i determine whether or not request rest api has been made jquery $.ajax() method. before answering question 1 of obvious answers of adding boolean data sent server, or adding header, not want this... obviously can achieved so: $.ajax({ data: { sentviaajax: 'true' } }); however, various reasons boolean/additional header remain hidden code. therefore, know jquery send other data in particular form server when makes request? i have tried printing out $_request array not contain other data sent. there unique headers out for? if so, reliable, in, there? jquery sends following header on non-cross-domain ajax requests: x-requested-with: xmlhttprequest so header on request.

i'm trying habit of writing unit tests, i've written few before they've been quite basic...i'd start making move tdd want improve quality of code (design , structure) - reducing coupling, while @ same time reduce number of regressions slip through testable build. i have taken relatively simple project work on begin with. resultant program watches folder , acts on files within folder. here typical example of code extracted project: private string restoreextension(string file) { var unknownfile = path.getfilename(file); var ignoredir = path.getdirectoryname(file) + "\\unknown"; string newfile; //we need library determining mime if (checklibrary("urlmon.dll")) { addlogline("attempting restore file extension"); var mime = getmimetype(bufferfile(file, 256)); var extension = fileextensions.findextension(mime); if (!string.isnullorempty(

looking on how calculate rsa secret key in bash script 'd' when p, q & e given. although know query has come before, seem find theoretical advice on calculation of rsa private key when p, q & e given. i trying put calculation in bash script , explanation on calculations possible in bash (with expr or bc) i found site advised following; (with 't' being totient of p*q, or rather totient of 'n') d=$(echo "((2 * $t) + 1) / $e" | bc) but seems work on specific case , did not provide correct output when trying on different cases. any on how write bash formula calculation ? from defition of rsa |e*d| = 1 (mod fi(p*q)) where fi(n) euler function so need calculate inversion of e in modulo. don't forget check if gcd(e,fi(p*q))=1 or may not find inversion of e in given modulo. you can achieve using extended euclidean algorithm. there lot of pseudocodes on web. need more help?

this question has answer here: what point of making singleton instance volatile while using double lock? 5 answers i came across singleton class {lazy initialization}. code below // singleton reference class private static volatile fileproperties instance = null; public static fileproperties getinstance() { if (instance == null) { synchronized (fileproperties.class) { if (instance == null) { instance = new fileproperties(); } } } return instance; } my question benefit getting making instance volatile since taking care of thread safety synchronized. there benefit of volatile in scenario ? that because double-checked locking without volatile not thread-safe in java. the simplest way make thread-safe lazy-

this question has answer here: difference between date(datestring) , new date(datestring) 9 answers suppose define variable this var today = date(); console.log(today.getmonth()); // throw error while other class error class call methods without new operator. function factorial(x) { if(x <= 1) throw error("x must not negative"); return x*factorial(x-1); } also wrapper objects (number, boolean, string) can call methods without new operator. so, class require new operator or object creation technique before calling methods. edit: date() string type, should call methods without creating objects. because string type behave if objects. why not? edit 2 : think core function cannot same new date() other functions ( array(), string(), error() etc). so, it's hidden feature of language or ecmascript mistake. ecmascript language sp

"large" array, mean array has perhaps 500 elements each element having 100 fields. i have thousands of users doing process several times / minute. first, brief intro session handling in php: when open session, cookie created contains id of session, , sent client. php use path defined in session.save_path save file using id filename ( reference ). what mean in case? means you'll creating additional bottleneck (disk i/o 1 of slowest things in setups) because you'll writing/reading files time. database servers have tons of code handle kind of latency, might beneficial use table in database has serialized array string, keyed id in $_session .

