The business world is plagued with many challenges. These challenges require specific strategies to help you navigate them.
I’ll explain these challenges and the strategies to overcome and succeed.
## Customer acquisition
Companies invest endlessly to acquire customers. They do so to convince them that their brand is the best choice on the market.
There are many known effective strategies to attract your prospects. These strategies focus on the customer journey. This describes the path your potential customers follow from start to finish.
Marketers and writers must know each stage of the process and tailor their material accordingly.
## What is the customer journey?
The customer journey (also called the buyer's journey) is the sum of interactions that customers undergo before and after purchasing. It's a framework for business owners to fully understand their client's needs and how best to respond to them.
It includes finding out their experience and improving their buying process so they can remain loyal. Each stage of the customer journey can last from a few minutes (for instance, buying low-cost items like food) to several months (for example, purchasing a car). Businesses value repeat purchases more than one-off transactions. Life would be simpler if all an enterprise did was offer a service or product, the customer buying it and calling it a day. Buyers are more demanding and value their experience with a brand just as much as the products or services offered.

## Importance of creating content for the customer journey
Examples of content you can produce are:
- Blogs
- Videos
- Podcasts
These are a few formats. The key to connecting with prospects is to know which content will work best at a particular stage. Delivering the right content at the right time is vital.
It’s sensible to have case studies or testimonials if the buyer is familiar with your business. You can't immediately sell your product when the buyer is still figuring out what they need. Create informational content that addresses their needs and how your business can help them. Then, link CTAs (calls to action) to the next stage.
Customer journey analysis is about understanding your audience. Content marketers aim to offer material that potential buyers can relate to so they don't lose them. We utilize a unique form of marketing to keep our clientele interested and invested. We use the Crazy Marketing Strategy Goleko to enhance our marketability and customer outreach. We also utilize Engineering as Marketing. This has the theoretical and practical aspects. It teaches you how to use engineering as a form of marketing.
## <u>Stages of the customer journey and Content formats</u>
## Awareness stage
This phase lays the foundation as it's at the beginning. Potential clients realize they have a problem and look for ways to solve it. They need time to think about which companies can provide the solution.
Most people don’t include brand names in search queries. It's advisable to gather insights, opinions, and resources. Your content will revolve around words like:
- "How"
- "What"
- "Who"
- "Why"
- "Where", etc.
### Content formats in the awareness stage
Prospective buyers have just discovered your business. They aren’t quite ready to make a purchase. You have to think of content that would be purely informative and useful to help them. This content should help them make the right decision.
The best content formats here include:
- Blog posts or articles (decent long-form and shareable material)
- Videos (the most engaging content to have, which is suitable for all stages)
- Infographics (best for presenting statistical data)
- Whitepapers and e-books (best for going more in-depth on topics, where you can include infographics)
- Social media posts (ideal for short-form content to link to other more detailed content)
- Checklists (another way to offer short-form content)
- Podcasts (useful for presenting general industry information and more about your company)
- Webinars (another way of presenting expertise in your field)
>Read: [_Improved client collaboration with screen recording_](https://martinbaun.com/blog/posts/improved-client-collaboration-with-screen-recording/)
### Your role during the awareness stage
Your role is to present your business as an authority in its field. Your prospects may be oblivious that they need or want what you offer. The awareness stage should inform them of your brand and why they should care.
Content at this point is for enlightenment. Refrain from using any sales tactics. Your audience should receive upfront value in the form of useful information without any commitment.
## Consideration stage
Customers are committed to discovering the available solutions for their problems. They are more familiar with your company but will evaluate it against others.
This stage is the longest as prospects look at multiple options, going through a process of elimination. They are prepared to buy while looking for the best choice. You'll want to be on their shortlist of potential options.
Keywords to consider here are:
- "Solutions"
- "Features"
- "Best"
- "Choices"
- "Options"
- "Comparison"
- "Benefits"
- "Steps"
### Best content formats in the consideration stage
The content is informational with subtle promotion. Its goal is to compare with available solutions on the market while offering vital details about your service or product.
The most frequently used content formats for the consideration stage are:
- Product comparisons or catalogs (here, you can put your brand as the best option among others)
- Case studies (another in-depth look at the advantages of your solution)
- Cost calculators (similarly, you can position yourself as the most cost-effective option compared)
- Downloadable content (e.g., e-books, whitepapers)
- Videos
### What should you do at the consideration stage?
The goal of a business is to position itself as the best option compared to its rivals. Your content should make your product or service as attractive and trustworthy as possible.
## Decision stage
Buyers are ready to spend cash and have confidently decided on their solution strategy. Now's the right time to have content that covers all their concerns and questions before the sale. It should be direct and offer as many incentives as possible to close the sale (don't be shy).
Key sales words to use here are:
- "Discount"
- "Free trial"
- "Buy"
- "Order"
- "Don't miss out"
- "Risk-free"
- "Exclusive"
- "No strings attached"
- "Premium", etc.
>Read: _[Tips on starting a startup](https://martinbaun.com/blog/posts/tips-on-starting-a-startup/)_
### Content formats for the decision stage
The material shows that your service or product is legit and performs as advertised. The best content to achieve this goal includes:
- Reviews
- Case studies
- FAQs
- Demos
- Reviews
- Coupons
- Testimonials
- Free trials or versions
### Goal of the decision stage
Content at this stage aims to showcase why your business is simply the best. All doubts and concerns should be removed from your prospect's mind. They should trust your brand and know the steps to become your customer.
## Summary
Salespeople talk about funnels. This describes the many steps we go through before buying from a company. It might seem like a simple choice, but it's multi-layered.
We rarely make impulse buys. That's why understanding the customer journey and using tailored content for each stage is vital. Understanding the path buyers take before they engage your business is pivotal.
It goes beyond the three stages we've discussed. A business must work just as hard to retain its customers and make them loyal. If they are happy for long enough, they will eventually become advocates for your business through word-of-mouth or referrals.
You can implement these strategies to help your business flourish. Divide responsibilities among your team members and coordinate everything with the help of Goleko. Goleko has features that help you achieve your goals, including multi-layered projects.

Right?
I mean, let’s get this out of the way. The gall on that reasoning actually offends me. Like, on a deep spiritual level. Because if there’s a tenet of business that I truly believe is unflinching, it’s that you can’t cut your way to growth. Ever.
So why are all these nerds being shown the door?
Well, there are a few reasons. Most of them unavoidable, but none of them… that.
Be forewarned, I’m going to do a little speculation and opinion here, connecting dots I believe need to be connected. I don’t think I’m wrong though. Disagree with me if you feel like it.
### No One Understands AI But Everyone Thinks They Do
I swear, if I see one more article from some “expert” with a headline that screams about AI taking everyone’s job except those of us who are wise enough to learn how to use AI, I will… write a strongly worded letter to the publisher, because it’s the publisher’s fault for letting that garbage through for the clicks.
I can explain why the AI dystopia isn’t true in three words. Movies. Aren’t. Real.
AI is not Skynet. We’re not living in The Matrix. We’re not obligated to welcome our new OpenAI overlords.
The current evolution of GenAI is not going to be the AI that universally replaces knowledge-based labor. What they’re selling as the “AI” function of today’s GenAI can be more closely described as “powerful computers doing if/then statements really fast” than “sentient.”
However, GenAI is indeed a threat to SaaS, especially the business intelligence systems that create and aggregate the data that power an awful lot of other B2B SaaS. These people are freaking out. And they envision a panacea in AI — this technical marvel that can do any tech task at any tech time for less tech money.
Why pay all these high-priced software engineers to develop elegant solutions to specific business problems when we can just ask ChatGPT to solve those problems for us?
Good luck with that.
### Investors and Boards Flew Too Close To The Sun
This reason is related to AI but not solely rooted in AI. When the economy is frothy, and there is a technology evolution underway that looks like it’s game-changing, i.e. AI, investors and boards forget how to balance their checkbooks.
The three years before 2024 were, to use an economist term, batshit insane.
Free cash flow dominated those years, as well as the years leading up to the pandemic, meaning there was a ton of cash reserves to spend and spend fast. And while the pandemic looked like it was a paper tiger, in terms of Wall Street economic impact — like maybe a sneeze instead of the flu — the AI race started to heat up.
So with time of the essence and fear and opportunity on either shoulder of investors and board members everywhere, money got spent in weird ways. A lot of it fell into two categories, either on the race to adopt AI or on measures to counter AI.
I generally believe this happened because too many companies missed the boat on some of the major game-changing tech in the 20 years previous — the rise of the internet, then mobile, then cloud, then eCommerce. Everyone watched Google, then Apple, then Amazon, and then… Amazon, eat their lunch.
Oddly, the same tech cycle was playing out pre-pandemic with blockchain and NFTs — but the warning signs were overshadowed by said pandemic, and no one realized that the 800-pound gorillas in the room, Amazon and such, weren’t going after the NFT banana.
I’m so proud of that last sentence, by the way.
This time around, OpenAI and Google are indeed eating all the AI bananas, because real AI is really expensive. So investors and boards that aren’t with OpenAI or Google are mass quitting on the idea that this evolution of GenAI will be lifting all boats any time soon. Certainly not before their now-super-tight cash reserves run out.
So the tech layoffs might be for “growth,” just not the growth they had been hiring for the last three years.
### Techies Got Entitled
Yeah, let’s blame the victim a little.
Come on, folks. Did we really think this gravy train was going to last forever?
With all the demands being made by both new and veteran tech talent alike — from where we work, to how much we get paid, to a belief that maybe the business side will finally understand that triangle with time, cost, and quality on each side — at some point the squeaky wheel gets replaced, right?
I’m kidding. A bit.
But much like how too many people think they know AI, too many people on the business side now think they know tech. And when they see all these kids coming out of code schools and universities with syntax drilled into their heads and GitHub project portfolios and all the Agile/Jira terminology nailed, they think, well, that’s what coding is.
And so they hired a ton of them.
And our decades of earned resentment turned into their unearned entitlement.
They learned it from us, friends.
Now everyone is getting the ax.
### The Wrong People Are In Charge
That’s what it all boils down to.
The people in charge of telling the story of tech are selling the most dystopian story imaginable.
The people in charge of cutting the checks are chasing a swinging pendulum and scared of getting burned again.
The people in charge of building the tech are understaffed, underskilled, and overconfident.
Yeah. If you dropped this quagmire into my hands, I’d start erasing the board too. It’s unavoidable. | manojgohel |

However, with Web Workers, we can perform background tasks without blocking the main thread. Let's dive into how Web Workers enable multithreading in JavaScript! 🧙♂️
please subscribe to my [YouTube channel](https://www.youtube.com/@DevDivewithDipak?sub_confirmation=1
) to support my channel and get more web development tutorials.

8. [Conclusion](#conclusion)
### 📚 Introduction <a name="introduction"></a>
JavaScript's single-threaded nature can lead to performance issues when handling complex computations or I/O operations. Web Workers provide a way to run scripts in background threads, allowing the main thread to remain responsive. 🏃♂️
### 🤖 What are Web Workers? <a name="what-are-web-workers"></a>
Web Workers are a standard way to run JavaScript in background threads. They can execute tasks without interfering with the user interface, making your web applications smoother and more efficient.
### 🧩 Types of Web Workers <a name="types-of-web-workers"></a>
There are three types of Web Workers:
1. **Dedicated Workers**: These are used by a single script.
2. **Shared Workers**: These can be accessed by multiple scripts, even across different windows, if they belong to the same origin.
3. **Service Workers**: These act as a proxy between your web application and the network, enabling features like push notifications and background sync.
### 🛠️ Creating a Web Worker <a name="creating-a-web-worker"></a>
To create a Web Worker, you need to write the worker script and instantiate a worker in your main script.
**Worker Script (worker.js):**
```javascript
self.onmessage = function(e) {
console.log('Message received from main script');
var result = e.data[0] * e.data[1];
self.postMessage(result);
}
```
**Main Script (main.js):**
```javascript
var worker = new Worker('worker.js');
worker.onmessage = function(e) {
console.log('Message received from worker: ' + e.data);
}
worker.postMessage([10, 20]);
```
### 🗣️ Communicating with Web Workers <a name="communicating-with-web-workers"></a>
Communication between the main script and Web Workers is done through messages. The `postMessage` method sends messages to the worker, and the `onmessage` event handler receives messages from the worker.
**Main Script:**
```javascript
worker.postMessage('Hello, worker!');
worker.onmessage = function(event) {
console.log('Message from worker:', event.data);
}
```
**Worker Script:**
```javascript
self.onmessage = function(event) {
console.log('Message from main script:', event.data);
self.postMessage('Hello, main script!');
}
```
### 👨💻 Example: Using Web Workers <a name="example-using-web-workers"></a>
Let's see a practical example where a Web Worker is used to calculate Fibonacci numbers without blocking the main thread.
**Worker Script (fibonacciWorker.js):**
```javascript
self.onmessage = function(event) {
var num = event.data;
var result = fibonacci(num);
self.postMessage(result);
};
function fibonacci(n) {
if (n <= 1) return n;
return fibonacci(n - 1) + fibonacci(n - 2);
}
```
**Main Script (main.js):**
```javascript
var worker = new Worker('fibonacciWorker.js');
worker.onmessage = function(event) {
console.log('Fibonacci result:', event.data);
};
worker.postMessage(40); // Calculate the 40th Fibonacci number
console.log('Fibonacci calculation started');
```
### ⚠️ Limitations and Considerations <a name="limitations-and-considerations"></a>
While Web Workers are powerful, they have some limitations:
- **No DOM Access**: Workers cannot manipulate the DOM.
- **Same-Origin Policy**: Workers must be loaded from the same origin as the main script.
- **Performance Overhead**: Creating and managing workers involves some overhead.
Use Web Workers for CPU-intensive tasks to keep your application responsive. 🚀
### 🏁 Conclusion <a name="conclusion"></a>
Web Workers provide a powerful way to perform background tasks in JavaScript, enabling true multithreading in your web applications. By leveraging Web Workers, you can enhance the performance and responsiveness of your applications. 🌟

1,894,543 | OpenSign v1.5.0 introduces new features including custom email templates, revoke document functionality | We are excited to announce the release of OpenSign v1.5.0. This update brings a host of new features... | 0 | 2024-06-20T09:31:03 | https://dev.to/opensign001/opensign-v150-introduces-new-features-including-custom-email-templates-revoke-document-functionality-1b81 | We are excited to announce the release of OpenSign [v1.5.0.](https://github.com/OpenSignLabs/OpenSign) This update brings a host of new features and improvements to enhance your experience. The new features in this version are broken down as follows:
What’s New
Major features
1. The digital signature on completion certificate
Your completion certificate is now digitally signed. With this fantastic feature of OpenSign, you can give your documents an additional degree of authenticity and security.
To add a digital signature to your completion certificate you don’t need to take any extra steps. Once all signers have signed the document, the digital signature will be automatically attached to the completion certificate.
2. Improved security for download links
The download links for signed pdf files will expire after a few minutes. OpenSign’s this new safeguard ensures that your documents are secure and only available to authorized users. This means, even if a malicious user tries to copy the download link to your confidential document & publish it in a public forum, you are safe as the link will expire in a few minutes.
3. Custom email templates
[OpenSign](https://www.opensignlabs.com/) brings a new feature that gives you a more personalized communication experience; now users can apply customized templates for request signature emails. By enabling document owners to create and send emails that exactly suit their own requirements and preferences, it helps to improve overall communication with their recipients.
4. ‘Revoke’ button in In-progress report
In the ‘In-progress’ report, we have added a revoke button. This feature allows you to easily decline or revoke documents, this feature giving you a better control over document workflows.
5. Add recipient button in Request signatures flow
We’ve introduced an “Add recipient” button in the request signature flow, to make it easier to add new signers to the document. This helps you quickly add new signers even while editing a document if you miss a signer at the time of creating one.
6. Delete and Share buttons in reports
The addition of delete buttons in all reports and share buttons in the in-progress report enhances document management capabilities. You can click the share button available in the ‘In-progress’ report to quickly get a shareable link that can be sent to any signer over the communication medium of your choice.
7. Custom domain & App Logo for Enterprise plan users
You can now display your own customized app logo from the console app for further branding and customization. In the console application under the preferences you can set your own sub domain and your logo. Note that the feature is available only to the subscribers of OpenSign Enterprise.
8. Enhanced User Profile
User profiles now include fields for company and job title, allowing for more detailed info. This information is automatically fetched when creating documents, so you don’t have to type it every time.
This addressed a major pain-point of the users of not being able to change the company name or job title if they miss-spelled it during sign-up.
9. Tour Messages
Enhancing user experience with tour messages in our application, in our continuous effort to improve user experience and make our application more user-friendly, this new feature is designed to guide users through various functionalities of the application, ensuring they can make the most out of our platform. We have made major improvements to the tour messages in v1.5.0 of [OpenSign](https://www.opensignlabs.com/).
10. API enhancements
The open APIs now supports all widget types, expanding the functionality and flexibility of the platform. This means you can create & sign documents as advanced as those in OpenSign from within your own application even without needing to log in to OpenSign via APIs.
11. Usage Analytics
The new functionality allows you to save and fetch usage analytics, giving you insights into how the app is being utilized. Some of the metrics available are Documents signed, Emails sent, Templates count, etc.
Future Enhancements
We are committed to continuously improving OpenSign based on user feedback and make it the world’s best [Open-Source](https://github.com/OpenSignLabs/OpenSign) document e-signature tool. The addition of above features is just the beginning, we plan to regularly update and enhance the platform aiming to revolutionize the way the world signs documents.

