I run a technical documentation business specializing in writing and editing documentation. I made this series to share my insights and help projects craft impactful documentation.

What's The Criteria?
3- Excellent
2 - OK
1 - Poor

Purposeful: Does the QuickStart explain what problem it's trying to solve? Who is the intended audience?

UX Experience: How seamless is the experience? Must the user create an account to get through the Quickstart? Does the Quickstart elicit a sense of joy and achievement?

Accurate: Are the instructions correct? Are they complete?

## [The Results](https://www.loom.com/share/1bf07e7cec3f47c7b96b1b205232071f?sid=fa8c429b-2836-4e8c-85b5-412dff0a64d7)

Not sure what inspires someone to get up one morning and say, "Yes, I'm going to build another JavaScript framework," but here we are. That being said, I liked Remix's doc's landing page. I was up and running in less than 3 minutes. I think Remix is trying to solve for performance, but I'm not sure. The landing page was full of buzzwords such as "focused on web standards" and "modern web app UX." I wish I could say I care about web standards, but honestly, I want to code up a website in an afternoon and keep it moving. Perhaps I'm not the target audience?

How To Make an Email Link in HTML
Tags: webdev, html, web, tutorial
Published: 2023-11-02 19:48:35

To create an email link in HTML, you can use the `<a>` (anchor) element with the `href` attribute set to the "mailto:" URL scheme followed by the email address. Here's the basic HTML code for creating an email link:

```html
<a href="mailto:youremail@example.com">Send an email</a>
```

Replace "youremail@example.com" with the actual email address you want to link to. You can also add a link text, such as "Send an email," between the opening and closing `<a>` tags. When a user clicks on the link, it will open their default email client with a new email addressed to the specified email.

Here's an example of a complete HTML document with an email link:

```html
<!DOCTYPE html>
<html>
<head>
    <title>Email Link Example</title>
</head>
<body>
    <p>You can <a href="mailto:youremail@example.com">send me an email</a> for any inquiries.</p>
</body>
</html>
```

When someone clicks on the "send me an email" link in their web browser, it will prompt them to open their email client and compose a message to the specified email address.

You can also add additional attributes to the anchor element, such as `subject` and `body`, to pre-fill the subject and body of the email. Here's an example:

```html
<a href="mailto:youremail@example.com?subject=Question%20for%20You&body=I%20have%20a%20question%20for%20you.">Send an email</a>
```

In this example, the subject is set to "Question for You," and the body of the email is pre-filled with "I have a question for you." Make sure to URL-encode the subject and body text to handle special characters properly.


PRO TIP:  Using this method it is possible that a web scraper can scrape your email address from your site and then send spam messages to that email.

Its best to protect your email address behind a captcha.
You can use the free email to link service https://VeilMail.io to protect your email address and prevent email spam.

Should You Learn Vue, React, or Angular?
Tags: webdev, javascript, beginners, programming
Published: 2023-11-02 18:55:17

This question puzzles many beginner front end engineers, but the answer is simpler than you think! In this quick article, we will discuss and give you actionable advice. First, let's start with a quick review of the differences between the three:

## React
Developed by Facebook, React is the least opinionated of the three. It grants the most flexibility and, as a result, the most footguns. Many organizations use it, so jobs are plentiful. It has rich tooling and broad community support due to its overwhelming popularity.

## Angular
Angular is the oldest kid on the block. Coming from Google, it is also the most opinionated of the three. Like React, its tooling is mature and community vast.

## Vue
Vue is the middle road. It is more opinionated than React but less than Angular. It sits somewhere between React and Angular in terms of popularity (at least in my market). Personally, Vue is my favorite, and I write most of my project's front ends in Vue.

## Which One?
The answer is simple: it doesn't matter. The concepts and core UI skills you'll develop overlap. Pick whichever is more prevalent in your local market. A component is the same in all three, as is reactivity, user flow, etc. We should strive to be engineers who can pick up any framework in a week or two. As such, it will behoove you to master fundamental HTML and CSS before moving on to a UI library.

## Takeaway
Pick the one that is most common in your local market. The skills you'll develop will spill over into the other two.

### Retrieval Augmented Chatbot, part 2! LangChain, Hugging Face, Amazon SageMaker, and Amazon OpenSearch Serverless 😀

We start by deploying Mistral 7B, a cutting-edge open-source LLM, onto a SageMaker endpoint. Following this, we work with the Reuters dataset, a Hugging Face dataset comprising 20,000 news articles. We break down these articles into smaller sections and apply bge-small, a compact open-source embedding model, to them. Next, we proceed to index these sections into an Amazon OpenSearch Serverless vector index, which we then query through LangChain. Additionally, aside from the RAG demonstration, we delve into some vital yet often overlooked steps related to authentication and security for OpenSearch Serverless.

