Hello Python Developers! 👋✨

Let's explore some Pythonic tips and tricks to enhance the elegance of your code. 🌟

1.**The Zen of Python:**
   - Follow the Zen of Python. Run `import this` in your Python interpreter to discover the guiding principles that make Python code beautiful.

2.**List Comprehensions Mastery:**
   - Condense loops into powerful one-liners with list comprehensions. Clean, concise, and Pythonic!

   ```python
   squares = [x**2 for x in range(10)]
   ```

3.**Zen and the Art of `zip`:**
   - Harness the power of `zip` to seamlessly combine and iterate over multiple lists.

   ```python
   names = ["Alice", "Bob", "Charlie"]
   ages = [25, 30, 22]
   zipped_data = list(zip(names, ages))
   ```

4.**Dictionary Unpacking Magic:**
   - Unpack dictionaries effortlessly for efficient merging or updating.

   ```python
   dict1 = {"a": 1, "b": 2}
   dict2 = {"b": 3, "c": 4}
   merged_dict = {**dict1, **dict2}
   ```

5.**The Art of `enumerate`:**
   - Embrace the versatility of `enumerate` for index-value pairs during iteration.

   ```python
   for index, value in enumerate(["apple", "banana", "cherry"]):
       print(index, value)
   ```

6.**Context Managers for Code Hygiene:**
   - Utilize `with` statements for cleaner code and effective resource management.

Exporting a large PostgreSQL table using Python
Tags: webdev, postgres, python, sql
Published: 2023-10-16 03:46:13

When working with large datasets, it's common to extract PostgreSQL tables to CSV files for further analysis and sharing. However, naively exporting a large table can crash your machine by consuming all available RAM.

In this article, I'll explain an efficient technique to export big PostgreSQL tables to CSV using Python, based on my experience as a Research Assistant analyzing criminal record relief data.

## The Naive Approach
You can export a table like this:

```python

# Execute a SELECT query 
cursor.execute("SELECT * FROM employee")

# Fetch all rows 
rows = cursor.fetchall()

# Write rows to CSV
with open("employees.csv", "w") as f:
  for row in rows:
    f.write(",".join([str(cell) for cell in row]) + "\n")
```
However, this loads the entire table into memory - which will crash your machine for a big table!

## Streaming Data in Chunks with psycopg2
The key is to stream the data in chunks from the database directly to disk. The psycopg2 module provides a handy COPY method that lets us do just that.

First, connect to the database and open the output CSV:

```python

import psycopg2

conn = psycopg2.connect("dbname=mydb user=postgres")

with open('out.csv', 'w') as f:
```
Next, use copy_expert() to stream the table to the file in chunks:

```python
  cur = conn.cursor()
  
  cur.copy_expert('COPY employee TO STDOUT WITH CSV HEADER', f)
```
The table is streamed to the CSV without loading everything into memory!

Putting It All Together
Here is the full script to efficiently export a large PostgreSQL table to a CSV:

```python
import psycopg2

conn = psycopg2.connect("dbname=mydb user=postgres")

cur = conn.cursor()

with open('out.csv', 'w') as f:
  cur.copy_expert('COPY employees TO STDOUT WITH CSV HEADER', f)
print("Table exported to CSV!")
```
By streaming the data in chunks directly to a file, we avoid RAM issues and efficiently export the table.

## Extracting results of SQL query

The above method copies all the data from the `employee` table to a CSV file. But if you want to store the results of a query with the above method you will have to modify it slightly as below.

```python
import psycopg2

conn = psycopg2.connect("dbname=mydb user=postgres")

cur = conn.cursor()

# list of departments from which we want all employees
dept_list = ['dept1', 'dept2']

query = """SELECT *
        FROM employee
        WHERE department IN %s"""

query_params = (tuple(dept_list),)

query = cur.mogrify(query, query_params)
query = query.decode('utf-8')

with open('out.csv', 'w') as f:
  cur.copy_expert("COPY ({}) TO STDOUT WITH CSV HEADER".format(query), f)
print("Query results exported to CSV!")
```

This technique has helped me quickly extract large criminal record relief datasets from PostgreSQL databases for analysis. Let me know if you have any other tips and tricks!
Argo CD - Declarative GitOps CD for Kubernetes
Tags: argocd, kubernetes, gitops, software
Published: 2023-10-16 03:19:00

Yesterday, a friend asked me about tools to use for pipeline, and I suggested Argo CD, which is a declarative GitOps continuous delivery (CD) tool for Kubernetes. It enables developers to manage both infrastructure configuration and application updates in one system. Argo CD is built following the Kubernetes Operator Pattern, which means that it is a lightweight, reusable controller that can be used to manage any type of Kubernetes resource.

