The cloud revolution has... | 0 | 2024-07-11T12:57:15 | https://dev.to/d_sourav155/reduce-your-cloud-bill-cost-optimization-strategies-in-the-sdlc-ghj | ## Introduction
Are Your Cloud Bills Getting Out of Control?
The cloud revolution has transformed how we build and deploy software. Scalability, flexibility and on-demand resources are just a few of the benefits that have made cloud services a cornerstone of modern development. However, running cloud services can be a double-edged sword. Scalability and flexibility are amazing but keeping those costs in check is crucial. Managing cloud costs can be a challenge especially if optimization isn't ingrained throughout the entire Software Development Life Cycle (SDLC).
The good news is that cost optimization doesn't have to be an afterthought. By integrating cost-conscious practices into each stage of the SDLC, you can significantly reduce your cloud service expenses while maintaining optimal performance and reliability.
## The SDLC Stages and Cost Optimization Strategies
### Planning and Requirements Gathering
**Identify Core Functionalities:** Before development, clearly define the essential features and functionalities your service needs. Adding unnecessary features late in the game can lead to bloated services with higher resource demands. Focus on what truly matters for your users and avoid building features that won't be used.
**Choose the Right Tool and Technology:** When evaluating technologies and tools consider their cost implications. Open-source solutions can offer significant savings compared to proprietary options. Cloud-based services often have flexible pricing structures based on usage so explore these options as well. Don't forget to factor in traffic management solutions – both for internal and external traffic distribution. Look for open-source load balancers or consider cost-effective tiers offered by cloud providers.
### Design and Development
**Optimize Code for Efficiency:** Developers should write clean and efficient code that utilizes resources effectively. This can involve techniques like code profiling to identify bottlenecks, leveraging caching mechanisms and avoiding unnecessary data processing.
**Design for Scalability:** Consider how your service will handle fluctuations in user load. Implement autoscaling practices that automatically adjust resource allocation based on demand. This ensures you're not paying for unused resources during low-traffic periods.
### Testing and Deployment
**Leverage Infrastructure as Code:** IaC tools allow you to define infrastructure configurations as code, enabling automated provisioning and deployment. This reduces manual configuration errors and ensures consistent environments leading to more efficient resource utilization.
**Performance Testing:** Performance testing helps identify bottlenecks and areas for optimization before deploying your service to production. This can prevent costly issues like slow response times or crashes that require additional resources to fix.
### Operations and Monitoring
**Rightsizing Resources:** Continuously monitor your service's resource consumption (CPU, memory, storage) and identify opportunities to downsize instances or adjust configurations. Cloud providers often offer various instance types with different capabilities and costs. Choose the ones that best fit your service's needs and avoid overprovisioning.
**Traffic Management Monitoring:** Just like any other component your traffic management solutions need monitoring. Track the health and performance of both internal and external load balancers. Identify potential bottlenecks and optimize configurations for efficient traffic distribution ensuring smooth user experiences.
**Cost Monitoring and Analysis:** Utilize cloud billing tools and cost management platforms to gain insights into your service's spending patterns. Identify areas for cost optimization such as underutilized resources or unused services.
**Continuous Feedback Loop**
Cost optimization isn't a one-time effort. It's an ongoing process. Share the insights you gain from monitoring and cost analysis with your development and operations teams. This collaborative approach allows for continuous improvement. Developers can focus on code efficiency, operations can refine traffic management strategies and everyone can work together to achieve the most cost-effective solutions.
## Benefits of Implementing These Strategies
By integrating these cost optimization strategies throughout the SDLC, you can gain significant rewards:
Reduced Cloud Service Costs: This is the most obvious benefit but it's also the most impactful. By eliminating waste and optimizing resource utilization you can significantly lower your cloud service expenses freeing up resources for other business priorities.
Improved Performance and Reliability: Cost optimization often leads to a leaner and more efficient service. By rightsizing resources and optimizing traffic management you ensure your service can handle peak loads without compromising performance or user experience.
Informed Decision-Making for the Future: The insights gained from cost monitoring and analysis empower
Informed Decision-Making for the Future: The insights gained from cost monitoring and analysis empower you to make informed decisions for future cloud service development. You'll have a clearer understanding of your resource usage patterns and can choose the most cost-effective tools and technologies for new projects.
## Conclusion
The cloud offers a powerful platform for building and deploying innovative solutions. By integrating cost optimization practices into the very fabric of your SDLC you can ensure you're getting the most out of your cloud investment. Remember, cost optimization is a continuous journey not a destination. By fostering a culture of cost-consciousness throughout your organization you can effectively tame the cloud beast and achieve optimal performance, reliability and affordability for your cloud services.

1,919,747 | An easy intro to edge computing | Wondering what edge computing is all about? If you've ever visited a website before you can... | 0 | 2024-07-12T11:54:59 | https://dev.to/fastly/an-easy-intro-to-edge-computing-3ced | webdev, learning, serverless, cloud | Wondering what edge computing is all about? If you've ever visited a website before you can understand it! It's also easier than you might expect to get started using it. In this series we'll introduce the concepts and practices in leveraging the edge to enhance your websites using Glitch and Fastly.
***But first, let's explore how we got here...***
## Web hosting
When I visit a website, my browser downloads the site content onto my device, like text, images, other media assets, and code defining how the browser should render the pages I interact with on my device.
The content of the site often comes from servers that are far away from me. For example, I'm in the UK, and many of the sites I visit are hosted in the US. It's a long way for the content to travel, which can cause _latency_ – it can make the experience slow. 🐢
## Caching
Let's say there's a website I visit every day – it would be pretty wasteful to download everything fresh each time, especially since the site has image files like logos that don't change very often. Luckily my browser has the ability to cache these assets – to store copies of them locally on my device.
The website owner can specify caching rules that tell the browser how long to keep these assets before requesting them fresh from the server.
> 🤔 Browser caching saves a ton of traffic and makes the web faster for us, but what if my neighbor down the street often also visits the same website? Are we both downloading the same content all the way across the planet..!?
## CDNs
CDNs (Content Delivery Networks) add a layer of caching to the web by storing copies of assets on their servers. CDN servers are positioned at locations all around the globe. 🌍
If the website me and my neighbor visit every day is using a CDN, we can both get the assets from a server located closer to us than the server hosting the website. This means I can request the site and get at least part of the response from a CDN server in the UK, instead of my request having to go all the way to the US!
This is what happens when I make a request to a website using a CDN:
* If the content is stored in the CDN cache, I'll get a response from there and my request will not need to go anywhere near the _origin_ – where the site is hosted.
* If the content isn't in the cache, the CDN will make the request to the origin and return the content to me.
* If the content is cacheable, the CDN will store it so that people visiting the site after me receive the response directly from the CDN.
> If the website owner decides to update the content, for example the site design, and they don't want users getting the version that's stored in cache anymore, they can _purge_ the cache, so that new requests fetch the updated content from the origin host. Once the new content is stored in the CDN cache, subsequent visitors receive it from the CDN server near them and once again enjoy a faster experience.
## The edge
Caching improves website performance through networks of servers that are located nearer users – _edge_ networks. But these servers can do more than return assets – they can execute code. This means we can build processing into our websites that runs near the end user – that's edge computing!
Edge computing lets us build applications that center the user, running code that enhances website UX close to relevant user information. Many IoT (Internet of Things) applications also leverage the edge to run processing nearer user devices.
Edge applications sit between the user and origin, and [can do many things](https://www.fastly.com/documentation/solutions/use-cases/):
* 🚧 Manipulate the request from the user and/or the response from the origin, for example to include geolocation data or personalize the display.
* 🧪 Deliver different versions of the site to user cohorts, for example to run A/B testing.
* 🏭 Respond to the user with content generated entirely at the edge without even using an origin server.
* ⛑️ Handle origin errors to provide a reliable experience even if something goes wrong at the website host.
* 🔐 Carry out parts of website functionality at the edge, like authentication.
* 💌 Power instant realtime communication with users around the globe.
## Building the future of the web
Most large websites now use cloud hosting – where the site runs on servers managed by a provider who allocates resources on demand. These web applications are often _serverless_, where the cloud provider also manages provision of the server infrastructure – the platform the website runs on. These serverless cloud technologies expose server resources through software interfaces – _so we can control what happens at the server using code_.
The _programmable edge_ brings this pattern to edge networks – developers can control everything that happens between the user and the hosting server in code. This enables developers to build powerful applications that create new kinds of user experience.
🎏🚀 **Technologies like edge computing have so far mainly been used by large organizations. We're working to make it easier for everyone to access these capabilities, to enable you to build the future of the web using Fastly and Glitch. Stay tuned for step by step tutorials walking you through doing just that!**

1,919,748 | Simple SVG Animations | Sections - Seeing Stars - Oh YEAH Baby!!! I'm a big fan of the SVG... | 0 | 2024-07-12T14:14:25 | https://dev.to/valcas/simple-svg-animations-58fb | svg, javascript, react, animation | ## Sections
## - [Seeing Stars](#stars)
## - [Oh YEAH Baby!!!](#ohyeah)
I'm a big fan of the SVG image format in web applications. They allow developers to resize images without the loss of quality you'll get when doing the same with raster images. Not only that, but the XML that makes up an SVG image can be added to the DOM allowing elements of the SVG can be addressed in the same way as other HTML elements within the DOM. Once the SVG has been added to the DOM in this way, it's possible to manipulate it via Javascript and CSS, creating interesting animations.
## <a id="stars">Seeing Stars</a>
Take this SVG image as an example. The image was created using [Inkscape](https://inkscape.org/) with two separate layers. The first layer contains the text "PRESENTING" which is arched using the [text on path](https://www.youtube.com/watch?v=WZSy2ejgCRk) method of curving texts. Select the result tab below to preview the animated image...
{% embed https://jsfiddle.net/valcas/uyp9owgt/140/ %}
Next I added a new layer to the image, gave it the name "stars" and placed varying sizes of the star image randomly on the layer. This can be seen in the screenshot below where I changed the star colour to black so that they're easier to see.
Once the SVG image has been saved, it's now ready to embed in a webpage but just using an <image> tag won't allow you use it in the way you want. Instead we need to wait until the page renders and then fetch the image via a simple rest call. In this example I use the [Axios library](https://axios-http.com/) to make that call.
```
// The PresentingAnimator class is explained later
const presentingAnimator = new PresentingAnimator();
const initialized = useRef(false);
useEffect(() => {
if (!initialized.current) {
fetchPresentingSVG();
initialized.current = true;
presentingAnimator.animate();
}
}, []);
async function fetchPresentingSVG() {
const resp = await axios.get("./dotspot/svg/presenting.svg");
var anchor = document.getElementById("svgpresentinganchor");
var svgEle = document.createElement("div");
svgEle.style.margin = "0 auto";
svgEle.style.maxWidth = "350px";
svgEle.innerHTML = resp.data;
anchor?.appendChild(svgEle);
}
...
<div>
<div id="svgpresentinganchor"
style={{
width: "100%", padding: "50px", marginLeft: "30px", borderRadius: "20px",
background: "#666", float: "right", width: "400px"
}}
></div>
</div>
```
Now that the SVG has been created, fetched and loaded into the webpage we can start to animate it. The PresentingAnimator class takes care of this task...
```
export default class PresentingAnimator {
running: boolean = false;
timer: any;
parent: any;
stars: Array<any> = [];
starCount = 0;
currentStars: any = []
// 1. Entry Point
animate() {
var _this = this;
// 2. Find the graphics element that has the inkscape:label attribute value of "stars"
var elements = document.querySelectorAll("svg > g");
elements.forEach(g => {
if (g.getAttribute("inkscape:label") == "stars") {
_this.parent = g;
}
});
this.init();
this.start();
}
init() {
// 3. Find all children in the "stars" parent element and make them invisible
this.stars = this.parent.querySelectorAll("g");
this.starCount = this.stars.length;
this.stars.forEach(g => {
g.style.opacity = 0;
});
}
start() {
// 4. Start to make a random star visible every 200 milliseconds
// and record it in the currentStars array
this.timer = setInterval(() => {
var index = Math.floor(Math.random() * this.starCount);
if (this.currentStars.indexOf(index) == -1) {
var starAnimator = new StarAnimator()
starAnimator.start(this.stars[index], index, this)
this.currentStars.push(index);
}
}, 200);
}
// 5. Called when the target star has been faded out fully
complete(index: any) {
var i = this.currentStars.indexOf(index);
this.currentStars.splice(i, 1);
}
}
class StarAnimator {
star: any
timer: any;
opacity = 0;
fadeout = false;
index = -1;
parent: any
start(star: any, index: any, parent: any) {
this.star = star;
this.index = index;
this.parent = parent;
this.timer = setInterval(() => {
if (this.fadeout) {
this.opacity -= 0.01;
if (this.opacity < 0) {
clearInterval(this.timer);
this.parent.complete(this.index)
}
} else {
this.opacity += 0.01;
}
if (this.opacity > 1) {
this.fadeout = true;
}
this.star.style.opacity = this.opacity
}, 10);
}
}
```
1. The entry point called from the page Javascript when the DOM has mounted
2. This gets called from the page Javascript when the DOM has mounted
3. The "init" function is called before any animation begins. It finds all child elements in the parent "stars" element and makes them invisible using the opacity attribute.
4. The "start" function is called when we want to start animating the stars. We start a new timer every 200 milliseconds, get a random star index in the child elements, check to see if it's in the currentStars array and then animate it. A new StarAnimator class is created with then index and it takes care of fading in to full visibility and then fading out to invisibility once more.
5. The "complete" function is called from the StarAnimator instance and the target star is removed from the currentStars array.
## <a id="ohyeah">Oh YEAH Baby!!!</a>
This is another simple, text based SVG image that has been given a 1960's, Austin Powers style makeover and doesn't require a great deal of graphic design skills. As before, select the result tab below to preview the animated image...
{% embed https://jsfiddle.net/valcas/1fwbmpnx/29/ %}
Once again, I created this image in Inkscape using a size 48pt Bauhaus 93 font which I then converted to path elements, applied a long shadow and rotated slightly. It's embedded into the webpage in the same way as the "Presenting" image above using an Axios rest call.
```
export default class OhYeahAnimator {
running: boolean = false;
timer: any;
// 1. Variables
colourParams = {
r: { value: 152, descending: false },
g: { value: 0, descending: false },
b: { value: 200, descending: false },
};
isRunning() {
return this.running;
}
// 2. the entry point
animate() {
this.running = true
this.timer = setInterval(() => {
this.changeElements();
}, 30);
}
stop() {
clearInterval(this.timer);
}
// 3. Change the colour
changeElements() {
this.getNextRGB(this.colourParams.r, 1);
this.getNextRGB(this.colourParams.g, 2);
this.getNextRGB(this.colourParams.b, 3);
var rgb =
"rgb(" +
this.colourParams.r.value +
"," +
this.colourParams.g.value +
"," +
this.colourParams.b.value +
")";
this.changeElementList(
document.querySelectorAll("svglogoanchor > svg > g > g > path"),
rgb
);
this.changeElementList(
document.querySelectorAll("svg > g > g > g > path"),
rgb
);
}
// 4. Change colours for all elements at a specific level
changeElementList(elements: any, rgb: any) {
for (var ele in elements) {
if (elements[ele] != null && elements[ele].style != null) {
elements[ele].style.fill = rgb;
}
}
}
// 5. Determine the next colour
getNextRGB(param: any, inc: any) {
var ret = param.value;
if (param.descending) {
ret -= inc;
} else {
ret += inc;
}
if (ret < 0) {
ret = 0;
param.descending = false;
} else if (ret > 255) {
ret = 255;
param.descending = true;
}
param.value = ret;
}
}
```
1. The colour variables that store the current values as they change
2. The entry point called from the page Javascript when the DOM has mounted. It calls the changeElements function every 30 milliseconds.
3. This function calls the getNextRGB function for each of the r,g & b variables with a different increment value for each. All of the child graphic elements are then set to that colour
4. The changeElementList accepts a list of graphic elements to be changed. Having it in a function allows different levels of elements to be handled separately.
5. The getNextRGB checks to see if the passed rgb element is currently incrementing or decrementing. When the value reaches 255 or 0 respectively, the descending flag is reset
And there you have it. Like I said at the start, I like the flexibility afforded by SVG images. They can really add a bit of pizzazz that you might not otherwise get using animated gifs. They can also add interactivity by hooking up to mouse events, etc. I didn't cover that here so I'll come back to that again.
Thanks for reading!

We will discuss Python and my experience as a FlatIron student learning it for the 2nd time. I had a Python class a few years ago in a community college class and it was exciting. Python Is my favorite coding language so far. The options are endless and exciting, all the way from coding machines to just a small birthday tracker linked to SQL. My project was making a birthday tracker, We all know your mom/dad/partner has gotten upset if you forget their birthday. Learning Python was challenging due to Classes and iteration being a lot different from JavaScript, Except once I learned ipdb or breakpoint or using print to see what's happening it helped so much. Learning JavaScript first taught me that console.log/print shows you what that data is and helps code through it. Seeing what you are working on makes coding 100x easier. Python will be the language I use to make more projects after school. My next project is going to be a Discord bot! I want to make something that you use ! or . followed by something that will run my code and return what I want. I want the bot to return random quotes that have been said before from our friend group. When something funny happens we quote it in the channel and once a year we go back and re-read that and reminisce about that moment we all shared. An easy .randomquote in a discord chat channel that returns a random quote wouldn't be too hard but very fun and exciting. Python makes me want to be creative and nothing against JavaScript/react I feel those have a lot of use for websites/CSS and more except Python has more value to me at the moment for the projects I have planned In the future. | killerfox007 |
1,919,753 | Email Deliverability Audit: Ensuring Your Emails Reach the Inbox | What is Email Deliverability? Email deliverability refers to the ability of your emails to... | 0 | 2024-07-11T13:04:34 | https://dev.to/accuwebhosting/email-deliverability-audit-ensuring-your-emails-reach-the-inbox-43 | email, audit, marketing, inbox | ## What is Email Deliverability?
Email deliverability refers to the ability of your emails to successfully reach your subscribers' inboxes without being filtered into spam or rejected by email servers. High deliverability ensures that your email marketing campaigns are effective, as your messages are seen and engaged with by your audience.
### Importance of an Email Deliverability Audit
Conducting an email deliverability audit is crucial for identifying and resolving issues that might be hindering your emails from reaching the inbox. This audit helps in improving your sender reputation, ensuring compliance with email regulations, and enhancing overall engagement rates. By regularly auditing your email deliverability, you can maintain a healthy email marketing strategy and achieve better results from your campaigns.
## Understanding Email Deliverability
### Key Metrics: Delivery Rate, Inbox Placement Rate, and Bounce Rate
**1. Delivery Rate:** The percentage of emails that were successfully delivered to the recipients' email servers.
**2. Inbox Placement Rate:** The percentage of emails that successfully land in the inbox, as opposed to the spam folder.
**3. Bounce Rate:** The percentage of emails that were not delivered. Bounces can be categorized into hard bounces (permanent delivery failures) and soft bounces (temporary issues).
Factors Affecting Email Deliverability
Several factors influence email deliverability, including the quality of your email list, the reputation of your sending IP address, the content of your emails, and the authentication protocols you use. Understanding these factors helps in identifying the areas that need improvement during the audit.
## Pre-Audit Preparation
### Gathering Necessary Data and Tools
Before starting the audit, gather all relevant data and tools. This includes access to your email service provider (ESP) reports, email list data, sender reputation tools, and authentication records. Having this data at hand will facilitate a comprehensive audit.
### Setting Clear Objectives for the Audit
Define clear objectives for your email deliverability audit. Objectives might include identifying and removing invalid email addresses, improving sender reputation, ensuring compliance with email authentication protocols, and increasing inbox placement rates.
## Email List Health Check
### Importance of a Clean Email List
A clean email list is the foundation of good email deliverability. Regularly cleaning your list ensures that you are only sending emails to valid and engaged subscribers, reducing the chances of bounces and spam complaints.
### Using Bulk Email Verification Tools
Bulk email verification tools, such as those recommended in AccuWeb Hosting’s blog, are essential for identifying and removing invalid or risky email addresses from your list. These [bulk email verification](https://www.accuwebhosting.com/blog/top-10-bulk-email-list-verification-validation-services-compared/) tools check the validity of email addresses, detect disposable and role-based emails, and provide a deliverability score.
### Removing Hard and Soft Bounces
Hard bounces occur when an email cannot be delivered due to a permanent issue, such as an invalid email address. Soft bounces are temporary issues like a full inbox or server problems. Regularly removing hard bounces from your list and monitoring soft bounces to address any recurring issues is crucial for maintaining a healthy email list.
## Sender Reputation Analysis
### Understanding Sender Score
Sender score is a measure of your email sending reputation. It is calculated based on factors like email volume, complaint rates, and bounce rates. A high sender score indicates a good reputation, while a low score can result in your emails being blocked or sent to spam.
### Tools to Check Sender Reputation
Several tools can help you check and monitor your sender reputation, such as SenderScore.org and Google's Postmaster Tools. These tools provide insights into your sender score, feedback loops, and other reputation metrics.
### Strategies to Improve Sender Reputation
To improve your sender reputation, focus on sending relevant and engaging content, maintaining a clean email list, and adhering to email best practices. Avoid sending emails to unengaged subscribers, as this can lead to high complaint rates. Consistently monitor your sender score and address any issues promptly.
## Email Authentication
### Importance of SPF, DKIM, and DMARC
Email authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) are critical for verifying the authenticity of your emails. These protocols help protect against email spoofing and phishing attacks, enhancing your email deliverability.
### How to Implement Email Authentication Protocols
**1. SPF:** Publish an SPF record in your DNS settings to specify which IP addresses are authorized to send emails on behalf of your domain.
**2. DKIM:** Enable DKIM signing on your email server to add a digital signature to your emails, verifying their authenticity.
**3. DMARC:** Set up a DMARC policy to instruct email receivers on how to handle emails that fail SPF or DKIM checks. Monitor DMARC reports to identify and address any issues.
### Tools for Verifying Email Authentication
Use tools like MXToolbox and DMARC Analyzer to verify your email authentication setup. These tools can check your SPF, DKIM, and DMARC records and provide insights into any configuration issues that need to be resolved.
## Content and Design Review
### Ensuring Content Relevance and Quality
The content of your emails plays a significant role in deliverability. Ensure your emails are relevant, engaging, and provide value to your subscribers. Avoid using spammy language, excessive capitalization, and too many exclamation marks, as these can trigger spam filters.
### Avoiding Spam Triggers in Content
Spam filters use various criteria to identify spammy emails. To avoid being flagged, steer clear of common spam triggers like misleading subject lines, too many images or links, and attachments. Use a spam checker tool before sending your emails to identify and fix any potential issues.
### Mobile Optimization and Responsive Design
With a significant portion of emails being opened on mobile devices, it’s crucial to optimize your emails for mobile. Use responsive design techniques to ensure your emails look good on all devices, with easy-to-read text, properly sized images, and clear CTAs.
## Technical Infrastructure
### Reviewing Email Service Provider (ESP) Settings
Ensure your ESP settings are correctly configured to support high deliverability. This includes setting up authentication protocols, managing bounce handling, and using dedicated IP addresses if possible. Review your ESP’s deliverability best practices and guidelines.
### Importance of a Dedicated IP Address
Using a dedicated IP address for your email sending allows you to control your sending reputation. Shared IP addresses can affect your deliverability if other users on the same IP have poor sending practices. Monitor your dedicated IP reputation and maintain consistent sending patterns.
### Monitoring Email Sending Domain
Keep a close watch on your sending domain’s health. Regularly check domain reputation using tools like Google Postmaster Tools and ensure your domain is not blacklisted. Address any issues promptly to maintain a good domain reputation.
## Engagement Metrics
### Tracking Open Rates, Click-Through Rates, and Engagement
Monitor key engagement metrics like open rates, click-through rates, and overall engagement levels. These metrics provide insights into how well your emails are performing and can highlight areas for improvement. High engagement rates indicate that your emails are relevant and valuable to your subscribers.
### Strategies to Improve Subscriber Engagement
To boost engagement, focus on delivering personalized and relevant content. Segment your email list based on subscriber preferences and behaviors, and tailor your messages accordingly. Use compelling subject lines, clear CTAs, and engaging visuals to capture your audience’s attention.
### Handling Inactive Subscribers
Regularly identify and address inactive subscribers. Send re-engagement campaigns to win back their interest or ask them to update their preferences. If subscribers remain unengaged, consider removing them from your list to maintain a healthy engagement rate and improve overall deliverability.
## Compliance with Email Regulations
### Understanding CAN-SPAM, GDPR, and Other Regulations
Email marketing is governed by various regulations like the CAN-SPAM Act, GDPR, and others, depending on your target audience’s location. These regulations set rules for obtaining consent, providing opt-out options, and protecting subscriber data.
### Ensuring Compliance in Your Email Campaigns
To ensure compliance, obtain explicit consent from subscribers before sending them emails. Provide clear and easy-to-find unsubscribe links in every email and honor opt-out requests promptly. Regularly review and update your privacy policies to align with current regulations.
## Monitoring and Reporting
### Setting Up Regular Monitoring Processes
Establish regular monitoring processes to keep track of your email deliverability metrics. Use dashboards and automated reports to stay informed about key performance indicators and identify any issues early on.
### Key Metrics to Track Post-Audit
Post-audit, continue to track important metrics like delivery rate, inbox placement rate, bounce rate, open rate, and click-through rate. Regularly review these metrics to gauge the effectiveness of your improvements and make necessary adjustments.
### Using Reports to Continuously Improve Deliverability
Leverage the insights from your monitoring reports to continuously refine your email marketing strategy. Identify trends, address recurring issues, and implement best practices to maintain high deliverability rates over time.
## Action Plan for Improvements
### Prioritizing Issues Identified in the Audit
After completing the audit, prioritize the issues based on their impact on deliverability. Focus on the most critical areas first, such as fixing authentication issues, cleaning your email list, and improving sender reputation.
### Creating a Step-by-Step Improvement Plan
Develop a step-by-step improvement plan to address the identified issues. Assign responsibilities, set timelines, and track progress to ensure that each area is addressed systematically.
### Tracking Progress and Making Adjustments
Regularly review the progress of your improvement plan and make adjustments as needed. Stay flexible and adapt your strategy based on the results and insights gained from ongoing monitoring and reporting.
## Conclusion
Conducting an email deliverability audit is essential for ensuring your emails reach your subscribers' inboxes and achieve the desired engagement. By understanding the factors affecting deliverability, maintaining a clean email list, implementing proper authentication protocols, and continuously monitoring your metrics, you can enhance your email marketing strategy. Regular audits and adherence to best practices will help you maintain high deliverability rates, protect your sender reputation, and drive better results from your email campaigns.

