i'm using clearfix prevent bootstrap grid breaking when use columns of different heights. however, once clearfix div added document, columns appear after in source behave if have different even/odd index do. i have created relevant demo . can see, removing clearfix div, makes colors of divs change if index has changed. do know may causing , can correct it? if @ nth-of-type definition specifies the :nth-last-of-type(an+b) pseudo-class notation represents element has an+b-1 siblings same expanded element name after in document tree, 0 or positive integer value of n, , has parent element. see :nth-child() pseudo-class syntax of argument. the key thing here states: the same expanded element name so taking quite literally, css selector targets specific element , odd , matched on specific element name , not elements matched using specific selector. this why replacing div with span work never matched different element.

i writing notes compare apply() , sweep() , discovered following strange differences. in order generate same result, sweep() needs margin = 1 while apply wants margin = 2. argument specifying matrix uppercase x in apply() lowercase in sweep(). my.matrix <- matrix(seq(1,9,1), nrow=3) row.sums <- rowsums(my.matrix) apply.matrix <- apply(x = my.matrix, margin = 2, fun = function (x) x/row.sums) sweep.matrix <- sweep(x = my.matrix, margin = 1, stats = rowsums(my.matrix), fun="/") apply.matrix - sweep.matrix ##yup same matrix isn't sweep() "apply-type" function? r quirk or have lost mind? note apply , if each call ‘fun’ returns vector of length ‘n’, ‘apply’ returns array of dimension ‘c(n, dim(x)[margin])’ if ‘n > 1’ in example, margin can (and should) set 1 in both cases; returned value apply should transposed. easiest see if original matrix not square: my.matrix <- matrix(seq(1,12,1), nrow=4) apply.matrix <- t(app

in absence of signalling server coordinating initial exchange, webrtc provide way allow responder send information freely caller, if responder has received offer , has no other methods of communication caller? (there's no signalling server because web app must useable offline. method establish connection 1 exchange of information useful.) sorry, it's long , weird question. webrtc needs signalling system establishing peer peer connection. thing notice why needs signalling. in process of establishing peer connection 2 parties exchange sdp contains information such ip , port @ both ends @ media/data packets exchanged. contains encoding/decoding or codec used plus many other useful things.thus without exchange of these packets between both parties communication can't possible. that why not possible @ least in case of webrtc without communication both sides peer connection can established.

i'm attempting create analyzer roslyn prevent use of asserts within given namespace (to ensure project design standard maintained). i've been able point can verify if assert, unsure how namespace context. public override void initialize(analysiscontext context) { context.registersyntaxnodeaction(analyzemethod, syntaxkind.invocationexpression); } private static void analyzemethod(syntaxnodeanalysiscontext context) { var expression = (invocationexpressionsyntax)context.node; var memberaccessexpression = expression.expression memberaccessexpressionsyntax; if (memberaccessexpression == null) return; var membersymbol = modelextensions.getsymbolinfo(context.semanticmodel, memberaccessexpression).symbol imethodsymbol; if (!membersymbol?.tostring().contains("assert") ?? true) return; //check if we're inside page namespace. //this assert, lets fail it. var diagnostic = diagnostic.create(rule, memberaccessexpression.getloc

i have image found contours on skimage.measure.find_contours() want create mask pixels outside largest closed contour. idea how this? modifying example in documentation: import numpy np import matplotlib.pyplot plt skimage import measure # construct test data x, y = np.ogrid[-np.pi:np.pi:100j, -np.pi:np.pi:100j] r = np.sin(np.exp((np.sin(x)**2 + np.cos(y)**2))) # find contours @ constant value of 0.8 contours = measure.find_contours(r, 0.8) # select largest contiguous contour contour = sorted(contours, key=lambda x: len(x))[-1] # display image , plot contour fig, ax = plt.subplots() ax.imshow(r, interpolation='nearest', cmap=plt.cm.gray) x, y = ax.get_xlim(), ax.get_ylim() ax.step(contour.t[1], contour.t[0], linewidth=2, c='r') ax.set_xlim(x), ax.set_ylim(y) plt.show() here contour in red: but if zoom in, notice contour not @ resolution of pixels. how can create image of same dimensions original pixels outside (i.e. not crossed contour line) maske

i have found in many places c# structures should treated immutable, me understand behavior of following code: public partial class form1 : form { private struct socsearchdomains { public string urlname; public datetime lastrequeststampdate; public int errorscount; public socsearchdomains(string urlname, datetime requeststampdate) { urlname = urlname; lastrequeststampdate = requeststampdate; errorscount = 1; } } private static socsearchdomains[] searchdomain { get; set; } private static socsearchdomains searchdomain1 { get; set; } public form1() { initializecomponent(); searchdomain = new socsearchdomains[1]; searchdomain[0] = new socsearchdomains("192.168.1.81", datetime.now); searchdomain1 = new socsearchdomains("192.168.1.81", datetime.now); } private void button1_click(object sender, eventargs e) {

i have spring service after performing tasks,initiates background async tasks. task have defined component. now, if have use method belonging service initiated thread. can autowire service in thread(component) , work. problem is...the design. brings in kind of circular dependency? how can tackle such issue? servicea-> starts threada component->threada needs call method in servicea. what using @async annotated method described here a non tested example: @service public class myservice { private final resttemplate resttemplate; public string mysyncmethod(){ return "hello world"; } @async public future<string> myasyncmethod() throws interruptedexception { return new asyncresult<>(mysyncmethod()); } }

i have 2 singletone classes i'd inject them fragments, activites, ect., i've inject them each other well. , @ point allways error. public class adverticumchecker implements iadverticumchecker { @inject bannermanager bannermanager; public adverticumchecker(context context) { indexapplication.getapplication().getappcomponent().inject(this); } } public class bannermanager { @inject iadverticumchecker adverticumchecker; public bannermanager(){ indexapplication.getapplication().getappcomponent().inject(this); } } these modules @module public class bannermanagermodule { @singleton @provides bannermanager providebannermanager(){ return new bannermanager(); } } @module public class adverticumcheckermodule { private context context; public adverticumcheckermodule(context context){ this.context = context; } @singleton @provides iadverticumchecker prov

i'm trying serialize object file following: // fill test data arraylist<transaction> transactions = new arraylist<>(); transactions.add(new transaction("internet", "2016-09-20", -28)); transactions.add(new transaction("groceries", "2016-09-20", -26)); //serialize transactions try { // file f = new file("transactions.ser"); // outputstream file = new fileoutputstream(f); // outputstream buffer = new bufferedoutputstream(file); // objectoutput output = new objectoutputstream(buffer); file f = new file("transactions.ser"); fileoutputstream fos = new fileoutputstream(f); objectoutputstream out = new objectoutputstream(fos); out.writeobject(transactions); out.flush(); out.close(); fileinputstream fis = new fileinputstream(f); objectinputstream in = new objectinputstream(fis); object o = in.readobject(); system.out.println(o); }

i have uploaded several spatial datasets ckan repository , stream geojson them. have used datastore api like: datastore_search?resource_id=d6fa3911-ae95-4100-8c4f-78aa388c97c9 ...but returns attributes, not geometry. know geometry available because have put dataset in geojson format , when select explore->preview shows features on map. possible? thanks jim i think can want changing link this: https://yourckanurl/dataset/dataset_id/resource/resource_id/download/anything_you_want.geojson the datastore stores tabular data , not geojson data, trying geojson file resource uploaded ckan won't work. if need database storage of geo data might want @ ckanext-mapstore: https://github.com/geosolutions-it/ckanext-mapstore
