In the preceding text, we delved into the installation of MoviePy and utilized the VideoFileClip class to access video files, performing simple edits like resizing, rotation, and segment clipping.

This article's focus lies on understanding MoviePy's audio capabilities.

## Creating AudioClip

MoviePy offers two methods to create audio clips: extracting audio from video files and generating audio clips based on existing audio files.

### Extracting Audio from Video Files

Assuming we possess a video file named `input_video.mp4`, we can directly extract its audio with the following code:

```python
from moviepy.editor import *

video = VideoFileClip("input_video.mp4")
audio = video.audio
audio.write_audiofile("output_audio.mp3")
```

### Generating Audio Clips from Audio Files

By using AudioFileClip, we can read the audio file extracted from the video. The code appears as follows:

```python
audio = AudioFileClip("output_audio.mp3")
```

We can embed this audio clip into another video segment.

Directly create a video using TextClip and set the video duration using audio.duration.

```python
video = TextClip("Hello MoviePy", color="orange", size=(100, 100))
video = video.set_duration(audio.duration).set_fps(1)
```

Let's load the audio onto this video.

Here's the code:

```python
video.audio = audio
video.write_audio("text_video.mp4")
```

When opening the video file using QuickTime Player on a Mac, remember to add the parameter audio_codec="aac" when writing:

```python
video.write_audio("text_video.mp4", audio_codec="aac")
```

Upon completion, you can open the video and review the effects.

## Audio Operations

This section discusses fundamental operations on AudioClips, including volume control, audio segment clipping, and removing audio from videos.

### Volume Control

Adjusting the volume of audio clips is accomplished directly through the `volumex` method of `AudioClip`.

To decrease the volume by 50%, use the code below:

```python
audio = audio.volumex(0.5)
```

### Segment Clipping

Similar to trimming videos, subclip enables us to extract specific portions of audio clips.

For instance, to extract the audio segment from 5 to 15 seconds, use the code:

```python
audio = audio.subclip(5, 15)
```

### Removing Audio from Videos

Here's a handy trick: to remove audio from a video, set the `audio` parameter to `False` when reading the video file with VideoFileClip.

```python
video = VideoFileClip("input_video", audio=False)
```

Alternatively, you can utilize the `without_audio` method of VideoFileClip to remove audio from video segments.

```python
video = video.without_audio()
```

Isn't it simple?

The fuss with CRLF and LF in Git 😕
Tags: webdev, github, git, beginners
Published: 2024-01-04 14:08:24

This problem arises with Git when team members are using different operating systems, e.g., Windows vs Mac/Linux.

A non-AI-generated summary of the solution:

**Step 1.** Decide whether to save changes in the Git index (the Git commit database) in CRLF or LF. Git wants to save in LF. The world wants to save in LF. Linux and Mac have the default of LF. Windows is alone in having CRLF. So the decision is made: LF.

**Step 2.** In git-config, `core.autocrlf=input` means when generating files from Git index for the user, Git will do CRLF for Windows and LF for Mac/Unix. Also, while writing to Git index from files, it will use LF. Having `core.autocrlf=false` means Git won't do anything. Just save stuff as is. So, make sure you don't change the default setting.

Another case to be aware of is that code formatters like Prettier may format the code and save the file with LF as line-endings in Windows, although the file had CRLF. In this case, Git will notice it and show a warning. Safely ignore this warning, not important at all, forget it.

```
warning: LF will be replaced by CRLF in <filename>.
```

**Step 3.** Usually, that's all. But some teammates might add an ESLint (or similar code formatter) rule to have all line-endings as LF.

This is tricky because tools like ESLint check the current file buffer and informs you of warnings and errors on the fly. And, in Windows, Visual Studio Code defaults to saving files with CRLF. 

Now, if you have an ESLint rule that enforces line-endings to be LF, then your entire file buffer in Visual Studio Code will be underlined due to warnings/errors! Overwhelming as hell!!!

This is pain, and that's what happened to me once. Untangling that tuxedo situation is how I started investigating the case of CRLF vs LF in Git and finally wrote a LinkedIn post about it!

To fix:
1. Try not having such an ESLint rule. One that strictly checks line-endings to be LF or CRLF. 

2. Create an `.editorconfig` file in project root with:
```ini
root = true
[*]
end_of_line = lf
```
Then install the EditorConfig extension. This way, Visual Studio Code will not save the file with CRLF (the default in Windows), rather will follow the `end_of_line` option.

> Tracer bullets let you home in on your target by trying things and seeing how close they land. 
  *~ Tip #20 from the book "The Pragmatic Programmer"*

---

In realms of code, where logic weaves its spell,
A hunter's instinct, secrets to tell.
Not sights and rifles, but keyboards alight,
Tracer bullets whisper, guiding you right.

No reckless blasts, no chaos unleashed,
But calculated probes, errors appeased.
Small, focused experiments, like arrows take flight,
Testing assumptions, bathed in logic's light.

A function rewritten, a line rearranged,
Each change a tracer, its purpose unchained.
Does it hit the mark? Does the error recede?
Or veer off course, planting doubts to seed?

Feedback's echo, a compass so true,
Guiding adjustments, till solutions accrue.
Results unfold, like stories untold,
Tracer bullets whispering, "Be bold, be bold."

Iteration's dance, a spiraling quest,
Refactoring's chisel, putting flaws to the test.
With each tracer fired, the target grows clear,
A symphony of logic, banishing fear.

