不同预设 USING THE DIFFERENT PRESETS

不同的预设命名都是不同的，开头除了N，之外还有C，F之类，上面演示中N代表的是 Nikon。其他不同字母代表意义如下：

C - Canon
F - Fuji
L - Leica
N - Nikon
O - Olympus
S - Standard
SO - Sony

相同预设不同版本 FILM PRESET VERSIONS

每一种预设都包含多种版本，用来适应曝光，光照等等因素的影响。每一种胶片模拟都有一个”Normal”的版本，以他的名字命名，不包含任何符号后缀，比如”C - Kodak Portra 400”。

包含+，++，+++符号

包含+符号的版本展示更多的颗粒感，颜色更加强烈(gritter, more aggressive)。通常情况下这些版本产生更多的色调(color toning),阴影(fading),和颗粒(grain)。这些版本产生的效果通常相当于曝光不足，和(scanning variations due to non- daylight white balance conditions at the scene.)

包含-，–，—符号

带-号的预设提供Normal预设较轻柔的版本。通常情况下，这些预设调低对比度，降低颗粒感。

UC,NC,VC 含义

VSCO Film 02 中包含内容， UC 是 “Ultra Color”缩写，提供了合适的色彩饱和度（improved color saturation）和丰富的细节（details with fine grain）。 NC 是 “Natural Color”缩写，适合于低对比度环境（low contrast situation）。 VC 是 “Vivid Color”缩写，适合于中等对比度照片（medium contrast images）。

HC

HC是“High Contrast”的缩写，这些版本提供更加醒目的结果。他们达到的效果和通过工具栏的Contrast滑块调整的效果不一样。

ALT

根据官方的文档, VSCO Film 03 中因为 instant films 的效果和拍摄当时的环境相关， VSCO 为了尽量模拟当时的环境，所以每种滤镜都有不同的版本，ALT 版本就是在其他 + 或者 ++ 版本都无法表现的时候的 Alternative 版本。

轻单体验

最近整理轻单的内容，发现了之前整理过的一些关于轻单的想法，现在就当是备份吧。原单内容部分由复制他人轻单内容而来。轻单早期是有类似Github fork的复制轻单功能的，后来去掉了。

##够“轻”，但不够简“单”

轻，是我知道可以看什么，不够简“单”，是我不知道该发布什么。知乎/Quora以问题为切入口，引导UGC；豆瓣以图片/电影等内容评论为切入口，来引导；Pinterest以图片收集为切入口，来引导收集整理；轻单，只提供了新的类容发布形式，却没有给出好的内容发布引导。大类别分类，贪大求全，定位不明，其实也是形式创新局限的表现。 “显性内容决定产品气质”，目测又是一个互联网蝗虫的小圈子玩物（虽然有问题，但写List确实是喜闻乐见的形式）

From:qdan

##列表形式在早期使用轻单的时候就是不知道写什么内容，对于列表这样的一个形式无意中对内容有了较大的限制。而反过来列表的形式又给予了内容更多的整理。轻单内容用来做分享，用来整理个人知识是很好的，当你真正理解这样的一个形式之后，对自己还是他人都是很有帮助的，就像我一直订阅的台湾一位作者的博客—-电脑玩物，其实说白了，作者很大一部分内容都是整理列表—-旅行你需要的App，10大素材网站等等。只是作者通过博客，以列表的形式分享了出来。而我们平时如果学会了这样的一种方法，对个人知识的整理是大有益处的。比如我自己学习Vim，Git在初期看了很多的资料，有段时间会很混乱，而如果一段时间之后整理自己学到的知识，并且用列表的形式分享出来会得到更好的理解。就像上面提到的一样，轻单没有引导UGC，因此新用户会完全找不到主题，或者内容。而我之前也发过一个轻单说“豆瓣无所不在的豆列对轻单是不是一种威胁”，里面提到我会用豆瓣列表去整理看过的电影，会用网易云音乐去整理喜欢的歌曲，而订阅源的列表分享我会用InoReader集成的功能。定期的整理对自己知识体系的形成会有很大的帮助。而如果想要与别人分享，轻单，我说列表，这样的形式对读者有很大的帮助。回想起来豆瓣在全站推广豆列，Google+更新Collection功能，是不是对列表这种形式的认可呢？

