arrays - Sorting in javascript -


this question has answer here:

here's example of array want sort looks like. 

    [ { nums: 'http://s3.amazonaws.com/1375304393109.png',         variant: { name: 'original' } },       { nums: 'http://s3.amazonaws.com/2315456487896.jpg',         variant: { name: 'original' } },       { nums: 'http://s3.amazonaws.com/1375304393109.png',         variant: { name: 'r256x200', size: '256x200' } },       { nums: 'http://s3.amazonaws.com/1375304393091.jpg',         variant: { name: 'r256x200', size: '256x200' } },       { nums: 'http://s3.amazonaws.com/2315456487896.jpg',         variant: { name: 'r512x400', size: '512x400' } },       { nums: 'http://s3.amazonaws.com/1375304393091.jpg',         variant: { name: 'r512x400', size: '512x400' } } ]

i want sort array based on nums(string) key. way want sort array simple: let same numbers group next each other, i.e. 

    [ { nums: 'http://s3.amazonaws.com/1375304393109.png',         variant: { name: 'original' } },       { nums: 'http://s3.amazonaws.com/1375304393109.png',         variant: { name: 'r256x200', size: '256x200' } },       { nums: 'http://s3.amazonaws.com/2315456487896.jpg',         variant: { name: 'original' } },       { nums: 'http://s3.amazonaws.com/2315456487896.jpg',         variant: { name: 'r512x400', size: '512x400' } },       { nums: 'http://s3.amazonaws.com/1375304393091.jpg',         variant: { name: 'r256x200', size: '256x200' } },       { nums: 'http://s3.amazonaws.com/1375304393091.jpg',         variant: { name: 'r512x400', size: '512x400' } } ]

it doesn't have in order, long same numbers group up. fastest way of doing this?

sorry confusion. guess more complicated version of original question. has ideas?

for comparing numbers:

array.sort(function(a,b) { return a.nums - b.nums })

for comparing strings (your case):

 array.sort(function(a,b) { return a.nums.localecompare(b.nums) })

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), ...
