Blockchain technology has been gaining more and more attention and adoption in recent years, and it's poised to continue its growth in 2023. However, like any technology, blockchain has pros and cons that should be considered before fully embracing it.

## Pros of Blockchain Technology:

**Security:** One of the most significant advantages of blockchain technology is its security. The decentralized nature of blockchain makes hacking nearly impossible, as there is no single point of failure. Each block in the chain is verified by multiple nodes, which makes it challenging to manipulate or alter the data.

**Transparency:** Blockchain technology is entirely transparent. All transactions are publicly recorded and verified, meaning everyone on the network can see what's happening. This transparency helps to prevent fraud and corruption, as there is no way to hide or conceal transactions.

**Efficiency:** Blockchain technology eliminates the need for intermediaries such as banks, lawyers, and other third parties. This streamlines the process and can result in faster and more efficient transactions.

**Decentralization:** Blockchain technology is decentralized, which means that any single entity does not control it. This makes it more resilient and less vulnerable to censorship or manipulation.

## Cons of Blockchain Technology:

**Scalability:** One of the most significant challenges facing blockchain technology is scalability. As more and more transactions are added to the blockchain, it becomes slower and more expensive to use. This can be a significant barrier to adoption, particularly in high-volume industries.

**Energy consumption:** Another issue with blockchain technology is the energy required to power the network. The proof-of-work consensus algorithm many blockchains use is incredibly energy-intensive, which can harm the environment.

**Regulatory uncertainty:** Many jurisdictions still need to clarify the regulatory landscape around blockchain technology. This uncertainty can make it challenging for businesses to embrace blockchain fully and may discourage some investors from getting involved.

**Privacy concerns:** While blockchain technology is transparent, some people may be uncomfortable with their financial transactions being publicly visible. While there are privacy-focused blockchains, they are still in their infancy and may not be suitable for widespread use.

In conclusion, 

while blockchain technology has many potential benefits, several significant challenges must be addressed before it can reach its full potential. As with any new technology, it's essential to carefully consider the pros and cons before investing time, money, or resources into blockchain-based solutions.

Are JavaScript and Java the same?
Tags: javascript, java
Published: 2023-03-15 06:03:56

No, JavaScript and Java are not the same thing.

Java is a programming language created by Sun Microsystems in the mid-1990s, and it is used for building applications that run on a variety of platforms, including computers, mobile devices, and servers.

JavaScript, on the other hand, is a scripting language that was originally developed by Netscape in the mid-1990s for use in web browsers. It is used to add interactivity and dynamic content to websites and is primarily used on the client-side (i.e., in the web browser).

Despite their similar names, Java and JavaScript are completely different languages with different syntax, purposes, and use cases.
Tech Equality 🥑👩🏻‍💻
Tags: wecoded
Published: 2023-03-15 05:54:55

The lack of openness and diversity in the tech sector has drawn criticism. It has been difficult for women, people of color, and other underrepresented groups to achieve parity in this field, and it is critical to acknowledge and solve these difficulties. Individuals must commit to embracing equality in tech by taking proactive measures to help and uplift marginalized groups in order to create a more equitable and inclusive tech industry.


I'm going to make the commitment to educate myself on the situations faced by underrepresented groups in the tech sector and to fight for their inclusion and advancement. This entails paying attention to them, raising their voices, and looking for information and education to help one grasp the problems they confront. I can be a more effective ally and supporter of equality in IT by educating myself.
Connect your local resources from inside your Docker Container
Tags: docker, python, containers, database
Published: 2023-03-15 05:47:40

Docker containers are like magic, allowing you to run full fledged applications without going through all the steps and dependencies. The best part is that the experience is same throughout. But sometimes you want to connect to the local resources from inside the container.

## Use case
If you are new to Docker, check out [Creating your first Docker Container - A beginner's Guide](https://dev.to/ag2byte/creating-your-first-docker-container-a-beginners-guide-5a0o). Suppose you have a custom script that creates a database, creates the tables and the relationships and adds data. Since the script may require some dependencies, the best way to ensure that there are no issues for others is to dockerize the entire setup.

## Code Folder Structure

The following is a simple code structure for the above use case.
```
- dbstuff.py
- requirements.txt
- Dockerfile
- requirements.txt
- .env
```

- `dbstuff.py` contains the custom python script that handles all the DML and DDL parts.
- `requirements.txt` has the dependencies used by the project.
- `Dockerfile` contains the layers required to create the image.
- `.env` contains the environment variables which include database connection details
```
DATABASE_USER=devto
DATABASE_PASSWORD=dbpass
DATABASE_HOST=localhost
DATABASE_NAME=devtotest
...
```
## Dockerize the image
Once you create a docker image using `docker build` and run the container using `docker run`, you will face an issue connecting tot the database. This is because the container is trying to connect to the database instance inside it and not on the local machine.


![Normal Connection](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/3fj5w1jrpqqpu7gv2kww.jpg)

## The solution
We need to tell docker to connect to the host's local resources rather than the container's resources. We can do this by changing the .env as follows
```
...
DATABASE_HOST=host.docker.internal
...
```
![Host Connection](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bclomlpxgr8rqgqzm2ta.jpg)
This will now point to the `localhost` of the host. Problem solved!

