这家半年内市值腰斩的电商巨头,核心风险究竟是什么?
With 120 methods listed, this is the most complete list of prioritization frameworks on the internet with tons of linked resources.
A way to structure the logical approach to product discovery & reduce the likelihood of product failure.
卡耐基在《人性的弱点》一书中说:“世界上唯一能影响他人的方法,就是谈论他所要的,而且还要告诉他,如何才能得到他所要的”。由此可见,良好的沟通交流可以很大程度上拉近双方的关系,进而影响对方。闲鱼消息是买家了解二手物品信息不可或缺的一环,我们有理由推断良好的聊天能够对成交产生正向影响。推断需要数据来佐证,通过对以往聊天成交数据的关联分析,我们得到了如下结论:
我们推测个人卖家转化率偏低的一个原因是不会好好聊天,通过抽样case发现部分卖家回复内容高冷、生硬、情绪化,进而导致双方尴尬,聊天戛然而止。所以我们探索的方向就是如何引导卖家与买家好好聊天,通过算法意图识别,以聊天小助手的形式给卖家提供友好的建议性话术,让沟通交流不再僵硬。
Next.js 提供了生产环境所需的所有功能以及最佳实践,包括构建时预渲染、服务端渲染、路由预加载、智能打包、零配置等。本文将介绍 Next.js 提供的三种预渲染模式以及混合渲染模式,来看看 Next.js 是怎么做预渲染的。
在我们采集数据时,有些数据可以直接通过爬虫来获取,但有些数据出现在PDF,Excel,Word等文档中时,爬虫实现就有局限性了,我们必须编写很多自定义函数用来解析文档,并且脚本代码一多,就失去了可维护性和使用爬虫编写业务逻辑的初衷。所以我们需要建设一套解析流水线来实现提取文档数据的需求。甚至需要从PDF影印版中提取数据,总体需求简述:
For a company of our size and scale, robust, accurate, and compliant accounting and analytics are a necessity, ensuring accurate and granular visibility into our financials, across multiple lines of business.
Most standard, off-the-shelf finance engineering solutions cannot support the scale and scope of the transactions on our ever-growing platform. The ride-sharing business alone has over 4 billion trips per year worldwide, which translates to more than 40 billion journal entries (financial microtransactions). Each of these entries has to be produced in accordance with Generally Accepted Accounting Principles (GAAP), and managed in an idempotent, consistent, accurate, and reproducible manner.
To meet these specific requirements, we built an in-house Uber’s Finance Computation Platform (FCP) —a solution designed to accommodate our scale, while providing strong guarantees on accuracy and explainability. The same solution also serves in obtaining insights on business operations.
There were many challenges in building our financial computation platform, from our architectural choices to the types of controls for accuracy and explainability.
One of our biggest priorities at Pinterest is keeping Pinners safe, and that includes protecting them from spam. The Trust & Safety team’s goal is not only to catch spam, but to remove it as quickly as possible to minimize Pinner impact.
The goal of spammers is to make money, and the best way to do this is to spam at scale. It’s a numbers game: one million spam emails are much more effective than one spam email. In order to remove spam quickly, we look at common trends in spam attacks to identify suspect behavior.
To achieve the scale required to be effective, spammers must automate their actions, and each of these “attacks” can be thought of as a cluster. Each event within the attack cluster may share some common features, but different clusters will have a different set of common features.
For example, during an attack where a large number of Pins are created, a spammer might point all Pins to the same domain. While the domain may change between attacks, spammers are still trying to direct traffic to the same spam site.
One of our spam mitigation tactics is our rule engine, Guardian, which helps to identify common features in spam attacks.
DRM technology for streaming media is a decades-long evolution of cold war era communication techniques. Here’s how Vimeo does it.
一般在我们工作中,主要会涉及到 9 种文件下载的场景,每一种场景背后都使用不同的技术,其中也有很多细节需要我们额外注意。
我们知道技术的本质是将 idea 落地,技术面向的用户一般是开发者,而低代码或者零代码其实也是一种技术手段,但低代码面向的用户则不一定是开发者,它的目标用户是想要实现 idea 的任何人,低代码是实现 Citizen Developer(全民开发者) 的关键。低代码通过抽象和交互升级隐藏了很多技术细节,抹平了开发者和非开发者的知识差异,让非开发者也能亲手实现自己的 idea,这就是赋能,因此低代码的本质其实是跨专业能力的赋能。
FAE主要聚焦于用户行为分析和广告归因分析。在这些场景上,FAE的计算性能能够达到通用的OLAP引擎的一到两个数量级。
随着社会发展进入数字经济与实体经济融合发展的关键时期,人工智能正日益成为驱动产业转型发展的核心引擎。近年来,在人工智能相关政策和先进技术的双重推动下,各大企业及资本纷纷加大布局人工智能产业的力度,使得AI领域的人才需求井喷,而AI人才的培育相对滞后。
本文就来聊一聊一件逼真的3D服装是如何渲染到用户界面上的,3D服装渲染的应用又能给我们带来什么?
找 bug 的方式都不是很高效,导致最终 bug 找不到或者走了很多弯路。
流量平台已经覆盖了 2000 多个应用,管理埋点(事件)数 20 万,每天产生的埋点数据量超过万亿。
最近看到 自如团队 发布的 自如客APP裸眼3D效果的实现,这个布局确实做得很有趣,越玩越上瘾,感谢自如团队的分享。随即按照自己的思路用 Flutter 实现一遍,来看看最终效果。
近年来 AI+Test 相关的智能化测试技术,已经逐步成为国内·国际大型互联网公司和各大测试服务提供商的基础能力。其智能化包含测试代码的自动生成、大规模测试结果分析、自动化探索性测试、缺陷定位及修复等。相关公司、产品或服务比较有代表性的有:Test.AI、Applitool、Totoro、Eggplant、Appdiff 等。

现代高级编程语言管理内存的方式分自动和手动两种。手动管理内存的典型代表是C和C++,编写代码过程中需要主动申请或者释放内存;而PHP、Java 和Go等语言使用自动的内存管理系统,由内存分配器和垃圾收集器来代为分配和回收内存,其中垃圾收集器就是我们常说的GC。本文中,腾讯后台开发工程师汪汇从原理出发,介绍 Java 和Golang垃圾回收算法,并从原理上对他们做一个对比。今天先向大家分享 Java 垃圾回收算法。
