tekgnos··on Taking my diabetes treatment into my own hands
It’s all vibes! Type 1 here for 28 years.

You are on the right path here but I think you are missing the “big players” for lack of a better term. The prediction software available now (open source) is quite good and works with different types of CGMS and pumps. You are really going to want to look at Loop.

Loop basically collects the inputs in the app automatically for insulin if you use a pump. I’m on the Omnipod DASH and Loop works with a few, Omnipod being my favorite. You can also input injections. It can also collect CGMS data automatically from that system. It works with Dexcom and others (I think Libre). You manually input carbs, and you are still gonna do that based on VIBES. After that, you get these magic prediction lines that show you where you are headed. And with the pump, it can add or lower insulin amounts (closed loop mode) to keep you in range. Pretty common to be 75-90% in range!

tekgnos··on Show HN: TensorDock Core GPU Cloud – GPU servers from $0.29/hr
I agree, it is always cool to see GPU offerings. How is this different from Vast.ai (mentioned 4 months ago here on HN)?

Vast has RTX 3090 GPUs for $.32/hr on-demand or $.18/hr for interruptible. You can see live available offers on the website right now.

tekgnos··on DALL-E 2 open source implementation
If you have some command line experience you can rent out some compute and then run it on rented hardware. I am renting an A40 with 48G of vram for $0.40/hr on Vast.ai right now to make cool images. I am still using Big Dream which I think is still based on DALL-E, not DALL-E 2. I couldn't figure out how to run this latest iteration (yet!).
tekgnos··on Vitamin D deficiency and Covid-19 mortality [pdf]
Agree, it is a theory and one I believe. Also how/why white skin evolved is another data point to consider. Lighter skin means more Vitamin D in the summer months which is vital for humans in northern latitudes.

Clothes sure, but still were outside in the sunlight during most of the day without sunblock. Take a look at hunter gather tribes still alive today. Not a whole lot of clothes! But sure, some.

That's fair. The RDA at 400 is tiny.

Sure, there has been evolution. Like the adaptation of white skin for humans in northern latitudes. Why was it so important to evolve pale skin for humans living in high latitudes?

Social distancing in summer as a reason why people don't get sick is an interesting theory, any studies that support it?

Studies of pale skinned Norwegiens who go in the sun during summer show they make 10,000-20,000IU equivalent a day. Results will vary depending on skin tone and the position of the sun (lower in the sky means no vitamin D as the right wavelengths of light are not hitting your skin)

tekgnos··on Vitamin D deficiency and Covid-19 mortality [pdf]
It is not surprising at all that Covid-19 matches what we already know about Vitamin D and Influenza. There are consequences for radically altering the environment in which humans evolved. We were nude outdoors and now we are clothed and indoors. When we do briefly go outside, we are all conditioned to slather on sunscreen, which blocks all Vitamin D generation.

Why do people tend to get sick in the wintertime and not the summer?

This study used a tiny amount of Vitamin D (2,00IU/day) which is absolutely not enough Vitamin D to have any affect on someone who is deficient. Going outside in a swimsuit produces 10,000+IU equivalent. We evolved nude, outdoors.

tekgnos··on Fly Like You're Rich With Social Flights (And Private Planes)
You guys are missing the major cost savings while pouring over the numbers. It all comes from empty private jets as loarabia pointed out.

Private jets fly empty all the time. This would be additional revenue for the owner/operators of the private jets. Notice that most of the flights are one way. That is because the jet is flying empty to pick up the real passengers, who pay, essentially, for the jet to come get them and take them where they are going.

The real problem is what happens when wealthy people who fly private realize that poor schmucks are flying on their dime.
