Welcome back to the System Design series by @mukeshkuiry ! 🚀

Today, we'll dive into crucial concepts for scalable web applications—DNS and Load Balancers.

## What is DNS? 🌐

**DNS**, or Domain Name System, eliminates the need to remember lengthy IP addresses by mapping domain names to IP addresses. Let's simplify it—imagine you're visiting `www.google.com`. Do you know Google's actual domain address is `172.217.27.174`? Entering this IP address each time you visit Google is challenging. DNS resolves this issue by mapping the IP address with a straightforward domain name; for Google, it's `www.google.com`.

Imagine millions of users accessing Google simultaneously. Due to server limitations, handling this traffic is challenging. Here, DNS Load Balancers come to the rescue. Google deploys multiple servers with different IP addresses, all mapped to the same domain name. The DNS Load Balancer checks server loads in real-time and directs users to the least busy server, optimizing performance.


## What is a Load Balancer? ⚖️

**Load balancing** is pivotal for scaling efforts, ensuring effective scalability with rising traffic while maintaining high availability. Load balancers, acting as reverse proxies, distribute network traffic across multiple servers using various algorithms. This distribution prevents the risk of overwhelming a single machine or a few machines in the cluster with all the traffic.

Load balancing is crucial for avoiding issues. If a server goes down during user request processing, the load balancer automatically redirects future requests to functional servers.

Learn Css Grid Style Layout In 10 Minutes
Tags: css, grid, layout, webdev
Published: 2023-11-24 06:05:45

A grid can be defined as an intersecting set of horizontal lines and vertical lines. [CSS Grid layout](https://www.javatpoint.com/css-grid) divides a page into major regions. It defines the relationship between the parts of a control built from HTML primitives in terms of layer, position, and size. Grid property offers a grid-based layout system having rows and columns. It makes the designing of web pages easy without positioning and floating.

Similar to the table, it enables a user to align the elements into rows and columns. But compare to tables, it is easy to design layout with the **CSS grid**. We can define columns and rows on the grid by using grid-template-rows and grid-template-columns properties.

The CSS grid property is supported in browsers such as Google Chrome, Internet Explorer, Firefox, Safari, and Opera.

[Java]Parallel and concurrent
Published: 2023-11-24 03:58:15

Single-core CPU, thread is serial, there is a component in the operating system called the task scheduler, the CPU time slice (windows minimum of 15 ms) is distributed to different threads. The switching speed of threads is very fast, so it feels that colleagues are actually micro serial, macro parallel.

The practice of threads rotating with the CPU is called concurrent.
(concurrent): The ability to deal with multiple things at the same time
(parallel): The ability to do multiple things at the same time
Angular v17 Hydration Explained! 💻💦
Tags: webdev, angular, javascript, performance
Published: 2023-11-24 03:52:39

Ever wished your Angular app could load faster, ace SEO, and dodge UI glitches? 🚀🪄 That's where Angular Hydration swoops in! Picture it like sending your app for a spa day – all that server-side goodness now chilling on the client's turf, saving you from redoing DOM nodes.

![puppy is doing spa](https://media.giphy.com/media/2hgAt92zs4qbp9Ld4W/giphy.gif)

## What is Hydration?
- Restores server-rendered apps on the client.
- Reusing the DOM, preserving state, and transferring data from the server.

## Why is it Important?
- Boosts Performance: Reusing DOM nodes speeds up loading.
- Enhances Core Web Vitals: Improves FID, LCP, and CLS.
- Improves SEO: Ensures search engines get fully rendered content.
- Prevents UI Issues: Avoids flicker and layout shift.


## Enabling Hydration
- Server-Side Rendering (SSR): Requires an SSR application.
- Use `provideClientHydration`: In the main app component/module.
- Bootstrapping: Include in both client and server providers.

## Constraints
- DOM Structure of server and client must match.
- No Direct DOM Manipulation to keep things smooth.
- Mismatches in DOM structure can cause errors.

