i must overthinking or something. i've read on parsley form validation site and, far can tell, passively responds attributes set in dom. needs component change attributes before 1 has working form. since i'm using angular, presumably, parsleyjs angular. i'm trying have save button disabled until form valid. think form validation 102. their super-simple demo doesn't have save button , doesn't bother showing css, frankly i'm not sure supposed demonstrating. if i've got write css , form validation, i'm not sure parsley doing me. http://parsleyjs.org/doc/examples/simple.html what i'd find plunkers showing parsley working end-to-end, don't seem believe in plunkers. don't seem find example form validating , setting value true or false can capture use in controller. (this sounds negative, i'm not down on parsley, i'm stumped , time running out.)

does cdi @transactional(transactional.txtype.requires_new) works when called inside same bean: @transactional public void method1() { for(...) { method2(); } } @transactional(transactional.txtype.requires_new) public void method2() { ... } i suppose doesn't works because local calls can't intercepted proxy. in case recommeded usage pattern if want manage each call of method2 in new transaction. obvious 1 create bean, it's don't like. interception of local method calls not work cdi , cannot inject class directly (cyclic dependency). see cdi call interceptor annotated method within same instance the self injection issue still open, see https://issues.jboss.org/browse/cdi-414

what idiom performing more 1 reduction in single pass of stream? have 1 big reducer class, if violates srp if more 1 type of reduction computation required? presumably want avoid making multiple passes, pipeline stages might expensive. or want avoid collecting intermediate values in order run them through multiple collectors, since cost of storing values might high. as brian goetz noted , collectors.summarizingint collect int values , perform multiple reductions on them, returning aggregate structure called intsummarystatistics . there similar collectors summarizing double , long values. unfortunately these perform fixed set of reductions, if want reductions different do, have write own collector. here's technique using multiple, unrelated collectors in single pass. can use peek() take crack @ every value going through stream, passing through undisturbed. peek() operation takes consumer , need way adapt collector consumer . consumer collector's accumu...

our windows application (developed in delphi) shipped in 32-bit , 64-bit editions. users can write plugins it. if target 32-bit edition, need create 32-bit dll. if target 64-bit edition, need target 64-bit dll. i create sample application in visual studio c++ can used reference hacking it. i visual studio solution provided example able have in place compile sample dll both win32 , win64. which minimum (preferably free) visual studio c++ edition or version need able compile both win32 , win64. tried visual studio 2010 express not seem let add win64 target platform. vs2012 express includes 64 bit compiler. possible persuade earlier versions of express edition use 64 bit tools, it's quite tricky set up.
