🌐 Resource Preloading in HTML | One Byte Explainer
Tags: devchallenge, cschallenge, computerscience, beginners
Published: 2024-06-15 06:09:49

*This is a submission for [DEV Computer Science Challenge v24.06.12: One Byte Explainer](https://dev.to/challenges/cs).*

## Explainer

<!-- Explain a computer science concept in 256 characters or less. -->

Resource preloading in HTML can be achieved using the `<link>` element with the `rel` attribute to hint at the browser about resources that will be needed soon. Fetching resources in advance improves load time and webpage performance.

## Additional Context

<!-- Please share any additional context you think the judges should take into consideration as it relates to your One Byte Explainer. -->
Here are some options you may consider :

1. `rel="preload"`: Actively fetch the resource and cache it, as needed for current navigation.
2. `rel="prefetch"`: Fetch the resource in advance as it is needed for follow-up navigation.
3. `rel="dns-prefetch"`: Perform DNS resolution for the resource for easy fetching later.
4. `rel="preconnect"`: Perform a connection request to the resource and establish a connection for easy fetching later.
5. `rel="prerender"`: Preload the resource in the background. However, one should note that this might negatively affect the user's bandwidth.

Made a simple Tic-Tac-Toe game
Tags: python, vscode, github
Published: 2024-06-15 05:47:47

This was one of my academy's projects. It was to pick a topic out of a list and I picked TTT. I got a little side tracked in making is so it took me a little bit longer to make it but if i stayed on track it could've taken me a day. I just did a simple grid layout using tk and took user inputs to assign a simple player one and player two interaction. it is a 3 x 3 clickable grid. In short, this project showed me a nice proper semi productive way to use all of the things i learn into one game.
Here is the link to the game:

"this" Keyword in OOP
Tags: devchallenge, cschallenge, computerscience, beginners
Published: 2024-06-15 04:58:44

_This is a submission for [DEV Computer Science Challenge v24.06.12: One Byte Explainer](https://dev.to/challenges/cs)._

## Explainer
<!-- Explain a computer science concept in 256 characters or less. -->

In a bakery, each baker has their own recipe book. When a baker says "this recipe," they mean a recipe from their own book. Similarly, in programming, `this` refers to the current object's properties and methods, like a baker's personal recipes.

## Additional Context
<!-- Please share any additional context you think the judges should take into consideration as it relates to your One Byte Explainer. -->

In simple terms, think of `this` as a way for an object to say "me" or "myself" to refer to its own data and functions.

* The `this` keyword in object-oriented programming refers to current instance of class. 

* In a method, using `this` can help distinguish between class attributes and parameters with the same name.

* It can also be used to pass the current object as a parameter to other methods or constructors.

The Power of Embeddings in AI
Published: 2024-06-15 04:45:07

## Introduction

Embeddings have become a cornerstone in natural language processing (NLP) and
machine learning. They transform words, phrases, or documents into vectors of
real numbers, allowing algorithms to effectively interpret and process natural
language data.

## What are Embeddings?

Embeddings are data representations that highlight relationships and
similarities between data points. They are low-dimensional, continuous vector
spaces where similar data points are mapped close to each other, making them
useful in NLP and computer vision.

## Types of Embeddings

There are several types of embeddings, each designed for specific
applications:

## Storage of Embeddings

Efficient storage of embeddings is crucial for performance and scalability.
Options include on-disk storage, in-memory storage, and cloud storage
solutions, each with its own advantages and trade-offs.

## Applications of Embeddings

Embeddings are widely used in various applications:

## Embeddings in Large Language Models (LLMs)

In LLMs like GPT-3 and BERT, embeddings play a crucial role in understanding
and generating human-like text. They reduce the complexity of language data,
enabling models to process large volumes of text efficiently.

## Benefits of Using Embeddings

Embeddings offer numerous benefits, including improved model performance,
efficiency in handling large datasets, and versatility across different
applications.

## Challenges with Embeddings

Despite their advantages, embeddings come with challenges such as
dimensionality issues, storage and computational costs, and bias and fairness
concerns.

## Future of Embeddings

The future of embeddings looks promising with advancements in embedding
technologies and their integration with emerging AI technologies, leading to
more dynamic and context-aware systems.

## Real-World Examples

Examples of embeddings in action include the use of Word2Vec in e-commerce for
personalized recommendations and graph embeddings in social network analysis
for tasks like node classification and link prediction.

## Conclusion

Embeddings are a pivotal component in modern AI applications, bridging the gap
between human-like understanding and machine processing capabilities. Their
strategic importance lies in enhancing the intelligence and applicability of
AI systems across various sectors.

emacs org感觉挺好的
Published: 2024-06-15 04:37:41

我看网上别人一直喜欢吹emacs的org文档编辑，我原以为就是和markdown一样的东西，本来就会。
最近不再使用jetbrains系列的软件，感觉就jupyter的插件比较好用，现在用vscode的替代，一直尝试用用emacs里面的ein插件，发现这个有bug，已经好久不修复了。
vscode的jupyter的可能是插件安装太多了，有时候死机，只有强制退出才能搞其他的。

我平时写代码主要还是emacs，这个代码搜索，编辑还是emacs最强。
折腾emacs感觉永远都有学习的，所以我又没事学了下org，才发现org其实可以实现jupyter差不多的功能，其实我对jupyter的使用要求不高，就是有时候执行命令，然后把结果记录下来。
看来vscode的ipynb可以不用了，emacs可以跑全套了。
