i have requirement of ranking keywords in document. have 1 document, dont know how tf-idf help. rank keywords based on proximity , relevance document, know if use term vector this, , if yes how? thanks in general, obtain "proximity" between several document using terms or terms using several documents, use latent semantic space --- latent semantic analysis here . however given have 1 document, cannot that, because have no reference. it's trying find how many standard deviations away mean value of interest located, have single number. 1 way solve this, obtain new data, if topics of document isn't obscure try scraping information off internet. if isn't looking for, perhaps may explain problem more desired outcome rather method think may applicable here. cheers

i using angularfire $add method add basic js objects of form {id:integer,name:name} now, if want update particular item (which has firebase-assigned key "-jeca_f70efhbki5js7j" or something, impression should use $save method. here how trying this: $scope.chosencolors = $firebase(mychosencolorsref); $scope.updatecolor = function(data){ //data js object {id:'id',name:'name'} if($scope.chosencolors.$getindex().length>0){ var keys = $scope.chosencolors.$getindex(); keys.foreach(function(key, i) { if($scope.chosencolors[key].id!=data.id){//if id matches want update name $scope.chosencolors[key] = {id:data.id,name:data.name} $scope.chosencolors.$save[key]; return; } }); }else{ $scope.chosencolors.$add(data); } but doesn't appear have effect on firebase...any ideas doing wrong? firstly, should call $save method in

i've created class building linked list. class declaration follows: class linkedlist { private: int data; linkedlist *next; static int count; public: linkedlist(void); ~linkedlist(void); int insert(int arg); int remove(int arg); bool find(int arg); }; how can make sure nodes of linked list deleted ? destructor made responsible deleting 1 node. used make linked list never thought clearing memory. the naive implementation ~linkedlist() {delete next;} will right thing - delete call destructor on next element, delete 1 following it, , on, delete whole list. however, means destructors called recursively, deleting long list cause stack overflow. iteration might better: ~linkedlist() { while (linkedlist * head = next) { next = head->next; head->next = nullptr; delete head; } } as noted in comments, might more appropriate have separate list , node classes, list r

using vert.x in java, use worker module ( ebean orm ) in standard module(event loop) declaring "include" in mod.json or better setting ebean module system-module. will block event loop , should use eventbus instead? if module has blocking code (using blocking apis or doing lot of computation), should not use on event-loop. golden rule: never block event-loop. otherwise application won't responsive. even if code in module non-blocking, i'd try use standard module way: can reuse different languages easier , if decide change internal implementation details in future, won't break user-code easy have json interface via event-bus.

i hear sound program supposedly comes android called "stagefright" needed in order play audio files command-line of terminal emulator. 1 source heard of here: how use stagefright command line? problem --- checked pretty on android device (aesus nexus 7) , isn't there.

i managed use proxy server selenium chrome using code below: chromedriver = "c:/seltests/chromedriver" os.environ["webdriver.chrome.driver"] = chromedriver chrome_options = webdriver.chromeoptions() chrome_options.add_argument('--proxy-server=141.0.175.141:443') driver = webdriver.chrome(chrome_options=chrome_options) however, know if possible change proxy new 1 during run-time. or if there other way of doing allows me to. i'm thinking using code above have have browser close re-open start new session , use proxy? please :) you have re-launch browser instance in order achieve this. wherever want change proxy insert following code: driver.quit() chrome_options = webdriver.chromeoptions() chrome_options.add_argument('--proxy-server=<new proxy>') driver = webdriver.chrome(chrome_options=chrome_options) this close current browser , launch new 1 new proxy.

am trying enable client node ssl encryption in dse server. my cqlshrc file looks below [connection] hostname = 127.0.0.1 port = 9160 factory = cqlshlib.ssl.ssl_transport_factory [ssl] certfile = /path/to/dse_node0.cer validate = true ;; optional, true default. [certfiles] ;; optional section, overrides default certfile in [ssl] section. 1.2.3.4 = /path/to/dse_node0.cer when tried login cqlsh shell getting below error connection error: not connect 127.0.0.1:9160 there several possible causes hope 1 of these solutions helpful. 1) certificate in ssl section not same (derived from) keystore specified in cassandra.yaml file. solution: generate certificate keystore used in cassandra.yaml file , place in location pointed in cqlshrc file. 2) certificate file or keystore changed after starting node. cassandra loads copy of certificate when starts up. solution: restart node. 3) in certfiles section 127.0.0.1 over-ridden wrong certificate solution: use

i'm trying code filters text processor. receive socket files have process line line. each line need apply filters , in specific order. example, 1 file i'll use filter 1, filter 2, filter 3 , after filter 2 again. my question best way run filters in specific order , how define them can add more filters without have change lot of code? best way ensure high speed executing filters line line? i use chain of responsibility. assume filter says either true (include/accept line), or false (do not include i.e. reject line). so chain several filters in chain, if filter 1 returns true , pass line next filter 2 (and on). otherwise (if filter chain says false ), reject line and don't go checking next filter chain. chain of responsibility pattern what best way ensure high speed executing filters line line? this depends on many factors so hard give response on it.

i have string taken user, saved "variable" named num . now, load first character string register further processing. looked like mov rax, [num] cmp rax, '5' je character_equal_five i got problems in later part started debugging 1 line , input "522314" figured out rax register's value 2000, while should five's ascii code. doing xor rax, rax mov rax, [num] did not either. finaly done this mov al, [num] and successful reliable results. question is: why happen? why can't use bigger register task?