**What is GitOps?**

GitOps is a software development practice that uses Git as a single source of truth for all infrastructure and application configuration. This means that all changes to infrastructure and application state are made through Git commits and pull requests. Argo CD implements GitOps by continuously monitoring the desired state of an application in Git and the actual state of the application in Kubernetes. When the desired state and actual state differ, Argo CD automatically deploys the desired state to Kubernetes.

**Benefits of using Argo CD**

Argo CD offers a number of benefits over traditional CD tools, including:

* **Declarative approach:** Argo CD uses a declarative approach to deployments, which means that developers only need to specify the desired state of their application in Git. Argo CD will then take care of deploying the application to Kubernetes and ensuring that it remains in the desired state.
* **Git as a single source of truth:** Argo CD uses Git as a single source of truth for all infrastructure and application configuration. This makes it easy to track changes and roll back deployments if necessary.
* **Continuous deployment:** Argo CD continuously monitors the desired state of an application in Git and the actual state of the application in Kubernetes. This allows for continuous deployment, which means that developers can deploy changes to their application to production with confidence.
* **Auditability:** Argo CD tracks all changes to infrastructure and application configuration in Git. This makes it easy to audit changes and troubleshoot issues.

**How to use Argo CD**

To use Argo CD, you will first need to install it on your Kubernetes cluster. Once Argo CD is installed, you can create an Applicatinpm starte to Kubernetes.

**Conclusion**

Argo CD is a powerful GitOps CD tool that can help you to automate and simplify the deployment and management of your Kubernetes applications. If you are looking for a way to improve your DevOps workflow, Argo CD is a great option to consider.

Differences Between textContents, innerText, and innerHTML and When to Use What.
Tags: programming, javascript, beginners, tutorial
Published: 2023-10-16 02:44:49

   You would think textContents, innerText, and innerHTML would work the same way in JavaScript. There are so many ways to accomplish the same thing while coding, that this is just another. You would be wrong, all three of these render different output when using them. 

Here’s an example of some simple HTML with some inline CSS:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/seaaa7v913mora4vigit.png)

Here is what that looks like opened up in the browser:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4h8kp3zy8nc2d5dljfsc.png)

   As you can see the word ‘emphasized’ is in italics and the word ‘code’ monospaced. For those wondering monospaced means all or most the characters take up the same amount of horizontal space. In a console we set a const to our div and call that const with ‘.innerHTML’:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/9j7ek4u2l9322l1h0lci.png)

   Using innerHTML shows you everything in the HTML markup contained in a string. This includes elements like spacing, line breaks and formatting. As you can see in the example above we see the <em></em> tags around the word emphasized making the word italic, we are also shown the 6 spaces between ‘emphasized’ and ‘and’, and lastly we see the <code></code> tags. You should only use innerHTML when you want to see the HTML markup and what is in the element.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/moxs4idt0ukmibkg136b.png)

   Using innerText returns the string inside the div, it renders the text content of a node and knows about the styling and CSS. In the example above we again set the div to a const and then call it with ‘.innerText’. The return is exactly the same as it appears in the browser. You do not see the spacing oddity or the <em> and <code> tags. Use innerText when you only want to see the element.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2jbvv85psrwj4r3xu3xd.png)

   TextContent returns content of all elements in the node. Its aware if script and style elements, also formatting like spacing and line breaks. In the example above we set the div to a const and call on it with ‘.textContent’. The return is almost as it appears in the browser with the exception of the spacing. You should use textContent when you want to see what in an element plus any styling.

   Some additional notes, in innerHTML if the text inside the element includes ‘&’, ‘<’, or ‘>’ they will be returned as HTML entities ‘&amp’, ‘&lt’ and ‘&gt’. Using innerText sets the content of the tag as plain text, in innerHTML it retrieves and sets the content in HTML format. The difference between innerText and textContent is that innerText is aware of it’s appearance and textContent is not.
Practicing subdomain route in local environment with laravel
Tags: laravel, php
Published: 2023-10-16 02:41:25

Subdomain route is a less used feature in laravel as most of the laravel applications are hosted under one single domain. But the feature is available in laravel.

A friend of mine requested to write an article about how he can set up his local environment to test this subdomain routing, and I thought It will be better if I just document it 🙃.


## Setting UP DNS
First of all we need to set up DNS such a way that every subdomain points to one single host. [A wildcard entry](https://en.wikipedia.org/wiki/Wildcard_DNS_record) is enough for DNS server but wildcard is not supported in local host file.
We need to manually entry every subdomain in host file.
Host file path is different based on Operating System,
In windows : `C:\Windows\System32\drivers\etc\hosts`
In Linux : `/etc/hosts`
In Mac : `/private/etc/hosts`
> We must have elevated privilege to edit host file, In windows we need to edit this file as Administrator, in linux use sudo or root user

As example I am using `laravel.test` as main domain,
In host file, add those entries
`
127.0.0.1 laravel.test
127.0.0.1 one.laravel.test
127.0.0.1 two.laravel.test
127.0.0.1 three.laravel.test
`

## Setting up Route

In laravel, we just need to add a domain route to capture subdomains.
In, `routes/web.php`
```php
Route::domain('{subdomain}.laravel.test')->group(function () {
    Route::get('/', function (string $subdomain) {
        return $subdomain;
    });
});
```

Now, if we start laravel app and brows `http://laravel.test` it will ignore subdomain route as it is not a subdomain, but if we brows `http://one.laravel.test` it will return only the subdomain.

