preprocessor - Adjust data vector to have certain variance -

i have set of integers x, 0<=x<=255 need transform data in way : average of values in set == 0 variance == 1 i can meet first condition with: array arr[]; av = average(arr); foreach(x in arr) { x = x - av;} but not know, how meet second one. the best idea have: compute current variance , divide or multiply integers closer desired variance. a=a/2 , repeat until error small. (resembles basic algorithm of estimating square root of x.) is there (more efficient) way of achieving this? after meeting first condition, need divide every number standard deviation.

c++ - Can we say bye to copy constructors? -

-
copy constructors traditionally ubiquitous in c++ programs. however, i'm doubting whether there's reason since c++11. even when program logic didn't need copying objects, copy constructors (usu. default) were included sole purpose of object reallocation . without copy constructor, couldn't store objects in std::vector or return object function. however, since c++11, move constructors have been responsible object reallocation. another use case copy constructors was, simply, making clones of objects. however, i'm quite convinced .copy() or .clone() method better suited role copy constructor because... copying objects isn't commonplace. it's necessary object's interface contain "make duplicate of yourself" method, sometimes. , when case, explicit better implicit. sometimes object expose several different .copy() -like methods, because in different contexts copy might need created differently (e.g. shallower or deeper). in conte

let's want define classes of following structure: struct myclass { int x; bool y; float z; myclass(qvariantmap data) : x(data["x"]), y(data["y"]), z(data["z"]) {} }; as can see, have qvariantmap (something similar std::map<std::string, boost::variant<...>> of not familiar qt) want able construct such type no further knowledge of fields, hence convenient constructor should "deserialize" fields map. i need several classes of style, , want definitions clean possible maximum maintainability (regarding typos in string keys), readability , automation. i thought of macro structure following: def_class(myclass)( def_field(int, x) def_field(bool, y) def_field(float, z) ); i don't see problem when want generate fields not constructor (the other way around possible, i'll demonstrate former only): #define def_class(classname) \ struct classname { \ _def_class_tail/*..."curry

validation - Form - need to allow for apostrophes -

-
i have form written in classic asp light client-side validation. works except 1 thing - form fails when there's apostrophe. 1 of fields may have apostrophes (last name field - form fail if user's last name o'brien, example). how fix this? you'll have examine asp code. if see code looks like string sql = "select user_id, first_name,last_name users username = " + myusername; where myusername comes user, vulnerable. the fix not try escape input (i.e., replace "'" "''") use different method outlined in article on sql injection , how avoid it in nutshell, try following bobby-tables site string username = "joe.bloggs"; sqlcommand sqlquery = new sqlcommand( "select user_id, first_name,last_name users username = ?username", sqlconnection); sqlquery.parameters.addwithvalue("?username", username);

How can I make android delete old native libraries? -

-
i'm trying delete native libraries application because don't use them anymore, after install apk in phone can see native libraries still there. i've seen, android copy/update native libraries correctly replacing file in libs/ directory, apparently doesn't delete them when they're not in apk anymore. how know libraries still there? first of application's size remains same , i'm deleting big libraries, , second, if leave system.load(...) statement app still able load library. the solution i've found has been uninstall app , make fresh install, that's not obvious solution user updating app google play, , yes problem affects severely app functionality. i've checked , apparently can delete files self, during service creation, don't want mess installation way. do know if there's way tell android needs delete native libraries , copy them again? thanks, mike [edit] i've found gb updates libraries correctly, deletes now-missing

user interface - can C# read in a xml file to change its gui at runtime -

i making application generate , sql scripts template , after taking input different fields user. there many templates, gui needs adjust fields user filling out. in interest of keeping scalable, i'd rather not hardcode guis program, have read xml file , change based on template user has selected. this preferred because if new template arise, program needs xml file corresponds template. , actual code not need changed. have eyes set on using c# this, have experiences using it. open suggestions other languages though. edit: project work, , wanted sure possible c# before convincing employers expand using c#. you sort of thing subclassing windows.forms.form , adding constructor accept xml file parameter. add parser xml file interpret instructions labels , fields want add consistent form design (say, 2 columns label field name on left , actual input field on right, achievable filling form tablelayoutpanel). need lay out design constraints beginning , stick them.
