比亚迪第1400万辆新能源车在巴西下线，巴西总统卢拉在现场激情演讲：（一语双关的说）饿着肚子可没办法好好演讲！今天是我最难忘的一天。我们要深化和中国的关系，我视习近平主席为我的挚友！ 巴西捍卫多边主义，巴西选择与中国合作共赢，这是作出了正确的选择，合作共赢，过好日子，不饿肚子！
AI 辅助阅读，在经历了 31 次尝试后终于在 github action 成功编译和公证了 macOS 的 arm 和 x86_64 版本，有需要的可以体验一下，基本可用，可能还有很多 bug 和需要优化的地方，会持续维护。
Interesting article in the September 2025 edition of "IEEE Aerospace and Electronic Systems Magazine" shows it's possible to use signals from LEO satellites like Starlink and Iridium for navigation and timing. They managed to get to ~7m of positioning accuracy without GPS.
前几天看到别人分享的一篇 《Indefinite Backpack Travel》 背包极简旅行 jeremymaluf.com/onebag/ 深得我心，作者这篇文章维护了十年，不断更新，已经有数百万人看过了，旅行的时候极简主义，就是一个双肩包，装下所有需要的东西。我每次旅行也是只背包，尽量带少的东西，行动方便，随时想走就走。…

google 的 cdc-file-transfer 是一个文件同步程序，亮点是比 rsync 的速度快几倍。那么它是如何实现的呢？ rsync 是一个非常悠久且高效的远程文件（夹）同步程序，当它发现某个文件数据改变需要传输新内容时，它并不会整个文件上传，而是把文件按照固定大小（比如100 kb）切分并结算每一块的hash
FPAAs (Field Programmable Analog Arrays) are promising as a concept, but they’ve never really taken off in the DIY/hobby electronics world. To my knowledge, the last big push was by ZRNA Research (zrna.org) about 6 years ago. 🤷♂️
这就是我平常的桌面工作环境 1. 右边是太阳神机箱 + AMD 9950X 的芯片 + 华硕的主板，主要用EndeavoursOS + Emacs来编写程序。每天都卖货，好久没有碰代码了 2.…

Current antenna upgrade path: Small → big → absurd → ‘why is it pointed at the wall?’ Answer: because walls mean nothing to this WarDragon. 🐉🔥 #DragonOS #WarDragon #SDR #EW
Another interesting talk from GRCon25: Antenna pattern mapping for radio telescopes, using an RFSoC on a drone! It's almost like a flying VNA. "hxxps://events.gnuradio.org/event/26/contributions/774/"
Interesting talk from GRCon25 on building a ground penetrating radar using a bladeRF SDR, TSA600 Vivaldi antennas, and GNU Radio. The goal: to detect shallowly buried objects. (Link in the comment)
The most famous bodyguard of PresidentPutin !🇷🇺❤️
How to Build a Car isn’t just about cars; it’s about invention under pressure. What it actually shows: Curiosity → childhood sketches turned into race-winning machines Obsession → every tiny detail in aerodynamics matters Constraints → strict rules forced sideways innovation…
