which language faster web, java or php? it difficult 1 answer in theory java should faster: it's precompiled, trivial algorithim run faster in java php , there has been vast amount of work done optimise java improving code, standard libraries, jit compilers, etc. php loaded , interpreted every time if you're not using zend optimiser, objects intialised on every execution, trivial string varaible complex object many methods support. the problem in practice php sites seem run faster using fewer resources. i think because php developers take more straightforward approach design , don't lost trying implement exotic design patterns , implementing endless pointless abstractions.

i have n:m-association between 2 classes user , role, implemented bag lazy="extra". association stored an association table sind user can have many roles , role can associated many users. now when add new role user, hibernate emmits sql code first removes entries in th eassociation table adds them again plus new association. i'd know why happens , how can rid of behavior. ralf i've found solution myself: hibernate bags first delete alle entreis , rebuild new state. if use set, association maintained. see hibernate manual, improving performance

i'd automate tortoisesvn part of commit process. i'd dynamically create log entry commit dialog. i know can launch commit dialog either commandline or right clicking on folder , selecting svncommit. i'd use start commit hook setup log entry. thought worked passing entry file name in messagefile variable when add hook script cannot see variable (hook launched after right clicking , choosing svncommit). when try using commandline use /logmsgfile parameter seems have no effect. i'm using tortoisesvn 1.5.3. looks own misunderstanding of the api caused problem. solution: 1) i've added start commit hook script tortoisesvn using hooks gui in settings area of right click menu. 2) script receive 3 pieces of information: path messagefile cwd details see: manual these passed command line arguements script - reason had thought set temporary environmental variables. my script opens file specified second arguement , adds in custom text. ...

imagine 2 languages (apart type information) have same syntax, 1 statically typed while other 1 uses dynamic typing . then, every program written in statically typed language, 1 can derive equivalent dynamically typed program removing type information. not neccessarily possible other way around, class of dynamically typed programs strictly larger class of statically typed programs. let's call dynamically typed programs, there no mapping of variables types making them statically typed " real dynamically typed programs". as both language families definitly turing-complete, can sure every such real dynamically typed program there exists statically typed program doing same thing, read "experienced programmers able write elegant code in dynamically typed languages". ask myself: there examples of real dynamically typed programs, equivalent statically typed programm more complex / less "elegant" (whatever may mean)? do know of such exampl...

i'm playing around html_quickform generating forms in php. seems kind of limited in it's hard insert own javascript or customizing display , grouping of elements. are there alternatives quickform might provide more flexibility? if find hard insert javascript form elements, consider using javascript framework such prototype or jquery . there, can centralize task of injecting event handling form controls. by that, mean won't need insert event handlers html form code. instead, register events somewhere else. example, in prototype able write this: $('myformcontrol').observe('click', myclickfunction) also have @ answers another question . /edit: of course, can insert custom attributes , event handlers form elements using html_quickform. however, above way superior.

is global memory initialized in c++? , if so, how? (second) clarification: when program starts up, in memory space become global memory, prior primitives being initialized? i'm trying understand if zeroed out, or garbage example. the situation is: can singleton reference set - via instance() call, prior initialization: mysingleton* mysingleton::_instance = null; and 2 singleton instances result? see c++ quiz on on multiple instances of singleton... yes global primitives initialized null. example: int x; int main(int argc, char**argv) { assert(x == 0); int y; //assert(y == 0); <-- wrong can't assume this. } you cannot make assumptions classes, structs, arrays, blocks of memory on heap... it's safest initialize everything.

is there more concise way write following c++ statements: int max = 0; int u = up(); if(u > max) { max = u; } int d = down(); if(d > max) { max = d; } int r = right(); max = r > max ? r : max; specifically there way embed assignment of functions return inside if statement/ternary operator? assuming that: the idea remove local variables (i.e. don't need u , d , r later on) evaluation order doesn't matter ... can use std::max : int m = max(max(max(0, up()), down()), right()); if return value of function: return max(max(max(0, up()), down()), right()); note that can evaluate functions in order, rather string up, down, right order in original code.

what best method adding options select json object using jquery? i'm looking don't need plugin do, interested in plugins out there. this did: selectvalues = { "1": "test 1", "2": "test 2" }; (key in selectvalues) { if (typeof (selectvalues[key] == 'string') { $('#myselect').append('<option value="' + key + '">' + selectvalues[key] + '</option>'); } } a clean/simple solution: this cleaned , simplified version of matdumsa's : $.each(selectvalues, function(key, value) { $('#myselect') .append($('<option>', { value : key }) .text(value)); }); changes matdumsa's: (1) removed close tag option inside append() , (2) moved properties/attributes map second parameter of append(). same other answers, in jquery fashion: $.each(selectvalues, function(key, value) { $('#myselect') ...

i've created windows service in c# , windows server 2003. service able run exe file windows forms application. when start service - runs other application cannot see it. when open task manager - can see application running cannot see it. have checked "allow service interact desktop" nothing happens. please help. possible run , exe within windows service , see exe running in widnows server 2003? showing ui windows service problematic because service may running on different desktop user (and on vista/server 2008 in fact run on different desktop). the easiest solution run ui not directly service application running on user's desktop (maybe set run @ login) communicate service somehow. just remember: there may no logged in user there may multiple logged in users using fast user switching or remote desktop the application on user desktop running in user's security context, not service's

most of literature on security talks importance of defining security policy before starting workout on mechanisms , implementation. while seems logical, quite unclear defining security policy means. has here had experience in defining security policy, , if so: 1) outcome of such definition? form of such policy, distributed system, document containing series of statements on security requirements (what allowed , not) of system? 2) can policy take machine readable form (if makes sense) , if how can used? 3) how 1 maintain such policy? policy maintained documentation (as rest of documentation) on system? 4) is necessary make references policy document in code? brian you should take 1 of standard security policies , work there. 1 common pci compliance (payment card industry). it's thought out , except few soft spots, good. i've never heard of machine readable policy except microsoft active directory definition or series of linux iptables rules. https:/...

i have requirement create simple database in access collect user data loaded database further reporting. there module in access db when invoked user (probably clicking button) output query delimited file. user needs mechanism (for example form button) transfer file remote server, using sftp. have idea of how accomplish this? you can write call sftp command line client via batch file if want accomplish that. check out shell() function in vba. under click event of button on form add in code: mysftpcall = "sftp <insert options here!>" call shell(mysftpcall, 1) i've used before copy files straight across network shares etc. share data in-house access db. of course more fancy if necessary.
