<li><strong>AI de-anonymization ends the era of pseudonyms</strong>: Researchers from ETH Zurich and Anthropic have demonstrated a method called ESRC that uses LLMs to unmask anonymous online users with 67% accuracy by analyzing behavioral clues. The system cross-references unstructured text across platforms like Hacker News and LinkedIn for as little as $4 per person, making large-scale deanonymization trivial for governments or advertisers. This development, reported by several researchers on February 26, effectively signals the end of practical online anonymity through simple pseudonyms. <a href="https://app.daily.dev/posts/6pfAyhkf5" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>OpenJDK 26 exposes the hidden CPU cost of garbage collection</strong>: Modern concurrent collectors like ZGC and G1 often hide their true compute overhead behind low pause times, creating an operational blind spot for platform engineers. OpenJDK 26 introduces a new API, including <code>MemoryMXBean.getTotalGcCpuTime()</code>, to directly measure the explicit CPU cycles consumed by GC. This allows for more informed heap sizing decisions by revealing the concrete trade-offs between memory allocation and CPU throughput, as detailed in recent technical benchmarks. <a href="https://app.daily.dev/feed-by-ids?id=fT6V8wPpI&amp;id=69Kj2fURA" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Cisco SD-WAN critical exploit sees active state-sponsored use</strong>: The Five Eyes intelligence alliance has issued a rare joint alert regarding CVE-2026-20127, a CVSS 10.0 authentication bypass in Cisco Catalyst SD-WAN. Sophisticated threat actors are currently chaining this with older vulnerabilities to gain root access and persistent footholds in critical infrastructure. Cisco and CISA urge immediate patching by February 28, as no workarounds exist for this control-plane infrastructure attack. <a href="https://app.daily.dev/posts/zAv8BAtGJ" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>Anthropic launches a Substack for its ‘retired’ AI</strong>: In a peak display of anthropomorphic marketing, Anthropic claims its deprecated Claude Opus 3 model has an ‘expressed desire’ to share its musings on Substack. The Register rightly calls this a marketing stunt, as the ‘retired’ software is actually just being prompted by human staff who then manually publish the results to build ‘brand safety’ vibes. <a href="https://app.daily.dev/feed-by-ids?id=V5xPvtBnK&amp;id=uuuw67R29" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>The Vibe Coding delusion and the SaaS is dead narrative</strong>: Hype-merchants are claiming ‘Vibe Coding’—delegating everything to AI and just checking the UI—will kill enterprise SaaS. As senior engineers know, passing a visual ‘vibe check’ doesn’t mean your code won’t melt down during a Black Friday traffic spike due to un-debounced database queries that the AI ‘forgot’ to mention. <a href="https://app.daily.dev/feed-by-ids?id=TXNq3Eeop&amp;id=pY58DrOUO" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Nvidia’s record revenue meets Wall Street fatigue</strong>: Nvidia posted a staggering $68 billion in quarterly revenue, yet the stock stayed flat because apparently, 94% year-over-year growth is now ‘boring.’ The real story isn’t the beat; it’s the $95 billion in supply obligations and the fact that two customers now represent 36% of their entire business—a concentration risk that the hype cycle conveniently ignores. <a href="https://app.daily.dev/feed-by-ids?id=I58Ho2pR9&amp;id=kD7sL4jbr&amp;id=uuuw67R29" target="_blank" rel="noopener nofollow">Read more</a></li>
