## Introduction
How to be successful? You need to constantly evolve to stay competitive. One significant shift many organizations undertake is migrating data from legacy systems to modern platforms like Salesforce. This process, while challenging, offers numerous benefits such as improved efficiency, better data management, and enhanced customer relationship management.
Migrating data from legacy systems to [Salesforce](https://www.salesforce.com/eu/) is not just a technical task but a strategic move that can redefine how a business operates. Legacy systems, often developed decades ago, may no longer meet the demands of modern business processes. They can be rigid, hard to integrate with newer technologies, and lack the flexibility needed for today’s data-driven decision-making.

Salesforce, on the other hand, offers a robust platform designed to handle contemporary business requirements. It supports advanced features like [Salesforce CPQ](https://www.salesforce.com/eu/products/cpq/resources/what-is-salesforce-cpq/) (Configure, Price, Quote), seamless integration capabilities, and a comprehensive CRM system that is more adaptable to the evolving needs of businesses. However, the migration process requires careful planning and execution to ensure that data integrity is maintained and business continuity is not disrupted.
For example, the [Financial Services Cloud implementation](https://www.sfapps.info/salesforce-fsc-implementation-guide/) provides a tailored solution for financial institutions, enabling them to manage customer relationships more effectively. Similarly, the [Salesforce to NetSuite integration](https://www.sfapps.info/netsuite-salesforce-migration-in-retail/), showcases how businesses can achieve a unified view of their operations, enhancing decision-making processes.
In addition, Salesforce integration with legacy systems allows businesses to preserve the value of their existing IT investments while leveraging the advanced capabilities of Salesforce. This integration can be particularly beneficial for companies that have extensive legacy API Salesforce implementations or those dealing with Salesforce legacy CRM systems. The migration of legacy applications to the Salesforce platform ensures that businesses can modernize their operations without losing critical historical data.
## Preparation and Planning
The success of data migration from legacy systems to Salesforce hinges on thorough preparation and meticulous planning. This stage sets the foundation for a smooth and effective transition, ensuring that all aspects of the migration are carefully considered and addressed. Here’s how to approach the preparation and planning phase:
### 1. Assessing Current Systems and Data
Before starting the migration, it’s crucial to perform a comprehensive assessment of the current legacy systems. This involves:
**Inventorying Data Sources:** Identify all the data sources and systems involved. This includes CRM systems, databases, ERP systems, and any other repositories where relevant data is stored.
**Data Quality Analysis:** Evaluate the quality of data in the legacy systems. Identify duplicates, inconsistencies, and obsolete data that need to be cleaned up before migration.
**Mapping Data Fields:** Understand how data fields in legacy systems correspond to those in Salesforce. This step is vital for ensuring accurate data mapping and migration.
### 2. Defining Objectives and Scope
Clearly defining the objectives and scope of the migration project helps in setting realistic expectations and goals. Key considerations include:
**Business Goals:** Determine the business goals driving the migration. For instance, are you aiming to improve customer relationship management, enhance reporting capabilities, or streamline business processes?
**Scope of Migration:** Decide the scope of the migration. Will you migrate all historical data or only data from a specific period? Will you include all data entities or only selected ones?
### 3. Creating a Migration Plan
A detailed migration plan acts as a roadmap for the entire process. The plan should include:
**Timeline and Milestones:** Establish a realistic timeline with key milestones. This helps in tracking progress and ensuring timely completion of the migration.
**Resource Allocation:** Identify the team members and resources required for the migration. This includes IT staff, data analysts, and Salesforce experts.
**Risk Management:** Anticipate potential risks and challenges that may arise during the migration. Develop contingency plans to address these risks.
### 4. Choosing the Right Tools
Selecting the appropriate tools and technologies is crucial for efficient data migration. Consider the following:
**Data Migration Tools:** Choose tools that facilitate seamless data migration from legacy systems to Salesforce. These tools should support data mapping, transformation, and validation.
**Integration Solutions:** For Salesforce integration with legacy systems, select integration solutions that ensure data consistency and synchronization between systems.
### 5. Testing and Validation
Testing is a critical component of the preparation phase. Ensure thorough testing of the migration process:
**Pilot Migration:** Conduct a pilot migration with a subset of data to identify potential issues and validate the migration process.
**Data Validation:** Perform rigorous data validation to ensure data accuracy and integrity. This includes verifying that all data has been correctly migrated and mapped.
### 6. Training and Change Management
Preparing your team for the new system is essential for a smooth transition. Focus on:
**Training Programs:** Develop training programs to educate users on how to use Salesforce effectively. This includes training on new features and workflows.
**Change Management:** Implement change management strategies to address resistance and ensure a smooth transition for all stakeholders.
By following these steps, you can lay a strong foundation for a successful data migration from legacy systems to Salesforce. Proper preparation and planning not only mitigate risks but also ensure that the migration aligns with your business objectives and enhances overall efficiency.
## Execution and Migration
Once the preparation and planning phases are complete, it’s time to move on to the actual execution of the data migration. This phase involves the technical process of moving data from legacy systems to Salesforce, ensuring data integrity, and minimizing downtime. Here’s a step-by-step guide to executing the migration effectively:
### 1. Data Extraction
The first step in the execution phase is to extract data from the legacy systems. This involves:
**Connecting to Data Sources:** Use data migration tools to connect to all relevant legacy systems. Ensure that you have the necessary permissions and access rights to extract data.
**Extracting Data:** Extract data in a structured format. This typically involves exporting data into CSV files or using APIs to pull data from the legacy systems.
### 2. Data Transformation
Once data is extracted, it needs to be transformed to match the format and structure required by Salesforce. This step includes:
**Data Mapping:** Map the fields from the legacy system to the corresponding fields in Salesforce. This ensures that data is correctly aligned and placed in the right context.
**Data Cleansing:** Clean the data to remove duplicates, correct errors, and standardize formats. This step is crucial to ensure that only high-quality data is migrated to Salesforce.
**Data Enrichment:** Enhance the data by adding any missing information or updating outdated records to ensure it is as accurate and comprehensive as possible.
### 3. Data Loading
With data extracted and transformed, the next step is to load the data into Salesforce. This involves:
**Batch Loading:** Load data in batches to manage the volume and complexity of the migration. This helps in monitoring progress and addressing issues as they arise.
**Using Data Loader:** Utilize Salesforce Data Loader or other ETL (Extract, Transform, Load) tools to import data into Salesforce. These tools provide a user-friendly interface and robust capabilities for data import.
**Error Handling:** Monitor the loading process for errors. If any errors occur, address them promptly to ensure that the data is loaded correctly.
### 4. Validation and Testing
After loading the data, it’s essential to validate and test to ensure the migration was successful. This includes:
**Data Verification:** Verify that all data has been accurately migrated and is available in Salesforce. Check for completeness and consistency.
**Functional Testing:** Conduct functional tests to ensure that all Salesforce features and integrations are working as expected with the newly migrated data.
**User Acceptance Testing (UAT):** Engage end-users to test the system and provide feedback. This helps in identifying any usability issues or data discrepancies that need to be addressed.
### 5. Go-Live and Monitoring
With data loaded and validated, you can proceed to go live. This involves:
**Switching Over:** Transition from the legacy system to Salesforce. Ensure minimal disruption to business operations during the switchover.
**Monitoring Performance:** Continuously monitor the performance of Salesforce after going live. Track key metrics and address any issues promptly to ensure smooth operation.
### 6. Post-Migration Activities
Post-migration activities are crucial to ensure long-term success and stability. This includes:
**Data Backup:** Regularly back up data to prevent loss and ensure recovery in case of any issues.
**Ongoing Support:** Provide ongoing support to users to address any questions or issues they may encounter. This helps in the smooth adoption of the new system.
**Optimization:** Continuously optimize Salesforce to improve performance and add new features as needed. This ensures that the system remains aligned with business needs and goals.
By following these steps, you can ensure a successful execution of data migration from legacy systems to Salesforce. Proper execution and migration not only ensure data integrity but also enable businesses to leverage the full potential of Salesforce for improved efficiency and decision-making.

Here are key steps and best practices to consider in this phase:
### 1. Data Validation and Cleaning
Even after careful migration, some data issues might persist. It’s crucial to perform continuous validation and cleaning:

**Integration Monitoring:** Monitor integrations to ensure they are functioning correctly and data is being synchronized as expected. Address any integration issues promptly to avoid data discrepancies.
### 5. Continuous Improvement
Adopt a mindset of continuous improvement to keep Salesforce aligned with evolving business needs:
**Regular Reviews:** Conduct regular reviews of Salesforce usage and performance. Identify areas for improvement and implement changes to enhance efficiency and effectiveness.
**User Engagement:** Engage users in the process of continuous improvement. Encourage them to share their insights and suggestions for enhancing the system.
### 6. Security and Compliance
Ensure that your Salesforce implementation remains secure and compliant with relevant regulations:
**Data Security Measures:** Implement robust data security measures such as encryption, access controls, and regular security audits.
**Compliance Monitoring:** Regularly monitor compliance with industry regulations and standards. Ensure that your Salesforce implementation adheres to data protection and privacy laws.
By focusing on these post-migration optimization practices, businesses can ensure that their Salesforce implementation continues to deliver value, remains secure, and evolves with changing business requirements.

1,877,856 | Weekly Crypto Updates: Google and Magic Leap Collaborate, CertiK Introduces New Initiative, Binance User Loses $1 Million | Meta vice president Yann LeCun and Tesla founder Elon Musk started the most popular nerd battle on... | 0 | 2024-06-05T10:09:21 | https://36crypto.com/weekly-crypto-updates-google-and-magic-leap-collaborate-certik-introduces-new-initiative-chatgpt-for-universities/ | cryptocurrency, news |
Meta vice president Yann LeCun and Tesla founder Elon Musk [started](https://cointelegraph.com/news/meta-ai-artificial-intelligence-chief-slams-elon-musk-hype-conspiracy-theories) the most popular nerd battle on social media in 2024. During the week, both executives argued on the X social network and actively criticized each other. In the meantime, many other interesting events took place, which we will discuss today.
**Google and Magic Leap Collaborate to Expand the Potential of AR Technologies**
One of the leaders in the augmented reality industry, Magic Leap, has announced a partnership with Google to expand the potential of the technology. According to the [statement](https://www.magicleap.com/newsroom/magic-leap-and-google-partnership), the cooperation aims to launch unique product offerings and further expand the relationship between the companies.
Shahram Izadi, vice president and general manager of AR/XR at Google, expressed his excitement about the collaboration, commenting on it: _“We look forward to bringing together Magic Leap’s leadership in optics and manufacturing with our technologies to bring a wider range of immersive experiences to market. By combining efforts, we can foster the future of the XR ecosystem with unique and innovative product offerings.”_
Julie Larson-Green, Magic Leap’s CTO, described the partnership as a move that will accelerate the transformation of augmented reality (AR) by leveraging the expertise of the two companies. She also noted that she is looking forward to “expanding the potential of extended reality (XR) — connecting the physical world with valuable, contextually relevant solutions.”
The publication does not describe any specific products or potential services, but it is possible that this could mean the emergence of a new headset suitable for AR/XR, and thus much-needed competition for the current market leaders, Meta and Apple.
**ChatGPT for Universities**
AI company OpenAI has [launched](https://openai.com/index/introducing-chatgpt-edu/) several initiatives aimed at expanding ChatGPT services to universities and non-profit organizations. The first of the new directions is ChatGPT Edu, a version of the large-scale AI language model designed specifically for use by students, teachers, researchers, etc. According to the company, the new offering “includes enterprise-level security and management tools and is available for educational institutions.”
OpenAI also outlined specific use cases of chatbots at the university level. Among the institutions that used the service were Oxford, Wharton, the University of Texas at Austin, Arizona State University, and Columbia University.
For example, researchers at Columbia University are using ChatGPT to develop strategies aimed at reducing overdose deaths. At the same time, an assistant professor at Arizona State University has developed the GPT Buddy program, which allows German language students to practice their language skills conversationally in their free time.
Kyle Bowen, Associate Director of Information Technology at Arizona State University, praised the ChatGPT Edu initiative: _“Integrating OpenAI’s technology into our educational and operational frameworks accelerates transformation at ASU. We’re collaborating across our community to harness these tools, extending our learnings as a scalable model for other institutions.”_
**Binance User Loses $1 Million Worth of Cryptocurrency**
A Chinese trader lost $1 million to a hacker scam using a Google Chrome adware plugin called Aggr. The plugin steals cookies from users, which are then used by hackers to bypass passwords, verify two-factor authentication (2FA), and log into the victim’s Binance account.
A Nakamao user [shared](https://x.com/CryptoNakamao/status/1797519128632381847) the details of this incident on the social network X. On May 24, the trader noticed unusual trading activity in his account. The crypto hacker was making large trades on the USDT pair with high liquidity and placing limited orders for sale at inflated prices in pairs with limited liquidity. In this way, the hacker made significant profits without triggering any alerts from Binance. Additionally, he added that the exchange’s delay in contacting other platforms to freeze the hacker’s funds led to a loss of opportunities to recover the stolen assets.
Despite Nakamao’s immediate attempts to contact the exchange’s support team, the attacker continued to manage the victim’s account, eventually successfully withdrawing all funds. The trader expressed frustration with Binance’s slow response and lack of effective risk control, which left the hacker’s apparent arbitrage operations unchecked.
Nakamao also noted that Binance had been aware of the malicious plugin and the hacker’s activities for some time. However, the exchange did not take immediate action to warn users or stop the promotion of Aggr.
**Bybit Restructures Executive Team after Airdrop Fiasco**
A few days ago, cryptocurrency exchange Bybit restructured its team after a mistaken airdrop distribution of more than $26 million. Reports of the management changes [appeared](https://t.me/wublockchainenglish/13213) on May 31.
A representative of the exchange [told](https://cointelegraph.com/news/bybit-restructures-executive-team-airdrop-fiasco) Cointelegraph that the company regularly updates its business structure: “Together with the team, we made a joint commitment to placing the right people in the right roles. […] This improvement led to some leadership role changes, which we believe are essential. […] The affected team members are not leaving the company but moved to take up other internal roles.”
The changes came after the failed airdrop of the Notcoin (NOT) token. In a statement, Bybit explained that the distribution of tokens was delayed due to system maintenance and an unusually high volume of transactions.
The delay in token distribution resulted in a lower trading price for those who received their tokens later. According to the exchange, the balance problem affected 320,000 users. In response to the incident, Bybit announced a $26 million compensation plan on May 17.
_“Total around $26M compensation will be processed within 3 working days, and emails will be sent to you. Again, sorry for the problem caused, we will do a deep dive internally to make sure it never happens again,”_ [wrote](https://x.com/benbybit/status/1791080850945392952) Bybit’s CEO Ben Zhou.
Launched in January 2024, Notcoin is a free-to-play money-making game on Telegram where users can earn rewards in the eponymous Notcoin token by simply tapping on coin icons.

Today I would like to do some advertising. Do you know
## [Flems.io](https://github.com/porsager/flems.io) ?
Flems.io is a simple, but very smart prototyping platform ideal for testing oder demonstration of HTML/CSS/Javascript or even Typescript. Ok, simple might not be the right wording, it´s just super simple to use. Under the hood, it provides quite a lot:
> Flems supports TypeScript, LiveScript and Babel (standalone) compilation too. You can add CSS & JS dependencies by specifying a full URL pointing to the desired file, or by giving a reference to an NPM package (and optional path) - these will be taken from unpkg.com (See the [documentation](https://github.com/porsager/flems.io) for more info.)
Flems.io is similar to online editors like [CodePen](https://codepen.io/) or [JSFiddle](https://jsfiddle.net/), but has one unique selling point. You do not need an account or any external memory: *Flems.io stores all data in the URL!*. This is ideal for short tests and demos provided on dev.to or other online media.
Flems-URL´s can get quite long as they store all information + page settings, so you might push the limits using windows desktop links, which are limited to 256 characters. But using Flems-URL´s on online platforms like dev.to is usually not a problem. Unlike other platforms Flems.io does not require any initialization, so it is up and running in no time. It´s best usable for short demos or just for a quick test of some lines of code.
Here is an example, i alredy provided [here](https://dev.to/efpage/build-a-comfortable-and-blazing-fast-image-viewer-in-just-10-lines-of-javascript-code-5gad)

We learn a new concept, familiarize ourselves with new... | 0 | 2024-06-05T10:06:10 | https://dev.to/hijohnmark/foreach-for-dummies-362i | It's happened to all beginner developers. We learn a new concept, familiarize ourselves with new functionality in a limited, controlled context and then—much to our frustration—find that in the real world, its application is more nuanced and complex than we anticipated. For someone like me who tends to lean on intuition, this can be incredibly frustrating. Intuition is a double-edged sword when it comes to learning code.
While my hunches are often right, they are just as easily proven wrong. My preconceived notion of what my code might do is often upended by the smallest detail that my intuition deemed irrelevant. And one great example of this is my recent experience with `forEach()`. First, let's review how it works:
## `forEach()` Overview
`forEach()` is an array iterator, one of six available JavaScript methods for array iteration including `map()`, `filter()`, `reduce()`, the `for` loop, and the `for...of` loop.
`forEach()`, simply put, allows you to iterate through each element of an array and perform an action on that element in the form of a function. Here's a simple example of what that looks like in action ([taken from MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach)):
```
const array1 = ['a', 'b', 'c'];
array1.forEach((element) => console.log(element));
// Expected output: "a"
// Expected output: "b"
// Expected output: "c"
```
While `for` loops can accomplish the same purpose, they require [more detailed syntax](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for) to execute.
```
let str = '';
for (let i = 0; i < 9; i++) {
str = str + i;
}
console.log(str);
// Expected output: "012345678"
```
`forEach()` is a simpler way to iterate through items of an array, and is often presented as a parallel method that might be stylistically preferred by certain programmers. However, there are some key differences between a `for` loop and the `forEach()` method that, had I known, would have saved me hours of debugging to no avail.
## How I tripped up on `forEach()`
The task was relatively simple. Given an array of objects, which each object representing a player, and each player object containing keys with stats for that player, I needed to write a function that would iterate through the array, find a player whose name matches the name passed to the function as an argument, and return the number of points that player has scored.
The problem? I had written a function that seemed to be a straightforward solution:
```
function numPointsScored(name){
const teamKeys = Object.keys(gameObject());
forEach(teamKey => {
const players = gameObject()[teamKey].players
const playerNames = Object.keys(players)
for(const playerName of playerNames){
if (playerName === name) {
return players[playerName].points
}
}
})
}
```
However, testing this function with any name would simply return "undefined." I ran debuggers in different parts of the code, checked all the variables, everything seemed to be working correctly and yet still, I couldn't get the number of points that we expected. I ran through this with my instructor and we still couldn't figure out what was happening. After nearly an hour, we decided to walk away from it.
Later on, my instructor found that replacing `forEach()` with a simple `for` loop seemed to solve the problem:
```
function numPointsScored(name){
const teamKeys = Object.keys(gameObject());
for(const teamKey of teamKeys) {
const players = gameObject()[teamKey].players
const playerNames = Object.keys(players)
for(const playerName of playerNames){
if (playerName === name) {
return players[playerName].points
}
}
}
}
```
While finding this solution was a relief, I felt equally exasperated and frustrated. How could the solution be so simple, and WHY was this the case if the functionality of `forEach()` and `for` loops are the same?
The answer is—of course—they aren't!
## Limitations of `forEach()`
There are several limitations to using `forEach()`, and I'd definitely recommend [checking out this blog](https://dev.to/jeffsalive/think-twice-before-you-use-the-foreach-array-method-2i0a) for more great instances of how `forEach()`'s limitations actually make it a method many developers choose to avoid.
The key problem that I encountered with `forEach()` is that **you can't break it** by asking it to perform an action on a specific element and then break the loop. With `forEach()`, committing to iterating over the _entire array_.
There are other issues with this method, such as that it may be less performant than a `for` loop for large arrays, and is less than ideal for asynchronous tasks.
The moral of this story is, when using array methods, make sure you're aware of their limitations. It could save you a huge headache and hours of debugging!

1,877,850 | 17 Tailwind CSS Tips & Tricks You Probably Don't Know | This post contains interactive demos that can only be accessed in the original post at... | 0 | 2024-06-05T10:05:31 | https://devaradise.com/tailwind-css-tips-tricks/ | css, webdev, tailwindcss, beginners | **This post contains interactive demos that can only be accessed in the original post at https://devaradise.com/tailwind-css-tips-tricks/**
Tailwind CSS has been an increasingly popular CSS library today. Although it still not beat Bootstrap's popularity in terms of global usage, Tailwind CSS is the most loved CSS library according to [State of CSS survey 2023](https://2023.stateofcss.com/en-US/css-frameworks/).
More and more developers are adopting Tailwind CSS into their workflow. Some of the latest popular UI component libraries like shadcn ui and Nextui even use Tailwind CSS for their component styling.
Although it's popular and has decent documentation, some developers often skip to specific class documentation without knowing there is cool and useful stuff that is rarely known.
In this post, I'm going to summarize some Tailwind CSS features and utilities you might not know, along with examples. Some of them are even not documented well in the official documentation.
## Styling Based on Other Elements
Tailwind CSS has some features that allow you to style an element based on another element.
### 1. Styling children from parent element (`&_*`)
Generally, you can just put utility classes on any element to style it. But, there is a case where you don't have control over certain elements, like when you are using an external component.
In that case, you can use this class to style the element inside that component. There are 2 ways to style an element from its parent:
- Using `*:{utility-class}` to style direct children which is [documented here](https://tailwindcss.com/docs/hover-focus-and-other-states#styling-direct-children)
- Using `[&_{children-selector}]:{utility-class}` to style any descendant for the parent element. I don't know why, but this way is not documented in official documentation.
#### Example:
The underscore in the code is a replacement for space. You can also use `id` and `class` selectors.
### 2. Styling based on Parent state (`group-*`)
Let's say you have a card component that has text, a link, and an icon inside it. When the user hovers over the card, you want to apply a style to text, link, and icon. To do that, you can put `group` class to the card element and put `group-hover:{utility-class}` to the text, link, and icon that you want to style.
The `group` state is not limited to hover. You can also apply it for other states like `active`, `focus`, and `checked`.
#### Example:
In the code above, you can see there are `group-hover:text-white` inside the element with `group` class
### 3. Styling based on Sibling state (`peer-*`)
You can use `peer-{state}:{utility-class}` to style an element based on its sibling state.
#### Example
In the demo above, you can see that the error message will only be visible when the input element (sibling) has `invalid` state.
### 4. Styling based on descendant (`has-*`)
There is also a way to style an element based on its children or descendants. The example use case for this is when looping a post list that the post item can contain an image or not.
#### Example
In real use cases, you probably will use javascript logic instead of using `has-[{element-selector}]` to style based on the descendant element. But, `has-*` also supports for descendant state.
In the demo above, you can see that I used `has-[img:hover]` to change the background when the image hovered. You can use another state like `invalid`, `disabled`, `focus`, etc. This is the best use case where you can use `has-*` selector.
You can also combine `has-*` with another modifier like `peer-has-*`.
## Writing and Customizing Classes
Tailwind CSS supports some ways to write and customize utility classes
### 5. Custom class with Arbitrary Values
Custom class with Arbitrary Values is like writing css directly inside the class. It looks something like `text-[#09836d]` or `mr-[75px]`. You can use a class with Arbitrary as a last resort when you can't find a predefined utility class that fulfills your use case.
You can pass any value that is valid as css property value to a custom class. You can even pass Tailwind CSS variables. You can find more examples of Arbitrary values in [official documentation](https://tailwindcss.com/docs/adding-custom-styles#using-arbitrary-values).
One thing that usually becomes an issue when using a class with arbitrary value is when you need to pass a value with space. For example, when you want to pass `box-shadow` value `0 0 2px 0 #abcdef`. In this case, you can replace the space with `_`, so the class will be `shadow-[0_0_2px_0_#abcdef]`.
Keep in mind that a css class can't contain whitespace.
### 6. Color Opacity
Did you know that you can apply opacity to your color classes?. It work on classes that contain color values like `bg-{color}`, `text-{color}`, `border-{color}`. You just need to add `/{opacity-value}` after the class. The opacity value is 0 to 100 with interval 5.
#### Example
### 7. Dynamic utility classes
When using a Front-end framework like React, Next.js, or Vue with Tailwind CSS, you often encounter the case when you have to generate Tailwind CSS class based on the variables or states.
For example in a React project, you want to conditionally put a `bg-color` to a component based on `colors` variable.
```jsx
const ConditionalColor = () => {
const colors = ['red', 'green', 'blue'];
return (
<>
{
colors.map(() => <div className={`size-8 bg-${color}-500`}>The tailwind class wont work</div>)
}
</>
);
};
```
Although it will generate `bg-red-500` which is a valid Tailwind CSS class, it won't generate the css for `bg-red-500`. This is because the Tailwind CSS scans your project files and generates the class & css styles in Build time, while in the code above, the `bg-red-500` will only be available in Run time.
To solve this issue, you have to define the Tailwind CSS classes so they will get scanned in build time.
```jsx
const ConditionalColor = () => {
const colors = ['bg-red-500', 'bg-green-500', 'bg-blue-500'];
return (
<>
{
colors.map(() => <div className={`size-8 ${color}`}>The tailwind class will work</div>)
}
</>
);
};
```
### 8. Customize / Disable Tailwind container class
Tailwind CSS comes with a built-in responsive container class. The container will adjust in `xs`, `sm`, `md`, and `lg` breakpoints. By default, the container class has no padding and center positioning. But if you want to customize it, you can add container configurations in `tailwind.config.js` file.
```ts {5-8} title="tailwind.config.js"
/** @type {import('tailwindcss').Config} */
module.exports = {
...,
theme: {
container: {
center: true,
padding: '1rem'
},
},
}
```
You can also disable or remove the container class by setting `container: false` in `corePlugins` configuration.
```ts {5} title="tailwind.config.js"
/** @type {import('tailwindcss').Config} */
module.exports = {
...,
corePlugins: {
container: false
},
}
```
## Combining Utility Classes
Some utility classes can be combined with other classes in certain cases.
### 9. Combine Text size and Line height in 1 class
Usually, when you want to put a text size and line height class, you will put 2 classes, for example, `text-base` and `leading-6`. You can actually shorten them into a single class `text-base/6`. This will also work with arbitrary values or other line-height values like `text-base/[40px]` or `text-base/small`.
#### Example
### 10. Combine Width and Height in 1 class (`size`)
If you want to create a square element with the same width and height, you combine your width `w-8` and height `h-8` class into a single class `size-8`.
#### Example
### 11. Space between element (`space-*` & `gap-*`)
When displaying a list or grid, we usually need spacing between list or grid items. We often use `padding-{top/bottom/left/right}` or `margin-{top/bottom/left/right}` and end up with excess spacing in the last item.
You can solve this by using `space-*` or `gap-*` in the list or grid container. `space` works for all element displays (`block`, `flex`, `grid`, etc), while `gap-*` only works for `flex` and `grid` element.
If you use `space-*`, you have to define the direction whether vertical or horizontal spacing. Use `space-x-*` for horizontal space and `space-y-*` for vertical spacing.
#### Example
## Rarely Known Cool Stuff
Some useful Tailwind CSS utility classes you probably don't know.
### 12. Replace js `substring()` with `truncate` and `line-clamp-*`
Before I knew `truncate` and `line-clamp-*`, I usually used the javascript function `substring(0, n)` to truncate a string. However, the sentences often have inconsistent widths because each letter has a different width.
`truncate` and `line-clamp-*` solve this because they don't care about the number of letters, they only care about the number of lines.
You can use `truncate` to truncate sentences into 1 line. If you want to truncate a paragraph after, let's say 3 lines, you can use `line-clamp-3`.
#### Example
### 13. Changing Checkbox & Radio Color (`accent-*`)
A native browser color for checkbox and radio input sometimes doesn't match your design color. Luckily, we can change their colors with `accent-*`.
#### Example
### 14. Customize Input file button (`file:*`)
You can also customize the design for the browser file input button with `file:*`.
#### Example
### 15. Blur and Color filters
You can apply blur or color filters to any element such as image, text, heading, background, etc. Just put a class `blur`, `grayscale`, or any filter class into the parent element.
For backdrop filter, you can add `backdrop-blur` class. Just Go to the [official documentation](https://tailwindcss.com/docs/blur) to learn more about it.
#### Example
## Tailwind CSS VSCode Extensions
When working with Tailwind CSS, I recommend installing these extensions in your VSCode to improve your productivity.
### 16. Tailwind CSS IntelliSense
[](https://marketplace.visualstudio.com/items?itemName=bradlc.vscode-tailwindcss)
Tailwind CSS IntelliSense is the official Tailwind CSS extension for VSCode. It will help you with class autocomplete, linting, syntax highlighting, and a tooltip that contains a class overview.
### 17. Tailwind Docs

