In this blog post, we offer a few pieces of advice for JS developers who want to make the best use of code caching to improve the startup of their websites. This advice focuses on the implementation of caching in Chrome/V8, but most of it is likely transferable to other browsers’ code caching implementations too.
jQuery 3.4.0 Released
So many of us owe so much to jQuery that I just have to feature any of its key updates (even if you might not need it). 3.4 is focused on bug fixes and performance improvements, but we’re told a serious overhaul is on the way for jQuery 4.0. 另附：jQuery Terminal Emulator - web based terminal.

Digging Into The Display Property: The Two Values Of Display
We talk a lot about Flexbox and CSS Grid Layout, but these layout methods are essentially values of the CSS display property, a workhorse of a property that doesn’t get a lot of attention. Rachel Andrew takes a better look in a short series.
JSON as configuration files: please don’t
I’ve recently witnessed the rather disturbing trend of using JSON for configuration files. Please don’t. Ever. Not even once. It’s a really bad idea. It’s just not what JSON was designed to do, and consequently not what it’s good at. JSON is intended to be a “lightweight data-interchange format”, and claims that it is “easy for humans to read and write” and “easy for machines to parse and generate”.

Aroma: Using machine learning for code recommendation
Thousands of engineers write the code to create our apps, which serve billions of people worldwide. This is no trivial task—our services have grown so diverse and complex that the codebase contains millions of lines of code that intersect with a wide variety of different systems, from messaging to image rendering. To simplify and speed the process of writing code that will make an impact on so many systems, engineers often want a way to find how someone else has handled a similar task. We created Aroma, a code-to-code search and recommendation tool that uses machine learning (ML) to make the process of gaining insights from big codebases much easier.
How eBay Governs its Big Data Fabric
At eBay, nearly everything we do is based on data. We deal with structured, unstructured, and semi-structured data, where Hadoop, as a big data platform, has provided key technology features. Keeping pace with the speed of innovation while continuing to help data consumers easily find and consume the data they need guides our architecture and investment in building out eBay’s Big Data Fabric.
Org-Mode Is One of the Most Reasonable Markup Languages to Use for Text
This is about Org-mode syntax and its advantages even when used outside of Emacs. You can type Org-mode in vim, notepad.exe, Atom, Notepad++, and all other text editors out there. And in my opinion it does have advantages compared to the other, common lightweight markup standards such as Markdown, AsciiDoc, Wikitext or reStructuredText.
Launching the Front-End Tooling Survey 2019
How have our front-end tooling habits changed since last year’s results? React and Vue.js made large gains across all of these areas. In fact, in a change from the previous set of results, React was considered the most essential tool in this category for the first time — knocking jQuery off the top spot–with almost a third of respondents replying as such (28.47%). 附：The Stack Overflow Developer Survey 2019 Results .
Front-end Developer Handbook 2019
This is a guide that everyone can use to learn about the practice of front-end development. It broadly outlines and discusses the practice of front-end engineering: how to learn it and what tools are used when practicing it in 2019. It is specifically written with the intention of being a professional resource for potential and currently practicing front-end developers to equip themselves with learning materials and development tools. Secondarily, it can be used by managers, CTOs, instructors, and head hunters to gain insights into the practice of front-end development. 另附：前端九部 - 入门者手册2019。
Launching a YouTube dataset of user-generated content
We are excited to launch a large-scale dataset of public user-generated content (UGC) videos uploaded to YouTube under a Creative Commons license. This dataset is intended to aid the advancement of research on video compression and quality evaluation. We created this dataset to help baseline research efforts, as well as foster algorithmic development. We hope that this dataset will help the industry better comprehend UGC quality and tackle UGC challenges at scale.

React-Redux version 7 resolves the performance issues that were reported with version 6, and lays the groundwork for us to design and ship a public useRedux()-type Hooks API in a later 7.x release. The major change for this release is that connect is now implemented using Hooks internally. Because of this, we now require a minimum React version of 16.8.4 or higher.

The next generation database. EdgeDB combines the simplicity of a NoSQL database with relational model’s powerful querying, strictness, consistency, and performance. EdgeDB is an open-source object-relational database that bakes in support for working with semi-structured data in an attempt at bringing the simplicity of NoSQL to the relational world. PostgreSQL is used under the hood with Edge’s own SQL-esque query language (EdgeQL) compiled to SQL behind the scenes, and this post is a great introduction to EdgeQL and how it works from a developer’s perspective.

Monotype launches the first redesign in 35 years of the world’s most ubiquitous font, Helvetica
Consisting of 48 fonts and three optical sizes, the typeface has been produced from size-specific drawings and with size-specific spacing and is the first redesign in 35 years of what many argue is the world’s most ubiquitous font, Helvetica. Every character has been redrawn and refit, and a host of useful alternates have been added to help brands meet modern-day branding challenges.
Accessibility Before Aesthetics
It’s time we start addressing accessibility before aesthetics in our design processes to create meaningful products for our diversified societies and cultures. Before diving into the why, how and what of it, let’s revisit the definitions of these terms to set the context.
The lifecycle of a redesign: Making Reddit more welcoming
“We could’ve taken the approach of the designer as a magician—‘Ta-da! Here it is!’” says Zavani. “But we’ve seen other site re-designs that are so extravagant or so far from reality that they never actually become a reality. At the end of the day, we wanted to make sure that people use Reddit the way they’ve always used Reddit, because it’s a magical, weird, and wonderful place.”

Secrets to a Successful Designer 🤝 Developer Handoff
Let’s be honest, getting designs from your UX team into the hands of your engineering team in a way that makes sense is rarely easy. Add tight deadlines, team changes, and miscommunication to this process and your application will likely end up looking very different than what you expected. The handoff between design and development is no easy task.

How we think about product at Gatsby
As a company grows, it will eventually start offering products or services to the community it’s trying to serve. It’s an exciting time filled with near constant changes. At Gatsby, we realized that this meant we needed to have a better understanding and core philosophy around the products we create.
Slack Is Not Where ‘Deep Work’ Happens
How did you start your day today? Probably reached for the phone. Turned off the alarm. Glanced at the time. Scrolled through the Slack notifications. Went through the emails. You will likely continue doing it throughout the day, approximately 2,617 more times, according to some studies. We all do it, and despite all the virtues of digital minimalism, completely giving up those habits is extreme and, arguably, unnecessary. Yet we live in a culture obsessed with productivity and these harmless distractions are wreaking havoc on it.
听编程猫 CTO 孙悦讲教育科技公司如何用编程影响社会未来
在1998年亚马逊致股东信里，贝佐斯说：“我们要反抗熵（We want to fight entropy）。”管理学大师彼得·德鲁克说：“管理要做的只有一件事情，就是如何对抗熵增。在这个过程中，企业的生命力才会增加，而不是默默走向死亡。”物理学家薛定谔说：“自然万物都趋向从有序到无序，即熵值增加。而生命需要通过不断抵消其生活中产生的正熵，使自己维持在一个稳定而低的熵水平上。生命以负熵为生。”这么多人都在谈论熵，说要反抗熵，然而到底什么是熵？
