1,896,015 | Securing your machine identities means better secrets management | In 2024, GitGuardian Released the State of Secrets Sprawl report. The findings speak for themselves;... | 0 | 2024-06-21T13:13:54 | https://blog.gitguardian.com/securing-your-machine-identities/ | security, devops, cybersecurity, identity | In 2024, GitGuardian Released the [State of Secrets Sprawl ](https://www.gitguardian.com/state-of-secrets-sprawl-report-2024?ref=blog.gitguardian.com)report. The findings speak for themselves; with over 12.7 million secrets detected in GitHub public repos, it is clear that hard-coded plaintext credentials are a serious problem. Worse yet, it is a growing problem, year over year, with 10 million found the previous year and 6 million found the year before that. These are not cumulative findings!
[Download the 2024 State of Secrets Sprawl Report](https://www.gitguardian.com/state-of-secrets-sprawl-report-2024)
When we dig a little deeper into these numbers, one overwhelming fact springs out: specific secrets detected, the vast majority of which are API keys, outnumber generic secrets detected in our findings by a significant margin. This makes sense when you realize that API keys are used to authenticate specific services, devices, and workloads within our applications and pipelines to enable machine-to-machine communication. This is very much in line with research from CyberArk, [machine identities outnumber human identities by a factor of 45 to one](https://www.cyberark.com/resources/blog/why-machine-identities-are-essential-strands-in-your-zero-trust-strategy?ref=blog.gitguardian.com#:~:text=Machine%20Identities%20Now%20Outnumber%20Human%20Identities%20by%20a%20Factor%20of%2045%20to%20One). This gap is only going to widen continually as we integrate more and more services in our codebases and with ever-increasing velocity.

*Specific vs Generic secrets in the State of Secrets Sprawl Report 2024 findings*
Secrets sprawl is clearly a problem for both human and machine identities, so why should we call out this distinction?
Machine identities
------------------
GitGuardian will be leaning into the term "machine identities" moving forward as a way to distinguish this area of secrets sprawl and its unique challenges apart from human identities and credentials. Each is problematic, but each calls for different approaches. We are following the naming convention from industry leaders in secrets management, such as CyberArk and analyst firms who define the industry, such as Gartner, in standardizing this terminology. Gartner defines the term in their [2020 IAM Technologies Hype Cycle ](https://www.appviewx.com/blogs/gartner-adds-machine-identity-management-to-its-hype-cycle-for-iam-technologies-2020/?ref=blog.gitguardian.com)report as, "Simply put, a machine identity is a credential used by any endpoint (which could be an IoT device, a server, a container, or even a laptop) to establish its legitimacy on a network." This term covers all API access keys, certificates, Public key infrastructure (PKI), and any other way possible to authenticate machine-to-machine communication.
### Is a machine identity the same as a non-human Identity?
From a purely grammatical perspective, it must be a non-human identity if it is not a human identity. So why use the specific term machine identity? Well, practically speaking, a non-human could be a dog, a plant, or even a planet. When using the term "non-human" we must also necessarily further qualify what we mean, while the term 'machine identity' already has a widely accepted definition that narrows the scope to the secrets sprawl problem space.
For example, [Venafi, a leading machine identity management platform, ](https://venafi.com/machine-identity-basics/what-is-machine-identity-management/?ref=blog.gitguardian.com#item-4)succinctly states, "The phrase "machine" often evokes images of a physical server or a tangible, robot-like device, but in the world of machine identity management, a machine can be anything that requires an identity to connect or communicate---from a physical device to a piece of code or even an API."
How did we get here?
--------------------
Before we can talk about what to do about the issues of machine identities and secrets sprawl, it might be helpful to take a historical look at how we arrived at this point in the industry. In the early days of computer science, the only 'entities' we had to worry about accessing our machines and our code were humans. In the days of [ENIAC](https://www.computerhistory.org/revolution/birth-of-the-computer/4/78?ref=blog.gitguardian.com#:~:text=The%20result%20was%20ENIAC%20(Electronic,slowed%20by%20any%20mechanical%20parts.) or [early UNIX systems](https://www.hpc.iastate.edu/guides/unix-introduction?ref=blog.gitguardian.com), using a simple password and perhaps sturdy locks on the doors were really all you needed to ensure only the proper people could access a system. People love passwords, and we have for thousands of years. The Roman garrison used 'watchwords', which needed to be updated nightly, meaning we have been practicing manual password rotation for a couple of millennia now.
So, naturally, when it came time to implement machine-to-machine authentication, ensuring that we were only allowing access to trusted systems to recognize and communicate with one another, it was only natural we would turn to our old friend the password, in the form of a long and hard to guess token to get the job done. This system works okay until you remember the problem statement that started this article: we keep leaking these credentials into our code and into places around our code like Jira, Slack, and Confluence at an alarming rate.
Solving both human identity and machine identity sprawl
-------------------------------------------------------
Now that we have a common vocabulary and understand the two areas of concern, human and machine, what are our next steps? Let's start with human identities. People need to be able to authenticate to gain access to systems to get their work done. Using phishing-resistant MFA, preferably hardware-based, at every juncture where a human uses a password is a solid approach. Even if a password is leaked, it is much harder to exploit and gives the user time to rotate the credential. While not a silver bullet, [Microsoft believes this could stop up to 99.9% of fraudulent sign-ins](https://www.microsoft.com/en-us/security/blog/2019/08/20/one-simple-action-you-can-take-to-prevent-99-9-percent-of-account-attacks/?ref=blog.gitguardian.com). Even better, if there is a way to eliminate that password, such as with a passkey using FIDO2 or hardware-based biometrics for authentication, then we should probably move in that direction.
Dealing with machine resources requires a different approach, as we can't just turn on MFA for machines. We also can't disrupt these machine identities, as the business of the enterprise is to do business, and the connections must continue to allow our systems to function and satisfy the availability leg of the [CIA Triad](https://www.nccoe.nist.gov/publication/1800-26/VolA/index.html?ref=blog.gitguardian.com). Similarly, we can not devote endless resources and hours to this issue, as new vulnerabilities in the form of CVEs, misconfigurations and licensing issues continue to be other areas security teams need to tackle.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXdL2aWek4nU9viRBhBQuDplVwC1CXBOaP1okL1Oo0CjSkac0jDtScZObrWwcFIkyBhMpgl_3pyCCHMDiiEMH2zX0sE653GcAZ5ZaxzE1Zb1iqZMGvLcik7OwMip3yJZBNu2cxkRIwQBrOi025XcB-r5jKM?key=YiW08aLCImqgtwGFet5dRQ)
*CIA triad*
In an ideal world, we could immediately move all of our systems to leverage short-lived certificates or JWTs that are issued at run time when needed and only live for the life of the request. Indeed, there are [frameworks such as SPIFFE and its implementation, SPIRE](https://spiffe.io/?ref=blog.gitguardian.com), that can help organizations achieve this goal. While this is indeed a great approach, it has the real-world issues of developer adoption, development time and effort, and the overhead of running such services at scale.
While we can dream up many such ideal scenarios, we need to address the current situation head-on. Developers will continue to use machine identities, which can be leaked and exploited by attackers. At the same time, we know that if a malicious actor gets their hands on a secret, they can only leverage it if it is still valid. We believe the best practical solution for any organization is to rotate secrets much more frequently.
Automatically rotating secrets more frequently
----------------------------------------------
One of the other stand-out findings from our State of Secrets Sprawl Report was the fact that of all the valid secrets we discovered in public, over [90% were still valid five days later](https://www.gitguardian.com/state-of-secrets-sprawl-report-2024?ref=blog.gitguardian.com#:~:text=More%20than%2090%25%20of%20the%20secrets%20remain%20valid%205%20days%20after%20being%20leaked). We believe this points to the fact that teams expect secrets to be long-lived and that the current manual approach to secrets rotation is hard. Further evidence of these conclusions can be found in breach reports involving companies such as [Cloudflare](https://blog.gitguardian.com/the-secrets-out-how-stolen-auth-tokens-led-to-cloudflare-breach/).
In our [Secret Management Maturity Model](https://blog.gitguardian.com/a-maturity-model-for-secrets-management/) white paper, a clear differentiator in organizations in the Advanced and Expert categories is that they have adopted regular credential rotation policies. It is very unlikely these mature organizations are doing manual rotation, as that would be an overwhelming, time-consuming, and error-prone process, which potentially could mean disaster in our interconnected architectures.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXcpStK5msXj9OcoPonNsa85Cby5enrT3ppoqMFhajBd8eB6wO8yh5uTp4fSZoSPTvwrr3bWualVkm0T7lOiY4QGj5K1Irqdd7ClJxpoejEYsO-AWsTRpZNW-I55f2Dp6Z2gTndsOs9ebPgB3A4ka-qyd4s?key=YiW08aLCImqgtwGFet5dRQ)
*Experts level of the Secrets Management Maturity Model*
We need a way to automate the rotation process. The good news is that awesome tools are available, such as [CyberArk's Conjure](https://www.conjur.org/?ref=blog.gitguardian.com) or [AWS Secrets Manager](https://docs.aws.amazon.com/secretsmanager/latest/userguide/rotating-secrets.html?ref=blog.gitguardian.com), that make the process of auto-rotation pretty straightforward. Of course, this assumes all of your machine identities already and totally live within their system.
### Auto-rotation of secrets first means knowing all your machine identities
Now, we could ask for every developer and infrastructure owner to give security teams a list of all their credentials in plaintext for all their various workloads, services, and devices, but obviously, that is a terrible and highly problematic idea.
In all seriousness, what is needed is a scalable end-to-end solution that can help you systematically and automatically find all the plaintext credentials inside of your code base, leaked out onto GitHub publicly, or even found in the communication tools that surround your code. Good news! GitGuardian makes exactly this. This is the heart and soul of our [Secrets Detection Platform](https://www.gitguardian.com/monitor-internal-repositories-for-secrets?ref=blog.gitguardian.com).
Automating the discovery and auto-rotation of machine identities with Brimstone
-------------------------------------------------------------------------------
GitGuardian has partnered with CyberArk to offer a unique solution for security teams to detect machine identity leaks and manage their remediation effectively. [We call this project Brimstone](https://blog.gitguardian.com/cyberark-integration-tutorial/). This innovative integration allows communication between the GitGuardian Secrets Detection platform and CyberArk's Conjur, automatically addressing leaked machine identities across various critical scenarios.
- "Unknown" machine identities. Known machine identities already exist in Conjur and need rotation or revocation, while unknown machine identities should be created there and then auto-rotated.
- Known machine identities found in sources monitored by GitGuardian.
- Publicly exposed machine identities on GitHub.com.
If you are already a CyberArk Conjur user, [reach out to us to schedule a time](https://www.gitguardian.com/book-a-demo?ref=blog.gitguardian.com) to discuss how you can take advantage of this integration.

1,896,012 | What is C# Compiler ? How to Use it Full Guide | Mastering the C# Compiler: Your Complete Guide to Understanding and Implementation In the... | 0 | 2024-06-21T13:12:46 | https://dev.to/scholarhat/what-is-c-compiler-how-to-use-it-full-guide-1i17 | ## Mastering the C# Compiler: Your Complete Guide to Understanding and Implementation
In the realm of modern software development, C# stands out as a powerful and versatile programming language. At the heart of C#'s functionality lies its compiler, a crucial tool that transforms human-readable code into machine-executable instructions. This comprehensive guide will delve into the intricacies of the C# compiler, exploring its role, functionality, and how to harness its power effectively.
Before we dive deeper, it's worth noting that if you're looking to experiment with C# code quickly, you can use a [c# online compiler](https://www.scholarhat.com/compiler/csharp) to test your code without setting up a local development environment. Additionally, for those preparing for technical interviews, brushing up on [c# interview questions and answers](https://www.scholarhat.com/tutorial/csharp/csharp-interview-question-answers) can be incredibly beneficial.
Understanding the C# Compiler
## What is a C# Compiler?
A C# compiler is a specialized software tool designed to translate C# source code into an intermediate language (IL) that can be executed by the .NET runtime environment. This process is fundamental to the execution of C# programs, as it bridges the gap between human-readable code and machine-executable instructions.
## The Role of the C# Compiler in Software Development
The C# compiler plays several critical roles in the software development process:
Code translation
Syntax checking
Type checking
Code optimization
Generation of metadata
By performing these tasks, the C# compiler ensures that your code is not only executable but also optimized for performance and free from basic errors.
## How the C# Compiler Works
## The Compilation Process
The C# compilation process involves several stages:
Lexical Analysis
Syntax Analysis
Semantic Analysis
Intermediate Language (IL) Generation
Metadata Generation
Each of these stages contributes to the transformation of your C# source code into a form that can be efficiently executed by the .NET runtime.
## Just-In-Time (JIT) Compilation
While the C# compiler translates source code to IL, the actual machine code is generated at runtime through a process called Just-In-Time (JIT) compilation. This approach allows for platform-independent code that can be optimized for the specific hardware it's running on.
## Types of C# Compilers
## Microsoft's C# Compiler
The most widely used C# compiler is Microsoft's official compiler, which is part of the .NET SDK. This compiler, often referred to as Roslyn, is open-source and highly extensible.
## Alternative C# Compilers
While Microsoft's compiler is the standard, there are alternative C# compilers available:
Mono C# Compiler
DotGNU Portable.NET
SharpDevelop
These alternatives can offer different features or optimizations, though they may not always support the latest C# language features.
## Benefits of Using the C# Compiler
Code Verification and Error Detection
One of the primary advantages of using the C# compiler is its ability to catch errors early in the development process. The compiler performs:
Syntax checking
Type checking
Semantic analysis
These checks help developers identify and fix issues before the code is executed, leading to more robust and reliable applications.
## Performance Optimization
The C# compiler includes various optimization techniques to enhance the performance of your code:
Dead code elimination
Constant folding
Loop unrolling
Inlining of small methods
These optimizations can significantly improve the execution speed and efficiency of your C# applications.
## How to Use the C# Compiler
## Setting Up Your Development Environment
To start using the C# compiler, you'll need to set up your development environment:
Install the .NET SDK
Choose an Integrated Development Environment (IDE) like Visual Studio or Visual Studio Code
Configure your project settings and references
Once your environment is set up, you're ready to start compiling C# code.
## Command-Line Compilation
While IDEs often handle compilation automatically, you can also compile C# code from the command line:
Open a command prompt or terminal
Navigate to your project directory
Use the csc command to compile your C# files
For example:
Copy
csc MyProgram.cs
This will generate an executable file from your C# source code.
## Advanced Compiler Features
## Compiler Directives
C# compiler directives allow you to control the compilation process:
#define and #undef for defining and undefining symbols
#if, #elif, #else, and #endif for conditional compilation
#warning and #error for generating compiler warnings or errors
These directives give you fine-grained control over how your code is compiled.
## Unsafe Code and Compiler Options
The C# compiler allows for unsafe code, which can be useful for low-level operations:
Use the unsafe keyword to define unsafe contexts
Enable unsafe code compilation with the /unsafe compiler option
Be cautious when using unsafe code, as it bypasses C#'s type safety and memory management features.
## Best Practices for Working with the C# Compiler
## Writing Compiler-Friendly Code

1,896,006 | Why ['1', '5', '11'].map(parseInt) in JS returns [1, NaN, 3]? | In JavaScript, the map function applies a given function to each element of an array and returns a... | 0 | 2024-06-21T13:03:09 | https://dev.to/vcpablo/why-1-5-11mapparseint-in-js-returns-1-nan-3-28ef | javascript, webdev, programming | In JavaScript, the map function applies a given function to each element of an array and returns a new array with the results. When you use map with parseInt like ['1', '5', '11'].map(parseInt), the result might not be what you expect due to the way parseInt and map interact. Let's break down what happens.
### Understanding parseInt
The parseInt function in JavaScript parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems).
```js
parseInt(string, radix)
```
- `string`: The string to be parsed.
- `radix`: An integer between 2 and 36 that represents the radix (the base in mathematical numeral systems) of the string.
If radix is not provided, parseInt will use different heuristics to determine the base of the string, which can lead to unexpected results.
### The map Function
The map function calls the provided function once for each element in an array, in order, and constructs a new array from the results.
```javascript
array.map(function(currentValue, index, array) {
// function body
})
```
- `currentValue`: The current element being processed in the array.
- `index`: The index of the current element being processed in the array.
- `array`: The array map was called upon.
### Combining map and parseInt
When you use parseInt inside map, parseInt is called with two arguments: the element of the array and the index of that element. However, parseInt can take two arguments where the second argument is the radix. So, the index is inadvertently used as the radix.
Here's how it breaks down:
For the first element '1' at index 0:
```javascript
parseInt('1', 0) // 0 is interpreted as the radix, which defaults to 10
// Result: 1
```
For the second element '5' at index 1:
```javascript
parseInt('5', 1) // 1 is interpreted as the radix, but radix 1 is invalid
// Result: NaN (Not a Number)
```
For the third element '11' at index 2:
```javascript
parseInt('11', 2) // 2 is interpreted as the radix (binary)
// '11' in binary is 3 in decimal
// Result: 3
```
Thus, `['1', '5', '11'].map(parseInt)` results in `[1, NaN, 3]`.
### Correct Usage
To avoid this issue, you can pass a function that only uses the first argument of parseInt and defaults the radix to 10:
```javascript
['1', '5', '11'].map(str => parseInt(str, 10)) // [1, 5, 11]
```
or just ommit the `radix` param:
```javascript
['1', '5', '11'].map(str => parseInt(str)) // [1, 5, 11]
```
Here, str is explicitly converted to an integer using a base of 10 for each element in the array, resulting in [1, 5, 11].

* I wanted declarative markup
* I wanted type-safe component encapsulation, with composition & inheritance
* I wanted a small, fast, client-side solution with no complex build process (or any build process!)
...but most importantly...
* I didn't want to learn a whole new API just to manipulate data _I already have in my app_
In my single page apps, I've got remote APIs and endpoints that supply data. Sure, I might want to do a bit of arithmetic, sorting, formatting, but basically, I want to say to the UI: "Here's my data, render it into the DOM". When the data changes, either because the server tells me or the user manipulates it locally, I don't want to re-render anything - I've already laid out my page - I just want the DOM to automagically re-render.
How can I do this using the most familiar JS syntax possible? **Iterable Properties**
## Show me!
Let's start with one of the basic examples in the AI-UI repo: a [clock](https://raw.githack.com/MatAtBread/AI-UI/main/guide/examples/readme.html).
We're not really interested in the clock itself, we're going to use Chrome Dev tools create iterable properties on a basic JS object, and see how they work. Go to the example, and open Dev Tools with `Ctrl (Cmd) + Shift + I`
We're using this script (as opposed to the ECMA module) as it defines the global constant `AIUI`, so we can just play.
A key sub-module of `AIUI` is the [`Iterators`](https://github.com/MatAtBread/AI-UI/blob/main/guide/iterators.md) interface. Let's grab a reference to it for later use, and just create a plain old JS object.
In the Dev Tools console, type:
```javascript
defineIterableProperty = AIUI.Iterators.defineIterableProperty;
xxx = { foo: 123 };
```
So `xxx` is just an object. Nothing special here. Let's add an iterable property to it. The syntax is `defineIterableProperty(object, key, initialValue)`:
```javascript
defineIterableProperty(xxx,"bar",456);
// xxx.bar just looks like a normal property:
xxx.bar * 10
// 4560
xxx.bar -= 111;
// 345
```
But `xxx.bar` has some magic: it's also an async iterator:
```javascript
for await(const v of xxx.bar) console.log("bar is now",v)
// bar is now 345
xxx.bar = 100
// bar is now 100
//100
xxx.bar++
// bar is now 101
// 100
xxx.bar = "Wow!"
// bar is now Wow!
//'Wow!'
```
If you prefer a more functional style, AI-UI comes with a handy bunch of helpers like [`map`, `filter` and `consume`](https://github.com/MatAtBread/AI-UI/blob/main/guide/iterators.md#helper-functions)
```javascript
xxx.bar.map(v => v * 10).consume(v => console.log("Or 10x more is",v));
// Promise {<pending>}
xxx.bar = 99;
// bar is now 99 <--- for...await is still going!
// Or 10x more is 990 <--- same value mapped
// 99
```
## Is that it?
Yep. That's it. No 'setState()', no hooks, signals, or other API to learn. You just define an iterable property, read and write to it like normal, and consume the results as it changes.
It's this simplicity that makes AI-UI one of the simplest UI modules to use. Just layout your markup specifying iterable values in your variable substitutions like `<div>${xxx.bar}</div>`, and it just works by consuming your iterable values and updating the DOM.
Of course, defining all your own properties by hand is a bit repetitive, so AI-UI components can create a bunch for you using the [`iterable` member](https://github.com/MatAtBread/AI-UI/blob/main/guide/prototype.md#iterable), but that's not the core functionality.
The `Iterators` submodule is pure-JS, with no DOM dependencies, so you can use it in NodeJS apps with
```javascript
import '@matatbread/ai-ui/esm/iterators.js';
```

Based on Microsoft (*father of C-Sharp*), it is modifier to **declare a static member**, which **belongs to the type itself** rather than to a specific object. For example, class have structure following:
```csharp
class Test(){
public string Content;
}
```
In `main` function, we have:
```csharp
static void Main(string[] args){
var t1 = new Test() { Content = "Test 1" };
var t2 = new Test() { Content = "Test 2" };
Console.WriteLine(t1.Content); //output: Test 1
Console.WriteLine(t2.Content); // output: Test 2
}
```
So we can see the output will difference with other instance. But if we use `static` in class, what happen?
```csharp
class Test(){
public static string Content;
}
```
And update in `main` function:
```csharp
static void Main(string[] args){
var t = new Test() { };
//error here because you can't access static property through by instance
Console.WriteLine(t.Content);
Test.Content = 'Static Content'
Console.WriteLine(Test.Content); //output: Static Content
ChangeContent("Update content with function");
Console.WriteLine(Test.Content); //output: Update content with function
}
static void ChangeContent(string content)
{
Test.Content = content;
}
```
Compare `main` before and after, we have table conclusion:
| | Non static | Static |
| --------- | ----------------------------- | ----------------- |
| Create at | New instance create | Compiler time |
| Access by | Instance | Class |
| Value | Follow the instance | Follow the class |
| Life time | Until the instance deallocate | Until program end |
**P/s:** With `static` keyword, the variable will be stored in heap memory, below is short description about **stack & heap**:
| | Stack | Heap |
| ------------------ | ------------------------------------------------------------- | ------------------------- |
| Store | - Primitive type <br>- Reference variable<br>- Function call | - Object<br>- Static type |
| Structure | Last In First Out (LIFO) | Dynamic |
| Performance access | Faster | Slower |

