i pretty new programming world, kindly me in solving solution. kindly consider suppose have x , y values. need add arraylist , z third element z's initial value 0 , next iteration onward z's value becomes sum of ((x[1] - x[0])+ (y[1]-y[0]))? how add values z , how sum of z? try this, you can add x values , y values in arraylist of integer or type , this, int xsum, ysum, totalsum; arraylist<int> zsumlist; zsumlist = new arraylist<int>; zsumlist.add(0,0); for(int = 1; < numberoftimes;i++) { xsum = x[i] - x[i-1]; ysum = y[i] - y[i-1]; totalsum = xsum + ysum; zsumlist.add(i,totalsum); } hope helps.

i wanted generate frequencies of 10hz 1000hz step of 10hz, let's within 5s (all frequencies equally distributed within time frame). how achieve individual frequency generator function below? function [ ] = producefeq( frequency, duration, amplitude, freqsampling ) if ~exist('freqsampling', 'var'), freqsampling = 44100; end if ~exist('amplitude', 'var'), amplitude = 1; end if nargin <2, error('not enough input arguments'); end % frequency argument case above 10:10:1000 t = 0:(1/freqsampling):duration; y = amplitude*sin(2*pi*frequency*t); sound(y, freqsampling); end thanks in advance! you can call producefeq multiple times , use pause wait between multiple executions. totalduration = 500; frequencies = 10:10:1000; duration = totalduration/length(frequencies); = 1:length(frequencies) producefeq( frequencies(i), duration) pause(duration) end

why following behave unexpectedly in python? >>> = 256 >>> b = 256 >>> b true # expected result >>> = 257 >>> b = 257 >>> b false # happened here? why false? >>> 257 257 true # yet literal numbers compare i using python 2.5.2. trying different versions of python, appears python 2.3.3 shows above behaviour between 99 , 100. based on above, can hypothesize python internally implemented such "small" integers stored in different way larger integers , is operator can tell difference. why leaky abstraction? better way of comparing 2 arbitrary objects see whether same when don't know in advance whether numbers or not? take @ this: >>> = 256 >>> b = 256 >>> id(a) 9987148 >>> id(b) 9987148 >>> = 257 >>> b = 257 >>> id(a) 11662816 >>> id(b) 11662828 edit: here's found in python 2 documentation

my ruby on rails application it’s construction company , in part of have 2 models, 1 called item (rubro) , other called budget . each item created has own price. in budget form have option add different items quantity using nested form. in first column have collection_select works items id select item add, in second column complete quantity, , in third column idea display subtotal value (item price * quantity). my question how can item_id selected in collection_select use item price , show (item price * quantity) in subtotal text_field? it possible that? know using ajax , jquery, new these. or give me other idea of how it? this part of form want said: _form.html.erb <%= f.fields_for :budget_details, :wrapper => false |form| %> <tr class="fields "> <td class="col-md-4"> <div class="col-md-9"><%=form.collection_select(:rubro_id, rubro.all, :id, :name, {prompt:

i use py2.7 have read pickle dynamically parameterized sub-class .it places similar question problem more complex. here more detail code , why use pickle ? or have idea replace apscheduler i have simplify code.please me. example : class base(object): base = none # has more method , more params in class def run(self): print self.base class a(base): params = none def run(self): print self.base + self.params class b(base): params = none def run(self): print self.base * self.params def _create(base_class, p): class c(base_class): params = p return c() def factory(base_class): class_list = [] in xrange(0, 500): class_list.append(_create(base_class, i)) return class_list try: import cpickle pickle except importerror: import pickle a_class_list = factory(base_class=a) b_class_lsit = factory(base_class=b) in a_class_list: o = pickle.dumps(a, pickle.highest_protocol)

recently our app needs replacement in image fetching logic, such client should request image size (image built server dynamically). image url has following format: http://image.server.url/path?width={{width}}&height={{height}} most of custom views built in following pattern: - (instancetype)initwithframe:(cgrect)frame { if (self = [super initwithframe:frame]) { // initializations } return self; } - (void)setimageurl:(nsurl *)url { // image fetching } and instantiated as: someview *view = [[someview alloc] init]; view.imageurl = [nsurl urlwithstring:@"..."]; [self addsubview:view]; this not problem (as images' size static), when requesting image having dynamic size unavailable because, image fetching run before -layoutsubviews called, target image container's size zero. after all, need figure out timing when layout finished (using observer image containers), or have static size image containers. what best solution this?

this question: assume two-dimensional array of ints called 'myints'. write code snippet print each of elements of row m on separate line. may assume m not out of bounds. this work have done not sure going in right direction... for (int = 0; < myints.length; i++) { (int j = 0; j < myints[i].length; j++) { system.out.print (myints[i][j]); if(j < myints[i].length - 1) { system.out.print(" "); } } system.out.println(); } because requirement print values of given row m , think need single for loop, iterate on single row: public void printrow(int[][] array, int m) { (int i=0; < array[m].length; ++i) { system.out.println(array[m][i]); } } i didn't bother checking bounds of input m , because said don't need to. in case, printrow() throw arrayindexoutofboundsexception should index m out of bounds.

this more of practice question... we're converting jsf managed beans cdi beans in jsf 2.2 . while doing this, seems in lot of beans, need few sessionscoped beans. we intended @inject those, option inject them protected variable in parent "facesbean" class. would practice? does @inject work in @managedbean classes not yet converted cdi? so 1 one: 1) practice? if have class hierarchy, suggest @inject private field in parent , create getter method minimum needed visibility (probably protected). stick general practice rules around encapsulation in java. 2) @managedbean , @inject ? as long use bean discovery mode all (use empty beans.xml ), classes automatically picked managed beans - including annotated @managedbean . , bean, injection works. yes, injection work long class can become bean automatically (e.g. not @vetoed or unproxyable etc.)

i'm starting bdd , after readings found out goes ddd. now have domain, institution have places , added institution assignee user assigned manager of organization. i still can't wrap head around how should be, feature sounds like: as assignee of institution must able add places organization the code i'm thinking (sorry code-first approach) this: if ($institution->isassignee($user)) { $institution->addplace(/* properties*/); } now how should write feature , scenarios? should leave as assignee part , leave it? or should there multiple scenarios? how scenario like? edit: so left user permission check , started first feature followed specifications of implementation. code found here . isn't feature simple? of course core of domain does, did not mentioned case in feature place same location not added, have done in institutionspec ? moving forward: if edit place of institution, better approach: $place = $institution->getplace($placeid

i make structure using comsol want make structure subjected temperature variation ( t(begain)=25c temperature ramp (100 c/min) till t=250c , lasts 30 min temperature ramp (-100 c/min) till t=25c ).how make these temperature sweep? you can define function (e.g foo) follows desired temperature time profile. in place specify temperature (whether boundary condition or domain condition) insert foo(t), t being comsol's exclusive variable name time. you can other variables too, space instance. easiest way define foo through 1d interpolation option. unfortunately, not have comsol license check think can enter time , temperature values in 1d interpolation table, choose name , interpolant style , use in later part of program.