1,894,524 | How to Train Compute-Optimal Large Language Models? | Introduction Recently, an LLM with only 70B parameters outperforms GPT 3. This LLM, called... | 0 | 2024-06-20T09:29:42 | https://dev.to/novita_ai/how-to-train-compute-optimal-large-language-models-48cb | llm | ## Introduction
Recently, an LLM with only 70B parameters outperforms GPT 3. This LLM, called Chinchilla, was developed by Hoffmann and his colleagues. In their work, they state that [**current LLMs**](https://blogs.novita.ai/llm-leaderboard-2024-predictions-revealed/) are not compute-optimal. Why is this? How do they train their so-called compute optimal LLM Chinchilla? What are the limitations of their approach and how can we overcome these limitations? In this blog, we will look at these questions one by one.
## What Are Compute-Optimal Large Language Models?
The core idea behind a compute-optimal LLM is to strike the right balance between the model size (number of parameters) and the amount of training data used. This is in contrast to previous approaches that increased model size more aggressively than training data, resulting in models that were significantly undertrained relative to their capacity.
## What Are the Core features of a compute-optimal LLM?
### Feature 1: Balanced Scaling of Model Size and Training Data
Rather than scaling model size exponentially while only incrementally increasing the training data, compute-optimal LLMs increase both model size and training data in equal proportion. This ensures the model capacity is fully utilized by the available training data.
### Feature 2: Optimization for Overall Compute Efficiency
The goal is to find the sweet spot between model size and training data that delivers the best performance-per-compute. This allows maximizing the model's capability within a fixed computational budget, rather than simply pushing model size to new records.
### Feature 3: Less Computational Resources for Fine-Tuning and Inference
This further enhances their efficiency and real-world practicality, as deploying and using the model becomes more cost-effective.
## Aren't These Popular LLMs Not Compute-Optimal?
Sadly, according Hoffmann et al. (2022), these popular LLMs are not compute-optimal. Let's first go back to the ideas that impacted current LLMs.
### The Focus on the Model Size
Previous research by Kaplan et al. (2020) demonstrated a compelling power law relationship between language model size and performance. Specifically, they found that as the number of parameters in a model was increased exponentially, the model's performance on various benchmarks improved at a consistent power law rate.
This seminal work has had a profound impact on the field of large language models (LLMs), leading researchers and engineers to focus heavily on scaling up model size as the primary axis of improvement. The logic was clear - if performance scales so predictably with model size, then the path to better LLMs must be to simply build bigger and bigger models.
### Refocusing on the Amount of Training Data
Hoffmann et al. (2022) argue that this singular focus on model scaling has come at a significant cost. They posit that current state-of-the-art LLMs are in fact severely undertrained, with the research emphasis placed squarely on increasing model size rather than proportionally increasing the amount of training data.
This critique is a crucial contribution of their paper. The authors contend that the field has lost sight of the fundamental model-data trade-off, becoming preoccupied with pushing model size to new records without ensuring those models are trained on a commensurate amount of high-quality data. The result, they argue, is a situation where LLMs may have impressive parameter counts, but are ultimately suboptimal in their performance given the compute resources invested in their training.
By refocusing attention on this core trade-off between model capacity and training data, the authors set the stage for their empirical investigation into the truly optimal balance between these two key factors. Their findings, detailed in the following sections, offer a new paradigm for developing compute-efficient large language models.
## How to Train Compute-Optimal Large Language Models?
In this section, we will dive deeper into Hoffmann et al.'s (2022) paper titled "Training Compute-Optimal Large Language Models". As always, if research details sound too nerdy for you, just take this conclusion and skip this section: **for compute-optimal training, model size and number of training tokens should be scaled equally - for every doubling of model size, the number of training tokens should also double.**
### Empirically Estimating the Optimal Model-Data Trade-off
To investigate the optimal trade-off between model size and training data, the authors train over 400 models ranging from 70 million to 16 billion parameters, on datasets from 5 to 500 billion tokens. They model the final pre-training loss as a function of both model size and number of training tokens.
### Key Findings
The authors find that for compute-optimal training, model size and number of training tokens should be scaled equally - for every doubling of model size, the number of training tokens should also be doubled. This contrasts with the recommendations of Kaplan et al., who suggested a smaller increase in training tokens compared to model size.
### Training a Compute-Optimal Model: Chinchilla
Applying their findings, the authors train a 70 billion parameter model called Chinchilla, using the same compute budget as the 280 billion parameter Gopher model. Chinchilla significantly outperforms Gopher, GPT-3, Jurassic-1, and Megatron-Turing NLG on a wide range of downstream tasks, while also requiring substantially less compute for fine-tuning and inference.
### Concluding Remarks
The paper demonstrates that current large language models are significantly undertrained, and provides a principled approach to determining the optimal model size and training data for a given compute budget. This has important implications for the efficient development of future large-scale language models.
If you want to know more technical details, feel free to read the [original journal article](https://arxiv.org/abs/2203.15556).
## Limitations of the Approach of Training Compute-Optimal Large Language Models
Although the approach outlined in this article on compute-optimal large language models (LLMs) presents a compelling theoretical framework, there are a few potential limitations:
### Availability of Vast Training Data
- The principles rely on having access to extremely large, high-quality datasets to train the models.
- Acquiring and curating such massive datasets can be challenging, time-consuming, and costly.
- This may limit the ability to practically implement the approach, especially for smaller research teams or organizations.
### Hardware and Compute Constraints
- Training very large models with proportional amounts of data requires immense computational resources.
- Access to the necessary hardware (e.g. powerful GPUs, TPUs) and the required electricity/cooling infrastructure may be a limiting factor.
- The overall compute costs associated with this approach could be prohibitive for many.
### Domain-Specific Performance
- The article focuses on general-purpose language models, but the optimal balance of model size and training data may vary for models targeting specific domains or tasks.
- Certain applications may require a different trade-off approach to achieve the best results.
### Lack of Empirical Validation
- While the principles laid out are logically sound, the article does not provide empirical evidence or case studies demonstrating the efficacy of the compute-optimal approach.
- Further research and real-world implementation would be needed to validate the claims and quantify the benefits.
### Potential Societal Impacts
- Scaling up model size and training data could exacerbate concerns around AI safety, security, and the environmental impact of large-scale machine learning.
- These societal implications are not addressed in the article and would require careful consideration.
Overall, practical implementation of the compute-optimal LLM approach may face significant challenges related to data, hardware, domain-specificity, and broader impact considerations. Empirical evaluation and further research would be needed to fully assess its feasibility and benefits.
## An Alternative Way of Getting Better LLMs' Performances
While the compute-optimal approach outlined earlier presents a compelling framework for developing high-performing LLMs, there is an alternative solution that can offer even greater flexibility and efficiency: LLM APIs.
Instead of relying on a single, fixed LLM, [**Novita AI LLM API**](https://novita.ai/llm-api) provides access to a diverse range of language models, each with its own unique capabilities and areas of specialization. This allows users to select the most appropriate model for their specific needs.
Moreover, Novita AI Model API empowers users with the ability to easily adjust key model parameters, such as _top p_ (governs the model's word selection process to promote more diverse and meaningful text generation), _temperature_ (modulates the degree of randomness and exploration in the model's text production), _max tokens_ (constrains the length of the model's output) and _presence penalty_ (penalizes the model for excessive repetition of words, incentivizing it to generate more varied text). This level of customization enables fine-tuning the LLM's performance to match the unique requirements of each project or use case, resulting in more optimal and tailored results.
In addition to adjustable parameters, another standout features of Novita AI Model API is its support for system prompt input. Users can provide custom prompts or templates to guide the language model's behavior, allowing for more directed and purposeful responses. This can be particularly valuable for applications that require a specific tone, style, or domain-specific knowledge.
## Conclusion
The work by Hoffmann et al. represents a significant step towards optimizing the training of large language models within practical computational constraints. Their core idea of balancing model capacity and training data scale is both theoretically grounded and empirically validated through their Chinchilla model. By avoiding the pitfalls of severe undertraining, this compute-optimal approach unlocks new levels of performance and efficiency compared to prior state-of-the-art LLMs like GPT-3.
However, implementing such compute-optimal training at scale is not without challenges. Curating the staggeringly large high-quality datasets required poses difficulties. Availability of sufficient computational resources, from hardware to energy costs, may also hamper adoption - especially for smaller organizations. An alternative approach that provides more flexibility is to leverage advanced language model APIs like Novita AI Model API. These APIs give users access to a diverse range of pretrained models tailored for different use cases.

With Playwright, you can... | 0 | 2024-06-20T09:22:22 | https://dev.to/dutchskull/how-to-create-e2e-tests-for-react-using-playwright-4fgp | react, webdev, testing, playwright | Setting up end-to-end (E2E) tests for your project has never been easier. With Playwright, you can create robust tests that ensure your application works as expected across different browsers.
## Dependencies
To get started, you'll need:
- [Playwright](https://playwright.dev/docs/intro)
- [Playwright VS Code extension](https://marketplace.visualstudio.com/items?itemName=ms-playwright.playwright)
And for the documentation of playwright you can go [here](https://playwright.dev/docs/api/class-playwright)
## Setting Up Playwright
First, navigate to your React project directory and run:
```powershell
npm init playwright@latest
```
Follow the prompts to choose between TypeScript or JavaScript (the default is TypeScript). You'll also need to specify a name for your tests folder. I recommend using a `tests/e2e` folder at the root of your project.
You’ll be asked if you want to add a GitHub Actions workflow to run tests on CI. If you're using GitHub, this is a handy feature. However, I prefer GitLab and will show you how to set that up instead. Ensure you install Playwright browsers; otherwise, running your tests will be difficult.
After the setup, a configuration file will be generated. You'll need to update a few settings:
- Set `use > baseURL` and `webServer > url` to use `localhost` and the correct port for your React project.
- Update `testDir` to point to your `e2e` tests directory.
Here’s an example configuration:
```javascript
import { defineConfig, devices } from "@playwright/test";
export default defineConfig({
testDir: "./tests/e2e",
fullyParallel: true,
forbidOnly: !!process.env.CI,
retries: process.env.CI ? 2 : 0,
workers: process.env.CI ? 1 : undefined,
reporter: "html",
use: {
baseURL: "http://localhost:5173",
ignoreHTTPSErrors: true,
trace: "on-first-retry",
},
projects: [
{
name: "chromium",
use: { ...devices["Desktop Chrome"] },
},
{
name: "firefox",
use: { ...devices["Desktop Firefox"] },
},
{
name: "webkit",
use: { ...devices["Desktop Safari"] },
},
],
webServer: {
command: "npm run dev",
url: "http://localhost:5173",
reuseExistingServer: !process.env.CI,
},
});
```
## GitLab CI Configuration
Add the following task to your `.gitlab-ci.yml` file to run Playwright tests in your GitLab pipeline:
```yaml
run_playwright_tests:
stage: test
image: mcr.microsoft.com/playwright:v1.44.1-jammy
script:

