caoxuwen··on Lu Ban's axe and working with your Chinese suppliers
I used it quite a bit when I was in China for things other than messaging. Have to say it was a great experience, it works with literally EVERYTHING. You walk on the street - bam the bagger is using wechat QR code to ask for donation. A large number of normal people I encountered don't even use their wallets anymore - menu on wechat, mobile payment on wechat, taxi on wechat, utility on wechat. It's something that after using it, you know there's no way back.
caoxuwen··on Bitcoin's Academic Pedigree
I think it's very hard for a group of people to coordinate behind a pseudonym that's so high profile.

Genuinely curious, been looking into it recently - what're the problem with unregulated public offering? Things i can think of are insider trading, misleading information, ponzi scheme, etc.

caoxuwen··on Optimizing performance on low-end Android devices
Thanks for the input! I'm a cofounder at Echo. From our experience, one tricky part of Android dev is the garbage collection. For the end users, garbage collection sometimes creates noticeable lag. That's one of the worst experience we want to avoid. So for Echo, it's almost always worth the tradeoff to reuse objects and avoid unnecessary new object creation, which means less garbage collection. But like you said, the middle-age objects could pose some problems in the future. Judging from the past trend, garbage collection will always be one rocky part of the Android land, which was quite a lesson for us when moving from the ios arc world :)
caoxuwen··on Why the Twentieth Century Was Not a Chinese Century
There is a fantastic book - "Why the west rules, for now" that deals with this question (the name sounds quite right-wingish, but it's actually a great history book). I highly recommend anyone interested in this topic to read it.

If I can bring some interesting observations of the author to this discussion, it's that West (including mid east+europe+later america) and East (mostly China+later japan) led at different times. West had a 2000 year head start and reached its peak during Roman empire. East finally caught up around 600 AD and was ahead till the eve of western industrial revolution. Backwardness in some period of history (whether it's in nature resource, technology, social organization), became advantages in others. So you see the power shift constantly happening.

The ultimate reason (obviously i'm doing a huge reduction here) the writer claimed that caused the last shift of power between East and West was simply that America was too far from China. China got the thoughts/technology it needed. Europe found a flood of new problems and solved them with new thoughts/technology.

While I don't completely agree with his arguments, it's nonetheless an interesting and well supported point of view and much better than many other books out there that deals with big history topic (eg. "Guns, Germs and Steel")

caoxuwen··on The Game Of Go: A Programmer's Perspective
I feel in chess it's about concentrating your power with the goal of total elimination of the other side in one battle. With go, there are multiple battles where you make trade-offs - short term vs. long term, territory vs. influence. Focusing on solely one part of the equation is almost always not optimal, yet you can still develop your unique style of play. You would often feel it's not a zero-sum game where both sides are taking what they want(though in the end only one can win). Also with the huge branching factor, go feels more dynamic and fluid.
caoxuwen··on The Game Of Go: A Programmer's Perspective
Go is a fantastic game. It's also a great analogy of the eastern philosophy with its emphasis on balance and long-term strategic vision.
caoxuwen··on Get advice on YC from alums
We invited a few YC alums to answer questions on Askolo - ask them about experiences going through the YC application and interview process, what YC is like from a founders point of view, and anything else you'd like to know. They are not speaking on behalf of YC, but rather to offer personal thoughts and perspectives.

caoxuwen··on Show HN: Q&A for HN users
hi instakill, person/content discovery is a major feature we are working on - it'll probably be out next week. Regarding why you can't see you questions on askee's profile - the askee may have made all unanswered questions invisible (you can do that too in your settings page) or deleted your question. Right now there's a short text under the "ask" box that explains it - we should have made it more obvious.
