Navigating the Open Source: My Second Hactoberfest Contribution to turbo-nextui-starter
Tags: hacktoberfest, hacktoberfest23, beginners, github
Published: 2023-11-21 08:21:03

During my search for the second repository to contribute to, I stumbled upon godkingjay's [turbo-nextui-starter](https://github.com/godkingjay/turbo-nextui-starter) repository. Interestingly, there was no CONTRIBUTING.md file in this repository. This motivated me to work on this repository. This blog post documents my specific contribution to the project, focusing on the creation of the CONTRIBUTING.md file.

## Issue Identification
The issue I tackled was succinctly described in [Issue #1](https://github.com/godkingjay/turbo-nextui-starter/issues/1), which called for the addition of a CONTRIBUTING.md file. This file plays a crucial role in guiding potential contributors on how to engage with the project, making the contribution process more accessible and streamlined.

## What i have learned to fix this issue?
To address this issue effectively, I needed to familiarize myself with the project's contribution guidelines and understand the expectations set by the maintainers. Learning how to structure a meaningful CONTRIBUTING.md file required research into best practices for open-source projects and understanding the specific needs of turbo-nextui-starter.

## Crafting Solution

To resolve the issue, I generated a [CONTRIBUTING.md](https://github.com/godkingjay/turbo-nextui-starter/blob/master/CONTRIBUTING.md) file. This file serves as an extensive guide for contributors, divided into two primary sections: "I Have a Question" and "I Want to Contribute." The former offers guidelines for asking questions, urging users to search for existing issues before creating new ones. The latter provides clear, step-by-step instructions to guide potential contributors through the forking and pull request process.

## Reflection on the contribution
Working on this issue was a valuable experience. It wasn't just about coding but also about creating a welcoming environment for collaboration. Crafting the CONTRIBUTING.md file required thoughtful consideration of the diverse ways people interact with the project, from asking questions to submitting code changes. The templates I added aim to streamline these interactions, making it easier for both contributors and maintainers.

This is my [Pull Request.](https://github.com/godkingjay/turbo-nextui-starter/pull/3)
Reversing sort order in Rust
Tags: rust, sorting, sources, algorithms
Published: 2023-11-21 08:19:13

Rust allows sort items by key easily with `.sort_by_key`, here is example, it will put important notes to the end:

```rust
#[derive(Debug)]
struct Note {
    important: bool,
    title: &'static str,
}
let mut notes = vec![
    Note { important: false, title: "ddd"},
    Note { important: true, title: "aaa"},
    Note { important: false, title: "ccc"},
];
notes.sort_by_key(|k| k.important);
println!("{:?}", notes);
```

But reversing order of sorting with key may be not so obvious, it is achieved with `Reverse` helper struct, here is how it can be applied to above example, in order to put important notes first:

```rust
use std::cmp::Reverse;
// ...
notes.sort_by_key(|k| Reverse(k.important));
println!("{:?}", notes);
```

How is it implemented? Let's look at the source code of Rust standard library:

```rust
pub struct Reverse<T>(pub T);

impl<T: Ord> Ord for Reverse<T> {
    fn cmp(&self, other: &Reverse<T>) -> Ordering {
        other.0.cmp(&self.0)
    }
}
```

The implementation is straightforward, it is [newtype](https://doc.rust-lang.org/rust-by-example/generics/new_types.html) wrapper for original type, and for types with `Ord` trait it reimplements `Ord` but instead of comparing `self` with `other` it comparing `other` with `self` meaning it will reverse order in the result. Simple and beautiful!

And it will play nicely with complex keys too, lets put important notes first, and sort by title ascending for same importance groups:

```rust
notes.sort_by_key(|k| (Reverse(k.important), k.title));
println!("{:?}", notes);
```

Of course in some cases it is possible to just negate value, like in this example using `!k.important` will produce same results, but negating is not always possible (eg. strings). Regarding performance I've benchmarked both methods and have not found any difference, both methods require same time if ordering booleans.

Console Magic: 10 Unexplored JavaScript Console Techniques
Tags: javascript, typescript, tutorial, webdev
Published: 2023-11-21 08:13:34

Debugging and monitoring JavaScript code is a fundamental part of a developer's workflow. The `console` object in JavaScript provides a range of methods that assist in debugging, logging, and monitoring application data. Let's explore some of the most commonly used `console` methods and their practical examples:

### 1. `console.log()`

The ubiquitous `console.log()` method is used to log messages to the console.

Example:
```javascript
const message = 'Hello, Console!';
console.log(message);
```

### 2. `console.error()`

Used to log error messages to the console with a red icon indicating an error.

Example:
```javascript
const errorMessage = 'Something went wrong!';
console.error(errorMessage);
```

### 3. `console.warn()`

Logs a warning message to the console with a yellow icon indicating a warning.

Example:
```javascript
const warningMessage = 'Proceed with caution!';
console.warn(warningMessage);
```

### 4. `console.info()`

Logs informational messages to the console with a blue-colored 'i' icon indicating information.

