is correct way prototype inheritance , property 'stealing??'/inheritance. want inherit properties person constructor + methods. function product(name, price) { this.name = name; this.price = price; } product.prototype.tellme = function() { console.log('name = ' + this.name + ', price = ' + this.price); } function food(name, price, category) { product.call(this, name, price); this.category = category; } food.prototype = object.create(product.prototype); food.prototype.constructor = food; var b = new food('name', 123, 'category'); console.log(b); b.tellme(); var = new product('name2', 321); console.log(a); i appreciate if give me example. thanks! latest javascript standard, ecma6, enables perform inheritance writing class in similar fashion java oop. developer highly familiar java oop, have found approach easy understand , adapt. @ attached snippet code rewritten. hope helps.

this theoretical question , not reproducible. apologies in advance. i have n dataframes in global environment: df_1, df_2 ... df_n and want operate on these dataframes within function output new dataframes global environment. want function takes name of dataframe , brings function environment operated on, instance: myfun <- function(name){ ... need bring in df1, operate on it, , make new df}) once have function, i'll use lapply apply character string of dataframes need operate on. my question is, how use character string of dataframe names reference dataframes stored in global environment (i.e. - df1, df2 ... dfn) can create new dataframes these referenced ones?

i have blog post set of images enlarged on hover. problem when enlarge element , overlaps other image later in page render order next image on top of enlarged one. the easy way stop give kind of z-index on :hover pseudo selector. have pesky problem when after stop hovering image next 1 on top of fraction of second. you can see behaviour in this imgur album or on jsfiddle (hover first image) in short have following css hovering effect: .photo-exp { position: relative; transition: .4s ease-in-out; /* properties deleted have no connection hovering effect */ } .photo-exp:hover { transform: scale(1.7); z-index : 10; } it easy have same effect javascript , settimeout function. but avoid javascript solution , have css workaround change z-index in time after hovering ends. i tried css transition not working tried eddit this snippet not working in way wanted. you need assign new transition-delay property, , remove hover begins. way z-index can persist time af

i'd appreciate figuring out how zip file unzip. app.post("/api/upload/", upload.single("recfile"), function(req, res){ console.log("saving new zipped shapefile"); console.log(req.file); var tmp_path = tostring(req.file.path; var target_path = "test/" + req.file.originalname; var dest = fs.createwritestream(target_path); var src = fs.createreadstream(tmp_path); src.pipe(unzip.extract({path: dest})); // tojson.fromshpfile(dest).pipe(dest); }); the files upload , save test folder i'm created, receive error regarding unzip code. error: enoent: no such file or directory, open '[object undefined]' i think since code asynchronous, isn't recognizing uploaded file in directory time code runs. promise work in case?

i have small program command line interface uses number of python classes thorough implementations. want scrap command line interface , wrap app within django app, i'm learning django , i'm unfamiliar conventions. i have number of classes, in-memory storage structures, getters/setters etc , i'd convert them django models can persist them database , interact them around django app. there general approach doing this? should inherit django.db.models.model class in existing classes , set them direct interaction? or there better, more general/conventional way this? i able use of code in other apps, not necesarilly django ones, don't want modify existing classes in way make them work django. thought of creating models separately , sort of middle-man class manage interaction of actual in-memory class django model class, seems more places have make changes when extend/modify code. thanks ahead of time... personally, modify existing classes extend models.

so let's have project a, requires dependencies. , have project b, has project 1 of dependencies. have following code in project b's build.gradle: project b's build.gradle: dependencies { compile files("projecta_dir/build/libs/projecta.jar") } however, since gradle not include project a's dependencies in projecta.jar default. wondering if there's way let project b compile project without creating fatjar project a. the jar file doesn't contain transitive dependencies , doesn't have pom file describes dependencies used module. it means that, if importing jar file using compile files you have specify dependencies in project . you should use maven repository , private or public, avoid issue. in case, gradle downloads dependencies using pom file contains dependencies list.

using typical _id column , joining tables , selecting columns when creating cursor, result in cursor contains multiple _id columns. to access specific _id column require using actual offset, opposed column name. using hard coded offsets can problematic, makes code harder read , maintain. for example 2 tables shops , aisles per shops table has columns _id shopname aisles has columns _id aisleshoplink aislename then might want cursor containing aisle , associated shop (aisleshoplink holding _id of respective shop aisle in). using select * aisles left join shops on aisleshoplink = shops._id will result in cursor has columns _id (aisle's _id offset=0) aisleshoplink (value respective shop's _id, offset = 1) aislename (offset =2) _id (the shop's _id, should match aisleshoplink, offset = 3) shopname (offset =4) the resultant cursor has nothing distinguish _id columns other offset. can't prefix table name in sql. i.e cursor

i'm building app similar functionality instagram, , i'm not sure how best structure data tableviews , collectionviews. let's go on views first. newsfeed vc own array of posts (newest information) group vc own array of posts (group specific information there ~30 different groups) search vc own array of posts (search result specific) expanded vc displays post in full screen the problem user can like/comment on post in group/search vc might in newsfeed vc or vice versa. currently passing index vc vc , modifying data in array. has lead few problem end looping on other arrays sync likes/comments , have refresh tableview user change in present locally. i'm wondering if there more efficient/logical way store of data. need group data separate newsfeed data, , user can change group whenever want see other posts. i've never used core data, i'm open anything. ideally, i'd able store of information in 1 place single copy of every post. right if post
