i still don't quite understand why must keep index.php in public directory instead of in root directory. root/of/project public/ index.php .htacess (html, image, css, etc) then, write following in our virtual host file: documentroot /path/to/myapp/app/public <directory "/path/to/myapp/app/public"> # other setting here </directory> the .htaccess file redirects non-existing urls index.php: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^ index.php [qsa,l] i notice frameworks so, such symfony , zend, this tutorial. actual benefits having trouble of modifying virtual host file? why shouldn't have below instead without modifying virtual host file? security risk or something? root/of/project index.php .htacess public/ (html, image, css, etc) if keeping index.php , modifying virtual host file better, how can modify virtual host file i...

according defintions have read web server can serve http requests (e.g apache). a web container can serve servlets , jsps etc. since tomcat can both serve http requests , serve servlets , jsps considered both web server , web container. application servers jboss, glassfish fledged java ee servers include other containers apart web container. now in order application server glassfish work on own, needs web server(an http server) built it. therefore should contain webserver work on won, , if doesn't contain webserver built it, there should way plug existing web servers apache application server. what actual implementation? include webserver or should plug webservers these java ee application servers? yes, includes full web tier. java servlet spec covers of this.

i have daily data on several years several currencies. lag variables in data set 1 month (i.e. june 15 july 15, not 30 days). na's fine not possible. i have gotten far writing this: ddply(data, .(currency), function(x){ #first column date, 2nd currency, rest data. y=x[,-(3)] #this data want lagged y$date=as.date(y$date) %m+% months(1) #this increases dates 1 month x$date=as.date(x$date) #what data dont want lagged x[, (1:3)] below z=merge(x[,(1:3)], y, by=c("date", "currency")) #merge date, #lagged stuff merges non-lagged stuff 1 month later original obs date return(z) }) i can include data if necessary, given have works dont want spend time on it. i want check cant use lubridate %m+% months(1) syntax within lag function. have tried lag function package "statar" uses along_by syntax haven't been able figure out. thanks!

i have wcf service (s1) client , wcf service(s2) server. s1 consume s2 on net.tcp. s2 has 1 operation, return complex object of it's contents string. average size of object between 7-8 mb. recently had add more string contents actual object graph. cause s2 return following error the socket connection aborted. caused error processing message or receive timeout being exceeded remote host, or underlying network resource issue. local socket timeout '00:05:00'. system.net.sockets.socketexception (0x80004005): existing connection forcibly closed remote host @ system.net.sockets.socket.receive(byte[] buffer, int32 offset, int32 size, socketflags socketflags) @ system.servicemodel.channels.socketconnection.readcore(byte[] buffer, int32 offset, int32 size, timespan timeout, boolean closing) however, works expected when remove of string contents object graph. after doing bit of homework,i managed land on conclusion that, has size of returned obje...

in python, if have list l , want first x elements of it, call l[:x]. in c++, use vectors instead, don't know of easy way invoke first x elements of vector. there several ways: 1) create vector v consisting of first x elements as: std::vector<t> v { begin(l), begin(l) + x }; 2) pass first x elements function, pair of iterators: f(begin(l), begin(l) + x); where f accepts 2 iterators arguments — explore standard algorithms <algorithm> , of them work on pair of iterators. depending on use case, use of them.

i have issue consuming chunked http rsvp stream using camel. the stream here , can find more information @ end of this page i have created simple route such: from("http4://stream.meetup.com/2/rsvps").log(org.apache.camel.logginglevel.info, "meetupelasticsearch.log", "json rsvp ${body}") but nothing happens no message consumed. tried adding camel timer before because not sure can use http4 component directly in from result same. can me please? you cannot use http4 component in from() directive. however, there several ways call url , retrieve result: one create timer , call http4 component to() this: from("quartz2://httppoll/mytimer?trigger.repeatcount=0") .to("http4://stream.meetup.com/2/rsvps") .log("body is: ${body}") .to(mockdestination); another way use content enricher pattern if want example aggegates results 1 stucture. note well, if url dynamic must use recipientlist()...

could please advice how overcome problem described below: there application (it involves using hibernate , spring frameworks) 3 layers: dao, service , controller. want avoid saving duplicate entities in db. made using constraints @ db-level , in annotation in bean ( @table(name = "artist", uniqueconstraints = {@uniqueconstraint(columnnames = "artist_name")}) ). logic supposes if try add duplicate entity exception thrown. try process exception in service layer fails succeed. mean when explicitly notice exception thrown application can't proceed work because of exceptions. more clear cite code below: dao-layer @override public void saveentity(client client) { session session = sessionfactory.getcurrentsession(); session.save(client); } service-layer @transactional @override public boolean saveentity(artist entity) { boolean completedstate = false; try { //method dao-layer artistdao.saveentity(entity); } catch (cons...

since java 8 has made easier ever refer method directly (function/lambda), traditional reflection-based bean comparators (e.g. common-lang's equalsbuilder ) can implemented cleanly without reflection. wondering available in well-known library already? just clear, after function similar signature: static <t> boolean equals(t a, t b, function<t, ?>... proprefs); alternatively, non-confusion way of implementing using streams? given example class like class person { long id; string name, surname; int age; public long getid() { return id; } public string getname() { return name; } public string getsurname() { return surname; } public int getage() { return age; } } of course, can in compact form like @override public boolean equals(object obj) { if(obj==this) return true; if(!(obj instanceof person)) return false; person p=(person)obj; return stream.<functi...

a design question: i have singleton (in objective-c doesn't matter) the singleton class (object) data structure many classes access, , single (hence - singleton) now want add ability undo - saving snapshot of state of object - can go it. what need break singleton-ness of object (need 1 copy of it). not allow me share conveniently between classes. ideas? "the singleton class (object) data structure many classes access, , single" i think easier make singleton object have collection of data structure. create copies of data structure instead of copies of singleton.
