LibVMI-based debug server, implemented in Python. Building a guest aware, stealth and agentless full-system debugger.. GDB stub allows you to debug a remote process running in a VM with your favorite GDB frontend. By leveraging virtual machine introspection, the stub remains stealth and requires no modification of the guest.
A modern virtualization architecture can be found in the OSS pKVM L0 nested hypervisor for Android Virtualization Framework, which has some architectural overlap with HP/Bromium AX L0 + [Hyper-V | KVM | Xen] L1 + uXen L2 micro-VMs with copy-on-write memory.
A Bromium demo circa 2014 was a web browser where every tab was an isolated VM, and every HTTP request was an isolated VM. Hundreds of VMs could be launched in a couple of hundred milliseconds. Firecracker has some overlap.
> Lastly, this approach is almost certainly more expensive. Our instances sit idle for the most part and we pay EC2 a pretty penny for the privilege.
With many near-idle server VMs running identical code for each customer, there may be an opportunity to use copy-on-memory-write VMs with fast restore of unique memory state, using the techniques employed in live migration.
Which is fine (although these routines are very slow, which makes it awkward to use for volume adjustments), but why make things so complicated when the possibility to adjust the volume in 1% steps via the app and 3% via buttons exist?

If Amazon would open up their devices and/or APIs, much much more is possible. There are some workarounds via HomeAssistant.
> The report also highlighted the dire need for this [AI] version of Alexa to make money to keep the voice assistant alive.
The early iPhone left doors open for experiments that could later be supported and productized. Alexa failed to open up devices for experiments that could seed innovation. Look at the failure of the official "Skills" program, compared to the thriving HomeAssistant ecosystem that is an obvious match for smart speakers.
If the device fails, 500K devices should be unlocked for use with generic Linux, instead of being relegated to landfill.
It was the second sentence in the article: "Amazon claims it has sold more than 500,000". 500m units in 4 years would have been an unqualified success. I don't even think the iPhone sold 500m in its first 4 years.
Yikes, that ASIC is so advanced that any product built around it will in some ways be designed for the landfill far more so than an equivalent that was generic.
