Arrya Code

thanks feedback guys, have rewrite question make more clear. say, have table: table what trying table list of numbers have matching fp_ndt dates condition, example, want list of numbers, have fp_ndt not null 2014 , 2015 , missing values 2011, 2012 , 2013 (irrelevant of months). condition should number 4. possible table ? ps: if write simple sql select statement , put condition where year(fp_ndt) in (2014,2015) it give me numbers 2 , 3... why not first summarize data? proc sql; create table xx select number , max(year(fp_ndt)=2011) yr2011 , max(year(fp_ndt)=2012) yr2012 , max(year(fp_ndt)=2013) yr2013 , max(year(fp_ndt)=2014) yr2014 , max(year(fp_ndt)=2015) yr2015 table1 group number ; now easy make tests. select * xx yr2014+yr2015=2 , yr2011+yr2012+yr2013=0 ; you use first query sub-query instead of creating physical table.

not sure if there solution problem. want know if there way detect when browser actually updates ui. lets want add class element before run long-running, synchronous block of code, after synchronous function runs, class removed. el.classlist.add('waiting'); longrunningsynchronoustask(); el.classlist.remove('waiting'); if run code, long running task started, , block ui before class added. tried using mutationobserver 's, , checking element getcomputedstyle , doesn't work because don't reflect when realtime updates ui. using worker might best solution (drop long running code in worker , post message when it's complete remove class). isn't option me, due needing support older browsers. the solution works outside of implementing worker using settimeout . i'd love know if has run problem , if there way detect repaint/reflow of ui in browser. see example better illustration of problem. const el = document.queryselector('.targe

do know how have 2 different copies of same file in 2 different branches in git? let assume have file called config . i'm trying achieve have copy of file in dev branch different in master branch. the important thing file can't ignored in gitignored. you can checkout 2 branches. modify file , commit them each branch. if want merge branches , have 2 separate files (different content) in each branch, commit changed branches , set desired file tin .gitattributed grab ours file - result in file never overwritten read , set here: https://git-scm.com/book/en/v2/customizing-git-git-attributes#merge-strategies you can use git attributes tell git use different merge strategies specific files in project . one useful option tell git not try merge specific files when have conflicts , rather use side of merge on else’s. this helpful if branch in project has diverged or specialized, want able merge changes in it, and want ignore files . config_fi

this question has answer here: learning regular expressions [closed] 1 answer i new regular expressions , clueless @ moment. i trying create regular expression in java allow alphabetical characters. integers , special characters not allowed. minimum length possible 2 , maximum length 10. (^[a-za-z]{2,10}$) or (\a[a-za-z]{2,10}\z) you downcase first , make smaller regex if doesn't matter these should work.

i learning angular 1.5 , js @ same time. assigning defaults notify.js. have code has no errors, have feeling else if done in better way. also, try , put returns in, errors. please show me best way if else , returns go (bottom or inline?). still have hard time ending functions , semicolons. know these odd but, no errors. thank you. function notificationservice ($scope, $) { var vm = this; /** * @see notifyjs.com */ vm.publish = function (type) { if (type === 'info') { $.notify.defaults({ scope: $scope, classname: 'info', autohide: true, position: 'bottom' }); } else if (type === 'success') { $.notify.defaults({ scope: $scope, classname: 'success', autohide: true, position: 'bottom' }); } vm.publ

i'm trying create 3d matrix in javascript, , want update values using coordinates: var xaxis = []; var yaxis = []; var zaxis = []; var dimensions = 4; //initalize matrix (var i=0;i<dimensions;i++){ xaxis.push(0); } (var j=0;j<dimensions;j++){ yaxis.push(xaxis); } (var k=0;k<dimensions;k++){ matrix.push(yaxis); } //check value of 1 point in matrix matrix[1][2][3]; //returns 0 expected //update value of matrix using same coordinates matrix[1][2][3] = 2; when run last step, not update expected 1 [2][3] coordinates, updates every third value of every array 2 see in image: how can manage update value want?? mean, number 2 should in 1 coordinate point, in case 1 [2][3]. note: think it's got might assigning original arrays matrix instead of new copies of themselves, when update 1 coordinate, i'm updating original array, , other arrays pointing @ original, that's why it's been reflected there well? you push arrays reference. c