##复制列表由上，引出了轻单早期的“复制轻单”功能，我一直认为这样的一个功能是Github fork的延伸，我觉得我可以使用复制轻单这样的功能给原始轻单添加更多内容，并且分享出来。而现实中“复制轻单”这个功能并没有很多的人使用，所以后来这个功能也就消失了。

##总结轻单的创业已经告一段落，开发团队也已经解散了。对于我这样的用户来说，改变并不是很大，我依然用着List这样的形式来写下这样一篇总结，我依然还是用着很多的List来整理方方面面。但是对于一个产品来说，轻单算是一个终结了，期待有更多的新想法的产生，并由此诞生出伟大的产品。

How to Write a Git commit message

曾经收藏过的一篇文章 How to write a Git commit message，今天无意中点开却发现网站无法访问，故而使用 Google Cache 恢复该文。后来发现作者网站虽然无法访问，但是作者将网站开源了。

Introduction: Why good commit messages matter

If you browse the log of any random git repository you will probably find its commit messages are more or less a mess. For example, take a look at these gems from my early days committing to Spring:

$ git log --oneline -5 --author cbeams --before "Fri Mar 26 2009"

e5f4b49 Re-adding ConfigurationPostProcessorTests after its brief removal in r814. @Ignore-ing the testCglibClassesAreLoadedJustInTimeForEnhancement() method as it turns out this was one of the culprits in the recent build breakage. The classloader hacking causes subtle downstream effects, breaking unrelated tests. The test method is still useful, but should only be run on a manual basis to ensure CGLIB is not prematurely classloaded, and should not be run as part of the automated build.
2db0f12 fixed two build-breaking issues: + reverted ClassMetadataReadingVisitor to revision 794 + eliminated ConfigurationPostProcessorTests until further investigation determines why it causes downstream tests to fail (such as the seemingly unrelated ClassPathXmlApplicationContextTests)
147709f Tweaks to package-info.java files
22b25e0 Consolidated Util and MutableAnnotationUtils classes into existing AsmUtils
7f96f57 polishing

Yikes. Compare that with these more recent commits from the same repository:

$ git log --oneline -5 --author pwebb --before "Sat Aug 30 2014"

5ba3db6 Fix failing CompositePropertySourceTests
84564a0 Rework @PropertySource early parsing logic
e142fd1 Add tests for ImportSelector meta-data
887815f Update docbook dependency and generate epub
ac8326d Polish mockito usage

Which would you rather read?

The former varies wildly in length and form; the latter is concise and consistent. The former is what happens by default; the latter never happens by accident.

While many repositories’ logs look like the former, there are exceptions. The Linux kernel and git itself are great examples. Look at Spring Boot, or any repository managed by Tim Pope.

The contributors to these repositories know that a well-crafted git commit message is the best way to communicate context about a change to fellow developers (and indeed to their future selves). A diff will tell you what changed, but only the commit message can properly tell you why. Peter Hutterer makes this point well:

Re-establishing the context of a piece of code is wasteful. We can’t avoid it completely, so our efforts should go to reducing it [as much] as possible. Commit messages can do exactly that and as a result, a commit message shows whether a developer is a good collaborator.

If you haven’t given much thought to what makes a great git commit message, it may be the case that you haven’t spent much time using git log and related tools. There is a vicious cycle here: because the commit history is unstructured and inconsistent, one doesn’t spend much time using or taking care of it. And because it doesn’t get used or taken care of it, it remains unstructured and inconsistent.

But a well-cared for log is a beautiful and useful thing. git blame, revert, rebase, log, shortlog and other subcommands come to life. Reviewing others’ commits and pull requests becomes something worth doing, and suddenly can be done independently. Understanding why something happpened months or years ago becomes not only possible but efficient.

