when using singletons, if class has instance fields should careful when several threads might using singleton? (and fields mutable , values can changed) i havn't tried in theory seems answer yes , need synchronization (or skip singleton) when access object (or same mutable data) multiple threads (or processes) need kind of synchronization. there no difference whether singleton or other "non-singleton" object. one additional question, in case of singletons creation of singleton though, if created first time used, first time might concurrently different threads, need synchronize singleton-creation well.

i got strange result for: console.writeline(new datetime(1296346155).tostring()); result is: 01.01.0001 0:02:09 but not right! i parsed value 1296346155 file. said in utc; please explain;) thank help!))) datetime expects "a date , time expressed in number of 100-nanosecond intervals have elapsed since january 1, 0001 @ 00:00:00.000 in gregorian calendar." (from msdn ) this question shows how can convert unix timestamp datetime.

i need reasonable supply of high-quality random data application i'm writing. linux provides /dev/random file purpose ideal; however, because server single-service virtual machine, has limited sources of entropy, meaning /dev/random becomes exhausted. i've noticed if read /dev/random, 16 or random bytes before device blocks while waits more entropy: [duke@poopz ~]# hexdump /dev/random 0000000 f4d3 8e1e 447a e0e3 d937 a595 1df9 d6c5 <process blocks...> if terminate process, go away hour , repeat command, again 16 or bytes of random data produced. however - if instead leave command running same amount of time, much, more random data collected. assume on course of given timeperiod, system produces plenty of entropy, linux utilises if reading /dev/random, , discards if not. if case, question is: is possible configure linux buffer /dev/random reading yields larger bursts of high-quality random data? it wouldn't difficult me buffer /dev/random part of progr...

we have main application loads several plugins have own individual icons , child windows. problem in windows 7, icon in taskbar icon of main application, on child windows. however, alt+tab menu displays appropriate icon. i understand due pinning feature, , windows 7 uses icon of main exe handle this. is there way can change taskbar icon on our child windows? , possibly disabled pinning well? confusing able pin these child windows, wouldn't work properly. you can't pin child window - pinning works @ level of application. if pin/unpin child window, you're (un)pinning app whole. there's no way disable behaviour, since it's os-level functionality applies window in taskbar (though choose not display windows in taskbar). i'm not sure window icons, i'd imagine you're right when it's using application icon.
