🔥 Read this awesome post from Hacker News 📖 📂 Category: ✅ Here’s what you’ll learn: column "It's always DNS" is a long-standing sysadmin saw, and with good reason: a disproportionate number of outages are at their heart DNS issues.

You can find my previous timed post here.Are we getting smarter? Are we getting dumber? Headlines and anecdotes are bisexual about these questions.

🚀 Discover this awesome post from Hacker News 📖 📂 Category: 📌 Key idea: A while back, Google DeepMind unveiled Gemini Diffusion, an experimental language model that generates text using diffusion. Unlike traditional GPT-style models that generate one word at a time, Gemini Diffusion creates whole blocks of text by refining random noise step-by-step.I read the paper Large Language Diffusion Models and was surprised to find that discrete language diffusion is just a generalization of masked language modeling (MLM), something we’ve been doing since 2018.
