python - WSGIScriptAlias does but WSGIScriptAliasMatch DOES NOT regard DirectoryIndex -

this a.conf in /etc/httpd/conf.d/ rather edit httpd.conf work a.conf namevirtualhost *:80 <virtualhost *:80> directoryindex 1 documentroot /a/b/ servername domain.tld wsgiscriptalias /1 /a/1.wsgi wsgiscriptalias /2 /a/2.wsgi </virtualhost> in example if go domain.tld via web.. wsgiscriptalias /1 /a/1.wsgi is automatically executed. but let's rid of wsgiscriptalias , use wsgiscriptaliasmatch instead. <virtualhost *:80> directoryindex 1 documentroot /a/b/ servername domain.tld wsgiscriptaliasmatch ^/(.*) /a/$1.wsgi </virtualhost> now.. when go domain.tld via web.. not see 1.wsgi instead default apache welcome page. so looks like.. wsgiscriptaliasmatch ^/(.*) /a/$1.wsgi is not paying attention directoryindex 1 in other words via web domain.tld/1 works domain.tld not.. what causing ? how wsgiscriptalias /1 /a/1.wsgi can interpret domain.tld domain.tld/1 given directoryindex 1 but.. wsgiscriptaliasmatch ^/(.*) /a/$1.wsgi

c - Bitwise operators: Printing the numbers 1 to 100 using bit manipulation -

i believe possible generate numbers 1 100 using bitwise operations or bit manipulation, rather traditional increment instruction. what possible methods of doing this? i believe there couple of ways achieve it. 1 of them use tilde operator ~x bitwise complement , equal -(x+1) int increase(int x){ return (-(~x)); } so increment value above-mentioned function , print it. apart own answer, found way make addition bitwise operators . int add(int x, int y) { if (y == 0) return x; else return add( x ^ y, (x & y) << 1); } just substitute y 1 , way of incrementing value.

javascript - Mongoose - What does the exec function do? -

i came across piece of mongoose code included query findone , exec() function. ive never seen method in javascript before? exactly? basically when using mongoose, documents can retrieved using helpers. every model method accepts query conditions can executed means of callback or exec method. callback : user.findone({ name: 'daniel' }, function (err, user) { // }); exec : user .findone({ name: 'daniel' }) .exec(function (err, user) { // }); therefore when don't pass callback can build query , execute it. you can find additional info in mongoose docs . update something note when using promises in combination mongoose async operations mongoose queries not promises. queries return thenable , if need real promise should use exec method. more information can found here . during update noticed didn't explicitly answer question: ive never seen method in javascript before? exactly? well it's not native j
