This blog supports RSS feed (all content), you can click RSS icon or setup through third-party service. If there are special styles such as code syntax in the technical article, it is still recommended to browse to the original website for the best experience.
我會把一些不成文的筆記或是最近的生活雜感放在短筆記，如果有興趣的話可以來看看唷！
When using CSS for layout, we process it with corresponding CSS based on styles. Sometimes, we even need to use JavaScript to accomplish it. However, in CSS, there are actually many pseudo-classes that can simplify CSS if used properly. This can also reduce unnecessary JavaScript implementations and is no longer limited to only a few supported browsers as it used to be.
Recorded the process and thoughts of migrating the blog from Gatsby to Next.js. Includes the technologies used and implementation details, etc.
In the C language, you can use strlen to obtain the length of a string. However, there are certain things to be aware of when using it.
Although some people may think, "Oh no, another framework," Remix does have its unique features. If you have gone through the documentation and followed the most obvious,
Even in microcontrollers, there are various interrupts that can be used, so the execution of the code may be interrupted. This can be managed by using atomic operations.
In node.js, it is common to use the fs module to manipulate files. However, when dealing with high throughput scenarios, any IO-related operations should be handled with caution.
Originally, I planned to organize and share what I have done, but after finishing the organization, I realized that there isn't much to talk about. So, I'll just record it in a chronological manner.
The course seems to cover a wide range of topics, including data science, climate change modeling, Ray Tracing, partial differential equations, statistics, image processing.
I have always been curious about one thing. My friends around me usually don't comment on things on the internet, such as leaving comments under a post or expressing their opinions on Twitter. However, if they ask a question in a private group, they usually receive good advice. What I have realized is that people actually enjoy giving advice and opinions, so why don't most of us comment frequently on the internet?
There are two males and one female student in first grade who are sharing infinite alerts.
Many websites now incorporate the process of measuring Web Vitals to identify areas for improvement through quantifiable metrics. However, what fewer people know is that Sentry actually introduced statistical functionality for Web Vitals earlier, which allows developers to track various indicators such as LCP, FP, and CLS. This enables developers to view relevant charts in the backend, and even includes average values, which is quite thoughtful.
Today in the Japanese software development community, the hottest news should be the "Coinhive incident". This lawsuit is due to website operators placing mining scripts on their websites, which start mining when users access the web page. This behavior has been charged with "unauthorized electromagnetic record (obstruction of computer use crime)", initiating a series of legal proceedings.
After switching to the HHKB keyboard, I no longer have arrow keys. When editing text, I naturally try to minimize the use of arrow keys. Influenced by various external factors, I started learning Vim and found it to be quite useful, especially when paired with VSCode. Here, I would like to share some insights and tips with those who are interested.
From a UI perspective, the challenges faced in frontend and mobile development are similar, despite the differences in languages or development approaches used. We all need to create a user-friendly interface. As such, we will encounter similar problems such as component-based development, state management, data flow, and managing side effects (API or IO), which I find to be a great area for mutual learning.
This morning I saw this article called "Leaving MySQL". If there is one key point in this article, it would probably be what the author wrote: MySQL is a pretty poor database, and you should strongly consider using Postgres instead.
Polly is one of the services on the Amazon cloud platform that can convert text into speech. Although text-to-speech is not uncommon, Polly can generate natural-sounding voices based on sentence structures, which is a great boon for language learners. In addition, it has a wide range of applications, such as converting subtitles into speech, scripts, narrations, dialogues, and even the possibility of using Polly to record podcasts directly.
To me, the invention of the radio is quite miraculous. Through wireless transmission, sound can actually travel to such distant places and be played back through a radio. This article attempts to create a simple radio circuit to understand the underlying principles.
Recently, the new anime "Blue Period" on Netflix is very good. The story is about a high school student who falls in love with drawing and enters Tokyo University of the Arts.
The key point of using AVR for USB is whether the chip itself has built-in USB support. Currently, only ATmega32u4 is still in production, but it may also be difficult to obtain due to semiconductor supply shortages.
In early 2021, Raspberry Pi released the pico microcontroller, which is quite affordable at just over 100 Taiwanese dollars. One interesting feature of it is PIO, which allows the implementation of different communication protocols using specialized assembly language and architecture without consuming the resources of the main processor.
In the field of computing, when performing calculations on signals, sampling is typically done on discrete data, hence it is called Discrete Fourier Transform (DFT). Fast Fourier Transform (FFT) helps us convert time-domain signals into frequency-domain signals, facilitating further analysis.
This book feels like it will eventually be translated into Chinese. While there is currently only a Japanese version, I want to share my reading experience with everyone. This book is thick, with over 700 pages, and is even referred to as the "#BluntInstrument" in Japan. It has also made it onto the bestseller list. The content inside is very substantial and is suitable for beginners who want to learn a subject thoroughly but don't know where to start.
WebGL does not support lines with a lineWidth greater than 1. Even Three.js does not have support for adjustable line widths. Therefore, I started working on my own implementation for lines.
When browsing the web, we often use subdomains to differentiate the content of services. However, determining whether a website is a subdomain or if two websites are SameSite is not as straightforward as it may seem.
In frontend applications, it is common to encounter a situation where the displayed value is calculated by combining other values or undergoes some calculation before being inserted into the UI. Usually, this type of processing can be simplified using `useMemo` to reduce code complexity.
shiki is a package that provides syntax highlighting for code. It is relatively newer and less well-known compared to other packages like highlightjs and prismjs. The main reason is that it supports a wider range of languages and is easier to configure. It also comes with a good variety of built-in themes, making it convenient to replace prismjs.
I have always been accustomed to using the terminal by directly switching tabs through the tab feature of iTerm2. There is nothing wrong with doing so, but ever since I discovered the advantages of `tmux`, I have moved all my terminal operations to tmux.
Before the advent of technological singularity, it is feared that the Earth will soon be unable to sustain the global economic system. Perhaps we are able to maintain our current way of life simply because we live in more advanced countries and are positioned at the top of the supply chain. However, upon closer examination of various signs, it becomes increasingly worrisome.
From NAND logic gates to Turing completeness, everything is self-assembled by pulling circuits and assembling components. This game turns the writing of code into drag-and-drop logic gates through visualization, making it easier for players to observe the changes in truth tables in real-time.
Recently, the term NFT has become a trend, and everyone is rushing to "collect" them. However, there are often misunderstandings, so here are some common misconceptions.