i'm compiling code written gcc, in visual c++ 2012. i'm getting warnings thrown enum value truncation following enum (due value being outside range of int): enum tile_flags { tile_flag_inner_flame= 0x10000000ull, tile_flag_constricted= 0x20000000ull, tile_flag_mimic_inept 0x2000000000ull tile_flag_mimic 0x4000000000ull tile_flag_mimic_raven 0x6000000000ull tile_flag_mimic_mask 0x6000000000ull } when compiling x86, appear msvc truncates enum values fit in 32bits. however, no truncation occurs in gcc. happening on gcc? , how can make work msvc? from n3485, § 7.2/6: for enumeration underlying type not fixed, underlying type integral type can represent enumerator values defined in enumeration. if no integral type can represent enumerator values, enumeration ill-formed. implementation-defined integral type used underlying type except underlying type shall not larger int unless value of enumerator cannot fit in int or unsigned int. if

i have project multiple .cpp , .h files. have file called globals.h included in .cpp files. when compiling file use -d options. these options affect files not globals.h. in makefile had use same -d options when compiling every file. of course when removing options "undefined" errors arise. this means every time change 1 of these options have recompile whole project. there way let me compile globals.h these options? this part makefile: lines create globals.o : globals.o : $(globalslib) $(globalsinc) g++ -c -wall $(codedefined) $(userdefined) $(globalslib) -std=c++0x -o globals.o $(globalslib) , $(globalsinc) paths files globals.h , globals.cpp $(codedefined) , $(userdefined) -u , -d options code creating .o file: nt_fft_decomp.o : $(globalslib) $(globalsinc) $(nt_decomplib) $(nt_decompinc) g++ -c -wall $(codedefined) $(userdefined) $(nt_decomplib) -std=c++0x -o nt_fft_decomp.o (nt_decomplib) $(nt_decompinc) paths files. notice had add sa

it seems best use &amp; escape , instead of typing ampersand (&). however, should using x/html character entity references dashes , other common typographical characters when writing blog posts on cmss wordpress or hard-coding websites hand? for example: &ndash; en dash (–) &mdash; em dash (—) what risk if not? why hyphen (-) never written &#45; typed directly keyboard in html? (assuming hyphen, , not minus sign .) the w3c released official response when use , when not use character escapes can find here . group in charge of html specification, think it's best follow advice. from section "when use escapes" syntax characters. there 3 characters should appear in content escapes, not interact syntax of markup. these part of language documents based on xml , html. &lt; (<) &gt; (>) &amp; (&) they mention using characters might not supported in current encoding.

i have project use stdafx.h precompile header. means cpp file must contain #include "stdafx.h" first include. however, in a.h, need include "afxinet.h", compiler complain this "error c1189: #error : windows.h included. mfc apps must not #include "windows.h"" this because "afxinet.h" complains when windows.h included, "stdafx.h" have windows.h included , present first include in a.cpp. this implies need somehow have "afxinet.h" included in front of "stdafx.h", "stdafx.h" precompile header , needs present first include... how can resove dilemma? if project uses mfc, should include headers in stdafx.h , not use windows.h (as included mfc); , if include windows.h, cannot use mfc. afxinet.h part of mfc, so, guess, should either (1) replace windows.h afxwin.h , "use mfc" in settings (2) don't use mfc wrappers wininet, use functions wininet.h

if have data.frame(sum_clus) 600 columns(variables) , 10 rows have no na's , numeric values, how can create 5 new variables give me column names of top 5 variables in row? for eg. max <- apply(sum_clus ,1, max) for(ii in 1:10) sum_clus$max[ii] <- colnames(sum_clus)[which(sum_clus[ii , ] == sum_clus[ii, sum_clus[ii,] == max[ii]])] this above code helped me create variable sum_clus$max gives me column name of max variable in each row. similarly, how can 5 such variables give me column names of top 5 variables? sum_clus$max, sum_clus$second_but_max, , on.. thanks in advance! here's similar solution, using (i) loop instead of apply ; , (ii) rank instead of order . set.seed(1) n_i = 10 n_ii = 600 n_top = 5 df <- data.frame(matrix(runif(n_ii*n_i), ncol = n_ii)) out <- matrix("",n_top,n_i) (i in 1:n_i){ colranks <- rank(df[i,]) out[,i] <- names(sort(colranks)[n_ii:(n_ii-(n_top-1))]) } # [,1] [,2] [,3] [,4]
