API integration in RUST
Tags: rust, programming, developer, api
Published: 2024-06-01 09:10:54


### Setting Up a Basic API in Rust

#### Prerequisites
To follow along, ensure you have Rust and Cargo installed. You can install them using the official [Rustup](https://rustup.rs/) installer.

#### Creating a New Rust Project
Start by creating a new Rust project:

```sh
cargo new rust_api
cd rust_api
```

#### Adding Dependencies
Add dependencies for an HTTP server. For this example, we'll use Actix Web:

```toml
# In Cargo.toml
[dependencies]
actix-web = "4.0"
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
```

#### Writing the API Code
Create a simple API endpoint that responds with a JSON object. Edit the `src/main.rs` file:

```rust
use actix_web::{web, App, HttpResponse, HttpServer, Responder};
use serde::Serialize;

#[derive(Serialize)]
struct MyResponse {
    message: String,
}

async fn greet() -> impl Responder {
    let response = MyResponse {
        message: String::from("Hello, Ali!"),
    };
    HttpResponse::Ok().json(response)
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new()
            .route("/greet", web::get().to(greet))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}
```

#### Running the API
Run the API server with:

```sh
cargo run
```

Visit `http://127.0.0.1:8080/greet` in your browser or use `curl` to see the JSON response:

```sh
curl http://127.0.0.1:8080/greet
```

### Best Practices for Rust API Integration

#### Error Handling
Use Rust’s powerful error handling mechanisms to ensure your API can gracefully handle and respond to errors. Libraries like `anyhow` and `thiserror` can simplify error management.

#### Logging
Implement logging to track API activity and debug issues. The `log` and `env_logger` crates provide flexible logging options.

#### Serialization and Deserialization
Utilize `serde` for efficient JSON serialization and deserialization. Ensure your data models derive the necessary traits for seamless JSON handling.

#### Testing
Write comprehensive tests for your API endpoints using Rust’s built-in test framework. Actix Web’s test module allows for easy testing of HTTP requests and responses.

#### Security
Implement security best practices such as input validation, authentication, and authorization. Libraries like `jsonwebtoken` can help with JWT-based authentication.

#### Documentation
Document your API using tools like `Swagger` or `OpenAPI`. This not only helps other developers understand how to use your API but also aids in maintaining it.

Tags: aws, devops, learning, beginners
Published: 2024-06-01 09:41:21

In the dynamic world of cloud computing, staying ahead of the curve is crucial. As I delve deeper into AWS, I've discovered a transformative feature that significantly enhances how we manage our infrastructure: _AWS Auto Scaling_.

## What is AWS Auto Scaling?

AWS Auto Scaling is a powerful service that allows you to automatically adjust your application's capacity to maintain steady, predictable performance at the lowest possible cost. It provides a hands-off approach to scaling your instances, eliminating the need for manual intervention and constant monitoring.

## Key Capabilities of AWS Auto Scaling

**Automatic Scaling**

AWS Auto Scaling automatically adjusts the number of EC2 instances in response to changes in demand. Whether you're experiencing a sudden spike in traffic or a lull, Auto Scaling ensures your application always has the right amount of resources.

**Dynamic Scaling Policies**

With AWS, you can define dynamic scaling policies based on various metrics like CPU utilization, memory usage, or custom CloudWatch metrics. These policies allow your application to respond to real-time changes efficiently, scaling up during peak times and scaling down during off-peak periods.

**Scheduled Scaling**

For predictable traffic patterns, AWS allows you to schedule scaling actions. This means you can pre-define scaling activities to align with anticipated load changes, ensuring optimal performance without the need for manual adjustments.

**Predictive Scaling**

AWS Auto Scaling uses machine learning to predict future traffic patterns and proactively adjust your resources. This cutting-edge feature minimizes response times and maximizes cost efficiency by forecasting demand and preparing your infrastructure accordingly.

**Integrated Monitoring and Alarms**

AWS integrates with CloudWatch to provide comprehensive monitoring and alerting capabilities. You can set up alarms to notify you of any unusual activity, ensuring you're always in control and informed about your application's performance.

## Why AWS Auto Scaling is a Game-Changer
- Cost Efficiency: By scaling down during low demand periods, you save on unnecessary infrastructure costs.
- Enhanced Performance: Automatic scaling ensures your application remains responsive and performant, even under varying loads.
- Reduced Operational Overhead: Eliminates the need for constant manual adjustments, freeing up your team to focus on more strategic tasks.
- Scalability: Easily handle traffic spikes and growth without any manual intervention, providing a seamless experience for your users.

## Real-World Impact

Imagine running an e-commerce site that experiences a surge in traffic during holiday sales. With AWS Auto Scaling, your infrastructure can automatically scale to handle the increased load, ensuring a smooth shopping experience for your customers. Post-sale, it scales down to save costs, maintaining efficiency.

Q- What is manual testing? What are the benefits and drawbacks?

A- Manual testing is a type of testing where all the functionalities of the software are tested manually by testers based on customer requirement. It is to check whether all the functionalities are behaving/working as expected in order to deliver a quality and bug free product to the customers/clients.

