问题 I'm want to calculate ray directions from camera to pixel positions (in world coords) with given height as described in this paper. Camera image size is 640,480. I calibrated the intrinsic camera parameters and undistort each image. I measured the physical distance between camera and background plane (29 cm) as sketched here: 1 cm translates to 25 pixel (assuming quadratic pixels). My first approach was to calculate based on pixel- and camera position as follows: float3 pixPos = (float3)(u, v

问题 I am looking for a simple native .NET error logging solution. I am not interested in using log4net, Elmah or any other logging library. Below is what I am planning on using. My question is performance on my site is paramount and does this flow introduce any performance concerns? Global.asax protected void Application_Start(object sender, EventArgs e) { GlobalFilters.Filters.Add(new HandleExceptionsAttribute()); } Handle Exceptions Attribute: public sealed class HandleExceptionsAttribute :

问题 I have a strange bug in python code which only happens sometimes in CI. We can't reproduce it. Where is the test code: response=self.admin_client.post(url, post) self.assertEqual(200, response.status_code, response) Sometimes we get a 302 which happens since the form gets saved. My idea to debug this: with some_magic_trace.trace() as trace: response=self.admin_client.post(url, post) self.assertEqual(200, response.status_code, trace) The trace should contain the python lines (filename, line

问题 I have a PDF generated by 3rd party system. Using PDF editor or els software I have modified it. Is it possible to detect if PDF file was modified, without original file? I will add some more details. There is no encryption and no signature features. Document is created by IT system. User receives document and modifies it. Is it possible to track that change somehow? I thought that all these applications leaves some data in PDF header or somewhere encoded inside file and it is possible to

问题 I am trying to understand how does Tracing works I have created a simple new web project. This is my code that I can using // Create a trace listener for the event log. EventLogTraceListener myTraceListener = new EventLogTraceListener("myEventLogSource"); // Add the event log trace listener to the collection. Trace.Listeners.Add(myTraceListener); // Write output to the event log. Trace.WriteLine("Test output"); I am taking help from this msdn link The settings in my web.config is as follows

问题 I am trying to get tracing set up for Powershell(ISE) and I came across this link, but I am running debugView, and nothing seems to be happening. Anyone know what I am doing wrong? Basically my goal is to get tracing for System.Net.Webrequest working in powershell. If there is another way to do it, I'd also be open to that. 回答1: The answer - which is mine funnily enough - in that link refers to the regular console (powershell.exe) version of powershell. I have to ask some dumb questions: You

问题 I am developing a program under Linux. For debugging purposes I want to trace all calls from my program to a certain (preferably shared) library. (I do not want to trace calls happening inside the library.) For syscalls there is strace. Is there any instrument to trace calls to a shared library? 回答1: The tool you are looking for is called ltrace . It allows to trace any call from the program to all (or a set of given) libraries. For example, the following call will list any call to an

问题 I've been trying to setup trace logging for a while and I simply can't get it to work properly. It doesn't help they are so many wrong/outdated articles on this topic. But please can someone give me a good and practical setup for trace logging & viewing for Azure (1.6) All I want to do is the ability to capture and view trace messages from my app. I started out with standard DiagnosticMonitorTraceListener but that ends up in table storage. I can't for the life of me figure out how I'm

问题 On my application, after enabling ASP.NET Tracing in an ASP.NET MVC application, the time calculation statistics were off by a factor of 5000. I have a page that is taking between 7 and 9 seconds to load. This is corroborated by both Firebug and the "time-taken" field in the IIS log files. (This is just the page returning to the client, not any layout, DOM, or script execution.) However, when I turn application-wide tracing on (via web.config) and view the trace output, the time taken from

问题 Say you have C# trace messages all over an application. Something like: Trace.TraceInformation("Service Started"); How do you automatically log this to an nLog target without having to add code like the following to all the classes that have trace messages? using NLog; private static Logger logger = LogManager.GetCurrentClassLogger(); Is there a way to do this without including traces produced by the .NET Framework itself, which this article demonstrates how to do? 回答1: This works for cases
