How to Avoid Even More of the Common (but Deadly) MySQL Development Mistakes

“Why can’t I just save my data to a file?”

Using an SQL database seems so complex to get right, and for good reason. The variety of data-driven applications is practically limitless, and as project requirements change, we find ourselves taking shortcuts and adopting bad habits. But there are proven methods to understanding how to develop and manage data in a scalable and reliable way. This talk shows you some of these methods, including:

• How to optimize a database application with partitioning and sharding.
• How to avoid the secret security vulnerability that you’re probably guilty of.
• How to use optimizer hints effectively.

At the end of this webinar, you’ll be more productive and confident as you develop database-driven applications.

Please register for this webinar and join me on July 16!

"The Most Common Habits from more than 200 English Papers written by Graduate Chinese Engineering Students"笔记

本文介绍了中国人在英语写作中常犯的错误，并给出的修改建议；

文章的宗旨是准确表达作者的意思。

避免超长句子

• 一句话表达一个意思；
• 在介绍公式中的大量字母/参数含义时，可以用list代替文本描述

避免用"namely/that is to say"

在一句话里表达意思；

句子主干提前

将句子的主干提前，将修饰的状语(从句)置后，如to、in、for、when等；

Incorrect: Inside the test box, the space was filled with asbestos. Correct: The space inside the test box was filled with asbestos.

用英文单词而不是阿拉伯数字

Incorrect: All 3 studies concluded that the mean temperature should be 30°C. Correct: All three studies concluded that the mean temperature should be 30°C

用"in this study"而不是"In this paper"

in this paper使用次数不多于3次；必要时可以用in this study/research代替

用"by doing this"而不是"by this way"

用有道词典的原声例句功能可以发现，by this way基本没有出现过；改用by doing this；

用"also"而不是"too"

also是书面体，too是口语；

用"are shown in Fig. 2"而不是"are shown as Fig. 2"

在句中用文本描述公式

Incorrect: If the power battery SOC > SOD and the driving torque belongs to the middle load, … Correct: If the power battery SOC is greater than SOD and the driving torque belongs to the middle load, …

句首不用"How to"

Incorrect: How to find the optimal parameter is the main objective. Correct: Determining how to find the optimal parameter is the main objective.

句首不用"Obviously"

Incorrect: Obviously, detecting regimes by means of PMH maps is a novel method. Correct: Detecting regimes by means of PMH maps is a novel method.

句首不用缩写或阿拉伯数字

Android: Avoid passing null as the view root

在做一个应用时把Android SDK从4.4换成6.0，使用LayoutInflater的inflate方法时出现以下情

LayoutInflater.inflate(int resource, ViewGroup root)

参数root为null时，出现warning提示

Avoid passing null as the view root (needed to resolve layout parameters on the inflated layout''s root element)

建议添加

@SuppressLint("InflateParams")

在网上查了，如果改用View的inflate方法root为null就不会出现warning提示

View.inflate(Context context, int resource, ViewGroup root)

avoid

vt.	避开，避免，预防; [法] 使无效，撤销，废止;

[其他]	第三人称单数：avoids 现在分词：avoiding 过去式：avoided过去分词：avoided

Avoid mutating a prop directly子传父报错解决

Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop’s value. Prop being mutated: “drawer”

element-ul抽屉模块的时候经历这样一个错误片段，已解决
错误:避免直接改变属性，因为每当父组件重新渲染时，该值都将被覆盖。相反，请使用基于属性值的数据或计算属性(子组件不可直接修改父组件传递的Prop值，单向数据流，易于监测数据的流动，出现了错误可以更加迅速的定位到错误发生的位置)。

更简单来说呢 就是一个父组件并不是只有你一个子组件，如果每一个子组件都可以修改父组件的值，那么我们需要定位的错误很难统一。

所以我们把修改数据的权限交付给父组件，才能最快以及准确的定位我们的错误，从而保证了数据源的唯一性。

父组件:

子组件:
