Works really well even on my old-ish smartphone (2014). WebGL is really interesting, too bad I still have yet to find the time to get a grasp of it. But blog posts like this are very inspiring!

Congratulations Fedora! Everyone is praising the GNOME (default) edition. Does anyone use the KDE spin? Also, how are Fedora version upgrades nowadays? I'm trying to decide between KDE neon and Fedora.

At least there's a simple equation [0] for the deflection of light rays caused by a black hole. If your background is a UV map (for example), then it should be easy to compute the distortion effect. rantonels (whose raytracer was the s

Thank you! A comparison between different integrators is in the plans. It would be certainly interesting to try e.g. velocity Verlet and some other symplectic integrators.

Thanks for the compliment and suggestion! The redshift would be interesting to do, I'll consider that.

My take on the accretion disk isn't very physically-based. It's really mostly meant as eye candy. However, the distortion (the form it takes) is physical and due to the Schwarzschild geometry. The physical explanation of an accret

That statement is indeed a bit vague. Let me elaborate: In the process of deriving the said equations, an equation for the radial coordinate of the photon was achieved. This was identified with a classical, Newtonian system of one particle

Maybe in the future, and in small resolution. Right now the renderer doesn't have any animation functionality, but this is definitely something I've been considering.

Hello HN! I thought I would share this little writeup on a project I'm quite proud of. The code can be found on GitHub [0]. This article is mostly about the implementation of the simulation in Haskell. I've also written another ar

Are you using neomake by any chance? I might switch from syntastic as neomake seems to support the linters I need (mainly eslint and hlint).

Done. Thanks for the reminder.

Funny how the X11 "Fixed" bitmap font [0] is chosen as the default font on my system. This appears to be caused by 'fixed' being set as a fallback font instead of 'monospace', which, on most systems, is an alia

There's a variant of lodash with auto-currying and better argument ordering: https://github.com/lodash/lodash-fp I haven't tried it, but it looks like it could basically replace Ramda (although I feel that Ra

I'm a physics sophomore, and I would be very glad to see more programming, especially FP, integrated to physics courses. During my studies, I've programmed some simulations related to the physics courses I've taken. My main p

First mass counting from which end? The masses are accelerated by each other as there are rigid rods between them. The lack of friction and the perfectly rigid coupling between the joints might be what makes it seem lacking reality. If we&#

Very nice simulation you've got there! I also did a triple pendulum in JS a while ago. Quite a lot more than 100 lines of code, though. The equations of motion alone take up lots and again lots of space. (Imagine typing them in! I don&
