jonlucc commented on California invests in battery energy storage, leaving rolling blackouts behind latimes.com/environment/s... · Posted by u/JumpCrisscross

Any time you have hundreds of megawatts of energy stored in a small area there is risk. This includes steam boilers, nuclear reactors, batteries, dams, etc. No getting away from that. Not saying that some battery chemistry might not be easier to manage than others.

This is an inherent problem with storing power. There's a massive battery in Missouri known as the Taum Sauk hydroelectric dam. During the night, they pump water up the hill into the upper reservoir, and in the day, they let the water run downhill through turbines to generate electricity. In 2005, the wall of the upper reservoir failed.

This is great data visualization of interesting data! I'm curious about the last graph; there seems to be something making some of the longest flights take more time/nm. Is that real or an artifact, and is there an explanation for the tail?

I can remember Trump trying to take credit for funding the vaccine efforts, and getting nothing but negativity from his crowd.

Unfortunately, it predates both presidents. It's just kept creeping upward in popularity, along with a lot of other conspiracy theories.

This is true, but leading up to the vaccine, he embraced every stupid conspiracy, related to COVID and before. Remember the bleach and sunshine press conference? A better leader who actually tried to understand the science at a basic level when they have their choice of incredible experts would have been better at communicating to the public from the beginning. He let the horse out of the barn, and that's famously hard to undo.

Based on the title alone, I thought this might be a skateboard that moved on millipede style legs, rather than wheels.

Also of note because of recent political choices, these are humanized mice, meaning they're transgenic. They have a human ACE2 gene instead of the mouse ACE2 gene, which makes the human version of the enzyme that the COVID virus uses to enter cells. This isn't my exact field, so I'm not positive, but I remember hearing that all of the COVID mouse models require transgenic mice.

The vast majority of people couldn't care less about open source

jonlucc · 10 months ago

If you're paying $200/month for something I can do with open source software and $10/month of compute, why wouldn't I offer you the service for $100/month? And then someone offer it for $50?

Not everyone has to know about, understand, or use open source solutions for it to open the field.

Tangential, I want to build a camera based fish feeder, is there any hardware that can shake fish food pellets and can I use my python knowledge directly?

jonlucc · a year ago

I think you're looking for CircuitPython, which is available on a variety of small boards [0]. Based on my, admittedly, very limited experience, I would strongly consider the Feather line of products from Adafruit [1]; they're compatible with each other, most have CircuitPython support, and they mostly have STEMMA QT ports for simple connections to I2C-based peripherals.

Is this accurate in all cases? Isn't Jenny Nicholson one of the bigger YouTubers, with videos coming out maybe once or twice a year?

jonlucc · a year ago

I know it's been a while, but I think Jenny Nicholson grew her audience with shorter content. I recall "script meeting" videos about a lot of movies as they came out, and those were shorter and more frequent. Now that she has a dedicated audience, she doesn't rely as much on the algorithm to surface her.

They have the NFL next month on Christmas day. So that'll be a big streaming session but I think it'll be nothing compared to this. Even Twitter was having problems handling the live pirate streams there.

> Even Twitter was having problems

Is that a surprise? They're not who I would think of first as a gold standard for high viewership live streams.

T1D here who has been using Dexcom G6 for many years now. Interesting to see the differences between Stelo and G7 which are built on the same platform.

Curious if anything is driving the increase in wear time other than battery life savings from reporting back fewer readings.

  CGM:                   G7 / Stelo
  Wear time:             10 / 15 days
  Time between readings:  5 / 15 minutes

jonlucc · 2 years ago

I'm not sure how much I can say; I don't work for a CGM company, but my company is very interested in diabetes. There are non-device reasons you can't use a CGM indefinitely. The site becomes less reliable over time, and it varies from peron to person. I'm not sure if the Stelo has addressed any of those, or if the G7 was overly cautious, or something else, but there are biological things happening at the site that affect the time too.