1,895,996 | A Full Guide to Making Sure Stable Releases to Production with UI Automation Testing | Introduction: When it comes to making software, the path from code to production is not always easy.... | 0 | 2024-06-21T12:50:25 | https://dev.to/coderowersoftware/a-full-guide-to-making-sure-stable-releases-to-production-with-ui-automation-testing-281e | webdev, testing, development, softwaredevelopment | **Introduction:**
When it comes to making software, the path from code to production is not always easy. Making sure that updates to production settings are stable is one of the most important parts of this trip. **Releases that aren’t stable can cause problems, cost money, and hurt a company’s image**. To lower these risks, developers use different testing methods. UI automation testing is becoming an important part of the quest for stable updates. We go into great detail about UI automation testing in this blog post, which also talks about how it helps make sure that safe releases go to production.
**Understanding Why Stable Releases Are Important**
When it comes to software creation, where things move quickly and customers have high standards, stable releases are very important. Releases that are stable don’t have any major bugs, mistakes, or other problems that could stop the software from working in business settings. When updates are risky, it can cause a chain reaction of issues, such as
**- Downtime**: Releases that aren’t stable can cause system crashes that make the software unavailable to users. Businesses, especially those that make a lot of money from their digital sites, may have to pay a lot for this downtime.
**- Income Loss**: Unstable versions can cause downtime and other problems that can directly affect income lines. Customers could leave the site for a rival, which would mean lost sales and money.
**- Damage to Reputation**: Having a bad name for making software that doesn’t work can hurt a company’s brand image. People are less likely to trust and keep using software that fails and has problems often.
Software development teams must make sure that their versions are stable if they want to keep customers’ trust, happiness, and loyalty.
**How UI Automation Testing Has Changed Over Time?**
Over the years, testing methods have come a long way because of the need for safe versions. Traditional manual testing works in some situations, but it’s not good for current development methods because it has built-in flaws. Manual testing takes a lot of time, effort, and mistakes are common. It became clear that software projects needed to be automated as they got more complicated and release cycles got shorter.
UI automation testing, which is also called GUI testing or front-end testing, simulates how a user would interact with an app’s graphical user interface (GUI). For this technology to work, special tools and frameworks are used to mimic human movements like pressing buttons, typing, and moving between screens. The following steps show how UI automation testing has changed over time:
**Code Example:**
```
# Example Python code snippet for UI automation testing using Selenium
from selenium import webdriver
# Set up the Selenium WebDriver
driver = webdriver.Chrome()
# Open the website to be tested
driver.get(“https://example.com")
# Perform UI actions
element = driver.find_element_by_id(“some_id”)
element.click()
# Verify UI elements and functionalities
assert “Expected Result” in driver.title
# Close the browser
driver.quit()
```
**- Manual Testing**: Testing software was mostly done by hand in the early days of the field. Testers would run test cases by hand, look at the results, and report any problems or flaws they found. Manual testing gave some basic peace of mind, but it wasn’t very useful for big projects with lots of releases.
**- Scripted Testing**: When testing tools came out, testers could write scripts to automated test cases that were done over and over again. It would take less time and effort to test with these tools because they would simulate user activities and check that expected results happened. Despite this, automated testing still needed human help to run and analyze the results.
**- Framework-based Testing**: Thanks to automatic testing tools like Selenium, Appium, and Cypress, testing has become easier to use and can be scaled up. These systems gave you libraries and tools to automate different parts of testing, like making API calls, checking the user interface, and working with databases. Framework-based testing let teams run tests on a variety of devices and browsers, which increased the number of tests that were run and made them more reliable.
**- Continuous Testing**: When continuous integration and continuous release (CI/CD) came along, testing became an important part of the development process. Running automatic tests early and often during the development process is called continuous testing. This makes sure that any problems are found and fixed quickly. This shift-left way of testing helps teams find bugs earlier in the development process, which lowers the risk of putting risky code into production.
The development of UI automation testing has changed the way software is tried and proven. This has led to faster release processes, better quality standards, and more trust in deployments to production.
**Why UI Automation Testing Is Good?**
UI automation testing has many benefits for software development teams, such as making them more productive and improving the quality of their work. Some of the best things about UI automatic tests are the following:
**Code Example:**
```
// Example of UI automation testing with Selenium WebDriver in Java
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class ExampleTest {
public static void main(String[] args) {
WebDriver driver = new ChromeDriver();
driver.get(“https://example.com");
WebElement element = driver.findElement(By.id(“username”));
element.sendKeys(“user@example.com”);
element.submit();
driver.quit();
}
}
```
**- Better Test Coverage**: Compared to human testing, automated tests can cover a wider range of situations, ensuring the software’s usefulness is fully confirmed. Teams can focus their human testing on complex edge cases and scenarios that are hard to automate by scripting test cases that are done over and over again.
**- Faster Time-to-Market**: Automation cuts down on the time needed to run tests, so you can get feedback on changes to the code more quickly. When test rounds are shorter, development teams can make changes more quickly and get new features into production more quickly. In today’s market, where speed is often the key to success, this flexibility is very important.
**- Less Work to Do by Hand**: Automating tasks that are done over and over again frees up time and resources that can be used for more important tasks. Instead of spending hours running tests by hand, testers can focus on making strong test cases, studying test results, and finding places where things could be better.
**- Consistency and Reliability**: When automated tests are run, they always do the same steps. This gets rid of the variability that comes with human testing. This stability makes sure that tests give true results, so teams can believe that the results of their tests are correct.
**- Regression Testing**: UI automation testing works really well for regression testing, which checks changes to the script to make sure they don’t cause new bugs or regressions. Automated regression tests can be run quickly and often, telling you right away how changes to the code affect things.
**- Scalability**: Frameworks for automated testing are made to grow with the size and complexity of software projects. Automation tools can handle a lot of work, so the results are always the same and accurate, whether they are checking a small web app or a big business system.
UI automation testing has many benefits that can help development teams speed up their testing, get more done, and confidently release high-quality software to the market.
**Adding UI Automation Testing to the SDLC**
UI automation testing needs to be carefully planned, coordinated, and carried out in order to be successfully added to the software development process (SDLC). To make UI automation testing work well, here are some best practices:
**Code Example:**
```
# Example of CI/CD pipeline configuration for UI automation testing with Selenium WebDriver
# .gitlab-ci.yml
stages:
- test
test:
stage: test
script:
- python test_script.py
```
**- Set Clear Goals for Testing**: Before you start robotic testing, make sure you have clear goals and targets for your testing. Choose which types of tests to automate, like functional tests, failure tests, and smoke tests, based on how often and how important the features being tested are.
**- Choose the Right Tools and Frameworks**: Pick automation testing tools and frameworks that fit the needs of your project, your team’s skills, and the technologies you’re using. Automation tools like Selenium, Appium, and Cypress are very popular and can be used to test web, mobile, and PC apps in many different ways.
**- Make Strong Test Cases**: Use best practices like the Page Object Model (POM) or Screenplay Pattern to make test cases that are flexible, repeatable, and easy to manage. Make your test scripts easy to read and keep up to date by giving each test case a name and adding notes that explain what it does.
**- Connect to CI/CD Pipelines**: Add automatic tests to your CI/CD pipelines to make testing happen all the time during the development process. Running automated tests as soon as new code is added to the folder will make sure that any bugs are found and fixed early in the development process.
**- Collaborate Between Teams**: Encourage coders, testers, and other partners to work together to make sure that everyone agrees on the testing goals, coverage, and standards for release. To deal with problems and make things better, encourage open conversation and feedback loops.
**- Monitor Test Results and Performance**: Set up metrics, like test run time, test coverage, flaw detection rate, and false positive rate, to see how well your automation testing is working. Regularly look at test scores and performance to find patterns, trends, and places to improve. You can see important data and keep track of your work over time with test automation platforms and reporting tools.
**- Set Priorities for Test Cases**: Set priorities for test cases based on how important they are, how they affect the user experience, and how often they are used. Focus your automation efforts on the most important test cases that cover key features and important processes. Risk-based testing methods could help you make better use of your testing tools and lower the risks that come with them.
**- Maintain Stability in the Test Environment**: To cut down on test fails and fake positives, make sure that your test environment is stable and consistent. Manage test scripts and test data with version control systems. This will make sure that tests are run in a controlled setting that can be repeated. Work with system managers and DevOps teams to make sure that test settings are as close as possible to production.
**- Implement Test Data Management Strategies**: Come up with strong ways to handle test data in settings where automatic testing is used. To make sure you’re following the rules for data safety and security, use fake or anonymous test data. To keep private data safe in test settings, think about using data hiding or obfuscation. To speed up testing and cut down on manual work, automate the creation and supply of test data.
**- Always Make Testing Processes Better**: Encourage a mindset of always getting better by asking team members, partners, and end users for feedback. Do regular retrospectives to think about the testing you’ve done in the past, find ways to make it better, and take corrective steps. To find secret bugs and improve the user experience, test methods like experimental testing, usability testing, and performance testing should be open to new ideas and experiments.
By following these guidelines and best practices, development teams can successfully add UI automation testing to the SDLC and get the most out of automation to make sure stable releases to production settings.
**How to Get Around Problems in UI Automation Testing**
There are many good things about UI automation testing, but there are also some problems that need to be fixed before it can be widely used. These are some of the most usual problems that come up in UI automation testing:
**Code Example:**
```
// Example of UI automation testing with Cypress in JavaScript
describe(‘Example Test’, () => {
it(‘Visits the website’, () => {
cy.visit(‘https://example.com')
cy.get(‘#username’).type(‘user@example.com’).type(‘{enter}’)
})
})
```
**- Check for Maintenance**: Maintaining automatic test scripts can be hard, especially in software systems that change quickly and are always changing. When the application’s user interface, feature, or base technology stack changes, test tools may need to be updated too. This adds to the work that needs to be done for upkeep. To get around this problem, use a modular testing method, in which test files are broken up into parts that can be used again and again and are easy to manage and update. To keep UI interactions separate and make changes to test scripts less noticeable, use design patterns like the Page Object Model (POM) or Screenplay Pattern.
**- Test Flakiness**: Test results are inconsistent or hard to predict. Tests may pass or fail at random because of things in the surroundings, time problems, or race conditions. Testing that doesn’t work properly can make people less confident in automated testing and make test automation less useful. To fix flaky tests, you should look into why they are flaky and use methods to make tests more reliable. This could mean adding wait conditions, retries, or timeouts to deal with actions that happen at different times, making sure that test running happens at the same time as changes to the application state, or using methods like dynamic locators to make sure that tests work the same way in all settings and setups.
**- Platform Compatibility**: Testing apps on a lot of different devices, platforms, and websites makes automatic testing more difficult and complicated. Platform features, screen sizes, entry methods, and browser habits can all change, which can affect how tests are run and lead to different test results. Make sure your platform works with all of the sites and gadgets that people in your target market use by planning a thorough cross-browser testing approach. With cloud-based testing tools, you can access many virtualized test settings and set up cross-browser testing to run automatically across many browsers. Tools and systems that allow cross-browser testing by default, like Sauce Labs, Selenium Grid, or BrowserStack, should be thought about.
**- Test Data Management:** It can be hard to keep track of test data in settings where automation testing is used, especially when there are a lot of files, private data, or a lot of data relationships. Test data management includes chores like creating data, providing it, hiding it, synchronizing it, and cleaning it up. All of these are necessary to make sure that automatic tests are accurate and can be run again and again. Automate the creation and distribution of test data, reduce data duplication and error, safeguard private data, and make sure that data privacy and security rules are followed when managing test data. Separate test logic from test data using data-driven testing, modelling, and data-driven test automation tools. This will make it easier to reuse and maintain test scripts.
**- Test Environment Setup and Configuration**: It can take a long time and be hard to get things right when setting up and creating test environments for automated testing, especially in complex distributed systems or cloud-based designs. When test settings aren’t set up correctly or consistently, tests can fail, false positives can happen, and test results can be wrong. This makes automation testing less useful. By using explicit setup files or scripts, you can handle the setting up and provisioning of test environments with infrastructure as code (IaC). Use containerization tools like Docker or Kubernetes to separate test environments and their dependencies. This will make sure that the code is consistent and can be run again in different settings and environments. Use infrastructure automation tools like Terraform, Ansible, or Chef to set up and configure test infrastructure automatically. This includes servers, databases, networking, and software.
By being aware of these problems ahead of time and using the best methods and techniques to solve them, development teams can make UI automation testing more effective and efficient and make sure that safe releases go to production environments.
**How to Tell If UI Automation Testing Worked**
Setting clear measurements and Key Performance Indicators (KPIs) to measure the usefulness, speed, and impact of automation testing efforts is necessary to figure out how successful UI automation testing is. Some of the most important ways to measure how well UI automation testing is working are:
**Code Example:**
```
// Example of UI automation testing with Cypress in JavaScript
describe(‘Example Test’, () => {
it(‘Visits the website’, () => {
cy.visit(‘https://example.com')
cy.get(‘#username’).type(‘user@example.com’).type(‘{enter}’)
})
})
```
**- Test Coverage**: The amount of program code or functionality that is covered by automatic tests is called test coverage. A test suite that covers a lot of ground and checks most of an application’s features and cases is said to have high test coverage. To reduce the chances of bugs and other problems, make sure that a lot of tests are run on all of the important and dangerous parts of the application.
**- Defect Detection Rate:** The defect detection rate tells you how many bugs or other problems were found by automatic tests during the testing process. A high defect discovery rate means that the test automation is working well and finding and reporting defects early in the development process. This lowers the cost and effort needed to fix flaws.
**- Test Execution Time**: This is the amount of time it takes to run automatic tests from beginning to end. Shorter test run times make it possible to get feedback on changes to code more quickly, which speeds up iterations and releases. Regularly check the times it takes to run tests and make sure that test scripts, test settings, and test systems are working at their best to reduce the time it takes to run tests.
**- Test Automation ROI**: The return on investment (ROI) for test automation shows how much money or time is saved by using automation testing instead of human testing. Figure out the return on investment (ROI) by looking at things like less testing work, better test coverage, faster time to market, and lower costs for fixing bugs. Do regular ROI analyses to show that the money you spend on automation testing is worth it and to find ways to make things even better and more efficient.
**- False Positive Rate**: The false positive rate shows what number of failed automatic tests are not really bugs or problems with the program. High rates of false positives mean that the tests aren’t reliable and give uneven or wrong results. To make tests more reliable and cut down on false positives, keep an eye on the number of false positives and look into why tests fail.
**- Maintenance Effort for Tests**: The amount of time and money used to keep automatic test scripts up to date and in good shape.
How UI Automation Testing Will Change in the Future
Since software development is always changing, here are some new ideas and trends that will likely affect the future of UI automation testing:
```
**Code Example:**
# Example of AI-powered testing with Applitools Eyes in Python
import applitools
# Set up Applitools Eyes
eyes = applitools.Eyes()
# Open the website
driver.get(“https://example.com")
# Take a screenshot and validate it
eyes.open(driver, “Example App”, “Home Page”)
eyes.check_window(“Home Page”)
# Close the browser
driver.quit()
```
**- AI-Powered Testing**: Technologies like artificial intelligence (AI) and machine learning (ML) are changing the way testing is done by handling different parts of the testing process. AI-powered testing tools can look at huge amounts of test data, find trends, and guess what problems might happen next, making the testing process more efficient and effective. Teams can improve test coverage, cut down on fake results, and get the most out of their testing efforts by using AI.
**- Shift-Left Testing**: This is a new way of thinking about testing that focuses on moving testing tasks earlier in the software development lifecycle (SDLC), starting with the objectives and design phase. By testing early on in the development process, teams can find and fix bugs faster, which lowers the cost and effect of problems later on in the process. Shift-left testing encourages coders and testers to work together, builds a culture of quality, and speeds up feedback loops.
**- Test-Driven Development**: TDD is a fast method for making software that encourages writing tests before writing code. They write failed tests (red), write code to pass the tests (green), and then modify the code to make it better designed and easier to manage. This is called the “red-green-refactor” cycle. TDD supports flexible, loosely tied designs and pushes developers to test their work before writing it.
**- DevOps and Continuous Testing**: During the whole software development process, DevOps methods stress cooperation, automation, and continuous release. Continuous testing is an important part of DevOps As part of the CI/CD process, automatic tests run all the time. Teams can speed up feedback loops, cut down on cycle times, and increase the number of deployments while keeping quality and dependability high by automating testing and blending it into the development process.
**- Shift-Right Testing**: This type of testing focuses on testing in production or near-production settings, which is different from shift-left testing. Shift-right testing includes keeping an eye on and studying real user interactions, feedback, and tracking data to find problems, make sure theories are correct, and keep making software better. Teams can learn a lot about user behavior, speed, and usefulness by using shift-right tests. This lets them make changes and come up with new ideas more quickly.
**- Codeless Test Automation**: Codeless test automation tools are becoming more popular because they let people who aren’t tech-savvy make and run automatic tests without writing code. Most of the time, these tools have easy-to-use interfaces, drag-and-drop features, and visible processes for creating and running tests. Codeless test automation makes testing more open and allows people from all over the company to take part in testing. It also speeds up the adoption of automation techniques.
**- Testing Environments that are Containerized**: Containerization technologies like Docker and Kubernetes are changing how testing environments are set up, controlled, and provided. Containerized testing environments make it easy to run automatic tests on a variety of systems and setups by providing infrastructure that is small, movable, and repeatable. Teams can improve resource use, scaling, and stability by containerizing testing settings.
Developers can stay ahead of the curve, improve testing methods, and make sure that users get high-quality software that meets their changing needs and expectations if they follow these future UI automation testing trends and innovations. When AI is used, shift-left and shift-right methods are used, and containerization and codeless automation are used. The future of UI automation testing looks exciting, transformative, and full of possibilities.
**Conclusion:**
To sum up, UI automation testing is an important part of getting safe releases to production settings. We’ve talked about how UI automation testing has changed over time, its benefits, application strategies, challenges, measurement methods, and possible future trends in this in-depth guide. It’s clear that UI automation testing has many benefits, such as better test coverage, shorter time-to-market, less human work, and higher dependability. Using best practices and adding UI automation testing to the software development lifecycle (SDLC), development teams can lower risks, speed up testing, and confidently produce high-quality software.
In the near future, UI automation testing trends like AI-powered testing, shift-left testing, and test-driven development (TDD) will change the way software is tested and make testing more efficient and effective. Development teams can keep making things better and giving their customers more value by following industry trends and being open to new ideas.
UI automation testing is more than just a tool or a process; it’s a way of thinking, a way of life, and a dedication to making software that works well. In today’s competitive market, companies can build trust, make customers happier, and be more successful by using routine testing and putting security first in updates. **When development teams use UI automation testing as a guide, they can confidently get through the complicated process of making software and deliver software that meets the highest quality and dependability standards.** | coderower |
1,895,995 | How to Set Up Solargraph in VS Code with WSL2 | Introduction Recently, I faced an issue while trying to set up Solargraph in VS Code using... | 0 | 2024-06-21T12:49:32 | https://dev.to/lucasldemello/how-to-set-up-solargraph-in-vs-code-with-wsl2-283b | vscode, ruby, productivity, solargraph | ## Introduction
Recently, I faced an issue while trying to set up Solargraph in VS Code using WSL2 and ASDF for managing Ruby versions. The legacy projects I was working on used Docker, causing conflicts with Ruby versions and resulting in errors when initializing the server. After much research and trial and error, I managed to solve the problem. Here is a step-by-step guide to help other developers who might be facing the same issue.
## Disclaimer
The easiest way to resolve Ruby version issues would be to modify the project's `.tool-versions` file to use a Ruby version compatible with Solargraph. However, in legacy environments, this modification may not be possible due to specific project dependencies or restrictions imposed by the development team. Therefore, this guide provides an alternative solution that does not require changes to the `.tool-versions` file.
## Step-by-Step Solution
### Prerequisites
1. **WSL2 installed**: Follow the [official Microsoft instructions](https://docs.microsoft.com/en-us/windows/wsl/install) to set up WSL2.
2. **VS Code installed**: Download and install [VS Code](https://code.visualstudio.com/).
3. **Linux distribution on WSL2**: For example, Ubuntu.
### Step 1: Set Up Ruby on WSL2 with ASDF
1. **Install ASDF**: In the WSL2 terminal, run the following commands:
`git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.10.0
echo '. $HOME/.asdf/asdf.sh' >> ~/.bashrc
echo '. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc
source ~/.bashrc`
2. **Add the Ruby plugin and install a Ruby version**:
`asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git
asdf install ruby 3.3.2 # Replace with the necessary version
asdf global ruby 3.3.2`
3. **Verify the Ruby installation**:
`ruby -v`
### Step 2: Install Solargraph
1. **Install Solargraph**:
`gem install solargraph`
2. **Verify the Solargraph installation**:
`which solargraph`
### Step 3: Configure VS Code to Use WSL2
1. **Install the "Remote - WSL" Extension**: In VS Code, open the Extensions Marketplace and install the [Remote - WSL](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-wsl) extension.
2. **Open VS Code in WSL2**: In the WSL2 terminal, navigate to your project directory and open VS Code:
`code .`
### Step 4: Configure Solargraph in VS Code
1. **Add the configuration in `settings.json`**: In VS Code opened in the WSL2 environment, open the Command Palette (`Ctrl+Shift+P` or `Cmd+Shift+P`), search for "Preferences: Open Settings (JSON)" and add the following configuration:
```json
{
"solargraph.commandPath": "/home/your_user/.asdf/shims/solargraph",
"solargraph.useBundler": false,
"solargraph.diagnostics": true,
"solargraph.formatting": true
}
```
Replace `/home/your_user/.asdf/shims/solargraph` with the path returned by the `which solargraph` command.
2. **Restart VS Code**: Restart VS Code to apply the new settings.
### Troubleshooting
- **Check permissions and paths**: Ensure that the path specified for Solargraph in `settings.json` is correct and accessible.
- **VS Code Logs**: Check the VS Code logs for more details on the error. Access the logs through the Command Palette (`Ctrl+Shift+P` -> "Output") and select "Solargraph" from the output menu.
## Conclusion

Recentemente, enfrentei um problema ao tentar configurar o Solargraph no VS Code enquanto utilizava o WSL2 e o ASDF para gerenciar versões do Ruby. Os projetos legados que eu estava trabalhando usavam Docker, o que causava conflitos com as versões do Ruby e resultava em erros ao inicializar o servidor. Após muita pesquisa e tentativa e erro, consegui resolver o problema. Aqui está um guia passo a passo para ajudar outros desenvolvedores que possam estar enfrentando a mesma situação.
## Disclaimer
O caminho mais fácil para resolver problemas de versão de Ruby seria modificar o arquivo `.tool-versions` do projeto para usar uma versão do Ruby compatível com o Solargraph. No entanto, em ambientes legados, essa modificação pode não ser possível devido a dependências específicas do projeto ou restrições impostas pela equipe de desenvolvimento. Portanto, este guia fornece uma solução alternativa que não requer mudanças no arquivo `.tool-versions`.
## Passo a Passo para Resolver o Problema
### Pré-requisitos
1. **WSL2 instalado**: Siga as [instruções oficiais da Microsoft](https://docs.microsoft.com/en-us/windows/wsl/install) para configurar o WSL2.
2. **VS Code instalado**: Baixe e instale o [VS Code](https://code.visualstudio.com/).
3. **Distribuição Linux no WSL2**: Por exemplo, Ubuntu.
#### Passo 1: Configure o Ruby no WSL2 com ASDF
- **Instale o ASDF**:
No terminal do WSL2, execute os seguintes comandos:
``` bash
git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.10.0
echo '. $HOME/.asdf/asdf.sh' >> ~/.bashrc
echo '. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc
source ~/.bashrc
```
- **Adicione o plugin Ruby e instale uma versão do Ruby**:
```bash
asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git
asdf install ruby 3.3.2 # Substitua pela versão necessária
asdf global ruby 3.3.2
```
- **Verifique a instalação do Ruby**:
```bash
ruby -v
```
#### Passo 2: Instale o Solargraph
- **Instale o Solargraph**:
``` bash
gem install solargraph
```
- **Verifique a instalação do Solargraph**:
```
which solargraph
```
#### Passo 3: Configure o VS Code para Usar o WSL2
- **Instale a Extensão "Remote - WSL"**: No VS Code, abra o Marketplace de Extensões e instale a extensão [Remote - WSL](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-wsl).
2. **Abra o VS Code no WSL2**: No terminal do WSL2, navegue até o diretório do seu projeto e abra o VS Code:
```bash
code .
```
#### Passo 4: Configure o Solargraph no VS Code
- **Adicione a configuração no `settings.json`**: No VS Code aberto no ambiente WSL2, abra o Command Palette (`Ctrl+Shift+P` ou `Cmd+Shift+P`), procure por "Preferences: Open Settings (JSON)" e adicione a seguinte configuração:
```json
{
"solargraph.commandPath": "/home/seu_usuario/.asdf/shims/solargraph",
"solargraph.useBundler": false,
"solargraph.diagnostics": true,
"solargraph.formatting": true
}
```
Substitua `/home/seu_usuario/.asdf/shims/solargraph` pelo caminho retornado pelo comando `which solargraph`.
- **Reinicie o VS Code**: Reinicie o VS Code para aplicar as novas configurações.
### Solução de Problemas
- **Verifique as permissões e caminhos**: Certifique-se de que o caminho especificado para o Solargraph no `settings.json` está correto e acessível.
- **Logs do VS Code**: Verifique os logs do VS Code para mais detalhes sobre o erro. Acesse os logs através do Command Palette (`Ctrl+Shift+P` -> "Output") e selecione "Solargraph" no menu de saída.
### Conclusão
Com esses passos, você deve conseguir configurar o Solargraph no VS Code utilizando a versão do Ruby gerenciada pelo ASDF no ambiente WSL2, sem a necessidade de modificar o arquivo `.tool-versions` do projeto. Espero que este guia seja útil para resolver problemas semelhantes que você possa encontrar no seu ambiente de desenvolvimento Ruby. | lucasldemello |

1,895,986 | How to Optimize Content Using GenAI Powered Search Analytics? | Technical writers have relied on “lexical search” analytics regarding what keywords have been typed... | 0 | 2024-06-21T12:36:37 | https://dev.to/ragavi_document360/how-to-optimize-content-using-genai-powered-search-analytics-4p25 | Technical writers have relied on “lexical search” analytics regarding what keywords have been typed in the search engine on their knowledge base site for analysis. The typical category of analytics includes article performance, search analytics, feedback, and reports for technical writers on their performance.
Analytics helped technical writers enhance content engagement and user journeys to optimize the knowledge base content continuously. This increased the self-service rate and significantly reducing support tickets.
When optimizing knowledge base content using gen AI-powered search, you have to consider two types of analytics: normal keyword search and prompt-based search.
## Keyword-Based Analytics Vs. Prompt-Based Analytics
Given the proliferation of GenAI technology, many organizations have deployed ChatGPT-like search on their knowledge base. Customers prefer this over keyword-based search. The tables below show the nature of lexical keyword and prompt-based analytics.
## Factors to Consider in Prompt-Based Analytics
Here are the factors you need to look for when enhancing content engagement and user journeys using prompt-based analytics
### Prompt Analysis
Technical writers can access the list of questions (prompts) that have been raised by their customers which gives them better clarity on
- What kind of questions that my customers type in
- What are the key business keywords that are often used by your customers, that relate to your business glossary?
- What types of questions are commonly asked, and what types of similar question
- Why are those questions being typed in, and how do they correlate with other business activities
- What information is most commonly been sought
This helps technical writers better understand the customers’ intent, leading to better business outcomes.