```powershell
npx playwright codegen http://localhost:5173
```
This command opens a browser and a window that shows the code for the actions you perform in the browser. After clicking through your application to create your test, you can copy the generated code and add it to a `WHATEVER.spec.ts` file in your `tests/e2e` folder.
You can run your tests with:
```powershell
npx playwright test
```
## Creating Tests Using the VS Code Extension
If you prefer not to use the command line, you can use the [VS Code Playwright extension](https://marketplace.visualstudio.com/items?itemName=ms-playwright.playwright).
After installing the extension, navigate to the tests tab in VS Code. Click the `Record new` button at the bottom. Follow the same steps as in the terminal example, but this time the generated code will be automatically added to your project in a new test file.
With these steps, you’re ready to create and run E2E tests for your React project using Playwright. Happy testing!

Welcome back to another blog where I document the things I learned in web development. I do this because it helps retain the information and concepts as it is some sort of an active recall.
On days 57-59, after acquiring the DSA certificate from freeCodeCamp, I continued on to the next course which is the Front End Development Libraries.
The course teaches frameworks and libraries of CSS and Javascript. After learning Bootstrap, jQuery, and SASS. The course moves on to teach you about React and Redux and how the two work together in developing web apps.
Picking up from my last blog update, I was now able to complete the React and Redux course as well as finish taking notes of its syntax and concepts.
During the React course, I was able to learn about JSX elements, object oriented programming (OOP), class and functional components, using props, setting states, handling event listeners, CSS styling, initializing variables and methods, conditional statements (ternary and logical operators, if/else statements), and array iterations like filter and map to dynamically render elements.
During the Redux course, I was able to learn about action types, reducers, action creators, store, and connecting React + Redux using connect features and dispatch functions.
Having finished the courses, I admit that I have some knowledge gaps about React and Redux. As a constant learner, I'm pretty used to the feeling. And the only way to bridge those gaps and make the connections is actually utilizing the things I learned by applying it into building real projects.
I am pretty excited to do that and solidify the concepts I just learned.
As I want to further consolidate my knowledge in React + Redux, I plan to remake some of my favorite projects in the DSA course using said frameworks. This is to focus on their concepts and syntax by removing the need to create solutions and build algorithms since the mentioned projects were already complete.
For now, I'll stick to this plan, and in the future, when I think of new project ideas as well as being confident enough in React + Redux , I will build them from scratch using those frameworks.
Anyways, that’s all for now, more updates in my next blog! See you there! | thomascansino |
1,894,535 | What Are Web Beacons? Should I do something about them? | Should you do something about them? Well, let’s look at a 101 so we get more context! Web... | 0 | 2024-06-20T09:14:47 | https://dev.to/zoltan_fehervari_52b16d1d/what-are-web-beacons-should-i-do-something-about-them-4nai | webbeacons, webdev, website, pixels | Should you do something about them? Well, let’s look at a 101 so we get more context!
## Web Tracking 101: What Are Web Beacons?
Web beacons, also known as pixel tags or clear GIFs, are tiny, transparent images usually embedded in websites or emails. These beacons, often just 1x1 pixel in size, communicate with a server when the page or email is accessed. They collect data such as IP addresses, URLs, time of access, and browser types, providing insights into user behavior across different sites and devices.
## Looking Back: A Short History of Web Beacons
**The 1990s**
Web beacons emerged in the late 1990s as a solution for detailed tracking and analysis of online behavior. Unlike cookies, which had limitations in cross-site tracking, web beacons provided more comprehensive data collection.
**The 2000s to 2020s**
Over the decades, web beacons have evolved with technology, adapting to track user behavior across websites and mobile apps. With rising privacy concerns, regulations like the General Data Protection Regulation (GDPR) have been implemented to give users more control over their data, influencing how web beacons are used and disclosed.
## Cookies vs. Web Beacons
Cookies and web beacons serve similar purposes but function differently:
- Cookies: Small text files stored on a user’s device to retain preferences and browsing data. Users can view and manage them through browser settings.
- Web Beacons: Invisible images embedded in web content or emails that send data to servers when accessed. They are adept at cross-site and cross-platform tracking but are harder to block completely.
## Web Beacons In Practice: Where To Find Them
### Marketing
Marketers use web beacons extensively to monitor user behavior, track the effectiveness of email campaigns, and deliver personalized content.
### Law Enforcement
Authorities may use web beacons in cybercrime investigations to track illicit online activities.
### Academic Research
Researchers use web beacons to study online behavior, identify trends, and understand digital ecosystems, contributing to the improvement of online services.
## Pros & Cons of Web Beacons
### Pros
- Digital Marketing Insight: Track user journeys, time spent on pages, and email campaign effectiveness.
- Academic Research: Provide detailed data for studying internet usage patterns and online behavior.
- Personalized Online Experience: Enable businesses to offer more relevant content and advertisements.
### Cons
- Reputation Risk for Businesses: Overuse can damage brand image and user trust.
- Ethical Implications: Collecting data without explicit consent can attract scrutiny and ethical concerns.
- Privacy Concerns: Potential breaches of privacy due to their ability to monitor behavior covertly.
## Privacy and Web Beacons
Web beacons track online activity much like a digital breadcrumb trail, sending information about your device and behavior to servers. This can feel intrusive as it builds a detailed picture of your interests, habits, and preferences without your explicit consent.
## How to Filter Out Web Beacons
1. Inspect Source Code: Look for 1x1 pixel .gif files in a website’s source code.
2. Use Privacy Tools: Browser extensions like Privacy Badger and Ghostery can detect and notify you about web beacons.
## Web Beacons Are Almost Everywhere
A study by Princeton University found that nearly 80% of the internet’s most popular 1 million websites use [web beacons](https://bluebirdinternational.com/web-beacons/) or similar tracking technologies, highlighting their pervasive presence.
## How to Preserve Privacy Against Web Beacons
### 1. Use Privacy-Focused Browsers and Tools
Browsers like Firefox Focus, Brave, and DuckDuckGo come with built-in features to combat trackers. Extensions like Privacy Badger, Ghostery, and uBlock Origin enhance privacy protection.
### 2. Enable Do Not Track
Activate the “Do Not Track” option in your browser settings, though not all websites respect this request.
### 3. Disable Image Loading in Emails
Prevent automatic image loading to avoid hidden web beacons in emails.
### 4. Regularly Clear Cookies
Clearing cookies can disrupt tracking, reducing digital breadcrumbs.
### 5. Be Selective About Giving Out Your Email
Limit the number of marketing emails received, as they often contain web beacons. | zoltan_fehervari_52b16d1d |

## 1. Single Responsibility Principle (SRP)
> A class should have only one reason to change, meaning it should only have one job or responsibility.
```swift
// WRONG: A class that handles both user authentication and user data storage
class UserManager {
func authenticateUser(username: String, password: String) -> Bool {
// Authentication logic
return true
}
func saveUserDetails(user: User) {
// Save user details logic
}
}
// CORRECT: Separate classes for authentication and data storage
class Authenticator {
func authenticateUser(username: String, password: String) -> Bool {
// Authentication logic
return true
}
}
class UserStorage {
func saveUserDetails(user: User) {
// Save user details logic
}
}
```
## 2. Open/Closed Principle (OCP)
> Software entities should be open for extension but closed for modification.
```swift
// WRONG: A class that needs to be modified to support new types of notifications
class NotificationManager {
func sendNotification(type: String) {
if type == "email" {
// Send email notification
} else if type == "sms" {
// Send SMS notification
}
}
}
// CORRECT: Extendable notification types using protocol
protocol Notification {
func send()
}
class EmailNotification: Notification {
func send() {
// Send email notification
}
}
class SMSNotification: Notification {
func send() {
// Send SMS notification
}
}
class NotificationManager {
func sendNotification(notification: Notification) {
notification.send()
}
}
```
## 3. Liskov Substitution Principle (LSP)
> Subtypes must be substitutable for their base types without altering the correctness of the program.
```swift
// WRONG: A subclass that breaks the functionality of the superclass
class Bird {
func fly() {
print("Flying")
}
}
class Ostrich: Bird {
override func fly() {
// Ostrich can't fly, so this method should not exist here
fatalError("Ostriches can't fly!")
}
}
// CORRECT: Using protocol to define a contract for flying birds
protocol Flyable {
func fly()
}
class Sparrow: Flyable {
func fly() {
print("Flying")
}
}
class Ostrich {
// Ostrich does not conform to Flyable because it can't fly
}
```
## 4. Interface Segregation Principle (ISP)
> Clients should not be forced to depend on interfaces they do not use.
```swift
// WRONG: A single interface with too many responsibilities
protocol Worker {
func work()
func eat()
}
class Developer: Worker {
func work() {
// Coding
}
func eat() {
// Eating lunch
}
}
class Robot: Worker {
func work() {
// Coding
}
func eat() {
// Robots don't eat, so this method is not applicable
}
}
// CORRECT: Separate interfaces for different responsibilities
protocol Workable {
func work()
}
protocol Eatable {
func eat()
}
class Developer: Workable, Eatable {
func work() {
// Coding
}
func eat() {
// Eating lunch
}
}
class Robot: Workable {
func work() {
// Coding
}
}
```
## 5. Dependency Inversion Principle (DIP)
> High-level modules should not depend on low-level modules. Both should depend on abstractions.
```swift
// WRONG: High-level module depends on low-level module
class Database {
func save() {
// Save to database
}
}
class UserRepository {
private let database = Database()
func saveUser() {
database.save()
}
}
// CORRECT: High-level module depends on an abstraction
protocol Storage {
func save()
}
class Database: Storage {
func save() {
// Save to database
}
}
class UserRepository {
private let storage: Storage
init(storage: Storage) {
self.storage = storage
}
func saveUser() {
storage.save()
}
}
```

I don't know if I will develop Monica anymore in the future but let's hope this idea won't be stolen by anyone...please...readers...
Okay so basically this semester I teamed up again with Rifqy and Raihan because we are the team of Monica 2.0 in the previous semester. Shofi joined too in this semester because her team was splitted up due to her absence this semester because she was in South Korea for a student exchange program. In this semester, Software Development 2 subject was taught by three lecturers but we hardly got a class session on this subject.
We also barely touched this project. Seriously we didn't understand anything about API. Yes, we were required to make an API for the app. We couldn't use Firebase anymore and the API should be original. We even failed the sign in API. There was a time when we were asked to report our progress. Here's the report in a video.
[](http://www.youtube.com/watch?v=CKaxWh9lHzo)
There was also a time when we were asked to make a promotional poster and the poster would be rated by Digital Business students. Monica got the most comments from the Digital Business students LOL. I guess everyone needs this app huh? The slavery in the committees stays strong.
Today we had to present the app to the lecturers as the final score. We were lucky we got the early session so that there was only Mrs. Mira who assessed us. We could pass the presentation easily haha. Oh yeah as usual I linked the repository. [Go check this out!](https://github.com/realicejoanne/ppl2-project/) Well, it's not working so don't expect too much. | trianne24 |

Unlike ready-to-use software packages, custom software is just designed to satisfy specific needs and situations of the separate business. In this sense, the company can enjoy having software that is particularly fit to their workflows, processes as well as objectives.
## Why Choose Custom Software Development?
There are several reasons why businesses choose custom software development over off-the-shelf solutions: There are several reasons why businesses choose [custom software development](https://www.bigscal.com/custom-software-development-services/) over off-the-shelf solutions:
Tailored to Your Needs: Custom software is created in such a way that it will be able to perform the required task in the most precise and accurate way possible, which will help you avoid the hurdles that come with the integration into the already existing systems, that includes requests, reports, etc.
Scalability: An added advantage is the ease with which the custom software can be scaled as your business expands. This makes it possible to add new features and functionalities as the situation demands.
Greater Efficiency: Custom software is the best fit for your business and you will have fewer errors. This is because you will not have to duplicate tasks from different applications.
Competitive Advantage: Through software development that is flooded by custom solutions, you can attain a competitive advantage as compared with those who adopt generic software solutions.
## The Impact of Custom Software Development on Your Business
Custom software development can have a significant impact on your business in several ways:
## 1. Improved Efficiency
Custom software development offers one of the most important positive aspects, which is increased productivity. Making these tasks automatic and adding efficiency in the workplace for your processes using custom software can help you save time and resources. As such a tailored CRM system can, for instance, automate lead management, customer communication, and sales records, enabling your sales team to devote itself to the closing of deals, rather than administration affairs.
## 2. Better Customer Experience
Custom Applications can streamline the processes for your customers and you will be able to provide better service delivery and experience for them. By designing personalized software systems like mobile apps and web portals, your customers will be able to deal with your business in an enhanced, more convenient way.

## 4. Scalability
The scalability of tailored software stands out as one of the significant advantages. Common ready-made software products, in most cases, are developed according to the one-size-fits-all models and, therefore, their capabilities are limited in scaling as the business grows. If on the contrary, you decide to use custom software, scaling will be very simple and you will be able to make adjustments as the need arises for your business. Whether you require to supplement existing functions, support mass users, or integrate with other similar systems, custom software can be amended according to your changing needs.
## 5. Cost Savings
Although the price of individual custom software development may be more expensive than ready-to-use solutions, custom software programs control the costs of a business over time. By increasing process efficiency, promoting automatization, and eliminating the waste of time with manual operations custom software can help you spend resources and time in the right places. As a result, more resources are available for customized software to be developed without having to pay for license fees and ongoing subscriptions of the sales-off-the-shelf applications.

1,894,530 | Types of Transformer-Based Foundation Models | Transformer-based foundation models have revolutionized natural language processing (NLP) and are... | 0 | 2024-06-20T09:09:30 | https://victorleungtw.com/2024/06/20/transformer/ | nlp, transformers, autoencoders, autoregressive | Transformer-based foundation models have revolutionized natural language processing (NLP) and are categorized into three primary types: encoder-only, decoder-only, and encoder-decoder models. Each type is trained using a specific objective function and is suited for different types of generative tasks. Let’s dive deeper into each variant and understand their unique characteristics and applications.
## Encoder-Only Models (Autoencoders)
### Training Objective: Masked Language Modeling (MLM)
Encoder-only models, commonly referred to as autoencoders, are pretrained using masked language modeling. This technique involves randomly masking input tokens and training the model to predict these masked tokens. By doing so, the model learns to understand the context of a token based on both its preceding and succeeding tokens, which is often called a denoising objective.
### Characteristics
- **Bidirectional Representations**: Encoder-only models leverage bidirectional representations, enabling them to understand the full context of a token within a sentence.
- **Embedding Utilization**: The embeddings generated by these models are highly effective for tasks that require understanding of text semantics.
### Applications
- **Text Classification**: These models are particularly useful for text classification tasks where understanding the context and semantics of the text is crucial.
- **Semantic Similarity Search**: Encoder-only models can power advanced document-search algorithms that go beyond simple keyword matching, providing more accurate and relevant search results.
### Example: BERT
A well-known example of an encoder-only model is BERT (Bidirectional Encoder Representations from Transformers). BERT's ability to capture contextual information has made it a powerful tool for various NLP tasks, including sentiment analysis and named entity recognition.
## Decoder-Only Models (Autoregressive Models)
### Training Objective: Causal Language Modeling (CLM)
Decoder-only models, or autoregressive models, are pretrained using unidirectional causal language modeling. In this approach, the model predicts the next token in a sequence using only the preceding tokens, ensuring that each prediction is based solely on the information available up to that point.
### Characteristics
- **Unidirectional Representations**: These models generate text by predicting one token at a time, using previously generated tokens as context.
- **Generative Capabilities**: They are well-suited for generative tasks, producing coherent and contextually relevant text outputs.
### Applications
- **Text Generation**: Autoregressive models are the standard for tasks requiring text generation, such as chatbots and content creation.
- **Question-Answering**: These models excel in generating accurate and contextually appropriate answers to questions based on given prompts.
### Examples: GPT-3, Falcon, LLaMA
Prominent examples of decoder-only models include GPT-3, Falcon, and LLaMA. These models have gained widespread recognition for their ability to generate human-like text and perform a variety of NLP tasks with high proficiency.
## Encoder-Decoder Models (Sequence-to-Sequence Models)
### Training Objective: Span Corruption
Encoder-decoder models, often called sequence-to-sequence models, utilize both the encoder and decoder components of the Transformer architecture. A common pretraining objective for these models is span corruption, where consecutive spans of tokens are masked and the model is trained to reconstruct the original sequence.
### Characteristics
- **Dual Components**: These models use an encoder to process the input sequence and a decoder to generate the output sequence, making them highly versatile.
- **Contextual Understanding**: By leveraging both encoder and decoder, these models can effectively translate, summarize, and generate text.
### Applications
- **Translation**: Originally designed for translation tasks, sequence-to-sequence models excel in converting text from one language to another while preserving meaning and context.
- **Text Summarization**: These models are also highly effective in summarizing long texts into concise and informative summaries.
### Examples: T5, FLAN-T5
The T5 (Text-to-Text Transfer Transformer) model and its fine-tuned version, FLAN-T5, are well-known examples of encoder-decoder models. These models have been successfully applied to a wide range of generative language tasks, including translation, summarization, and question-answering.
## Summary
In conclusion, transformer-based foundation models are categorized into three distinct types, each with unique training objectives and applications:
1. **Encoder-Only Models (Autoencoding)**: Best suited for tasks like text classification and semantic similarity search, with BERT being a prime example.
2. **Decoder-Only Models (Autoregressive)**: Ideal for generative tasks such as text generation and question-answering, with examples including GPT-3, Falcon, and LLaMA.
3. **Encoder-Decoder Models (Sequence-to-Sequence)**: Versatile models excelling in translation and summarization tasks, represented by models like T5 and FLAN-T5.
Understanding the strengths and applications of each variant helps in selecting the appropriate model for specific NLP tasks, leveraging the full potential of transformer-based architectures.

1,894,527 | Why Coding Plagiarism Checkers are Essential For Developers | Ever written programs for hours and then wondered if your code is really original? Sometimes, it is... | 0 | 2024-06-20T09:07:16 | https://dev.to/codequiry/why-coding-plagiarism-checkers-are-essential-for-developers-1oco | webdev, codingplagiarismchecker, codeplagiarismchecker, codequiry | Ever written programs for hours and then wondered if your code is really original? Sometimes, it is easy to copy someone else's work in this fast-paced world of development. That's where the Coding Plagiarism Checker steps in. These intelligent tools scan your code against a database of millions of codes already available, helping one detect accidental plagiarism.
But why are coding plagiarism checkers so relevant? Well, other than simply not getting accused of plagiarism, they provide a surprisingly wide range of benefits for any level of developers. From protecting your own IP down to the security and quality of your code, this kind of plagiarism checker will do magic in your development workflow.
Now, let us understand a few important points regarding code plagiarism and how they can empower you to help you write better, more secure code.
## Understanding Code Plagiarism
Understanding code plagiarism is almost the same as searching for the verdict of whether or not, in any practical sense, someone has copied another individual's homework for coding. It literally means finding out whether the parts of a computer program are way too similar to another program without giving or achieving any kind of credit. This situation normally happens in events of code theft but also in instances when someone copies ideas and does not come to an agreement.
These similarities can be found with the help of [Java Code Plagiarism Checker](https://codequiry.com/resources/java-code-checker). They compare different pieces of code and find patterns that are too alike. This could include verification by teachers whether students are copying codes in the examination of their assignments or businesses checking the originality of their code.
## Role of Coding Plagiarism Checker
A Coding Plagiarism Checker is always likely to be a tool that assists in catching copying in computer code. You wouldn't want another student to copy your schoolwork, and programmers don't want their code copied. It can hunt through a bit of code and cross-compare it against millions of other codes online. If there are huge chunks that look way too similar, most probably, it could just be copying at work. This way, teachers can find out whether students have not done their work, and companies dealing in software protect their original ideas.
## Why Carry Out A Code Plagiarism Checker?
This will ensure creativeness in projects that concern coding.
This tool is an originality checker for your coding, rather like a spell-checker. The scanning is done to find copying in your code. This way, it ensures that the code is really yours and thus saves you from trouble, like mistakenly using other people's work without permission. It ensures that your project is yours alone and gets you the credit that should be given to you!
## Saves Time By Quickly Identifying Copied Code
Well, going through lines of code to search for copying would take ages! A Code Plagiarism Checker is much like a super fast scanner. Comparing your code with mountains of existing code in an instant underlines the copied parts. This saves you masses of time to focus on more important things, including debugging and building awesome new features.
## Helps Uphold Academic Integrity And Professional Ethics
Now, code plagiarism checkers are equivalent to spelling bees in the case of computer code. They will help you identify places where you might mistakenly have copied someone else's work without realizing it. This is important for schoolwork, to show that you learned the coding by yourself; in professional jobs, you don't want to take credit for some other person's ideas. It will help you as you go along to make sure all of your code is your own original work before you hand your projects in to ensure that you do not get into any trouble.
## Avoids Legal And Ethical Issues
You can refer to the [Code Checker Plagiarism](https://codequiry.com/code-plagiarism) as a companion who saves one from dishonesty.
Scanning your code for copied bits from other sources prevents one from submitting somebody else's work as their own. This is important because copying code without permission can be both a legal problem—for example, copyright theft—and an ethical one—not giving credit where it's due. The checker will keep you on the straight and narrow and avoid any kind of trouble down the line.
## Different Kinds of Users Who Use Coding Plagiarism Checkers Students
There are a few ways students can use coding plagiarism checkers.
Some honest students like to run their own work through these checkers prior to submitting assignments to try to pick up on anything they may have inadvertently copied from online sources. Others might use them to see how similar their code is to examples they find online that help them understand the concepts better. But some students might use them to try and cheat by copying code from somewhere else, hoping the checker won't pick it up.
## Professionals
It's used by many professionals, from programmers to check their codes for parts written before and probably forgotten, to make sure it's original. Essentially, anybody who wants to be certain that the Java code is from the person who claims to have written it will use a checker.
## Companies
Companies use coding plagiarism checkers much the same as tools used to check for copycats in writing. A company may be using one for a variety of reasons. Say the company wants to be certain that their programmers did not copy the code somewhere off the internet. This might be so that their own unique thoughts and ideas will be secure or so that they do not land in trouble by using the work of others.
## Final Thoughts
In a world where deadlines loom large and resources are spread thin, it's no wonder that plagiarism checking is a top item in your to-do list.
Now, imagine the [Coding Plagiarism Checker](https://codequiry.com/) as your superhero buddy!
It helps one to steer way clear of someone else's copied work, protecting the idea and ensuring cleanliness and efficiency in code. So what are you waiting for? This is one simple step that could save you a headache, trouble, and maybe even more trouble down the line. If you're looking to find assistance with a good code plagiarism checker, then we would necessitate that the best place you need to go is visiting Codequiry. It attracts a wiser way of preserving academic integrity. Visit today and learn more about it! | codequiry |

1,891,413 | A refresher on GitHub Pages | I moved my blog from WordPress to GitLab Pages in... 2016. I'm happy with the solution. However, I... | 0 | 2024-06-20T09:02:00 | https://blog.frankel.ch/refresher-github-pages/ | github, githubactions, githubpages | I moved my [blog](https://blog.frankel.ch/) from WordPress to [GitLab Pages](https://docs.gitlab.com/ee/user/project/pages/) in... 2016. I'm happy with the solution. However, I used [GitHub Pages](https://pages.github.com/) when I was teaching for both the courses and the exercises, _e.g._, [Java EE](https://formations.github.io/javaee/cours/servlet.html). At the time, there was no GitHub Actions: I used [Travis CI](https://www.travis-ci.com/) to build and deploy.
Recently, I had to use GitHub Pages to publish my [Apache APISIX workshop](https://nfrankel.github.io/apisix-workshop/). Travis is no longer free. GitHub Actions are a thing. I used the now nominal path and faced a few hurdles; here are my findings.
## GitHub Pages, at the time
The previous usage of GitHub Pages was pretty straightforward. You pushed to a specific branch, `gh-pages`. GitHub Pages rendered the root of the branch as a website.
Travis works by watching a `.travis.yml` build file at the repository root. When it detects a change, it runs it. I designed the [script](https://github.com/formations/javaee/blob/master/.travis.yml) to build HTML from Asciidoc sources and push it to the branch. Here's the significant bit:
```yaml
after_success:
# - ...
- git push --force --quiet "https://${GH_TOKEN}@${GH_REF}" master:gh-pages > /dev/null 2>&1
```
## GitHub Pages now
When you enable GitHub Pages, you can choose its source: GitHub Actions or Deploy from a branch. I used a workflow to generate HTML from Asciidoctor, and my mistake was selecting the first choice.
### GitHub Pages from a branch
If you choose Deploy from a branch, you can select the branch name and the source root folder. Apart from that, the behavior is similar to the pre-GitHub Action behavior. A vast difference, however, is that GitHub runs a GitHub Action after each push to the branch, whether the push happens via an Action or not.
While you can see the workflow executions, you cannot access its YAML source. By default, the `build` job in the workflow runs the following phases:
* Set up job
* Pull the Jekyll build page Action
* Checkout
* Build with Jekyll
* Upload artifact
* Post Checkout
* Complete job
Indeed, whether you want it or not, GitHub Pages builds for Jekyll! I don't want it because I generate HTML from Asciidoc. To prevent Jekyll build, you can put a `.nojekyll` file at the root of the Pages branch. With it, the phases are:
* Set up job
* Checkout
* Upload artifact
* Post Checkout
* Complete job
No more Jekyll!
### GitHub Pages from Actions
The `pages-build-deployment` Action above creates a `tar.gz` archive and uploads it to the Pages site. The alternative is to deploy *yourself* using a custom GitHub workflow. The GitHub Marketplace offers Actions to help you with it:
* [configure-github-pages](https://github.com/marketplace/actions/configure-github-pages): extracts various metadata about a site so that later actions can use them;
* [upload-pages-artifact](https://github.com/marketplace/actions/upload-github-pages-artifact): packages and uploads the GitHub Page artifact
* [deploy-pages](https://github.com/marketplace/actions/deploy-github-pages-site): deploys a Pages site previously uploaded as an artifact
The [documentation](https://docs.github.com/en/pages/getting-started-with-github-pages/using-custom-workflows-with-github-pages) does an excellent job of explaining how to use them across your custom workflow.
## Conclusion
Deploying to GitHub Pages offers two options: either from a branch or from a custom workflow. In the first case, you only have to push to the configured branch; GitHub will handle the internal mechanics to make it work via a provided workflow. You don't need to pay attention to the logs. The alternative is to create your custom workflow and assemble the provided GitHub Actions.
Once I understood the options, I made the first one work. It's good enough for me, and I don't need to care about GitHub Pages' internal workings.
**To go further:**
* [GitHub Pages](https://pages.github.com/)
* [Using custom workflows with GitHub Pages](https://docs.github.com/en/pages/getting-started-with-github-pages/using-custom-workflows-with-github-pages)
* [configure-github-pages Marketplace Action](https://github.com/marketplace/actions/configure-github-pages)
* [upload-pages-artifact Marketplace Action](https://github.com/marketplace/actions/upload-github-pages-artifact)
* [deploy-pages Marketplace Action](https://github.com/marketplace/actions/deploy-github-pages-site)

Advantages and Use Cases | Project management is a constantly evolving field that requires effective tools to track tasks,... | 0 | 2024-06-20T08:59:49 | https://dev.to/lenormor/why-choose-a-js-gantt-library-advantages-and-use-cases-58n3 | webdev, javascript, programming, learning | Project management is a constantly evolving field that requires effective tools to track tasks, deadlines, and resources. Among the various tools available, Gantt charts stand out for their ability to provide a clear and structured overview of project progress. With the advent of web technologies, JavaScript (JS) Gantt libraries have become a popular solution for integrating these charts into web applications. In this article, we will explore in depth why you should choose a JS Gantt library, detailing its advantages and providing concrete use cases. We will also lightly mention Schedule JS, a popular library in this domain.
## Advantages of JS Gantt Libraries
**1. Interactivity and Dynamism**
- JS Gantt libraries allow for the creation of interactive charts that respond to user actions in real-time. This dynamic interaction is crucial for modern project management, where rapid changes and updates are the norm. For instance, users can click on a task to view its details, drag and drop tasks to change their dates, or zoom in on a specific project period. This interactivity greatly facilitates the management and updating of schedules.
- Interactivity ensures that users are not just passive viewers but active participants in managing project timelines. This feature is particularly valuable for large teams where multiple stakeholders need to interact with the project plan. By allowing real-time adjustments, these libraries enable teams to adapt quickly to changes, making project management more fluid and responsive.
**2. Customization**
- JS Gantt libraries offer a high level of customization, enabling developers to tailor the charts to the specific needs of their project or organization. Customization options can include modifying the appearance to match corporate branding, adding custom data fields to track additional metrics, and integrating unique functionalities such as resource management or progress tracking.
- The ability to customize is essential for projects with unique requirements. For example, a construction project might need specific fields for materials and equipment, while a software development project might prioritize tracking code commits and testing phases. Customization ensures that the Gantt chart provides relevant and actionable insights, tailored to the specific context of the project.
**3. Real-Time Collaboration**
- Modern JS Gantt libraries often come with features that support real-time collaboration. Team members can work simultaneously on the same project schedule, with changes being reflected instantly for all users. This feature is particularly beneficial for remote teams or large projects requiring constant updates and communication.
- Real-time collaboration fosters a more integrated and cohesive work environment. It eliminates the delays associated with traditional project management methods, where updates had to be manually distributed. By ensuring that all team members have access to the most current information, these libraries help maintain alignment and prevent miscommunications.
**4. Integration with Other Tools**
- Many JS Gantt libraries are designed to integrate seamlessly with other project management tools and frameworks. For instance, they can be used in conjunction with popular frameworks like React, Angular, or Vue.js, and can easily pull data from APIs or databases.

let range: ClosedRange<T>
init(wrappedValue: T, range: ClosedRange<T>) {
self.range = range
self.value = range.clamping(wrappedValue)
}
var wrappedValue: T {
get { return value }
set { value = range.clamping(newValue) }
}
}
struct MyStruct {
@Clamp(range: 0...10) var clampedValue: Int = 5
}
```
#### 2.1.5. Function Builders
Swift 6.0 introduces function builders, allowing developers to customize the parsing and transformation process of expressions, creating more complex syntax structures.

```swift
struct ContentView: View {
var body: some View {
VStack {
Text("Hello, World!")
.font(.largeTitle)
Button("Tap me") {
print("Button tapped")
}
}
}
}
```

