<li><strong>Cursor launches Composer 2 with self-summarization tech</strong>: Cursor has released Composer 2, an in-house model that uses a reinforcement learning technique called self-summarization to compress its context window to 1,000 tokens when limits are hit. The company claims this reduces compaction errors by 50% compared to traditional sliding window methods and outperforms Claude 4.6 on terminal-based benchmarks. Most notably, Cursor is pricing this at a fraction of Anthropic’s flagship costs, signaling a shift toward more sustainable long-horizon coding agents. <a href="https://app.daily.dev/posts/mIKxoNmwG" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Interlock ransomware exploits Cisco zero day with CVSS 10</strong>: A critical vulnerability in Cisco Secure Firewall Management Center (CVE-2026-20131) was exploited in the wild for over a month before a patch was available. Amazon’s MadPot honeypot network revealed that the Interlock group used this deserialization flaw to achieve remote code execution across healthcare and government sectors. Security teams are urged to apply the March 4 patch immediately to prevent further automated exploitation. <a href="https://app.daily.dev/posts/kS1FWAP6y" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Google AI Studio pivots to full stack vibe coding</strong>: Google has updated AI Studio with a ‘Build Mode’ that generates entire applications, including frontend UI and backend logic, from natural language prompts. The update integrates a new agent that maintains context across multi-file projects and offers native Firebase integration for instant database and auth setup. This move directly challenges the developer experience offered by tools like V0 and Cursor by streamlining deployment to Cloud Run. <a href="https://app.daily.dev/posts/vDejXlEPp" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>The smartphone app is dead again says Nothing CEO</strong>: Carl Pei is the latest to claim AI agents will kill apps, envisioning a future where your phone ‘understands intent’ to book coffee dates. It’s a convenient narrative for a hardware company trying to differentiate itself, but it ignores the reality that users actually like visual interfaces and predictable controls. We’ve heard ‘apps are dead’ since the first chatbots in 2016, yet here we are, still tapping icons because talking to a black box is a UX nightmare. <a href="https://app.daily.dev/posts/69QgfhMta" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>AI is rotting your brain according to Stack Overflow</strong>: A new blog post cites research warning that ‘belief offloading’ to AI will create an ‘algorithmic monoculture’ and erode your self-confidence. While the risks of over-reliance are real, framing 0.076% of conversations as a ‘disempowerment’ crisis feels like a reach for academic relevance. It’s the classic ‘kids these days can’t use a slide rule’ argument, updated for the LLM era to make us feel guilty about automating the boring stuff. <a href="https://app.daily.dev/posts/BbYdrSqWL" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>The pivot to AI engineering is just software engineering</strong>: Tech With Tim’s ‘fastest way to pivot’ guide eventually admits that you actually just need to be a good software engineer who knows Python and math. The industry is currently flooded with ‘AI Engineer’ roadmaps that are really just standard CS curriculums with a ‘sponsored by an LLM course’ sticker slapped on top. If your ‘pivot’ takes 12 months of learning foundations, you’re not pivoting; you’re just finally learning how to code properly. <a href="https://app.daily.dev/posts/fjq3q7FXL" target="_blank" rel="noopener nofollow">Read more</a></li>
