VPN Providers Say China Blocks Encryption Using Machine Learning Algorithms 111

An anonymous reader writes "The internet control in China seems to have been tightened recently, according to the Guardian. Several VPN providers claimed that the censorship system can 'learn, discover and block' encrypted VPN protocols. Using machine learning algorithms in protocol classification is not exactly a new topic in the field. And given the fact that even the founding father of the 'Great Firewall,' Fan Bingxing himself, has also written a paper about utilizing machine learning algorithm in encrypted traffic analysis, it would be not surprising at all if they are now starting to identify suspicious encrypted traffic using numerically efficient classifiers. So the arm race between anti-censorship and surveillance technology goes on."

Last Bastion For Climate Dissenters Crumbling 963

Layzej writes "The New York Times reports: 'For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong.' Initially they claimed that weather stations exaggerated the warming trend. This was disproven by satellite data which shows a similar warming trend. Next, solar activity was blamed for much of the warming. This looked like a promising theory until the '80s, when solar output started to diverge from global temperatures. Now, climate contrarians are convinced that changes in cloud cover will largely mitigate the warming caused by increased CO2. The New York Times examines how even this last bastion for dissenters is crumbling. Over the past few years, Several papers have shown that rather than being a mitigating factor, changes in cloud cover due to warming may actually enhance further warming."

I like your community college and AP course suggestions. I got my first B.S. degree in General Engineering from U of Illinois and got out of a few gen eds with AP credit, and then went on to Southern Illinois University at Carbondale for my B.S. in CS and only had to take 2 gen eds there because I had a bachelors degree already. I wish I would have taken more community college courses to get out of 1 or 2 other entry level classes, but too late now. But really, I think it comes down to 2 things: 1) If you are into girls, there will be a very small number in your CS or Engineering courses. Take the gen eds, Meet some people, and expand your circle of friends. 2) If you are going to a top tier school, you will need those gen eds to give you a break from the hard courses. At Illinois, during my toughest semester, I was at the library until it closed almost every night, worked more when i got home, and had an early (9 AM) class every day of the week. I was getting about 4 hours of sleep a night and was miserable. You will be overwhelmed, tired, and miserable if you try to take 15+ hours of credit from a top school.