A project’s long-term success rests (among other things) on its maintainability, and a maintainer has few tools more powerful than his project’s log. It’s worth taking the time to learn how to care for one properly. What may be a hassle at first soon becomes habit, and eventually a source of pride and productivity for all involved.

In this post, I am addressing just the most basic element of keeping a healthy commit history: how to write an individual commit message. There are other important practices like commit squashing that I am not addressing here. Perhaps I’ll do that in a subsequent post.

Most programming languages have well-established conventions as to what constitutes idiomatic style, i.e. naming and formatting and so on. There are variations on these conventions, of course, but most developers agree that picking one and sticking to it is far better than the chaos that ensues when everybody does their own thing.

A team’s approach to its commit log should be no different. In order to create a useful revision history, teams should first agree on a commit message convention that defines at least the following three things:

Style. Markup syntax, wrap margins, grammar, capitalization, punctuation. Spell these things out, remove the guesswork, and make it all as simple as possible. The end result will be a remarkably consistent log that’s not only a pleasure to read but that actually does get read on a regular basis.

Content. What kind of information should the body of the commit message (if any) contain? What should it not contain?

Metadata. How should issue tracking IDs, pull request numbers, etc. be referenced?

Fortunately, there are well-established conventions as to what makes an idiomatic git commit message. Indeed, many of them are assumed in the way certain git commands function. There’s nothing you need to re-invent. Just follow the seven rules below and you’re on your way to committing like a pro.

The seven rules of a great git commit message

Keep in mind: This has all been said before.

Separate subject from body with a blank line
Limit the subject line to 50 characters
Capitalize the subject line
Do not end the subject line with a period
Use the imperative mood in the subject line
Wrap the body at 72 characters
Use the body to explain what and why vs. how

For example:

Summarize changes in around 50 characters or less

More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of the commit and the rest of the text as the body. The
blank line separating the summary from the body is critical (unless
you omit the body entirely); various tools like `log`, `shortlog`
and `rebase` can get confused if you run the two together.

Explain the problem that this commit is solving. Focus on why you
are making this change as opposed to how (the code explains that).
Are there side effects or other unintuitive consequenses of this
change? Here's the place to explain them.

Further paragraphs come after blank lines.

 - Bullet points are okay, too

 - Typically a hyphen or asterisk is used for the bullet, preceded
   by a single space, with blank lines in between, but conventions
   vary here

If you use an issue tracker, put references to them at the bottom,
like this:

Resolves: #123
See also: #456, #789

1. Separate subject from body with a blank line

From the git commit manpage:

Though not required, it’s a good idea to begin the commit message with a single short (less than 50 character) line summarizing the change, followed by a blank line and then a more thorough description. The text up to the first blank line in a commit message is treated as the commit title, and that title is used throughout Git. For example, git-format-patch(1) turns a commit into email, and it uses the title on the Subject line and the rest of the commit in the body.

Firstly, not every commit requires both a subject and a body. Sometimes a single line is fine, especially when the change is so simple that no further context is necessary. For example:

Fix typo in introduction to user guide

Nothing more need be said; if the reader wonders what the typo was, she can simply take a look at the change itself, i.e. use git show or git diff or git log -p.

If you’re committing something like this at the command line, it’s easy to use the -m switch to git commit:

$ git commit -m "Fix typo in introduction to user guide"

However, when a commit merits a bit of explanation and context, you need to write a body. For example:

Derezz the master control program

MCP turned out to be evil and had become intent on world domination.
This commit throws Tron's disc into MCP (causing its deresolution)
and turns it back into a chess game.

This is not so easy to commit this with the -m switch. You really need a proper editor. If you do not already have an editor set up for use with git at the command line, read this section of Pro Git.

In any case, the separation of subject from body pays off when browsing the log. Here’s the full log entry:

$ git log
commit 42e769bdf4894310333942ffc5a15151222a87be
Author: Kevin Flynn <kevin@flynnsarcade.com>
Date:   Fri Jan 01 00:00:00 1982 -0200

 Derezz the master control program

 MCP turned out to be evil and had become intent on world domination.
 This commit throws Tron's disc into MCP (causing its deresolution)
 and turns it back into a chess game.

