Is there a specific type or style of computer that you really like? And what kind of coding software are you proficient in?

My ideal dream computer setup would definitely be an old 2000's-esque computer running Windows XP, with an old CRT monitor and all. <333 However, that's unfortunately not very possible, due to Windows XP having had no security updates ever since 2014 or so. So it's not a very safe operating system to use anymore (unless it's fully offline and not connected to the internet without antivirus etc), which is depressing as it's my all-time favorite one </3 I really love the look of them old beige bulky computers from the 1990's and early 2000's, they're so nostalgic <333

And when it comes to coding, I can't say that I'm skilled or proficient in any program yet as coding generally is pretty new to me still. But I've lately been using CLion for C++ coding, WebStorm for HTML/CSS coding and Visual Studio Code for nearly everything else. In school, we use different programs, like for example; QtCreator, XAMPP (MySQL stuff in shell) and uhhhh, Visual Studio etc. I've gotten to use a lot of programs, lol.

If I had to recommend a good program for coding itself; Visual Studio Code, Notepad++ (for Windows only) and JetBrains programs are good solid ones imo.

Preparation for the study

Hello guys!

Well, I've been doing a course of java in the past week or so, but I haven't been tracking and I want to keep a progress to be more sure I am in a good pace and will end it (kinda) faster.

So today I am going to pick a schedule and turn it into a habit, also I am going to organize how I will spend my time studying. I am learning Java (still on the very beginning heelp). So far, have made into 55 of 541 videos in the Java course, 77 hours of lessons and there's also practice and some challenges to do. I don't think I am able to get it done if I don't put my effort into being aware of my time, so my biggest flaw here is to keep focus and avoid procrastination at all my costs.

The course abt java has:

-Fundamentals of Java

-Programming oriented object

-Functional programming

-Mysql

-Mongodb

-Spring boot

-Javafx

-JPA

-Hibernate

And when I end this course I will continue with the ""sequel"", my point is to keep learning so I can get a job at the field and move on into being able to buy more books and keep this looping going. As the obsessive I am, I'm fully engaged in tech obviously, so my plans much depends on learning about it, and then how to make everything in my life about it too so... Yeah it will be fun, and a big stress probably. Hope I don't burn my head doing that.

Also, I bought last week a few other courses, cuz they were for such a good price I couldn't say no. Still haven't picked any of them to study, but, respectively they are:

-HTML and Css basics

-Terminal for beginners

-Gnu nano

-Shell script advanced

-Learn to compile

-VPS Server

-Create your own package manager

-Vagrant

-Slackware essentials

-Darkweb

Those are some topics I am interested in, even knowing a little about one here and there, will be a great challenge to advance my comprehension. I need to find time to put them into schedule. Wish me luck everybody. Maybe I am getting too overwhelmed to do everything I picked? Of course, but fuck it I can handle - just not at the same time obviously, sometime I will get there I just need to be patient with myself and keep consistency at check.

Gosh, was a long post huh? I will say later on my plan to get it all done! Until them, thank you for staying with me.

Using Docker in Software Development

Docker has become a vital tool in modern software development. It allows developers to package applications with all their dependencies into lightweight, portable containers. Whether you're building web applications, APIs, or microservices, Docker can simplify development, testing, and deployment.

What is Docker?

Docker is an open-source platform that enables you to build, ship, and run applications inside containers. Containers are isolated environments that contain everything your app needs—code, libraries, configuration files, and more—ensuring consistent behavior across development and production.

Why Use Docker?

Consistency: Run your app the same way in every environment.

Isolation: Avoid dependency conflicts between projects.

Portability: Docker containers work on any system that supports Docker.

Scalability: Easily scale containerized apps using orchestration tools like Kubernetes.

Faster Development: Spin up and tear down environments quickly.

Basic Docker Concepts

Image: A snapshot of a container. Think of it like a blueprint.

Container: A running instance of an image.