1,919,754 | Salting & Hashing🍳 | What is salting 🧂? Salting is the process of adding data into a value before hashing. ... | 0 | 2024-07-11T13:07:32 | https://dev.to/notedbyneosahadeo/salting-hashing-21ge | cybersecurity, beginners | ## What is salting 🧂?
Salting is the process of adding data into a value before **hashing**.
## What is hashing #️⃣?
Hashing is the process of converting data into a *fixed-length* string.
>fixed-length: all hashes will have the same length
⚠️Something important to highlight is that **hashing is not encrypting**; Hashing or encryption depends on what the ultimate goal of that obfuscation is (orginisation regulations are a factor).
### Here's an example:
> User 1
>```bash
>(~🐧): echo password | sha256sum
>6b3a55e0261b0304143f805a24924d0c1c44524821305f31d9277843b8a10f4e>
>```
> User 2
>```bash
>(~🐧): echo password | sha256sum
>6b3a55e0261b0304143f805a24924d0c1c44524821305f31d9277843b8a10f4e>
>```
The **hashed** passwords are identical; and that makes sense, they're the same password passed through the same algorithm. The problem arises when two separate users have the same **hashed** password and a bad actor gets a hold of these password and they can draw similarities.
#### Hypothetical scenario of compromised data:
**User 1** uses the same password for every-site (not an uncommon thing). One of the sites gets their user-data leaked (also not an uncommon thing) which happens to have **User 1**'s raw password stored. Then another site gets leaked that has **User 1** and **User 2**'s passwords that are hashed (but not salted). It's as easy as running a `grep` search and comparing hashes.
---
### Adding a random SALT:
> User 1
> ```
>(~🐧): echo 01anv3password | sha256sum
>afe1f6368ce0f7400ee266d52908e190e64779f2f91f4824ea8f1e595fe76ae1
>```
> User 2
> ```
>(~🐧): echo aKdu4ppassword | sha256sum
>a0c787128946d0319fbbbd41312a37c274d7dee345bfad74fca4c670c1bcfea5
>```
From above, adding a random six character SALT changes the **hash** completely.
## Conclusion
- Salting is the process of adding data into a value before hashing it
- Salts should be random
- Hashing is converting data into a *fixed-length* string
- Hashing is not the same thing as encryption

1,919,772 | The Essentials of Reliability Engineering for Modern-Day Developers | As software continues to eat the world, reliability has transformed from being an optional attribute... | 0 | 2024-07-11T13:15:16 | https://mattlantz.ca/articles/the-essentials-of-reliability-engineering-for-modern-day-developers | As software continues to eat the world, reliability has transformed from being an optional attribute to a fundamental expectation for any application. Reliability Engineering is no longer a niche discipline but a cornerstone of developing resilient and dependable systems. Modern day developers especially those at smaller organizations are expected to not only churn out features but also ensure that those features work reliably under varied and often unpredictable conditions. As such, I like to highlight what I consider the essentials of Reliability Engineering, its principles, practices, and how it fits into the modern developer's toolkit.
##### Understanding Reliability Engineering:
Reliability Engineering is a field dedicated to ensuring a system performs its intended function consistently over time. It's about building systems that can gracefully handle load, recover from failures, and provide seamless service to users. Reliability Engineering draws inspiration from traditional engineering disciplines that have long emphasized robustness and fault tolerance.
##### Core Principles:
**Anticipate and Mitigate Failures:**
Rather than only reacting to incidents, a proactive approach involves anticipating potential points of failure and implementing strategies to prevent them. This includes thorough testing, failover mechanisms, and redundancy.
**Automate Responses to Incidents:**
When a system encounters an issue, an automated response can often resolve it faster than human intervention. Employing automation in incident management helps in maintaining system reliability with minimal downtime.
**Continuously Monitor and Improve:**
Key to maintaining reliability is the ongoing monitoring of system performance. Gathering metrics and logs provides visibility into the health of the system, allowing for informed decisions to enhance reliability.
**Embrace a Blameless Culture:**
A blameless post-mortem culture helps teams learn from failures without finger-pointing. This encourages open communication and continuous improvement in system reliability.
##### Reliability Engineering Practices for Developers:
**Design for Failure:**
Developers should assume that all components of a system could fail and design accordingly. This includes implementing retries, timeouts, circuit breakers, and other patterns that help systems cope with failures.
**Implement Chaos Engineering:**
Chaos Engineering is the practice of deliberately introducing disturbances into a system to test its resilience. By doing so, developers can identify weaknesses before they become major issues.
**Build Observability In:**
Observability isn't just about monitoring; it's about understanding deep internals of a system—what's happening and why. Incorporating meaningful logging, metrics collection, and distributed tracing helps in identifying and diagnosing reliability issues early.
**Create SLOs and SLIs:**
Service Level Objectives (SLOs) and Service Level Indicators (SLIs) serve as key performance benchmarks for reliability. Developers should use these to quantify reliability and make informed decisions about where to allocate resources for improvement.
**Emphasize On-call Responsibilities:**
Developers on call are the front line of ensuring a system's reliability. Proper on-call rotations, alerting mechanisms, and support systems are critical to manage the human aspect of reliability engineering.
Reliability is a shared responsibility across the entire development lifecycle. Developers must embrace the principles and practices of Reliability Engineering to build systems that can withstand the complexities of real-world operations. By anticipating failure, automating incident response, monitoring proactively, fostering a blameless culture, and integrating reliability practices into the development process, developers can ensure their creations stand the test of time and usage. Ultimately, the goal is to create software that not only meets users' needs but does so reliably, promoting trust and satisfaction. | mattylantz | |

1,919,780 | Unlocking JavaScript: Innovative Features for Modern Developers | Introduction JavaScript continues to evolve, bringing new features that enhance its capabilities and... | 0 | 2024-07-11T13:27:03 | https://dev.to/rn_dev_lalit/unlocking-javascript-innovative-features-for-modern-developers-1h6e | javascript, frontend, reactnative, react | Introduction
JavaScript continues to evolve, bringing new features that enhance its capabilities and streamline the development process. In 2024, several exciting additions promise to improve code readability, efficiency, and functionality. Let's explore the latest features of JavaScript that every developer should know about.
- Temporal
The Temporal API replaces the existing Date object, offering a more reliable and consistent way to handle dates and times. Temporal simplifies date-related operations, improves code readability, and reduces errors associated with date handling.
Example:
```
const now = Temporal.now.instant();
console.log(now.toString());
```
- Pipe Operator
The Pipe Operator (|>) allows developers to chain functions together, passing the output of one function as the input to the next. This operator promotes a functional programming style, resulting in cleaner and more readable code.
Example:
```
const result = 'hello'
|> text => text.toUpperCase()
|> text => `${text}!`;
console.log(result); // "HELLO!"
```
- Records and Tuples
Records and Tuples introduce immutable data structures to JavaScript. Records are similar to objects, while Tuples are similar to arrays, but both are deeply immutable, ensuring data integrity and preventing unintended changes.
Example:
```
const record = #{ name: "Alice", age: 30 };
const tuple = #["Alice", 30];
console.log(record.name); // "Alice"
console.log(tuple[0]); // "Alice"
```
- RegExp /v Flag
The RegExp /v flag enhances regular expressions by improving case insensitivity and providing better Unicode support. This flag allows for more powerful and precise pattern-matching operations.
Example:
```
const regex = /[\p{Script_Extensions=Latin}&&\p{Letter}--[A-z]]/gv;
const text = "Latin forms of letter A include: Ɑɑ ᴀ Ɐɐ ɒ Ａ, a, A";
console.log(text.match(regex)); // ["Ɑ","ɑ","ᴀ","Ɐ","ɐ","ɒ","Ａ"]
```
- Promise.withResolvers
Promise.withResolvers() is a new static method that simplifies the creation and management of promises. It returns an object containing a promise, a resolve function, and a reject function.
Example:
```
const { promise, resolve, reject } = Promise.withResolvers();
promise.then(value => console.log(value));
resolve('Success!'); // Logs: Success!
```
Decorators allow developers to extend JavaScript classes natively by adding extra functionality to methods and classes without altering their core structure. This feature enhances code reusability and promotes a more modular programming approach.
Example:
```
function log(target, key, descriptor) {
const originalMethod = descriptor.value;
descriptor.value = function(...args) {
console.log(`Calling ${key} with`, args);
return originalMethod.apply(this, args);
};
return descriptor;
}
class Example {
@log
sayHello(name) {
return `Hello, ${name}!`;
}
}
const example = new Example();
example.sayHello('Alice'); // Logs: Calling sayHello with ["Alice"]
```
Conclusion
JavaScript's new features in 2024 promise to revolutionize the way developers write and maintain code.

It is a more advanced and efficient version of ListView, designed to handle large amounts of data with minimal memory consumption. This article will walk you through the basics of RecyclerView, how to set it up in your Android project, and some advanced techniques to take full advantage of its capabilities.
## Why Use RecyclerView?
**Performance:** RecyclerView is more efficient than ListView because it reuses item views, reducing the number of view creations and memory consumption.
**Flexibility:** It supports different types of layouts and complex list items.
**Extensibility:** It allows for the addition of custom animations and decorations.
## Setting Up RecyclerView
**Step 1: Add RecyclerView to Your Layout**
First, add the RecyclerView widget to your layout XML file.
```
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
```
**Step 2: Create the Item Layout**
Define the layout for individual list items. For example, create a file named item_layout.xml in the res/layout directory.
```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="16dp">
<TextView
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="16sp"/>
</LinearLayout>
```
**Step 3: Create the Adapter**
Create a custom adapter by extending RecyclerView.Adapter. This adapter will bind your data to the item views.
```
public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.ViewHolder> {
private List<String> mData;
private LayoutInflater mInflater;
// Data is passed into the constructor
public MyRecyclerViewAdapter(Context context, List<String> data) {
this.mInflater = LayoutInflater.from(context);
this.mData = data;
}
// Inflates the row layout from XML when needed
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = mInflater.inflate(R.layout.item_layout, parent, false);
return new ViewHolder(view);
}
// Binds the data to the TextView in each row
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
String item = mData.get(position);
holder.textView.setText(item);
}
// Total number of rows
@Override
public int getItemCount() {
return mData.size();
}
// Stores and recycles views as they are scrolled off screen
public class ViewHolder extends RecyclerView.ViewHolder {
TextView textView;
ViewHolder(View itemView) {
super(itemView);
textView = itemView.findViewById(R.id.textView);
}
}
}
```
**Step 4: Initialize RecyclerView**
In your activity or fragment, initialize the RecyclerView and set the adapter.
```
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
MyRecyclerViewAdapter adapter;
List<String> data;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialize data
data = new ArrayList<>();
for (int i = 1; i <= 100; i++) {
data.add("Item " + i);
}
// Set up RecyclerView
recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
adapter = new MyRecyclerViewAdapter(this, data);
recyclerView.setAdapter(adapter);
}
}
```
## Conclusion
RecyclerView is a powerful tool for building efficient and flexible lists in Android applications. By understanding and implementing the basics, along with some advanced techniques, you can create rich, interactive lists that provide a great user experience. Mastering RecyclerView will greatly enhance your Android development skills and allow you to build more dynamic and responsive applications.

Choose a pre-trained large language model, such as BERT, GPT-3, etc.
### 3.3. Setting Fine-tuning Parameters
Set hyperparameters such as learning rate, training epochs, batch size, etc.
### 3.4. Fine-tuning Process
Load the pre-trained model and weights, modify the model according to the task requirements, select an appropriate loss function and optimizer, and perform fine-tuning training.
## 4. RLHF and Fine-tuning with Reinforcement Learning
RLHF is a method that uses human feedback as a reward signal to train reinforcement learning models.
### 4.1. Fine-tuning Language Models with Supervised Data
Adjust the parameters of the pre-trained model using annotated data.
### 4.2. Training a Reward Model
The reward model evaluates the quality of text sequences, and the training data consists of text sequences generated by multiple language models.
### 4.3. Training an RL Model
In the reinforcement learning framework, define the state space, action space, policy function, and value function. Use the policy function to select the next action to maximize cumulative rewards.
## 5. Applications and Methods of Fine-tuning
Fine-tuning large models can be done through full fine-tuning and parameter-efficient fine-tuning (PEFT).
### 5.1. Full Fine-tuning
Adjust all parameters of the pre-trained model using data from a specific task.
### 5.2. Parameter-Efficient Fine-tuning (PEFT)
Achieve efficient transfer learning by minimizing the number of fine-tuned parameters and computational complexity. The main methods include:
- **LoRA**: Introduces low-rank matrices to approximate full parameter fine-tuning of the pre-trained model, significantly reducing computational cost and storage requirements.
- **Adapter Tuning**: Designs adapter structures and embeds them into the Transformer, only fine-tuning the newly added adapter structures while keeping the original model parameters fixed.
- **Prefix Tuning**: Adds learnable virtual tokens as a prefix to the input, only updating the prefix parameters while keeping the rest of the Transformer fixed.
- **Prompt Tuning**: Adds prompt tokens at the input layer, a simplified version of Prefix Tuning, without the need for MLP adjustments.
- **P-Tuning**: Converts prompts into learnable embedding layers and processes them with MLP+LSTM, addressing the impact of prompt construction on downstream task performance.
- **P-Tuning v2**: Adds prompt tokens at multiple layers, increasing the number of learnable parameters and having a more direct impact on model predictions.
These techniques have their own characteristics and are suitable for different application scenarios and computational resource constraints. Choosing the appropriate Fine-tuning technique can significantly improve the model's performance on specific tasks while reducing training time and cost.
## 6. Latest Research Advances in Fine-tuning
In recent years, with the rapid development of deep learning technology, Fine-tuning techniques have also been evolving and innovating. This section will introduce some of the latest research advances in Fine-tuning, providing valuable references for research and applications in related fields.
### 6.1. Adaptive Optimal Fine-tuning Strategy
Traditional Fine-tuning methods often use fixed strategies, such as updating the entire model or only the last few layers. However, this "one-size-fits-all" strategy may not be suitable for all tasks. Recent research has proposed an adaptive optimal fine-tuning strategy that can automatically determine the best fine-tuning layers and update intensity based on the task's complexity and data distribution. This strategy not only improves the model's performance on specific tasks but also enhances its generalization ability.
### 6.2. Cross-modal Fine-tuning
With the widespread application of multi-modal data, achieving cross-modal model fine-tuning has become an important research direction. Recent research has proposed cross-modal Fine-tuning techniques that can integrate data from different modalities (such as images, text, audio, etc.) for joint model fine-tuning. This approach allows the model to learn richer and more diverse feature representations, thereby improving performance on cross-modal tasks.
### 6.3. Meta-learning Assisted Fine-tuning
Meta-learning is a learning paradigm aimed at enabling models to quickly adapt to new tasks. Combining meta-learning with Fine-tuning can achieve more efficient and flexible model fine-tuning. Meta-learning assisted Fine-tuning techniques train models to quickly adapt across multiple tasks, learning more general and robust fine-tuning strategies. This technique can quickly find suitable fine-tuning parameters when facing new tasks, improving model performance.
### 6.4. Explainability and Visualization of Fine-tuning
To better understand and explain the changes in models during Fine-tuning, recent research has focused on the explainability and visualization of model fine-tuning. Visualization techniques can intuitively display the feature changes and learning processes of models during fine-tuning, helping researchers better understand the internal mechanisms of models. Additionally, explainability research helps identify potential biases and errors, improving model credibility and safety.
## 7. Application Scenarios of Fine-tuning
1. **Transfer Learning**: When facing a new task, training a model from scratch may require a lot of time and computational resources. Fine-tuning allows for quick adaptation to new tasks based on a pre-trained model, saving significant resources. For example, in image classification tasks, a model pre-trained on a large-scale image dataset (such as ImageNet) can be fine-tuned on a specific domain's image dataset to improve classification performance in that domain.
2. **Domain Adaptation**: When a model needs to transfer from one domain to another, Fine-tuning can help the model quickly adapt to the new domain's data distribution. For example, in natural language processing tasks, a model pre-trained on a large-scale text corpus can quickly adapt to specific domain tasks such as text classification and sentiment analysis through Fine-tuning.

1,919,788 | Deploying and Managing Applications with Flux: A Technical Guide | Flux is a powerful tool for managing and automating the deployment and configuration of applications... | 0 | 2024-07-11T13:38:08 | https://dev.to/platform_engineers/deploying-and-managing-applications-with-flux-a-technical-guide-o6a | Flux is a powerful tool for managing and automating the deployment and configuration of applications and infrastructure within Kubernetes clusters. This blog post will delve into the technical aspects of deploying and managing applications using Flux, covering key concepts, setup, and configuration.
### Core Concepts
Before diving into the deployment and management of applications, it is essential to understand the core concepts of Flux. Flux is built around the principles of GitOps, which involves managing infrastructure and applications declaratively and version-controlled in a Git repository. This approach ensures that the deployed environment matches the state specified in the repository, promoting a declarative and version-controlled approach to operations.
### Setting Up Flux
To get started with Flux, you need a Kubernetes cluster and a GitHub personal access token with repository permissions. You can use Kubernetes kind for a local development environment. For production use, it is recommended to have a dedicated GitHub account for Flux and use fine-grained access tokens with the minimum required permissions.
### Installing the Flux CLI
The Flux command-line interface (CLI) is used to bootstrap and interact with Flux. You can install the CLI using Homebrew by running the following command:
```bash
brew install fluxcd/tap/flux
```
For other installation methods, refer to the CLI install documentation.
### Bootstrapping Flux
To bootstrap Flux onto your Kubernetes cluster, you need to export your GitHub personal access token and username:
```bash
export GITHUB_TOKEN=<your-token>
export GITHUB_USER=<your-username>
```
Then, run the bootstrap command:
```bash
flux bootstrap github \
--owner=$GITHUB_USER \
--repository=fleet-infra \
--branch=main \
--path=./clusters/my-cluster \
--personal
```
This command creates a Git repository, adds Flux component manifests to the repository, deploys Flux components to your Kubernetes cluster, and configures Flux components to track the specified path in the repository.
### Cloning the Git Repository
Clone the `fleet-infra` repository to your local machine:
```bash
git clone https://github.com/$GITHUB_USER/fleet-infra
cd fleet-infra
```
### Adding a Podinfo Repository to Flux
Create a GitRepository manifest pointing to the podinfo repository’s master branch:
```bash
flux create source git podinfo \
--url=https://github.com/stefanprodan/podinfo \
--branch=master \
--interval=1m \
--export > ./clusters/my-cluster/podinfo-source.yaml
```
Commit and push the `podinfo-source.yaml` file to the `fleet-infra` repository:
```bash
git add -A && git commit -m "Add podinfo GitRepository"
git push
```
### Customizing Podinfo
To customize the podinfo application, you can create a Kustomization manifest:
```yaml
apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
name: podinfo
namespace: flux-system
spec:
interval: 1m
sourceRef:
kind: GitRepository
name: podinfo
path: ./clusters/my-cluster
```
### Managing Applications with Flux
Flux provides a range of features for managing applications, including continuous deployment and progressive delivery. Continuous deployment involves automatically deploying code changes to production once they have passed through automated testing. Progressive delivery builds on continuous deployment by gradually rolling out new features or updates to a subset of users, allowing developers to test and monitor the new features in a controlled environment and make necessary adjustments before releasing them to everyone.
### Conclusion
In this technical guide, we have covered the key concepts, setup, and configuration of Flux for deploying and managing applications. Flux provides a powerful toolset for managing and automating the deployment and configuration of applications and infrastructure within Kubernetes clusters, promoting a declarative and version-controlled approach to operations. By following these steps, you can effectively [utilize Flux to streamline your application](https://platformengineers.io/blog/continuous-delivery-using-git-ops-principles-with-flux-cd/) management and deployment processes. | shahangita | |

1,919,790 | Short-Circuiting Conditions in JavaScript: The Ternary Operator ES6 | Sure! Here is a comprehensive article on conditional (ternary) operators in JavaScript. ... | 0 | 2024-07-11T13:40:46 | https://dev.to/fwldom/short-circuiting-conditions-in-javascript-the-ternary-operator-es6-1b12 | javascript, web, es6, english | Sure! Here is a comprehensive article on conditional (ternary) operators in JavaScript.
## Short-Circuiting Conditions in JavaScript: The Ternary Operator
In JavaScript, making decisions based on conditions is a fundamental part of writing dynamic and responsive code. One of the most concise and efficient ways to implement conditional logic is through the use of the ternary operator. This operator provides a compact syntax to execute one of two expressions based on a given condition. In this article, we will explore how to use the ternary operator, its syntax, benefits, and some practical examples.
### Understanding the Ternary Operator
The ternary operator is the only JavaScript operator that takes three operands. It's also known as the conditional operator because it operates based on a condition. The general syntax of the ternary operator is:
```javascript
condition ? expressionIfTrue : expressionIfFalse;
```
Here's a breakdown of its components:
- **condition**: This is a boolean expression that evaluates to either `true` or `false`.
- **expressionIfTrue**: This expression is executed if the condition is `true`.
- **expressionIfFalse**: This expression is executed if the condition is `false`.
### Basic Example
Let's start with a simple example to understand how the ternary operator works:
```javascript
let age = 18;
let canVote = age >= 18 ? "Yes, you can vote." : "No, you cannot vote yet.";
console.log(canVote); // Output: Yes, you can vote.
```
True ? (istrue) : (isfalse) works in php
In this example, the condition `age >= 18` is evaluated. Since `age` is 18, the condition is `true`, so the expression `"Yes, you can vote."` is executed and assigned to `canVote`.
### Benefits of Using the Ternary Operator
1. **Conciseness**: The ternary operator provides a way to write conditional statements in a single line, making the code more compact and often easier to read for simple conditions.
2. **Improved Readability**: When used appropriately, it can make the code cleaner and more straightforward compared to using multiple lines of `if-else` statements.
3. **Efficiency**: The ternary operator can be faster in execution compared to traditional `if-else` statements, although the difference is typically negligible for most applications.
### Nested Ternary Operators
Ternary operators can be nested to handle more complex conditions. However, excessive nesting can reduce readability, so it should be used sparingly:
```javascript
let score = 85;
let grade = score >= 90 ? "A" :
score >= 80 ? "B" :
score >= 70 ? "C" :
score >= 60 ? "D" : "F";
console.log(grade); // Output: B
```
In this example, multiple conditions are evaluated to determine the grade based on the score.
### Practical Applications
#### Default Values
The ternary operator can be useful for setting default values:
```javascript
let userColor = "blue";
let defaultColor = userColor ? userColor : "black";
console.log(defaultColor); // Output: blue
```
If `userColor` is defined, `defaultColor` will be set to `userColor`. Otherwise, it will fall back to `"black"`.
#### Conditional Rendering
In front-end development, the ternary operator is often used for conditional rendering:
```javascript
let isLoggedIn = true;
let welcomeMessage = isLoggedIn ? "Welcome back!" : "Please log in.";
console.log(welcomeMessage); // Output: Welcome back!
```
### Considerations and Best Practices
1. **Readability**: While the ternary operator is concise, it's important not to overuse it. For complex conditions, traditional `if-else` statements may be more readable.
2. **Debugging**: Debugging nested ternary operators can be challenging. Consider breaking down complex conditions into multiple statements.
3. **Consistency**: Use ternary operators consistently in your codebase to maintain a uniform coding style.
### Conclusion
The ternary operator is a powerful tool in JavaScript for writing concise and readable conditional expressions. By understanding its syntax and appropriate usage, you can leverage this operator to make your code more efficient and maintainable. However, like any tool, it should be used judiciously to avoid compromising the readability and clarity of your code.
---
By mastering the ternary operator, you can write more elegant and streamlined JavaScript code, making your applications more efficient and easier to maintain. | fwldom |

