DevEx 101: Looks Good To Me
Tags: devex, codereview
Published: 2023-06-08 12:53:45

When and where I started my career we had no automated code checks. When I opened a change request to our code, I had to ask two of my colleagues to review the change and it usually came back with a list of typos to fix, functions in need to break up, formatting problems, requests for explanation and the final boss of comments _let's talk about this_.

Time passed by, the number of comments went down and usually I only got a single message saying 'LGTM'.

I could say I was a perfect programmer and learned one or two things about spelling words right, but what really happened was my colleagues letting their guards down on smaller mistakes. It's trust. It's beautiful. And it made me a couple of long shifts fixing uncaught bugs.

---

## Now I think we do code reviews for all the bad reasons.

---

### All The Bad Reasons

#### The PR has to have at least X approvers
Oh those company guidelines! We ask for review because we have to ask for review so we end up with a rubber stamp and not learning anything. Usually the approver doesn't even know that part of the software very well, or is too busy to be bothered.

_- Recommend Reviewers: Create groups of people familiar with certain services or parts pf code. Don't assign everyone of every part of the code, unless it's common domain._
_- Time to Review: Create tags with estimation on how much time it takes to review the PR. I bet PRs with 5-15 minutes review time won't get stale as 45min monsters do._
_- Similar PRs: If you have to update configuration in multiple repos, group the changes!._

#### I'm not sure this will work
Could be lack of confidence in self or in the system, anyways, you need to talk about the testing strategy.

_- Start with tests covering the existing features that might break._
_- Test on an ephemeral environment._

#### Does this fit the code aesthetic
Code aesthetics, typos, grammar or formatting should not be part of the reviewers job but it often still is.

_- We are lucky we can implement automated PR checks to run linter, grammar scanner or anything we agree on before even asking a human for feedback. For this, you need to hold the addition of reviewers until all automated checks ran._

---

### All The Good Reasons 

#### I want to talk about my solution

#### The code feels incomplete or could probably be improved

#### I have concerns about nearby code

#### I rebased my branch and I want to know if something relevant changed

---

Anything can be a good reason until it starts an interesting conversation or pushes us towards smarter solutions. Just don't forget to spend your time with meaningful reviews and automate the boring stuff.

How to make an empty commit in Git?

Empty commits might seem like a strange and unnecessary thing, but they can actually be helpful.

For example, if you need to restart a pipeline, an empty commit can be just what you need to get it up and running again. 

So how do you make an empty commit in Git? It's actually quite simple. 

Just use the command

`git commit --allow-empty -m 'your commit message here'`

and voila!

You've made an empty commit. Now you can push it to remote, if necessary.

How To Use OpenAI’s ChatGPT API In NodeJS
Tags: node, openai, chatgpt, development
Published: 2023-06-08 12:31:17

Chatbots have made it possible for us to communicate with machines in ways that our forefathers could never have imagined. They represent one of the best instances of how far artificial intelligence has progressed and has completely changed the way we interact with technology.

**What is OpenAI’s ChatGPT?**

The large-scale language model ChatGPT was developed by the renowned AI research company OpenAI. On a sizable amount of both structured and unstructured data, it was developed and taught utilizing an unsupervised learning methodology. The creation of a chatbot that can better understand and respond to customers' natural language questions is the main objective of this research and development.

**What is NodeJS?**

Developers may use JavaScript to create server-side programming thanks to NodeJS. This framework is based on Chrome's V8 JavaScript engine, which was created in C++ for lightning-fast performance. Additionally, it has an IO model that is event-driven and non-blocking and is appropriate for real-time and data-intensive applications.

**Why Use NodeJS?**
1. Superfast Execution
2. Real-time Performance
3. Memory Efficient
4. Single Language in Frontend and Backend
5. Node Package Manager

**Building a Chatbot in NodeJS with ChatGPT API**
1. Starting with the Imports
2. Creating an Async Wrapper
3. Creating the Configuration and API Setup
4. Setting Chat History
5. Creating the Chat Loop
6. Getting User Input
7. Creating Chat History
8. Initializing the AI Model
9. Getting Model’s Response and Adding to History
10. Ask for Conversation Continuation

Using the OpenAI API, a straightforward chatbot may be created in NodeJS. To make the chatbot even more user-friendly, a frontend can be created using any frontend framework. Hope this is useful! If you run across any problems when building the chatbot, let us know in the comments section below. [this is an in-depth article](https://knotsync.com/how-to-use-openai-chatgpt-api-in-nodejs/) that will help you in getting complete information related to using OpenAI’s ChatGPT API In NodeJS.
Handle Same key Validation

ধরি কোন প্রাপার্টি যদি আগে থেকেই থাকে তাহলে সেটা পুনরায় আবার এন্ট্রি দেওয়া যাবে না, এর জন্য একটা Validation করতে হবে। কোন ইউজার যদি এড করতে চায় তাহলে সে একটা এরর থ্রূ দেখতে পাবে। 

ধরি ডাটাবেসে একটা অব্জেক্ট আছে এরকমঃ

{
”name”: “Salim Al Sazu”,

"position": “Web Developer”
}

সেইম নামে আরেকটা যদি পোস্ট করতে চাই তাহলে সে এরর দিবে। এখন কোডে আসা যাকঃ

এখন এই ভ্যালিডেশনটা আমরা কোথায় করবো, রাউটারে, কন্ট্রলারে নাকি সার্ভিসে ? না মডেলে …… ? 

