计算机专业太难不适合女生学？来看 N 多小姐姐的回应 - 文章 - 伯乐在线
@刘不刘二小姐：没想到"计算机太难不适合女生学"的观点五年前我上大学的时候有，现在都火成这样了还有[二哈]
很多关注我们的小姐姐都冒泡留言，鼓励那位求助的女生。汇总如下：
@澈海情深：计算机女生出来说一句，现在干啥都挺难的。学计算机也没有想象中那么恐怖。感兴趣就学呗。
@眠眠阿卷：选吧，学计算机又不是以后当码农，计算机是个工具，你学了计算机，以后去哪里再读其他专业都受欢迎
@J家蠢萌痴汉夏：怎么会，我就毕业了呀，毕业还是简单的，只要好好听课，也不会挂科的[二哈] 当年高考结束填志愿，五个全是计算机第一顺位，🙊回过头想想也是有勇气啊

A brief dive into 2 times I clearly had no clue what I was doing as a developer
Last week I had a short conversation with coworkers about how we had messed up in our careers. Being so far removed from those mistakes, it was easy to laugh. More than laughs, though, these screw-ups served as powerful lessons for us.
It's important that we share our mistakes so that others can learn from them and maybe feel more comfortable with their own. So here are a couple of my more recent ones.

Your Git Log Should Tell A Story
Have you ever been debugging an annoying new bug and realised that the simplest way to track it down would be to look at what changed in the code since the previous release, where the bug wasn't there?
There are different ways to do this, a quick one is to run git log and to skim through the commit messages looking for something suspicious. That is, if the commit messages tell something useful.
We software developers take a lot of care in crafting readable and efficient code, but too often not enough in writing informative commits. It is not uncommon to see logs like this (fictitious) one:

Learning Git Internals by Example - teohm
After switching to Git from Subversion and Mercurial for a few months, somehow I feel that Git is fundamentally different from Subversion or Mercurial, but couldn't really tell the differences. I often see terms like tree, parent etc. in GitHub, which I have no idea what they actually mean.
So I decided to spent some time to learn Git.
I will try to summarize and publish important stuffs I learned about Git along the way.. but here is the first entry, about Git internals, which helped me to answer how Git is different other source control tools.
To understand the core of Git internals, there are 3 things to we should know: objects, references, the index.

ispell是Unix下的一个拼写(不仅仅是英文)检查工具，同时它也是Emacs用来调用ispell类工具进行拼写检查的插件名称。
之所以说是ispell类工具是因为Emacs的ispell插件不仅仅支持调用ispell来进行拼写检查，也支持调用aspell/hunspell来进行拼写检查。
而且事实上，aspell已经逐渐取代ispell成为主流。

fahd.blog: Writing your own Bash Completion Function
Bash programmable completion is a powerful feature which allows you to specify how arguments to commands should be completed. You do this using thecomplete command. For example, you can set completion up so that when you type the unzip command and hit the TAB key, it only shows completions for files ending with the .zip extension. Similarly, the completion for the ssh command would display hosts taken from your known_hosts file. In this post, I will describe how you can write a custom completion function for a command foo. Bash will execute this function when foo [TAB][TAB] is typed at the prompt and will display possible completions.
Bash uses the following variables for completion:
COMPREPLY: an array containing possible completions as a result of your functionCOMP_WORDS: an array containing individual command arguments typed so farCOMP_CWORD: the index of the command argument containing the current cursor positionCOMP_LINE: the current command line${COMP_WORDS[COMP_CWORD]}. So, how do you build the result array COMPREPLY? The easiest way is to use the compgen command. You can supply a list of words to compgen and a partial word, and it will show you all words that match it. Let's try it out:

String concatenation with Java 8
In summary, Java 8 seems not to introduce new optimizations for String concatenation with the + operator. It means that using StringBuilder manually is still required for specific cases where the compiler or the JIT is not applying magic tricks. For instance, when lot of substrings are concatenated to a String variable defined outside the scope of a loop.
The reason for not optimizing automatically all String concatenations is still a bit obscure to me. Probably, too much information and efforts are required to handle all possible cases safely. After all, that's also a good point to make programmers think about what they write.

I'm trying to become less dumb — by listening to smart people
I'm getting more and more excited about a very simple fact. Listening to smart people, thinking hard about what they had to say, and then regurgitating their ideas in conversations, makes you smarter. It might be seen as untrue, but I think that's the nature of good ideas, they tend to flow from person to person, from a book passage to a reader, from a podcast episode to the listener.

Top 7 Credit Cards For Those With Excellent Credit
If you're in the market for a great cash back rewards cards that also has a long 0% APR, the Discover it Cash Back card is a smart pick. To start, Discover will match the cash back you earn at the end of your first year as a card member. So if you earn $300 in cash back, Discover will match that $300 for a total of $600 cash back! You can really rack up the cash back by earning an ongoing 5% cash back (an effective 10% back your first year after the Cashback Match Bonus) in categories that rotate each quarter you activate (on up to $1,500 in combined purchases, then 1% back) and 1% back on all other purchases. The categories for 2018 include gas stations and wholesale clubs from January to March, grocery stores from April to June, restaurants from July to September and Amazon.com and wholesale clubs from October to December. In addition to all this, cardholders will get a 14-month 0% intro APR on purchases and balance transfers (then it's 13.49% to 24.49% variable), with a 3% balance transfer fee. The Discover it Cash Back card really does have it all – cash back, an extra cash back bonus (2X cashback your first year!), a lengthy 0% intro APR on purchases and balance transfers AND no annual fee.