And now git log --oneline, which prints out just the subject line:

$ git log --oneline
42e769 Derezz the master control program

Or, git shortlog, which groups commits by user, again showing just the subject line for concision:

$ git shortlog
Kevin Flynn (1):
      Derezz the master control program

Alan Bradley (1):
      Introduce security program "Tron"

Ed Dillinger (3):
      Rename chess program to "MCP"
      Modify chess program
      Upgrade chess program

Walter Gibbs (1):
      Introduce protoype chess program

There are a number of other contexts in git where the distinction between subject line and body kicks in—but none of them work properly without the blank line in between.

2. Limit the subject line to 50 characters

50 characters is not a hard limit, just a rule of thumb. Keeping subject lines at this length ensures that they are readable, and forces the author to think for a moment about the most concise way to explain what’s going on.

Tip: If you’re having a hard time summarizing, you might be committing too many changes at once. Strive for _atomic commits_ (a topic for a separate post).

GitHub’s UI is fully aware of these conventions. It will warn you if you go past the 50 character limit:

gh1

And will truncate any subject line longer than 69 characters with an ellipsis:

gh2

So shoot for 50 characters, but consider 69 the hard limit.

3. Capitalize the subject line

This is as simple as it sounds. Begin all subject lines with a capital letter.

For example:

Accelerate to 88 miles per hour

Instead of:

accelerate to 88 miles per hour

4. Do not end the subject line with a period

Trailing punctuation is unnecessary in subject lines. Besides, space is precious when you’re trying to keep them to 50 chars or less.

Example:

Open the pod bay doors

Instead of:

Open the pod bay doors.

5. Use the imperative mood in the subject line

Imperative mood just means “spoken or written as if giving a command or instruction”. A few examples:

Clean your room
Close the door
Take out the trash

Each of the seven rules you’re reading about right now are written in the imperative (“Wrap the body at 72 characters”, etc).

The imperative can sound a little rude; that’s why we don’t often use it. But it’s perfect for git commit subject lines. One reason for this is that git itself uses the imperative whenever it creates a commit on your behalf.

For example, the default message created when using git merge reads:

Merge branch 'myfeature'

And when using git revert:

Revert "Add the thing with the stuff"

This reverts commit cc87791524aedd593cff5a74532befe7ab69ce9d.

Or when clicking the “Merge” button on a GitHub pull request:

Merge pull request #123 from someuser/somebranch

So when you write your commit messages in the imperative, you’re following git’s own built-in conventions. For example:

- Refactor subsystem X for readability - Update getting started documentation - Remove deprecated methods - Release version 1.0.0

Writing this way can be a little awkward at first. We’re more used to speaking in the indicative mood, which is all about reporting facts. That’s why commit messages often end up reading like this:

- Fixed bug with Y - Changing behavior of X

And sometimes commit messages get written as a description of their contents:

- More fixes for broken stuff - Sweet new API methods

To remove any confusion, here’s a simple rule to get it right every time.

A properly formed git commit subject line should always be able to complete the following sentence:

If applied, this commit will your subject line here

For example:

If applied, this commit will _refactor subsystem X for readability_
If applied, this commit will _update getting started documentation_
If applied, this commit will _remove deprecated methods_
If applied, this commit will _release version 1.0.0_
If applied, this commit will _merge pull request #123 from user/branch_

Notice how this doesn’t work for the other non-imperative forms:

If applied, this commit will _fixed bug with Y_
If applied, this commit will _changing behavior of X_
If applied, this commit will _more fixes for broken stuff_
If applied, this commit will _sweet new API methods_

Remember: Use of the imperative is important only in the subject line. You can relax this restriction when you’re writing the body.

6. Wrap the body at 72 characters

Git never wraps text automatically. When you write the body of a commit message, you must mind its right margin, and wrap text manually.

