i'm transitioning elasticsearch on website , using nest c# .net interface. in writing code index content, can't figure out how map fields individually. suppose have following: var person = new person { id = "1", firstname = "martijn", lastname = "laarman", email = "martijn@gmail.com", posts = "50", yearsofexperience = "26" }; rather indexing entire dataset using: var index = client.index(person); i want index firstname , lastname can searched upon, don't need other fields in index (other id) because take space. can me code map these fields individually? you should add mapping when create index initially. 1 way can using nest attributes on class this: public class person { public string id { get; set; } public string firstname { get; set; } public string lastname { get; set; } [elasticproperty(store=false, index=fieldindexoption.not_analyzed)]

so have created basic show-off type of bot, runs off of skype api , requires skype running in order work properly. have tested bot hosting off of own computer no problem, issue don't want have computer running 24/7. that's why looked @ ovh.com hosting. small $3 vps , host bot off of that. have tried on other servers them (centos/debian) skype running seems quite struggle. in end need (os/program/whatever) bot hosted on ovh vps using 1 of provided operating systems. you have have skype installed on vps, requires have desktop package setup along vnc configure skype. might find article on how setup sevabot, skype bot, useful how setup , install necessary programs, https://github.com/opensourcehacker/sevabot/blob/master/docs/source/ubuntu.rst#id8 . keep in mind if running both skype , extensive java program, cheap vps might not cut it. know vps wasn't able handle skype bot running in large chats, 256mb vps, may have contributed.

i'm having trouble homework question involving using tarjan's algorithm on provided graph find particular scc's graph. while (according professor) have found correct scc's using pseudo-code algorithm found here , of nodes in scc's not share same lowest-link number root node scc. from can gather pseudo-code, because if un-referenced node i (which input node current recursive call algorithm) has arc visited node i + 1 not root node, algorithm sets i s ll = min(i.lowestlink, (i + 1).index) , , (i + 1).index may not equal own lowest-link value anymore. for example (this similar part of graph problem i'm trying solve): if have nodes in n = {a, b, c, d} , , arcs in e = {a ⇒ c, c ⇒ b, c ⇒ d, b ⇒ a, d ⇒ b} , , our root node start algorithm a , then: 1.1) set a.index = 1 (using 1 rather 0), a.ll = 1 , , push a onto stack; a has single arc c , check c ; finding undiscovered, call algorithm on c . 2.1) set c.index = 2 , c.ll = 2 , , push c onto stack; c

i have #include file structures following: #include <core/mod1/file1.hpp> #include <core/mod1/file2.hpp> #include <core/mod1/mod2/.../modn/filen.hpp> and there such includes in each file. example, in file core/mod1/file1.hpp there might #include <core/mod3/file5.hpp> . here core name of library. want use core_new instead of core in entire project, without modifying files (actually lot). have tried add #define core core_new , hoping kind of substitute need: #define core core_new #include <core/mod1/file1.hpp> #include <core/mod1/file2.hpp> #include <core/mod1/mod2/.../modn/filen.hpp> but not it: core/mod1/file1.hpp being included instead of core_new/mod1/file1.hpp . there way achieve it? you want use file system, not c++ compiler. make new directory , copy/link source files on there. change -i option in compiler to use new directory. of course, have new files in the new core directory. way don't need edit sin

i'm using angular js , have problem , have tried many ways , googled related can't work. i'm displaying "name" , "status" in table come json file. want change color of "name" depending on number (string) in "status" column. if "status" -1 "name" should red. best way this. i'm guessing should done inside controller i'm getting json. use ng-class it. for example: <div ng-repeat="item in array" ng-class="{redclass : item.status == -1}"> {{item.name}} </div> .redclass { color: red } this working jsfiddle example. also please see more ngclass .

i writing web application needs take input barcode scanner. currently, system printing barcode adding '\13' (i think carriage return) beginning of value. thus, whenever barcode scanned example firefox, cursor jumps search bar , puts value there rather in text field. i cannot modify printed barcodes themselves. there way prevent barcode changing input field text box search bar? thanks! hitting enter not "jump" different input, instead submit formular in focus located. following keypresses go reloaded page, might end in autofocused search bar or so. to prevent such, install keypress listener on barcode input field , call .preventdefault() on event when enter key. see prevent users submitting form hitting enter details.

i have been trying delete hidden file in directory , accidentally ran command rm -rf .??* delete hidden file more 2 characters. believe deleted file contains connections branches because have master branch. # terminal $ git branch * master the commands ran prior are: $ rm -rf .ds* $ rm -rf .??* $ git add . $ git add -u did delete file of repositories? if so, how retrieve it? if not, why branches used have gone? edit: should add, on github isn't huge problem, rather understand did , undo if possible. you deleted .git directory has repository in, , left data had checked out (which happens master). to retrieve it, restore backup or repo pushed to.

i performing unit tests across large system, made of hundreds of different .java files, forming back-end. in unit tests, should pass variables other methods (calling methods within test method) or test using values created/declared in test method? i'm thinking should come values test method since these unit tests , trying test each method in isolation, i'm not this. need copy functions fetch said data unit tests? generally speaking, should create values in test itself, better isolating system under test. there other kinds of tests, @james mentions, , can use junit integration tests unit tests. @ heart of junit testing unit testing, , proper unit tests isolate system under test. update in response comment: so example if have classes , b: public class { private b b = new b(); public void callb() { b.process(17); b.process(22); } } public class b { public void process(int n) { // stuff n } } your test class b instantiate own b ,

going nuts cell array, because can't rid of it... however, easy 1 guys out here. so here why: have dataset (data) contains 2 variables: (numbers) , b (cell array). unfortunately can't reconstruct problem nevertheless imported table looks this: data=dataset; data.a = [1;1;3;3;3]; data.b = ['a';'a';'buu';'buu';'a']; where data.b of type 5x1 cell can't reconstruct all want unique rows like ans= [1 a;3 buu;3 a] result should in dataset or 2 vectors rows equivalent. but unique([dataa datab],'rows') can't handle cell arrays , can't find anywhere in www how simple convert cell array b vector of strings (does exist?). cell2mat() didn't work me, because of different word length ('a' vs 'buu'). though, 2 things love learn: making 5x1 cell string vector , find unique rows out of numbers , strings (or cells). thank much! cheers dominik the problem a , b fields of different typ

i working spring mvc controller. have 1 of controller datacontroller . i thinking add httpservletrequest injectable @ top of datacontroller class using @inject . @controller public class datacontroller { @inject httpservletrequest request; // .. code here @requestmapping(value = "process", method = requestmethod.get) public @responsebody dataresponse processtask(@requestparam("workflow") final string workflow) { string ipaddress = request.getremoteaddr(); system.out.println(ipaddress); } so question - right way use @inject ? have never used @inject before trying learn whether way doing right or not? since everytime, making call processtask method, need grab ipaddress whoever calling processtask method. in terms of acquiring httpservletrequest : semantically speaking, wrong. reason : httpservletrequest object created when users send requests , destroyed once requested user action completed. can s
