SOLID Principles
Tags: beginners, designpatterns
Published: 2024-05-13 05:26:17

**S (Single Responsibility Principle):**
A Class should have only one responsibility. Ex: User class should have functions only related to users.

**O (Open/Closed Principle):**
Open for extension but closed for modification. Means create interface and then extend it to new and old classes but don't change the old class.

**L (Liskov Substitution Principle):**
If class B is a subtype of class A then we should be able to replace the object of A with B without breaking the behaviour. Means subclass should extend the capabilities of parent class not narrow it down (If base class have 3 capabilities/functions then subclass should have at least 3 capabilities/functions).

**I (Interface Segmented Principle):**
Interface should have only necessary functions for subclasses.

**D (Dependency Inversion Principle):**
Class should depend on interfaces rather than concrete classes. Means always create an object of the interface.

*This is a submission for the [Netlify Dynamic Site Challenge](https://dev.to/challenges/netlify): Visual Feast.*


## What I Built
Collagery is a dynamic "collage" / "gallery" builder. Add images to your collagery, specifying the layout and quality of images.

I unfortunately had very limited time for this submission, so I rushed through a lot, but I really wanted to participate. I hope you enjoy playing with it as much as I did building it.

One neat use-case was that you can add the same picture with different quality to get a side-by-side comparison of the images.

## Demo

## Platform Primitives
<!-- Tell us how you leveraged the Netlify Image CDN. -->
This submission uses the Netlify Image CDN to transform and deliver images quickly and efficiently to enhance the user experience. It also takes advantage of a basic caching utilizing the Cache-Control header configured with `public, max-age=604800, must-revalidate`.

The Netlify Image CDN was very easy to get started with and if I had more time I would like to have provided users with more customization of the transforms. The API makes it very easy to use in a dynamic context and would save me a ton of time versus trying to setup my own back-end image transformations and CDN. Cheers to Netlify!

<!-- Don't forget to add a cover image (if you want). -->

## What I Built

A professional profile website for a storyteller, actor, singer, playwright, and director based in Toronto. The site features a CSS-only carousel and a masonary-style gallery showcasing performance images.

## Demo

https://thomas-fournier-astro.netlify.app/

![Masonary-style gallery](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/u4tjw2z3n0fw79jue7fd.png)

## Platform Primitives

Using Astro, I leveraged the Netlify Image CDN to automatically optimize all the images used in the carousel, the gallery, and the lightbox-style popup images. Despite being an image heavy website, it stills scores 100 across the board on the Lighthouse performance audit. The best part was that it required almost no extra effort... all I had to do was add the Netlify adapter to my Astro project. Bam!

## ماهی گلدفیش: دوستانی رنگارنگ در آکواریوم
[
ماهی گلدفیش](https://moorishop.ir/goldfish)، با نام علمی Carassius auratus، یکی از محبوب‌ترین و شناخته‌شده‌ترین ماهی‌های آکواریومی در جهان است. این ماهی زیبا با رنگ‌های متنوع، اندازه‌های مختلف و قیمت مناسب، به انتخابی ایده‌آل برای افراد مبتدی و علاقه‌مندان به دنیای زیر آب تبدیل شده است.


**تاریخچه:**

ماهی گلدفیش ریشه در چین دارد و پرورش آن از دوران سلسله تانگ (618 تا 907 میلادی) آغاز شده است. در ابتدا، این ماهی‌ها به عنوان منبع غذایی پرورش داده می‌شدند، اما به تدریج به دلیل زیبایی و تنوع رنگ‌ها، به عنوان ماهی زینتی مورد توجه قرار گرفتند. در قرن 17، ماهی گلدفیش به اروپا و سایر نقاط جهان راه یافت و از آن زمان تاکنون، به یکی از محبوب‌ترین ماهی‌های آکواریومی تبدیل شده است.

How do SQL interprets nulls?
Tags: webdev, database, sql, backend
Published: 2024-05-13 04:56:20

_Null values in SQL, how are they different from traditional nulls?_

>null, nil, or none is a special value that most programming languages reserve, and it usually means nothing or no value.

Developers usually mistake SQL nulls for having the same meaning, and they end up writing queries that produce unexpected results or a behaviour that is hard to debug.

SQL interprets `null` as `I don’t know` or `unknown` value rather than `nothing` or `no value`.

### What does that mean?
To understand SQL nulls, we first need to know about the three valued logic. Assume that you are a database engine (cool right?), and you're given two black boxes (A) and (B) and asked to compare their content:

- Is black box A the same as black box B? You don't know.
- Okay, is A `greater than` B? You still can't tell!
- How about A `being less than` B? No idea!
- Hmm, maybe A `=` B is doable? Nope.

>And that's exactly how a database engine treats null values; it just doesn't know.

**How do we compare values against null then?** 
It depends, Postgres for example, uses the `is` operator.
So `A is B` will evaluate `true`, and there are other functions that can handle `null` comparisons, like `distinct`.
And that's why you hear people advising against using nulls especially in columns with indexes, because they can affect your index efficiency (more on that on another article).
Next time when you use null, be mindful of this.