## Handling Errors
- Use `ngSkipHydration`: Temporarily bypass issues caused by DOM differences or direct manipulation.
- Skipping Hydration for Components

## Skipping Hydration for Components
- Use `ngSkipHydration` for components incompatible with hydration.
- Useful for components with DOM manipulation issues.

## Considerations
- Internationalization (i18n): No support yet.
- Third-Party Libraries: Some may need `ngSkipHydration` for compatibility.

And there you have it – a quick rundown of the essential facts to consider about Angular Hydration. Have you played around with Hydration yet? 😊

For more details, check out the [Angular Documentation](angular.dev/guide/hydration).
[Java]Process and Thread
Tags: java
Published: 2023-11-24 03:41:25

Process: is used to load instructions, manage memory, and manage IO, process can be seen as an instance of the program (program is static, process is dynamic), when a program is running, it will open a process.
Thread: a process can be divided into one to multiple threads, a thread is the instruction flow, and the instruction flow in a certain order to the CPU for execution.
- In Java, the Thread is the smallest scheduling unit (execution instructions), and the process is the smallest unit of resource allocation (managed resources). In Windows, processes are not active, but only as a container of threads.

- Processes are independent of each other, while threads exist within the process.

- Processes have shared resources, such as memory space etc, for their internal threads.

- Communication between the processes is more complex.

- Process communication for the same computer is called IPC (inter-process communication).
- Process communication between different computers, required through the network, and adherence to common protocols such as HTTP.

- Thread communication is relatively simple because they share memory within processes, and an example is a common variable that multiple threads can access.

- Threads are lighter, and the cost of thread context switching is generally lower than processes.

Angular 17 - Trigger options for @defer block
Tags: angular
Published: 2023-11-24 03:00:00

@defer includes several config options to display errors, placeholder, and loading templates.

Let's focus on the possible triggers for such lazy loading.

⚡idle

This is the default option. Will load the contents of that block once the browser is in an idle state:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jk3b2ughbee3dm1kvxmf.png)

⚡viewport

Triggers the deferred block when its content enters the viewport. For instance, that would be when the user scrolls down, and the block becomes "visible." Note that this option requires a placeholder (used to detect when the element comes into the viewport):

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ndxdq5kzv7y2syh5z62f.png)

Another interesting option is to load the deferred block when another specified element makes it into the viewport using a [template reference variable](https://angular.dev/guide/templates/reference-variables/). That option does not require a placeholder:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0ojb3igy8b4hvrzehbwr.png)

⚡interaction

Waits for the user to [interact with the placeholder](https://angular.dev/guide/defer/?ck_subscriber_id=1979351037&utm_source=convertkit&utm_medium=email&utm_campaign=Angular%2017:%20Trigger%20options%20for%20@defer%20%5BDaily%20Angular%5D%20-%2012230759#on-interaction) to load the deferred block. Even better, this trigger can be combined with another element so you can lazy-load a component on a button click, for instance:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gosolwljog2r3c3nbrqc.png)

⚡hover

Similar to the two previous examples. Waits for the user to hover over the placeholder or a specified element:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jwmkaczvyypeovqvx84h.png)

⚡immediate and timer

[immediate](https://angular.dev/guide/defer?ck_subscriber_id=1979351037&utm_source=convertkit&utm_medium=email&utm_campaign=Angular%2017:%20Trigger%20options%20for%20@defer%20%5BDaily%20Angular%5D%20-%2012230759#on-immediate) triggers the deferred block immediately as soon as Angular has finished rendering. [timer](https://angular.dev/guide/defer?ck_subscriber_id=1979351037&utm_source=convertkit&utm_medium=email&utm_campaign=Angular%2017:%20Trigger%20options%20for%20@defer%20%5BDaily%20Angular%5D%20-%2012230759#on-timer) waits for a specified delay:

TIL: Today I Learned
Tags: ruby, programming, beginners, todayilearned
Published: 2023-11-24 01:09:08

I was (_and arguably still am_) having difficulties grasping certain basic Ruby concepts; especially creating classes and defining methods. I consulted with a TA(John) and he really helped me understand how to define a method. Today I learned that ```def initialize``` allows you to set the initial value for an object.