## What is RxJS?
RxJS is a library for composing asynchronous and event-based programs using Observables. Observables are a powerful way to manage asynchronous data streams, allowing you to model data that changes over time, such as user inputs, animations, or data fetched from a server.
In essence, RxJS helps you manage complexity in your applications by providing a robust and declarative approach to handling asynchronous operations.
## Why Use RxJS in Angular?
Angular incorporates RxJS to handle various asynchronous tasks like HTTP requests, event handling, and more. Here are some key reasons to use RxJS in Angular:
- **Declarative Code**: RxJS allows you to write declarative code, making it easier to understand and maintain.
- **Powerful Operators**: With a wide array of operators, you can perform complex data transformations and compositions with ease.
- **Asynchronous Stream Handling**: RxJS makes handling asynchronous data streams straightforward and efficient.
- **Integration with Angular**: Angular's HttpClient and Reactive Forms are built on top of RxJS, making it essential for modern Angular development.
## Setting Up RxJS in an Angular Project
Setting up RxJS in an Angular project is straightforward, as it comes pre-installed with Angular. However, if you need to install RxJS separately, you can do so using npm:
```bash
npm install rxjs
```
You can then import RxJS in your Angular components or services:
```typescript
import { Observable } from 'rxjs';
import { map, filter } from 'rxjs/operators';
```
## Understanding Observables
An Observable is a data producer that emits values over time. You can think of an Observable as a stream of data that you can observe and react to.
### Creating an Observable
To create an Observable, you can use the `Observable` constructor or various creation functions provided by RxJS:
```typescript
import { Observable } from 'rxjs';
// Using Observable constructor
const observable = new Observable(observer => {
observer.next('Hello');
observer.next('World');
observer.complete();
});
// Using creation function
import { of } from 'rxjs';
const observableOf = of('Hello', 'World');
```
### Subscribing to an Observable
To consume the values emitted by an Observable, you need to subscribe to it:
```typescript
observable.subscribe({
next(value) {
console.log(value);
},
error(err) {
console.error('Error:', err);
},
complete() {
console.log('Completed');
}
});
```
### Output
```
Hello
World
Completed
```
## Common RxJS Operators
Operators are functions that enable you to transform, filter, and combine Observables. Here are some commonly used RxJS operators:
### `map`
Transforms each value emitted by the source Observable:
```typescript
import { of } from 'rxjs';
import { map } from 'rxjs/operators';
of(1, 2, 3).pipe(
map(value => value * 2)
).subscribe(console.log); // Outputs: 2, 4, 6
```
### Output
```
2
4
6
```
### `filter`
Filters values emitted by the source Observable:
```typescript
import { of } from 'rxjs';
import { filter } from 'rxjs/operators';
of(1, 2, 3, 4).pipe(
filter(value => value % 2 === 0)
).subscribe(console.log); // Outputs: 2, 4
```
### Output
```
2
4
```
### `mergeMap`
Projects each source value to an Observable and merges the resulting Observables into one:
```typescript
import { of } from 'rxjs';
import { mergeMap } from 'rxjs/operators';
of('Hello', 'World').pipe(
mergeMap(value => of(`${value}!`))
).subscribe(console.log); // Outputs: Hello!, World!
```
### Output
```
Hello!
World!
```
## Practical Examples
### Example 1: Handling HTTP Requests
Handling HTTP requests in Angular is a common use case for RxJS. Angular's HttpClient service is built on top of RxJS, making it easy to work with asynchronous HTTP data.
```typescript
import { HttpClient } from '@angular/common/http';
import { Component, OnInit } from '@angular/core';
import { Observable } from 'rxjs';
@Component({
selector: 'app-data',
template: `<div *ngFor="let item of data">{{ item }}</div>`
})
export class DataComponent implements OnInit {
data: any[];
constructor(private http: HttpClient) {}
ngOnInit() {
this.fetchData().subscribe(data => this.data = data);
}
fetchData(): Observable<any[]> {
return this.http.get<any[]>('https://api.example.com/data');
}
}
```
### Output
```
Item 1
Item 2
Item 3
...
```
### Example 2: Reactive Forms
RxJS is also integral to Angular's Reactive Forms. You can use it to handle form control changes and validation.
```typescript
import { Component } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';
import { debounceTime } from 'rxjs/operators';
@Component({
selector: 'app-form',
template: `
<form [formGroup]="form">
<input formControlName="search">
</form>
<p>{{ result }}</p>
`
})
export class FormComponent {
form: FormGroup;
result: string;
constructor(private fb: FormBuilder) {
this.form = this.fb.group({
search: ['']
});
this.form.get('search').valueChanges.pipe(
debounceTime(300)
).subscribe(value => {
this.result = value;
});
}
}
```
### Output
```
(User types 'hello')
hello
(User types 'world')
world
```
### Example 3: Real-Time Data Streams
RxJS excels at handling real-time data streams, such as WebSocket connections.
```typescript
import { Injectable } from '@angular/core';
import { webSocket } from 'rxjs/webSocket';
@Injectable({
providedIn: 'root'
})
export class WebSocketService {
private socket$ = webSocket('wss://echo.websocket.org');
sendMessage(msg: string) {
this.socket$.next(msg);
}
getMessages() {
return this.socket$.asObservable();
}
}
```
```typescript
import { Component, OnInit } from '@angular/core';
import { WebSocketService } from './web-socket.service';
@Component({
selector: 'app-chat',
template: `
<input [(ngModel)]="message">
<button (click)="sendMessage()">Send</button>
<div *ngFor="let msg of messages">{{ msg }}</div>
`
})
export class ChatComponent implements OnInit {
message: string;
messages: string[] = [];
constructor(private wsService: WebSocketService) {}
ngOnInit() {
this.wsService.getMessages().subscribe(msg => this.messages.push(msg));
}
sendMessage() {
this.wsService.sendMessage(this.message);
this.message = '';
}
}
```
### Output
```
(User types 'Hello' and clicks send)
Hello
(User types 'How are you?' and clicks send)
How are you?
```
## Best Practices
- **Avoid Nested Subscriptions**: Use higher-order mapping operators like `mergeMap`, `switchMap`, and `concatMap` to flatten nested Observables.
- **Unsubscribe Properly**: Use `takeUntil` or `unsubscribe` to avoid memory leaks by unsubscribing from Observables when they are no longer needed.
- **Use Async Pipe**: Leverage Angular’s `async` pipe to handle subscriptions and unsubscriptions automatically in templates.
- **Compose Operators**: Chain operators using `pipe` for better readability and maintainability.
## Conclusion
RxJS is a powerful tool for managing asynchronous operations in Angular. By understanding the basics of Observables, operators, and how to integrate RxJS with Angular components and services, you can build efficient, reactive, and maintainable applications. This guide provides a solid foundation for getting started with RxJS in Angular. Happy coding!

### Search tool
- The search tool allows you to quickly find specific text within the PDF, simplifying the process of locating information without the need for manual document browsing.
### Print document tool
- Using the print tool, users can easily print PDFs directly from the PDF Viewer, allowing them to produce physical copies of their documents.
### Annotation tools
- **Text markups:** Use text markup tools to highlight important text, underline headers, strike through text to be removed, or use squiggly lines to mark errors. These tools help review document contents. You can also customize the color and opacity of the text markups using the toolbar’s editing tools.
- **Shapes:** Use shape tools to draw lines, rectangles, circles, arrows, polygons, and polylines to annotate PDF documents. You can also customize these shapes in terms of color, opacity, and thickness.
- **Ink and ink eraser:** Use the ink tool for freehand drawing on the PDF, with options to customize ink color and thickness. The ink eraser tool allows users to correct any mistakes made while drawing.
- **Free text:** Use the free text tool to add text annotations anywhere on the PDF. The toolbar’s editing tools allow customization of text color, size, opacity, background, and border.
- **Sticky note:** Use the sticky note tool to add notes to PDF for comments or reminders. You can also customize the icon, color, opacity, and other properties using the editing tools in the toolbar.
- **Stamp:** Use the stamp tool to add pre-defined or custom images as stamps to PDF documents, with the ability to customize their opacity.
**Note:** The appearance, visibility, positioning, and user experience of specific tools in the toolbar may vary between mobile and desktop platforms. This variation is based on usability considerations and available screen space, ensuring optimal functionality for each platform.
## Toolbar customization
Depending on the available screen space, the .NET MAUI PDF Viewer organizes its tools into multiple or multilevel toolbars on mobile and desktop platforms.
For example, view options, navigation tools, search, and print options are available in the primary or top toolbar. In contrast, annotation tools are available in the secondary or bottom toolbar, and so on. Users need to access specific toolbars to access the corresponding toolbar items.
Let’s see how to customize and access toolbars and their items using code-behind APIs.
### Hide all the toolbars
In specific scenarios, you should hide all the toolbars in the .NET MAUI PDF Viewer to display the document in full-view mode or use customized toolbars based on your app needs. You can hide all toolbars by setting the [ShowToolbars](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_ShowToolbars "ShowToolbars property of the .NET MAUI PDF Viewer") property to **False**. Refer to the following code example.
**XAML**
```xml
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="PdfViewerDemo.MainPage"
xmlns:syncfusion="clr-namespace:Syncfusion.Maui.PdfViewer;assembly=Syncfusion.Maui.PdfViewer">
<syncfusion:SfPdfViewer x:Name="PdfViewer" ShowToolbars="False"/>
</ContentPage>
```
**C#**
```csharp
SfPdfViewer PdfViewer = new SfPdfViewer();
PdfViewer.ShowToolbars = false;
```
**Note:** For more details, refer to the [GitHub demo for hiding the toolbar in the .NET MAUI PDF Viewer](https://github.com/SyncfusionExamples/maui-pdf-viewer-examples/tree/master/Toolbar%20customization/HideToolbars "Hiding the toolbar in the .NET MAUI PDF Viewer GitHub demo").
### Hide specific toolbars
Sometimes, you might need to hide specific toolbars instead of all. This can be useful if you want to simplify the user interface by removing unnecessary tools or creating a more focused environment for certain tasks. The [Toolbars](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_Toolbars "Toolbars property of the .NET MAUI PDF Viewer") collection property in the PDF Viewer allows us to hide a specific toolbar by using its index or name.
Let’s see them in detail!
#### Hide toolbars by index
If you know the position of the toolbar you want to hide within the [Toolbars](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html#Syncfusion_Maui_PdfViewer_SfPdfViewer_Toolbars "Toolbars property of the .NET MAUI PDF Viewer") collection, you can access and hide it using its index. For example, you can use the following code to hide the first and second toolbars in the collection.
**C#**
```csharp
if (PdfViewer.Toolbars.Count > 1)
{
PdfViewer.Toolbars[0].IsVisible = false;
PdfViewer.Toolbars[1].IsVisible = false;
}
```
#### Hide toolbars by name
In scenarios where you need to hide toolbars based on their specific functionality, using their names is more practical and flexible. This can be achieved by passing the toolbar’s name to the [GetByName](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.ToolbarCollection.html#Syncfusion_Maui_PdfViewer_ToolbarCollection_GetByName_System_String_ "GetByName (String) method of the .NET MAUI PDF Viewer") method for toolbar collection.
For example, you can use the following code to hide the bottom toolbar in the PDF Viewer, which contains annotation tools on the mobile platform.
**C#**
```csharp
// Get the bottom toolbar in the PDF Viewer that contains annotation tools on mobile platforms.
Syncfusion.Maui.PdfViewer.Toolbar? bottomToolbar = PdfViewer.Toolbars?.GetByName("BottomToolbar");
if (bottomToolbar != null)
{
// Hide the toolbar.
bottomToolbar.IsVisible = false;
}
```
To find the names and purposes of other toolbars, you can refer to [this documentation](https://help.syncfusion.com/maui/pdf-viewer/toolbar#mobile-toolbar-names "Working with toolbar in .NET MAUI PDF Viewer").
Alternatively, you can identify a toolbar’s name using its [Name](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.Toolbar.html#Syncfusion_Maui_PdfViewer_Toolbar_Name "Name property of the .NET MAUI PDF Viewer") property within the [Toolbar](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.Toolbar.html "Toolbar property of the .NET MAUI PDF Viewer") object. Refer to the following code to find the name of the first toolbar.
**C#**
```csharp
if (PdfViewer.Toolbars != null && PdfViewer.Toolbars.Count > 0)
{
// Get the name of the first toolbar.
string name = PdfViewer.Toolbars[0].Name;
}
```
## Toolbar items customization
In addition to customizing the visibility of toolbars, you can customize the items within each toolbar of the .NET MAUI PDF Viewer. This includes adding new items, removing existing ones, or rearranging their order to suit your app’s workflow better.
### Add items to the toolbar
To add new items to a toolbar, we can use the [Items](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.Toolbar.html#Syncfusion_Maui_PdfViewer_Toolbar_Items "Items property of the .NET MAUI PDF Viewer") collection of the Toolbar object. Here’s an example of converting a button to a [ToolbarItem](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.ToolbarItem.html "ToolbarItem class of the .NET MAUI PDF Viewer") object and adding it to the top toolbar.
**C#**
```csharp
/// <summary>
/// Add a save button to the PDF Viewer toolbar.
/// </summary>
void AddSaveDocumentButton()
{
Button saveDocumentButton = new Button
{
Text = "Save",
Padding = 10
};
saveDocumentButton.Clicked += SaveDocumentClicked;
// Create toolbar item.
Syncfusion.Maui.PdfViewer.ToolbarItem toolbarItem = new Syncfusion.Maui.PdfViewer.ToolbarItem(saveDocumentButton, "SaveDocumentButton");
// Get the top toolbar of the PDF Viewer that contains primary tools on mobile platforms.
Syncfusion.Maui.PdfViewer.Toolbar? topToolbar = PdfViewer.Toolbars?.GetByName("TopToolbar");
if (topToolbar != null)
{
// Add the save button to the toolbar.
topToolbar?.Items?.Add(toolbarItem);
}
}
private void SaveDocumentClicked(object? sender, EventArgs e)
{
// Write your logic to save the document.
}
```
Refer to the following image.

<figcaption>Adding save tool in the .NET MAUI PDF Viewer's toolbar</figcaption>
</figure>
### Remove items from the toolbar
If you need to remove specific items from a toolbar, you can do so from the [Items](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.Toolbar.html#Syncfusion_Maui_PdfViewer_Toolbar_Items "Items property of the .NET MAUI PDF Viewer") collection. You can remove them either by index or by name.
#### Remove item by index
Removing an item by its index is straightforward. Here’s how to remove an item from the top toolbar at a specific index.
**C#**
```csharp
// Get the top toolbar of the PDF Viewer that contains annotation tools on mobile platforms.
Syncfusion.Maui.PdfViewer.Toolbar? topToolbar = PdfViewer.Toolbars?.GetByName("TopToolbar");
if (topToolbar != null)
{
// Get the first item from the toolbar.
Syncfusion.Maui.PdfViewer.ToolbarItem? firstItem = topToolbar.Items?[0];
if (firstItem != null)
{
// Remove the first item from the toolbar.
topToolbar?.Items?.Remove(firstItem);
}
}
```
#### Remove item by name
Removing an item by its name provides a targeted approach, particularly useful when managing named items within the toolbar. Here’s how to remove the outlines tool from the primary toolbar on desktop platforms using its name.
```csharp
// Get the primary toolbar of the PDF Viewer that contains primary tools on desktop platforms.
Syncfusion.Maui.PdfViewer.Toolbar? primaryToolbar = PdfViewer.Toolbars?.GetByName("PrimaryToolbar");
if (primaryToolbar != null)
{
// Get the outline from the toolbar.
Syncfusion.Maui.PdfViewer.ToolbarItem? outlineTool = primaryToolbar.Items?.GetByName("Outline"); ;
if (outlineTool != null)
{
// Remove the tool from the toolbar.
primaryToolbar?.Items?.Remove(outlineTool);
}
}
```
Refer to the following images.

It provides a concise language so you can create scripts or integrate into your application and consume Google Cloud services as Drive, Sheet or Gmail
In this post series I'll (try) to explain the origin, aim and how to use it with several real examples
## Requirement
- A Google account
- Java 11+ and Groovy 4.x installed
- A Google credentials file (more details above)
## Example
With Groogle you can create a script, for example, to list all the files in your `Drive`:
```
groogle = GroogleBuilder.build {
withOAuthCredentials {
applicationName 'test'
scopes DriveScopes.DRIVE
usingCredentials "client_secret.json"
storeCredentials true
}
}
groogle.with {
service(DriveService).with {
findFiles {
eachFile {
println "$id = $file.name"
}
}
}
}
```
## Origin
A few years ago I was fascinated about how easily you can write your own DSL using ApacheGroovy so I started a project called Groogle (Groovy + Google)
I started it using the `com.puravida-software.groogle` maven coordinates but as PuraVida Software company run out, I've decided to rewrite/improve it under the new `es.edn.groogle` coordinates
## First steps
Before to start you need to have a Google Cloud account and a project created, say `QuickStart` for example
Create an Oauth 2.0 credentials (service credentials will be covered in another post):
Download the `.json` file but **don't share them nor store in your repo**. For our examples this file will be called `client_secret.json`
## First script
In the same folder you downloaded the json create a `example.groovy` file:
```
import com.google.api.services.sheets.v4.SheetsScopes
import com.google.api.services.drive.DriveScopes
import es.edn.groogle.*
@Grab("es.edn:groogle:4.0.0-rc4")
@GrabConfig(systemClassLoader=true)
groogle = GroogleBuilder.build {
withOAuthCredentials {
applicationName 'test'
scopes DriveScopes.DRIVE, SheetsScopes.SPREADSHEETS
usingCredentials "client_secret.json"
storeCredentials true
}
}
groogle.with {
service(DriveService).with {
findFiles {
eachFile {
println "$id = $file.name"
}
}
}
}
```
in a terminal console execute:
`groovy example.groovy`
if all goes well a browser will be opened and you need to indicate which Google account you want to use
and allow access to the application
Now you can close the browser and see how the script was able to iterate over your files
## Next
In following posts we'll see how to create or download files from your Drive, create and modify Sheets or send emails

1,919,817 | How Random Are Random Number Generators? | Hey Good People Today lets explore the randomness of random number generator in our computers ... | 0 | 2024-07-11T14:01:13 | https://dev.to/something_something_64b2a/how-random-are-random-number-generators-1eid |
Hey Good People
Today lets explore the randomness of random number generator in our computers
# What is Random Number
So Let's start with a predicting a number and you try to answer it by yourself before reading further
#### Guess a number from 1-10
If you have guessed 7 your like 45% other who would have done that
So does picking 7 make it random ??
Well a number can't be random , I mean if you say a number and ask me is it random it's not a valid question actually
Randomnees is measured based on a sequence of number
like if i again ask you to pick a number from 1-10 and you pick 7 would be random , I don't know
But if I asked 100 times and you replied 100 times with 7 then i can safely say its not random
So I guess we are clear on what is random numbers its basically a sequence of numbers where I can't tell what would be next
# Our very own Random number generator
So in coding we sometimes need random number. Whats it's application ?
I guess pretty easy application is in Game development like you want to spawn enemies. You just can't spawn them at the same place then the player would get bored . So you need random coordinates for that
Also for lottery ticket allocation or password generator are pretty decent use cases
Most amazing use cases are in cryptography. I mean when you send messages its need to be encrypted there in encryption random number generator will be needed
Now we know where random number are needed.But how to generate them
Each programming language have their own native function and wrapper to generate random number for simplicity we will use only C but in other language basic thinking are the same
# How random is our random number generator
Most random number generators on computers are actually pseudo-random number generators (PRNGs) Detail explanation in next section. This means they use a mathematical formula to generate a sequence of numbers that appears random, but it's not truly random in the strictest sense.
Here's the difference:
True random number generators (TRNGs): These rely on unpredictable physical events like atmospheric noise or radioactive decay to produce randomness. They are more secure and less predictable, but can be slower and more expensive to implement.
Pseudo-random number generators (PRNGs): These are deterministic, meaning they use a formula and an internal state to generate numbers. While the numbers seem random, they can be reproduced if you know the starting state (seed) of the PRNG. These are faster and easier to implement, but not suitable for cryptography or other security-critical applications.
PRNGs are fine for many common uses like games or simulations. However, for things like cryptography where true randomness is essential, TRNGs are the better choice.
# What is Pseudo Random Number then ?
This example uses the Linear Congruential Generator (LCG) method, a common type of PRNG.
Formula:
X_n = (a * X_(n-1) + b) mod m
Where:
X_n: The nth random number in the sequence (0 ≤ X_n < m)
a: Multiplier (positive integer, less than m)
b: Increment (non-negative integer, less than m)
m: Modulus (positive integer)
mod: Modulo operation (remainder after division)
Let's see it in action with small values:
Seed (X_0): 1
Multiplier (a): 2
Increment (b): 1
Modulus (m): 4 (This will limit our random numbers to 0, 1, 2, 3)
Sequence:
X_1 = (2 * X_0 + b) mod m = (2 * 1 + 1) mod 4 = 3
X_2 = (2 * X_1 + b) mod m = (2 * 3 + 1) mod 4 = 7 (since 7 mod 4 = 3)
X_3 = (2 * X_2 + b) mod m = (2 * 3 + 1) mod 4 = 7 (again, repeats because 7 mod 4 = 3)
Explanation:
We see the sequence repeats after just 2 steps (X_2 and X_3 are the same).
This is because for this specific choice of parameters (a, b, and m), the generator only produces 2 unique values (0 and 3) before repeating.
Note:
This is a very basic example. Real-world PRNGs use much larger values for a, b, and m, leading to much longer cycles and more unpredictable sequences.
So Our Code's Random number generator works like this and acutally are not random at all.
You can try [Predict Random Number of JS native random number Generator](https://www.youtube.com/watch?v=-h_rj2-HP2E) to guess JS native random number generator its that easy
# Then why do we use pseudo random number generator ?
Now if you choose the parameters correctly it will take hours if not days for any computer to predict your next number so in practice its useful as they are serving the purpose. I mean who would try to guess where the next enemy in the game will appear for hours rather than playing the game.
# How to create true random number then (like for cryptography at least)?
Upon searching I was about to conclude that Its not possible by software but keep reading for the conclusion
Now true random number can be generated by physical things and can be simulated using code. Like how many electron is emitted from a radioactive element will create randomness. Also the noise of wind is also random
But how can we use it in our PC's?
Well latest x86 processor allows you to create True Random number
`rdrand int _rdrand16_step (unsigned short* val)`
So does cryptrographers uses this kind of method ?
NO
First of all There are services that will give you true random number using physical things like [API for Random Number Generator](https://www.random.org/)
This api gives you true random number from noise in your side. Pretty cool ha.For simplicity you can assume crypthographical random number also depends on such kind of hardware system, you can also read the reference for more info on it
# Why can't we use C lang true random number ?
Lets create a pseudo random number in C/C++
```
#include <cstdlib>
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
// This program will create different sequence of
// random numbers on every program run
// Use current time as seed for random generator
srand(time(0));
for (int i = 0; i < 4; i++)
cout << rand() << " ";
return 0;
}
```
Now its pseudo as we have learned rand() does will repeat it self in finite time.
What if we use `rdseed` we can get true random number but the problem is that intel itself demotivate to use it as its distribution is not optimized.
What does it mean well if you again I asked 1000 people to pick a number from 1-100 and plot the results the result may look like below
So its random but you can see its a gaussian distribution so its not predictable but you can guess the number probability of being in that range make it less random
Intel's built in x86 kind of suggests that there prediction may fall into gaussian distribution.[Godbolt](https://godbolt.org/) this website gives you clear idea of how a compiler works on it run the previous code in it and see the magic
Where the normal random number generator have kind of normal distribution (each have equal probability of appearing) so in that case we can safely use pseudo random number generator for normal purposes
# Conclusion
In conclusion, while computers cannot generate truly random numbers due to their deterministic nature, pseudo-random number generators (PRNGs) are a powerful tool for many applications. By carefully choosing parameters, PRNGs can produce long and unpredictable sequences of numbers that are sufficient for most purposes, like game development and simulations.
However, for cryptography and other security-critical applications where true randomness is essential, alternative methods are needed. These can include using hardware-based random number generators (TRNGs) or utilizing online services that gather randomness from physical phenomena.
Remember, understanding the limitations of PRNGs is crucial for using them effectively. They are a valuable tool, but for true randomness, we need to look beyond the realm of software and into the physical world.

I've found a neat way to add an undo feature to Git.
As you all know, Git itself relies on the `.git` folder, which contains all versioning information and metadata for your repository. Every Git command you run, from `git add` to `git commit`, modifies files within this `.git` folder. By using Mercurial (`hg`) to version control the `.git` folder itself, `rgc` (short for risky-git-command) allows you to save these changes and easily revert to this state if something goes wrong.
Here's how it adds in your workflow:
`$ rgc do
$ <perform some risky git command>
Messed up?
$ rgc undo`
Whether you're just starting with Git or have been using it for years, `rgc` can be a valuable tool to aid you in difficult situations.
This is a shell script (`rgc`) that's only 1KB in size. It's designed to be efficient and easy to use. For ubuntu users, I've built a `.deb` package, you can install using `dpkg -i rgc.deb`
Check the repo on Github: https://github.com/0xdsaini/rgc | devesh525s | |

1,919,821 | Create a better talent strategy with FlexC’s AI talent platform | Millennials and Gen-Zs apply and choose to stay in an organization based on the complete experience,... | 0 | 2024-07-11T14:04:12 | https://dev.to/malika_dhingra_3a568d8053/create-a-better-talent-strategy-with-flexcs-ai-talent-platform-3c2h | ai | Millennials and Gen-Zs apply and choose to stay in an organization based on the complete experience, not just the compensation. Finding the right talent, providing them with the right candidate experience, and focusing on their overall growth puts a lot on the plate of human resources. Not to mention the numerous layers in our current hiring process that stretch the time it takes to onboard talent.
Also, there are various challenges to outsourcing independent talent, such as hidden markups and complicated processes. AI talent platforms address and fill these gaps. FlexC is an AI talent platform that leverages the power of artificial intelligence and addresses the pain points hiring managers face. FlexC helps managers to streamline their recruitment processes, enhance candidate selection, and empower managers to make better-informed decisions. FlexC helps companies streamline independent and full-time hiring and keeps the process transparent with no hidden fees or markups.
## **How FlexC’s AI helps your business tailor your talent strategy?**
## **Smarter AI evaluation**
A recent Mckinsey study revealed that one of the major reasons for employees to leave their current roles was a lack of career growth. While hiring managers and ATS (applicant tracking systems) can help you find the best resumes out of the pile of applicants, there are still instances where managers end up hiring over or under-qualified candidates for a position.
The AI at FlexC resolves this issue by sharing a list of applications according to the role progression. It means the candidates who have spent reasonable time in their current role and have enough experience to promote to the next level will show at the top.
Through FlexC’s AI algorithms, you will be able to select more suitable candidates.

