Senior Backend Interview Question:
Two engineers built pagination for 100 million users.
Engineer A 👇
GET /posts?page=4&limit=10
Engineer B 👇
GET /posts?cursor=eyJpZCI6NDB9&limit=10
Both work perfectly at 1,000 users.
At 100 million users, one of them makes your database cry.
Which one would you approve — and why?
Excited to share that MagicPath is now available as an official plugin for Codex, in collaboration with OpenAI!
It's incredibly easy to give Codex an infinite multiplayer canvas where it can design, build, and iterate with you.
AI agent 要跑沙箱隔离,但冷启动微VM太慢了。这个项目干脆把预热好的父 VM snapshot 当进程 fork:子 VM 共享内存直到写时才复制,100 个 KVM 隔离的沙箱 100ms 就能全出来。相当于把 fork 的开销套在 VM 身上,还保留了硬件隔离,思路挺离谱的。

Karpathy found a way to reduce token consumption by 90%
The problem is that the LLM re-reads the same files over and over again, loses context between documents, and provides less accurate answers as a result
The solution is called Wiki Layer the LLM cleans, structures, and links all your data once, after which it never works with raw files again
Three folders `raw/` for originals, `wiki/` for a clean knowledge base in Markdown, and files with rules for the agent
Result up to 90% token savings on repeat queries, automatic links between documents, and a visual knowledge graph in Obsidian

jina-embeddings-v5-omni is here! Our first universal embedding model for text, images, audio, and video. Available in two sizes: small (1.57B, 1024-dim, 32K context) and nano (0.95B, 768-dim, 8K context). Both support Matryoshka truncation down to 32 dimensions.
v5-omni is back-compatible: if you already use jina-embeddings-v5-text-small/nano, the existing text indexes work with v5-omni out of the box. Without reindexing the text, just index your multimodal content with v5-omni and start searching images, audio, and video.
