System design is one of the most important and feared aspects of software engineering. This opinion comes from my own learning experience in an associate architecture course. When I started my associate architecture course, I had a hard time understanding the idea of designing a system.
One of the main reasons was that the terms used in software architecture books are pretty hard to understand at first, and there is no clear step by step guidelines. Everybody seems to have a different approach.
So, I set out to design a system based on my experience of learning architecture courses. This is part of a series on system design for beginners (link is given below). For this one, let’s design the URL shortening service.

The cloud security market grows with increasing threats
Tags: cloudsecurity

Additionally, market research firm Infonetics confirms the strong projected track record. Specifically, Infonetics predicts that revenues from cloud-based security services will skyrocket. Recent estimates predict that the market size will triple by 2017.

As many forms of [cloud security](https://www.cloudanalogy.com/) platforms and solutions adopt cloud-based approaches, ATR research analyst Marie Horton predicts that top priorities for the enterprise cloud will include web security, identity management and security. emails.

Therefore, the cloud computing market as a whole is growing at a rapid rate and will continue to do so. Many studies predict that more than 50% of a server's workload will be virtualized in the cloud in 2014. Additionally, they predict that the total market size will exceed $ 125 billion. This massive growth can be attributed to a massive growth of hackers and cloud threats.

The cloud is aware of many threats and problems. Savvy hackers and cyber attackers take advantage of advanced methods, such as infiltrating a business from the inside out, without being detected by most. Sophisticated hackers are now exploiting the social media accounts or computers of company employees. Malicious applications installed on employee computers are exploited to launch massive attacks on the corporate network. 

For hackers and cyber attackers, cloud infrastructure appears to be a very attractive target. Therefore, before submitting your information to a cloud service provider, it is important to verify the level of security, whether it is or not. Additionally, some companies may be required by regulations to ensure adherence to strict regulations on data security, data privacy, and other compliance policies. When dealing with highly sensitive and confidential information, such as social security numbers, credit card numbers, and medical information, companies must comply with additional regulations. Additionally, organizations that store this highly confidential and sensitive information should be especially concerned about their security measures in the cloud. In addition, all companies must also be vigilant to protect their sensitive customer data, strategy, and vital employee information through [cloud security platforms](https://www.cloudanalogy.com/).
Worst thing about Visual Studio
Tags: csharp
Published: 2020-09-25 12:59:28

As many of you C# / .NET developers know, Microsoft Visual Studio is the IDE of choice for us. It's may even be impossible to build older apps in debug mode with anything else; as it seems to be at my current place of work. I have gotten used to using Visual Studio over the years after a somewhat rocky transition from IntelliJ and Java. But there is one thing that continues to be the bane of my relationship with the IDE -

This is that CTRL + P is mapped to PRINT and not open file like EVERY OTHER IDE EVER CREATED! 

I know the key mappings can be reconfigured, and I did that when I first started at a C# shop but was horribly disappointed when the first time I upgraded (at VS's suggestion) and my mapping was reset.

I ask why, Microsoft? WHY?? I imagine a developer has not needed to print out their code since shortly after the Apollo program shut down, must you be such a slave to tradition? 

Thanks for reading my rant and happy Friday, DEV!

How long until CSS variables will replace CSS-in-JS color enums?
Tags: discuss, javascript, css, react
Published: 2020-09-25 12:55:56

This is a bit of a troll post, but it looks like CSS-in-JS community really wants to have their colors and spacing units and all that stuff defined in JavaScript objects.

However [CSS variables have reached nearly 95% browser adoption](https://caniuse.com/css-variables) and they make many things far easier to do avoiding typical specificity issues, or problems where you do things like `<StyledComponent as={AnotherStyledComponent}>` but end up having different visual end result depending on which component's CSS loaded first.

You could just start throwing out the legacy workaround in CSS-in-JS solutions of declaring variables in JavaScript, but so far I haven't seen community paying attention to this.

So how long does it take for the CSS-in-JS community at large to move to CSS variables? Are there attempts in the community to fix this issue?

#### 📺 029 - Dean Bryen 🎙️ Jason Hand

{% youtube X7KJGoOjrVI%}

Let's take a look at how to secure up our Serverless Applications on Azure. We'll deploy a purposely un-secure app, then we'll wear two hats. First we'll put on our black hat and attack the system to see how an attacker may 'hack' in-secure serverless apps. Then we'll flip over tot he blue team and look at fixing the issues and make our app more robust!

1 small tip to improve your code readability
Tags: webdev, readability, javascript
Published: 2020-09-25 12:10:24

([Kevin Du](https://www.pexels.com/it-it/@kevin-ku-92347) photo on [Pexels](https://www.pexels.com/))

Code readability is important.