1,877,846 | Hybrid App Development: An Overview, Pros, and Cons | The demand for mobile applications has risen because customers rely heavily on these applications to... | 0 | 2024-06-05T10:01:03 | https://dev.to/lucyzeniffer/hybrid-app-development-an-overview-pros-and-cons-g1a | The demand for mobile applications has risen because customers rely heavily on these applications to undertake their routine activities. Leveraging this surge, businesses constantly look to invest in mobile app development, but budget constraints and building native apps for each platform can hinder their plan. In this scenario, choosing the hybrid approach for app development is the ideal solution. When you plan to invest in an app project with such a development approach, consider hiring a professional [hybrid app development company](https://successive.tech/hybrid-app-development-company/?utm_source=Micro+Blog&utm_medium=dev.to&utm_campaign=SEO+WORK+2), as they understand your requirements well and build a solution accordingly.
## What is Hybrid App Development?
Using a single codebase, hybrid mobile app development generates mobility solutions that can operate on several platforms, including iOS, Android, and others. This method speeds up the development process while also saving time. The ability to blend components of web and native apps to create a native-like user experience is what makes hybrid apps unique. These applications use web technologies like JavaScript, HTML, and CSS to apply business logic and design user interfaces that are easy to understand.
The most significant advantage one gets with this development mode is the capability of code reusability. One can write code once and deploy it everywhere across different platforms, simplifying the process and saving time and cost, leading to faster launch in the market.
## Pros of Hybrid App Development
**Single Codebase**
Hybrid apps use one codebase and can work across multiple platforms. This makes them desirable to businesses eager to get their app to market. It also allows them to target as many users as possible.
**Lower cost**
Because of the singular codebase and a hybrid app’s cross-platform abilities, the cost to move from one to another is greatly reduced since there is no need to build per platform. Added to this is the fact that it only takes one development team to execute the entire process, including updates, bug fixes, and features.
## Cons of Hybrid App Development
**Might Lead to Low Performance**
Hybrid apps are not the best for sleek user experiences. If you’re looking to build a high-performance game that requires sharp graphics, then a hybrid framework is not right for you. This type of app comes with these UI issues because of its dependency on a native browser; even though they are easy to update, one change can throw everything off, and glitches can occur.
**Also read** [Hybrid App Development: A Complete Guide](https://successive.tech/blog/hybrid-app-development-guide/?utm_source=Micro+Blog&utm_medium=dev.to&utm_campaign=SEO+WORK+2)
**Higher Complexity**
New tech like hybrid apps consists of less mature platforms, smaller users bases and worst-case scenario: no documentation. When building an app that works one way on a specific platform and differs in behavior on another, it might add a layer of complexity to a single codebase, which would otherwise be spread over several independent codebases. This can lead to some confusing pathways. Using technology that is not directly supported by the platform you are running it on may cause a few workarounds, which can be time-consuming.
**No Access to Native Features**
You also can’t integrate any device features you want in a hybrid app; Apple features like Touch ID would never work in a hybrid scenario unless a plugin exists. If the plugin doesn’t exist, then someone has to build it.
## Conclusion
Hybrid app development is a strategic solution for businesses looking to build with a low budget and faster time-to-market capability. This approach indeed has high-end advantages, but it can also create some issues if not handled properly. Hence, consult a professional hybrid app development company as they can utilize best practices for app development and successful deployment. | lucyzeniffer | |
1,877,845 | Enhancing Security in Web Applications with Custom Response Headers in Next.js | Explore how to elevate the security of your Next.js applications by configuring custom response headers to tackle common web vulnerabilities. | 0 | 2024-06-05T10:00:37 | https://dev.to/itselftools/enhancing-security-in-web-applications-with-custom-response-headers-in-nextjs-m58 | webdev, security, nextjs, javascript |
Here at [Itselftools.com](https://itselftools.com), we've explored and implemented numerous web development projects using Next.js and Firebase, strengthening our understanding and use of these modern technologies across over 30 projects. Today, we're diving deep into a particular aspect of web development—enhancing application security through the use of HTTP response headers.
## Security Headers: What Are They and Why Use Them?
Browsing the internet can expose users and servers to various security vulnerabilities. To mitigate some of these risks, web servers send HTTP response headers to inform the browser about how to behave when handling the site’s content. Two critical security headers are `X-Content-Type-Options` and `X-Frame-Options`.
### Understanding Our Configuration
In the provided JSON configuration, we specify settings for these headers within a Next.js project:
```json
{
"headers": [
{
"source": "/new-section/:path*",
"headers": [
{
"key": "X-Content-Type-Options",
"value": "nosniff"
},
{
"key": "X-Frame-Options",
"value": "DENY"
}
]
}
]
}
```
### Breakdown of the Configuration
- **source**: `/new-section/:path*` specifies a URL pattern that applies to paths under `/new-section/`. This pattern will match any routes that fall under this section, protecting them with specified headers.
- **X-Content-Type-Options**: Setting this header to `nosniff` tells the browser to trust the `Content-Type` headers and not try to guess the MIME types, which prevents MIME type sniffing attacks.
- **X-Frame-Options**: This header set to `DENY` prevents the site from being displayed in frames or iframes, which effectively blocks clickjacking attacks.
## Implications and Benefits
By specifying these headers, the risk associated with information leakage and unauthorized content display is significantly reduced, making the web application more secure against common attack vectors. The configuration shown is straightforward to implement and can be very effective in preventive significant vulnerabilities.
## Conclusion
Security is paramount and often underestimated in web development. Implementing security headers like the ones outlined here is an essential step in developing secure web applications. If you want to see this configuration in action across various implementations, check out some of our interactive platforms such as this application for [video compression](https://video-compressor-online.com), our tool for [testing microphones](https://online-mic-test.com), or our website that helps with [finding adjectives](https://adjectives-for.com).

1,877,844 | Top 7 Database Security Best Practices | Safeguarding your data is not just an option—it’s a necessity. Cyber threats are evolving at an... | 0 | 2024-06-05T10:00:27 | https://dev.to/dana_roth_f455b7e908d5227/top-7-database-security-best-practices-ll0 | webdev, devops, database, devsecops | Safeguarding your data is not just an option—it’s a necessity. [Cyber threats](https://www.itgovernance.co.uk/blog/global-data-breaches-and-cyber-attacks-in-2024) are evolving at an unprecedented pace, and your database could be the next target. Whether you’re managing sensitive customer information or intricate analytics, database security should be at the top of your priority list. This article dives deep into the top 7 database security best practices that will help you fortify your defenses.
Importance of Database Security
In an era where data breaches are not just common but also costly, the importance of database security cannot be overstated. Every piece of data, from personal customer information to financial records, is a potential target for cybercriminals. The consequences of a breach can range from regulatory fines and legal battles to a loss of customer trust and business reputation.
Moreover, as databases become more complex and interconnected, the potential for vulnerabilities increases. It’s not just about protecting data from external threats; insider threats and accidental leaks must also be mitigated. The integrity, confidentiality, and availability of your data are the pillars upon which database security stands. Protecting these aspects ensures not only compliance with regulations but also the smooth operation of your business.
Effective database security is a comprehensive approach that includes physical, technical, and administrative measures. It’s about creating multiple layers of defense to protect against a wide range of threats. This holistic approach ensures that even if one defense mechanism fails, others are in place to prevent a breach. As we delve into the best practices for database security, keep in mind that each recommendation is a piece of a larger puzzle designed to safeguard your digital assets.
Database Security Best Practices
Regularly Update and Patch Your Database
One of the most straightforward yet often overlooked aspects of database security is the regular updating and patching of database software. Developers continuously work on improving the security features of database management systems (DBMS) and fixing vulnerabilities. When these updates are ignored, it leaves the database exposed to known exploits.
Regular updates ensure that your database is protected against the latest threats. This process should be part of a routine maintenance schedule, with patches applied as soon as they are released. In addition to security patches, updates often include performance improvements and new features that can enhance the overall efficiency of your database.
Automating the update process can help reduce the workload on your IT team and minimize the risk of human error. Many DBMS offer automatic update features, but it’s important to monitor these processes to ensure they’re functioning correctly. Testing patches in a development environment before applying them to your production database can prevent unexpected issues.
Implement Strong Access Controls
Access control is the cornerstone of database security. It involves defining who can access your database and what actions they can perform. This practice is crucial for minimizing the risk of unauthorized access and data breaches. By implementing strong access controls, you can ensure that only authorized personnel have access to sensitive information.
The principle of least privilege should guide your access control policies. This means granting users the minimum level of access necessary for their role. For example, a marketing analyst might need to view customer data but should not have the ability to modify it. Regular reviews of access privileges are necessary to adjust permissions as roles change or employees leave the company.
Authentication methods, such as passwords, multi-factor authentication (MFA), or biometrics, add an additional layer of security. Password policies should require complex passwords that are changed regularly. MFA, which requires a second form of verification beyond just a password, significantly reduces the risk of unauthorized access.
Encrypt Sensitive Data
Encryption transforms readable data into a coded format that can only be accessed with the correct decryption key. It is one of the most effective ways to protect sensitive information, ensuring that even if data is intercepted or accessed without authorization, it remains unreadable.
Data encryption should be applied both at rest and in transit. Encrypting data at rest protects it from being accessed by unauthorized users who might gain physical access to the storage medium. Encrypting data in transit protects it as it moves across networks, preventing interception by cybercriminals.
Implementing strong encryption algorithms and managing encryption keys securely are vital components of this strategy. It’s also important to consider the performance impact of encryption and balance security needs with system efficiency.
Monitor and Audit Database Activity
Monitoring and auditing database activity is essential for detecting potential security breaches and ensuring that access controls are effective. This process involves tracking all access to the database and recording actions such as data queries, modifications, and login attempts.
An effective monitoring strategy can help identify suspicious activity, such as repeated failed login attempts or unusual data access patterns, which could indicate a security threat. Audit logs also provide valuable evidence in the event of a breach, helping to identify the source and scope of the intrusion.
Implementing automated monitoring tools can simplify the process and provide real-time alerts to potential security incidents. However, it’s important to regularly review audit logs and adjust monitoring parameters to ensure that you’re capturing relevant information without being overwhelmed by data.
Backup Data Regularly
Regular backups are a critical component of any database security strategy. In the event of data loss due to hardware failure, cyberattack, or human error, backups ensure that you can restore your database to its previous state.
Backup procedures should be established as part of a larger disaster recovery and business continuity plan. This includes determining what data needs to be backed up, how frequently backups should occur, and where backups are stored. Off-site or cloud storage can provide an additional layer of protection against physical threats, such as natural disasters.
Testing your backup and restoration processes regularly is essential to ensure that they work as expected when needed. This practice helps identify any issues before they become critical, minimizing downtime and data loss.
Limit Database Exposure and Minimize Attack Surface
Limiting database exposure and minimizing the attack surface requires a combination of stringent access controls, network segmentation, regular maintenance, encryption, and vigilant monitoring. By adopting these practices, organizations can significantly enhance their database security posture and protect their valuable data assets from cyber threats.
First and foremost, implementing strong access control measures is crucial. This involves defining user roles and granting permissions based on the principle of least privilege, ensuring that individuals have access only to the data necessary for their role. Additionally, employing robust authentication mechanisms, such as multi-factor authentication (MFA), adds an extra layer of security by verifying the user’s identity using more than one method of validation.
Network segmentation plays a vital role in minimizing the attack surface. By isolating the database servers in a secure network segment or demilitarized zone (DMZ), organizations can limit access to sensitive data and reduce the risk of lateral movement within their networks. Furthermore, utilizing firewalls and intrusion detection/prevention systems (IDPS) to monitor and control incoming and outgoing network traffic can thwart potential attacks.
Regularly updating and patching database management systems (DBMS) and associated applications is another critical step. Cybercriminals often exploit known vulnerabilities; hence, keeping software up to date closes these security gaps. Additionally, conducting routine security audits and vulnerability assessments helps in identifying and mitigating potential weaknesses before they can be exploited.
Data encryption, both at rest and in transit, ensures that even if unauthorized access is gained, the information remains unintelligible and useless to attackers. Lastly, implementing comprehensive monitoring and logging can aid in the early detection of suspicious activities, enabling timely responses to mitigate threats.
Educate and Train Employees on Permissions Management Security Best Practices
Teaching employees about permissions management security best practices is an essential step in fortifying an organization’s data integrity and safeguarding its intellectual property. Permissions management refers to the process of defining and regulating access to resources within an IT environment, ensuring that individuals have the appropriate level of access required for their role. This not only minimizes the risk of accidental or deliberate data breaches but also aids in the smooth operation of business processes by facilitating the right access to the right individuals at the right time.
A comprehensive understanding of permissions management among employees helps in creating a culture of security awareness where every member recognizes their role in maintaining the security posture of the organization. It prevents instances of ‘over-permissioning’, a common issue where users are granted more access rights than needed, which could potentially be exploited by malicious actors. Additionally, educating employees on this topic empowers them to identify and report any anomalies or vulnerabilities related to access controls, thereby acting as a first line of defense against security threats.
Moreover, regulatory compliance demands strict adherence to permissions management protocols. Many industries are subject to regulations that mandate the protection of sensitive information through stringent access controls.

canonical_url: https://blog.elest.io/n8n-api-endpoint-for-get-response/
---
Hey everyone, In this blog we are going to see how you can create API Endpoints that responds to your GET requests using N8N. During this tutorial, we will be creating the workflow using a template. You can create the same from scratch too. Before we start, make sure you have deployed N8N, we will be self-hosting it on [Elestio](https://elest.io/open-source/n8n?ref=blog.elest.io).
## What is N8N?
N8N is an open source workflow automation tool that allows you to automate tasks and workflows by connecting various applications, services, and APIs together. It provides a visual interface where users can create workflows using a node-based system, similar to flowcharts, without needing to write any code. You can integrate n8n with a wide range of applications and services, including popular ones like Google Drive, Slack, GitHub, and more. This flexibility enables users to automate a variety of tasks, such as data synchronization, notifications, data processing, and more.
## Using Template
Once you log in into N8N you will land on the canvas page of N8N. To check out different templates and use one, head over to the templates section form the left side bar.
Then search for "Creating an API endpoint" template or simply click [here](https://n8n.io/workflows/1750-creating-an-api-endpoint/?ref=blog.elest.io). Next, click on **Use workflow**.
Select the N8N instance you want to use this template for. If you have multiple N8N instances running then you can choose the appropriate one.
## Creating API Workflow
Once you are redirected back to the workflow screen you will find components like below. To start with click on the first **Webhook** component. In this component we set up the endpoint URL, authentication mechanism etc for the API.
Once you click on **Webhook** you can copy **Test URL/Production URL** , Select the HTTP Method. Here we are trying to make a **GET** request so we have selected it from the drop down menu. Let's keep Authentication as none for the simplicity but make sure while in production you add the authentication to provide security to the endpoints. Additionally we will add the last webhook component in workflow under **Respond**.
This part of workflow enables us to work on the function we want to perform and the filtering of the object once the API endpoint is hit. This component takes in input from previous webhooks and passes on to the reponse webhook. Click on **Create URL string** component to configure it.
We will be taking the input from the query section provided with the endpoint. Add the value as `{{$json["query"]["name"]}}` under string name `product`
Next we will configure the **Respond to Webhook** component. Click on this component as shown in the following images and move to the configuration part.
This is where we add the reponse we expect once someone performs `GET` request. For this example as we are expecting name as input in the query (`Joe`) and respond as `Hello Joe!`. Hence, we will add a placeholder in the response body as `Hello {{$json["product"]}}!`
## Testing Workflow
For testing your workflow you will see **Test workflow** button. Click on it and paste the endpoint URL copied from the **Webhook** component in the earlier steps. Make sure you add the query property to it. In this case it will be `?name=Joe` so the final url will look something like
```
https://n8n-9f2ud-u7774.vm.elestio.app/webhook-test/6f7b288e-1efe-4504-a6fd-660931327269?name=Joe
```
And you should see output like below.
And done! You have successfully created a simple API endpoint which reponds to **GET** request. You can form multiple such workflows based on the request type.
## **Thanks for reading ❤️**
Thank you so much for reading and do check out the Elestio resources and Official [N8N documentation](https://docs.n8n.io/?ref=blog.elest.io) to learn more about N8N. You can click the button below to create your service on [Elestio](https://elest.io/open-source/n8n?ref=blog.elest.io) and retrieve weather information based on a zip code. See you in the next one👋

Microsoft Azure is a comprehensive cloud computing platform that offers a wide range of services and solutions for businesses and developers. At the heart of Azure's architecture are several core components that work together to deliver a robust and scalable cloud infrastructure. Furthermore, Azure Microsoft's cloud computing platform, offers a comprehensive suite of services to build, deploy, and manage applications through Microsoft's global network of data centers. Understanding the core architectural components of Azure is crucial for leveraging its capabilities effectively. In this blog, I will explore these components and how they contribute to the robust architecture of Azure. I will dive into the key architectural components of Azure and explore how they also contribute to the platform's capabilities.
Azure Regions and Availability Zones
- Azure Regions
Azure regions are geographic locations around the world where Microsoft has data centers. These regions provide the physical infrastructure for hosting your applications and data while ensuring compliance with local regulations and data residency requirements. Each region consists of multiple data centers to ensure high availability and redundancy.
- Availability Zones
Availability Zones are physically separate locations within a single Azure region. Each zone is made up of one or more data centers equipped with independent power, cooling, and networking. By deploying applications across multiple Availability Zones, you can protect them from data center failures and achieve higher availability and resilience.
**Azure Resource Manager (ARM)**

1,877,840 | Common Problems with Snake Plants and How to Fix Them | Snake plants, also known as Sansevieria or mother-in-law's tongue, are popular houseplants due to... | 0 | 2024-06-05T09:55:52 | https://dev.to/growhub_ae_edbb598042ea93/common-problems-with-snake-plants-and-how-to-fix-them-147b | Snake plants, also known as Sansevieria or mother-in-law's tongue, are popular houseplants due to their hardiness and striking appearance. While they are generally low-maintenance, snake plants can still encounter problems. Knowing how to identify and fix these issues can ensure your plant remains healthy and vibrant. Here are some common problems snake plants face and how to solve them.
## **Overwatering**
**Problem:**
One of the most frequent issues with [snake plants](https://growhub.ae/products/snake-plant-sansevieria-trifasciata-40cm-to-60cm-2) is overwatering. These plants are succulents and store water in their leaves, so they do not need frequent watering. Overwatering can lead to root rot, which can be fatal.
**Symptoms:**
- Yellowing leaves
- Soft, mushy roots
- Foul odor from the soil
**Solution:**
Allow the soil to dry out completely between waterings. During the winter months, reduce the watering frequency even more. If you suspect root rot, remove the plant from its pot, cut away the rotten roots, and repot the plant in fresh, well-draining soil.
## Underwatering
**Problem:**
While snake plants are drought-tolerant, they still need occasional watering. Underwatering can cause the plant to become stressed and lose its vigor.
**Symptoms:**
- Wrinkled or curling leaves
- Brown tips
- Stunted growth
**Solution:**
Water the plant thoroughly but infrequently. Ensure the pot has drainage holes, and always empty the saucer under the pot to prevent the roots from sitting in water. Generally, watering once every 2-6 weeks is sufficient, depending on the indoor climate.
## Poor Lighting Conditions
**Problem:**
Snake plants are adaptable to various lighting conditions, but extreme low light or direct sunlight can cause problems.
**Symptoms:**
- Pale or yellow leaves
- Brown, crispy edges
- Slow growth
**Solution:**
Place your snake plant in bright, indirect light. It can tolerate low light but will thrive with moderate, indirect sunlight. Avoid placing it in direct sunlight, as this can scorch the leaves.
## Pest Infestations
**Problem:**
Snake plants can occasionally fall victim to pests such as spider mites, mealybugs, and scale insects.
**Symptoms:
**
- 1. Tiny webs or visible insects on the plant
- 2. White, cotton-like masses (mealybugs)
- 3. Sticky residue on leaves
**Solution:**
Wipe the leaves with a damp cloth to remove pests. For more severe infestations, use a mild insecticidal soap or neem oil spray. Quarantine the affected plant to prevent the pests from spreading to other houseplants.
## Leaf Damage
**Problem:**
Physical damage to the leaves can occur from handling or moving the plant. This can result in unsightly cuts or bruises on the foliage.
**Symptoms:**
- Visible cuts or bruises
- Bent or broken leaves
**Solution:**
Trim damaged leaves with clean, sharp scissors to prevent further tearing. Handle the plant gently when moving it to avoid additional damage.
## Nutrient Deficiency
**Problem:**
While snake plants do not require frequent fertilization, a complete lack of nutrients can affect their growth and health.
**Symptoms:**
- Yellowing or pale leaves
- Slow or stunted growth
**Solution:**
Fertilize your snake plant with a balanced, water-soluble fertilizer during the growing season (spring and summer). A general-purpose houseplant fertilizer diluted to half strength is ideal. Avoid over-fertilizing, as this can cause root burn.
## Root Bound
**Problem:**
Snake plants grow slowly, but over time, they can become root-bound if not repotted.
**Symptoms:**
- Roots growing out of the drainage holes
- Cracked or bulging pot
**Solution:**
Repot your snake plant every 2-3 years or when it outgrows its current pot. Choose a pot that is one size larger and use fresh, well-draining soil. This will give the roots more space to grow and the plant room to thrive.
**Fun Fact: Snake Plants and Air Quality**
Snake plants are known for their air-purifying abilities. According to a study by NASA, snake plants can remove toxins such as formaldehyde, xylene, and toluene from the air. They convert carbon dioxide into oxygen at night, making them an excellent choice for bedrooms to improve air quality while you sleep.
**Conclusion**
Snake plants are a wonderful addition to any home due to their resilience and aesthetic appeal. By understanding and addressing the common problems they face, you can keep your snake plant healthy and thriving for years to come. Remember, the key to a healthy snake plant is proper watering, adequate light, and occasional care.

Performance testing is a process that leverages automated tools to simulate different user loads on a system—ranging from normal to peak and even abnormal scenarios. Its purpose is to measure performance metrics such as efficiency, resource consumption, stability, security, compatibility, scalability, and reliability. The ultimate goal of performance testing is to ensure that the software performs well post-release, meeting the end-users’ expectations and requirements. Essentially, it reproduces production conditions to ascertain whether the system can withstand and function optimally under specified loads.
## Common Types of Performance Testing
Below are the two most popular performance testing methodologies:
1. **Stress Testing**: This approach tests the system's limits by pushing workloads beyond normal levels to identify breaking points. Stress testing reveals the maximum capacity the system can handle and highlights any stability issues or potential failures under stressful conditions.
1. **[Load Testing](http://apidog.com/blog/api-load-testing)**: This widely-used testing method evaluates how the system performs under expected loads, determining response times, throughput, and resource utilization when multiple users or processes are active simultaneously. Load testing helps pinpoint performance bottlenecks and verifies the system’s capability to handle anticipated user loads.
For more in-depth information, you can view this comprehensive guide on performance testing.

