Comment: File System (Score 1) 226 226

There were two things I liked about the VAX/VMS filesystem that I would port over. The first is version numbering. A file would start as filename.1 and the number would increment with each edit/save cycle.

The second thing would be logicals and overlayed directories. They worked like a stack of transparencies like the human anatomy entry in an encyclopedia. The base layer would be a read only version of the operating system. Above that would be a writable layer. Above that, for development users, would be test versions of new OS elements. Regular users wouldn't see these layers. Above that would be applications (read only) with a writeable layer above it.

The purpose of the writeable layer over the read only layer is to trap attempts to overwrite system files.

Comment: Mayday! Mayday! (Score 1) 117 117

I've been binge-watching Mayday (a.k.a. Air Crash Investigations), and I have not seen a single episode where bug splatter on the wings brought down a plane. There was one episode where a spider built a nest in the pitot tube, but nothing with the wings. They would be far better off developing anti-ice coating. Ice brings down planes on a regular basis.

Maybe, but I suspect maybe not. The electromagnetic spectrum (which includes light frequencies) has particular characteristics that do not change much with increases in frequencies, closed system or not.

Granted, but optical signals are not generated by a coil of wire and interleaved metal plates. You can't just tweak a capacitor to adjust the frequency of a laser.

No private citizen NEEDS a gun either; or a car, or a computer, or porno magazines. That doesn't mean we can't have them.

The reality of the situation is that the persons taking video of the fire with their fancy flying cameras were probably unaware that they were interfering with the fire-fighting effort.

Most public domain software is free, at least at first glance.
