Hello and welcome to the 5th post 🧵 of System Design, by @mukeshkuiry ! 

Let's dive into the fascinating world of storage in system design and make this journey more enjoyable with emojis and real-life examples!


### 🔵 Block Storage: Building the Foundation 🧱


Block storage is like the LEGO of data storage! 🧱 Data is split into small blocks, each with a unique ID. These blocks are stored on physical devices, offering lightning-fast access without fixed paths. Think of it as the building blocks for your data center. 💡

For example, in a cloud infrastructure, think of block storage as the individual bricks that make up the virtual server's storage. Each brick (block) can be easily replaced or expanded without disrupting the whole structure.

### 📁 File Storage: Organized and Structured 🗂️


File storage is the neat and organized filing cabinet of data storage. It's perfect for structured data and hierarchy lovers. Data is stored in files, files in folders, and folders in directories. Great for when you need a structured approach. 🗃️

For instance, when managing a website, file storage can be compared to the way web content is organized. HTML files in the `html` folder, images in the `img` folder, and scripts in the `js` folder.

### 📦 Object Storage: Unleash the Power of Flexibility 🚀


Object storage is the superhero of unstructured data! 🦸‍♀️ It's the go-to technique for data archiving, backups, and massive unstructured data sets. You communicate with your data through a RESTful API, offering immense flexibility. Perfect for handling backups, logs, and more. 💪

Consider object storage as the magical backpack for a traveler. You don't need to know the exact location of each item; you just put them in your backpack (object storage) and retrieve them easily when needed.

### 🔄 Redundant Disk Array (RAID): Powering Data Resilience 💽


RAID is the fortress of data storage, ensuring your data's safety and speed. It combines multiple disks to create a robust storage device. Externally, it looks like a single disk, but internally, it's a powerhouse with redundancy and performance. 🏰

In a data center, RAID can be likened to a team of security guards working together to protect valuable assets. If one guard (disk) falters, others step in to maintain security without interruption. 🛡️

The error I encountered when setting up writefreely
Tags: fediverse, go
Published: 2023-11-06 12:33:28

## Purpose of This Article

The setup process for WriteFreely is documented [here](https://writefreely.org/docs/main/developer/setup), but following the steps resulted in an error. This article provides a solution for resolving the error.

## Error Description

When running the `go get` command according to the Quick start guide, the following error occurs:

```
go get -d github.com/writefreely/writefreely/cmd/writefreely

go: go.mod file not found in the current directory or any parent directory. 'go get' is no longer supported outside a module. To build and install a command, use 'go install' with a version, like 'go install example.com/cmd@latest' For more information, see https://golang.org/doc/go-get-install-deprecation or run 'go help get' or 'go help install'.
```

## Cause of the Error

When using a relatively new version of Go, dependency management is performed using Go Modules instead of the `$GOPATH` way. You can choose between `$GOPATH` or Go Modules with the `GO111MODULE` setting. However, the behavior can be quite complex and varies depending on the Go version, as described in the following article:

[https://maelvls.dev/go111module-everywhere/](https://maelvls.dev/go111module-everywhere/)

With newer versions of Go, Go Modules have become mandatory, and `go get` can no longer be used without Go Modules.

## Solution

You can set `GO111MODULE` to `auto` as follows to make it behave like the old `$GOPATH`-based approach:

```
go env -w GO111MODULE=auto
```

After running the above command, you can execute `go get -d github.com/writefreely/writefreely/cmd/writefreely`, and it will download the source code to `$GOPATH/src`. If your `$GOPATH` is not set, you can navigate to `$HOME/go/src/github.com/writefreely/writefreely`.

## Other Notes

* In my environment, `echo $GOPATH`  does not show a value. However,  `go env GOPATH` shows a value. It seems that in recent versions of Go, there is no need to explicitly set `$GOPATH` in files like `.zshrc`.