Traditional methods of testing will no longer suffice as software becomes more advanced. Test Automation was created with the advancement of technology to speed up the testing process by automating test cases and situations. In this blog, we will understand the difference between Selenium and Scriptless testing.
## What are Selenium and Scriptless Testing?
Scriptless testing refers to test automation that is performed without the use of a script or code. This sort of testing is commonly referred to as codeless testing.
Selenium is an open-source web browser automation tool. It provides a single interface for writing test scripts in various programming languages, including Ruby, Java, NodeJS, PHP, Perl, Python, and C#.
## Selenium Automation Testing
Selenium is a web browser automation technology that you can use on various platforms to automate browsers. Despite its extensive capabilities, its prime use is to automate web programs for testing purposes. It’s the foundation for a slew of other APIs, browser automation tools, and testing frameworks.
## Benefits of Selenium Automation Testing
Selenium runs on all kinds of browsers and operating systems, and you can control it using a variety of programming languages and frameworks. It can also automate time-consuming web-based administration operations.
It also allows for the creation of tests without the need to learn a test scripting language. Selenium also includes a test domain-specific language that you can use to write tests in Java, Ruby, C#, PHP, Python, and Perl, among other popular programming languages. After that, you can conduct the tests on the most recent and current web browsers.
Selenium is available for Windows, Mac OS X, and Linux. It is made up of various components that play a distinct role in developing web application test automation. Selenium Grid, Selenium IDE, Selenium WebDriver, and Selenium RC are the four tools available.
### Scriptless Automation Testing
The term “scriptless” refers to the absence of scripting and programming. This may be deceptive to the audience, particularly newcomers to software testing. Scriptless testing does not replace scripting and is incompatible with any test automation tool’s actual coding. It’s a very adaptable testing framework with very little code exposure.
In simple words, scriptless testing is a method of conducting testing without the need for scripts or coding in any programming language. It cuts the time it takes to create automated tests in half by reducing the amount of scripting required.

### Pros and Cons of Scriptless Automation Testing
Testers can design better automation scripts that illustrate the application’s essential functionality with scriptless Test Automation. The number of licenses for testing tools will undoubtedly come down as a result of this form of testing. Product development businesses, where they use the same resources for numerous activities, will find scriptless test automation more effective.
Despite their many benefits, scriptless test automation frameworks contain complicated underlying codes that you need to maintain and update on a regular basis. Those frameworks aren’t accessible; they have upfront and ongoing expenditures that exceed the cost of the instrument.
As a result, the only manual effort you require is to select the appropriate framework for your business needs. The testing team does not require any coding or scripting experience to generate automated tests using Scriptless Test Automation technologies. However, providing the flexibility to customize as a framework is an intelligent approach.
## Scriptless Testing vs Selenium: Features Comparison
Let us now compare the features of Selenium and Scriptless Testing.
To keep up with quality, Selenium must be built on long-term test automation. If the testing team wants to reuse test scripts, for example, they should utilize Selenium IDE. Selenium IDE is a Selenium component that allows you to record, edit, and debug functional test scripts. Because testers must create test scripts from scratch, they must be familiar with programming or scripting.
Scriptless Automation Tools, on the other hand, already include ready-to-use automated test cases and reusable code components. These functionalities are mostly available out-of-the-box in Scriptless Test Automation tools. Testers don’t need to have any programming or scripting experience. It gives testers and business users the ability to automate tests without having to bother about code. The Scriptless Test Automation tool has already taken care of the coding difficulty.
When it comes to debugging test scripts, Scriptless Test Automation tools minimize the need to continually debug scripted test code because the tool does it for you. In contrast, Selenium automation testers must manually debug test scripts when they find mistakes.
Selenium test environments are tough to set up. Selenium requires various plugins to facilitate Test Automation. Thus, system owners and administrators must manually update and configure everything. Scriptless test environments are easier to build and manage, allowing for a hassle-free upgrade process.
As a result, a Scriptless Test Automation solution is ideal for Agile and DevOps Test Automation.
## Why are Scriptless Automation Tools Better?
In general, Scriptless Test Automation Tools outperform Selenium. Scriptless test automation solutions are simple to set up and maintain, and unlike Selenium, they don’t require any plugins. It is much faster than Selenium in handling large numbers of test cases.
Scriptless Test Automation Tools don’t demand scripting or programming knowledge from their users. Users can conduct their QA operations using the platform’s “ready-to-use” test stages. Unlike Selenium, one must install Selenium IDE to use the playback tool, which provides users with a capability similar to the reusable codes scriptless provides. When it comes to scalability and flexibility, scriptless is the way to go. Everything you require is already on hand. Selenium, for the most part, necessitates the use of other components to use it properly.

1,894,500 | Why Can’t Robots Click The “I’m Not a Robot” Box On Websites? | Clicking a tiny box tells Google all they need to know about your humanity. By Safdar Ali If you’ve... | 0 | 2024-06-20T08:34:38 | https://dev.to/safdarali/why-cant-robots-click-the-im-not-a-robot-box-on-websites-2bo5 | webdev, programming, robots, recaptcha | Clicking a tiny box tells Google all they need to know about your humanity.
**By Safdar Ali**
If you’ve browsed the internet for any amount of time, you will likely come across a reCAPTCHA box. These boxes appear when you first enter certain websites and ask you to check a box to prove that you are not a robot. The box is labeled “I’m not a robot,” and everyone clicks without a second thought because they aren’t robots. Sometimes, clicking the box forces you to do a series of visual puzzles that ask you things like clicking on all of the images with a motorcycle in them or clicking on all of the pictures with streetlights in them. These basic tests lead people to believe that robots cannot do them. But that isn’t the case.
Online robots, or just “bots,” as they are often called, are highly advanced. They have been trained to do everything from playing Runescape to running entire X (formerly Twitter) account farms. So they can clearly click on a box or an image featuring a stop sign. The trick is that these tests aren’t determining whether or not you can click these things but how you click them.
## The Secret Behind reCAPTCHA
The way that reCAPTCHA boxes determine whether you are human or not is how slow and inefficient you are compared to a machine. Unlike bots, humans exhibit a natural delay and inconsistency when performing such tasks. Google’s reCAPTCHA uses this human touch to differentiate between bots and humans. Here’s how it works:
**Mouse Movements:** Humans tend to move the mouse in a slightly jerky and non-linear way, whereas bots can move with perfect precision and straight lines.
**Click Timing:** The timing of your clicks, including the slight delay between seeing the box and clicking it, varies naturally in humans but can be too uniform in bots.
**Behavior Analysis:** Google also monitors other user behaviors such as the time spent on the page, scrolling behavior, and how the user interacts with other elements before clicking the box.
## Why Bots Can’t Imitate Human Behavior
Bots are highly efficient and can perform repetitive tasks quickly and flawlessly, but this precision is exactly what gives them away. Mimicking human-like imperfections and randomness is incredibly complex. Despite advances in machine learning, creating a bot that can seamlessly blend in with human behavior on a consistent basis is a challenge.
## The Evolution of reCAPTCHA
Google’s reCAPTCHA has evolved significantly over the years:
**reCAPTCHA v1:** Initially, users had to type in text from distorted images, which was easy for humans but hard for bots.
**reCAPTCHA v2:** Introduced the “I’m not a robot” checkbox and image recognition tasks.
**reCAPTCHA v3:** Now, it runs in the background analyzing user behavior without disrupting the user experience.
## The Future of Bot Detection
As bots become more sophisticated, so does Google’s bot detection technology. Future versions of reCAPTCHA may rely more on passive behavior analysis and less on direct user interaction. This would make the process seamless and less intrusive while maintaining security.
## Conclusion
Clicking the “I’m not a robot” box is a simple action that tells Google a lot about your humanity. It’s not about whether you can click on an image of a streetlight; it’s about how you do it. This nuanced approach to bot detection ensures that while bots can replicate certain tasks, they still struggle to mimic the subtle imperfections of human behavior.
By understanding the intricacies of how reCAPTCHA works, we can appreciate the sophisticated measures in place to keep the internet secure and functional. As technology advances, so will the methods to ensure that humans and bots are correctly identified, maintaining a safer online environment for all users.
This comprehensive guide on why robots can’t click the “I’m not a robot” box is designed to provide you with a clear understanding of the technology and its future.
That's all for today.

