Firefox: change the active tab color
Tags: firefox
Published: 2024-02-22 11:05:13

On the Firefox browser, especially with some themes, the active (ie. currently selected) tab can be difficult to distinguish, because it may have a similar background colour as the other tabs.

One simple and direct solution is to modify the "userChrome.css" file manually, through the following steps.

(Some Firefox and CSS knowledge is assumed.)

1. On Firefox, go to the "about:config" page (by typing "about:config" in the url box), enter "toolkit.legacyUserProfileCustomizations.stylesheets" in the searchbox, and set the value to "true".

2. Again on Firefox, go to the "about:support" page, look for "Profile Folder", then open this folder.

3. Inside this folder, look for (or create) a "chrome" folder, and inside the "chrome" folder, look for (or create) a "userChrome.css" file.

4. Inside the "userChrome.css" file, carefully add the following 3 lines at the top level (crimson or your favourite colour) :
```css
.tabbrowser-tab[selected="true"] .tab-background {
  background: crimson none !important;
}
```
<ol start="5">
  <li>Restart Firefox.</li>
</ol>
Participating in The Collab Lab: Week #3
Tags: webdev, frontend, collablab
Published: 2024-02-22 11:02:57

This is week number 3 for my Collab Lab project. 
Since week 1, I have been contributing by adding different features to our app. I've had the opportunity to pair with all the developers in the team on these issues.

Last Sunday, we had our first team retrospective, so I am sharing here some personal thoughts after spending some time reflecting on the job done so far.

✨ One of my goals when joining The Collab Lab was to refresh and deepen my React knowledge, so I am glad I am making progress in that sense. Also, I was missing the collaborative part of the development process, so I am really enjoying the teamwork.

💪🏽 I am also learning a lot from the collaboration process and feel quite confident using GitHub. The team is communicating very well, and the project is well on track.

🚧 I am always looking forward to improving my communication skills and becoming more confident when presenting my work at the demos.

---

## Learning highlights of my week
My learnings have been focusing on React, this week I continued my [React's blog post series](https://dev.to/vivitt/series/26502) with the useMemo hook that was new for me and is a solution to improve app performance by avoiding unnecessary calculations, especially when working with slow methods or large amounts of data.

See you next week! Thanks for reading :)

What is (LVM) Logical Volume Manager?
Published: 2024-02-22 11:00:53

The Logical Volume Manager (LVM) is a technology used in Unix-like operating systems, including Linux, to manage disk drives and storage volumes in a more flexible and dynamic manner. It provides a layer of abstraction between physical storage devices (such as hard drives, SSDs, or RAID arrays) and the operating system's file systems.

Here are some key aspects of Logical Volume Manager (LVM):

1. **Logical Volumes**: LVM allows you to create logical volumes, which are virtual partitions that can span across one or more physical storage devices. These logical volumes behave like regular disk partitions but offer more flexibility in terms of size management and resizing.

2. **Volume Groups**: LVM organizes physical volumes into volume groups. A volume group is a pool of storage made up of one or more physical volumes. Logical volumes are created within volume groups.

3. **Physical Volumes**: Physical volumes are actual storage devices, such as hard drives or SSDs, that are initialized for use with LVM. These physical volumes can be combined into volume groups.

4. **Striping and Mirroring**: LVM supports data striping (RAID 0) and mirroring (RAID 1) across multiple physical volumes for improved performance and data redundancy.

5. **Dynamic Resizing**: One of the key features of LVM is its ability to dynamically resize logical volumes and volume groups while the file systems they contain are mounted and in use. This allows for more flexible management of storage space without the need to unmount file systems or perform complex partition resizing operations.

6. **Snapshots**: LVM supports creating snapshots, which are read-only copies of a logical volume at a particular point in time. Snapshots can be useful for data backup, testing, or system rollback purposes.

Overall, LVM provides administrators with greater flexibility and control over storage management, making it easier to manage large-scale storage configurations, handle storage growth, and improve system reliability and performance.
Queue Data Structure Detailed Examples
Tags: queue, algorithms, datastructures, programming
Published: 2024-02-22 11:00:03

## Queue Data Structure
A queue is a fundamental data structure in computer science that follows the First-In-First-Out (FIFO) principle. The element that enters the queue first is the first to be removed and the element enters last is the last to be removed.

## Operations in Queue
- [Enqueue Operation](https://devsenv.com/tutorials/queue#content-operations-in-queue)
- [Dequeue Operation](https://devsenv.com/tutorials/queue#content-operations-in-queue)
- [Peek (or Front) Operation](https://devsenv.com/tutorials/queue#content-operations-in-queue)
- [Size Operation](https://devsenv.com/tutorials/queue#content-5-search-operation)
- [Search Operation](https://devsenv.com/tutorials/queue#content-5-search-operation)