* When using the `$GOPATH` approach with go get, the source code is downloaded to `$GOPATH/src/`. But when using Go Modules with go get, it is downloaded to `$GOPATH/pkg/mod`.

Wordpress Login with Tailwind CSS
Tags: codepen, wordpress, tailwindcss, webdev
Published: 2023-11-06 12:26:36

A simple screen to replicate the general style of the default WordPress login page. 

The markup is pretty similar to the original login page, this could be improved, but the idea is to show how close of the looking and feel we can get using only Tailwind CSS. 

The only custom CSS done was the Logo image that I couldn't make work using the Tailwind's cdn version. 

Uses the cdn.tailwind.com as the provider of the styles and behavior.

Optimizing Elasticsearch Relevance: A Detailed Guide
Tags: elasticsearch, opensearch
Published: 2023-11-06 11:35:47

How to optimize search results ranking on Elasticsearch and OpenSearch - from the very first steps to the more advanced features it offers.

Elasticsearch (ES) has been dominating the backend of text search apps that are built for heavy usage and top performance. It’s a text-based search engine database that allows you to index, search, and analyze vast volumes of documents within seconds. The near real-time response is achievable by leveraging a unique indexing algorithm that in addition allows distribution across multiple machines and clusters, to support search at scale.

However, performance in terms of query speed and latency is not the only thing you want to have optimized when working with search engine software like Elasticsearch. Retrieving and correctly ranking the relevant documents is a challenge by itself, one that's often viewed as a tradeoff between how fast the results are returned and what’s their relevancy. ES has multiple techniques to improve search relevance ranking, including built in ML features. In this blog post, I’ll demonstrate how you can set up a cluster and apply some methods to control the relevance of the results.

Full text search with Firestore & Meilisearch Deployment to Koyeb
Tags: firebase, mellisearch, backend, javascript
Published: 2023-11-06 11:16:12

In this post we will look into how we can deploy a Melli search instance on their own cloud server as well as deploy it on a [Koyeb](https://www.koyeb.com/) free instance and make a custom search interface to add full text search functionality to our application.

We can deploy Meilisearch to their own cloud provided solution as well as deploy their open source version to our own hosted solution in [AWS](https://www.meilisearch.com/docs/learn/cookbooks/aws), [Digital Ocean](https://www.meilisearch.com/docs/learn/cookbooks/digitalocean), [GCP](https://www.meilisearch.com/docs/learn/cookbooks/gcp), [Koyeb](https://www.meilisearch.com/docs/learn/cookbooks/koyeb) etc.

First in order to create a Meilisearch cloud account go to this link and register.

[https://cloud.meilisearch.com/register](https://cloud.meilisearch.com/register)

They have a minimum pricing of 29 dollars per month, with which you can subscribe to it and immediately gain access to a Meilisearch instance which we can use it in our Backend APIs.

If you feel the cloud version is costly at an initial stage, there is a free open source alternative which you can use it to deploy your instance for free for the initial phase of your application.

I have tried GCP, but it was above 20 dollars per month, so in order to test the features, I went with Koyeb's free instance and eventually upgraded to a paid version as the amount of users increased. 

So head to the below link and create an account.

[https://app.koyeb.com/auth/signup](https://app.koyeb.com/auth/signup)

After that you can create an instance in the region you prefer by providing a master key with which you will access the Meilisearch instance from your backend. The Master key is essentially a API key so keep it secure to access your instance and prevent unauthorised access. Wait for 5-10 minutes and the instance will be deployed.

After you have deployed your instance, you will be provided with a host url, which we will be using the next couple of posts to access the instance and add data points, make search request and apply full text search to the data we have uploaded there.

Below you can see the different deployment options where we can deploy our melli search instance.

Let's look into Meilisearch APIs in the upcoming posts.

You can view the complete code and see how the search interface works in a live demo below.

Published: 2023-11-06 11:06:09

As of my last update in January 2022, the landscape of[ keyword research tools](https://markethio.com/best-keyword-research-tools) was dominated by several powerful options suitable for various needs and preferences.

