comment What is a “pipe” and how can it be “broken”?
Actually, it's only "broken" if the reader closes it. If the writer closes it (as cat obviously will as soon as it's finished), the reader will just see a normal end-of-file.

comment What is the origin of K = 1024?
The 1961 entry there is interesting, in that it mentions "65k" - being the first order of magnitude which can show a clear difference between "k=1024" and "k=1000, rounded", it comes down clearly for the latter. In 1964, on the other hand, everyone is using the binary meanings.

comment Can zipping a file break it?
The term "checksum" has clearly become somewhat broader in meaning than its original definition if people can [and they do] call the results of cryptographic hash functions "checksums".

comment How can I lock a folder so that it CANNOT be erased?
On the site you linked, the /d flag is documented as only taking a user argument, not a user:perm argument. If I try the same with cacls, which is documented the same way on win7, it claims to not be able to understand the username with a : in it.

Does xcacls actually provide a way to add a denial?
