you know those p.g.a. letters after producer credits in movies? they certify (from the guild) a person's major producing duties and decision making authority for the film.
i'm adding h.d.a. after my name in design docs / projects made assisted with AI for "human direction and accountability" to indicate:
1. AI was used
2. I was directing
3. I take responsibility

i set up a windows ec2 vm from claude web, had to use aws web console rdp to do something it couldn't. i could paste and mouse but no keyboard input? told claude and it somehow put scripts on the desktop i could run instead, including an on-screen keyboard, aww
A hyperkernel runs unmodified programs directly on hardware virtualization and serves their syscalls from a userspace kernel in the host process, which may translate to the host kernel.
Most notable examples: gVisor+KVM, hyper-linux, ...

Cybersecurity is an industry where historically, the best product has rarely won.
In a world of human-constrained attacks, cyber was still effectively a checkbox. As long as the product met a baseline functionality, the CISO said, “I have my VM/SIEM/DLP solution, I’m good to go.” In this paradigm, marketing and sales mattered way more than technical superiority.
But in a world where agents can attack your systems at massive volume and scale, the efficacy of cybersecurity products is put to the test. Even a difference of 96% vs 99% in attack prevention is magnified. Brittle solutions which can’t perform at scale will quickly be ousted and we’ll see companies that grew purely on marketing and Gartner magic quadrants sink quickly.
The cyber industry is changing, and now the best technology will win.

your read() has no idea if the file lives on ext4 or btrfs.
both go through the vfs first. it's a layer in the kernel that sits between the syscalls and every file system.
open() walks the path through the dentry cache and finds the inode. read() then calls whatever read function that file system gave the vfs.
so a new file system just plugs in its own functions. your code doesn't change.
