i learning mongodb , node.js , mongoose , want update mongodb , display on browser. code displays results prior update though know database has been updated. so example have 2 students called john , tom, when update third student called fred , try render results, gives me john , tom's details. here code: create: function(req, res) { console.log('creating model'); var newstud = new models.student({ surname: req.body.surname, firstname: req.body.firstname, } ); console.log('saving model'); newstud.save(); console.log('rendering model'); models.student.find({}, function(err,result){ console.log('finding results'); if (err) { throw err;} else { console.log('returning results'); res.send(result);

i'm learning how use angularjs building small app. i'm little confused controllers , models. have 3 controllers, 2 of nested. <div ng-controller="controller1 ctrl1"> <div ng-controller="controller2 ctrl2"> <div ng-controller="controller3 ctrl3"> </div> </div> </div> i using different model each controller display data. of data related in 1 way or another, wondering if should using 1 model instead. , if so, should defined? for example, 1 controller might like (function() { angular .module('app') .controller('controller1', controller1); function controller1() { this.data = data; } var data = [ { name: 'data 5', }, { name: 'data 6', }, { name: 'data 7', } ]; })(); where model defined in data . other c

let's have 2 disque instances: one instance running on port 7711 ip address 12.34.567.890 , password foo. another instance running on port 7712 ip address 98.76.543.210 , password bar. i'm able connect either instance typing: ./disque -h 12.34.567.890 -p 7711 -a foo or ./disque -h 98.76.543.210 -p 7712 -a bar if want join these instances using cluster meet command, possible? i noticed smilar thread relating redis cluster . i'm hoping run disque in docker container other services on single server, i'd have keep password protected. it possible join them because inter node communication happens on ports not password protected. if use different passwords won't easy client reconnect different node in case node fails. reason, work better if use same password nodes in cluster.

svn update command automatically resolves conflicts if 2 developers have modified same files. if appended line @ bottom while collegue inserted line in middle. when try update remote repository, change still @ bottom updated file. how can handled in git? everytime merge, have conflicts because of simple changes multiple developers on same files. svn , git apply incoming changes in same way: non-overlapping changes (local , remote) applied without conflict, overlapping changes produce merge-conflicts. both tools calculate context-aware chunks of changes . not examine text single-lines. if width of context in git bigger of svn (default svn 3 lines), you'll different results same sources. otherwise merging in git , svn should give same results.

i'm developing web application tv shows. , need database design. i made list of need, can't figure out how design it. have basic tables. series, episodes, seasons etc. can't how relate people episodes/series. here list: there should multiple people type. actor/director/writer/guest etc. i don't think creating seperate table each type idea. there should 1 people table. , need store type somewhere. a person may in 1 or many series. this can done people_serie table foreign keys people , series tables. need way relate person episodes too. an actor may play 1 or many roles. this can done person_role table. this getting complicating. a role may in 1 or many episodes in serie. a person may belong more 1 type in serie. ex: actor , director i hope make clear problem is. well, you're correct not split people table. the first thing add roles table, contain role id , role title (each column should unique - don't want 2 differen

im attempting input image method, when try draw image, comes totally black. i tried inputing 1 image , inputing whole mnist dataset. same result. https://github.com/lisa-lab/pylearn2/blob/master/pylearn2/expr/preprocessing.py if gcn true: trainingfolder = "../inputdata/converted_training/gcn/" testingfolder = "../inputdata/converted_testing/gcn/" img0 = (data[1,1:]).reshape((28,28)).astype('uint8')*255 im = image.fromarray(img0) im.show() #gcn# img_gcn = global_contrast_normalize(data) img_gcn_1 = image.fromarray(img_gcn[1,1:].reshape((28,28)).astype('uint8')*255) img_gcn_1.show() the second image, img_gcn_1 comes blacked. what doing wrong? have tried visualize image without multiplying 255? i.e., import matplotlib.pyplot plt img = img_gcn[:, 0] img = img.reshape(28, 28, order='f') plt.imshow(img, cmap=plt.get_cmap('gray')) i think procedure should work.
