Facing Issues
Published: 2023-10-07 04:55:07

Hello GoodDay,

I recently became a part of this community because I'm on a journey to improve myself. I'm actively seeking a job and have been learning React through various tutorials on platforms like YouTube and Udemy. However, despite my efforts, I've been struggling to secure my first job. During job interviews, I often encounter challenges when interviewers present me with problems to solve. While I attempt to solve them during the interview, I sometimes struggle to come up with the best logic for the task. It's frustrating because, after the interview, I often find solutions on Google that make me realize the questions were relatively straightforward.

I would greatly appreciate your guidance on how to overcome these issues and become a better programmer.

Best regards,
Daniel

Python Selenium Architecture
Published: 2023-10-07 04:26:42

Selenium is an open source automated testing framework used to validate web applications and performing browser automation which works on all major Operating Systems and can be written in any many programming languages like Python, Java, C# etc.

Selenium with Python is widely used due to the following reasons:

- Selenium is open source and portable testing framework
- Selenium is a combination of tools and Domain Specific Language in order to carry out various tests.
- Selenium commands are divided in terms of different classes which makes it easy to understand and implement.
- The amount of time required to do testing repeated test scenarios on each and every new build is reduced to zero.
- Python is dynamically typed, object oriented and functional programming and can serve as scripting language for web applications which makes it very convenient to work with Selenium.

**Python Selenium Architecture:**
Selenium WebDriver Architecture is made up of four major components:

Selenium Client library: Selenium supports multiple libraries such as Ruby, Python, Java, etc as language bindings

JSON wire protocol over HTTP: JSON full form is JavaScript Object Notation. It is an open standard that provides a transport mechanism for transferring data between client and server on web.

Browser Drivers: Selenium browser drivers are native to each browser, interacting with the browser by establishing a secure connection. Selenium supports different browser drivers such as ChromeDriver, GeckoDriver, Microsoft Edge WebDriver, SafariDriver, and InternetExplorerDriver.

Browsers: Selenium provides support for multiple browsers like Chrome, Firefox, Safari, Internet Explorer etc

                   In Selenium 3, there is no direct communication between the client libraries (Java, Python, JavaScript, etc) and the browser drivers. The server (browser drivers) does not understand language but only the protocols and on the other hand, client libraries does not understand protocols used by browser drivers. 

Therefore, JSON Wire protocol is being used as a mediator between client and server to encode and decode the requests and responses made by client and server respectively. This results in limited browser interaction, inefficient communication and lack of standardization.
So, Selenium 4 WebDriver was made W3C compliant to make the communication easy and direct between the client libraries and the browser drivers. Improved communication led to more stability.

Collaborative Git Workflow: Learning git fetch and git pull
Published: 2023-10-07 04:09:30

In this blog post, I'm going to share my developing process about git fetch and git pull in the process. We will also discuss how git fetch allows us to safely test and review code from others.

When reviewing and testing a PR, you might need to work with a different repo that you didn't clone originally. How can you do this? The answer is `git fetch`.

Assuming Bob is working on the forked repo, you can add their fork as a remote to your local repo:

```
git remote add Bob https://git-url-of-Bob-fork.git
```
Here I assigned the remote name as 'Bob' for his fork's URL, you can  choose any name you prefer.

With this remote added, you can fetch his work into your local repo:

```
git fetch Bob
```

`git fetch` downloads all their commits and branches to your local repo but doesn't automatically merge anything. This is crucial because it won't interfere with your current branch or code.

Next set up a tracking branch in your local repo, so you can track the work on Bob's branch:

```
git checkout -b <branch-name> Bob/<branch-name>
```

This creates a branch in your repo that points to the same commit as the Bob's repo and branch. You can now use this branch to review and test Bob's work.

If Bob make updates to their code, you can easily fetch these changes into your tracking branch:

```
git checkout <branch-name>
git pull Bob <branch-name>
```

At last once you're satisfied that the feature, we can merging it manually by
```
git fetch Bob
git checkout main
git merge Bob/<branch-name>
git push origin main
```

Note that merging the work and pushing it to the main branch will automatically close the pull request.