1,894,375 | Database generated events: LiveSync’s database connector vs CDC | Ably LiveSync is a product we launched last month to help developers deliver live updates in their... | 0 | 2024-06-20T08:34:06 | https://ably.com/blog/livesync-database-connector-vs-cdc | database, dataengineering, architecture | [Ably LiveSync is a product we launched last month](https://hubs.la/Q02CzvQ20) to help developers deliver live updates in their applications by automatically keeping their database and frontend clients in sync.
[LiveSync](https://hubs.la/Q02CzvRD0) is made of two components, the [Models SDK](https://hubs.la/Q02CzvS_0) that runs on the client, and the [database connector ](https://hubs.la/Q02CzvSw0)that listens to changes in your database and syncs those changes to your clients.
When we talk about ‘listening to your database’, we’re often referring to Change Data Capture (or CDC). In CDC a component listens to your database and distributes events representing the changes that have happened. Normally the events that are created by CDC represent the changes to each individual underlying row.
**In this post, we’re going to discuss how the LiveSync database connector works, and how and why it is different from CDC.**
[Change data capture](https://en.wikipedia.org/wiki/Change_data_capture) (or CDC) is a mechanism of listening to the changes in your database and sharing these (typically over a queue) with other consumers. It allows other participants in your system to react to changes that have happened in one part of the system. A classic example is in some ‘event driven’ architecture where an email service will send a confirmation email when some e-commerce ‘order’ is created. Typically the changes that are shared as events by CDC represent changes to each individual underlying database table. For example, a change of email address for a user would have the user record’s ID, and email address before and after the change.
LiveSync’s database connector is different from traditional CDC, and we made some intentional choices about how and why it should be different. Our database connector is based on the ‘outbox pattern’, where a specific table is used to share database changes with the connector. Rows written to the outbox table have a ‘data’ field where the content of that column will be the payload of the event that’s generated and shared over Ably channels by the LiveSync database connector. The rows in the outbox also let you choose which Ably channel a record should be sent to.
So given both CDC and the LiveSync database connector generate events to be shared with some consumers, what’s the difference between the two? Well it’s all about encapsulation and control; two things we wanted to make sure LiveSync baked in, which you might not get with traditional CDC.
In traditional CDC:
- **Joins are hard:** Typically CDC events are generated per-table, this means that for any frontend data model that’s made of more than one database table, where you’d normally be writing a join in your database query, it’s really hard to work with in CDC. Events representing changes to two different tables have to be glued back together after they have been generated by a CDC system (perhaps using transaction ID metadata attached to the events).
- **Encapsulation is hard:** Because traditional CDC operates on the database table level, it’s far too easy to accidentally share some internal data model details with the consumers of your CDC events. Lots of CDC systems do allow you to filter the fields included in the CDC events, but it’s still an easy mistake to make.
- **Access control is hard:** It’s hard to encode into CDC which consumers should get access to which pieces of data. Typically all changes for a specific table go into a specific queue. Some CDC products do allow the partitioning of events into separate queues or topics based on a field of the changed row, but this isn’t always enough. Especially when you need data from a different table to enforce your access requirements (see: ‘joins are hard’). You end up having to create some filtering or mapping somewhere that can be queried server-side to work out if a client is allowed to see a row. (This is exactly what Supabase Realtime does, where the database has to be re-queried on each change event to enforce Row Level Security).
When we built the LiveSync database connector we wanted to make it easy to work with database generated events, and solve the things that made it hard to work with CDC. LiveSync is different firstly because it uses the ‘[outbox pattern](https://en.wikipedia.org/wiki/Inbox_and_outbox_pattern#The_outbox_pattern)’. Using the outbox table, you get to control the content of the events that are shared by the database connector. You also get to control which Ably channel those events are published on. These two differences solve a bunch of the problems with traditional CDC.
- **You can use channels to help with access control:** Ably’s [capabilities](https://hubs.la/Q02CzvWW0) mechanism allows you to authorise clients to only perform specific operations (publish, subscribe, etc) on specific [channels](https://hubs.la/Q02Czw6s0). This allows you to publish only the information relevant to those clients on those channels. And because you get to control the channel a database event is written to at the time the event is created, you can dynamically control which clients get access to which data.
- **You can expose only the data the clients need:** Because you get to specify the content of the event that’s written to an Ably channel, you can publish the exact content that the frontend needs. This solves the problems that CDC has with joining events from multiple tables, and solves the oversharing that can happen with CDC. So enforcing the right encapsulation and joins on the data is much easier.
Traditional CDC products can be faster to ‘plug and play’, as they will connect to your database without any changes to your application and start sharing database changes. But there’s a trade-off, enforcing the access control, encapsulation, and joins that your application needs is much harder.
In LiveSync we make these problems easy, by giving you an outbox table allowing you to choose which events are published, where those events are published, and the content those events carry. You can write events to the outbox transactionally along with the other changes in your database to ensure that the publish of messages to Ably and changes in your database either both happen, or neither happen. The outbox table along with the database connector guarantees that events written to the outbox table will appear in Ably, and will retain their order within each channel you’re writing to.

From aligning with business objectives and enhancing user experience to ensuring security and scalability, the platform on which a website is built plays a pivotal role in its success. This introduction explores the essential factors that businesses and developers should consider when selecting a web development platform, highlighting how this decision impacts every aspect of a website’s functionality and performance.
**Importance of choosing the right web development platform
Choosing the right web development platform is crucial for the success and effectiveness of your website. Here’s why it's so important:
Alignment with Business Goals: The platform you choose should align closely with your business objectives and goals. Whether you're creating a blog, an e-commerce site, a portfolio, or a corporate website, different platforms offer varying degrees of customization, scalability, and features that can either support or hinder your business objectives.
User Experience (UX): The platform significantly influences the user experience of your website. A well-chosen platform will provide intuitive navigation, fast load times, and responsive design, all of which contribute to a positive user experience. This, in turn, can lead to higher user engagement, lower bounce rates, and increased conversions.
**SEO Friendliness:** Search engine optimization (SEO) is critical for driving organic traffic to your website. Some platforms are built with SEO best practices in mind, offering features like clean code, customizable URLs, metadata management, and mobile responsiveness—all of which can positively impact your site’s search engine rankings.
Scalability:** As your business grows, your website needs to accommodate increased traffic, content, and functionality. Choosing a platform that is scalable allows you to easily expand your site’s capabilities without significant redevelopment. Scalability also ensures that your website remains fast and responsive as it grows.
**Security:** Websites are vulnerable to various cyber threats, including hacking and data breaches. A reputable web development platform often comes with built-in security features and regular updates to protect your website and its visitors' data. Choosing a platform with strong security measures can help mitigate these risks.
**Ease of Management:** The platform’s ease of use and management capabilities are crucial, especially if you or your team will be responsible for updating content, adding new features, or managing the website on a day-to-day basis. A user-friendly interface and robust content management system (CMS) can streamline these tasks and reduce maintenance overhead.
**Cost Effectiveness:** The initial setup costs, ongoing maintenance, and potential licensing fees associated with a web development platform should align with your budget and financial resources. Some platforms offer open-source options with no licensing costs, while others may require investment in premium themes, plugins, or hosting services.
**Community Support and Documentation:** A platform with a large and active community of developers, designers, and users provides access to a wealth of resources, including forums, documentation, tutorials, and plugins/extensions. This support network can be invaluable for troubleshooting issues, finding solutions, and staying updated with industry best practices.
**Comparing Popular Web Development Platforms

Artificial intelligence is making these... | 0 | 2024-06-20T08:28:12 | https://dev.to/otunkay/the-phishing-revolution-ai-powered-deception-makes-us-all-vulnerable-3d5g | Think you can spot a phishing email a mile away? Think again. Artificial intelligence is making these attacks more sophisticated and undetectable than ever before.
AI is being used to personalise phishing emails, crafting messages that appear to come from trusted sources and mimicking writing styles with uncanny accuracy. These emails can bypass traditional spam filters and exploit human emotions, tricking even the most vigilant users.
Recently, I conducted a training simulation where employees were presented with AI-generated phishing emails. The results were concerning – even tech-savvy individuals fell victim.
Here's the new reality: we can't solely rely on the ability to spot a suspicious email. Organisations need to go beyond traditional phishing awareness training. Consider implementing security awareness programs that leverage AI to simulate real-world attack scenarios. This will help employees develop a stronger sense of cyber resilience and be better prepared to identify and avoid these cunning attempts.
Is your organisation prepared for the next generation of phishing attacks? Let's discuss how AI-powered security awareness training can keep your employees safe.

I've recently taken on a task at my company to build an email template. Naively, you might think it would be simple. However, I quickly realized that HTML/CSS support in email clients is:
- Outdated
- Inconsistent from one client to another
I'm considering the idea of a cross-HTML/CSS compiler that transforms standard HTML/CSS into versions supported by various email clients. This would allow you to code as usual without worrying about client-specific rendering engines.
Would this be useful for you? | malo_legoff_29fbc05816bf |

### Question title
How to avoid the outline being blocked when hovering the pie chart sector in VChart?
### Problem description
The hover stroke of the pie chart sector is configured, but it will be obscured by other sectors
You can adjust the level of the element when hover, so that the hover element is always displayed above other sectors, which can avoid the problem of stroke obstruction

pie: {
state: {
hover: {
stroke: 'black',
lineWidth: 4,
zIndex: 1
}
}
},
```
### Code example
```javascript
const spec = {
type: 'pie',
data: [
{
id: 'id0',
values: [
{ type: 'oxygen', value: '46.60' },
{ type: 'silicon', value: '27.72' },
{ type: 'aluminum', value: '8.13' },
{ type: 'iron', value: '5' },

1,894,486 | The Rise of Ransomware 2.0: More Than Just Encryption | Imagine this: you wake up to a digital nightmare. Your entire company network is locked down, but... | 0 | 2024-06-20T08:21:47 | https://dev.to/otunkay/the-rise-of-ransomware-20-more-than-just-encryption-3o0l |
Imagine this: you wake up to a digital nightmare. Your entire company network is locked down, but there's no ransom note demanding Bitcoin. Instead, the attackers have unleashed your most sensitive data – customer records, financial reports, internal communications – onto the dark web. Welcome to the era of Ransomware 2.0, where data destruction is the new extortion tactic.
Ransomware has evolved beyond simple data encryption. Hackers now aim for complete annihilation, applying a "double extortion" strategy that puts immense pressure on organisations. They not only hold your data hostage, but also threaten to expose it publicly, creating a PR disaster alongside the data recovery challenge.
In my experience helping companies navigate this new reality, one thing is crystal clear: traditional backup and recovery plans are no longer sufficient. Organisations need a holistic security approach that includes Data Loss Prevention (DLP) to monitor and restrict sensitive data movement, network segmentation to isolate critical systems, and Continuous Threat Detection and Response (CTDR) to proactively identify and stop attacks before they escalate.
Don't wait to become a victim. Invest in advanced security solutions and train your employees to identify phishing attempts and social engineering tactics. Remember, prevention is always the smarter (and less stressful) option compared to cure.

# step-2: telling ESP32 where our sensor's data pin is connected
i2c = I2C(0, scl=Pin(22), sda=Pin(21))
oled_width = 128
oled_height = 64
oled = ssd1306.SSD1306_I2C(oled_width, oled_height, i2c)
# step-3: reading data continuously inside loop
while True:
try:
oled.text('Hello World!', 10, 10)
oled.show()
except OSError as e: # Error Handling
print("Error Data")
```
### Detailed Code Breakdown
1. **Importing Necessary Modules:**
```python
from machine import Pin, I2C
import ssd1306
```
- `from machine import Pin, I2C`: Imports the `Pin` and `I2C` classes from the `machine` module.
- `import ssd1306`: Imports the `ssd1306` module for OLED display control.
2. **Setting Up the I2
C Interface:**
```python
i2c = I2C(0, scl=Pin(22), sda=Pin(21))
```
- `i2c = I2C(0, scl=Pin(22), sda=Pin(21))`: Initializes the I2C interface on the ESP32 with GPIO 22 as the clock line and GPIO 21 as the data line.
3. **Setting Up the OLED Display:**
```python
oled_width = 128
oled_height = 64
oled = ssd1306.SSD1306_I2C(oled_width, oled_height, i2c)
```
- Initializes the OLED display with a width of 128 pixels and a height of 64 pixels using the I2C interface.
4. **Displaying Text on the OLED:**
```python
while True:
try:
oled.text('Hello World!', 10, 10)
oled.show()
except OSError as e:
print("Error Data")
```
- `while True`: Starts an infinite loop to continuously display data.
- `oled.text('Hello World!', 10, 10)`: Displays the text "Hello World!" at coordinates (10, 10) on the OLED.
- `oled.show()`: Updates the OLED display with the new data.
- `except OSError as e`: Catches any errors that occur during the display process and prints an error message.

1,894,480 | How to configure animations in VChart portfolio diagrams? | Question title How to configure animations for VChart's combo chart? Problem... | 0 | 2024-06-20T08:14:55 | https://dev.to/xuefei1313/how-to-configure-animations-in-vchart-portfolio-diagrams-4577 |
### Question title
How to configure animations for VChart's combo chart?
### Problem description
In a biaxial diagram, how to make the left and right axes execute the animation in order, and after the left axis column is executed, the right axis line will play the animation again?
Firstly, in VChart, its animation can be configured within each series. We can configure animations separately in columns and lines.
Then there is a dedicated configuration for outro animation in the series: animationAppear.
```typescript
animationAppear?: {
preset?: Preset | false;
duration?: number;
delay?: number;
easing?: EasingType;
oneByOne?: boolean;
};
```
We can configure delay on the online animation to start playing outro animation after the column completes the animation.
```javascript
series: [{
type: 'bar',
id: 'bar',
animationAppear: {
duration: 500
}
},
{
type: 'line',
id: 'line',
animationAppear: {
delay: 500,
}
}
]
```
In addition, if `oneByOne`is configured on the bar chart animation, it should be noted that the total animation duration of the bar chart = `x-axis number`* `duration`
### Code example
```javascript
const spec = {
type: 'common',
seriesField: 'color',
data: [
{
id: 'id0',
values: [
{ x: '周一', type: '早餐', y: 15 },
{ x: '周一', type: '午餐', y: 25 },
{ x: '周二', type: '早餐', y: 12 },

We will use two scripts: `hcsr04.py` (a module for the HC-SR04 sensor) and `main.py` (the main script to read and display distance measurements).
### hcsr04.py Module Code
This module handles the low-level operations of the HC-SR04 sensor. It initializes the trigger and echo pins, sends out ultrasonic pulses, and measures the time it takes for the echo to return. This time is then converted to distance.
```python
import machine, time
from machine import Pin
__version__ = '0.2.0'
__author__ = 'Roberto Sánchez'
__license__ = "Apache License 2.0. https://www.apache.org/licenses/LICENSE-2.0"
class HCSR04:

"""
self.echo_timeout_us = echo_timeout_us
# Init trigger pin (out)
self.trigger = Pin(trigger_pin, mode=Pin.OUT, pull=None)
self.trigger.value(0)
# Init echo pin (in)
self.echo = Pin(echo_pin, mode=Pin.IN, pull=None)

try:
pulse_time = machine.time_pulse_us(self.echo, 1, self.echo_timeout_us)
return pulse_time
except OSError as ex:
if ex.args[0] == 110: # 110 = ETIMEDOUT

mm = pulse_time * 100 // 582
return mm
def distance_cm(self):
"""

pulse_time = self._send_pulse_and_wait()
# To calculate the distance we get the pulse_time and divide it by 2

# the sound speed on air (343.2 m/s), that It's equivalent to
# 0.034320 cm/us that is 1cm each 29.1us
cms = (pulse_time / 2) / 29.1
return cms
```
### main.py Code
The main script imports the `HCSR04` class from the `hcsr04.py` module and uses it to continuously read and display distance measurements.
```python
# code written by Shemanto Sharkar (let's connect on LinkedIn: https://www.linkedin.com/in/shemanto/)
# step-1: importing necessary modules
from hcsr04 import HCSR04
from time import sleep
# step-2: telling ESP32 where our sensor's pins are connected
sensor = HCSR04(trigger_pin=5, echo_pin=18, echo_timeout_us=10000)
# step-3: reading data continuously inside loop
while True:
try:
distance = sensor.distance_cm()
print('Distance:', distance, 'cm')
sleep(1)
except OSError as e: # Error Handling
print("Error Data")
```
### Detailed Code Breakdown
1. **Importing Necessary Modules:**
```python
from hcsr04 import HCSR04
from time import sleep
```
- `from hcsr04 import HCSR04`: Imports the `HCSR04` class from the `hcsr04` module.
- `from time import sleep`: Imports the `sleep` function from the `time` module for introducing delays.
2. **Setting Up the Sensor:**
```python
sensor = HCSR04(trigger_pin=5, echo_pin=18, echo_timeout_us=10000)
```
- `sensor = HCSR04(trigger_pin=5, echo_pin=18, echo_timeout_us=10000)`: Initializes the HC-SR04 sensor with the trigger pin connected to GPIO 5 and the echo pin connected to GPIO 18. The `echo_timeout_us` parameter sets the timeout for listening to the echo signal.
3. **Reading Data Continuously:**
```python
while True:
try:
distance = sensor.distance_cm()
print('Distance:', distance, 'cm')
sleep(1)
except OSError as e:
print("Error Data")
```
- `while True`: Starts an infinite loop to continuously read data from the sensor.
- `distance = sensor.distance_cm()`: Reads the distance measurement from the sensor in centimeters.
- `print('Distance:', distance, 'cm')`: Prints the distance measurement to the console.
- `sleep(1)`: Introduces a delay of 1 second before the next reading.
- `except OSError as e`: Catches any errors that occur during the reading process and prints an error message.

