i want create generic asyncetask class activities use/share downloading content url. reason, don't want onpostexecute other send content method in activity invoked asynctask class. i know need create constructor sets context of activity invoked asynctask , what, how use context send the activity corresponding context. i've seen no tutorials show how use context in manner. lets have: public class loginactivity { public int activitymember; public void handlebuttonclick(void){ downloadfromurl task = new downloadfromurl(this); task.execute(url); } public void handleloginresult(int x){ activitymember = x; } } now in separate java file have: private class downloadfromurl extends asynctask<list<namevaluepair>, long, jsonobject> { context context; public void downloadfromurl (context context){ this.context = context; } @override protected void onpostexecute(jsonobject json) {

i'am working on own graphics engine using opengl , glut (under linux, c). problem sprite loader.basicaly, have structure holds data rendering part of texture, this: struct sprite { vertex start,end,size; int textureid; } and have function renders screen. textureid represent id of texture. vertices start , end represent uv coordinates(between 0 , 1), specify top left(start) , bottom right(end) of sprite want render. vertex size specifies actual size of sprite in screen space. part of function splits big texture in smaller sprites. math part of , made c app test , does`nt work how want. s.u , s.v start uv coordinate(top left of sprite), x(s.u) , y(s.v) . e.u , e.v end coordinate(bottom right of sprite). nx , ny number of splits on texture( in image bellow there 2 horrizontal splits , 2 vertical splits. id represents sprite want. s.u=(1.0f/nx)*(id%nx-1); s.v=(1.0f/ny)*(ny-id/nx); e.u=s.u+(1.0f/nx); e.v=s.v-(1.0f/nx); for example if give fu

in asp.net can give same name session variable , cache variable session["lookup"] = "a"; cache["lookup"] = "a123"; ? will not clashed @ access point in page ? do mean cache collection ? if so, not same collection session. session application wide user specific collection cache application wide not user specific. not same object. from msdn: one instance of class created per application domain, , remains valid long application domain remains active. i should warn cache collection global object users, , therefore think user specific information should avoided. best practices , use: http://msdn.microsoft.com/en-us/library/aa478965.aspx

i want following: load png image python code get pixel pixel rgb data in 3 arrays, 1 each r, g , b. mean r[i,j] should give me value of r @ i,j th pixel of image. once have arrays can edit data. plot edited data using 3 array r,g , b , save png image how in python? use pil load image: from pil import image img = image.open('yourimage.png') i'm going suggest method messes directly image data, without accessing individual pixels coordinates. you can image data in 1 big byte string: data = img.tostring() you should check img.mode pixel format. assuming it's 'rgba', following code give separate channels: r = data[::4] g = data[1::4] b = data[2::4] = data[3::4] if want access pixels coordinate like: width = img.size[0] pixel = (r[x+y*width],g[x+y*width],b[x+y*width],a[x+y*width]) now put together, there's better way, can use zip : new_data = zip(r,g,b,a) and reuce: new_data = ''.join(reduce(lambda x,y: x+y, z

i implementing solution using opencl , want following thing, example have large array of data want copy in gpu once , have many kernels process batches of , store results in specific output buffers. the actual question here way faster? en-queue each kernel portion of array needs have or pass out whole array before hand let each kernel (in same context) process required batch, since have same address space , each map array concurrently. of course said array read-only not constant changes every time execute kernel(s)... (so cache using global memory buffer). also if second way faster point me direction on how implemented, haven't found concrete yet (although still searching :)). cheers. i use second memory normally. sharing memory easy. pass same buffer each kernel. in real-time ray-tracer. render 1 kernel , post-process (image process) another. using c++ bindings looks this cl_input_mem = cl::buffer(context, cl_mem_write_only, sizeof(cl_uchar4)*npixels, nu

i extending jquery method find given selector using given function way traverse through this's siblings. the reason i'm doing because jquery's next() doesn't keep traversing object's siblings, need. (function ($) { $.fn.extend({ findsibling: function (selector, fn) { var $this = $(this), $sibling = fn($this); if ($sibling.length === 0){ console.log("no " + selector + " found."); } else if($sibling.is(selector)) { console.log(selector + " has been found!"); return $sibling; } else { $sibling.findsibling(selector, fn); } } }); }(jquery)); $next = $this.findsibling('.line', function (object) { return object.next(); }); even when function finds i'm looking for, $next remains undefined. thanks help. $sibling.findsibling(selector, fn); should be return $sibling.findsibling(selector, fn);

i have several projects in different folders, can run several zeus instances, different port each one? i have gotten till https://github.com/burke/zeus/blob/master/docs/ruby/modifying.md . have no clue if can done. added rails tag people using rails know one. yes can - don't need anything, because zeus using unix domain sockets rather tcp (unlike spork example) say you're working on 2 apps. when in root folder of first app , run zeus start , zeus creates socket called zeus.sock in folder. when run various zeus commands in folder, finds socket , uses talk zeus server. meanwhile second app have own zeus.sock file, in folder. commands run in folder find socket rather first.

what have here loop supposed read output on piece of equipment every 500 milliseconds. part works fine. however, when try introduce cin.get pick key "n" being pressed stop loop, many outputs number of key presses point. if press keys (apart 'n') several times followed enter, few more outputs. need loop keep looping without interaction until want stop. here's code: for(;;) { count1++; sleep(500); analoginput = readanalogchannel(1) / 51.0; cout << count1*0.5 << " " << analoginput << endl; outputfile << count1*0.5 << ", " << analoginput << endl; if (cin.get() == 'n') //problem starts introduced break; }; my output follows (there 2 key presses stage in program) unless press few more keys followed enter: 0.5 0 // expected 1 2 // expected should more values until stopped i have no particular preference in type of loop use, long works. t