# Initial thoughts
<!--
Briefly introduce Kubernetes as an open-source container orchestration platform.
Mention that the article will explore the reasons why Kubernetes is a strong choice for commercial applications.
-->
Kubernetes, has emerged as a transformative force in the world of software development and deployment. Born as an open-source project under the guidance of the Cloud Native Computing Foundation (CNCF), Kubernetes has evolved into one of the most influential technologies powering modern infrastructure and application management.
Kubernetes has gained so much traction within the community that people started to use it for small usages, where the need for a container orchestrator is far from necessary. We now see Kubernetes jokes, memes, and even Kubernetes bashing.
I like Kubernetes. but I've bin an even bigger fan of the KISS principle. An efficient monolith is beautiful. An application working seamlessly on a single server is beautiful. And yet, I still recommend Kubernetes for modest commercial applications. More precisely, for modest teams (at least 3 full time developers working efficiently). Modest team and not below, because lots of advantages concerns active and collaborative development.
We choose the managed side of Kubernetes, because let's face it, it is hard (and costly) to maintain on your own below a certain tech team size. At least it better be managed from the dev team perspective.
In this article, we will uncover the reasons why Kubernetes still stands as a great choice for a wide array of commercial applications, even small and/or starting ones, for a various reasons, beyond scalability and self-healing.
# For development/developers
<!-- ## Kubernetes cost for development phase should not be an issue -->
Way too often, we underestimate the impact of an architecture choice on the team velocity. Yes, these choices do not only impact our production environment. I would dare to say that it is the least of challenges for modest teams. The biggest challenge we face is to build a product at a fast and yet sustainable pace, to hopefully become successful someday.
Some people choose an architecture or another depending on minor cloud cost differences. But the infrastructure cost on an actively maintained modest application is relatively rarely the problem. The biggest cost is (or should be) the team itself. How impactful is a 30$ a day kubernetes service when the team costs more than 2000$ a day ? Trying to save 10$ a day on these servers often leads to more than 100$ a day of team inefficiency. And there is always room for cost optimization for a given architecture without impacting performance, as described for Kubernetes in the article [FinOps EKS: 10 Tips to Reduce the Bill up to 90% on AWS Managed Kubernetes Clusters](https://dev.to/zenika/eks-10-tips-to-reduce-the-bill-up-to-90-on-aws-managed-kubernetes-clusters-epe)).
Now that we advocated for the cost of Kubernetes clusters to not be a problem for development environments, let's talk about real advantages.
<!--
Explore the various development tools and environments that Kubernetes offers.
Explain how these tools enhance developers' productivity, both locally and in development clusters.
- un environnement par branche pour une même infrastructure
- des environnements de dev surveillés au même endroit avec les mêmes outils
- des stacks iso-production
- déployer uniquement ce qui a changé
- desired state ?
-->
<!-- ## Advantage 1: A Development Productivity Enabler -->
<!-- Explain how Kubernetes facilitates creating isolated environments for each Git branch.
Discuss the advantages of having separate environments for development, testing, and production. -->
Also, Kubernetes empowers efficient development git workflows:
- One Environment Per Branch: Kubernetes allows you to create dedicated environments for each Git branch. This isolation aids testing, development, and collaboration.
- Rapid Feedback Loops: Developers can quickly iterate by deploying changes to their own environments, ensuring that new features and bug fixes are thoroughly tested.
- Collaboration: Kubernetes fosters collaborative development by providing, if needed, an environment for each contributor to validate their work before integration, each one in their single namespace.
## Advantage 1: A rich ecosystem of development tools
Kubernetes offers an extensive set of development productivity tools that are particularly valuable for developers. These tools streamline the development process, making it more efficient and enabling developers to focus on writing code rather than dealing with infrastructure complexities. From local development environments to continuous integration and deployment (CI/CD) pipelines, Kubernetes provides a wide array of resources that enhance development productivity.
You can check some maintained lists mentioned in [Kubernetes: Awesome Maintained Links You Will Keep Using Next Year](https://dev.to/zenika/kubernetes-awesome-maintained-links-you-will-keep-using-next-year-48o8).
## Advantage 2: A desired-state system to ease changes
Kubernetes, with its declarative constructs and its ops friendly approach, has fundamentally changed deployment methodologies: it allows teams to use GitOps, Thanks to the [desired-state principle](https://branislavjenco.github.io/desired-state-systems/).
When applying small changes such has configuration or single module code, Kubernetes will perform the necessary minimal actions to meet the new desired state. Once a developer understands the basics of kubernetes manifests (or Helm configuration), he can request changes without knowing how they will be performed by the system.
## Advantage 3: advanced networking and subdomain management
<!--
Explore Kubernetes' advanced networking capabilities.
Highlight how the ingress controller enhances subdomain routing and network management. -->
Kubernetes provides advanced networking capabilities:
- Ingress Controller: Kubernetes offers an Ingress Controller that allows you to manage subdomains, routing, and load balancing effectively.
- Subdomain Routing: With Kubernetes, you can route traffic to different services based on subdomains, enabling you to host multiple applications under a single domain.
Once an Ingress Controller is installed and a wildcard domain is affected to a cluster, developers can easily affect sub-domains to sub-environment and/or services, without the need of any additional service or operational teams ((always busy, aren't they ?).
## Advantage 4: ready-made solutions for stateful services
<!--
Describe Kubernetes' support for stateful applications.
Discuss how it enables the easy deployment of databases, message brokers, and other stateful services. -->
Even if we mostly move stateful services outside Kubernetes clusters in production, Kubernetes simplifies the deployment of stateful services for development and testing purposes:
- Databases: Kubernetes offers pre-packaged solutions for popular databases like MySQL, PostgreSQL, and MongoDB, making it easy to manage and scale your data stores.
- Message Brokers: You can deploy message brokers like Apache Kafka or RabbitMQ as stateful services on Kubernetes, enabling reliable communication between microservices.
For other less common stateful usages, Kubernetes provides StatefulSets, a controller that ensures stable, unique network identities and persistent storage for stateful applications.
These solutions streamline the management of stateful components, allowing you to focus on building your commercial applications.
# For early stages of production
Early stages of production life can be summed-up too often as: no time, no money, no product support, lots of bugs.
In this stressful period, various reason make Kubernetes a wise choice.
We still do not need those high-availability features that make funny jokes on small applications, but some others are valuable in this phase.
## Advantage 5: a rich ecosystem of production tools
<!--
Discuss the wide range of production tools and add-ons available in the Kubernetes ecosystem.
Explain how these tools can streamline application deployment, scaling, monitoring, and management.
-->
Kubernetes boasts a robust ecosystem of production tools that contribute to the three pillars of observability. Let's explore these essential components:
- **Monitoring:** Kubernetes provides powerful solutions such as Prometheus and Grafana for real-time monitoring and alerting. These tools ensure you can proactively maintain the health and performance of your applications.
- **Logging:** Efficient log management is crucial for troubleshooting issues in a distributed environment. Kubernetes offers tools like Fluentd and Elasticsearch to centralize and analyze logs, providing insights into the behavior of your applications.
- **Tracing:** Observing the flow of requests through various microservices is vital for understanding the performance of complex systems. Kubernetes supports tracing solutions, such as Jaeger or Zipkin, enabling you to trace requests as they traverse different components.
These production tools collectively enhance the reliability, performance, and overall observability of commercial applications deployed on Kubernetes.
## Advantage 6: self-healing and self-management mechanisms
Kubernetes has been built with self-healing and self-management in mind.
- Self-Healing: Kubernetes automatically restarts containers that fail, replaces containers, and kills containers that don't respond to your user-defined health check.
- Self-Management: Kubernetes automatically manages the lifecycle of your containers, including scaling, upgrading, and rolling back.
Hardware failure is also handled, and failing nodes/servers will trigger automatic workload balance on healthy nodes.
# When the product is successful
## Advantage 7: the features and stability of one of the most maintained open source projects
<!--
Discuss Kubernetes' extensive community support and continuous development.
Highlight the benefits of using a well-maintained open-source project for commercial applications.
-->
In the realm of open-source software, Kubernetes shines as one of the most well-maintained projects. It began as an internal tool at Google called Borg and later became open-source in 2014. Since then, it has grown into a thriving community of developers, users, and contributors who keep it actively maintained.
### Community-powered advancements
Kubernetes benefits from a diverse global community. People from various backgrounds, organizations, and cloud providers work together to continuously enhance the platform. This collaborative effort drives innovation, ensuring that Kubernetes stays at the forefront of container orchestration technology.
### Swift updates and issue fixes
A well-maintained project delivers updates and fixes problems promptly. Kubernetes exemplifies this by regularly releasing updates and addressing issues efficiently. Users can rely on a stable and evolving platform that keeps up with the fast-paced world of cloud-native technology.
### Extensive documentation
Kubernetes places a strong emphasis on providing clear documentation and resources. This commitment to transparency ensures that users, regardless of their expertise, can easily access the information they need. The Kubernetes website, along with community-contributed guides, tutorials, and forums, offers valuable knowledge for users of all skill levels.
### Neutral governance
Kubernetes is governed by the Cloud Native Computing Foundation (CNCF), a neutral body that ensures no single entity dominates decision-making. This neutrality encourages a fair and adaptable solution, free from corporate bias. As a result, Kubernetes serves as a versatile and reliable option for various commercial applications.
## Advantage 8: a portable vendor-neutral platform with tight integrations
<!--
Describe Kubernetes' flexibility regarding deployment options.
Discuss how it can be used in various environments, from public clouds to on-premises data centers.
-->
Kubernetes is versatile when it comes to deployment platforms. It can be set up on:
- Cloud Providers: Kubernetes is supported on major cloud platforms like AWS, Google Cloud, and Azure, making it easy to deploy and manage your applications in the cloud.
- Private Clouds: If you prefer to run Kubernetes in your private data center, it's fully adaptable to private cloud environments, offering control and security.

- Full-Fledged Deployment: For heavy production workloads, Kubernetes can scale across multiple VMs or nodes. It can handle a wide range of applications and services efficiently.
Scalability can also be considered at the application level, with a manual update of the number of pods or automatically using pods autoscalers.
## Advantage 10: high availability in continuous delivery context
Sure, a single VM is fine for serving a single starting application, and we can accommodate downtimes twice a month for deployment. But the more you lean toward continuous delivery, the more you need to consider the availability of your applications.
Kubernetes offers high-availability solutions:
- Deployments, Daemonsets, Statefulsets: Kubernetes offers multiple controllers and deployment strategies, which allows you to create multiple replicas of a single application. This ensures that your application is highly available and can handle any unexpected load.
- Canary Deployments: Canary deployments allow you to roll out new versions of your application in a controlled manner, ensuring that users are not impacted by the new features.
- Blue/Green Deployments: Blue/Green deployments allow you to roll out new versions of your application alternatively to blue and green production environments, allowing complex upgrades with zero downtime deployments
These solutions ensure that your applications are highly available and can handle any type of deployment anytime.
## Advantage 11: security tools for peace of mind

1,877,808 | Understanding SQL Joins: A Comprehensive Guide | SQL (Structured Query Language) is a powerful tool used for managing and manipulating relational... | 0 | 2024-06-05T09:34:59 | https://dev.to/johnnyk/understanding-sql-joins-a-comprehensive-guide-3c9g | sql, database, sqljoins, data | SQL (Structured Query Language) is a powerful tool used for managing and manipulating relational databases. One of the most fundamental and essential features of SQL is the ability to join tables. Joins allow us to combine rows from two or more tables based on a related column between them.
In this article we will explore the different types of SQL joins, their syntax, and examples to help you understand how to use them effectively.
## What Are Joins?
In SQL, joins are operations used to combine rows from two or more tables based on a related column between them. Joins are essential in relational databases because they allow you to retrieve data that is spread across multiple tables and present it in a unified way. This is particularly useful in normalized databases where related data is stored in separate tables to reduce redundancy and improve data integrity.
## Why Use Joins?
1. Data Normalization: In relational databases, data is often divided into multiple tables to eliminate redundancy. Joins allow you to reassemble this data as needed.
2. Complex Queries: Joins enable complex queries that can extract meaningful insights from multiple related tables.
3. Data Integrity: By linking tables through joins, you maintain data integrity and consistency, ensuring that related data is accurate and synchronized.
## Types of SQL Joins
There are various types of SQL joins. Let’s explore some of the most widely used ones:
## 1.INNER JOIN
An INNER JOIN is one of the most commonly used joins in SQL. It returns only the rows that have matching values in both tables. If there is no match, the row is not included in the result set.
The INNER JOIN essentially combines the data from two or more tables based on a related column, and it filters out rows that do not satisfy the join condition.
**Syntax of INNER JOIN**
```sql
SELECT columns
FROM table1
INNER JOIN table2
ON table1.common_column = table2.common_column;
```
- table1 and table2 are the names of the tables you want to join.
- common_column is the column that exists in both tables and is used as the join condition.
- columns are the columns you want to select in the result set.
**Example of INNER JOIN**
Let’s consider two example tables: Employees and Departments.
employees table:
```lua
| id | name | department_id |
|----|---------|---------------|
| 1 | Alice | 1 |
| 2 | Bob | 2 |
| 3 | Charlie | 3 |
```
departments table:
```lua
| id | department_name |
|----|-----------------|
| 1 | HR |
| 2 | Finance |
| 3 | IT |
| 4 | Marketing |
```
Query
```sql
SELECT employees.name, departments.department_name
FROM employees
INNER JOIN departments
ON employees.department_id = departments.id;
```
Result:
```lua
| name | department_name |
|---------|-----------------|
| Alice | HR |
| Bob | Finance |
| Charlie | IT |
```
In this example, the INNER JOIN matches the department_id in the Employees table with the id in the Departments table. Only the rows where there is a match (i.e., department.id 1, 2, and 3) are included in the result set.
## 2.LEFT JOIN
A LEFT JOIN, also referred to as a LEFT OUTER JOIN, is a type of SQL join where all rows from the left table (table1) are returned regardless of whether there is a match in the right table (table2). It includes the matching rows from the right table based on a related column specified in the ON clause of the LEFT JOIN statement.
This join condition ensures that for each row from the left table, the LEFT JOIN includes the corresponding matching rows from the right table in the result set. If there is no match found in the right table, NULL values are returned for the columns from the right table.
**Syntax of LEFT JOIN**
```sql
SELECT columns
FROM table1
LEFT JOIN table2
ON table1.common_column = table2.common_column;
```
- SELECT columns specifies the columns you want to select from the combined result set.
- table1 and table2 are the names of the tables you want to join.
- LEFT JOIN indicates that you're performing a left join.
- ON table1.common_column = table2.common_column specifies the join condition, where common_column is the column that exists in both tables and is used to match rows between them.
**Example of LEFT JOIN**
Let’s consider two example tables: Customers and Orders.
customers table:
```lua
| id | name | email |
|----|---------|--------------------|
| 1 | Alice | alice@example.com |
| 2 | Bob | bob@example.com |
| 3 | Charlie | charlie@example.com|
| 4 | David | david@example.com |
```
orders table:
```lua
| id | customer_id | product | quantity |
|----|-------------|------------|----------|
| 1 | 1 | Laptop | 1 |
| 2 | 2 | Smartphone | 2 |
| 3 | 1 | Headphones | 1 |
| 4 | 3 | Tablet | 1 |
```
Query
```sql
SELECT customers.name, orders.id AS order_id, orders.product, orders.quantity
FROM customers
LEFT JOIN orders ON customers.id = orders.customer_id;
```
Result:
```lua
| name | order_id | product | quantity |
|---------|----------|------------|----------|
| Alice | 1 | Laptop | 1 |
| Alice | 3 | Headphones | 1 |
| Bob | 2 | Smartphone | 2 |
| Charlie | 4 | Tablet | 1 |
| David | NULL | NULL | NULL |
```
This query retrieves the name column from the customers table and the id (renamed to order_id), product, and quantity columns from the orders table, joining them on the id column of customers and the customer_id column of orders.
## 3.RIGHT JOIN
A RIGHT JOIN, also known as RIGHT OUTER JOIN, is a type of SQL join that returns all rows from the right table (table2) and includes matching rows from the left table (table1). The join condition is based on a related column between the two tables, specified in the ON clause of the RIGHT JOIN statement.
The RIGHT JOIN ensures that all rows from the right table are retained in the result set, and for each row from the right table, it includes the corresponding matching rows from the left table based on the join condition. If there is no match found in the left table, NULL values are returned for the columns from the left table.
**Syntax of RIGHT JOIN**
```sql
SELECT columns
FROM table1
RIGHT JOIN table2
ON table1.common_column = table2.common_column;
```
- SELECT columns specifies the columns you want to select from the combined result set.
- table1 and table2 are the names of the tables you want to join.
- RIGHT JOIN indicates that you're performing a right join.
- ON table1.common_column = table2.common_column specifies the join condition, where common_column is the column that exists in both tables and is used to match rows between them.
**Example of RIGHT JOIN**
Let’s consider two example tables: Customers and Orders.
customers table:
```lua
| id | name | email |
|----|---------|--------------------|
| 1 | Alice | alice@example.com |
| 2 | Bob | bob@example.com |
| 3 | Charlie | charlie@example.com|
| 4 | David | david@example.com |
```
orders table:
```lua
| id | customer_id | product | quantity |
|----|-------------|------------|----------|
| 1 | 1 | Laptop | 1 |
| 2 | 2 | Smartphone | 2 |
| 3 | 1 | Headphones | 1 |
| 4 | 3 | Tablet | 1 |
| 5 | NULL | Keyboard | 1 | -- Order with no associated customer
```
Query
```sql
SELECT customers.name, orders.id AS order_id, orders.product, orders.quantity
FROM customers
RIGHT JOIN orders ON orders.customer_id = customers.id;
```
Result:
```lua
| name | order_id | product | quantity |
|---------|----------|------------|----------|
| Alice | 1 | Laptop | 1 |
| Bob | 2 | Smartphone | 2 |
| Alice | 3 | Headphones | 1 |
| Charlie | 4 | Tablet | 1 |
| NULL | 5 | Keyboard | 1 | -- Order with no associated customer
```
In this result, you can see that the order with order_id 5, which has no associated customer (customer_id is NULL), appears in the result set with the customer name as NULL. This demonstrates the use of RIGHT JOIN to include records from the right table (orders table in this case) even if there is no matching record in the left table (customers table).
## 4.FULL JOIN
A FULL JOIN, also known as a FULL OUTER JOIN, is a type of SQL join that returns all rows from both the left table (table1) and the right table (table2). When there is a match between the tables based on the join condition, the result set includes the matched rows from both tables. When there is no match, the result set includes NULL values for columns from the table without a match.
**Syntax of FULL JOIN**
```sql
SELECT columns
FROM table1
FULL JOIN table2
ON table1.common_column = table2.common_column;
```
- columns specifies the columns you want to select.
- table1 and table2 are the names of the tables you want to join.
- FULL JOIN indicates that you're performing a full outer join.
- common_column is the column that exists in both tables and is used as the join condition.
**Example of FULL JOIN**
Let’s consider two example tables: customers and orders.
customers table:
```lua
| id | name | email |
|----|---------|--------------------|
| 1 | Alice | alice@example.com |
| 2 | Bob | bob@example.com |
| 3 | Charlie | charlie@example.com|
| 4 | David | david@example.com |
```
orders table:
```lua
| id | customer_id | order_date | total_amount |
|----|-------------|------------|--------------|
| 1 | 3 | 2024-05-01 | 150 |
| 2 | 2 | 2024-05-02 | 200 |
| 3 | 1 | 2024-05-03 | 100 |
| 4 | 5 | 2024-05-04 | 80 |
```
Query:
```sql
SELECT customers.name, orders.id AS order_id, orders.order_date, orders.total_amount
FROM customers
FULL JOIN orders ON customers.id = orders.customer_id;
```
Result:
```lua
| name | order_id | order_date | total_amount |
|---------|----------|------------|--------------|
| Alice | 3 | 2024-05-03 | 100 |
| Bob | 2 | 2024-05-02 | 200 |
| Charlie | 1 | 2024-05-01 | 150 |
| David | NULL | NULL | NULL |
| NULL | 4 | 2024-05-04 | 80 |
```
The FULL JOIN ensures that all rows from both tables are included in the result, with NULLs in place where there is no match.
## 5.CROSS JOIN
A CROSS JOIN is a type of SQL join that returns the Cartesian product of the two joined tables. This means that each row from the first table is combined with each row from the second table. The result set includes all possible combinations of rows from both tables.
**Example of CROSS JOIN**
Let’s consider two example tables: customers and orders.
customers table:
```lua
| id | name | email |
|----|---------|--------------------|
| 1 | Alice | alice@example.com |
| 2 | Bob | bob@example.com |
| 3 | Charlie | charlie@example.com|
| 4 | David | david@example.com |
```
products table:
```lua
|id | name | amount |
|----|------------|--------------|
| 1 | laptop | 150 |
| 2 | mouse | 200 |
| 3 | keyboard | 100 |
| 4 | speaker | 80 |
```
We want to create a Cartesian product of the customers and products tables.
Query:
```sql
SELECT customers.name AS customer_name, products.name AS product_name, products.amount
FROM customers
CROSS JOIN products;
```
Result:
The CROSS JOIN will combine each row from the customers table with each row from the products table, resulting in the Cartesian product of the two tables. Here is what the result will look like:
```lua
| customer_name | product_name | amount |
|---------------|--------------|--------|
| Alice | laptop | 150 |
| Alice | mouse | 200 |
| Alice | keyboard | 100 |
| Alice | speaker | 80 |
| Bob | laptop | 150 |
| Bob | mouse | 200 |
| Bob | keyboard | 100 |
| Bob | speaker | 80 |
| Charlie | laptop | 150 |
| Charlie | mouse | 200 |
| Charlie | keyboard | 100 |
| Charlie | speaker | 80 |
| David | laptop | 150 |
| David | mouse | 200 |
| David | keyboard | 100 |
| David | speaker | 80 |
```
The CROSS JOIN is especially useful for generating combinations and creating test data, but it should be used with caution due to the potential size of the result set. Understanding how to use CROSS JOIN can greatly enhance your ability to work with and analyze relational data.
## 6.SELF JOIN
A SELF JOIN is a type of SQL join where a table is joined with itself. This is useful when you want to compare rows within the same table. It allows you to create relationships between rows in the same table based on certain conditions.
**Syntax of SELF JOIN**
```sql
SELECT t1.column1, t2.column2
FROM table t1
JOIN table t2 ON t1.common_column = t2.common_column;
```
- t1 and t2 are aliases for the same table.
- common_column is the column that exists in both instances of the table and is used as the join condition.
**Example of SELF JOIN**
Let’s consider an example with an employee table named employees.
employees table:
```lua
| id | name | manager_id |
|----|---------|------------|
| 1 | Alice | 3 |
| 2 | Bob | 3 |
| 3 | Charlie | NULL |
| 4 | David | 2 |
```
We want to retrieve the names of employees and their respective managers.
Query:
```sql
SELECT e1.name AS employee_name, e2.name AS manager_name
FROM employees e1
JOIN employees e2 ON e1.manager_id = e2.id;
```
Result:
The table employees is joined with itself using aliases e1 and e2. The join condition is based on the manager_id column in e1 matching the employee_id column in e2, establishing a relationship between employees and their respective managers.
Here is what the result will look like:
```lua
| employee_name | manager_name |
|---------------|--------------|
| Alice | Charlie |
| Bob | Charlie |
| David | Bob |
```
The SELF JOIN is a powerful SQL technique that enables you to join a table with itself, allowing for comparisons and relationships between rows within the same table. Understanding how to use SELF JOIN can be beneficial in various scenarios, especially when dealing with hierarchical data or comparing records within a dataset.
## Conclusion
Understanding SQL joins is necessary for anyone working with relational databases, as it allows for efficient data manipulation and extraction. By mastering these join techniques, you gain the ability to combine data from multiple tables, extract valuable insights, and make informed decisions based on relational data.
Whether you’re a beginner learning SQL or an experienced professional, having a solid understanding of SQL joins is a foundational skill that will serve you well in your database querying endeavors.
To further enhance your knowledge and skills in SQL, consider exploring advanced topics such as subqueries, window functions, and data modeling. Additionally, practice implementing SQL joins in real-world scenarios to reinforce your understanding and proficiency.
By continually learning and practicing SQL joins, you’ll be better equipped to handle complex data analysis tasks and contribute effectively to data-driven decision-making processes in your organization.
Happy querying!

published: true
description: In this quick guide, we will learn how to modify theme for Angular Material 18 with CSS variables
tags: angular,angularmaterial,webdevelopment,materialdesign
cover_image: https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dbe3cl5lagw4qcwnt7ng.png
canonical_url: https://angular-material.dev/articles/angular-material-theming-css-vars
---
> In this quick guide, we will learn how to modify theme for Angular Material 18 with CSS variables.
## Creating Project with Angular Material 18
```bash
npm i -g @angular/cli
ng new angular-material-theming-css-vars --style scss --skip-tests --defaults
cd angular-material-theming-css-vars
ng add @angular/material
```
And select answers as below:
```bash
? Choose a prebuilt theme name, or "custom" for a custom theme: Custom
? Set up global Angular Material typography styles? Yes
? Include the Angular animations module? Include and enable animations
```
## The define-theme mixin
Take a look at `src/styles.scss`. Notice the usage of `define-theme` mixin:
```scss
// Define the theme object.
$angular-material-theming-css-vars-theme: mat.define-theme(
(
color: (
theme-type: light,
primary: mat.$azure-palette,
tertiary: mat.$blue-palette,
),
density: (
scale: 0,
),
)
);
```
We are going to make changes in above code later on to achieve customizations through CSS custom properties.
## CSS custom properties emitted by theme mixins
To further customize your UI beyond the `define-theme` API, you can manually set these custom properties in your styles.
For example, take a look at below code snippets:
```html
<mat-sidenav-container>
Some content...
<mat-sidenav>
Some sidenav content...
<mat-checkbox class="danger">Enable admin mode</mat-checkbox>
</mat-sidenav>
</mat-sidenav-container>
```
```scss
@use '@angular/material' as mat;
$light-theme: mat.define-theme();
$dark-theme: mat.define-theme((
color: (
theme-type: dark
)
));
html {
// Apply the base theme at the root, so it will be inherited by the whole app.
@include mat.all-component-themes($light-theme);
}
mat-sidenav {
// Override the colors to create a dark sidenav.
@include mat.all-component-colors($dark-theme);
}
.danger {
// Override the checkbox hover state to indicate that this is a dangerous setting. No need to
// target the internal selectors for the elements that use these variables.
--mdc-checkbox-unselected-hover-state-layer-color: red;
--mdc-checkbox-unselected-hover-icon-color: red;
}
```
Notice that we are change colors of checkbox through `--mdc-checkbox-unselected-hover-state-layer-color` and `--mdc-checkbox-unselected-hover-icon-color` CSS properties in `.danger` class.
These CSS custom properties emitted by the theme mixins are derived from [M3's design tokens](https://m3.material.io/foundations/design-tokens/overview).
This approach requires you to inspect each and every component, find out the needed CSS custom properties and then change them.
But, there is a better and scalable way to achieve theme customizations.
## Using `sys` variables
There are total 3 properties (a.k.a. dimensions) allowed in `define-theme` mixin.
1. `color` - [Optional] A map of color options
2. `typography` - [Optional] A map of typography options.
3. `density` - [Optional] A map of density options.
With `color` and `typography` maps, apart from main properties, Angular Material team has introduced a new property called `use-system-variables` of type boolean.
Let's use the in our theme mixin:
```scss
$angular-material-theming-css-vars-theme: mat.define-theme(
(
color: (
theme-type: light,
primary: mat.$azure-palette,
tertiary: mat.$blue-palette,
use-system-variables: true, // 👈 Added
),
typography: (
use-system-variables: true, // 👈 Added
),
density: (
scale: 0,
),
)
);
```
After above, we will also need to include 2 more mixins:
```scss
:root {
@include mat.all-component-themes($angular-material-theming-css-vars-theme);
@include mat.system-level-colors($angular-material-theming-css-vars-theme); // 👈 Added
@include mat.system-level-typography($angular-material-theming-css-vars-theme); // 👈 Added
}
```
If you inspect the output in browser, you will notice that majority of the Angular Material CSS Custom Properties (`--mat-*` and `--mdc-*`) now read values from `--sys-*` CSS variables. Take a look at below screenshot for example:
This means that we can simply change a particular set of `--sys-*` CSS variables to achieve the theme we want. But, what are all the possible sys variables?
### All possible sys variables
The `--sys-*` variables are generated for 2 dimensions: color and typography. So, all the sys variables should be supporting all possible values of color and typography. And to get all the possible values, we can simply take a look at [Reading color roles](https://material.angular.io/guide/theming-your-components#reading-color-roles) and [Reading typescale properties](https://material.angular.io/guide/theming-your-components#reading-typescale-properties).
{% embed https://dev.to/shhdharmen/unpublished-video-4cbn-2e25-temp-slug-3127604?preview=82ac59eb30e1d6fa684bbf0523a92740d1ebca1085539da0db1f85ac2532afc6908ff20bfdd23460547aa9a50f368e97308ca022eeff1761fcac0bcb %}
### Finding and modifying right sys variable
So, if you want to modify color role `primary`, you would modify `--sys-primary` variables. Similarly, for `surface`, `secondary`, `on-primary`, you would modify `--sys-surface`, `--sys-secondary` and `--sys-on-primary`.
And for typography, to change `body-large` level's `font`, we would modify `--sys-body-large-font` variable.
### Changing `mat-flat-button`'s color and background color
Let's take an example of `mat-flat-button`. Let's use it in `app.component`:
```html
<button mat-flat-button>Flat Button</button>
```
```ts
import { Component } from '@angular/core';
import { MatButtonModule } from '@angular/material/button'; // 👈 Added
@Component({
selector: 'app-root',
standalone: true,
imports: [MatButtonModule], // 👈 Added
templateUrl: './app.component.html',
styleUrl: './app.component.scss',
})
export class AppComponent {
}
```
Now, you can simply go to browser, open the inspector, and simply change `--sys-primary` and `--sys-on-primary` variables to see the changes:
{% embed https://dev.to/shhdharmen/unpublished-video-53c8-45bl-temp-slug-5857619?preview=97b9072cef0c755aef0bd6f6fe5780313a6b80896c98131d4fd305a3981d483669625e12ab9a87c6257cfd267653e281bdd244c5aa587f007a3c20e1 %}
### Using `@material/material-color-utilities` library
Another way to change sys variables is using the [`@material/material-color-utilities`](https://www.npmjs.com/package/@material/material-color-utilities).
Let's install it:
```bash
npm i @material/material-color-utilities
```
Next, we will use it's `argbFromHex`,`themeFromSourceColor` and `applyTheme` functions to generate all sys variables.
```ts
generateDynamicTheme(ev: Event) {
const fallbackColor = '#005cbb';
const sourceColor = (ev.target as HTMLInputElement).value;
let argb;
try {
argb = argbFromHex(sourceColor);
} catch (error) {
// falling to default color if it's invalid color
argb = argbFromHex(fallbackColor);
}
const targetElement = document.documentElement;
// Get the theme from a hex color
const theme = themeFromSourceColor(argb);
// Print out the theme as JSON
console.log(JSON.stringify(theme, null, 2));
// Identify if user prefers dark theme
const systemDark = window.matchMedia(
'(prefers-color-scheme: dark)'
).matches;
// Apply theme to root element
applyTheme(theme, {
target: targetElement,
dark: systemDark,
brightnessSuffix: true,
});
const styles = targetElement.style;
for (const key in styles) {
if (Object.prototype.hasOwnProperty.call(styles, key)) {
const propName = styles[key];
if (propName.indexOf('--md-sys') === 0) {
const sysPropName = '--sys' + propName.replace('--md-sys-color', '');
targetElement.style.setProperty(
sysPropName,
targetElement.style.getPropertyValue(propName)
);
}
}
}
}
```
Lastly, we will add the `input` to allow user to change the colors:
```html
<mat-form-field>
<mat-label>Change Seed Color</mat-label>
<input
type="text"
matInput
placeholder="#XXXXXX"
(change)="generateDynamicTheme($event)"
/>
</mat-form-field>
```
Now, if you look at the output, observe that all the `--sys-*` colors are generated dynamically according to Material 3 design specs.
{% embed https://dev.to/shhdharmen/unpublished-video-35l7-3h5k-temp-slug-5002742?preview=4e40808dafc42d86b2e1d606f3fa587edd992ddc0378a2b55e2f21cdc0d3c3622b664a2a4f86aaa7655d3032a7e31548a32cd722277b74dc10ea20bb %}
> **Heads up!**
> `@material/material-color-utilities` library generates colors based on Material 3 design guidelines, and hence, it maybe possible that the seed color user enters, may not be available in generated `--sys-*` variables.
## Conclusion
We learned that `define-theme` mixin emits custom CSS properties like `--mdc-checkbox-unselected-hover-state-layer-color` and `--mdc-checkbox-unselected-hover-icon-color`. And we can change them to modify the theme. But, a drawback would be you will have to find out such properties for each and every components.
Next, we saw that it is also possible to modify a set of `--sys-*` variables to achieve the desired customizations in theme. With `--sys-*`, we have access to color roles and typescale properties for all typography levels.
Lastly, we learned the usage of `@material/material-color-utilities` library and how it is very much helpful in creating the dynamic themes.