i want show video , audio waveform @ same time in javascript video player. position should synchronized, ie if play video, position in waveform view should adapt. tried following using wavesurfer.js cannot figure out how synchronize it: <video id="video" class="video-js vjs-default-skin" controls> // replace these own video files. <source src="video.m4v" type="video/mp4" /> html5 video required example. </video> <audio id="myaudio" class="video-js vjs-default-skin"></audio> <script> var player = videojs("myaudio", { controls: true, autoplay: true, loop: false, width: 600, height: 300, plugins: { wavesurfer: { src: "media/heres_johnny.wav", msdisplaymax: 10, wavecolor: "grey", progresscolor: "black", cursorcolor: "black",

so i'm supposed write block of code opens file called "words" , writes last word in file file called "lastword". have far: file *f; file *fp; char string1[100]; f = fopen("words","w"); fp=fopen("lastword", "w"); fscanf(f, fclose(fp) fclose(f); the problem here don't know how read in last word of text file. how know word last word? this similar tail tool does, seek offset end of file , read block there, search backwards, once meet whitespace or new line, can print word there, last word. basic code looks this: char string[1024]; char *last; f = fopen("words","r"); fseek(f, seek_end, 1024); size_t nread = fread(string, 1, sizeof string, f); (int = 0; < nread; i++) { if (isspace(string[nread - 1 - i])) { last = string[nread - i]; } } fprintf(fp, "%s", last); if word boundary not find first block, continue read second last block , search in it,

ok, kinda got assignment, , not sure means. the guy told me "converting" code older version of vs newer one, not sure versions said, lets take these said correct. language c++, , supposed here? mean, differences in vs's? maybe misunderstood said, anyway i'm lost, anyone? the following typical sequence of tasks: load old vs2005 project file in vs2008 vs2008 prompt convert project file vs2008 format, that build project fix flagged error newer compiler test resulting compiled code of course c++ language did not change between years. other things vs might have.

i jst started using numpy week, , confused it. seems different normal python functions. with array, shape of 1000x6, there way go row row in array , check example equilateral triangle.i have 6 columns there triples in each row, 2 integers each point. import numpy np pnts = np.random.randint(0,50,(1000, 6)) i thought may better create 3 arrays this: import numpy np = np.random.random((10,2)) b = np.random.random((10,2)) c = np.random.random((10,2)) to create ordered pairs , use algorithm find triangle. is there better way create array represent 1000 triples of ordered pairs , how can find triangles in array, equilateral triangle example. i have made changes now. made 2 arrays x coordinates , y coordinates. x = np.random.randint(0,10,(3,1000)) y = np.random.randint(0,10,(3,1000)) ############# adding question ############# i have algorithms take each matching x , y coordinates find there side length , angles each triangle. post code. , have functions use angles ,

i know question asked here: is there way increase height of strip.text bar in facet? i want decrease height of strip.text bar without changing text size. in current case there space left between text , strip bar walls. here tried far, library(gcookbook) # data set library(ggplot2) ggplot(cabbage_exp, aes(x=cultivar, y=weight)) + geom_bar(stat="identity") + facet_grid(.~ date) + theme(strip.text = element_text(face="bold", size=9,lineheight=5.0), strip.background = element_rect(fill="lightblue", colour="black", size=1)) in case seems lineheight not affect if changed 5 . why? how can make strip bar size little smaller keeping text size same? edit after @sandy muspratt answer we able reduce strip size if there 1 row of facets . g = ggplotgrob(p) g$heights[c(3)] = unit(.4, "cm") # set height grid.newpage() grid.draw(g) however, in real data have many rows of plot below , when changed elements of g$heights nothi
