Keeping www allows hosting static content in cookieless subdomain (without getting new domains) which speeds up page loading.

It is great for building up the hardware side of nation, but not "software" side. The cultural advancement is lagging behind the infrastructure improvement planned by engineers.

It is probably true for platform companies, but in the end cash still rules. With respect, I think Facebook and Tencent are the only few "egoless" big players trying to stay relevant in the paranoid way. They will not give any chance to any threat in their game by copying ideas from startups fast. They know their games.

This tactical approach will only work in existing markets with known customers and known solutions. War is only the tool to achieve the goal, should not be the goal itself.

The valuation of Yahoo assets in Asia is about the same to the current market cap. The bold move is to focus on emerging markets and move headquarter there.

Exactly. Wish that there is an option for users to keep EXIF including geotagging. And give us API to query metadata of pictures (with privacy control).

The article is a little bit misleading. Serving a larger area and serving more people are actually conflicting goals. The latter is always more important in urban area.

Notes: plain text, synced with Dropbox. Personally I use PlainText and 1Password on iPhone/iPad.

As I understand, iPhones get NAT IP (10.x.x.x) in AT&T 3G networks, and outgoing IP shows the gateway location (at least some located in Los Angeles).

From the article, the idea is interesting. But does it mean that it is possible for Stalqer to collect enough data to map AT&T NAT IP to 3G cell ID for location? I though AT&T would randomly assign NAT IP for users' privacy.

In the context, I meant all users in mainland China behind GFW, not Chinese-origin users.

If Inside Facebook's statistics is based on IP, not surprised that there are only few. All Chinese users use proxy/VPN/Tor/SSH to get access from oversea IP.

Trying to setup a private cloud in China because of GFW. UEC with Eucalyptus is nice for leveraging AWS API ecosystem. Hope to make infrastructure in US (AWS) and China as similar as possible.

Anyone has idea how to make it more portable between AMI and UEC KVM image (or UEC Xen image at least)? vmbuilder doesn't seem to solve the problem.

It will be interested to see how Bluetooth 3.0+HS (Bluetooth+WiFi, backed by Broadcom/CSR) and WiFi Direct (My WiFi, backed by Intel) compete with each other.

But I think Bonjour may be the biggest winner if WiFi Direct wins since, unlike Bluetooth profiles, WiFi Direct doesn't include any application layer. Bonjour will fit in the need of service discovery protocol.

Just found CouchDB solving peer-based replication, and it's not structural.

It will probably only work for the next-gen iPhone/iTouch if the rumor is true because the Broadcom WiFi/BT/FM chip needs separate antenna for FM TX/RX. The current WiFi/BT antenna uses 3T switch, no room for FM. No evidence that that antenna exists so far unless it uses earphone cord as antenna (like iPhone Nana). http://www.broadcom.com/collateral/pb/4329-PB00-R.pdf

Also, not FM, Nike+ uses Nordic nRF2402 (BodyLAN/ANT) in TX and Broadcom BCM4325/BCM4329 in RX. I had a screenshot that Apple has a proprietary Bluetooth "sensor" profile for Nike+. http://www.flickr.com/photos/johannchiang/3812514411/

Looks like wiki spreadsheets for structural data with API. Still has limitation that we can't add columns, for example latitude and longitude for restaurants.

On revenue model, it is ok to charge for premium API since it hosts infrastructure. Still hope to have some mechanism like Hg or Git to make open database distributed and synced, so other companies can host the data if they wish.

So far Google Wave is like Google Docs with a better diff if not using extension. It will replace Google Docs before it can even replace Gmail.

Amazon (Joyo in China) don't have Chinese Kindle books. And Kindle doesn't support Chinese characters without hacks yet.

With censorship on print books, China is already the biggest market for eBooks (no copyright though).

At least some people may want touchscreens for first person shooting (FPS) games if touchscreens can handle finger poking. :-)

Dr. Williamson's work is surprisedly very relevant for hackers' startups. His transaction cost economics of markets vs hierarchies explains how startups can compete or sell services to big enterprises.

The trouble is only for developers of native Android app. Not intended, but arguably Google may benefit even more with mess of compatibility problem because eventually only mobile web works across Android phones.

More than crowdsourcing benenfit. Have been thinking that Open Subtitles has chance to transform movie search. Netflix could use Open Subtitles to enhance similarity ranking. Or Apple could let us search quotes in movies and show a few minutes clip around that timeline.

Honestly, it is not as useful as ultrawideband handheld radar under prototyping. Surrounding antenna array is just too excessive.

Two tips for traveling hackers: 1. International roaming of China Mobile/Unicom/Telecom users still don't escape GFW. Roaming data traffic will redirect back to China first. 2. For iPhone users, VPN proxy (L2TP over IPSec or less secure PPTP) is better solution than SSH or Tor. Google those freemium VPN proxy providers.

Kaifu Lee mentioned the same observation in a talk. Chinese news titles usually bear sufficient information that Google news in Chinese doesn't need excerpt as counterpart in English. A Tweet in Chinese could be an essay.

Almost forgot the old days. Arguably pen writing on paper is not very productive for programming and clerk jobs (not necessarily for creative jobs). IMHO, tablets are still better for the applications which don't require too much user inputs.

Because of ergonomics, tablets will be more successful for content consumption type of activities like eBooks or entertainment, primarily on bed or sofa, but not at desk.

All input on touchscreen including innovative gestures still requires users to place their fingers directly onto their eyeballs: either with head looking down or with hands rising up. Both postures are not very productive for programming or desk jobs and can't sustain for long hours.

iPhone is more successful because of light weight and more sensors. To make tablets usage experience better, Internet tethering and sensor sharing via iPhone will help a lot.
