<ul>
<li><strong>Linux kernel 7.0 rc1 released with succession commentary</strong>: Linus Torvalds dropped Linux kernel 7.0 rc1, noting the major version bump is purely for his numerical sanity, not a feature milestone. This release solidifies Rust support, brings faster cache clearing, non-disruptive kernel updates, and updated silicon support. Torvalds also mused about a future maintainer, hinting at the community’s recently developed succession plan, as reported by multiple sources. <a href="https://app.daily.dev/feed-by-ids?id=cYP8biu57&amp;id=8ssuMcdSU&amp;id=JXfUDc5F4&amp;id=QdVE1yqfx&amp;id=TcabAvodN&amp;id=cQun6gD6y&amp;id=zaDpYuaxU" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Databricks launches Lakebase for AI workloads</strong>: Databricks introduced Lakebase, a new PostgreSQL-compatible database tailored for AI workloads. It aims to merge operational database capabilities with their lakehouse architecture, offering a serverless OLTP database that separates compute from storage. Lakebase supports up to 8TB per instance, includes Postgres 17 with pgvector, and is generally available on AWS, with Azure support in preview. <a href="https://app.daily.dev/posts/56RHAShlB" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Google 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 create incompatible vector spaces, making migration difficult and creating a hidden form of vendor lock-in. The author had to re-embed their entire dataset and re-validate retrieval quality, emphasizing the need to design for change when persisting embeddings at scale. <a href="https://app.daily.dev/posts/xhDI1zj4i" target="_blank" rel="noopener nofollow">Read more</a></li>

<li><strong>Developer productivity hindered by non-coding tasks</strong>: A developer’s 10-second code fix took over 10 hours due to non-coding tasks like fighting sandboxed environments, CUDA conflicts, and build failures, highlighting that most programmer time is lost to abstraction layers and tooling overhead. <a href="https://app.daily.dev/posts/OBIqfWI7x" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Rust RwLock can be slower than Mutex for read-heavy workloads</strong>: A hands-on investigation found that <code>RwLock</code> performed significantly worse than <code>Mutex</code> for a read-heavy LRU tensor cache in Rust due to cache-line ping-pong from atomic reader counter increments, suggesting <code>Mutex</code> might be better for very short critical sections. <a href="https://app.daily.dev/posts/rFMs5918e" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Fileless privilege escalation in hybrid AD environments</strong>: A red team case study detailed a 13-step fileless attack chain that escalates a low-privileged domain user to Domain Admin and Azure AD Global Admin by exploiting SQL impersonation, linked server pivots, and Azure AD Connect credential exposure. <a href="https://app.daily.dev/posts/u1TVqzV8C" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>VS Code extension ‘Fresh File Explorer’ released</strong>: A new VS Code extension, ‘Fresh File Explorer,’ replaces the standard file explorer to display recently modified files, integrating Git history and offering features like a recency heatmap, ‘Resurrect’ for deleted files, and various grouping modes. <a href="https://app.daily.dev/posts/pQedWHBRB" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Shuru: Local-first MicroVM sandbox for AI agents on macOS</strong>: Shuru is a new macOS-based microVM sandbox tool for AI agent workloads, using Apple’s Virtualization.framework to provide secure, ephemeral, and reproducible Linux environments without Docker, enabling safe execution of AI-generated code. <a href="https://app.daily.dev/posts/TqgsBjEoV" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>JDK 24 security enhancements</strong>: JDK 24 introduces significant security enhancements, including post-quantum cryptography support (ML-KEM, ML-DSA), core cryptography improvements, PKI updates, and the permanent removal of the Security Manager. <a href="https://app.daily.dev/posts/TLN02dr7b" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Passkey technology overview</strong>: Passkeys use public/private key cryptography for authentication, offering enhanced phishing resistance compared to passwords, though they introduce device dependency for authentication. <a href="https://app.daily.dev/posts/aWiqcUWV2" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>Anthropic’s Claude compiler video criticized for dishonest framing</strong>: Anthropic released a marketing video showcasing Claude autonomously building a C compiler capable of compiling Linux and Doom. Critics are calling out the ‘dishonest framing,’ suggesting the video was more about stress-testing Claude’s autonomy than a straightforward compiler-building demo. Apparently, we’re still in the era where AI companies need to exaggerate capabilities to get attention, because a simple ‘stress test’ just isn’t sexy enough. <a href="https://app.daily.dev/posts/vGYk0DbTO" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>China’s ‘kung fu robots’ changing everything</strong>: China showcased Unitree Robotics’ G1 humanoid robots doing martial arts at its Spring Festival Gala, with a clickbait article claiming this ‘changed everything’ and that China is replicating its EV dominance playbook in robotics. Because a few backflipping robots at a gala definitely mean Western competitors are doomed by 2028. Let’s not get ahead of ourselves; impressive demo, but ‘everything’ is a bit much. <a href="https://app.daily.dev/feed-by-ids?id=UN40kBCVc&amp;id=hPdh434Wa" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Neiry begins bio-drone testing with neural interface pigeons</strong>: Neiry, a deeptech company, announced early real-world testing of ‘bio-drones’—pigeons with implanted neural interfaces, solar panels, and cameras, claiming they can cover 400 km daily for ‘infrastructure inspection’ and ‘privacy compliance.’ Because nothing says ‘privacy’ like a pigeon with a brain implant and a camera, guided by mild brain stimulation. I’m sure the birds are thrilled about their new ‘careers’ as surveillance units. <a href="https://app.daily.dev/posts/m7v8MA0Dh" target="_blank" rel="noopener nofollow">Read more</a></li>