Below a picture of the null truth table to make it easier to understand.

Unbelieable Yarn Issue - Solution with node version
Tags: blockchain, yarn, ubuntu, node
Published: 2024-05-13 04:32:45

This time I'm going to talk about an error that looks simple but is very hard to fix with _'yarn install'_ command.

If you work as a software developer working in a NodeJS environment and especially yarn commands, you may encounter this kind of problem frequently.

Then let's see about the issue.


![Error](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7lizn0simvjw1ipk9gz3.png)

When executing the 'yarn install' command in a NodeJS environment, I encountered an error message stating:

> There appears to be trouble with your network connection. Retrying...

After attempting a suggested solution involving a specific flag, the error persisted.

![Error](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ofn4jhoqxa17szurr8ep.png)

Subsequent research led me to suspect a potential issue related to the Node version. Upon downgrading the Node version from 22.0.0 to 18.12.0 and re-running the command, the issue was successfully resolved.

![Solution](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fmweo4xwrvjy0tjlyklt.png)

If anyone else encounters this issue, I recommend trying the solution of downgrading the Node version to 18.12.0. If this solution does not work, or if there are any other challenges, please feel free to reach out for further assistance. Good luck!

Optimizing the Performance of Django SearchVector with GIN Indexing
Tags: django, postgres, performance, coding
Published: 2024-05-13 03:20:55

For a detailed exploration of [Full Text Search using SearchVector](https://dev.to/azayshrestha/a-guide-to-full-text-search-in-django-using-searchvector-p7b).

Django developers mostly use PostgreSQL for its powerful full-text search features. One of the most effective ways to improve the performance of full-text searches in Django is by using GIN (Generalized Inverted Index) indexes. In this blog, we'll explore how GIN indexing can improve the performance of your SearchVector implementation, making your search queries much faster.


**Why Index Your Search Vectors?**
Search vectors are used to implement full-text search in PostgreSQL. They convert text data from one or more fields into a format that can be efficiently queried. However, as your data grows, so does the time it takes to query these vectors. This is where GIN indexes come in. They are designed to handle cases where the items to be indexed are composite values, making them perfect for search vectors that contain tokens generated from text fields.

**Adding a GIN Index to Your Django Model**
The process of adding a GIN index to a SearchVectorField in Django is straightforward yet powerful. Here’s how you can enhance your model's search capabilities:

```
from django.contrib.postgres.search import SearchVectorField
from django.contrib.postgres.indexes import GinIndex
from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField()
    search_vector = SearchVectorField(null=True)

    class Meta:
        indexes = [
            GinIndex(fields=['search_vector'])
        ]
```

```
from django.contrib.postgres.search import SearchVector, SearchQuery
from .models import Product

products = Product.objects.annotate(
    search=SearchVector('name', 'description')
).filter(search=SearchQuery('Cheese'))
```

**Implementing GIN Indexing in an Existing Database**
Once you've implemented the SearchVectorField in your model and created a GIN index on that field, you'll need to populate or update this field to include the actual vector data from your existing records. Here’s how you can do this using Django:

```
from django.contrib.postgres.search import SearchVector
from .models import Product

# Update the search_vector for all products
Product.objects.update(search_vector=SearchVector('name', 'description'))
```

**Benefits of Using GIN Indexes**
With a GIN index applied to your SearchVectorField, you'll notice a significant improvement in query performance, especially as the dataset grows. The index helps PostgreSQL quickly locate entries in the search vector without scanning each entry, which is crucial for efficiency in large databases.
Quality over quanity: What to post on GitHub!
Tags: github, repo, tips, helpful
Published: 2024-05-13 03:20:06

It's not about how many GitHub repositories you have, it's about the code inside them. What they do, what impact your project has, how many people use it. 🧑‍💻

You want to publish almost anything that you are satisficed with and that you think is cool.
You don't want to publish unfinished crappy side-projects, you want to publish projects with potential 💖! Even if it's a work-in-progress you still want to publish it on your GitHub as long as you are *still* working on the project, if not add a `topic` such as "unmaintained" or even archive it! 😵

## But why publish on GitHub?

Well, you can say "I made an app" or "I made a program" or whatever you want but you'll still need proof where if you don't have a GitHub you have no proof.

If you have a GitHub you can have proof or even a license as well as credits to you and your other contributors if you have any.

Not only proving that you made something but also the GitHub *community*, the GitHub community is a truly beautiful thing with open-source contributors around the globe. You can receive feedback, receive bug fixes, or receive code to help out with your project all from open-source contributors on GitHub, who knows maybe you could become an open-source contributor to multiple projects!

## What if I don't use GitHub?

Well, this goes for everything like GitHub! Like Replit, SourceForge, Bitbucket, etc.
Whenever having an account for a platform like GitHub where open-source projects/code is shared, you want to follow the rule of quality over quanity, because it's important.

> An idiot admires complexity
A genius admires simplicity 💖