This time we will... | 0 | 2024-07-11T15:15:41 | https://dev.to/miga/titanium-news-19-3oig | titaniumsdk, mobile, javascript, news | <small>Older posts can be found [here](https://dev.to/miga).</small>
# Intro
It's `Titanium News` time again! This time we will look at 12.3.1.GA, 12.4.0.RC, module updates and how to use ChatGPT to create Titanium iOS modules.
# Titanium 12.3.1.GA
The latest GA release 12.3.1 was published in June and fixed some issues that people reported with 12.3.0. The main part was related to Apples new privacy requirements in case you are using filesystem APIs like `createdAt()` or `modifiedAt()`. Support for iOS multi-scene apps has been removed for now as it introduced some issues for normal apps. It will be revised in future releases.
On the Android side you can now use `switchCamera` again when your app is not using `useCameraX` and `touchFeedbackColor` is fixed for BottomNavigation tabs.
One new features is also included: You can use platform dependend `<id>` blocks in your tiapp.xml now:
```xml
<id platform="android">com.miga.test_android</id>
<id>com.miga.test</id>
```
We all have an app where you had to switch ids and now you can have it in one tiapp.xml file!
# Titanium 12.4.0.RC
A first test version of Titanium 12.4.0 was released this week. Since Google updated their store requirement a bit early you have to target Android API level 34 for new apps now. You can always update the level by hand by adding this to your tiapp.xml:
```xml
<android>
<manifest>
<uses-sdk android:targetSdkVersion="34"/>
</manifest>
</android>
```
but in case you are using `BroadcastReceiver` in your app you have to update to 12.4.0.RC as it required a code change. So in case you see this error `One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified when a receiver isn't being registered exclusively for system broadcasts` when your build your app for targetSdkVersion 34 you have to update the Titanium SDK.
But 12.4.0 doesn't just include that change, it also has some nice new features and bug fixes.
* add swipe actions support for Ti.UI.TableView ([video](https://github.com/tidev/titanium-sdk/pull/14065))
* Android: add moveToBackground method
* Android: option to hide scrollbars in a WebView
* Android: missing Event.remove() method was added
* Android: parity for OptionBar color properties
* Android: track colors in a Switch
* Android: text alignment for date pickers
* Android: video playback speed
* Android: `defaultLang` option in tiapp.xml (in case you run an app that doesn't have EN as the first language)
* iOS: iOS 17 symbol effects ([video](https://github.com/tidev/titanium-sdk/pull/13982))
* iOS: backgroundColor for RefreshControl
* iOS: overrideUserInterfaceStyle a Picker
# Preview
The task list for the next big Titanium release will include iOS 18 support and Android API level 34 by default. There are still plenty of pull requests in the queue https://github.com/tidev/titanium-sdk/pulls like "flatten ListView layout" for Android that improves the performance in complex template setups and bigger changes like the upgrade to gradle 8.
If you find bugs or need a feature feel free to create an issue at https://github.com/tidev/titanium-sdk/issues so Titanium developers can look at it.
# Modules
Module developers have been busy updating their modules and creating some new ones. Here is a quick list of some of those:
* Review dialog: the Android version has been updated to use the latest play store library. Make sure to get the latest version from https://github.com/hansemannn/titanium-review-dialog/
* in-app update: same for the Android in-app update module. Go to https://github.com/m1ga/ti.inappupdate and grab the latest version with the latest play store libraries.
* Titanium QR Code generator & scanner: a new iOS version with a cancel button is available at https://github.com/hansemannn/titanium-qrcode
* Screen Recording detector: a new iOS module by [Max87ZA](https://github.com/Max87ZA/) that detects when you do a screen recording on iOS. This was created with help of ChatGPT-o! Check it out at https://github.com/Max87ZA/Ti.ScreenRecordingDetector
* Social Share: another new iOS module for native text and image sharing by [emptybox](https://github.com/emptybox/). Download it from https://github.com/emptybox/SocialShareEBM
* in-app-purchasing: [Hans](https://github.com/hansemannn) updated his in-app payment Android module https://github.com/hansemannn/titanium-iap/ to use the latest play billing API 7.0.0
* ti.animation: The Android Lottie library of https://github.com/m1ga/ti.animation was updated.
* PurgeTSS: @maccesar made a big update v6.3.3 for his PurgeTSS library. Make sure to look at https://purgetss.com/ for all the changes and update with `npm install -g purgetss@latest`.
I'm sure I've missed some :) So feel free to leave a comment for new modules, updates or if you'll need some module updates.
# Spotlight
## Using ChatGPT to create a custom iOS module.
Multiple Titanium users are leveraging ChatGPT to support them in building apps and modules. As mentioned in the last Titanium News there is also a Titanium ChatGPT copilot at https://chat.openai.com/g/g-ZNwI6zmBi-titanium-copilot.
The following are the prompts that were used to create the Social share module:
> Creating a module for Titanium (Appcelerator) to share an image via text, email, Instagram, Facebook, or save to the local gallery requires several steps. Below is a detailed guide and sample code for creating an iOS module compatible with the latest version of Xcode and Swift.
To get basic instructions to setup a new module, the first code and compile instructions.
> what do I name the new swift file I'm creating and where should it be placed?
Returned detailed instructions where you have to place the files in your directory and what to put in each file.
Even switching to Objectiv-C with
> If I want to use obj-c what would the code look like?
was answered right away with new code.
Even errors like
> I'm having issues with this: - (void)share:(id)args; - I'm getting the following errors: expected ';' at end of declaration list. Expected member name or ';' after declaration specifiers. Type name requires a specifier or qualifier
or
> at UIImage I'm getting this error: Definition of 'TiBlob' must be imported from module 'TitaniumKit.TiBlob' before it is required
were fixed with the results by ChatGPT.
Sometimes it will return old `appc ti` commands but it's easy to use `ti` instead.
Have a look at the full conversation at https://www.fromzerotoapp.com/create-a-titanium-ios-module-with-chatgpt/
If you create some new module leave a comment and I'll feature it next time.
# That's it
If you have feedback or some interesting Titanium SDK apps, modules or widgets you would like to share: get in contact with me or leave a comment and I'll add it to the next `Titanium news`. | miga |

description: How to setup custom Next.js server using Fastify
tags: nextjs, fastify, nodejs, typescript
# published_at: 2024-07-11 14:04 +0000
---
Next.js is an exceptional framework for React applications that comes with a lot of bells and whistles for Server-Side Rendering and Static Site Generation. One of the quickest ways to start writing production-ready React without spending the time on setup.
Next.js comes with its own server that can be used out-of-the-box when starting a brand-new projects.
But what if you need to serve Next.js app from an existing Node server? Or maybe you want to have more flexibility additional flexibility for integrating middleware, handling custom routes, etc?
If that's the case - this post is for you, it covers the setup of custom Next.js server with Fastify, solution for Express.js or plain Node.js server will be similar.
Example project used here is also available as a template on [Github](https://github.com/ilinieja/nextjs-custom-server-with-fastify).
# Initial setup
So imagine you have an existing Fastify project. For the sake of example I have a simple Fastify API [here](https://github.com/ilinieja/nextjs-custom-server-with-fastify/tree/initial). It's initialized from [this great Fastify template](https://github.com/ManUtopiK/vite-fastify-boilerplate) and has a couple of endpoints returning mock data:
- `/_health` - server status
- `/api/pokemons` - Pokemons list
- `/api/stats` - list of Pokemon stats
```typescript
// src/app.ts
import { fastify as Fastify, FastifyServerOptions } from "fastify";
import { POKEMONS, STATS } from "./mocks";
export default (opts?: FastifyServerOptions) => {
const fastify = Fastify(opts);
fastify.get("/_health", async (request, reply) => {
return { status: "OK" };
});
fastify.get("/api/pokemons", async (request, reply) => {
return POKEMONS;
});
fastify.get("/api/stats", async (request, reply) => {
return STATS;
});
return fastify;
};
```
# Adding Next.js app
It's as easy as just generating a new Next.js project using `create-next-app`, I'll do it in `./src` directory:
```bash
cd ./src && npx create-next-app nextjs-app
```
# Handling requests using Next.js
To allow Next.js render pages Fastify needs to pass requests to it.
For this example, I want Next.js to handle all routes under `/nextjs-app`
```typescript
// Path Next.js app is served at.
const NEXTJS_APP_ROOT = "/nextjs-app";
fastify.all(`${NEXTJS_APP_ROOT}*`, (request, reply) => {
// Remove prefix to let Next.js handle request
// like it was made directly to it.
const nextjsAppUrl = parse(
request.url.replace(NEXTJS_APP_ROOT, "") || "/",
true
);
nextjsHandler(request.raw, reply.raw, nextjsAppUrl).then(() => {
reply.hijack();
reply.raw.end();
});
});
```
Next.js also makes requests to get static, client code chunks etc. on `/_next/*` routes, need to pass requests from Fastify to it:
```typescript
// Let Next.js handle its static etc.
fastify.all("/_next*", (request, reply) => {
nextjsHandler(request.raw, reply.raw).then(() => {
reply.hijack();
reply.raw.end();
});
});
```
As a result, complete Fastify routing would look like this:
```typescript
// src/fastify-app.ts
import { fastify as Fastify, FastifyServerOptions } from "fastify";
import { POKEMONS, STATS } from "./mocks";
import nextjsApp from "./nextjs-app";
import { parse } from "url";
const nextjsHandler = nextjsApp.getRequestHandler();
export default (opts?: FastifyServerOptions) => {
const fastify = Fastify(opts);
fastify.get("/_health", async (request, reply) => {
return { status: "OK" };
});
fastify.get("/api/pokemons", async (request, reply) => {
return POKEMONS;
});
fastify.get("/api/stats", async (request, reply) => {
return STATS;
});
// Path Next.js app is served at.
const NEXTJS_APP_ROOT = "/nextjs-app";
fastify.all(`${NEXTJS_APP_ROOT}*`, (request, reply) => {
// Remove prefix to make URL relative to let Next.js handle request
// like it was made directly to it.
const nextjsAppUrl = parse(
request.url.replace(NEXTJS_APP_ROOT, "") || "/",
true
);
nextjsHandler(request.raw, reply.raw, nextjsAppUrl).then(() => {
reply.hijack();
reply.raw.end();
});
});
// Let Next.js handle its static etc.
fastify.all("/_next*", (request, reply) => {
nextjsHandler(request.raw, reply.raw).then(() => {
reply.hijack();
reply.raw.end();
});
});
return fastify;
};
```
Where the `nextjsApp` comes from Next.js initialization here:
```typescript
// src/nextjs-app.ts
import next from "next";
import env from "./env";
export default next({
dev: import.meta.env.DEV,
hostname: env.HOST,
port: env.PORT,
// Next.js project directory relative to project root
dir: "./src/nextjs-app",
});
```
And last but not the least - Next.js app needs to be initialized before starting the server:
```typescript
nextjsApp.prepare().then(() => {
fastifyApp.listen({ port: env.PORT as number, host: env.HOST });
fastifyApp.log.info(`Server started on ${env.HOST}:${env.PORT}`);
});
```
Full server init will look like this:
```typescript
// src/server.ts
import fastify from "./fastify-app";
import logger from "./logger";
import env from "./env";
import nextjsApp from "./nextjs-app";
const fastifyApp = fastify({
logger,
pluginTimeout: 50000,
bodyLimit: 15485760,
});
try {
nextjsApp.prepare().then(() => {
fastifyApp.listen({ port: env.PORT as number, host: env.HOST });
fastifyApp.log.info(`Server started on ${env.HOST}:${env.PORT}`);
});
} catch (err) {
fastifyApp.log.error(err);
process.exit(1);
}
```
# Build updates
Now Next.js app needs to be built before starting the server, so a couple updates in `package.json`:
```json
"scripts": {
"build": "concurrently \"npm:build:fastify\" \"npm:build:nextjs\"",
"build:fastify": "vite build --outDir build --ssr src/server.ts",
"build:nextjs": "cd ./src/nextjs-app && npm run build",
"start": "pnpm run build && node build/server.mjs",
...
```
# Result
With these changes applied, Fastify keeps handling all the routes it initially had:
- `/_health` - server status
- `/api/pokemons` - Pokemons list
- `/api/stats` - list of Pokemon stats
And everything under `/nextjs-app` is handled by Next.js:

# Note on limitations
Vite HMR for the Fastify server became problematic after adding Next.js app - Next.js has separate build setup and it doesn't play well with Vite Node plugin out of the box.
However, HMR for Next.js app works fine and can be used with `next dev` inside Next.js project.

## Sigma, sistema de gestión académico
Quizás sabréis que soy profe en la universidad, la ESEI (Escuela Superior de Ingeniería Informática). Este curso académico, como todos los profesores de la UVigo (Universidad de Vigo), he *padecido* la implantación del sistema de gestión académico SIGMA, para gestión de actas. Según parece, este sistema en principio iba a ser utilizado por las tres universidades gallegas, pero en definitiva Santiago lo ha rechazado, Coruña solo lo emplea para postgrados... es decir, solo la UVigo lo ha adoptado para todos los procesos de actas.
### Implantando un nuevo sistema software
¿Qué problema tiene? El software, al menos tal y como se ha implantado en la UVigo es muy deficiente: tanto por resultar contraintuitivo, como por presentar directamente errores de diseño. Pero para ser justos, no toda la culpa es del programa en sí: un sistema como este debería haber sido implantado para un sector académico reducido, tras haber realizado una serie de cursos de habilitación, al menos uno para PAS y otro para PDI. Y por supuesto, esto no se hizo. Si retrocedemos un poco más, podríamos incluso decir que la implantación de un programa como este se hace para automatizar procesos, es decir, para hacer la vida de la gente más sencilla. Si comparamos lo que ofrecía **XesCampus** con lo que ofrece **Sigma**... bueno, incluso un estudio muy superficial inclinaría la balanza por continuar con **XesCampus**, en lugar de optar por una herramienta que hace que todos los pasos necesarios para la gestión de actas sean innecesariamente mucho más elaborados.
### SIstema de Gestión Académica
Lo primero, todo lo que se nos dijo sobre SIGMA es que era un sistema para introducir las actas, como XesCampus. Es decir, simplemente se trataba de cambiar un programa por otro, o eso asumimos ante la falta de documentación y de información. No es así: es un sistema que incluye a su vez dos subsistemas: el primero sería un sistema de gestión de notas (como Moovi, pero mucho más primitivo), y un sistema de gestión de actas. Así, toman sentido muchas opciones que podemos ver si "deambulamos" por la aplicación. "Transferir notas a las actas" toma sentido si asumimos que primero debemos introducir las notas, y después crear el acta a partir de ellas. Así que, no: transferir notas a las actas no implica transferirlas desde Moovi. ¿Estaría bien, eh? Pero no, eso lo haría demasiado fácil.
Hablando sobre esto, existe una opción en Moovi que resulta tan prometedora como finalmente frustrante, pues no funciona: exportar a Sigma. Hace que te ilusiones con varias pantallas para finalmente fallar con un mensaje de error. De nuevo, sería demasiado sencillo. La única alternativa es bajarse manualmente un archivo excel de Moovi de la misma sección (Moovi >> exportar e importar en Sigma >> Calificaciones >> Cargar calificaciones desde excel), solo con los campos NIA, DNI, NOMBRE, y NOTA, separados por tabuladores. Por cierto, la opción "estudiantes suspendidos" aparece marcada, porque no se refiere a los suspensos, sino a los que han suspendido su matrícula.
La pantalla inicial de **SIGMA** es bastante contraintuitiva: pulsar en las distintas filas que se corresponden con nuestras asignaturas no consigue nada: la única forma de seleccionar una asignatura/grupo es pulsar encima del icono del puntero del ratón (?). ¿Por qué hay varios grupos para una misma asingatura? Lo desconozco. En **XesCampus**, podían aparecer distintas actas si tenías alumnos Erasmus, por ejemplo. Puestos a sospechar, me da la impresión de que tiene que ver con las convocatorias que ha realizado el alumno anteriormente. Y es que nos podemos encontrar con convocatorias como "Enero", "Septiembre", "Junio" y... las anteriores más el apellido "2ª edición". Julio no existe, para añadir más confusión al conjunto.
En cualquier caso, aunque seleccionemos correctamente el grupo/asignatura, ¿qué debería pasar entonces? Aparentemente, no sucede nada, aparte de que aparecen los alumnos de ese grupo... pero sin una casilla donde introducir las notas del acta.
Mención aparte merece el icono "[+]", que nos indica que podemos desplegar varios subgrupos: normalmente, teoría y prácticas. Esto de nuevo tiene que ver con que SIGMA es también una gestión de calificaciones. Esto, en realidad, no añade más que confusión al conjunto, pues tener marcado alguno de estos subgrupos hace que no funcione ninguna de las funcionalidades que se nos ofrecen a la izquierda (?). Supongo que en el futuro no se crearán estos subgrupos; en cualquier caso, solo resta ignorarlos, pues no ofrecen ninguna ventaja o información adicional en este momento.
La forma de trabajar con **SIGMA** es la siguiente: la secuencia debe ser "seleccionar asignatura/grupo" a la izquierda, seleccionar a la derecha el grupo de la asignatura con los alumnos que vamos a calificar (siempre el grupo principal, nunca (?) el subgrupo desplegado), y entonces desplegar a la izquierda "Calificaciones" y seleccionar "Calificar finales" (para introducir las notas manualmente en el listado de estudiantes a la derecha), o "Cargar calificaciones desde excel" para obtener las calificaciones en **SIGMA** todas de una vez.
Una vez introducidas las calificaciones en **SIGMA**, debemos realizar propiamente el completado de las actas. Desde la izquierda, seleccionamos "Actas de examen" y aparece una especie de guía paso a paso. Seleccionamos entonces la convocatoria a la derecha, introduciendo la fecha de revisión del examen. No siempre la finalización de un paso nos lleva directamente al siguiente, debiendo hacerlo en estas situaciones manualmente (?). Finalmente, seleccionamos después "Traspasar notas al acta". Se nos preguntará si estamos seguros (confiamos en que así es, pues no se nos muestran las notas (?) en este momento para verificarlo), y entonces nos vamos a la derecha a "Cerrar el acta".
Por cierto, para poder listar las notas de alumnos, es necesario "seleccionar asignatura/grupo" a la izquierda, escoger el grupo a la derecha, desplegar "Calificaciones" a la izquierda, y seleccionar "Listado de calificaciones". Tras seleccionar los campos que queremos incluir en el listado, se nos presentará una pantalla que nos preguntará si queremos ver el listado o descargarlo (?). Es mejor verlo en pantalla (desde donde el mismo navegador nos ofrecerá descargarlo), porque si solo lo queremos descargar, tendremos que irnos a "mi cuenta" en la parte superior y escoger "listados", donde aparecen todos los que hemos hecho. Además, deberemos haber escogido previamente si queremos que el proceso de crear el listado sea interactivo o diferido (?). Esto tiene sentido si se va a manejar un alto volumen de datos, es decir, en este caso, de alumnos y calificaciones. Pero dado que solo vamos a poder escoger un grupo/asignatura para cada funcionalidad, y que ninguna asignatura contiene cientos de miles de alumnos, no hace sino añadir complejidad, confusión, y, en definitiva, un paso más a un proceso tan sencillo como listar calificaciones, que debería ser inmediato.
Hasta ahora he ido marcando con interrogaciones aquellas decisiones de diseño que me parecen erróneas o que al menos son cuestionables (tanto como la elección de categorías para las distintas funcionalidades del menú a la izquierda), pero lo peor viene tras cerrar el acta: una ventana emergente nos indicará que debemos abandonar la aplicación y cerrar la ventana en la que estamos. No, esto no es normal. De hecho, es inaceptable. Ningún alumno de informática va a presentar un proyecto, bien sea una solución basada en la web o en el escritorio, en el que su aplicación debe ser cerrada y volver a ser abierta para actualizar su contenido o para evitar posibles errores. Dado que este sistema software es comercial, pasamos de inaceptable a incomprensible e increíble.
### Conclusiones
Si un sistema de gestión se implanta para mejorar un proceso (gestión de notas), automatizándolo, es decir, eliminando pasos innecesarios y "mecanizar" aquellas tareas pesadas y repetitivas, **SIGMA** no es una alternativa mejor a **XesCampus**. Aún al margen de la nula formación que se ha ofrecido para manejar este sistema, además de la nula documentación disponible (un manual creado por un PAS, desconozco si a petición del rectorado o por iniciativa propia), **SIGMA** es una aplicación que obliga al usuario a realizar pasos innecesarios, sus funcionalidades ofrecen confusión en cuanto a mostrar e introducir información, y contiene errores de diseño imaceptables para una aplicación de esta envergadura.

1,919,827 | RabbitMQ: Open Source Message Broker Service | RabbitMQ is an Open Source message broker service aiding systems with microservice architecture. For... | 0 | 2024-07-12T14:46:19 | https://dev.to/ajaykrupalk/rabbitmq-open-source-message-broker-service-14f8 | webdev, javascript, tutorial, learning | RabbitMQ is an Open Source message broker service aiding systems with microservice architecture. For example, let's say you want to upload a video to YouTube, behind the scenes, there might be one service to upload the video, one to notify people who are subscribed to the author, and so on. The upload service appends “New video” events to a RabbitMQ stream. Multiple backend applications can subscribe to that stream and read new events independently of each other.
With the same example of a video streaming service, the producer is when the video is uploaded to the platform which can happen through an API. The API then produces a message with the required data which publishes it to an exchange. The exchange then routes it to one or more queues which are linked to the exchange with a routing and binding key. The message then waits in the queue until it is consumed by the consumer which in this case is the uploads service.
The Exchange can behave in one of these three ways:
- Sending the message directly to a specific queue or
- Multiple queues with a shared pattern using topics or
- To all the available queues
A basic example of sending a message to RabbitMQ locally. The below code is to send a message to the queue. Pre-requisites for this is to install [RabbitMQ](https://www.rabbitmq.com/docs/download) server and [amqplib](https://www.npmjs.com/package/amqplib) locally.
```js
//library that implements messaging protocol
import { connect} from 'amqplib'
// connect to rabbitmq locally
const connection = await connect('amqp://localhost');
const channel = await connection.createChannel();
const queue = 'test';
const message = 'hello world'
// queue can be durable either stored in RAM or memory
await channel.assertQueue(queue, {durable: false});
// message is produced
channel.sendToQueue(queue, Buffer.from(message));
```
Now that the message is sent to the queue, we need another file to receive the message, which can also be a server subscribed to the same queue and RabbitMQ client.
```js
//library that implements messaging protocol
import { connect} from 'amqplib'
// connect to rabbitmq
const connection = await connect('amqp://localhost');
const channel = await connection.createChannel();
const queue = 'test';
await channel.assertQueue(queue, {durable: false});
//consume the message
channel.consume(queue, (message) => {
const msg = {...message}
console.log("Received message: " + msg.content)
})
```
When both files are run simultaneously, the message should be received in the terminal of the second file as "hello world".
Alternatively, you can use CloudAMQP to create a RabbitMQ instance on the cloud and replace the localhost connection string with the one on the cloud. If you need a more detailed RabbitMQ blog do let me know in the comments.

1,919,828 | Pros and Cons of Using Terraform with FluxCD for GitOps | I have been working on a personal project named Smart-cash to improve some skills and learn new... | 0 | 2024-07-11T21:32:30 | https://dev.to/aws-builders/pros-and-cons-of-using-terraform-with-fluxcd-for-gitops-4k9h | kubernetes, gitops, terraform, fluxcd | I have been working on a personal project named [Smart-cash](https://github.com/danielrive/smart-cash) to improve some skills and learn new ones.
In this article, I will share my thoughts about using Terraform in the GitOps process, specifically to create the manifest and push it to the Git repo.
## The basics
GitOps relies on a Git repository as the single source of truth. New commits imply infrastructure and application updates.
Imagine a Git repository where you push all the manifests of the Kubernetes resources you want to create in your cluster. These are pulled by a tool or script that runs a "kubectl apply", creates the resources, and checks the Git repo for new changes to apply. This, at a high level, is GitOps.
## Setting up the scenario
For this case, the K8 cluster will run in AWS EKS, and Terraform is being used as an IaC tool.
A basic cluster can be created using Terraform. You can check an example [here](https://github.com/danielrive/smart-cash/blob/main/infra/terraform/modules/eks/main.tf).
FluxCD installation can be done using [the official documentation](https://fluxcd.io/flux/installation/bootstrap/github/) or you can check [this](https://dev.to/aws-builders/smartcash-project-gitops-with-fluxcd-3aep).
I will not explain some Flux concepts like sources and Kustomizations; you can check that in the links shared previously.
## Creating the YAML files
Let's say that we want to create a namespace for the development environment, we can use the following YAML:
```YAML
apiVersion: v1
kind: Namespace
metadata:
name: develop
labels:
test: true
```
We can push this file to GitHub and wait for FluxCD to do the magic.
Now let's say that we want to create a service account and associate it with an AWS IAM role, the YAML can be:
```YAML
apiVersion: v1
kind: ServiceAccount
metadata:
name: sa-test-develop
annotations:
eks.amazonaws.com/role-arn: arn:aws:iam::12345678910:role/TEST
```
This looks easy but what happens if we have multiple environments or if We don't yet know the ARN of the role because this is part of our IaC?
Here is where Terraform gives us a hand.
You can create something like a template for the manifest and some variables that you can specify with Terraform. The two manifests would look like:
```YAML
apiVersion: v1
kind: Namespace
metadata:
name: ${ENVIRONMENT}
labels:
test: true
```
```YAML
apiVersion: v1
kind: ServiceAccount
metadata:
name: sa-test-${ENVIRONMENT}
annotations:
eks.amazonaws.com/role-arn: ${ROLE_ARN}
```
Notice the ${ENVIRONMENT} and ${ROLE_ARN} variables added.
We can use the [Terraform GitHub provider](https://registry.terraform.io/providers/integrations/github/latest/docs) to push the file to the repository. Let's check the following code to push the service account:
``` terraform
resource "github_repository_file" "sa-test" {
repository = data.github_repository.flux-gitops.name
branch = main
file = "./manifest/sa-manifest.yaml"
content = templatefile(
"sa-manifest.yaml",
{
ENVIRONMENT = var.environment
ROLE_ARN = aws_iam_role.arn
}
)
commit_message = "Terraform"
commit_author = "terraform"
commit_email = "example@example"
overwrite_on_create = true
}
```
The arguments **repository** and **branch** allow us to specify the remote repo and the branch where we want to push the file. The **file** argument is the location **in the remote repository** where we want to put the file.
The **content** argument is where we pass the values to the variables created in the template, in this case ENVIRONMENT and ROLE_ARN, the values are a terraform variable and the reference to a Terraform resource that creates the role.
**overwrite_on_create** argument is needed because if you run Terraform again, it will show an error because the file already exists in the repo.
## Pros
1. Pushing the manifests using Terraform avoids the manual tasks of committing and pushing them, allowing us to automate more steps.
2. We can integrate this process into our pipeline, so a full environment can be ready when the pipeline finishes.
3. Terraform count can be used when there are many manifests to push, avoiding repetitive code.
## Cons
1. The GitHub provider has limitations. It only allows the creation of files in the remote repo but not deletion. This means that when you run Terraform destroy, the files are not deleted; they will remain in the repo.
2. If you remove the manifest from the Terraform code, it will not be deleted in the GitOps repo. This is quite dangerous because if you forget to delete it manually, your cluster will still have the resources created since FluxCD will try to sync them.
3. Terraform always generates a new commit regardless of whether a new change has been made in the file. For instance, if you update a file that is not related to the manifest, Terraform will generate a commit per file in the GitOps repo. You can have 1000 commits in one week or more, depending on how often you push changes. | danielrive |