When you find yourself in situations like this one:

```javascript
function doSomething() {
  // some code...
  let needToDoALotOfThings = /* test */
  
  if (needToDoALotOfThings) {
    /*

       A good amount of code

    */
  }
}
```

you can refactor it in this way:

```javascript
function doSomething() {
  // some code...
  let needToDoALotOfThings = /* test */
 
  if (!needToDoALotOfThings) return

  /*

     A good amount of code

  */

}
```

or, even better:
```javascript
function doSomething() {
  // some code...
  let needToDoALotOfThings = /* test */
 
  if (!needToDoALotOfThings) throw new Error(/* error message */)

  /*

     A good amount of code

  */

}
```

The difference is **slight** but **significant**. By using this approach, you'll have (at least) 2 advantages:
1. 1 less indentation level, that is always good;
2. Your condition is shrinked in 1 line of code, making the code easier to read in future reviews.

You obviously can't use this approach everywhere, it depends on the situation (as always), but it's a small correction that can save a bit of brain cells to the person that will read that snippet of code in the future.

TestNG Interview Questions for Experienced Professionals
Tags: testing, interview, testinginterview, testng
Published: 2020-09-25 10:29:32

Hello friends! <a href="https://testng.org/doc/">TestNG</a> is one of the most common testing frameworks used in the automated testing suites. In this article, I am sharing 5 of the <a href="https://artoftesting.com/testng-interview-questions-with-answers">top testNG interview questions</a>.


<b>Ques. How can we skip a testNG test case conditionally?</b>
Ans. TestNG provides an exception by the name - SkipException. We can throw this exception inside our conditional statement like this-
<code>@Test
public void testMethod(){
  if(conditionToCheckForSkippingTest)
 throw new SkipException("Skipping the test");
  //test logic
}</code>


<b>Ques. How can we pass parameter to our test script?</b>
Ans. This can be achieved with the help of @Parameter annotation and ‘parameter’ tag in the testng.xml.

&lt;parameter name="sampleParamName" value="sampleParamValue"/&gt;


Sample test script-
<code>public class Test {
   @Test
   @Parameters("sampleParam")
   public void parameterTest(String paramValue) {
      System.out.println("Value of sampleParam is - " + sampleParam);
   }</code>


<b>Ques. How can we run our test cases in parallel?</b>
Ans. In order to run the tests in parallel just add these two key-value pairs-

<code>
parallel="{methods/tests/classes}"
thread-count="{number of thread}".
<suite name="ArtOfTestingTestSuite" parallel="methods" thread-count="5">
</code>


<b>Ques. What is the use of @Listener annotation?</b>
Ans. TestNG provides us different kinds of listeners using which we can perform some action in case an event gets triggered. We can use these listeners for various purposes like - taking screenshots in case of failure, logging, etc.
<code>
@Listeners(PackageName.CustomizedListenerClassName.class)
 
public class TestClass { 
    WebDriver driver= new FirefoxDriver();@Test
    public void testMethod(){
    //test logic
    }
} 
</code>


<b>Ques. What is the use of @Factory annotation?</b>
Ans. The @Factory annotation helps in the dynamic execution of the testNG tests. Using @Factory annotation, we can pass parameters to the whole test class at run time.
<code>public class TestClass{
    private String str;
    public TestClass(String str) {
        this.str = str;
    }
  
    @Test
    public void TestMethod() {
        System.out.println(str);
    }
}
  
public class TestFactory{
    //The test methods in class TestClass will run twice with data "k1" and "k2"
    @Factory
    public Object[] factoryMethod() {
        return new Object[] { new TestClass("K1"), new TestClass("k2") };
    }
}</code>

Project ideas: How to come up with one.
Tags: projectideas
Published: 2020-09-25 11:54:41

![dollar-gill-R1lBOCUNHRU-unsplash](https://dev-to-uploads.s3.amazonaws.com/i/6qfpah4cjzvvnokjwumn.jpg)
Have you ever wanted to do projects but can't seem to get past the first step, which is coming up with a project idea? It can be quite daunting trying to come with a project idea and even more so when you plan on entering the project into major competitions like the Microsofts Imagine Cup competition. So in light of that, I will be giving some ways in which you can come up with one;


**Inspiration from existing problems**
The secret to a good project is one that aims at and has the prospects of solving an already existing problem. Therefore, a sure way to come up with an idea would be to draw inspiration from the challenges you see around you and try to solve them.

**Exploring Github**
Github has an extensive pool of projects worked on by different people and it, therefore, serves as a source of ideas either from the trending repositories and deciding to work on that or even identifying areas of improvement in an existing project. Improving the existing project could mean either taking a single feature from it and adding significant functionality to make it a project on its own or identifying a flaw in the existing project and improving on it significantly.


**Brainstorming with colleagues**
Forums such as hackathons or engaging your colleagues can serve to give insight on the potential project you could take up. A hackathon is even more beneficial because in addition to the opportunity to engage other people with the same interest it provides an opportunity to carry out projects to the end.

**Searching the Internet**
This could be the most obvious one yet but my list would not be complete without it. The internet is full of project ideas in different fields, some explored others not. It can be overwhelming so the trick is to choose one which you will most likely enjoy and also can potentially solve some common problems.![kyle-glenn](https://dev-to-uploads.s3.amazonaws.com/i/o9hqcuaanxa0x8u69bdm.jpg)