Adding dark mode button
Published: 2023-11-02 02:18:40

Hello Everyone,
In this project i have worked to add dark mode button which help user to toggle between two shades and help to make more user friendly.
 I integrated a user-friendly toggle button that allows users to switch between **light and dark modes** with ease. The addition of dark mode not only provides a visually appealing alternative but also contributes to reduced eye strain during nighttime browsing. It was a rewarding experience to work on this feature, ensuring that our web application caters to a wide range of user preferences and creates a more immersive and comfortable environment for our audience.

The key features of adding a dark mode button to a web application include:

- User-Friendly Toggle Button: A prominent and intuitive button or switch that allows users to easily toggle between light and dark mode.
- Improved Readability: Dark mode typically features light text on a dark background, enhancing readability, especially in low-light environments.
- Customizable: Some implementations allow users to customize the dark mode, such as adjusting contrast or selecting different dark color themes.
- Saves Battery (for Mobile Devices): On mobile devices with OLED or AMOLED screens, dark mode can save battery life because individual pixels are turned off in dark areas of the screen.

I was reading "How Query Engines Work" by Andy Grove and it was a fascinating deep dive into the internals of query engines. Here are my main takeaways:

- SQL remains a popular interface for interacting with query engines and databases, facilitating efficient data retrieval.

- SQL queries are translated into logical and physical plans, which are then optimized by the query engine's optimizer before execution.

- Optimization rules like Projection Push-Down and Predicate Push-Down play a crucial role in enhancing performance.

- To gain insights into query performance examine the query plan (In Postgres, you can use the command EXPLAIN SELECT * FROM mytable).

- The optimized query plan is executed by the query engine's executor against the specified data source, resulting in the retrieval of the desired data.

- Transaction Processing Council (TPC) Benchmarks are standardized tests used to evaluate the performance of database systems.

- Datafusion: A fast and extensible query engine utilized in Apache Arrow, which is currently being used internally by InfluxDB.

* The most interesting thing mentioned is Apache Flight Protocol built on top of gRPC, facilitates the seamless streaming of Arrow data over the network.

The Complete Guide to Time Series Models
Tags: datascience, dseafrica, timeseriesmodel, completeguide
Published: 2023-11-02 18:13:01

**Introduction**
Time series analysis is a statistical technique which is used for analyzing and predicting the data that evolves over time.it has applications in different fields like economic, finance, forecasting. time series models are mathematical models which capture the patterns and relationships within the time-independent data. In this article we provide a complete guide for understanding and implementing time series models.
**What is time series?**
Time series is a set of points which are collected at regular intervals over time. we can represent them as a set of observant shown over the time. time series data often shows trends, seasonality, and other patterns that can be analyzed and utilized for forecasting future values. The main goal in using a time series is to predict future values. The first step in time series is to draw a graph of the data. with drawing a graph, we can identify general information, including an upward or downward trend, the presence of a seasonal pattern, a periodic trend, and the presence of outliers in the data. After plotting the data, the data must be stationary in order to have a proper prediction. Data can be made static by using differentiation or decomposition into its constituent components. After stabilizing the data, the order of the moving average and the order of autoregression of the model can be identified using the graph. It is necessary to examine the obtained parameters for significance using T-test. If it is significant and there is no dependence in the remainder, a suitable prediction can be made with the help of past data, also the predicted values can be evaluated using the absolute average percentage of error.
**The component of time series models**
Time series models are consist of 3 part:
•	Trends: long term pattern or movement in data.
•	Seasonality: predictable or repetitive patterns that happen in a specific time period.
•	Residuals: The random fluctuations or noise in the data that we cannot explain them by the trend or seasonality.
**Different kinds of time series models**
•	Autoregressive Integrated Moving Average (ARIMA)
•	Exponential Smoothing (ES)
•	Seasonal Autoregressive Integrated Moving Average (SARIMA)
•	Vector Autoregression (VAR)
**Analyzing and choosing model**
For choosing the best time series model for a specific dataset, we can use different evaluating techniques. These include analyzing residual plots, calculating evaluation metrics like mean squared error (MSE) or Akaike Information Criterion (AIC), and performing cross-validation.
**Model Training and Forecasting**
When we choosed the appropriate time series model we have to train the model with historical data. This happens with estimating the model parameters based on the data. we can use the model to predict future values by extrapolating the patterns captured in the training phase.
Create Your Project’s GitHub Readme With 4 Simple Questions
Tags: github, opensource
Published: 2023-11-02 17:51:03

**Writing a readme on GitHub is no rocket science. You're probably after the two most important steps in reverse order of difficulty: creating the project, and naming it. Here's how you can create an awesome readme to your project.**

---

When I studied journalism almost a decade ago, I was taught to answer these 4 questions (+2 optionally) when writing an article:

- **What?**
- **Who?**
- **When?**
- **Where?**

Writing an awesome GitHub readme is no different to this. When someone finds out about your project, and wants to find out if it'll be helpful for them, you can help them by answering these questions.