SEMrush stood out for its comprehensive features, providing not only robust keyword research capabilities but also competitive analysis, site auditing, and backlink data. Its versatility made it a favorite among marketers and SEO professionals.

Ahrefs, another popular choice, offered an extensive database for keyword research, competitive analysis, and backlink insights. It provided a user-friendly interface and a wide array of functionalities for in-depth SEO analysis.

Google Keyword Planner, a free tool, remained a staple for many due to its direct integration with Google's data. It offered insights into search volumes, trends, and keyword suggestions. While primarily designed for Google Ads, it's commonly used for SEO keyword research.

Moz's Keyword Explorer was appreciated for its detailed keyword suggestions and metrics. It provided difficulty scores, SERP analysis, and a prioritization score, aiding users in identifying valuable keywords for their content.

Ubersuggest, developed by Neil Patel, emerged as a user-friendly and cost-effective tool, providing keyword ideas, content suggestions, and backlink data. Its simplicity and accessible layout made it popular among small businesses and solo entrepreneurs.

However, the SEO landscape evolves rapidly. Newer tools may have emerged or existing ones might have significantly improved by 2024. Exploring and researching the latest offerings will be essential to discover the most effective and up-to-date keyword research tools for your specific needs in 2024.

Notação Big-O
Tags: estruturadedados, python
Published: 2023-11-06 10:59:59

A notação **Big-O** é fundamental para a comparação de algoritmos distintos. Seu propósito é determinar a abordagem mais eficiente. Ao enfrentar um mesmo problema, frequentemente nos deparamos com diversas alternativas de solução. O Big-O nos proporciona um insight valioso sobre qual dessas abordagens pode se revelar a mais ágil.

Podemos afirmar sobre a notação Big-O:

- Como comparar dois ou mais algoritmos.
- Comparação objetiva entre algoritmos.
- Considera diferenças entre poder de processamento, sistema operacional, linguagem de programação
- O quanto a "complexidade" do algoritmo aumenta de acordo com as entradas.

**Exemplos**

Vamos supor que precisamos de uma função que some todos os números passados como parâmetros. Teremos duas pessoas desenvolvendo, o que resultará em duas soluções distintas. Nesse cenário, é crucial determinar qual abordagem se mostra mais eficaz.

Exemplo 1:

```
def soma1(n):
    total = 0
    for i in range(n + 1):
        total += i
    return total

time_taken = timeit.timeit(lambda: soma1(10))
print(f"Tempo levado: {time_taken:.6f} segundos")

# Tempo levado: 0.616551 segundos
```

A função **soma1(n)** realiza um loop que itera **n + 1** vezes, onde **n** é o parâmetro passado para a função. Portanto, o número de passos que a função executa é proporcional a **n**.

Dizemos que a função soma1 tem uma complexidade de **O(n)**, onde **n** representa a quantidade de passos e que o tempo de execução da função aumentará conforme o aumento do número de passos.

Exemplo 2:

```
def soma2(n):
    return (n * (n + 1)) / 2

time_taken2 = timeit.timeit(lambda: soma2(10))
print(f"Tempo levado: {time_taken2:.6f} segundos")

Tempo levado: 0.173197 segundos
```

A função **soma2(n)** utiliza uma fórmula matemática conhecida para calcular a soma dos números de 1 a n. (retorna a mesma coisa que a função anterior).

Dizemos que a função **soma2** tem uma complexidade de O(3), onde **3** representa a quantidade de passos(Multiplicação, soma e divisão).

A função soma2 é uma abordagem mais eficiente para o caso, pois já tem uma quantidade definida de passos 'O(3)', afirmando que o quanto a "complexidade" do algoritmo aumenta de acordo com as entradas.

## Conclusão

A notação Big-O é uma ótima abordagem para comparar dois ou mais algoritmos e desenvolver soluções mais rápidas e eficientes.
