中国版“星链”首批卫星成功发射

2024年12月16日,中国通过长征五号B火箭成功发射首批10颗“国网星座”低轨卫星,开启全球互联网覆盖计划。该计划预计部署12,992颗卫星,提供低延迟、高速宽带服务,构建空天一体化6G网络。

“国网星座”由两个子星座组成,分别运行于极低轨道和近地轨道,未来将支持手机直连卫星通信。此次发射标志着中国在卫星互联网领域的重要进展。

“国网”由中国政府成立的中国星网公司管理。与此同时,中国还在推进另一项名为“千帆”的星座计划,目标是部署1,300至14,000颗卫星。未来,中国需在2032年前完成一半“国网”星座的部署,以满足国际电信联盟的频谱规定。

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.

Importantly, that investor viewpoint is not new. It cycles in when conditions are right (and vice versa). It also brings the ineffective warnings of an overpriced market with it.Looking toward a good 2022 stock market, there is no apparent reason to expect these issues to change.
