in current framework's design, peruse types of specific assemblies , work based on types found. assemblies searches through determined application bootstrapper/initializer. assemblies compiled in, can referenced via: typeof(sometypeintheassembly).assembly . nice because bootstrapper code has strong reference type in assembly , there's no fumbling qualified names inline strings need manually kept up-to-date if assembly qualified name changes. didn't referencing unrelated type in assembly , being dependant on type being there. (what if moves assembly? if deprecate/delete type? change namespace?) in code, looks bit weird too: frameworkassemblyreader.read(typeof(someassemblynamespace.subnamespace.graphingcalculator).assembly); now in bootstrapping code, have direct dependency (although pretty trivial dependency) on graphingcalculator has nothing bootstrapping stage (and graphingcalculator, has nothing obtaining assembly references). avoid this, in each assembly...

i'm using javascript library visualize rrdtool data , using rrdtool xport retreive data rrd files. today noticed following: when viewing data now-1day: there datapoint of 100 when viewing data now-31day, datapoint of 100 seen... how can make sure datapoints within specified time when using xport? i'm using --step 10, didn't make difference. no matter --step set doesn't used. read because ignored if it's less 1 pixel, what's suggested solution problem? additional info: i'm using collectdtool default rrdtool plugin options: http://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_rrdtool edit: seems essence of rrdtool have several archives 1 month, 1 day, 1 year etc, makes sense can't every single datapoint archive 1 month? the number of data points depends on available data ... if high-resolution rra covers 30 days (for example) data lower resolution rra once request data more 30 days.

in main can read config file, , supply runreader (somefunc) myenv fine. somefunc doesn't need access myenv reader supplies, nor next couple in chain. function needs myenv tiny leaf function. how access environment in function without tagging intervening functions (reader env) ? can't right because otherwise you'd pass myenv around in first place. , passing unused parameters through multiple levels of functions ugly (isn't it?). there plenty of examples can find on net seem have 1 level between runreader , accessing environment. i'm accepting chris taylor's because it's thorough , can see being useful others. heatsink 1 attempted directly answer question. for test app in question i'll ditch reader altogether , pass environment around. doesn't buy me anything. i must i'm still puzzled idea providing static data function h changes not type signature of g calls , f calls g. though actual types , computations involved unchanged. se...

i trying display loader-dialog in thread because when start upload system of files can't see window until processing finished. i tried this: thread.start_new_thread(self.display_loader(),(self)) but didn't work. there special way run new window in thread? everything done python , pygtk when self.display_thread() , call display_thread function right there, , pass return value first argument thread.start_new_thread . that's not intended. that said, think you're better off doing other way around; let main thread own ui, , loading off in thread. remember gtk+ not thread-safe, it's absolutely best all interaction gtk+ single thread. update : actually, above perhaps over-simplifying bit, it's "common truth" i've understood (i've been using gtk+ ~15 years seldom threads). this article re-states in more forgiving way, not sure if makes life easier in case, though. wanted mention in completeness' sake.

from have understood, not best way open project built maven in intellij using idea plug-in, calling: mvn idea:idea but open directly pom file (intellij has default plug-in maven); same thing, eclipse. could provide arguments on why better approach? this applies equally intellij , maven: changing pom.xml file not reflected in ide, must rebuild project (possibly losing configuration (?)) every time. moreover, if team member modifies pom.xml , have remember rebulding project (which require closing , reopening it). additional step required when opening new project ides have other maven features, e.g. both of aforementioned environemnts can show dependency graphs use mvn plugin last resort when ide goes crazy , cannot figure out maven configuration correctly.

is possible override constructor of base class in derived class? if so, how can accomplished , in use case practical? if not, why not? no, can't override constructors. concept makes no sense in c#, because constructors aren't invoked polymorphically. state class you're trying construct, , arguments constructor. constructors aren't inherited @ - constructors derived class must chain either constructor in same class, or 1 of constructors in base class. if don't explicitly, compiler implicitly chains parameterless constructor of base class (and error occurs if constructor doesn't exist or inaccessible).
