I didn’t get up too early this morning, but after dropping Hamer off at school, I came back home to continue reading and practicing English. Starting the morning quietly with a few pages of a book and some English audio tracks seems to fill me with energy for the day. After breakfast, I headed to work, and I could feel the extra boost from that bit of self-improvement earlier.

Today’s English practice followed the methods described in One Thousand Hours. I listened and read along, identifying several areas where I could improve. Compared to the more passive style of simply following along with Speak, this active, self-directed learning allows me to pinpoint my weaknesses, which feels much more rewarding.

At work, I had a few meetings during the day, and I spent the rest of my time discussing the implementation of new features, along with ways to display and save data. The biggest challenge was figuring out how to make the saved data play back in chronological order. Since many details are still undecided, the progress is slightly slower than I had hoped.

In the evening, I played badminton with colleagues. I just played for less than an hour, but worked up a sweat. On my way home, I got a call from Hamer, asking me to come back quickly. It was great timing to be heading home early today, not only because I promised her last night we’d play badminton together, but also because her teacher assigned quite a bit of homework. This way, we could play and still leave enough time for her to complete her assignments.

Hamer also received her winter school uniform today—a set of fleece-lined sportswear and a down vest. Now she has three uniforms, including her previous two sets.

Recently, I’ve also made some changes to my lunch habits, opting for a combination of meat and vegetables from the convenience store, cutting back on carbs. It’s a lighter meal, but I feel more physically and mentally refreshed.

Since I was up late finishing a few things last night and wanted to get to bed earlier today, I saved this journal entry for the following morning. Writing it in the morning actually gives me more time to reflect and keeps me from feeling guilty about staying up late.

Today was a fulfilling day. Not only did I complete my work tasks, but I also made some new attempts as planned and gained a lot of valuable knowledge.

In the morning, I woke up Hamer, saying, “We’re a bit late today; we need to hurry up, okay?” She got up, went through her morning routine—washing up, using the restroom, getting dressed—all in one smooth, efficient flow. She looked so grown-up, and I could really see her gradually maturing.

Xiaoyan had to head to the airport this morning for a three-day business trip. After wrapping up my tasks as planned, I focused on developing the GNSS functionality. My primary goal for the morning was to figure out how to create a new user experience. As I worked, some design ideas started to take shape in my mind. Just as I was about to delve deeper, PE mentioned that there might be some upcoming changes, so I decided to slow down a bit. I spent the afternoon experimenting with and refining the data structure to ensure it would meet the requirements.

At noon, I had originally planned to study some English shadowing techniques, so I picked up Li Xiaolai’s book, Everyone Can Use English. Before I knew it, I was absorbed in another of his works, One Thousand Hours, where a chapter on “self-training” made a strong impression on me. The author suggests that such self-directed learning experiences not only reshape personal learning habits but can even influence the destiny of an individual or an entire family. This really resonated with me, and I started reflecting on Hamer’s education and my own lack of thought in this area.

In the evening, when I got home, Hamer was playing at the plaza. I suggested, “How about we play some badminton?” Her eyes lit up, and she eagerly jumped at the idea. I was thrilled by her progress; we had some great rallies, and her serves have improved a lot. After badminton, we also did the Seven-Minute Workout. It was a bit tiring, but we both felt great afterward.

Before bedtime, I watched SpaceX’s fifth Starship test launch with Hamer. This time, they managed to successfully recover it. The moment the rocket rapidly descended and was gently caught by the “chopsticks” was breathtaking. Then, as Hamer lay in bed, I shared some of what I had read today about “self-training.” She quietly fell asleep while I was talking.

This morning, I got up early to get ready to go to Chaoyang Church. After getting up, Hamer suddenly changed her mind and decided she wanted to come along with me, so we set out a little later than planned. It was an overcast morning, and as I rode the electric scooter, the chilly wind hit me, seeping through my clothes—it was a bit cold. We even took a slight detour on the way. When we arrived at Chaoyang Church, the staff informed us that young children weren’t allowed inside, which was a bit disappointing. We wandered around the courtyard, took a look at a small exhibition inside, and then left.