Dockerfile: A text file with instructions to build an image.

Volume: A persistent data storage system for containers.

Docker Hub: A cloud-based registry for storing and sharing Docker images.

Example: Dockerizing a Simple Python App

Let’s say you have a Python app called app.py: # app.py print("Hello from Docker!")

Create a Dockerfile: # Dockerfile FROM python:3.10-slim COPY app.py . CMD ["python", "app.py"]

Then build and run your Docker container: docker build -t hello-docker . docker run hello-docker

This will print Hello from Docker! in your terminal.

Popular Use Cases

Running databases (MySQL, PostgreSQL, MongoDB)

Hosting development environments

CI/CD pipelines

Deploying microservices

Local testing for APIs and apps

Essential Docker Commands

docker build -t <name> . — Build an image from a Dockerfile

docker run <image> — Run a container from an image

docker ps — List running containers

docker stop <container_id> — Stop a running container

docker exec -it <container_id> bash — Access the container shell

Docker Compose

Docker Compose allows you to run multi-container apps easily. Define all your services in a single docker-compose.yml file and launch them with one command: version: '3' services: web: build: . ports: - "5000:5000" db: image: postgres

Start everything with:docker-compose up

Best Practices

Use lightweight base images (e.g., Alpine)

Keep your Dockerfiles clean and minimal

Ignore unnecessary files with .dockerignore

Use multi-stage builds for smaller images

Regularly clean up unused images and containers

Conclusion

Docker empowers developers to work smarter, not harder. It eliminates "it works on my machine" problems and simplifies the development lifecycle. Once you start using Docker, you'll wonder how you ever lived without it!

A Comprehensive Guide to MongoDB Server: The Database for Modern Applications

MongoDB is a popular NoSQL database known for its flexibility, scalability, and performance in handling large-scale data. As a document-oriented database, MongoDB stores data in flexible, JSON-like documents, making it well-suited for applications that need to manage diverse data types and structures. MongoDB servers are widely used across industries, powering everything from content management systems to real-time analytics and IoT applications.

This article will explore what MongoDB is, its core features, installation process, and best practices for managing a MongoDB server.

What is MongoDB?

MongoDB is an open-source, NoSQL database that diverges from traditional relational databases like MySQL or PostgreSQL. Instead of storing data in rows and columns, MongoDB uses collections and documents, offering a more flexible and dynamic schema that adapts easily to changing application needs.

Core Concepts in MongoDB:

Database: A container for collections.

Collection: A group of MongoDB documents, similar to a table in a relational database.

Document: The basic unit of data in MongoDB, represented in a JSON-like format.

Key Features of MongoDB Server

Schema Flexibility MongoDB allows for a dynamic schema, enabling each document in a collection to have a different structure. This is ideal for applications where data requirements may evolve over time.

Horizontal Scalability MongoDB supports sharding, allowing the distribution of data across multiple servers, which helps manage large datasets and maintain high availability. Sharding makes MongoDB an excellent choice for applications that need to handle large volumes of data across multiple geographic locations.

High Performance MongoDB is optimized for read and write operations, delivering faster performance, particularly for applications that require rapid data ingestion and real-time analytics.

Integrated Aggregation Framework The aggregation framework in MongoDB allows for powerful data transformations and analysis directly within the database, helping developers generate complex reports without relying on external tools.

Built-in Replication MongoDB’s replica sets allow automatic failover and data redundancy, providing high availability and protection against hardware failures.

Installing MongoDB Server

MongoDB is compatible with multiple platforms, including Linux, Windows, and macOS. Here’s a general guide to installing MongoDB Community Server on each of these systems.

1. Installing MongoDB on Linux

MongoDB provides repositories for several Linux distributions.

bash

Copy code

# For Ubuntu/Debian systems:

wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list

sudo apt update

sudo apt install -y mongodb-org

To start MongoDB on Ubuntu/Debian:

bash

Copy code

sudo systemctl start mongod

sudo systemctl enable mongod  # to start on boot

2. Installing MongoDB on Windows

Download the MongoDB Community Server MSI installer from the MongoDB website.

