in tests, capture output of each test , save them html files in directory. how can provide link these outputs each test in testng reports? e.g. if there failure recorded in testng results, provide link saved html files. thanks it depends on , how want report results. sounds want create custom testng report contain information on status link file generated. there 2 main ways accomplish in testng: create test listener - implements org.testng.itestlistener , reports status of every tests after tests executed. create test reporter - implements org.testng.ireporter , provides consolidated result of test statuses, when tests executed. you can refer testng web site examples on listeners.

i have asked question on hebbian learning before, , guess got answer accepted, but, problem realize i've mistaken hebbian learning completely, , i'm bit confused. so, please explain how can useful, , for? because way wikipedia , other pages describe - doesn't make sense! why want keep increasing weight between input , output neuron if fire together? kind of problems can used solve, because when simulate in head, can't basic and, or, , other operations (say initialize weights @ zero, output neurons never fire, , weights never increased!) your question seems rather theory-related, , i'm not sure if belongs so, since directly connected neural networks, i'll try answer. we increase weight between input , output neurons if fire because firing means somehow related. let's use example of logic functions. in and function, have 2 input neurons. if input data (0, 0) , means neither input neuron fire, , neither output. don't need strong connect...

i can't figure out way match uitouch objects in uikit corresponding touch objects in javascript. for uitouch, 1 typically uses value returned hash message identify uitouch instance across touch phases. in html / javascript, touch.identifier used , guaranteed unique number across multiple touches. however, numbers returned [auitouch hash] , atouch.identifier not related. ideas on how can match touch objects received in javascript notifications uitouch objects received in obj-c? thanks. the solution came store uitouch objects in dictionary using key derived location. so, touch occurred @ x 120 y 200 stored using key "120:200". happens when overriding sendevent method of main window class. i add information these touches (in case, radius of touch area) , push them dictionary in javascript runtime using similar scheme. in general positions reported webkit match reported window class, javascript runtime able use current location of touch hash lookup to...

i have canvas draw chart. when clicking button want generate view jpeg image. in fact, works, resulting image not correspond draw on chart. please see screenshot: i don't have idea happens, in resulting saved image, lines should appear @ top of chart, appears moved lot down. do guys have idea why behaviour may occur? here relevant snippets of code: @override protected void ondraw(canvas canvas) { super.ondraw(canvas); drawlines(canvas); drawpoints(canvas); // other drawing operations converttojpegfile(canvas) } //the method conversion jpeg public void converttojpegfile(canvas canvas) { string imagename = "/chart.jpg"; try { this.setdrawingcacheenabled(true); fileoutputstream fos = new fileoutputstream(new file( environment.get...
