<ul>
<li><strong>Claude Code adds parallel agents and batch migrations</strong>: Anthropic has significantly upgraded its Claude Code CLI with new skill agents like <code>/simplify</code> and <code>/batch</code>. The <code>/batch</code> command is particularly impactful for backend refactoring, as it spawns dozens of isolated agents using git worktrees to handle large-scale migrations and PR submissions in parallel. These updates, detailed in the latest release notes, also include HTTP hook handlers for integrating the CLI directly into CI/CD pipelines or custom validation scripts. <a href="https://app.daily.dev/posts/sq7rTuWl2" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Critical ReDoS vulnerabilities hit minimatch package</strong>: Three high-severity vulnerabilities (CVE-2026-27904, 27903, 26996) were patched in <code>minimatch</code>, a core npm dependency with nearly 500 million weekly downloads. These flaws involve catastrophic backtracking in nested glob patterns that can stall the Node.js event loop for several seconds. Socket has released free certified patches that can be applied via their CLI without requiring a full dependency tree upgrade, as reported by security researchers. <a href="https://app.daily.dev/feed-by-ids?id=2WnWCE8iO&amp;id=89yzay3k6" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Netflix solves container scaling bottleneck on modern CPUs</strong>: Netflix engineers identified a major performance regression when migrating to kubelet with per-container user namespaces, causing 30-second timeouts during container launches. The issue stemmed from O(n) mount operations competing for global VFS locks, a problem amplified by Intel’s centralized mesh architecture compared to AMD’s chiplet design. A fix has been contributed upstream to <code>containerd</code> that reduces mount operations to O(1), effectively eliminating the bottleneck for high-density deployments. <a href="https://app.daily.dev/posts/cKVVAN6ve" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>The AWS SDK for .NET is a million-violation dumpster fire</strong>: A recent code quality audit uncovered nearly 960,000 violations, including widespread IDisposable misuse that guarantees memory leaks in production. The SDK contains over 12,000 blocks of cloned code and 8,000 missing unit tests, proving that even trillion-dollar companies can’t be bothered to follow basic engineering principles. If you’re trusting this in a high-scale environment, you’re essentially volunteering for an uncompensated on-call shift. <a href="https://app.daily.dev/posts/1ODSYlFQR" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Cloudflare cloned Next.js in a week using AI and it’s fine</strong>: Cloudflare is bragging about using AI agents to rebuild a Next.js-compatible framework called Vinxi just to spite Vercel. While they claim 4x faster builds, they conveniently left out minor details like static pre-rendering, which is basically the whole point of the framework they’re cloning. It’s a classic ‘look at our AI’ flex that prioritizes marketing benchmarks over actual feature parity. <a href="https://app.daily.dev/posts/5XUEq41aC" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Web development is quietly returning to PHP</strong>: Opinion pieces are currently framing the industry’s realization that SSR and file-based routing are good ideas as a ‘return to PHP.’ In reality, modern JS frameworks are just reinventing the wheel with 10x the complexity and calling it ‘maturity’ instead of admitting PHP had it right a decade ago. It’s not a homecoming; it’s just the hype cycle finally running out of new ways to over-engineer a simple CRUD app. <a href="https://app.daily.dev/posts/S646eUkOf" target="_blank" rel="noopener nofollow">Read more</a></li>
