i'm writing c++ application mymasterapp (windows & mac) listening bunch of information coming different computers , applications.

i'm new in c++ , i'm struggling this. have matrix discrete values adapt gaussian distribution. need algorithm in c++ define parameters of gaussian fit. suggestions or help?? 1 of vectors in data set {14, 3, 2, 83, 263, 236, 101, 27, 7, 13, 12, 8} increment 2 ns between each value. thanks lot as bathsheba said, that's needed characterize gaussian (a.k.a. normal) distribution mean , variance. can estimate these sample mean , sample variance s^2 of data, respectively. however, shouldn't so ! histogram , normal quantile plot of data show nothing gaussian distribution. gaussians should have histogram bell-shaped , symmetric. data, despite small sample size, skewed exponential distribution doesn't particularly fit. in normal quantile plot, if data gaussian points fall along relatively straight line (the red line best fit straight line values) , within dotted-line boundaries. data aren't vaguely close being fit normal distribution.

this question has answer here: why these constructs (using ++) undefined behavior? 12 answers increment values in printf [duplicate] 3 answers #include <stdio.h> print(int* a,int* b,int* c,int* d,int* e) { printf("\n%d %d %d %d %d\n",*a,*b,*c,*d,*e); } main() { static int arr[]={97,98,99,100,101,102,103,104}; int *ptr=arr+1; print(++ptr,ptr--,ptr,ptr++,++ptr); } output: 100 100 100 99 100 i little confused output. because of undefined evaluation order of function or there else missing?

so have function declared as: void writefile (unsigned char *filename, unsigned char *data) if call function this: writefile("f.txt", "test1"); is fine. if second call this: writefile("s.txt", "test2\nline"); the filename fine, data corrupted (the first 5 bytes messed up). if third call this: writefile("f.txt", "test3\r\nline"); the filename corrupted, , data has it's first 5 bytes messed up. what going on? i believe problem has using unsigned chars, when put code complains on compile it. may have unsigned char not being able use escape characters \n , can't sure. intellisense: argument of type "const char *" incompatible parameter of type "unsigned char *" is compile error get. when changed being regular char * parameters, worked fine.

we have 2 apps setup push notifications. (a , b) there different profiles each (of course) , we've generated separate certs each. app receives push notifications fine, app b doesn't. both talking same server - , figure out app it's sending notifications , uses correct cert. i've noticed if install both apps on 1 device, both same token (which our server tracks per app.). when server sends msg in case, sends twice same token - once each cert. app receive msg, app b won't. when sending msgs both apps, apple server responds messages sent correctly no errors. msg never shows 1 app. any suggestions on look? after searching , looking, found question: iphone - multiple apps, different app id, same token it points out must use different .certsigningrequest each app. checked our appstore guy, , had used same 1 both certs. fixed that, , works!

i working program , need remove repeated characters string given me user. referenced other questions, using stringbuilder remove duplicates. however, there way remove duplicates without turning string array, using stringbuilder , set ? i haven't learnt yet, don't understand them well. help? for example, if user types in happyrolling result should hapyroling . it seems example want remove repeated characters (not words ). you can use regex find repeats , remove them: str = str.replaceall("(.)\\1+", "$1"); this regex captures every character matches when followed same character using reference captured group. replacement captured character, example "xx" replaced "x"

for example, like: dt[isflag, newcol:= a] dt[!isflag, newcol:=b] or should this? dt[, newcol:= b] dt[isflag, newcol:=a] or this? dt[, newcol:= if (isflag) else b] # works if isflag scalar or dt[, newcol:= ifelse(isflag, a, b)] # works if isflag vector what best way?

i selecting core data entries , sorting them. straight forward enough because of calculations in sort distance wanted put in alternate thread. did usual way making new nsmanagedobjectcontroller other thread adding code within #ifdef threads sections below. now can fetch, sorting , organizing, without slowing user interface , table updated when ready. but, since doing fetch in local managed object context, fetched objects not valid on main thread - in fact disappear out of table view cells. so, questions are: 1) ok use main managed object context, since reading, , not create local context @ all? 2) should go through , re-fetch objects main managed object context on main thread using objectid values search managed object context objects after sorting , organizing? 3) should fetch on main managed object context performblockandwait keep sort , organize returned objects on searchq thread? 4) else have not thought of? - (void) fetchshoplocations { #ifdef threads dispatch_q...

how attach events after manipulating dom using ajax response. have ajax request html response fragment of html. fragment html have many buttons. want refresh dom declared , attached events applied fragment too. dont want keep on adding each events each button using jquery on(). how else it? you can use delegated event handling set ahead of time , can made apply newly added dom elements. delegated event handling done .on() , takes form of: $("static parent selector").on('click', 'selector dynamic element', fn); there no clean way run event installing code again , have apply newly added dom elements. have put code in function , code such never adds event handler more once , call function again after adding items dom. or, make function take argument parent object , add event handlers in newly added dom hierarchy. here's relevant answer delegated event handling: does jquery.on() work elements added after event handler created?
