再次提醒大家，避雷网迅科技网卡
被国产网卡坑的够呛。 某个项目用了网讯科技的网卡。服务器配置IP后，隔三差五出现灵异现象，包括但不限于： ICMP通TCP不通；TCP通ICMP不通；ARP/DHCP不响应... 开始时怀疑是网工的配置问题，直到我们花了一周时间把现场的网络设备配置都查遍也没找到问题后，开始怀疑NIC 换Intel网卡，问题解决
在嵌入式领域 1. (几乎)所有需求都可以找到一个rust crate 2. (几乎)所有的rust crate都至少存在一个bug 最近在项目中用ftdi-embedded-hal 时发现的bug表明，这个库虽然存在，但压根就没人试过SPI clock idle high 的场景 github.com/ftdi-rs/ftdi-e…
OpenDAL 的一个绝佳应用场景，引入成本不高，但收益显著
最近开源了一个MoE模型的EP推理引擎github.com/expert-kit/exp…，主打低成本和弹性扩展，在推理环节通过在线扩缩容充分利用多样性算力。 近日跑通了DS-V3 671B 的推理，在1张24G 4090 + 5台DDR4 x86 Server 的环境中实现了~35TPS 的Prefilling 和 ~2TPS 的Decoding 欢迎感兴趣的朋友跑Tutorial
笑死🤣，真的是这样
CSS也是前端程序员的噩梦 CSS写好的难度，个人感觉是超过Rust的
用embassy-rs 做了3个小功能, 分别涉及DMA, Timer 和QSPI，提了3个Fix PR Bug Free 的概率是0% 唉，这就是Embedded Rust吧🥲
摸索了手焊 UDFN4(1mm x 1mm) 封装的工艺 回流焊时元件的自动复位在显微镜下观察非常有趣😻
用async rust写单片机固件非常之妙，非常完美的抽象了并发语义 embassy-rs 库的开发者也很活跃，中午提Patch下午就能合（相比之下隔壁的 stm32-rs 处于常年无人管辖状态，交了Patch如石沉大海😾 github.com/CNLHC/stm32u5-…
被@DVCorg dvc浪费了一个早上，感慨一下 1) 在复杂项目里类型系统很重要 2)不完整的类型可能还不如没有类型 3)感觉dvc亟需依赖一下@OnlyXuanwo 的@ApacheOpenDAL: 依赖被数据库所使用的高质量DAL，比起自己手搓一堆质量堪忧的轮子来说要好不少吧 github.com/iterative/dvc/…
加密芯片这样的高定产品强制要求去谈可以理解，但对于SOC、FPGA这样的通用产品，国内还是还通过隐藏Datasheet强迫用户找销售的方式感觉很奇怪 另外在询盘时，国内的销售经常在有了意向型号后还是查户口式的问要干嘛要多少，但凡不是一开始就订个大几千片，就摆出一副爱理不理的态度，体验不是很好😅

能有probe.rs 这样好用的工具，Embedded Rust 的希望更大了 体验后感觉比 OpenOCD 好用很多。做到了开箱即用，扩展性也更好
为什么全志、瑞芯微这样产品力很强的公司，官网连像样的Datashee和选型手册都找不到🤨？ 感觉不像是做不好，更像是刻意在提高获取这些资料的难度，有无业内人士知道这样做的动机？
