<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 vendor lock-in issue: different embedding models produce incompatible vector spaces, making migration difficult. The author, writing on February 22, 2026, emphasizes treating embedding models as infrastructure and designing for change if persisting embeddings at scale. <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 with features like instant data branching and pgvector support. This move, announced on February 22, 2026, positions Databricks to capture more of the AI infrastructure market, with GA on AWS and Azure support in public preview. <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</strong>: The Linux kernel 7.0 rc1 was released, with Linus Torvalds humorously attributing the major version bump to his confusion with large numbers, not a significant feature milestone. The release, however, includes cemented Rust support, faster cache clearing, non-disruptive kernel updates, and updated AMD/Intel silicon support. This continues the kernel’s steady evolution, 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 Claude compiler video: more hype than substance?</strong>: Anthropic released a marketing video showcasing Claude autonomously building a C compiler capable of compiling Linux, SQLite, Lua, and Doom. Critics, however, are calling out the “dishonest framing,” suggesting the actual goal was merely a stress test of Claude’s ability to run autonomously for an extended period. So, it compiled Doom, but did it <em>understand</em> Doom? Probably not. <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 that simulates a user’s social media activity, including posting and chatting, using their past data when they’re ‘absent’ from the platform. Because nothing says ‘we care about your mental health’ like an AI ghost of your deceased loved one popping up in your feed. Just what we needed, more digital necromancy from the metaverse overlords. <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 absolutely need pigeons with brain implants to check power lines. What could possibly go wrong? <a href="https://app.daily.dev/posts/m7v8MA0Dh" target="_blank" rel="noopener nofollow">Read more</a></li>
