i have class (class a) there exist many instances of @ run time. class uses class (class r) handles resource allocation. due fact second class (class r) doing resource allocation instances of class there must single copy of it. so looks this: class p (parent) class a[64], childs of class p each of these requires access single instance of class r i'm wondering best solution of this. let parent (class p) instantiate class r , pass instance each class a. problem : class p doesn't care class r , has no use it. seems daft have manage it. global variable, perhaps hidden in namespace problem : can use it, , should restricted class a. static variable inside class a, instances of class have access same instance of class r. problem : static class variables evil or i've not thought of? let class r contain instance itself, ie. singleton pattern. then can do: class { r *resource; public: a() { resource = r::getinstance(); } } and on use 'resource...

i facing little problem lldb, whenever want watch expression, error: error: watchpoint creation failed (addr=0x61f2e70, size=4). error: number of supported hardware watchpoints (0) has been reached and when watchpoint list -b it tells me number of supported hardware watchpoints: 0 no watchpoints set. is there command in lldb set maximum count of possible watchpoints / supported watchpoints? thanks the platform you're debugging not support hardware breakpoints, or if does, support not configured version of lldb you're using.

i have sbt + scalatest project. tests log in console this: [info] - should *** failed *** [info] java.lang.exception: ╧ЁштхЄ! that's not useful of cause.. exception text in cyrillic have set cp866 charset on console stream display correctly. i've tried console.setout(new printstream(system.out, true, "cp866")) but sbt ignores it. seems sbt constructs it's own stream logging various messages, can't find , how alter it.. there way add custom logger, it's overkill. i've found solution. can create custom logmanager val customlogmanager = logmanager.defaultmanager(consoleout.printstreamout(new java.io.printstream(system.out, true, "cp866"))) and set in project settings: logmanager := customlogmanager though, i'm not sure if best solution. 1 flaw have provide logmanager setting every project. inheriting build settings doesn't work reason.
