NestJS Kafka Consumer Retry
Tags: kafka, nestjs, retry
Published: 2023-12-05 09:32:19

Hello,

I am trying to understand the consumer retry behaviour with NestJS, which uses KafkaJS under the hood.  If a consumed message is retried, does it use [KafkaJS retry behaviour](https://kafka.js.org/docs/retry-detailed)?

If the retry exceeds the configured consumer sessionTimeout, is the consumer removed from the consumer group, a consumer group rebalance triggered, and the message redelivered?  (Resulting in potential duplicate message processing).

Or is the message retried from the topic each time, potentially resulting in a poison pill (being redelivered forever and blocking the topic) if it fails for the same reason each time?

Thanks,
Rob.
Wakatime and Jest
Published: 2023-12-05 09:26:49

I forgot to install two tools for testing and monitoring my time during development. Time flies when we're engaged in something interesting, but now I can track better where I spend my time. [Wakatime](https://wakatime.com/). 

As you can see, I'm a super senior who codes for only 1 minute per week.
![joke](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vl4id2tolkll5nzxigv3.png) 

For testing, I'm going to use Jest because it's easy to use, and all the tests that I'll automate are unit tests. I expect to create at least one unit test for each component, but I'm still considering.
An alternative for Render?
Tags: hosting, webdev, github
Published: 2023-12-05 09:17:32

I have been using [Render](https://render.com/) for hosting my side projects. It's flawless, easy to connect GitHub projects and deploy with just a click.

I switched to render because I was fed up with the hard and weird deployment process of Heroku. Render has some amazing features and easy to use.

But recently, I faced this problem of services getting suspended if they are in free tier. Somehow, it's hard to afford some side projects in a paid plan. I share my side projects with my friends and they say it's not loading. I ask them to wait for couple of minutes and they usually stop trying after some time.

Currently, I am searching for a better alternative which provide full time serving of the web app we deploy. I really liked the workflow of [Render](https://render.com/) and hope to find something similar.

Understand web Accessibility: what's an accessibility overlay? (part 4)
Tags: a11y, webdev, learning, html
Published: 2023-12-05 08:43:33

## What's an overlay for web accessibility?

Automated solutions that claim to both detect web accessibility issues and fix them in compliance with the WCAG. Implemented via JavaScript code snippet or on behalf of the host site and work to adress a11y issues using heuristic engines that 'fix' issues directly on the website interface.
Most are displayed as a toolbar or widget a11y options that allow users to adjust the experience. These vendors promise to provide one-click compliance with a11y overlay tools.

## My vision in a nutshell
I don't recommend using permanent overlay plugins. 
We view these kinds of products as actively harmfull, and a step backwards for digital accessibility efforts.
Also, Over **250 lawsuits** in the USA were filed in 2020 against companies using widgets or overlays as an accessibility solution for their websites.
上流、中流、下流：ITプロセスシステムの違いを理解する
Tags: 上流, 中流, 下流
Published: 2023-12-05 08:25:45



ITのダイナミックな世界では、プロセスがプロジェクトとシステム開発の重要な要素となります。エネルギーや製造業界の用語を借りた「上流」、「中流」、「下流」という概念がITの領域にも導入されました。この記事では、上流、中流、下流のITプロセスの違いとその情報技術領域での重要性を探求し、掘り下げていきます。

## 1. 上流のITプロセス
上流のITプロセスは、どんなプロジェクトでもその原点です。ここでプロジェクト全体の基盤が築かれます。上流のITプロセスの主要な側面を見てみましょう:
プロジェクトの開始: 上流のフェーズはプロジェクトの出発点です。アイデアが生まれ、初期の計画が始まります。この段階ではステークホルダーがプロジェクトの目標、スコープ、要件を定義します。プロジェクトの方向性を正しく設定する時です。

- 要件の収集: 上流のプロセスの最も重要な側面の一つが要件の収集です。この段階では詳細な要件が収集され、文書化され、洗練されます。効果的な要件収集は、プロジェクトの目標を全てのステークホルダーが明確に共有し、理解するために不可欠です。
- リスク評価:
 上流のフェーズで潜在的なリスクと不確実性を特定することは非常に重要です。この段階で効果的なリスク評価を行うことで、リスク軽減戦略が開発され、ステークホルダーと共有されるため、意思決定者の明確な方針を示すことができます。