1,915,701 | 10 Cool JavaScript Tricks and Tips | Introduction JavaScript is a versatile programming language widely used for web... | 0 | 2024-07-08T11:57:03 | https://dev.to/koolkamalkishor/10-cool-javascript-tricks-and-tips-1g40 | ### Introduction
JavaScript is a versatile programming language widely used for web development. Understanding its key features and best practices can significantly enhance your coding efficiency and quality.
### Tips
1. **Use of Arrow Functions**
Arrow functions provide a concise syntax for defining functions. They also lexically bind `this`, avoiding the need for `bind()` or `that = this` tricks.
**Example:**
```javascript
// Traditional function
function multiply(a, b) {
return a * b;
}
// Arrow function
const multiply = (a, b) => a * b;
```
2.**Destructuring Assignment**
Destructuring allows you to extract values from arrays or objects into distinct variables, making code more readable.
**Example:**
```javascript
// Destructuring arrays
const [first, second] = ['apple', 'banana'];
// Destructuring objects
const { name, age } = { name: 'Alice', age: 30 };
```
3. **Template Literals**
Template literals provide a cleaner way to concatenate strings and embed expressions using `${}`.
**Example:**
```javascript
const name = 'Alice';
const greeting = `Hello, ${name}!`;
console.log(greeting); // Output: Hello, Alice!
```
4. **Async/Await for Asynchronous Operations**
Async functions combined with `await` provide a synchronous-like way to write asynchronous code, enhancing readability.
**Example:**
```javascript
async function fetchData() {
try {
let response = await fetch('https://api.example.com/data');
let data = await response.json();
return data;
} catch (error) {
console.error('Error fetching data:', error);
}
}
```
5. **Map, Filter, and Reduce**
These array methods are powerful tools for manipulating data in arrays, providing concise and functional programming capabilities.
**Example:**
```javascript
const numbers = [1, 2, 3, 4, 5];
// Map example
const doubled = numbers.map(num => num * 2);
// Filter example
const evenNumbers = numbers.filter(num => num % 2 === 0);
// Reduce example
const sum = numbers.reduce((acc, curr) => acc + curr, 0);
```
6. **Promises**
Promises are a clean way to handle asynchronous operations and simplify callback hell by chaining multiple async actions.
**Example:**
```javascript
function fetchData() {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve('Data fetched successfully');
}, 2000);
});
}
fetchData().then(result => {
console.log(result); // Output: Data fetched successfully
}).catch(error => {
console.error('Error fetching data:', error);
});
```
7. **Spread and Rest Operators**
Spread and rest operators (`...`) simplify working with arrays and function arguments, respectively.
**Example:**
```javascript
// Spread operator example
const array1 = [1, 2, 3];
const array2 = [...array1, 4, 5];
// Rest parameter example
function sum(...args) {
return args.reduce((acc, curr) => acc + curr, 0);
}
sum(1, 2, 3); // Output: 6
```
8. **Object and Array Methods**
JavaScript provides handy methods for working with objects and arrays, enhancing productivity.
**Example:**
```javascript
const user = {
name: 'Alice',
age: 30,
email: 'alice@example.com'
};
// Object.keys()
const keys = Object.keys(user); // ['name', 'age', 'email']
// Array.includes()
const numbers = [1, 2, 3, 4, 5];
const includesThree = numbers.includes(3); // true
```
9. **LocalStorage and SessionStorage**
`localStorage` and `sessionStorage` provide easy-to-use mechanisms for storing key-value pairs locally in the browser.
**Example:**
```javascript
// Saving data
localStorage.setItem('username', 'Alice');
// Retrieving data
const username = localStorage.getItem('username');
// Removing data
localStorage.removeItem('username');
```
10. **Error Handling**
Proper error handling is crucial for debugging and maintaining JavaScript applications, improving reliability.
**Example:**
```javascript
try {
// Code that may throw an error
throw new Error('Something went wrong');
} catch (error) {
console.error('Error:', error.message);
}
```
### Conclusion
Mastering these JavaScript tips can streamline your development process and improve code quality. Experiment with these techniques in your projects to leverage the full power of JavaScript.
### Additional Tips (Optional)
- **ES6+ Features**: Explore more features like `let` and `const`, classes, and modules to further enhance your JavaScript skills.
- **Browser APIs**: Utilize browser APIs such as `fetch()` for HTTP requests or `IntersectionObserver` for lazy loading to enrich your web applications.
By following these examples and explanations, you can create a compelling and educational blog post on "10 Cool Tips in JavaScript" that resonates with developers of all skill levels. | koolkamalkishor | |
1,919,830 | Top 5 Use Cases of Immersive Technology in Education in Canada | Immersive technology, encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality... | 0 | 2024-07-11T14:17:11 | https://dev.to/priyanka_aich/top-5-use-cases-of-immersive-technology-in-education-in-canada-1882 | webdev, devops, ai | Immersive technology, encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), is revolutionizing the educational landscape by providing interactive and engaging learning experiences. This technology transports students beyond traditional classrooms, allowing them to explore complex concepts and environments in a more tangible and impactful way. The importance of immersive technology in education cannot be overstated, as it enhances understanding, retention, and student engagement.
Canada stands at the forefront of integrating immersive technology into education, showcasing a commitment to innovation and progressive teaching methods. In 2022, a study by the Canadian EdTech Alliance reported that 68% of educational institutions in Canada had adopted some form of immersive technology, reflecting a significant increase from 45% in 2020. This rapid adoption is not only enriching the learning experience but also generating substantial profits. For instance, institutions utilizing immersive technology saw a 25% increase in student enrollment rates and a 20% rise in international student applications between 2021 and 2023, according to a report by EduCanada.
In this blog, we will explore the top five use cases of immersive technology in education in Canada, highlighting how these innovations are shaping the future of learning and setting new standards globally.
**1. Immersive Field Trips**
Immersive field trips are revolutionizing the educational experience in Canada by utilizing Virtual Reality (VR) and Augmented Reality (AR) to transport students to distant locations and historical periods that were previously inaccessible. This innovative approach enhances student engagement and improves educational outcomes.
One notable example is the program initiated by the Toronto District School Board (TDSB) in 2021. TDSB partnered with various tech companies to introduce VR headsets and AR applications into the curriculum. The program aimed to enhance the geography and history curricula, provide equitable learning experiences regardless of socioeconomic status, and foster engagement and curiosity in students.
The implementation involved careful selection of content, where TDSB collaborated with content creators to develop and curate VR and AR experiences aligned with the curriculum. These included virtual tours of Canadian historical sites, geographic explorations, and science-related adventures. Teachers underwent comprehensive training to effectively use VR and AR tools in their lessons, including workshops, instructional manuals, and ongoing support. VR headsets and AR-enabled tablets were distributed across schools, with mobile VR kits available for students without access to personal devices.
The immersive field trip program yielded impressive results. According to a 2022 survey, 85% of students reported higher engagement levels during VR-enhanced lessons compared to traditional methods. Post-implementation assessments indicated a 30% increase in knowledge retention among students who participated in immersive field trips. The program ensured that all students, regardless of financial background, could experience high-quality educational trips.
**2. Medical Training and Surgical Simulations**
Medical training and surgical simulations have entered a new era with the advent of Virtual Reality (VR) technology. This innovative approach allows surgeons and medical students to practice complex procedures in a virtual, risk-free environment, revolutionizing the way surgical skills are acquired and honed.
The University of Toronto’s Faculty of Medicine has spearheaded the integration of VR simulations into surgical training. Surgeons and medical students now use VR to simulate intricate surgical procedures, providing them with a platform for repeated practice and skill refinement. This immersive experience closely mimics real-world scenarios, offering a safe space to make mistakes, learn from them, and master techniques under various conditions.
**Impact**
The implementation of VR simulations at the University of Toronto has demonstrated significant benefits:
**- Improved Surgical Skills:** Surgeons can practice and refine their techniques without the pressure of performing on live patients, leading to enhanced proficiency in handling complex surgeries.
**- Reduced Errors:** By allowing for repeated practice, VR simulations help reduce errors during actual surgical procedures, thereby improving patient outcomes and safety.
**- Enhanced Patient Safety:** The ability to simulate surgeries in a controlled virtual environment contributes to better-prepared surgeons, ultimately enhancing overall patient safety and care quality.
According to a 2023 study conducted at the University of Toronto, surgeons who underwent VR-based training showed a 35% improvement in procedural accuracy compared to those trained using traditional methods. Additionally, the study reported a 25% reduction in surgical errors attributed to the use of VR simulations.
This approach showcases the efficacy of immersive technology in medical education, surpassing the limitations of traditional learning environments. It not only prepares medical professionals more effectively but also sets new standards for surgical training by leveraging cutting-edge VR technology.
**3. Metaverse Campus**
The Virtual University of British Columbia Campus project represents a pioneering initiative in higher education, leveraging Metaverse technology to create a virtual counterpart to the physical campus environment. This innovative project aims to enhance accessibility, engagement, and inclusivity for students worldwide.
**Impact**
The Virtual UBC Campus has had a profound impact on the university community:
**- Global Reach:** The virtual campus has attracted over 10,000 unique visitors monthly from across the globe, allowing students to experience UBC’s vibrant community and campus life remotely.
**- Enhanced Accessibility:** 85% of surveyed students reported feeling more connected to campus activities and events since the launch of the virtual campus.

1,919,863 | What's Next For SWE Students? | What's up SE Nerd!! I'm back with another post. This one won't be as technical as I will be using... | 0 | 2024-07-11T14:21:27 | https://dev.to/trippl/whats-next-for-swe-students-26ak | softwareengineering, software | What's up SE Nerd!! I'm back with another post. This one won't be as technical as I will be using this one to reflect on my last 15 weeks of a SWE Bootcamp!
First of all, I want everyone reading this to know that I didn't know much about computers or much about technology before I started this program. I was halfway through a SWE degree and decided I was ready to jump into it, crunch as much learning as I can and start getting some experience in this field.
When I first started this course, I didn't know what to expect. After taking the prerequisites to get into this course, I knew it was going to be a challenge, but I also knew that if I put as much time and effort into it I would get results. That's how I approached this from the beginning and I never strayed away from that. I put everything I have into this course. There were times were I would stay up until 3 am debugging or just knowing I had a lot to do to soak up this information in a short amount of time.
As I continued, the extra time and effort was all I needed to not just succeed, but to push limits of my new skills and knowledge. I would shoot past the moon for any project, I would continue doing labs or challenges to see other ways of doing things and getting better results.
This course has sparked a fire in me. This is what I was built for. I love it and I never want to get off the computer now!!
I want to share what makes this field special for me. I have never been an artistic person, and it's unfortunate because I have a very creative mind. I have never had a job or been involved with anything that I can actually put my creative thoughts into action. This is it, this is my art, this is my comfort zone, this is IT!! I absolutely love putting in so much effort to see amazing results.
I hope my blogs have been a good guide to starting your SWE journey, I will continue to blog about the job process and where this education takes me from here. Good luck to all of you, and it's always good to be a SE Nerd!! | trippl |
1,919,869 | Unlocking the Full Potential of GitGuardian: Empowering Developers In Code Security | At GitGuardian, we are convinced that effective security requires a shared responsibility model.... | 0 | 2024-07-11T14:34:24 | https://blog.gitguardian.com/empowering-developers-in-code-security/ | security, cybersecurity, git, cli | At GitGuardian, we are convinced that effective security requires a shared responsibility model. Developers are already overburdened with their primary tasks of writing code and delivering features, and we think it is not realistic to expect them to know everything about security, be responsible for triaging and handling incidents on their own, or consider all the implications of security.
Adding security responsibilities without proper support and integration can lead to frustration, resistance, and, ultimately, a less secure environment. Yet, their involvement in fixing code security issues is crucial and cannot be replaced by security work.
We've seen "shifting left" being misinterpreted as simply handing developers security tools and more responsibility, yet we assume adding more tools has never been a solution to security.
Our platform is built around the idea of creating a collaborative environment where security is seamlessly integrated into the development process. That's why we provide tools and processes that empower developers to write secure code without adding unnecessary toil.
In this blog, we will highlight how GitGuardian is much more than just another security scanner. It is a true end-to-end platform supporting a partnership between dev and sec.
1\. Empower Developers with ggshield
------------------------------------
Developers love to be in control of their tooling, so it's essential to provide them with flexible security tools they can integrate into their local workflow. GitGuardian's CLI, [ggshield](https://github.com/GitGuardian/ggshield?ref=blog.gitguardian.com), provides just that: a scanner for the command line that can be used manually or as a pre-commit (or pre-push) hook to ensure every commit is secrets-free.
> [How To Use ggshield To Avoid Hardcoded Secrets - cheat sheet included(https://blog.gitguardian.com/how-to-use-ggshield-to-avoid-hardcoded-secrets-cheat-sheet-included/)
GitGuardian's ggshield CLI tool can help you keep your secrets away from your repos and pipelines. Download our handy cheat sheet to quickly become proficient in our CLI tool.
More importantly, the tool is always in sync with the developer's GitGuardian account, meaning that any secret ignored on the dashboard won't trigger an unnecessary alert.
With ggshield, developers are enabled to prevent many mistakes. Yet, if they decide to work around not adopting ggshield, GitGuardian will still scan code when it is pushed to a shared repository or during the Continuous Integration process, stopping vulnerabilities from falling through the cracks. GGshield covers three main use cases:
- Secrets Scanning: Ensuring that any plaintext credentials added to the code are discovered before they leave the machine.
- Source Composition Analysis: Scanning for vulnerabilities in new code changes, blocking when a new component or change introduces a new vulnerability.
- Infrastructure as Code Scanning: Checking for misconfigurations in IaC tools like Terraform before committing code to the pipeline.
Further, each of these hooks has many options for further configuration, such as ignoring specific paths or only blocking Critical or High-risk CVEs in the case of SCA. Hooks can be set at a global level in Git, meaning that once installed every new Git commit will get the same level of automatic testing no matter which project the developer is focused on.
The number of overall incidents will decrease as developers adopt these guardrails and develop better security habits. This approach serves the developers by ensuring their code reaches production more often and keeps the organization safer.
2\. Ensure Consistent Findings and Create a Common Language
-----------------------------------------------------------
Nothing kills collaboration faster than a crippling lack of understanding and an endless barrage of back-and-forth communication. How to avoid that? By ensuring all parties talk about the same thing, with all the relevant context.
GitGuardian gathers all findings around a secret sprawl or dependency vulnerability event into a logical unit: the "[incident](https://docs.gitguardian.com/secrets-detection/remediate/overview?ref=blog.gitguardian.com)." Rather than just displaying alerts in email or exporting them to a CSV or text file, the GitGuardian Platform tracks all occurrences of the same secret under the same incident in the workspace. This approach also gives developers and security teams a common language to discuss any security issues, as each incident has a unique identifier and a clear timeline to track remediation progress.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXdlL90b749RdJ1UdTkZlGiAwOWV_zQgWNnz6va_KLnd9TFJtqWGEsST-Lnp_AOubwbPTHWfvi-LvqyiLOtb7mCWzzjN8N90DW6LAXMu1qx1MBFbZHbP3yQRfkEPLKwtNTAXNW56EoOMVESzklWKMKB5ig?key=YNg4rHjYZJmUrsbYFOJyGg)
GitGuardian Incident view
From one platform, teams can organize alerts, efficiently gather feedback from the developer at the right moment, and better coordinate the needed response. They can also introduce guardrails to the development teams, optionally blocking any problems before they can become full-blown incidents. We are here to help you throughout your security journey.
3\. Partner with Developers in Incident Remediation
---------------------------------------------------
Gathering feedback from the developer involved is one critical juncture when remediating an incident. GitGuardian streamlines this process and gives the flexibility you need to share access to the incident. Whether you need to provide full or partial access, share incidents selectively, or seamlessly integrate with JIRA, GitGuardian empowers you to choose what works best for your team.
### Option 1: Full Access
Some teams prefer to give the developers full access to the platform to see any incident the security team does. In this case, the developer can simply be invited to see the incident view directly from the [GitGuardian incident dashboard](https://docs.gitguardian.com/platform/core-concepts/collaboration-between-appsecs-and-devs?ref=blog.gitguardian.com).
### Option 2: Partial Access
Some teams only want to invite developers to work within the dashboard for certain incidents related to specific repositories. [GitGuardian's Teams feature](https://docs.gitguardian.com/platform/collaboration-and-sharing/teams?ref=blog.gitguardian.com) allows you to restrict access to incidents to specific team members, giving them automatic access without the worry of unrestricted access.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXe0Z9B1tcw_WuIG1CoYeT95bK5wiTSPYZsD46aHF385QFL05VRUcZXTSR5RT0J5_TH9WpVhFM9ZoSXi7TsUxT2n7RxgEaPFCqM4y1jQcuB5TTXHl6YrvGiLE7ikqWjquNwx_AYR99gCIvgkoGa9Ye03?key=YNg4rHjYZJmUrsbYFOJyGg)
Caption: The share incident menu in the GitGuardian dashboard.
### Option 3: Selective Sharing
Sometimes, the best choice is not to onboard developers to the GitGuardian workspace. For teams supervising a larger fleet of repositories, it just doesn't make sense to overwhelm developers with irrelevant alerts in their inboxes or Slack channels.
If that's the preferred solution, GitGuardian makes sharing an incident extremely efficient through our public sharing functionality.
Security team members can generate a public link that is accessible to unregistered users and provides all the details of the incident along with a feedback form. The form asks the developer who made the commit if this is an actual secret, if the secret gives access to any sensitive information or services, and if the secret has been revoked. It also gives them a text box to provide any additional relevant information. When the link is no longer needed, it can easily be revoked.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXf9L0J3BPE_H5TRDD4xgc5OxKK4J8dQIbIRpn7_tzt42EoFTNNrpgAyrTe_lBSsvnlKvLasXw9vekr8R5HB8dipqCCxR8KXVkGb-2dbOh_TlPsfL3FvrXrme-tDa7wj4-gjRpA8-AmP6h6z4zHNLrIIA0w?key=YNg4rHjYZJmUrsbYFOJyGg)
The "share publicly" interface inside the incident view in GitGuardian.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXffs5583VcFVOOKqrGaabGkBfZqzSYyK67hKQES4Vc1ZT7KqySYIabfiXKuutyY9b-4cW3v6ihAWMX34iZYmQfTlzic26gavEh65EiAmjxX8NKRgr47zgD4dnfiBo9jp7XspTwKttXT_cI6Mo9we5PbgtI?key=YNg4rHjYZJmUrsbYFOJyGg)
The "submit your feedback" form from the shared link.
If the commit author is trusted to close the incident themselves, then with one additional option selected from the dashboard, this same feedback form can add an additional field that will allow the developer to resolve or ignore the incident themselves.
[](https://lh7-us.googleusercontent.com/docsz/AD_4nXdXRBGgUmBiUtfWVxqAE4NhP82mmG9NbqvSdaoCzLFNRaf4cb0Q8Ufz6ElBgD0L0BXjJBkTHYCzjiy6jWq6GlMPmAKyIW8LoNpXgbQTEjxbM38-Lju4xHOoW9UE1vaPxkuzo7WpGROATWK_lBlcK1kQug?key=YNg4rHjYZJmUrsbYFOJyGg)
Resolve or ignore the incident area from the shared link.
### Option 4: JIRA
If you are working in an Atlassian JIRA-driven environment, it makes sense to keep everything together in one single place: GitGuardian can integrate transparently there through the [GitGuardian Advanced Jira Cloud integration](https://www.youtube.com/watch?v=wjqiM3fnoU0&ref=blog.gitguardian.com). GitGuardian can be configured to create a new Jira ticket using custom templates to communicate consistently with developers about needed remediation efforts.
Any further updates from the GitGuardian incident will get pushed as comments to each related Jira issue, and conversely, it's possible to configure the Jira tickets to resolve an incident in GitGuardian when a specific status is reached. It will mark the associated incident as Resolved so you can stay focused on other work.
This can help developers stay in a workflow they are very used to while working on remediating incidents.
4\. Progressive Implementation of Guardrails for Better Code Security
---------------------------------------------------------------------
When your team is ready to add security earlier in the development process, we suggest introducing 'guardrails' into their workflow. Guardrails, unlike wholly new processes, can slide into place unobtrusively, providing warnings about potential security issues only when they are actionable and true positives. Ideally, you want to minimize friction and enable developers to deliver safer, better code that will pass tests down the line.
One tool that is almost universal across development and DevOps teams is Git. With over 97% of developers using Git daily, it is a familiar platform that can be leveraged to enhance security. Built directly into Git is an automation platform called Git Hooks, which can trigger just-in-time scanning at specific stages of the Git workflow, such as right before a commit is made.
By catching issues before making a commit and providing direct feedback on how to fix them, developers can address security concerns with minimal disruption. This approach is much less expensive and time-consuming than addressing issues later in the development process. This can actually increase the time spent on new code by reducing the amount of maintenance that eventually needs done.
Conclusion: More Security, Less Toil
------------------------------------
Empowering developers in code security is crucial for minimizing vulnerabilities and ensuring the safety of the organization. By meeting developers where they are, providing seamless integration of security tools, and fostering a collaborative approach, security teams such as GitGuardian can unlock the full potential of their security tools.
GitGuardian's ggshield and its seamless integration with developer workflows via Git Hooks offer a practical solution to the challenges of secrets security. By adopting appropriate and accurate guardrails, developers can continue to focus on building features and functionality while ensuring their code is secure.
Working together, security teams and developers can create a safer, more efficient development environment that benefits the entire organization. By embracing this collaborative approach, we can address the complexities of modern security challenges and achieve greater success in delivering secure code. | dwayne_mcdaniel |

Dr. Badie Idris and our team are dedicated to providing advanced solutions for hair loss, including the innovative Regenera Stem Cell Hair Treatment. With locations in DHA Lahore and Kohinoor City Faisalabad Visit now, we are conveniently accessible to serve clients throughout Punjab, Pakistan.
Understanding Hair Loss
Going bald is a typical worry that influences a huge number of individuals around the world, all kinds of people. It can result from different variables, including hereditary qualities, hormonal changes, ailments, and way of life decisions. At London Aesthetics and Rejuvenation Center, we understand the profound impact that hair loss can have on your confidence and quality of life. Our goal is to offer effective treatments that address the root causes of hair loss and promote natural hair growth.
What is Regenera Stem Cell Hair Treatment?
Regenera Activa is a cutting-edge treatment that leverages the body's natural regenerative capabilities to combat hair loss. This minimally invasive procedure uses autologous micrografts, which are tiny grafts derived from the patient's own scalp. These micrografts contain potent stem cells and growth factors that stimulate hair follicles, encouraging hair regrowth and improving hair density.
The Science Behind Regenera
Regenera Stem Cell Hair Treatment works by harnessing the power of regenerative medicine. The cycle includes the extraction of micrografts from a little region of the scalp, typically from the rear of the head where hair is more impervious to diminishing. These micrografts are then processed to isolate stem cells and growth factors, which are subsequently injected into the areas of the scalp experiencing hair loss.
The stem cells and growth factors promote the repair and regeneration of hair follicles, enhancing their ability to produce new, healthy hair. This natural approach not only targets the symptoms of hair loss but also addresses the underlying causes, providing long-lasting and effective results.
The Treatment Process
Initial Consultation
Your journey with Regenera Stem Cell Hair Treatment begins with a comprehensive consultation with Dr. Badie Idris. During this consultation, Dr. Idris will assess your hair loss condition, review your medical history, and discuss your goals and expectations. This thorough evaluation ensures that Regenera is the right treatment for you and helps to create a personalized treatment plan tailored to your needs.
Procedure Day
On the day of the procedure, you will be comfortably seated, and the treatment area will be cleaned and prepared. Local anesthesia is administered to ensure that you remain comfortable throughout the process. The procedure involves the following steps:
Extraction: A small section of the scalp, typically from the back of the head, is selected for micrograft extraction. This area is known for its dense and healthy hair follicles.
Processing: The extracted micrografts are processed using the Regenera Activa device, which isolates the stem cells and growth factors from the tissue.
Injection: The concentrated solution of stem cells and growth factors is injected into the areas of the scalp experiencing hair loss.
The whole strategy normally takes around one to two hours, contingent upon the degree of the treatment region. Since it is minimally invasive, you can expect minimal discomfort and a swift recovery.
Post-Treatment Care
After the procedure, you may experience mild redness or swelling at the injection sites, which typically subsides within a few days. Dr. Idris will provide you with detailed aftercare instructions to ensure optimal results. These instructions may include:
Avoiding strenuous activities for a few days.
Refraining from washing your hair for the first 24-48 hours.
Utilizing endorsed skin medicines to help the recuperating system.
Most patients can resume their normal activities within a day or two after the treatment.
Results and Expectations
The results of Regenera Stem Cell Hair Treatment are gradual and natural. You can expect to see initial improvements in hair density and thickness within the first few months, with optimal results typically visible after six to twelve months. The treatment's effectiveness varies from person to person, depending on factors such as the extent of hair loss and individual response to the treatment.
One of the significant advantages of Regenera is its ability to provide long-lasting results. Since the treatment stimulates the natural regenerative processes of the hair follicles, the new hair growth is sustainable and continues to improve over time.

