java - Looking distributed cache solutions for implementing a distributed MVC pattern -

-
i building client/server application have complex (but not large -say 10,00 objects) object model @ heart. multiple clients need view model (via eclipse rcp gui), server node can directly edit model. want edits model published out clients. new clients able request model, , register updates. its standard model-view-controller pattern really. can suggest good, open source, replicated cache solutions handle distribution of object model, plus distributing changes model. want 'deltas' sent clients, rather sending complete model every time 1 field changes. also, need able replicate object graph , maintain coherence, e.g., if have 'person' object: public class person implements serializable { private person manager; private string name; public person (person manager, string name) { add 3 people cache: person boss = new person(null,"theboss"); person employee1 = new person(boss,"employee 1"); person employee2 = new person(boss,"

Hit-Count (reads) of an array in Java -

-
for evaluating algorithm have count how items of byte-array read/accessed. byte-array filled contents of file , algorithm can skip on many of bytes in array (like example boyer–moore string search algorithm). have find out how item read. byte-array passed around multiple methods , classes. my ideas far: increment counter @ each spot byte-array read. seems error-prone since there many of these spots. additionally have remove code afterwards such not influence runtime of algorithm. use arraylist instead of byte-array , overwrite "get" method. again, there lot of methods have modified , suspect there performance loss. can somehow use eclipse debug-mode? see can specify hit-count watchpoints not seem possible output hit count?! can maybe reflection api me somehow? somewhat 2), in order reduce effort: can make java method accept arraylist wants array such transparently calls "get" method whenever item read? there might out-of-the-box solution i

Iphone SDK UITextView text length -

how can know text out of fit (that text need scrolled)? have methods or this? thanks. use nsstring uikit additions. allow calculate height of string given size , font. can calculate height in way: cgfloat textviewwidth = cgrectgetwidth(textview.bounds); cgsize inset = cgsizemake(5.0,5.0); cgsize stringsize = [mystring sizewithfont:textview.font constrainedtosize:cgsizemake(textviewwidth-2*inset.width,1024) linebreakmode:uilinebreakmodewordwrap]; bool textoutoffit = stringsize.height+2*inset.height>cgrectgetheight(textview.bounds); note code requires fine tuning. infact text inside text views has internal margin (that took account using inset structure), required text view height higher calculated string height. code ask nsstring calculate size when horizontally constrained in textview boundaries (while 1024 in height maximum uiview height possible). check if returned string height inside or not text view boundaries.

c++ - Implicit Template Parameters -

-
the following code generates compile error in xcode: template <typename t> struct foo { foo(t value) { } }; int main() { foo myfoo(123); return 0; } error: missing template arguments before 'myfoo' changing foo myfoo(123); foo<int> myfoo(123); fixes issue, shouldn't compiler able figure out appropriate datatype? is compiler bug, or misunderstanding implicit template parameters? the constructor in theory infer type of object constructing, statement: foo myfoo(123); is allocating temporary space myfoo , must know fully-qualified type of myfoo in order know how space needed. if want avoid typing (i.e. fingers) name of particularly complex template, consider using typedef : typedef std::map<int, std::string> stringmap; or in c++0x use auto keyword have compiler use type inference--though many argue leads less readable , more error-prone code, myself among them. ;p

sql - Insert select continue with error -

-
i have sql scripts use insert secondtable (field, field1) select field, field2 table; i use oracle 9.x , sqldevelopper. when launch them, on insert select foreign key error(s). , didn't insert set work. is possible oracle continue same when error appear , if possible display or log error ? you can't continue failed set-based insert in oracle 9. either have make statement failsafe, or accept rolled back. options: if such errors rare, try set-based effort , add exception handler row-based solution if error occurs, , displays errors (or stores them somewhere further processing) when errors occur. yes, duplicates effort times doing efficient operation , when errors occur handle them decide. if common occurance, suck , switch row-based solution above. optimize best can , hope someday can take advantage of #3) upgrade oracle 10 , take advantage of dml error logging

Ruby On Rails - "undefined method `id' for 4:Fixnum" -

i decided wanted list users in ruby on rails application - since couldn't figure out how list them other way, decided use partials. have following on administration page (just hooked own administration controller): <%= render :partial => user.find(:all) %> i have file called _user.html.erb in users view folder. contains following: <ul> <% div_for @user.object_id %> <li><%= link_to user.username, user.username %></li> <% end %> </ul> when application runs , go administration page, following error: undefined method `id' 4:fixnum it says it's because of line (which in partial file): <% div_for @user.object_id %> i'm unsure why happens (and have googled hours try , find results , find solutions don't work me). think it's usage of @user instance variable, i'm not totally sure. you error because div_for expects active record object argument, calls id method on. pass

ASP.NET MVC data annotate domain model in the web project -

-
i've seen somewhere how before on blog forgot or how. lets have domain in class library. i'd data annotate properties of domain viewmodel in web project. how accomplish this? for example. domain in class library: public class person { public int id {get; set;} public string firstname {get; set;} } in web project, there this: //do need set attribute here? public class createpersonviewmodel{ [required()] [displayname("first name")] public string firstname {get; set;} } this code can mapped person without tool. partial or something. the whole idea of using view model decouple domain model , have adapted needs of view. view model should declared in web project , contain necessary properties , formatting attributes particular view might require. domain model shouldn't polluted view specific data annotations. if model looks this: public class person { public int id { get; set; } public string firstname { get; set; } }