## 2. 中流のITプロセス:
中流のITプロセスはプロジェクトの中間地点を占めます。ここではデータの輸送、保管、処理に関連するタスクが行われます。中流のITプロセスの主要な側面を探ってみましょう:

- データ処理: 中流のステージはしばしばデータ処理活動の中心です。プロジェクトの性質に応じて、データの変換、分析、その他のデータに関連するタスクが含まれることがあります。
- データの保管と管理: データ駆動のITプロジェクトにとって効率的なデータの保管と管理が不可欠です。これにはデータベースの設定、データウェアハウスの構築、データガバナンスポリシーの確立が含まれます。データのセキュリティとアクセス性を確保することが求められます。
データの統合: 中流のプロセスでは、さまざまなソースからのデータの統合が頻繁に行われ、データの一貫性とアクセシビリティを確保します。

## 3. 下流のITプロセス:
下流のITプロセスはプロジェクトの最終段階を表します。ここで最終製品またはシステムが準備され、パッケージ化され、最終ユーザーや消費者に配布されます。下流のITプロセスの主要な側面を以下で紹介します:
ソフトウェアの開発とテスト: ソフトウェアプロジェクトの文脈では、下流プロセスにはコーディング、テスト、品質保証活動が含まれます。これがデジタル製品が最終形を取る場所です。

- 展開と配布: これはソフトウェアまたはシステムを最終ユーザーに展開する段階です。展開戦略の定義、配布チャネルの確立、ユーザートレーニングなどが含まれます。
- 顧客サポートとメンテナンス: 実装後、顧客サポートの提供、保証の処理、システムの定
期的なメンテナンスが下流のITプロセスの重要な側面です。ユーザーエクスペリエンスを確保するために必要です。

## 4. 結論
上流、中流、下流のITプロセスの違いを認識することは、効果的なプロジェクト管理とシステム開発に不可欠です。それぞれのフェーズには独自の要件、課題、目標があります。これらのフェーズ間での明確な遷移はプロジェクトの成功にとって重要です。これらの違いを理解し、認識することにより、ITプロフェッショナルはステークホルダーの期待に合致し、ビジネスの全体的な目標を達成するプロジェクトをより良く計画し、実行し、提供できます。これらの違いは、複雑なITプロジェクトの複雑な景色を航海するための貴重な指針となります。[マイクロサービスにおける上流・下流とは?APIのテストに関する課題?] に関するこの記事は、上流、中流、下流の区別についてより一般的な概要を理解するのに役立ちます。

Isolation Levels - part VI: Snapshot Isolation
Tags: sql, database
Published: 2023-12-05 08:12:00

In databases that use multi-version concurrency control (MVCC), the **Snapshot Isolation (SI)** technique is used as the basis for read-only and serializable isolation levels. SI helps prevent most anomalies and phantom reads, but it does not protect against write skew. In order to handle write skew, the Serializable isolation level requires additional conflict detection. SI aligns with the SQL-92 specification for **Repeatable Read** isolation level and offers additional protection against phantom reads.

**Write skew** happens when two transactions read certain rows, make decisions based on the results, and then write to rows that affect the original read results. If the writes of these transactions don't conflict with each other, meaning they don't write to the same row, they won't block each other. However, because one write changes the state that was initially read, it makes the decision of the other transaction incorrect. 

To illustrate this, consider a scenario where two human resources managers are instructed to award a bonus to a random employee for each team where no bonuses have been given yet. If both managers query the system at the same time, they may award the bonus to different employees from the same team. Two bonuses have been granted to the same team when both transactions are committed. While such cases are rare in practice, they can be avoided by writing some information to a common record so that the two transactions cannot overlap.

Snapshot Isolation in MVCC databases corresponds to the Repeatable Read isolation level but also safeguards against another anomaly not mandated by this level, according to the SQL specification: phantom reads. It is worth noting that **Oracle** highest isolation level is Snapshot Isolation, even if set with SERIALIZABLE, due to their interpretation of SQL92 definitions when implementing non-blocking reads with MVCC. To achieve a true ANSI SQL Serializable isolation level, more locking was required with a [serializable=true](https://docs.oracle.com/cd/B10500_01/appdev.920/a96590/adg08sql.htm#14762) non-default parameter. However, this approach is now deprecated as you can explicitly LOCK TABLE if needed.

