Cast my mind back to the first time I learn programming, around that time I was struggling to figure out all the ingredients about programming through reading books, back then I remember the boring feeling so clearly. Eventally I was obliged to give up the reading and tried to learn programming through directly writing code to resovle tiny problems I’d confronted.

谈起Ubuntu系统，早在很早的时候2011年开始，我就渐渐的将其作为自己的桌面使用了。大概三年前，因为字体渲染和公司使用MacMini的原因，我全方位的切换成了用MacOS。最近，因为某些契机，我重新安装使用了Ubuntu。三年多不见，Ubuntu在我看来，变得是更加好用了。从某种角度来说，Macos与Windows都难媲美他了。或者说，Ubuntu独有的开放风格，将他的使用性提升到了MacOS和Windows因为自身原因不能轻易企及的程度，就如移动时代的Android，只是他们际遇不同，结果不同罢了。

Take a bite of racket’s Local Binding, at the first sight we might already acquire the gist about the usage of define. And then it will come to us with let and for, both of them can be used for loops.

Most recently, I’m very passionate about chinese classical culture. If we take a deep look at the core of chinese culture, we are going to notice all of them include Traditional Chinese Medicine and 24 solar terms and even the way how ancient chinese recording time as their calendar, which is a mix of solar calendar and lunar calendar, are derived from Yijing. In a way, we can say that almost all the chinese things are built on the top of ideas of Yijing, although to this day the importance of it has been diminished by the developing of modern western science.

Recently I extract my code from a former project rainbow-delimiters to scribble-rainbow-delimiters, which is useful for reading code on HTML page generated by Racket’s Scribble.

Recently I have been in the project to develop Wechat Mini programs, and when it comes to the part of decrypting data, I find out there does not exist a Ruby Gem for this although the Wechat official provides code sample but it is only for Python/PHP/C++. So I decided to resemble the Python source code and write a Ruby Gem based on it.

Recently I received an email of a github comment on a Racket Package of mine named http-client, which was announced to release by my post of Announcing the release of http-client. Until then, I realized there really exist someone using my packages except me. This also make me realize I already came to the point to fathom out the design of Racket’s package version that I tried before and abandoned because of being short on time, and I should commit to add versions to my packages.

I’m writing this post to announce the release of a new Racket package called Qweather, the source code of it is at: https://www.github.com/yanyingwang/qweather.

从小学到中学阶段对写作的感兴趣所引发出来的对汉语的语言的特征感知，到工作之后作为一个程序员从事编程工作对编程语言特征的感知，所引发了我的思考进而写过一篇《由汉语编程所想到的》的文章零零碎碎的去阐述对中文编程，即是以汉语作为编程语言的元语言来进行编程，这件事情的意义的一些粗略看法。

I’m writing this post to announce the release of a new web browser plugin/extention/add-ons called Rainbow Delimiters, the source code of it is at: https://www.github.com/yanyingwang/rainbow-delimiters.