1,895,985 | Mathematics: Timeless Wisdom in a Changing Tech World | Trying to get familiar with binary trees and linked lists data structures over the past few days... | 0 | 2024-06-21T12:35:51 | https://dev.to/trae_z/mathematics-timeless-wisdom-in-a-changing-tech-world-53nf | techevolution, programmingchallenges, datastructures, mathematics | Trying to get familiar with binary trees and linked lists data structures over the past few days brought me to the realization that, unlike programming languages and technologies, mathematics is timeless. P.S. Data structures are deeply rooted in mathematical concepts.
The same textbooks I inherited from my father decades ago, which he himself used half a century ago, I could easily pass down to my son to use in a couple of years' time, and he would still find them immensely useful. For these data structures, I was able to look for and follow my favorite FreeCodeCamp YouTube courses without any fear of consuming deprecated knowledge.
Nothing of such exists, however, in the "technical debt" land of programming. Trying to learn CSS, JavaScript, Python, or even C++ using books or tutorials published 5 to 10 years ago is very much ill-advised, as standards have rapidly evolved. It's even worse when it comes to frameworks and libraries in the ecosystem of these languages; an application built 2 years ago can desperately be in need of maintenance to conform to current best practices.
Christians have it easy right? "Jesus Christ is the same yesterday and today and forever." 😁 | trae_z |

A dedicated YouTuber has unveiled the Pixelbot... | 0 | 2024-06-21T12:23:11 | https://dev.to/hyscaler/ai-powered-lego-printer-turns-imagination-into-mosaic-masterpieces-1853 | The world of Lego just got a whole lot more high-tech! A dedicated YouTuber has unveiled the Pixelbot 3000, a revolutionary AI-powered Lego printer that automates the creation of intricate Lego mosaics. This innovative machine takes inspiration from existing Lego art sets like Da Vinci's Mona Lisa or Hokusai's The Great Wave, but with a significant upgrade: it utilizes artificial intelligence to streamline the entire process.
## How the AI-powered Lego Printer Works
While impressive for its time, Jason Allemann's Bricasso, a previous Lego printer design, relied on a cumbersome process. Users had to manually create mosaic designs, print them on paper, and then scan them for the machine to interpret. The Pixelbot 3000 eliminates this manual step with the help of custom code and AI.
Here's the magic behind the Pixelbot 3000:
- User Input: Users simply type in the artwork they want the AI-powered Lego printer to create.
- AI Image Generation: The prompt is then sent to OpenAI's DALL-E 3, instructed to generate a simplified cartoon-style image sized 1024 x 1024 pixels.
- Image Conversion: The printer's code understands the limitations of its canvas (a 32 x 32 Lego tile grid) and cleverly divides the AI-generated image into this smaller grid. It then samples the color of the center pixel in each square. This intelligent conversion creates a high-contrast, scaled-down image ideal for a Lego mosaic.
- Color Matching: Since Lego bricks come in a limited color palette (around 70, with the Pixelbot 3000 using 15), the final step involves finding the closest color match for each pixel in the scaled image. This ensures the final mosaic accurately reflects the original artwork.

It's a powerful tool for transforming arrays.
{% youtube oystIFwyt4o %}
👉 **[Download eBook - JavaScript: from ES2015 to ES2023](https://qirolab.gumroad.com/l/javascript-from-es2015-to-es2023)**
.
Here's a detailed look at how the `array.map` function works in JavaScript:
### Syntax
```javascript
array.map(callback(currentValue, index, array), thisArg)
```
- **callback**: A function that is called for every element of the array. Each time the callback executes, the returned value is added to the new array.
- **currentValue**: The current element being processed in the array.
- **index**: The index of the current element being processed in the array.
- **array**: The array `map` was called upon.
- **thisArg** (optional): Value to use as `this` when executing the callback.
### Example Usage
1. **Basic Example**
```javascript
const numbers = [1, 4, 9, 16];
const doubled = numbers.map(num => num * 2);
console.log(doubled); // [2, 8, 18, 32]
```
2. **Using Index**
```javascript
const numbers = [1, 4, 9, 16];
const withIndex = numbers.map((num, index) => `${index}: ${num}`);
console.log(withIndex); // ["0: 1", "1: 4", "2: 9", "3: 16"]
```
3. **Converting Data Types**
```javascript
const stringNumbers = ["1", "2", "3"];
const parsedNumbers = stringNumbers.map(str => parseInt(str));
console.log(parsedNumbers); // [1, 2, 3]
```
### Key Points
- **Immutability**: `map` does not change the original array. It creates a new array with the transformed elements.
- **Function Requirement**: `map` requires a callback function. If you just want to copy an array, you should use `slice` or the spread operator.
- **Consistency**: The new array will always have the same length as the original array.
### Practical Use Cases
1. **Transforming Data**
Converting an array of objects into an array of specific property values:
```javascript
const users = [
{ id: 1, name: "John" },
{ id: 2, name: "Jane" },
{ id: 3, name: "Doe" }
];
const userNames = users.map(user => user.name);
console.log(userNames); // ["John", "Jane", "Doe"]
```
2. **Extracting Data**
Extracting URLs from an array of objects:
```javascript
const links = [
{ label: "Google", url: "http://google.com" },
{ label: "Facebook", url: "http://facebook.com" },
{ label: "Twitter", url: "http://twitter.com" }
];
const urls = links.map(link => link.url);
console.log(urls); // ["http://google.com", "http://facebook.com", "http://twitter.com"]
```
3. **Combining with Other Methods**
Combining `map` with `filter` to first filter an array and then transform it:
```javascript
const numbers = [1, 2, 3, 4, 5, 6];
const evenSquares = numbers.filter(num => num % 2 === 0).map(num => num * num);
console.log(evenSquares); // [4, 16, 36]
```
### Conclusion
The [`array.map` function](https://qirolab.com/posts/mastering-the-arraymap-method-in-javascript) is a fundamental method in JavaScript for transforming arrays. It allows for the application of a function to each element of an array, resulting in a new array with the transformed elements. Understanding and using `map` effectively can lead to cleaner, more readable code, especially when dealing with data transformation tasks.

It also helps to keep a company competitive in the market and boost production. The rapid evolution of technology and consumer preference for mobile devices highlight the critical role that mobile applications play in company strategy.
Creating mobile applications is critical to a business’s success in the modern digital world. Here’s a thorough analysis of the reasons mobile apps are so important:
Increased Interaction with Customers
Customers may explore, shop, and interact with brands conveniently with mobile applications, which operate as a direct channel. Apps may make purchases easier, notify customers of new features or discounts, and push notifications—all of which increase user engagement. For example, apps are often used by e-commerce companies to send customers personalized offers, which can dramatically boost conversion rates.
Better Support for Customers
Mobile applications are a great way to deliver top-notch customer support. Without requiring direct communication, features like in-app chats, support tickets, FAQs, and virtual assistants can assist in resolving user difficulties. This degree of response not only makes consumers happy but also fosters enduring loyalty by demonstrating that the company values their time and convenience.
Efficiency of Operations
Mobile apps can also increase operational efficiency by automating processes and giving staff members the resources they need to do their duties more successfully. Apps that interface with a business’s backend systems, for instance, can expedite procedures like order processing, inventory management, and customer support. Significant time savings and mistake reduction are possible with this combination.
Analytics and Data Gathering
Mobile apps are valuable sources of user data. They provide insights for business decisions. Tracking in-app behavior reveals preferences, spending trends, and demographics. Businesses gain crucial understanding from this data. This information is essential for enhancing product offers, customizing marketing campaigns, and enhancing user experience as a whole.
An advantage over competitors
In a market where customers are using digital solutions more and more, having a mobile app can provide you a big competitive edge. Apps assist in creating a contemporary brand image for a company in addition to increasing consumer accessibility. Businesses who don’t have mobile applications run the danger of losing out to rivals who use app-based sales and marketing techniques.
Marketing at a Low Cost
Compared to traditional ads, mobile apps offer cost-effective marketing. They ensure easy access to products anytime, anywhere. Businesses can stay visible on consumers’ devices. This facilitates consistent engagement with goods and services. Additionally, apps can contain a range of marketing activities, such as cross-promos with other services, promotions, and adverts, to maximize visibility and engagement at a comparatively cheap cost.
Basics Of Mobile App Development
Whether they are developers or business owners commissioning an app, everyone entering this industry must understand the fundamentals of mobile app development. The following are the essential basics and elements of mobile app development:
UX (User Experience) And UI (User Interfance)
When developing mobile apps, user interface and user experience are the 2 main components. They directly affect how users engage with the app. User interface design (UI design) focuses on visual components. These components include button placements, colors, and typography. They give an application its aesthetic appeal and functionality.
On the other side, UX design emphasizes the overall feel and flow of the application. It makes sure people can move around it with ease and accomplish their goals without getting lost. Efficient and engaging user experience design is the aim of good user interface/user experience design. As a result, user retention rises and bounce rates fall.
Frontend and Backend Development
Frontend development in the context of mobile apps refers to the area of the app that users directly interact with. It entails putting design components into practice and writing the code necessary for the app to function on a device. For mobile apps, frontend developers employ technologies like Kotlin for Android apps and Swift for iOS apps to guarantee optimum performance and device integration.
The server side of the application, which is essential for handling user actions, is the focus of backend development. Database administration, API integration, and server management are all included. Backend developers make sure that information reaches the app server and users without interruption, preserving the security and functionality of the program.
APIs
Sets of protocols known as application programming interfaces (APIs) enable communication between software components. APIs are used in mobile app development to integrate external services. These services include payment gateways, social network sharing, and weather updates. This integration improves the app’s functionality.
For instance, a travel app might use weather forecasting APIs. These APIs provide users with recent local weather information for their destinations.
Testing and Deployment
To ensure a mobile app’s quality and security, testing is a crucial development stage. This stage involves various testing techniques to identify and fix defects. These techniques include unit testing, integration testing, and user acceptability testing (UAT). Thorough testing occurs before the app is publicly available. It enhances the software’s security, usability, and stability.
The last stage is deployment. During this stage, the app is submitted for approval and publication. It is sent to app stores like Google Play and the Apple App Store. This involves meeting specific requirements. These requirements relate to performance, aesthetics, and security standards. Each platform sets its own standards. The app is made public once it is authorized, and developers are then required to keep an eye on user input and performance to fix any new problems that may arise.
How to Identify Low-Quality Mobile App Development Work?
Finding low-quality mobile app development work is essential to making sure your investment produces an application that is effective, efficient, and easy to use. The following are specific indicators of subpar mobile app development:
Inadequate User Interface and Experience
The user interface of a mobile app creates the first impression. A poor user interface (UI) can appear outdated and unintuitive. It may also fail to follow current design trends, often indicating low-quality development. Similarly, a bad user experience (UX) is marked by hard-to-access features and clumsy navigation. Interactions that don’t feel natural or fluid further indicate poor UX design. High-quality apps, on the other hand, feature smooth and user-friendly experiences. They have neat, captivating interfaces that enhance user satisfaction.
Regular App Bugs and Crashes
An application that crashes a lot or has a lot of problems is a dead giveaway for poor development. To guarantee stability, quality development involves extensive testing on a variety of hardware and operating systems. The user experience is hampered by frequent crashes, which can also seriously harm a brand’s reputation. An app most likely omits important testing and quality assurance processes if it does not function consistently during user interactions.
Hesitant loading times and performance
The key to keeping users is performance. Applications that lag or take a long time to load can annoy users, which lowers retention rates and generates bad ratings. Performance is optimized through good app creation, so even with high loads, the app will run smoothly, load swiftly, and handle data efficiently.
Absence of Safety Measures
Safeguarding sensitive user data requires a high level of security. Poor-quality apps frequently ignore security precautions or execute them incorrectly, making user data susceptible to security breaches. Lack of data encryption, easily circumvented authentication, and noncompliance with industry security standards are indicators of insufficient security. To protect its users, well-developed software will give top priority to strong security measures.
Insufficient Updates and Customer Support
Quality-conscious developers will give their apps ongoing support and frequent updates, addressing issues and enhancing functionality in response to user input. A lack of updates or support for an app could indicate that its creators are not interested in seeing it through to the end. Maintaining compatibility with new devices and operating systems requires regular updates.
Failure to Follow App Store Policies
Regarding app functioning, quality, and appearance, there are strict requirements available on both the Google Play Store and the Apple App Store. These requirements are frequently not met by the apps that are rejected from these stores, which is a sign of subpar development techniques. One fundamental but important component of developing a high-quality mobile app is adhering to app store requirements.
Steps to Avoid Low-Quality Mobile App Development
Businesses should take a few proactive measures to guarantee they receive a well-designed and functional product and steer clear of low-quality mobile app development. These are some thorough strategies:
Perform Extensive Research
Start by conducting extensive research on possible developers. Look for portfolios that highlight their prior work and peruse evaluations and testimonies from clients. Consider their background in your sector as well as their knowledge of the particular platforms or technology you need. This stage assists you in determining their market reputation as well as their suitability for your project.
Establish Specific Goals and Requirements
Identify your app’s objectives, target market, and necessary features before starting any development work. It’s critical to communicate these criteria to your development team and have a clear vision. This lowers the chance of misunderstandings and reworks while also guaranteeing that the finished product meets your company’s needs.
Make Effective Communication Your Top Priority
Select a developer or development team that you can readily and productively communicate with. Throughout the development phase, it’s critical to keep lines of communication open and provide regular updates. This lowers the possibility of project failure by enabling you to make prompt judgments, offer feedback, and change project specifications as needed.
Demand a Detailed Project Plan
Ensure the developer provides a comprehensive project plan. This plan should include deadlines, checkpoints, and deliverables. A well-organized plan helps manage the project effectively. It also aids in tracking progress. Moreover, it establishes clear expectations for everyone involved. The stages of development, testing, and deployment should be described, together with any modifications made in response to test results.
Stress User Experience (UX) Design
High-caliber mobile applications deliver excellent user experiences. Make sure your developer gives UX design—which ought to be simple, interesting, and approachable—a lot of thought. To ensure the app fits its intended customers’ demands, think about spending money on UX research during the design phase, such as user testing and feedback sessions.
Include Comprehensive Testing
Before launching your app, make sure it has undergone comprehensive testing on a variety of hardware and operating systems to find and address problems and usability concerns. Unit, integration, performance, and user acceptability testing are all included in this. Ensuring the app remains reliable and of high quality requires a thorough testing period.
Prepare for Updates and Post-Launch Support
Excellent development doesn’t stop with the product’s release. To maintain the app’s relevance and functionality as user needs change and new technologies arise, post-launch maintenance and frequent upgrades are important. Make sure that continuing maintenance and support are included in your agreement with the developer.

1,895,956 | ES-6 What is it? | Let's check the acronym first ES = ECMAScript (ECMA - "European Computer Manufacturers... | 0 | 2024-06-21T12:07:47 | https://dev.to/harshasrisameera/es-6-what-is-it-2ibd | javascript, programming, es6, react | Let's check the acronym first
ES = ECMAScript (ECMA - "European Computer Manufacturers Association")
ES is a standard for scripting languages. The most popular language among them is Javascript. It was first introduced in 1997.
When you hear people say ES5, ES6, etc, they are referring to a version of ECMAScript. ES6 is nothing but the standard released in 2015, i.e., ECMAScript 2015. There are many other standards of ES - ES7 (ECMAScript 2016), ES8 (ECMAScript 2017), etc.
### Why is ES6 so important?
That is because it was the biggest update since its release. It is the 6th edition of the ECMAScript Language Specification and adds significant new syntax for writing complex applications. The subsequent updates are much smaller so the vast majority of the things you need to be familiar with are the things that were standardized in ES6.
### Why should we even learn it?
ES6 has a lot of forward-thinking ideas attached to it and is a really exciting programming language to use. It is really fast and efficient. ES6 is 100% backward compatible. This means that when you start writing ES6, you can start with the regular JavaScript you know and love. You can then slowly start embracing new features and adopting the aspects of ES6 that make your life easier as a developer as you get more comfortable over time.
**In Short**:React Js recommends using the ES6 standard of Javascript.
Here goes some important ES6 features:
• [let and const](https://www.geeksforgeeks.org/difference-between-var-let-and-const-keywords-in-javascript/)
• [Arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions)
• [Destructuring](https://www.w3schools.com/react/react_es6_destructuring.asp)
• [The spread and rest operators](https://www.freecodecamp.org/news/javascript-spread-and-rest-operators/)
• [Template literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals)
• [Modular javascript using export/imports ](https://www.w3schools.com/js/js_modules.asp#:~:text=You%20can%20import%20modules%20into,Default%20exports%20are%20not.)
Hope this info gives some idea about ES6 :)

1,895,070 | when should you quit working on an idea? | Millions of business ideas, SaaS, and startup ideas fail everyday. As a business graduate myself,... | 0 | 2024-06-21T12:05:38 | https://dev.to/ohchloeho/when-should-you-quit-working-on-an-idea-5h6 | startup, saas, beginners, career | Millions of business ideas, SaaS, and startup ideas fail everyday. As a business graduate myself, I’ve learnt something quite important about recognizing the potentials of an idea before the costs to prove its worth overwhelms its true value.
Every idea sparks from a pain point and surrounds it to act as a painkiller. But what frequently happens is that we fall so in love with our ideas that we forget the problems they’re supposed to be solving. And just like bugs or inefficiencies in our programs, our obsession with these ideas often manifests and turns into wasted time and dollars.
## Making up the problem
The #1 trap I fell into when I started my first hackathon project was exaggerating the problem. It was simple. The initial problem was that Slack workspace owners had to remove inactive or unused channels manually and one at a time. Since this is an incredibly time-consuming process for companies with huge workspaces, say 1000-1500 users, a Slack Bot can be built to 1. monitor all channels within a workspace, 2. set a threshold of inactivity, and 3. archive channels that have been inactive over the threshold.
So I started building the Bot with these 3 main features in mind. A few hours later, I thought, "What if the bot could automatically send messages to admins about channel activity, and flag any messages that contain data prone to insecurity or any anomalies like harsh language / vulgarities?" Now you may think that I'm only thinking these because I was done building the initial 3 main features, but I wasn't even halfway through the first.
Now I've got about another 6 features I want my bot to have. It's the following week with about 3 hours left before the due time and only 1 feature package passed release checks. I had to present my idea with a beautiful slide deck only to spectacularly fail at showing a working demo.
Now I know what you're thinking, if I worked with another developer or a team I’d probably be able to get them to build all the features within the time frame. Yes, that's exactly what I thought as well, until one of the lecturers hit me with this:
"Imagine you're a potential user of this bot. You're on Slack and you've got about 200 channels that are inactive and you want to archive them. Since Slack has no built in functionality to do this in bulk, you go to Google to search for a solution and you land on this bot.
You click on the webpage link, read the documentation on how to use it, and get overwhelmed with a whole bunch of features you don't need. What do you do then?"
Which was a really good point because as a user, I would simply tab back to Google and search for a better solution. I wouldn't have even given my slack bot a second thought or even another 20 seconds to look through. Yes it's brutal, but it’s true, because if I wouldn’t pick my own bot, I’ll assume that not many people would either.
Having gone through all of that, I just spend a half day on each idea I had from then on. Build one feature and get it to ship, as fast as possible. Extra features are like the sides of fast food meals. They might look really appetizing, but a whole lot of them would rack up in prices and make you too full for your burger which is the hero.
## There's always someone doing it better
Now even though I gave up on the idea post-hackathon, I was still itching from the epic fail. So I Googled "archive slack channels automatically" and a whole bunch of well-built, simplistic, easy to implement solutions appeared. One of which was Channitor, which solved the problem immediately within 2-3 clicks of being added to a Slack workspace.
Of course there are hundreds of solutions to the same problem. Someone's always doing it better and someone's always got the better approach. But what really humbled me was that there _is_ no one-shoe-fits-all approach. Every single thing has its own specific purpose, just like how a Mustang is to be driven with style, and a Toyota is to be driven with comfort. You wouldn't drive a Toyota to a drag race and you definitely wouldn't try to fit an entire family in a Mustang.
The lesson truly learnt here is that no matter what we're doing, building, or creating, there's always someone doing it better. But what really helps propel us is the things that make what we build different from the others. A product isn’t just the features it represents, it’s the feeling that people get when owning it. I've understood this very clearly from the music industry since it is as highly competitive as tech or maybe even more. Someone's always got a better voice, a better guitar hook, a better beat. But what sets me apart is what my art truly means and how I tell my stories through them.
## What I’ve learnt from quitting early
Yes, just like nicotine and alcohol, it’s better and easier to quit early, and while the risks are invisible. A bad idea will never seem like one at the start. It might even seem like the best idea ever. But don’t fret, failures are never the end and there’s always a step up to a better application and an award-winning idea. Here’s what I’ve learnt mostly from my spectacular failures:
1. Clarity is key - be able to define the problem statement clearly, and if possible in one short sentence
2. Do proper research - talk to people who potentially have the problem you’re trying to solve and get their insights on how they’ve looked for solutions, what solutions they’ve landed on, what works for them and what doesn’t
3. Don’t fall prey to Shiny object syndrome - focus on the main feature instead of getting distracted with a million other potential features. Most of these probably wouldn’t even make a difference until your idea blows up anyway
3. Treat feedback like food - listen to your potential users! They’re the ones who are going to be relying on what you’re building anyway. How would you feel if the waiter taking your order gets it wrong twice or even thrice?
### end
Well if you’ve made it this far into this read, please leave a comment and let me know what you think! As this is my second post do share some thoughts on my writing as well, remember I take feedback like it’s food :)

