I am spending a month in Beijing. This week the China Theory Week is under way, the second in a series of annual events bringing graduate students from all over to Beijing for a week of talking about theory.
In October, there will be the China Symposium on Theoretical Computer Science, which is like the Theory Week but with older people.
Yesterday I spoke about my work on spectral methods for Max Cut, on which there have been a couple of advances since I posted about it here: (i) Moses Charikar has improved my analysis of the recursive algorithm, and (ii) I am now able to handle (in a complicated way and with very poor bounds) the “Max Cut Gain” problem.
I will write about it here, but first I will have to find out how to do it. WordPress is blocked, I have not been following all the explanations about “tunneling” and “proxy servers,” and so far the only way I have found to post here (open a remote desktop on a Berkeley computer) is excruciatingly slow and not conducive to write math (which needs previews etc.). Meanwhile a revised paper is available online.

I was in Tsinghua for three weeks in May. What I found out was that they actually had (temporally?) unbanned most of the websites – though I don’t remember if WordPress was one of those. How’s the banning going nowadays, seems to be back?
I found a simple way to tunnel firefox on windows, then though, so probably some sites were still banned:
- open putty (may be works with some other ssh clients too), in opening
screen left select SSH -> tunnels
Add new forwarded port:
source port: 7070 (say)
Please greet the people there – esp Christophe, Elad, Andrej, Amy Wang, all the secretarial staff!
destination: anything that allows ssh forwarding (your work machine)
Click on ‘dynamic’
press add
connect now to some site
- after doing that with putty, in firefox take ‘configure how firefox connects
to the internet’
manual proxy, socks host 127.0.0.1, port 7070 (say)
Tis should work.

It seems to work.

Well, some of my paragraphs were misordered but I am sure you can decrypt my comment.