No ambiente de negócios atual, a predominância de extrovertidos é evidente, especialmente em espaços onde a comunicação verbal e a assertividade são altamente valorizadas. No entanto, essa dinâmica muitas vezes resulta em um desequilíbrio, onde vozes mais calmas e reflexivas são silenciadas. Pessoas introvertidas, que tendem a falar menos e de maneira mais ponderada, frequentemente encontram dificuldades para se expressar em meio ao turbilhão de ideias e opiniões extrovertidas. Esse cenário não só limita a diversidade de perspectivas, mas também pode afetar negativamente a inovação e a criatividade nas equipes.
Gerentes que reconhecem o valor das contribuições introvertidas têm adotado práticas mais inclusivas. Uma das estratégias eficazes é a realização de consultas em ambientes seguros, como reuniões individuais (1:1). Essas sessões proporcionam um espaço onde as pessoas introvertidas se sentem acolhidas e seguras para compartilhar suas ideias sem a pressão do grupo. Ao criar essas oportunidades de expressão, os líderes não apenas fortalecem a confiança dos indivíduos, mas também enriquecem o processo de tomada de decisão com insights valiosos que poderiam ser perdidos em um ambiente dominado por extrovertidos.
A introspecção, uma característica marcante das pessoas introvertidas, é frequentemente a fonte de uma capacidade analítica aguçada. Momentos de reflexão profunda permitem que essas pessoas desenvolvam insights detalhados e soluções inovadoras para problemas complexos. Ao valorizar e aproveitar essas habilidades analíticas, as organizações podem melhorar significativamente a qualidade de suas decisões estratégicas. Reconhecer e incentivar a contribuição introspectiva pode, portanto, transformar desafios em oportunidades de crescimento e inovação.
Ao ajustar suas abordagens e práticas de gestão, líderes podem criar um ambiente mais equilibrado e diversificado, onde tanto extrovertidos quanto introvertidos têm suas vozes ouvidas e valorizadas. Essa inclusão não só promove um ambiente de trabalho mais saudável e produtivo, mas também garante que todas as habilidades e perspectivas únicas sejam utilizadas para o benefício da organização como um todo.

**Q1. What is JavaScript, and what are its key features?**
Ans: JavaScript is a scripting language primarily used for enhancing web pages with dynamic content and interactivity. It is lightweight and versatile, supporting various programming paradigms such as object-oriented and functional programming. Key features include dynamic typing, prototypal inheritance, and first-class functions.
**Q2. What are the data types in JavaScript?**
Ans: JavaScript has several built-in data types, including numbers, strings, booleans, null, undefined, and symbols (added in ES6). Additionally, objects and functions are considered reference types in JavaScript.
**Q3. What is the difference between == and === operators?**
Ans: The == operator performs type coercion, meaning it attempts to convert the operands to the same type before comparing them. On the other hand, the === operator, also known as the strict equality operator, compares both the value and the type of the operands.
**Q4. What is hoisting in JavaScript?**
Ans: Hoisting is a JavaScript behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase. This means that you can access variables or functions before they are declared.
**Q5. Explain the difference between let, const, and var.**
Ans: var has function scope and can be redeclared and reassigned. let has block scope and can be reassigned but not redeclared. const has block scope and cannot be reassigned or redeclared. | lalyadav |

É comum sentir que suas conquistas são resultado de sorte ou de engano, ao invés de mérito próprio.
#### Causas da Síndrome do Impostor
- **Pressão por Conhecimento Constante**: A necessidade de estar sempre atualizado com as novas tecnologias pode ser esmagadora.
- **Comparação com Outros**: Comparar-se constantemente com colegas pode levar à sensação de não estar à altura.
- **Medo de Falhar**: O medo de cometer erros ou falhar em projetos pode paralisar.
- **Falta de Reconhecimento**: A ausência de feedback positivo pode reforçar a sensação de inadequação.
Esses fatores podem resultar em burnout, baixa autoestima e evitação de novos desafios.
#### Dicas para Superar a Síndrome do Impostor
1. **Reconheça Seus Sentimentos**: Entender que é comum sentir-se como um impostor é o primeiro passo para superá-los. Aceite esses sentimentos sem se deixar dominar por eles.
2. **Compartilhe com Colegas**: Falar sobre suas inseguranças com outros desenvolvedores pode ser extremamente reconfortante. Muitas pessoas na área passam ou passaram por isso.
3. **Estabeleça Metas Realistas**: Definir metas alcançáveis e celebrar cada conquista, por menor que seja, ajuda a construir confiança ao longo do tempo.
4. **Aprenda com seus Erros**: Encarar os erros como oportunidades de aprendizado, e não como falhas, é crucial para o crescimento profissional.
5. **Busque Orientação**: Ter um mentor pode fornecer a perspectiva e o apoio necessários para enxergar seu progresso e suas habilidades de forma mais clara.
6. **Pratique Autocompaixão**: Seja gentil consigo mesmo. Todos cometem erros e isso faz parte do processo de aprendizado e crescimento.
### Conclusão
Enfrentar a Síndrome do Impostor é essencial para o sucesso e bem-estar na carreira de programação. Lembre-se de que suas habilidades são valiosas, independentemente dos desafios enfrentados. Acredite em si mesmo e continue avançando – você é mais capaz do que imagina! | josimar_canejo |

There was a discussion at [Clearleft](https://clearleft.com/) recently about browser support. [Rich has more details](https://clearleft.com/thinking/a-modern-approach-to-browser-support) but the gist of it is that, even though we were confident that we had a good approach to browser support, we hadn’t written it down anywhere. Time to fix that.
This is something I had been thinking about recently anyway—see my post about [Baseline and progressive enhancement](https://adactio.com/journal/21128)—so it didn’t take too long to put together a document explaining our approach.
You can find it at [browsersupport.clearleft.com](https://browsersupport.clearleft.com/)
We’re not just making it public. We’re releasing it under a [Creative Commons attribution license](https://creativecommons.org/licenses/by/4.0/). You can copy this browser-support policy verbatim, you can tweak it, you can change it, you can do what you like. As long you include a credit to Clearleft, you’re all set.
I think this browser-support policy makes a lot of sense. It certainly beats trying to browser support to specific browsers or version numbers:
> We don’t base our browser support on specific browser names and numbers. Instead, our support policy is based on the capabilities of those browsers.
The more organisations adopt this approach, the better it is for everyone. Hence the liberal licensing.