Log processing, 1. part – architecture overview | YSofters
This article is a first one of planned series focused on log processing, therefore YSoft SafeQ monitoring. It explains goals of log monitoring and intended use cases, as well as requirements for designed architecture. A brief description of high-level view of designed architecture follows, architecture itself will be properly described in one of following articles.
Logs contain information about behaviour of SafeQ deployment, but each log carries only limited local info (such as single Exception). This can directly lead to understanding, what has happened, but sometimes more logs, even from different components, are needed.
The main goal of log processing is to collect all logs to a central location, unify them to single format to simplify their structure, compute additional information, such as duration of a print process, and finally index this info into a database to allow searches and visualizations into graphs.

Exercises in Programming Style | Henrik Warne's blog
In the book club at work, we recently finished reading Exercises in Programming Style by Cristina Videira Lopes. The book consists of a simple program implemented in 33 different programming styles. It is a great way of showing the different styles, and the book was quite popular in the book club. The book is relatively new (it was published in 2014), and I don't think it is as well-known as it deserves to be. So here is a summary and review of it.Read full article from Exercises in Programming Style | Henrik Warne's blog
在Amazon的时候，公司内有大量的组来维护不计其数的service，而service之间的通用通讯方式是公司内部的一个框架，协议是自定的，客户端也是内部的；现在到了Oracle，我看到这个变成了RESTful，也就是说，协议本身变成了最常见和适用的一种。我看到有太多论述RESTful优点的文章了，而实际工作中也确实有所体会，比如接口和报文的可读性好，不需要特制的客户端，上手和调试都比较容易等等。但是，如果看到某个东西被冠以过多正面的评价，就要当心了。我也慢慢地体会到了一些问题。不过，在谈谈我的思考之前，我想先明确一下我对REST的认识，而这点，鉴于历史原因，也是我不太愿意花时间争辩的内容。我认为REST是一种设计和架构的方式，体现了系统响应请求交互的风格，而非接口规约，更不是什么报文协议。
对于RESTful的四种HTTP/HTTPS的方法，我看到不同的工程师有着不同的理解，而这点，是缺少足够明确的约束的。
对于资源名称的定义，也就是RESTful的核心，也不适用于许多问题的解决。我用过SOAP，也用过一些其他的XML协议，REST是更加简洁的一个。如果是针对简单实体的增删改查，RESTful无疑是有效的。换言之，它擅长通用性问题的解决，但是孱弱于特应性问题的处理。但是如果是一个复杂业务的封装，RESTful显得力不从心。这样的封装，之所以不任其发展为通用接口，就是考虑到某些业务的特殊性，而通用接口对于特定场景的优化是不足的。就像一个简单的二维表，一个简单的select-from语句可能就可以解决，但是当业务复杂到多数请求都需要join、filter、map，这就似乎很难用擅长通用性的REST来解决问题了，否则就要创造一大堆不易理解的、不易重用的名词在作为resource了。
前面提到过缺少REST之上更为细致的协议或者规约，这个可以进一步展开说。对于某些基于请求和响应的通用操作，和内部框架+协议的方式比较起来，不太容易统一。比如说鉴权，比如说流控，比如说性能监控，这些东西都是很常用的，但是我看到使用一个专有的内部框架会更方便地嵌入和推广这样的组件，而RESTful的结果就是各个项目组五花八门，对于具体字段的理解也是分歧不少。
最后一个，我想到的是客户端的生成，以前用到的内部框架，可以方便地生成客户端，而客户端的功能也比较强大。但是RESTful了以后，以往的一些客户端丰富的特性都要重头自己实现过，比如说复杂的参数校验，比如一些自动装包解包到业务对象的代码生成等等。事实上，这些工作是不可能省略掉的，没法借助框架完成，就要自己想办法做。我记得以往获知一个service，为了使用客户端，想了解一下schema，很容易就可以得到自动生成的文档，但是现在则完全不能。
基于这些种种的原因，如果从头来过，依然使用RESTful风格的service，为了保持各个service之间的一致性，兴许一个统一的API框架是值得的。我理解速度在如今软件企业中的地位，但是我们总得在和可维护性的博弈中取得一个平衡。
确实软件开发没有银弹，而我自认为对于RESTful不足的思考还是不够深刻，如果你有很好的认识，不妨告诉我。：）

迪米特法则和合成复用原则等， 所以在常见的文章中有表示写六大或七大原则的； 除此之外我还将给出一些其它相关书籍和互联网上出现的原则；
Single-Responsibility Principle, 一个类,最好只做一件事,只有一个引起它的变化。单一职责原则可以看做是低耦合,高内聚在面向对象原则的引申,将职责定义为引起变化的原因,以提高内聚性减少引起变化的原因。
一个对象应该只包含单一的职责，并且该职责被完整地封装在一个类中。（Every object should have a single responsibility, and that responsibility should be entirely encapsulated by the class.），即又定义有且仅有一个原因使类变更。

10 Quick Google Search Tips to Find What You Need Faster
How did we ever get along without Google? With its mix of simplicity and breadth of information, there's little doubt that it's king of the mountain when it comes to search engines.
While most of us use Google for basic search, just under the surface there's a wealth of information to help make your searches more effective. Instead of searching for an airline's website and hunting down flight information there, have Google give it straight to you. Instead of finding a site that tells you when sunrise is, just let Google tell you. From searching within a specific website to finding books by a specific author, Google has it all.
