When Bitcoin Falls, I Finally Understood the Cathedral and the Casino

【2026-02-01】When Bitcoin falls, it becomes easier to distinguish between the casino and the cathedral. As Bitcoin dropped from its $120k peak to around $70k, panic swept through the market once again. During previous major stock market crashes. Price volatility is the casino's noise, while what truly determines long-term returns are those cathedrals that require a century of devotion yet continuously create structural value.

I want to chat with everyone about the changes in my thoughts during this process.

2024 Summary - Continuous Iteration

【2025-02-02】I'm used to taking advantage of the less busy days during the Spring Festival to record what happened in the past year. I think the keyword for this year should be "continuous iteration." I'm increasingly realizing that everyone's most important work is actually themselves. Your life experiences, personality, values, and skills constitute this work itself, and the work needs to be continuously iterated. I plan to use this summary to back up 2024 and start the new version of 2025.

They don't have noise cancellation and are wired, but I love them. I want to share my selection process with you all.

Elon Musk - Book Notes

【2024-04-14】I recently finished reading "Elon Musk" during my morning reading time. I highly recommend it to fellow engineers. Although Musk sometimes acts strangely on X, the book reveals him as a true engineer, a genius skilled at combining technology, business, and cost control, but also a person with many flaws. I'm jotting down some notes for my own reference. After reading this book, as a Tesla shareholder, I am willing to continue holding.

My Minimalist Living Experience

【2024-03-03】Just want to casually talk about minimalism with everyone. I quite like this lifestyle, but that doesn't mean everyone needs to be a minimalist.

I'm Actually 30 Years Old

【2023-12-30】After tonight, I'll actually be 30 years old. I've shamelessly felt like I was only 24, and before that, even more shamelessly thought I was 18. I can't believe how fast time flies. Age feels like a wheel rolling down a mountain, gaining speed as time stretches on. Although my experiences are becoming richer, the perceived length of a year is significantly shorter than when I was a child, and I still feel some regret and melancholy.

Disliking the Atmosphere of the Front-End Entertainment Industry

【2023-12-26】Personally, I really dislike the "front-end entertainment industry" atmosphere. Recently, the "Twelve Zodiac Animals of Front-End" even appeared on Twitter. For a moment, I didn't know if it was self-deprecation or entertainment.

Summary of 2022 - Live Freely

【2023-01-25】Today is the fourth day of the new year 2023. For a procrastinator like me, delaying any further might mean never writing it at all, which can't happen. By the time I'm old, I probably won't remember what happened. To me, 2022 was a year worth recording. This article intends to casually talk about life, tinkering, and work.

What Makes a Good Low-Code Product

【2023-01-02】When it comes to low-code, there are those who love it passionately and those who are decidedly less enthusiastic. There are also those who "pretend" to like it and others who like it without really understanding why. Currently, I find myself somewhat fond of low-code, but only within specific domains where it can significantly speed up the development process compared to traditional coding by skilled engineers. Lately, I've been contemplating the next steps for team efficiency and decided to explore the open-source low-code products in the industry, which might offer some insights.

Front-end Development Workflow Tool Yeoman

【2015-02-21】In the previous article, we introduced Grunt, which can help us automatically manage and run various JavaScript tasks. In the article before that, we introduced the front-end package manager Bower. In this article, we come to introduce Yeoman, a magical scaffold. Yeoman is developed by the Google team and a team of external contributors. Its goal is to create an easy-to-use workflow for developers through the packaging of Grunt (a command line tool for development task automation) and Bower (a package manager for front-end resources such as HTML, CSS, JavaScript, and images). Below I will briefly introduce this magical tool to everyone ...

Front-end Development Workflow Tool Grunt

【2015-02-18】In the previous article, we introduced the front-end package manager Bower. This time, we come to understand the front-end application development workflow tool Grunt. In the process of JavaScript development, we often encounter some repetitive tasks, such as checking if syntax is correct, compressing code, and merging files. In the past, we would choose different tools to complete different tasks, but this felt both complex and time-consuming. But now with Grunt, Grunt was invented precisely to solve these problems. It can help us automatically manage and run various JavaScript tasks, simplifying our workflow ...