1,877,822 | Getting started with Phoesion Glow, the backend service development solution for human beings | Phoesion Glow is a cloud-native framework designed for dotnet (micro-)services with features like... | 0 | 2024-06-05T09:25:53 | https://dev.to/gepa21/getting-started-with-phoesion-glow-the-backend-service-development-solution-for-human-beings-437e | dotnet, devops, cloud, backend | [Phoesion Glow](https://glow.phoesion.com) is a cloud-native framework designed for dotnet (micro-)services with features like service-bus, load-balancing, scaling, logging/tracing, monitoring and cluster management, service-to-service discovery/communication and more. It also includes a lot of GUI/CLI developer tools (eg. aspire-like dashboards) and build-in Distributed application services like persistent key-value storage (caching), Mutexes, Job-Scheduling, State-Machines, FeatureFlags etc.
**To get started without installing ANY tools, you can give it as quick try using docker containers, by :**
1. [Downloading the "hello world" sample code](https://files.phoesion.com/Samples/HelloWorldSample.zip)
2. Start the Reactor service container using : ```sh
docker run --name reactor-2.x -d -p 80:80 -p 443:443 -p 15000-15010:15000-15010 -p 16000:16000 phoesion/phoesion.glow.reactor-dev
```
3. Run the sample (using Visual Studio)
4. Open [http://localhost/HelloWorld/Greeter/SayHello](http://localhost/HelloWorld/Greeter/SayHello) and you should see a "Hello World" response.
**What happened behind the scenes to produce that response?**
The ingress/mediator service *(running in container)* received the http request and, using the service-bus *(also in container)*, made an RPC call to your service *(running in visual studio)*, that handled it and returned the response. All this happened automatically, without needing to configure any of them! and it's because all components were build from the ground-up to work together as part of a complete (opinionated) solution
**To get the full developer experience, including developer dashboard, i recommend installing the tools:**
1. Stop/Delete the reactor container from docker *(it will not be needed anymore)*
2. Close Visual Studio *(so new templates can be installed)*
3. [Download and install the tools (Blaze)](https://glow-docs.phoesion.com/downloads/Downloads_Blaze.html?tabs=oses-1)
Now, open up the sample code again in Visual Studio and run the service. The **developer dashboard** will pop-up giving your visibility to you service metrics, structured logging, tracing and more. Your are now fully setup to start developing services using Phoesion Glow!
There a lot of [samples demonstrating the capabilities of Glow](https://github.com/Phoesion/Glow-Samples), have a look and try them out!
**Some notable samples include :**
* [1\_REST](https://github.com/Phoesion/Glow-Samples/tree/master/1_REST) : a lot of examples for creating your web APIs
* [2\_Interop ](https://github.com/Phoesion/Glow-Samples/tree/master/2_Interop): service to service communication.
* [10\_AspHosting ](https://github.com/Phoesion/Glow-Samples/tree/master/10_AspHosting): running ASP services in Glow
* [0b\_Logging ](https://github.com/Phoesion/Glow-Samples/tree/master/0b_Logging): structured logging sample
* [27\_\* - 31\_\* (AppXXX services)](https://github.com/Phoesion/Glow-Samples/tree/master/30_AppJobs) : distributed application services like job scheduling, state machines, mutexes and caches.
If you find it interesting and would like to know more information and how to run/deploy your services in your cloud or on-premises let me know.

And I am only just 14.5 years old (15yrs soon) , And I was thinking for some months now decided to document my programming journey so it may be very long as I am writing as I am thinking :)
# 01 Hello World
During the pandemic (in my 6th grade) , there was an ad very famous in Indian TV channels of some organization who teaches 'Coding' for students . (Only Indians know the name comment below) .
I was wondering wtheck is the coding ? Then I found out its some magical spells to code any app . I know some little about what are pixels and how they work , So I thought its just writing color of every possible pixel of the app ...
CODING (according to me) :
```
255,255,255
0,0,0
...
```
Yeh , THIS is the code (fr).
So after struggling for a while in internet I found out that its not like that ...
Coding is for geniuses , and I am a genius but in maths physics (only for my family) , Back then i was able to solve ques of some higher grades , but not ready to understand what coding is ?
I found some ytubers saying coding is for babies and all , and realised OK Im not genius and enough intelligent to understand this BUT LETS GIVE IT A TRY!!
From then I started coding on my Father's old scrap laptop (*acer orange color windows7) , And After following some tutorial I thought to code we have to make a file like `my_life_my_c0de.java` and its done just open it the code will run automatically ...
BUT you all know its not like that ...
The file was not running ?? You may feel i was a fool (iwas) , But i was only in 6th grade (just moved) .
Some how , after copy pasting some ytubers code in my notepad , (bash script for calculator) , It was working !!
I thought yeh , coding is for great people with great computers , so that they can work in java , c , python .... I am only allowed to use cmd ...
# 02 Traceback Error : Learning() does not exists
So yeh , after my first achievement (a cmd calculator) , I was just copying and saving the code (cmd files) for different projects and running them , I thought yeh thats coding Im learning ..
And the best part is
I didnt knew about anything like variables, functions , even operations , But able to code (copy&paste**) a text based game in cmd .
So yeh , after this A life changing book came to me ... (not recommended it was life changing bcz it taught me how to install python).
# 03 pip install python==2.0.0
My sister was in 11th grade , (and i had wasted my 1 yr) . She took computer science as additional subject (cbse**).
I thought oh boi lets give that book a try , It was about python , and i didn't knew about python at that time ... So I read that completely and installed python==2.0.0 (i guess , i couldn't remember the exact version , but I installed it because I thought 3.x.x is for genius (again*) , but surely it was 2.x.x , when python logo wasn't yellow-blue snake it was literally this 🐍 yeh green snake)
I downloaded it , and the python ide replaced my notepad , then I learned about many things , made notes of everything single thing (my notes was >> the actual docs btw) . And was learning/just remembering ,
My logic building was at the level of a chimp ...
But yeh , I learned turtle graphics , pygame (for pygame i had to update my python to 3.x.x).
# 04 sudo heck websites
After all , I decided to be a hecker (bcz they are cool) , but the reality was they are dum (somewhat) ,
I learned some pentesting and all (forgot 90-95%) ,
But there was 1 attack which shifted my interests ...
```
XSS - Cross Site Scripting Attack
An attack in which the js code is injected through different input tags very common for some websites ...
```
I even wrote a mail to amazon that I found A bug in jeffs business , They said "You lil boi , shut UP ! , *"Its not a bug Its a feature..."* , but your mail was like a professional btw..."
And yeh , I decided to quit et' ...
But my interests in web dev came from the XSS.
# 05 npm install js
So yeh , I learned HTML (in 3 days) CSS (in a week 😢) JS (till now , i just copy paste from docs ) ,
I learned about some general features of a proglang like vars , funcs , oops(i completetly understood its need just 3 months ago , also im not a oop or fp guy , im fpoop guy who is a minimalist also) , and all with some inner workings also ....
AND ALL THIS WITH NO PROJECT WHICH MEANS NO LEARNING 👏
# 06 The Tutorial Hell
After these , I tried REACT , made a project (my first react project) , which i also hosted you can also check it [https://texthelp.netlify.app](https://texthelp.netlify.app)
And now I started loving making project , and now I was also falling into tutorial hell , for everything i was searching tutorial ,
I had even learned SQL , PHP for backend through tutorials and made an auth , crud , and i left that ...
After all I made some projects (mostly are broken)
But then the age of hype came into my life ...
# 07 winget install hype
Yeh , I consumed tech yt a lot , just thought , web3 is future , qc will take classical computers , chads=c++ , dsa is everything , webdev = mern , learn watching tutorials and yeh dats it ...
I think its nothing more to tell about me at that time , I WAS just a fool again ....
# 08 C++ ooh yeeh 🗿
Yeh , I learned C++, and it was beautiful,horrible and neutral at same time ,
I even crossed 1400+ rating on codechef 2* rated coder btw in just 6 months and quit that
I learned some dev tutorial again ,
But then the age of enlightenment came and helped to me
# 09 The age of enlightenment
At this point of time , I realized , Im not learning anything ...
I have to make projects on my own , contribute to opensource , cp leetcode is a fraud, webdev is not MERN only , there is a lot more , Why to use any library/framework ? Why not build your own ?
Why to code in existing programming language ? Why not build your own ?
Why to code in father's pc ? Why not buy your own ? (impoor**)
Why to think shit thoughts ? Why not write it in a post ?
....
All these thoughts made to feel my existence .
And Now i was ready to realize that programmers on internet sometimes misguide , or they just haven't taught us to build anything you want ?
We don't ques why to learn functions ? oops ? or React ?
They just force you (with tons of content of something) to learn that !!
They just told you the tip of the iceberg , There is a lot more ...
React ! No its boring !!
Solid is a solid framework ...
But yes I know that React and that framework of that Triangle company is very famous and most commonly used ...
But as a developer we should explore a lot ...
<i>"How a software engineer is a software engineer if he hadn't explored any software ? " </i>
That was my thought which made me to levitate in air (fr) .
AND the actually serious phase of my programming journey started ...
# 10 Latest Logs
So , this section is about some latest logs , my latest works i did and learned ...
As you had read my philosophy of coding ...
I started building things in my own version , like a code editor (inspired from tsoding) , a proglang , a physics engine in go [Physix.go](https://github.com/rudransh61/Physix-go), a CSS framework revolutionizing framework (not good but idea is revolutionizing ) [NEXTGENCSS](https://github.com/rudransh61/NextGenCSS-) pls read the readme , and tell your thoughts about this experiment of nextgencss in comment pls ....
I also contributed in some OPENSOURCE repository ...
And promotes it ...
I hope you liked my journey , currently , im doing some projects for fun and writing a book (free) to make a physics engine (almostdone 1st edition soon , comment below about this idea pls...)
Pls star the [physics engine repository](https://github.com/rudransh61/Physix-go) as it encourages us ...
So yeh , that was my thoughts , I am a bad developer , but i will improve myself , And i hope you all will also ... :) | rudransh61 |

That's what vasculitis is, like a condition that causes inflammation in the walls of blood vessels making it harder for blood to flow through. This can harm organs and lead to health issues.
There are forms of vasculitis that affect different types of blood vessels. While the exact cause is often unclear, factors like age, genetics, ethnicity, smoking habits and certain diseases can contribute to its development.
Early symptoms may include fever, fatigue, or weight loss. Depending on which organs are affected you might also notice skin rashes, numbness, difficulty breathing, or even signs like blood in stool or vomit.
Diagnosing vasculitis typically involves blood tests and imaging procedures. Sometimes taking a small tissue sample. While there isn't a cure, treatments such as medications, plasma exchange therapy and experimental advanced therapies can effectively help manage the condition.
The crucial thing is to act! If you notice any concerning symptoms it's important to seek attention. With diagnosis and treatment strategies, in place coping with vasculitis and maintaining a lifestyle is achievable.

.
#### Basic Syntax and Usage
The spread operator is represented by three consecutive dots (`...`). It allows an iterable (such as an array or object) to be expanded in places where multiple elements or properties are expected.
```javascript
// Example with arrays
const numbers = [1, 2, 3];
const moreNumbers = [...numbers, 4, 5, 6];
console.log(moreNumbers); // Output: [1, 2, 3, 4, 5, 6]
// Example with objects
const person = { name: 'Alice', age: 25 };
const updatedPerson = { ...person, age: 26, city: 'New York' };
console.log(updatedPerson); // Output: { name: 'Alice', age: 26, city: 'New York' }
```
#### Advanced Use Cases with Arrays
**Merging Arrays**
The spread operator can be used to merge arrays effortlessly:
```javascript
const array1 = [1, 2, 3];
const array2 = [4, 5, 6];
const mergedArray = [...array1, ...array2];
console.log(mergedArray); // Output: [1, 2, 3, 4, 5, 6]
```
**Copying Arrays**
Creating a shallow copy of an array is straightforward with the spread operator:
```javascript
const originalArray = [1, 2, 3];
const copiedArray = [...originalArray];
console.log(copiedArray); // Output: [1, 2, 3]
```
**Combining with Array Methods**
The spread operator can be combined with other array methods for more complex operations:
```javascript
const numbers = [1, 2, 3, 4, 5];
const doubledNumbers = [...numbers].map(num => num * 2);
console.log(doubledNumbers); // Output: [2, 4, 6, 8, 10]
```
**Performance Considerations**
While the spread operator is convenient, it’s important to be aware of its performance implications, especially with very large arrays. In some cases, methods like `Array.prototype.concat` might offer better performance.
#### Advanced Use Cases with Objects
**Merging Objects**
The spread operator simplifies merging objects, allowing for clean and concise syntax:
```javascript
const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };
const mergedObj = { ...obj1, ...obj2 };
console.log(mergedObj); // Output: { a: 1, b: 3, c: 4 }
```
**Creating Copies of Objects**
Shallow copies of objects can be created easily, similar to arrays:
```javascript
const originalObj = { name: 'Alice', age: 25 };
const copiedObj = { ...originalObj };
console.log(copiedObj); // Output: { name: 'Alice', age: 25 }
```
**Combining with Destructuring**
The spread operator can be combined with destructuring for more advanced patterns:
```javascript
const user = { id: 1, name: 'Alice', age: 25 };
const { id, ...rest } = user;
console.log(rest); // Output: { name: 'Alice', age: 25 }
```
**Performance Considerations**
Similar to arrays, when working with very large objects, consider the performance impact of using the spread operator.
#### Function Arguments
The spread operator can also be used to pass an array as individual function arguments:
```javascript
const numbers = [1, 2, 3];
function sum(a, b, c) {
return a + b + c;
}
console.log(sum(...numbers)); // Output: 6
```
This is particularly useful for variadic functions or when working with libraries that accept a variable number of arguments.
#### Common Pitfalls and Best Practices
**Handling Non-Iterables**
Using the spread operator on non-iterables can lead to errors:
```javascript
const notIterable = null;
try {
const result = [...notIterable];
} catch (error) {
console.error('Error:', error.message); // Output: Error: not iterable
}
```
**Deeply Nested Structures**
The [spread operator](https://www.youtube.com/watch?v=dxQQ1sUOQQI) only creates shallow copies. For deeply nested structures, consider using other methods like `JSON.parse(JSON.stringify(...))` or libraries like Lodash for deep cloning.
**Writing Clean Code**
- Prefer the spread operator for its readability and conciseness.
- Be mindful of performance with large datasets.
- Use it in combination with other modern JavaScript features for more expressive code.
#### Conclusion
The [spread operator](https://qirolab.com/posts/javascripts-es6-spread-operator) is a versatile and powerful tool in JavaScript, enabling developers to write cleaner, more efficient code. By understanding its advanced use cases and best practices, you can harness its full potential in your projects. Whether you’re merging arrays, copying objects, or passing function arguments, the spread operator simplifies many common tasks, making your code more readable and maintainable.

## **Introduction**
Often heard of Llama weights but have little idea about it? Don’t worry! In this ultimate guide, we will explore the concept of weight, discuss the content and the importance of Llama weights, ways of downloading llama weights and the most efficient method of adopting LLMs — — API. So, if you want to keep up with the Llama weight trend, keep reading!
## **Understanding the Concept of Weight**
Weight is a fundamental concept in neural networks, including the transformer-based language models like Llama. Weights are the adjustable parameters that the model learns during training, enabling it to capture patterns in the data and perform well on natural language processing (NLP) tasks. The [transformer](https://blogs.novita.ai/building-the-ultimate-transformer-train/) architecture, which has become the prevalent design for state-of-the-art language models, organizes these weights into a specific structure named “multi-head self-attention”.
In transformer models, the weights are distributed across hundreds of layers, each consisting of numerous neurons or units. The number of parameters varies among models depending on the architectural design choices, such as the number of layers, the dimensionality of the input and output representations, and the complexity of the attention mechanisms.
Substantial parameter count allows the model to capture intricate patterns and nuances in natural language, facilitating its strong performance on a wide range of NLP tasks, from text generation to question answering and beyond. It’s important to note that while a higher number of parameters generally correlates with increased model capacity, efficient utilization of these parameters through architectural innovations, training strategies, and regularization techniques is crucial for optimal performance and generalization.
## **What are Llama Weights?**
Llama weights refer to the parameters utilized in models within the Llama family. The current discussions around Llama weights are a result of Meta AI’s decision to share the Llama 2 and 3 models with the public. This means that anyone can now freely access and download these models, along with their tokenizers (tools that break text into smaller parts called “tokens”, similar to a word) and weights for personal use and even commercial use.
### **Difference between Llama 2 and 3**
Naturally, with the innovation of models, different Llama generations have different weight numbers. To elaborate further, [Llama 2](https://blogs.novita.ai/introducing-llama-2-all-worthwhile-after-llama-3-released-2/) offers models in three different sizes, with approximately 7 billion, 13 billion, and 70 billion parameters respectively. Similarly, the [Llama 3](https://blogs.novita.ai/meta-llama-3-the-most-powerful-openly-available-llm-to-date/) model is available in versions with 8 billion and 70 billion parameters. Although Meta AI’s largest models have over 400 billion parameters, they are still undergoing training and have not yet been released.

5. The lines with `layers.#.attention.wq/wk/wv/wo.weight`: These are the weight matrices used in the multi-head attention mechanism inside each of the 32 transformer layers. For example, `wq` are the weights to create the query vectors, `wk` for keys, `wv` for values, etc. Query vectors enable the network to generate the output sequence while focusing on various segments of the input sequence.
6. `layers.#.attention_norm.weight`: Weight vectors for normalization inside the attention sub-layers.
7. `layers.#.feed_forward.w1/w2/w3.weight`: Weight matrices for the feed-forward sub-layers inside each transformer layer. These apply non-linear transformations.
8. `layers.#.ffn_norm.weight`: Normalization weights for the feed-forward sub-layers.
The sizes show the dimensions of these weight matrices/vectors. For example, `4096 x 4096` means a square matrix of 4096 rows/columns, representing the model dimension.
The `UnquantizedDataType` refers to the data type/precision used to store the weights, like `F16` (half-precision floating point) or `F32` (regular floating point).
So in summary, this is listing out all the different trainable parameters of the large Llama language model across its embedding layers, attention layers, feed-forward layers, normalization components, etc. The sizes correspond to the model’s vocabulary size and dimensionality.

## **Why Do Llama Weights Matter?**
In the world of AI, weights are the invisible gears that keep the machine running smoothly. Think of them as the muscles of a bodybuilder: properly tuned and developed, they make the difference between a flabby novice and a competition-ready champion. Weights determine how the model processes input data, learns from it, and makes predictions. In Llama 3, managing these weights effectively is crucial for several reasons. First, they ensure it can handle complex tasks efficiently without unnecessary computational bloat. Second, well-managed weights lead to better generalization, enabling the model to perform well on unseen data. Third, they contribute to the model’s ability to scale, meaning larger models can be trained and utilized without a proportional increase in computational resources.
It is important to note that Llama weights and other aspects of the model work together to present state-of-the-art performance. Let’s dig deeper into this.

In this article, we will understand the difference between Telos and Solana.
## Telos: A Web3 Blockchain-based Platform
Telos is a third-generation blockchain technology that's frequently used to build cost-effective, scalable, and rapidly built decentralised applications.
Telos made a more collaborative & transparent model by focusing on decision-making and pointing toward influencing and empowering organizations to shift. Thus, the development of the Telos Ethereum Virtual machine (EVM) is to perform that task.
## Telos EVM (Ethereum Virtual Machine)
Taking full advantage of the Telos technology, Telos EVM is fully re-designed and made easier for the developer. It is through which they can develop new or upgrade applications to Telos blockchain applications into the Telos blockchain.
Telos will provide developers with advantages including rapid block times, cost-effective transactions, and equitable distribution. Additionally, it lacks governance, micro transaction deFi, speed and scalability, and front-running.
## Solana
Solana is a blockchain platform that is popular for its efficiency and speed. It pays its transaction fees through its native crypto. Solana has a Smart contracts capability through which developers can build decentralized apps.
Solana focuses on making the crypto network grow faster and faster and is one of the new crypto solutions aimed at making crypto networks faster and more efficient. It implements a series of clever technologies, including a new method called “Historical proof.”
## Telos Vs Solana
**Market Power**
It is among the most important indicators of accessibility, order, and future development and rotation as people utilise technology.
**Programming Languages**
The programming language for Telos Smart contract development is EOSIO C ++ (with Telos Evm — Solidity and Vyper too). Solana, Rust. Although both languages “‹” are popular and well known, we can also add some code comparisons to see which one is most “appropriate’ to develop smart contracts.
**Energy Consumption**
All transactions with blockchain production consume energy and discharge pollution into the environment. For sustainability, reducing energy consumption as much as possible is essential.
**Environmental Friendliness**
In addition to the previous point, it is also important to note whether block manufacturers use renewable energy or not and if there is an organizational policy related to reducing the carbon footprint offset network.
**Divide Rate**
It refers to transferring control and decision-making from a central organization (individual, organization, or group) to a distributed network. It is one of the most important features of blockchain networks.
**Block Time**
It is the amount of time it takes to generate a new block or data file on a blockchain network. It is almost when the transaction takes place. Thus, a short blockade means a quick transaction.
**Developers and Communities**
A crucial factor in the success of a blockchain network is that the community supports it. Developers and the public are generally the backbone of the blockchain and give it value and credibility.
**Transaction Per Second**
A basic statistic called transactions-per-second (TPS) enables the speedy completion of every transaction’s parts. It has a brief latency and reduces latency for dApps.

1,877,812 | Forget the Gym, Benchmark Testing is Here to Pump Up Your Software! | Ever wonder if your software is the Usain Bolt of applications, leaving the competition in the dust... | 0 | 2024-06-05T09:17:05 | https://dev.to/ngocninh123/forget-the-gym-benchmark-testing-is-here-to-pump-up-your-software-38ec | benchmarktesting, productivity, metrics, testing |
Ever wonder if your software is the Usain Bolt of applications, leaving the competition in the dust or more like a sloth stuck in molasses? That's where [benchmark testing](https://www.hdwebsoft.com/blog/how-to-perform-benchmark-testing.html) comes in, the ultimate fitness tracker for your program! We're not talking push-ups and crunches, though. We're talking about metrics, baby, the numbers that reveal your software's true potential (or lack thereof). So buckle up because we're about to dissect the funny bone of benchmark testing – the metrics that will make you laugh (or cry, depending on the results 🤥).
**_Prepare to dive into a world of_**:
**Load Times that Move Slower Than Your Grandma's Dial-Up Connection**: We'll measure how long it takes your software to chug through tasks, revealing if users will be reaching for their phones in frustration or actually getting things done.
**Memory Usage that Makes a Hoarder Blush**: Benchmarking will expose your software's appetite for RAM, showing whether it's a lean, mean, memory machine or a bottomless pit of resource consumption.
**Buggy Behavior that Makes a Clown Look Coordinated**: We'll uncover hidden glitches and errors, the unexpected hiccups that turn your software into a comedy of errors (hopefully not for your users!).
So, are you ready to laugh (or maybe cry a little) as we explore the hilarious world of benchmark testing metrics? Let's get this software fitness party started!
## Benchmark Testing Metrics: The Hilarious Report Card Nobody Asked For
Remember those childhood report cards filled with cryptic symbols and vague teacher comments? Well, benchmark testing metrics are like the adult version – except way more technical and potentially funnier (depending on your sense of humor, of course).
### Performance Metrics - Slow is the New Slowpoke
Ah, performance metrics. The bane of developers everywhere (except maybe the ones who wrote the code that calculates them). But fear not, weary coder! Today, we'll delve into the wacky world of these metrics, transforming them from dry data points into a laugh riot (or at least a chuckle... maybe).
Let me introduce the Performance Metric Posse:
**Response Time**: Imagine your software is a grumpy barista. Response time is how long it takes for that grumpy barista to acknowledge your order for a venti latte with oat milk, extra caramel drizzle, and a sprinkle of unicorn tears (because, apparently, that's a thing now).
**Throughput**: This metric measures how many orders that grumpy barista can actually pump out in an hour. Think of it as the barista's high score on a latte-making game – the faster they churn out drinks, the higher the throughput.
**Latency**: This one's like the barista's internet connection. High latency means your order gets lost in the ether, delaying your caffeine fix. Think buffering videos on dial-up – that's high latency (and a recipe for frustration).
By understanding these metrics (and hopefully getting a chuckle along the way!), you can optimize your software and turn that grumpy barista into a latte-slinging superstar. Remember, a happy barista (and a fast app) makes for a happy customer!
### Scalability Metrics: The Three Amigos of Software Stretchiness
Imagine your software is a pair of stretchy pants. You want them to handle a casual Sunday brunch (load capacity), a Thanksgiving feast with all the relatives (peak load), and maybe even squeezing into your old high school jeans for a reunion (elasticity). That's what scalability metrics are all about - figuring out how much your software can handle before it goes from "comfortably stretchy" to "ripped at the seams."
Here's the breakdown of these hilarious metrics:
**Load Capacity**: This is basically the "Sunday Brunch" test. It measures how much your software can handle before things start getting slow and frustrating. Think of it as that awkward moment when you realize you've crammed too many people onto the couch and someone's about to get squished.
** Peak Load**: Picture Thanksgiving dinner. Everyone's hungry, the turkey's enormous, and the software is working overtime. Peak load measures how much your software can handle at its absolute busiest moment. This is where you pray your stretchy pants (software) can accommodate Aunt Mildred's extra helping of mashed potatoes (data).
**Elasticity**: Now comes the real test - can your software be like those amazing yoga pants that somehow fit everyone? Elasticity measures how quickly your software can adapt to changing demands. It's like magically adding more seats to the metaphorical couch (or magically expanding your pants) to accommodate unexpected guests (or data surges).
So, the next time you hear about scalability metrics, remember the image of stretchy pants and all the hilarious possibilities (and potential disasters) they represent!
### The Reliability Report: Your Software's "Oops-I-Did-It-Again" Scorecard
Ah, reliability metrics. The glamorous world of errors, crashes, and those awkward moments when your software decides to take a permanent vacation. But hey, at least it's honest, right? Here's the breakdown of your software's "Oops-I-Did-It-Again" report card:
**Error Rate**: This metric tracks how often your software throws a tantrum and throws an error message at your users. Imagine it as a "clumsy meter" - the higher the number, the more likely your software is to trip over its own code and faceplant.
**Mean Time Between Failures (MTBF)**: This fancy term basically translates to "how long between meltdowns?" Think of it as the software's "reliability streak." A high MTBF means your software can go long stretches without throwing a wrench into the works. A low MTBF... well, let's just say your users might want to invest in some good stress balls.
**Mean Time to Repair (MTTR)**: This metric measures how long it takes your team to fix the inevitable software hiccups. Think of it as the "software ambulance response time." A low MTTR is like having a pit crew of ninjas who can diagnose and fix problems faster than you can say "bug squashed." A high MTTR means your users might be stuck waiting for a fix longer than they waited in line for the new iPhone.
So, how'd your software score on the "Oops-I-Did-It-Again" report card? Don't worry, even the most reliable software has its moments. But by keeping an eye on these metrics, you can make sure your software spends less time embarrassing itself and more time being a rockstar for your users.
### Resource Utilization Metrics: The Three Stooges of Software Performance
Ever wonder how your software handles pressure? Does it gracefully handle tasks like a seasoned waiter at a Michelin-starred restaurant, or does it crumble like a stale cookie under a toddler's grip? That's where resource utilization metrics come in – the wacky trio that tells you how efficiently your software juggles its resources.
Brace yourselves for the hilarious antics of:
**CPU Usage**: This metric is like Moe from the Three Stooges – it measures how much "thinking power" your software is using. Is it working its circuits to the bone, leaving users staring at a spinning beachball, or is it taking a permanent siesta?
**Memory Usage**: Meet Larry, the forgetful one. Memory usage tells you how much space your software is hogging in your computer's RAM. Is it a minimalist, leaving plenty of room for other programs, or is it a packrat, gobbling up every byte it can find?
**Disk I/O**: Imagine Curly, the wild card. Disk I/O measures how often your software accesses the hard drive. Is it constantly thrashing around like a fish out of water, slowing everything down, or gracefully retrieving information when needed?
By analyzing these resource utilization metrics, we can see if your software is a well-oiled machine or a slapstick comedy of inefficiency. Get ready to laugh (or maybe cry) as we unlock the secrets of these hilarious performance indicators!
### Network Metrics: The Hilarious High Wire Act of Your Data
Imagine your internet connection as a circus tightrope walk. Your data, dressed in a tiny clown suit (because why not?), is trying to make it across. But there are some hilarious obstacles in the way:
**Bandwidth**: This is the width of the tightrope. A narrow rope (low bandwidth) means your clown struggles to get by, data gets squished, and things move painfully slow. Picture a tiny poodle trying to cross a tightrope meant for elephants – pure comedy (and frustration).
**Packet Loss**: Think of these as rogue banana peels scattered across the tightrope. Packets are little bundles of information your data is carrying. When packets get lost, it's like the clown trips and some of his juggling pins fall – the data gets messed up, and things might not make sense on the other side.
**Network Latency**: This is the time it takes for the clown to wobble across. High latency is like a tightrope made of Jello—everything slows down to a hilarious crawl. Imagine the clown clinging for dear life, taking forever to inch across. Not ideal for anyone!
So, network metrics are like watching this crazy tightrope walk unfold. By monitoring bandwidth, packet loss, and latency, we can ensure your data gets where it needs to go without any clown-related mishaps (or at least minimize them).
The goal? A smooth, efficient data flow that lets your information perform a flawless trapeze act – impressive and error-free!
## So, You've Pumped Up Your Software with Benchmark Testing... Now What?
Congratulations! You've put your software through its paces and witnessed its digital push-ups and memory crunches. But before you spike the protein powder and celebrate, there's one crucial step: deciphering the results.
Don't worry! It's not rocket science (unless your software is launching rockets, in which case, good luck!). Interpreting benchmark testing results is like reading a fitness tracker – some numbers are good, some are...well, let's just say they might require a trip to the software development gym for some extra reps.
Ready to unlock the hidden meaning behind those hilarious (or maybe tear-jerking) metrics? Head over to our [blog](https://www.hdwebsoft.com/blog/benchmark-testing-metrics-and-interpretation.html), where we'll break down how to interpret those numbers and turn your software into a true champion (or at least get it out of the software equivalent of sweatpants and into some performance gear).

However, the real game-changer came with the introduction of hooks in React 16.8. Hooks allow you to use state and other React features in functional components, making your code more concise and easier to understand.
In this first part of our three-part series on mastering React hooks, we'll delve into the most fundamental hooks: useState and useEffect. By the end of this post, you'll have a solid understanding of how these hooks work and how to use them effectively in your React projects.
_**The Power of Hooks in React**_
Before hooks, managing state and lifecycle methods in React was primarily done through class components. While powerful, class components can be verbose and sometimes harder to manage, especially for newcomers. Hooks brought a new way of thinking about state and side effects, making functional components as powerful as class components but with a cleaner and more intuitive syntax.
Understanding useState
The useState hook is the cornerstone of React's state management in functional components. It allows you to add state to your functional components, enabling them to manage and react to changes in data.
Basic Usage of useState
Here's a simple example to illustrate the use of useState:
```
import React, { useState } from ‘react';
function Counter() {
// Declare a state variable named "count" with an initial value of 0
const [count, setCount] = useState(0);
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>
Click me
</button>
</div>
);
}
export default Counter;
```
In this example:
- We import useState from React.
- We declare a state variable count and a function setCount to update it.
- We initialize count to 0.
- On button click, we update the count using setCount.
_**Using Previous State with useState**_
You can update state based on the previous state by passing a function to the state updater:
```
import React, { useState } from 'react';
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(prevCount => prevCount + 1)}>
Click me
</button>
</div>
);
}
export default Counter;
```
In this example
- setCount receives the previous state prevCount and returns the updated state.
- This approach is useful when the new state depends on the previous state.
_**Using useState with Multiple Variables**_
You can use useState multiple times in a single component to manage different pieces of state:
```
import React, { useState } from 'react';
function UserProfile() {
const [name, setName] = useState('John Doe');
const [age, setAge] = useState(30);
return (
<div>
<p>Name: {name}</p>
<p>Age: {age}</p>
<button onClick={() => setAge(age + 1)}>Increment Age</button>
</div>
);
}
export default UserProfile;
```
In this example,
- we manage name and age as separate state variables, demonstrating the flexibility of useState.
_**Using useState with Objects**_
You can use useState with objects as well, allowing you to manage multiple pieces of state in a single variable:
import React, { useState } from 'react';
```
function UserProfile() {
const [user, setUser] = useState({ name: 'John Doe', age: 30 });
// Function to update user's age
const handleAgeIncrement = () => {
setUser(prevUser => ({
...prevUser,
age: prevUser.age + 1
}));
};
return (
<div>
<p>Name: {user.name}</p>
<p>Age: {user.age}</p>
<button onClick={handleAgeIncrement}>Increment Age</button>
</div>
);
}
export default UserProfile;
```
In this example,
- we manage a user object with name and age properties.
- The handleAgeIncrement function updates the user's age while preserving other properties of the user object.
_**
Basic Usage of useEffect**_
Here’s a basic example of using useEffect to fetch data:
```
import React, { useState, useEffect } from 'react';
function DataFetcher() {
const [data, setData] = useState([]);
useEffect(() => {
// Fetch data when the component mounts
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => setData(data));
}, []); // Empty dependency array means this effect runs once after the initial render
return (
<div>
<ul>
{data.map(item => (
<li key={item.id}>{item.name}</li>
))}
</ul>
</div>
);
}
export default DataFetcher;
```
In this example:
- We import useEffect from React.
- The effect fetches data from an API when the component mounts.
- The empty dependency array [] ensures that the effect runs only once.
_**useEffect with intervals/timers**_
You can control when useEffect runs by specifying dependencies. If a dependency is a state variable, the effect will run whenever that state changes:
```
import React, { useState, useEffect } from 'react';
function Timer() {
const [count, setCount] = useState(0);
useEffect(() => {
const interval = setInterval(() => {
setCount(count => count + 1);
}, 1000);
// Cleanup the interval on component unmount
return () => clearInterval(interval);
}, []); // Empty array means effect runs once