মঙ্গুজে দুই ধরনের হুক আছে একটা প্রি আরেকটা পোস্ট, প্রি মানে ডাটা সেভ করার আগে চেক করে আর পোস্ট ডাঁটা সেভ করার পর। 

এখন প্রি হুক দিয়ে চেক করে নিবো যদি কোন ডাটা না থেকে তাহলে পোস্ট করবে, না হলে এরর থ্র করবে । 

নরমালি যেভাবে স্কিমা নেওয়া হিয় সেভাবে একটা স্কিমা নিবোঃ 

```
const UserSchema= new Schema(
  {
    name: {
      type: String,
      required: true,
    },
    position: {
      type: String,
      required: true,
    }
  },
  {
    timestamps: true,
  }
);
```

স্কিমা নেওয়া হিয়ে গেলে সেটার উপর মঙ্গুজ এর pre-hook  চালাবোঃ

যেহেতু স্কিমা নেইম UserSchema তাহলে এটা দিয়ে pre ফাংশন বলে দিবো UserSchema.pre() তারপর pre  এর ভিতর 'save', async function { }নিবো । এই ফাংশনের ভিতর isExist ভ্যারিয়েবল নিয়ে একটা findOne চালাবো মডেলের নাম এর উপর (মডেলের কোড নিচে দেওয়া আছে )। 

findOne বলে দিবো যদি এই ডাটা গুলো খুজে বের করো এইভাবে findOne({
    name: this.name,
    position: this.position,
  });

খুজে বের করা পর একটা কন্ডিশিন দিবো যদি এই গুলো  

তারপর একটা কন্ডিশন দিবো যদি এই গুলো  isExist করে তাহলে এরর দাও কনফ্লিক্ট এর ।  

if (isExist) {
    throw new Error(409, 'User is Already Exist');
  }

আর যদি কনফ্লিক্ট না করে তাহলে  next() ফাংশন চলে যাও , যা মঙ্গুজের আরেকটা হুক , এক্সপ্রেস এর নয় । 

```
UserSchema.pre('save', async function (next) {
  const isExist = await Users.findOne({
    name: this.name,
    position: this.position,
  });

  if (isExist) {
    throw new Error(409, 'User is Already Exist');
  }
  next();
});
```

এখন যদি লিখা হয়ে যায় তাহলে  মডেল  যেভাবে লিখে সেভাবে লিখে ফেলবোঃ

```tsx
export const Users= model(
  'user',
  UserSchema
);
```

মডেল ক্রিয়েট হওয়ার আগে আমাদের সেইম ডাটা আছে কি না তা চেক করা লাগবে তাই প্রি হুক মডেলের উপরে ইউজ করা হয়েছে। যদি মডেলের পরে ব্যবহার করা হয় তাহলে সে চ্যাক না করে সেইম ডাটা পাঠিয়ে দিবে। 

এখানে সার্ভিস, কন্ট্রলার , রাউট এই গুলো জানা আছে বিদায় আমরা সেইম ডাটা এরর হ্যনাডেলিং নিয়ে আলোচনা করেছি তা এই গুলো নিয়ে এখানে কথা বলা হয় নাই।

Tags: blockchain, cryptocurrency, web3, distributedsystems
Published: 2023-06-08 12:04:57




Blockchain is a term that’s been buzzing around in recent years, but what exactly is it? In simple terms, blockchain is a decentralized digital ledger that records transactions across multiple computers. Here’s a breakdown of this groundbreaking technology:

**- Transparent and Immutable**: Blockchain provides transparency by allowing everyone on the network to see the same information. Once a transaction is recorded, it cannot be altered or deleted, ensuring the integrity of the data.

**- Decentralized and Secure**: Unlike traditional centralized systems, blockchain operates on a decentralized network. This means there’s no single point of failure or vulnerability to hacking. Data stored on the blockchain is protected by advanced cryptographic algorithms, making it highly secure.

**- Smart Contracts and Automation**: Blockchain allows for the creation of smart contracts, which are self-executing agreements with predefined rules. These contracts automatically trigger actions when specific conditions are met, eliminating the need for intermediaries and streamlining processes.

**- Efficiency and Cost Savings**: By removing intermediaries and automating processes, blockchain increases efficiency and reduces costs. It eliminates the need for manual record-keeping, paperwork, and reconciliation, resulting in faster transactions and lower operational expenses.

**- Versatility Beyond Cryptocurrencies**: While blockchain gained popularity through cryptocurrencies like Bitcoin, its applications go beyond digital money. It can be used in various industries such as supply chain management, healthcare, voting systems, and more, enhancing transparency and trust.

**- Potential for Disruption**: Blockchain has the potential to revolutionize industries by disrupting traditional systems. Its decentralized nature and trust-building capabilities can transform business models, enabling new opportunities and empowering individuals.

In conclusion, blockchain is a transparent, secure, and decentralized technology that offers numerous advantages. From enhancing transparency and efficiency to enabling automation and cost savings, its potential is vast. As we embrace this transformative technology, we can expect to see significant changes across various sectors, unlocking new possibilities for a more connected and secure future.
