今天看到苍鹭群体繁殖的规模和育雏的部分瞬间。巢中的小鸟和成鸟已经很像了,有模有样的在那里发着呆。

目力所及的到几株树上已有百余只。

一下看到这么多苍鹭我有些震撼,上一次关于苍鹭的震撼还是在龙潭西湖公园看到它。

它出现之后夏季,我都可以在龙潭西湖看到它,这样的情况在近三十年是没有过的。

环境的改变是显著的,面对这些变化也伴随着人类技术的进步与观测尺度深入,人类与动物、自然环境的关系也会有着更多问题。

前天参与户外活动,在分享的时候,比起已经成文的知识点,我更希望在了解理念的同时,别忘了思考和判断得出属于自己的结论。

你不知道的冷知识 Telegram | DID YOU KNOW?

Date: |

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.

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.
