i've been searching web past hours trying find way implement routine/function in mathematica plotting. i've written code needs 2 dimensional field, say: dx/dt = x-x^2 dy/dt = y-y^2. what here on solve fix points , numerically integrate few trajectories , plot them together... now question can somehow compose code function in matlab? i've been researching concepts of module, , block seems impossible me return plot. so clarification want able write function takes argument field, , returns plot of field me ( customised trajectories fix points etc.. customplotfield[dxdt,dydt] := ............ since lot of stuff plotting, code pretty large copy pasting chunks of code plots i'm doing regularly feels bit annoying. thanks in advance! as far can tell, on right track looking @ modules: https://reference.wolfram.com/language/tutorial/modulesandlocalvariables.html to return plot evaluate last expression in body of module. or use explit return. ht

bizarre: i have 2 domains: www.domain.com app.domain.com both individual settings.py, urls.py, , wsgi.py files (set this: http://michal.karzynski.pl/blog/2010/10/19/run-multiple-websites-one-django-project/ ) sometimes--maybe 30% of time--everything works fine. when visit www.domain.com, have pages such /login, /contact, /join. it's standard django site. app.domain.com single page app, urls file looks this: from django.conf.urls import include, url .app_views import index urlpatterns = [ url(r'^.*$', index, name='app'), ] so, time user visits app.domain.com or app.domain.com/foo or app.domain.com/anything, want render index function. now, sometimes, i'll visit app.domain.com, , www.domain.com template rendered. not that, i'll have urls such app.domain.com/login or app.domain.com/contact weird! even stranger, if go www.domain.com, app.domain.com index template rendered! if refresh page few times, correct page, seems random ,

assume have 30 variables, looking way find value hold biggest value. need 'name' of it, not value of it. example: i1=10 i2=12 i3=14 i4=90 i5=5 i6=90 how can code function return 'i4' , 'i5'. not return 90. one way first find maximum comparing each variable can find out name of variable. but, not efficient if have lot of variables. has idea? in advance. it's better use cell arrays sort of thing, anyway this: names = who('-regexp', 'i[0-9]+'); values = cellfun(@eval, names); maxvalue = max(values); maxnames = names(values == maxvalue)

i have list filled contacts. load contacts in list async class. in list class have setonitemclicklistener implemented. in setonitemclicklistener place selected contact in array can sent text them. working dream. but there small problem. when selecting contact in list there multiple contacts selected this: -normal contact- -selected contact- -normal contact- -normal contact- -normal contact- -normal contact- -selected contact- i load contacts code: @override protected void onpostexecute(arraylist<list_item_person> contacts) { // todo auto-generated method stub super.onpostexecute(contacts); pd.cancel(); personlistadapter adapter = new personlistadapter(getactivity().getapplicationcontext(), r.layout.list_item_person, contacts); list.setadapter(adapter); } this async class and onclick this: list.setonitemclicklistener(new adapterview.onitemclicklistener() { @override p

i using jquery + wow + animate appearing div animations on page. working except page not loading smoothly. divs should appear smoothly first appear on page load, hide , after appear animation. please check www.pester.rs , see problem, have tried nothing works. it loading order issue - first, browser downloads document , display it. later when loads entire javascript hides content provide nice animation. think it's affected internet connection speed. solution 1 : hide content css load hidden cons: if javascript crashes, content stay hidden solution 2 : place code @ end of body, before other scripts loaded (before other script tag) var wows = document.getelementsbyclassname('wow') (i = 0; < wows.length; i++){ wows[i].style.visibility ='hidden'; } it executed right after page loading before jquery , should fast enough. solution 3 : use inserted css file head of document suggested there http://robertnyman.com/2008/05/13/how-to-hide-and-sh

i'm few weeks learning sql, , finished problem on homework assignment using in , not in. managed correct answer, however, used except clause, aren't allowed use yet. can tell, except , not in similar statements in sql, can't understand difference is. here's general format of query: select * table x in ( select x /* ... subquery*/ except select x /* ... other subquery*/ ) is there way rewrite general query without using except statement? how except , not in differ each other in general? edit: this other post seems have information, seems focus on exists , not in, have different purposes don't they? this might understand difference between except , not in except operator returns distinct rows left hand side table not exist in right hand side table. on other hand, "not in" return rows left hand side table not present in right hand side table not remove duplicate rows result.

this question has answer here: arraylist or list declaration in java 10 answers what purpose of specifying different types on left , right side in java variable declarations? for example, code standard: list<string> l = new arraylist<>(); why don't: arraylist<string> l = new arraylist<>(); or object l = new arraylist<>(); // silly example shows 2 extremes this list<string> l = new arraylist<>(); allows instantiate types of list , arraylist or linkedlist of string . can use methods of list arraylist<string> l = new arraylist<>(); can instantiate arraylist of string . object l = new arraylist<>(); cannot use list methods.

my scenario: a user login triggers wcf-server kicks off 20 async-tasks . each separate task (named job in code) calling external soap-services. 1 000 simultaneous users logging in, means 20 000 async tasks. must call services in batches (due external limitations), fetch paged data - allowed in parallel. every 1 of 20 tasks spawns 10 tasks of own, mean 400 tasks per individual login - 400 000 tasks 1 000 simultaneous logins. my 2 questions: how impact our iis , server performance? understand tasks queued , run in parallell if possible - there limits on recommended number of tasks? am using right approach in creating these tasks? running async (except waitall )? see code below: create tasks each service called foreach (var job in jobs) { task.factory.startnew(() => job.fetch()); } the job-class called above: public async void fetch() { var batchlist = await fetchbatches(); //saves list database mergeandsavebatchlist(batchlist); } private async

i have record of conversations between 2 arbitrary persons , b. c1 <- "person a: blabla...something person b: blabla else person a: ok blabla" c2 <- "person a: again blabla person b: blabla else person a: blabla" the data frame looks this: df <- data.frame(id = rbind(123, 345), conversation = rbind(c1, c2)) df id conversation c1 123 person a: blabla...something person b: blabla else person a: ok blabla c2 345 person a: again blabla person b: blabla else person a: blabla now extract part of person , put in data frame. result should be: id person_a 1 123 blabla...something ok blabla 2 345 again blabla blabla i'm big fan of solving sort of problem in way gives access data (that includes person b's discourse well). love tidyr 's extract sort of column splitting. used use do.call(rbind, strsplit())) approach love how clean e
