陕西柞水高速垮桥《灾害调查评估报告》公布。
洪水冲击使10号桥墩桩基折断倾倒、桥梁垮塌。20:49至21:03间25辆车坠河，62人死亡失踪。
测算垮桥原因：流水压力占35%。树木等漂流物在桥墩处形成12.8m × 3m的“挡水墙”，其推力占57%。另外，桥梁未按图施工，系梁本应埋在河床下3m，实际埋在河床表面，洪水冲刷河床降低系梁悬空，加剧漂流物壅塞，此因素占比8%。
高速与省道路基形成局部汇流区；桥墩初步设计是“斜交斜做”，施工图阶段改为“斜交正做”，增大了阻水比。
工程未向水利部门申请涉河建设项目许可。地方水利部门未有效治理非法采砂。
事发桥梁在两个摄像头背向之间，不在监控区域。

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
Telegram has exploded as a hub for cybercriminals looking to buy, sell and share stolen data and hacking tools, new research shows, as the messaging app emerges as an alternative to the dark web.An investigation by cyber intelligence group Cyberint, together with the Financial Times, found a ballooning network of hackers sharing data leaks on the popular messaging platform, sometimes in channels with tens of thousands of subscribers, lured by its ease of use and light-touch moderation.竹新社 from no