return <p>Count: {count}</p>;
}
export default Timer;
```
In this example:
- The effect sets up a timer that increments count every second.
- The cleanup function clears the interval when the component unmounts.
_**useEffect with Dependency Array**_
The dependency array in useEffect controls when the effect should re-run. If you specify dependencies, the effect will run only when those dependencies change:
```
import React, { useState, useEffect } from 'react';
function DataFetcher({ url }) {
const [data, setData] = useState([]);
useEffect(() => {
fetch(url)
.then(response => response.json())
.then(data => setData(data));
}, [url]); // Effect runs whenever 'url' changes
return (
<div>
<ul>
{data.map(item => (
<li key={item.id}>{item.name}</li>
))}
</ul>
</div>
);
}
export default DataFetcher;
```
In this example:
- The effect re-runs whenever the url prop changes, ensuring that the component fetches data from the new URL
.
_**Handling Infinite Loops in useEffect**_
Be cautious when using useEffect with dependencies. If not handled correctly, you can encounter infinite loops. For example:
```
import React, { useState, useEffect } from 'react';
function InfiniteLoopDemo() {
const [count, setCount] = useState(0);
useEffect(() => {
// This effect will run on every render because count is a dependency
setCount(count + 1);
}, [count]); // Dependency is count
return <p>Count: {count}</p>;
}
export default InfiniteLoopDemo;
```
In this example,
- the effect increments count, but since count is a dependency of the effect, the effect itself triggers a re-render, creating an infinite loop.
- To avoid this, ensure that your dependencies are properly managed to prevent unintended re-renders.
_**Best Practices for useState and useEffect**_
1. Keep State Simple: Avoid deeply nested state objects. Use multiple useState calls instead.
2.
3. Effect Dependencies: Always specify dependencies for useEffect to avoid unnecessary re-renders.
4.
5. Cleanup Effects: Always return a cleanup function from useEffect if the effect creates a subscription or a timer.
6.
7. Use Functional Updates: When the new state depends on the previous state, use a functional update with useState.
_**Conclusion**_
Mastering `useState` and `useEffect` is the first step towards becoming proficient with React hooks. These hooks enable you to manage state and side effects in a more intuitive and concise way compared to class components. In the next part of this series, we'll explore more advanced hooks like `useContext` and `useReducer`, which provide additional tools for managing complex state and context in your React applications.
Stay tuned for Part 2, where we dive deeper into the world of React hooks and unlock more advanced techniques for building robust and scalable applications. Happy coding!

Choosing the right... | 0 | 2024-06-05T09:11:36 | https://dev.to/martinbaun/goleko-vs-other-project-management-tools-listicles-2jfe | programming, productivity, design, architecture | Project management tools offer numerous advantages and simplify your work process. Choosing the right one is vital. Comparing the most popular one to the new rising star will demonstrate this.
## Trello
Trello became synonymous with project management tools. It stepped in to fill an unoccupied position and thrived in the process. The Fog Creek Software development rose in popularity and stature, attracting many users worldwide. It was a beautiful product that was ahead of its time. This attracted buyers, and thus Trello was acquired by Atlassian.
Trello stagnated in some respects and regressed in others under Atlassian. They added bloated features that made Trello susceptible to failures and highly unstable, worsening its user experience (UX) and functionality. Trello users have been left to ponder and complain in community forums.
The available alternatives to Trello weren’t any better. Switching to them would’ve been a sideways move at best. This was the case until recently. Here is a new project management tool designed with the community’s frustrations in mind.
## Goleko
Goleko is the new kid in town ready to change the project management ecosphere. It is a community-inspired alternative for the community by Martin Baun, a software developer who loves developing excellent software. Goleko offers you everything you find in Trello but exponentially improved. It has features the community has been asking for and didn’t know they needed. Goleko is ready to transform what we know of project management tools and change the landscape for the better. Here is how the two compare.
## Goleko vs Trello
## *Simplicity*
Both tools have a simple design and layout. The user interface (UI) is easy to use and navigate. They are designed with good color schemes and navigation layouts, making finding things quick and easy.
Simplicity is vital to [good project management tools](https://goleko.com/). Goleko and Trello have this aspect well included.
Read: *[Practical Tips to Maintain Productivity](https://martinbaun.com/blog/posts/practical-tips-to-maintain-productivity/)*
## *Speed*
Speed is an aspect that’s needed in all project management tools. Page loading times can be overlooked but are very important for improving user experience(UX) and efficiency. Trello takes so much time to load up. This has been the case since the Atlassian takeover. Goleko takes almost no time to load up. There are staggering differences in loading speeds between these two products. This enhances the usability and efficiency of Goleko.
Goleko makes it easy to stay engaged in work. These speeds save time and improve your overall user experience(UX).
## *Stability*
Trello is notorious for losing connection and rendering work you’ve done null. Since the Atlassian takeover, users have complained for so long without any resolution. Connection losses have resulted in the loss of work progress for many users.
Goleko has countered this problem with its *[optimistic lock feature](https://goleko.com/)*. This prevents loss and overriding. Goleko is stable and doesn’t experience random network interruptions. This feature is an additional safety measure. It works in case you experience these technical difficulties on your side.
Goleko values your time, and this feature protects you from losing time and work progress.
Read: *[Tips on starting a startup](https://martinbaun.com/blog/posts/tips-on-starting-a-startup/)*
## *Time Registration*
Time registration isn’t a feature of many project management tools. This has been a massive oversight for many years. Goleko has an integrated time registration feature. This gives you the ability to create detailed invoices on the time-task done. It also allows for proper registration of time in company logs.
The time app displays everything that everyone in the company works on in each project. The app also shows how much money you’re earning and spending on particular projects. This feature is excellent for consultancy work or specific hires. It simplifies time tracking used in a project, money spent, and potential earnings. This is a unique feature of Goleko that adds a new dynamic to work, especially in the case of remote work, making it better than Trello.
## *Integrations*
Goleko lacks an integration feature but has an import feature. This import feature allows you to import all your work, tasks, and projects from another tool to Goleko. You can then comprehensively work on and complete all tasks within Goleko.
Trello has an integration feature but lacks an import feature that seamlessly transfers the projects and tasks.
## *Multi-projects*
Goleko has a multi-project overview. This is made possible via its Smart Board and Activities apps, which allow you to *[see all tasks or activities from every project in one place](https://goleko.com/)*. This feature improves the user experience (UX) and user efficiency. Finding tasks and seeing everything done on a project is fast and easy. This allows for easy tracking of the progress of tasks being done.
Trello lacks a multi-project overview system. This means you cannot view all projects simultaneously. You’ll have to view each project separately and thus spend a lot of time tracking the progress of different aspects of the project. This reduces efficiency, hence making it hard to navigate.
Read: *[Boost Productivity With Checklist](https://martinbaun.com/blog/posts/boost-productivity-with-checklist/)*
## *Screen recording as comments?*
Goleko has a *[screencast feature](https://goleko.com/)*, allowing video recording. You can record videos within the project management tool and give feedback in video format that makes it easy to follow. You can also use the video feature to record progress on a task, giving video feedback to everyone involved.
Trello lacks this unique feature. This feature is unique to Goleko and improves the user experience of the community, making their work simple and more efficient. This screencast Recording feature is a novel feature that proves Goleko is for the community and by the community.
## Conclusion
Goleko is new, fast, and efficient. It is built to serve the community and transform what was thought possible for project management tools. Trello had been the standard for project management tools but fell off. Other project management tools sprung up but were severely deficient.
Goleko has taken the concepts Trello unearthed, improved them, and innovated new ones. Visit Goleko today and start managing all your projects simply and easily.

---
Proceeding with the appointments with the [PnP React controls](https://pnp.github.io/sp-dev-fx-controls-react/) today I want to talk about the **DragDropFiles** control.
You can find the code of this sample [here on GitHub](https://github.com/GuidoZam/blog-samples/tree/main/pnp-react-controls/drag-drop-files).
* * *
The **DragDropFiles** control is a very helpful one which enables the user to drag and drop files into a specific area of the page, in the sample I’ve created a simple control:
This control allows, thanks to the **DragDropFiles** control, to drag and drop files:
Once the files are dropped a list will be populated allowing the user to, for a sample purpose, download the single file or to remove it from the list:
## Show me the code
To use the PnP React controls first you need to install the package:
```
npm install @pnp/spfx-controls-react --save --save-exact
```
After the installation of the package you can proceed with the following instructions for the **DragDropFiles** control.
* * *
You can import the control as following:
```
import { DragDropFiles } from "@pnp/spfx-controls-react/lib/DragDropFiles";
```
The **DragDropFiles** control can be instantiated as following:
```
<DragDropFiles
dropEffect="copy"
enable={true}
onDrop={(files: File[]) => {
// Add the file to the state
this.setState({
files: this.state.files.concat(files[i])
});
}}
iconName="Upload"
labelMessage={strings.DropMessage}
>
{strings.DropLabel}
</DragDropFiles>
```
The main property of this control is the **onDrop** property which returns the dropped files and enable the handling for those files, in the sample the files will be added to the state to be shown in the list of files.
If needed it’s possible to retrieve the content of each file using the async method **arrayBuffer** , in the sample I used the method to enable the download of the selected file from the list of files but it can also be used to parse the dropped files and upload those, for example, in a SharePoint list.
Apart the **onDrop** method there are some available customization to the control, such as:
- the icon shown in the drop area through the **iconName** property, this value is the name of the icon from the [Fluent UI icon set](https://www.flicon.io/).
- the message text shown when dragging the files is the value set to the **labelMessage** property.
- the label shown in the sample for the control is the string set as content of the control, it can also contains other controls or HTML elements, in that case the drop area will be all the component/s inside of the control.
The **dropEffect** property accept values of the data transfer drop effect, those values define the feedback given to the user during a drag and drop operation, if you’re wondering what are the possible values you can find them [here](https://developer.mozilla.org/en-US/docs/Web/API/DataTransfer/dropEffect).
## Conclusions
The **DragDropFiles** control is a quick and easy way to create a drag and drop area in your application, it may be not fully customizable but it surely is an easy and convenient way to allow users to drag and drop files.
Hope this helps! | guidozam |

Backtesting is the most different place between quantitative trading and traditional trading. According to the real market data that has happened in history, the simulation strategy signal triggers and matches the transaction quickly, and the performance report and other data are obtained for a period of time. For domestic and foreign stocks, commodity futures, foreign exchange and other markets, the backtesting is the most important components of strategy development.
## The meaning of backtesting
In the previous chapters, we learned the basics of the mainstream programming language, and taught you how to use these programming foundations to write some simple trading strategies. It can be said that the road has gone by more than half. However, once a strategy is written, which still has a long distance to the real market environment. It also requires constant backtesting —debugging— backtesting —debugging—and so on, until the strategy can fully implement the model content and running smooth.
From the perspective of quantitative trading logic, A trading strategy is actually based on a series of cognitions and assumptions of the market. Backtesting can determine whether these assumptions are stable or not. In historical times of instability, it could bring what kind of loss? as well as to prevent decision-making of these losses.
In addition, from the perspective of quantitative trading operations, back testing can help detect bugs in the strategy logic, such as future functions, Slipping price, multi-degree fitting, and so on. Provide reliable evidence that the strategy can be used for real market trading.
- Verify the accuracy of the trading signal.
- Verify that the trading logic and your ideas are feasible .
- Discover defects in the trading system and improve the original strategy.
So, the meaning of backtesting is preforming an as true as possible trading process, verifying the validity of historical data, avoiding costly mistakes for the wrong strategy, help us filter, improve and optimize trading strategies.
## Backtesting Trap
- The trap of "Trading signal unstable"
The trading strategy is based on static historical data during the backtesting, but the data of the real trading is dynamic. For example: If the highest price is greater than yesterday's closing price, open long position. This open position conditions in real market, if K line has not been completed, then the highest price is dynamic, trading signals is likely to flicker back and forth. During the backtesting, the backtesting engine is based on static historical data that can be simulated and synthesized.
- The trap of the "Future function"
The future function uses the future price, which means that the current conditions may be modified in the future, and the same future function can also cause the trading signal unstable, such as the "zigzag indicator"
As shown below: The zigzag indicator function indicates the turning point of the peaks and troughs. It can adjust its own value according to the latest real-time price, but if the current price changes, the result of the zigzag turning function will also change. If you use this indicator with such future function, the current order signal may be set up and placed, but this signal may not be quantified later.
- The trap of the "Stealing price"
The so-called "Stealing price" behavior refers to the use of past prices to trade. For example: If the highest price is greater than a certain fixed price to open position by using the opening price. This opening position condition is "stealing price", because in the real market, when the highest price is greater than a certain price, the price may have been higher than the opening price of a certain distance, and then use the opening price to open position is impossible. However, in the backtesting environment, you can hypothetically open position at the opening price.
There is also another case where if the price gaps jumps over the fixed price set by the strategy, in the backtesting environment, the trading signal will occurs and can be executed; but in the real market, it obviously can't be executed.
- The trap of the "Impossible trading price"
"Impossible trading price" can be divided into several cases:
first type: In the real market, some exchanges has the daily limit of maximum price raise and falling restriction. However, in the backtesting environment, it is possible to execute the orders.
Second: the exchange orders matching mechanism, which are price priority and time priority. Some varieties of the market order depth will often have a huge number of orders waiting for execution. In the real market, you have to wait orders that before your placing to execute, sometimes your order will never be executed. But in the backtesting environment, the pending order will be execute at any price without waiting.
Third: For arbitrage strategies, the backtesting profit usually are very high, because each time the backtesting operation has been assumed to have grabbed all those spread prices. Under real circumstances, most prices are impossible to execute, or sometimes only one direction or one trading target of trading action is executed, in general, it is almost certainly the conducive direction or trading target will first be executed, then you have to immediately try to execute the opposite direction or variety of the arbitrage strategies orders. even with such short period of delay, the spreads of this trading opportunity may has cost you more than 1 or 2 price points, while the whole spread arbitrage strategy only got very few price points of profit. This kind of situation is very hard to backtest in the simulation environment. Real profits are far away from backtesting results.
Fourth: The "Black swan" event. As shown the red circle in the following figure, the Swiss franc in foreign exchange black swan event, although on the surface there are opening price, highest price, lowest price and closing price. in fact, such extreme market situation come with a k line that its most part are vacuum, lots of stop-loss orders causes the stampede event, the liquidity are almost zero, for orders to execute is very difficult, but in the backtesting environment, it is possible to stop loss.
- The trap of the "Over-fitting"
Every time I saw the following picture, both my heart and mind are amused. this picture shows us a truthful meaning, a ridiculous model, just complex enough, is perfectly adapted to any data.
For quantitative trading, backtesting is based on historical data, but the sample of historical data is limited. If there are too many parameters of the trading strategy, or the trading logic is too complicated, the trading strategy will adapt too much to the historical data.
The modeling process of the quantitative strategy is essentially a process of finding local non-random data from a large number of seemingly random data. If you do not rely on statistical knowledge, it is easy to fall into the trap of overfitting.
So don't deceive yourself. If you find a bad performance data outside the sample, don't feel pity or unwilling to admit that the model does not work, and continue optimizing it until the sample data outside also performed as good as inside. it eventually will injure your real money.
- The trap of the "survivor bias"
Wall Street has a popular joke: Suppose there are 1,000 monkeys in the market who participated in the investment. In the first year, 500 monkeys were lost to the market. Halfway through the second year, there are 250 monkeys left . By the end of the third year, there are 125 monkeys left .
..........
In the ninth year, the last monkey was left. Then you look at it, the more you look at it, the more you feel its face familiar. Finally, you saw the cover of a financial magazine and shouted "Hey, is that Warren Buffett?”
although this is just a joke, you can still mapping it to the real world situation. For example, if there are 1000 fund managers, after 10 years, about 10 fund managers will outperform the market for 10 consecutive years. This may caused by the random luck and decisions, these fund managers' skill has nothing to to with it.
Like the backtest report below, most investor will choose the figure on the left. which has a very solid performance without significant retracement.
but please hold on, as shown on the right, which is the real situation. The curve on the left is only the best one among these many backtests. That is to say, there are many much worse performance than the left situation.
- The trap of the "impact cost"
In a real trading environment, prices are always fluctuating. When you are optimistic about a trading opportunity, the price may have changed at the moment of placing an order. So the slippage problem, whether in subjective trading or in quantitative trading, is inevitable.
But backtesting is based on static data, it is difficult to simulate the real trading environment. For example: the order price is 1050 to buy, but the actual trading price may be 1051. There are many situations for this phenomenon, such as: liquidity vacuum in extreme price movement, network delay, hardware and software systems delay, server response delay, etc.
**Backtest without slippage**
As shown above, is a backtest report without slippage, profit curve looks good, but there are differences between the backtest and the actual trading in real market. Therefore, in order to reduce this error during backtest, we added two slippage point, to increase or decrease the buying and selling price.
**Backtest with slippage**
As shown above, the same strategy, if added with 2 point of slippage, backtesting results with and without slippage are very different, which means that this strategy needs to be improved or abandoned. In particular, the strategy of relatively high trading frequency, adding 1~2 points slippage during backtesting can make the backtesting closer to the real trading environment.
## To sum up
Some people may ask, since there may be so many problems in quantitative trading, how can I prove that my strategy is ok? The answer is simple, we must first simulation trading by this strategy some time before using the real money, if the trading price and trading simulation situation are almost the same with the strategy logic, then it at least prove the strategy logic has no problem.
In any case, for an experienced trading system developer, backtesting is a must thins. Because it can tell you whether a strategy idea can be validated in the historical data. But many times backtesting does not mean that the future will be profitable. Because there are too many pits in the backtesting, after you pay "the price", you will understand it. And these lessons are all piled up in real money. This article is mainly for reduce the detours and traps.

1,877,797 | How Private Equity Firms Operate: A Comprehensive Overview | Private equity firms are a pivotal component in the financial landscape, raising capital from... | 0 | 2024-06-05T08:55:07 | https://dev.to/linda0609/how-private-equity-firms-operate-a-comprehensive-overview-8ha | Private equity firms are a pivotal component in the financial landscape, raising capital from institutional investors such as pension funds and insurance companies. These firms guide corporations in their fundraising efforts and manage a substantial portion of global assets, exceeding 4 trillion USD. The impressive return on investment (ROI) makes private equity an attractive option for many investors. This article will delve into the workings of private equity firms, their investment strategies, and the significant role they play in the business world.
What is a Private Equity Firm?
Private equity (PE) refers to investments made in companies that are not publicly traded. By offering investors partial ownership, private equity allows companies to enhance their financial capacity. Additionally, [private equity services](https://www.sganalytics.com/investment-research/private-equity-and-venture-capital) can assist publicly listed companies in becoming private by acquiring all existing shares and replacing previous owners.
Private equity firms employ professional teams who focus on market trend analytics, often outsourcing investment research to create comprehensive reports. These reports outline the benefits and risks associated with various portfolio management decisions, providing valuable insights for informed investing.
How Private Equity Works
Investing in private equity is generally riskier than traditional investment avenues, necessitating the use of tested investment strategies to mitigate these risks. Experienced fund managers leverage investors’ capital to identify private equity opportunities that promise high ROI.
Private equity firms typically charge a management fee of around 2% of assets under management. Alternatively, they might take 20% of the gross profits if significant structural changes occur in company ownership.
Roles in Private Equity Firms
Private equity firms consist of two main types of partners: general partners (GPs) and limited partners (LPs). LPs are passive investors who do not influence company decisions or policies. In contrast, GPs have the authority to make managerial and executive decisions, directly impacting the company’s operations and strategies.
Investment Research and Networking
[Investment research outsourcing](https://www.sganalytics.com/investment-research/) plays a crucial role in private equity firms, facilitating connections with a broader network of investors and optimizing strategies across various industries. Each investor can also contribute to a company’s financial growth by providing mentorship and strategic advice, thereby enriching the company’s knowledge base and operational efficiency.
Types of Private Equity Investment Strategies
1. Venture Capital
[Venture capital](https://www.sganalytics.com/blog/top-venture-capital-trends) (VC) is a subset of private equity that focuses on providing financial assistance to startups. These young companies often need capital to launch their products and services or expand production capabilities. Venture capitalists not only offer financial support but also bring valuable business management intelligence and industry connections.
Venture capitalists often have a personal interest in the startups they invest in. They use private equity services to assess investment decisions and the growth potential of new companies, which helps in risk mitigation. By sharing their knowledge and experience, venture capitalists can significantly enhance the efficiency and effectiveness of startup teams.
VC investments typically range up to 10 million USD per startup. This approach helps balance the risks, as successful investments in high-performing startups can offset the potential losses from less stable ventures.
2. Leveraged Buyouts
A leveraged buyout (LBO) involves using borrowed capital to acquire a company. The assets of the target company serve as collateral for the debt, enabling private equity firms to make acquisitions without committing significant amounts of their own capital.
The LBO strategy is particularly useful when privatizing public enterprises. By reducing regulatory obligations and increasing operational flexibility, private equity firms can implement policies that make the acquired company more efficient and marketable. This approach often involves dividing the company into smaller, more focused segments, which can simplify the process of selling parts of the company to settle debt obligations.
Many private equity firms utilize multiple rounds of leveraged buyouts to acquire and manage new companies. While the borrowed money incurs interest, the ROI from well-managed companies can easily cover these costs.
Benefits of Private Equity
Private equity offers numerous advantages to both companies and investors. For companies, private equity provides essential financial resources for expansion and operational improvements. Moreover, the expertise and mentorship from experienced investors can lead to significant managerial and strategic enhancements.
Financial Assistance
Private equity firms supply the necessary capital for companies to pursue growth opportunities, whether through expansion, product development, or market entry. This financial support can be crucial for companies that may not have access to traditional financing options.
Managerial Mentorship
Beyond financial assistance, private equity firms bring a wealth of knowledge and experience to the companies they invest in. General partners, who are actively involved in company decisions, often provide strategic guidance that can lead to improved business practices and operational efficiencies. This mentorship can be particularly valuable for startups and companies undergoing significant transitions.
Conclusion
Private equity is a powerful financial instrument that enables businesses to raise capital and gain strategic insights from seasoned investors. By offering partial ownership, private equity helps companies enhance their financial capabilities and operational efficiencies. Through various investment strategies, such as venture capital and leveraged buyouts, private equity firms can provide substantial benefits to the companies they invest in.

1,877,791 | What is Machine Learning? | Machine Learning (ML) is a subfield of artificial intelligence (AI) that focuses on developing... | 0 | 2024-06-05T08:52:31 | https://dev.to/madhuripatil/what-is-machine-learning-53cl | machinelearning, python, datascience, interview | Machine Learning (ML) is a subfield of artificial intelligence (AI) that focuses on developing algorithms and statistical models that enable computers to perform specific tasks without using explicit instructions. Instead, these models learn patterns from data and find relationship between the output variable and input variable, allowing the systems to make decisions or predictions based on new input data.
### Key Concepts in Machine Learning:
1. **Algorithms**: A mathematical function or formulas for solving a problem. In ML, algorithms are used to find patterns and realtionships in data and make predictions.
2. **Data**: The fuel for ML models. This includes structured data (like databases, spreadsheets) and unstructured data (like images and text).
3. **Training**: The process of feeding data to an ML model function to help it learn the patterns and relationships in the data. The data used in this process is called the training set.
4. **Model**: The output of the training process. A model is a mathematical representation of the patterns learned from the training data.
5. **Features**: Individual measurable properties or characteristics of the data. Features are used as inputs to the model. They also known as variables, and attributes.
6. **Labels**: The output variable or result that the model is trying to predict. In supervised learning, the training data includes both the input features and the corresponding labels.
### Types of Machine Learning:
1. **Supervised Learning**: The model is trained on a labeled dataset, which means that each training example is paired with an output label. Common algorithms include linear regression, logistic regression, support vector machines, and neural networks.
2. **Unsupervised Learning**: The model is trained on an unlabeled dataset, meaning that the system tries to learn patterns and structure from the data without any specific guidance on what to look for. Common algorithms include k-means clustering, hierarchical clustering, and principal component analysis (PCA).
3. **Reinforcement Learning**: The model learns by interacting with an environment and receiving rewards or penalties based on its actions. This approach is often used in robotics, gaming, and navigation.
4. **Semi-supervised Learning**: The model is trained on a dataset that includes both labeled and unlabeled data. This can be useful when acquiring a fully labeled dataset is difficult or expensive.
### Applications of Machine Learning:
- **Natural Language Processing (NLP)**: Language translation, sentiment analysis, and chatbots.
- **Computer Vision**: Image recognition, facial recognition, and object detection.
- **Healthcare**: Disease prediction, personalized treatment plans, and medical image analysis.
- **Finance**: Fraud detection, algorithmic trading, and credit scoring.
- **Marketing**: Customer segmentation, recommendation systems, and targeted advertising.
### Challenges in Machine Learning:
- **Data Quality**: The accuracy of the model heavily depends on the quality of the data.
- **Overfitting**: When a model learns the training data too well, including its noise and outliers, and performs poorly on new data.
- **Underfitting**: When a model is too simple to capture the underlying patterns in the data.
- **Computational Resources**: Training complex models, especially deep learning models, requires significant computational power and time.
- **Ethics and Bias**: Ensuring that models are fair and unbiased, and that they respect privacy and ethical considerations.
In summary, machine learning is a powerful tool that enables computers to learn from data and make decisions with minimal human intervention. It is a rapidly evolving field with applications across various industries and domains. | madhuripatil |
1,877,736 | Amazon Inspector | Inspector is a Vulnerability scanning tool for AWS workloads. Here is an over view from AWS:... | 0 | 2024-06-05T08:52:30 | https://dev.to/aws-builders/amazon-inspector-4fk4 | Inspector is a Vulnerability scanning tool for AWS workloads.
Here is an over view from AWS: https://www.youtube.com/watch?v=viAn4E7uwRU
_Personal note_: In the context of other law-enforcement terms used to name AWS Security services(Detective, Guard etc), Inspector is a bit different. In my country, a police inspector (the inspector that comes to my mind when I hear the title) is a law enforcement officer, who conducts investigations. I would say AWS Inspector is more like the vehicle inspector, who would verify if your vehicle is configured fine and is not causing pollution.
For an instance to be scanned by Inspector, it needs to be a managed instance in SSM, and the below prerequisites need to be met:
- SSM Agent is installed on EC2 and it is running
- The instance has an IAM role with the required permissions to talk to SSM.
- 443 port is open outbound from EC2 instance so it can talk to SSM service.
Steps to follow if your EC2 is not coming as SSM Managed instance: https://repost.aws/knowledge-center/systems-manager-ec2-instance-not-appear
**Types of scanning**
- EC2 scanning - An agent would be installed on the EC2 (SSM Agent) which would scan the EC2 for any vulnerability.
- ECR Scanning - Scan images in ECR
- Lambda scanning - Scan packages used in lambda
- Lambda code scanning - scan code in lambda
For the vulnerabilities found, it will give relevant details like remediation steps, CVSS (Common Vulnerability Scoring System) Score, Inspector score etc which shows how critical this vulnerability is.
**Suppression Rules**
Say you have a web server. Then port 80, 443 being open is expected and you dont want to see warnings for that.
You can create suppression rules to avoid seeing specific vulnerabilities reported.
**Vulnerability Database Search**
Search CVE ID in vulnerability databases to get more info on the reported vulnerability.
**Deep scan of EC2**
In addition to OS packages, application packages would be inspected for vulnerabilities. You can specify which paths you need to be scanned.
**Center of Internet Security (CIS) Benchmark assessments**
Center of Internet Security, offers a suite of security benchmarks that serve as authoritative guidelines for securing IT systems, which are utilized extensively in the industry. On-demand/Scheduled scans can be run with CIS benchmark for specific operating systems. This will select resources based on the tags you specify.
**Export Software BOMS**
Export the Bill of Materials in the software packages analysed by inspector into industry standard formats. These BOMs contain a hierarchical list of all the individual components in a package. This functionality helps to check for vulnerabilities in a system not reachable from AWS.
**Inspector Demo**
**EC2 scanning**
Create an EC2 instance with an older version of Debian (version 10) from the marketplace.
https://aws.amazon.com/marketplace/pp/prodview-vh2uh3o4pdfow#pdp-overview
(This AMI is free to use)
Create a security group allowing traffic from anywhere(0.0.0.0/0) to 22. Attach this security group to the EC2.
SSH into the EC2, then install and start the SSM Agent.
Steps for this: https://docs.aws.amazon.com/systems-manager/latest/userguide/manually-install-ssm-agent-linux.html
Now the vulnerabilities from this EC2 would be detected by Inspector and shown in the console.
Security group with SSH from anywhere will also be detected as a vulnerability.
**Container scanning**
Pull a Debian 10 image from dockerhub and push it to the Amazon ECR.
`docker pull debian:10.0`
How to push to ECR: https://docs.aws.amazon.com/AmazonECR/latest/userguide/docker-push-ecr-image.html
Now vulnerabilities from this docker image would be detected by Inspector and shown in the console. You can look at vulnerability per container repo or by container image.
**Lambda scanning**
Create a lambda with some vulnerabilities. For example, lambda below updates a reserved variable and has an insecure socket connection.
```
import os
import json
import socket
def lambda_handler(event, context):
# print("Scenario 1");
os.environ['_HANDLER'] = 'hello'
# print("Scenario 1 ends")
# print("Scenario 2");
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('',0))
# print("Scenario 2 ends")
return {
'statusCode': 200,
'body': json.dumps("Inspector Code Scanning", default=str)
}
```
Code needs to use runtimes supported by Inspector to be able to scan them. Many times this is not the latest, but the -1 version. For python, it is 3.11 as of writing this article, whereas latest version for lambda is 3.12.
You can check the supported versions here:
https://docs.aws.amazon.com/inspector/latest/user/supported.html
Now the vulnerabilities from the lambda code can be seen in the console.

1,877,730 | Separate GitHub Accounts for Work and Personal Projects: A Step-by-Step Guide | Intro We will configure Git to use your work GitHub account and work SSH key for all... | 0 | 2024-06-05T08:48:05 | https://dev.to/nkrumahthis/separate-github-accounts-for-work-and-personal-projects-a-step-by-step-guide-28jk | git, github, softwareengineering, tutorial | ## Intro
We will configure Git to use your work GitHub account and work SSH key for all repositories in your work directory, while using your personal account and SSH key for repositories in other directories.
With this guide you won't have to use weird Github urls or edit your ssh config.
## Requirements
Make sure you have generated ssh keys for your *work* account and your *personal* account.
Let's call them `id_rsa_work` and `id_rsa_personal` respectively.
These instructions are for Mac and Linux. Windows users will have to adapt it.
## Steps
#### 1 Create a config file in your home directory called `.gitconfig-work` and put this in it.
```config
[user]
name = Your Name
email = workemail@company.com
[core]
sshCommand = "ssh -o IdentitiesOnly=yes -i ~/.ssh/id_rsa_work -F /dev/null"
```
- change `Your Name` to your name
- change `workemail@company.com` to your *work* email
- change `~/.ssh/id_rsa_work` to the location of the ssh private key used for your *work* github account.
#### 2 Open your git config at `~/.gitconfig` and put this in it
```config
[user]
name = Your Name
email = personalemail@gmail.com
[core]
sshCommand = "ssh -o IdentitiesOnly=yes -i ~/.ssh/id_rsa_personal -F /dev/null"
[includeIf "gitdir:~/work/"]
path = .gitconfig-work
```
- change `Your Name` to your name
- change `personalemail@gmail.com` to your *personal* email
- change `~/.ssh/id_rsa_personal` to the location of the ssh private key used for your *personal* github account.
- make sure that `.gitconfig-work` is the name of the file you created in the previous step.
## Conclusion
We have set up Git to use your personal GitHub account and personal SSH key as the default for all repositories on your computer, except for those in your work directory, which should use your work account and work SSH key. | nkrumahthis |