1,895,946 | Diferenças entre o jest.spyOn e jest.mock | Sim, existem diferenças importantes entre jest.mock e jest.spyOn, embora ambos sejam usados para... | 27,693 | 2024-06-21T12:02:18 | https://dev.to/vitorrios1001/diferencas-entre-o-jestspyon-e-jestmock-5035 | jest, testing, javascript, mock | Sim, existem diferenças importantes entre `jest.mock` e `jest.spyOn`, embora ambos sejam usados para criar mocks em testes. Vamos explorar as diferenças e quando usar cada um.
## **jest.mock**
### Uso
`jest.mock` é usado para mockar módulos inteiros. Isso é útil quando você deseja substituir um módulo completo, seja ele uma biblioteca de terceiros ou um módulo local, com uma versão mockada.
### Comportamento
Quando você usa `jest.mock`, Jest automaticamente substitui todas as funções exportadas pelo módulo mockado com versões mockadas.
### Exemplos
```javascript
// Suponha que temos um módulo `utils.js` com uma função `calculate`.
import { calculate } from './utils';
// Testando um componente que usa a função `calculate`.
import MyComponent from './MyComponent';
// Mocka o módulo `utils`.
jest.mock('./utils', () => ({
calculate: jest.fn(),
}));
test('should call calculate function', () => {
calculate.mockReturnValue(42);
render(<MyComponent />);
expect(calculate).toHaveBeenCalled();
});
```
### Quando Usar
Use `jest.mock` quando você quiser mockar todas as funções de um módulo ou quando quiser substituir completamente um módulo.
## **jest.spyOn**
### Uso
`jest.spyOn` é usado para espionar métodos em objetos. Isso é útil quando você deseja manter a implementação original do método, mas ainda assim observar como ele é chamado e/ou fornecer valores de retorno personalizados.
### Comportamento
`jest.spyOn` cria uma versão mockada de uma função existente, permitindo que você mantenha a implementação original ou a substitua conforme necessário.
### Exemplos
```javascript
// Suponha que temos um módulo `utils.js` com uma função `calculate`.
import * as utils from './utils';
// Testando um componente que usa a função `calculate`.
import MyComponent from './MyComponent';
test('should call calculate function', () => {
// Espiona a função `calculate`.
const spy = jest.spyOn(utils, 'calculate').mockReturnValue(42);
render(<MyComponent />);
expect(spy).toHaveBeenCalled();
});
```
### Quando Usar
Use `jest.spyOn` quando você quiser espiar uma função específica em um módulo sem substituir todo o módulo. É especialmente útil quando você quer observar chamadas para métodos em instâncias de classes ou objetos específicos.
## Comparação Direta
### **jest.mock**
- **Escopo**: Mocka módulos inteiros.
- **Substituição**: Substitui todas as funções exportadas pelo módulo com versões mockadas.
- **Uso**: Ideal para mockar bibliotecas de terceiros ou módulos locais inteiros.
### `jest.spyOn`
- **Escopo**: Espiona métodos específicos em objetos ou instâncias de classes.
- **Substituição**: Cria uma versão mockada de uma função existente, permitindo observar chamadas e substituir o comportamento.
- **Uso**: Ideal para observar e mockar métodos específicos em objetos ou instâncias, mantendo a implementação original disponível.
## Exemplo Completo
### Arquivo `utils.js`
```javascript
export const calculate = (a, b) => a + b;
```
### Arquivo `MyComponent.js`
```javascript
import React from 'react';
import { calculate } from './utils';
const MyComponent = () => {
const result = calculate(2, 3);
return <div>{result}</div>;
};
export default MyComponent;
```
### Teste com `jest.mock`
```javascript
import React from 'react';
import { render, screen } from '@testing-library/react';
import MyComponent from './MyComponent';
import { calculate } from './utils';
jest.mock('./utils', () => ({
calculate: jest.fn(),
}));
test('should call calculate function', () => {
calculate.mockReturnValue(42);
render(<MyComponent />);
expect(calculate).toHaveBeenCalled();
expect(screen.getByText('42')).toBeInTheDocument();
});
```
### Teste com `jest.spyOn`
```javascript
import React from 'react';
import { render, screen } from '@testing-library/react';
import MyComponent from './MyComponent';
import * as utils from './utils';
test('should call calculate function', () => {
const spy = jest.spyOn(utils, 'calculate').mockReturnValue(42);
render(<MyComponent />);
expect(spy).toHaveBeenCalled();
expect(screen.getByText('42')).toBeInTheDocument();
});
```
## Conclusão
Tanto `jest.mock` quanto `jest.spyOn` são ferramentas poderosas no Jest para mockar funções e módulos. A escolha entre eles depende do contexto do teste e do que você está tentando alcançar. `jest.mock` é ótimo para substituir módulos inteiros, enquanto `jest.spyOn` é ideal para observar e mockar métodos específicos sem substituir todo o módulo. | vitorrios1001 |

1,895,039 | Step Guide on how to create and connect to a Linux VM using a Public key | Creating a Linux virtual machine (VM) on Microsoft Azure involves several steps. Here’s a... | 0 | 2024-06-21T12:00:38 | https://dev.to/ikay/step-guide-on-how-to-create-and-connect-to-a-linux-vm-using-a-public-key-2nna | virtualmachine, linux, resources, deployment | Creating a Linux virtual machine (VM) on Microsoft Azure involves several steps. Here’s a comprehensive guide to help you set up an Azure Linux VM:
**Step-by-Step Guide:**
If you don't have an Azure subscription, create a free account before you begin.
Sign in to Azure Portal:
Go to portal.azure.com and sign in with your Azure account.
**Create a Resource Group (Optional):**
A resource group is a logical container for grouping your Azure resources. If you don’t have one already, you can create it:
In the Azure Portal, click on **Resource groups** in the left-hand menu.
Click on **+ Add** to create a new resource group.
Provide a name, choose a subscription, and select a region. Click **Review + create**, then **Create**.
**Create a Virtual Machine:**
Search for and select **Virtual machine**.
Navigate to the Virtual machines page, click on **Create**, and then select **Virtual machine**. This action opens the Create a **virtual machine** page then select **Azure virtual machine.**
On the **Basics** tab, ensure the appropriate Azure subscription is selected under **Project details.** Opt to **create a new** resource group name or select an existing one.
In the **Instance details** section, enter a name for your VM as the name for the **Virtual machine.**
**Region:** Select the region where your VM will be deployed.
**Image:** Choose your Linux distribution (Ubuntu Server 20.04 LTS - x64 Gen2 (free services eligible)
**Security type:** Select “Standard”.
**VM architecture:** x64
**Size:** Select an appropriate VM size based on your requirements and budget.
Choose SSH public key under **Administrator account**.
Enter **azureuser** as the default Username.
Keep the default setting for **SSH public key source**, which is **"Generate new key pair"**, and name the Key pair **TanikLinux_key** which is auto generated.
**If using SSH public key:** Enter your SSH public key data or browse to upload your public key file.
**If using password:** Enter a username and password for SSH access.
In the **Inbound port** rules section under
**Public inbound ports**, opt for **"Allow selected ports".** Then, from the drop-down menu, select **SSH (22) and HTTP (80).**
Review the settings you’ve configured for your VM, then click the **Review + create** button located at the bottom of the page to validate the configuration.
Maintain the default settings for other options. Note that the default size and pricing displayed are illustrative; actual size availability and pricing vary depending on your region and subscription.
After Validation passed, on the Create a virtual machine page, review the details of the VM you are about to create. When ready, click on the **Create** button to deploy your Azure Linux VM.
Azure will now provision and deploy your VM based on the settings you specified.
Once the **Generate new key pair** window appears, choose **Download private key and create resource.** Your key file will download as **TanikLinuxVM_key.pem.** Ensure you note the download location of the .pem file, as you will need its path in the next step.
After the deployment completes, click on
**Go to resource** to access your VM via SSH.
On the page for your new VM, select the public IP address and copy it to your clipboard.
**Connecting to Virtual Machine:**
Establish an SSH connection to the virtual machine:
On a Windows machine, search for a command prompt and click **Run as administrator**.
Click on your download to get your key file and ensure you note the download location of the .PEM file, then you right click on your .PEM File and select on **Properties** to locate your file path as you will need its path in the next step.
For connection you will need your **command prompt, username and the IP address** to run on your terminal. In your command prompt, initiate an SSH connection to your virtual machine and substitute the VM's IP address for the placeholder, and replace the file path with the actual path where the key file was downloaded.(`ssh -i "/path/to/your/private-key-file.pem" username@your-vm-public-ip`)
**Tip**
You can reuse the SSH key you created for future Azure VMs by selecting **Use a key stored in Azure for SSH public key source.** Since you already have the private key on your computer, there's no need to download anything.
**Install web server**
To see your VM in action, install the NGINX web server. From your SSH session, update your package sources and then install the latest NGINX package.
1. sudo apt-get -y update
2. sudo apt-get -y install nginx
When done, type exit to leave the SSH session.
**View the web server in action**
To view the default NGINX welcome page, use any web browser to access the VM's public IP address as the web address. You can find the public IP address on the VM overview page or in the SSH connection string you used earlier.
**Clean up resources**
**Delete resources**
When no longer needed, delete the resource group, virtual machine, and all related resources:
- On the Overview page of the VM, click on the **Resource group** link.
- At the top of the resource group page, select
**Delete resource group.**
- A page will open warning you that you are about to delete resources. Type the name of the resource group and select **Delete** to finish deleting the resources and the resource group.
**Auto-shutdown**
If you are still in need of the VM, Azure provides an Auto-shutdown feature for VMs to help manage costs and to avoid been billed for unutilized resources:
1. On the **Operations** section for the VM, select the **Auto-shutdown** option.
2. Configure the auto-shutdown time on the following page by selecting **On** to enable and setting a suitable time that is workable by you.
3. Once configured, click **Save** at the top to activate the Auto-shutdown settings.
**Additional Information:**
Be mindful of Azure VM pricing, especially the cost implications of VM size and usage. Always follow best practices for securing your Azure VM, such as using SSH keys instead of passwords where possible, configuring network security groups, and applying OS updates regularly.

1,895,785 | Why CLIs are STILL important | Command Line Interfaces (CLIs) seem old-fashioned in the age of graphical user interfaces (GUIs) and... | 0 | 2024-06-21T12:00:00 | https://cyclops-ui.com/blog/2024/06/21/why-cli-important/ | kubernetes, devops, opensource, beginners | Command Line Interfaces (CLIs) seem old-fashioned in the age of graphical user interfaces (GUIs) and touchscreens, but they remain essential tools for developers. You may not realize it, but they are used far more often than you might think. For example, if you use `git` commands over the terminal, you're likely engaging with a CLI on a daily basis.
To give you some background, I work on Cyclops, a tool that provides a graphical user interface for developers to configure and deploy their applications in Kubernetes. Given my employment, why would I, of all people, emphasize the importance of command-line interfaces?
### Support us 🙏
We know that Kubernetes can be difficult. That is why we created Cyclops, a **truly** developer-oriented Kubernetes platform. Abstract the complexities of Kubernetes, and deploy and manage your applications through a UI. Because of its platform nature, the UI itself is highly customizable - you can change it to fit your needs.
We're developing Cyclops as an open-source project. If you're keen to give it a try, here's a quick start guide available on our [repository](https://github.com/cyclops-ui/cyclops). If you like what you see, consider showing your support by giving us a star ⭐
## Why CLIs 🤔
Command-line interfaces (CLIs) are **incredibly fast** for getting things done. They let you perform actions with simple, direct commands, which is especially useful for repetitive tasks. For example, you can search for files or oversee the various programs and services running on your computer with just a few commands. However, this speed is only accessible to those who know the necessary commands.
CLIs also enable fast **remote access** to machines and servers. Using tools like SSH, you can connect to remote systems from anywhere, allowing you to maintain servers that aren’t physically nearby. Plus, because CLIs are lightweight, they use minimal bandwidth, making remote operations more efficient and reliable.
These are great benefits of having a CLI, but why would Cyclops be interested in developing one? The answer is automation.
### Automation and CI/CD ⚙️
When I talk about automation, I mean writing scripts to handle repetitive tasks, ensuring they are done the same way every time, saving a lot of time. You can automate everything from simple file operations to complex deployments. Automations boost efficiency and reduce the chance of human error since the scripts perform tasks consistently every time they run.
Automation is a standard practice in the software development lifecycle (just think of GitHub actions). **If Cyclops had a CLI, it would allow it to integrate into larger systems for deploying applications, like CI/CD pipelines.**
You could use Cyclops’s UI to make it easier for developers to configure and deploy their applications in Kubernetes clusters, and a CLI would allow you to automate any part of that process.
For example, once you create a template and publish it on GitHub, GitHub actions could automatically connect the template to your Cyclops instance using our CLI. This would **allow your developers instant access to each new template or even any update the template receives**. More on automation in future blog posts… 😉
## Cyclops CLI - `cyctl` 🔅
We didn't want to miss out on the advantages of a CLI, but initially, we struggled to find the time to develop it. However, our community has grown significantly over the past few months, and since we are an open-source project, we began opening issues to kickstart the development of our CLI.
Thanks to our amazing community, we realized that our CLI was closer to realization than we had thought. And just a couple of days ago, [Homebrew](https://formulae.brew.sh/formula/cyctl#default) received a new package - our very own `cyctl`!
## Open Source Magic ✨
We are very proud to say that `cyctl` is a **community-driven project**. While the Cyclops team has been overseeing every change and reviewing every PR, most of the features have been developed by our contributors!
If you're excited about making Kubernetes easier for developers and want to contribute to our CLI or any other part of our project, we’d love to have you on board. Come join us on [Discord](https://discord.com/invite/8ErnK3qDb3) to connect, collaborate, and be a part of something great!

description: Business logic can bloat React components and make them difficult to test. In this article, we discuss how extracting them to hooks in combination with dependency injection can improve maintainability and testability.
---
_The unopinionated nature of React is a two-edged sword:_
- _On the one hand, you get freedom of choice._
- _On the other hand, many projects end up with a custom and_ _**often messy architecture**__._
_This article is the sixth part of a series about software architecture and React apps where we take a code base with lots of bad practices and refactor it step by step._
Previously,
- [we created the initial API layer and extracted fetch functions](https://profy.dev/article/react-architecture-api-layer-and-fetch-functions)
- [added data transformations](https://profy.dev/article/react-architecture-api-layer-and-data-transformations)
- [separated domain entities and DTOs](https://profy.dev/article/react-architecture-domain-entities-and-dtos) and
- [introduced infrastructure services using dependency injection](https://profy.dev/article/react-architecture-infrastructure-services-and-dependency-injection)
All this to isolate our UI code from the server and increase testability.
But we’re not done yet.
In this article, we’re moving closer to the components. From my experience, in many React apps, there’s no real separation between business logic and UI code. There’s no consensus about where to put logic so it often ends up in the component, a custom hook, or a utility file. This can lead to code that is hard to understand and difficult to test.
And that’s exactly what we’ll address here.

## Problematic code example: Business logic mixed with UI logic
Let’s have a look at a problematic code example. Here’s a component that renders a form with a submit handler attached. The submit handler
- updates some UI state
- checks some pre-conditions regarding the users involved
- saves an image and creates a reply
- and finally updates the UI state again.
```typescript
// src/components/shout/reply-dialog.tsx
import MediaService from "@/infrastructure/media";
import ShoutService from "@/infrastructure/shout";
import UserService from "@/infrastructure/user";
...
const ErrorMessages = {
TooManyShouts:
"You have reached the maximum number of shouts per day. Please try again tomorrow.",
RecipientNotFound: "The user you want to reply to does not exist.",
AuthorBlockedByRecipient:
"You can't reply to this user. They have blocked you.",
UnknownError: "An unknown error occurred. Please try again later.",
} as const;
export function ReplyDialog({
recipientHandle,
children,
shoutId,
}: ReplyDialogProps) {
const [open, setOpen] = useState(false);
const [isLoading, setIsLoading] = useState(true);
const [replyError, setReplyError] = useState<string>();
...
async function handleSubmit(event: React.FormEvent<ReplyForm>) {
event.preventDefault();
setIsLoading(true);
const me = await UserService.getMe();
if (me.numShoutsPastDay >= 5) {
return setReplyError(ErrorMessages.TooManyShouts);
}
const recipient = await UserService.getUser(recipientHandle);
if (!recipient) {
return setReplyError(ErrorMessages.RecipientNotFound);
}
if (recipient.blockedUserIds.includes(me.id)) {
return setReplyError(ErrorMessages.AuthorBlockedByRecipient);
}
try {
const message = event.currentTarget.elements.message.value;
const files = event.currentTarget.elements.image.files;
let image;
if (files?.length) {
image = await MediaService.saveImage(files[0]);
}
const newShout = await ShoutService.createShout({
message,
imageId: image?.id,
});
await ShoutService.createReply({
shoutId,
replyId: newShout.id,
});
setOpen(false);
} catch (error) {
setReplyError(ErrorMessages.UnknownError);
} finally {
setIsLoading(false);
}
}
return (
<Dialog open={open} onOpenChange={setOpen}>
{/* more JSX here */}
</Dialog>
);
}
```
Fairly straightforward, right? There’s quite a bit of code inside the submit handler but what can we do!?
## The problem: Mixed concerns and low testability
The thing is that **the component has quite a lot of responsibilities**. Some of these fall well into the concern of a UI component like
- rendering the UI (doh),
- handling the submit event,
- or updating the loading or error state.
But much of the code in the submit handler has nothing to do with UI.
Most of the code is data validation and orchestrating calls to services / Rest APIs. **That’s business logic and can be isolated from the UI framework.**
Imagine we wanted to migrate from React to any other future UI library. We’d have to untangle this mixture of UI and business logic.
Ok, that’s an unlikely event far in the future.
More urgent is this question: **How would you test this component?**
Do I hear “integration tests”? I know, integration tests have become very popular in the React community. Especially thanks to React Testing Library and its premise to test an application from the user’s perspective.
But in this case, **we would need to jump through a few hoops to test all the different branches.** Each return statement represents one branch. Plus the catch block at the end.
So we have test scenarios like:
- A user who shouted more than 5 times and one that didn’t.
- A recipient that doesn’t exist and one that has blocked the current user.
- Failing API requests in the services that trigger the catch block.
- And finally the happy path.
**Yes, we can test this with integration tests.** We could mock the requests with e.g. Mock Service Worker. Then we’d render the app, fill in the form inputs, click the submit button, and check that the UI shows the correct result.
But **this is relatively complex** as we need to set up different mock requests. Additionally, **these tests would be relatively slow** as we’d have to walk through the same UI interactions for each test.
Let’s have a look at an alternative approach.
[](https://profy.dev/article/react-architecture-business-logic-and-dependency-injection#newsletter-box)
## The solution: Extracting business logic and using dependency injection
[Similar to the previous article](https://profy.dev/article/react-architecture-infrastructure-services-and-dependency-injection), the idea is to move the business logic unrelated to the UI to a separate function. We then create a custom hook to facilitate dependency injection. This helps us simplify our tests: No need for an integration test for each branch. Instead we can unit test the business logic.
### Step 1: Extracting business logic to a use-case
We start by extracting all the business logic into a new function in a new file.
```typescript
// src/application/reply-to-shout.ts
import MediaService from "@/infrastructure/media";
import ShoutService from "@/infrastructure/shout";
import UserService from "@/infrastructure/user";
interface ReplyToShoutInput {
recipientHandle: string;
shoutId: string;
message: string;
files?: File[] | null;
}
const ErrorMessages = {
TooManyShouts:
"You have reached the maximum number of shouts per day. Please try again tomorrow.",
RecipientNotFound: "The user you want to reply to does not exist.",
AuthorBlockedByRecipient:
"You can't reply to this user. They have blocked you.",
UnknownError: "An unknown error occurred. Please try again later.",
} as const;
export async function replyToShout({
recipientHandle,
shoutId,
message,
files,
}: ReplyToShoutInput) {
const me = await UserService.getMe();
if (me.numShoutsPastDay >= 5) {
return { error: ErrorMessages.TooManyShouts };
}
const recipient = await UserService.getUser(recipientHandle);
if (!recipient) {
return { error: ErrorMessages.RecipientNotFound };
}
if (recipient.blockedUserIds.includes(me.id)) {
return { error: ErrorMessages.AuthorBlockedByRecipient };
}
try {
let image;
if (files?.length) {
image = await MediaService.saveImage(files[0]);
}
const newShout = await ShoutService.createShout({
message,
imageId: image?.id,
});
await ShoutService.createReply({
shoutId,
replyId: newShout.id,
});
return { error: undefined };
} catch {
return { error: ErrorMessages.UnknownError };
}
}
```
Now this function contains no code related to the UI or React (except for maybe the error messages that could be replaced by some kind of error codes). Even if we migrated to another UI framework we could keep this code without any changes.
_A quick side note: In this series of articles we roughly follow the_ [_Clean Architecture_](https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html)_. In this context, the business logic we extracted is referred to as “application logic” or “use cases” belonging to the “application layer”._
_To keep things clear, we create the file in a new global_ _`application`_ _folder. Later we’ll restructure this project to use a feature-driven folder structure. But for now it’s easier to separate the different layers in their respective folders._
Anyway, let’s continue with the refactoring.
With all this logic isolated in a separate function, the component’s submit handler is much slimmer now.
```typescript
// src/components/shout/reply-dialog.tsx
async function handleSubmit(event: React.FormEvent<ReplyForm>) {
event.preventDefault();
setIsLoading(true);
const message = event.currentTarget.elements.message.value;
const files = Array.from(event.currentTarget.elements.image.files ?? []);
+const result = await replyToShout({
+ recipientHandle,
+ message,
+ files,
+ shoutId,
+});
if (result.error) {
setReplyError(result.error);
}
setOpen(false);
setIsLoading(false);
}
```
Alright, we covered our potential future “let’s migrate to another UI framework” scenario. But testability-wise not much changed. So let’s tackle that.
### Step 2: Custom hook for dependency injection
The `replyToShout` function uses a couple of services to send API requests.
```typescript
// src/application/reply-to-shout.ts
import MediaService from "@/infrastructure/media";
import ShoutService from "@/infrastructure/shout";
import UserService from "@/infrastructure/user";
export async function replyToShout({ ... }) {
const me = await UserService.getMe();
const recipient = await UserService.getUser(recipientHandle);
...
let image;
if (files?.length) {
image = await MediaService.saveImage(files[0]);
}
const newShout = await ShoutService.createShout({ ... });
await ShoutService.createReply({ ... });
}
```
This means it “has dependencies” on these services. That makes testing the `replyToShout` function difficult. We’d have to mock the service modules or the REST API used in the services.
Dependency injection to the rescue.
Dependency injection is a common pattern used to increase testability. Sounds complicated but actually it’s quite simple:
1. We adjust the function to accept a new “dependencies” parameter with the relevant service functions.
2. Then we create a custom hook that “injects” these dependencies.
```typescript
import { useCallback } from "react";
import MediaService from "@/infrastructure/media";
import ShoutService from "@/infrastructure/shout";
import UserService from "@/infrastructure/user";
...
// We create the dependencies as a separate object using the services.
// This way it's already typed and we don't need another TS interface.
const dependencies = {
getMe: UserService.getMe,
getUser: UserService.getUser,
saveImage: MediaService.saveImage,
createShout: ShoutService.createShout,
createReply: ShoutService.createReply,
};
// The replyToShout function accepts the dependencies as second parameter.
// Now the code that calls this function decides what to provide as e.g. getMe.
// This is called inversion of control and helps with unit testing.
export async function replyToShout(
{ recipientHandle, shoutId, message, files }: ReplyToShoutInput,
{ getMe, getUser, saveImage, createReply, createShout }: typeof dependencies
) {
const me = await getMe();
if (me.numShoutsPastDay >= 5) {
return { error: ErrorMessages.TooManyShouts };
}
const recipient = await getUser(recipientHandle);
if (!recipient) {
return { error: ErrorMessages.RecipientNotFound };
}
if (recipient.blockedUserIds.includes(me.id)) {
return { error: ErrorMessages.AuthorBlockedByRecipient };
}
try {
let image;
if (files?.length) {
image = await saveImage(files[0]);
}
const newShout = await createShout({
message,
imageId: image?.id,
});
await createReply({
shoutId,
replyId: newShout.id,
});
return { error: undefined };
} catch {
return { error: ErrorMessages.UnknownError };
}
}
// This hook is just a mechanism to inject the dependencies. A component can
// use this hook without having to care about providing the dependencies.
export function useReplyToShout() {
return useCallback(
(input: ReplyToShoutInput) => replyToShout(input, dependencies),
[]
);
}
```
Note that this file became a bit “dirty”. If we followed the Clean Architecture by the book the application layer shouldn’t contain any references to the UI framework. This file contains code that is specific to the UI framework though (here by exporting a hook and applying `useCallback`). So this file isn’t completely clean. But I think we can be pragmatic here.
Anyway, as we’ll see in a bit it’s now straightforward to test the `replyToShout` function.
> If you think this looks more and more like a typical react-query hook, I agree. In one of the next articles, we’ll introduce react-query into the picture. But for now let’s stay tool-agnostic.
### Step 3: Unit testing the business logic
Since we use dependency injection we can now simply create mock functions and pass those to the `replyToShout` function. We then assert that the correct error is returned or that the service functions received the correct values.
```typescript
import { beforeEach, describe, expect, it, vitest } from "vitest";
import { createMockFile } from "@/test/create-mock-file";
import { ErrorMessages, replyToShout } from "./reply-to-shout";
const recipientHandle = "recipient-handle";
const shoutId = "shout-id";
const message = "Hello, world!";
const files = [createMockFile("image.png")];

expect(mockCreateShout).toHaveBeenCalledWith({
message,
imageId: undefined,
});
expect(mockCreateReply).toHaveBeenCalledWith({
shoutId,
replyId: newShoutId,
});
});
});
```
Now we covered all the edge cases of the `replyToShout` use case with blazing fast unit tests. No need to mock half a dozen different user responses and run through all UI interactions for each of those branches.
With a bit more effort we could even use TypeScript as another layer of safety net. But that would go too far for this time. We’ll cover it in a future article.
Still, let me explain quickly:
Currently we can pass anything we want as mock dependencies. But that can cause a mismatch between the parameters and return types of the real service functions and the mocks. And that again can lead to situations where all our unit tests pass but the application as a whole breaks.
This scenario is usually covered by integration or end-to-end tests. Since these test the features integrated into the larger system a mismatch between mocks and actual implementation quickly becomes evident.
Ok, that’s it for this refactoring. Let me quickly wrap up with a summary of the pros and cons.
[](https://profy.dev/article/react-architecture-business-logic-and-dependency-injection#newsletter-box)
## Advantages and disadvantages of business logic in use cases
We discussed the advantages already. Here a quick summary:
- Isolating business logic from the UI makes it independent of the UI framework.
- Using dependency injection makes it easy to test the logic.
- Removing logic from the components let’s them focus on their responsibility: the UI.
- Plus you finally have a place to put your business logic apart from util functions and custom hooks.
But what about the disadvantages?
To be honest, I don’t see many. But here are a few thoughts:
- There’s a bit of overhead because we created a custom hook for dependency injection.
- This kind of separation is only valuable if you in fact have logic. You don’t need it for a simple API request.
- It might not be that simple to distinguish between different types of logic. At least it took me a while to become better at identifying logic that’s worth being extracted.
- We introduced an architecture that is not very common in React apps so new developers have to get used to it.
Overall the advantages in this case outweigh any potential disadvantages from my perspective.
## Next refactoring steps
This time we talked a lot about business or application logic. Next time, we’ll take a step closer to the core and focus on domain logic.
In fact, we’ve seen this logic mixed with out business logic in the use case function `replyToShout`.
The next step is to move this kind of logic to the domain layer. | jkettmann |