Why aren’t children allowed inside? I suspect it might be to allow them to make their own decisions about religious beliefs when they grow up, or perhaps it’s because church services are solemn and quiet occasions, and lively children might disrupt the proceedings. Next time, I could just ask to find out the specific reason, rather than guessing.

Afterward, we headed to Sun Park to play. We parked the scooter at the north gate and walked south toward the amusement park area, where Hamer most wanted to go. I let her navigate us to the destination using the map on my phone. She seemed quite interested in the task and looked like she was getting the hang of directions. Along the way, we saw many interesting things, and she would often stop to fully enjoy them—feeding small animals, running around on the grass taking photos, and climbing on the equipment for exercise. Today, we went on the children’s roller coaster, parachute tower, flying chairs, magical journey, and the dream world ride. When we got to the last attraction, “Rapid Transformation,” Hamer decided to give it a try and loved it right away. One ride wasn’t enough; she immediately went for a second round. After a day of fun, we made our way back, heading to Solana to meet Xiaoyan for lunch.

There was a minor incident before dinner. I told Hamer to wash her hands, but she was too tired and didn’t want to. I got upset, wondering why she would come all the way to the entrance but refuse to go in and wash her hands. She retorted, saying she didn’t like the restaurant and didn’t want to eat there at all. In the end, she didn’t wash her hands, and I was quite frustrated. When we arrived at the restaurant, Xiaoyan comforted her and took her to a nearby restroom to wash up. Meanwhile, I stayed quiet and focused on eating, feeling in a bad mood. I worried that staying longer would dampen everyone’s spirits, so after finishing my meal, I decided to head home alone. I took a slow walk along the Liangma River, and halfway back, I got caught in a heavy rainstorm and took shelter under a bridge for a while. The walk wasn’t tiring, but I felt exhausted and low on energy. After getting home, it wasn’t long before they arrived too. I ended up taking a long nap until the evening, then tidied up some clothes, took Hamer out for a walk, and bought some yogurt and fruit. We had a light meal together.

Hopefully, I can get to bed early tonight and wake up early tomorrow.

早上哈妹6点就醒来，因为昨天玩得太累8点不到就睡了。我7点多起来，给她剪指甲，一个不小心，剪深了些，都留了点血。她疼，一直在说我，最后也是委屈的哭起来，并拒绝跟我说话，最后小眼送哈妹上学去。

上午做了点儿计划，白天工作主要是在新功能的探索上。

中午给哈妹买了点吃的和可爱的创可贴，晚上回来带给哈妹，她很高兴，也安慰我说她已经原谅我了，早上只是太疼所以生气。小眼看到我京东上买的可爱的创可贴，觉得很好笑，特意问我是不是要补偿哈妹。

晚上回来做点暑期游玩计划，然后接小眼，聊了聊借钱的事情，我比较担心和愧疚。

今天我的身体感觉好多了，整个人走起路来都轻松了很多。中午去做了个核磁共振，等明天再找大夫看看腰椎的具体情况。

上午解了个 bug，一不留神一个小时就过去了，下午主要是在继续优化 location tool。

今天看的两个 YouTube 视频印象特别深刻。第一个视频是 Adele 参加 Ellen Show 节目，她被叫去一个咖啡店。Ellen 远程让 Adele 说啥她就说啥、让她做啥她就做啥，Adele 全都照着做，一唱一和很有趣。第二个视频是 Eight Passengers 拍的，他们家里最小的孩子犯了错，妈妈和孩子是如何处理这件事情的。期间大女儿安慰妈妈，小女儿来认错，儿子也跟着问能不能打点零工等都让我觉得很温柔和好笑。