The recommendation is to do this at 72 characters, so that git has plenty of room to indent text while still keeping everything under 80 characters overall.

A good text editor can help here. It’s easy to configure Vim, for example, to wrap text at 72 characters when you’re writing a git commit. Traditionally, however, IDEs have been terrible at providing smart support for text wrapping in commit messages (although in recent versions, IntelliJ IDEA has finally gotten better about this).

7. Use the body to explain what and why vs. how

This commit from Bitcoin Core is a great example of explaining what changed and why:

commit eb0b56b19017ab5c16c745e6da39c53126924ed6
Author: Pieter Wuille <pieter.wuille@gmail.com>
Date:   Fri Aug 1 22:57:55 2014 +0200

   Simplify serialize.h's exception handling

   Remove the 'state' and 'exceptmask' from serialize.h's stream
   implementations, as well as related methods.

   As exceptmask always included 'failbit', and setstate was always
   called with bits = failbit, all it did was immediately raise an
   exception. Get rid of those variables, and replace the setstate
   with direct exception throwing (which also removes some dead
   code).

   As a result, good() is never reached after a failure (there are
   only 2 calls, one of which is in tests), and can just be replaced
   by !eof().

   fail(), clear(n) and exceptions() are just never called. Delete
   them.

Take a look at the full diff and just think how much time the author is saving fellow and future committers by taking the time to provide this context here and now. If he didn’t, it would probably be lost forever.

In most cases, you can leave out details about how a change has been made. Code is generally self-explanatory in this regard (and if the code is so complex that it needs to be explained in prose, that’s what source comments are for). Just focus on making clear the reasons you made the change in the first place—the way things worked before the change (and what was wrong with that), the way they work now, and why you decided to solve it the way you did.

The future maintainer that thanks you may be yourself!

Tips

Learn to love the command line. Leave the IDE behind.

For as many reasons as there are git subcommands, it’s wise to embrace the command line. Git is insanely powerful; IDEs are too, but each in different ways. I use an IDE every day (IntelliJ IDEA) and have used others extensively (Eclipse), but I have never seen IDE integration for git that could begin to match the ease and power of the command line (once you know it).

Certain git-related IDE functions are invaluable, like calling git rm when you delete a file, and doing the right stuff with git when you rename one. Where everything falls apart is when you start trying to commit, merge, rebase, or do sophisticated history analysis through the IDE.

When it comes to wielding the full power of git, it’s command-line all the way.

Remember that whether you use Bash or Z shell, there are tab completion scripts that take much of the pain out of remembering the subcommands and switches.

Git 配置多个 ssh key

Sometimes you need more accounts than one for access to Github or Gitlab and similar tools. For example you can have one account for your projects at home/github and second account for your company/gitlab.

Generate first key

ssh-keygen -t rsa -C "youremail@example.com"

When you see this message

Generating public/private rsa key pair.
Enter file in which to save the key (/home/user_name/.ssh/id_rsa):

Enter unique name, for example:

id_rsa_gitlab

Next, you’ll be asked to enter a passphrase.

So, you have created SSH key for your home/github account, now you can generate SSH key for your company/gitlab account.

Generate second key

Call SSH key generator again with second mail.

ssh-keygen -t rsa -C "your_another_email@example.com"

Enter name for github

id_rsa_github

After all steps you can check that all keys were created.

$ ls ~/.ssh

You should see a similar files list:

id_rsa_gitlab id_rsa_github id_rsa_gitlab.pub id_rsa_github.pub

Create config file

Now you need a config file for organize these keys. Create a config file under ~/.ssh/

$ vim config

Add following to config file:

#gitlab
Host gitlab.com
  HostName gitlab.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/id_rsa_gitlab

#github
Host github.com
  HostName github.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/id_rsa_github

Check connection

Next you can check connection

$ ssh -T git@github.com
Hi einverne! You've successfully authenticated, but GitHub does not provide shell access.

$ ssh -T git@gitlab.com
Welcome to GitLab, Ein Verne (einverne)!

