Gartner在上月底发布了中国低代码平台市场竞争格局报告。这是Gartner针对中国市场为数不多的Competitive Landscape报告之一，足以显示这个细分市场当下和未来的重要性。

如何让设计推理更严谨？

自从苹果公司在国内推出ABM应用分发平台后，苹果公司不再接受toB应用在App Store平台上分发。由此，物流工程师们总结了一个完整的ABM分发方案，尽可能减少用ABM平台分发给用户带来的不便。

Getting a Vue app to perform faster and smoother is one of the issues Vue.js software developers face. One way to do that is by offloading some heavy-duty work to another thread and allowing the main thread to handle the UI. But we can only do that with the help of web workers.

In this article, we will talk about web workers, how to offload a task to a web worker and how to optimize our web application by hooking a web worker into it and the app workflow.

Why don't we hear more developer voices in the conversation about "developer productivity"? Most self-styled experts on developer productivity seem more interested in selling something rather than painting an accurate picture of how devs really work. Perhaps as a consequence, we're swimming in acronyms, magic metrics, and methodologies, but not a lot of rigorous systems thinking.

技术决策需要在不同限制条件下做出权衡，本文介绍了Twitter早期应对用户大规模增长所做出的技术架构决策。

Machine Learning models at Lyft make millions of high stakes decisions per day from physical safety classification to fraud detection to real-time price optimization. Since these ML model based actions impact the real world experiences of our riders and drivers as well as Lyft’s top and bottom line, it is critical to prevent models from degrading in performance and alert on malfunctions.

However, identifying and preventing model problems is hard. Unlike problems in deterministic systems whose errors are easier to spot, models’ performance tends to gradually decrease, which is more difficult to detect.

Node.js exposes many features of the filesystem. But not all filesystems are alike. The following are suggested best practices to keep your code simple and safe when working with different filesystems.

In recent years, the web has gotten very hostile to the lowly web scraper. It's a result of the natural progression of web technologies away from statically rendered pages to dynamic apps built with frameworks like React and CSS-in-JS. Developers no longer need to label their data with class-names or ids - it's only a courtesy to screen readers now.

There's also been a concerted effort by large companies to protect their public data. Facebook, for example, employs a team of over 100 people to make sure it is as difficult as possible for any data to escape the black hole. Granted, some of these large companies do offer APIs for their data but rarely is this unrestricted. You're usually at the whim of their app review process or granted access only to a partial view of the data. Data that would be otherwise public if you were to do a Google search and click through to their website manually.

This can be frustrating if you're like me - somebody who wanted to build a small, local, non-profit app that uses data hosted on a closed platform. The data is public but completely inaccessible to machines because of aggressive anti-web-scraping measures. That gave me two options - input the data manually or play the web-scraping game. Of course, I chose the latter.

AST Babel 入门手册，手把手带你还原 JS 混淆代码，让你逆向如虎添翼！

本文主要讲解了，出行平台的来源，系统构建时的思考，以及在设计时遇到的问题。

zookeeper是一个比较成熟的，经过市场验证的分布式协调框架，可以协助我们快速的解决分布式系统中遇到的一些难题。另从上面的介绍中发现，zookeeper的核心是zab，etcd的核心是raft，那可以思考下，还有哪些一致性算法？

最终回归数学题的​path，如何画好辅助线是一个很有效加大开发效率的好方式。

在过去的一段时间内，京东Android APP通过图片压缩、图片转下载、资源混淆编译、插件化、插件后装、混合开发等一系列手段对安装包大小进行了优化，取得了不错的瘦身收益。在完成这些常规瘦身手段优化后，为了进一步优化安装包的大小，调研了谷歌官方新推出的 R8 编译器，了解到R8编译器在提升构建效率的同时，又能优化包体积大小，所以我们开始尝试升级AGP版本来启用R8编译，升级的过程不是很顺利，遇到了下面这些问题。

演绎（Deductive reasoning）、归纳（Inductive reasoning）与反演（Abductive reasoning，诱因推理、溯因推理）是科学研究甚至日常工作中的重要逻辑思维。本文分享两篇不同读者对象的文章，来看看人们是如何从不同角度介绍这几个基本概念的。第一篇发表在大众读物上，写得更科普些。第二篇是学院级别的介绍，写得更专业些。

生活中我们更多的是作为被服务者的角色，比如在餐厅等了几个小时饭菜还没做好、抢票时遭遇系统崩溃错失购买机会等，我们几乎都投诉过，换位思考，我们清晰地了解投诉客户心理状态。愤怒、着急、焦虑，这些负面的情绪往往围绕着客户。

企业在前期通过各种方式积累的用户好感，也有可能在一通处理不当的投诉下灰飞烟灭。但投诉并非无解，即使做得再好的产品和服务，也会有问题的情况。如果我们能合适的处理好故障，帮助商家解决问题，反而能变坏为好。

早期我们并不鼓励任何的开发或者技术支持直接对接商家，在没有足够的客户服务和风险意识的情况下，直接对接往往会带来更多的问题。后来，在有赞上经营的大商家越来越多，服务和体验要求越来越高。我们也逐渐开放，让一部分懂服务懂商家的同学，直接对接，帮助商家解决问题，缓解商家焦虑的情绪。

面对同一场危机，为什么有的企业能逆势反弹，而有的企业则轰然崩塌？其实，所有企业都会遭遇逆境，能否突围和持续成功，就在于企业领导者是否具有作为攀登者的底色——选择迎难而上并持续成长的能力。

那些在危机中存活下来，甚至从顶峰跌落至低谷再触底反弹的企业，其领导者都具备一个共同特点——将逆境转化为机遇和竞争优势的能力，也就是所谓的高「逆商」。

网上有不少文章探讨站会的目的、形式和技巧。然而，读了那么多文章，依然开不好站会。今天，我尝试从团队的角度来分析站会在不同阶段的价值，以及为了获得这种价值我们要如何做。

初学者的套路就是模仿。他们面临的障碍是：（1）模仿照着来，也做了好几个表格（包括基准回归结果等），却感觉不知道要说什么，没办法，只能光秃秃地放几个表格在那里，显得很突兀。这种情况可以用“无话可说”来概括。（2）仍是模仿，也能做到该有的都有，既有文字也有图表，但总是感觉写的很平淡，没有重点和线索，也缺乏层次。这种情况可以用“有话说不好”来概括。

之所以会出现上述两种情况，原因就是没有理解和把握好“实证分析”及“实证论文”。

“华为的人才是多元化的”，华为的领导层是这么说，也是这么做的，华为的人才结构就是按照这些思想去架设和实施的。

企业中需要高层次人才吗？适合本企业的人才结构是什么样的？我们企业适合金字塔型吗？椭圆型？还是梯型？

真正要通过税收分配来实现共同富裕唯一的办法就是要加大对高收入人群的征税力度，让国家对高收入人群的名义税率变成实际税收收入。