晚上和小眼、哈妹一起捣鼓领夹话筒和手持稳定器，哈妹完整的唱了小孩子大梦想。

今天晚上7点多些又开始想要下雨了，然后下了点儿。

晚上十一点，又开始起风、闪电、下雨，不过这次不大。

上午 retro 会议，下午上课，依旧是感觉高效的一天。上完课后把自己的日历更新了一下，大概能更好的去执行吧。

早上哈妹起来的很快，七点半时去喊了一下，她就起来了，上厕所、洗漱、穿衣…

晚上和哈妹玩了会儿手画手剪拼图，然后就是用新买的领夹麦克风来唱歌录音玩儿，乐此不疲。

晚上七点十分，去接哈妹，此时开始狂风大作，我们狂奔回家。为遮挡路上可能的断枝而撑着的伞已被吹的不成形，哈妹哈哈大笑。到家后，赶紧给小眼打电话，并拿着雨衣冲出去，此时已是大雨倾盆，所幸刚过红绿灯就看到了她，一起跑回家。

早上四点多醒来，打开 YouTube 带着耳机开始看 Apple 的 WWDC 2024，终于揭开了 Apple AI （Apple Intelligence）的面纱。没有给我当时看 OpenAI 发布 GPT-4o 时的那种「哇…」的感觉，但也能理解其从系统层面能带来的变化。

早上哈妹不想去上幼儿园，问了半天也没问出来一个理由，一会儿说自己咳嗽一会儿说觉得有的老师太严厉。到八点十五分左右，在小眼的帮助下，一起带她去了学校。晚上回来问哈妹，她还是说不出来为何不愿去幼儿园，小眼问她是不是就是单纯的觉得有点累不想去了，她回答说是的。可能她就是没啥原因，而我硬要她给了理由，然后她就找哇找？（她自己是觉得今天在幼儿园还是很开心的。

今天我的腰好了不好，基本能正常的走路坐卧了，不过坐久了或者站久了还是会有点直不起。上午开会，下午培训。一是因为效率方面的培训，二是好久没参加培训现在又开始参与进去了，有种充实的感觉。

晚上突然在想，好想尝试一下自己拍视频短片，vlog，不管是记录自己的一整天还是来练习英语之类的。

昨天的日子在今早才发现是个特别的日子，与早上看到的中国互联网的记忆正在慢慢消失，正好对照上。

白天一直在尝试如何将昨天学到的 Pydantic 方式应用到项目中，有点儿成果了，期待明天完全集成进去。

晚上小眼和哈妹要坐飞机开始吉隆坡之旅了。小眼觉得不是那么期待的感觉，不过哈妹则是很期待。晚上送她们去机场线后我便回家，她们等着凌晨的飞机。

早早醒来，想着未来找工作的事情，有点睡不着了，起来学习一下 LangChain 的基础知识。白天依旧是继续学习，在基础上做了一些尝试，但还没能将其转化为项目中的代码。

早上一进公司就有种热气扑面而来的感觉，到下午又开始变得很热了，慢慢的也待不下去。小眼早早回来，一起买水果、接哈妹、吃晚饭、收拾衣服、查看行程…她们明天就要去吉隆坡了。

今天早早的和哈妹去幼儿园，今天是带着她的被褥一起进去的。晚上她开始继续上拼音字母课了。

可能是前几天没做成什么事情，自己状态比较差，到公司后一天都不太有劲儿。不过，到晚上差不多把最近在做的事情差不过有一个结果后，内心开心了不少。

接完哈妹接小眼，小眼也感觉到很累，汇报完感觉没什么结论和希望，心累。正好一起去逛逛超市吧，买点好吃的。

哈妹洗澡时一直在听《小孩子大梦想》，她很喜欢，觉得很感动。

这几天我一直在买罗森的冰杯加上公司的咖啡来自制冰美式，感觉还不错。

小眼今天去加班，我和哈妹送她去地铁站后，在永和大王吃了早餐。上午，带着哈妹去她同学家玩儿，昨晚约了下然后今天就一直想着这事。

我在她同学家一直睡，她和同学玩儿，后面桃妈妈也去了。中午吃完饭我便回家，看了《Lost in Translation》，有被打动到。看完我又睡了一大觉，这几天主打一个困。醒来后本想独自去吃点儿粉，正好小眼在回来路上，便等她回来一起吃。

