Android and PhoneGap -

-

i had urge learn android build apps , games, looked fun language if had prior knowledge java. found out there other frameworks convert codes native features apps phonegap , there unity helps in cross-platform game development uses javascript, c# , boo. question if frameworks these exist why need learn native languages? difference make?

using native languages

advantages

the native applications allow full use of device capabilities might missing in other third party apis.
easier performance application when programming using native sdks.

disadvantages

requires learning different languages development on different platforms.
the code base developed 1 platform cannot adapted platform.

using frameworks phonegap

developers can build applications using html/css/js, including javascript classes give access device hardware , other ios api featurs contacts, filesystem, camera, microphone, gps, etc. final application wrapped within platform native 'web view' browser object, , becomes stand-alone web application ability access device- specific features.

advantages

one can use plain old javascript or other libraries jquery, prototype, sencha touch, mootools, etc handle interaction.
allows development several platforms @ once, e.g. android, ios, windows etc.

disadvantages

the applications web applications inside web-view. browser performance doesn't come close native application component performance.
not device apis available applications.

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()

-
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...