En octobre 2022 je suis placé quatre jours en détention dans une affaire dont je n'ose pas écrire, je suis innocent, c'est un souvenir horrible qui ne fait qu'aggraver mon état mental (dépressif depuis 2019). Je n'oublierais pas les mains tendues de mon ami Mohamed qui m'a encouragé à monter ma société et avec qui nous avons eu de beaux projets, je n'oublie pas mon ami Richard qui m'a proposé un poste d'adjoint en Colombie et je n'oublie pas mon frère Gaétan qui m'a proposé de travailler pour la sélection de la RDC mais aussi bien d'autres choses. Je n'oublierais jamais ces dernières mains tendues, merci infiniment, mais malheureusement c'est trop tard, je suis lessivé, je ne vaux plus rien. Malgré tout, je suis fier aujourd'hui d'être le père de ces trois beaux enfants que j'aime le plus au monde, d'être marié à une femme magnifique que j'aime depuis le premier jour, et de vivre dans cette si belle maison. Mes enfants sont le plus beau cadeau que j'ai eu dans ma vie et sont pour moi les trois plus belles choses au monde, je n'en connais pas d'autre. Laura est tout pour moi, elle a changé ma vie et je lui dois tout, j'espère et je suis certain qu'elle refera sa vie avec quelqu'un de bien, elle le mérite vraiment. Je pense que j'ai eu une belle vie malgré tout, je suis très fier de ce que j'ai fait. Mon nom est déjà inscrit dans 10 stades d'Europe: c'est ma seule volonté et elle est déjà exaucée. À ma mort, je souhaite être baptisé et enterré selon le rite catholique, à Laleu. Si cela n'est pas possible alors, par ordre de préférence Airaines, Abbeville et enfin à l'endroit où je me trouve. Je souhaite que l'on joue le morceau suivant, si possible : Keane - Nothing in my way. Merci Laura, Eric, Isabel, David, Maman, Juliette, Géraldine, Mémé, Pépé, David R, Gaétan, Colin, Marc, Bruno, Mathieu B, Yannick, Thibaut, Madame Ayrault et tous ceux que j'ai pu oublier. Je vous ai toujours aimé.

1,895,939 | How to define and work with a Rust-like result type in NuShell | Motivation Rust—among other modern programming languages—has a data type Result<T,... | 0 | 2024-06-21T11:51:00 | https://dev.to/fkurz/how-to-define-and-work-with-a-rust-like-result-type-in-nushell-51ib | ## Motivation
Rust—among other modern programming languages—has a data type [`Result<T, E>` in its standard library][1], that allows us to represent error states in a program directly in code. Using data structures to represent errors in code is a pattern known mostly from purely functional programming languages but has gained some traction in programming languages that follow a less restrictive language paradigm (like Rust).
The idea of modelling errors in code is that—following the functional credo—everything the function does should be contained in the return value. Side effects, like errors, should be avoided wherever possible.
This is a nice pattern, since it forces you to address that code may not succeed. (If you don't ignore the return value, of course. :D) Combining the use of `Result` return types with [Rust's pattern matching][3] also improves code legibility, in my opinion.
## Error handling in NuShell
[NuShell][5] is a very modern shell and shell language that draws some heavy inspiration from Rust and that I really enjoy writing small programs and glue code in (especially for CI/CD pipelines).
In contrast to Rust, NuShell has a [`try`/`catch`][2] control structure to capture and deal with errors. There is no result type in the [standard library][4] at the time of writing.
NuShell's `try`/`catch`, moreover, has the major downside, that you cannot react to specifics of an error, since the `catch` block doesn't receive any parameter like an exception object, that would allow us introspection on what went wrong.
So what can we do? Well, we may just define a Result type ourselves and use it. Since NuShell also has pattern matching using the `match` keyword, we can write some pretty readable code with it.
Consider, for example, malformed URLs when using the `http` command (in this case the protocol is missing):
```nushell
nu> http get --full www.google.com
Error: nu::shell::unsupported_input
× Unsupported input
╭─[entry #64:1:1]
1 │ http get --full www.google.com
· ────┬─── ───────┬──────
· │ ╰── value: '"www.google.com"'
· ╰── Incomplete or incorrect URL. Expected a full URL, e.g., https://www.example.com
```
The code above will crash. As mentioned before, we could use `try`/`catch`. But the problem remains, how do we enable the calling code to react to errors?
```nu
use std log
try {
return http get --full www.friedrichkurz.me # Missing protocol
} catch {
log error "GET \"https://www.nulldomain.io\" failed."
# Now what?
}
```
Using a result type (and some convenience conversion functions `into ok` and `into error`), we can write a safe http get function as follows:
```nu
def safe_get [url: string] {
try {
let response = http get --full $url
$response | into ok
} catch {
{url: $url} | into error
}
}
```
We could use it in our code like this:
```nu
nu> match (safe_get "https://www.google.com") {
{ok: $response} => { print $"request succeeded: ($response.status)" },
{error: $_} => { print "request failed" }
}
request succeeded: 200
```
And for the failure case:
```nu
match (safe_get "www.google.com") {
{ok: $response} => { print $"request succeeded: ($response.status)" },
{error: $_} => { print "request failed" }
}
request failed
```
Now the calling code can react to failure by disambiguating the return values and processing the attached data.
## Addendum
Here are the helper functions `into ok` and `into error` for completeness sake.
```nu
export def "into ok" [value?: any] {
let v = if $value == null { $in } else { $value }
{ok: $v}
}
export def "into error" [cause?: any] {
let c = if $cause == null { $in } else { $cause }
{error: $c}
}
```

One of the most powerful features of the JavaScript language is the ability to handle asynchronous operations. Asynchronous programming allows developers to perform tasks like fetching data from a server or reading a file without blocking the main execution thread. This ensures that applications remain responsive and efficient, providing a smoother user experience and better performance.
## Basics of Asynchronous Programming
In programming, operations can be either synchronous or asynchronous. Understanding the difference between these two types is crucial for effective programming.
## Synchronous Programming
Synchronous programming blocks the execution of subsequent code until the current operation completes. This means that each task is performed one after the other, waiting for the previous one to finish.
Consider a scenario where you need to book a flight, reserve a hotel room, and rent a car for a trip. In a synchronous world, you would call each service one by one, waiting on hold until each booking is confirmed before moving to the next. This approach can be problematic in certain situations, particularly when dealing with tasks that take a significant amount of time to complete.
A good example is when a synchronous program performs a task that requires waiting for a response from a remote server. The program will be stuck waiting for the response and cannot do anything else until the response is returned. This is known as blocking, and it can lead to the application appearing unresponsive or “frozen” to the user.
## Asynchronous Programming
In contrast, asynchronous programming allows the execution of subsequent code to proceed independently while waiting for the current operation to complete.
Using the same scenario where you need to book a flight, reserve a hotel room, and rent a car for a trip, in an asynchronous world, you could call all three services simultaneously. While waiting for each service to confirm your booking, you can continue with other trip preparations, making the overall process faster and more efficient.
Asynchronous programming allows a program to continue working on other tasks while waiting for external events, such as network requests, to occur. For example, while a program retrieves data from a remote server, it can continue to execute other tasks such as responding to user inputs. This greatly improves the performance and responsiveness of a program.
## Handling Asynchronous Operations
In JavaScript, asynchronous programming can be achieved through a variety of techniques. In this article, we are going to cover ways in which you can do this.
## Using Callbacks
Callbacks are one of the oldest and most widely used methods for handling asynchronous operations in JavaScript. A callback function is simply a function that is passed as an argument to another function and is executed after the completion of a task.
```javascript
// Declare function
function fetchData(callback) {
setTimeout(() => {
const data = {name: "John", age: 24};
callback(data);
}, 3000);
}
// Execute function with a callback
fetchData(function(data) {
console.log(data);
});
console.log("Data is being fetched...");
```
In this example:
- We declare a function named fetchData that takes a callback function as an argument.
- Inside fetchData, the setTimeout function is used to simulate an asynchronous operation by delaying the execution of a callback function for 3 seconds.
- After the 3-second delay, the callback function passed to fetchData is invoked with a mock data object as its argument.
- The callback function passed to fetchData is an anonymous function that logs the received data object to the console.
- Output: Initially, a message “Data is being fetched…” is logged to the console. After 3 seconds, the mock data object is fetched, and the callback function is executed, logging the data object to the console.
Callbacks are powerful because they allow us to continue with other tasks while waiting for asynchronous operations to complete. However, they can lead to callback hell, a situation where multiple nested callbacks make the code difficult to read and maintain.
```javascript
getData(function(data1) {
processData1(data1, function(data2) {
processData2(data2, function(data3) {
processData3(data3, function(data4) {
// and so on...
});
});
});
});
```
In this example, each asynchronous operation depends on the result of the previous one, leading to deeply nested callbacks. As more operations are added, the code becomes increasingly difficult to manage, often resulting in bugs and decreased readability.
Despite their drawbacks, callbacks are still widely used, especially in older codebases and libraries. Understanding how to use callbacks effectively is essential for any JavaScript developer.
## Using Promises
Promises provide a more elegant way to handle asynchronous operations compared to callbacks. A Promise represents a value that may be available now, in the future, or never. Promises have three states: Pending, Fulfilled, and Rejected.
```javascript
function fetchData() {
return new Promise((resolve, reject) => {
setTimeout(() => {
const data = {name: "John", age: 24};
resolve(data);
}, 3000);
});
}
fetchData().then(console.log).catch(console.error);
```
In this example, the fetchData function returns a Promise. Inside the Promise constructor, an asynchronous operation is simulated using setTimeout. Once the operation is complete, the resolve function is called with the fetched data.
Promises allow for chaining using the then method, making it easy to perform sequential asynchronous operations. Additionally, error handling is simplified with the catch method, which handles any errors that occur during the execution of the Promise chain.
## Async/Await: Simplifying Asynchronous Code
Async/Await is a powerful feature in JavaScript that simplifies asynchronous programming by providing a more synchronous-looking syntax. While it builds on top of Promises, it offers a more intuitive way to handle asynchronous operations without directly dealing with Promise chains.
```javascript
function fetchData() {
return new Promise((resolve, reject) => {
setTimeout(() => {
const data = {name: "John", age: 24};
resolve(data);
}, 3000);
});
}
async function getData() {
try {
const data = await fetchData();
console.log(data);
} catch (error) {
console.error(error);
}
}
getData();
```
Here, the fetchData function returns a Promise, as it did before. However, instead of chaining .then() and .catch() methods, the getData function is defined as an async function. Inside getData, the await keyword is used to pause the execution until the fetchData Promise resolves, making the asynchronous code flow appear synchronous.
Using Async/Await simplifies error handling with traditional try/catch blocks, providing a more natural way to handle errors in asynchronous code. Overall, Async/Await makes asynchronous programming in JavaScript more readable and maintainable by allowing developers to write asynchronous code that looks and behaves like synchronous code.
## Practical Applications of Asynchronous JavaScript
Asynchronous JavaScript is essential for creating responsive and efficient applications. Here are some practical applications where asynchronous operations play a crucial role:
## 1.Fetching Data from APIs
Applications often need to retrieve data from external APIs. Asynchronous operations allow the application to continue running while waiting for the data to be fetched.
```javascript
async function fetchUserData() {
try {
const response = await fetch('https://api.example.com/user');
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error fetching user data:', error);
}
}
fetchUserData();
```
In this example, the fetch API is used to retrieve user data. The await keyword ensures the code waits for the response before proceeding, without blocking the main thread.
## 2.File Operations
When working with files, such as reading or writing to the file system, asynchronous operations are essential to prevent the main thread from freezing.
```javascript
const fs = require('fs');
fs.readFile('file.txt', 'utf8', (err, data) => {
if (err) {
console.error('Error reading file:', err);
return;
}
console.log('File contents:', data);
});
console.log('This message will be printed first');
```
In this example, when fs.readFile() is called, Node.js initiates the file read operation but doesn't wait for it to complete. Instead, it registers the provided callback function and immediately continues executing the next line, which logs the message 'This message will be printed first'. When the file read operation completes, Node.js places the callback function in the event queue, and the event loop eventually dequeues and executes it on the main thread, logging the file contents or an error message.
By using asynchronous programming for file operations, the main execution thread remains responsive and can handle other tasks while waiting for the file operation to complete.
## 3.Timers
JavaScript provides the setTimeout and setInterval functions for scheduling code execution after a specified delay or at regular intervals, respectively. These functions are asynchronous, meaning they don't block the main execution thread while waiting for the specified time to elapse.
```javascript
// Scheduling a recurring execution every second
const intervalId = setInterval(() => {
console.log('This message will be displayed every second');
}, 1000);
// After 5 seconds, stop the recurring execution
setTimeout(() => {
clearInterval(intervalId);
console.log('Interval cleared');
}, 5000);
```
In this example, we store the identifier returned by setInterval in the intervalId variable. After 5 seconds (using setTimeout), we call clearInterval(intervalId), which stops the recurring execution scheduled by setInterval.
The clearInterval function is useful when you want to stop a recurring task based on certain conditions, such as user interactions, state changes, or timers. Without clearInterval, the recurring execution would continue indefinitely unless the page is reloaded or the script is terminated.
## 4.Animations
Creating smooth animations is another important use case for asynchronous JavaScript. The requestAnimationFrame function is designed specifically for this purpose. It tells the browser to update an animation before the next repaint, ensuring optimal performance and efficient use of system resources.
```javascript
const element = document.getElementById('myElement');
let position = 0;
function animateElement() {
position += 10; // Update the position
element.style.left = `${position}px`; // Move the element
// Request the next animation frame
if (position < 500) {
requestAnimationFrame(animateElement);
}
}
// Start the animation
requestAnimationFrame(animateElement);
```
In this example, the animateElement function is recursively called using requestAnimationFrame until the desired position is reached. The browser handles these function calls asynchronously, ensuring that the animation runs smoothly without blocking the main execution thread, ensuring a seamless user experience in web applications.
## 5.Event Handling
Event handling in the browser is inherently asynchronous, as events are triggered by user interactions or other external factors.
```javascript
const button = document.getElementById('myButton');
button.addEventListener('click', () => {
console.log('Button clicked!');
});
console.log('This message will be displayed first');
```
In this example, when the script runs, it logs the message 'This message will be displayed first' to the console immediately. However, the event handler function (() => { console.log('Button clicked!'); }) is not executed until the user actually clicks the button.
When the user clicks the button, the browser generates a click event and adds it to the event queue. The event loop detects the event in the queue and executes the registered event handler function, which logs the message 'Button clicked!' to the console.
This asynchronous nature of event handling ensures that the JavaScript code doesn’t block the main execution thread while waiting for user interactions or other external events. The browser can continue to update the UI, parse HTML, execute other scripts, and perform other tasks while waiting for events to occur.
## Conclusion
The practical applications discussed are indeed among the most important and widely-used cases where asynchronous JavaScript is employed. However, these examples do not represent an exhaustive list.
It is crucial to recognize that asynchronous programming is a widespread concept that finds applications in numerous other scenarios within the constantly evolving field of web development and beyond. As new technologies and use cases emerge, the significance of asynchronous programming in JavaScript is likely to continue increasing, ensuring efficient, responsive, and scalable applications across various domains.

## Introdução
Se você está desenvolvendo uma aplicação que visa um público global, ou simplesmente deseja oferecer suporte a múltiplos idiomas, um seletor de idioma é essencial.
A alternância entre idiomas é importante pois oferece uma experiencia melhor para o usuário, permitindo que ele escolha um idioma de sua preferência de maneira rápida e fácil.
Neste artigo, você vai aprender de maneira rápida como fazer sua aplicação ter suporte a diferentes idiomas.
Lembrando que neste artigo faremos a alternância entre 2 idiomas, mas a partir disso você pode fazer com quantos idiomas desejar. Então, mão na massa!
## Passo a passo
### Passo 1: Criando nosso projeto Flutter
Para criar nosso projeto Flutter, vamos simplesmente rodar o seguinte comando
```bash
flutter create internationalization_example
```
Aqui batizamos o nome do nosso projeto como "internationalization_example". Você pode colocar o nome que preferir.
### Passo 2: Adicionando flutter_localizations, intl e provider
Agora, vamos adicionar os packages que precisamos para o nosso toggle de idiomas. Para isso, dentro do nosso projeto flutter vamos rodar os seguintes comandos:
- Adicionando **flutter_localizations**: Este pacote será para adicionar suporte a outros idiomas já que por padrão o Flutter suporta somente o Inglês.
```bash
flutter pub add flutter_localization
```
- Adicionando o **intl**: Este pacote oferece recursos de internacionalização e localização, incluindo tradução de mensagens, plurais e gêneros, formatação e análise de data/número e texto bidirecional.
```bash
flutter pub add intl:any
```
- Adicionando o **provider**: Utilizaremos este para injeção de dependência que vamos precisar mais pra frente.
```bash
flutter pub add provider
```
⚠️ **Agora uma pequena alteração:**
No nosso arquivo `pubspec.yaml`, precisaremos alterar a forma de declaração do nosso **flutter_localization** como mostrado abaixo e após isso dar um `ctrl + s` para reinstalar as nossas dependências:
```diff
dependencies:
flutter:
sdk: flutter
+ flutter_localizations:
+ sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^1.0.6
- flutter_localization: ^0.2.0
intl: any
provider: ^6.1.2
```
### Passo 3: Gerando arquivos de tradução
Dentro da pasta `lib` vamos criar uma pasta chamada `l10n` e dentro criar um arquivo chamado `app_en.arb` para os textos em inglês (**en** é a sigla da linguagem desejada, você pode colocar a sigla da linguagem que quiser) e um chamado `app_pt.arb` para textos em português.
Vamos escrever nossas traduções da seguinte forma:
```dart
// app_en.arb
{
"helloWorld": "Hello World!",
"counterMsg": "You have pushed the button this many times:"
}
```
```dart
// app_pt.arb
{
"helloWorld": "Olá mundo",
"counterMsg": "Você apertou o botão essa quantidade de vezes:"
}
```
> Lembrando que as chaves das traduções devem ser **exatamente** iguais nos dois arquivos.
Você deverá fazer isso para todos os textos que deseja traduzir na sua aplicação. "Ah mas eu tenho um montão de textos nela!". Então... boa sorte. 👍
_**Curiosidade**: A sigla **l10n** é assim porque na palavra **localization** tem 10 letras entre a letra L e a letra N._
Criados os nossos arquivos, para ativar a nossa geração dos arquivos de tradução, vamos no nosso arquivo `pubspec.yaml` novamente e habilitar a flag `generate` como no exemplo abaixo:
```yaml
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
generate: true
```
Agora, para gerar nossos arquivos, rodamos o seguinte comando:
```bash
flutter gen-l10n
```
Estes arquivos gerados ficarão localizados em `dart_tool/flutter_gen/gen_l10n.`
> _**Não mexa nesses arquivos.** Toda alteração nas traduções deve ser feita **somente** nos arquivos .arb_
### Passo 4: Configurando as linguagens na nossa aplicação
Agora configuraremos nosso `MyApp`, afinal, é a partir dele que a mágica acontece.
>O **MyApp** é onde fica o nosso **MaterialApp** que nada mais é que a **raiz de um aplicativo Flutter**, que fornece uma estrutura base para navegação, estilização e internacionalização.
Dito isso, vamos adicionar as nossas configurações de internacionalização:
```dart
import 'package:flutter/material.dart';
import 'package:flutter_gen/gen_l10n/app_localizations.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:internationalization_flutter_example/app/my_home_page.dart';
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
useMaterial3: true,
),
// Delegações de internacionalização globais
localizationsDelegates: const [
AppLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
// linguagens que nossa aplicação irá suportar
supportedLocales: const [
Locale('en'),
Locale('pt'),
],
// idioma atual da nossa aplicação
locale: const Locale('pt'),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
```
### Passo 5: Adicionando traduções na nossa aplicação
Para adicionar as traduções nas páginas da nossa aplicação, vamos substituir os textos presentes na aplicação pelas chaves correspondentes do arquivo gerado com o comando `flutter gen-l10n` como no exemplo abaixo:
```dart
import 'package:flutter_gen/gen_l10n/app_localizations.dart';
...
appBar: AppBar(
// adicionando texto da chave helloWorld
title: Text(AppLocalizations.of(context)!.helloWorld),
),
```
> **Nota:** a cada mudança nos arquivos .arb é necessário rodar novamente o comando `flutter gen-l10n` para que as mudanças persistam nos arquivos de tradução gerados.
### Passo 6: Fazendo toggle de idiomas
Agora, por fim, vamos fazer nosso toggle de idiomas!! Para isso vamos criar uma controller que vai estender de `ChangeNotifier` (vamos usar o `ChangeNotifier` para que a nossa tela fique escutando qualquer alteração na nossa classe)
Nesta classe vamos criar uma variável booleana (vou chamá-la de `isEnglish`) que recebe por padrão `true`
Criada a variável, criaremos agora uma função `void` que toda vez que for chamada o valor da variável mudará para sua negação (isso significa que se ela for true se tornará false e vice-versa) e logo após notificamos essa alteração usando `notifyListeners();`.
Nossa controller ficará da seguinte forma:
```dart
import 'package:flutter/material.dart';
class LanguageController extends ChangeNotifier {
bool isEnglish = true;
void toggleLanguage() {
isEnglish = !isEnglish;
notifyListeners();
}
}
```
Agora voltando ao nosso `MyApp`, vamos injetar o nosso controller que é a nossa dependência:
```dart
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
// adicionamos o ChangeNotifierProvider para fornecer o LanguageController
return ChangeNotifierProvider(
// criamos uma instância de LanguageController
create: (context) => LanguageController(),
builder: (context, child) {
// acessamos o LanguageController por meio do Provider
final languageController = Provider.of<LanguageController>(context);
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
useMaterial3: true,
),
localizationsDelegates: const [
AppLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
supportedLocales: const [
Locale('en'),
Locale('pt'),
],
// acessamos o atributo isEnglish do LanguageController para definir o idioma
// se false, o idioma será português (pt), caso contrário, será inglês (en)
locale: languageController.isEnglish ? const Locale('en') : const Locale('pt'),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
},
);
}
}
```
> O `ChangeNotifierProvider` é uma classe do pacote `provider` no Flutter, que é usado para fornecer uma instância de um `ChangeNotifier` aos widgets descendentes na árvore de widgets. Sendo assim, o método `create` é chamado para criar uma instância de `LanguageController` para que possamos acessar os dados ou regras de negócio presentes nele.
Agora, na nossa tela, vamos adicionar o nosso botão para mudar o idioma da nossa aplicação:
```dart
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});
final String title;
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
// acessamos o LanguageController por meio do Provider
final languageController = Provider.of<LanguageController>(context);
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text(AppLocalizations.of(context)!.helloWorld),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
AppLocalizations.of(context)!.counterMsg,
),
Text(
'2',
style: Theme.of(context).textTheme.headlineMedium,
),
],
),
),
floatingActionButton: FloatingActionButton(
// chamando nossa função do LanguageController
onPressed: languageController.toggleLanguage,
tooltip: 'Toggle Language',
child: const Icon(Icons.language),
),
);
}
}
```
Ao fim disso, nosso toggle de idiomas já está funcionando, basta clicar no botão flutuante e o idioma da nossa aplicação mudará assim como demonstrado abaixo:

1,895,934 | Bitwise operators in Java: unpacking ambiguities | Author: Kirill Epifanov The "&" and "|" operators are pretty straightforward and unambiguous... | 0 | 2024-06-21T11:27:13 | https://dev.to/anogneva/bitwise-operators-in-java-unpacking-ambiguities-3783 | java, programming, coding | Author: Kirill Epifanov
The "&" and "\|" operators are pretty straightforward and unambiguous when applied correctly\. But do you know all the implications of using bitwise operators instead of logical ones in Java? In this article, we will examine both the pros of this approach in terms of performance and the cons in terms of code readability\.
## Before we start
This is the third and the final article of the series\. It's written based on the results of checking [DBeaver](https://github.com/dbeaver/dbeaver) version 24 with the help of the PVS\-Studio static analyzer\. The tool detected a few suspicious code fragments that caught our development team's attention and prompted us to cover them in several articles\. If you haven't read the previous ones, you can find them here:
* [Volatile, DCL, and synchronization pitfalls in Java](https://pvs-studio.com/en/blog/posts/java/1128/)
* [How template method can ruin your Java code](https://pvs-studio.com/en/blog/posts/java/1132/)
* Bitwise operators in Java: unpacking the ambiguities \(you are here\)
## Once upon a time
While wading through the warnings issued by the analyzer, we encountered a warning for logical expressions that contained bitwise operations in an *if* block\. The analyzer claims it to be a suspicious code snippet and issues a warning of the second \(medium\) level — [V6030](https://pvs-studio.com/en/docs/warnings/v6030/)\. Here are some of the PVS\-Studio messages:
The [ExasolSecurityPolicy\.java\(123\)](https://github.com/dbeaver/dbeaver/blob/f0c87ca1251621e3803a9a807dd4336bfdfef0c1/plugins/org.jkiss.dbeaver.ext.exasol/src/org/jkiss/dbeaver/ext/exasol/model/security/ExasolSecurityPolicy.java#L123) file\.
```cpp
public ExasolSecurityPolicy(....) {
....
String value = JDBCUtils.safeGetString(dbResult, "SYSTEM_VALUE");
if (value.isEmpty() | value.equals("OFF"))
this.enabled = false;
} else {
assignValues(ExasolSecurityPolicy.parseInput(value));
}
}
```
The analyzer reports that the *value\.equals\("OFF"\)* method is called even if *value\.isEmpty\(\)* is true, which is meaningless\. The warning:
[V6030](https://pvs-studio.com/en/docs/warnings/v6030/) The method located to the right of the '\|' operator will be called regardless of the value of the left operand\. Perhaps, it is better to use '\|\|'\.
The [ExasolConnectionManager\.java\(151\)](https://github.com/dbeaver/dbeaver/blob/f0c87ca1251621e3803a9a807dd4336bfdfef0c1/plugins/org.jkiss.dbeaver.ext.exasol/src/org/jkiss/dbeaver/ext/exasol/manager/ExasolConnectionManager.java#L151) file\.
```cpp
@Override
protected void addObjectModifyActions(....) {
....
// url, username or password have changed
if (com.containsKey("url") | com.containsKey("userName") |
com.containsKey("password"))
{
// possible loss of information - warn
....
if (!(con.getUserName().isEmpty() | con.getPassword().isEmpty())) {
....
}
}
}
```
Here we see sequential checks of Map *com* for *url* keys, *userName*, or *password*\. Then, the absence of one of the connection parameters is checked similarly\. As a result, we receive the same old message yet again:
[V6030](https://pvs-studio.com/en/docs/warnings/v6030/) The method located to the right of the '\|' operator will be called regardless of the value of the left operand\. Perhaps, it is better to use '\|\|'\.
The documentation of the PVS\-Studio analyzer states that the function returning a *boolean* value is located to the right of the bitwise operator, which is probably a typo\. I got curious about this code style\. After all, if there was a single warning of this kind, I'd think it was a typo\. However, the project shows 16 such code fragments, and I wondered if there's a double dip in such an error pattern\.
## Operators and how do they differ
Let's take a quick dive into the theory\. I think it's reasonable to skip the long list of Java operators and focus directly on the bitwise and logical ones we need:
* && — logical AND
* \|\| — logical OR
* & — bitwise AND
* \| — bitwise OR
Every theoretical Java website states that bitwise operations, unlike logical ones, always execute both parts of an expression\. This code is an example of using the bitwise operator:
```cpp
public static void main(String[] args) {
// updateA() and updateB() is always executed
if (updateA() & updateB()) {
// Doing something
}
}
public boolean updateA() {
// Changing the state...
return ....;
}
public boolean updateB() {
// Changing the state...
return ....;
}
```
If we replace the bitwise operator with the logical one and the first condition returns *false*, the execution of the checks stops\. Let's get a bit imaginative and explore examples that alter the inner state\. In the following code, if *prepareConnection\(\)* returns *false*, the *establishConnection\(\)* method isn't executed\.
```cpp
public static void main(String[] args) {
// establishConnection() is executed only if prepareConnection() -> false
if (prepareConnection() && establishConnection()) {
....
}
}
public boolean prepareConnection() {
....
}
public boolean establishConnection() {
....
}
```
So, if the operator can determine the result of the operation based on the evaluation of the left argument alone, the second argument is not evaluated as it's deemed unnecessary\. This mechanism is called **short\-circuit evaluation**\. Perhaps one of the most popular use cases for short circuits is to check for *null* before using a variable\.
```cpp
public boolean testString(String str) {
return str != null && str.equals("test");
}
```
At this point, it may seem that the DBeaver developers made a mistake that increased the number of checks done in the *if* blocks\. This could have been due to a typo or just plain unawareness\. But that's where the **ambiguity** comes into play\.
## The far it goes\.\.\.
Let's dig into the details\. It turns out that a bitwise operation can be faster than a logical operation, depending on the context\. This is mainly because bitwise operators don't involve a **branch prediction** mechanism\.
> Branch prediction is a unit included in the CPU\. It enables prefetching of branch instructions as well as execution of instructions placed after a branch \(e\.g\., an *if* block\) before it is executed\. The branch predictor is an integral part of all modern pipelined processors\. It enables the optimization of computing resources\.
As a side note, I should mention that branch prediction is closely related to **speculative execution**\. In short, it enables the processor to perform some operations on a stream of data ahead of time without waiting until it determines whether data is taken or not\. If lucky and data is taken, we get a performance boost\. If not, the changes are rolled back, incurring overhead\.
So, modern processors have instruction pipelining\. Each executed instruction has several stages: fetch, decode, execute, and save\.
* The fetch stage: the processor retrieves the instruction from memory\.
* The decode stage: the processor interprets the instruction\.
* The execute stage: the processor executes the operation specified by the instruction\.
* The save stage: the processor saves the result of the execution\.
Within a processor, different operations can be executed in parallel: one instruction is being executed while another is being fetched from memory\. The table below can illustrate this:
Everything seems fine until we encounter a branch instruction along the way\. And that's where our pipelined processor is going to hit a snag\. If a conditional operator appears in the middle of the pipeline execution, the processor can't fetch the next operations because they depend on the outcome of the logical block\.
That's why modern processors try to **predict the execution flow** and anticipate the instructions to be executed next\. It optimizes code execution if it's not explicitly specified\. For example:
```cpp
private boolean debug = false;
public void test(....) {
....
if (debug) {
log("....");
}
....
}
```
In this case, the processor \(though the compiler and JVM can also make adjustments, which we'll ignore for now\) can predict with high probability that the *log* method call won't occur\. So, the processor won't prepare to execute this code based on execution statistics\. However, if the processor makes an error, the pipeline needs to be rebuilt, which **may impact performance**\.
Bitwise operations lack this mechanism: **they do not involve branches** and are devoid of their overhead\.
To confirm this, I ran a tiny benchmark based on the source code provided by a developer known as [Rostor](https://stackoverflow.com/users/166235/rotsor) \([source](https://stackoverflow.com/questions/3076078/check-if-at-least-two-out-of-three-booleans-are-true/)\)\.
<spoiler title="Code">
[Uploaded](https://gist.github.com/TheLivan/9f301c4ded3a1d95807c18e9da35bbe1) to GitHub Gist
Here we call methods with logical expressions one by one, using both bitwise and logical operations\.
</spoiler>
The research results on my PC surprised me\. In an average test without using functional interfaces and other OOP tricks, bitwise operations appear to be up to 40 percent faster than logical ones\. You may read the chart below displaying the time taken for each individual operation\.
The test compares conjunctions and disjunctions, both separately and all together\. The biggest ones are shown at the top for quick reference\. One immediate conclusion is apparent: logical operators turn out to be slower in this case\.
Why? Branch prediction can often be erroneous and cause performance issues\. In such a case, the bitwise operator clearly gains in execution performance due to the absence of this mechanism\.
However, it's worth mentioning that this test is not flawless, and outcomes can still vary based on the processor design, performance, and testing conditions, which we'll delve into shortly\. I'd love to discuss the test results and hear your thoughts on them in the comments\. Nevertheless, it now seems that bitwise operators can run faster\.
## Why, exactly, is that bad?
After reading all this, you might wonder, "Why does this diagnostic exist in your analyzer if such code can be executed faster? Even if a programmer makes a typo, isn't it just a [code smell](https://en.wikipedia.org/wiki/Code_smell)?"
I'm still against such code, and here's why:
**First**, let me show you two interesting warnings from the same project that were among several other "false positives"\.
The [ExasolTableColumnManager\.java\(79\)](https://github.com/dbeaver/dbeaver/blob/2102cbe2629742e2b8e3bd054a92e81b111ea9a4/plugins/org.jkiss.dbeaver.ext.exasol/src/org/jkiss/dbeaver/ext/exasol/manager/ExasolTableColumnManager.java#L79) and [DB2TableColumnManager\.java\(77\)](https://github.com/dbeaver/dbeaver/blob/f0c87ca1251621e3803a9a807dd4336bfdfef0c1/plugins/org.jkiss.dbeaver.ext.db2/src/org/jkiss/dbeaver/ext/db2/manager/DB2TableColumnManager.java#L77) files\.
```cpp
@Override
public boolean canEditObject(ExasolTableColumn object) {
ExasolTableBase exasolTableBase = object.getParentObject();
if (exasolTableBase != null &
exasolTableBase.getClass().equals(ExasolTable.class)) {
return true;
} else {
return false;
}
}
```
[V6030](https://pvs-studio.com/en/docs/warnings/v6030/) The method located to the right of the '&' operator will be called regardless of the value of the left operand\. Perhaps, it is better to use '&&'\.
This practice sets the stage for** an error and a *NullPointerException***\.
In this case, it's worth considering the side effects and being careful\. Sometimes it's easy to overlook the fact that you're writing code incorrectly\. In the above case, if the *exasolTableBase* parameter turns out to be *null*, an exception is thrown\. And honestly, I don't think the developer meant for the program to crash over a simple check for editability :\)
Besides, one of the developers copied the erroneous code and pulled it into another program module\. Let's add copy\-pasting to the list of sins\. That's why there are two erroneous files above\.
**Second**, another drawback is that we **lose short\-circuit evaluation**, which often improves the performance of the operation\.
For example, as in this case, for which the analyzer also issued a warning:
The [ExasolDataSource\.java\(950\)](https://github.com/dbeaver/dbeaver/blob/7b0fb97265d183cfd5ec2a9524583caa8e76abdb/plugins/org.jkiss.dbeaver.ext.exasol/src/org/jkiss/dbeaver/ext/exasol/model/ExasolDataSource.java#L952) file\.
```cpp
@Override
public ErrorType discoverErrorType(@NotNull Throwable error) {
String errorMessage = error.getMessage();
if (errorMessage.contains("Feature not supported")) {
return ErrorType.FEATURE_UNSUPPORTED;
} else if (errorMessage.contains("insufficient privileges")) {
return ErrorType.PERMISSION_DENIED;
} else if (
errorMessage.contains("Connection lost") |
errorMessage.contains("Connection was killed") |
errorMessage.contains("Process does not exist") |
errorMessage.contains("Successfully reconnected") |
errorMessage.contains("Statement handle not found") |
....
)
{
return ErrorType.CONNECTION_LOST;
}
return super.discoverErrorType(error);
}
```
[V6030](https://pvs-studio.com/en/docs/warnings/v6030/) The method located to the right of the '\|' operator will be called regardless of the value of the left operand\. Perhaps, it is better to use '\|\|'\.
In this method, the developer checks the *errorMessage* string and returns the error type\. Everything seems fine, but when using a bitwise operator in an *else if* statement, we lose the short\-circuit evaluation optimization\. This is obviously a bad thing, because if any substring is found, we could jump straight to *return* instead of checking the other options\.
**Third**, there's no guarantee bitwise operations will be faster for you\. And if it will, that's just a **micro\-optimization** of a few nanoseconds\.
**Fourth**, the synthetic test above succeeded because the provided values exhibit a **normal distribution** and show no apparent patterns\. In the test, branch prediction only makes it worse\.
So, if the branch predictor operates correctly, bitwise operations cannot catch up with the performance of logical operations\. This case is **very** **specific**\.
To sum up all of the above, the **final** drawback is that constant bitwise checks may seem unconventional from a **code\-writing style** perspective\. Especially when the code involves actual bitwise operations\. It's easy to picture the reaction of a modern Java programmer who encounters a bitwise operator in an *if* statement during code review\.

## Conclusion
That's all for today\. I have investigated the relevance of replacing logical operators with bitwise operators, as well as the applicability of the analyzer's diagnostic rule\. And you've gained some insights into our favorite Java and its practices =\)

In today's blog post you will learn how to map objects in .NET using various techniques and libraries.
We'll explore what is the best way to map objects in .NET in 2024.

## What is Object Mapping
What is **object mapping** and why do you need one in ASP.NET Core applications?
**Object mapping** is a transformation of objects from one type to another, often between different layers of an application.
Mapping is essential for separation of concerns
Here are a few reasons to use object mapping:
* **Separation of concerns:** keeps business logic and data transfer logic distinct.
* **Performance:** decreases size of objects transferred through the network, sending only the necessary piece of data needed by clients.
* **Security:** hides private domain data from the clients. Like real entity ids, personal data, and internal domain properties.
* **Maintainability:** simplifies updates and changes to the data structures, as domain models are distinguished from the public contract used by clients.
In many applications, usually there are 2 levels of models: domain and public contracts.
These public contract models are often called DTOs (data transfer objects).
DTOs are the models consumed by a client, and usually they are tinier than their domain counterparts.
Also, a DTO model may contain properties from few domain models.
It is essential to distinguish domain internal models from the public models.
Clients should receive the exact piece of data they need, no more.
And they shouldn't consume models that contain private and internal data due to security considerations.
Another reason for using separate models for public contracts: you can change your domain models while keeping your public contracts unchanged, so you won't break the clients using the API.
## How To Do Object Mapping
We figured out what object mapping is, now let's explore some of the most used mapping techniques.
There are 2 main approaches of object mapping: **manual** and **automated** by using mapping libraries.
Manual approach involves manually writing code that performs mapping, for example:
```csharp
public static BookDto MapToBookDto(this Book entity)
{
return new BookDto
{
Title = entity.Title,
Year = entity.Year,
Isbn = entity.Isbn,
Price = entity.Price
};
}
var bookDto = book.MapToBookDto();
```
When mapping properties of `Book` domain entity to `BookDto` we need to manually set all properties of the DTO model.
This if often tiresome, that's why a mapping libraries were created.
These libraries automate the process of mapping and reduce the boilerplate code.
On paper, these libraries should minimize the risk of errors, but the reality is the opposite.
To showcase why using mapping libraries is not the best option in 2024, first we need to have a look at these libraries and how they perform object mapping.
## Mapping Using AutoMapper Library
**AutoMapper** is one of the most popular libraries for object-to-object mapping in .NET.
To add AutoMapper to your project, you need to run the following command to install NuGet package:
```bash
dotnet add package AutoMapper
```
Let's create a mapping from `Book` entity to `BookDto`:
```csharp
public class Book
{
public Guid Id { get; set; }
public string Title { get; set; }
public int Year { get; set; }
public string Isbn { get; set; }
public decimal Price { get; set; }
public Author Author { get; set; }
}
public record BookDto
{
public string Isbn { get; set; }
public string Title { get; init; }
public int Year { get; init; }
public decimal Price { get; set; }
public string Author { get; set; }
}
```
First, you need to configure AutoMapper how to map these objects.
You need to create a mapping class that inherits from base `Profile` class.
In this mapping profile, you need to specify only those fields that differ between the models.
Other properties are mapped automatically.
```csharp
public class BookProfile : Profile
{
public BookProfile()
{
CreateMap<Book, BookDto>()
.ForMember(dest => dest.Author, opt => opt.MapFrom(src => src.Author.Name));
CreateMap<BookDto, Book>()
.ForPath(dest => dest.Author.Name, opt => opt.MapFrom(src => src.Author));
}
}
```
`BookDto` is very similar to the `Book` entity, but has no `Id` property and has `Author` name as string that is mapped to the child `Author` entity.
Next, you need to register AutoMapper and its profiles in the DI container.
```csharp
builder.Services.AddAutoMapper(typeof(Program));
```
In the `AddAutoMapper` method you need to specify types of assemblies that contain the mapping profiles.
Finally, to use mapping, you need to use the `IMapper` interface and call the `Map` method:
```csharp
public class SomeService
{
private readonly IMapper _mapper;
public SomeService(IMapper mapper)
{
_mapper = mapper;
}
public BookDto ToBookDto(Book entity)
{
return _mapper.Map<BookDto>(entity);
}
}
```
## Mapping Using Mapster Library
**Mapster** is another powerful library for object mapping in .NET, known for its high performance and flexibility.
This library is newer and faster when compared to AutoMapper.
To install Mapster, use the NuGet package manager:
```bash
dotnet add package Mapster.DependencyInjection
```
Mapster setup is much similar to the AutoMapper.
First, create a profile by inheriting from the `IRegister` interface:
```csharp
public class BookProfile : IRegister
{
public void Register(TypeAdapterConfig config)
{
config
.NewConfig<Book, BookDto>()
.TwoWays()
.Map(dest => dest.Author, src => src.Author.Name);
}
}
```
Then register Mapster in DI and add all the mapping profiles:
```csharp
builder.Services.AddMapster();
TypeAdapterConfig.GlobalSettings.Scan(Assembly.GetExecutingAssembly());
```
To use Mapster, inject the same `IMapper` interface, but from another namespace:
```csharp
public class SomeService
{
private readonly IMapper _mapper;
public SomeService(IMapper mapper)
{
_mapper = mapper;
}
public BookDto ToBookDto(Book entity)
{
return _mapper.Map<BookDto>(entity);
}
}
```
Mapster also supports a static extension method `Adapt`, available for any object.
This method performs an automatic mapping that doesn't require any mapping configuration:
```csharp
var bookDto = bookEntity.Adapt<BookDto>();
```
You can use this method for simple mappings where two models differ slightly.
So mapping libraries seem to be a great option, but why this is not the best approach to do the object mapping?
Let's find out!
## Why Using Mapping Libraries is Not a Silver Bullet
Mapping libraries have a lot of advantages.
Despite their advantages, mapping libraries also come with several potential drawbacks:
1. **Performance Overhead** - mapping libraries often use reflection to inspect and map object properties at runtime.
This can introduce performance overhead, especially in high-performance applications or when dealing with complex or large volumes of data.
2. **Complex configurations** - while mapping libraries aim to simplify the mapping process, they can sometimes lead to complex configurations, especially for advanced scenarios.
Configuring custom mappings, value resolvers, and type converters can become cumbersome and error-prone.
3. **Debugging Challenges** - when using mapping libraries, debugging mapping issues can be challenging.
Errors might appear only at runtime, making it harder to trace and fix problems.
4. **Error prone** - if you ever used mapping libraries in real applications, I am certain that you have run into runtime errors, only because you forgot to update the mapping profile after adding a new property to the mapping object.
So what is the best option to map objects?
It might sound shocking - but this is manual mapping. But with one interesting addition from me. Let's have a look!
## The Best Way To Do Mapping in .NET in 2024
First, let's explore entities for the blog posts application:
```csharp
public class BlogPost
{
public required Guid Id { get; init; }
public required string Title { get; init; }
public required string Content { get; set; }
public required DateTime PublishedUtc { get; set; }
public required Guid PublisherId { get; set; }
public required Publisher Publisher { get; set; }
public required List<BlogHistoryRecord> BlogHistoryRecords { get; init; } = [];
}
public class Publisher
{
public required Guid Id { get; init; }
public required string Email { get; init; }
public required string Name { get; init; }
public required string Role { get; init; }
public required List<BlogPost> BlogPosts { get; init; } = [];
}
public class BlogHistoryRecord
{
public required Guid Id { get; init; }
public required Guid BlogPostId { get; init; }
public required BlogPost BlogPost { get; init; }
public required DateTime Date { get; init; }
public required double Rating { get; init; }
}
```
We have a `BlogPost` entity, a `Publisher` entity that represents a user in the system that write blogs.
And a `BlogHistoryRecord` entity that holds information for all user ratings for each blog post.
Now, let's explore the public contract (DTO) models that are returned from the webapi:
```csharp
public record BlogPostDto
{
public required string Url { get; init; }
public required string Title { get; init; }
public required string Content { get; init; }
public required DateOnly PublishedDate { get; init; }
public required PublisherDto Publisher { get; init; }
public required double Rating { get; init; }
}
public record PublisherDto
{
public required string Name { get; init; }
public required int TotalPosts { get; init; }
public required double Rating { get; init; }
}
```
These models have interesting features:
* `BlogPost` has `Rating` property that represents the average blog rating, taking into account all the user reviews
* `PublisherDto` has `TotalPosts` and `Rating` properties.
The `Rating` property represents the average blog rating of all publisher's blogs, taking into account all the user reviews
Now let's create a mapping for these objects.
First, you need to create a static class which is a place for the mapping extension methods.
Next, you need to define mapping methods, I like making them in the following way:
```csharp
public static class BlogPostMappingExtensions
{
public static BlogPostDto MapToBlogPostDto(this BlogPost entity)
{
// ...
}
}
var blogPostDto = blogPost.MapToBlogPostDto();
```
This code is pretty straightforward as you can navigate to the `MapToBlogPostDto` method while reading the code or debugging and see exactly what is going on in the mapping.
When using mapping libraries, you need to search for the mapping profiles or extensions in the entire solution to find out how the mapping is done.
Let's explore the full mapping implementation:
```csharp
public static class BlogPostMappingExtensions
{
public static BlogPostDto MapToBlogPostDto(this BlogPost entity)
{
return new BlogPostDto
{
Url = entity.Id.ToString(),
Title = entity.Title,
Content = entity.Content,
PublishedDate = DateOnly.FromDateTime(entity.PublishedUtc),
Publisher = entity.Publisher.MapToPublisherDto(),
Rating = CalculateRating(entity.BlogHistoryRecords)
};
}
public static PublisherDto MapToPublisherDto(this Publisher entity)
{
var blogPostRatings = entity.BlogPosts
.SelectMany(x => x.BlogHistoryRecords)
.Select(x => x.Rating)
.ToList();
var averageRating = Math.Round(blogPostRatings.Average(), 2);
return new PublisherDto
{
Name = entity.Name,
TotalPosts = entity.BlogPosts.Count,
Rating = averageRating
};
}
private static double CalculateRating(List<BlogHistoryRecord> historyRecords)
{
return Math.Round(historyRecords.Average(record => record.Rating), 2);
}
}
```
Let's see the mapping in action when returning DTO models in the asp.net core minimal APIs:
```csharp
app.MapGet("/api/blogs", async (ApplicationDbContext dbContext) =>
{
var blogPosts = await dbContext.BlogPosts
.Include(b => b.Publisher)
.Include(b => b.BlogHistoryRecords)
.ToListAsync();
var blogPostDtos = blogPosts
.Select(x => x.MapToBlogPostDto())
.ToList();
return Results.Ok(blogPostDtos);
});
app.MapGet("/api/publishers", async (ApplicationDbContext dbContext) =>
{
var publishers = await dbContext.Publishers
.Include(b => b.BlogPosts)
.ThenInclude(b => b.BlogHistoryRecords)
.ToListAsync();
var publisherDtos = publishers
.Select(x => x.MapToPublisherDto())
.ToList();
return Results.Ok(publisherDtos);
});
```
As you have noticed, all the properties for entities and DTOs are marked as **required**.
This **secret addition** I find as the game changer in the object mapping.
Whenever you create mapping, you're not able to forget to map a property.
Let's see this in practice. We are going to modify the `BlogPost` entity and add two new properties:
```csharp
public class BlogPost
{
// ...
public required string Description { get; set; }
public required string Category { get; set; }
}
```
And let's suppose that we forget to update the mapping, let's compile our application:
Our application doesn't compile and we receive a list of compilation errors that are easy to fix.
## Summary
I think that **manual mapping** with **required properties** is the best way to do the object mapping in 2024.
Let's recap why this approach is better than using mapping libraries:
* Following this approach, while reading the code, you can exactly see what is going on in the mapping.
You don't need to search for mapping classes in the entire application to understand how the libraries do the mapping magic.
* You have code safety. If you forget to update the mapping method - a compiler error is raised.
* You have entire control over the mapping process, you don't need to spend time learning how to do the fancy mapping stuff in the libraries.
* This approach is much more performant as no reflection is required during the runtime
* Debugging is straightforward. Have you ever tried to step into the breakpoint in the mapping profile while debugging a mapping library?
This is really hard or almost impossible to do. Forget about this problem and have the stress-less debugging.
Hope you find this blog post useful. Happy coding!

