wg show

peer 下 endpoint 显示的应当就是 peer 的 external IP

可以，如果不想每台终端手动配置 DNS 的话至少有两种解决方案：

1. 主路由支持修改 DHCP DNS Server 列表的话，直接把你内网的 DNS Server IP 加进去，这样所有遵循规范的 DHCP Client 都会默认采用这个 list 。譬如我的解决方案是在 RPi 上架了个 AdGuard Home 后加到了 DHCP DNS Server list. 如果开了 DHCPv6 ，则需要同样加到 v6 的 DNS Server list:

2. 往主路由跑的 dnsmasq 里直接加静态 host-route ，例如：

cat > /run/dnsmasq.conf.d/custom01.conf <<EOF
host-record=ci-debian.mydomain,192.168.10.24
host-record=ci-debian2.mydomain,192.168.10.25
EOF

然后 reload dnsmasq

供参考。

MS Edge 支持硬解 HEVC

about:gpu 中 Video Acceleration Information 有：

Decode hevc main 48x48 to 8192x8192 pixels
Decode hevc main 10 48x48 to 8192x8192 pixels
Decode hevc main still-picture 48x48 to 8192x8192 pixels

实测 Mac Mini M1 插一台 4K 144 （ DP 到 C 口）没问题，插第二台的时候第二台（依旧是 DP 到 C 口）直接黑屏无显示，所以是只能支持一台 4K 144 输出。用的显示器是 27GP950 + 27GN950

UPnP / NAT-PMP 打洞。例

现在的路由器一般都支持，但可能出于安全原因而默认禁用。

In some permission systems additional symbols in the ls -l display represent additional permission features:

+ (plus) suffix indicates an access control list that can control additional permissions.
. (dot) suffix indicates an SELinux context is present. Details may be listed with the command ls -Z.
@ suffix indicates extended file attributes are present.

这应该是 Apple 和 Google 签作为浏览器默认搜索引擎的合同里规定了的，是 Safari 加的。

同理，用 Firefox 默认的 Google 搜索也会加 client=firefox （但可以用自定义搜索引擎的方法去掉

sudo powermetrics --samplers smc | grep -i "CPU die temperature"

2. M1 Mac 目前好像没法用自带 CLI 读取（没实现），得用 API ，见 https://github.com/yujitach/MenuMeters/commit/5604e769b9bf5cc0a5ee6f0c6f99ecca570f1b37#diff-69ec57a2eaee2a9eae215332a60e6b2ce67e378314670e5112c39029f445ab3aR54-R72

> The integer promotions
> Whenever a small integer type is used in an expression, it is implicitly converted to int which is always signed. This is known as the integer promotions or the integer promotion rule.
> Formally, the rule says (C11 6.3.1.1):
>> If an int can represent all values of the original type (as restricted by the width, for a bit-field), the value is converted to an int; otherwise, it is converted to an unsigned int. These are called the integer promotions.
> This means that all small integer types, no matter signedness, get implicitly converted to (signed) int when used in most expressions.
