I wish it was code-switching but the true may be that my english wasn't very good.
I learn yesterday that a French spy DGSE (French NSA) was spotted by the Canadian after exactly this kind of english errors (and other hints like the use of "octet" instead of "byte" and compiled with french local).
I find it fascinating how you slam words together - who cares about "correct"? Is there really a correct way to program in C++, in both French and a nod to English? In the end if it compiles and works - who cares!
Viva la Franglais++
However, I am aware that for some people, it can be annoying when someone else (me in this case) is seemingly lazy or just plain wrong when deploying words.
I used to be somewhat unkind about grammatical errors but let's face it: grammar is what the majority of people say it is and not what is pinned down in a book half-read and quarter-remembered from years ago.
A bit is perhaps the smallest addressable unit of storage (says my light switch) A byte manages to convey 256 different states and I would need eight light switches to store them.
The definition of byte is not a matter of grammar, and here on a forum centered about computing technology and business the distinction that matters not to you matters to many - CHAR_BIT is still part of current standards in important languages and hardware w/out 8-bit bytes is still in current use.
It's "vive", not "viva", in French, and "français" and "anglais" are both masculine, so "franglais" is masculine as well (so it would use "le" as an article).
You'll probably be more likely to hear "viva los Frenchies" from Brits confusing Spanish with French. To us Germanics, you Romantics sound all the same ... or something 8)
