Consider the following code with your current instruction pointer (the line that will be executed next, indicated by ->) at the f(x) line in g(), having been called by the g(2) line in main(): public class testprog { static void f (int x) { System.out.println (“num is ” + (x+0)); // <- STEP INTO } … Read more

With a debugger you can step through the program assembly interactively. With a disassembler, you can view the program assembly in more detail. With a decompiler, you can turn a program back into partial source code, assuming you know what it was written in (which you can find out with free tools such as PEiD … Read more

(unlike quitting noautocmd is not really required, it just makes vim quit faster). Note: you won’t get information about functions there were deleted before vim … Read more

Everytime docker successfully executes a RUN command from a Dockerfile, a new layer in the image filesystem is committed. Conveniently you can use those layers ids as images to start a new container. Take the following Dockerfile: FROM busybox RUN echo ‘foo’ > /tmp/foo.txt RUN echo ‘bar’ >> /tmp/foo.txt and build it: $ docker build … Read more
We fought a similar problem where Chrome was canceling requests to load things within frames or iframes, but only intermittently and it seemed dependent on the computer and/or the speed of the internet connection. This information is a few months out of date, but I built Chromium from scratch, dug through the source to find … Read more
The short answer to this question is that none of these values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak. Private Bytes refer to the amount of memory that the process executable has asked for – not necessarily … Read more