: Benefits of manual testing

Human intelligence is used to identify bugs in manual testing.
programing knowledge is not required.
more useful to find potential defects with the help of human observation.
Useful for testing graphical user interface.
: Drawbacks of manual testing

It is Time consuming.
It requires more man power compared to automation.
Handling large amount of data is impractical in manual testing.
performance testing is impractical in manual
TASK 3

Q-Difference between functional testing and non functional testing

A-Functional testing is a type of software testing where each functions and features of the software are tested to know whether the functionalities are workings as expected or not.
example: new modules have been added to the present build, need to perform regression testing in order to check whether other aspects of the build has been affected by this module or not.

Non functional testing is a type of testing where the non functional aspects of the software are tested such as load, performance, speed, usability etc.
example: thousands of people trying to login at the same time, in order to test this load testing can be performed.

Types of functional testing are unit testing, integration testing, system testing, smoke testing, regression testing, etc.

Types of non functional testing are performance testing, load testing, stress testing, security testing, etc.

Functional testing is done based on customer requirements and non functional is focused on customer expectations. Functional testing can be done manually where as it is difficult to do non functional testing without the help of tools.

Both functional and non functional are equally important in order to deliver a finished and quality product to the clients/customers/end users.

Q: What is software testing?, What to we need to know about software testing?, What is the relevance of software testing?

A: Software testing is nothing but to test a particular software to make sure that the software is bug free/defect free in order to deliver a quality product to the customer/end users according to their requirements.

Software testing is a very important phase for any given software in to deliver a quality product to the end users.

The software testing is part of SDLC(software development life cycle) and this consists of 6 stage and they are

requirement analysis
designing
development
testing
deployment
maintenance
Without testing a particular software it cannot be launched or deployed to the end users. It is very important to test the software to prevent bugs and to improve performance of the software.

Software testing helps in identifying defects and issues in the development process so that they are fixed before deployment or prior to launch. This process helps to ensure that only quality products are distributed to the customers which results to customer satisfaction and trust.
Lively Search Input with Animated Border Progress
Tags: css, webdev
Published: 2024-06-01 08:52:03

Ever stared at a blank search bar, willing it to return results faster?  We've all been there. I've decided to explore a unique search input design that adds a touch of interactivity and user feedback to the search process in my graph database administration tool.

### The Power of Visual Feedback

A static search bar provides little indication of progress. My design incorporates a dynamic border that animates while the search is ongoing.  This visual cue informs the user that the system is actively processing their request, reducing the perception of wait time and improving the overall user experience.

### Behind the Scenes

This animation is achieved using CSS preprocessor code, specifically Sass. The `clippath` is used to define the animation, creating a clipping effect that progresses around the border of the search input.

```sass
@keyframes clippath
  0%, 100%
    clip-path: inset(0 0 95% 0)
  15%
    clip-path: inset(0 95% 0 0)
  50%
    clip-path: inset(95% 0 0 0)
  65%
    clip-path: inset(0 0 0 95%)

.border-progress
  &::after
    content: ""
    position: absolute
    top: 0
    left: 0
    right: 0
    bottom: 0
    border: 2px solid var(--bulma-link)
    transition: all .5s
    animation: clippath 3s infinite linear
    border-radius: var(--bulma-input-radius)
```

_Solution is implemented in project using Bulma css framework_

Over the weekend I found myself coding a JS game for my kids. The game is very straightforward a word scrambler for kids at the ages of 6-9.
After finishing the first version, I sent the game to some colleagues to get feedback, and here are the things I learned:
- plan the game before you start coding. Try to imagine the game flow, write the scenes on paper, and try to understand the game as it is.
- Big control: while coding, always test your code, and see if things are working as expected.
- get your kid's opinion, about everything, colors, text, words, settings.
- feedback is important, while they are playing the game, kids, especially young ones, must have some kind of feedback, preferably visual.
- hints and help: following the previous point, they sometimes need help. Adding some kind of help/clue after 2-3 failures is a must, otherwise, they will feel frustrated.

Survey: Supply chain risk’s impact on corporate financial performance
Published: 2024-06-01 07:48:25

## 選定理由

引用論文が非常に多く、よく研究されている印象。また過去に例のないアプローチをしており、チャレンジングである。

Paper: https://e-tarjome.com/storage/btn_uploaded/2022-05-11/1652243425_12411-English.pdf
Code: N/A

## 概要

【社会課題】
SCリスクが企業の財務業績にどのように影響を与えるかについて十分な検証がなされておらず活用されていない。

【技術課題】
SCリスクと企業の財務業績の間の定量的な因果関係は未解明である。サプライチェーン管理の分野では過去にほとんど研究されていない。

【検証内容（提案）】
アンケート調査と財務諸表データを使用して、限界財務業績（MFP）の観点からSCリスクが企業の財務業績にどのように影響するかを分析した。20業種にわたる106の台湾上場企業を対象に、構造方程式モデリングを用いて仮説を検証。

