javascript - 170k item array not being processed correctly -


i have fiddle (note: accesses 2k file via jsonp). has small word list @ load consisting of 2 , 3 letter words, loaded array. it's filtered using array.prototype.filter. works.

then page starts downloading enable1 word list (used games featuring word list). @ point, filter functions ends empty array, instead of expected 105 words.

i can confirm that, both before , after,

  • my word list has same starting word (aa) should displayed,
  • the lists have 1091 , 172820 words respectively
  • all words lowercase, , have no surrounding spaces
  • on load, filtering criteria "has 2 letters"
  • there no errors on console
  • there 100mb (25%) increase in fiddle's page's ram usage, system has 35% ram remaining

here's code.

function vm() {       var self = this;      self.characters = ko.observable(2);      self.words = ko.observablearray(document.getelementbyid("words")         .innerhtml.split(/\s+/g).slice(1, -1)         .map(function (word) {         return word.tolowercase();     }));              self.possible = ko.computed(function () {         var letters = self.letters(),             starters = self.startswith(),             enders = self.endswith(),             characters = self.characters();          return self.words().filter(function (word) {             return word.length === parseint(characters);         })             .filter(function (word) {             if (enders === "") return true;              (var = enders.length; >= 0; --i) {                 if (word.slice(-1) === enders[i]) return true;             }              return false;         })/* other filtering code */;      }); }  ko.applybindings(app = new vm);  $.getjson('http://anyorigin.com/get?url=https://scrabble-dictionary-search.googlecode.com/svn-history/r6/trunk/src/main/resources/enable1.txt&callback=?', function(data){     app.words(data.contents.split("\n"));     console.log(app.words().length); });

what causing this? how can work same smaller list?

i think problem when "split" result of ajax call. if log array obtain when split response, see things that: "aa\r".

if use:

app.words(data.contents.split("\r\n"));

instead of:

app.words(data.contents.split("\n"));

that better.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
