我的前端自学计划

Hello World!
我叫Evan,在此立志成为一名优秀的前端工程师。

1. 缘起

我要做前端,因为:
1)个人兴趣爱好上,我喜欢视觉化的编程。程序员简直就是当代巫师!
2)待遇上,前端会比我之前的工作工资要高。我之前的公司不错,但是行业不好;
3)专业技能上,前端技术的可迁移性比较高。一二线城市都可以找到工作;
4)另外,我还有三个个优势:4.1)英语好。我到国外给老外培训过;4.2)家里人支持;4.3)有点闲钱,不算多,但是很养活自己。

2. 自学的难点与解决方案

自学的难点是“自律”与“效率”。
“自律”的关键是要有规律的作息,我的策略是每天跑步。
关于“效率”,我的主要策略是:
1)明确的两个月的时间规划;
2)对外公开主要的时间计划;
3)与世界分享我的知识与项目。

3. 我的时间规划

6月16号前,了解前端技术,制定知识地图,深化计划。

4. 我的分享

1)通过博文来吃透技术难点:
1.1)HTML5
1.1.1)HTML5的API们
1.1.2)SVG动画
1.2)CSS3
1.2.1)LESS还是SASS
1.2.2)display: flex
1.3)JavaScript
1.3.1)EMACScript的标准
1.3.2)Canvas
2)源代码分享:
2.1.)Github:大项目的分享
2.2)在GreasyMonkey等平台上分享脚本;
3)闭源项目:
3.1)H5简历

Documentation of Houhai Sat. Night English Corner (後海(深圳南山)週六夜英語角)

0. This is the documentation of the event “Houhai Sat. Night English Corner”, published on Douban.com by user “IAMEVANHE”.

  1. The event is designed with these principles (and hence actions):
    1. That the event is non-profit
    2. That the event is for advanced English speakers, which is relised by:
      1. That the event is held at a cafe shop, which means most participants can support themselves economically in SZ.
      2. That the description is written in English, which means most participants can read English
    3. That the event is for people living in Nanshan district, not only in Houhai, achieved by:
      1. That The location is near Houhai metro station
    4. The the event is strangers and privacy friendly, made possible by:
      1. The location is a public one, not a private one
      2. There is no need to register for coming to the event
    5. That the event is spontaneous, because:
      1. The timing is fixed
      2. The location is fixed (noted on 2016/09/10: not fixed yet)
      3. The discount from the shop is fixed (noted on 2016/09/10: no discount yet)

    9. Fixed location and timing until further notice.

攝影筆記001:數碼相機原理

 

主流數碼相機利用的是“光電效應”。光電效應是光束照射到金屬表面會使其產生電子的現象。進光量不同,電子所產生的量不同,金屬上的電流與電壓等電學信息也不同。

能將一種信息轉化為另一種信息的設備叫傳感器。能將進光量的信息轉化為電學信息的傳感器叫光電傳感器。主流數碼相機用的(光電)傳感器是CMOS或CCD;CCD比CMOS效果好一點, 造價高一點。我們一般會不嚴謹地將相機裡的x*y(比如6,000*4,000)個橫豎排列的光電傳感器矩陣稱為“傳感器”。“傳感器”裡面的每一個小的光電傳感器對應圖片里的一個像素點。

光電傳感器祗能根據進光量來產生一個對應的電學信息,也就是說,無論你的相機用的是CCD還是CMOS,它們本質上是黑白相機。照片中的顏色是算出來的。一般廠家會在每一個小的傳感器上加上一張能濾掉紅藍綠三原色(也有廠家有其他方案)中的一種的濾鏡,然後通過複雜的算法來“猜測”圖片的原本顏色。

RAW類格式(圖片)文件裡面包含的是傳感器記錄下來的電學信息以及拍攝時用到的參數。(通過Lightroom等進行)後期創作的時候,我們可以修改這些參數(比如色溫等),根據那些電光學信息重新“計算”出畫面。調節參數的時候不會改變那些光電學信息本身,所以說RAW圖片可以“無損”地修圖

British English Accent consumables

To have a British accent, one needs to have a series of “British English Accent” practices in his or her life.

The practices can be using British accent or consuming British accent stuffs.

I can share a few British accent stuffs that I consume. As for the chances of using British accent, well, be creative, and come up with your own methodology.

The stuffs I want to share is called Youtube:

  1. GradeA UnderA
  2. The Economist the magazine
  3. Derren Brown
  4. Queen Elizabeth the second in The British Monarchy
  5. Last Week Tonight with John Oliver
