ubuntu-14.04

问题 I would like to compile and run C program in sublime text 3 on ubuntu 14.04. Currently the program is being compiled with gcc using sublime text 3 executing a command (see below code), but I was wondering if it's possible to have the program execution output to appear on sublime text console as well.

Uses sqlite3. worker/ - has an index.js file which is a worker for a queue. the web server interacts with this queue using a json API over port 9730 . The worker uses redis for storage.

问题 I'm new to opencv and using ubuntu 14.04 , I'm confused of the difference with opencv , python-opencv , and libopencv , as I have libopencv and python-opencv installed in my system, but I there is no cv interface accessible, so I have to install opencv which is much hard than python-opencv and libopencv . 回答1: libopencv is the debian/ubuntu package while python-opencv is the python wrapper and can be accessed using cv2 interface like COLDSPEED mentioned 回答2: I would like to add to Andika's

问题 I am playing with docker. Now I want to assign IP to container from the same IPs range as my host OS has. My Host has IP address 192.168.1.50 (192.168.1.0/24 network).
