Today, I drove on the road for the first time by myself. Though my instructor was in the passenger seat, I felt nervous from the start. Every lane change, turn, or U-turn made me panic, forget to check my surroundings, or freeze. The two-hour session was tense, but also rewarding. I realized that, beyond my mindset, my driving skills need a lot of improvement. I’ll keep practicing to get better.

In the morning, Hamer was doing her homework when I left for driving practice. She and Xiao Yan later went to Pop Mart and the mall, returning in the evening.

After lunch, I lay down on the sofa to rest and watched a movie until around six in the evening, when the exhaustion finally started to fade away.

Yesterday, Hamer woke up exceptionally early and was ready for school by 7 AM, but arriving too early prompted her teacher to ask us not to repeat it. I reassured Hamer that I’d keep her company in the mornings if she wanted to wake up early. Later, our product’s new version was released, marking the end of one phase of work.

Today, after a late start due to a midnight meeting, Hamer made a toast breakfast. In the afternoon, we met her best friend after dance class, enjoying a park stroll and roast duck. Meanwhile, I explored building iOS apps with Cursor, gaining insights after initial challenges.

Web-to-App Linking

Situational Awareness

This morning, Hamer had a mild nosebleed but quickly recovered with Xiao Yan’s help. She got ready for school, and I started my day listening to an English news podcast, Up First, which has become a refreshing morning habit.

At work, I focused on the App Link, identifying potential bugs and improvement areas, which fueled my motivation.

On the way to the gym, I had the idea for an app to help parents and children learn Chinese characters. After returning home, I dove into building a prototype, using Cursor to write code, and got fully immersed in the project.

中学生能看懂：Sora 原理解读

Key steps and technology behind Sora video generation:

1. Input Data Processing: Using a video compression network to compress images or videos into low-dimensional representations, simplifying processing while retaining rich visual data.
2. Spatiotemporal Patch Generation: Sora breaks down the compressed data into spatiotemporal patches, capturing both spatial and temporal information for complex video content.
3. Text-conditioned Diffusion Model: Sora uses text prompts to guide a Diffusion model that progressively denoises and generates visual content matching the text description.

Driving Instructors

• 易通行汽车陪练
• 雷厉风行汽车陪练
• 手把手汽车陪练

This morning, Hamer woke up early, getting herself dressed and packed with a joyful energy that warmed my heart while I enjoyed some extra sleep. On the way to school, the soft pink glow of the rising sun made the morning feel particularly gentle.

At work, I finished the Popup content, though I felt fatigued in the afternoon from missing a nap. In the evening, after shopping at Hema, we ended up making noodles at home.

Hamer’s upper left incisor started to loosen, and I looked into finding a driving instructor, planning to schedule a trial session this weekend.
