"After switching to an HHKB keyboard, there were no arrow keys, so I naturally wanted to minimize arrow key usage when editing text. Under various external factors, I started learning Vim and discovered that pairing it with VSCode
From a UI perspective, frontend and mobile development face similar challenges. Although the languages and development approaches may differ, we both need to build intuitive user interfaces. Naturally, both worlds encounter analogous problems—component-driven development, state management, data flow, handling side effects (API calls or I/O), and so on. To me, this makes it a great space for cross-pollination and learning from each other.
Perhaps having accumulated more experience, my perspective on things seems to have broadened. In 2020 and 2021, I began exploring a wide range of fields—such as Arduino, tinkering with Raspberry Pi, diving into AVR, picking up STM32 dev boards to play with, and learning PCB design and 3D printing. I hoped that beyond frontend development, I could integrate with other domains to create more of what I truly want to build. Now in 2022, after two years of exploration, I hope this becomes a breakthrough year where I can produce tangible results.
This morning, I came across the article "Leaving MySQL." If there's a key takeaway from the post, it's probably what the author wrote: "MySQL is a pretty poor database, and you should strongly consider using Postgres instead."
Polly is an Amazon Web Services (AWS) cloud service that converts text to speech. While text-to-speech itself is nothing new, Polly does an excellent job of generating natural-sounding voices based on sentence structure, making it a tremendous boon for language learners. Beyond that, its potential applications are vast—from generating voiceovers for subtitles, scripts, and narration, to dialogues, or even recording entire podcasts directly with Polly.
To me, the invention of the radio is truly magical: sound can travel across vast distances purely through radio waves, and then be reconstructed and played back through a receiver. In this post, I try building a simple DIY radio circuit to better understand the principles behind it.
The new anime *Blue Period* on Netflix is great. It tells the story of a high school student who falls in love with painting and aims to enter Tokyo University of the Arts.
When building USB applications with AVR, there is really only one key factor: whether the chip itself has built-in USB support. Currently, the ATmega32u4 is probably the only one still in production, but with ongoing semiconductor shortages, it's virtually impossible to buy.
In early 2021, the Raspberry Pi Foundation released the Pico microcontroller. It was very affordable—costing just around 100 TWD—and featured a particularly interesting capability: PIO. With a specialized assembly language and architecture, it allows you to implement various communication protocols without consuming main processor resources.
WebGL does not support lines with a lineWidth greater than 1, and even Three.js lacks built-in support for adjustable line widths. This led to building a custom line implementation from scratch.
I feel this book will eventually be translated into Chinese, so while it is currently only available in Japanese, I wanted to share my reading notes. Spanning over 700 thick pages, it’s even been nicknamed a "blunt weapon book" (#鈍器本) in Japan and topped bestseller lists. Packed with rich content, it is perfect for beginners who want to systematically learn a subject but don’t know where to start.
When browsing the web, we often distinguish services by subdomain. However, telling whether a site is a subdomain or whether two sites are SameSite is not as simple as it seems.
shiki is a syntax highlighting package that is relatively newer and less well-known compared to alternatives like highlightjs and prismjs. Because it supports more languages, is easier to configure, and comes with plenty of built-in themes, I went ahead and replaced my existing prismjs setup with it.
In frontend applications, we often encounter scenarios where a value displayed on the screen is computed from other values, or undergoes some calculation before being rendered. Typically, this kind of processing can be simplified using useMemo.
I had always been used to switching tabs directly using iTerm2's tab feature in the terminal. While there was nothing really wrong with that, ever since discovering how useful `tmux` is, I've moved all my terminal operations over to tmux.
Long before the technological singularity arrives, Earth may already be struggling to bear the weight of the global economic system. We might only be able to maintain our current lifestyle because we live in more developed countries at the upper tiers of the supply chain. But digging into the underlying signs reveals an increasingly concerning reality.
From NAND gates to Turing completeness, wiring circuits and building components entirely from scratch. Through visualization, this game turns code-writing into draggable logic gates, with real-time interactivity that makes observing truth table changes much easier for players.
Recently, the term NFT has become a trendy buzzword, with everyone rushing to "collect" them. However, many people hold flawed understandings. Here is a compilation of common misconceptions.
Linear output is the foundation of economic systems; exponential output can transform human lifestyles.
This article merely expresses my personal viewpoints and reflections, with no intention of criticizing fellow industry professionals. I believe the current frontend domain (referring specifically to web development here) is gradually maturing. With frontend frameworks adopting the core philosophy of componentization and reactive mechanisms, paired with framework-specific syntax, development methodologies, and philosophies, they can handle the vast majority of use cases.