Port number won't effect routing. If your application is running on port **8000**, you can hit the subdomain route by browsing `http://one.laravel.test:8000`.

One thing to keep in mind, (from laravel official documentation)
>In order to ensure your subdomain routes are reachable, you should register subdomain routes before registering root domain routes. This will prevent root domain routes from overwriting subdomain routes which have the same URI path.

Now you know what to do next, Artisan
Happy coding !!!

> GPT-4V는 9월 24일부터 출시 OpenAI ChatGPT iOS 앱과 웹 인터페이스 모두에서 사용가능

> 도구를 사용하려면 GPT-4 구독

###테스트

1. 시각적 질문 답변
2. 광학 문자 인식(OCR)
3. 수학 OCR

5. 보안 문자


###제한및안전

> 누락된 수학 기호
> 공간적 위치와 색상을 인식하지 못함


###비전

GPT-4V는 기계 학습 및 자연어 처리 분야에서 주목할만한 움직임입니다. GPT-4V를 사용하면 자연어로 이미지에 대해 질문하고 후속 질문을 할 수 있으며 모델은 질문을 시도합니다.

GPT-4V는 다양한 일반 이미지 질문에서 좋은 성적을 거두었으며 테스트한 일부 이미지에서 상황에 대한 인식을 보여주었습니다. 예를 들어, GPT-4V는 영화가 무엇인지 텍스트로 알려주지 않고도 이미지에 등장하는 영화에 대한 질문에 성공적으로 답할 수 있었습니다.

일반적인 질문 답변의 경우 GPT-4V가 매우 흥미롭습니다. 과거에는 이러한 목적을 위해 모델이 존재했지만 답변이 유창하지 못한 경우가 많았습니다. GPT-4V는 이미지에 대한 질문에 답변하고 후속 질문을 심층적으로 수행할 수 있습니다.

GPT-4V를 사용하면 2단계 프로세스를 만들지 않고도 이미지에 대해 질문할 수 있습니다(즉, 분류한 다음 그 결과를 사용하여 GPT와 같은 언어 모델에 질문하는 것). GPT-4V가 이해할 수 있는 것에는 제한이 있을 수 있으므로 모델의 성능을 이해하기 위해 사용 사례를 테스트하는 것이 중요합니다.

하지만 GPT-4V에는 한계가 있습니다. 모델이 "환각"을 하여 부정확한 정보를 반환했습니다. 이는 질문에 답하기 위해 언어 모델을 사용할 때 위험합니다. 게다가 모델은 객체 감지를 위한 경계 상자를 정확하게 반환할 수 없었으며 이는 현재 이 사용 사례에 적합하지 않음을 나타냅니다.

우리는 또한 GPT-4V가 사람에 관한 질문에 대답할 수 없다는 사실도 관찰했습니다. 테일러 스위프트의 사진을 제시하고 사진 속 인물이 누구인지 묻자 모델은 답변을 거부했다. OpenAI는 이를 게시된 시스템 카드에서 예상되는 동작으로 정의합니다.

Ugg can't believe I'm a noob once again in a new field asking noob questions.

Here goes...

I consider myself an intermediate html/css coder (learned the basics back in 1999 and had some front end jobs 1999-2005 before getting into marketing).

I've hired a few devs to help me make some projects but I want to learn to code up my own CRUD apps. I'm real good marketing them but not so much yet building them.

I'm kinda turned on by the JS/React/Node vibe. Started taking a course at freecodecamp. Besides reading articles from dev.to what else should I be using to learn my way into the semi-literate javascript world?
Thx!

Interaction Issue between Apache's ETag Return and Accept-Encoding
Tags: discuss, apahche, webserver, cache
Published: 2023-10-16 01:13:51

Hello, I am encountering an issue related to the ETag return while using Apache and am hoping to get some insights from the community.

In my server environment, when the HTTP Request Header contains Accept-Encoding: gzip, deflate, Apache appends a "-gzip" suffix to the ETag in the response, turning it into "12345-gzip". However, when I send another request to the same resource with "If-None-Match: 12345-gzip" in the headers, Apache responds with a status code of 200 instead of the expected 304.

On the other hand, if I adjust the Request Header to "If-None-Match: 12345", then Apache responds with a 304 status code, which is as expected.

I searched online and found some discussions suggesting that this might be a bug in Apache. However, I would like to further confirm and understand if anyone else has faced a similar issue and how they resolved it. Does anyone have any recommendations or solutions to offer? Much appreciated!
