老毒物

天呐，海底光缆统治世界的时代要结束了，又要见证历史了🤯。。 马斯克首次公布 Starlink V4 的极端参数：性能直接跳涨一百倍，光速天然快了一点四倍且不用绕大陆架，上千万条激光链路正在把地球通信主干搬上深空。 绝大多数人至今依然以为，星链只是给偏远山区、游艇和飞机提供网络补丁的边缘工具。 直到马斯克刚刚在最新的投资人会议上摊开底牌，很多人才第一次看懂 SpaceX 真正的阳谋：把构筑人类现代文明的海底光缆网络，从大洋深处连根拔起，彻底搬到太空。 这里藏着一个极度反直觉的物理常识：
光在太空真空中的传播速度，比在玻璃光纤里整整快了 40%。 
更致命的是几何路径的差异。海底光缆必须顺着大陆架和海沟蜿蜒曲折地绕远路，而太空中的卫星激光链路，两点之间永远是沿着大圆航线在真空中直线对穿。这意味着在跨洋超长距离通信上，太空激光的延迟天然比地面光缆更低。 而阻碍这件事过去的唯一瓶颈，是带宽密度。 马斯克这次直接给出了技术迭代的量化终局：
从 V2 到即将落地的 V4 卫星，单星吞吐能力将直接迎来 100 倍的暴力跃升。
在更长期的宏大蓝图里，超过 10 万颗卫星组成的轨道阵列，每颗都将配备大约 100 个传输速率超 10 Tbps 的光学激光器，在地球外围织成一张百 Exabit 级别的无缝高速网状路由。 这已经不是在做卫星宽带了，这是在用火箭把全球互联网的核心骨干网整个重写一遍。 海底光缆容易被地质地震震断、被船锚挂伤，更深陷地缘博弈的物理封锁；而悬在头顶的真空激光网络，既没有折射损耗，也没有无法逾越的地理边界。 人类用了上百年时间，把铜线和光纤一根根沉入海底来连接彼此；而未来的文明动脉，注定要在没有阻力的星空里以光速奔流。

凭什么说这是终结者2最绝的智斗名场面？！

我发现因为国内自媒体的造谣，许多中国网友对联合国教科文组织的“申遗”政策有重大误解。申遗不是申请商标或专利，根本谈不上“偷”或“抢占”。UNESCO明确规定：非遗申报没有排他性，不问最早出处，只要有助于体现文化多样性和人类创造力、得到社区的广泛参与和认同，便可申报。2005年韩国端午祭成功申报，2009年中国端午节同样成功申报。你只知道日本“偷”，是不是不知道中国2005年申报了木卡姆音乐后，阿塞拜疆、哈萨克斯坦、伊拉克等国也相继成功申报？他们也没骂中国“偷”啊？ 非遗不是一个死的文物，其特点就在于活态性，谁也占不了。联合国教科文组织和各成员国（包括中国）一直承认同一文化可能在多地有不同形态流传，其“源流”往往是多元而非单一的，因此，UNESCO公约明确鼓励拥有同一遗产项目的多个国家联合申报。我搞不懂了：一个联合国和中国政府都支持多元文化共同发展的好政策，怎么被你们这些傻逼在网上搞得好像小孩吵架一样：要么我是你儿子，要么你是我儿子，必须斗个你死我活而没有共存可能？就这么乌烟瘴气？

Yıllardır çocuk sahibi olamadığı için eşini suçlayan bir kadın, aklına en son gelen ihtimali düşünüp yatağın içine bakınca hayatının şokunu yaşadı;

On the last day of her 17-year career, a jail supervisor walked a 6-foot-9 inmate out the door by herself. She told coworkers she was taking him to a mental health evaluation. There was no evaluation. April 29, 2022. Lauderdale County, Alabama. Vicky White was 56, the jail's assistant director, and due to retire that day. Casey White was serving 75 years and waiting on a capital murder trial. Inmates going to the courthouse are supposed to have two deputies with them. Nobody questioned her. She was the boss. In the video below, the jail's own cameras watch her lead him out in his orange jumpsuit, put him in a patrol car and drive away. The plan had been running for weeks. She sold her house for $95,550, less than half its assessed value, and pulled out the cash. When deputies finally checked the courthouse schedule, there was nothing on it. By then the patrol car was already sitting abandoned in a parking lot. They disappeared for 11 days. A car wash worker in Evansville, Indiana, recognized them. A police vehicle rammed their Cadillac into a ditch. Inside: wigs, guns and thousands in cash. On the 911 audio you hear her voice: "Let's get out and run." She didn't. She shot herself in the car. He came out in handcuffs. Seventeen years of trust opened that door. How do you check someone nobody thinks to check?

【衝撃】空気より軽い断熱材、爆誕 空気より軽くて宙に浮く断熱材とか、初めて見た。これエグいな。部屋にこれたくさん浮かべたい。なんかとりあえず間接照明とセットで、明かりをつけると宙に浮く雲みたいなインテリアつくってほしい。