1,919,868 | Sharing state between unrelated React components | Want to show how you can share any serializable data between React components, e.g. client components... | 0 | 2024-07-11T14:32:37 | https://dev.to/asmyshlyaev177/sharing-state-between-unrelated-react-components-4aia | nextjs, javascript, react | Want to show how you can share any serializable data between React components, e.g. client components in NextJS.
We have few unrelated components:
Let's create an object that will contain initial state
```typescript
export const state: { count: number } = { count: 0 };
```
We can store data in a `WeakMap`, `state` will be a key to access it. Also, will need a `subscribers` array.
```typescript
const stateMap = new WeakMap<object, object>();
const subscribers: (() => void)[] = [];
```
Now let's write a hook to subscribe to data changes.
```typescript
export function useCommonState<T extends object>(stateObj: T) {
// more efficient than `useEffect` since we don't have any deps
React.useInsertionEffect(() => {
const cb = () => {
const val = stateMap.get(stateObj);
_setState(val!);
};
// subscribe to events
subscribers.push(cb);
return () => {
subscribers.slice(subscribers.indexOf(cb), 1);
};
}, []);
}
```
Now let's add logic related to get and set state
```typescript
// all instances of hook will point to same object reference
const [state, _setState] = React.useState<typeof stateObj>(() => {
const val = stateMap.get(stateObj) as T;
if (!val) {
stateMap.set(stateObj, stateObj)
return stateObj
}
return val
});
const setState = React.useCallback((newVal: object) => {
// update value
stateMap.set(stateObj, newVal);
// notify all hook instances
subscribers.forEach((sub) => sub());
}, []);
return { state, setState };
```
And now can use it in 3 components like
```typescript
import { state as myState } from './state';
//...
const { state, setState } = useCommonState(myState);
<button
onClick={() => setState({ count: state.count + 1 })}
className="p-2 border"
>
+
</button>
// ...

1,919,870 | Understanding RAID Levels: A Comprehensive Guide to RAID 0, 1, 5, 6, 10, and Beyond | In today’s fast-paced digital landscape, data storage is crucial for safeguarding critical... | 0 | 2024-07-11T14:35:21 | https://dev.to/pltnvs/understanding-raid-levels-a-comprehensive-guide-to-raid-0-1-5-6-10-and-beyond-5948 | dataengineering, softwareraid, dataredundancy, datastorage | In today’s fast-paced digital landscape, data storage is crucial for safeguarding critical information. [RAID ](https://xinnor.io/what-is-xiraid/)technology has revolutionized data storage, offering improved performance, increased data redundancy, and optimized capacity. However, with various RAID levels available, selecting the ideal configuration can be challenging.
In this comprehensive article, we demystify RAID technology, guiding you through the intricacies of RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and more. By exploring their characteristics, benefits, and drawbacks, we empower you to make informed decisions that align with your specific storage demands. Whether you’re a tech enthusiast, system administrator, or business owner, this guide equips you with the expertise to fortify your data infrastructure effectively.
## RAID 0
RAID 0 encompasses a configuration wherein all drives are merged into a single logical one. This level delivers exceptional performance at a reduced cost. However, it lacks data protection mechanisms, rendering it highly susceptible to data loss in the event of a drive failure. Consequently, the adoption of RAID 0 is not recommended for mission critical data.
### Advantages:
- Offers high-speed performance and availability while maintaining a cost-effective approach.
- Utilizes the entire capacity of each individual drive.
- Configuration is straightforward and user-friendly.
### Disadvantages:
- RAID 0 lacks any form of data protection.
- In the event of a single drive failure, all data becomes irreversibly lost, with no possibility of recovery.
### Areas of application
This RAID level is advisable for implementation in non-mission-critical scenarios. RAID 0 is suitable for purposes where the primary concern is maximizing performance and data read/write speeds. It is commonly used in scenarios where data redundancy (fault tolerance) is not a critical requirement, and the main focus is on improving the system’s overall data processing capabilities.
## RAID 1
RAID 1, also known as “mirroring,” is a method in which all data is duplicated on two separate drives, with one set of data appearing as a logical drive. RAID 1 is primarily focused on providing data protection rather than improving performance or increasing storage capacity. Because data is replicated over 2 drives, the usable capacity is 50% of the total available drives in the RAID array.
### Advantages:
- High levels of redundancy — each drive is an exact copy of another.
- If one drive fails, the system continues to function normally with no data loss.
### Disadvantages:
- Usable capacity is limited to 50% due to the need to store complete duplicates of data.
- RAID 1 performance does not significantly exceed that of a single drive.
### Areas of application
This RAID level finds frequent utilization in scenarios where storage capacity and cost are not a concern, yet the imperative requirement lies in the ability to fully recover data in the event of a drive failure. It’s commonly used for booth drives, small business applications, and personal data storage, ensuring continuous access to information even if one drive fails.
## RAID 5
RAID 5, widely regarded as the most prevalent and versatile RAID level, employs a technique known as data block striping across the entirety of drives within the array (comprising 3 to N drives). It further distributes parity information evenly across all drives. In the event of a single drive failure, the system utilizes the parity information from the functioning drives to recover lost data blocks.
### Advantages:
- Strikes a favorable balance between cost and performance considerations.
- Capability to recover data in the event of a single drive failure.
- Enhanced data read performance.
- Scalability: RAID 5 facilitates effortless expansion of storage capacity by incorporating additional drives without system interruption.
### Disadvantages:
Parity storage leads to a reduction in individual drive capacity.
data loss in case 2 drives fail in the array.
### Areas of application
This RAID level enjoys widespread adoption across diverse environments, including file servers, general-purpose storage servers, backup servers, and streaming data applications, among others. It offers superior performance while maintaining an optimal price-performance ratio.
## RAID 6
RAID 6, also known as “double-parity interleaving,” is a data storage and recovery technique that distributes data across multiple drives while utilizing double-parity for enhanced fault tolerance. While RAID 6 performs similarly to RAID 5 in terms of performance and capacity, it offers an advantage by distributing the second parity scheme across different drives, allowing it to withstand the simultaneous failure of two drives within the array.
### Advantages:
- RAID 6 provides a reasonable price-quality ratio with good overall performance.
- The array can endure the simultaneous failure of two drives or the failure of one drive, followed by the subsequent failure of a second drive during data recovery.
### Disadvantages:
- RAID 6 incurs higher costs compared to RAID 5, as it sacrifices the capacity of two drives for parity data.
- In most scenarios, RAID 6 performs slightly slower than RAID 5.
### Areas of application
RAID 6 is highly recommended for applications such as file servers, shared storage servers, and backup servers. It strikes a favorable balance between cost and performance, offering reliable and versatile operation. The key advantage of RAID 6 lies in its ability to tolerate the failure of two drives simultaneously or the failure of one drive followed by a second drive during the data recovery process.
## RAID 7.3
To increase the reliability of the data warehouse, XINNOR engineers have developed and introduced to the market a new triple-parity RAID level, known as RAID 7.3. This level was designed with a unique erasure coding technology, which allows to perform checksum calculations at high speed. Thus, RAID 7.3 achieves performance comparable to RAID 6.
### Advantages:
RAID 7.3, with triple parity, is ideal for use with high-capacity drives, where the recovery process can take long time. This is especially true in conditions of intense workload, where a long rebuilding process increases the risk of subsequent drive failure and potentially threatens data security.
The use of RAID 7.3 in combination with hard drives or hybrid solutions significantly reduces storage costs by reducing the number of drives used, meeting customer requirements for reliability and performance.
In addition, RAID 7.3 provides extensive capabilities for managing the infrastructure of your data centers. It offers a convenient and reliable technology for organizing a storage array.
## RAID 10
RAID 10, also known as “striping and mirroring”, combines the benefits of RAID 1 and RAID 0 by creating multiple mirrored sets that are interleaved. RAID 10 provides high performance, good data protection, and does not require parity calculations.
RAID 10 requires at least four drives, and the usable capacity is 50% of the total drive capacity. However, it is worth noting that RAID 10 can use more than four drives, which must be a multiple of two. For example, a RAID 10 array of eight drives provides high performance on both spinning and SSD drives because data reads and writes are split into smaller chunks on each drive.
### Advantages:
- High speed and reliability through a combination of striping and mirroring.
### Disadvantages:
- Expensive configuration because it requires the use of more drives to achieve usable capacity.
- Not recommended for large capacities due to cost constraints.
- Slightly slower than RAID 5 in some streaming scenarios.
### Areas of application
This RAID level is well-suited for databases, as it offers elevated read and write performance, and for virtualization, providing servers with both high performance and reliability. It is particularly relevant in domains such as video editing and multimedia applications, where RAID 10 can efficiently manage substantial data volumes. Additionally, it is recommended for mission-critical applications due to its robust data protection and recovery capabilities in the event of drive failure. Moreover, in the context of high-traffic file servers, RAID 10 adeptly handles heavy network traffic while delivering remarkable file system responsiveness.
### RAID 50 & 60
There are also RAID 5+0 (RAID 50) and RAID 6+0 (RAID 60), which are hybrid RAID configurations that combine the features of multiple RAID levels for improved performance and fault tolerance. RAID 5+0 uses multiple RAID 5 arrays interleaved with RAID 0, providing faster data access and the ability to tolerate a single drive failure per RAID 5 array. RAID 6+0 combines multiple RAID 6 arrays interleaved with RAID 0, providing even better fault tolerance by tolerating two-drives failures per RAID 6 array. These configurations are suitable for situations requiring both high performance and enhanced data protection.
## RAID N+M
RAID level N+M is a data block allocation system using M parity distribution. This level allows the end user to independently determine the number of drives that will be used to store checksums. RAID N+M is supported by xiRAID. This is an innovative technology, thanks to which it is possible to restore information in the event of a failure of up to 32 drives (depends on how many drives are used to store checksums).
## How to Choose the RAID Level
Choosing the right RAID level depends on your specific storage needs, performance requirements, data redundancy preferences, and budget constraints. Here are the key factors to consider when making this decision:
1. **Performance Requirements**: Different RAID levels offer varying levels of performance. RAID 0, for example, provides excellent performance by striping data across multiple drives, but it lacks data redundancy. On the other hand, RAID 5 and RAID 6 offer both performance and redundancy but are not as fast as RAID 0. Consider the speed at which you need to access and transfer data, as well as the workload demands of your system.
2. **Data Redundancy and Fault Tolerance**: If data protection is a top priority, RAID levels with redundancy are essential. RAID 1 mirrors data across drives, providing a high level of fault tolerance, while RAID 5 and RAID 6 use distributed parity to protect against drive failures. RAID 10 combines mirroring and striping, offering both speed and redundancy. Assess the criticality of your data and how much protection you need against potential drive failures.
3. **Drive Utilization**: Different RAID levels use drives in various ways, impacting overall storage capacity. RAID 0 utilizes all drives for data storage, providing maximum capacity but no redundancy. In contrast, RAID 1 uses half the capacity for mirroring, reducing usable storage but ensuring complete redundancy. Evaluate how important drive utilization is for your setup.
4. **Number of Drives Available**: Some RAID levels require a minimum number of drives to function effectively. RAID 5, for instance, needs a minimum of three drives, while RAID 6 typically requires at least four drives. If you have limited drive slots or a specific number of available drives, this will influence your RAID level choice.
5. **Cost Considerations**: RAID configurations come with varying costs based on the number of drives needed and the drive types used (HDDs or SSDs). RAID 0 and RAID 5 might be more cost-effective due to their lower drive requirements, while RAID 1 and RAID 10 could be more expensive due to the need for mirroring. Balance your budget constraints with the level of performance and redundancy required.
6. **Complexity and Manageability**: Some RAID levels, like RAID 0 and RAID 1, are relatively simple to set up and manage, making them suitable for less experienced users. In contrast, RAID 5 and RAID 6 configurations involve distributed parity, which adds complexity but provides more redundancy. Consider the level of expertise and effort required for configuring and maintaining your chosen RAID level.
7. **Specific Use Cases**: Certain RAID levels excel in particular scenarios. For instance, RAID 0 is ideal for temporary data storage or high-performance applications where redundancy is not a concern. RAID 5 and RAID 6 are well-suited for data-centric environments that require both performance and fault tolerance. Identify your specific use case to align it with the RAID level that best suits your requirements.
By carefully evaluating these factors and understanding the strengths and weaknesses of each RAID level, you can confidently select the right RAID configuration that aligns with your storage needs and ensures the optimal balance between performance, data protection, and cost-effectiveness.
Several software solutions are available to optimize RAID configurations and achieve peak performance. A notable example is xiRAID, a [software RAID](https://xinnor.io/what-is-xiraid/) engine, a universal tool compatible with all RAID levels. We can help you choose the best solution for your business needs.

1,919,871 | After Effects: Favourite Expressions Part 1, Linear() and Ease() | Introduction Now I've established the basics of After Effects, and why I like to use... | 28,010 | 2024-07-11T14:59:37 | https://dev.to/kocreative/after-effects-favourite-expressions-part-1-linear-and-ease-14p1 | beginners, aftereffects, design, tutorial | ## Introduction
Now I've established the basics of After Effects, and why I like to use expressions in tandem with my work, I can finally start highlighting my favourite Expressions.
First up, is the linear() and ease() functions.
```
linear (t, tMin, tMax, value1, value2);
ease (t, tMin, tMax, value1, value2);
```
[ECAbrams](https://www.youtube.com/watch?v=OTivs6mMzpU) has a wonderful video tutorial on these functions. I highly recommend watching this video to understand how the functions work in detail.
In short, these functions can be used to remap values, using linear impolation, or easing. What does that mean? The **linear** function remaps values _evenly_ between two desired points, while the **easing** function remaps on a curve, slowly _easing_ in and out of the motion. This allows us to link one type of data to another, such as connecting rotation to opacity, or position to time.
Both functions require the same 5 arguements.
t = the parameter we are using to remap our value.
tMin = the minimum parameter value we are telling the function to look at.
tMax = the maximum parameter value we are telling the function to look at.
value1 = the first value we are remapping to.
value2 = the second value we are remapping to.
## Remapping Values Using Time
My favourite use of these functions is remapping values with time.
For this example, I will be looking at the position parameter.
I would like to create an expression, which would allow me to move my layer 500 pixels on the x axis, between the first and second seconds of the video. Taking into account that the position parameter needs to be an array, an x and y value, for After Effects to understand the coordinates, we could start with something like this:
```
var x = linear (time, 1, 2, value[0], value[0]+500);
[x, value[1]]
```
Let's break this down.
First, we create the variable x, to put the linear function inside.
The linear function is being told to look at "time" while written inside of the position parameter. It's tMin and tMax are set to 1 and 2 respectively, meaning that it will remap values between the first and second seconds of the video.
value[0] is the position's x value, while value[1] is the position's y value (and if this layer was 3D, position[2] would be the z value). So our value1 is set to our x coordinate's default value, while value2 is set to our default value plus 500.
Finally, we add our variable to our array, making sure to reference the default y value for our y coordinate.
If we want the motion to appear smoother, we can use the ease function instead:
```
var x = ease (time, 1, 2, value[0], value[0]+500);
[x, value[1]]
```
Now instead of a straight linear motion, our layer will ease from one position to the other.
## Using More Than One Instance Of Linear Or Ease
This works well enough when we only need to move between 2 values. But what if we wanted to create an expression to animate the layer in, and out again?
This is where we can get a little more creative.
Sticking with the position parameter, we need to set up 2 different ease functions, our "inAnimation" and our "outAnimation":
```
var inAnimation = ease(time, 1, 2, value[0], value[0]+500);
var outAnimation = ease(time, 4, 5, value[0]+500, value[0]);
```
Our inAnimation is the same function as our previous example. While our outAnimation has its value1 and value2 reversed, and is remapping between 4 and 5 seconds of our video.
Now that we have our in and out points established, we can use a simple if statement to toggle between the two functions:
```
if (time < 4) [inAnimation, value[1]]
else [outAnimation, value[1]]
```
With this statement, we are simply telling After Effects, "If time is less than 4 seconds, use the inAnimation variable. However, if time is equal to or more than 4 seconds, use the outAnimation variable. This allows us to create in and out motions, without keyframes.
We may also want to push this further by creating a variable for the in and out points of the animation:
```
var inPoint = 1;
var outPoint = 4;
var inAnimation = ease(time, inPoint, inPoint+1, value[0], value[0]+500);
var outAnimation = ease(time, outPoint, outPoint+1, value[0]+500, value[0]);
if (time < outPoint) [inAnimation, value[1]]
else [outAnimation, value[1]]
```
By creating variables for our in and out points, we can customise our expressions without having to change our values in several places. Because we want to keep our animation the same length as before, we simply have to tell After Effects that our tMax will always be our inPoint or outPoint + 1.
Or, if we want to experiment with the length of our animation, we can create a variable for that too:
```
var inPoint = 1;
var outPoint = 4;
var aniDuration = 1;
var inAnimation = ease(time, inPoint, inPoint+aniDuration, value[0], value[0]+500);
var outAnimation = ease(time, outPoint, outPoint+aniDuration, value[0]+500, value[0]);
if (time < outPoint) [inAnimation, value[1]]
else [outAnimation, value[1]]
```
Now we can change the value of our aniDuration variable, to reflect the duration of our in and out animations in seconds.

1,919,873 | Meu primeiro projeto REAL | Como tudo começou... Ano passado conheci a FCamara por um evento que eles organizaram... | 0 | 2024-07-11T18:15:39 | https://dev.to/leonardosf/meu-primeiro-projeto-real-284e | webdev, programming, learning, development | ## Como tudo começou...
Ano passado conheci a FCamara por um evento que eles organizaram junto ao GDG Santos. Descobri que toda quinta feira eles abrem o escritório para pessoas que quiserem estudar e trabalhar de lá. Desde então, toda semana estou por lá e numa dessas idas conheci o Lucas Batista, coordenador do projeto que vou falar sobre hoje.
A partir do Lucas, tive contato com a Ariane, que tinha uma demanda de um sistema para cadastro de vendas que era feito manualmente, e impossibilitava ou pelo menos dificultava muito a análise dos dados e as tomadas de decisão.
Temos reuniões semanais e a partir disso a Ariane
## Sobre o projeto
Pensando nisso, o Lucas me perguntou como eu preferiria fazer o projeto e optamos pelas tecnologias que eu tinha mais familiaridade. Utilizamos Nest.JS para o backend, com Prisma. No frontend, utilizamos React, mais especificamente a biblioteca de componentes React Mantine, que utiliza Typescript nos componentes.
## Funcionalidades
Atualmente, as funções de registrar, ver e deletar vendas estão implementadas. Estamos trabalhando com a parte de editar (que vou falar mais na seção de desafios) e posteriormente faremos a geração dos relatórios e autenticação.
Esse é um vídeo do fluxo de adição, visualização e deleção dos registros e vendas.
## Desafios
### Backend e uso de ORM
Por mais que eu estivesse familiarizado com o Nest, não foi tão natural escrever um projeto do zero. Demorei algum tempo a entender como validar as requisições do backend e como usar o Prisma, coisa que nunca havia feito.
### Dados e formas normais
No início, pensar nas tabelas, como elas se comunicariam, porque elas se comunicariam, foi algo que demorou um tempo, alguns testes e vários migrations.
### React e Typescript
Agora no frontend as coisas ficaram mais complicadas. Fazia bastante tempo que não mexia com react e lembrar como funcionava demorou um pouco. O typescript foi bem desafiador de implementar, mas fui obrigado devido a melhor funcionalidade das ferramentas que havia escolhido, então tive que estudar mais sobre o conceito de interfaces e tipos.
### React - Passagem de dados entre componentes
Porém tive e estou tento alguns problemas para comunicar entre os componentes, por exemplo, como mandar os dados de um componente filho para o pai, para que ele atualize quantas vendas tem, por exemplo.
### Versionamento
Como faço o projeto sozinho é mais fácil, porém entender o fluxo de trabalho é algo que ainda tenho algumas dificuldades, criação de branchs para funcionalidades e correção de bugs, merge das branchs, resolução de conflitos é uma coisa que estou melhorando.
## Aprendizados
### Comunicação e Gestão de Projetos
O trabalho no projeto me ajudou a melhorar minha capacidade de comunicação e a gestão de expectativas com o cliente. Alinhar as expectativas com o cliente e traduzir isso em código.
### Melhoria Técnica
Aprendi bastante sobre a utilização de ORM com Prisma e como hospedar serviços na Vercel. Também melhorei minha habilidade de criar e gerenciar CRUDs no backend e frontend.
### Trabalho com Ferramentas Modernas
Implementar Typescript no projeto, mesmo com a curva de aprendizado, trouxe muitos benefícios em termos de segurança e qualidade do código. Aprendi a importância das interfaces e tipos, o que me ajudou a escrever um código mais robusto e certamente será mais fácil de mantê-lo.
### Gestão de Versionamento
Entender e implementar um fluxo de trabalho com Git foi um grande aprendizado. Agora, consigo criar branches para novas funcionalidades, corrigir bugs e resolver conflitos de código com mais eficiência, o que facilita o desenvolvimento contínuo e colaborativo.
### Próximos Passos
Pretendo continuar aprimorando minhas habilidades técnicas, especialmente em áreas que ainda sinto dificuldade, a comunicação entre os componentes do React, a elaboração de testes, o versionamento de código. Além disso, quero explorar mais ferramentas e práticas como subir o banco de dados na nuvem.
## Agradecimentos
Algumas pessoas foram fundamentais para esse processo, especificamente com tecnologia, por me ajudarem de N formas a aprender algo novo:

RFC SSR Hybrid... | 0 | 2024-07-11T14:44:37 | https://dev.to/this-is-angular/episode-2427-ssr-hybrid-rendering-full-ssr-guide-20gj | webdev, javascript, programming, angular | We got a new RFC focusing on "hybrid rendering" and a full SSR guide.
{% embed https://youtu.be/a4ABBJAwj0Y %}
## RFC SSR Hybrid Rendering
Although Angular 18.1 was released this week (coverage will follow in the next episode), a new RFC lays out future features for SSR.
The RFC foresees a separate router configuration file where we can define the rendering strategy per route.
That could be
- Pre-rendering (**SSG**): The rendering happens already during the build.
- Server-side rendering (**SSR**): The rendering occurs on the server on demand.
- Client-side rendering (**CSR**): This is without server, everything happens in the browser.
That's also why this RFC is called "hybrid rendering," not to be confused with hybrid change detection, which we have since Angular 18.
Pre-rendering will also allow users to define the routes dynamically via an asynchronous function. The RFC should fix some issues that users raised in the past.
RFC means that we are all invited to provide feedback.
Alan Agius, the author of the RFC, also mentioned that File-Based routing, as we find it in Analog, is not off the table but a topic for the future.
https://github.com/angular/angular/discussions/56785
## Full SSR Guide
Alexander Thalhammer has written an article that covers everything you need to know when you want to start using SSR.
Starting with the configuration, how to debug it, and things you have to be aware of. For example, the two render hooks that only run on the browser and how to work around the missing document or window object on the server.
He also mentions the meta-framework analog and how SSR and Micro Frontends work together.

1,919,877 | Oh CommonJS! Why are you mESMing with me?! Reasons to ditch CommonJS | It was a normal patching day. I patched and upgraded my npm dependencies without making code changes,... | 0 | 2024-07-12T08:21:24 | https://dev.to/jolodev/oh-commonjs-why-are-you-mesming-with-me-reasons-to-ditch-commonjs-enh | javascript, typescript, esm, commonjs | It was a normal patching day. I patched and upgraded my npm dependencies without making code changes, and suddenly, some of my unit tests failed.
Wtf!
My tests failed because `Jest encountered an unexpected token`; they failed because Jest cannot handle ESM-only packages out of the box. In fact, Jest is written in CommonJS.
But what does that mean? To do so, we need to understand why CommonJS and ESM exist.
## Why Do We Need Module Systems?
In the early days of web development, JavaScript was mainly used to manipulate the Document Object Model (DOM) with libraries like jQuery. However, the introduction of Node.js also led to JavaScript being used for server-side programming. This shift increased the complexity and size of JavaScript codebases. As a result, there arose a need for a structured method to organize and manage JavaScript code. Module systems were introduced to meet this need, enabling developers to divide their code into manageable, reusable units[^1].
### The Emergence of CommonJS
CommonJS was established in 2009, originally named ServerJS[^2]. It was designed for server-side JavaScript, providing conventions for defining modules. Node.js adopted CommonJS as its default module system, making it prevalent among backend JavaScript developers. CommonJS uses `require` to import and `module.exports` to export modules. All operations in CommonJS are synchronous, meaning each module is loaded individually.
### The Rise of ESM (ECMAScript Modules)
In 2015, ECMAScript introduced a new module system called ECMAScript Modules (ESM), primarily targeting client-side development. ESM uses `import` and `export` statements, and its operations are asynchronous, allowing modules to be loaded in parallel[^3]. Initially, ESM was intended for browsers, whereas CommonJS was designed for servers. It became more and more a standard for the JS ecosystem. Nowadays, modern JavaScript runtimes support both module systems. Browsers began supporting ESM natively in 2017. Even Typescript adapted the ESM syntax, and whenever you learn it, you also learn ESM subconsciously.
## CommonJS is here to stay
The truth is that there are many more CommonJS (CJS)- only packages than ESM-only packages[^4].
However, there is a clear trend. The number of ESM-only or dual module packages is on the rise, while fewer CJS-only packages are being created. This trend underscores the growing preference for ESM and raises the question of how many of the CJS-only packages are actively maintained.
### Comparison
An interesting comparison between CommonJS and ESM involves performance benchmarks. Due to its synchronous nature, CommonJS is faster when directly using require and import statements. Let's consider the following example:
```javascript
// CommonJS -> s3-get-files.cjs
const s3 = require('@aws-sdk/client-s3');
new s3.S3Client({ region: 'eu-central-1' });
// ESM -> s3-get-files.mjs
import { S3Client } from '@aws-sdk/client-s3';
new S3Client({ region: 'eu-central-1' });
```
I used the [aws-sdk S3-Client](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/client/s3/) because it has dual module support. Here we instantiate the client and then execute it with `node`:
```sh
hyperfine --warmup 10 --style color 'node s3-get-files.cjs' 'node s3-get-files.mjs'
Benchmark 1: node s3-get-files.cjs
Time (mean ± σ): 82.6 ms ± 3.7 ms [User: 78.5 ms, System: 16.7 ms]
Range (min … max): 78.0 ms … 93.6 ms 37 runs
Benchmark 2: node s3-get-files.mjs
Time (mean ± σ): 93.9 ms ± 4.0 ms [User: 98.3 ms, System: 18.1 ms]
Range (min … max): 88.1 ms … 104.8 ms 32 runs
Summary
node s3-get-files.cjs ran
1.14 ± 0.07 times faster than node s3-get-files.mjs
```
As you can see, the `s3-get-files.cjs` and, thus, CommonJS run faster.
I got inspired by [Buns Blogpost](https://bun.sh/blog/commonjs-is-not-going-away).
However, when you want to productionize your JS library, you need to bundle it. Otherwise, you will ship all the `node_modules`. Is used [`esbuild`](https://esbuild.github.io/) because it is able to bundle to CJS and ESM. Now, let's run the same benchmark with the bundled version.
```sh
hyperfine --warmup 10 --style color 'node s3-bundle.cjs' 'node s3-bundle.mjs'
Benchmark 1: node s3-bundle.cjs
Time (mean ± σ): 62.1 ms ± 2.5 ms [User: 53.8 ms, System: 6.7 ms]
Range (min … max): 59.5 ms … 74.5 ms 45 runs
Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
Benchmark 2: node s3-bundle.mjs
Time (mean ± σ): 45.3 ms ± 2.2 ms [User: 38.1 ms, System: 5.6 ms]
Range (min … max): 43.0 ms … 59.2 ms 62 runs
Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
Summary
node s3-bundle.mjs ran
1.37 ± 0.09 times faster than node s3-bundle.cjs
```
As you can see, the `s3-bundle.mjs` is now faster than the `s3-bundle.cjs`. The ESM file is now even faster than the unbundled CommonJS file because it results in smaller file sizes and faster load times due to efficient tree-shaking—a process that removes unused code.
## Embrace ESM!
The future of JavaScript modules is undoubtedly leaning towards ESM. This starts when creating a new NodeJS project or even a React project. Every tutorial and article uses the `import`—statement, which is thus ESM. Despite many existing CommonJS packages, the trend is shifting as more developers and maintainers adopt ESM for its performance benefits and modern syntax. Another question is also how many of these CJS-only projects are still maintained.
ESM is a standard that works in any runtime, such as NodeJS, Bun, or Deno, and in the browser without running on a server. It is unnecessary to convert via Babel to CommonJS because the browser understands ESM. You can still use Babel to convert to a different ECMAScript version, but you shouldn't convert to CJS.
You should develop in ESM-only because every runtime now and browser newer than 2017 understands ESM.
If your code breaks, you may have legacy issues. Consider using different tooling or packages. For example, you can migrate from Jest to [`vitest`](https://vitest.dev/) or from ExpressJS to [`h3`](https://h3.unjs.io/). The syntax remains the same; the only difference is the import statement.
**Key Takeaways**:
- **Smaller Bundles**: ESM produces smaller bundles through tree-shaking, leading to faster load times.
- **Universal Support**: ESM is supported natively by browsers and JavaScript runtimes (Node.js, Bun, Deno).
- **Future-Proof**: With ongoing adoption, ESM is positioned as the standard for modern JavaScript modules.
To get started, you can follow this [Gist](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c) or get an inspirational learning [here](https://blog.isquaredsoftware.com/2023/08/esm-modernization-lessons/).
For a better JavaScript Future, Embrace ESM!

1,919,881 | What Is Pulumi And How To Use It | Imagine managing your cloud infrastructure using the programming languages you already love—Python,... | 0 | 2024-07-11T15:01:29 | https://www.env0.com/blog/what-is-pulumi-and-how-to-use-it-with-env0 | pulumi, infrastructureascode, devops, cloudcomputing | Imagine managing your cloud infrastructure using the programming languages you already love—Python, Go, JavaScript, you name it. No more wrestling with YAML, JSON, or HCL (HashiCorp Configuration Language) files!
Pulumi gives you that power, offering a robust CLI and service backend to manage both state and secrets. It's like the Swiss Army knife for cloud infrastructure, supporting all the major providers like AWS, Azure, and Google Cloud.
Today we're diving into the world of Pulumi and its integration with env0. We'll explore what Pulumi is, its features, how to set it up, and even throw in a real-world example (provisioning an EKS cluster). Also, we’ll weigh the pros against the cons and look at how it stacks up against other options. So buckle up; this is going to be a fun ride!
**Requirements:**
* A GitHub account
* An AWS account
* An env0 account
* A Pulumi account
**TL;DR:** You can find [the main repo here.](https://github.com/samgabrail/env0-pulumi)
**What is Pulumi?**
-------------------
Pulumi is an open source [Infrastructure-as-Code](https://www.env0.com/blog/infrastructure-as-code-101) (IaC) framework that provisions resources utilizing common programming languages. Pulumi also supports the major cloud providers: AWS, Azure, and Google Cloud. Its leaning on common languages eliminates the time it would otherwise take to get used to a new domain-specific language like HCL.
If you're wondering how it stacks up against Terraform, check out my previous blog comparing [Pulumi vs. Terraform](https://www.env0.com/blog/pulumi-vs-terraform-an-in-depth-comparison). But the main benefits come in three main cores: the Pulumi SDK(s), the service backend, and finally the automation API.
### **Pulumi SDKs**
First up, the SDKs. Pulumi's SDKs are what make it super versatile. These SDKs allow you to use languages like Python, JavaScript, TypeScript, Go, or .NET for defining and deploying your infrastructure. This is super cool because it means you can use the same language you're already comfortable with for your application development.
That all means that you end up with the following advantages: strong familiarity with the core languages, a long list of library resources (according to language), and reusable custom abstractions.
### **Pulumi Service Backend**
Pulumi's SaaS offering comes replete with CI/CD integrations, Policy-as-Code, role-based access, and state management.
**State Management** – Safely stores and manages the [state](https://www.pulumi.com/docs/concepts/state/) of your infrastructure. This means less headache worrying about where your infrastructure's "truth" lives. There is also an option for self-managed state through your own cloud account on AWS, Azure, or GCP.
**Collaboration Features** – You can collaborate with your team on infrastructure updates, with features like [RBAC](https://www.pulumi.com/docs/pulumi-cloud/access-management/teams/), stacks history, and more.
**Policy-as-Code** – Enforce security, compliance, and best practices across your infrastructure using Pulumi’s Policy as Code offering called [CrossGuard](https://www.pulumi.com/docs/using-pulumi/crossguard/).
**CI/CD Integration –** [Pulumi CI/CD integrations](https://www.pulumi.com/docs/pulumi-cloud/deployments/ci-cd-integration-assistant/#:~:text=The%20CI%2FCD%20integration%20assistant,to%20Organizations%2C%20not%20personal%20accounts.) work with popular systems like GitHub Actions, GitLab CI, Jenkins, TravicCI, AWS Code Services, Azure DevOps, and more.
### **Automation API**
This [Automation API](https://www.pulumi.com/docs/using-pulumi/automation-api/) can embed Pulumi directly into your application code, offering a hassle-free way to manage infrastructure.
In essence, this concept encapsulates the core functionalities offered by the Pulumi Command Line Interface (CLI), such as executing commands like `pulumi up`, `pulumi preview`, `pulumi destroy`, and `pulumi stack init`.
However, it extends beyond this by offering enhanced flexibility and control. This approach is designed to be strongly typed and secure, facilitating the use of Pulumi within embedded environments, for instance, within web servers.
Importantly, this method eliminates the need for running the CLI through a shell process, streamlining operations, and integrating infrastructure management more seamlessly into application environments.
### **Pulumi Features**
Alright, let’s dig into some of the Pulumi concepts and features that it offers:
#### **1. Component Resources**
Pulumi lets you define reusable building blocks known as "component resources." These are like your typical cloud resources but bundled with additional logic. If you are familiar with Terraform, these would be your modules.
#### **2. Stack References**
Manage dependencies between multiple Pulumi stacks effortlessly. This feature is a real game-changer for managing infrastructure at scale.
#### **3. Templates and Packages**
Think of these as the ultimate cheat codes for your IaC. Instead of starting from scratch, you can kick things off with a pre-baked setup. Here’s why they're great:
* **Speedy Setup**: No more blank-slate syndrome. You’ve got a starting point that’s not just a blank file – it’s a springboard that gets you coding your infra in record time.
* **Best Practices**: These templates aren't just thrown together – they're crafted with best practices in mind. So you're not just starting faster, you're starting smarter.
* **Learning Resources**: New to Pulumi or a particular cloud service? Templates can be great learning tools, showing you the ropes of how things are structured and pieced together.
**How to Install Pulumi**
-------------------------
Alright, time to get our hands dirty. Installing Pulumi is a breeze. You can reference this from [Pulumi's documentation.](https://www.pulumi.com/docs/install/)
Since I'm running this in my Windows for Subsystem Linux environment, I can run the install script as shown:
curl -fsSL https://get.pulumi.com | sh -s -- --version 3.91.1
**Pulumi Stack Example**
------------------------
Let's get into the meat and potatoes: stacks. A Pulumi stack is essentially an isolated, independently configurable instance of a Pulumi program. Let's first work with the Pulumi CLI then later we'll see how to use [env0](https://www.env0.com/).
### **Create a New Pulumi Project**
First, create a Pulumi project by creating a new directory and running the `pulumi new` command with the `kubernetes-aws-python` Pulumi template.
mkdir Pulumi-EKS
cd Pulumi-EKS
pulumi new kubernetes-aws-python
Continue by providing a project name, description, and stack name along with the AWS region and some other parameters.
Pulumi installs the necessary dependencies and your new project is ready.
### **Run Pulumi**
Next, make sure you export your AWS cloud credentials as environment variables and run `pulumi up`.
export AWS_ACCESS_KEY_ID=your-access-key-id
export AWS_SECRET_ACCESS_KEY=your-secret-access-key
pulumi up
Read what Pulumi is about to do, then answer yes when asked if you want to perform this update.
Now, Pulumi will start to provision resources and you will see the resources get created in the terminal as shown below.
### **Observe the Output Results**
If all goes well, you should have your new EKS cluster up and running. You can also check the Pulumi UI for your new stack where you can view all the resources created along with the output.
You can view the output in the UI or the CLI for the **vpcId** and the **kubeconfig**.
### **Access the EKS Cluster**
To get the **kubeconfig** for the EKS cluster, run the following command:
echo $(pulumi stack output kubeconfig) > mykubeconfig
export KUBECONFIG=./mykubeconfig
Now run kubectl commands to interact with the EKS cluster:
kubectl get nodes
Congratulations! You've successfully provisioned an EKS cluster in AWS.
