I write code for Earth science missions, but maybe not for long. I also used to work for the Intelligence Community.

| But apparently this was a black swan.

What is your definition of black swan? This paper is from 2022 and scientists have been warning about climate change for decades. It's not like this possibility wasn't anticipated. It seems likely we'll see more glacial events as the atmosphere warms.

I can't tell if you're parodying HN here. This is from someone's blog and is a personal reflection on his most important work of the past 10 years. Do you expect everyone to be an historian?

I did similar a few years back, but for Mars DEMs, also in PDS format. At first I despised it, but yes, there is a certain pragmatism to the format. And, yeah, the best way to figure out what was going on was to just look at the files themselves.

The thing that most annoyed me at the time was there wasn't a good open source JPEG2000 decoder I could use to slice up the imagery to go along with the DEMs. But that must have changed by now...

Having read about historical radio astronomy and practiced signals analysis, I think they were a little more sophisticated than that. The recording in this format was made for easy perusal by a human, say, the next morning. I think that was the case with this signal. No doubt they wanted to revisit that spot in the sky looking at intensity, frequency shifting (Doppler), bandwidth, modulation, etc. But they never saw it again.

Historical point of interest: the Big Ear telescope that recorded this was bulldozed to make way for a golf course.

I started here: http://reactfordesigners.com/labs/reactjs-introduction-for-p... (h/t tptacek).

And then I found the egghead.io videos particularly helpful. Nice bite-sized chunks, very focused: https://egghead.io/technologies/react

There are a number of free lessons. I found them useful enough to pay for a subscription. YMMV.

I do. The one I'm familiar with has large garden areas, trees for climbing/wandering around, uncultivated wilderness areas, etc. It's not a vast tract of land, but enough that it seems huge to a small person. Indoor time focuses on exploration of provocations set up by teachers, telling stories, singing, role-playing, etc.

Depends on what you mean by "school" (NB the quotes in the parent comment). There is a huge variance in options for working parents of a 2-3 year old. From cramped cinder block day care -- aka The Cacophonous Petri Dish; to private nanny; to "forest schools" where kids spend as much time as possible outside digging in the dirt, climbing tree stumps, and learning how to devise and engage in large projects together (yes, a group of 2.5 year olds is capable of this).

I don't think the parent comment was talking about toddler MIT.

I might be wrong, but I believe the THREDDS server the article points to (by way of https://cds.nccs.nasa.gov/nex-gddp/) supports OPeNDAP, which means you can pull subsets of the data, i.e. if you've got a 40GB file, you could slice a tiny portion of that off for downloading.

I knew about Guided Access, but I forgot it allowed you to disable specific regions of the screen. Thanks for the reminder.

Nice. I'm going to put this in front of our resident toddler tonight.

Bit of feedback:

* I would have been willing to put down a couple of bucks up front just to try it out, even without the extras available in-app.

* How about "toddler resistant" mode that disables the sharing, feedback, social buttons? Kids tend to touch and drag all over the place, often seemingly at random. The less they end up in a strange place and are able to figure out the core interface, the better.

This comment explains why I saw so many bumper cushions. And it also explains why I never want to drive in a car again.