哈妹回来时，心情不好，原来是跟她的好朋友生气了，互相没能合好便分开了，她说着她们之间发生的事情时，有感到很难过。换上新衣、吃着零食、看着 iPad，慢慢的她也感到好些了。

晚上早睡。

今天儿童节，和哈妹的一整天。

上午小眼和我一起陪着哈妹去唱歌，今天就来了两个孩子，算是一对一教学了。哈妹唱歌期间，我和小眼去逛了逛、喝了个咖啡。正好那边也有儿童节活动，哈妹唱完后我们继续在那边玩了会儿。然后，我们去找好吃的，发现了一家有书有咖啡有意大利面还有猫的店。我们点了一份面，我和小眼尝了点后，哈妹一个人哈呲哈呲（辣的）的把一整盘的面都吃完了，最后把酱也收拾干净了，第一次看到哈妹吃这么多。吃完，我们顶着大太阳，骑车回家，赶着去跳舞。我太困便先回家睡觉了，这两天我都很困。

晚上我和哈妹陪小眼去美肤了一下，回来路上在生鲜汇买了好多好吃的。本想去公园边吃边玩来着，但这些好吃的还想让桃妈妈尝尝，便直接回家了。吃完饭，哈妹正跟我玩卖东西的游戏，小眼突然提议说要不直接去外面真的卖东西吧。哈妹也想尝试一把，那就开整。小眼带着哈妹收拾她不想要的一些玩具和书籍。我们提着一大袋子出门去，在家旁边的商场边，摆摊，用 iPad 打着「一元一件」的移动弹幕。一开始，我和哈妹都有点儿不太能放得开，小眼比较活跃。不过，经过了几次买卖后，哈妹开始能和顾客交流上了。后面，哈妹的同学也来一起玩了。最后，我们卖了14元，哈妹很是开心。

上午和哈妹一起去参加她幼儿园的运动会，也算是六一儿童节的活动吧。这次只有大班的孩子和家长，其他年级的孩子们则继续上课。孩子自己报名参加的运动，一人4个，以班级为单位进行比拼。哈妹选了「青蛙送回家」「贪吃蛇」「运果子」和「踩气球」。现场太吵太热闹了，小孩子们和大孩子们玩的都蛮起劲。

中午和哈妹同学一起吃饭（我们蹭饭），饭后我带着她们去家里玩会儿。下午和晚上一直在尝试 AI 的工具，但是一直没理顺也没做出啥来，虽然一直到晚上9点才回家。

下午狂风大作，毫无征兆，从公司楼上看着外面那黑云压城，实在是吓人。后面看网络上的分享，好多地方的大树都被吹倒，道路和车子都受损严重。不过，它来得快去得也快，去打球时，走在路上，之前的一切好像就没有发生过一样。

今天去打羽毛球前，正好继续看了下北京市积分落户的积分，差很多，感觉再过十年也无望。然后在骑车去打球时，我一路上骂骂咧咧。

打完球去打飞盘，这次我们人有点儿少，队里总共4个人都抽筋了，我也是其中之一。

晚上打篮球打的很累但是很爽，回公司弄了点儿上学的资料，然后和小眼去逛盒马。

上午和同事讨论完一个功能后，一起去吃饭，也聊了聊家庭的事情。收集信息，做好准备，但不要被影响。

晚上开始听 Amy Winehouse 的 Back to Black。

下午请假去参加哈妹幼儿园和社区共同举办的六一儿童节活动，哈妹跳舞。街道所有的幼儿园和小学都选送了一个节目，共有12个节目。表演开始前跟哈妹打了个招呼，表演后玩了会儿，然后跟她同学一起去吃汉堡了。我问哈妹什么感觉，激动、开心外，这次也有紧张了，她说那么多人有点不好意思。

哈妹继续在外面和同学一起玩儿，我回家小憩了会儿。在家时开始听 Nirvana 的 Nevermind，昨天听的是 Beyoncé 的 Lemonade，在了解了一点其创作背景后，感觉更能欣赏点儿了。

