This is a small demo of how to create a library in Rust and call it from Python (both CPython and PyPy) using the CFFI instead of ctypes
.
Based on http://harkablog.com/calling-rust-from-c-and-python.html (dead) which used ctypes
CFFI is nice because:
- Reads C declarations (parses headers)
- Works in both CPython and PyPy (included with PyPy)
- Lower call overhead than
ctypes

On a recent project, I ran into an issue with Python Selenium webdriver. There's no easy way to open a new tab, grab whatever you need and return to original window opener.
Here's a couple people who ran into the same complication:
- http://stackoverflow.com/questions/17547473/how-to-open-a-new-tab-using-selenium-webdriver
- http://stackoverflow.com/questions/6421988/webdriver-open-new-tab/9122450#9122450
- https://groups.google.com/forum/#!topic/selenium-users/kah4iEPRopc
- ... and many many more.
So, after many minutes (read about an hour) of searching, I decided to do find a quick solution to this problem.
jQuery.extend(jQuery.easing,{easeInOutExpo:function(e,f,a,h,g){if(f==0){return a}if(f==g){return a+h}if((f/=g/2)<1){return h/2*Math.pow(2,10*(f-1))+a}return h/2*(-Math.pow(2,-10*--f)+2)+a}}); |

Watch out, os.IsExist(err) != !os.IsNotExist(err) | |
They are error checkers, so use them only when err != nil, and you want to handle | |
specific errors in a different way! | |
Their main purpose is to wrap around OS error messages for you, so you don't have to test | |
for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and | |
"file does not exist/directory does not exist" |
When setting up (that's immediately when user enables it in settings) Opera VPN sends few API requests to https://api.surfeasy.com to obtain credentials and proxy IPs, see below, also see The Oprah Proxy.
The browser then talks to a proxy de0.opera-proxy.net
(when VPN location is set to Germany), it's IP address can only be resolved from within Opera when VPN is on, it's 185.108.219.42
(or similar, see below). It's an HTTP/S proxy which requires auth.
When loading a page with Opera VPN enabled, the browser sends a lot of requests to de0.opera-proxy.net
with Proxy-Authorization
request header.
The Proxy-Authorization
header decoded: CC68FE24C34B5B2414FB1DC116342EADA7D5C46B:9B9BE3FAE674A33D1820315F4CC94372926C8210B6AEC0B662EC7CAD611D86A3
(that's sha1(device_id):device_password
, where device_id
and device_password
come from the POST /v2/register_device
API call, please note that this decoded header is from another Opera installation and thus contains
