🌱

How to Separate a Sectional Sofa

Sectional sofas are designed with hooks and latches that connect individual pieces, making them easy to detach, move, and rearrange.

• Locate the Connectors: Find the hooks, clasps, or latches that join the sofa sections. These are usually located underneath or between the sections.
• Detach the Sections: Gently lift or slide one section to unlock it from the connectors. Be careful not to force it to avoid damage.
• Move and Rearrange: Once separated, you can easily move, rearrange, or store the individual pieces as desired.

How Much Does A Piano Weigh?

There are three primary types of pianos: Grand, Upright, and Electric. The average upright piano weighs between 200-1,000 pounds.

• Grand pianos: The largest type of piano, also known as a Horizontal Piano due to its horizontal string alignment. Offers a rich, full sound but requires significant space.
• Upright pianos: The most common type of acoustic piano, also called a Vertical Piano because its strings are strung vertically. Designed to be more compact, making it ideal for smaller spaces.
• Electric pianos: Also known as Digital Pianos, they are popular among beginners and traveling performers. Lightweight and portable, making them easy to move and maintain.

🌱

WWE Raw and SmackDown

WWE’s “Monday Night Raw” and “Friday Night SmackDown” are the company’s two flagship programs, each offering unique content and styles to engage a wide audience.

• Both shows feature scripted storylines and predetermined match outcomes, which are standard in professional wrestling to enhance entertainment.
• Despite being scripted, the physical performances are very real, requiring wrestlers to undergo rigorous training to perform moves safely.

Personally, I found some segments uncomfortable to watch during last Saturday’s broadcast.

2025-01-13 TIL: Custom URI Schemes and Standard Web Links

💻

Custom URI Schemes and Standard Web Links

Custom URI schemes are application-specific protocols that allow apps to communicate with each other or be launched directly. They are defined by developers to enable deep linking into specific parts of an app.

• Example: A custom URI like myapp://section/page can open the “page” in the “section” of the app named “myapp”.

Standard web links use common protocols like HTTP or HTTPS to direct users to web content. When integrated with app linking mechanisms, they can open corresponding content within an app if installed, or fallback to a web browser if not.

• Example: A link like https://www.example.com/page can open the corresponding page within an app if installed; otherwise, it opens in the browser.

Here’s how these linking mechanisms are represented across major platforms:

Key Differences:

• Security:
  • Custom URI Schemes: Less secure; any app can register the same scheme, leading to potential conflicts or malicious hijacking.
  • Standard Web Links: More secure; rely on domain verification to ensure only authorized apps handle the links.
• Fallback Behavior:
  • Custom URI Schemes: If the app isn’t installed, the system may not know how to handle the link, potentially leading to errors or no action.
  • Standard Web Links: Provide a seamless user experience by opening the app if installed or defaulting to the web browser if not.
• Implementation Complexity:
  • Custom URI Schemes: Simpler to implement but require careful management to avoid conflicts.
  • Standard Web Links: Require setting up domain associations and hosting verification files but offer a more robust solution.

HTML Is Actually a Programming Language

HTML is arguably the most significant computing language ever created. Its simplicity and accessibility are its greatest strengths.

What other programmers might say dismissively is something HTML lovers embrace: Anyone can do it. Whether we’re using complex frameworks or very simple tools, HTML’s promise is that we can build, make, code, and do anything we want.

htmx

htmx (also stylized as HTMX) is an open-source front-end JavaScript library that extends HTML with custom attributes that enable the use of AJAX directly in HTML and with a hypermedia-driven approach.

• These attributes allow for the dynamic definition of a web page directly in HTML and CSS, without the need for writing additional JavaScript.
• These attributes allows tasks that traditionally required writing JavaScript to be done completely with HTML.
