New in Crush today: Jobs! Crush can now run and manage background processes. Spin up a dozen Xcode builds, start a swarm of Docker containers, and go crazy. The asynchronous world is now at your (LLM’s) fingertips.
DSPy Signatures anchor your app in a world where everything changes—prompting techniques, model families, even serialization formats. vicentereig.github.io/dspy.r… Pair TOON with @boundaryML's BAML and BOOM! Drop tokens in half.

Turn any GitHub repository into rich, navigable docs. Simply replace "github" with "deepwiki" in the repo URL.

B‑trees face issues like page splits, locks, and buffer pins. LSM‑trees avoid them but raise write amplification. WiredTiger takes a third path: lock‑free B‑trees with hazard pointers for reads and skip lists for writes. Great article on the @MongoDB blog: mongodb.com/company/blog/eng…

day 99/100 of GPU Programming - real ones know this is day 100 cause I started at day 0 like a real programmer - practiced writing a 2D conv kernel in CUDA
day 98/100 of GPU Programming - practiced writing an FP16 Dot Product kernel in CUDA

And if you need something that works with any coding agent with access to Bash, here you go: mariozechner.at/posts/2025-1…
one of the best ways to make Claude Code a general agent- browserbase's plugin makes it so Claude can actually use your browser (with your cookies) and take actions using language

We keep saying "AI makes shipping things faster". But what really happens is that it also makes skipping steps easier. Not necessarily in a good way. If you build with AI, this is a must-read essay by @kieranklaassen on how to stop coding without planning things first. Teach AI how you think and it will get smarter with every feature you build. every.to/source-code/stop-co…

Claude Code just added a new environment variable yesterday 😨 CLAUDE_CODE_EXIT_AFTER_STOP_DELAY - auto-exits SDK mode after idle duration. Useful for CI/CD and automated workflows. Wrote up a complete reference covering all 40+ variables (auth, models, performance, cloud integration) Link: medium.com/@dan.avila7/claud…
Running Claude Code isn’t just about opening the terminal and typing the perfect prompt. (Bookmark this post for later) There are environment variables that can influence how Claude Code runs, connects to models, and even how its interface behaves. 🧵 Here’s a thread with all of them organized by category:

Learn MLOps by implementing this pipeline. This is a great repo which covers every stage of the pipeline, introducing you to some essential principles. This can be covered in 10 weeks. You learn > Project setup, Model Monitoring > Configuration Management > Data Version Control > Model packaging and deployment > Prediction Monitoring Along the way, learn the base toolset needed to setup an MLOps pipeline.

This aligns perfectly with what Anthropic just published about code execution with MCP Link: anthropic.com/engineering/co… In Claude Code, I've noticed Claude prefers writing and executing code directly in bash rather than using tool calls. I've seen Python scripts appear, execute, and disappear in a single run, Claude knows it needs to minimize token usage and work as efficiently as possible.
Lately I’ve been testing both CLI and MCP in Claude Code... and honestly, the CLI wins I list all my installed tools (vercel, supabase, gh, etc.) in CLAUDE .md and let Claude use them to check logs, run queries, or tweak configs. Setup is simpler, auth is native, and observability is crystal clear. There’s still debate on CLI vs MCP, but in my workflow, CLI is miles ahead

An interesting article on Substrate from Fox Chapel Research. Summary: The founder is a known con artist involved in such other things as solving nuclear fusion and stealing $2.5M in a Kickstarter scam. The cofounder is the founder’s brother and has literally zero documented professional or academic experience. The company’s job postings are nonsensical and AI-generated. The company is unwilling to evidence any of its (extremely extraordinary) claims, which have been made on a timescale that makes no sense in the context of the semiconductor industry. The company’s research facility is, based on photographs that they’ve published, at least two orders of magnitude smaller than what would be necessary. substack.com/home/post/p-177…
