Welcome new followers!
I am a security researcher known for the USB armory and TamaGo project among other things.
I enjoy finding unconventional ways to secure things once and for all.

I am excited to announce that we are partnering with AI Foundry to bring bare metal Go to their ET platform!
Our journey started with a lonely core and now we have the chance of hitting 1088 on the ET-SoC-1! What a privilege.
I look forward to this!

I also released go-boot v1.4 to support pure Go unikernels under AMD SEV-SNP.
UEFI is required at boot to access SNP Secrets page, then you can either remain in the same unikernel (exiting EFI Boot Services) or jump to another TamaGo unikernel ;)

And following Go 1.25.6 release, TamaGo package and compilers 1.25.6 are released as well.
This release brings pure Go unikernels to Google Compute Engine and AMD SEV-SNP support (both in GCP and local QEMU)!
Following this TARGET=gcp is now added to:

TamaGo AMD SEV-SNP support is now tested on physical servers.
This is a networked pure Go UEFI unikernel, launched under QEMU with AMD SEV-SNP, obtaining an attestation report and performing its online verification.
Transparent, reproducible, pure Go Confidential VMs!

And with the full Go ecosystem at this level this also becomes an unbeatable AMD SEV-SNP auditing/fuzzing environment.
TamaGo unikernels can now run in confidential AMD SEV-SNP VMs!
Here's a UEFI bare metal Go unikernel performing a successful attestation request!
Our next releases will include drivers and documentation for AMD SEV-SNP support.

I'm running a TamaGo VM on Google Compute Engine. No CVEs to worry about other than Go ones, just own code and runtime, starts and reboots instantly.
Open with no-auth SSH. As a cybersecurity professional this would be unthinkable, but TamaGo brings tattack surface close to 0.

TamaGo on arm64 is progressing fast, we now have interrupt handling.
I also got a hold on the new @arduino UNO Q. Would you like to see TamaGo running on it?