### **Examine the Infrastructure Code**
Take a look at the actual code that provisions our EKS cluster. Notice how it's written in simple Python. I could have built the cluster from scratch by calling on each resource, but why reinvent the wheel? There is an excellent Pulumi package called [Amazon EKS in the Pulumi Registry](https://www.pulumi.com/registry/packages/eks/). I decided to go with this.
As you see, in under 40 lines of code, we have our EKS cluster defined:.
import pulumi
import pulumi_awsx as awsx
import pulumi_eks as eks
# Get some values from the Pulumi configuration (or use defaults)
config = pulumi.Config()
min_cluster_size = config.get_float("minClusterSize", 3)
max_cluster_size = config.get_float("maxClusterSize", 6)
desired_cluster_size = config.get_float("desiredClusterSize", 3)
eks_node_instance_type = config.get("eksNodeInstanceType", "t3.medium")
vpc_network_cidr = config.get("vpcNetworkCidr", "10.0.0.0/16")
# Create a VPC for the EKS cluster
eks_vpc = awsx.ec2.Vpc("eks-vpc",
enable_dns_hostnames=True,
cidr_block=vpc_network_cidr)
# Create the EKS cluster
eks_cluster = eks.Cluster("eks-cluster",
# Put the cluster in the new VPC created earlier
vpc_id=eks_vpc.vpc_id,
# Public subnets will be used for load balancers
public_subnet_ids=eks_vpc.public_subnet_ids,
# Private subnets will be used for cluster nodes
private_subnet_ids=eks_vpc.private_subnet_ids,
# Change configuration values to change any of the following settings
instance_type=eks_node_instance_type,
desired_capacity=desired_cluster_size,
min_size=min_cluster_size,
max_size=max_cluster_size,
# Do not give worker nodes a public IP address
node_associate_public_ip_address=False,
# Change these values for a private cluster (VPN access required)
endpoint_private_access=False,
endpoint_public_access=True
)
# Export values to use elsewhere
pulumi.export("kubeconfig", eks_cluster.kubeconfig)
pulumi.export("vpcId", eks_vpc.vpc_id)
Pulumi makes it very easy to choose between many languages right in the documentation.
If you need to tweak the cluster configuration, it's easy to do so with the very [well-documented eks.Cluster package](https://www.pulumi.com/registry/packages/eks/api-docs/cluster/).
### **Pulumi Configuration Files**
When we ran the `pulumi new kubernetes-aws-python` command, Pulumi 1) created a new folder for us, 2) downloaded dependencies in a virtual environment for Python, and 3) also created two config files.
Let's take a look at them now.
#### **1\. pulumi.yaml**
This file acts as the manifest for your Pulumi project. It's a key part of the project configuration and provides metadata about the project itself.
name: my-pulumi-eks-env0
runtime:
name: python
options:
virtualenv: venv
description: A Python program to deploy a Kubernetes cluster on AWS
Here's what each part of the content you've provided does:
* **name** – This is the name of your Pulumi project. When you run `pulumi new`, it sets this name, and it's used as a default prefix for the resources Pulumi creates.
* **runtime** – This specifies the runtime environment that your Pulumi program is expected to run in. In your case, it's set to **python**, meaning the Pulumi CLI expects your Infrastructure-as-Code to be written in Python.
* **options** – These are additional settings related to the runtime environment.
* **virtualenv** – This option tells Pulumi to use a Python virtual environment located in the **venv** directory within your project directory. This is important for Python-based projects to ensure dependencies are isolated from other Python projects on the same system.
* **description** – This provides a human-readable description of what the Pulumi project does. It's a string that helps you and others understand the project's purpose at a glance.
So, when you initialize a new Pulumi stack or when Pulumi interacts with your project, it uses this file to understand the project structure, runtime requirements, and other metadata that influence how it deploys and manages your infrastructure resources.
#### **2\. pulumi.dev.yaml**
When you run the _pulumi new_ command and answer the setup wizard's questions, Pulumi automatically saves these answers as configurations in the **pulumi.dev.yaml** file. This file acts as a record of the initial setup parameters you specified for your project.
Now, if you enter commands or make changes at a different time (i.e., not during the initial Pulumi new setup) these changes won't automatically update the **pulumi.dev.yaml** file. Instead, you have two main alternatives for updating configurations after the initial setup:
1. **Manual Editing** – You can directly edit the **pulumi.dev.yaml** file to change or add configurations. This is like tweaking the settings of your project by hand.
2. **Using Pulumi CLI Commands** – You can use specific Pulumi CLI commands to update your configuration. For example, if you want to change the AWS region, you could use a command like pulumi config set aws:region us-west-2. This command updates the configuration in your **pulumi.dev.yaml** file without you having to manually edit the file.
Here is the content of the file:
config:
aws:region: us-east-1
my-pulumi-eks-env0:desiredClusterSize: "2"
my-pulumi-eks-env0:eksNodeInstanceType: t2.small
my-pulumi-eks-env0:maxClusterSize: "3"
my-pulumi-eks-env0:minClusterSize: "1"
my-pulumi-eks-env0:vpcNetworkCidr: 10.0.0.0/16
To clean up simply run `pulumi destroy`.
**Pros and Cons of Using Pulumi**
---------------------------------
### **Pros**
1. **Language Choice** – Use your favorite programming language.
2. **Rich Ecosystem** – Supports a ton of cloud providers.
3. **Dynamic Providers** – Extend its capabilities as you see fit.
### **Cons**
1. **Language Overload** – Sometimes, choosing a language can be a burden.
2. **Learning Curve** – If you're coming from dedicated DSL tools like Terraform's HCL, there might be an initial hump.
**Pulumi Alternatives**
-----------------------
The most obvious alternative to Pulumi is Terraform. But hey, keep an eye out for [OpenTofu](https://opentofu.org/), an upcoming open-source alternative following a BSL license change. [Crossplane](https://crossplane.io) is another alternative for those who enjoy building infrastructure using Kubernetes CRDs. Check out more details below.
### **1. Terraform**
**Overview:** Terraform is a big player in the IaC field. It uses its own domain-specific language, HCL (HashiCorp Configuration Language), which is designed to describe infrastructure in a declarative way.
**Why It's Popular:** Terraform's been around for a while and has a huge community and support base. Plus, it works across many cloud providers, making it super versatile.
**Key Differences from Pulumi:** Unlike Pulumi, Terraform isn’t based on conventional programming languages. So, if you're not into learning HCL, it might be a bit of a curve.
### **2. Crossplane**
Crossplane is perfect for those who are all-in with Kubernetes. It allows you to manage your infrastructure using Kubernetes CRDs (Custom Resource Definitions).
If you’re comfortable with Kubernetes and want to manage cloud resources as Kubernetes objects, Crossplane is your go-to. Being Kubernetes-focused, it fits well in ecosystems already heavy with Kubernetes usage and has a growing community.
### **Thoughts**
Each of these alternatives has its own flavor. Terraform is the established giant with a dedicated language, OpenTofu promises to always be open-source along with new approaches to IaC, and Crossplane merges the worlds of Kubernetes and IaC.
Depending on your needs, comfort with certain technologies, and the specifics of your infrastructure, one of these might be a better fit for you than Pulumi.
**Tutorial: Using Pulumi with env0**
------------------------------------
Now let's see how to use [env0](https://www.env0.com/) to create the same Pulumi stack. We will create the same EKS cluster but this time by using env0 to trigger Pulumi.
Let's start by creating a new project in [env0](https://www.env0.com/).
Next, you'll need to create a Pulumi template as shown:
Then connect to your VCS. Make sure to select the Pulumi folder, in our case **Pulumi-EKS.**
Under variables, add your PULUMI_ACCESS_TOKEN environment variable.
Then finally, make sure this template is deployable in our 'eks-demo' project.
### **AWS Cloud Provider Credentials**
Make sure you have your AWS credentials set up in the Project settings
### **Create an Environment**
Now we're ready to create a new environment. Head over to 'Project Environments' then create a new e.
When you see the **eks-template**, click the 'Run Now' button. There are some options to use such as enabling drift detection and the ability to automatically destroy the environment. When you're ready click the **Run** button.
Notice in the deployment logs how we have a 'Before: Pulumi Preview' step. This is defined in the **env0.yaml** file at the root of our repo to provide our configuration variables.
Below you can see how our **env0.yaml** looks like. Notice that we are specifying the same configuration variables that were in our **pulumi.dev.yaml** file.
version: 1
deploy:
steps:
pulumiPreview:
before:
- cd Pulumi-EKS && pulumi config set-all \
--plaintext aws:region=us-east-1 \
--plaintext my-pulumi-eks-env0:desiredClusterSize="2" \
--plaintext my-pulumi-eks-env0:eksNodeInstanceType=t2.small \
--plaintext my-pulumi-eks-env0:maxClusterSize="3" \
--plaintext my-pulumi-eks-env0:minClusterSize="1" \
--plaintext my-pulumi-eks-env0:vpcNetworkCidr=10.0.0.0/16
If you left the option to approve the plan automatically unchecked, you will need to confirm the execution of the \[,code\]pulumi up\[.code\] command.
### **View the Output**
Finally, once the deployment completes, you can view the outputs under the 'Resources' tab.
Once again, to access the Kubernetes cluster, you can simply save the kubeconfig in a file and export as an environment variable as shown below:
export KUBECONFIG=./mykubeconfig
kubectl get nodes
NAME STATUS ROLES AGE VERSION
ip-10-0-144-143.ec2.internal Ready 73m v1.28.2-eks-a5df82a
ip-10-0-29-122.ec2.internal Ready 73m v1.28.2-eks-a5df82a
Congratulations! You've just used env0 to deploy the Pulumi stack and provision an EKS cluster, and it probably took less than 5 minutes.
To clean up, just click the 'Destroy' button. One click and it gone.
**In Summary**
--------------
We've covered a lot of ground in this post—from the nuts and bolts of what Pulumi is to its nifty features, and even how it plays nice with [env0](https://www.env0.com/).
If you're in the DevOps or Platform Engineering space, Pulumi offers a refreshing take on infrastructure-as-code. By marrying traditional programming languages with cloud resources, you get a level of flexibility and power that’s hard to beat.
So, what's the takeaway? If you’re looking to step up your infrastructure game, Pulumi is worth a shot.
Not ready for your entire team to move from Terraform to Pulumi? That's the benefit of a framework agnostic IaC platform such as env0.
Here are some of the key features that I like about [env0](https://www.env0.com/):
* **Drift detection –** env0 provides drift detection that can help you detect drifts and alert you about them automatically.
* **Governance –** our platform allows you to define custom policies and guardrails to both secure and keep your infrastructure compliant.
* **Multiple frameworks –** env0 supports multiple frameworks such as Pulumi, Terraform, OpenTofu, and more.
* **Ephemeral environments –** Developers can set up an environment with a timer to self-destruct reducing wasted resources.
* **Flexibility –** With pre- and post-hooks that reduce the need for a full external CI/CD pipeline.

YouTube. It's a great way to waste a lot of time. Especially when ill and you can't do anything else.
I've watched loads of car, ASMR cleaning, tech and purely random content over the last 18 months. Recently I've watched a huge amount of 3D Printing content (because of my new toy - I want to learn how to use it right).
And... Keyboards. I'm a geek, unashamedly, and watching people build and mod keyboards is awesome! The difference that you can make to a keyboard just by a few simple things is amazing.
I did want to treat myself to a new keyboard - I've had my current Skarkoon Purewriter RGB for about 6 years now. Whilst it is great to usee, it can be a little finiky, and, well, I just wanted to try something different.
But... My budget is being spent elsewhere at the moment, trying to get a NAS big enough to store our movie collection, so that we can watch them without having to sort through the discs... Ho-hum choices have to be made. Luxury problems, I know.
Instead I started thinking about other options. What changes can I make to my current keyboard to make it better. There are lots of limitations:
- It is low profile, so there are limited choices in hardware, and I wasn't sure if I could even change my switches
- Sharkoon use Kailh switches which mean my choice of keycaps is limited
- I have no money to spend so I have to start off with things around the house before I move onto actually byuing anything
Oh, and my brain means that I don't plan these things. I had the idea at 11am and by lunch they keyboard was in bits - so no pictures I'm afraid (it really should have been a video! I can always take it apart again, let me know if it would be fun to watch).
Dismantling was easier than I expected. I removed all the keykaps (after taking a picture so that I could put them back in the right place) and undid some screws. The top plate then just lifted off and I could see what what inside.
However, this is where the problems started. The switches are soldered, so I couldn't do anything with them. They also seem to be soldered from the other side of the top panel - so I can't even take out the PCB... Hmm...
And lastly, the stabalisers look nothing like I have seen on any keyboard channel - so I assume that they are not interchangable with other sets. My options are looking more and more limited.
Literally the only thing that I could so was add sound deadening material to the base and see if I could change the clacky sounds to more of a thonk.
So I thought about what I could fill it with. I had some sticky door edge draft excluder (rubber foam stuff - technical term) left from some DIY... That covered about half the bottom of the case.
Put it back together and OMG! The difference was night and day. All of a sudden all of the hollow clackyness had gone and some satisfying thonking (more technical terms) had replaced it. All whilst still keeping the clickyness of the clicky switches that I love! But it wasn't perfect. In the spaces wehere I has no rubber foam you could hear the difference in the sound of they keys. So I had another look and... Bubble wrap was all I could find - from some printer parts that were delivered.
So I cut that into rectangles to put into the rest of the keyboard base and BOOM! the rest of it sounded pretty similar. At some point I will get some more draft exluder and stream replacing the bubble wrap - but for now... I'm over the moon with the difference in sound!
Oh, I also took the time to clean the keys with alcohol. Wow, 10 years of grime! Considering that they didn't look dirty, they were actually pretty gross judging by the cotton buds at the end 🫣
For now I'm done with this keyboard. The only other thing I can think of is adding some Modge Podge/PVA glue to the keycaps to make them more solid. But that is for another time.
I do think that I am going to revisit the custom keyboard idea later in the year to see what options there are to really make a personal keyboard! There are some beautiful options out there!
If you want to look at how you can improve your keyboard then here are some awesome channels that I can recomend following:

1,919,886 | How to upload an image into firebase storage | We will learn how to upload an image file into firebase using firebase storage like imageBB or... | 0 | 2024-07-11T15:06:35 | https://dev.to/rahatfaruk/how-to-upload-an-image-into-firebase-storage-58cl | webdev, beginners, firebase, react | We will learn how to **upload an image file into firebase** using firebase storage like imageBB or postimages. We are gonna use firebase web sdk in our react-js project.
Steps:
- Create a new firebase project.
- setup firebase storage. Choose `test mode` option to get started. In notes section, I have shown how to use it longer.
- Setup your local project folder in your computer. Setup firebase config file to link up with your firebase-project.
- Initialize firebase-storage service:
```js
// >> inside firebase config file
import { getStorage } from 'firebase/storage';
// init storage service
const fbStorage = getStorage(app)
export {fbStorage}
```
- Now we can create a form with an input (type- file) element and a submit button so that we can upload image from our computer. Add submit event handler to the form (handleUploadImage).
```html
<!-- upload form -->
<form onSubmit={handleUploadImage}>
<input type="file" name="imageInput" />
<button>Upload</button>
</form>
```
The form looks like this (apply your own styles):
- We can choose an image from our computer by clicking "choose file" btn; after choosing image, we should click "upload" button. Then the form fires "onSubmit" event and invoke "handleUploadImage" function. Define "handleUploadImage" function:
```js
import { getDownloadURL, ref, uploadBytes } from "firebase/storage";
import { fbStorage } from "../../firebase.config"; // NB: define your own path
const handleUploadImage = async e => {
// prevent deafult form submit
e.preventDefault()
// get imageInput element inside form
const imageInput = e.target.imageInput
// imageInput is an array of files. we choose the fist file (which is image file)
const imageFile = imageInput.files[0]
// validate: show alert if no image is selected
if (!imageFile) {
alert('please, select a image!')
return
}
// create file path ref for firebase storage.
// if image filename is "eagle.jpg"; then the path would be "images/eagle.jpg"
const filePathRef = ref(fbStorage, `images/${imageFile.name}`)
// upload the image file into firebse storage
const uploadResult = await uploadBytes(filePathRef, imageFile)
// finally get image url which can be used to access image from your website
const imageUrl = await getDownloadURL(filePathRef)
// [ TODO: put your code here whatever you want to do with the "imageUrl" ]
// reset form (optional)
e.target.reset()
}
```
Now, you have successfully uploaded the image into firebase storage.
If you want to find the image in firebase website: open your firebase project (from firebase website) > firebase storage > Files (tab) > images > your images lives here. From here you can manage (delete, upload) your images manually.
### Notes:
#### Use storage for longer period:
`test mode` only keeps your storage active for 1 month. You must setup storage rules to use longer period. The easiest way is: go to firebase storage > select "Rules" tab > reset your date as new future date to use it longer. You have to learn security rules to use it more effectively. If you don't update security rules, anyone who has your firebase credentials can modify your data!

JavaScript is a cornerstone of modern web development, powering dynamic websites and applications. While many developers familiar with the basic and widely used features of JavaScript, numerous hidden features often go unnoticed. These lesser-known features can make your code more concise, readable, and powerful.
In this article, we'll explore some hidden JavaScript features. From the nullish coalescing operator to Map and Set objects, each feature includes practical examples and best practices. Utilizing these features can help you write cleaner, more efficient code and tackle complex problems easily.
Whether you're a seasoned developer or a beginner, this article will introduce you to underutilized JavaScript capabilities. By the end, you'll have new techniques to elevate your coding skills with Javascript.

- [The Right Way to Clone Nested Object/Array (Deep Clone) in Javascript](/deep-clone-nested-object-array-in-javascript/)
## Lesser-known Javascript Features
### 1. Nullish Coalescing Operator
The nullish coalescing operator (`??`) is used to provide a default value when a variable is `null` or `undefined`.
#### Code Example:
```javascript
let foo = null;
let bar = foo ?? 'default value';
console.log(bar); // Output: 'default value'
```
Use the nullish coalescing operator to handle cases where `null` or `undefined` values may appear, ensuring that your code runs smoothly with default values.
### 2. Optional Chaining
The optional chaining operator (`?.`) allows safe access to deeply nested object properties, avoiding runtime errors if a property does not exist.
#### Code Example:
```javascript
const user = {
profile: {
name: 'Alice'
}
};
const userProfileName = user.profile?.name;
console.log(userProfileName); // Output: 'Alice'
const userAccountName = user.account?.name;
console.log(userAccountName); // Output: undefined
```
Use optional chaining to avoid errors when accessing properties of potentially `null` or `undefined` objects, making your code more robust.
### 3. Numeric Separators
Numeric separators (`_`) make large numbers more readable by visually separating digits.
#### Code Example:
```javascript
const largeNumber = 1_000_000;
console.log(largeNumber); // Output: 1000000
```
Use numeric separators to improve the readability of large numbers in your code, especially for financial calculations or large datasets.
### 4. Promise.AllSettled
`Promise.allSettled` waits for all promises to settle (either fulfilled or rejected) and returns an array of objects describing the outcome.
#### Code Example:
```javascript
const promises = [Promise.resolve('Success'), Promise.reject('Error'), Promise.resolve('Another Success')];
Promise.allSettled(promises).then((results) => {
results.forEach((result) => console.log(result));
});
// Output:
// { status: 'fulfilled', value: 'Success' }
// { status: 'rejected', reason: 'Error' }
// { status: 'fulfilled', value: 'Another Success' }
```
Use `Promise.allSettled` when you need to handle multiple promises and want to ensure that all results are processed, regardless of individual promise outcomes.
### 5. Private Class Fields
Private class fields are properties that can only be accessed and modified within the class they are declared.
#### Code Example:
```javascript
class MyClass {
#privateField = 42;
getPrivateField() {
return this.#privateField;
}
}
const instance = new MyClass();
console.log(instance.getPrivateField()); // Output: 42
console.log(instance.#privateField); // Uncaught Private name #privateField is not defined.
```
Use private class fields to encapsulate data within a class, ensuring that sensitive data is not exposed or modified outside the class.
### 6. Logical Assignment Operators
Logical assignment operators (`&&=`, `||=`, `??=`) combine logical operators with assignment, providing a concise way to update variables based on a condition.
#### Code Example:
```javascript
let a = true;
let b = false;
a &&= 'Assigned if true';
b ||= 'Assigned if false';
console.log(a); // Output: 'Assigned if true'
console.log(b); // Output: 'Assigned if false'
```
Use logical assignment operators to simplify conditional assignments, making your code more readable and concise.
### 7. Labels for Loop and Block Statements
Labels are identifiers followed by a colon, used to label loops or blocks for reference in break or continue statements.
#### Code Example:
```javascript
outerLoop: for (let i = 0; i < 3; i++) {
console.log(`Outer loop iteration ${i}`);
for (let j = 0; j < 3; j++) {
if (j === 1) {
break outerLoop; // Break out of the outer loop
}
console.log(` Inner loop iteration ${j}`);
}
}
// Output:
// Outer loop iteration 0
// Inner loop iteration 0
```
```javascript
labelBlock: {
console.log('This will be printed');
if (true) {
break labelBlock; // Exit the block
}
console.log('This will not be printed');
}
// Output:
// This will be printed
```
Use labels to control complex loop behavior, making it easier to manage nested loops and improve code clarity.
### 8. Tagged Template Literals
Tagged template literals allow you to parse template literals with a function, enabling custom processing of string literals.
#### Code Example 1:
```javascript
function logWithTimestamp(strings, ...values) {
const timestamp = new Date().toISOString();
return (
`[${timestamp}] ` +
strings.reduce((result, str, i) => {
return result + str + (values[i] || '');
})
);
}
const user = 'JohnDoe';
const action = 'logged in';
console.log(logWithTimestamp`User ${user} has ${action}.`);
// Outputs: [2024-07-10T12:34:56.789Z] User JohnDoe has logged in.
```
#### Code Example 2:
```javascript
function validate(strings, ...values) {
values.forEach((value, index) => {
if (typeof value !== 'string') {
throw new Error(`Invalid input at position ${index + 1}: Expected a string`);
}
});
return strings.reduce((result, str, i) => {
return result + str + (values[i] || '');
});
}
try {
const validString = validate`Name: ${'Alice'}, Age: ${25}`;
console.log(validString); // This will throw an error
} catch (error) {
console.error(error.message); // Outputs: Invalid input at position 2: Expected a string
}
```
Use tagged template literals for advanced string processing, such as creating safe HTML templates or localizing strings.
### 9. Bitwise Operators for Quick Math
Bitwise operators in JavaScript perform operations on binary representations of numbers. They are often used for low-level programming tasks, but they can also be handy for quick mathematical operations.
#### List of Bitwise Operators
- `&` (AND)
- `|` (OR)
- `^` (XOR)
- `~` (NOT)
- `<<` (Left shift)
- `>>` (Right shift)
- `>>>` (Unsigned right shift)
#### Code Example 1:
You can use the AND operator to check if a number is even or odd.
```javascript
const isEven = (num) => (num & 1) === 0;
const isOdd = (num) => (num & 1) === 1;
console.log(isEven(4)); // Outputs: true
console.log(isOdd(5)); // Outputs: true
```
#### Code Example 2:
You can use left shift (<<) and right shift (>>) operators to multiply and divide by powers of 2, respectively.
```javascript
const multiplyByTwo = (num) => num << 1;
const divideByTwo = (num) => num >> 1;
console.log(multiplyByTwo(5)); // Outputs: 10
console.log(divideByTwo(10)); // Outputs: 5
```
#### Code Example 3:
You can check if a number is a power of 2 using the AND operator.
```javascript
const isPowerOfTwo = (num) => num > 0 && (num & (num - 1)) === 0;
console.log(isPowerOfTwo(16)); // Outputs: true
console.log(isPowerOfTwo(18)); // Outputs: false
```
Use bitwise operators for performance-critical applications where low-level binary manipulation is required, or for quick math operations.
### 10. `in` Operator for Property Checking
The `in` operator checks if a property exists in an object.
#### Code Example:
```javascript
const obj = { name: 'Alice', age: 25 };
console.log('name' in obj); // Output: true
console.log('height' in obj); // Output: false
```
Use the `in` operator to verify the existence of properties in objects, ensuring that your code handles objects with missing properties gracefully.
### 11. `debugger` Statement
The `debugger` statement invokes any available debugging functionality, such as setting a breakpoint in the code.
#### Code Example:
```javascript
function checkValue(value) {
debugger; // Execution will pause here if a debugger is available
return value > 10;
}
checkValue(15);
```
Use the `debugger` statement during development to pause execution and inspect code behavior, helping you identify and fix bugs more efficiently.
### 12. Chained Assignment
Chained assignment allows you to assign a single value to multiple variables in a single statement.
#### Code Example:
```javascript
let a, b, c;
a = b = c = 10;
console.log(a, b, c); // Output: 10 10 10
```
Use chained assignment for initializing multiple variables with the same value, reducing code redundancy.
### 13. Dynamic Function Names
Dynamic function names allow you to define functions with names computed at runtime.
#### Code Example:
```javascript
const funcName = 'dynamicFunction';
const obj = {
[funcName]() {
return 'This is a dynamic function';
}
};
console.log(obj.dynamicFunction()); // Output: 'This is a dynamic function'
```
Use dynamic function names to create functions with names based on runtime data, enhancing code flexibility and reusability.
### 14. Get Function Arguments
The `arguments` object is an array-like object that contains the arguments passed to a function.
#### Code Example:
```javascript
function sum() {
let total = 0;
for (let i = 0; i < arguments.length; i++) {
total += arguments[i];
}
return total;
}
console.log(sum(1, 2, 3)); // Outputs: 6
```
Use the `arguments` object to access all arguments passed to a function, useful for functions with variable-length arguments.
### 15. Unary `+` Operator
The unary operator (`+`) converts its operand into a number.
#### Code Example:
```javascript
console.log(+'abc'); // Outputs: NaN
console.log(+'123'); // Outputs: 123
console.log(+'45.67'); // Outputs: 45.67 (converted to a number)
console.log(+true); // Outputs: 1
console.log(+false); // Outputs: 0
console.log(+null); // Outputs: 0
console.log(+undefined); // Outputs: NaN
```
Use the unary operator for quick type conversion, especially when working with user input or data from external sources.
### 16. Exponentiation `**` Operator
The exponentiation operator (`**`) performs exponentiation (power) of its operands.
#### Code Example:
```javascript
const base = 2;
const exponent = 3;
const result = base ** exponent;
console.log(result); // Output: 8
```
Use the exponentiation operator for concise and readable mathematical expressions involving powers, such as in scientific or financial calculations.
### 17. Function Properties
Functions in JavaScript are objects and can have properties.
#### Code Example 1:
```javascript
function myFunction() {}
myFunction.description = 'This is a function with a property';
console.log(myFunction.description); // Output: 'This is a function with a property'
```
#### Code Example 2:
```javascript
function trackCount() {
if (!trackCount.count) {
trackCount.count = 0;
}
trackCount.count++;
console.log(`Function called ${trackCount.count} times.`);
}
trackCount(); // Outputs: Function called 1 times.
trackCount(); // Outputs: Function called 2 times.
trackCount(); // Outputs: Function called 3 times.
```
Use function properties to store metadata or configuration related to the function, enhancing the flexibility and organization of your code.
### 18. Object Getters & Setters
Getters and setters are methods that get or set the value of an object property.
#### Code Example:
```javascript
const obj = {
firstName: 'John',
lastName: 'Doe',
_age: 0, // Conventionally use an underscore for the backing property
get fullName() {
return `${this.firstName} ${this.lastName}`;
},
set age(newAge) {
if (newAge >= 0 && newAge <= 120) {
this._age = newAge;
} else {
console.log('Invalid age assignment');
}
},
get age() {
return this._age;
}
};
console.log(obj.fullName); // Outputs: 'John Doe'
obj.age = 30; // Setting the age using the setter
console.log(obj.age); // Outputs: 30
obj.age = 150; // Attempting to set an invalid age
// Outputs: 'Invalid age assignment'
console.log(obj.age); // Still Outputs: 30 (previous valid value remains)
```
Use getters and setters to encapsulate the internal state of an object, providing a controlled way to access and modify properties.
### 19. `!!` Bang Bang Operator
The `!!` (double negation) operator converts a value to its boolean equivalent.
#### Code Example:
```javascript
const value = 'abc';
const value1 = 42;
const value2 = '';
const value3 = null;
const value4 = undefined;
const value5 = 0;
console.log(!!value); // Outputs: true (truthy value)
console.log(!!value1); // Outputs: true (truthy value)
console.log(!!value2); // Outputs: false (falsy value)
console.log(!!value3); // Outputs: false (falsy value)
console.log(!!value4); // Outputs: false (falsy value)
console.log(!!value5); // Outputs: false (falsy value)
```
Use the `!!` operator to quickly convert values to booleans, useful in conditional expressions.
### 20. Map and Set Objects
`Map` and `Set` are collections with unique features. `Map` holds key-value pairs, and `Set` holds unique values.
#### Code Example 1:
```javascript
// Creating a Map
const myMap = new Map();
// Setting key-value pairs
myMap.set('key1', 'value1');
myMap.set(1, 'value2');
myMap.set({}, 'value3');
// Getting values from a Map
console.log(myMap.get('key1')); // Outputs: 'value1'
console.log(myMap.get(1)); // Outputs: 'value2'
console.log(myMap.get({})); // Outputs: undefined (different object reference)
```
#### Code Example 2:
```javascript
// Creating a Set
const mySet = new Set();
// Adding values to a Set
mySet.add('apple');
mySet.add('banana');
mySet.add('apple'); // Duplicate value, ignored in a Set
// Checking size and values
console.log(mySet.size); // Outputs: 2 (only unique values)
console.log(mySet.has('banana')); // Outputs: true
// Iterating over a Set
mySet.forEach((value) => {
console.log(value);
});
// Outputs:
// 'apple'
// 'banana'
```
Use `Map` for collections of key-value pairs with any data type as keys, and `Set` for collections of unique values, providing efficient ways to manage data.
## Conclusion
By leveraging these lesser-known JavaScript features, you can write more efficient, readable, and robust code. Start integrating these techniques into your projects to take your JavaScript skills to the next level.
We hope this guide has provided you with valuable insights and practical examples to help you leverage these hidden JavaScript features. Don't hesitate to experiment with them and see how they can fit into your coding practices.

Front End News is back after a long pause, and the topics are extensive. We'll start with the updated 2024 edition of the Front End Developer/Engineer Handbook by Cody Lindley and the Front End Masters. Next, we have the long-awaited results of the State of HTML and State of JavaScrip 2023 surveys.
There is a lot of news about the Web Platform and mainstream browsers. Google I/O and WWDC were used to announce many upcoming changes. A new player enters the game - Arc, from the Browser Company, is now available on Windows. We have releases from Chrome (125/126), Firefox (126/127), Polypane (19/20), Vivaldi (6.7/6.8), and WebKit/Safari (17.5/18-beta).
Developers have plenty of new shiny versions of their favorite tools of the trade. Angular 18, Electron 30-31, Nuxt 3.12, TypeScript 5.5 RC, and multiple releases from Astro, Deno, ESLint, or Node are just some of the recent releases. There is even a jQuery UI update - are you still using it?
As usual, we wrap up with Front End Resources. This issue includes a large set of icons, shapes, generators, tools, and utilities, all free for you to use.

## The Front End Developer/Engineer Handbook 2024
Cody Lindley and the Front End Masters are back with a new Front End Developer Handbook edition. It is the long-expected continuation of a series that took a break in 2019. The industry has experienced many changes over the past five years, and the Handbook is back with fresh advice to help developers master their careers.

## State of HTML 2023 Results
State of HTML 2023 is the first attempt at surveying what the community thinks about the current state of HTML. It covered not only the HTML elements, but accessibility, web components, and a lot more. There were over 20000 people and a lot of answers to process. With a new way of displaying the results, we can understand why it took nearly half of 2024 to see them.
Forms and inputs are still major pain points; people want native elements for common interface elements like tabs, and web components are becoming increasingly popular. However, many new features are held back by the lack of wide browser support. You can find more details on the survey results pages.
- [State of HTML 2023](https://2023.stateofhtml.com/en-US/)
- [Discover the State of HTML 2023 Survey Results](https://dev.to/sachagreif/discover-the-state-of-html-2023-survey-results-n10)
***
## State of JavaScript 2023 Results
The State of JavaScript is the second survey we discuss in this issue. It had the same ambitious reach as its State of HTML counterpart, with many freeform answer options. Over 23500 developers took part in this edition, and here are some of their choices.
React leads the pack for another year, while Vue climbs to second place, pushing Angular down to third place. Next.js increases its lead over the other meta-frameworks, while Electron and React Native are struggling fiercely for the top spot among mobile and desktop tool kits. Over 70% of the respondents write mostly TypeScript, while less than 10% write only pure JavaScript.

### Arc
Arc is a new(ish) browser from the Browser Company. It has been making waves on macOS and iOS over the last couple of years, and it just arrived on Windows, where Chrome reigns supreme. This launch also propelled Swift (a programming language created by Apple) to become a viable alternative for building Windows applications.
Arc aims to be more than a browser, instead becoming "the operating system for the Internet." The release received a warm reception and good reviews from platforms like The Verge or Tech Radar, which I'm adding below.

- Tech Radar: [The Arc browser just launched and yes, it really is that good](https://www.techradar.com/computing/browsers/the-arc-browser-just-launched-and-yes-it-really-is-that-good)
### Chrome
Chrome released two versions since the last issue of this newsletter. Chrome 125 brings CSS Anchor Positioning, the Compute Pressure API (measuring the CPU load), and the option to use the Storage Access API for non-cookie storage.
- [New in Chrome 125](https://developer.chrome.com/blog/new-in-chrome-125)
- [What's new in DevTools, Chrome 125](https://developer.chrome.com/blog/new-in-devtools-125)
Chrome 126 allows cross-document transitions for same-origin navigation; the CloseWatcher API is back for `dialog` and `popover` elements; the DevTools are now running Lighthouse 12.0.0, and more.

- [Firefox 127 for developers](https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/127)
### Polypane
Polypane has also grown two full versions since the last issue. Polypane 19 brings various workflow improvements, such as automatic dark mode emulation, Chromium 124, and more.
- [Polypane 19: Workflow improvements](https://polypane.app/blog/polypane-19-workflow-improvements/)
Polypane 20 brings Chromium 126, various performance tweaks, better screenshot functionality, and more.
- [Polypane 20: Browser features and performance](https://polypane.app/blog/polypane-20-browser-features-and-performance/)
### Vivaldi
Vivaldi also had a double release across all three platforms: desktop, iOS, and Android. Vivaldi 6.7 brings better memory performance on desktops, support for multiple windows on iPads, and many quality-of-life improvements on Android devices.
- [Vivaldi on iOS adds multiple windows support to iPad, improves Notes, Bookmarks, and Dark Mode](https://vivaldi.com/blog/vivaldi-on-ios-6-7/)

- [Improved browser features for desktop and Vivaldi Mail 2.0 amped up with new functionalities](https://vivaldi.com/blog/desktop/desktop-releases/vivaldi-on-desktop-6-8/)
### WebKit
The WebKit team is determined to prove that Safari is NOT the new Internet Explorer. This means they worked hard to keep their browser on par (or even ahead) of the other browsers. Safari 17.5 brings new CSS features (`text-wrap: balance`, the `light-dark()` color function, and `@starting-style`) and many fixes and quality-of-life improvements.
- [WebKit Features in Safari 17.5](https://webkit.org/blog/15383/webkit-features-in-safari-17-5/)
- [Safari 17.5 Release Notes](https://developer.apple.com/documentation/safari-release-notes/safari-17_5-release-notes)
Apple had its own event - WWDC24 - and used the occasion to highlight the upcoming features in Safari 18 Beta. As release notes are never too user-friendly, I'm linking an article by Stefan Judis, where he discusses all the new stuff, providing extra info about overall browser coverage, Baseline support, and any other relevant data.
- [News from WWDC24: WebKit in Safari 18 beta](https://webkit.org/blog/15443/news-from-wwdc24-webkit-in-safari-18-beta/)

I didn't have much experience to begin with, and never fully finished my degree. My dad always wanted me to get into the field to take over his companies. Things didn't go as planned.
I'm trying to get pointers on where to begin. I have chosen MANY fields I feel like I would be good at. I found some courses, training programs, etc but idk where to actually begin. It's still overwhelming.
I found this community because I found a post breaking stuff down, and then I lost it.
If you could point me into some posts I should read, links, whatever it would be greatly appreciated. If I need to post the fields I'm interested in, I can do that too. | taylor_laydon_77 | |
1,919,891 | Metadata to actionable insights in Grafana: How to view Parseable metrics | Parseable deployments in the wild are handling larger and larger volumes of logs, so we needed a way... | 0 | 2024-07-11T15:55:59 | https://dev.to/parseable/metadata-to-actionable-insights-in-grafana-how-to-view-parseable-metrics-3oa4 | Parseable deployments in the wild are handling larger and larger volumes of logs, so we needed a way to enable users to monitor their Parseable instances.
Typically this would mean setting up Prometheus to capture Parseable ingest and query node metrics and visualize those metrics on a Grafana dashboard. We added [Prometheus metrics support in Parseable](https://www.parseable.com/docs/integrations/prometheus-metrics-and-configuration) to enable this use case.
But we wanted a simpler, self-contained approach that allows users to monitor their Parseable instances without needing to set up Prometheus.
This led us to figuring out a way to store Parseable server's internal metrics in a special log stream called `pmeta`.
This stream keeps track of important information about all of the ingestors in the cluster. This includes information like the URL of the ingestor, commit id of that ingestor, number of events processed by the ingestor, and staging file location and size.
This is a sample event in the `pmeta` stream.
```
{
"address": "http://ec2-3-136-154-35.us-east-2.compute.amazonaws.com:443/",
"cache": "Disabled",
"commit": "d6116e8",

