complexworld | 11 months ago | on: What Your Sleep Tracker Gets Wrong About Sleep

This would be a godsend to if it works in a non-clinical setting!

I always wake up after 3-5 hours of sleep, and I usually can't get back to sleep during the night. According to Fitbit sleep monitoring even in those few hours, I don't get much deep sleep. Needless to say I am very fatigued during the day. If it wasn't for sleep medication I would be a complete wreck.

Getting the footnotes right is going to be really tricky. Sometimes I couldn't even read the superscript numbering on the original scans. And that was after zooming in to the max.

Reliably identifying the superscript locations should be enough since they are in the same order as the footnotes.

It's a little early for feature requests... but I would love to see an EPUB edition! It shouldn't be too hard once done with the hard work of getting the data structured structured.

My Dad was a university professor in mathematics. He loved his field! But the math department he worked in was taken over by someone who loved playing politics and maintaining power by playing favorites. My Dad refused to kiss the ring, and paid the price for that in his career advancement. He had tenure so it was never as bad as what happened to Marshal Brain.

Now we have n == 2, this could be a pattern. Of course it's a similar situation outside of academia too.

My problem is that I wake up in the middle of the night after 3-4 hours. Vaping one puff of indica cannabis puts me back to sleep until the morning. And even if I don't go back to sleep right away I'm feeling so good that I don't mind.

Apparently it's genetic. My genome has 100% correlation with genetic variants associated with insomnia.

I was interested in the Android positions mentioned above; but I didn't see them on the website. Have they been removed? Or should I apply to the Senior or Staff SW engineer positions?

When the vaccines were first tested and approved they reduced the risk of infection by 20 times!

Of course that no longer is true because the virus has mutated under selective pressure.

I hope we'll be better prepared next time. Something like a worldwide simultaneous vaccine campaign, instead of disorganized every country for themselves approach we've seen so far.

I work on a handheld ultrasound device that attached to a phone or a tablet. It is much easier to use than traditional ultrasound machines, because of the attention paid to the UX off the app, and the familiar smartphone UI.

That being said I will haven't learned how to use it in a meaningful way myself. Getting a good image, and then interpreting the 2d video stream requires training!

Making ultrasound easy enough for non specialists to use will require an AI that guides the user and interprets the images. I'm not convinced skipping FDA approval would be a good idea in this case.

I used the triple-foot pedal for about 1.5 years. I now have chronic discomfort in my left foot; the one I used for the foot pedal. Of course it might be a coincidence, or it could be a RSI from using the foot pedal.

complexworld | 4 years ago | on: Ask HN: Effects of Covid Vaccination on R0?

Yes I agree with you. I wish I could find a study that clearly shows that unvaccinated people are more likely to transmit the disease than vaccinated people.

There are studies, but the ones I have found compare only people are infected. And when you have COVID you're contagious, vaccinated or not. This is then used as a basis for claiming: "See vaccinated are just as, or even more, contagious as unvaccinated!". That's what I'm trying to disprove.

Example of what I have found: https://www.thelancet.com/journals/laninf/article/PIIS1473-3...

The person I'm talking with is young, healthy, and believes he is at very low risk of a serious case of COVID.

For society in general, the crux of his argument comes down to:

"Unvaccinated people are just as contagious as vaccinated, so why should I get vaccinated?"

I'm finding it surprisingly difficult to find unassailable evidence that vaccinated people are less likely to pass the virus on to someone else.
