i have view container containing multiple view tags using flexdirection: 'row' property. however, issue arises when have many elements in container view . reasons, view components inside container don't wrap , overflow outside container. see image here you can see view container has border, contents flowing outside of it. my render function render() { let test = ["acute pain","acute pain","acute pain","acute","acute","acute","acute"] let tagnames = test.map((tagname, index) => { return ( <view style={{backgroundcolor: '#1bb393', padding: 3, borderradius: 5, marginright: 5}}> <text style={{color: 'white', fontfamily: 'facit'}}>{tagname}</text> </view> ) }) return ( <view style={{flexdirection: 'row', flex: 1, borderwidth: 1}}>{tagnames}</view> ) }

using c# have existing interface wish split read , write interfaces still keep original. best way? i make 3 independent interfaces: interface iexistingreadwrite{ int width {get; set;} } interface iread{ int width {get;} } interface iwrite{ int width {set;} } or make iexistingreadwrite inheret iread , iwrite, clearer other coders when @ iexistingreadwrite there segregated iread , iwrite interfaces available too... interface iexistingreadwrite: iread, iwrite{ new int width {get; set;} } interface iread{ int width {get;} } interface iwrite{ int width {set;} } but i've had use 'new' on iexistingreadwrite shadow properties in iread , iwrite otherwise warnings ambiguity occur. shadowing not intention iexistingreadwrite 'pass work on' interfaces inhereted define new property (so there no opportunity there being seperate implementations each of seperate interfaces occuring). there better way. it looks corak has best answer far...

first, installed versions of python / various modules: python: 2.7.1 numpy: 1.13.1 scipy: 0.19.1 py2exe: 0.6.9 the modules installed wheels available here: http://www.lfd.uci.edu/~gohlke/pythonlibs/ i have python code have written compiling single, stand-alone executable "future-proof" it, , allow run on other pc's might not have same modules installed do. having same issue described in following posts: omp warning when numpy 1.9.2+mkl packaged py2exe omp warning when numpy 1.8.0 packaged py2exe the news is, omp warning message not negatively affecting code. however, either resolve issue causing warning message, or suppress warning messages, since not affect performance of code, might confuse / annoy user. can provide advice? sounds previous posters have tried lot of things already, figured might time fresh look. there part of numpy can modify doesn't make reference omp, since i'm not using (at least, i'm not

i learning use netbeans , gulp develop in wordpress, following great tutorial @ lynda.com. have sass set compile partial .scss files style.css file project, compiles fine. however, when attempt add padding around specific class, css not take effect. can see code added in style.css file here: site-content { padding: 2em; } and included in style sheet page; when webpage rendered, no padding appears (as in tutorial). i thought maybe other css overriding padding, , found this: <link rel='stylesheet' id='casse_dev-style-css' href='//192.168.0.26:8080/wp-content/themes/casse_dev/style.css?ver=4.8' type='text/css' media='all' /> <link rel='https://api.w.org/' href='//192.168.0.26:8080/wp-json/' /> <link rel="edituri" type="application/rsd+xml" title="rsd" href="//192.168.0.26:8080/xmlrpc.php?rsd" /> <link rel="wlwmanifest" type="application/wlw

so here detail description. have keras functional model 2 layers outputs x1 , x2. x1 = dense(1,activation='relu')(prev_inp1) x2 = dense(2,activation='relu')(prev_inp2) i need use these x1 , x2, merge/add them , come weighted loss function in attached image. propagate 'same loss' both branches. alpha flexible vary iterations it seems propagating "same loss" both branches not take effect, unless alpha dependent on both branches. if alpha not variable depending on both branches, part of loss constant 1 branch. so, in case, compile model 2 losses separate , add weights compile method: model.compile(optmizer='someoptimizer',loss=[loss1,loss2],loss_weights=[alpha,1-alpha]) compile again when need alpha change. but if indeed alpha dependent on both branches, need concatenate results , calculate alpha's value: singleout = concatenate()([x1,x2]) and custom loss function: def weightedloss(ytrue,ypred): x1true =

we have form user enters firstname, lastname , address. users entering firstname/lastname website. ex: www.google.com, google.com or other spam site. is there way validate these kind of inputs? note : don't want replace or avoid special characters causing issues when people enter name in different language other english. those "some users" hackers penetration testing web site. use regular expression filter out fake names match pattern. name start http:// or www. ? name end in .com or .net ? if so, don't allow users enter name. if google "regular expression url matching", should plenty of examples of regular expressions match url strings. need validation not allow names match url regex, , conversely, allow names don't match.

i'm not sure if best use list or dictionary algorithm. assuming use dictionary, want create dictionary of size x , randomly assign each element y index values of dictionary itself. meaning take dictionary of size 5, , assign each of 5 elements 2 index values ranging between 1-5. the constraints index value can not assigned own index, 2nd index can assigned values 1,3,4,5; , y must less x, in order prevent assigning duplicate index values same index. what have far being done list rather dictionary, i'm not sure if best method. i'd keep algorithm running @ 0(n) speed well, if size of list/dictionary huge. either way, i'm at. so, make x list of size 5. set y equal 3, meaning want each of 5 elements contain 3 index values. in for-loop create list excluding index value i'm assigning values to. x = range(5)[::1] # [0, 1, 2, 3, 4] print(x) y = 3 assigned = [] k in range(0, len(x)): xexcluded = [x i,x in enumerate(x) if i!=k] # if k==3 [0, 1, 2,