Till now, everything seems ok.

Q & A

Q1. Can one single SSH key be used to push to different Git remotes?

Yes, assuming you are using the one id_rsa.pub or otherwise named public key, together with your private key on all of your development workstations, then simply uploading that one public key to multiple Git hosts will allow you the same access as you currently get from the multiple keys. This will also make your production life a bit easier, without having to manage multiple keys and ensuring you connect with the right one each time you communicate with the server. If you use multiple workstations (ie, home and office), you may also choose to use the same public/private key-pair on each of your local workstations. This further reduces the number of different keys you need to keep track of.

Q2. What is the purpose that we have to generate multiple SSH keys for different remote server?

There is no reason that you have to generate multiple keys for multiple remote Git repository servers, as indicated by the answer to your first question. As Jan Hudec has mentioned though, the reason one might choose to use different keys for different Git repositories, would be for an additional layer of security or management control.

Q3. 如果遇到权限问题，可能是新建的 config 文件权限问题

ssh -T git@gitlab.com
Bad owner or permissions on /home/einverne/.ssh/config

比如遇到上述问题，需要修改一下 config 文件权限

chmod 600 ~/.ssh/config
chown $USER ~/.ssh/config

YAML 学习笔记

YAML 格式的文件在 Jekyll 的时候接触到，Jekyll 的配置文件就是 YAML。Jekyll 本身由 Ruby 写成，而 Ruby 本身和 YAML 有着方方面面的联系，Ruby 的配置文件约定是 YAML。同时，YAML 还是 Ruby 的文本序列化格式。

YAML 是一个可读性高，用来表达资料序列的文件格式。YAML 是”YAML Ain’t a Markup Language”（YAML 不是一种标记语言）的缩写¹ 。在开发的这种语言时，YAML 的意思其实是：”Yet Another Markup Language”（仍是一种标记语言），但为了强调这种语言以数据做为中心，而不是以标记语言为重点，而用反向缩略语重新命名。

空格缩进和 JSON 选项

YAML 文件格式主要集中于空格与缩进的概念，它用于指出数据的层次结构 – 而不是使用 XML 嵌套标记或 JSON 的大括号（{}）和方括号（[]），实际上，它是 JSON 的一个超集，因此，在使用的时候，你可能需要采用 JSON 风格的语法来跳出空格流，它的创始人将其形容为“为所有编程语言提供人性化的数据序列化标准²”，其重点是人性化。

世上有很多的数据结构，但是都可以归结到三种最基本的结构(primitives)：mappings (hashes/dictionaries), sequences (arrays/lists) and scalars (strings/numbers). 有了这三种基本结构，绝大部分的编程语言都能够使用 YAML 了。

YAML 可以被用来作为：configuration files （配置文件）， log files（日志文件），interprocess messaging（进程间通信），cross-language data sharing（跨语言数据交换），object persistence（对象持久化）和 debugging of complex data structures（复杂数据结构的调试）。当数据能够容易的被读懂的时候，任何事情都会变得简单。

YAML 的目标

The design goals for YAML are³, in decreasing priority:

YAML is easily readable by humans.
YAML data is portable between programming languages.
YAML matches the native data structures of agile languages.
YAML has a consistent model to support generic tools.
YAML supports one-pass processing.
YAML is expressive and extensible.
YAML is easy to implement and use.

YAML 结构组件

YAML 的结构：hash，list 和 block literal

YAML 举例，一般扩展名为.yaml，也可以为.yml，比如：John.yml

name: John Smith
age: 37
spouse:
  name: Jane Smith
  age: 25
children:
  - name: Jimmy Smith
	age: 15
  - name: Jenny Smith
	age 12

语义介绍：John 今年 37 岁，有一个幸福的四口之家。两个孩子 Jimmy 和 Jenny 活泼可爱。妻子 Jane 年轻美貌。

值得注意的是字符串不一定需要双引号，当然如果强行添加双引号也可以。比如 "name: "John Smith" 同样也是可以的。

sequence

也可以叫做 list/array ，数组，列表，清单等等

使用-表示 list

- Mark McGwire
- Sammy Sosa
- Ken Griffey

同样可以使用中括号来在行内表示：inline format, using [] ,

[Mark McGwire, Sammy Sosa, Ken Griffey]

