Make emacs automatically open binary files in hexl-mode
How can I make emacs automatically open binary files in hexl-mode? It's probably sufficient to define "binary" as "contains a null byte" (I suppose https://github.com/audreyr/binaryornot could be used if that ends up being an insufficient…

How can I convert hexidecimal values to base 10 in hexl-mode?
A nice feature of viewing binary files with hexl-mode is it displays the equivalent ASCII values to the right of your hexidecimal lines.
Is there a way to make hexl-mode treat hex values as floats, doubles, or some other format instead of ASCII? If…

Why are there 2 exact same Emacs Binaries in the bin folder?
In the Windows Binary release, if you look at the bin folder, you can see a binary file Emacs.exe and another one Emacs25.1.exe, these 2 files are exactly the same. And it seems that deleting Emacs25.1.exe doesn't affect it in anyway if you use…

Detect whether a file is "binary" from elisp
I am wondering whether current versions of Emacs have any built in mechanism for guessing whether a file (that my elisp code is about to load, or perhaps has just loaded, into a buffer) is 'binary' rather than 'text'.

nhexl-mode shows bytes 80-ff with 6-digit hex 3fff80–3fffff

I observed this on Emacs 23.2 and 24.4 started with emacs -Q. On Emacs 22.2, it works fine.
