Re: Fixing the wrong problem
Piping into less is super, if you are going to read it on screen.
Less so if it is to be piped on into something else - sed or wc eg

Short-sighted people mostly know that looking through a pinhole brings more distant objects into focus. In eye examination that's a way to distinguish refractive errors from other losses of resolution (bearing in mind that some people cant read even if they hadn't left their spe tacles behind)
Pinhole cameras are famously in focus at all distances,
Camera (etc) lenses begin to lose definition due to diffraction through an aperture when the aperture gets more comparable to the wavelength of the light.
Hence Ansel Adams at all could call their group f60 with their 10*8 cameras (which use long focal lenses) and I have to be wary toward f/22 with a 35mm camera.
The good eye sees sharper with a small pupil.
Bad eyes, with central cataract, less so, and all eyes need light.
It is easier to launch a projectile from the Earth's surface to any other point on the surface than to put one in orbit.
Maintenance over what is expected to be a long period is easier in the surface.
Deorbiting to a specified point from orbit is both harder and slower than a single trajectory from thd ground.
Keeping a satellite weapon safe from interference us non-trivial.
No, the point of orbiting a satellite is that it demonstrates the ability to hit anywhere on the surface (mass and orbit have some subtleties there) and that it allows observation of geavirstionzl variations along trajectories.
Cape at Warwick made ventilsyirs.
You might be surprised to hear that electronics, and even electricity, are not necessary components.
The Mamley is an old design, not ideal for ICU, which uses the incoming gas at 4 Atmospheres to blow a bellows with a brick on top, when thevadjustanle hook pulls the outlet valve a breath is sent.
