<p>Many of those big bells in other cultures are on fixed mountings (in a carillon, for instance). The idea of mounting the bell on a rotating wheel - which imposes limits on what music can be played due to the rotational inertia of the wheel, therefore leading to a unique style of composition - is distinctively English.</p>

<p>More likely a hall effect sensor, which is solid state and a lot smaller. And yes, older MacBooks had something like that, as evidenced by the fact you could put them to sleep by holding a magnet in the right place (just to the left of the trackpad IIRC in the models I'm familiar with)</p>

<p>> My family had a small B&W CRT that fascinated me with its image quality, in that it always reminded me more of a b&w photo than color CRTs reminded me of color photos.<p>The problem of a finite dot pitch interfering with image quality, especially on small displays where the dots were necessarily larger relative to the image size, is what motivated Tektronix to develop field-sequential color CRTs which they used in their digital oscilloscopes in the 80s and 90s. JVC also used the technology in some professional broadcast video monitors. Basically it was a B&W CRT with a changeable (liquid crystal) color filter in front of it. The R, G, and B channels would be shown one after another with the corresponding filter activated, in a similar manner to a color wheel DLP projector.</p>

<p>It was based on FreeRTOS, but FreeRTOS at the time was extremely bare bones and only provided a preemptive scheduler, task management, and synchronization primitives. Everything else (memory management, I/O, ...) had to come either from whatever libc implementation was in use, or be built from scratch.</p>

<p>Flash as an animation tool and applet platform was already on the downswing when the iPhone happened, though.<p>The consumer demand for Flash on mobile seemed to be mostly about video streaming, because at the time Flash was experiencing sort of a second life as the least-bad way to do streaming video on the web. In that context Apple's point of view of "as an industry let's finally fix browser-native video streaming, rather than being stuck with Flash forever" seems pretty reasonable.</p>

<p>If you apply a constant current to a capacitor, the voltage across the capacitor will increase linearly as the capacitor stores energy in the electric field.<p>If you apply a constant voltage to an inductor, the current through the inductor will increase linearly as the inductor stores energy in the magnetic field.<p>Perhaps part of why the intuition can break down is that in real life, inductors tend to be much "leakier" energy storage devices than capacitors. If you store some energy in an inductor and then change the voltage across it to zero (practically: short its terminals together), in theory a perfect inductor will maintain a constant current forever and the energy stored does not change. In practice inductors (with an exception for things like superconducting magnets) are made from wire that has a resistance, and so the current in a real shorted inductor will eventually decay to zero. This means that in practical terms inductors are mostly only useful for short term energy storage. On the other hand, real-life insulating materials (like air, vacuum, or Teflon) can can be pretty close to perfect insulators allowing real capacitors to store energy more or less indefinitely... certainly on timescales of years.</p>

<p>The meme started as eating <i>paste</i>, back when that meant wheatpaste (made from flour and water).