During data feeding, cuDF allows for the parallel processing on NVIDIA GPUs which, in turn, may be effective in large data operations. The next blog will give an overview as what cuDF is, major current functionalities related to cuDF and how to perform data manipulation using cuDF.
## What is cuDF?
cuDF is a GPU DataFrame library which is pandas like for handling data on GPU. It enables data scientists and engineers to work with large amounts of data and carry out in-memory processing, thus it is ideal for pre-processing steps.
## Key Features of cuDF
1. High Performance: Due to the use of the GPUs, the cuDF is able to perform data operations faster than that of the other CPU based libraries.
2. Pandas Compatibility: cuDF is built to have a similar interface to pandas so that users of pandas do not have to learn how to use a new system but can transfer over to using the GPU-based system instead.
3. Seamless Integration: cuDF is interoperable with other tensor libraries in the RAPIDS ecosystem such as cuML for machine learning and cuGraph for graph analytics.
## Getting Started with cuDF
Now, without further ado, let’s go over the basic setup and how to use cuDF for data manipulation.
**Step 1: Installing cuDF**
First of all, it is necessary to mention that the use of cuDF is possible in case if the user has a proper NVIDIA GPU, as well as the suitable version of CUDA toolkit. Accordingly, you can download it from [Rapids AI ](https://docs.rapids.ai/install)
This is the command which I got from Rapids AI installation guide for my system
```
conda create -n rapids-24.06 -c rapidsai -c conda-forge -c nvidia \
rapids=24.06 python=3.11 cuda-version=12.2
```
**Step 2: Importing cuDF**
```
import cudf
import numpy as np
import pandas as pd
```
**Step 3: Creating a cuDF DataFrame**
You can create a cuDF DataFrame from various data sources, including pandas DataFrames, CSV files, and more.
```
# Create a cuDF DataFrame from a pandas DataFrame
pdf = pd.DataFrame({
'a': np.random.randint(0, 100, size=10),
'b': np.random.random(size=10)
})
gdf = cudf.DataFrame.from_pandas(pdf)
print(gdf)
```
**Step 4: Data Manipulation with cuDF**
cuDF provides a rich set of functions for data manipulation, similar to pandas.
```
# Adding a new column
gdf['c'] = gdf['a'] + gdf['b']
# Filtering data
filtered_gdf = gdf[gdf['a'] > 50]
# Grouping and aggregation
grouped_gdf = gdf.groupby('a').mean()
print(grouped_gdf)
```
**Step 5: Reading and Writing Data**
cuDF supports reading from and writing to various file formats, such as CSV, Parquet, and ORC.
```
# Reading from a CSV file
gdf = cudf.read_csv('data.csv')
# Writing to a Parquet file
gdf.to_parquet('output.parquet')
```
**Step 6: Performance Comparison with Pandas**
```
import time
# Create a large pandas DataFrame
pdf = pd.DataFrame({
'a': np.random.randint(0, 100, size=100000000),
'b': np.random.random(size=100000000)
})
# Create a cuDF DataFrame from the pandas DataFrame
gdf = cudf.DataFrame.from_pandas(pdf)
# Timing the pandas operation
start = time.time()
pdf['c'] = pdf['a'] + pdf['b']
end = time.time()
print(f"Pandas operation took {end - start} seconds")
# Timing the cuDF operation
start = time.time()
gdf['c'] = gdf['a'] + gdf['b']
end = time.time()
print(f"cuDF operation took {end - start} seconds")
```
From the image we can see that cuDF is 40 times more faster than pandas
**Step 7: Using cuDF as a no-code-change accelerator for pandas**
```
%load_ext cudf.pandas
```
```
# Pandas operations now use the GPU!
import pandas as pd
import time
# Create a large pandas DataFrame
pdf = pd.DataFrame({
'a': np.random.randint(0, 100, size=100000000),
'b': np.random.random(size=100000000)
})
# Timing the pandas operation with cudf.pandas
start = time.time()
pdf['c'] = pdf['a'] + pdf['b']
end = time.time()
print(f"Pandas operation with cuDF loaded took {end - start} seconds")
```
We can see from the image that it gives almost similar performance compared to using cuDF APIs
**Conclusion**
cuDF is the equipping methodology to speed up data processing pipelines by using the parallel computing system, GPUs. This is the tool’s biggest strength: Since its usage directly corresponds with pandas, users can switch and start enjoying the performance improvements quickly. Thus, with the help of cuDF lets incorporate it in data science movement, which will help to work with larger datasets and perform complex operations faster than conventional computers.

1,895,829 | Install Keycloak on ECS(with Aurora Postgresql) | Welcome If you have read my latest post about accessing RHEL in the cloud, you may notice... | 27,806 | 2024-06-21T11:06:27 | https://blog.3sky.dev/article/202407-keycloak-install/ | aws, keyclock, ecs, cdk | ## Welcome
If you have read my latest post about accessing RHEL in the cloud,
you may notice that we’re accessing the cockpit console,
via SSM Session manager port forwarding.
That’s not an ideal solution. I’m not talking in bed,
it’s just not ideal(but cheap). Today I realised that using
Amazon WorkSpaces Secure Browser could be interesting, and fun as well.
Unfortunately, this solution required an Identity Provider,
which can serve us with SAML 2.0. The problem is, that most of the
providers like [Okta](okra) or [Ping](ping),
are enterprise-oriented, and you can’t play with them easily.
Of course, you can request a free trial, but it’s 30 days only,
and there is no single-user account.
That is why I decided to use [Keycloak](keycloak).
Then I just need to decide where to deploy it, in the cloud or in the home lab.
Thankfully we have a mind map.
That is why, today we will install Keycloak on AWS,
and in part two, we will connect it with WorkSpaces
and access the RHEL console over the cockpit, as an enterprise-like user.
## Keycloak intro
But hey! What is the Keycloak? In simple words it is
Open Source Identity and Access Management tool.
Also, Keycloak provides user federation, strong authentication,
user management, fine-grained authorization, and more.
You can read more on the GitHub project
[page](https://github.com/keycloak/keycloak), and star it as well.
## Services list
To make it a bit more interesting, I will deploy it with:
- ECS(Fargate)
- AWS Application Load Balancer
- separate database, where today we will play with Serverless Aurora in MySQL mode
- Route53 for domain management
Ok, good. Finally, we will deploy something different right?
## First steps
At the beginning, I’d recommend building basic projects with networks,
ECS components, database, and ALB. Let’s call it *an almost dry test*.
Just take a look at the code, and break it into smaller parts.
```typescript
import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as ec2 from 'aws-cdk-lib/aws-ec2';
import * as rds from 'aws-cdk-lib/aws-rds';
import * as ecs from 'aws-cdk-lib/aws-ecs';
import * as elbv2 from 'aws-cdk-lib/aws-elasticloadbalancingv2'
```
On top, as you can see, I have imports. It’s worth to mention,
that AWS Aurora Serverless V2 is using `aws-rds` package, and modern load balancers,
like ALB is included in `aws-elasticloadbalancingv2`, not standard `aws-elasticloadbalancing`.
Firstly we have a network. Today we will have regular 3-tier architecture,
with a really small mask - `/28`, which means 11 IPs; regular 16 - 5 (AWS specific).
Besides of that two AZs for Aurora HA, so 2 NAT Gateways as well.
```typescript
const vpc = new ec2.Vpc(this, 'VPC', {
ipAddresses: ec2.IpAddresses.cidr("10.192.0.0/20"),
maxAzs: 2,
enableDnsHostnames: true,
enableDnsSupport: true,
restrictDefaultSecurityGroup: true,
subnetConfiguration: [
{
cidrMask: 28,
name: "public",
subnetType: ec2.SubnetType.PUBLIC
}, {
cidrMask: 28,
name: "private",
subnetType: ec2.SubnetType.PRIVATE_WITH_EGRESS
}, {
cidrMask: 28,
name: "database",
subnetType: ec2.SubnetType.PRIVATE_ISOLATED
}
]
});
```
Next we very simple setup of the application load balancer.
It’s listed on port 80(no TLS), it’s internet facing, and exists in our VPC,
inside subnets with type “PUBLIC”.
```typescript
const alb = new elbv2.ApplicationLoadBalancer(this, 'ApplicationLB', {
vpc: vpc,
vpcSubnets: {
subnetType: ec2.SubnetType.PUBLIC,
},
internetFacing: true
});
const listener = alb.addListener('Listener', {
port: 80,
open: true,
});
});
```
Here the same, we have a very basic setup of Postgres Aurora, without security groups
or deletion protection.
However, we’re setting it in the correct set of subnets,
and what is more important we’re checking our Postgres engine version,
as `the latest` is not always supported. If you would like to check it
on our own, here is the command, which shows you available engines.
```bash
aws rds describe-db-engine-versions \
--engine aurora-mysql \
--filters Name=engine-mode,Values=serverless
```
**BUT**, if you would like to use Aurora Serverless V2, you need to use `rds.DatabaseCluster`,
so our code will be, and as you can see we can use a higher version of Postgres:
```typescript
new rds.DatabaseCluster(this, 'AuroraCluster', {
engine: rds.DatabaseClusterEngine.auroraMysql(
{version: rds.AuroraMysqlEngineVersion.VER_2_11_4}
),
vpc: vpc,
credentials: {
username: 'keycloak',
// WARNING: This is wrong, do not work this way
password: cdk.SecretValue.unsafePlainText('password')
},
// NOTE: use this rather for testing
deletionProtection: false,
securityGroups: [auroraSecurityGroup],
vpcSubnets: {
subnetType: ec2.SubnetType.PRIVATE_ISOLATED
},
writer: rds.ClusterInstance.serverlessV2('ClusterInstance', {scaleWithWriter: true})
});
```
Great, now we can configure:
- ECS Cluster with Fargate Capacity Providers
- Fargate Task Definition
- container
- ECS Service
- ALB TargetGroup registration
and check if we will be able to
access our container from the regular Internet.
```typescript
const ecsCluster = new ecs.Cluster(this, 'EcsCluster', {
clusterName: 'keycloak-ecs-cluster',
// NOTE: add some logging
containerInsights: true,
enableFargateCapacityProviders: true,
vpc: vpc
})
const ecsTaskDefinition = new ecs.FargateTaskDefinition(
this,
'TaskDefinition',
{
memoryLimitMiB: 512,
cpu: 256,
runtimePlatform: {
operatingSystemFamily: ecs.OperatingSystemFamily.LINUX,
cpuArchitecture: ecs.CpuArchitecture.X86_64
}
});
const container = ecsTaskDefinition.addContainer('keycloak', {
image: ecs.ContainerImage.fromRegistry('nginx'),
portMappings: [
{
containerPort: 80,
protocol: ecs.Protocol.TCP
}
]
});
const ecsService = new ecs.FargateService(this, 'EcsService', {
cluster: ecsCluster,
taskDefinition: ecsTaskDefinition,
vpcSubnets: {
subnetType: ec2.SubnetType.PRIVATE_WITH_EGRESS
}
});
ecsService.registerLoadBalancerTargets({
containerName: 'keycloak',
containerPort: 80,
newTargetGroupId: 'ECS',
listener: ecs.ListenerConfig.applicationListener(
listener,
{ protocol: elbv2.ApplicationProtocol.HTTP })
},);
```
As you see the logic here is straightforward.
First, we need a cluster, with enabled FargateCapacityProvider,
and we would like to place it in our VPC.
Then we have a task, that needs to be an instance of class `ecs.FargateTaskDefinition`.
Next, we’re adding a container object with a Nginx docker image and port mapping.
Additionally, we need a service that combines all elements.
At the end, we register our service, as Load Balancer Target.
This configuration should allow us to validate our application skeleton,
and make sure that basic components are up, and we don’t mess something.
That is how I like to work, make a simple landscape, then tweak it according to the needs.
## Keycloak configuration
Now, we need to clarify a few things.
First, as we’re planning to run Keycloak in container, that is why we need
to go through [this doc](https://www.keycloak.org/server/containers),
then as we’re using Aurora, we need [this](aurora).
Second, there is no support for IAM Roles, which is why we need to use a username/password.
However, if you feel stronger than me with AWS SDK for Java,
and have some time, I’m sure that the Keycloak team will be more than happy to review your PR.
So after reading the documentation, looks like I need to add the JDBC driver to the image,
which requires building a custom image. It will be very simple
but require some project modification. Additionally, we need some environment variables:
```typescript
const container = ecsTaskDefinition.addContainer('keycloak', {
image: ecs.ContainerImage.fromRegistry('quay.io/keycloak/keycloak:24.0'),
environment: {
KEYCLOAK_ADMIN: "admin",
KEYCLOAK_ADMIN_PASSWORD: "admin",
KC_DB: "postgres",
KC_DB_USERNAME: "keycloak",
KC_DB_PASSWORD: "password",
KC_DB_SCHEMA: "public",
KC_LOG_LEVEL: "INFO, org.infinispan: DEBUG, org.jgroups: DEBUG"
},
portMappings: [
{
containerPort: 80,
protocol: ecs.Protocol.TCP
}
]
});
```
## Stop. Why it doesn’t work?
Look good right? No, no, and no! Making this project work
forced me to spend much more time than I expected. Why? That’s simple,
Keycloak is complex software, which is why a lot of configuration is
needed. However, let’s start from the beginning.
### Building custom docker image
I decided, that a public docker image from Aurora support would be great,
and maybe helpful for someone. That is why you can find it on [quay](quay).
Also whole project repo is public, and accessible [here](keycloak-aurora).
Besides GitHub Actions, Dockerfile is the most important part, so here we go:
```Dockerfile
ARG VERSION=25.0.1
ARG BUILD_DATE=today
FROM quay.io/keycloak/keycloak:${VERSION} as builder
LABEL vendor="3sky.dev" \
maintainer="Kuba Wolynko <kuba@3sky.dev>" \
name="Keyclock for Aurora usage" \
arch="x86" \
build-date=${BUILD_DATE}
# Enable health and metrics support
ENV KC_HEALTH_ENABLED=true
ENV KC_METRICS_ENABLED=true
ENV KC_DB=postgres
ENV KC_DB_DRIVER=software.amazon.jdbc.Driver
WORKDIR /opt/keycloak
# use ALB on top, self-sign is fine here
RUN keytool -genkeypair \
-storepass password \
-storetype PKCS12 \
-keyalg RSA \
-keysize 2048 \
-dname "CN=server" \
-alias server \
-ext "SAN:c=DNS:localhost,IP:127.0.0.1" \
-keystore conf/server.keystore
ADD --chmod=0666 https://github.com/awslabs/aws-advanced-jdbc-wrapper/releases/download/2.3.6/aws-advanced-jdbc-wrapper-2.3.6.jar /opt/keycloak/providers/aws-advanced-jdbc-wrapper.jar
RUN /opt/keycloak/bin/kc.sh build
FROM quay.io/keycloak/keycloak:${VERSION}
COPY --from=builder /opt/keycloak/ /opt/keycloak/
ENTRYPOINT ["/opt/keycloak/bin/kc.sh"]
```
Worth mentioning is the fact, that the `build` command needs to be
executed after getting `aws-advanced-jdbc-wrapper`,
or enabling health checks. Also, I’m using a self-sign certificate
as AWS will provide public cert on the ALB level.
### Documentation
When you are going through official Keycloak documentation
you will be able to read something like this:
~~I’m not a native speaker, so for me, it means:
*Put `aws-wrapper` into your JDBC URL*. But, it’s not true.
It means that the result will be `jdbc:aws-wrapper:postgresql://`,
which is not what the application can consume!
To work with Aurora Postgresql, our connection string must be:~~
**Edit**: I was wrong. `aws_wrapper` needs to be included in JDBC URL,
to use advanced wrapper's functions. However environment variable `KC_DB_DRIVER=software.amazon.jdbc.Driver`,
need to be present in Dockerfile before running `/opt/keycloak/bin/kc.sh build` command.
```typescript
KC_DB_URL: 'jdbc:aws-wrapper:postgresql://' + theAurora.clusterEndpoint.hostname + ':5432/keycloak',
```
**Note**: `keycloak` at the end is the database name, and can be customized.
Believe it or not, this misunderstanding costs me around the week of debugging...
### Cookie not found
When after a while I was able to start an app and type admin/admin,
I was welcomed with this error message:
**Cookie not found. Please make sure cookies are enabled in your browser.**
After some investigation, and reading [stackoverflow](stackoverflow) threads,
the decision was to add TLS and see what would happen. To do that in rather a simple
manner, a hosted zone with a public registered domain was needed. And you can read about it
setting it up [here](tld). In case of adding it to project we can simply write:
```typescript
const zone = route53.HostedZone.fromLookup(this, 'Zone', {domainName: DOMAIN_NAME});
new route53.CnameRecord(this, 'cnameForAlb', {
recordName: 'sso',
zone: zone,
domainName: alb.loadBalancerDnsName,
ttl: cdk.Duration.minutes(1)
});
const albcert = new acme.Certificate(this, 'Certificate', {
domainName: 'sso.' + DOMAIN_NAME,
certificateName: 'Testing keyclock service', // Optionally provide an certificate name
validation: acme.CertificateValidation.fromDns(zone)
});
this.listener = alb.addListener('Listener', {
port: 443,
open: true,
certificates: [albcert]
});
```
### Health check
This one is tricky. The target Group attached to the Application Load Balancer requires healthy targets.
Using the native ECS method as described above does not meet our needs, as we expected:
- dedicated path `/health`
- different port(9000), than main container port(8433)
- if we decide to stick with `/` path, we need to accept port `302`
As you see we need to change a method to a more traditional one:
```typescript
theListner.addTargets('ECS', {
port: 8443,
targets: [ecsService],
healthCheck: {
port: '9000',
path: '/health',
interval: cdk.Duration.seconds(30),
timeout: cdk.Duration.seconds(5),
healthyHttpCodes: '200'
}
});
```
**NOTE:** default HC port could be changed, but it adds additional complexity.
### Build time
Playing with ECS and database in the same CDK stack is not the best possible idea. Why?
Let's imagine the situation when your health checks are failing.
Deployment is in progress and still rolling. During this period,
you can't change your stack. But you can delete it…, and recreate it.
Even if the networking part is fast, spanning Aurora up and down,
could add to our change time by around 12 minutes.
That's not a bed, but still, it's quite easy to avoid it.
The change was simple. I created a new stack, dedicated to ECS,
and split the app into two parts:
- infra (network and database)
- ECS (container and services)
This simple action shows that the modularity of Infrastructure as Code could be more
important than we're usually thinking.
### Final declaration
Slowly going to the end, the ECS dedicated part will look like that:
```typescript
ecsTaskDefinition.addContainer('keycloak', {
image: ecs.ContainerImage.fromRegistry(CUSTOM_IMAGE),
environment: {
KEYCLOAK_ADMIN: 'admin',
KEYCLOAK_ADMIN_PASSWORD: 'admin',
KC_DB: 'postgres',
KC_DB_URL: 'jdbc:postgresql://' + theAurora.clusterEndpoint.hostname + ':5432/keycloak',
KC_DB_USERNAME: 'keycloak',
KC_DB_PASSWORD: theSecret.secretValueFromJson('password').toString(),
KC_HOSTNAME_STRICT: 'false',
KC_HTTP_ENABLED: 'false',
KC_DB_DRIVER: 'software.amazon.jdbc.Driver',
KC_HEALTH_ENABLED: 'true'
},
portMappings: [
{
containerPort: 8443,
protocol: ecs.Protocol.TCP
}, {
containerPort: 9000,
protocol: ecs.Protocol.TCP
}
],
logging: new ecs.AwsLogDriver(
{streamPrefix: 'keycloak'}
),
command: ['start', '--optimized']
});
```
### Final architecture
As we all love images, that's the final digram of our setup:
## Summary
That's the end of setting keycloak on ECS with the usage of Aurora Postgres.
I didn't see it anywhere on the Internet, so for at least a moment, that is
the only working example and blog post available publicly.
Additionally, a solution was tested with versions 24.0 and the latest 25.0.1 of
Keycloak base images. What will be next? As I mentioned at the beginning.
Setting up Worksapces with my own SSO solution, however, firstly we need to
configure Keyclock, which I’m almost sure, will be fun as well.

1,895,828 | Deploying AWS Guard Duty Malware Protection for S3 Buckets (Step-by-Step Guide) | Keep your S3 buckets safe from malware! GuardDuty scans new and updated files uploaded to your chosen... | 0 | 2024-06-21T11:06:18 | https://dev.to/aws-builders/deploying-aws-guard-duty-malware-protection-for-s3-buckets-step-by-step-guide-15l4 | guardduty, awscommunity, s3, malwareprotection | Keep your S3 buckets safe from malware! GuardDuty scans new and updated files uploaded to your chosen Amazon Simple Storage Service (S3) bucket. This automatic scanning helps identify potential malware threats before they can cause harm.
In this blog post, I will walk you through a step-by-step guide on how to deploy AWS Guard Duty malware protection for S3.
## Configuring Guard Duty Malware Protection
Navigate to the AWS portal, and search for guard duty.
On the guard duty home page, click on “Get Started” after selecting the radio button next to the “Guard Duty malware protection for S3 only”.
You will be redirected to the Guard duty console where we need to enable the S3 bucket configuration.
Under the “protected buckets” section click on “Enable malware protection for S3”.
In the “Enable malware protection for S3” wizard, select the S3 bucket you need to protect using Guard Duty. You can click on “Browse S3” and select the bucket you need to protect.
You need to do this exercise repeatedly if you have multiple buckets to add.
Under the prefix, you can select the radio button if you want to scan all the files or any specific types of files.
Under “Tag scanned objects” select the radio button next to the “Tag objects”.
The objects will be tagged as “THREATS_FOUND” if guard duty detects any file containing malware. It will tag the devices without malware as “NO_THREATS_FOUND”.There are additional object tags like ACCESS_DENIED or FAILED based on the scan result.
Guard Duty needs IAM permissions such as Read/Tag S3 objects, send to event bridge, and more. The pre-configured permission JSON file can be copied from the “View permissions” option under “permissions”.
First, create an IAM policy and copy the contents from the JSON file. Once you create the policy, the policy needs to be linked to an IAM role.
The IAM Role trust entities need to be configured to allow the “malware-protection-plan.guardduty.amazonaws.com” Service as shown in the screenshot below.
Click on “Enable” to enable the protection.
## Testing the Functionality.
"Important Note: Uploading actual malware is not recommended as it could be harmful. To test GuardDuty functionality, we can leverage a safe test file provided by the European Institute for Computer Anti-Virus Research (EICAR) specifically designed for this purpose. Download the test file from the EICAR website.
I uploaded the test malware file to my S3 bucket. The guard duty scanned the file and created a tag with the key pair as {"GuardDutyMalwareScanStatus": "THREATS_FOUND"}.
I tested by uploading a normal file without any malware and the guardduty created a tag with the key pair as {"GuardDutyMalwareScanStatus": "NO_THREATS_FOUND"}.
We can configure Quarantine rules via event bridge and lambda to move the malware files to a different S3 bucket created for Quarantine or to delete them immediately.
## Guard Duty malware Protection for S3 Pricing
Guard duty malware protection for S3 charges you $0.60 per GB and also $0.215 per 1000 PUT requests.

