Beautifully done! Simple, elegant, and how in the unholy hell do I not know how to spell "photo"??

I anticipate the NY Times will buy you out and I am very jealous

Global warming may bring us more rain overall, but the current high pressure system (expected to end tonight?) has kept rain away from us for 2 months now, which wasn't helping anything.

The article doesn't mention that 700 full-time park workers were cut in Eric Adams' budget. 50 of those park workers were forestry specialists, who did things such as removing sick/dead trees, and clearing the sort of brush/debris that is easily ignitable.

We see this over and over again: whatever money you "save" by delaying or skipping maintenance, you end up having to spend when something actually breaks.

D'oh! Looks like there's still room for improvement :-/
I had a 10 year old CPAP machine, Respironics SystemOne. I kept telling myself that I needed a new one and I should go and get a new one, but I never did because this one was plodding along "fine". Looks like I dodged a bullet by not getting an updated one, because they probably would've given me one of those Dreamstations!

Did a sleep apnea test last year, it came back negative, which was weird because I can't sleep right without a CPAP.

I redid the test a few months ago, which also came back negative, so I asked to look at the full results, not just the summary. The analysis said I didn't have sleep apnea because I was ONLY WAKING UP 10 TIMES AN HOUR.

I insisted on a new machine, they gave me a ResMed AirSense 11 (autopap) and I've been sleeping like a baby for the last 2 weeks. The technology has improved so much:

* No more SD card!

* Results show up in the phone app in < 24 hours. (Machine modem -> cell network -> provider -> app instead of machine -> app, which I think explains the delay)

* The device detects when you've put the mask on and turns itself on automatically.

* The masks themselves are so much better, so easy to put on and remove.

* The app shows if air is leaking so no more endless fiddling with the mask to ensure a good fit.

This is one of those cases where it really does feel like we're living in the future.

It is likely related to the blackout due to the reddit CEO being dishonest about the upcoming API pricing changes. You can read more here:

Supposedly this is not the case: https://www.hellgatenyc.com/the-death-of-nyc-payphones-lies/

If you live in the NYC area, I guess you could hop on down and verify this yourself.

Re:Ask HN: Recommend a maths book for a teenager? on Friday July 03, 2020 @04:41PM (#23727375)
I suggest Infinite Powers by Steven Strogatz. It doesn't matter if they already took a calculus course, I guarantee it's a much better way to make them appreciate the the subject than any textbook. And if they don't know calculus yet, that just makes it even better!

If I'd read this book as a teenager, maybe I would've passed Calc I on my first try as opposed to my third. With a C-.