Run the installer and select “Complete” setup.

Add MongoDB to the system PATH during installation for easy command-line access.

To start MongoDB on Windows, navigate to the installation folder and run:

cmd

Copy code

mongod.exe --dbpath="C:\path\to\your\data\db"

3. Installing MongoDB on macOS

On macOS, MongoDB can be installed via Homebrew:

bash

Copy code

brew tap mongodb/brew

brew install mongodb-community@5.0

brew services start mongodb/brew/mongodb-community

Once installed, MongoDB runs as a background service, and you can start, stop, or restart it using brew services.

Basic Commands for MongoDB Server Management

Starting MongoDB Shell Use mongo to enter the MongoDB shell and interact with databases.

bash

Copy code

mongo

Creating a Database and Collection To create a new database, use the use command:

javascript

Copy code

use myDatabase

Then, create a collection by inserting a document:

javascript

Copy code

db.myCollection.insert({ name: "Alice", age: 30 })

Inserting Documents Documents can be inserted using the insertOne or insertMany methods.

javascript

Copy code

db.myCollection.insertOne({ name: "Bob", age: 25 })

db.myCollection.insertMany([{ name: "Charlie", age: 35 }, { name: "Diana", age: 28 }])

Querying Data Query documents with find:

javascript

Copy code

db.myCollection.find({ age: { $gte: 30 } })

Updating Documents Use updateOne or updateMany to modify existing documents:

javascript

Copy code

db.myCollection.updateOne({ name: "Alice" }, { $set: { age: 31 } })

Deleting Documents Delete documents with deleteOne or deleteMany:

javascript

Copy code

db.myCollection.deleteOne({ name: "Bob" })

Best Practices for MongoDB Server Management

Optimize Data Schema Design Design your schema based on query patterns and application requirements. Avoid deeply nested documents if they lead to complex queries and ensure indexes are created for frequently queried fields.

Utilize Indexing Indexes improve query performance by enabling MongoDB to retrieve data faster. However, over-indexing can slow down write operations, so choose indexes strategically.

Monitor Performance Use MongoDB's built-in mongostat and mongotop tools to monitor database performance and address issues proactively. Cloud-based solutions like MongoDB Atlas provide more comprehensive monitoring.

Implement Replication and Backups Regularly back up your data and use MongoDB’s replication features to ensure data availability. Setting up replica sets enables automatic failover in case of server failure.

Use Sharding for Horizontal Scaling For large datasets, implement sharding to distribute data across multiple nodes. MongoDB will manage data distribution and load balancing automatically.

Google Regional Persistent Disk: VMs Multi-Zone Storage

Google Regional Persistent Disk

Are you seeking for a natively Google Compute Engine solution that offers 0% RPO, is production-ready, and provides high availability for your mission-critical workloads? You only need to look at Google Regional Persistent Disk. This blog post from Google Cloud explores how you can provide resilience, ease of management, and continuous protection for your most critical and demanding applications by utilizing Regional PD’s cross-zone synchronous replication capabilities.

Regional Persistent Disks Regional PD: A mission well suited for it-important tasks Workloads that are crucial to the daily operations of every modern firm are mission-critical. These are the systems that the company needs to function, thus any interruption to their workloads could have a big effect on the company.

Because of this, companies require highly available infrastructure, which includes highly available storage capable of:

Replicate data seamlessly while maximising performance for certain kinds of tasks. Be extremely robust against a variety of problems that could impact availability. Be really easy to assemble and operate For many of the mission-critical high availability storage requirements of Google Cloud customers, Regional PD is a strong fit and meets all of these criteria.

