Responsible JavaScript: Part I
https://alistapart.com/article/responsible-javascript-part-1
By the numbers, JavaScript is a performance liability. If the trend persists, the median page will be shipping at least 400 KB of it before too long, and that’s merely what’s transferred. Like other text-based resources, JavaScript is almost always served compressed—but that might be the only thing we’re getting consistently right in its delivery.

Blazingly fast parsing, part 1: optimizing the scanner
https://v8.dev/blog/scanner
To run a JavaScript program, the source text needs to be processed so V8 can understand it. V8 starts out by parsing the source into an abstract syntax tree (AST), a set of objects that represent the program structure. That AST gets compiled to bytecode by Ignition. The performance of these parse + compile phases is important: V8 cannot run code before compilation is done. In this series of blog posts, we focus on parsing, and the work done in V8 to ship a blazingly fast parser.

近年来,开源技术得到越来越多的重视,微软收购 GitHub、IBM 收购红帽,都表明了开源的价值。国内公司也越来越多的参与开源,加入开源基金会 / 贡献开源项目。但是,它们到底做得如何呢?为此 InfoQ 统计了国内在 GitHub 上较活跃的 7 家一线互联网公司的 50 多个账号的 2800 多个项目,为大家呈现一部分答案。

计算广告系统算法与架构综述
https://mp.weixin.qq.com/s?__biz=MjM5ODkzMzMwMQ==&mid=2650409451&idx=1&sn=38c225b5d084558a09240ba2cffd0570
我们当今身处一个被广告包围的时代,无论是走在马路上、收看电视剧、或者是玩手机游戏,都能看见形形色色的广告。作为IT从业者,自然想对广告产业背后的产品、技术一探究竟,正如刘鹏博士在其《计算广告》一书中所说的“不论你在做一款用户产品还是商业产品,不深入了解在线 广告,就不太可能全面地了解互联网业务”,因此本文也希望能带领读者从产品、技术以及整个生态的角度深入浅出的了解计算广告。

配置化页面渲染系统设计和实践
https://mp.weixin.qq.com/s/nwC7-ATCCUBS11Gb7FtbgA
随着大数据、监控系统、分析系统等概念逐渐在各大小公司中普及后,开发一个前端系统以展示和控制的需求则变得十分常见,所以我们也不例外。在开始着手开发之前,事实上我们已经考察甚至长时间使用过一些不同类型的类似系统,如监控报表系统 Grafana、数据分析系统 Zeppline、Metabase、Superset 等等。我们不难发现这些的设计思路都有一个共同的特点:卡片式页面结构。

Was MongoDB Ever the Right Choice?
https://www.simplethread.com/was-mongodb-ever-the-right-choice/
MongoDB has become a much more mature product. So what happened? Did all of the hate truly come from mistakes made in the early implementation/marketing of MongoDB? Or is the problem that people are blaming MongoDB for their own lack of efforts when evaluating if it was a good fit?

How Heroku Expects the Unexpectable
https://blog.heroku.com/bug-bounties-black-swans
There’s obviously more to security than humans, technology, and vendors with all of their implementations and expertise. At Heroku we believe that security is a byproduct of excellence in engineering. All too often, software is written solely with the happy path in mind, and security assurances of that software has it’s own dangerous assumptions. A mature security program should challenge assumptions of security controls, move to testing continuous, and prepare for the unexpectable.

Sonic
https://github.com/valeriansaliou/sonic
Sonic is a fast, lightweight and schema-less search backend. It ingests search texts and identifier tuples that can then be queried against in a microsecond’s time. Sonic can be used as a simple alternative to super-heavy and full-featured search backends such as Elasticsearch in some use-cases. It is capable of normalizing natural language search queries, auto-completing a search query and providing the most relevant results for a query. Sonic is an identifier index, rather than a document index; when queried, it returns IDs that can then be used to refer to the matched documents in an external database.
