when idea use crdt instead of paxos or raft? if can use crdt, so. should better performance. enables interesting use cases such working offline , merging later. not possible design things such crdt work you. in case, paxos can solve hard problems you. but if you've decided use paxos, should limit how work being done directly through paxos algorithm. instead performance reasons want reserve paxos necessary operations such master election, , let replicated master setup handle decisions. (in high throughput environment master delegate responsibility specific shards specific children, replicate off each other. not let master become bottleneck...) that said, easier claim you'll wave magic wand of paxos in practice. in light may find http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en/us/archive/chubby-osdi06.pdf interesting description of difficulties real-world paxos implementation encounter.

does know if there in java similar notifypropertychanged in c#? have been searching around, , there no proper answer. here senerio: in fact,i working on android application. applications read data remote bluetooth device via bluetooth socket. once data received socket, data decoded decoder(it class) , update value ui. however, have decoder class decode data bluetooth device , activity manage display value ui. need pass decoded value decoder ui. think need notifypropertychanged event, when there updated value decode, inform activity class update ui. pure java (not android specific) have interface typically used beans handle property change events can use. classes involved are: propertychangesupport class extend in order fire change notifications inside of setter methods. propertychangelistener instances register , listen change events. propertychangeevent objects encapsulate data passed change. here's article oracle docs describing interface in more deta...

i edit long files in vim have blocks of code in multiple disparate places in file need going , forth between. obviously, 1 way of solving split window :split , edit each portion in different split window, , :w in either window save whole file. , if have large enough screen have use vim on low-resolution laptop , don't want reduce screen space further splitting window. in case, i'd edit file in multiple tabs , , treat each separate tab separate view split. can sort of mimic using :tabopen <the same filename> once have 1 copy of file open, sort of hacky — doesn't work if i've made changes file because vim thinks i'm opening file second time. is there way behavior want tabs in vim? the :tab command takes command argument. so can this: :tab split this work if buffer modified, , save in either tab saves file, updating saved state in both.
