This issue is that certain tasks require administrator privilege on
Windows and it's much more friendly to check the current user's
privileges and inform the user that he or she needs to elevate to
admin than simply fall over. :)

Sadly before Windows 7 most users are on their machine as admins by
default (which is, truly, a large part of the reason that Windows was
such a fruitful hunting ground for people who liked to spread
trojans).  A lot of users still have admin privileges by default but a
few are smart enough to practice least-privilege.

Thanks Doug--that's sort of what I was hoping for.  Like you my issue
would be figuring out which API's to call.

Re: [Factor-talk] restricting ratio literals

2016-10-25 Thread Jon Harper 
I would say no prefix at all for ratios, only base 10.
Also do people in the US consider 1+13/2 a number? Or is it really only
written as 7+1/2?

I think the number literals should only express what people consider as
numbers. They should not replace arbitrary mathematical operations (like
your 60/2.5 example) which are folded by the compiler anyway.

What do you think?

Le 25 oct. 2016 02:22, "John Benediktsson"  a écrit :

Those examples do look ugly -- maybe base 10 ratios only is not a bad idea.


But would it support the 0d prefix?  e.g. ``0d1+1/3``?
