谷歌发布Weather Lab，利用AI提升气旋预测准确性
谷歌DeepMind与谷歌研究（Google Research）联合推出了名为Weather Lab的网站，展示其基于AI的实验性天气模型。该平台能提前15天预测气旋的形成、路径及强度，并生成50种可能的情景。
该模型已获得美国国家飓风中心（NHC）的科学验证，并向其提供实时预测数据，旨在辅助预报员做出更精准的判断。 内部测试显示，其5日路径预测精度比现有领先的物理模型高出140公里，相当于将预测水平提升了1.5天。

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
