"supported resource types , properties" in https://cloud.google.com/deployment-manager/configuration/create-configuration-file has "container.v1beta1.cluster", link broken. that link fixed now: google container engine api the cloud deployment manager uses underlying apis work, if api exists, should able use cloud deployment manager it. quoting docs: remember deployment manager uses underlying apis of google cloud platform services manage resources in deployment. if api doesn't support action, deployment manager cannot perform action either. example, deployment manager can update existing resource if there update method in corresponding api. so should able create cluster cloud deployment manager.

i have char array collect names, positions not being initialized empty. if value entered, rest of positions empty, if nothing entered, positions filled "weird" characters. how can fix this? depends on how you're initializing array. statically allocated arrays (arrays outside of function not dynamically allocated): char arr[20] = {0}; void function( void ) { // stuff happens here array } for automatic arrays (arrays within scope of function not dynamically allocated): void function( void ) { char arr[20] = {0}; // stuff happens array , cannot // accessed outside function } for dynamic arrays, use calloc() dynamically allocate , initialize 0: size_t len = 20; char *arr = calloc ( len , sizeof(char)); you can use memset() clear arrays: char arr[20]; memset (arr, 0 , sizeof(arr));

i'm developing app api level 15+ has jni code , i'm wondering if there devices armeabi abi (armv5) , api level 15+ can include armeabi-v7a , x86 libraries , skip old armeabi? android doesn't support arm versions below armv7 android 4.4 (api level 19). since android 4.0 (api level 15), doesn't support armv5/armv6 default can modified build platforms (see https://groups.google.com/d/msg/android-building/q_gu1zb6dlc/bq5qryioq_kj ), , there custom builds run on armv6. i'm not entirely sure if there official, certified compatible devices run such combination (android 4.0-4.3) though - there should @ least not such certified devices running android 4.4, since compatibility definition document strictly requires armv7 version. so in practice should pretty safe skip it, might exclude fringe third party roms doing that. see https://stackoverflow.com/a/28926267/3115956 similar answer similar question.

how force md-select in multiple mode behave like <select multiple required ... > ? here fiddle, show mean. in example, browser doesn't let me submit form without selecting @ least 1 option select tag. i want md-select behave similarly, don't know how can - neither putting 'required' attribute nor adding 'ng-require' directive helps. you can rely on angular validation this, rather browser. here's forked example: http://codepen.io/anon/pen/rvglzv specifically: <button type="submit" ng-disabled="myform.$invalid">submit</button> to keep submit button disabled until form valid and, <form novalidate name="myform"> to name form , tell browser not own validation on it. you add css class ng-invalid show red around invalid fields. edit: make sure put ng-model on <select multiple> , otherwise required attribute won't work.

we need integrate search engine in our plataform catalog management software in share point. information stored in multiple databases , storage of files ( doc , ppt , pdf .....). our dev platform asp.net , have done pre-liminary work on lucene, found good. however, came know of solr. need continue using lucene, need defend solr. please accepted. , sorry english. lucene full-text search library used provide search functionalities application. can't used application itself. solr complete search engine built around lucene providing search functionalities , others. solr web application can used without development around it. if need search engine called application recommend use solr.

i using umbraco 7 , have written custom code on following events umbraco.core.services.mediaservice.saved += new umbraco.core.events.typedeventhandler<imediaservice, umbraco.core.events.saveeventargs<imedia>>(mediaservice_published); umbraco.core.services.contentservice.saved += new umbraco.core.events.typedeventhandler<icontentservice, umbraco.core.events.saveeventargs<icontent>>(contentservice_published); for content, generating media folder , vice versa. the following code causes other method fired. var newcontent = contentservice.createcontentwithidentity(mediaitem.name, obj.id, "somecontentalias"); and... var newmedia = mediaservice.createmediawithidentity(contentitem.name, obj.id, "somemediaalias"); i have used save method update nodes before, , has parameter of raised events... contentservice.save(contentitem, 0, false); is there way can create new media item identity , suppress event being raised? no,

our code base has collection of components. each component contains "common"/reusable code in form of independent projects built static libraries. examples of components: ui widgets, containers, networking, etc. when write unit test our ui widgets, building executable links against "ui widgets" static library. when comes mocking, makes things complicated. normal mocking methods i've read (dependency injection / inversion of control) demonstrated in such way seems difficult (if not impossible) when code being mocked has been compiled. if ui widgets static library contains implementation of 20 classes, might need mock 5 of those. need somehow tell test executable use 15 symbols static lib ignore 5 (and favor mocked implementations in either library or ideally compiled test executable directly). how can mock classes in static library effectively? can think of ways using runtime polymorphism + interface pattern, i'd love able mock using templates wel

while working on separating applications data domains , make them work independently 1 cannot avoid references other domains. while data domain should accessible via api couldn't find answer on how design reference between domains are they api centric database agnostic not losing database functionalities grouping the image should visualize intend, though right approach here? when multiple systems have interact each other, i'd recommend using guids store references between them. as per description, guids used globally uniquely identify something, regardless of , it's stored. if have multiple systems storing data in different places, , you'd need merge/group them , ensure uniqueness, use guids. are: unique across tables, databases, servers, can safely join/merge data stored in different places predictable, no need insert in table generate it no need of central authority, if multiple systems registering orders, example, , need share them, th
