Introducing P2P Matrix
P2P Matrix is about more than just letting users store their own conversations: it can also avoid dependencies on the Internet itself by working over local networks, mesh networks, or situations where the Internet has been cut off. Even more interestingly, without homeservers, there is nowhere for metadata to accumulate about who is talking to who, and when - which is a legitimate complaint about today’s Matrix network, given the homeservers of all users in a given conversation necessarily have to store that conversation’s metadata.

The rise of React
On the social, cultural, and technological impacts of the increasingly ubiquitous frontend framework.

昨天我分享了一篇如何使用 PlantUML 这门简单的语言来绘制复杂的活动图、流程图和组件图等,有的同学看到了以后,询问我,“外行需要多长时间才能学会这玩意儿呀?”,这个问题不知道该如何回答,因为我并不认同“外行”这个词。我始终认为,在编程这件事情上,每个人都是内行,每个人也都是外行。事实上,从不了解 PlantUML 到能够参考文档绘制出复杂的流程图,我也就学了一个上午,边学习、边实践、边分享,于是就会了。

Grid.js is a Free and open-source HTML table plugin written in TypeScript. It works with most JavaScript frameworks, including React, Angular.js, Vue and VanillaJs.

How To Become A Hacker
Sixteen years later, I thought it’d be fun to write my own version of How to Become a Hacker to supplement ESR’s original: something I would have liked to have read myself at thirteen that focuses on some other aspects I would have found helpful too. A lot of posts about programming and related topics are rallying cries, trying to persuade you to adopt a specific programming language, framework, operating system, or specific way of doing things. This post does less of that and while I make some suggestions, it’s a more tempered view. Its goal is to fill the niche of what I think I would have liked to have read after ESR’s original post (so you should read that one first).


Google Is Not God of The Web
Almost exactly two years ago, I warned that Google was on track to replace God of us all. Last month, The Verge’s Dieter Bohn reported that Google plans to begin accounting for “page experience” in its search rankings beginning in 2021. I’m not a “real” web developer – nor do I mean to dictate to a single one – but I know enough theory to note that of this “core web” education operation centered around web.dev is operating on some irritating assumptions. 另附:Google’s Core Web Vitals: ensuring your site is ready for Google’s next major update.

Software Engineering Within SpaceX
SpaceX also made use of Chromium and JavaScript for Dragon 2 flight interface. I am not sure how that passed the certification. I assume it was allowed because for every mission-critical input on the display, there was a physical button underneath the display as well. So if in case the screen malfunctioned, the astronauts could potentially make use of the physical buttons.

Serverless Express – Easy APIs On AWS Lambda & AWS HTTP API
Take existing Express.js apps and host them easily onto cheap, auto-scaling, serverless infrastructure on AWS Lambda and AWS HTTP API with Serverless Express. It’s packed loads of production-ready features, like custom domains, SSL certificates, canary deployments, and costs ~$0.000003 per request. 另附:Best practices for REST API design.

Techniques For Designing Your API and Microservices
One way of validating your API and microservice designs is to use some design techniques to surface issues before we commit to our design. Just as we use test-driven development to turn requirements into test cases that we code against, these design techniques help us to design APIs and microservices that meet the needs of our stakeholders. Let’s examine five techniques that can help you validate your API and service designs before, during, and after the design process.

Reducing search indexing latency to one second
One of the key metrics for a search system is the indexing latency, the amount of time it takes for new information to become available in the search index. This metric is important because it determines how quickly new results show up. Not all search systems need to update their contents quickly. In a warehouse inventory system, for example, one daily update to its search index might be acceptable.

Why the developers who use Rust love it so much
Here’s why Rust gets so much love, straight from the Rustaceans themselves. 另附:Announcing Rust 1.44.0.

Ultimate Guide to Python Debugging
Even if you write clear and readable code, even if you cover your code with tests, even if you are very experienced developer, weird bugs will inevitably appear and you will need to debug them in some way. Lots of people resort to just using bunch of print statements to see what’s happening in their code. This approach is far from ideal and there are much better ways to find out what’s wrong with your code, some of which we will explore in this article.

The beauty of Unix pipelines
The Unix philosophy lays emphasis on building software that is simple and extensible. Each piece of software must do one thing and do it well. And that software should be able to work with other programs through a common interface – a text stream. This is one of the core philosophies of Unix which makes it so powerful and intuitive to use.

Introducing Swift AWS Lambda Runtime
Distributed as a Swift package, the Swift AWS Lambda Runtime is designed to help Swift developers build serverless functions for the Amazon Web Services Lambda platform.

Solid - A declarative Javascript library for creating user interfaces
It does not use a Virtual DOM. Instead it opts to compile its templates down to real DOM nodes and wrap updates in fine grained reactions. This way when your state updates only the code that depends on it runs.

React Datepicker 3.0
A simple and reusable datepicker component for React.

HTML5 Boilerplate 8.0.0 Released
It took a little longer than I expected, but we released HTML5 Boilerplate 8.0.0 yesterday. As I mentioned a few weeks ago, it’s the 10th anniversary release, and if I do say so myself, it’s a pretty good way to celebrate 10 years of the project. It was a lot of work getting this one out the door, but I’m really happy with how it turned out.

Rough Notation
Rough Notation uses RoughJS to create a hand-drawn look and feel. Elements can be annotated in a number of different styles. Animation duration and delay can be configured, or just turned off.

Caldera - Server-side execution for React
Caldera is a server-side execution environment for React. Think of it as the Node.js analog to Phoenix LiveView — all of the application logic (including rendering) runs on the server, and DOM updates are sent to the client in real-time.

Introducing Deck 1.0 —The Sketch to Powerpoint converter
Two years back I build an MVP online tool that dealt with the same concept, Sketch to PPT converter. Later on, I decided to enhance the experience and making it a plugin rather than an online tool. With some better performance and enhanced experience here I am introducing Deck — The sketch plugin to convert your designs into an editable PPTX file.

Good Design Vs. Good UX Design
The idea of a product that is aesthetically pleasing being one that has a good user experience is a common misconception.

How To Test A Design Concept For Effectiveness
Getting a client or stakeholder to approve a design concept can be challenging. However, testing can make it easier, as well as ensuring you have the right solution.


Become an Effective Software Engineering Manager: My Book Review and Notes
I wish the book Become an Effective Software Engineering Manager (ebook) existed when I moved from development to management. I was one of the luckier ones: I had a formal apprentice management program with plenty of training, access to senior engineering leaders as mentors within the company, and a circle of hands-on engineering managers to learn from. Even so, this book would have helped me be more strategic about my learning and would have given me more confidence early on.

The future is not what it used to be
This pandemic has provided a relatively brief insight into a future world, one in which virtual and digital has become central to every interaction, forcing organisations and their leaders to go further and to deepen their IT adoption and business change. A world in which omni digital channels become the main customer engagement model, fully automated processes become a primary driver of productivity and the very basis of flexible and transparent supply chains. It is a world in which complete agility is a prerequisite to survival allowing adaptability to continuous changes of habit and behavior.


从 Airtable 为代表的 Nocode 工具开始,到近期因为疫情导致的 Remote 办公风潮的兴起,在面对未来迷茫的时候,答案其实往往蕴藏在过去的历史中。所以本文回溯了电子表格从 1978 年的创造史,到今天 Airtable 的现状,看看能否从历史的浪潮中,找到新的机会所在(或者说找到古典产品经理的尊严😃)。哦对了,从某种意义上说,Excel 是世界上最常用的编程语言和用户界面工具,同时也是使用最多的数据库。