Create another image and run the container and this should now work as intended! Congratulations 🎉🎉! You have successfully connected to your local Database from inside your docker container

MySQL with Adminer with docker
Tags: docker, dockercompose, devcontainer, developer
Published: 2023-03-15 05:24:12

The way software is developed has been transformed by the emergence of DevOps. Continuous integration and continuous delivery (CI/CD), two DevOps methods, have made it feasible to deliver software more quickly and consistently. We'll discuss Dev Containers, Docker, why it's important to learn Docker, and Docker's benefits in this blog.

## What are Dev Containers and Docker?

Dev Containers are pre-configured development environments that run in Docker containers. Dev Containers are designed to be lightweight and portable, allowing developers to work on their projects without worrying about dependencies or conflicts with their local machine. Developers can easily switch between different Dev Containers, each with its own set of tools and configurations.

## Why it's essential to learn Docker

Docker training is required for any developer who want to work in a modern software development environment. Docker has become the de facto containerisation standard, with millions of developers worldwide using it. Here are a few reasons why learning Docker is critical:

1.  Portability: Docker allows applications to be packaged in containers that can operate anywhere, making it easier to deploy apps across several settings.

2.  Consistency: Docker guarantees that software run reliably across environments, lowering the chance of errors and conflicts caused by different versions of libraries and dependencies.

3. Scalability: Docker makes it simple to scale up or down apps, allowing them to handle increased traffic or strain.

4. Flexibility: Docker's flexibility allows developers to experiment with various settings and environments without affecting their local system.

## Writing the docker compose File

```
version: docker-version

services:
  mysqldb: #image name
    image: mysql:8 # image with what version default is latest
    container_name: mysqldb
    ports:
      - 3306:3306 # port on local machine : port on container
    volumes:
      - mysqlDbVolume:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=SOME_PASSWORD
  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

volumes:
  mysqlDbVolume:
    driver: local
    driver_opts:
      o: bind
      type: none
      device: path/to/local/directorey

```


to access Adminer in browser open localhost:8080

enter image name
user name is root by default
password is SOME_PASSWORD mentioned in docker file
select your DB

then login 


## To run the container 

> `docker-compose up` this will bring your container UP

to stop
> `docker-compose down`

to run as detached add `-d` when you make a container UP


Conclusion

Dev Containers and Docker are essential technologies for modern software development. Docker's portability, consistency, scalability, flexibility, and security make it a key technology for DevOps practices, including continuous integration and continuous delivery. By learning Docker, developers can build, package, and deploy applications with greater efficiency and reliability, making it a valuable skill for any developer to have.

FastKafka - free open source python lib for building Kafka-based services
Tags: webdev, python, fastapi, apachekafka
Published: 2023-03-15 05:18:11

We were searching for something like FastAPI for Kafka-based service we were developing, but couldn’t find anything similar. So we shamelessly made one by reusing beloved paradigms from FastAPI and we shamelessly named it FastKafka. The point was to set the expectations right - you get pretty much what you would expect: function decorators for consumers and producers with type hints specifying Pydantic classes for JSON encoding/decoding, automatic message routing to Kafka brokers and documentation generation.

Please take a look and tell us how to make it better. Our goal is to make using it as easy as possible for someone with experience with FastAPI.

What are filters in context of Conv2d layer?
Published: 2023-03-15 04:55:26

- filter = kernel == weight 
- input_image == feature_map
- applying a filter == 
dot product b/w filter and patch_of_i/p_image
- no of channels in filter or i/p_image == color_scheme of the image/filter

3 color channel => RGB
1 color channel => grayscale


In the context of the Conv2D layer, a filter (also known as a kernel or a weight) is a small matrix of numerical values that is used to extract features from an input image or feature map. During the convolution operation, the filter is applied to each position of the input image or feature map, and a dot product is computed between the filter and the corresponding patch of the input. The result is a single scalar value, which is used to generate an output feature map.

Filters are typically learned during the training process of a neural network. The weights of the filters are adjusted to minimize the difference between the predicted output of the network and the true output, using a loss function and an optimization algorithm such as stochastic gradient descent.


Conclusively,
filters contain weights of edges/connections b/w 2 neurons of adjacent layer (L1 => L2)

![Lumigo Buzzwire game](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zftt0emim9tt54has6rk.png)

The IoT trace wire game that I shared with the audience was an exciting project that Lumigo used in our booth for re:Invent last year. The game involved players navigating through a wire maze as quickly as possible, with their times recorded and sent via WiFi to a Lambda function and stored in DynamoDB. This allowed us to trace the entire process using Lumigo, demonstrating the power and usefulness of serverless computing.

The game was a real challenge to build, requiring a lot of logistical planning and work pivots, as well as extensive tinkering with IoT hardware and 3D printing. But the end result was a lot of fun for everyone involved, including myself. If you're interested in learning more about my experience building this game and how we used Lumigo to trace it, be sure to check out my blog post on Observing IoT and Lambda.

Join us in celebrating the serverless community spirit and the hardworking team that made this event possible.