Example:
```javascript
const infoMessage = 'This is an informative message.';
console.info(infoMessage);
```

### 5. `console.table()`

Displays tabular data in a table format.

Example:
```javascript
const users = [
  { id: 1, name: 'Alice', age: 30 },
  { id: 2, name: 'Bob', age: 25 },
  { id: 3, name: 'Charlie', age: 35 }
];
console.table(users);
```

### 6. `console.group()`, `console.groupCollapsed()`, `console.groupEnd()`

Used to group log messages in a collapsible group in the console for better organization.

Example:
```javascript
console.group('Group 1');
console.log('Message 1');
console.log('Message 2');
console.groupEnd();

console.groupCollapsed('Group 2');
console.log('Message 3');
console.log('Message 4');
console.groupEnd();
```

### 7. `console.assert()`

Logs a message and stack trace to the console if an assertion is false.

Example:
```javascript
const condition = false;
console.assert(condition, 'The condition is false!');
```

### 8. `console.count()`

Logs the number of times this particular console count is called.

Example:
```javascript
for (let i = 0; i < 5; i++) {
  console.count('Iteration');
}
```

### 9. `console.time()`, `console.timeEnd()`

Measure the time taken by a specific code block using `console.time()` and `console.timeEnd()`.

Example:
```javascript
console.time('Timer');
// Code block to measure time
console.timeEnd('Timer');
```

### 10. `console.clear()`

Clears the console.

Example:
```javascript
console.clear();
```

The `console` object in JavaScript provides a powerful set of tools for debugging and monitoring your code. Experimenting with these methods and incorporating them into your development workflow can significantly enhance your ability to diagnose and fix issues within your applications.

Sort arrays of zero's, one's and two's
Tags: programming, beginners, sort, logic
Published: 2023-11-21 08:03:30

This is a basic problem within understanding of array as a data structure and operations of sort as an algorithm upon the data structure.

Here we will start with the basics and crawl our way up with  finding multiple constraints, hurdles or bottlenecks within our algorithm.


## Approach 1
> Simple sort

One obvious way is to use the known sorting techniques as section sort, or merge sort or quick sort.

The code goes here [Simple Sorting Solution](https://gist.github.com/OBrutus/0de637dc1ae2e46e8a9eb0dab6fdbf5a) Or shown below

   

Simplest, but, no one want's it. As in such case we have making no use of the fact that we are having only 3 elements ie, 0, 1, and 2. Instade, we treated every number as a plain integer and sort it.


## Approach 2
> Hasing Solution

This one is slightly better, here we are taking into account how many times we have encountered, 0's 1's and 2's. Once that is known. By basic number system, we know all 0's occur before 1's and all 1's before 2's. In such a way, we fill up the array, as per the number of 0's then 1's and then 2's.

The code goes here [Hashing Solution](https://gist.github.com/OBrutus/0de637dc1ae2e46e8a9eb0dab6fdbf5a#file-approach2-java) Or shown below    

This too, have few problems
1. What if the count which we are taking into consideration is out of bound from the integer limit. One can argue that in such cases we can take long value into consideration but still the limit hit's then? BigInteger? But this does not solve our problem. This in fact slows the system and makes it more prone to errors as the size of the array increases.


2. What if the input is not a static data but a stream of data. In such cases, the input values will continue to come and not stop. In such case, our algorithm would halt upon the counting of 0's 1's and 2's step only, and not move forward. Hence, not making the in place streaming content sorted.


## Approach 3
> Poniters and Insertion

Upon seeing above hurdles, we come to know that the approach can be improved and adapted to new circumstances.

Here we can have the insertion point's within the array. These points will indicate where the incoming data could be inserted, for 0's 1's and 2's. For any such new upcoming streaming data, we need to look for the apt pointer within the 0, 1, and 2, then insert the upcoming data.

The code goes here [Pointer and Insertion Solution](https://gist.github.com/OBrutus/0de637dc1ae2e46e8a9eb0dab6fdbf5a#file-approach3-java) Or shown below

In such a way we have, removed the hurdles from the approach for now.
This still seems to have a minor issue within scalability, like what if we have 0 1 2 and 3 within the digits.
In such cases we need to have multiple pointers for insertion and handling would be complex although if that would take place then the problem itself would be changed and would not be ***Sort Arrays of Zero's One's and Two's***

Bun: The Supercharged JavaScript Runtime
Tags: bunjs, javascript, runtime, development
Published: 2023-11-21 08:00:00

Bun is an intriguing new addition to the JavaScript ecosystem, designed as a runtime like Node.js but with a focus on high performance. Let's dive deep into its workings, architecture, and capabilities.

