问题 This code acts as expected printing "Average Number of Runs: 0.99864197" import java.util.Random; public class A { public static void main(String[] args) { int min = -30; int max = 1; test(min, max); } static void test(int min, int max){ int count = 0; Random rand = new Random(0); for(int j = 0; j < 2097152; j++){ int number = min + rand.nextInt(max-min+1); for(int i = 0; i < number; ++i) { System.out.print(""); count++; } } System.out.println("Average Number of Runs: " + count/65536F); } }

问题 I have been struggling for almost three days now on this task, and I guess I am missing on some basic cURL skills. I start with: In the F12 of IE I see 2 POSTs on the first page: (I notice the first one is getting a 302 which is supposed to be a redirect, and with cURL I only get 200) Filling up the captcha: on the second page (after captcha): traffic: This is my code (and I cannot move on with it because it doesn't work for the early stages): I Built a special form that submits to my own

问题 I've got a static method, MyClass::myMethod() on another DLL, MyDll.dll . In my code, I call this method, and it compiles and runs fine. But when I try MyClass::myMethod() in the immediate window (or the watch window), I always get: MyClass::myMethod() CXX0052: Error: member function not present Why is that? Update : I've found out that when I use the context operator it works: {,,MyDLL}MyClass::myMethod() I'm not really sure why it's needed, though, so I'm going to wait a bit to see if

问题 Visual Studio loads the correct PDB file, but can't find source information for anything in the solution. Things I've tried: Clean, reboot, regenerate project (CMake), rebuild Check the Modules window to ensure the PDB is loaded (it is) Mess with "Debug Source Files" setting under solution properties Check the PDB file with symchk (it says the PDB matches the EXE, and that it has full symbol information, i.e. it's not stripped) Download system lib symbols from Microsoft because why not Is

问题 Is there a way to make Rstudio tell you which line of which sourcefile generated a warning message? Right now it just prints the message and I am lost as to what is causing the issue. In Rstudio, this menu option is checked: Debug > Error > Error Inspector But it doesnt' help, probably because these are warnings and not errors? Ideas? 回答1: First turn on displaying warnings using the command options(warn=1) Then, you could run it by clicking on the "Source" or "Source with Echo" button (see

问题 Computer setup: Mac OS X Yosemite My gdb functions well before. But today, When I try to use gdb to debug: (gdb) run Starting program: /Users/JackZhao/Desktop/work/reviewC/pp Unable to find Mach task port for process-id 627: (os/kern) failure (0x5). (please check gdb is codesigned - see taskgated(8)) I tried to add key chain like this; http://ntraft.com/installing-gdb-on-os-x-mavericks/ and this: https://sourceware.org/gdb/wiki/BuildingOnDarwin And restart my computer. But the problem is

问题 My Rails development IDE is Aptana Studio 3.0.5, running on Windows. The applications runs on Apache + ModRails (Phusion Passenger) on a separate CentOS Linux machine. I have both Rails 2.x and 3.x applications. I would like to be able to use the debugger in Aptana Studio (connect to the running application remotely). There are apparently some provisions for this, but I was unable to figure out what I need on the server side (in my Rails application configuration) I've tried this: Using Rack:

问题 I have an Oracle Db with stored java procedures, which I load new procedures here and then. I would like to be able to debug these java procedures, with a same debug methodology like setting the App server in Debug mode. is it possible? how can I do that? Thanks 回答1: I think you'll want to use JDeveloper which you can also use to debug the app server. It's not as good an IDE as, well, almost any other IDE, but it works well enough for debugging tasks. 回答2: The Oracle JDeveloper has support

问题 Recently I have upgraded to Jest 23.x.x, using the same VSCode debugging configuration as in Jest 22.x.x, I get weird behaviors: breakpoints are moved, and you cannot really debug (not hitting the real line of code). If I downgrade to 22 everything works as expected. Is there any breaking change or update from 22 to 23 to be aware of for this case? My vscode debug launch configuration { "version": "0.2.0", "configurations": [ { "type": "node", "request": "launch", "name": "Jest All", "program
