i getting large amount of data web service. if amount of records return more 1500 or 2000 memory overflows , app crashes. don't need save data locally, have present data user. how can manage not crash , display whole of data? the best way go ahead change web service accept page param , return paginated results. make seamless in tableview, can add infinite scrolling - i.e. if user reaches row <last-10> , send request next set of records , load them in table view. but this, assuming face memory issues if persist 2k records (your data array) in memory. memory management needed there well.

i've came across git behavior cannot understand. repo used tens of people. case this: $ git checkout master $ git merge --no-commit feature automatic merge went well; stopped before committing requested $ git status on branch master branch up-to-date 'origin/master'. conflicts fixed still merging. (use "git commit" conclude merge) changes committed: modified: web/webapp/grails-app/views/layouts/empty.gsp $ git commit -m 'commit message' [master e6cc2eb] commit message $ git status on branch master branch ahead of 'origin/master' 21 commits. (use "git push" publish local commits) what confuses me part: your branch ahead of 'origin/master' 21 commits. how come it's not 1? make clear, there single change in empty.gsp file. there 20 more commits, why not show after git status ? hints might missing?

okay let me explain little better. have mvc project html page , images , have set smtp server send email. when debug webpage localhost url. (localhost:51180) email try send looks this: (simplified version): <html> <body> <img alt="img" src="https://www.google.com/images/srpr/logo11w.png" />*working <img alt='img' src='localhost:51180/images/img.png'/> *not working </body> </html> my problem second pic doesn't work. (if copy past url in web browser while project running can see right path). because website running local on computer , email cant access it? or else? in advance! a couple things try.. #1 try changing url http://localhost:51180/images/img.png . should have protocol in there ( http ) i'm not sure can this... #2 use base 64 encoding of image embed it. e.g.: <img src="base64;==asdlfnlansl;34n5ljl5jslj5;hl;sh5j..." />

for example let's have windows form textboxes numbers , button, , when click on button want take value of of texts , math them. would this: private void btnsomeresult_click(object sender, eventargs e) { dosomemath(); } be better practice say: private void btnsomeresult_click(object sender, eventargs e) { //complex math goes here. } or depend on complexity of operation? example may not needed in simple multiplication, division etc. private void btnsomeresult_click(object sender, eventargs e) { dosomemath(); } this approach better suited because of following reasons if ui changes, replacing button another button need same function, can reuse functionality written. in essence, ui independent of functionality of button control. you can test method (dosomemath) if start unit testing. a still better way data ui elements , pass on method parameters in more specific class/type ensure data independent of ui controls // function reads dat...

i'm trying build simple progress bar script display bar current action in progress. with of echo -ne "[||...] processing ${file_name}\r" can display progress bar as: [||||||||............] processing file1 however i'm expecting output this: processing file1 [||||||||............] note: both seperate lines , want update them both script progress. is there way achieve this? you can use tput cuu 2 move cursor 2 lines, , tput el clear current line: while sleep 1 tput el; date tput el; echo "$random" tput cuu 2 done this produce 2 changing lines of e.g. thu jul 23 17:50:46 pdt 2015 23676

since yesterday i've been struggling thousands of data in excel. reduce amount of data have, decided take important ones , remove others. goes identical strings smaller values in case. let's take 3x2 data: b --------------- 1 | abc123 | 10 | --------------- 2 | abc123 | 50 | --------------- 3 | abc123 | 300 | --------------- so can see there 3 identical strings, yet have different values. want compare values between these identical strings, , keep string biggest value , delete analogues. this simple example. there tons of identical strings in file have different values. , (somehow) biggest 1 optimal one, don't need rest of them. and question is, supposed accomplish this? functions, formulas, anything? i'd appreciate help. lot! you sorting range values(biggest smallest), go data tab, , use 'remove duplicates'. make sure have column selected strings when remove duplicates, , nothing else. otherwise, may lose more data mea...
