Exploring Text-Based Content on the Gemini Protocol

=> ↺ Exploring Text-Based Content on the Gemini Protocol

Picture the web. Websites and all that, right? Now, imagine getting rid of CSS, Javascript, cookies, and nosy request headers. Replace HTML with something simpler that looks more like Markdown. What’s left is the Gemini protocol, and it’s slowly been building a user base in the last few years. If you’re old enough to remember Gopher, it’s kind of like that. Or Maybe the HTML 2.0 days of the web.
With Gemini, what you see is cleaner and loads faster. It’s just the text, and you control how it looks. No CSS, no forms, only text-based content. For search engines and similar applications, there’s a text input query, but that’s about as complicated as it gets. It’s not trying to be the web, just a place for readable content.

An alt Decision Tree Using Only :has()

=> ↺ An alt Decision Tree Using Only :has()

I use the CSS :has() pseudo-class to provide an interactive alt text decision tree (from the W3C WAI Tutorial) that uses no script. It is progressively enhanced, so browsers without support for :has() still get all the content.

How To Save Traffic With Apache2's mod_deflate

=> ↺ How To Save Traffic With Apache2's mod_deflate

In this tutorial, I will describe how to install and configure mod_deflate on an Apache2 web server. mod_deflate allows Apache2 to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.
Compressing files causes a slightly higher load on the server, but in my experience, this is compensated by the fact that the clients' connection times to your server decrease a lot. For example, a modem user that needed seven seconds to download an uncompressed HTML file might now only need two seconds for the same, but compressed file.

Setting up my cloud desktop

=> ↺ Setting up my cloud desktop

With VNC up and running, I added the AWS Linux server to my Tailscale network so I can route all VNC traffic through that, instead of using the public IP (yep, have ufw restricting it). My Raspberry Pi can now talk with the AWS Linux server via tailscale (configured it to have a restricted one-way communication, to protect my home network). Neat.

How to Create a Windows Virtual Machine in Linux With KVM

=> ↺ How to Create a Windows Virtual Machine in Linux With KVM

Running a Windows virtual machine alongside Linux has its benefits. With a Windows virtual machine set up, you don't have to wrap your head around compatibility layers or look for open-source alternatives to your favorite Windows apps. Additionally, if you're a developer, it becomes easy to test your software on multiple operating systems.
Kernel-based Virtual Machine, or KVM is your best bet when it comes to setting up a Windows virtual machine on Linux. But how do you go about creating a new KVM and installing Windows on it?
