javascript - Is there any way of making this function more efficient in a standard browser? -

-

while profiling web app in chrome found following function function taking large percentage of total runtime app (which reasonable considering how used - maybe 1000 times each page load). therefore wonder if has suggestions of how improved increase performance?

function getdate(datestring) {     re = datestring.split(/\-|\s/);     return new date(re.slice(0, 3).join('/') + ' ' + re[3]); }

this function given string in form: "yyyy-mm-dd hh:mm:ss", example: "2014-06-06 23:45:00", , returns javascript date.

i using jquery option.

not using many array operations, , not using global re variable, should help:

function getdate(datestring) {     return new date(datestring.replace(/-/g, "/")); }

however, notice yyyy-mm-dd hh:mm:ss valid date format parsed date constructor directly (ok, maybe not in older ies), in standard browser work well:

function getdate(datestring) {     return new date(datestring); }

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...
