Would be a better title

#12If you want to avoid opening Twitter (now known as X), here is the link to the paper: https://arxiv.org/pdf/1502.03808
TLDR “A typical IMAX image has 23 million pixels, and for Interstellar we had to generate many thousand images, so DNGR had to be very efficient. It has 40,000 lines of C++ code and runs across Double Negative’s Linux-based render-farm. Depending on the degree of gravitational lensing in an image, it typically takes from 30 minutes to several hours running on 10 CPU cores to create a single IMAX image. Our London render-farm comprises 1633 Dell-M620 blade servers; each blade has two 10-core E5-2680 Intel Xeon CPUs with 156GB RAM. During production of Interstellar, several hundred of these were typically being used by our DNGR code.“

#13It is a pity they didn't spend comparable effort on the story. I thought it was a really disappointing film, especially after they banged on so much about how good the physics in it was (apart from the black hole rendering, it wasn't).
Did we watch the same movie? They got bunch of physics stuff right, like the water planet, the relative aging due to being near the massive black hole etc. Only thing that wasn't "correct" was the wormhole and especially the tesseract, but that was some creative writing which allowed for a nice twist. I enjoyed it, a nice scifi.
Their starship was bullshit. On earth they needed a big Saturn 5 like rocket to bring it into space and later they fly into orbit like it's nothing.
If the planets they visited had much lower gravity then earth this may be possible, but this wasn't noticeable or talked about. And even on Mars you need much more fuel to get into orbit than could be stored in their tiny ship.

#16There was a pretty good talk[1] on this at SIGGRAPH 2015. Speakers included later Nobel prize winner Kip Thorne.
I tried to find any recordings but had no luck. (Presumably it's on the conference DVD)

#17I wonder if people who wrote that code also consider their job boring and uninspiring
They work in VFX, so their primary concerns are getting enough sleep and being able to pay rent.

Repetitively translating existing formulas to code is not that satisfying.

The whole premise is bogus and explained by Michael Caine in only a few sentences.
We have a plague on Earth and doing an interstellar travel is the solution?
I was very disappointed. I’m OK with a few plot holes, but this is so fundamental to the story that the movie can’t stand on its own.

Is Intersetllar the movie where Matthew McConaughey turned into a bookcase?
