In my opinion, the "quirks & different ways of doing things" are a key part of knowing a language and are essential for building large or complicated systems. For example, while I may be able to look in the documentation to find the library classes and methods to open a file and write to it, Java/C#/C++ have quite different idioms and constructs to ensure that handles are properly closed in the presence of exceptions. While it would be possible for me to very easily write something hacky that worked most of the time in Java, there is a good chance I will miss some quirks of the language and runtime which either cause things to break or could have been exploited to make the code smaller and more readable.
I agree that a lot of the hard work goes into the learning the first language most of which can be reused for subsequent languages, but at the same time I would feel uncomfortable putting myself forwards as a Java programmer despite good C++ and C# knowledge and experience.
Masturbation is Art too
The proposal appears to be usual blend of new modulation techniques, all optical switching and the usual "green" nonsense which is required to get anything approved these days.
ISBN check codes are designed to catch common errors back when hand entry was common -
a run of two digits in the wrong place (eg 556 instead of 566)
a mistyped digit
two digits swapped around by one place
The UPC code does not support the latter at the expense of only requiring the check symbol to be one of 10 regardless of the number of digits in the code. The ISBN algorithm requires n+1 where n is the number of data digits. Whether this is required nowadays given that very few ISBNs are entered by hand is another issue.
Except that electrons travel a fuckton slower than the speed of light through a wire. 66% through standard coaxial
Electrons travel a lot slower than that - although you are correct that that is the wave propagation speed in coax which is what really matters.
It's still faster than wave propagation in an optical fibre though.
It is still used in a lot of theatre installations in the UK. It means the only fuse/breaker to blow/trip is in the dimming rack not 20 feet up on an inaccessible lighting bar as might happen with BS1363. Also makes chained extensions far easier to deal with.