## How Bun Works

### Zig-Based Architecture
Unlike Node.js, which is built on C++, Bun is primarily written in Zig, a language known for its performance and safety features. Zig provides Bun with low-level control and efficient memory management, contributing to its high-speed operations.
### JavaScript Engine
Bun integrates a high-performance JavaScript engine that is JIT (Just-In-Time) compiled. This engine is crucial for executing JavaScript code swiftly and efficiently.
### Compatibility with Node.js and Web APIs
Bun aims for compatibility with Node.js and web APIs. This means that it can run most Node.js packages and JavaScript written for web browsers, facilitating easier migration and interoperability.

## How is it built
As mentioned before, the core of Bun is built using Zig's powerful features like compile-time code generation and cross-compilation. These features help in optimizing the runtime for different platforms and use cases.

Bun integrates with existing technologies such as libuv (for asynchronous I/O) and other C libraries, blending the best of both worlds for performance and functionality.

Throughout its architecture, Bun emphasizes performance optimizations. This includes faster startup times, efficient bundling, and quicker execution of JavaScript code.

## Key features

### Fast Package Manager
Bun comes with a built-in package manager that is touted to be significantly faster than npm or Yarn. It leverages parallel downloading and caching for efficiency.

### Bundling and Transpiling
Bun includes capabilities for bundling and transpiling JavaScript and TypeScript code. Its bundler is integrated into the runtime, offering speed advantages over traditional JavaScript tooling.

### Native TypeScript Support
Unlike Node.js, which requires external tools for TypeScript support, Bun natively understands TypeScript. This eliminates the need for additional transpilation steps.

### Web APIs and Polyfills
Bun supports various Web APIs and provides polyfills for Node.js-specific features, making it easier to run web code on the server side.

### Fast HTTP Server
Bun's HTTP server is designed for high performance, capable of handling a large number of concurrent connections with low latency.

### Cross-Platform Support
Bun is designed to work across different platforms, with support for Linux, macOS, and Windows.

---

Bun is still evolving, with an active community contributing to its development. Its focus on performance and efficiency positions it as a compelling alternative in scenarios where speed and resource optimization are critical. As it matures, Bun may well become a significant player in the JavaScript runtime space, alongside Node.js and Deno.
Kubernetes Troubleshooting
Tags: troubleshooting, monitoring, logging, kubernetes
Published: 2023-11-21 08:00:00

With Kubernetes large and diverse workloads can be handled.
To keep track of all these processes, monitoring is essential.

## Monitoring
To monitor the application you need to collect metrics, like CPU, memory, disk usage and bandwidth on your nodes.

Because Kubernetes is a distributed system, it needs to be monitored and trace cluster-wide. 

You can use exterior tools like **Prometheus** and visualize it with **Grafana**. But to get started I recommend you to use the **Kubernetes dashboard**, as it is very easy to set up and you have a default user interface with the most important metrics.

## Logging
If you have aggregated logs, you can visualize issues and search the logs for issues. 

In Kubernetes the kubelet writes container logs to local files. With the command `kubectl logs` you can see this logs.

If you want to perform cluster wide logging, you can use **Fluentd** to aggregate logs.
Fluentd agents run on each node via a DeamonSet and feed them to an ElasticSearch instance prior to visualization.

## Troubleshooting
### Errors in the container
If you are not sure where to start, run

`kubectl describe your-pod`

This will report 
- the overall status of the pod: running, pending or an error state
- the container configuration
- the container events

If the pod is already running you can first look at the standard outs of the container. One common issue is that there are not enough resources allocated.

`kubectl logs your-pod your-container`

You can look for error messages in the logs.

If there are errors inside a container you execute into the shell of the container to see what is going on.

`kubectl exec -it yourdeployment -- /bin/sh`


### Networking issues
This could be the next place, where the issues arise.
So you can go ahead and check the DNS, firewalls and general connectivity.

### Security issues
You might want to check your RBAC.
SELinux and AppArmor are also common issues, especially with network-centric applications.

If you don't know where to start, you can disable security for testing, to delimit the issue source. But be sure to reenable security afterwards.

Another reason - not only for security issues - could be an update. You can roll back to find out when the issue was introduced.

Hi from 2 months later! I finally got around to wrapping this project up, which is a clone of a simplified Wikipedia. I had loads of fun designing the baby blue-themed UI from scratch and implementing it using Django. Django was introduced in week 3's lecture and it wasn't nearly enough to make me feel comfortable building this project, which I did what I could with Googling.



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/m850ipg1j0nj6c9zsgc4.gif)


There were 7 main features of this website, my favorites included creating/editing a page, randomly displaying a page, and the search functionality. I struggled the most with the search feature to make it work just right because you also had to account for if a user just typed in a substring of the actual entry page name and showed them the search results regardless of the spelling typo. 

The overall features of this project reminded me of the structure you would have for a blog, which includes the usual CRUD (create, read, update, delete), except this project's criteria didn't need to have the delete function. 

Overall, this project was a good challenge as it took over 15 hours (roughly) for me to complete!

Here's a [demo](https://youtu.be/wnOig0RRhDs?si=X0k-jBY3G2nWNmay) of the finished project with timestamps.
