A new player to the desktop RIA playground?

FreeWizard — Sun, 06 Apr 2008 06:39:00 +0000

With the release of GTalk Lab Ed, an desltop version of GTalk Gadget, Google has showed up its achievement of WebKit engine embedding. After Adobe AIR, Mozilla Prism and some announcement from m$, the search giant maybe also silently joined the Desktop RIA game. Will the gears finally become a Porsche? Let's guess...

Developer Platform Comparison: MySpace vs. Facebook

FreeWizard — Sat, 02 Feb 2008 10:56:00 +0000

MySpace China has opened its developer platform to some beta testers. Similar to Facebook Platform, the dev zone has a list of APIs, some language wrappers(only ActionScript for now) for the API and a test console. Detailed comparison follows:

	Facebook	MySpace
RESTful API	yes	yes (see below)
Query	FQL	n/a
Markup	FBML + FBJS	n/a
Test Console	yes	yes
Authentication	own protocol	OAuth
SDK	15+	1 for now

Generally, I appericiate their picking up of OAuth. But the number of objects and functions accessible via API is too much fewer than Facebook's. OpenSocial API to push activities is still on its way either.

Well, for MySpace, opening is a big step, but too early to give them a bravo.

OAuth Core 1.0 Final in Chinese

FreeWizard — Wed, 30 Jan 2008 09:08:00 +0000

The OAuth protocol enables websites or applications (Consumers) to access Protected Resources from a web service (Service Provider) via an API, without requiring Users to disclose their Service Provider credentials to the Consumers. More generally, OAuth creates a freely-implementable and generic methodology for API authentication.

OAuth协议致力于使网站和应用程序（统称为消费方）能够在无须用户透露其认证证书（译注：如登录密码）的情况下，通过API访问某个web服务（统称为服务提供方）的受保护资源。更一般地说，OAuth为API认证提供了一个可自由实现且通用的方法。

"AIR crash"

FreeWizard — Sun, 11 Nov 2007 07:32:00 +0000

The AIR(Adobe Integrated Runtime) 1.0b2 for win32 crashed on very simple js/html code.

Setting style.display of an iframe(or its container) element to none is dangerous, the workaround cound be setting style.visibility to hidden.

Get the crashing code here: AIRb2CrashSample.air.

It's even my first AIR program. :|

Cool features upcoming in memcached

FreeWizard — Thu, 20 Sep 2007 08:48:00 +0000

Memcached is cool, KISS and powerful. After no-new-release-silence of months, I'm always expecting some new feature from it. Here are things I'm looking forward:

64 bit counter: patch available from Evan Miller
APPEND: patch available from Filipe Laborde
Binary wire protocol: patch and python/java client code available from Dustin Sallings
Atomic operation: patch available from Chris Goffinet
Mass deletion: have not seen the patch yet, but I believe it will not take too long...
Replication? Sounds cool, but a bit complex and not so useful IMHO.
Storage backend? Useful in certain cases, but not so necessary since we have Tugela and NMDB. Ofcoz the world will be more perfect if author of NMDB make a memcached-compatible interface.
Iterating keys/items? Useful or not? Certainly leads to abusing.

For all memcached lovers, we should give our thanks to Facebook, who contributes patches and hosts hackathon. :)
