Today, I'm launching llmdojo.dev:
- The hands-on way to learn AI engineering: LLMs, RAG, agents, evals and inference.
- 50+ interactive labs. Tweak tokenizers, attention, embeddings and KV caches live.
- Train a neural network in your browser and watch it learn.
- Build agentic workflows with tool calls, memory, guardrails and bounded autonomy.
- Ship RAG that works: chunking, hybrid search, reranking, and LLM-as-a-judge evals.
- Production AI: model routing, fallbacks, quantization, caching and cost per request.
- 490+ interview questions, reported from OpenAI, Anthropic, Google, Meta, Amazon, Microsoft, Mistral and 50+ more.
- Every answer is cited from papers and books, or measured on real models.
that's true, use mdxcn.dev to make your markdowns richer

Introducing DataBull 🎉
I was paying $39/mo for DataFast just to see which posts made me money.
That's $468 a year. Forever. And it goes up as your traffic grows.
So I built my own.
Same idea: revenue by traffic source.
$29 lifetime. Unlimited sites. Unlimited events. Lifetime updates.

Introducing Ardia, the open-source Arc
I've been working on this for a few months now. It's feature-complete, already used by a bunch of former Arc users, and extremely performant.
github.com/mantrakp04/ardia
We've decided to sunset Arc on December 22, 2026.
That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.
Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.
We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:
· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.
Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.
prime time to switch to @heliumbrowser

this has shaped up to be a really cool app and here's all that's coming 👇🏻
- browse and install skills directly from skills.sh in just one click
- see live agent sessions, MCP servers, and dev servers, and stop the ones you’re done with
- free up context and disk space from unused skills, old session history, and leftover testing builds
- one CLAUDE.md, command, or MCP server, linked across every agent
