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?

i have search method in user.rb model def self.search(query) where("description ?", "%#{query}%") end but search case sensitive. want make case insensitive. how do that? i'm hoping it's quick fix. thanks because using postgresql: def self.search(query) where("description ilike ?", "%#{query}%") end just use ilike instead of like . like/ilike documentation if want use =, both sides either upper or lower

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

i'm trying use simple angular function in laravel 5 project , keep getting error: angular not defined i have tried move angular.min.js top making first js script on index page still doesn't work. this code: pastebin code it outputs {{name}} , not actual string controller! what doing wrong? i have seen issue before. in case due incorrect relative reference using. not expert in matter recommend try different combinations , see if helps. see js folder placed in website hierarchy ex. src="js/angular.min.js" or src="../js/angular.min.js"

i want create external table in hive takes input multiple databases. eg: want create bigtable (a,b,c,d,e,f) sources coming db1.table1(a,b) , db2.table2(c,d,e,f,a) also, bigtable has update when db1.table1 , db2.table2 updated. side notes: the source tables updated on daily basis. field "a" common field if want perform join on tables. suggestions open scenario there no common fields between sources. yes. think can create view on top of union of tables. create view veie_test select * union select * b ... on.

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

here's jsfiddle has a simple table internal cms: <table class="rotated-text"> <thead> <tr> <th>property</th> <th>san francisco, ca</th> <th>new york, ny</th> <th>washington, dc</th> <th>charlottesville, va</th> </tr> </thead> <tbody> <tr> <td>days of sunshine</td> <td>260</td> <td>200</td> <td>210</td> <td>220</td> </tr> </tbody> </table> i'd rotate text in first element 45 degrees counterclockwise, without bringing along background. i'm hoping can without changing html -- applying css. result should similar this: is possible? the closest come dispense borders , border-spacing in table. giving borders style need may unattainable. lines between th s simulated underline. .rotate
