分的计算机系的同学强整整一大截， 认为同校CS系本科同学数学基础全面被自己吊打， 所以你们数学物理比计算机系做大模型更有巨大优势，同校CS专业本科生跟你们比是纯种大垃圾吗？