晚上带着哈妹去找小眼吃粉，今天看天气好，便骑电动车去。今天吃的感觉不如上次，嗦螺有点儿太辣且菜油没放够，雪菜感觉炒糊了导致粉有点儿怪味，不过最后还是吃撑了。

今天有点儿不知道该干什么，主要还是想做的东西太多，都想做但没有一个重点。早上到公司发了张照片，执行一下新的 MIND pictures。

生日快乐，生日不快乐，生日还是快乐。

白天继续处于很 down 的情绪中，一直到晚上。在哈妹给我唱生日歌时，一下子没绷住，晚上和小眼聊开来了。

晚上我带着哈妹和桃妈妈，一起去找小眼，去吃小眼觉得很正宗的湖南米粉。我们点了很多小吃，我吃的很满足，尤其是嗦螺。晚上到家，小眼给了我生日礼物，一个及时的钱包。

今天把 RAG 的内容完成了，虽然还有点不够好。

5525，回到那一天。

今天我们要去看五月天的演唱会，白天下了一天的大雨，到我们出发去看演唱会时雨便停了。到安检口，由于我们没有给哈妹买票，这次我抱着哈妹不让进去了，必须也要给哈妹买票才行。于是，我便被堵在了外面，sad。所幸，后面还是想办法进去了。

今年的舞台感觉更丰富些，我们一晚上唱着跳着很开心，虽然这次我们仨没有去年那么兴奋。

今天上午下大雨，正好今天的音乐课暂停了一次。下午带哈妹去跳舞，我们走路去的，在雨中匆匆赶路这样的氛围蛮好，而哈妹很乖的不抱怨的一路走着聊着也很让我觉得欣慰。

上午在家看了会儿语法书，小眼带着哈妹去做指甲。然后，我们一起去公司，先是吃煲仔饭，然后在公司，也就待了一个多小时，简单看了下 langchain 的内容，哈妹则是比较熟悉的去玩她的角色扮演游戏，小眼玩着手机，写完周报。

然后，我们便去太阳宫公园玩了，而这就是我们今天难忘的时光的开始。先是在公园里逛逛，越往里走越有惊喜，花圃、凉亭、溪水、喷泉……最后我们在一块草地上停留了会儿。我们侧手翻、跑步、爬、摔跤、跳山羊……我们都光着脚在草地上玩儿，很自在很快乐。我们三都有投入进去玩儿，这是我最满足的。

玩完去买牛奶，回家做面吃，然后继续去亮马河公园玩了会儿。哈妹很困了，但她还是想要继续玩完，而这也是吃饭前我们约定的，便继续成行。

这一天比较平常，除了是新的一周开始。工作效率比较低，也没有学习什么。晚上回家早，很哈妹一起练习了下舞蹈，画了画，认了动作，玩了下蛋仔派对（总是 out 导致她不想玩了，甚至要把游戏卸载到）。

昨晚的梦有点吓人，要去参加考试，但是那个地方的测试又不够，而且厕所的设计和卫生都很差。我上厕所时总是由于太多人看着而尿不尽，这样尿了一次没一会又尿一次。醒来自己是憋着尿的状态。

上午送小眼去上班，路上她突然又是生气的状态，我有点措手不及。原来，还是昨晚聊天时，不欢，还没好，甚至引发了更深的担忧。一上午互相聊了聊，也是有点相互不理解的状态。

中午和傍晚看了看 Exodus 的内容，有了一个大概，明天持续丰富一下就可以整理了。晚上吃了泡面，跟哈妹一起学习了会儿字母和文字。

昨晚妈妈给我打电话，聊了聊她最近的状态，身体不舒服有去打针，干着很多活儿让她觉得委屈，然后也抱怨了一通爸爸。

今天很累，早上九点被敲门叫醒来的，因为约了洗空调。上午洗完空调顺便打扫了一下沙发底，然后带哈妹去公司拿全勤奖。哈妹看到后，发现那么一大个，很是开心。花了一个多小时继续看如何把 LangChain 的 chat history 和 retrieval 连起来，但一直不成功。