【検証結果（効果）】
業界固有のリスク、組織リスク、内部業務プロセスリスク、および需要リスクの重要性に関する結果は、先行研究と一致。需要リスクが−0.20のMFPを持ち、リスク変数の中で最も高い負の影響を持っていた。また、業界固有のリスクが−0.16のMFPを持ち、直接的な財務業績への影響はないにもかかわらず、二番目に高い負の影響を持つことがわかった。

## 検証内容

### 研究仮説

先行研究に基づき、サプライチェーンリスク（SCR）が企業の財務パフォーマンスに与える影響を定量的に評価する以下の因果モデルを仮定した。

*  H1a: 業界特有リスクは供給リスクに正の影響：業界特有の不確実性が供給リスクを増加させる[Chopra&Sodhi 2004]
*  H1b: 業界特有リスクは需要リスクに正の影響：製品市場の変動性や技術革新が需要リスクを高める[Lee, Padmanabhan & Whang 1997]
*  H2a: 組織リスクは供給リスクに正の影響：内部の管理不備や労働力の不安定性が供給リスクに影響する[Kleindorfer & Saad 2005]
*  H2b: 組織リスクは需要リスクに正の影響：組織内部の不安定性や競争が需要リスクにも影響を与える[Christopher & Peck 2004]
*  H3a: 内部ビジネスプロセスリスクは供給リスクに正の影響：生産サイクルの遅延や品質管理の問題が供給リスクを増加させる[Tang 2006]
*  H3b: 内部ビジネスプロセスリスクは需要リスクに正の影響：内部プロセスの改善遅延が需要リスクを高める[Flynn et al. 2010]
*  H4: 供給リスクは企業の財務パフォーマンスに負の影響：供給チェーンの途絶や品質問題が企業の財務パフォーマンスに直接的な影響を与える[Hendricks & Singhal 2005]
*  H5: 需要リスクは企業の財務パフォーマンスに負の影響：需要の変動が企業の財務パフォーマンスに大きな影響を与える[Stevenson & Spring 2007]

これは以下の図１のような因果モデルとなる。

![fig1](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sg9ojlp6lrryo60iv9e7.png)

### データと分析方法

データは主にアンケート調査と財務報告書から取得した。アンケートはサプライチェーン管理に関する知識を持つ経営者に送付され、150社に配布して123社から回答を得、そのうち106社のデータを使用した。財務データは各企業の公開財務報告書から収集し、前年度のデータを分析した。測定項目には業界特有のリスク、組織リスク、内部ビジネスプロセスリスク、供給リスク、需要リスク、および利益率（CFP1:PM）、総資産利益率（CFP2:ROA）、株主資本利益率（CFP3:ROE）が含まれる。データ分析には因子分析と構造方程式モデリング（SEM）を用いて、仮説の検証とリスク要因が財務パフォーマンスに与える影響を定量的に評価した。

## 検証結果

![fig2](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4kv72mi7dnps5i917kxy.png)

需要リスク: 企業の財務パフォーマンスに最も大きな負の影響を与える（MFP＝−0.20）。これは需要の変動や予測困難性が直接的に売上や利益に影響するため。
業界特有のリスク: 間接的に財務パフォーマンスに影響を与える（MFP＝−0.16）。業界特有の不確実性が供給リスクや需要リスクを増加させる。
供給リスク: 財務パフォーマンスに直接的な影響は見られなかった。企業が供給リスクを効果的に管理できている可能性がある。
組織リスク: 供給リスクに影響を与えるが、需要リスクには影響しない。これは、企業が内部管理を強化しているためと考えられる。

予想外の結果に関する考察
供給リスクと財務パフォーマンス: 供給リスクが財務パフォーマンスに影響を与えないことは、企業がサプライヤーとの関係を適切に管理している可能性を示唆。
組織リスクと需要リスク: 組織リスクが需要リスクに影響を与えない理由として、台湾の企業が顧客との関係をうまく管理していることが挙げられる。

Use git pull --rebase origin develop when you pull latest develop branch
Tags: git, github
Published: 2024-06-01 07:34:40

`git pull --rebase origin develop`

What a useful command!
When you join develop team, you　always use git.
But...
When you complete code and push it to remote repository, you look conflict message, so it slightly sad.

Then Whenever you use `git pull --rebase origin develop`.

### Condition
Development team must follow `Git-Flow`.
It's branch strategy.

```
main branch
develop branch
feature branch
```

### When use it
First you create new feature branch.
Second you're coding.
Third you enter `git pull --rebase origin develop`, after Lunch.
So develop branch may have been updated.

It's also good when coding is done, you enter it.

If there is nothing else,

```
Successfully rebased and updated xxxx
```
OK, No Conflict.
Let's push it.

But you catch conflict message, you fix code.

You enter blow command after you fix it.
```
git add fixed file
```

You enter blow command.

```
git status
```
If it's no conflict,

```
nothing to commit, working tree clean
```

Ok, next you enter blow command, so you finish rebase.

```
git rebase --continue
```

If It's no problem,

```
Successfully rebased and updated xxxxxx
```

How about it?
It's easy way.
But you carefully research `rebase` and `pull`, so you use command.

Have a good engineer life.
