Awesome! We now identified someone, other than our own politicians, as an alternative who can be blamed for all the problems that have undesirable effects...
Here we might be able to get a glimpse into part of the problem that the US is having with its immigration system, that certain jobs are linked directly with certain immigration status (in a sense of semantic interdependence). And thus, whenever someone who is a current US citizen loses his job, entirely (e.g. layoff) or partially (e.g. wage cut or reduced working hours), then an assumption based on equivalence arithmetic can easily arise for him that the part of the job he loses would be occupied by another person, who is very likely an immigrant, due to that 2nd degree link (from his perspective in reasoning) between job and immigration status. But the root cause for his job loss can be much more complicated (if we thinks a bit harder), and more real, than someone who was born in another country and fresh-off-boat took that job away (or stole, if the process was not a concrete thing that could be touched or seen)...Then suspicion, hatred, and sometimes even aggressiveness naturally follow...
But the job market, in its traditional sense, can still shrink, as long as there is increasingly more automation and growing average productivity in our society, even if we chase away all the workers born outside the United States who are not US citizens, and build a wall to create a certain physical separation between us and them. But would we hate and become aggressive towards our new machines and our more productive way of working? Sometimes we would...But it's still much easier to do that towards a living person, especially when he is more vulnerable, legally, than us on our land...
Perhaps the most interesting point here is whether such exclusion, expulsion or isolation could eventually solve our problem...Admittedly, they really work sometimes, for us, and for certain other nations throughout the history, for this or other problem or "question" -- and this indeed is our problem (or at least we have a share in the overall situation) -- and perhaps it's not our responsibility to worry about what that would leave those who are not the "same" as us to...
But is this really the best solution? And best in what sense, and best for whom?
i remember reading another report by washington post on this issue a year ago...i am posting the report link here and perhaps it could provide us with a bit more details regarding the problem...
news title: China used to harvest organs from prisoners.
Under pressure, that practice is
finally ending.

I don't really understand what kind of scientists would do such researches to help the government carry out the censorship more efficiently, over their fellow people...it's either those intellectuals have no brain, or no heart...
this is correct, SS is on the radar and is not as dependable as it used to be, there is a variant of SS that is said to be an improved version but it is still not 100% dependable.
FYI, the great fire wall engineers have already found ways to inspect packets sent through OpenVPN...
A couple of weeks ago, I was asked by a friend who was traveling in China at the time to set up a VPN for him so he could use Gmail and other Google services there...I went for the easy way and used the OpenVPN for him, but to our disappointment, with that VPN tunnel, he still could not access google search page while many other pages on other domains were fine...I spent a few hours trying to figure out why, and then I came across these discussion,
My friend and I haven't experimented further; but I think one way that might work is to chain multiple VPNs or perhaps obfuscate your protocol a bit (i.e. make some minor customization yourself)...
It isn't that they need to inspect the contents of the packets, tcp and udp flow analysis will reveal VPN traffic patterns even if the crypto is perfect. What I've seen reported is that people using openvpn see it work for a while, then increasing latency and packet loss, then eventually total lack of ability to move traffic between the two endpoint IPs.
But if the government completely blocks out VPN uses in the country, lots of international business operating there will suffer and then they will complain, which is not something the government can ignore (at least not always)...VPN whitelist could be a solution, but I don't know how well that is implemented (if it has been implemented) -- not to mention keeping a perfect consistent whitelist at that scale would be difficult...in addition, there is always some false positive/negative in their flow pattern analysis -- those are statistical approaches after all...so there is some grey area here...
Anyway, back to that openvpn experiment I did with my friend, many websites were still accessible with my openvpn tunnel -- although Google was not among those sites -- this seems to imply that they were doing some package semantic analysis (i.e. deep packet inspection)...
Yes, I heard that the Great Fire Wall in China treats network traffic differently when one is on T-mobile data roaming...A friend of mine could use her T-mobile phone to access google, gmail and instagram in china directly, without using a VPN...But you can only access 2G or 3G network (not 4G) in most of the areas there...
Don't mean to be nitpicky...but I noticed some minor issues in your article, which I will list them below...
* the instructions for CPU are in bare ISA binary code, and not assembly. Although there is generally a 1-1 mapping between assembly and binary code (assuming they are well-formed), but you cannot run assembly code directly on CPU. You have to assemble them into ISA binary code first...
* at this assembly level, their corresponding ISA binary instructions are only atomic with regards to the regular users...but for CPU, the binary code would be broken down into microcode and then they will be executed...
Thank you very much!
Nitpicky readers are the kind of readers I look forward to, since they're the ones that help me learn the most. That's why I thought this site would be a good place to post.
That said, I learned those two things in class, but I see I didn't make them come accross at all. I'll see how to make that clearer.
don't worry about those downvotes...if they want to downvote, then let them downvote...
Just look at those HN karma point votes in the past few years, the upvotes for those really awesome hacking technical articles have been frequently outpaced by those downvotes for those petty trifles...If we take that as a measurement, in a certain aspect, we can see that people's hatred and acrimony grow faster than their kindness and sympathy these days...
so I've stopped worrying about those points...for the knowledge value of their corresponding text, they do not reflect as much as they used to reflect....
Is there any way that we could receive similar settlement compensations from the President of the US for his morning tweets? I personally lost a few thousands of dollars due to the sudden stock/cryptocurrency market crash as a result of his tweets in the past few months this year...
