(I’m really so frustrated that I had to write a blog post to vent my experience.)

One day, while I was changing my Display Name, I encountered a 500 Internal Server Error. After searching online, I realized that the situation was more complicated than I initially thought…

Twitter has two types of names: the Handle, which is unique and cannot be duplicated, forming the foundation of the service. However, the Display Name can be duplicated, so there should be no reason for errors to occur…

Are you like me? You’re in class, asked to write Verilog using Quartus II, only to find out it’s a Windows-only application? Σ(’◉⌓◉’) This leaves us students with Macs or Linux installations staring blankly at our screens. Don’t worry! This post will tell you how to handle Verilog design on macOS and Linux, and even do some proof-of-concept testing! * (You can even run it on Android phones/tablets!)

Hello everyone! Recently, I had an old, unused Chromebook lying around. Thinking it’s a shame to let it gather dust, I got the idea to turn it into a simple Docker development server. After all, using a lightweight machine for lightweight services makes many things much more convenient.

To save money on commuting between Kaohsiung and Tainan recently, I purchased the Southern Taiwan (Nangaoping) TPASS. This guide provides some strategies for exploring Kenting affordably. If you’re a foreigner visiting Taiwan and plan to stay in Southern Taiwan for close to a month, purchasing the TPASS is also highly recommended.

On this trip, I traveled to Japan to seek out a living fossil in the integrated circuit forest.

A few days ago, I felt unwell after getting a vaccine, so I paused updates for a while. And finally, the semester is over! Although there will be many decisions influenced by what I made during the finals period, I now have more time to think about more details (´▽｀)

As the project progressed, I realized more and more that designing a computer architecture is not such a simple task… Initially, I just brainstormed and simulated in my head, but later on, I found that Uxn’s basic instruction set alone has 32 instructions, and with 3 mode combinations, there are a total of 256 instructions. Designing a CPU for 256 instructions is truly a challenging endeavor for a university freshman…

In the previous article, I mentioned that I had completed the design and implementation of Register A, B, and the ALU. However, during the actual implementation process, I found that when operating and debugging signals, relying solely on LEDs for visual inspection made it difficult to directly observe specific signal changes. Therefore, I decided to implement a logic analysis tool.

Since the blog was set up relatively late, a lot of content has accumulated, which I’ll be catching up on in the next few posts.

The designs for the components I’m about to introduce were actually implemented on breadboards several years before this project even began. This time, with the school’s final project deadline approaching, I decided to revisit my previous work and incorporate new ideas, embarking on a brand-new CPU project.

As the semester drew to a close, each of us was required by our teacher to submit a project for the Digital Circuit Design course, assembled using at least the 74 series ICs. That’s when a bold idea suddenly struck me: why not design a computer?