下午去公司想做点什么，但也没做成啥。先补了下觉，然后还是想继续尝试 LangChain，继续不得法。烦躁之下，也不愿干其他事情了，便想着给 iOS 应用加了一个 haptic 的功能。

晚上被小眼叫去吃麻辣烫，她们发现了一家比较特别的店，我坐地铁过去，到了后她们也快吃完了，小眼告诉我一般般。吃完逛逛三里屯，下雨了，有点凉。我们分开回家，她们仨骑电动车我打算坐公交回家。路上看到 Butterful & Creamorous 排了蛮多人，便想着也排队买点回去当早餐吧。买完去坐公交车，路上看了眼小眼的位置，发现她还在三里屯路口，打电话过去问问情况，她情绪很激动，说找不到妈妈和哈妹了。我先是让她平静一下，等会儿我就去找她，然后给妈妈打了电话，让她把位置发给我。找到小眼后，我骑车带着她去找桃妈妈和哈妹，一路上小眼很生气，当然这也是由于担心加上沟通不畅造成的。见到桃妈妈和哈妹后，让哈妹上车，我们仨先回去了，桃妈妈坐公交车回来。

晚上睡觉时，和小眼聊了会儿这件事情，她觉得我的及时出现很神奇。后面又聊了会儿关于哈妹未来教育的问题，不欢。

周六上午带哈妹唱歌，中间隔了两周，感觉好漫长。期间我去旁边的菜市场逛了下，尝了尝尹三的豆汁儿，不好吃不过也能吃得下。回来的路上给哈妹买了根绿豆冰棍，她坐在电动车上吃着，竟然把整个裙子吃的跟玩了泥巴一样。跳完舞蹈回家，保洁阿姨来帮忙打扫卫生了，借此我们自己也收拾了一番家里，家里整洁干净了不少。我们好久好久没有花时间来打扫家里了。

晚上小姨和她男友来家里吃饭，然后掼蛋到凌晨。

周五白天的时间过得很快，一直还在学习 LangChain 中，跟着 Tutorial 走了一遍，对常用的功能已经有些了解。晚上打羽毛球，很闷热，状态一般。打完和同事去吃了个宵夜，瞎聊聊公司的事情。回去接哈妹，她还在同学家玩儿。

晚上去看了 Billy Branch and the Sons of Blues 和 Peaches Staten 合作的现场，才发现 疆进酒的英文是 Omni space。

今天我的重点在 LangChain 的实践。小眼要去吉隆坡玩，带上哈妹一起。哈妹幼儿园简短的家长会感觉有点没必要，一则通知能搞定的事，哈妹被选来跳舞。

今天最新鲜的事情莫过于 OpenAI 的 GPT-4o 的发布，早上起来把二十几分钟的发布会看完了，对演示部分大模型的实时反馈感到很震撼。

另外，Apple Music 100 Best Albums 让我很感兴趣，网站做的很酷炫。在搜索专辑并添加播放列表时，发现了 Spotify 支持 Playlist folders，这让我在收藏那些专辑时，可以将其归档在一个文件夹下，而不用让我的 library 太长。

到今天早上，终于是把 Andrew Ng 的深度学习课程全部看完了，后面就是去回顾总结一下。

今天的工作主要是跟同事同步一些想法和成果，也做了一些预设命令的尝试。晚上通过 Flask 完成了 Emotion 应用的开发，主要是练习一下通过其来构建 server。

晚上回家时去回家路上的盒马 mini 逛了一下，感到很惊喜，也迫不及待想和家人一起去逛逛。

今天哈妹幼儿园拍毕业照，她穿着裙子和公主鞋去上学，傍晚去接了下她。

昨天晚上开始，小眼就有回应我了，虽然也只是说了几句话，但能明显感觉到她的好转。今天则更进一步，可以说是完全好了，虽然面上她好像还是生气。

今天和昨天中午都有跟同事一起吃午饭，继续聊了聊我的烦恼事。
