This Week’s Hot Topics

The ECMAScript 2023 Language Specification https://tc39.es/ecma262/
This Ecma Standard defines the ECMAScript 2023 Language. It is the fourteenth edition of the ECMAScript Language Specification. Since the first edition was published in 1997, ECMAScript has grown to become one of the world’s most widely used general‑purpose programming languages. It is best known as the language embedded in web browsers but has also been widely adopted for server‑side and embedded applications.

Let’s see how to achieve phenomenal web performance and a great developer experience with Astro and a headless CMS, resulting in the best possible experience for users, developers, and content creators alike.

Planning for AGI and beyond https://openai.com/blog/planning-for-agi-and-beyond/
Our mission is to ensure that artificial general intelligence—AI systems that are generally smarter than humans—benefits all of humanity. If AGI is successfully created, this technology could help us elevate humanity by increasing abundance, turbocharging the global economy, and aiding in the discovery of new scientific knowledge that pushes the limits of possibility.

Since declaring our intention to leave the cloud in October, we’ve been busy making it happen. After a brief detour down a blind alley with an enterprise Kubernetes provider, we found our stride building our own tools and successfully moved the first small application out of the cloud a few weeks ago.

How Meta brought AV1 to Reels https://engineering.fb.com/2023/02/21/video-engineering/av1-codec-facebook-instagram-reels/
Over the past few years, Meta has worked closely with the open‑source community to optimize AV1 encoder and decoder implementations for real‑world, global‑scale deployment. Our goal is to improve playback beyond what we currently offer with AVC and VP9, ensuring that as we roll out AV1 it delivers real value to the people who use our apps.

The Missing Semester of Your CS Education https://missing.csail.mit.edu/
Classes teach you advanced CS topics—from operating systems to machine learning—but there’s one critical subject that’s rarely covered and is left for students to figure out on their own: proficiency with their tools. We’ll teach you how to master the command line, use a powerful text editor, leverage advanced version‑control features, and much more!

The age of cargo‑cult Agile must end https://jchyip.medium.com/the-age-of-cargo-cult-agile-must-end-9408e1d13e1d https://uxdesign.cc/the-age-of-agile-must-end-bc89c0f084b7
At first, I thought “The age of Agile must end” was an example of the cargo‑cult reinvention cycle, but looking more closely it seems both a cargo‑cult misunderstanding of Agile and an argument for something not aligned with Agile. I don’t necessarily think this was an intentional straw‑man argument, though.

The Jungle Doorbell: A Business Model That Maximizes “Luck” https://mp.weixin.qq.com/s/BWjDxLA8V_M_wlfnZCGc4Q
Most managers rely on numbers to make decisions. The more detailed the data, the more reliable their models, the higher the success rate of decisions, and the more resources they can mobilize. This vertical, data‑driven thinking feels concrete and justifiable—“procedural justice”—so even failure is understandable. It rarely yields huge returns, but passing is easy. The “jungle doorbell” described in the article is a horizontal thinking method. It abandons specific, pre‑planned ideas and focuses on reacting to the process. Horizontal thinking may seem loose and unserious, appearing like luck, but it can continuously increase the “surface area” of luck (e.g., by cheaply placing many more doorbells).
