Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

AMD's Anti-Lag feature is getting gamers banned from Counter-Strike 2
Nit: AFAIU there is no literal modification of machine code going on—instead the import address table (IAT, the Windows counterpart of Linux’s GOT) is patched (the Windows tradition calls this “detoured”, from the quite popular Microsoft hack[1] that does it).

Any sufficiently advanced uninstaller is indistinguishable from malware
You essentially replace a function with your own. The project is at https://github.com/microsoft/Detours.
I’ve created a PowerShell module that wraps this library to make it easier to hook functions on the fly for testing https://github.com/jborean93/PSDetour. For example I used it to capture TLS session data for decryption https://gist.github.com/jborean93/6c1f1b3130f2675f1618da5663... as well as create an strace like functionality for various Win32 APIs (still expanding as I find more use cases) https://github.com/jborean93/PSDetour-Hooks

But the client is much different now, and most of that won't work anymore. The client is heavily obfuscated and you can't use a packet sniffer, the communications are encrypted, you CAN however use things like Microsoft Detours to peek at communications

Hooking 🪝
If you mean is there an API to perform hooking, then I think the answer is no. There are libraries for doing this, including the official MS one: https://github.com/microsoft/Detours

It looks like League of Legends' source code has leaked and is up for sale online
That's how things like steam or Nvidia overlays work, or fraps or OBS hook the output buffer; you can use official packages published by Microsoft for that, such as Detours.

Having too many (1,000+) Microsoft Edge tabs open can break File Explorer in Windows 10
Inject a DLL into the process. The DLL hooks two API functions, RoGetActivationFactory() and RoActivateInstance(), using Detours library. When a WinRT class ID is passed in, compare it with WindowsUdk.UI.Shell.WindowTabManager, and if equal, return an error code.

Is it possible to edit the XAML of the Win11 Taskbar?
3. Manual hooking (Not recommended): It's possible to use some hooking library like Microsoft Detours to hook the functions responsible for creating the UI layout. I highly unrecommend this method as it's the most method prone to be broken by any change Microsoft does.

Is there a tool that you can attach to a game EXE file directly and it ll show you incoming and outgoing traffic for only that file?

Using Landlock to Sandbox GNU Make
> With regards to chroot, I stand corrected. I knew it was a tree of symlinks, but I thought it was also more than that because symlinks alone don't seem like a sandbox. Honestly, Cosmopolitan's system appears to be more of a sandbox than that.
To be totally clear: the tree of symlinks thing is a fallback, used only when lacking platform support or when sandboxing is explicitly turned off [0]. On Linux, the normal sandboxing strategy is to use namespaces, like most container runtimes. On Mac it apparently uses sandbox-exec (some opaque Apple tool), as was mentioned above. Chroot, being both non-POSIX, requiring root access on many systems, and not providing the necessary facilities is not really a great fit -- which I assume is why it's not used.
There was experimental Windows sandbox support at one point [1] based on how MS does it for BuildXL (their own build tool for giant monorepos) [2]. Unfortunately it doesn't seem to be maintained, and under the hood it's kinda ugly -- it actively rewrites code in-memory to intercept calls to the Win32 APIs [3], which was apparently the cleanest/best way MS could come up with. However, from Bazel's POV it works in a roughly similar way -- you spawn subprocesses under a supervisor, which is in charge of spinning up whatever the target process is with restrictions on time/memory usage/file access.
On the "sandbox in the interpreter" thing: what kind of checks are you envisioning? It seems like putting checks at that level would end up leaving a lot out -- the goal of any build system is to eventually spawn an arbitrary process (Python, gcc, javac, some shell script, etc.) and so even with extensive checks in starlark you'd end up with accidental sandbox breaks all over the place. For pure starlark rules you could e.g. check that there are no inputs from /usr, but even then if gcc does it implicitly, you're SOL. Or am I thinking of the wrong kind of checks?

Any material on how hacking works with C#?
Memory manipulation can be done very easily by pinvoking Read/WriteProcessMemory(), but it's not really fun nor very powerful, you'll almost always need to hook some function, and for that you'll need some form of binary patching or DLL injection. The latter is not practical to do in C# because it depends on the CLRuntime, which would require a loader written in a lang like C++ anyway (take a look at this dead project). Idk any tutorials but take a look at Frida.re, Ghidra and maybe CheatEngine.
- A while back I made a library to make webhooks easy to implement. I'd love some feedback from you guys
- Magpie allows FSR Modded into any Windows game (Open Source & Free)

I created a solver for huniepop on a weekend because I suck at finding chains/cascades.
Example: https://github.com/EasyHook/EasyHook/issues/16
What are some alternatives?
Mhook - A Windows API hooking library
Magpie - An all-purpose window upscaler for Windows 10/11.
orbit - C/C++ Performance Profiler
Magpie - 使游戏窗口全屏显示
pe-sieve - Scans a given process. Recognizes and dumps a variety of potentially malicious implants (replaced/injected PEs, shellcodes, hooks, in-memory patches).
gamescope - SteamOS session compositing window manager [Moved to: https://github.com/ValveSoftware/gamescope]
pmaudit - "Poor Man's Audit" (lightweight build-auditing script)
Magpie - English Translation of Magpie
samurai - ninja-compatible build tool written in C
gamescope - SteamOS session compositing window manager
WidescreenFixesPack - Plugins to make or improve widescreen resolutions support in games, add more features and fix bugs.
Match3Solver - A solver for the game called HuniePop 2. It injects to the game to capture the board state and shows possible moves with options to sort based on your priority.
