In the Spotlight 🔦

GitHub outage

GitHub had a major outage on August 17, that lasted over 7 hours. They have published a postmortem on the outage. Outside the neither here nor there messaging in the postmortem, there are some graphs that show the scale that AI agents have caused on GitHub and coding in general.

We failed to scale critical components before demand exceeded their capacity.

The outage prompted all of GitHub's stealth competitors to emerge and announce their products while it was still ongoing.

• Cursor Origin
• code.storage from Pierre Computer Company
• Cloudflare Artifacts
• Netlify Source
• Zed DeltaDB - More of keeping the conversations along with code.

The Cursor team wrote about how they arrived at a backend architectural solution for their product Origin: Git at scale. It's a well structured write up on the shortcomings of GitHub architecture to deal with agent traffic and how Cursor wants to get ahead by using S3 write ahead logs. Tobi Lutke was inspired by the article to code his own solution for a git monorepo - walgit

OpenAI hacking Huggingface

The incident with OpenAI hacking Huggingface became a public spectacle and caught the eye of people who are not into tech in general. Here's some must reads from the incident:

• The Hugging Face incident and the road ahead - OpenAI blog
• Anatomy of a Frontier Lab Agent Intrusion - Hugging face
• Anthropic's incident report on Claude models
• OpenAI researcher presentation at BlackHat USA available for streaming on YouTube
• AI assistant hacks gym website in first known Australian autonomous cyber attack - ABC News
• The incident has even got Bill Gates to change his mind on AI

Security

• Next.js August security release
• Wordpress pre-auth XSS CVE
• Mini Shai-Hulud npm supply chain attacks from August hit 440+ npm packages - ChainDrop supply chain compromise: Anatomy of a self-propagating worm - Microsoft
• LiteLLM hack and 153GB of data publicly available on the Internet.
• Vercel raises the alarm with Everything hackable will get hacked

How we migrated lovable.dev away from Next.js and turned it into another Lovable app

Lovable moved the app, developing it in parallel, from Next.js to Tanstack Start. The article shares tidbits about the workarounds they used and how they handled the challenging navigation between the frameworks during the migration.

Styling Linear for the future with StyleX

Linear migrated their codebase from Styled Components to StyleX. The blog explains why they chose this migration and why StyleX was the ideal choice. Moreover, it shows how developer tooling streamlined the migration.

Cursor also has a post on migrating their interface from Solid to React and SCSS, Tailwind to StyleX.

Creator of TypeScript: 10x Faster Typescript, Why AI Won't Replace SWEs | Anders Hejlsberg - YouTube

Anders Hejlsberg, creator of TypeScript, C#, and Turbo Pascal, explains why he chose JavaScript as the language to start TypeScript and why he later migrated it to Go. He describes how LLMs facilitated the large, mostly error‑free migration, while human insight remained valuable in many cases.

Async Solid - Fetch High, Block Low - Ryan Carniato

As Solid 2.0 release is close, Ryan Carniato talks about how async is implemented in SolidJS through a series of blog posts. You should give it a read on how async gets implemented today vs how it could be simplified. This is my favourite aspect of the lot.

There is no special primitive. No loading flag. No story()?.title. story() is a Story, not a Story | undefined. The types reflect what you see. If it is running, it is there.

In Other News

New M6 Mac Mini

Apple skipped the ceremony and announced the new devices last week through a blog post and a YouTube video. Apple highlights the new processor family and its 4x improvement in AI performance, but the devices also cost $100 more than the previous versions.

On a developer note, Apple has asked developers to remove Intel processor support for smaller size and efficiency.

There's a also a new Framework 12 in town.

Jeff Dean: The 1% Rule for Building in AI | YCombinator - YouTube

There's always time in my life for listening to a Jeff Dean interview, even if it's just to marvel at the technical genius that he is. He's asked a lot of questions that he had not prepared the answers for, so some of the agent use cases turn out to be the obvious, but it's a good take for the napkin math. Also this month, Jeff Dean and Sanjay Ghemawat left Google to start their own AI company named Discovery Loop

Mathematicians and AI

The first field AI took by storm was software development. It has likely changed every way software is written. The next field that every AI lab is focusing on is mathematics, because it is even more independently verifiable than software. How should a mathematician react to this sudden change in their field?

• Mathematicians are grappling with the possibility that AI might eclipse them
• Mathematics in the age of AI
• The End of Mathematics

Also an idea, Software engineers will become scientists