Front-end Development Workflow Tools Cmder and Bower

【2015-02-17】Front-end development is indeed not the same as before. If we say that our past front-end development was in the "slash-and-burn" era, then current front-end development has undoubtedly entered the era of "factory production". In recent years, with the emergence of Node.js, many excellent front-end development management tools have appeared, which greatly facilitates our front-end development. Indeed Node.js is the best gift from God to our front-end development engineers. In the following articles, I will introduce some excellent tools needed in the front-end development process: Cmder, Bower, Grunt, Yeoman ...

Performance Optimization in JavaScript Programming Practices

【2015-02-16】Every programming language has its "pain points," and over time, its existing inefficient patterns also continue to develop. JavaScript presents some unique performance challenges, which are related to the way your code is organized. As web applications become more advanced and contain more and more JavaScript code, various patterns and anti-patterns gradually appear. To write more efficient code, please keep these programming practices in mind ...

Ajax Performance Optimization

【2015-02-14】Ajax is the foundation of high-performance JavaScript. It can make page loads faster by delaying the download of larger resource files. It passes data between the client and the server asynchronously, thereby avoiding batch downloading of page resources. it can even get resources for the entire page with just one HTTP request. Choosing appropriate transmission methods and most effective data formats can significantly improve the interaction experience between users and websites ...

High Performance JavaScript - Rapidly Responding User Interface

【2015-02-12】There is a saying that makes sense: "If JavaScript runs for whole seconds, then it is very likely that you have done something wrong...", if the interface responds to user input within 100 milliseconds, users will think they are "directly manipulating objects in the interface". More than 100 milliseconds means users feel they have lost contact with the interface. JavaScript and user interface updates run in the same process, so only one thing can be handled at a time. This means that when JavaScript code is running, the user interface cannot respond to input, and vice versa. Efficiently managing the UI thread is to ensure that JavaScript cannot run for too long, lest it affect the user experience. Managing the running time of JavaScript is very important for the performance of Web applications ...

Algorithm and Flow Control Performance Optimization of JavaScript

【2015-02-07】Like other programming languages, code writing and algorithms will affect the running time of JavaScript. Unlike other languages, JavaScript has limited available resources, so optimization techniques are more important. this study note mainly optimizes JavaScript performance from three aspects of JavaScript loops, conditional statements, and recursion ...

DOM Programming Performance Optimization of JavaScript

【2015-02-06】DOM is an abbreviation for Document Object Model. It is a language-independent application program interface for users to manipulate XML and HTML documents. In browsers, it mainly deals with HTML documents. In web applications, XML documents also often need to be retrieved. DOM API is used to access data in documents. John Hevatin once gave a pertinent metaphor in a speech, imagining DOM and JavaScript as islands respectively, they are directly connected by a toll bridge. Every time ECMAScript accesses DOM, it has to pass through this bridge and pay a "bridge fee". The more bridges passed, the more fees paid. Therefore, if you want to reduce costs, you have to cross the bridge less. Here we come to learn how to optimize this problem ...

Data Access Performance Optimization of JavaScript

【2015-02-05】There are four basic data storage locations in JavaScript: literals, variables, array elements, and object members. Like other languages, the storage location of data will greatly affect its reading speed ...

Comparison of Vue, Angular, Avalon Frameworks

【2015-02-04】Front-end development is no longer the front-end development of a few years ago. It has entered the industrial era from the agricultural era. In recent years, many excellent MVVM frameworks in JavaScript have appeared. Today I compare the advantages and disadvantages of frameworks like Vue, Angular, Avalon ...

Loading and Execution Performance Optimization of JavaScript

【2015-02-03】Managing JavaScript code in browsers is a tricky problem because code execution blocks other browser processes, such as user interface painting. Every time a script tag is encountered, the page must stop and wait for the code to download (if it is an external file) and execute, and then continue to process other parts. Despite this, there are still some ways to reduce the impact of JavaScript on performance ...
