so i'm developing application on top of dropwizard , in 1 component have call external rest service. want using jerseyclient. now there 2 implementations available, 1 dropwizard , 1 jersey. using builder have choose between io.dropwizard.client.jerseyclientbuilder.jerseyclientbuilder and org.glassfish.jersey.client.jerseyclientbuilder now former requires environment jerseyclientconfiguration being passed it. is there reason using dropwizard implementation on vanilla one? what's difference (except timeout)? thank you after more digging , asking around, got answer (below). seems better use jerseyclientbuilder comes dropwizard better integrated: one can use jerseyclientconfiguration in order configure jerseyclientbuilder via application configuration (service.yml file). passing environment information enables use of managed thread pool integrated within dropwizard's lifecycle, when dropwizard gets shut down, client. dropwizard's metrics inte...

i have tried simple nancy example model binding , documentation ( https://github.com/nancyfx/nancy/wiki/model-binding ) says fields usable properties, in practice seem bind when use properties. is documentation right (if so, why isn't model binding?) or documentation wrong (if so, why?) model binding fields wasn't supported until v1 . long you're using v1 or newer should work out of box. if doesn't provide code reproduces issue along version of nancy you're using? since documentation targets recent version can confusing features supported in each version. @ moment best place find version information changes on breaking changes page .

i using recyclerview cursors following set up, recyclerview adapter cursorrecyclerviewadapter . items have image , textviews. recyclerview not going have more 5-7 items @ max. my question is, there way tell recyclerview load more items ones shown in screen? because of imageviews, 2 present on screen , when scrolling others load not smooth should be. there way tell recyclerview load 4 if 2 not showing on screen? well, basic concept of recyclerview recycles views go out of screen , reuses them (when not visible) show next items in list. minimum number of views loaded memory , views recycled in loop according position. is there way tell recyclerview load more items ones shown in screen? if want load more items user can see on screen, think might not possible recyclerview . workaround : if have small list (as suggest) use listview or gridview can desire.
