沟通能力强的人，
不是会说话，而是说话有顺序。

1）先听再说
先听事实、感受、意图，再表达观点。

2）先说重点
总结在前，细节在后，让人秒懂你的意图。

3）先求同、再存异
有冲突时先找到共识，分歧才有讨论空间。

沟通不是技巧，
是让对方更容易理解你的“结构化表达”。

能说清楚的人，做事也更清楚。

The 4N25 is a reliable coupler that work as a radio PTT switch.
They provide electrical isolation between the control circuit and radio, with the phototransistor acting as a switch to pull the PTT line low.

人生建议:越是没钱，越要对钱有概念🔥

[Oliver Prompts @oliviscusAI]

There's an open-source home robot vacuum you can actually build yourself.

It's called OOMWOO.

Runs on a Raspberry Pi with 2D LiDAR mapping, ROS2 navigation, and native Home Assistant integration. No cloud dependency, no vendor lock-in.

The team spent real time researching before designing it. They reviewed the entire 2025-2026 robot vacuum market, from budget to flagship, and found real-world cleaning doesn't track advertised suction power.

The anti-tangle brush design alone is worth mentioning. A tapered rubber roller that resists hair-wrap, one of the most common complaints with commercial models, easy to 3D-print yourself.

If you've got a Raspberry Pi and a 3D printer sitting around, this is a genuinely interesting weekend project.

很多人家里都有一些"舍不得扔"的东西，旧衣服、快递盒、过期杂志、坏掉的电器……

但如果物品越来越多，已经严重影响生活却依然无法丢弃，那么就需要警惕一种精神心理障碍“囤积症”。

囤积症已被现代精神医学列为一种独立的精神障碍，其核心特征并不是爱收藏，而是持续、强烈的难以丢弃物品，无论这些物品是否真正具有价值。

囤积症的4个典型表现:

① 持续大量收集物品

不仅舍不得扔，还会不断把各种物品带回家，包括包装盒、塑料袋、旧报纸、损坏家具等。

② ��以做决���

面对任何一件物品，都很难判断该留还是该扔，哪怕只是一个空瓶子也会反复犹豫。

③ 对物品产生强烈情感依恋

很多物品被赋予了特殊意义，患者会认为它们代表安全感、回忆，甚至是自我的一部分。

④ 生活空间受到严重影响

随着物品不断堆积，房间逐渐失去原有功能，床不能睡、厨房不能做饭、通道无法正常行走，甚至影响家庭关系和人身安全。

那么，为什么会出现囤积症？

目前认为囤积症通常由多种因素共同作用，包括以下5点：

决策能力和执行功能下降；
对物品价值的认知偏差；
焦虑和完美主义倾向；
创伤经历或重大生活事件；
遗���及神经生物学因素。

值得我们大家注意的是囤积症并不是简单的懒或不会整理，而是一种需要专业干预的心理疾病。

如何治疗？

目前证据最充分的一线治疗方法是认知行为疗法（CBT）。

治疗重点包括以下：

帮助患者识别"必须留下"的非理性信念； 学习更客观地评估物品价值；
逐步练习整理和丢弃物品；
降低因丢弃物品产生的焦虑；
建立新的决策模式和生活习惯。

对于合并明显焦虑、抑郁或强迫症状的患者，医生也可能会根据具体情况配合药物治疗，以提高整体疗效。

Rust is no longer just for MCUs. It's coming to sensors too.

STMicroelectronics has officially introduced platform-independent Rust drivers for its MEMS sensor portfolio.

Why this matters 👇

- Memory-safe drivers written in Rust
- Platform-independent architecture
- Supports both SPI and I²C
- Published on crates. io and GitHub
- Covers motion, environmental, infrared, and biosensing MEMS devices
- Works alongside existing Rust embedded ecosystems like Embassy
- ST will continue maintaining its C drivers while expanding Rust support

Why embedded developers should care:

- Fewer memory-related bugs
- Better code safety and reliability
- Easier driver reuse across projects
- Modern package management with Cargo
- Stronger foundation for safety-critical applications

The trend is becoming clear:

- Espressif → Official Rust ecosystem
- ST → Official Rust MEMS drivers
- More silicon vendors are embracing Rust every year
