Two New Web Projects

• Tic Tac Toe
• Game of Life

New Page: Web Project (Jan. 10th 2025)

Added Web Project page. I will post web-related project there, I’m not really into web development so maybe don’t expect frequent uploads there. Best way to experience it is to try it yourself:

New Features on Yuk’s Blog (Jan. 9th 2025)

Table of Content

You can click on the entries to jump to the desired section. (On top of this page). Spoilers:

(Deprecated)

Linkage

Table of content and certain headings will now have linkage “🔗” to them (not every post). Clicking on them will copy the link to your clipboard, you may use this link to access the post and immediately jump to the heading section upon loading the page for convenience.

Animation Update

Various elements have been given animations because why not.

Blockquotes Update

Blockquotes are now more consistent with Codeblocks and is now affected by extend / collapse button.

• Blockquotes will look like:

This is a blockquote

Sure! Here’s a long paragraph for you: The rapid advancement of technology in recent decades has brought about profound changes in various aspects of society, from the way we communicate to the way we work and live. With the rise of artificial intelligence, automation, and data analytics, many industries have experienced significant transformations, often leading to increased efficiency and innovation. However, these advancements have also raised important questions about the future of jobs, privacy, and ethical considerations. As automation continues to evolve, it is unclear what the long-term impact will be on the workforce, as many tasks once performed by humans are now being carried out by machines. Additionally, concerns about data privacy have become more prominent, with large-scale data collection and surveillance becoming commonplace in many parts of the world. In response to these concerns, governments, organizations, and individuals are increasingly looking for ways to balance innovation with privacy protection and ethical responsibility, recognizing that the future of technology will likely be shaped by these discussions. Despite the challenges, the potential for technological progress to solve complex global issues, such as climate change and healthcare, remains vast, offering hope for a future where technology serves as a force for good.

Table Formatting

Tried my best with tables:

To Top of Page Button

Added a button at the footer of posts to jump to the head of the page.

Vietnamese Support

The blog has support for Vietnamese content now.

New Features on Yuk’s Blog (Oct. 1st 2024)

Since I don’t have time or even a good grasp on the recent development of my blog, I want to quickly summarizes and explain the new features on my blog here.

Light / Dark Mode Support

I’ve added light / dark mode support for the site, simply click the ☀️ / 🌙 button which will usually be located at the top right of the header to toggle between them.

Codeblocks Update

• Collapse / Expand Codeblocks: Codeblocks on this blog can be quite lengthy at times, so I’ve added the 🔼 / 🔽 button at the top right of each of the codeblocks for you to collapse or expand them to your liking. On load, all codeblocks will be expanded by default, you can use the big 🔼 / 🔽 button at the top right of the header to collapse or expand all codeblocks in the current post.
• Copy Code: I’ve added the 📄 button to codeblocks, which will allow you to copy the entire codeblock with the click of a button, below is a dummy codeblock:

def binary_search(arr, x):
    low = 0
    high = len(arr) - 1
    mid = 0

    while low <= high:
        mid = (high + low) // 2

        if arr[mid] < x:
            low = mid + 1
        elif arr[mid] > x:
            high = mid - 1
        else:
            return mid
        return -1
