i working on osx app created using open source common lisp implementation called ccl. trying add in app purchases our app , read through storekitguide , wondering how able test in app purchases without using xcode. documentation gives instructions accessing sandboxed app store using xcode: when launch application xcode, store kit not connect app store. instead, connects special sandbox store environment. sandbox environment uses infrastructure of app store, not process actual payments. but doesn't tell how done without xcode. can done test in app purchases without xcode?

i have python script has batch command in between, batch_cmd = "batch command" subprocess.call(batch_cmd) consider scenario want repeat running batch command if fails. tried use try/except in such way batch_cmd has repeated in 'except' part too. is: try: batch_cmd = "batch command" subprocess.call(batch_cmd) except: print "error. retrying" subprocess.call(batch_cmd) the exception not getting caught, however. if batch command in try block fails, bypasses 'except' block , executes remaining of script. how can rewrite try/except part this? or there other method other try/except? know there have been similar questions on solutions have not helped me far. if want exception in case called command fails (nonzero exit code), use subprocess.check_call(batch_cmd) execute it. also use except subprocess.calledprocesserror: in case avoid catching more exceptions necessary.

there series of methods, i.e., const_defined?, const_get, or const_set, in standard ruby library. const_defined?, const_get, const_set and also, in active support core extensions of rails, "qualified_" counterparts these individuals exist. qualified_const_defined?, qualified_const_get, qualifeid_const_set is there can explain explicitly differences between bare , qualified forms these methods? thank in advance. hyo the qualified_ const helpers support interacting constants @ arbitrary depths (not children of subject). i think example easiest way explain one. let's foo::bar::baz exists: > object::const_get "foo::bar::baz" nameerror: wrong constant name foo::bar::baz > object::const_get "foo" => foo > foo.const_get "bar" => foo::bar > foo::bar.const_get "baz" => foo::bar::baz the qualified_ methods allow avoid walking module hierarchy directly: > object::qualified_con

do understand correctly typical way draw multiple objects each have different texture in opengl bind 1 texture @ time using glbindtexture , draw objects use it, bind different texture , same? in other words, 1 texture can "active" drawing @ particular time, , last texture bound using glbindtexture . correct? bind 1 texture @ time using glbindtexture , draw objects use it, bind different texture , same? in other words, 1 texture can "active" drawing @ particular time these 2 statements not same thing. a single rendering operation can use single set of textures @ time. set defined textures bound various texture image units. number of texture image units available queryable through gl_max_combined_texture_image_units . so multiple textures can "active" single rendering command. however, that's not same thing binding bunch of textures , rendering several objects, each object uses some (or one, in case) of bound textures