1,895,824 | Why Hiring a PHP Developer is Essential for Your Web Development Needs | In today's digital era, having a robust online presence is crucial for businesses of all sizes.... | 0 | 2024-06-21T11:01:04 | https://dev.to/dylan_9f5acebc434b82ee41f/why-hiring-a-php-developer-is-essential-for-your-web-development-needs-5cb | hire, php, developers |
In today's digital era, having a robust online presence is crucial for businesses of all sizes. Whether you are a startup or an established enterprise, your website serves as the cornerstone of your digital identity. One of the most effective ways to ensure a high-quality, dynamic, and scalable website is by hiring a skilled PHP developer. PHP, or Hypertext Preprocessor, is a widely-used open-source scripting language that is especially suited for web development. Here’s why [hiring a PHP developer](https://www.aistechnolabs.com/hire-php-developers/ ) is a strategic move that can elevate your web projects.
**The Versatility of PHP**
PHP is known for its versatility and ease of use. It powers a significant portion of the web, including major platforms like WordPress, Facebook, and Wikipedia. PHP developers can create everything from small business websites to complex web applications. Here are some key reasons why PHP remains a popular choice:
**Open Source:** PHP is free to use, which means no licensing costs. This makes it an economical option for businesses.
**Compatibility:** PHP is compatible with a wide range of databases, including MySQL, PostgreSQL, and MongoDB.
**Framework Support:** PHP has robust frameworks like Laravel, Symfony, and CodeIgniter that streamline development and enhance performance.
**Community Support:** A large and active community provides continuous support, updates, and a wealth of resources.
Benefits of Hiring a PHP Developer
**1. Custom Solutions**
A professional PHP developer can tailor your website or web application to meet your specific needs. Whether you need a custom content management system, an e-commerce platform, or a social networking site, a PHP developer can deliver a solution that aligns with your business goals.
**2. Scalability**
As your business grows, so do your web development needs. PHP developers can create scalable applications that can handle increasing traffic and data. They can optimize your site for performance, ensuring it remains fast and responsive as your user base expands.
**3. Security**
Security is a top priority for any online business. PHP developers are well-versed in best practices for securing web applications. They can implement measures to protect against common threats like SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
**4. Maintenance and Support**
Hiring a PHP developer ensures that your website is not only built to high standards but also maintained and updated regularly. They can provide ongoing support to fix bugs, add new features, and ensure compatibility with the latest web technologies.
**How to Hire the Right PHP Developer**
**1. Define Your Requirements**
Before starting the hiring process, clearly outline your project requirements. Determine the scope of the project, the features you need, and any specific skills or experience required.
**2. Look for Relevant Experience**
Check the developer’s portfolio and past projects to ensure they have experience in similar projects. Look for developers who have worked with the PHP frameworks and tools relevant to your project.
**3. Evaluate Technical Skills**
Assess the technical skills of potential candidates through coding tests, technical interviews, and reviewing their contributions to open-source projects. Key skills to look for include proficiency in PHP, experience with databases, knowledge of front-end technologies (HTML, CSS, JavaScript), and familiarity with version control systems like Git.
**4. Check References and Reviews**
Reach out to previous clients or employers to get feedback on the developer’s performance, reliability, and work ethic. Online reviews and ratings on platforms like Upwork, Freelancer, and LinkedIn can also provide valuable insights.
**5. Assess Communication Skills**
Effective communication is crucial for successful project collaboration. Ensure the developer can communicate clearly and effectively, both in writing and verbally. This is especially important if you are hiring a remote developer.
**Conclusion**
Hiring a PHP developer is a strategic investment that can significantly enhance your web development efforts. From creating custom solutions to ensuring scalability and security, a skilled PHP developer brings a wealth of benefits to your project. By following a structured hiring process and focusing on key skills and experience, you can find the right PHP developer to help you build a powerful, dynamic, and secure online presence.

[Fortran](http://es.wikipedia.org/wiki/Fortran) o FORmula TRANslation, es... un clásico. Lleva alrededor de 60 años con nosotros, y de hecho, su historia viene de ser el primer lenguaje de alto nivel desarrollado para *mainframes*. Y de hecho, sigue siendo así: [los mayores supercomputadores utilizan Fortran para cálculo numérico, especialmente con matrices](https://fortran-lang.org/).
Hasta hace muy poco, nadie contemplaba Fortran más allá de un lenguaje de programación de nicho. Hasta que, hace un mes, este lenguaje de programación entró en el famoso [TIOBE Index](https://www.tiobe.com/tiobe-index/), que de alguna manera es aceptado como el [índice de popularidad de cada lenguaje de programación](https://en.wikipedia.org/wiki/TIOBE_index).
¿Cómo es que un lenguaje de programación casi casi olvidado, de repente se hace un hueco entre el top-ten de los lenguajes de programación más populares?
El razonamiento es simple, o al menos, tiene sentido: Python es el lenguaje de programación más amado por todos, por su simpleza y su potencia, pero tiene un gran defecto: resulta que es lento. Efectivamente, Python es traducido a un *bytecode* que después es interpretado. De hecho, buena parte de las extensiones disponibles para Python (NumPy, Numba...), intentan paliar este problema dando soporte explícito para matrices y cálculo numérico desde código compilado mediante C, mediante la interfaz con este lenguaje de programación que proporciona Python. El siguiente paso es compilar Python, pero debido a su naturaleza dinámica, no es un paso sencillo. Otros lenguajes de programación que reclaman mayor velocidad de ejecución aún siendo dinámicos, como Julia, demuestran esta dificultad, pues no están maduros. ¿Hay algún otro lenguaje de programación compilado (y por lo tanto, rápido), que soporte cálculo numérico y matrices? Pues sí, y es que siempre lo ha habido: Fortran.
Fortran está viviendo un relanzamiento basado en este punto. El plan consiste en crear un nuevo compilador que aproveche las ventajas más recientes de los ordenadores personales. Por ejemplo, en este momento no se aprovecha de la capacidad del procesador de la tarjeta gráfica.
Para mi un problema (sí, un tanto superficial, lo sé), es que tiene un cierto tufillo antiguo, como demasiado clásico.
```fortran
program CalculaHipotenusa
real :: cateto1
real :: cateto2
real :: hipotenusa
print *, "Dame el cateto 1: "
read(*, *) cateto1
print *, "Dame el cateto 2: "
read(*, *) cateto2
hipotenusa = sqrt( cateto1 ** 2 + cateto2 ** 2 )
print *, "La hipotenusa es: ", hipotenusa
end
```
¿Es Fortran el nuevo Python? Pues habrá que verlo. Sin duda, sería sorprendente.

So,... | 0 | 2024-06-21T10:50:03 | https://dev.to/jigar_online/appealing-mobile-app-design-understanding-its-3-important-pillars-4bhi | learning, mobile, design, mobileapp | Mobile apps are a must-have component for businesses to succeed in today's fast-tech times. So, whether you are an established company or a startup, considering mobile app development helps you enhance client engagement and reach a larger audience. And for a successful mobile app, you must first have a successful app design.
_"Vision is the art of seeing what is invisible to others." - Jonathan Swift_
Unlike any other art, mobile app designing will help bring massive value to any business. It will give the first impression to your users. The first impression is the last. And as per [Verified Market Research](https://www.verifiedmarketresearch.com/product/app-design-software-market/), you can expect the app design software market to reach USD 464.9 billion by 2027.
Mobile app design enhances the user experience and helps optimize the app's overall aesthetics, performance, and functionality. However, designing a functional and visually appealing app can be challenging. So, to ensure a successful result, you'll need a trusted mobile app development company, good strategies, careful planning, and seamless execution.
Therefore, this blog will discuss the three essential stages of designing mobile apps. Knowing and understanding these stages is vital for building a user-friendly and successful application.
Without any wait, let's dive into the pool of information!
## Three Vital Stages for Successful Mobile App Design
**1. Planning and Conceptualization**
The planning and conceptualization phase is the first important step of mobile app design. At this stage, you lay the groundwork for your mobile app's efficiency by specifying its objective, target audience, and features. Let's elaborate on these essential pointers:
- **Determine Your App Objectives** - Before starting with your mobile app design, you must understand the app's primary goals and purposes. Consider the objectives of your app, the problems it will solve, the app's primary features, how it will gain a competitive edge in the market, and so on.
- **Identify Your Target Users** - Knowing and understanding your target audience is essential when developing a user-centric app. You need to look out for aspects like gender, age, interests, location, behavioral patterns, and preferences when determining your user personas. These details will help you design and build a mobile app that resonates with your target audience.
- **Extensive Market Research** - Conducting thorough market research is essential to understand user expectations and the competitive landscape. You can also examine similar apps for any new feature or loophole. All in all, it will help you identify gaps and possibilities to make your app unique.
- **App Sketch and Wireframe** - Once your app vision is clear, you can start with your app sketching and wireframing. These visual illustrations of your app's design and features will help you study different user flows and design ideas.
- **Plan Information Architecture and User Flow** - Time to plan your app's information architecture and user flow. This step involves determining how users browse through your app, what screens users will come across, and the number of advanced features. Therefore, building an intuitive and logical flow that guides your customers through the app smoothly is essential.
**2. Design and Prototyping**
The second significant phase of mobile app design is developing your app's visual and responsive components. In this phase, you bring your app idea to life and create the user interface.
**2.1) UI (User Interface) Design** - User interface design concentrates on your app's visual elements. It includes:
- **Layout and Structure** - Design an intuitive blueprint that makes it effortless for customers to find whatever they need with a single click.
- **Icons and Images** - Design custom icons and utilize high-quality images to improve the visual appeal.
- **Typography** - Choose the fonts that enhance your app's style and are easy to read.
- **Color Scheme** - Opt for a color scheme that complements your brand and entices your target users.
**2.2) UX (User Experience) Design** - User experience design ensures your app is user-centric and offers a pleasant and seamless experience. So, consider the following factors:
- **User Testing** - You must perform user testing to improve the user experience and detect any usability issues.
- **Feedback** - It offers feedback and reviews to users when they perform specific activities, such as form submissions or button clicks.
- **Interactivity** - Leverage responsive elements like gestures, forms, and buttons to interact with users.
- **Navigation** - Design a clean and steady navigation system that makes it simple for users to navigate through the app.
**2.3) Prototyping** - Build engaging app prototypes to test their practicality and collect feedback. Prototypes are valuable for discovering design flaws or usability issues that might not appear in static mockups.
**2.4) Responsive Design** - In today's mobile-centric era, it's essential to integrate responsiveness in your app design. You must ensure your app is top-notch and functions well on multiple devices.
**3) Development and Testing**
The third and last stage of mobile app design involves app development and severe testing to ensure it accomplishes your design and functionality objectives.
**3.1) Development** - Deploy the best mobile app design services and partner with expert developers to give your app design life. Following are the pointers to consider:
- **Follow Design Guidelines** - Ensure you implement the design per the guidelines during the design stage.
- **Iterative Development** - You can work in iterations, as it helps with consistent testing and optimizing your app's features and functionalities.
- **Regular Communication** - Maintain open and transparent communication with your development team to address design or development concerns.
**3.2) Testing** - Testing is crucial to recognize and rectify any issues before publishing your mobile app. Following are some testing considerations:
- Functionality Testing
- Compatibility Testing
- Performance Testing
- Usability Testing
- Security Testing
**3.3) Beta Testing** - Before publishing your app, it's essential to perform the beta testing with a particular group of users. This will provide valuable insights and help you make all final modifications based on real-world utilization.
**3.4) User Feedback and Iteration** - The app design process continues after your app launch. Wondering how? It collects user feedback and checks app analytics to recognize any scope for improvement.
## Summing Up!
A mobile app design's work doesn't get over after the app launch; the design and development process continues as you add new features and integrate user input. Every project is unique, and so is its nature; therefore, you may be given more options or asked more queries than usual. The design, development, and release of your mobile apps will blow up (of course, in a good way) without any obstacles if you follow this 3-step mobile app design approach.

- Create a table in the database named "notes" with the following columns:
- id (unique index)
- title
- content
- The "id" column is the primary key and has a unique index, allowing for efficient location of specific data.
- The "title" column stores the note title.
- The "content" column stores the note content.
- Sample data in the "notes" table:
- id | title | content
- --- | --- | ---
- 1 | Note 1 | I am a frontend developer .
- 2 | Note 2 | I am a backend developer .
- 3 | Note 3 | I am a blogger.
- 4 | Note 4 | I am a YouTuber.
- The unique index on the "id" column enables fast lookup and retrieval of specific notes by their ID.
## Diving in code
In a fresh vs code project (version 1.90 at the time of working), we need two different files to easily learn the working of code.
## On VS Code Side
Create two files named `notes.php` and `note.php`.
- The "notes.php" file is used to:
- Fetch all notes from the database
- Display a list of all notes on the screen
While,
- The "note.php" file is used to:
- Fetch a single note from the database using its unique ID (index)
- Display the content of a single note on the screen
## Connection to database
- As before fetching notes, a connection with the database must be made and configured as described earlier.
## Add Notes link in nav file
- Add a link in the navigation file (nav.php) that, when clicked, directs to the notes screen (notes.php).
```html
<a href="notes.php">Notes</a>
```
Different notes are showing on that page.
```php
<?php
$config = require('config.php');
$db = new Database($config['database']);
$heading = 'My Notes';
$notes = $db->query('select * from notes where user_id = 1')->fetchAll();
require "views/notes.view.php";
```
But when a user wants to view a specific note on the screen, a superglobal variable (e.g., $_GET or $_POST) is used to retrieve the note ID from the user's request, and then the corresponding note is displayed on the screen.
```php
<?php
$config = require('config.php');
$db = new Database($config['database']);
$heading = 'Note';
$note = $db->query('select * from notes where id = :id', ['id' => $_GET['id']])->fetch();
require "views/note.view.php";
```
If the user enters the wrong id to find note that is not in database table then a 404 error page is shown on screen with a link 🖇️ to go back to home.
I hope that you have clearly understand each and everthing easily. | ghulam_mujtaba_247 |

1,895,812 | Pure Functions in Next.js | Introduction While working with Next.js, a very famous React framework for building server-side... | 0 | 2024-06-21T10:46:35 | https://dev.to/sabermekki/pure-functions-in-nextjs-4ni4 | react, nextjs, javascript, webdev | **Introduction**
While working with Next.js, a very famous React framework for building server-side rendered and static web applications, one of the very important concepts you are going to meet is a pure function. Pure functions are among those principal topics one has to grasp in functional programming and take a huge part in making your code reliable and serviceable. We shall look into what exactly a pure function is, why it is important, and how to use one effectively within a Next.js application.
---
**What is a Pure Function?**
A pure function could be defined as a function that meets the following two basic requirements:
- **Deterministic**: It always returns the same output for a given input.
- **Side-effect Free**: It has no side effects; that is, it does not
modify any state or have an effect on the world outside.
The next example will be a pure function. JavaScript provides a very good example of such a function:
```
function add(a, b) {
return a + b;
}
```
No matter which a and b are passed to this function, it will always yield the same value and has no side effects, nor does it mutate any external state.
---
**Why Use Pure Functions?**
Pure functions have the following benefits:
- **Predictability**: Since pure functions always return the same output for any given input, they become more predictable and easier to reason about during debugging. It means that pure functions can be tested in isolation without mocking external dependencies.
- **Immutability**: There are no side effects inside pure functions, resulting in much safer, more reliable code.
---
**Pure Functions in Next.js**
Pure functions can be utilized in various areas of your Next.js app, from components and utility functions to data transformations.
**Components**
React components can also be pure functions. In fact, all functional components are pure functions where props are passed as an argument returning a React element as the result. The following is an example of a pure functional component in Next.js:
```
import React from 'react';
function SayHello(name) {
return <h1>Hello, {name}!</h1>;
};
export default SayHello;
```
This component is pure because it always returns the same output for the same props and has no side effects.
**Functions**
All utility functions used in your Next.js application should be pure as well
A utility function that capitalizes the first letter of a string:
```
export function capitalizeFirstLetter(string) {
return string.charAt(0).toUpperCase() + string.slice(1);
}
```
This function is pure because it consistently returns the same output for the same input without modifying any external state.
---
**Fetching Data and Side Effects**
While pure functions are a cornerstone, not all functions in a Next.js application can or should be pure. This is true, for example, of data fetching functions. By definition, they have side effects – they make requests to external APIs or databases.
In Next.js, data fetching generally occurs through functions like **getStaticProps **or **getServerSideProps**, which are explicitly designed to run side effects. Such functions are not pure, but they isolate side effects to parts of your application so that the rest is more tractable.
As for a concrete example of data fetching in Next.js, here it is:
```
export async function getStaticProps() {
const res = await fetch('https://api.example.com/data');
const data = await res.json();
return {
props: {
data,
},
};
}
```
---
**Combining Pure and Impure Functions**
In practice, a Next.js application will contain pure and impure functions. However, what is important is that you isolate the impure ones and keep the maximum portion of your codebase pure. This will bring semantic epithets and ensure maintainability for your app.
As such, you can isolate concerns into pure functions to format data fetched from an API the following way:
```
// Impure function
export async function fetchData() {
// fetches data from an API
}
// Pure function
export function formatData(data) {
//formats the fetched data
}
```
---
**Conclusion**
Writing pure functions is one of the cornerstones of functional programming, which can bring a huge potential improvement in the quality of your Next.js applications. With them, you guarantee that your code will become more predictable, hence more testable, and less vulnerable to bugs. Totally writing pure functions is not quite possible, but isolating side effects and keeping most of your codebase pure will make for a more maintainable and robust application.

This strategy is tailored for numerous small files. <br> 1. Plan the export path and create directories to store exported data files on each DN in the cluster, such as `"/output_data"`, and change the owner of this path to `omm`. <br> 2. Install, configure, and start GDS on the server where data will be exported. <br> 3. Create an external table in the cluster, with the location path in the format `"file:///output_data/"`. |GDS tools suitable for scenarios with high concurrency and large data exports. Utilizes multi-DN parallelism to export data from the database to data files, improving overall export performance. Does not support direct export to HDFS file system. <br><br> **Notes on Remote Export:** <br> 1. Supports concurrent export by multiple GDS services, but one GDS can only provide export services for one cluster at a time. <br> 2. Configure GDS services within the same intranet as the cluster nodes. Export speed is affected by network bandwidth. Recommended network configuration is 10GE. <br> 3. Supported data file formats: TEXT, CSV, and FIXED. Single row data size must be <1GB. <br><br> **Notes on Local Export:** <br> 1. Data will be evenly split and generated in the specified folders on the cluster nodes, occupying disk space on the cluster nodes. <br> 2. Supports data file formats: TEXT, CSV, and FIXED. Single row data size must be <1GB.|
|**gs_dump and gs_dumpall Tools** <br> `gs_dump` supports exporting a single database or its objects. <br> `gs_dumpall` supports exporting all databases in the cluster or common global objects in each database. <br> The tools support exporting content at the database level, schema level, and second level. Each level can be separately defined to export the entire content, only object definitions, or only data files.|**Step 1:** The `omm` operating system user logs into any host with MPPDB service installed and executes: `source $ {BIGDATA_HOME}/mppdb/.mppdb` <br><br> `gs_profile` command to start environment variables <br><br> **Step 2:** Use `gs_dump` to export the postgres database: `gs_dump -W Bigdata@123 -U jack -f /home/omm/backup/postgres_backup.tar -p 25308 postgres -F t`|1. Export the entire database information, including data and all object definitions. <br> 2. Export the full information of all databases, including each database in the cluster and common global objects (including roles and tablespace information). <br> 3. Export only all object definitions, including: tablespace, database definitions, function definitions, schema definitions, table definitions, index definitions, and stored procedure definitions. <br> 4. Export only data, excluding all object definitions.|
**GDS External Table Remote Export Example:**
```
mkdir -p /output_data
groupadd gdsgrp
useradd -g gdsgrp gds_user
chown -R gds_user:gdsgrp /output_data
/opt/bin/gds/gds -d /output_data -p 192.168.0.90:5000 -H 10.10.0.1/24 -D
CREATE FOREIGN TABLE foreign_tpcds_reasons

r_reason_id char(16) not null,
r_reason_desc char(100)
) SERVER gsmpp_server OPTIONS (LOCATION 'gsfs://192.168.0.90:5000/', FORMAT 'CSV',ENCODING

**GDS External Table Local Export Example:**
```
mkdir -p /output_data
chown -R omm:wheel /output_data
CREATE FOREIGN TABLE foreign_tpcds_reasons
(
r_reason_sk integer not null,
r_reason_id char(16) not null,
r_reason_desc char(100)
) SERVER gsmpp_server OPTIONS (LOCATION 'file:///output_data/', FORMAT 'CSV',ENCODING
'utf8', DELIMITER E'\x08', QUOTE E'\x1b', NULL '') WRITE ONLY;
INSERT INTO foreign_tpcds_reasons SELECT * FROM reasons;
```
**gs_dumpall Export Example:**
Export all global tablespace and user information of all databases (omm user as the administrator), the export file is in text format.
```
gs_dumpall -W Bigdata@123 -U omm -f /home/omm/backup/MPPDB_globals.sql -p 25308 -g
gs_dumpall[port='25308'][2018-11-14 19:06:24]: dumpall operation successful
gs_dumpall[port='25308'][2018-11-14 19:06:24]: total time: 1150 ms
```
Export all database information (omm user as the administrator), the export file is in text format. After executing the command, there will be a long printout, and finally, when "total time" appears, it means the execution was successful.
```
gs_dumpall -W Bigdata@123 -U omm -f /home/omm/backup/MPPDB_backup.sql -p 25308
gs_dumpall[port='25308'][2017-07-21 15:57:31]: dumpall operation successful
gs_dumpall[port='25308'][2017-07-21 15:57:31]: total time: 9627 ms
```
Export all database definitions (omm user as the administrator), the export file is in text format.
```
gs_dumpall -W Bigdata@123 -U omm -f /home/omm/backup/MPPDB_backup.sql -p 25308 -s
gs_dumpall[port='25308'][2018-11-14 11:28:14]: dumpall operation successful
gs_dumpall[port='25308'][2018-11-14 11:28:14]: total time: 4147 ms
```
## GBase 8a MPP Data Import:
**Execute SQL file to import database definitions**
```
gccli -ugbase -pgbase20110531 -Dtestdb -vvv -f <guessdb_out.sql >>guessdb_out.result 2>guessdb_out.err
```
Note: The -D parameter must be followed by an existing database within the GBase cluster. The executed `guessdb_out.sql` file will operate according to the databases specified within the SQL file, regardless of the database specified after the -D parameter.
**GBase 8a MPP Import Text Data**
**Step 1:**
The data server where the data exported from GaussDB is located needs to be configured with FTP service. Ensure that all nodes in the GBase 8a MPP cluster can access the data files on the data server via FTP.
**Step 2:**
Organize the characteristics of the data files exported from GaussDB:
- Encoding format
- Field delimiter
- Quote character
- Null value in data files
- Escape character (default is double quotes)
- Whether the data file contains a header row
- Line break style of the exported data files
- Date format in date columns, etc.
**Step 3:**
Based on the characteristics organized in Step 2, write and execute the SQL for importing data in GBase 8a MPP.