```
=spl("=E@p(?.news(~.m(2:);~:T,get(1):S).group(T;~.(S(1)).sort():TS).(T|TS))",A2:D4)
```
As shown in the picture below:
**Explanation**:
The news()function generates multiple records according to a sequence; ~.m(2:) means getting members from the current one ~’s second sub-member to the last one; get(1) gets members on the upper layer loop. E@p() function performs transpose members of the sequence. | judith677 |

1,877,010 | The best free, open-source SaaS template for React & NodeJS | Presenting Open SaaS 🎉 We’re really excited to present Open SaaS, the totally free,... | 0 | 2024-06-05T08:45:02 | https://dev.to/wasp/the-best-free-open-source-saas-template-for-react-nodejs-263 | saas, react, node, fullstack | ## Presenting Open SaaS 🎉
We’re really excited to present [Open SaaS](https://opensaas.sh), the totally free, open-source, production-grade SaaS boilerplate for React, NodeJS, and Prisma.
See it in action here:
{% embed https://www.youtube.com/watch?v=rfO5SbLfyFE %}
Open SaaS has got all the features of those paid SaaS starters you’ve been seeing lately, except its entirely **free** and **open-source**.
**We felt that paying $300-$2,000 for some boilerplate code that you need to manage yourself was crazy**. On top of that, many of these boilerplates rely heavily on 3rd-party services. Add on hosting and other fees, and you’re looking at spending quite a bit of money just to get your idea out there into the world.
**That’s why with Open SaaS we made a conscious decision to try and use open-source and free services whenever possible.** For example, our hosted demo app and its admin dashboard on [OpenSaaS.sh](http://OpenSaaS.sh) are powered by a self-hosted version of Plausible analytics. Want the same features in your SaaS? Well, Open SaaS has got it preconfigured for you!
Also, the [Wasp framework](https://wasp.sh), which Open SaaS uses, does the job of building out a number of features for you, like Auth and Cron Jobs, so that you don’t have to pay a 3rd-party service or code it entirely yourself (we’ll explain this in more detail later).
## What People Are Already Building With Open SaaS...
Since the official release we've had tons of people building amazing apps and launching super creative businesses with Open SaaS. So we though we'd highlight some of them here to start with.
Below is a curated list of some of the apps people from our community:
1. [Solon](https://trysolon.co): An AI sales agent for instagram/whatsapp sellers to help customers with product exploration.
2. [Captn.ai](https://captn.ai): AI agents working together in teams to automate the creation, monitoring, and optimization of Google Ads campaigns.
3. [Bleepify](https://bleepify.me): Automatically dub or remove certain words from videos instantly, with the help of AI. Super helpful for quickly making YouTube videos compliant with their code of conduct.
4. [Get AI Blog Articles](https://getaiblogarticles.com/): A high-quality, SEO-focused blog post generator in markdown format
If these examples above don't already get you inspired to build, continue reading below, where we'll discuss why we built an open-source SaaS template, what stack we used, and how it works.
## Why we built it… and then gave it away for free
The feedback since our official release has been hugely positive.
We've had tons of people rave about it, and numerous SaaS apps already built with it, but we’ve also gotten some questions like:
- “Is it going to stay free?”
- “What’s your motivation for open-sourcing this?”
So we thought we’d go ahead and answer these to start.
First, yes it is 100% free and open-source and will stay that way.
Second, we believe that the collective knowledge of a community of developers, indiehackers, and solopreneurs will produce a better boilerplate than an individual or small group. When you buy a SaaS starter from some developer, you’re already getting an opinionated stack, then on top of that you’re also getting an app built the way they think is best — and that may not always be the best *for you.*
Third, [Open SaaS](https://opensaas.sh) is a project by [Wasp](https://wasp.sh), an open-source React + NodeJS + Prisma full-stack framework with superpowers. We, the Wasp team, believe that Wasp is very well suited for creating SaaS apps quickly and efficiently, and we want this template to prove it. Plus, as developers, we’ve learned so much from other open-source projects, and Wasp itself is an open-source project.
Basically, we love the open-source philosophy and we want to pay it forward. 🙏
So it’s our hope that we can provide a seriously valuable asset to the developer community while spreading the word about our open-source, full-stack framework. And we’d love to see the community contribute to it so that it will grow and become the best SaaS boilerplate out there.
## What Open SaaS is Made Of
We put a lot of hard work into Open SaaS, including the [documentation](https://docs.opensaas.sh), so that developers can get a SaaS app launched confidently and easily.
We’ve also spent some time checking out other free, open-source SaaS starters, and wanted to make sure Open SaaS has all the right features of a production-ready starter, without the bloat. And we think we’ve accomplished that for the most part, although we will continue to add features and improve on it with time.
Here are the main features at the moment:
- 🔐 Authentication (email verified, google, github)
- 📩 Emailing (sendgrid, emailgun, SMTP)
- 📈 Admin Dashboard (plausible or google analytics)
- 🤑 Stripe payments (just add your subscription product IDs)
- ⌨️ End-to-end Typesafety (no configuration necessary)
- 🤖 OpenAI integrated (AI-powered example apps)
- 📖 Blog w/ Astro
- 🧪 End-to-end tests w/ Playwright
- 🚀 Deploy anywhere
- 📄 Full Documentation & Community Support
It’s worth going into some detail about each of these features, so let’s do it.
### Auth
[](https://www.producthunt.com/posts/open-saas)
Thanks to Wasp, Open SaaS ships with a number of possible Auth methods:
- username and password (simplest/easiest for dev testing)
- email verified w/ password reset
- Google and/or Github social login
Here’s where Wasp really shines, because all it takes to set up your full-stack Auth and get pre-configured UI components is this:
```jsx
//main.wasp
app SaaSTemplate {
auth: {
userEntity: User,
methods: {
usernameAndPassword: {},
google: {},
gitHub: {},
}
}
}
```
Seriously. That’s it!
Just make sure you’ve set up your social auth and have your API keys, as well as your `User` and `ExternalAuth` entities defined, and you’re good to go. And don’t worry, that part is all documented and explained in detail in the [Open SaaS Docs](https://docs.opensaas.sh).
On top of that, Open SaaS comes preconfigured with some examples on how to customize and create some really powerful auth flows.
### Admin Dashboard & Analytics
[](https://www.producthunt.com/posts/open-saas)
By leveraging [Wasp’s Jobs feature](https://wasp-lang.dev/docs/advanced/jobs), Open SaaS pulls data from Plausible’s or Google’s Site Analytics (your choice!) and Stripe’s Data APIs every hour and saves them to our database. This data is then shown on our Admin Dashboard (go to [OpenSaaS.sh](https://OpenSaaS.sh) to see it in action). The nice part is, to get access to this data for your own app, all you have to do is follow our guide on getting your analytics API keys, insert the provided script, and you’re good to go!
Again, Wasp makes this whole process really easy. With the function for querying the APIs and getting the data we need already defined for you, Open SaaS then uses a Wasp Job within the `main.wasp` config file:
```jsx
job dailyStatsJob {
executor: PgBoss,
perform: {
fn: import { calculateDailyStats } from "@server/workers/calculateDailyStats.js"
},
schedule: {
cron: "0 * * * *"
},
entities: [User, DailyStats, Logs, PageViewSource]
}
```
And that’s it! Wasp takes care of setting up and running the cron job for you.
### Stripe Payments
[](https://www.producthunt.com/posts/open-saas)
If you’re a developer that’s never built your own SaaS before, then integrating with a payments processor like Stripe is probably one of the few challenges you’ll face.
This was the case for me when I built my first SaaS, [CoverLetterGPT.xyz](https://coverlettergpt.xyz). That was actually one of my main motivators for building it; to learn how to intergrate Stripe payments into an app, as well as the OpenAI API.
And even though Stripe is well known for having great documentation, the process can still be daunting. You have to:
- create the correct product type
- set up webhook endpoints
- tell Stripe to send the correct webhook events to you
- consume the events correctly
- deal with recurring and failed payments
- test it all correctly via the CLI before going live
That’s why having Stripe subscription payments set up for you is such a win.
But even more important than that, is having the whole process conveniently documented for you! Which is why Open SaaS offers you convenient [Stripe guides in our documentation](https://docs.opensaas.sh) 🙂
[](https://www.producthunt.com/posts/open-saas)
### End-to-End Typesafety
Open SaaS was built with Typescript, and because it’s a full-stack app, type safety from the back-end to the front-end can be a real lifesaver. I mean, some [opinionated stacks](https://create.t3.gg/) have gotten hugely popular on this basis.
Luckily, Wasp gives you end-to-end Typesafety out-of-the-box (nothing to configure!), so it was easy for Open SaaS to take advantage of it.
Here’s an example:
1. Make Wasp aware of your server action:
```tsx
// main.wasp
action getResponse {
fn: import { getResponse } from "@server/actions.js",
entities: [Response]
}
```
2. Type and Implement your server action.
```tsx
// src/srever/actions.ts
type RespArgs = {
hours: string;
};
const getResponse: GetResponse<RespArgs, string> = async ({ hours }) => { }
```
3. Import it and call it on the client.
Client-side types will be inferred correctly!
### AI-powered Example App (w/ OpenAI API)
[](https://www.producthunt.com/posts/open-saas)
AI is making new app ideas possible, which is partly why we’re seeing a resurgence in developer interest in creating SaaS apps. As I mentioned above, the first SaaS app I built, [CoverLetterGPT](https://coverlettergpt.xyz), is one of those “GPT Wrappers”, and I’m proud to say it makes a nice passive income of ~$350 MRR (monthly recurring revenue).
I personally believe we’re in a sweet spot in software development where there exists a lot of potential to develop new, profitable AI-powered apps, especially by "indiehackers" and "solopreneurs".
This is why Open SaaS features an AI scheduling assistant demo app. You input your tasks for along with their alotted time, and the AI Scheduler creates a detailed plan for your day.
[](https://www.producthunt.com/posts/open-saas)
Under the hood, this is using OpenAI’s API to assign each task a priority, and break them up into detailed sub-tasks, including coffee breaks! It’s also leverages OpenAI’s function calling feature to return the response back in a user-defined JSON object, so that the client can consume it correctly every time. Also, we're planning on adding open-source LLMs in the future, so stay tuned!
The demo AI Scheduler is there to help developers learn how to use the OpenAI API effectively, and to spark some creative SaaS app ideas!
### Deploy Anywhere. Easily.
A lot of the popular SaaS starters out there use hosting-dependent frameworks, which means you're stuck relying on one provider for deployments. While these can be easy options, it may not always be the best for your app.
Wasp gives you endless possibilities for deploying your full-stack app:
- One-command deploy to [Fly.io](http://Fly.io) with `wasp deploy`
- Use `wasp build` and deploy the Dockerfiles and client wherever you like!
The great thing about `wasp deploy`, is that it automatically generates and deploys your database, server, and client, as well as sets up your environment variables for you.
Open SaaS also has built in environment variable and constants validators to make sure that you’ve got everything correctly set up for deployment, as well as deployment guides in the docs
[](https://www.producthunt.com/posts/open-saas)
In the end, you own your code and are free to deploy it wherever, without vendor lock-in.

https://ovdss.com/apps/json-view-online
In the world of web development and data interchange, JSON (JavaScript Object Notation) has emerged as a standard format due to its simplicity and ease of use. As developers and data analysts frequently interact with JSON data, tools that allow easy viewing and editing of JSON files are invaluable. One such tool is the JSON View Online. This blog post delves into what JSON View Online is, its benefits, and how to effectively use it.
What is JSON?
Before diving into JSON View Online, it's essential to understand what JSON is. JSON is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It is primarily used to transmit data between a server and a web application as text. JSON is language-independent, making it a universal tool for data representation in various programming languages.
What is JSON View Online?
JSON View Online is a web-based tool designed to help users visualise, edit, and validate JSON data. It transforms raw JSON data into a readable and structured format, allowing developers and data analysts to work more efficiently. This tool is particularly useful when dealing with complex JSON structures, enabling quick debugging and analysis.
Benefits of Using JSON View Online
1. Enhanced Readability
One of the main advantages of JSON View Online is its ability to format JSON data into a readable structure. It indents and organises the data hierarchically, making it easier to understand and navigate through different levels of data.
2. Ease of Editing

At the Ably Realtime Fan Engagement Summit in New York City, industry experts shared valuable insights into the relationship between fan engagement and retention, emphasizing the importance of creating compelling digital experiences and fostering genuine connections.
**In the following video and post [Carlo De Marchis](https://www.linkedin.com/in/carlodemarchis/) ("A guy with a scarf") shares a series of key takeaways from experts - including Xalt, Genius Sports, and more ...**
{% embed https://www.youtube.com/watch?v=snMccGUUZxw %}
One of the key takeaways from the summit was the need to move beyond the traditional focus on reach and embrace engagement as a fundamental strategy.
[Catherine Mullen](https://www.linkedin.com/in/catherine-mullen-3483141/?lipi=urn%3Ali%3Apage%3Ad_flagship3_pulse_read%3BaCinlF6ATvG%2F1eJDXg%2BRDA%3D%3D), co-founder and CEO of [Xalt](https://wearexalt.com/), noted:
> "For about a decade in the industry, all I heard was reach, reach, reach. And now I think brands, rights holders, league streaming platforms are understanding the importance of engagement. Driving engagement is critical to drive retention and reducing churn, which is an issue that we all face in the industry, particularly with live sports."
[Michael Patel](https://www.linkedin.com/in/michael-patel-58855535/), Chief Technology Officer at [Genius Sports](https://geniussports.com/), emphasized the importance of exploring new experiences with fans and understanding how they affect their behavior. He compared the process to the "measure, learn, and optimize" lifecycle in advertising, stating:
> "It seems like an intuitive thing that engaged fans will stay longer, will be more loyal to brands, more loyal to leads themselves, and there's a flywheel of creating the content that they want and then coming back for more of that content."
Digital platforms have revolutionized the way sports organizations connect with their fans, offering unprecedented opportunities for two-way interactions and personalized experiences.
[Ari Evans](https://www.linkedin.com/in/ari-evans/), founder and CEO of [Maestro](https://www.maestro.io/), emphasized the importance of utilizing fan engagement features to create stickiness and measure impact, saying:

Creating compelling content is essential for keeping fans coming back for more. This can include exclusive behind-the-scenes footage, in-depth player interviews, and must-see game highlights. However, successful fan engagement goes beyond simply pushing content to fans. It's about enabling two-way interactions through social media, forums, and even gamification.
[Matthew O'Riordan](https://www.linkedin.com/in/mattoriordan/), CEO and founder of [Ably](https://ably.com/), noted:
> "Fans want to experience things with their friends, with their other fans, with people they share things with. And if you're driving delivering platforms and experiences that fans can engage with other fans in more meaningful ways, they come back because they want to experience that again."
Rewarding fans for their engagement is another crucial aspect of retention. [Vishal Parikh](https://www.linkedin.com/in/vishalparikhdigital/), Chief Product Officer at [LiveLike](https://livelike.com/), emphasized the importance of providing a positive, interactive, and engaging experience, stating:
> "It's also important to reward users for their engagement on your platform. They're spending their valuable time from their day on your ecosystem, whether it's on digital platforms or in your venue. And so it's important to consider rewards that increases retention, LTV monetization opportunities, et cetera."
[Simon Gershey](https://www.linkedin.com/in/gershey/), CTO at [Simplebet](https://www.simplebet.ai/), emphasized the critical role of fan engagement in building an ecosystem around sports and interests in sports. He noted that SimpleBet has focused on this challenge for years:
> "Fan engagement's obviously a very critical part of building an ecosystem around sports, around interests in sports. Retaining fans or building a fan base becomes super critical for anyone."
Gershey mentioned that SimpleBet concentrates on creating in-play gaming experiences that can be delivered through betting operators or social media channels to help build and grow a fan base, which is essential for any retention strategy.
Advanced data analytics also play a significant role in personalizing the fan experience.

1,874,841 | What is SaaS? How to Plan, Build, and Launch Your Own SaaS | Introduction You may have heard the phrase "SaaS" thrown about in today's digital environment.... | 0 | 2024-06-05T08:31:11 | https://dev.to/abdul-haadi/what-is-saas-how-to-plan-build-and-launch-your-own-saas-b0k | saas, webdev, learning, developer | **Introduction**
You may have heard the phrase "SaaS" thrown about in today's digital environment. However, what is SaaS actually, and how can one develop their own SaaS?
**What is SaaS?**
Imagine you want a toy that you really love, but instead of buying the toy and taking it home, you play with it at a special place where the toy is always clean, always works, and you can use it anytime you want. This is kind of like what SaaS is for software. It's like a magical toy store that never closes!
SaaS stands for "Software as a Service." It's a way of delivering applications over the internet, where users can access the software through a web browser without needing to install it on their computers. The software is hosted on a server by the company that made it, and users pay a subscription fee to use it. Think of it as renting a super cool toy instead of buying one.
Now that we have covered this ground, let's move on to discuss how you may design, construct, and introduce your own SaaS platform, drawing on my experience creating an online digital business card platform.
**Planning Your SaaS Product:**
1. Identify a Problem to Solve: Think about a problem that people face and how software can help solve it. For example, with the Online Digital Business Card Platform I worked on, the problem was that traditional paper business cards are easily lost and inconvenient. A digital solution was needed to make exchanging contact information easier and more efficient. Plus, paper cuts are a thing of the past!
2. Research Your Market: Understand who your potential users are and what they need. Look at similar products to see what they offer and what gaps you can fill. For our business card platform, the market included professionals who regularly network and exchange contact information. Basically, anyone who’s tired of carrying around a stack of business cards that feels like a mini deck of playing cards.
3. Define Your Features: List out the features your SaaS product will have. Start with the core functionalities that solve the main problem. For the digital business card platform, key features included card creation, easy sharing via URL or QR code, and profile customization. Make sure to add the features that make users go, "Wow, I didn't know I needed this!"
**Building Your SaaS Product:**
1. Choose Your Technology Stack:
Decide on the programming languages, frameworks, and tools you'll use. For a web-based SaaS like our digital business card platform, PHP and MySQL were chosen for backend development, with HTML, CSS, and JavaScript for the frontend. It’s like choosing the best ingredients for your secret recipe.
2. Develop the Backend:
This is where the core logic of your application lives. It handles data storage, user authentication, and all the heavy lifting behind the scenes. Think of it as the kitchen where all the magic happens – without the mess.
3. Design the Frontend:
The frontend is what users see and interact with. It needs to be user-friendly and visually appealing. For our platform, we focused on making the card creation process intuitive and the profile pages attractive. Basically, it should look so good that users want to show it off like a brand new pair of shoes.
4. Integrate Essential Features:
Incorporate the key functionalities you've defined. For the digital business card platform, this included the ability to create, update, and delete cards, as well as sharing features and analytics. Like adding the toppings on your favorite pizza – it’s what makes it special.
**Launching Your SaaS Product:**
1. Test Thoroughly: Before launching, ensure your product works perfectly. Test all features, fix any bugs, and make sure the user experience is smooth.
2. Set Up Your Infrastructure: Host your SaaS product on reliable servers. Use cloud services like AWS or Azure to ensure scalability and reliability. Think of it as making sure your toy store has enough shelves to keep all the cool toys.
3. Create a Marketing Plan: Promote your product to attract users. Use social media, email marketing, and online ads to reach your target audience. Tell the world why your SaaS is the best thing.
4. Launch and Gather Feedback: When it's all set, launch your product. Keep an eye out for customer comments and keep improving. It's like putting your product into the outside world and then making adjustments based on how much fun people are having with it.
**Conclusion**
Creating a SaaS product like the Online Digital Business Card Platform involves careful planning, development, and marketing. By solving a real problem, choosing the right technology, and focusing on user experience, you can build a successful SaaS product that people will love to use. Remember, the key to a great SaaS product is making life easier for your users with a reliable and accessible online solution. And hey, who wouldn’t want to create the next big thing in the magical toy store of software?
Have an idea? Let's connect and build a SaaS together! Whether you have a vision for a new SaaS product or need help bringing your concept to life, I'd love to collaborate and make something amazing. Reach out, and let's turn your idea into reality!

In my previous [article](https://dev.to/cezar-plescan/level-up-your-angular-code-a-transformative-user-profile-editor-project-part-1-4m1c), I walked you through building an Angular user profile editor. While the initial implementation got the job done, there's always room for improvement. Today, I'm taking the next step in optimizing our form by refactoring the way the validation error messages are displayed.
_**A quick note**: If you're new to this series, you might find it helpful to catch up on the previous article. It'll provide you with the context and foundation you need to fully grasp the concepts I'll cover here_.
If you're new to the concept, _refactoring_ is the process of restructuring existing code without changing its external behavior. So, why bother with refactoring?
The benefits are significant:
- **Enhanced readability**: Refactored code is often more concise and easier to understand, making it simpler for us to maintain and extend the codebase in the future.
- **Improved maintainability**: By identifying and eliminating duplicate code, clarifying responsibilities, and simplifying complex logic, refactoring makes our code less prone to bugs and easier to update.
- **Increased reusability**: Refactoring often involves identifying common patterns and extracting them into reusable components or functions. This saves us time and effort in the long run.
- **Better performance**: In some cases, refactoring can lead to performance optimizations by eliminating redundancies or improving algorithmic efficiency.
In this article, I'll show you exactly how to improve the way error messages are displayed in our form. I'll use step-by-step explanations to make these changes easy to understand. By the end, you'll see how these small tweaks can make the code much better!
## Identifying the current issues
I'll start by examining `user-profile.component.html`. What catches my attention is the amount of logic within the first `<mat-error>` element associated with the _Name_ input field{% embed https://gist.github.com/cezar-plescan/28c87c0a23cdd66de32d428e1b7a4ff2 %}I prefer a more declarative approach. The current code within the element is procedural, with an `if` statement and repeated calls to `form.get('name')`. Additionally, the error messages are explicitly associated with the error codes, making the template less flexible.
I'd like to move this logic outside the template so that the view's main responsibility is simply rendering the content. Any additional logic should be handled elsewhere. This aligns with the software design principle of **Separation of concerns**, allowing the template to focus on presentation and leaving error handling to other components.
My approach is to create an abstraction for the code inside `<mat-error>`, similar to a function, with an input (the form control, `form.get('name')`) and an output (the error message). The question is: how can I generate the appropriate content inside the element based on the form control's state? In Angular, we have two main options: **pipes** and **directives**. Let's explore each implementation, discuss their tradeoffs, and then choose the best option for our context.
## Implement a pipe for displaying form field errors
### Usage of the pipe
I'll start by sketching out how the view could use this pipe, and then I'll work on its implementation. I'll name this pipe **`validationErrorMessage`**, and it will take the form control, `form.get('name')`, as input.
```
<mat-error>
{{ form.get('name') | validationErrorMessage }}
</mat-error>
```
This code passes the `form.get('name')` form control object into the `validationErrorMessage` pipe. The pipe will process this input and return the appropriate error message, which will then be displayed within the `<mat-error>` element. I also need to make sure the pipe handles cases where `form.get('name')` is invalid or has no errors, so it doesn't display anything in those situations.
### Implementing the pipe
This pipe should return the validation error messages of the specified form control. I expect the pipe to update the message when the error changes or clear it when the field becomes valid.
But when is the pipe (re)evaluated? It depends whether the pipe is pure or not:
- if the pipe is **pure**, it is evaluated at every change detection cycle but only when its input changes, which implies a performance optimization;
- if the pipe is **impure**, it is evaluated at every change detection cycle, regardless of its input changes.
Our pipe should run only when the field errors change, so I'll create a pure pipe.
In the code example above, I noticed the pipe input is the form control itself. Since the form control is a single reference and doesn't change along with the errors, I'll pass the form control errors object to the pipe instead:
```
<mat-error>
{{ form.get('name')?.errors | validationErrorMessage }}
</mat-error>
```
**_Note_**: The optional chaining operator `?.` is necessary because the Angular compiler would complain that `Object is possibly 'null'`. This is because there's no guarantee that the `get` method will always return a form control object due to its input parameter, which could theoretically be any string.
Here is the implementation of this pipe:{% embed https://gist.github.com/cezar-plescan/f259510abbe83d36c66220c70d9a5306 %}and the usage in the template:{% embed https://gist.github.com/cezar-plescan/a977c0f69c0a326f0974909b0543da1b %}
The `errors` parameter in the pipe's `transform` method is an object generated by the Angular forms, where the keys represent the error codes. The values could be `true` (generated internally by Angular validators) or the message itself (in our app, generated explicitly by the server). The `Object.entries` method converts the errors object into an array of key-value pairs, allowing us to easily iterate over each error type and its corresponding value.
If the value is a string, the pipe will return it. Otherwise, it will read the error message from the `ERROR_MESSAGES` dictionary. Moreover, if there are multiple error messages (even though in our application this won't be the case), they will be concatenated.
The `ERROR_MESSAGES` dictionary is meant to contain messages for certain error codes and isn't associated with any form fields. These codes are usually generated by validators, like `Validators.required` or `Validators.email` (you can have a look at the code where the `form` object is defined in the component class). Such validators don't generate the error messages themselves; they only indicate the presence of validation errors.
_**Important Note**: This implementation, while effective for displaying error messages in out specific scenario, is not a general solution applicable to all projects. There are scenarios that my solution doesn't cover. I want to highlight that displaying form field errors is a very complex topic if we try to cover every possible scenario. My intention is to improve code quality by presenting this concrete example and applying software design principles when we have to deal with repeated code or some logic that should be moved from its original location._
### Reusing the pipe
Now that the pipe is working for the `name` field, I want to explore how can it be reused for other fields. Since the pipe is designed to be generic, I can easily apply it to the `email` field as well: {% embed https://gist.github.com/cezar-plescan/ecf6b9e69119fd280494fa3809f89611 %}To accomodate validation errors for emails, I've updated the `ERROR_MESSAGES` dictionary to include the error for invalid emails: {% embed https://gist.github.com/cezar-plescan/6125eb2cb5ca90296db334c13b776655 %}While this approach works well for simple scenarios, as the form becomes more complex with additional fields and validation rules, we might need a more structured way to manage the error messages. I'll delve into potential solutions for organizing and customizing error messages in the following sections.
### Extending and customizing error messages
There could be situations where we want to display custom error messages for specific fields, instead of the generic ones, or when we have additional form fields. For example, I want to display the message _"Please fill in the name"_, instead of the generic _"This field is required"_ when the name field is empty, and similarly for the email field, _"Please fill in the email"_.
The `ERROR_MESSAGES` dictionary contains pairs of error codes and messages but isn't aware of the fields the errors apply to. While I could theoretically change the dictionary to include the field names, this would tightly couple the pipe to my form fields. If I had another component with different form fields, the dictionary would have to be updated with specific messages for those fields, creating chaos in the code: whenever new forms will be created, the dictionary would need to be updated too, and this reduces the code maintainability, extensibility and scalability.
I definitely want to maintain the pipe's independence from its consumers. How can I do this? I'll pass an additional argument to the pipe with custom error messages for a specific field. And where can I define these messages? To answer this, I first need to address: to which elements do the messages relate? They relate to the form fields. And where are the form fields defined? They are defined in the component. So, I'll create the error messages where the form fields are defined.
Here is the updated template where I pass an argument to the `validationError` pipe:{% embed https://gist.github.com/cezar-plescan/91065bd6a30443c5d4c42a6d1fa3c30a %}I've also added a second parameter to the pipe method for the custom error messages:{% embed https://gist.github.com/cezar-plescan/c9b357147413fff1e5006657729ff5cc %}The custom error messages used in the template are defined in the component class: {% embed https://gist.github.com/cezar-plescan/00d052833e1edfd385250b3e80386b91 %}In addition, I've defined two new types that are used in the pipe and in the component: {% embed https://gist.github.com/cezar-plescan/16a03de0edfd4e303badc5fee60c2e71 %}This approach allows us to easily extend and customize error messages for different fields without cluttering the pipe code or sacrificing its reusability. As our application grows, we can add new fields and their corresponding error messages to the `errorMessages` object in the component, keeping the validation logic organized and maintainable.
### Checking out the code
The code I've described here can be found in the `12.validation-error-pipe` branch of the repository https://github.com/cezar-plescan/user-profile-editor/tree/12.validation-error-pipe.
Feel free to explore the repository and experiment with the code yourself!
## Implement a directive for displaying form field errors
### Usage of the directive
Similar to the pipe implementation, I'll start by defining how I can use a directive to generate error messages within `<mat-error>` elements. This directive, which I'll name `appValidationError`, will be applied directly to the `<mat-error>` element:
```
<mat-error [appValidationError]="form.get('name')?.errors" [customMessages]="errorMessages?.['name']"></mat-error>
```
The directive will have 2 inputs:
- `appValidationError`: the errors object obtained from the form control.
- `customMessages` (optional): custom messages specific to that field.
The directive will then be responsible for dynamically generating and displaying the appropriate error message based on the input values. It will also handle cases where there are no errors or the form control is invalid.
Let's now dive into the implementation details of this `appFieldErrors` directive.
### Implementation of the directive
When using a pipe, we explicitly control where its output is rendered using the interpolation syntax. However, with a directive, we adopt a more declarative approach. The directive takes full responsibility for generating and displaying the error messages within the element it's applied to.
To manipulate the content of the element, we have to inject the `ElementRef` provider, which gives us access to underlying DOM element. We then use this reference to update the element's content with the generated error messages.{% embed https://gist.github.com/cezar-plescan/be253cc9dd4c2815f2b6ffe142db3e07 %}The logic for generating the error messages within the directive is almost identical to that of the pipe. However, there's one key difference: we need to explicitly tell Angular to update the error messages when any of the input properties change. We achieve this by implementing the `ngOnChanges` lifecycle hook, which detects changes to input properties and triggers the `updateErrorMessage` method to refresh the displayed message.
This differs from the pipe, which is typically pure and re-executes automatically when its inputs change. In contrast, the directive needs the `ngOnChanges` hook to actively respond to updates in its input properties.
The choice between a pipe and a directive often depends on the desired level of control and flexibility. While pipes are simpler and more reusable for basic data transformations, directives offer direct DOM manipulation and fine-grained control over how and where error messages are displayed.
### ERROR_MESSAGES provider
Another major change is how I handled the default error messages. Initially, they were defined in the pipe file, but this posed several drawbacks:
- **Separation of Concerns**: The pipe should primarily focus on error message display logic, not on storing the actual messages. Separating the messages into a dedicated location improves code organization and adheres to the Single Responsibility Principle.
- **Testability**: When error messages are embedded, it becomes harder to unit test the pipe in isolation. We can't easily test it with different sets of error messages without modifying the code.
- **Harder to Manage**: As our application grows and the number of error messages increases, managing them within the pipe file can become cumbersome and clutter the code.
- **Limited Customization**: If we want to modify the error messages for a particular component or use case, we'd have to duplicate the pipe and modify it, leading to code redundancy and potential inconsistencies. Additionally, having the error messages tightly coupled to the pipe makes it difficult to use the pipe in different parts of the application with varying error message requirements. If multiple components or directives define their own sets of error messages, we could end up with conflicting definitions for the same error codes, leading to unpredictable behavior.
To address these issues, we can create an injection token named `ERROR_MESSAGES` and define a provider for it. This allows us to provide different error message dictionaries at different levels of our application, offering greater flexibility and customization. The dictionary itself is defined in a separate file for better organization. I've also created a provider function, `provideValidationErrorMessages()`, for the `providers` array of the application configuration.
This file defines the `ERROR_MESSAGES` injection token and creates a provider function to be registered at the root level of the application:{% embed https://gist.github.com/cezar-plescan/b5c6ff4f0b7895bc74f0ed756609f496 %}In the `app.config.ts` file I've added the previously defined provider function `provideValidationErrorMessages()` to register the error message provider at the root level of the application:{% embed https://gist.github.com/cezar-plescan/e94a8ac5dadfdd66ca2e741c9ba9ac92 %}The default error messages are now defined in a separate file: {% embed https://gist.github.com/cezar-plescan/7e632943d7a8acbdc50b53520260b28d %}This might seem like a lot of code to address the issues mentioned earlier, but it showcases the power and flexibility of Angular's **Dependency Injection** system. This approach allows us to easily manage and customize dependencies throughout our application, making our code more modular, maintainable, and testable.
### Overriding default error messages
If we need to define a different dictionary for the default error messages in a specific component, we'll simply provide another value for the `ERROR_MESSAGES` token within that component's `providers` array: {% embed https://gist.github.com/cezar-plescan/9b0bcc30bc36b49de62d24ec54cc252b %}By doing this, we effectively override the default messages provided at the application level. This allows us to customize the error messages specifically for this component. Angular's dependency injection system will then inject this new set of error messages into the `ValidationErrorDirective` whenever it's used within this component or its children.
### Checking out the code
The code I've described so far can be found in the `13.validation-error-directive` branch of the repository https://github.com/cezar-plescan/user-profile-editor/tree/13.validation-error-directive/src/app. Feel free to explore the repository and experiment with the directive yourself.
### Comparison with the pipe
I want to analyze the directive and pipe approaches to determine which is better suited for our application.
- Directive
- **Strengths**:
- **DOM Manipulation**: Directives directly manipulate the DOM, allowing us to modify the appearance, positioning, and content of the element displaying the error message. This offers greater flexibility for complex error visualizations.
- **Precise Targeting**: We can apply the directive to specific form controls, providing fine-grained control over which elements display error messages.
