Leaded glass was a cost-cutting measure, used only for the back and sides of CRT. Leaded glass gradually turns brown under X-ray exposure, so the front screen used barium and strontium instead. There's no reason the whole CRT couldn&#x

As far as I know, all plasma screens use pulse width modulation to control the brightness of each subpixel. This produces even worse motion quality than a typical LCD; you get both sample-and-hold blur from the high persistence, and phantom

You do want to simulate it, because it's the only way to preserve the original motion quality of games designed around a fixed 60 fps frame rate without changing the gameplay or adding latency.

The ghosting on the original Game Boy did not blend pixel boundaries and did not affect static images. It looks nothing like a CRT and nothing like a zoetrope (which has sharp images and reasonably low sample-and-hold blur because of the st

Those are the SD CRTs the article talks about, not the VGA or SVGA CRTs used to play DOS games.

But in practice, VGA and SVGA CRTs always used RGB connections, so that's not relevant to games.

If you assume a SD CRT, as the article does, then yes, the display connection makes the most difference (although there are still differences between individual CRTs). But that does not cover all CRTs relevant to pixel art. If you display l

The article is about SD CRTs (480i for NTSC or 576i for PAL, or more commonly for games 240p/288p progressive scan using non-standard timing, often underscanned with pixels left unused in the borders). VGA MS-DOS games usually ran at 3

Those kind of cosmetic features actually do have a functional use because they let you distinguish virtual desktops at a glance. I'd like to be able to specify different window manager themes for each virtual desktop.

The argument became false as soon as we started reinforcement learning. Simple token-completion is arguably just simulating human behavior. Once you start training it on specific tasks you're training a level of single-minded goal-seek

Actual frequencies matter in bass-focused dance music. You want a root note around 40Hz to 60Hz, which is high enough that it's easily heard and reproduced, but not so high that it loses the tactile body-shaking effect.

Possibly. If I had some side-effect-free means to permanently prevent all sleep I'd take it without hesitation. But that's not relevant to the discussion, because it's not anything similar to what an LLM does. Your brain chan