Incredibly effective for your workloads that are mission-critical Google Cloud customers use Regional PD for MySQL, Postgres, SQL Server, Jupyterlab, Kafka, Druid, Redis, Solr, EventStoreDB, Elasticsearch, MongoDB, and other workloads due to its write and read performance of 1000MB/s and 80K IOPS per volume, respectively.

Extremely reliable and resilient to failure With regional PD, synchronous replication between zones is continuous and has an RPO of zero in the event that one zone goes down. Regional PD prioritizes availability and automatically reroutes I/O to the last available storage replica in the event of a zonal outage. Regional PD self-heals and brings the unavailable replica back online to continue RPO=0 replication later, once the unavailable zone has recovered. To ensure workload availability, a virtual machine (VM) can be tied to the regional PD if it needs to be recovered in the second zone.

For your mission-critical applications, full replication means that all the data required to maintain the high availability of your compute instance is replicated. This includes not just data disc replication but also boot disc replication for virtual machine instances. When Virtual Machines (VMs) employ Regional PD as its boot disc, users are shielded against potential storage problems that could prevent the VM from booting and from data loss from VMs that rely on the boot disc for data, such as Windows VMs.

Easy to set up and maintain Configuring Regional PD for mission-critical workloads is really simple. It only takes a few minutes to add a new Regional PD disc whether starting a new virtual machine or updating an existing one. Using the Google Cloud console, gcloud, Terraform, and REST APIs, you can add Regional PDs. Once configured, your workload can start serving reads and writes to the Google Regional Persistent Disk in the same way as it would with any other block storage, with the exception that all writes will automatically use synchronization replication to replicate to another replica on a secondary zone.

High Availability Regional PD in Google Cloud services with high availability A number of Google Cloud services, including as GKE Stateful High Availability (HA) Controller, Cloud SQL HA configuration, and Cloud Shell, leverage Regional PD in addition to Compute Engine workload deployments.

The completely managed database service offered by Google Cloud for MySQL, PostgreSQL, and SQL Server is called Google Cloud SQL. When enabled, as soon as a Cloud SQL database instance is created, the configuration immediately configures it to use Regional PD as the primary storage and replicates writes to a secondary zone. When necessary, failover is a straightforward one-step command that switches all networking, compute, and client applications to the secondary zone’s alternate instance.

The terminal window on Google Cloud called Cloud Shell gives you command line access to virtual machines (VMs) in your projects. Users get 5GB of Regional PD disk storage for their terminal’s home directory with each Cloud Shell terminal session. In the event that there are issues with the zone housing the home directory storage, this helps guarantee that the home directory is highly available. The Cloud Shell service automatically uses the extra Regional PD replica in the event of a zonal issue, ensuring uninterrupted access to home directory data.

Final reflections This blog post from Google Cloud explains how Google Regional Persistent Disk was designed with the goal of maximizing availability for your mission-critical workloads in Google Cloud while also delivering ease in management, performance, and resilience. Furthermore, Google Cloud talked about how users have implemented Regional PD in expansive production settings and how it offers storage availability across a number of core Google Cloud services.

Concerning the local persistent disk You can use Compute Engine’s Regional Persistent Disk storage option to create high availability (HA) services. Google Regional Persistent Disk provides high availability (HA) for disk data for up to one zonal failure by synchronously replicating data between two zones within the same region.

Workloads with a reduced Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are intended for use with Regional Persistent Disk volumes.

Replication of zones on discs for local persistent discs Regional Persistent Disk volumes hold disc data in primary and secondary zones. For disc attachment, the primary zone is the same as the VM instance. A secondary zone is a different area inside the same region of your choice. In each of these zones, Compute Engine keeps copies of your local persistent disk volume. To guarantee HA, Compute Engine synchronously duplicates data you write to your disc to the disc replicas in both zones. To ensure longevity, the data of each zonal replica is distributed among several physical machines in the zone. Zone replicas guard against brief disruptions in one of the disk zones and guarantee that the Persistent Disk volume’s data is always accessible.
