今天早上被闹钟吵醒，想到今天是应该给 Fatten 去上课回答问题的日子。我昨天给 Fatten 发了消息说我是否可以不去，Fatten 也没回我，所以今天还是去一下吧。磨磨蹭蹭地过去之后，今天感觉课上气氛比较低沉。Fatten 一直在尝试问学生懂不懂，但是学生也没有什么回应。今天讲的是 Nested List，是一个比较难、初学者可能掌握不是很好的知识点。大家都不回答的话，也不知道都懂不懂，就很尴尬。下课之后，我也辅导了几个学生这方面的问题。今天结束得还挺快，大概 5 到 10 分钟就搞完了。

走的路上，Fatten 也问我，考试什么时候考？以前的投资，他们有没有什么进展？投资是没有进展了，他们也没有联系，合伙人也去搞别的项目了，所以目前就专注考试吧，考完试再说。我直接给他说了，我说我以后要不然不来课了，他说可以的。就把重心放在 Office Hour 和设计以后用的 Assignment 3 上。

去墨客轩吃了饭之后，回家呼呼大睡。真的感觉墨客轩有种魔力，它的饭特别能让人睡觉。在睡觉之前看到了林毅，他们在做春招，招一个懂大模型相关的、有自行开发能力的人。我觉得非常适合我，所以非常开心地给他投了简历。写了很长的文字说我怎么适合。这时候我自己做的网站和我的 Skip Lecture 项目，就正好能用上了。感觉真是，所有东西做了都不嫌多，一切都是留给有准备的人的。这个网站以后肯定还是会继续坚持下去并且丰富的。我也在 B 站上发了一个留言，说了我这两个项目。今天晚上再来查看的时候，还有一个更牛的人也在投这个岗位。我的评论实际上应该是排在第二个想投递的人。

下午去上了 579 的课，这次讲的是 Review。课前有一个外国人就在说，你这课设计得太不好了，各种安排也没安排好。老师也没说什么，就说，我们这个 Review 之后你就会对整个课程的内容更加明晰。Review 的内容讲得我也听得半懂不懂的。很神奇的是，我们都是从同一个网站打开的 Review 的 Slides，我的 Slides 是 2024 年的，而他们打开的是 2026 年的，导致我一直找不到 Slides 的位置和公式，很尴尬。手动改了网址才找到。

上课的下半部分是直接给了一些例题。感觉那些例题都还是偏简单，能做出来百分之六七十吧，也能拿一个比较好的分数了。毕竟这个占比才 25%，即使考得很差，这课也能过。

晚上回来，收到消息说明天冻雨，要停工停课。所以回来点了一个超市的外卖，买了一些吃的和蔬菜，明天在家里过。晚上玩了两局杀戮尖塔，这次终于打过了，能一下子打到第三层。就感觉很困很困，想提前睡了。

I was woken up by my alarm this morning, and remembered that today was supposed to be the day I go to Fatten’s class to answer questions. I’d messaged him yesterday asking if I could skip, but he never replied, so I figured I’d better show up. I dragged myself over eventually, and the classroom atmosphere felt pretty flat. Fatten kept trying to ask students if they understood, but nobody responded. Today’s topic was Nested Lists — a tricky concept that beginners often don’t fully grasp. With everyone staying silent, there was no way to tell who understood and who didn’t. Awkward. After class I helped a few students through the same questions. Things wrapped up pretty fast — about five to ten minutes and we were done.

On the way out, Fatten asked me when the exam was, and whether there had been any movement on the old investment. There’s been no movement at all — no contact from them, and the partners have moved on to other projects. So the plan is to focus on the exam for now and revisit everything else after. I told him directly that I probably wouldn’t come to class anymore, and he said that was fine. The plan is to shift my focus to Office Hours and designing the Assignment 3 materials for future use.

After lunch at Moke Xuan, I went home and crashed hard. There’s genuinely something about that place — the food there has a magical ability to put me to sleep. Before I passed out I saw that Lin Yi was doing spring recruitment, looking for someone with a background in large language models and independent development ability. That sounds exactly like me, so I happily sent in my resume. I wrote a long message explaining why I was a great fit. My personal website and my Skip Lecture project turned out to be exactly the right things to mention. It really feels like nothing you build ever goes to waste — everything is waiting for the person who prepared for it. I’ll definitely keep building and expanding this site going forward. I also left a comment on Bilibili mentioning both projects. When I checked back tonight, there was already someone even more impressive also applying for the same position. My comment was probably the second one from someone expressing interest.

In the afternoon I went to the 579 class, which was a Review session. Before class, a foreign student was complaining that the course was poorly designed and that the arrangements were a mess. The professor didn’t say much, just noted that after the Review everyone would have a clearer picture of the course content. As for me, I followed the Review lecture about halfway. The strange thing was that we were all opening the Review slides from the same website, but my version was from 2024 while theirs was from 2026. I kept losing track of where we were and couldn’t find the right formulas. Very embarrassing. I had to manually edit the URL to get to the right version.

The second half of class was example problems. They felt fairly manageable — I could probably work through sixty or seventy percent of them, which should be enough for a decent score. This section is only worth twenty-five percent anyway, so even a poor performance wouldn’t be enough to fail the course.

Coming home in the evening, I got a notification that tomorrow there will be freezing rain — work and classes are cancelled. So I ordered grocery delivery, picked up some food and vegetables, and settled in for a stay-at-home day tomorrow. Played two rounds of Slay the Spire at night and finally won one, making it all the way to the third floor. Feeling very sleepy now. Ready to call it early tonight.
