问题 I make a call to Inet4Address.getByName("localhost") expecting to see 127.0.0.1 , but instead I see my IP assigned to my ethernet/airport. If I disconnect my ethernet/airport, I will get the resolution of 127.0.0.1 , but as soon as I connect again it resolves to the IP address of the ethernet/airport. I'm using OSX 10.6.7 and java version "1.6.0_24". My /etc/hosts file has "127.0.0.1 localhost" . Ping localhost in the terminal does resolve to 127.0.0.1. The reason I need this is that I'm

I actually had the same issue earlier today. There are some solutions in this issue on Github, and I will quote some of them here but I

问题 I am using gfortran for an application and running the Fortran through a Matlab mex file. I have noticed that in the current directory when I run the Fortran file, on my mac, it creates a fort.9 or fort.16 file, where the 9 or 16 are some arbitrary number. Recently, I have noticed that these fort. files can be GBs big! Generally they are quite small, like a few kBs. I was just wondering what purpose these files have? And second, is there some error I have in my code that is causing them to be

问题 I am using OpenGL to render a scene in python. My code works perfectly fine on windows but, for some reason, I'm having issues when importing opengl.gl on MacOS. The issue arises when calling from OpenGL.GL import ... in both python scripts and the python console. More specifically here is the exact call in my script: from OpenGL.GL import glGenBuffers, glBindBuffer, glBufferData, \ glGenVertexArrays, glBindVertexArray, glEnableVertexAttribArray, glVertexAttribPointer, \ glDrawArrays,

问题 I have tried using iframe and also video tag and object tag to play the video. In some cases, it plays only the audio from the video, but video doesn't show up. Secondly, the same video file plays well on a separate tab in the browser, but not within my iframe.

Apple has a good documentation of its own for this. https://developer.apple.com/library/mac/documentation/quicktime/conceptual