So let your code sing, with experiments' grace,
Tracer bullets blazing, leaving no trace.
For in the hunt for truth, where errors reside,
Small steps and quick tests, are wisdom's true guide.

Leave behind the shotgun, the blundering blast,
Embrace the tracer's whisper, its purpose steadfast.
And in the realm of code, where logic takes hold,
Tracer bullets lead you, to stories unfold.

So raise your keyboard, a hunter's keen eye,
Let tracer bullets guide you, as you code and fly.
For in the digital landscape, vast and unknown,
Small, focused probes pave the way, to a software throne.

Web Socket Intro
Tags: webdev, websocket, programming, tutorial
Published: 2024-01-04 13:44:36

**Web sockets** are a way of creating a persistent connection between a client and a server, allowing for real-time communication and data exchange. Web sockets are useful for applications that require fast and interactive features, such as chat, gaming, or live updates.

**Next.js** is a framework for building React applications that supports server-side rendering, static site generation, and incremental static regeneration. Next.js also provides an easy way to integrate web sockets with your application using the built-in API routes feature.

In this blog post, I will show you how to create a simple chat app using Next.js and web sockets. We will use Socket.IO, a popular library for web socket communication, and MongoDB, a document-based database, to store the chat messages.

The steps are as follows:

1. Create a Next.js project and install the dependencies.
2. Set up the MongoDB database and the **Socket.IO** server.
3. Create the chat UI using React components and Tailwind CSS.
4. Connect the client to the **Socket.IO** server and handle the chat events.
5. Deploy the app to Vercel, a hosting platform for Next.js applications.

Let's get started!

Button/s not doing as expected
Published: 2024-01-04 13:20:21

I am very new to Android Studio and I am learning as I go. a Friend of mine asked me to help develop a "Time and attendance" app for him. I got the first activity done, but now with the second activity, I am stuck on some of the buttons.

I have a "back arrow" button and a "send button". The "back arrow" button is working, but with warnings:

1. Function "onBackArrowClick" is never used
2. Parameter 'view' is never used

The "send button" navigates back to the main activity when clicked which should do the following:

1. generate a random verification code and send the code to the email address entered into the email input field.
2. it should also start a timer that counts down

I assume that there is something wrong with the "view" parameter I am using for the "onClick".

Is there something I need to provide so you can understand better?
Open Source Confusion
Tags: opensource
Published: 2024-01-04 13:19:23

Is the concept of open source unclear to you? People in open source are confused too. With its democratisation and the absence of appropriate definition, even specialists are wondering what it means.

There is a variety of interpretations for the notion of open source. It's very likely that the person you're talking to won't have the same one. Open is a vague term, but so is source.

Within the notion of «open source», you have a literal meaning about sources availability, a kind of conventional meaning suggested by the (controversial) Open Source Initiative (OSI), some potential implicit such as the (open) collaboration dimension, mixed with the idea that "source" may be broader than software in digital resources.

Depending on the background, the meaning of open source will be a mix of these various elements.

You end up with some folks sharing their content with sources under open license with restriction believing that collaboration is embedded in the notion, those better informed (≠ right) who don't recognise this as open source because it doesn't meet the OSI's licensing criteria, or you can have the company who absolutely don't care about collaboration just releasing resources under conventional open license.

Multiple and contradictory interpretations, causing a great deal of misunderstanding.

We can witness a growing number of people trying to understand open source and raise this ambiguity.

Around this implicit collaboration, some people try to distinguish between «the letter of the law» and the «spirit of the law», the open source [artifact] and the open collaboration: https://haacked.com/archive/2012/02/22/spirit-of-open-source.aspx/

Others could debate on the fact that open source may not be about software despite we commonly link open source to software. «Open source, not just software anymore»: https://ben.balter.com/2014/01/27/open-collaboration/

We're having a confusing term with multiple meanings composed of polysemous words.

To claim that there is no definition is in fact blasphemy for part of the open source community, as there is a set of license criteria called the Open Source Definition (OSD), hosted by the OSI.

In fact, this pseudo-definition probably adds to the confusion. While claiming to define open source, it says nothing about collaboration or anything other than software.

The OSD define a really strict set of license, without restrictions. Carefree people leaving their resources and their sources online, thinking it's open source but being told that it's not. Passionate debates where it's explained that when you open a source, it's not open source.

The meaning of open source is claimed to be defined by the Open Source Initiative, enforced by some folks, contested elsewhere. “Open Source” Is Nobody’s Property: https://writing.kemitchell.com/2020/05/11/Open-Source-Property

Several layers of confusion with a conflict on top, the important thing is to understand that we don't understand. Confusion is normal, clarity is suspicious.
My Future On DEV…
Published: 2024-01-04 13:12:42

So… this post feels weird. I didn’t really expect to say this, but I’m sort of stepping back. I’m still going to be writing content, but it’s going to change. 

**1.** My long term project with the AI-Internet-Quest, is canceled. The post asking for funding is deleted.

**2.** My posts will become a bit less frequent, more like once every two weeks.

**3.** My posts will be longer, and more large-scale (when you see the first post [Interviewing DEV Team Members], you’ll know what I mean).

**4.** I will be posting more _videos_ on the platform more often, sometimes they’ll correlate to my posts, sometimes not! But mostly tech-based. 

That’s really all for now, but if anything changes this will be updated.
