New Coding Language?
Stainless
by Xeons
Stainless is an experimental general-purpose language.
It reaches for the performance of C and C++ with the flexibility of something higher-level.
It is a deliberate mongrel. The syntax, namespaces, and attributes come from C#, with one large cut: Stainless has no exceptions. The value semantics, layout, and ABI come from C and C++. Reference counting and the borrowed-parameter convention come from Swift. Monomorphized generics come from C++ and Rust. Variants come from the ML family, by way of Swift and Rust. Runtime metadata lives as plain tables in the binary, as in Swift and Go.
Where those ideas disagree, the choice is written down in the docs—along with the reason—because the interesting part of the experiment is which combinations hold together.

Windows 11 24H2 — The Hidden Hypervisor Killing Your Emulator
If you're running LDPlayer, BlueStacks, MuMu, VirtualBox, or VMware on a fresh Windows 11 24H2 install and everything is stuck, slow, or crashing — this is why.
Microsoft introduced an undocumented change in 24H2 that ties Virtualization-Based Security (VBS) to Windows Hello. Even if you've done everything right — SVM enabled in BIOS, Hyper-V disabled, Memory Integrity off, hypervisorlaunchtype set to off — the Windows hypervisor is still loading silently in the background.
Your emulator can't access AMD-V or VT-x directly. Instead it falls back to NEM, a software emulation layer that runs like garbage. LDPlayer sits at 94% forever. VirtualBox throws "AMD-V is not available." VMware says the host doesn't support virtualization. All lies. Your hardware is fine. Windows is hijacking it.
The smoking gun is in the VirtualBox log:
HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available
That line means the hypervisor intercepted your CPU's virtualization extensions before VirtualBox could touch them.
I burned hours debugging this on a brand new Ryzen 7 7700X + RTX 5060 Ti build. Every troubleshooting guide on the internet was useless. The fix was buried in a Reddit thread from late 2024 and confirmed across multiple Microsoft Q&A posts that were all marked "not answered."
The culprit is a single registry key that doesn't appear in any official Microsoft documentation:
HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\WindowsHello\Enabled
Set it to 0. That's the one everyone is missing. But it's not the only thing you need to hit — there are four phases to fully kill VBS on 24H2.
I wrote a PowerShell script that handles all of it: BCD config, the full DeviceGuard registry tree including the hidden WindowsHello key, Windows feature removal, and Group Policy overrides to stop it from coming back after updates.
Grab it here: https://sevlegend.com/?page=codes&code=Ld-amd&cp=1
After running it and rebooting, msinfo32 should show "Virtualization-based security: Not enabled" and your VBox.log should read "AMD-V is active" instead of that NEM fallback garbage.
Filed under: things Microsoft should have documented but didn't.
