Building Angular and React Applications Together With Nx https://blog.nrwl.io/building-angular-and-react-applications-together-with-nx-78b5578de598 Large companies often use multiple frontend frameworks to build their products. One product can be built with Angular, another one with React. These products, even though are built by different teams using different stacks, often share components and utilities. Setting this up traditionally is challenging. Companies put a lot of effort in making sure teams can collaborate and use each other’s work. Nx drastically simplifies this.

Flutter’s Key Difference: Owning Every Pixel https://medium.com/flutter-community/flutters-key-difference-owning-every-pixel-e2135b44c8a There’s been plenty of comparing Flutter with other cross-platform mobile frameworks. But the key difference is often overlooked or downplayed. Flutter owns every pixel on the screen.

Why you shouldn’t use Moment.js… https://inventi.studio/en/blog/why-you-shouldnt-use-moment-js JavaScript’s built-in Date object is far from ideal, let’s admit it. We could spend a lot of time talking about Date API methods like getYear, however we believe everything has been told in that matter. Everyone of us, at some point realized that or has been warned by older friends, if lucky enough. Whatever the reason was, at the end we all reached for external library and the choice was obvious - Moment.js. The most popular JS DateTime library that gave us everything we wanted so much from native Date API.

Give Me Back My Monolith http://www.craigkerstiens.com/2019/03/13/give-me-back-my-monolith/ It feels like we’re starting to pass the peak of the hype cycle of microservices. It’s no longer multiple times a week we now see a blog post of “How I migrated my monolith to 150 services”. Now I often hear a bit more of the counter: “I don’t hate my monolith, I just care that things stay performant”. We’ve actually seen some migrations from micro-services back to a monolith. When you go from one large application to multiple smaller services there are a number of new things you have to tackle, here is a rundown of all the things that were simple that you now get to re-visit.

Visualizing Cold Starts https://mikhail.io/2019/03/visualizing-cold-starts/ I wrote a lot about cold starts of serverless functions.

Amazon Aurora ascendant: How we designed a cloud-native relational database https://www.allthingsdistributed.com/2019/03/Amazon-Aurora-design-cloud-native-relational-database.html Aurora’s design preserves the core transactional consistency strengths of relational databases. It innovates at the storage layer to create a database built for the cloud that can support modern workloads without sacrificing performance. Customers love this because Aurora provides the performance and availability of commercial grade databases at 1/10th the cost. Since Aurora’s original release, it has been the fastest-growing service in the history of AWS. In this post, I’d like to give you a peek under the hood at how we built Aurora. I’ll also discuss why customers are adopting it faster than any other service in AWS history.

Iodide: an experimental tool for scientific communication and exploration on the web https://hacks.mozilla.org/2019/03/iodide-an-experimental-tool-for-scientific-communicatiodide-for-scientific-communication-exploration-on-the-web/ In the last 10 years, there has been an explosion of interest in “scientific computing” and “data science”: that is, the application of computation to answer questions and analyze data in the natural and social sciences. To address these needs, we’ve seen a renaissance in programming languages, tools, and techniques that help scientists and researchers explore and understand data and scientific concepts, and to communicate their findings. But to date, very few tools have focused on helping scientists gain unfiltered access to the full communication potential of modern web browsers. So today we’re excited to introduce Iodide, an experimental tool meant to help scientists write beautiful interactive documents using web technologies, all within an iterative workflow that will be familiar to many scientists. 另附:Introducing Firefox Send.

I’d like to thank everyone involved in that effort, including Let’s Encrypt staff and other IETF contributors.

Sucrase https://github.com/alangpierce/sucrase Sucrase is an alternative to Babel that allows super-fast development builds. Instead of compiling a large range of JS features to be able to work in Internet Explorer, Sucrase assumes that you’re developing with a recent browser or recent Node.js version, so it focuses on compiling non-standard language extensions: JSX, TypeScript, and Flow. Sucrase is about 20x faster than Babel.

XXH3 - a new speed-optimized hash algorithm https://fastcompression.blogspot.com/2019/03/presenting-xxh3.html The xxHash family of hash functions has proven more successful than anticipated. Initially designed as a checksum companion for LZ4, it has found its way into many more projects, requiring vastly different workloads. I was recently summoned to investigate performance for a bloom filter implementation, requiring to generate quickly 64 pseudo-random bits from small inputs of variable length. The end result of this investigation is XXH3, a cross-over inspired by many other great hash algorithms, which proves substantially faster than existing variants of xxHash, across basically all dimensions.

ArchiveBox https://michael.stapelberg.ch The open-source self-hosted web archive. ArchiveBox takes a list of website URLs you want to archive, and creates a local, static, browsable HTML clone of the content from those websites (it saves HTML, JS, media files, PDFs, images and more).

开源时代,人才哪里找?这份报告给出了一份详尽的人才供需图 https://zhuanlan.zhihu.com/p/59381112 伴随着供给侧改革的逐步深化,2019年将是企业人才生态进化与经济结构性改革的冲刺年。这场赛跑,既是对企业“节流”能力的检验,也是对企业“开源”能力的挑战。“节流”体现在企业如何通过建立科学的培训和晋升机制,快速提升内部人才资本的生产效率;“开源”则体现了企业如何不断提升自身吸引力,最大化地建立起与外部人才生态的互联网络。与此同时,我们每个人在面临时代变革的时候如何固本培元,在把握就业市场脉搏的同时应该重点增强那些方面的竞争力,BOSS直聘《开源时代:2019年人才资本趋势报告》尝试给出答案。本报告按照从宏观到微观的视角,对当下就业市场的九个趋势进行了深度分析,试图为读者展示一张未来就业市场的导航图。笔者对报告重点进行了梳理,以飨读者。

张一鸣谈「务实的浪漫」:把想象变成现实 https://www.geekpark.net/news/239089 张一鸣在公司 7 周年庆典上首次提到,字节跳动是一家务实浪漫的公司。所谓务实浪漫,就是把想象变成现实,face reality and change it。体现在产品上,有同理心是务实,有想象力是浪漫。「同理心是地基,想象力是天空,中间是逻辑和工具。」A/B 测试只是工具,测不出用户需求,同理心才是重要的基础。但是光有同理心还不够,这样只能做出有用的产品。想要做出彩的产品,想象力非常重要。
