A Technical Report on My Observations on https://www.kaggle.com/datasets/kyanyoga/sample-sales-data 


My First Glance Observation of Sample Sales Data
available on Kaggle provides a collection of records related to sales transactions. It consists of a single CSV file containing various attributes that describe each transaction.

File Name: sample-sales-data.csv
Dataset Link: https://www.kaggle.com/datasets/kyanyoga/sample-sales-data

Key Observations:
Data Structure and Dimensions:
The dataset is structured in a tabular format with rows representing individual sales transactions and columns representing attributes of each transaction (e.g., order number, quantity, price, customer details, etc).
Initial inspection suggests there are multiple columns providing different aspects of each transaction.

Attributes and Data Types:
The dataset includes a variety of attributes such as order number, quantity ordered, price each, customer name, address, and sales representative.
Data types likely include numerical (integer, float) for quantitative values (e.g., quantity, price), and categorical (strings) for descriptive attributes (e.g., customer name, sales representative).

Data Quality:
No missing data was immediately apparent noticed upon initial review.
Further investigation into data consistency, validity (e.g., checking for outliers, unusual values), and completeness (e.g., null values) would be necessary to assess overall data quality.



Potential Insights:
Initial analysis could involve exploring sales trends over time (if date information is available), identifying top-selling products or customers, and analyzing sales performance across different regions or sales representatives.
Calculation of aggregate metrics such as total sales revenue, average order value, and customer acquisition rates could provide deeper insights into business performance.

Preprocessing Needs:
Depending on the analysis goals, preprocessing steps might include data cleaning (handling missing values, outliers), feature engineering (creating new variables like total sales amount), and normalization or scaling of numerical data.

In Conclusion:
The "Sample Sales Data" dataset presents a promising opportunity for exploring sales analytics and deriving actionable insights. Initial observations indicate a well-structured dataset suitable for various types of exploratory data analysis and modeling tasks.

A journey of a thousand miles begins with one step they say, I would say my journey into the tech world begins with this post.

I'm a brilliant analytical individual who discovered I have an affinity for numbers and lines of code. I mean I became fascinated with how coding works and while I don't know most functions, I can interpret the basic lines of code and believe me, I do not have any background.

I mean, this post is supposed to be about frontend technologies like HTML, CSS, JAVASCRIPT, JQUERY and the likes but I know so little about them. 
Yes, I have done my research on some of them, especially HTML and CSS and found their uniqueness to be quite confusing. Which is why I need guidance in this newly started journey.
This is where HNG comes in, a free BootCamp where all my worries can be solved. The niche they are going for is ReactJS and this has brought up my learning appetite.
I daresay I do not know anything about it and my research skills have been awakened.

I guess this post is really about getting mentored but if you would like to join me on my journey and watch me grow. You can use any of the links below, it's never too late to start.

I know there will be ups and downs but I'm counting on them, because how then will I grow if I don't face a bit of challenge?
PS: I'm kinda going in for the adrenaline rush also.

Well, this is it for this post.

Git revert commit – Come rimuovere l'ultimo commit fatto
Tags: git, revert, italian
Published: 2024-06-30 12:51:31


Fonte: [Git Revert Commit – How to Undo the Last Commit](https://www.freecodecamp.org/news/git-revert-commit-how-to-undo-the-last-commit/)

Voglio riportare due metodi per poter ripristinare il proprio codice quando per sbaglio del codice errato è stato commitatto o se si ha sbagliato branch di destinazione.

## Il comando `revert`
Il comando `revert`, dopo aver specificato il commit da dover rimuovere,  creerà un altro commit che farà le operazioni opposte alle tue ultime modifiche, ripristinando il codice al suo stato iniziale.
Puoi usarlo in questo modo:
```bash
git revert <commit_SHA_to_revert>
```
Puoi trovare lo SHA del commit che vuoi rimuovere utilizzando `git log`. Il primo commit che verrà visualizzato è l'ultimo commit che è stato creato. Dopo aver individuato il commit, puoi copiare lo SHA e usarlo nel comando indicato precedentemente.  


## Il comando `reset`
Il comando reset è più immediato perchè non c'è bisogno dello SHA del commit per eseguirlo, ma devi prestare molta più attenzione a usarlo, perchè verrà cambiata la history dei commit.
L'operazione fatta dal comando `reset` sposterà il puntamento alla HEAD del branch corrente e scarterà tutto il resto che è stato fatto dopo.
Puoi usarlo in questo modo:
```bash
git reset --soft HEAD~1
```
L'opzione `--soft` significa che non perderai i cambiamenti non aggiunti a un commit che potresti avere.

Se invece vuoi ripristinare l'ultimo commit rimuovendo anche tutte le modifiche non presenti in un commit puoi usare l'opzione `--hard`
```bash
git reset --hard HEAD~1
```  

## Dovresti utilizzare `reset` o `revert`?
Dovresti utilizzare `reset` solo se il commit che devi rimuovere esiste solo localmente e non hai ancora eseguito un `push` per caricare il codice nel repository.
Questo comando cambia la history dei commit e potrebbe sovrascrivere delle modifiche importanti per altri membri del team che stanno lavorando sullo stesso progetto.

Viceversa `revert` crea un nuovo commit che rimuove le modifiche, così se il commit da togliere è già stato caricato nel repository, è meglio utilizzare un revert che non cambia o non rischia di sovrascrivere la history dei commit.
How to Cancel Fetch Requests in JavaScript
Tags: javascript, webdev, beginners, tutorial
Published: 2024-06-30 12:47:49

Ever wanted to **cancel a fetch request in JavaScript?** Discover how the **AbortController **makes it easy to manage and stop async operations. Check out this quick guide to master it in just a few steps!

First, you might wonder when you would need to cancel a fetch request. Here are an examples:

When **filtering a list of elements** in **JavaScript**, the data often comes from an **API**. It’s common to add filtering, pagination, and other features to display the list correctly. However, **JavaScript** does **not guarantee** that fetch requests will be resolved in the **order** they were made.

For instance, if a user applies filters **quickly**, you might make requests A, B, and C in that order. Ideally, you want to display the results of the latest request (C) last. However, due to the fact that the browser and server work **asynchronously**, requests might resolve **out of order**. Request C could be resolved first, followed by A and B, leading to **incorrect data being displayed to the user**.

In such situations, **AbortController **helps by allowing you to **cancel requests A and B**, ensuring only the latest request (C) is active. This way, the user sees the **expected results**.
I’m going to show you **step by step** an example about how to use **AbortController** to handle this kind of situation.

**First**, create an **AbortController instance**. Retrieve the signal from the controller, which will be used to control the fetch request.

![Step 1](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xd77zvsoyjfnbxg3ub23.png)

Then, use the **signal** in the fetch **request options**. Handle the response by logging the data. If an error occurs, check if it's an **AbortError **to know if the request was cancelled using the AbortController. If not, you can handle the error as usual. 


![Step 2](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wkm292dch2vm30xf3bcf.png)


Finally, when you need to **cancel the fetch request**, because for example, a user is selecting a new filter you can use **controller.abort** to cancel the previous request. I’m using a setTimeout in this example for simplicity. 


![Step 3](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zwf2tgo0blkozsqwk7fn.png)


This is the complete code example.