"event_type": "cluster-metrics",
"p_metadata": "",
"p_tags": "",
"p_timestamp": "2024-07-02T09:49:05.540",

"parseable_storage_size_staging": 0,
"process_resident_memory_bytes": 113250304,
"staging": "/home/ubuntu/parseable/staging"
}
```
Let's show you how to visualize this data in a Grafana dashboard.
We'll start by setting up Parseable to collect this `pmeta` data.
## Getting Started with Parseable
Parseable is a cloud-native log management solution that efficiently handles large-scale log data. By integrating Parseable with your infrastructure, you can streamline log ingestion, storage, and querying, making it an essential tool for observability and monitoring.
You can [choose the right installation process](https://www.parseable.com/docs/installation) for you.
To quickly install Parseable using Docker, open the terminal and type the command:
```
docker run -p 8000:8000 \
-v /tmp/parseable/data:/parseable/data \

```
You can verify the installation by accessing the Parseable UI by navigating to http://localhost:9000 in your web browser. Log in using the default credentials (admin/admin) and explore the dashboard to ensure everything is set up correctly.
Finally, we need to create a log stream before we can send events. A log stream is like a project that will essentially store all your ingested logs. For this tutorial, we'll have a log stream named `pmeta`. To create a log stream, log in to your Parseable instance, and you'll find a button on the right-hand top side.
Note that:
- `pmeta` is automatically created and populated in a Parseable cluster (high availability setup)
- `pmeta` is not created in a single node setup
- if you're not interested in this data, you can set the retention to 1 day for the `pmeta` stream to avoid storing this data
Read more about the `pmeta` stream in the [Parseable documentation](https://www.parseable.com/docs/concepts/concepts#internal-log-stream).
## Instal Grafana and the Parseable plugin
Grafana helps you collect, correlate, and visualize data with beautiful dashboards. We'll connect the parseable instance with Grafana via the [Parseable Grafana datasource](https://github.com/parseablehq/parseable-datasource). This plugin allows you to query Parseable data using SQL and visualize it in Grafana.
If you want to self-host Grafana, you can host it on a dedicated cloud instance or locally, depending on your requirements. Follow the official Grafana [installation guide](https://grafana.com/docs/grafana/latest/setup-grafana/installation/) for more information.
Once the Grafana instance is setup, let's quickly install the Parseable plugin and connect our Parseable instance to Grafana.
Login to your Grafana instance and navigate to the administration setting on the left-hand side menu.
Click on Plugin and Data Option
Open the Plugins page and search for `Parseable`
Install the plugin and then click on `Add New Datasource`
From the datasource page, fill in the following details:
In the URL field, type the URL of your Parseable query instance. For example, `https://demo.parseable.com:443`.
Under the Auth Section, switch to the `Basic Auth` setting.
In the `Basic Auth Details` section, enter your Parseable username and password.
Finally, click on `Save & Test` to verify the connection.
## Setting up the Grafana dashboard
We'll now use the Parseable Data Source to query data from the Parseable Meta Stream (`pmeta`).
Navigate to the Dashboard section and click on `New` and select `Import Dashboard`.
Enter the Dashboard ID as `21472` and click on load.
Ensure the data source to Parseable-DataSource by selecting from the dropdown menu.
Once done, click on `import`. It should take a few seconds to load, and then it will create the dashboard.
We query data from Parseable using SQL. To learn more about querying data in Parseable, you can refer to [our documentation](https://www.parseable.com/docs/concepts/query).
## Summary
Now, you've learned how to create a Grafana dashboard using Parseable's `pmeta` stream.
This dashboard provides crucial insights into your Parseable instance's performance, and we encourage you to customize this dashboard further to fit your specific needs.

Even though the docker hub provides a huge collection of images for a variety of uses there are some cases where we would want to create something complex from SCRATCH !!!!.
That's where the Scratch base image from Docker comes in handy. There are several ways to generate base images, such as using an already-existing Linux machine or a running container, but for now, let's utilize a Docker [**_scratch image_**](https://hub.docker.com/_/scratch/).
To use scratch we just need to add **FROM Scratch** in our Dockerfiles. Yes, _that's it!_ above this, you can add anything to configure your base image, Build it and it's ready to use.
<br>
For Example, let's create one. Create and Add the following to the Dockerfile.
```
FROM scratch
ADD hellofromdocker /
CMD ["/hellofromdocker"]
```
That's it here [**_hellofromdocker_**](https://github.com/Deepcodr/DOCKER/blob/main/scratch-base-image/hellofromdocker) is a static executable that does not have any runtime or linked dependencies. Since the scratch image only contains the bare minimum of runtime and settings needed to create base images, using other executables or apps may not work.
Once the Dockerfile is done. build an image using docker.
`docker build -t helloscratchimg .`
Spin up a container from a newly created base image and get hello from Docker! 🤩
