Code 127 is officially named "delete" but the Teletype label was "rubout". Since the original standard did not give detailed interpretation for most control codes, interpretations of this code varied. The original Teletype meaning, and the intent of the standard, was to make it an ignored character, the same as NUL (all zeroes). This was useful specifically for paper tape, because punching the all-ones bit pattern on top of an existing mark would obliterate it. Tapes designed to be "hand edited" could even be produced with spaces of extra NULs (blank tape) so that a block of characters could be "rubbed out" and then replacements put into the empty space.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why was standard code useful for paper tape?
Ah, so.. unanswerable

The uses of copper in art were not limited to currency: it was used by Renaissance sculptors, in photographic technology known as the daguerreotype, and the Statue of Liberty. Copper plating and copper sheathing for ships' hulls was widespread; the ships of Christopher Columbus were among the earliest to have this feature. The Norddeutsche Affinerie in Hamburg was the first modern electroplating plant starting its production in 1876. The German scientist Gottfried Osann invented powder metallurgy in 1830 while determining the metal's atomic mass; around then it was discovered that the amount and type of alloying element (e.g., tin) to copper would affect bell tones. Flash smelting was developed by Outokumpu in Finland and first applied at Harjavalta in 1949; the energy-efficient process accounts for 50% of the world's primary copper production.

When it comes to civil and criminal cases, the Bundesgerichtshof is at the top of the hierarchy of courts. The other branches of the German judicial system each have their own appellate systems, each topped by a high court; these are the Bundessozialgericht for matters of social security, the Bundesarbeitsgericht for employment and labour, the Bundesfinanzhof for taxation and financial issues, and the Bundesverwaltungsgericht for administrative law. The so-called Gemeinsamer Senat der Obersten Gerichtshöfe (Joint Senate of the Supreme Courts) is not a supreme court in itself, but an ad-hoc body that is convened in only when one supreme court intends to diverge from another supreme court's legal opinion or when a certain case exceeds the authority of one court. As the courts have well-defined areas of responsibility, situations like these are rather rare and so, the Joint Senate gathers very infrequently, and only to consider matters which are mostly definitory.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What court has supremacy for matters of social security?
Ah, so..
Bundessozialgericht