## What?

This is pretty simple. Just state what your project is about. The easiest formula to follow here is to put it in a simple sentence what your project does.

**Pro tip:** Include a demo video or some sort of visualization. Words can describe what your project does, a video or a gif can present it for instant understanding.

## Who?

The second most important question you have to settle is who the project is for. It's important to signal any dependencies or technical constraints right from the get go. It can be any language or OS specific constraint, but you have to be upfront about it, so the user doesn't waste time on researching something they simply can't use to solve a problem.

## When?

A well written use case describes a situation when a user can benefit from your project. You clearly understand the problem the project solves, so you can just simply write down a scenario when you were frustrated and your solution would've been useful.

**Pro tip:** Sometimes your users find new use cases, so feel free to add new items to this part on the fly when you find out about it. You never know how commonly the use cases your users figure out emerge in real life.

## Where?

This is pretty simple: include where your users can get started. This might be an npm or a docker command, or a link to somewhere. In case a user needs to do some type of configuration, it's good to have some form of description about the necessary steps to spark up your project.

### Here's an Example

Check out [dyrector.io's readme](https://github.com/dyrector-io/dyrectorio#readme) and see how we did with this formula.

We wanted a readme that describes how the project is useful by answering the questions:

- What? ✅
- Who? ✅
- When? ✅
- Where? ✅

And additionally, we added one of the two optional ones (**how** & **why**), as well:

- **How?** Described how the solution works by describing dyrector.io's stack and including a diagram.

## Give us a ⭐ on GitHub

Did you like this blog post? Well, I have no platform where you can support me, but...

Can you take a second and star dyrector.io's repository on GitHub at the link below?

What is Horizontal and vertical scaling?
Tags: webdev, programming, systemdesign, beginners
Published: 2023-11-02 17:34:09

**Hello 👋 & welcome** to the 2nd post 🧵 of System Design by @mukeshkuiry

Let's chat about a key system design concept! We're diving into "**Horizontal and Vertical Scaling.**" 📊📈🖥️


In simple terms, scalability 🗄️ refers to the ability of an application to handle the increased 📈 traffic load without sacrificing latency.

The server should be powerful 💪 enough to handle the increased workload.

There are mainly two ways to scale things up.


## Horizontal scaling


Horizontal scaling, often known as "**scaling out**," is the process of increasing the number of nodes and machines 🖥️ in the resource pool.

In simple terms, Imagine you have a bakery 🍰 and need more customers. Instead of making a bigger oven, you add more ovens to keep up with demand. This is like horizontal scaling!

Horizontal scaling allows for easier scaling through hardware additions, providing enhanced flexibility, 📈 minimizing downtime, and offering redundancy. 🔄🛡️

While the initial setup cost is higher 💹  and it's harder to maintain.


## Vertical scaling


Vertical scaling, also known as "**scaling up**," is the process of increasing the existing system, such as CPU or RAM 💽, to meet the rising demand.

Now, picture you have a computer 💻, and it's getting slow because you're running many applications. To make it faster, you upgrade its CPU and RAM. This is vertical scaling!

Vertical scaling offers low 🔻 cost scaling, less complexity, and easier to maintain.

While it possesses more downtime 📉 possibilities, less flexible, and there is also a single point of failure ❌ .

## Which one to choose?

Choosing the right scaling method depends on various factors:

• **Performance** 🚀: When dealing with computationally intensive tasks, vertical scaling is your go-to choice.

• **Cost** 💰: If you're on a tight budget, vertical scaling is the economical option, as horizontal scaling tends to be pricier.

• **Future-proofing** 🌟: To boost your business performance and prepare for future growth, horizontal scaling is the way to go.

• **Flexibility** 🧩: If expanding your codebase seems complicated, horizontal scaling offers greater flexibility.

• **Topographic distribution** 🗺️: For a nationwide user base, horizontal scaling is the way to go. But if your users are concentrated in a single city, vertical scaling may be the better fit.
