i trying deal following situation : => homepage simple form => page results form additional search criterias what did : => 2 differents form components actions & reducers => page result gets information both forms/components the problem have : => have lot of code same. actions , reducers same things both forms (api call etc.) => page results needs fed 2 different sources make code inelegant point of view i quite beginner , think there must elegant way of handling such case seems quite common. maybe solution obvious indulgent... learning :) thanks lot help,

so i've tried: import random r t = {'va1':r.randint(0,50),'va2':r.randint(0,15),'va3':r.randint(0,10)} n=15 _ in range(n): new_dict = {k:t k in range(n)} print(new_dict) that gave me dictionary of random dictionaries t, weren't unique, dictionary full of 1 version of t. what i'm looking dictionary keys 1,2,3...n , values dictionary t. need t different each iteration of loop. thanks reading python doesn't re-run dictionary literal because reference it. t nothing more single dictionary created @ start. the solution create new dictionary scratch in dictionary comprehension (both key , value expressions executed anew each iteration): n=15 new_dict = {k: {'va1':r.randint(0,50),'va2':r.randint(0,15),'va3':r.randint(0,10)} k in range(n)} print(new_dict) you may want put creating nested dictionary function: def random_values_dict(): return {'va1':r.randint(0,50),'va2':r.randin

i'd understand why 2 functions tf.image.crop_to_bounding_box , tf.image.pad_to_bounding_box exists, since behaviour of these 2 functions can done respectively tf.slice , tf.pad . they not easier understand, , scope narrow since accept 3d , 4d tensors. furthermore, tend slower in terms of time of execution. is there miss here ? mostly use them tf.image.* easiness of use. both crop_to_bounding_box , pad_to_bounding_box use slice , pad underneath, add checkings , constraints make sure don't spend hours trying debug slice/pad indices , offsets.

in f#, nominative or structural? , answer said can trick f# work structurally-typed language via exotic mechanisms. how can so? the "exotic mechanism" previous answer refers statically resolved type parameters . lets write functions take object of type has specific member. example, can write sayhello function work object has name member of type string : let inline sayhello (any : ^t) = let name = (^t : (member name : string) any) printfn "hello %s" name this work 2 types nominally unrelated: type person(name:string) = member x.name = name type animal(name:string) = member x.name = name sayhello (person("tomas")) sayhello (animal("bunny")) that said, f# nominally typed language , relying on static member constraints unidiomatic. make code bad , you'll hit limitations of mechanism. nice feature some limited use cases, it's not primary abstraction mechanism in f#.

i'm trying end-of-degree project in c++ visual studio , i'm stucked several weeks. when try build project, vs returns lots of errors , stops build @ count of 100. i'm trying simple hello world(msdn example) doesn't work. installed/uninstalled/reinstalled/repaired vs , components several times no success. i'm bit desperate this, appreciate kind of help. here captures of errors given , code of program: http://imgur.com/a/hw1vp edit: i'm added output information , inside of cmath, 1 of libraries causes errors: http://imgur.com/a/n8ftm thank helping, alex.

i'm reading in file , replacing text, writing new file, line line. use following code read , write file. there no issues files cp1252 , utf-8 encoded, when try reading in file encoded in "ucs-2 le bom" file saved starts bom characters , contains whole lot of whitespace. know due encoding don't know if need read in differently or save differently. also, know set encoding when read file in, how can handle differntly-encoded files without knowing 1 coming. have no control on file until hits java code. appreciated, thank you. fileinputstream sourcefileinputstream = new fileinputstream(sourcefile); datainputstream sourcedatainputstream = new datainputstream(sourcefileinputstream); bufferedreader sourcebufferedreader = new bufferedreader( new inputstreamreader(sourcedatainputstream)); filewriter targetfilewriter = new filewriter(new file(targetfilelocation)); bufferedwriter targetbufferedwriter = new buffe

if run small function below, you'll see below picture. smaller-sized " here " fixed around curve. larger-sized "here" moving if run function multiple times ( see r code further below ). my question how can have size of fixed "here" text() become equal size of moving text() only when 2 pieces of text fall on top of each other? please see annotated r code below. here = function(){ curve(dnorm(x), -4, 4) x.on.curve = seq(-4, 4, len = 21) # x.values fixed text y.on.curve = dnorm(x.on.curve) # y.values fixed text xx <- sample(x = seq(-4, 4, len = 21), size = 1) # x.values moving text yy <- dnorm(xx) # y.values moving text text(x.on.curve, y.on.curve, 'here') ## whenever x.values of fixed 'here' # matches x.value of moving 'here' # in below "text()", change cex = 2, else cex = 1

this question has answer here: what constitutes valid state “moved from” object in c++11? 2 answers does moving leave object in usable state? 2 answers what can moved-from object? 2 answers reusing moved container? 3 answers i have been trying understand std::move. this doc describes nicely. says in example section "..... while bar loses value, , in valid unspecified state .....". lots of other docs use terminology in same context. also, found lots of answers on stackoverflow related it. this same question. not talk "what being unspecified means?" so questions are? what bei

we have simple shopify store using free "meta fields editor" add simple custom field integer value each of products. products have meta value of 3, others 2 or 1. many have no meta value @ all. able display products in search results, meta field value entered each product in descending order (weighted ordering). however, despite ability set meta values , display them in search results , collections pages, shopify not make easy order or sort products custom meta field. in search results page able call custom meta value using {{item.metafields.important.important}} far have tried order products using method {% assign products = collection.products | sort: 'item.metafields.important.important' %} {% product in products %} {{ product.title }} {% endfor %} but results in null results. insight can give me in how display products in order of custom field appreciated! after attempting find liquid solution able solve problem using custom metafields ,

if have following flux<string> flux1 = ... flux<string> flux2 = ... flux<string> mergedflux = flux1.merge(flux2); how/when/why mergedflux complete? the principle of least surprise might suggest complete when of merged fluxes have completed. however, not have witnesses. the semantics of merge attempt exhaustively replay interleaved emissions of both flux single flux . consequence, merged flux completes when both sources complete. contrast operator zip aims @ producing many pairs possible taking 1 element each source. such completes when of sources completes, because on cannot produce pairs anymore.

in drupal 8, when trying render nested value starts "#", such #default_value, symfony freaking out because of unescaped # drupal names it's array structures with. there way escape "#"? i tried formatting raw , using | e filter without luck. <h1>test</h1> <div>{{ form.field_perf_goal2_main.widget.0 }}</div> <div> {{ form.field_perf_goal2_main.widget.0.#default_value}} </div> {{ kint() }} in above example form.field_perf_goal2_main.widget.0 yields correct result (when kinted). form.field_perf_goal2_main.widget.0.#default_value throws error of unexpected character. far know there isn't escape character feature in twig. thanks! @pig-ball. rendering such solved issue. {{ form.field_perf_goal2_main.widget.0['#default_value'] }}