## Top 10 Microservice Best Practices for Building Scalable Applications
By breaking down applications into smaller, independent services, organizations can achieve scalability, flexibility, and resilience. However, successfully implementing microservices requires following best practices to ensure the desired benefits.
Here are 10 essential Microservice best practices that can help you build scalable and resilient applications.
### 1\. Separate Data Store for Each Service
One of the fundamental principles of microservices is to maintain separate data stores for each service. This approach ensures that each microservice has control over its data and avoids tight coupling between services.
By using [**database-per-service pattern**](https://medium.com/@somasharma_81597/what-is-database-per-microservices-pattern-what-problem-does-it-solve-60b8c5478825) or distributed data management techniques, such as [event sourcing](https://medium.com/javarevisited/what-is-event-sourcing-design-pattern-in-microservices-architecture-how-does-it-work-b38c996d445a) or [CQRS](https://javarevisited.substack.com/p/how-cqrs-pattern-works-in-microservices), you can achieve data isolation and enhance scalability and resilience.
------
### 2\. Keep Code at a Similar Level of Maturity
Maintaining a consistent level of maturity across microservices is essential for a cohesive and maintainable architecture.
It is crucial to avoid situations where *some microservices are significantly more mature or advanced than others.*
By aligning the development progress and capabilities of microservices, you can avoid dependencies and simplify the overall [system design](https://medium.com/javarevisited/top-10-system-design-concepts-every-programmer-should-learn-54375d8557a6).
--------
### 3\. Separate Build for Each Microservice
To maintain the independence of microservices, it is essential to separate the build process for each service.
This practice enables individual teams to develop, test, and *deploy their microservices without impacting others*.
By **decoupling** the build and release processes, you can achieve faster iterations and reduce the risk of introducing bugs or regressions across the system.
-------
### 4\. Separate Repository for Each Microservice
Microservices should have their own code repositories to enable independent versioning, branching, and release management. Separate repositories facilitate decentralized development and deployment, allowing teams to work autonomously.
Each Microservice's repository should contain the code, configuration files, and deployment scripts specific to that service
-------
#### 5\. Deploy Using Containers (Docker)
**Containerization**, particularly with [*Docker*](https://medium.com/javarevisited/how-docker-works-internally-magic-behind-containerization-65ea5aa0a4ff), has become a popular choice for deploying microservices.
Containers provide lightweight and isolated runtime environments that encapsulate microservice dependencies and configurations.
By packaging microservices into containers, you can achieve consistent deployment across different environments, simplify scaling, and improve portability.
[](https://medium.com/javarevisited/how-docker-works-internally-magic-behind-containerization-65ea5aa0a4ff)
------
### 6\. Stateless Design (Treat Server as Stateless)
Adopting a stateless design for microservices helps improve scalability and resilience. Each microservice should treat the server as stateless, meaning it does not store session-specific data.
Instead, it relies on external services or databases to maintain state if required. Stateless services can be easily [scaled horizontally](https://medium.com/javarevisited/what-is-horizontal-and-vertical-scaling-in-system-design-scale-out-vs-scale-up-eb265026d51d) to handle increased traffic and provide fault tolerance and load balancing.
This is also one of the most important lesson I learned in my software development career, always choose Stateless and keep it stateless as long as you can.
------
### 7\. Domain-Driven Design
Domain-driven design (DDD) is a software development approach that aligns business requirements with the software architecture.
By organizing microservices around specific domains or business capabilities, you can achieve a more cohesive and maintainable system. DDD emphasizes the modeling of business entities, aggregates, and bounded contexts, ensuring that microservices are closely aligned with business needs.
------
### 8\. Micro Frontend
Micro frontend architecture extends the [principles of microservices](https://medium.com/javarevisited/10-microservices-design-principles-every-developer-should-know-44f2f69e960f?postPublishedType=repub) to the frontend layer.
It involves breaking down the user interface into smaller, self-contained modules that can be developed and deployed independently.
By adopting micro frontend, you can achieve frontend scalability, independent deployment, and improved user experience through modular and reusable components.
------
### 9\. Single Responsibility
Applying the **single responsibility principle** to microservices ensures that each service has a specific and well-defined purpose. Each microservice should focus on a particular business capability or functionality.
This practice enhances modularity and allows for independent development, testing, and deployment. Avoid creating monolithic services that handle multiple responsibilities, as it can lead to tightly coupled and complex architectures.
-------
### 10\. Loose Coupling and High Cohesion
Microservices should be loosely coupled, meaning they can operate independently without strong dependencies on other services. Loose coupling allows for independent scaling, deployment, and modification of services.
Additionally, strive for high cohesion within each microservice, ensuring that its components are closely related and work together to fulfill a single purpose.
Well-defined APIs, contracts, and communication protocols are key to achieving loose coupling and high cohesion.
------
### 11\. Use Kubernetes for Scaling [Bonus]
This is a bonus best practice for you because you have read the article till the end. [Kubernetes](https://medium.com/javarevisited/how-does-kubernetes-work-internally-702b5d16c6ef) is a powerful container orchestration platform that simplifies the management and scaling of microservices.
It provides features like automatic scaling, load balancing, service discovery, and self-healing capabilities.
By leveraging Kubernetes, you can dynamically scale your microservices based on resource usage, distribute traffic efficiently, and ensure high availability and fault tolerance.

1,894,471 | Unit Testing: Why It Matters and How to Do It Effectively in Python | Introduction Unit testing is a critical aspect of software development that ensures... | 0 | 2024-06-20T08:00:40 | https://dev.to/manavcodaty/unit-testing-why-it-matters-and-how-to-do-it-effectively-in-python-g65 | bug, programming, python | # Introduction
Unit testing is a critical aspect of software development that ensures individual components of a program work as intended. It helps identify bugs early, facilitates maintenance, and improves code quality. This blog post will delve into why unit testing is important and how to implement it effectively in Python.
---
## Why Unit Testing Matters
## Early Bug Detection
Unit testing allows developers to detect and fix bugs early in the development process. By isolating each unit (a function or method) and testing it independently, you can identify issues before they propagate through the entire system. This early detection can save significant time and effort, reducing the cost of debugging later.
---
### Code Quality and Maintainability
High-quality code is easier to maintain, extend, and refactor. Unit tests serve as a form of documentation, providing insight into how individual units are expected to behave. This clarity helps developers understand the codebase, facilitating smoother transitions when new team members join or when the project evolves.
---
### Confidence in Code Changes
Unit tests provide a safety net that gives developers confidence when making changes to the code. If a change causes a test to fail, it’s a clear indication that something has gone wrong. This feedback loop ensures that new features or bug fixes do not inadvertently break existing functionality.
---
## How to Do Unit Testing Effectively in Python
### Choosing a Testing Framework
Python offers several testing frameworks, but `unittest` and `pytest` are among the most popular.
- **unittest**: This is Python's built-in testing framework, inspired by Java's JUnit. It provides a solid foundation for creating and running tests.
- **pytest**: This is a third-party framework that is highly flexible and user-friendly. It supports fixtures, parameterized testing, and has an extensive plugin ecosystem.
---
### Writing Your First Test with `unittest`
Let's start with a simple example using `unittest`. Suppose we have a function that adds two numbers:
```python
def add(a, b):
return a + b
```
To test this function, create a new test file `test_math.py`:
```python
import unittest
from your_module import add
class TestMath(unittest.TestCase):
def test_add(self):
self.assertEqual(add(1, 2), 3)
self.assertEqual(add(-1, 1), 0)
self.assertEqual(add(0, 0), 0)
if __name__ == '__main__':
unittest.main()
```
Run the test using the command:
```bash
python -m unittest test_math.py
```
---
### Writing Your First Test with `pytest`
Now, let's achieve the same goal using `pytest`. Install `pytest` if you haven't already:
```bash
pip install pytest
```
Create the same test in `test_math.py`:
```python
from your_module import add
def test_add():
assert add(1, 2) == 3
assert add(-1, 1) == 0
assert add(0, 0) == 0
```
Run the test with the command:
```bash
pytest
```
---
### Best Practices for Effective Unit Testing
### 1. **Isolate Tests**
Ensure that your tests are independent and do not rely on external states or side effects. This isolation helps pinpoint the source of any failure and makes your tests more reliable.
### 2. **Write Clear and Concise Tests**
Tests should be easy to read and understand. Use descriptive names for your test functions and variables. Clear tests are easier to maintain and serve as documentation for your code.
### 3. **Test Edge Cases and Error Conditions**
While it's essential to test normal scenarios, also consider edge cases and potential error conditions. This comprehensive testing approach ensures your code handles unexpected inputs gracefully.
### 4. **Use Fixtures and Mocks**
Fixtures and mocks help set up necessary conditions for your tests without repeating setup code. `pytest` fixtures and the `unittest.mock` module are powerful tools that make your tests cleaner and more maintainable.
### 5. **Run Tests Frequently**
Incorporate unit tests into your development workflow. Run tests frequently, especially before committing code changes. Continuous Integration (CI) tools can automate this process, ensuring that tests run with every code update.
---
## Conclusion
Unit testing is a cornerstone of robust software development. It ensures code quality, facilitates maintenance, and provides confidence in code changes. By choosing the right framework and following best practices, you can write effective unit tests that make your Python projects more reliable and maintainable. Start integrating unit tests into your development process today and experience the benefits of well-tested code. | manavcodaty |

1,854,003 | Forget your database exists! Leave it to Metis | As developers, we all strive to keep our systems in shape. We maintain them, we review metrics and... | 0 | 2024-06-20T08:00:00 | https://www.metisdata.io/blog/forget-your-databases-exist-leave-it-to-metis | sql, database, monitoring | As developers, we all strive to keep our systems in shape. We maintain them, we review metrics and logs, and we react to alerts. We do whatever it takes to make sure that our systems do not break, especially databases that are crucial to our applications. Wouldn’t it be great if there was no need to do the maintenance at all? Would you like to just have tools that could take care of your databases and let you forget that they exist altogether? Read on how to do that.
## Hardships of Database Maintenance
As developers in today's world, we need to maintain our databases. We need to fix performance issues, maintain indexes, and perform routine maintenance tasks. This takes time and slows us down. This also impacts everything we do - the way we review our code, we run our CI/CD pipelines, or we deploy the software
One thing that can make our lives much easier when it comes to the services we are building is **continuous database reliability**. We would like to know whenever things break in our databases without going and checking explicitly. What’s more, we’d like all the issues to be fixed automatically. We would like to sleep well and not worry about on-call duties, maintenance tasks, or scaling. Our tools must **support us in** [**maintaining the databases**](https://www.metisdata.io/blog/the-three-pillars-of-successful-database-maintenance-and-monitoring).
Most industry solutions don’t give us that. They swamp us with raw infrastructure metrics, manually curated alerts, or detailed dashboards that blink green and red but don’t give any answers. We need something better. We need tools that can run anomaly detection, tune the alarms automatically, identify weekly patterns, understand database-focused metrics, and fix issues automatically. We should be alerted only when the issues can’t be solved automatically. We shouldn’t think about databases at all and most of the problems should be avoided or solved by the tools without intervention from our end.
**Recommended reading:** [**All Your Monitoring Solutions Are Wrong, Here's Why**](https://www.metisdata.io/blog/all-your-monitoring-solutions-are-just-wrong)
[Metis](https://www.metisdata.io/) gives us exactly that and we can completely forget about the databases. Metis understands database-focused signals, detects anomalies, identifies patterns, reviews configurations and extensions, and alerts us only when issues need to be solved outside of database and deployment levels.

#### Introduction
In this tutorial, we will learn how to interface a DHT22 temperature and humidity sensor with an ESP32 microcontroller using MicroPython. The DHT22 is a reliable sensor for measuring temperature and humidity, making it perfect for environmental monitoring projects.
#### Prerequisites
Before we dive into the code, ensure you have the following:
- ESP32 microcontroller
- DHT22 sensor
- Breadboard and jumper wires
- MicroPython installed on the ESP32
- Thonny IDE or any other suitable IDE for writing and uploading MicroPython code
#### Code Explanation
Here is the complete code to read temperature and humidity from the DHT22 sensor and print the values to the console:
```python
# code written by Shemanto Sharkar (let's connect on LinkedIn: https://www.linkedin.com/in/shemanto/)
# step-1: importing necessary modules
from machine import Pin
from utime import sleep
import dht
# step-2: telling ESP32 where our sensor's data pin is connected
sensor = dht.DHT22(Pin(13))
# step-3: reading data continuously inside loop
while True:
try:
sensor.measure()
t = sensor.temperature()
h = sensor.humidity()
print("temp=" + str(t))
print("humidity=" + str(h))
sleep(2)
print("")
except OSError as e: # Error Handling
print("Error Data")
```
#### Detailed Code Breakdown
1. **Importing Necessary Modules:**
```python
from machine import Pin
from utime import sleep
import dht
```
- `from machine import Pin`: Imports the `Pin` class from the `machine` module, used for configuring GPIO pins.
- `from utime import sleep`: Imports the `sleep` function from the `utime` module for introducing delays.
- `import dht`: Imports the DHT library to interact with the DHT22 sensor.
2. **Setting Up the Sensor:**
```python
sensor = dht.DHT22(Pin(13))
```
- `sensor = dht.DHT22(Pin(13))`: Initializes the DHT22 sensor on GPIO pin 13. This line tells the ESP32 where the sensor's data pin is connected.
3. **Reading Data Continuously:**
```python
while True:
try:
sensor.measure()
t = sensor.temperature()
h = sensor.humidity()
print("temp=" + str(t))
print("humidity=" + str(h))
sleep(2)
print("")
except OSError as e:
print("Error Data")
```
- `while True`: Starts an infinite loop to continuously read data from the sensor.
- `sensor.measure()`: Triggers the sensor to measure temperature and humidity.
- `t = sensor.temperature()`: Reads the temperature value from the sensor.
- `h = sensor.humidity()`: Reads the humidity value from the sensor.
- `print("temp=" + str(t))`: Prints the temperature value to the console.
- `print("humidity=" + str(h))`: Prints the humidity value to the console.
- `sleep(2)`: Introduces a delay of 2 seconds before the next reading.
- `except OSError as e`: Catches any errors that occur during the reading process and prints an error message.

Automating this task with PowerShell can save you time and hassle.
## The Solution
PowerShell has cmdlets that can help you identify and stop processes. We will use `Get-NetTCPConnection` to find the process ID (PID) using the port and `Stop-Process` to terminate the process.
### Step-by-Step Guide
### 1. Define the Function
We will create a function called `Kill-PortProcess` that takes a port number as a parameter and kills the process using that port.
```powershell
function Kill-PortProcess {
param (
[int]$Port
)
try {
$processId = (Get-NetTCPConnection -LocalPort $Port | Select-Object -ExpandProperty OwningProcess)
if ($processId) {
Stop-Process -Id $processId -Force
Write-Host "Process with ID $processId that was using port $Port has been terminated."
} else {
Write-Host "No process is using port $Port."
}
} catch {
Write-Host "An error occurred: $_"
}
}
```
### 2. Save the Function
To make this function available in all your PowerShell sessions, save it in your PowerShell profile script. You can edit your profile script by running:
```powershell
code $PROFILE
```
Copy and paste the function definition into your profile script and save the file.
### 3. Use the Function
Now you can use this function in any PowerShell session. For example, to kill the process using port 8080, you would run:
```powershell
Kill-PortProcess -Port 8080
```
### Conclusion
With this custom PowerShell function, you can quickly and easily free up ports by terminating the processes that are using them. This can be particularly useful for developers and system administrators who frequently run into port conflicts.
Feel free to customize the function to better suit your needs, and happy scripting!

1,894,465 | Deploy helm charts with go lang | What is Helm ? Helm is designed to simplify the deployment and management of complex application... | 0 | 2024-06-20T07:55:37 | https://medium.com/@varunrathod0045/deploy-helm-charts-with-go-lang-fa3b967af124 | go, helm, kubernetes | > **What is Helm ?**
Helm is designed to simplify the deployment and management of complex application workloads in Kubernetes. It functions similarly to a package manager for Kubernetes, where the packages are known as Helm Charts. A Helm Chart combines a template file, which outlines the Kubernetes resources to be deployed, and a values file that provides the necessary configuration for the template. The templating system in Helm Charts allows for package reusability.
> **The Helm go SDK ?**
Helm includes a convenient CLI, a robust command-line tool that helps end-users manage all stages of a Chart’s lifecycle. However, using the CLI for programmatically installing Helm Charts on a Kubernetes cluster is not ideal for building a reliable and predictable application. Fortunately, the Helm developers designed the CLI as an interface for the [Go SDK](https://github.com/mittwald/go-helm-client), which I will use for this purpose.
> **Installing and Using Helm client ….**
First we need to install go-helm-client, we can use below command and it will add this module into `go.mod` file.
```sh
$ go get github.com/mittwald/go-helm-client
```
Now we can import this like `helmcilent "github.com/mittwald/go-helm-client"` and use this in our application.
```go
package main
import (
"fmt"
"os"
helmclient "github.com/mittwald/go-helm-client"
)
func GetHelmClient(kubeConfig string, namespace string) (helmclient.Client) {
opt := &helmclient.KubeConfClientOptions{
Options: &helmclient.Options{
Namespace: namespace, // Change this to the namespace you wish to install the chart in.
RepositoryCache: "/tmp/.helmcache",
RepositoryConfig: "/tmp/.helmrepo",
Debug: true,
},
KubeContext: "",
KubeConfig: []byte(kubeConfig),
}
helmClient, err := helmclient.NewClientFromKubeConf(opt)
if err != nil {
fmt.Printf("Failed to initialize Helm Client: %v", err)
return nil
}
return helmClient
}
func main() {
dirname, err := os.UserHomeDir()
kubeConfig, err := os.ReadFile(fmt.Sprintf("%s/.kube/config", dirname))
if err != nil {
t.Fatalf("Not able to read File: %v", err)
}
helmClient := helmc.GetHelmClient(string(kubeConfig), "default")
}
```
you can run and test this on your local Kubernetes if your [docker-kubernetes](https://docs.docker.com/desktop/kubernetes/) is enabled. providing `kubeConfig` and `namespace` you can create helmClient object and using that you can perform helm operations.
Here are **list of methods** that you are able to call using this client.
```go
type Client interface {
AddOrUpdateChartRepo(entry repo.Entry) error
UpdateChartRepos() error
InstallOrUpgradeChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions) (*release.Release, error)
InstallChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions) (*release.Release, error)
UpgradeChart(ctx context.Context, spec *ChartSpec, opts *GenericHelmOptions) (*release.Release, error)
ListDeployedReleases() ([]*release.Release, error)
ListReleasesByStateMask(action.ListStates) ([]*release.Release, error)
GetRelease(name string) (*release.Release, error)
// RollBack is an interface to abstract a rollback action.
RollBack
GetReleaseValues(name string, allValues bool) (map[string]interface{}, error)
GetSettings() *cli.EnvSettings
GetProviders() getter.Providers
UninstallRelease(spec *ChartSpec) error
UninstallReleaseByName(name string) error
TemplateChart(spec *ChartSpec, options *HelmTemplateOptions) ([]byte, error)
LintChart(spec *ChartSpec) error
SetDebugLog(debugLog action.DebugLog)
ListReleaseHistory(name string, max int) ([]*release.Release, error)
GetChart(chartName string, chartPathOptions *action.ChartPathOptions) (*chart.Chart, string, error)
RunChartTests(releaseName string) (bool, error)
}
```
Let me give you an example how you can use the helmClient and installChart from local directory.
```go
import (
"context"
)
func main() {
// using old helmClient that we have created before
helmClient := helmc.GetHelmClient(string(kubeConfig), "default")
// Define the chart to be installed
chartSpec := ChartSpec{
ReleaseName: "nginx",
ChartName: "/tmp/nginx",
Namespace: "default",
UpgradeCRDs: true,
Wait: true,
}
// Install a chart release.
// Note that helmclient.Options.Namespace should ideally match
// the namespace in chartSpec.Namespace.
if _, err := helmClient.InstallChart(context.Background(), &chartSpec,
nil); err != nil {
panic(err)
}
}
```
You can also provide a zip or link to zip file as value in `ChartName `.
If you want more example you can look into this. [https://github.com/mittwald/go-helm-client/blob/v0.12.9/client_test.go](https://github.com/mittwald/go-helm-client/blob/v0.12.9/client_test.go)

