有媒体报道说微信开始内测「批量撤回消息」的功能，我看了下自己几个手机上的版本，都还没有被灰度到。 所谓批量撤回消息，其实是撤回消息功能的升级版，支持一键撤回一定时间内的消息。 功能操作上，会在原本撤回弹出菜单里新增一个选项，点击后会一次性撤回两分钟内的所有消息。 举个例子，有些人发消息时习惯一句话分成几段发出去，比如一句完整的话是「今天下午一起去游泳吧」，然后被拆分成两句发出去，分别是「今天下 午」和「一起去游泳吧」。 我想了下，这个功能可能对这么一类场景有帮助。 如果想撤回这句完整的意思就得连续操作撤回两次，要是正好卡在两分钟的节点上，那有些内容就无法撤回了。 因此，撤回本次发送的全部消息就能一键清除所有分段消息，从便利性来看是有所提升的。 特别是在一些讨论场景中，其中一方巴拉巴拉说了好多句，结果回过神来来发现说得不合适，于是撤回重来，那么这个功能就非常有价值。 还有就是在发文字配合图片的场景中，撤回文字和图片之前要分两步操作，现在也是一键搞定。 不过，对于大多数普通场景来说，单次撤回功能已经够用了。 微信开始内测的这个「批量撤回消息」功能属于常规功能延伸，属于有了会更好，但没有也不影响的优先级。 即便是删 ...

近年来，宠物经济的热度持续攀升，宠物用品消费甚至被称为"第二母婴产业"。除了常规宠物用品，智能宠物硬件品类成为增速最快的细分赛道之一—— 全球市场研究和咨询公司 Future Market Insights 的数据显示，2024 年全球宠物智能用品市场规模将接近 60 亿美元，预计在 2024 年至 2034 年间将以 19.5% 的年复合增长率增长。 不断增长的市场需求，也驱动智能宠物硬件品类的快速扩展：从基础照护类（如智能喂食器、饮水机、自动清洁猫砂盆）到健康监测类（可穿戴项圈、定 位追踪器、体征监测设备）；从互动陪伴类（智能摄像头、陪伴机器人、投食互动玩具）到安全管理类（电子围栏、智能门禁、走失防护设备）等……种 类繁多的新式硬件从"吃、喝、拉、玩、安"多个维度覆盖了宠物的日常生活场景，而这种趋势则为智联网（AIoT）模组及解决方案企业带来了新的机 遇。 直击行业痛点的差异化能力成为关键 宠物硬件的普及不仅是硬件制造的竞争，更是连接、数据与智能的深度融合，对模组/解决方案企业而言，单纯提供"通信"已远远不够，差异化能力正成 为未来竞争的关键。 ①多模态能力：让设备"读懂"宠物 传统的单一传感器往往只能获 ...
