旋转木马の阶梯

insanely great, snow

加拿大的冬天，一向被大雪覆盖。地面早在十一月已被大雪覆盖。夏洛特敦的冬天与加拿大的他处并无不同，阴冷多云，白雪纷飞。但大约是因为暖流在旁掠过，气温并不低于内陆省份阿尔伯特、安大略或魁北克。在王子岛上，冬雪一直到四月才结束。

两年在岛上，过着退休般的日子。今天学分已足、工作也告一段落，是时候离开这个地方了。

生活变得很规律，忙得很。

春天的花

春天的确还没来，可脚步近了：雪少了，雨多了，温度升了。

冬天很漫长，但春天快来了。

Ragel状态机生成器

Felix Huang — Thu, 04 Dec 2008 00:28:17 +0000

Ragel可以把正则表达式翻译成有限状态机（FA）的各种语言表示，包括C、C++、Objective-C、D、Java和Ruby。Regular Expression和FA的用途很广，可以用于协议分析、数据解析、词法分析、用户数据校验等。在Ragel的帮助下，写一个atoi的函数非常容易，而且比标准库提供的atoi函数性能要高。

le temps pour l’amour

Whether you believe me or not,
I fell in love, again, fabulously, rationally, and, radically.

May things go well, Amen.

Here’s to the Crazy Ones

Felix Huang — Sun, 24 Aug 2008 18:31:15 +0000

Here’s to the Crazy Ones.
The misfits.
The rebels.
The troublemakers.
The round pegs in the square holes.
The ones who see things differently.
They’re not fond of rules.
And they have no respect for the status quo.
You can quote them, disagree with them,
disbelieve them, glorify or vilify them.
About the only thing that you can’t do, is ignore them.
Because they change things.
They invent. They imagine. They heal.
They explore. They create. They inspire.
They push the human race forward.
Maybe they have to be crazy.
How else can you stare at an empty canvas and see a work of art?
Or, sit in silence and hear a song that hasn’t been written?
Or, gaze at a red planet and see a laboratory on wheels?
We make tools for these kinds of people.
While some may see them as the crazy ones, we see genius.
Because the ones who are crazy enough to think that they can change the world,
are the ones who do.

Think different.
