<li><strong>AWS doubles down on data center investment for AI</strong>: AWS announced plans to invest $200 billion in 2026 to double its data center capacity by the end of 2027, primarily for AI infrastructure. This follows a strong Q4 2025 with 24% year-over-year revenue growth, driven by traditional cloud migration and AI workloads. CEO Andy Jassy stated AWS is monetizing AI capacity as fast as it’s deployed, with custom Trainium accelerators and Graviton CPUs generating significant revenue. <a href="https://app.daily.dev/posts/1BAlXIloL" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Microsoft open-sources Rust-based sandboxing project LiteBox</strong>: Microsoft open-sourced LiteBox, an experimental library OS written in Rust, designed for application sandboxing with a minimal attack surface. Positioned between containers and VMs, it offers stronger isolation without heavy overhead by utilizing a library OS model with narrow interfaces. LiteBox supports AMD SEV-SNP for confidential computing and can run unmodified Linux applications across different platforms, though it’s not production-ready. <a href="https://app.daily.dev/feed-by-ids?id=jIlb9nmzq&amp;id=0PdnWmIzP" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>AI coding tools transform development but shift bottlenecks</strong>: AI coding assistants like NVIDIA’s Cursor, deployed to 30,000 developers, are reportedly tripling committed code and accelerating new developer ramp-up without increasing bug rates. However, this shifts the development bottleneck from code generation to coordination, reviews, and handoffs. Experts suggest that while AI makes coding nearly effortless, overall velocity requires changing systems and processes, emphasizing end-to-end ownership and optimizing for ‘cost per happy user’ over ‘cost per line of code’. <a href="https://app.daily.dev/feed-by-ids?id=1UoQrsDRG&amp;id=3IeScMbvD&amp;id=1S4Xqhe7b&amp;id=E1ox8iVPF&amp;id=hDRUbmwfg" target="_blank" rel="noopener nofollow">Read more</a></li>

<li><strong>PostgreSQL extensions replace specialized databases</strong>: For 99% of companies, Postgres with extensions like pg_textsearch, pgvector, and TimescaleDB can replace specialized databases like Elasticsearch, Pinecone, Redis, MongoDB, and InfluxDB, reducing operational complexity and infrastructure overhead. <a href="https://app.daily.dev/posts/QtM7zNGDf" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Snowflake integrates pg_lake for open data standards</strong>: Snowflake integrated <code>pg_lake</code>, an open-source PostgreSQL extension, into its Snowflake Postgres service, enabling direct SQL interaction with data lakehouses and Apache Iceberg tables, and expanding its Horizon Catalog for governance. <a href="https://app.daily.dev/posts/kBWxo6cQz" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Go language ecosystem updates</strong>: Microsoft released security-fixed Go builds, a Medium article detailed a scalable email ingestion pipeline using Go and DuckDB, and <code>tview</code> was highlighted as a Go package for building rich terminal-based user interfaces. <a href="https://app.daily.dev/feed-by-ids?id=27vA6E5rB&amp;id=RjCoRN7S0&amp;id=WFUKfQ0NK" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Python, Rails, and Django receive security and feature updates</strong>: The Python ecosystem saw discussions on JIT performance and Rust integration, Rails updated its codebase with improved debugging and <code>insert_all!</code> options, and Django released security patches for SQL injection and DoS vulnerabilities. <a href="https://app.daily.dev/feed-by-ids?id=3p16HuQId&amp;id=8gkBetvnO&amp;id=CtbDgV4IB&amp;id=JfIvov06L" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Swift expands cross-platform and AI integration</strong>: Swift’s cross-platform capabilities are growing, with Goodnotes sharing 100,000+ lines of Swift code via WebAssembly, and Xcode 26.3 introducing agentic coding support with a new Model Context Protocol (MCP) for AI agent integration. <a href="https://app.daily.dev/posts/NT977RqD0" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Linux kernel scheduling enhancements proposed</strong>: Cambridge researchers developed Latency-Aware Group Scheduling (LAGS) to boost Kubernetes cluster capacity by 10-20%, while a new Linux kernel patch series, Dynamic Housekeeping and Enhanced Isolation (DHEI), aims for dynamic CPU resource partitioning without reboots. <a href="https://app.daily.dev/feed-by-ids?id=cc5mbXUoZ&amp;id=sIpmbSkbv" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>AI agents disrupting SaaS business model</strong>: Apparently, AI agents are ‘fundamentally disrupting’ the SaaS business model, shifting from selling software tools to delivering outcomes directly. Anthropic’s Cowork plugins supposedly triggered ‘significant stock drops’ in major SaaS companies. Because, you know, a few plugins are totally going to collapse an entire industry overnight. It’s not like SaaS companies have been adapting for decades or anything. <a href="https://app.daily.dev/posts/zMRAHcD2R" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>AI is taking over open source</strong>: Tailwind CSS laid off 75% of its engineering team, not because of market conditions or internal strategy, but because AI tools generate code without developers visiting the documentation site. The article frames this as AI ‘taking over’ open source, when it sounds more like a business model reliant on documentation traffic got disrupted. Maybe the problem isn’t AI, but relying on ad revenue from docs for an open-source project. <a href="https://app.daily.dev/posts/uR7Q2jMhV" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Postman becomes an ‘everything app’</strong>: Postman’s latest updates transform it from an API client into an ‘everything app’ with AI agent builders, managed cloud servers, and internal terminals. This isn’t feature creep; it’s a ‘transformation’ that will ‘revolutionize’ your workflow. Or, you know, just make it a bloated mess that locks you into their ecosystem, forcing you to pay for features you don’t need while making simple tasks harder. But hey, ‘AI agent builders’! <a href="https://app.daily.dev/posts/O8Zfhee9v" target="_blank" rel="noopener nofollow">Read more</a></li>
