I just ran into this today: https://github.com/gumyr/build123d - seems like an LLM should have no problem writing python code...

That is an awesome site. I had no idea it existed. Thanks.

Nice! I recently bought a Dwarf 3 smart telescope and immediately hit the same problem — figuring out what to look at and when. I ended up building my own solution that takes a different approach: https://astraview.app

I recently released https://astraview.app It's an astronomy app that lets you create custom horizon profiles for one or more locations and predicts what can be seen (galaxies, deep sky objects, planets etc) and when according to your specific views. It also has built in cloud forecasts and many other useful features for amateur astronomers

New comment by markcheno in "Ask HN: How plausible is it to continue becoming a lifelong programmer?"

markcheno — Thu, 22 Mar 2018 02:42:12 +0000

There is nothing keeping you from remaining a programmer as long as you are good at it. I am in my early 50's and have been programming since I was 13 years old, professionally since I was 18. I have studiously avoided management for my entire career and have survived several severe layoffs. Middle managers can be replaced far easier than a good programmer with extensive experience. You do need to be either an expert in an obscure field or be able to keep up with the latest technologies. I do both. I intend to retire as a programmer.

I wrote a small cli/library to pull tickers and historical quotes from various sources directly to csv or json. It still works with the new Yahoo format, but I wouldn't count on it sticking around. Also pulls bitcoin data from gdax.
