is possible reference types within c# project in xml schema file? validation , intelli-sense mean... lets have following: namespace example { class mytype { int test = 0; } } how reference example namespace within schema file can use mytype element type? not directly. there's sort of 2 ways can though. the first mark class serializable , use xmlserializer serialize xml. in conjunction this, can use xsd.exe create schema class, , that used type in (other) schema. xmlserializer used serialize , deserialize to/from type. on related note, if have method want capture in in xml (as opposed data types or structures), can extend xslt c# (or vb.net, or javascript) code. msdn has more documentation on how that, basic idea being use xsltargumentlist , addextensionobject add method. it's possible directly in xslt using msxsl:script (see here more information on that).

vine.co allows videos @ 6 seconds. users upload phones. wonder if can done browsers. thanks. (i rely on node.js) it depends how want perform upload. option 1 - if movie uploaded streaming server in, example, rtsp or rtmp, server can elect drop movie based on duration, determined during upload. accurate , efficient option requires uploader able stream file , server accept stream media server. option 2 - if movie uploaded file transfer easiest limit movie file size. size can determined heuristics if know bit rate. example, @ 500kbps you'd expect 6 second movie weigh approximately 375kb, might limit uploads 450kb , figure exact boundary while inspecting file on server side. work must know in advance movie's average bit rate. option 3 - yet option, based on movie metadata: depending on movie format might able determine upfront movie's duration inspecting file headers. in mp4, example, if mov atom @ beginning of file can tell upfront what's movie'...

alright, have input looks this: 1 6 2 3 4 1 8 3 4 7 2 1st # represents number of dimensions of array 2nd # = # of elements in array. 3rd # = rows of array (index) 4th # = columns write segment of code print out indices of array. example, output of 2nd line should like: 00 01 02 03 10 11 12 13 20 21 22 23 i hope makes sense. understand how write code without recursion. it's matter of loops , cout statements can't figure out how use recursion. simplest case, 1-dimensional array, we'd write out code second simplest case have use recursion work next 3rd , 4th etc cases. one way recursively write function takes number p , string of numbers ones in input file. function prints out results describe, uses p prefix. f(99, 1 4) print: 990 991 992 993 is enough of hint, or should go little farther?

so given function 65536 n 2 + 128 n log 2 n and way o(n 2 log 2 n) if c = 65664, n0 = 2 n ≥ 2 since c1 = 65536 n1 = 2 when 65536 ≤ c1*n 2 and c2 = 128 n2 = 1 when 128 ≤ c2*n but number i've chosen constant seems bit high, there way check this? o(65536 n 2 + 128 n log 2 n) same o(n 2 + n log 2 n) since can ignore multiplicative constants. o(n 2 + n log 2 n) equal o(n 2 ) since n 2 grows faster n log 2 n. also, way, base of logarithms doesn't matter in big-o analysis. logarithms grow @ same rate. after all, log 2 n = log n / log 2, , multiplicative constants can factored out. can log n instead of log 2 n. caveat: technically, true statement 65536 n 2 + 128 n log 2 n &in; o(n 2 log 2 n) because big-o gives an upper bound, not strict one. o(n 2 ) lower upper bound, if makes sense. that said, should not have come o(n 2 log 2 n). merely result of accidentally turning addition multiplication. rule of thumb, if have multiple things added in...

actually have multiple .txt files in .gz file. extract .txt files .gz file... example: gz_extract = zlib::gzipreader.open("sample.gz") gz_extract.each |extract| print extract end the above code prints whatever present in .gz file want un-gzip .txt files. hope ppl understood question.... actually have multiple .txt files in .gz file. extract .txt files .gz file. gzip cannot contain multiple files together. works 1 file. if want compress multiple files, first need tar them together, , gzip resulting .tar file, not appear case file using. if can read contents of sample.gz code provided, further proof have 1 file inside. can try gunzip sample.gz command-line again prove contains 1 file. edit: if want code output uncompressed .txt file: output_file = file.open('sample.txt', 'w') gz_extract = zlib::gzipreader.open("sample.gz") gz_extract.each_line |extract| output_file.write(extract) end output_file.close

i have large, sparse binary matrix (roughly 39,000 x 14,000; rows have single "1" entry). i'd cluster similar rows together, initial plan takes long complete: d <- dist(inputmatrix, method="binary") hc <- hclust(d, method="complete") the first step doesn't finish, i'm not sure how second step fare. approaches efficiently grouping similar rows of large, sparse, binary matrix in r? i've written rcpp code , r code works out binary/jaccard distance of binary matrix approx. 80x faster dist(x, method = "binary") . converts input matrix raw matrix transpose of input (so bit patterns in correct order internally). used in c++ code handles data 64 bit unsigned integers speed. jaccard distance of 2 vectors x , y equal x ^ y / (x | y) ^ xor operator. hamming weight calculation used count number of bits set if result of xor or or non-zero. i've put code on github @ https://github.com/niknakk/binarydist/ , rep...
