i want move set of artifacts 1 nexus other (download , later upload). can download artifacts 1 one, ¿is there way download entire folder? ¿is there other kind of operation export/import? thanks! edit: i have access nexus repository (sonatype-work\nexus\storage) in user folder. have got there artifacts. didn't find way web client. nexus stores artifacts on disk in standard maven 2/3 repository layout, can directly copy artifacts 1 storage directory other using whatever means like. after you're finished, schedule repair index task against destination repository searching artifacts web ui work. note builds work after copy artifacts, indexes not used maven builds.

i have code: echo $form->dropdownlist($model, 'defaultprinterid', chtml::listdata(printer::model()->findall(), 'id', 'name'), array('prompt' => '-- none--')); which gives me dropdown list this: <select id="labeltype_defaultprinterid" name="labeltype[defaultprinterid]"> <option value="">-- none --</option> </select> however, when form posts, adds value table defaultprinterid 0. instead of that, how make null, since it's nullable field? in controller, after load attributes $_post $model->defaultprinterid = $model->defaultprinterid ? $model->defaultprinterid : null; this changes 0 null otherwise leaves unmodified.

is there benefit storing constant value in shared memory? example: a[tid] = constant * b[tid] , where , b arrays, constant constant value e.g. 4. , tid thread index (array element = single thread). every thread has read value constant , shared memory should useful, right? how think works: reading global memory consume lot of time, read constatnt value global memory once shared memory , threads can read fast. since there many threads (constant value has read many times) shared memory should speed up. some cpu instruction sets, such x86, support storing full sized constants operands interleaved opcodes themselves. in case, constants read in rest of stream of instructions cpu running , seems unlikely storing them anywhere else can faster. other architectures, such arm, support storing small constants , shift values within opcodes. constants typically needed in program can represented small constant plus shift value , can therefore stored directly within opcodes. i...
