types - Confusion due to Swift lacking implicit conversion of CGFloat -

-

trying arithmetic in function returns `cgfloat, error:

couldn't find overload '/' accepts supplied arguments

func kdccontroldegreestoradians(x : cgfloat) -> cgfloat {       return (m_pi * (x) / 180.0) // error here.  }

has else seen type of issue?

this problem double float conversion.

on 64-bit machine, cgfloat defined double , compile without problems because m_pi , x both doubles.

on 32-bit machine, cgfloat float m_pi still double. unfortunately, there no implicit casts in swift, have cast explicitly:

return (cgfloat(m_pi) * (x) / 180.0)

the type 180.0 literal inferred.

in swift 3

m_pi deprecated, use cgfloat.pi instead:

return (x * .pi / 180.0)

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