- **Event Handling**: Directives can easily react to events like focus, blur, or value changes, allowing us to update error messages dynamically as the user interacts with the form.
- **Weaknesses**:
- **Learning Curve**: Directives can be slightly more complex to understand and implement than pipes, especially for developers new to Angular.
- **Tight Coupling (Potentially)**: If not designed carefully, directives can become tightly coupled to the specific DOM structure of our form.
- **Testing**: Unit testing directives can be more involved than testing pure pipes due to their interaction with the DOM.
- Pipe
- **Strengths**:
- **Simplicity**: Pipes are generally easier to understand and use than directives, especially for simple data transformations.
- **Reusability**: Pipes are highly reusable and can be used in various templates and contexts.
- **Testability**: Pure pipes are easier to unit test than directives, as their logic is isolated from DOM manipulations.
- **Angular's Optimization**: Angular's change detection mechanism is designed to optimize the use of pure pipes, potentially offering better performance in some cases.
- **Weaknesses**:
- **Limited DOM Manipulation**: Pipes cannot directly manipulate the DOM, so we'll need additional elements (like <mat-error>) and potentially some conditional logic (e.g., *ngIf) in our template to display the error messages.
- **Less Precise Targeting**: While we can conditionally apply the pipe based on error conditions, it might not be as precise as directly attaching a directive to a specific element.
Which is More Appropriate?
**Pipe**: The pipe is likely the more appropriate choice if our error messages are relatively simple strings and we want to prioritize reusability and ease of use. We can easily apply the pipe to multiple form controls within our template.
**Directive**: We can consider a directive if we need more complex error message displays (e.g., custom styling, conditional formatting, or rich UI elements) or if we need to perform more sophisticated DOM manipulations based on the error state.
The final answer depends on the application needs, but in many cases Angular applications tend to become larger and more complex and my choice would be to go with directives.
Additionally, we can combine both approaches:
- Use the pipe to generate the error message string.
- Use the directive to apply that message to the appropriate element (e.g., a <mat-error> tag) and potentially handle any additional styling or UI logic.
## Using third-party libraries
While the custom directive and pipe I've implemented provide a solid foundation for displaying validation errors, more complex form scenarios might require additional features and flexibility. Thankfully, the Angular ecosystem offers several third-party libraries that that can make handling validation errors in our forms easier. I've found two popular libraries that could be useful:
- [ngx-errors](https://github.com/DmitryEfimenko/ngspot/tree/main/packages/ngx-errors/package): This library provides a declarative way to manage validation errors in your templates. It offers features like:
- simplified syntax: we can define error messages directly within the template using simple directives.
- dynamic error display: it automatically shows and hides error messages based on the validation status of the form controls.
- customization: we can customize error messages for specific error types or create our own error templates.
- [@rxweb/reactive-form-validators](https://www.npmjs.com/package/@rxweb/reactive-form-validators): this library goes beyond basic validation and offers a comprehensive set of validators for various scenarios, such as:
- complex validations: it includes validators for cross-field validation, conditional validation, and more.
- customizable error messages: we can easily provide custom error messages for each validator.
- internationalization (i18n): it supports multiple languages for the error messages.
## Refactoring techniques
### 1. Extract Function/Method
#### Description
This refactoring technique is a fundamental principle in software development aimed at improving code organization, readability, and maintainability. The essence of this technique is to take a section of code within a larger function or method that performs a specific task and move it into its own separate function or method. This new function is given a descriptive name that clearly indicates its purpose.
More details at https://refactoring.guru/extract-method.
#### How to refactor
1. **Identify**: Locate a block of code within a function that represents a cohesive unit of work (e.g., calculating a value, validating input, formatting data).
2. **Extract**: Create a new function and move the identified code block into it.
3. **Replace**: Replace the original code block with a call to the new function.
4. **Name**: Give the new function a clear, descriptive name that accurately reflects its purpose.
#### Benefits
- **Improved Readability**: Breaking down large functions into smaller, more focused functions makes the code easier to understand and follow.
- **Reduced Duplication**: If the extracted code is used in multiple places, this technique eliminates the need to repeat it, leading to a cleaner codebase.
- **Enhanced Testability**: Smaller functions are easier to test in isolation, as you can focus on specific inputs and expected outputs.
- **Increased Reusability**: Extracted functions can be reused in other parts of our application, saving development time and effort.
- **Better Maintainability**: The code becomes more modular, making it easier to modify and update without affecting other parts of the application.
#### Where it was used
- The error message logic was extracted from the template into the pipe and the directive.
- The `getErrorMessage` method has been extracted from the main `generateErrorMessage` method in the directive class. This improves readability and modularity, making the code easier to understand and maintain.
### 2. Replace Conditional with Polymorphism
#### Description
This technique addresses situations where we have conditional statements (e.g., if, else if, switch) that determine the behavior of a piece of code based on the type or properties of an object. The goal is to replace these conditionals with a more object-oriented approach using polymorphism.
Polymorphism allows objects of different classes to be treated as if they were of the same type. By creating a common interface or abstract class and then implementing specific behaviors in subclasses, we can eliminate the need for explicit conditional checks.
More details at https://refactoring.guru/replace-conditional-with-polymorphism.
#### How to refactor
1. **Identify the Conditional**: Locate the conditional statement (or series of statements) that you want to refactor.
2. **Create a Common Interface/Class**: Define an interface or abstract class that represents the common behavior or properties of the objects being tested in the conditional.
3. **Create Subclasses**: For each branch of the conditional, create a subclass that implements the interface or extends the abstract class.
4. **Implement Behavior in Subclasses**: Move the code from each branch of the conditional into the corresponding subclass, implementing the shared method or property defined in the interface/abstract class.
5. **Replace Conditional with Polymorphic Call**: Replace the conditional statement with a call to the shared method or property on the object. The specific behavior will be determined at runtime based on the actual type of the object (polymorphism).
#### Benefits
- **Improved Readability**: Code becomes more concise and easier to understand by eliminating explicit conditional checks.
- **Open/Closed Principle**: The code becomes more extensible. We can add new behaviors (subclasses) without modifying the existing code that uses the interface/abstract class.
- **Reduced Complexity**: Complex conditional structures are replaced with simpler polymorphic calls.
- **Better Maintainability**: Changes to a specific behavior only require modifying the corresponding subclass, leaving other parts of the code unaffected.
#### Where it was used
The **`ERROR_MESSAGES` injection token** is a way that implements a form of polymorphism.
The default provider in our core module provides a default implementation of `ERROR_MESSAGES`. In `UserProfileComponent`, we override this provider, essentially providing a new implementation of `ERROR_MESSAGES` with custom error messages.
The `ValidationErrorDirective` injects the `ERROR_MESSAGES` token. Depending on where it's used, we have a **polymorphic behavior**:
- If used in a component without a custom provider, it receives the default error messages.
- If used in a component with a custom provider, it receives the customized messages.
In `validation-error.directive.ts`, the `getErrorMessage` method doesn't contain any explicit conditionals. Instead, it directly accesses the injected `ERROR_MESSAGES` object, which behaves polymorphically depending on the provider.
This polymorphic behavior is achieved through Angular's dependency injection system, which provides the appropriate `ERROR_MESSAGES` object at runtime based on the component's configuration.
## More to come: Stay tuned for future form enhancements
This refactoring journey has demonstrated how small, deliberate improvements can lead to a more robust and maintainable Angular form. Refactoring is not just about fixing problems; it's about continuously evolving our code to make it more elegant, maintainable, and adaptable.
But there's more to come! Stay tuned for future articles where I'll tackle other refactoring strategies and unlock even more potential in your Angular development toolkit.

## Q2: What is the significance of the python virtual environment ? Give some examples ?
## Q1: Describe the python selenium architecture in detail?
A: The architecture of selenium encompasses several components that work together to perform browser automation efficiently.
1. Selenium WebDriver : It is the core component of the selenium suite. It provides the programming interface to create and execute test scripts that interact with web applications. Web driver communicates directly with the web browser, bypassing the need for a browser specific API.
2. Language Bindings : Selenium supports multiple programming languages through its language bindings. Python is one of the supported languages and the 'Selenium' package provides the necessary bindings for python
3. Browser Drivers: Browser drivers are intermediary components that translate WebDriver commands into browser specific actions
Each browser has its own driver:
>> ChromeDriver for Google Chrome
>> GeckoDriver for mozilla firefox
>> IEDriverServer for Internet Explorer
>> EdgeDriver for Microsoft Edge
>> SafariDriver for Safari
4. JSON Wire Protocol/W3C WebDriver Protocol: Initially, Selenium webdriver used the JSON Wire protocol to communicate between client libraries and browser drivers. The protocol is REST like we service that defines various commands and responses for browser interactions. Recently, Selenium has moved to W3C WebDriver standard, which provides a more standardized and robust way of interacting with browsers
5. Selenium Servers: Selenium server is also known as selenium Grid, is a optional component that allows for parallel execution of tests across different machines and browsers. It acts as a central hub that distributes test scripts to various nodes. This setup is beneficial for running large test suits efficiently and ensuring cross browser compatibility.
6. Test Script Execution Flow : below are the steps
>> Test Script Creation : A user writes test script in python using selenium bindings. This script includes various commands like opening URL. Clicking buttons, entering text and validating results.
>> Initialization : The test script initializes the WebDriver instance for a specific browser (e.g Chrome)
>> Command Execution : The WebDriver sends commands to the corresponding browser driver via the JSON wire protocol or W3C WebDriver protocol.
>> Browser Driver Interaction : The browser driver translates the WebDriver command into browser specific actions using browser automation API's
>> Browser Actions : The browser executes actions and return the result to the browser driver.
>> Response Handling : The browser driver sends the execution results back to the WebDriver.
>> Result Validation : The WebDriver receives the results and test script validates them against expected outcomes .
>> Reporting : The test script can generate reports based on the validation results, indicating the success or failure of the tests.
7. Page Object Model : To improve maintainability and readability of test scripts , the page object model is often used in selenium projects. POM is design pattern where Web pages are represented as classes, and elements on the page are represented as variables within the class. This abstraction layer makes the test scripts cleaner and easier to manage.
8. Integration with Testing Framework : Python selenium can be integrated with various testing framework like 'unitest', 'pytest' or 'nose'
## Q2: What is the significance of the python virtual environment ? Give some examples ?
A: Python virtual environment allows us to create an isolated and independent environment for each python projects, ensuring that the project dependencies and package versions are kept separate from other projects on the same system. This helps in preventing conflict and compatibility issues between different projects with varying package requirements.
## below are the few benefits examples of using python virtual environment
1. Dependency Management: Each project can have its own set of required packages and versions, isolated from other projects. This prevents conflicts when different projects require different versions of the same package.
2. Reproducible Environments: Virtual environments allow us to recreate the exact same environment on different machines or systems, ensuring consistent behavior and reducing the "works on my machine" problem.
3. Testing and Development: Virtual environments are commonly used for testing and development purposes, allowing developers to safely experiment with different package versions or configurations without affecting the system-level Python installation.
4. Deployment: When deploying a Python application, we can create a virtual environment with the exact package dependencies required by the application, ensuring that it runs correctly in the target environment.
The Python virtual environment serves several important purposes
in software development. It allows us to create an isolated and independent environment for each Python project, ensuring that the project dependencies and package versions are kept separate from other projects on the same system. This helps prevent conflicts and compatibility issues between different projects with varying package requirements.
## Examples of using virtual environments:
1. Project-specific Dependencies: we have two Python projects, one that requires Django version 3.2 and another that requires Django version 2.2. By creating separate virtual environments for each project, we can install the required Django versions without conflicts.
2. Experimenting with Packages: If we want to test a new version of a package or experiment with a package that may conflict with our existing setup, we can create a virtual environment, install the package there, and safely test it without affecting your main Python environment.
3. Sharing Environments: If we're collaborating on a project with other developers, we can share the virtual environment configuration (e.g., a requirements.txt file) to ensure that everyone is working with the same package versions and dependencies.
4. Deployment to Production: When deploying a Python web application to a production server, we can create a virtual environment on the server and install the required packages, ensuring that the application runs correctly without interfering with other applications or the system Python.

1,877,720 | Myth or Reality: Can Test-Driven Development in Agile Replace QA? | Test-driven development (TDD) is a cornerstone of agile methodology. It involves creating unit... | 0 | 2024-06-05T08:11:35 | https://jetthoughts.com/blog/myth-or-reality-can-test-driven-development-in-agile-replace-qa-programming/ | agile, programming, tdd, qa | 
[Test-driven development](https://jtway.co/why-and-how-to-use-tdd-main-tips-976b3a6edebb) (TDD) is a cornerstone of agile methodology. It involves creating unit tests before writing the code to ensure functionality and efficiency[[1]](https://www.nan-labs.com/blog/Test-driven-development-agile/). This practice optimizes the development process and seamlessly integrates with agile techniques such as Scrum, extreme programming, and agile testing, making it a critical component in achieving built-in quality.
While TDD offers numerous advantages, including increased code coverage and fostering a refactor culture, it raises an intriguing question: Can it replace traditional quality assurance (QA) roles in software development [[1]](https://www.nan-labs.com/blog/Test-driven-development-agile/)? This article delves into the synergy between TDD and QA, exploring how they complement each other in enhancing software quality and facilitating effective collaboration within agile teams [[1]](https://www.nan-labs.com/blog/Test-driven-development-agile/).
## Understanding TDD
Test-Driven Development (TDD) is a disciplined approach to software development that integrates coding, testing (through unit tests), and design (via refactoring). The process is iterative, beginning with creating precise unit tests for functionality before any code is written. This methodology comprises three main phases:
1. **Create Precise Tests**: Developers craft specific unit tests to verify the functionality of particular features, ensuring the code meets requirements and functions as intended [[8]](https://www.browserstack.com/guide/what-is-test-driven-development).
2. **Correcting the Code**: If a test fails, minimal changes are made to the code until it successfully passes upon re-execution [[8]](https://www.browserstack.com/guide/what-is-test-driven-development).
3. **Refactor the Code**: Post successful test execution, the code is examined for redundancy and optimized for performance, enhancing code quality and reliability [[8]](https://www.browserstack.com/guide/what-is-test-driven-development).
TDD's iterative nature fosters an environment where code is continuously tested, ensuring high quality and reducing the likelihood of bugs. It encourages developers to write more straightforward, readable code, reducing unintended side effects of changes [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html). However, it's crucial to note that while TDD ensures the code functions as intended, it does not guarantee that it solves the specific business problem [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html).
TDD can be scaled from unit testing to acceptance testing and BDD-style scenarios, demonstrating its flexibility and compatibility with Agile principles. This adaptability allows for applying Agile methodologies to TDD on a granular level, promoting a more efficient and reliable approach to software development [[5]](https://stackoverflow.com/questions/3138194/is-agile-different-from-tdd-if-so-what-are-the-main-differences).
## The Role of QA in Software Development
In the agile software development landscape, the role of Quality Assurance (QA) is multifaceted, ensuring the delivery of high-quality products through collaboration and expertise. Here's how QA integrates within a Test-Driven Development (TDD) environment:
* **Collaborative Efforts for Quality**: QA professionals work closely with developers from the start, defining test cases and ensuring the application meets both technical specifications and business requirements. This partnership is crucial for embedding quality into the codebase and fostering a culture of continuous improvement [[15]](https://firminiq.com/test-driven-development-tdd-and-its-impact-on-quality-assurance-qa/)[[18]](https://rubygarage.org/blog/quality-assurance-teams-in-agile)[[19]](https://www.quora.com/What-is-the-role-of-a-quality-assurance-engineer-in-Agile-Scrum).
* **Enhanced Testing Strategies**: QA's involvement in Agile projects goes beyond traditional testing. They engage in Acceptance Test-Driven Development (ATDD), where test cases are created upfront in collaboration with developers. This approach not only clarifies requirements but also ensures that all functionalities are tested against the business objectives they aim to achieve [[2]](https://www.xoriant.com/blog/extended-role-of-qa-in-test-driven-development-tdd)[[16]](https://www.linkedin.com/pulse/role-qa-strategy-agile-methodology-qa-touch)[[19]](https://www.quora.com/What-is-the-role-of-a-quality-assurance-engineer-in-Agile-Scrum).
* **Prevention and Detection**: QA's role is pivotal in preventing and identifying defects early in the development cycle. By participating in every stage of development, QA teams contribute to a faster feedback loop, enabling developers to make necessary adjustments promptly. This proactive involvement helps maintain the application's stability, reducing overall testing efforts and ensuring that the final product aligns with the client's needs [[16]](https://www.linkedin.com/pulse/role-qa-strategy-agile-methodology-qa-touch)[[18]](https://rubygarage.org/blog/quality-assurance-teams-in-agile)[[19]](https://www.quora.com/What-is-the-role-of-a-quality-assurance-engineer-in-Agile-Scrum)[[20]](https://sqa.stackexchange.com/questions/8057/role-of-quality-assurance-not-testing-in-agile).
QA's integration into the TDD process underscores the importance of a collaborative approach to software development, where quality is built into the product from the beginning.
## Comparing TDD and QA
When comparing Test Driven Development (TDD) and Quality Assurance (QA), it's essential to understand their distinct roles within the software development lifecycle. TDD is a coding practice emphasizing test-first development, where tests are written before the code. This approach ensures that the codebase is continuously tested, leading to higher code quality and reliability [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html). On the other hand, QA focuses on the broader aspect of software quality, encompassing testing and practices aimed at improving the development process and ensuring that the final product meets the user's needs [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html).
* **Purpose and Approach**:
*TDD:* Aims to ensure code functionality and reliability through continuous testing [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html).
*QA: *Focuses on the overall quality of the software, including usability, performance, and compliance with requirements [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html).
* **Collaboration and Tools**: TDD and QA can benefit from behavior-driven development (BDD), which fosters a common understanding among team members and encourages simpler, defect-free code through automated tests. However, BDD still needs to eliminate manual testing, underscoring the complementary nature of TDD and QA [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html).
* [**Agile](https://jtway.co/tagged/agile) Integration**:
While TDD and Agile share similarities, such as the emphasis on flexibility and continuous improvement, Agile encompasses a broader scope, including project management and team collaboration. TDD, focusing on the technical aspects of coding and testing, fits within the Agile framework, enhancing the development process with its rigorous testing discipline [[5]](https://stackoverflow.com/questions/3138194/is-agile-different-from-tdd-if-so-what-are-the-main-differences).
In conclusion, TDD and QA serve different but complementary purposes in pursuing high-quality software development. Understanding and leveraging both approaches can lead to more efficient, reliable, and user-centric software projects [[3]](https://agilepainrelief.com/blog/test-driven-development-is-not-a-quality-assurance-technique.html)[[5]](https://stackoverflow.com/questions/3138194/is-agile-different-from-tdd-if-so-what-are-the-main-differences).
## Conclusion
Through exploring test-driven development (TDD) and quality assurance (QA) within agile methodologies, it becomes evident that both elements serve distinct yet integrative roles in fostering a high-quality [software development lifecycle](https://jtway.co/mock-everything-is-a-good-way-to-sink-b8a1284fb81f).

---
We frequently hear about the importance of creating a multi-tenant application, especially in the context of developing a Software as a Service (SaaS) application.
There is some confusion about the concept of a “multi-tenant app” and the various models used to develop one. In this article, we took a closer look at those terms in a more practical way.
# Understand different tenancy models from a technical point of view
### Single-tenant architecture
Single-tenant architecture is a software or cloud computing model where each customer or tenant has a dedicated instance of an application or service. If we look at the origin of the B2B business model, it starts with each instance of the software serving only one customer or organization.
### Characteristics
- **Isolation:** Each customer or tenant operates in an isolated environment with dedicated resources, databases, and configurations.
- **Customization:** Single-tenant architectures often allow for greater customization and flexibility to meet specific customer needs.
- **Security:** Enhanced security and data privacy, as customer data is not co-mingled with that of other tenants.
- **Scalability:** Scaling resources and capacity can be more straightforward, as each tenant's instance can be adjusted independently.
- **Maintenance:** Independent maintenance and updates, as changes made to one tenant's environment do not affect others.
- **Cost:** Typically higher infrastructure and operational costs due to the need to maintain separate instances for each tenant.
### Examples
- **Dedicated hosting:** Traditional web hosting providers offer single-tenant architectures, where each client gets its own resources, databases, or configurations.
- **On-premises software:** Some enterprise-level software applications, such as customer relationship management (CRM) or human resource management systems (HRMS), offer single-tenant deployment options for organizations with strict data security and customization requirements.
- **SaaS with premium tiers:** In some Software as a Service (SaaS) offerings, premium or enterprise tiers provide single-tenant options for customers requiring enhanced security, compliance, or customization.
Single-tenant architecture is commonly used in scenarios where compliance is paramount or needs tailored security requirements. For example, industries like finance, healthcare, and government, which have strict regulatory requirements, often favor single-tenant solutions to ensure compliance.
However, it's important to note that single-tenant architectures can be more resource-intensive and complex to manage compared to multi-tenant architectures, as each customer's instance requires its own infrastructure and maintenance. As a result, they may be more suitable for applications with fewer but larger customers or where customization and isolation are critical.
## Multi-tenant architecture
> **Software multi-tenancy** is a [software architecture](https://en.wikipedia.org/wiki/Software_architecture) in which a single [instance](https://en.wikipedia.org/wiki/Instance_(computer_science)) of [software](https://en.wikipedia.org/wiki/Software) runs on a server and serves multiple tenants. Systems designed in such a manner are "shared" (rather than "dedicated" or "isolated"). A tenant is a group of users who share common access with specific privileges to the software instance. With a multi-tenant architecture, a [software application](https://en.wikipedia.org/wiki/Application_software) is designed to provide every tenant with a dedicated share of the instance - including its data, configuration, user management, tenant individual functionality, and [non-functional properties](https://en.wikipedia.org/wiki/Non-functional_requirement). -- Wikipedia
### Characteristics
- **Shared resources:** Multiple tenants share the same infrastructure, including servers, databases, and network resources, to optimize resource utilization.
- **Isolation:** Tenants' data and configurations are logically segregated, ensuring data privacy and security.
- **Economies of scale:** Multi-tenancy can be cost-effective as the overhead is distributed among multiple users, reducing operational and infrastructure costs.
-** Scalability:** The architecture can scale horizontally or vertically to accommodate growing numbers of tenants and users.
- **Maintenance:** Updates and maintenance are streamlined, as changes apply uniformly to all tenants, simplifying management.
- **Customization:** While some customization is possible, it is typically more limited compared to single-tenant architectures to maintain system-wide consistency.
### Examples
- **Cloud-based SaaS:** Most Software as a Service (SaaS) applications, such as Google Workspace and Salesforce, employ multi-tenancy to serve multiple organizations or users on a shared platform.
- **Shared hosting:** In web hosting, shared hosting services host multiple websites on the same server, each belonging to a different customer or organization.
- **Public cloud services:** Public cloud providers, such as AWS and Azure, use multi-tenancy to serve diverse clients with isolated virtualized resources within shared data centers.
- **Enterprise-wide infrastructure solutions:** Such as a shared Kubernetes cluster that's used by multiple business units within an organization.
# Redefining multi-tenant apps in the real world
We provided definitions from an architectural perspective, making it straightforward to distinguish between multi-tenant and single-tenant designs. However, this leans more toward the technical definition. If we use these definitions in our real-world development environment when designing tenancy models, this way of thinking assumes that a multi-tenant app must have a purely shared, multi-tenant infrastructure.
However, business and product vary a lot and have lots of case-by-case requirements so there's no one-size-fits-all solution.
Imagine a scenario where a tenant is using resources from a shared infrastructure, but due to specific business needs, they require one or two parts of the system to be exclusively dedicated to them. These dedicated parts could be the database, instances, or a combination of other components, all while sharing the overall infrastructure. This is where the mixed-tenant architecture comes into play.
In practical SaaS product development, it's common to meet a scenario where a product is primarily designed with a generic multi-tenancy model. However, certain aspects of the architecture or resources may be toward a "single-tenancy" approach.
AWS used the following case as an example to communicate this concept: multi-tenancy is a broad concept, and it is case-by-case to combine and choose the right strategy to define what you want to achieve the shared resources and data isolation.
In other words, sometimes people still call this model “Multi-tenancy”, so in the broader definition of multi-tenancy, it doesn't imply that **every** component in a solution is shared. Rather, it implies that at least some components of a solution are reused across multiple tenants.
Understanding this term broadly can better help you empathize with your client's needs and where they come from.
Rather than fixating on a single architectural model, multi-tenancy reflects the practicality of a SaaS product's architecture in the real world. When we refer to a multi-tenant app, it doesn't necessarily mean the app adheres to one architectural model; it might utilize various tenancy strategies, indicating that at least some of its components are shared.
# Key considerations to determine your tenancy model strategy
Here comes the question, how do I propose the tenancy strategy for my product? Here are some important questions to think about:
- What are your business goals?
- Can a single-tenant solution support your future growth plans?
- How big is your operations team, and how much of your infrastructure management can be automated? Do you care about agility and cost efficiency?
- Are your customers comfortable with various multi-tenancy options?
- How does each option impact compliance, both yours and your customers?
- Are you expected to meet service-level agreements (SLAs) or aim for specific service-level objectives (SLOs)?
- Have you considered security, cost, performance, reliability, and responsiveness to individual tenant needs as a whole?
Remember that there isn't a rigid division in your product where you must opt for either a purely multi-tenant or solely single-tenant model. Your decision should be based on how you divide your product's architectural components and the specific isolation levels needed by your customers or business. You can then apply different approaches accordingly.
# Next
We talked about the “new” definition of a multi-tenant app, however, how about tenant isolation, identities, and how to determine whether your identities should be isolated or not? What does it mean for identities to be "isolated"?
The confusion often arises when dealing with situations where one real-world user has two different identities. Is it appropriate to label this situation as - “identities isolated”?
We'll address these questions in our upcoming series of articles. Stay tuned!

1,877,716 | Best practices for optimizing Ruby on Rails performance | Ruby on Rails is a popular web development backend framework based on the famous Ruby language.... | 0 | 2024-06-05T08:09:40 | https://jetthoughts.com/blog/best-practices-for-optimizing-ruby-on-rails-performance/ | rails, ruby, performance, optimisation | 
Ruby on Rails is a popular web development backend framework based on the famous Ruby language. This framework can be used to build all types of web applications and is fast on its own. But when it comes to building enterprise applications, optimizing your code and all related aspects is essential. This article will explain the best practices for optimizing Ruby on Rails performance for your subsequent enterprise applications. But before that, let’s look at why performance optimization is needed.
## Why is Performance Optimization Needed?
### **SEO**
Search engines promote web apps that are highly optimized and [load web pages faster](https://jtway.co/load-web-page-in-less-than-one-second-145bbfecff12) across all devices. When your apps are optimized, your SEO rankings will improve, and you will gain more organic traffic, resulting in higher usage growth.
### **Better User Experience**
A website optimized for performance will load faster than the ones that aren’t. Such websites provide a better user experience as they can provide information quickly and also allow users to navigate between pages faster.
### **Saves Costs**
An optimized web app requires fewer resources to run and efficiently serve incoming requests, which leads to decreased costs and significant savings in hosting and other infrastructure. Moreover, an optimized app also requires fewer resources to scale, so even if the incoming requests increase rapidly, your [cost to build a web app](https://www.esparkinfo.com/blog/web-application-development-cost.html) will stay the same.
After learning why performance optimization is important, let’s look at some popular performance optimization practices for Ruby on Rails.
## Performance Optimization Best Practices for Ruby On Rails
### **1. Optimize server**
Different types of servers are available for other operations, and you should choose the most optimal server configurations for your tasks. If your web application is client-facing and you expect many users to use it continuously, you should select a server with the highest configurations for the best price. You should also check out cloud platforms like AWS, Azure, or Google Cloud for better pricing for optimized servers. This can also save you money while providing significantly better uptime and support.
### **2. Use Load Balancing**
When multiple servers are in your application, yet only a single server receives all incoming traffic and responds to requests, your performance will be better. In such scenarios, you should adopt load balancing to properly utilize all the servers in your application infrastructure.
Depending on your infrastructure and incoming traffic, you can set up load balancing to follow a round-robin pattern, weighted load balancing, or any other pattern. This will help you distribute loads across servers and provide optimal app performance.
### **3. Optimize Ruby Code**
Optimizing your Ruby code will give you the best performance benefits. If you don’t follow clean coding practices, SOLID fundamentals, and other best practices, you won’t be able to develop and deliver highly optimized code, and it will take longer for such code to run. Hence, you should always follow coding best practices and optimize your Ruby code by minimizing loops, avoiding redundant calculations, and simplifying your algorithms.
Once your code is optimized and you have followed the best practices, your app’s performance will significantly boost.
### **4. SQL Indexing**
A primary reason for slow Ruby applications is unindexed databases. When the database does not have an index, it is much slower as it has to work through the entire dataset to fulfill a query. You can improve your app’s performance by creating an SQL index on your database. When making a database index, find the columns accessed frequently and create an index on them to increase the performance significantly.
### **5. Use Libraries and Plugins**
Every language has significant community support, and Ruby is no exception. Its large and active community constantly rolls out newer libraries and plugins for help. When building Ruby on Rails applications, you should focus on using existing libraries and plugins without reinventing the wheel. This will ensure you get the best performance, as various developers use libraries at different scales, and the code is also more optimized.
### **6. Cache Data**
When building enterprise-grade applications, caching becomes an essential feature. Caching the data whenever a request is fulfilled helps decrease the rework for upcoming requests of the same type. This setup increases your app’s performance significantly and returns responses to users at blazing-fast speeds. When building a cache, you should find the frequently accessed items and populate them to avoid frequent cache misses.
### **7. Use Smaller and Compressed Files**
Many times, developers and designers end up using larger files on the Ruby on Rails application, which results in a laggy application that takes a lot of time to load. To tackle this problem and gain performance in your app, you should always use smaller files for images and videos wherever possible.
With smaller files, the pages will load faster, and you will have a better and more optimized application. Also, the creatives being used should be optimized, like disabling animations, which is a crucial approach to [improving Ruby on Rails Test Suite Performance](https://jtway.co/improving-ruby-on-rails-test-suite-performance-by-disabling-animations-2950dca86b45).
### **8. Efficient Query Design**
The execution order of SQL also impacts the performance of your Ruby on Rails application, which is why you should have an efficient query. It would be best to have a well-designed database structure and stronger relationships between tables to create optimized queries for your app.
To significantly boost performance, design queries optimally, utilizing techniques like selective retrieval, efficient joins, eager loading, etc.
### **9. Performance Monitoring**
Monitoring your app’s performance is an essential part of optimizing it. It would be best to use monitoring tools like New Relic and Scout to profile your Ruby on Rails applications and determine their performance in real-time. Performance monitoring also helps you identify bottlenecks in the code so you don’t have to spend time fixing other things and can directly improve the unoptimized code.
### **10. Expand Server RAM**
You may have the best processor and storage for your server, but if the RAM is less, it can quickly become a bottleneck for the application. You can improve your application’s performance by quickly expanding your server’s RAM. When the server has more RAM, its IO decreases as more data can be stored in RAM, boosting the app’s performance and response times.
## Conclusion
Optimizing your Ruby on Rails application’s performance is crucial to its success, and you should not undermine this. If you have an underperforming application, it is time to create a checklist based on the above-discussed ideas and optimize your application for speed.