Here are the characteristics of the Snapshot Isolation isolation level in **YugabyteDB**, which you get by setting Repeatable Read isolation level (also with Read Committed when `--yb_enable_read_committed_isolation=false`)

- **Read time**: the start of the transaction
- **Possible anomalies**: write skew
- **Performance**: no overhead, uses MVCC
- **Development constraint**: the application must catch serializable errors and implement a retry logic. Write skew situations must be managed by the application with implicit locking or having the transaction logic in a single SQL statement.
Building facade advertising

Published: 2023-12-05 08:00:23

In the present day, businesses of all kinds are looking for effective and innovative ways to advertise their products and services. One of the most popular methods used is building facade advertising, which involves displaying banners, signs, or other ads along the outside of a building. This form of advertising is growing in popularity due to its ability to draw attention and make an impact with passersby. It is also relatively cost-effective and can be used in combination with other methods of advertising.
Building facade advertising is a popular and effective tactic for businesses to use when it comes to marketing their products and services. Not only is it visually appealing to customers, but it also offers a larger canvas to work with than traditional ads. This type of advertising is often used to create a sense of familiarity with prospective customers by showing them the brand’s logo in a unique and eye-catching way. Additionally, facade advertising also helps businesses to stand out from the competition by creating an interesting and recognizable presence in their respective marketplace.
Building facade advertising is an effective way to reach a large audience with minimal effort. Utilizing the outside of a building as a platform for advertising can be a creative and attention-grabbing approach. It is also very cost-effective for businesses, as it can help reach customers that may not be exposed to traditional methods. The key to successful building facade advertising is to make sure the message is clear and concise, and to make sure it stands out from the other buildings in the area.
Building facade advertising is an effective way to promote your brand or product. It is a cost-effective form of advertising that can reach a wide audience. When used strategically, building facade advertising can capture the attention of passersby, creating a lasting impression and helping to build brand recognition. Moreover, its flexibility allows for creativity in design, which can be tailored to the specific needs of your business.

1 Next.js Import to Rule Them All in Performance
Tags: nextjs, react, beginners, performance
Published: 2023-12-05 08:08:17

I recently read an article that got me interested in optimizing performance in React web applications.

The article discussed [how we can use Dynamic Imports, Lazy and Suspense for code-splitting](https://dev.to/mursalfk/reacts-dynamic-trio-code-splitting-unleashed-ig9). 

Since I am currently working on a project in Next.js, but I still wanted to implement what I learned as quickly as possible, I looked for how to do the same in Next.js. 

It turned out that its actually much more straightforward in Next. 

In Next.js, you don't need to use React.lazy and Suspense for code splitting, as Next.js handles it automatically through its dynamic imports system.

So here is the code snippet shamelessly copied directly from the React article:
```
import React, { Lazy, Suspense } from 'react';

const MyComponent = Lazy(() => import('./MyComponent'));

const App = () => {
   return (
      <div>
         <h1>My React App</h1>
         <Suspense fallback={<div>Loading...</div>}>
            <MyComponent />
         </Suspense>
      </div>
   );
};

export default App;
```

And here's the same in Next:

```
import dynamic from 'next/dynamic';

const MyComponent = dynamic(
  () => import('./MyComponent'),
  { loading: () => <p>Loading...</p> }
);

const App = () => {
  return (
    <div>
      <h1>My Next.js App</h1>
      <MyComponent />
    </div>
  );
};

export default App;
```

Now all that's left is to see how it actually holds up when the e-commerce web application I am working on, going into production! 

I'm sure there are _loads_(pun intended) of ways how to bring down your site's loading times. But I can only take the burden of learning one way at a time, and this has helped me, maybe this approach can work out for you. 

As a fairly new MERN stack developer, I never really had to optimize for performance per say. But I still want to make my applications snappy. The quest for self-improvement goes on! 

And there is a long, long way to go.

Let me know what other methods would you suggest I should learn both for Next and React web applications.

Happy coding!
