Maintain Technological Leadership: Subscribe to Tom's Hardware Bulletin
安全研究团队Photon在四月六日发布的报告中指出，苹果电脑操作系统存在一个可能导致网络功能瘫痪的TCP组件缺陷。该问题源于苹果XNU内核中某个32位计数器的设计局限，当设备持续运行达到特定时长（49天17小时2分47秒）时，系统内部的TCP计时器会停止运作，致使特定状态的TCP连接无法正常释放，最终造成临时端口资源枯竭，系统将无法建立新的TCP连接（仅ICMP等少数网络协议不受影响）。经Photon验证，此问题至少影响macOS Catalina 10.15及后续版本，早期版本是否受影响尚不明确。该缺陷不会引发系统崩溃或生成明显错误日志，属于隐性故障，导致用户难以快速识别问题源头。

这起诉讼与针对OpenAI和Character.AI的类似案件形成呼应。去年美国联邦贸易委员会已对鼓励情感依赖的"伴侣型"聊天机器人展开调查。
Use these tools to download videos from ThreadsLike most of my social media feeds, my Threads feed is also full of cat videos. When I see one I like, I sometimes download the video to watch later. As you may know, Threads doesn't support media downloads, which means that you'll need to rely on third-party tools to download videos from the app. You can try Threads Downloader on Android, or the Threads Download shortcut on iPhone. Using the Android app is simple enough: Just copy the Threads link and paste it in the app. On the iPhone however, you'll have to download two other free apps: a-Shell mini and Scriptable to let the shortcut do its thing. After the shortcut is set up, you can hold the share button under any Threads post, and select the "Threads Download" shortcut from the share sheet to start the download.