To sum it up, Git's adaptability and strength prove incredibly beneficial when engaging in collaborative projects. The use of git fetch allows you to examine and evaluate others' code without interfering with your own work. If you haven't used it before, give it a try!
Generate your own VS Code snippets faster by csnp
Tags: vscode
Published: 2023-10-07 03:56:07

## Introduction

**csnp** is a node script written by typescript

Based on VS Code built-in customizable code snippets[（official documentation introduction）](https://code.visualstudio.com/docs/editor/userdefinedsnippets)

Give developers the ability to create VS Code snippets quickly and easily


## Usage Scene

In your code file, use the command `-log` and press enter to generate the code `console.log('-> log', _)`（ *_ is the position of the cursor*）

In the .code-snippet file of VS Code

- command `-log` represents a prefix

- codes `console.log('-> log', _)` represents a body

The **csnp** command can generate the log.csnp file quickly, which can be managed by markdown friendly syntax and generated under the root path of the project

exp: *.vscode/.csnp/js/log.csnp*

The **js** of the path in **csnp** is stand for csnp type

## Easy Start

```bash
# 1. install global
$ npm i -g csnp

# 2. init csnp file
$ csnp

# 3. open csnp file，edit your own code snippets

# 4. generate code snipepts
$ csnp push
```


## .csnp File

```md
---
name: Log
prefix: '-log'
description: log sth
---
console.log('-> log', $1)
```

The log.csnp will converts the js.code-snippets file by executing the 'csnp push' command, then you can use the '-log' command.

## .code-snippets File

The js.code-snippets file is a piece of json, and VS Code will automatically parses the file with this suffix file.

```json
{
  "Log": {
    "prefix": "-log",
    "body": [
      "console.log($1)"
    ],
    "description": "log sth"
  }
}
```

## End

If you think csnp helpful, thanks for your star ⭐️ ~

Amazon RDS Blue/Green Deployments 4 DB updates
Tags: deployments, aws, bluegreen, dbupdates
Published: 2023-10-07 03:42:46

**A blue/green deployment copies a production database environment to a separate, synchronized staging environment. **By using Amazon RDS Blue/Green Deployments, you can make changes to the database in the staging environment without affecting the production environment. 

For example, you can **upgrade** the major or minor DB engine version, change database **parameters**, or make schema changes in the **staging** environment. When you are **ready**, you can **promote** the **staging** environment to be the new **production** database environment, with downtime typically under one minute.

By using Amazon RDS Blue/Green Deployments, you can create a blue/green deployment for managed database changes. **A blue/green deployment creates a staging environment that copies the production environment.** In a blue/green deployment, the **blue environment is the current production** environment. The **green environment is the staging **environment. The staging environment stays in sync with the current production environment using logical replication.

You can make changes to the RDS DB instances in the green environment without affecting production workloads. For example, you can upgrade the major or minor DB engine version, change database parameters, or make schema changes in the staging environment. You can thoroughly test changes in the green environment. When ready, you can switch over the environments to promote the green environment to be the new production environment. The switchover typically takes under a minute with no data loss and no need for application changes.

Because the green environment is a copy of the topology of the production environment, the green environment includes the features used by the DB instance. These features include the read replicas, the storage configuration, DB snapshots, automated backups, Performance Insights, and Enhanced Monitoring. If the blue DB instance is a Multi-AZ DB instance deployment, then the green DB instance is also a Multi-AZ DB instance deployment.

2023-10-06: Another one bites the dust
Tags: devjournal
Published: 2023-10-07 03:29:57

The theme of this week has been LangChain. As I said last time, I was planning on converting my old script into a LangChain script.

I had the initial idea of sketching out the dataflow in Figma to see how I could try crafting the langchain but it turned out to be a little more difficult than I'd thought.

I have a major design problem of how to actually keep a rotating "inventory" to make sure the data is actually varied as it's being generated. Originally, the way I had the script, it would just do ten example user inquiries in a single shot, and then I'd ask it in a separate step to then refine those generated inquiries to make them more varied. This kind of approach works fine, naively, but it's pretty inefficient and also results in the AI using the same general pattern for every single one.

In my head, I was thinking that perhaps it would allow for some more creativity for it to actually take steps in generating the content, which was a perfect use case for LangChain, since, as the name implies, it has the ability to chain LLM prompts.

My goal then was to generate one inquiry, save it to a file, keep it in memory, then pass it back into the chain to generate another one. Every time it does this, it can use fresh eyes to evaluate what it wrote last time instead of doing it all in one shot. This is a common failing with LLMs; it will get sidetracked on generating the most "probable" answer given the prompt, and not evaluate its own responses until expressly stated.

I am also expecting that this approach may be a tad faster in terms of turnaround time to create something, but it may also take longer. I will have to do some timed trials to see.

At the moment, I am still trying to figure out how to actually get this accomplished through the code I have set up. It's definitely more difficult than usual because LangChain is new and obviously ChatGPT can't do the designing for me. I have to do it all the old-fashioned way, and it's wracking my brain.

There is also a separate closed beta platform that LangChain has called LangSmith which seems to be a vector store database thing which will make classifying and retrieving our data for our models though LangChain much easier and streamlined, but we were having trouble today getting it to actually log stuff, which is a core feature.

In other news not directly related to coding, my coworker apparently was fired due to dishonesty in how much work he was actually putting out, so that's fun. I hope we can find a replacement soon because it sucks that we have to pick up the pace even more than we already have been.

Anyway, until next week, cheers.
