I had this argument with people working on VR headsets, where a physical parameter was designed to cover the 5th to 95th percentile. I had to point out that flat-out excluding 10% of the population is a pretty crappy starting point...

In most amateur imaging you can trade time for quality. By stacking enough images, satellite trails get averaged out of the final image. Very high end amateurs get pissy about it because they paid a lot of money for high end equipment to mi

You’d be amazed what even a small smart telescope can see even in Bortle 9 urban skies. I have one of the mentioned SeeStar smart telescopes, and have been quite successful in taking photos of both galaxies and nebulas from the rooftop of m

iTelescope does exactly what you’re outlining. There used to be a few others but I think they have mostly died out. I assume the economics don’t really work out.

Really? I read the same sentence (as an American) and immediately thought that they must be referring to British English. Certainly nobody says brilliant as an affirmation here. And "no problem" and "not bad" are both co

As far as I know Apple will still sell you individual tracks (DRM free, I think?), though it’s a bit hidden.

This is a pretty standard topic, and not really a compiler optimization. It's usually called a unity build. [0] https://en.wikipedia.org/wiki/Unity_build

All of the major C/C++ compilers are deterministic functions of their inputs. This is a pretty major property, and any regression is rapidly detected and fixed. Optimization "timeouts" aren't done in wall time, but in so

The textual IR is not backwards compatible, but the bitcode format has been best-effort auto-upgradeable for as long as I've been involved (2006). The policy is documented here: https://llvm.org/docs/DeveloperPolic

If you know that you need to offload matmuls, then building matmul hardware is more area efficient than adding an entire extra CPU. Various intermediate points exist along that spectrum, e.g. Cell's SPUs.

You can, but what does it help? Modern OSes are architected assuming an always-online, the-world-ends threat model. Thus causes them to be heavily locked down, eliminating a lot of the customizability and hackability that older systems had.

I miss having a world where the threat model of having your computer compromised wasn't "your entire life ends". Where a device wasn't assumed to be online all the time, and where every device didn't contain the key

My favorite memory of Halted is finding an Atari 2600 in a box with an Atari company store sticker on the box, and someone’s DIY controllers with it.
