太炸裂了！！！

4 月 30 日下班后刷短视频，发现了这个超级劲爆的安全漏洞：CVE-2026-31431，又名 Copy Fail。
它只需 10 行 Python 代码，就能完成 Linux 本地权限提升，直接获得 root 权限。而且这个漏洞从 2017 年就存在，几乎影响所有主流 Linux 发行版。

This is absolutely insane!!!

While scrolling through short videos after work on April 30th, I discovered this absolutely explosive security vulnerability: CVE-2026-31431, also known as Copy Fail.
It only takes 10 lines of Python to achieve Linux local privilege escalation and directly obtain root privileges. What’s more, this vulnerability has existed since 2017 and affects almost all mainstream Linux distributions.

最近半年来，由于 Denuvo 加密技术可以通过 HYPERVISOR 来绕过，已经被破解了很多游戏了。

我常用的盗版游戏网站上已经有很多 Denuvo 加密游戏的破解版本了，包括《剑星》、《红色沙漠》等等。

不知道是出于什么原因，在这个网站上并没有发布《黑神话：悟空》的破解版本。

但其实《黑神话：悟空》和其他 Denuvo 加密游戏没什么本质不同，一样可以通过 HYPERVISOR 来绕过 Denuvo 的保护。

dodi 上已经发布了《黑神话：悟空》的破解版本了，但考虑到这个网站需要魔法才能访问，我这里重新分享一下《黑神话：悟空》的破解版本。

Over the past half year, since Denuvo’s DRM can be bypassed via HYPERVISOR, quite a few games have been cracked.

Many Denuvo-protected games already have cracked versions on the pirate game site I usually use, including Stellar Blade, Crimson Desert, and more.

For some reason, this site has not published a cracked version of Black Myth: Wukong.

But in essence, Black Myth: Wukong is no different from other Denuvo-protected games — its Denuvo protection can also be bypassed via HYPERVISOR.

dodi has already published a cracked version of Black Myth: Wukong. However, since that site requires a VPN to access, I’m re-sharing the cracked version of Black Myth: Wukong here.

两个著名的 Switch 模拟器，分别是 Yuzu 和 Ryujinx。但由于任天堂的压力，Yuzu 和 Ryujinx 都停止了更新。

现在的 Switch 模拟器主要是这两个项目的分支，我这次安装的是 Yuzu 的分支 Eden 和 Ryujinx 的分支 Ryubing。

我找到了这两个模拟器的解压即用版本：

There are two famous Switch emulators: Yuzu and Ryujinx. However, under pressure from Nintendo, both Yuzu and Ryujinx have stopped updating.

The current Switch emulators are mainly forks of these two projects. This time I installed Eden (a fork of Yuzu) and Ryubing (a fork of Ryujinx).

I found portable (extract-and-run) versions of both emulators:

Operating Class（简称 OP Class）是 IEEE 802.11 标准中定义的一个 逻辑概念，它是一个监管域相关的频谱配置打包标签，它把 频段 + 信道集合 + 信道间距/带宽 + 其它行为限制 用一个数字编码起来，方便设备在不同国家和地区快速理解“哪些信道可以合法使用”。

Operating Class (abbreviated as OP Class) is a logical concept defined in the IEEE 802.11 standard. It is a regulatory-domain-related spectrum configuration packing label that encodes frequency band + channel set + channel spacing/bandwidth + other behavior restrictions into a single number, so that devices can quickly understand “which channels can be legally used” in different countries and regions.
