i given following question in technical interview: how remove duplicates unsorted array? one option thinking of: create hash map frequency of each number in array go through array , o(1) lookup in hash map. if frequency > 0, remove number array. is there more efficient way? another option sort array o(nlog n) using quick sort or merge sort then iterate through array , remove duplicates why option 1 better option 2? i cannot use functions work array_unique. instead of removing object array if hash map says there duplicate, why don't build new array each item in hash map, , add array if there isn't duplicate? idea save step of having 2 arrays equal overhead @ start. php sucks @ garbage collection if start massive array, though unset value, might still hanging around in memory.

the common way send request server is $.get('link/to/send', { param1: "value1", param2: "value2" }, function(result) { // ... etc }); now if want send dynamic parameter names, can jquery support that? (i.e. need write generic code can specify parameter names @ runtime) this not jquery dependent, it's vanilla javascript. you should this: var objtosend = {}; objtosend["param1"] = "value1"; objtosend["param2"] = "value2"; $.get('link/to/send', objtosend, function(result) { // ... etc });

here twurl command: twurl "cursor=-1&screen_name=forexcom&count=5000" /1.1/followers/ids.json this twitter account has 70k followers. when above command own 1600+ followers in list. the command formulated according twitter api guidelines here: https://dev.twitter.com/rest/reference/get/followers/ids i have tried , without cursor, using either screen_name or user_id or both. have passed count=1000 . nothing works. 1600+ of own followers. it's though not passing arguments @ all. can see errors in command? the format used post requests, -d switch added, of course. get requests should have parameters appended in query string: twurl "/1.1/followers/ids.json?cursor=-1&screen_name=forexcom&count=5000" the above query works.

i use cern root draw 2d graph of pairs of x-y datapoints possibly y-errorbars . know how draw histograms. is possible cern root? if how? also realize there may better libraries doing this. have been using gnuplot, unfortunately can't seem integrate c++ code, since can't find c/c++ gnuplot interface covers features , allows me send data in bidirectional manner - ie: both , gnuplot. if have better alternative suggestion welcome. there gnuplot iostream send data c++ gnuplot. within root, can use (as suggested others) tgraph , tgrapherrors , tgraphasymerrors . edit: the gnuplot iostream example homepage looks this. means once have data points either 1 vector of tuples or several vectors of floats, can send them gnuplot. #include <vector> #include <cmath> #include <boost/tuple/tuple.hpp> #include "gnuplot-iostream.h" int main() { gnuplot gp; // create script can manually fed gnuplot later: // gnuplot gp(">

i following code: sg = fiber.new s = 0 loop square = s * s s += 1 s = fiber.yield(square) || s end end puts sg.resume puts sg.resume puts sg.resume puts sg.resume 40 puts sg.resume puts sg.resume 0 puts sg.resume puts sg.resume when run, outputs: 0 1 4 1600 1681 0 1 4 how line 6 s = fiber.yield(square) || s work? think understand component parts not line whole doing. (is there alternative way of writing might better me understand?). (edit: code modified example page 295 'beginning ruby, novice professional 2nd ed' peter cooper.) according docs yield any arguments passed next resume value fiber.yield expression evaluates to. the line s = fiber.yield(square) || s assigns argument passed resume s . if value nil (or argument missing), s re-assiged s (i.e. doesn't change). example: sg.resume #=> s = nil || s #=> s = s sg.resume 40 #=> s = 40 || s

i configured authentication using remote_user in django project, replacing default modelbackend. however, when call admin page still redirects login page. tested with: curl -i -h 'remote_user: ruser1' http://localhost:8765/admin/myapp/mytable/ location: http://localhost:8765/admin/login/?next=/admin/myapp/mytable/ [edit: wrong - tested remote_user=ruser1 ./manage.py runserver] the remote user has been added auth_user table. my related config snippets are: middleware_classes = ( ...

i have ipython jupyter notebook i've developed , run django 1.8 with: manage.py shell_plus --notebook within notebook have written data analytics , reporting modules produce csv , html output via petl , pandas. i'd automate notebook in such way can cron notebook cells execute , serve static html output, don't see way run cells within notebook without human driving process, i.e. cron. nbconvert has --execute flag run notebook before converting format. so instance, run notebook , convert static html: ipython nbconvert --execute --to html mynotebook.ipynb if want run , save results ipynb file, can use --to notebook .

i have stored procedure runs pull data sales in given month. not return 31 days on months have 31 days. need understanding breakdown of following string (dateadd(dd,-(datepart(dd,getdate())),convert(char(8),getdate(),112)))+'23:59:59') i understand convert(char(8),getdate(),112) taking system date , converting yyyymmdd , datepart(dd,getdate()) takes system date , takes day part, cannot decipher entire string. there issue expression have given. bracket after 23:59:59 not have opening brace. however expression intends is: (datepart(dd,getdate())) getting the current date's day part convert(char(8),getdate(),112)) getting current date in yyymmdd (dateadd(dd,-(datepart(dd,getdate())),convert(char(8),getdate(),112))) subtracting day part today's date (see negative sign). thus trying first day of current month. in case result of above expression crosses last day of previous month, adds 23 hours 59 minutes. the logic intended last day of previ

i have searched online extensively, cannot find discussion. is there way modulate border radius of object using css animation? looking kind of (either 1 of circles, not both): does have general idea if possible? i'm not looking exact replication, simple implementation of border-radius effect. ideas. this close can get: http://codepen.io/anon/pen/bnbnpg?editors=010 @-webkit-keyframes mymove { 25% {border-radius: 120px 100px 120px 110px;} 50% {border-radius: 100px 120px 110px 120px;} 75% {border-radius: 120px 110px 120px 100px;} 100% {border-radius: 110px 120px 100px 120px;} } i try doing code pen add instead. added border spins 1000 degrees lol div { width: 100px; height: 100px; border-radius: 100%; border-color: red; border-style: solid; position :relative; -webkit-animation: mymove 5s infinite; animation: mymove 5s infinite; } @-webkit-keyframes mymove { 25% { -webkit-transform: rotate(10000deg); } 25% {bo

i'm plotting q-q plots using qqplot function. it's convenient use, except want color data points based on ids. example: library(qualitytools) n=(rnorm(n=500, m=1, sd=1) ) id=c(rep(1,250),rep(2,250)) mydata=data.frame(x=n,y=id) qqplot(mydata$x, "normal",confbounds = false) so plot looks like: i need color dots based on "id" values, example blue ones id=1, , red ones id=2. appreciate help. not used qqplot before, want use it, there way achieve want. looks function invisibly passes data used in plot. means can this: # use qqplot - generates graph, ignore plotdata <- qqplot(mydata$x, "normal",confbounds = false, col = sample(colors(), nrow(mydata))) # given have data generated, can create own plot instead ... with(plotdata, { plot(x, y, col = ifelse(id == 1, "red", "blue")) abline(int, slope) }) hope helps.

i have many projects in ios. of them use same classes (app1, app2 , app3 use same classes class1.m , class2.m ). there way collect these apps in 1 app (multi task) or use these classes 1 time apps? actually can compile classes static library , add future projects dependency. this tutorial it.