1,894,321 | Understanding IQueryable<T> in C# | Hi There! 👋🏻 You've probably used IEnumerable<T>, and most certainly used... | 0 | 2024-06-20T07:53:35 | https://dev.to/rasheedmozaffar/understanding-iqueryable-in-c-4n37 | csharp, dotnet, learning, database | ## Hi There! 👋🏻
You've probably used `IEnumerable<T>`, and most certainly used `List<T>` if you've coded in C# before. These two are very popular and are often presented early to you when you're learning the language. But have you heard of `IQueryable<T>`? This one is a little more advanced, but it's got so much power that you should know about, so you can make good use of it.
Ladies and gents, we're going on a journey to demystify the `IQueryable` interface, so... Grab a coffee and let's get started! ☕️
## What's `IQuyerable<T>`? 🤔
The `IQueryable` interface is a cornerstone of LINQ, one of C#'s most powerful features. This interface is specifically designed for querying data from various sources that implement `IQueryable<T>`, such as SQL databases or in-memory collections like `List<T>`. What sets `IQueryable` apart are its compelling features that make it versatile and efficient for data querying.
Let's begin by highlighting the features of this interface that do give it this speciality and uniqueness.
## 1: Deferred execution 🦥
Deferred execution, which happens to be a feature of `IEnumerable`, also inherited by `IQueryable`, is in simple words, delaying the execution of the query until the data is actually needed. Didn't click? Keep reading.
Let's look at this basic code snippet, to see what deferred execution means in a more hands-on way:
```csharp
List<FamousPerson> famousPeople =
[
new FamousPerson(1, "Sandy Cheeks", false),
new FamousPerson(2, "Tony Stark", true),
new FamousPerson(3, "Captain Marvel", true),
new FamousPerson(4, "Captain America", true),
new FamousPerson(5, "SpongeBob SquarePants", false),
new FamousPerson(6, "Hulk", false)
];
IQueryable<FamousPerson> famousAndCanFly = famousPeople
.AsQueryable()
.Where(x => x.CanFly);
foreach (var fp in famousAndCanFly)
{
Console.WriteLine($"{fp.Name} can FLY!");
}
record FamousPerson(int Id, string Name, bool CanFly);
```
I want you to copy the code, and use the debugger to see what the value of `famousAndCanFly` evaluates to. You might think it'll be a collection of 3 people, but actually it's not. You will see that the value doesn't carry any data, but once you step inside the `foreach` loop, the results are carried out. This is simply what deferred execution means, the execution is delayed until the data is actually needed (i.e the enumerating of the query results inside the `foreach` loop).
## 2: Expression trees 🌳
I've chained some additional query filters to the previous query, so now it looks like this:
```csharp
IQueryable<FamousPerson> famousAndCanFly = famousPeople
.AsQueryable()
.Where(x => x.CanFly);
famousAndCanFly = famousAndCanFly
.Where(x => x.Id < 3);
famousAndCanFly = famousAndCanFly.
Where(x => x.Name.Contains("s", StringComparison.OrdinalIgnoreCase));
Console.WriteLine(famousAndCanFly.Expression);
```
It's just basic LINQ extension method calls here, but the thing to note is, the console log on the last line. What is the `Expression` property of `IQueryable`? This is basically a tree of expressions, which `IQueryable` puts together as you compose the query. It allows the data source provider, to grab the query expression tree, and translate it into something that can be used against that data source. For that reason, the data source provider has to provide an implementation for `IQueryable`.
If you were to run the previous code, it'd print something like this:
`System.Collections.Generic.List1[FamousPerson].Where(x => x.CanFly).Where(x => (x.Id < 3)).Where(x => x.Name.Contains("s", OrdinalIgnoreCase))`
See, it's just a bunch of chained query expressions and where statements, which here in our case, the data source happens to be an in memory collection, and since it implements `IQueryable`, you can bet that it knows how to properly translate that into something the in-memory collection can understand.
## Examples of `IQueryable` Functionality
I said earlier that `IQueryable` is a part of `System.Linq` namespace, and everything LINQ you can do with other collections, can be done on this interface too. From using `Where`, `OrderBy`, `Select` and literally anything else, you can keep on chaining method calls to compose the most complex query you could ever imagine. You're literally just confined by how much LINQ you know.
```csharp
var filtered = query.Where(x => x.Age > 30);
```
```csharp
var orderedDesc = query.OrderByDescending(x => x.Name);
```
```csharp
var projected = query.Select(x => new { x.Name, x.Age });
```
```csharp
var firstOrDefault = query.FirstOrDefault();
var lastOrDefault = query.LastOrDefault();
var single = query.Single();
```
## 3: So Much Optimization ⚙️
Because the query is structured into a **tree** of expressions, the provider (such as **Entity Framework Core**) can take that expression tree and translate it into a query language appropriate for the data store, such as **SQL** for **SQL Server** or **PostgreSQL**, or **LINQ** for in-memory data stores.
Since the translation is handled by the provider, it can optimize the query for better performance and efficiency. This optimization might involve translating the query into a more efficient SQL statement, applying indexes, or other database-specific optimizations. This allows you to query the data store efficiently without needing to manually optimize each query.
## Extending IQueryable<T>
I was coding a repository for a blog project, and I wanted to add sorting, pagination, and filter by title to the `GetLatestPosts` method. Now while it's possible to cram them in the same method, it'd be much nicer if there's a way to place those methods into a centric place, and just chain call them to compose that perfect query. Enter Extension methods!
> ⚠️ Extension methods are not something specific to IQueryable only, they can be used to extend any type.
Before I show you the extension methods code, I'd like to show you the refactored code, and how the improved version actually looks like:
```csharp
public async Task<PaginatedReadOnlyCollection<Post>>
GetLatestPostsAsync(int pageNumber, int pageSize, string? title, PostSortOption sortOption, CancellationToken cancellationToken)
{
try
{
var query = db.Posts.AsQueryable();
var filteredQuery = query.ApplyFilter(title);
var sortedQuery = filteredQuery.ApplySorting(sortOption);
var totalCount = await filteredQuery.CountAsync(cancellationToken);
var posts = await sortedQuery
.ApplyPagination(pageNumber, pageSize)
.Execute(cancellationToken);
var paginatedPosts = new PaginatedReadOnlyCollection<Post>(
totalCount,
pageNumber,
pageSize,
posts.AsReadOnly()
);
return paginatedPosts;
}
catch (OperationCanceledException)
{
logger.LogInformation("Loading posts was cancelled");
return PaginatedReadOnlyCollection<Post>.Empty(pageNumber, pageSize);
}
}
```
This is a lot of code I know, but the main focus here is the 4 methods that aren't LINQ methods.
`ApplyFilter(string)`, `ApplySorting(PostSortOption)`, `ApplyPagination(int, int)`, and `Execute(CancellationToken)`.
All these methods are extension methods I wrote to extend on `IQueryable<Post>`, which makes it much cleaner and more concise to write and compose large queries on the `Post` data model.
Here's the code inside `PostsQueryExtensions.cs` which hosts those extension methods we just discussed:
```csharp
public static class PostsQueryExtensions
{
public static IQueryable<Post> ApplyFilter(this IQueryable<Post> query, string? title)
{
if (!string.IsNullOrEmpty(title))
{
query = query.Where(post => post.Title.Contains(title, StringComparison.OrdinalIgnoreCase));
}
return query;
}
public static IOrderedQueryable<Post> ApplySorting(this IQueryable<Post> query, PostSortOption sortOption)
{
return sortOption switch
{
PostSortOption.MostComments => query.OrderByDescending(p => p.Comments.Count),
PostSortOption.MostLiked => query.OrderByDescending(p => p.LikeCount),
PostSortOption.MostViews => query.OrderByDescending(p => p.Views),
_ => query.OrderByDescending(p => p.PublishedOn)
};
}
public static IQueryable<Post> ApplyPagination(this IQueryable<Post> query, int pageNumber, int pageSize)
{
return query
.Skip((pageNumber - 1) * pageSize)
.Take(pageSize);
}
public static async Task<List<Post>> Execute(this IQueryable<Post> query, CancellationToken cancellationToken)
=> await query.ToListAsync(cancellationToken);
}
```
As you can see, all these methods extend on the query and return an updated version of it, essentially, composing the entire query before finally the `Execute` method pulls the trigger, and calls `ToListAsync` which in turn, grabs the results of the entire query and enumerates them such that the calling code can read and display the results.
## Conclusion ✅
In this post, we went over the `IQuyerable` interface, from the basics, highlighting key features of it, showing you code samples of how it's used, and lastly we saw how we can extend on this interface for a given data model so that we can facilitate and make writing complex querying code less redundant, more fluent and concise.
I hope that post was a good introductory to this powerful interface, I hope it was useful and you ended up learning something!
If you got any feedback on the code provided in the post, please feel free to point them out!

Certainly! Here's a description for your blog along with a diagram and comments explaining the code:
### Blog Description
Welcome to another exciting tutorial on MicroPython programming! Today, we'll be diving into the basics of controlling an LED using an ESP32 microcontroller. In this tutorial, we'll write a simple MicroPython script to make an LED blink on and off at regular intervals. This is a great starting point for anyone new to MicroPython and microcontrollers, as it covers fundamental concepts like pin configuration and timing functions.
### Code Explanation with Comments
```python
from machine import Pin # Import the Pin class from the machine module
from time import sleep # Import the sleep function from the time module
# Initialize pin 15 as an output pin
led = Pin(15, Pin.OUT)
# Infinite loop to blink the LED
while True:
led.on() # Turn the LED on
sleep(0.5) # Wait for 0.5 seconds
led.off() # Turn the LED off
sleep(0.5) # Wait for 0.5 seconds
```
### Diagram
Here’s a diagram illustrating the connections for this project:
```
ESP32 Microcontroller:
----------------------
___________
| |
| |
| |
| 15 |--------> LED (Anode)
| |
| |
|___________|
|
|
GND
```
**Connections:**
- Connect the longer leg (anode) of the LED to GPIO pin 15 of the ESP32.
- Connect the shorter leg (cathode) of the LED to the GND pin of the ESP32.
### Detailed Code Breakdown
1. **Importing Libraries:**
```python
from machine import Pin
from time import sleep
```
- `from machine import Pin`: This line imports the `Pin` class from the `machine` module, which is used to control the pins of the ESP32.
- `from time import sleep`: This line imports the `sleep` function from the `time` module, allowing us to introduce delays in our code.
2. **Setting Up the LED Pin:**
```python
led = Pin(15, Pin.OUT)
```
- `led = Pin(15, Pin.OUT)`: This line initializes GPIO pin 15 as an output pin. The `Pin` class is used to configure the pin, and `Pin.OUT` specifies that the pin will be used for output.
3. **Main Loop to Blink the LED:**
```python
while True:
led.on() # Turn the LED on
sleep(0.5) # Wait for 0.5 seconds
led.off() # Turn the LED off
sleep(0.5) # Wait for 0.5 seconds
```
- `while True`: This starts an infinite loop that will run forever, continuously executing the code inside the loop.
- `led.on()`: This turns the LED on by setting the voltage of pin 15 to high.
- `sleep(0.5)`: This introduces a delay of 0.5 seconds, keeping the LED on for half a second.
- `led.off()`: This turns the LED off by setting the voltage of pin 15 to low.
- `sleep(0.5)`: This introduces another delay of 0.5 seconds, keeping the LED off for half a second.
By following this tutorial, you'll have a blinking LED that demonstrates the basics of using GPIO pins with the ESP32 and MicroPython. This foundational knowledge will pave the way for more complex projects in the future. Happy coding! | shemanto_sharkar |

1,894,456 | Player Agency: Why so serious? | Again, touching on my previous topics, I’m going to lay out something relatable here…I know, this is... | 0 | 2024-06-20T07:42:30 | https://dev.to/zoltan_fehervari_52b16d1d/player-agency-why-so-serious-mnm | playeragency, videogames, gamedev, gameprogramming | Again, touching on my previous topics, I’m going to lay out something relatable here…I know, this is about gaming, again…
**Stay with me though!**
Player agency is a pivotal(vital, important, etc.) element in many video games, granting players the power to shape their in-game experiences. This feature allows players to make decisions that significantly impact the narrative, environment, and game mechanics, creating immersive and interactive experiences that engage players deeply.
## The spoilers keep piling up, here are the Main Points
Player agency involves giving players control and decision-making power within a game, which enhances engagement and satisfaction. It allows players to influence the story, making their experience more personalized and rewarding. This article explores the positive aspects of player agency, its impact on gaming, and examples of successful implementations.
## Can’t get away from Key Takeaways
1. Definition: Player agency allows players to control their in-game decisions, affecting the narrative and gameplay.
2. Impact on Story: Enhances narrative immersion by enabling players to influence story outcomes.
3. Benefits: Increases player investment, replayability, immersion, creativity, and social engagement.
4. Challenges: Some games offer only superficial choices, leading to a lack of genuine control and engagement.
## Understanding Player Agency in Gaming
Player agency refers to the level of control and decision-making power that players have within a game. It allows players to actively shape their experience, making choices that impact the story and gameplay. Games that emphasize player agency create more immersive and engaging experiences by offering meaningful choices that influence the game’s direction and outcome.
## The Impact of Player Agency on the Story
Player agency transforms the narrative by providing players with meaningful choices that affect the story. This shift from linear storytelling to player-driven narratives allows players to tailor their experience, fostering a sense of ownership and deeper emotional connection to the game. Games that fail to offer genuine player agency risk disengaging players, even with high-quality graphics and sound design.
## The Benefits of Player Agency in Gaming
1. Enhanced Player Investment and Ownership: Players feel a greater sense of ownership over their in-game journey, increasing satisfaction and emotional engagement.
2. Increased Replayability and Discovery: High levels of player agency lead to branching narratives and multiple endings, encouraging players to replay the game to explore different paths and outcomes.

