<li><strong>Google’s embedding model deprecation causes vendor lock-in</strong>: Google deprecated its <code>text-embedding-004</code> model, rendering thousands of stored vectors unusable for a production RAG-based movie recommender. This highlights a critical issue: different embedding models produce incompatible vector spaces, creating a hidden form of vendor lock-in. The author, in a post from February 22, 2026, emphasizes that persisted embeddings couple data to a specific model’s geometry, not just an API, necessitating a complete re-embedding and re-validation process. <a href="https://app.daily.dev/posts/xhDI1zj4i" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Databricks launches Lakebase for AI workloads</strong>: Databricks launched Lakebase, a new PostgreSQL-compatible database specifically designed for AI workloads. It aims to bridge operational database capabilities with their data lakehouse architecture, offering a serverless OLTP database that separates compute from storage. Currently GA on AWS with Azure in public preview, Lakebase supports up to 8TB per instance and includes Postgres 17 with pgvector support, as announced on February 22, 2026. <a href="https://app.daily.dev/posts/56RHAShlB" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Linux kernel 7.0 rc1 released, Rust support cemented</strong>: Linus Torvalds released Linux kernel 7.0 rc1, noting the major version bump is purely for numerical reasons, not a significant feature milestone. This release includes cemented Rust support, faster cache clearing, non-disruptive kernel update capabilities, and updated AMD/Intel silicon support. Torvalds also mused about a future maintainer, referencing the community’s recently developed succession plan, as reported on February 23, 2026. <a href="https://app.daily.dev/posts/cYP8biu57" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>Anthropic’s compiler video: more marketing than magic</strong>: Anthropic released a marketing video showcasing Claude autonomously building a C compiler capable of compiling Linux and Doom. Critics, however, claim the video used “dishonest framing,” suggesting the actual goal was a stress test of Claude’s extended autonomous operation, not a straightforward demonstration of compiler-building prowess. So, another day, another AI marketing video that needs a fact-check. <a href="https://app.daily.dev/posts/vGYk0DbTO" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Meta patents AI to simulate deceased users</strong>: Meta was granted a patent for an AI system designed to simulate a user’s social media activity, including posting and chatting, using an LLM trained on their past data when the user is ‘absent.’ Because nothing says ‘we care about your mental health’ like having a digital zombie of you wandering around Facebook, as if the platform wasn’t creepy enough already. <a href="https://app.daily.dev/posts/AeW0pHCcd" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Neiry tests ‘bio-drones’ with neural interface pigeons</strong>: Neiry, a deeptech company, announced early real-world testing of ‘bio-drones’—live pigeons fitted with neural interfaces, solar panels, and cameras, guided by mild brain stimulation. They claim these birds can cover 400 km daily for infrastructure inspection and search-and-rescue. Because apparently, regular drones are too boring, and we needed to strap computers to pigeons for ‘privacy-compliant’ surveillance. What could possibly go wrong? <a href="https://app.daily.dev/posts/m7v8MA0Dh" target="_blank" rel="noopener nofollow">Read more</a></li>
