> In electronic storage: Adding information to RAM, SSDs, flash memory, etc. — that is, storing a 1, instead of a 0 — requires storing an electric charge. Each electron has a very small weight (something like 9.10938215 × 10−31 kg), so adding electrons does mean adding a tiny amount of weight.

回复了 nigga 创建的主题 路由器 什么电脑网卡现在能支持协商 4800Mbps?
AX210 理论极限只有 2400 Mbps (2x2 MIMO, 160 MHz channel)

https://ark.intel.com/content/www/us/en/ark/products/204836/intel-wifi-6e-ax210-gig.html

AX411 支持 2.4GHz + 5/6GHz 双连接,合起来也只有理论 3000 Mbps

https://ark.intel.com/content/www/us/en/ark/products/217242/intel-wifi-6e-ax411-gig.html

目前不存在单张消费级 4x4 无线网卡,有的话可以 4800 Mbps. 年底出 Wi-Fi 7 了说不定会有

客服说的 4800 Mbps 应该是路由器多组天线加起来的速率,不是单个客户端能达到的速率

追求速度+稳定+双工的话老老实实上 10G 有线组网
@wps353 是说测试发现 UA string 改 11 后一堆网页无法正常加载。略微提升隐私是副产品
> Mozilla's Firefox team and Apple's Safari team have encountered a long tail of broken web content when the user agent string reports "Mac OS X 11_0_0" - basically, any macOS major version greater than 10. Per http://crbug.com/1175225 , both browsers have capped the reported macOS version to 10_15_7 to both work around this, and also slightly increase user privacy.

回复了 absinthe 创建的主题 macOS macOS 13.2 为什么不支持 144Hz HDR 了?
和显示器型号有关,27GP950 144 Hz HDR 可以正常开启

VRR 48-144 Hz 开 HDR 也无问题..

> 如果你的 Apple ID 已启用双重认证,则无法将双重认证关闭。如果你是无意中更新为双重认证,则可以在注册后两周内将双重认证关闭。如果关闭双重认证,你帐户的安全性将会降低,并且你无法使用那些需要更高级别安全性的功能。