5. Emotional and Narrative Depth: Choices with moral implications and thought-provoking dilemmas add complexity to the gaming experience.
6. Social and Community Engagement: Multiplayer and online games benefit from player agency by fostering community interaction and discussions about different story paths and outcomes.
## When Player Agency Is Only There in Name
Some games claim to offer player agency but provide superficial decisions with little impact on the overall story or gameplay. These games create an illusion of choice rather than genuine control, leading to a hollow experience and limiting replayability. Successful games empower players to influence the story and gameplay in significant ways, creating engaging and replayable experiences.
## The Problems with Low Player Agency
Games with limited player agency can result in linear, less engaging gameplay experiences. When players feel they have no control over their in-game decisions, it can lead to boredom and a lack of investment. While some narrative consistency is necessary, excessive linearity can undermine player engagement and replayability.
## Technical Background of Player Agency: How Is It Done?
Creating player agency involves a combination of game design, programming, and narrative development. Key strategies and technologies include:
1. Branching Narrative Structures: Multiple paths and outcomes are created based on player choices, managed using flowcharts and narrative design software.
2. Scripting and Programming: Code reacts to player choices, triggering different events and story branches.
3. Procedural Generation: Algorithms dynamically generate content like landscapes and quests, allowing vast possibilities without manual creation.
4. Artificial Intelligence (AI): AI helps NPCs react realistically to player actions and manages dynamic storytelling.
5. Database Management: Stores player decisions and their consequences to ensure narrative continuity.
6. Content Management Systems (CMS): Organizes and manages game elements, ensuring coherence and complexity.
## Good vs. Bad Implementations of Player Agency
**Successful Player Agency:**
- Games like Mass Effect and Dragon Age: Offer meaningful choices that significantly alter the story.
- Games like Skyrim and Red Dead Redemption 2: Allow players to control the narrative and create diverse storytelling possibilities.
**Poorly Executed Agency:**
- Games like The Walking Dead: Survival Instinct and Far Cry 4: Offer superficial decisions with little impact, leading to a disappointing experience.
## Player Agency in Gaming: Then and Now

Platforms like [MetaTrader 4 (MT4)](https://bit.ly/4bdoRrX), MetaTrader 5 (MT5), and cTrader are popular among traders for their comprehensive tools and capabilities.
• Investors: Need platforms that provide extensive research, fundamental data, and portfolio management tools. Broker platforms like TD Ameritrade, E*TRADE, and Schwab are favored by investors for their in-depth analysis and long-term investment tools.
5. Market Focus
• Traders: Often focus on highly liquid [markets](https://bit.ly/forex-markets) with significant price movements, such as forex, stocks, and commodities. The high liquidity in forex and CFD markets is particularly attractive to traders looking for quick opportunities.
• Investors: Tend to invest in a broad range of asset classes, including stocks, bonds, mutual funds, ETFs, and real estate. Their diversified portfolios help to spread risk and achieve long-term growth.
Integrating Forex and CFD Trading
1. Traders and Forex/CFD Markets
• Traders: Leverage the volatility and liquidity of forex and [CFD](https://bit.ly/3z4kIJ8) markets to execute multiple trades within short time frames. These markets offer numerous opportunities for day [trading](https://bit.ly/forex-solid-trading), swing trading, and scalping.
• Broker Platforms: Platforms like MT4, MT5, and cTrader provide the necessary tools for technical analysis, fast execution, and automated trading strategies, making them ideal for traders.
2. Investors and Forex/CFD Markets
• Investors: May use forex and CFDs for hedging purposes or to gain exposure to specific markets without owning the underlying assets. However, they generally focus on longer-term investments like stocks and bonds.
• Broker Platforms: Investors might choose platforms that offer a mix of investment options, including forex and CFDs, to diversify their portfolios while focusing on long-term growth.
Risk Management Techniques
1. Traders
• Stop-Loss Orders: Automatically close a trade at a predetermined loss level to limit risk.
• Take-Profit Orders: Secure profits by closing a trade at a predetermined profit level.
• Position Sizing: Adjusting the size of each trade to manage risk effectively.
• Diversification: Trading multiple assets to spread risk.
2. Investors
• Diversification: Investing in a variety of asset classes to reduce risk.
• Long-Term Holding: Holding investments through market cycles to ride out volatility.
• Regular Reviews: Periodically reviewing and rebalancing the portfolio to align with investment goals.
Conclusion
The key differences between traders and investors lie in their time horizons, strategies, risk tolerance, and use of broker platforms. Traders focus on short-term gains through active trading strategies in volatile markets like forex and CFDs, while investors aim for long-term growth through fundamental analysis and diversified portfolios. Understanding these distinctions is crucial for aligning your approach with your financial goals, risk tolerance, and market preferences. Utilizing the appropriate broker platforms and tools can significantly enhance your effectiveness as either a trader or an investor.

1,894,454 | Understanding SOLID Principles and Their Implementation in React | The SOLID principles, introduced by Robert C. Martin, provide a framework for developing software... | 0 | 2024-06-20T07:37:34 | https://dev.to/rahulvijayvergiya/understanding-solid-principles-and-their-implementation-in-react-fm5 | react, webdev, solidprinciples, designpatterns | The SOLID principles, introduced by Robert C. Martin, provide a framework for developing software that is maintainable, extensible, and adaptable as projects evolve. By adopting these practices, developers can write cleaner and more efficient code. These principles guide the creation of software that remains easy to understand and modify as it grows, ensuring that it stays robust and flexible over time.
## What are SOLID Principles?
SOLID is an acronym representing five principles of object-oriented programming and design, aimed at making software designs more understandable, flexible, and maintainable:
- **Single Responsibility Principle (SRP)**
- **Open/Closed Principle (OCP)**
- **Liskov Substitution Principle (LSP)**
- **Interface Segregation Principle (ISP)**
- **Dependency Inversion Principle (DIP)**
- **Implementing SOLID Principles in React**
---
### 1. Single Responsibility Principle (SRP)
**Principle:** A component should have one, and only one, reason to change, meaning it should have only one job or responsibility.
**Implementation in React:** In React, this translates to ensuring each component does one thing well. Avoid creating large, monolithic components that handle multiple responsibilities. Instead, break them down into smaller, reusable components.
**Bad Example**: Large Component with Multiple
```
Responsibilities
const UserProfile = () => {
const [user, setUser] = useState(null);
const [posts, setPosts] = useState([]);
useEffect(() => {
fetchUser().then(data => setUser(data));
fetchPosts().then(data => setPosts(data));
}, []);
return (
<div>
<div>User Info</div>
<div>User Posts</div>
</div>
);
};
```
**Good Example:** Separate Components for Different Responsibilities
```
const UserInfo = ({ user }) => (
<div>User Info</div>
);
const UserPosts = ({ posts }) => (
<div>User Posts</div>
);
const UserProfile = () => {
const [user, setUser] = useState(null);
const [posts, setPosts] = useState([]);
useEffect(() => {
fetchUser().then(data => setUser(data));
fetchPosts().then(data => setPosts(data));
}, []);
return (
<div>
<UserInfo user={user} />
<UserPosts posts={posts} />
</div>
);
};
```
---
### 2. Open/Closed Principle (OCP)
**Principle:** Software entities should be open for extension but closed for modification.
**Implementation in React:** Achieve this by using higher-order components (HOCs) or custom hooks to add functionality without modifying existing code.
**Example:** Custom Hook
```
const useFetchData = (url) => {
const [data, setData] = useState(null);
useEffect(() => {
fetch(url)
.then(response => response.json())
.then(data => setData(data));
}, [url]);
return data;
};
// Usage in Component
const UserProfile = () => {
const user = useFetchData('/api/user');
const posts = useFetchData('/api/posts');
return (
<div>
<UserInfo user={user} />
<UserPosts posts={posts} />
</div>
);
};
```
---
### 3. Liskov Substitution Principle (LSP)
**Principle:** Objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program.
**Implementation in React:** In React, this means components should be easily swappable. This is often naturally followed due to React's composition model, but ensure props and context usage do not break when swapping components.
**Example:**
```
const UserInfo = ({ user }) => {
if (!user) return null;
return <div>{user.name}</div>;
};
const AdminInfo = ({ admin }) => {
if (!admin) return null;
return <div>{admin.name} - Admin</div>;
};
const UserProfile = ({ userType, user }) => {
const Component = userType === 'admin' ? AdminInfo : UserInfo;
return <Component user={user} />;
};
```

### 4. Interface Segregation Principle (ISP)
**Principle:** A client should not be forced to depend on interfaces it does not use.
**Implementation in React:** Design components with minimal and specific props. Avoid passing large prop objects where only a few fields are necessary.
**Bad Example:** Component with Many Props
```
const UserProfile = ({ user, posts, comments, likes, ...otherProps }) => {
// Component logic
};
```
**Good Example:** Component with Specific Props
```
const UserProfile = ({ user }) => {
// Component logic
};
```
---
### 5. Dependency Inversion Principle (DIP)
**Principle:** High-level modules should not depend on low-level modules. Both should depend on abstractions.
**Implementation in React:** Use context and hooks to manage dependencies and inject them where needed, rather than hardcoding them into components.
**Example:** Creating a Context for User Data
```
const UserContext = createContext();
const UserProvider = ({ children }) => {
const [user, setUser] = useState(null);
useEffect(() => {
fetchUser().then(data => setUser(data));
}, []);
return (
<UserContext.Provider value={user}>
{children}
</UserContext.Provider>
);
};
// Using Context in a Component
const UserProfile = () => {
const user = useContext(UserContext);
return (
<div>
<UserInfo user={user} />
<UserPosts userId={user?.id} />
</div>
);
};
// App Component with UserProvider
const App = () => (
<UserProvider>
<UserProfile />
</UserProvider>
);
```
### Conclusion
In conclusion, adhering to the SOLID principles lays a solid foundation for building software that is not only robust and scalable but also easier to maintain and extend. As technology and requirements evolve, SOLID principles serve as timeless guidelines for crafting software that stands the test of time, promoting sustainable development practices in the ever-changing landscape of software engineering.

1,894,449 | MobX vs. Redux: Why MobX Might Be the Better Choice for Your Next Project | State management can be a scary concept, especially for those new to coding. But fear not, because... | 0 | 2024-06-20T07:32:51 | https://dev.to/mananpoojara/mobx-vs-redux-why-mobx-might-be-the-better-choice-for-your-next-project-29k6 | javascript, tutorial, learning, webdev | State management can be a scary concept, especially for those new to coding. But fear not, because MobX is here to make things a whole lot easier! With its straightforward approach and effortless optimal rendering, MobX simplifies state management in ways you never thought possible.
**What is MobX?**
MobX is a state management library that makes state management simple and scalable by using reactive programming. It allows you to create observable state that automatically updates the UI whenever the state changes. MobX is known for its minimal boilerplate and ease of use, which can significantly speed up development time.
**What is Redux?**
Redux is another popular state management library, particularly well-known in the React ecosystem. It uses a unidirectional data flow and requires actions, reducers, and a central store to manage the state. Redux is praised for its predictability and the way it structures state updates, but it can involve a lot of boilerplate code and a steeper learning curve.
**Key Differences Between MobX and Redux**
> 1. Boilerplate Code
One of the most significant differences between MobX and Redux is the amount of boilerplate code required.
> 2. Learning Curve
Redux has a steeper learning curve due to its strict structure and the need to understand concepts like actions, reducers, and middleware. MobX, on the other hand, is more intuitive and easier to learn, especially for developers new to state management.
> 3. Flexibility vs. Predictability
MobX: Offers more flexibility and less boilerplate. It allows you to write code in a way that feels natural without enforcing strict patterns. This can lead to faster development times and less frustration for developers.
> Redux: Provides predictability and a clear structure that can be beneficial for large teams and complex applications. The unidirectional data flow and strict patterns help maintain consistency, but at the cost of increased complexity.
**Redux Example**
In Redux, you need to define actions, reducers, and a store:
**Actions (actions.js):**
```js
export const increment = () => ({
type: 'INCREMENT'
});
```
Reducer (reducer.js):
```javascript
const initialState = { count: 0 };
const counterReducer = (state = initialState, action) => {
switch (action.type) {
case 'INCREMENT':
return { ...state, count: state.count + 1 };
default:
return state;
}
};
export default counterReducer;
```
Store (store.js):
```javascript
import { createStore } from 'redux';
import counterReducer from './reducer';
const store = createStore(counterReducer);
export default store;
```
Component:
```javascript
import React from 'react';
import { useDispatch, useSelector } from 'react-redux';
import { increment } from './actions';
const Counter = () => {
const dispatch = useDispatch();
const count = useSelector(state => state.count);
return (
<div>
<p>Count: {count}</p>
<button onClick={() => dispatch(increment())}>Increment</button>
</div>
);
};
export default Counter;
```
**MobX Example**
In contrast, MobX requires much less boilerplate:
Store (CounterStore.js):
```javascript
import { makeAutoObservable } from "mobx";
class CounterStore {
count = 0;
constructor() {
makeAutoObservable(this);
}
increment() {
this.count += 1;
}
}
const counterStore = new CounterStore();
export default counterStore;
```
Component:
```javascript
import React from "react";
import { observer } from "mobx-react-lite";
import counterStore from "./CounterStore";
const Counter = observer(() => (
<div>
<p>Count: {counterStore.count}</p>
<button onClick={() => counterStore.increment()}>Increment</button>
</div>
));
export default Counter;
```
**Breaking down MobX step-by-step**
Now that we've covered the basics, let's dive deeper into MobX and unpack this powerful state management tool bit by bit. Think of it like a step-by-step guide to mastering the art of keeping your app data in top-notch shape without breaking a sweat. No need for a Ph.D. in computer science here – MobX is all about simplicity and user-friendliness. I promise you'll be a pro at this in no time. So grab your favorite snack, cozy up in your favorite spot, and let's unravel the mysteries of MobX together!🚀🔥
**Making state management fun (yes, it's possible!)**
Alright, guys and gals, let's dive into how we can make state management a blast! Who said handling app data couldn't be exciting? Fear not, because with MobX, we're turning the tables on boring old state management. Let's inject some fun into our coding journey and see how we can flex our skills with a smile. Get ready to groove with MobX and spruce up your app like never before. Trust me, once you start enjoying managing your state, there's no looking back. So buckle up and get set for a wild ride of state management fun! 🎉💻

> Reactivity: The automatic updates of the UI in response to state changes reduce the need for manual updates and prevent bugs.
> Flexibility: MobX allows you to write code in a way that feels more natural, without enforcing strict patterns.
**Conclusion**
While both MobX and Redux have their merits, MobX stands out for its simplicity, ease of use, and flexibility. If you're looking for a state management solution that minimizes boilerplate and accelerates your development process, MobX is a strong candidate. Give MobX a try in your next project, and experience the benefits of reactive state management firsthand. Happy coding!

This article will cover the AssignmentActivityRenderer implemented in the ScheduleJS Viewer and explain its mechanics.
## What are [ScheduleJS](https://schedulejs.com) renderers?
The concept of an `ActivityRenderer` represents a pluggable renderer dedicated to activity drawing. It focuses on rendering any kind of data in a row. In general, renderers hold drawing strategies related to activities. Note that the `ActivityRenderer` class extends the `Renderer` class. This architecture lets the developer fine-tune his drawing strategy at multiple levels while giving access to time and position calculation methods that will help.
## The [ScheduleJS](https://schedulejs.com) ActivityRenderer class
Below is an example of how you can create an activity renderer in ScheduleJS:
```
// Create your own pluggable ActivityRenderer based on the ActivityBarRenderer class
export class MyActivityRenderer extends ActivityBarRenderer<MyActivity, Row> {
// Override the drawActivity method of the ActivityBarRenderer
protected drawActivity(activityRef: ActivityRef<Action>, position: ViewPosition, ctx: CanvasRenderingContext2D, x: number, y: number, w: number, h: number, selected: boolean, hover: boolean, highlighted: boolean, pressed: boolean): ActivityBounds {
// Draw your activity by using the canvas rendering context 'ctx' API
this._drawMyActivity(ctx, activityRef, x, y, w, h, selected, hover, highlighted, pressed);
// The returned ActivityBounds represents how much space the activity takes (useful for interactions)
return new ActivityBounds(activityRef, x, y, w, h);
}
```
Here is the list of the three advanced activity renderer classes you can extend to start creating your own renderer faster:
- ActivityBarRenderer: used in Gantt layouts, it represents a bar on the graphics
- ChartActivityRenderer: handles chart-related drawings with a vertical dimension
- CalendarActivityRenderer: draws behind the rows and optimized for read-only
Once you are done with designing your renderer, you can register it using the Graphics API:
```
// Register MyActivityRenderer for activities of type MyActivity in the context of a GanttLayout
const graphics = this.gantt.getGraphics();
graphics.setActivityRenderer(MyActivity, GanttLayout, new MyActivityRenderer(graphics));
```
## Designing a Zoom-level dynamic ActivityRenderer
Every `ActivityRenderer` triggers the inner [ScheduleJS](https://schedulejs.com) drawing engine to draw activities on the screen, letting the developer focus on the high-level decisions for the application. The strategy is to automatically trigger as few redraws as possible when you are operating on the graphics. You can also request manual redraws for specific use cases like data loading, real-time updates, and indirect relations. Doing so allows the developer to optimize the rendering strategy and offers higher resolution and performance.
This article will focus on the `AssignmentActivityRenderer` of the [ScheduleJS Viewer](https://schedulejs.com/en/schedule-js-viewer-2/).
As you can see below, the `AssignmentActivityRenderer` is a simple renderer that draws numbers on the canvas to indicate the Budgeted Units and Actual Units of a project or a task.
Depending on the Zoom-level, we want to visualize the assignments business units per day, week, and month. To implement this in a simple way, we relied on the powerful [ScheduleJS](url) internal data structures and decided to calculate additional activities for all the available timespan.
The .xer data structure only indicates daily values so we had to create the weekly and monthly values by clumping the corresponding daily values. To handle this, the [ScheduleJS Viewer](https://schedulejs.com/en/schedule-js-viewer-2/) uses a `temporalUnit` field in its `AssignmentActivity` model to indicate which `AssignmentActivity` corresponds to which `ChronoUnit`.
```
export class AssignmentActivity extends MutableActivityBase {
// Attach a temporalUnit to the assignment activity
temporalUnit: ChronoUnit;
value: number;
}
```
Now we have to tell the renderer which resolution is currently used. To do this, the Dateline API comes in handy.
As you can see below, the dateline is composed of two rows:
- The first row of cells gives information on the current timespan (ex: Week 49, Monday 29, November 2021)
- The second row of cells breaks down the top cell in multiple smaller cells (ex: Day 29)
To draw our activities as text, we will use the Canvas `ctx.fillText` method.
Now, to select which activity has to be drawn at any time, we decide to trigger this method conditionally after we confirmed the activity `temporalUnit` is the same temporal unit used by the Dateline 2nd row cells. As the renderer draws every frame, adding this condition to our renderer will only draw either the Monthly, Weekly, or Daily `AssignmentActivities` at a given time.
## A few words on the [ScheduleJS](https://schedulejs.com/) data structure
Graphics in ScheduleJS are made to support millions of activities at any given time. To make sure our graphics keep the best performance possible, ScheduleJS implements a binary tree representation of the data in memory to quickly access any activity node and reduce processing time.
The implementation described above takes advantage of this feature to calculate and store every information required for the graphics before runtime to further increase navigation smoothness.
This example is a simple use case of a dynamic renderer. The Zoom-level is just one of the various public variables that you can find in a ScheduleJS application. The same logic can also be applied to any external variables to draw conditionally and build your own user interface and experience.
