问题 How can I install and run CasperJS files in Android? Is it possible? I would like to create an equal application droidscript with test functions and execute on a webview. 回答1: CasperJS is built on top of PhantomJS (and SlimerJS). Those are browsers themselves. They cannot be run in a WebView. It may be possible to compile, though I didn't find any documented trials. You should be able to port the PhantomJS API to an Android WebView and then make some adjustments to CasperJS so that it uses

问题 How can I rename many files. Remove the digits at the beginning. I have a Mac. All the files are in the same folder.

问题 I would like to make a bash script that will iterate over different user agent options, open Firefox with the selected user agent, wait for x seconds, and then close, and loop. Is there a command-line option for firefox to specify the user agent? 回答1: There is no flag for this specific purpose, but you can create a set of Firefox profiles, where each profile will specify a particular user agent. There is an about:config option general.useragent.override, which you can specify in the user.js

问题 I'm trying to process images from my camera on my server and get the information after processing on my local machine in real-time. I can get necessary information as terminal outputs on my server, but I can't put this info in my python code on local machine, until my server program is running. I'm tried this code: cmd="sshpass -p 'pass' ssh -Y user@ip -t 'process_image; bash -l'" p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1) for line in iter(p.stdout.readline, b''): print(line

Eclipse-specific instructions: In your project properties, select Java Build Path, then Libraries. Locate the

问题 I'm trying to program a simple "typewriter" effect in C, where text appears one letter at a time with a delay. Here's the function I have: #include <stdio.h> #include <unistd.h> void typestring(const char *str, useconds_t delay) { while (*str) { putchar(*(str++)); usleep(delay); } } The problem is the text doesn't actually appear until a \n is displayed. What am I doing wrong? 回答1: The output to stdout is buffered. Using \n you are forcing a flush. If you want to change this, you will need to