## Practical Queue Example in C Programming

```c
#include <stdio.h>

#define MAX_SIZE 100

struct Queue {
    int arr[MAX_SIZE];
    int front, rear;
};

// Function to initialize the queue
void initQueue(struct Queue* q) {
    q->front = q->rear = -1;
}

// Enqueue Operation
void enqueue(struct Queue* q, int item) {
    if (q->rear == MAX_SIZE - 1) {
        printf("Queue Overflow: Cannot enqueue more elements.\n");
        return;
    }

    if (q->front == -1) {
        q->front = q->rear = 0;
    } else {
        q->rear++;
    }

    q->arr[q->rear] = item;
    printf("%d enqueued to the queue.\n", item);
}

// Dequeue Operation
void dequeue(struct Queue* q) {
    if (q->front == -1) {
        printf("Queue Underflow: Cannot dequeue from an empty queue.\n");
        return;
    }

    int dequeuedItem = q->arr[q->front];

    if (q->front == q->rear) {
        q->front = q->rear = -1; // Reset the queue when the last element is dequeued
    } else {
        q->front++;
    }

    printf("%d dequeued from the queue.\n", dequeuedItem);
}

// Peek (or Front) Operation
void peek(struct Queue* q) {
    if (q->front == -1) {
        printf("Queue is empty.\n");
    } else {
        printf("Front element: %d\n", q->arr[q->front]);
    }
}

// Size Operation
int size(struct Queue* q) {
    if (q->front == -1) {
        return 0;
    }
    return q->rear - q->front + 1;
}

// Search Operation
int search(struct Queue* q, int item) {
    for (int i = q->front; i <= q->rear; i++) {
        if (q->arr[i] == item) {
            printf("%d found in the queue.\n", item);
            return 1;
        }
    }
    printf("%d not found in the queue.\n", item);
    return 0;
}

// Check if the queue is empty
int isEmpty(struct Queue* q) {
    return q->front == -1;
}

int main() {
    struct Queue myQueue;
    initQueue(&myQueue);

    enqueue(&myQueue, 10);
    enqueue(&myQueue, 20);
    enqueue(&myQueue, 30);

    peek(&myQueue);

    dequeue(&myQueue);
    peek(&myQueue);

    printf("Queue Size: %d\n", size(&myQueue));

    search(&myQueue, 20);
    search(&myQueue, 40);

    return 0;
}
```

Dev/prod parity - The Twelve Factor App Methodology
Tags: beginners, tutorial, cloud, architecture
Published: 2024-02-22 11:00:00

Welcome back to our exploration of the Twelve Factors in Software Development. In this segment, we'll delve into Factor 10: Dev/Prod Parity. This factor underscores the importance of maintaining similarity between development and production environments for a smoother development and deployment process.

## Dev/Prod Parity: Keep Development and Production as Similar as Possible
The Dev/Prod Parity factor advocates for minimizing the discrepancies between your development and production environments. This includes not only the infrastructure and dependencies but also the processes and workflows. Ensuring a high degree of parity helps uncover issues early in the development lifecycle and facilitates a more reliable deployment to production.

## Why It Matters
Discrepancies between development and production environments can lead to a variety of issues, such as differences in behavior, unanticipated bugs, and deployment challenges. By maintaining parity, you reduce the risk of encountering surprises during deployment and ensure a smoother transition from development to production.

## How to Implement
Utilize tools and practices that enable consistency between environments. This may involve using containerization technologies like Docker to package applications and their dependencies, using configuration management tools to maintain consistent server configurations, and adopting infrastructure-as-code practices to define and version infrastructure.

## Example in Action
Consider a web application that uses a specific version of a database in production. To maintain Dev/Prod Parity, use Docker to create a container image that includes both the application and the exact database version. This ensures that developers work with an environment that closely resembles the production setup.

```bash
# Dockerfile for maintaining Dev/Prod Parity
FROM node:14

# Copy application files
COPY . /app

# Set the working directory
WORKDIR /app

# Install dependencies
RUN npm install

# Expose the application port
EXPOSE 3000

# Start the application
CMD ["npm", "start"]
```

As you can see, in the above example there are no differences between environments. It is, of course, a tremendously simplified example.

By adhering to the Dev/Prod Parity factor, you reduce the risk of encountering "it works on my machine" issues and enhance the reliability of your deployment process.

Stay tuned for Factor 11: Logs, where we'll explore the significance of treating logs as event streams and how it contributes to effective debugging and troubleshooting.
Understanding how docker works
Tags: docker, webdev, programming, beginners
Published: 2024-02-22 10:49:15

Imagine you have a bakery (your development environment) where you bake various cakes and pastries (different applications).Traditionally, each cake recipe requires its own set of utensils, ingredients, and oven settings, making it difficult to manage and switch between creations.

Docker acts like a modular baking system. Instead of having dedicated equipment for each cake, you can now:

* Prepare pre-packaged "ingredient kits" (Docker images).Each kit contains the specific software tools, libraries, and configurations needed for a particular type of cake (application). You can find pre-made kits for common cakes in a "shared pantry" (Docker Hub) or create your own custom kits.

* Use standardized "ovens" (containers). These ovens are isolated environments that run the "ingredient kit" (image) you choose. Every oven acts independently, ensuring your cakes (applications) don't interfere with each other, even if you bake multiple types at once.

* Switch between ovens and recipes easily. Need to bake a different cake? Simply choose a new kit and "pop it" into a different oven. This makes it easy to test, deploy, and manage various applications without worrying about environment conflicts.

So, the different kitchens and ovens represent various environments where you run your applications (e.g., development machines, production servers), and each application can be a different cake in your bakery, benefiting from the modularity and consistency Docker provides.
