Yes for now I thought it would be better to not show anything than a poor UI, and also the performance is not great on mobile right now. This is something I would like to improve for sure. Maybe a simplified version with limited UI?

Thanks a lot for the feedbacks! I spent quite a lot of time on this yes, though I was already quite familiar with 3d rendering and astronomical computation so it wasn't that hard. In fact the most difficult part was probably to learn WebGPU that I never used before.

For the issues:

1. Yes there are some bugs currently with the temporal anti aliasing. I was a bit aggressive on the effect because without it the Milky Way doesn't look good. I'll try to fix that (ideally it should adjust to the the velocity field).

2. All the time controls is still pretty much untested, I'll see if I can fix that.

3. I'd like to add more scale hints, but it's hard without cluttering the view. I'll see what I can do.

4. Yes at the moment there is only one black hole (sgr A*), I'll add more as soon as I can.

As for how this will evolve, I am not sure yet. I have a basic mobile version prototype working on iOS, so I thought this could turn into a mobile app at some point. No plan for an actual heavy PC app at the moment.

Yes mostly. The comets and satellites data is updated twice a day.

Hello, I am the creator and maintainer of Stellarium Mobile. I have been working in my free time for about a year on this new project Galaxium, that is more about traveling in the universe rather than looking at the sky from Earth. It is still experimental, and at the moment I am not sure what it will become. Feedback is welcome.

New comment by guillaumec in "Child prodigies rarely become elite performers"

At least for chess the article mentions that they considered the top 10 players in children and senior categories. This would indicate that prodigy chess players are millions of time more likely to become elite compared to the general population.

New comment by guillaumec in "Why not just do simple C++ RAII in C?"

guillaumec — Thu, 23 May 2024 07:05:04 +0000

I notice more and more pushes to 'improve' C and turn it into something it should not become. I feel like the C++ community gave up on C++ because of the growing complexity and so turned to C with the hope of adding to it the good parts of C++ without the ugliness. But this is of course hopeless: every added feature will create new issues that will be solved with new features until the language becomes too complex for anyone to fully understand.

I often wondered if Patrick uses unnecessarily convoluted sentences, or if he is simply careful about using the proper terminology, and my English is just not good enough to follow him like a native speaker would.

I wrote this in go and it made the front hackernews page at the time:

This was my first time using go and I found the language very handy for this kind of projects.

My original tweet had a typo (their -> there) :(

I deleted it and reposted it without the mistake. Sorry for this duplicate.

Yes, since I got too many requests from HN, I had to enable the CDN. I didn't realize it would cache both html and terminal request together. I tried setting "Vary: User-Agent" but it didn't work. You can add: "?term=true" to make it work in terminal for now.

You are probably right. I should also probably add a link to a 'true' plain text version that returns a pure txt.

Not at the moment, this was a week end project, and the code is quite horrible. But yes I should probably put it online and get advise.

Actually it also supports a black and white mode using only utf8 characters. I haven't exposed it yet though.