二维数组，或者数组中包含数组可以写成

- [name        , hr, avg  ]
- [Mark McGwire, 65, 0.278]
- [Sammy Sosa  , 63, 0.288]

map

或者叫做 hash/dictionary ，键值对,散列,哈希，字典等等。使用:表示，以:分割 key:value

hr:  65    # Home runs
avg: 0.278 # Batting average
rbi: 147   # Runs Batted In

使用大括号来在行内表示 inline format, using {} ,

{hr: 65, avg: 0.278, rbi: 147}

hash 中包含 hash 可以写成这样：

Mark McGwire: {hr: 65, avg: 0.278}
Sammy Sosa: {
	hr: 63,
	avg: 0.288
  }

散列的 key 值可以不为字符串，比如

0.25: a float key

key 的值也可以多行，使用 ? 表示 key 的开始：

? |
  This is a key
  that has multiple lines
: and this is its value

list 和 hash 相互包含

hash 内包含数组：

american:
  - Boston Red Sox
  - Detroit Tigers
  - New York Yankees
national:
  - New York Mets
  - Chicago Cubs
  - Atlanta Braves

数组内包含 hash：

- # one hr
  name: Mark McGwire
  hr:   65
  avg:  0.278
-
  name: Sammy Sosa
  hr:   63
  avg:  0.288

block literal（文字块）

使用|表示文字块,YAML 中字符串不需要包含在引号之内。

literal_block: |
  This entire block of text will be the value of the 'literal_block' key, with line breaks being preserved.
  The literal continues until de-dented, and the leading indentation is stripped.
another_block: >
  This is another block of text

YAML VS XML & JSON

正如你从前面例子中清楚地看到那样，YAML 没有 XML 那么啰嗦了，大部分 YAML 文件内容就是真实的数据，没有了无穷尽的打开和关闭标记列表，在 XML 中，这些标记往往比它们描述的数据还大，YAML 更适合你需要手工维护的数据文件类型。

YAML 没有提供方案或 DTD 概念，因此无法验证文件格式是否符合你的预期，XML 的啰嗦也有它的价值，但总的说来是因为 XML 的成熟使它具有大量额外的工具来验证它的格式，而 YAML 还没有。

JSON 也适合与任何数据，它主要面向提高性能和文件尺寸的大小，因为它几乎不使用空格和关闭标签，然而，JSON 文件的内容增加了复杂性，它的关闭标识就象下地狱一样，这就是 JavaFx 代码（它基于 JSON）中可见的最痛苦的了，在数据文件中，使用 UI 结构使结果更复杂，其复杂程度几乎使文件变得无法理解。

掺和了{}结构和[]清单，使得手工维护大型的 JSON 风格的文件变得相当困难，YAML 使用它的空格缩进方法巧妙地解决了这个问题，当然，无论何时，你都可以切换到 JSON 风格的语法（如在底层节点）。

YAML Validation

作为一种格式，必然是人为规定，也必然存在格式检查工具，下面就是俩：

YAML lint http://www.yamllint.com/
YAML online Parser http://yaml-online-parser.appspot.com/

帝都Uber真实体验

时至今日，快的，百度易到用车，Uber算是已经完全体验到了。短短一两年出租车行业被互联网颠覆，曾经杂乱的出租车市场被快的，Uber等新生的打的应用迅速抢占。在快的，滴滴打车服务进行的同时，专车服务同样如火如荼的开展着。我不是行业人士，我也不曾知道是谁首先推出的专车服务，我只就一普通用户来谈谈我的使用感受。所以有任何错误或者误解的地方尽管留言讨论或者指正。

