We're saying the same thing -- one radioastron satellite isn't enough, you'd need a constellation of them.

> How about putting our astronomy experiments into space as well? There'd be no light / em pollution there, as well as no atmospheric interference etc. One would need to put the telescope…
comment
> In space there are no limits, see Radioastron for example, and that was decades ago. Radioastron required cross-correlating the signal with ground-based radio teleacopes in order to do science. T…

There's at least two issues with this line of thinking: 1. many astronomical observations are long integrations (many minutes of open shutter) and you often cannot read out the pixels during the …

Can you elaborate on how this is doable (in, say, Racket) and what tooling is needed? I'm afraid your reply doesn't add much information beyond the same assertion that I quoted that was in t…

That could very well be it. I guess I had gotten my hopes up, seeing the statement in a piece that purported to be specifically about Scheme .

> You can pause, inspect objects, change values, and even redefine a broken function on the fly to test a fix in any environment (yes even in production, while running). I see this mentioned often,…

There is a mission concept for a far-infrared interferometer: https://asd.gsfc.nasa.gov/spice/ One would need to go to space for that of course.…

I thought the same thing too, when it was announced. But I suspect, in addition to the price, that not being able to buy a medium or long bed version also harmed fleet sales. The short bed being the o…

I was thinking about employee-facing tools, but I agree that TUIs present an even bigger challenge for casual users / customers.
comment
An interesting theme here in the comments (that I am sympathetic to) is "TUIs have steep learning curves but are fast/efficient for people with proficiency". I wonder if a small part of…

Oops, thanks. Too late to edit, unfortunately.

It could partly be that, but I've generally read that the default inks are not waterproof. I was curious about this so I just did a quick non-scientific perusal of one fountain pen enthusiast sho…
