Collagen synthesis in the human body can be aided by hydrolyzed collagen, Vitamin C, zinc and copper.
The near-infinite flexibility of OpenEmbedded/Yocto is a blessing and curse.
The Yocto autobuilder [1] covers board families, but hardware-specific layers [2] and BSPs are maintained by vendors and consultants [3].
Wind River Linux [4] offers long-term commercial support for regulated industries, derived from Yocto LTS, https://www.windriver.com/products/linux
Some work was done on a "Reference Binary Distro" to make Yocto more accessible to new developers, https://www.youtube.com/watch?v=7plHWCHGv1c
Funding has slowly diversified beyond hardware vendors, e.g. https://www.sovereign.tech/tech/yocto

What advice would you give to a younger L. E. Modesitt, Jr. at the beginning of his writing career?

> An investigation by The Sunday Times has revealed that pregabalin has the fastest-rising death toll of any drug in the UK, based on figures compiled from official data across all regions. It is detected in a third of all drug-related deaths. In 2012, pregabalin was indicated in nine fatalities. A decade later, in 2022, the number had risen to 779, with almost 3,400 deaths in the past five years.

> Gabapentin, sold under the brand name Neurontin among others, is an anticonvulsant medication primarily used to treat neuropathic pain and also for partial seizures of epilepsy.. is [ONLY] moderately effective: about 30–40% of those given gabapentin for diabetic neuropathy or postherpetic neuralgia have a meaningful benefit.
Those with peripheral neuropathy should audit the total amount of Vitamin B6 in their diet and daily supplements. Try to keep the daily amount below 10mg. There have not yet been lawsuits to add bottle label warnings, but Australian regulators have issued a safety warning.

> Vitamin B6 (pyridoxine) is in lots of multivitamin and mineral supplements that can be bought in supermarkets, health food shops and pharmacies without a prescription. Many people are not aware that vitamin B6 can cause peripheral neuropathy, which results in tingling, burning or numbness usually in the hands and feet. Taking vitamin B6 even at low doses can cause peripheral neuropathy but people are more likely to get it if they are taking more than one supplement.
This has so much potential, but it will require a workflow for Alexa to learn about specific objects and layout (of multiple objects) within the customer's home. Apple's "live audio descriptions of video" had similar promise at launch, but hasn't evolved beyond the launch demo, https://support.apple.com/en-ca/guide/iphone/iph32deb9296/18.... Could Alexa+ enable self-service RLHF on home video/images?
It's a testament to the latent market opportunity that Amazon has sold 500+ million devices, despite the obstacles that greet customers trying to customize Alexa for their specific needs. With open developer interfaces, Alexa could have been the "IBM PC" of voice AI, instead of just another walled garden.

In theory, Home Assistant voice hardware could be integrated with local LLMs for private voice control, https://www.home-assistant.io/voice-pe/
> Fully open software, firmware, and hardware.. Grove port for connecting sensors and a 3.5mm headphone jack for connecting external speakers
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 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.

1. Schedule/ask cooker to start, then stop after fixed time.
2. Blind person can control microwave with voice.
3. Blind person navigation via prompts from multiple Echo devices.
4. Blind person notification when doors opened or motion detected.
5. Blind person item locator, via Tile + Alexa.
6. On-demand instructions for caregivers.
7. On-demand physiotherapy exercise instructions.
8. On-demand streaming radio and podcasts.
9. TV voice control via Logitech Harmony or Android Fire TV.
10. Call PSTN phones via VOIP (10 number limit).
11. Zigbee devices with USA-based cloud security (Echo4 is a hub)
12. Arm/disarm Blink cameras.
13. AC/heat control via temperature sensor in Echo devices.
14. Announce notifications from Google Calendar.
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.
> These would be tough as they are based on a proprietary ASIC which is poorly documented even for internal developers. Ask me how I know.

For vision-impaired people, NFC tags can be attached to objects and the phone can read an audio description when the object is tapped against phone.
> DFU or Device Firmware Upgrade mode allows all devices to be restored from any state. It is essentially a mode where the BootROM can accept iBSS. DFU is part of the SecureROM which is burned into the hardware, so it cannot be removed.