15/04/12 更正：记忆错误，百度易到用车首次减免40元

12/04/15 今天早上收到Uber邮件，在04/20前使用优惠码 UBERBJGO 可以三次优惠半价。

12/04/20 输入1UBER1WORLD 2TAPS2REQ 3MINSTORIDE

##打车契机

作为一名普通学生，在出行方面不会优先选择出租车，所以基本上打车的情况是在有优惠券的情况下，并且路途比较偏僻，地铁公交等线路比较难走的情况下。最早使用快的是去年在南京的时候，当时因为不熟悉路况，所以就直接用了快的。而百度易到用车和Uber都是今年较晚的时候才使用过。同学家在天通苑，从学校学院路出发如果从五道口走地铁线路的话得60~80分钟才能勉强到，所以在百度易到用车打折力度比较大的时候尝试过。而Uber同样是去同学家玩，从他家到学校的路程。百度的费用在55~65左右（经同学再三检验），减去40元券，实付15~25元；而Uber当时晚上23点打车回来29元，因为有注册新用户30元优惠，实付0元，余额还剩余1元。

##打的流程

打的流程中我觉得最大的区别在于：快的和易到用车是在确定起始地点和目的地点的情况下，司机能确定接不接这个单，而最近使用Uber感觉到是预约到了车才需要告诉师傅目的地，当然你也可以提前输入目的地。但是使用感受上却是司机可以忽略的你打车请求，所以经常可能半天没有响应，当然快的等等的专车除外，而Uber在之前的尝试（3次）中司机响应都非常快，无论是在大半夜（23点），还是在中午（10点），当然今天早上5点钟尝试的时候是没有车辆可以预约的 T_T 。其实快的，易到用车，Uber专车服务响应都还是不错的~但总体感觉上Uber的流程有点怪异，可能是之前使用了前两个而没习惯吧。

##支付流程及价格

当然最终都是走的支付宝，而Uber比较特殊，在最初注册Uber账号时就已经绑定支付宝账号，在完成打车之后可以自动扣款，当时绑定的时候还犹豫了一下，“快捷支付”的支付宝，会不会乱扣款？犹豫之后还是用了，外国公司总不会不讲信誉吧。而快的和易到用车是在完成时用支付宝付款。这两种支付流程导致的最后结果和体验截然不同。Uber最舒心，到达目的地，不用任何操作和司机说拜拜即可，而快的和易到用车都是需要支付完毕再拜拜的，而在网络不好，或者手机电量不足的情况下无法让人忍受，最终的结果就是很多次直接用现金结算了。

##优惠力度

快的，不用说，当时和滴滴开战，各种，相信如果和司机交流过就知道，最初的时候应该打车是不需要花钱的，反而司机还要倒贴前的。而最近快的可能是推广他们的专车吧，一个劲的给我优惠券，听上去力度很大，100的券啦，30的券啦，进去一看全是单张20一张，15一张，还不能叠加的券，哎，坑啊。百度易到用车，当时新用户首次使用立减50，现在不知道还有没有，所以当时很好玩，同学三个来学校用一个电话号码减40，回去用一个电话号码减40 。当时就吐槽百度了，和易到用车合作却没有引入一个账号体系，我承认我用过一次之后我应该不会再想到用它了，除非说再减40。而最后Uber，他有他自己的账号系统，手机邮箱，支付宝，在注册的时候就已经定下来，而注册新用户使用别人的优惠码可以得30元，加入余额，在打车中回优先扣减余额中的钱。单次打车最高减免30元。

##Uber特有

今天同学发现Uber还能平摊费用，所以尝试了一下，过程也比较好玩，我用他的优惠券我得30，他得30，打车15.41公里，行程00:29:10，所以结果是：起步价 0.00 距离 23.17 时间 7.29 小计：30.46元 Uber不计小数点后面的也就是30元然后车费平分：3.2元

总计：33.20元平均每个人16.6

所以我账户里面的钱也没用完，我同学账户里面的钱也没用完，所以神奇的免费做了半个小时的出租车。

所以最后容许我推广一下我的优惠码：re3qx，使用此优惠码，你我都可以获得30元的优惠。
