Spending weeks merging assay files? One file can hold every assay. I built a skill that auto-assembles linked data packages. One curator manages many campaigns. How would you feel about shipping instead of wrangling? ericmjl.github.io/blog/2026/7/... #xarray #bioinformatics

What if your LLM woke in seconds, not minutes? Tested Ollama vs vLLM on Modal (Qwen3.6-27B). vLLM wins on cold starts and throughput. Post: setup, 3 snapshot bugs, CUDA graphs. How do you handle cold starts? buff.ly/e8LX5OE #llm #vllm

formats evolve over decades, apps over months, intelligence is evolving every day in terms of pace layers "file over app" defines priorities: invest deeply in proven formats, and don't expect anything at the intelligence layer to last very long

I wonder if this will make people reconsider their stance or become even more defensive.
Does AI widen the expert-novice gap? Live-demoed a Bayesian model with an agent. It amplified my judgment. For experts, a microscope. For novices, fast wrong answers. 'Vibe zones' and trust scaling with verification. What's your experience? #ai #datascience buff.ly/BVb49jC

What if your agent learned from its mistakes without you telling it to? I built a plugin that watches sessions, extracts lessons, and patches skills. 922 observations, 200+ reviews in 10 days. It patched a skill on its own. No babysitting. #opencode #aiagents ericmjl.github.io/blog/2026/6/...

Stuck switching branches without losing half-finished work? I use git worktrees now. Multiple doors into the same repo: no syncing, no duplication, separate folders sharing one brain. One brain, many desks. What's your go-to trick? #git #programmingtips buff.ly/B8p0Xt6

📚 Learn from experts during two full days of tutorials, covering everything from Python fundamentals to advanced topics such as GPU-accelerated computing, machine learning, and building AI-powered coding assistants using retrieval-augmented generation (RAG).
💛 It's where maintainers meet first-time contributors. Where researchers discover tools that transform their work. Where students find mentors. Where hallway conversations become collaborations, papers, startups, and open-source projects used by millions around the world.
🎉 Less than one month until #SciPy2026! 👉️ ti.to/scipy/scipy2... When people ask what SciPy is, it's tempting to say it's a conference about Python for scientific computing. But SciPy has always been much more than that.
At some point, you have to flip the switch from "it's dangerous to let everyone have this for offense" to "it's dangerous not to let everyone have this for defense." The jailbreak is credible but IMO the decision wasn't substantive. Anthropic created glasswing to prepare for this exact need.
conputer dipshit@davidcrespo.bsky.social · 2mo agooh shit: someone who has actually read the report on the “jailbreak”. she‘s backing up Anthropic’s story that it’s nothing. they got fable to help fix some code with planted vulns www.lutasecurity.com/post/the-fab...

Nico Dosenbach@ndosenbach.bsky.social · 2mo agoWe've known that socioeconomics (SES) matters for the 🧠. New & 🤯 is that SES drowns out all other brain associations, incl. IQ. If you train an algorithm to predict IQ from brain data, it's still way better at predicting SES. Science Mag: www.science.org/doi/10.1126/... @smarek0502.bsky.social 👀🧵👇

How Jeffrey Epstein took advantage of a lenient Florida jail and kept exploiting women
An NBC News investigation shows that Epstein’s first stint in jail was hardly an interruption. Even behind bars, he continued associating with the rich and famous and supporting his lavish lifestyle.
