4I found 10k GitHub repositories distributing Trojan malware
- The author discovered 10,000 malicious GitHub repositories that copy legitimate projects and add links to zip files containing Trojan malware in their README files. These repositories update every few hours by deleting and re-pushing commits, likely to evade detection algorithms. The author created a script to identify these repositories using patterns like frequent updates, copied commits from other repos, and README modifications. GitHub eventually began deleting the identified repositories after the findings were published.
Malware targeting AI agents and elections
Attackers are creating malicious GitHub repos to target automated agents rather than humans, potentially to steal social media accounts for election manipulation. They constantly refresh repos to appear in search results and exploit the rise of AI agents.GitHub's inadequate response to malware

Discussion sparked by Disney engineer who was compromised through malicious GitHub code that accessed his 1Password. Users debate separating TOTP/MFA from password managers and using dedicated devices for sensitive accounts.
5Microsoft new Outlook takes 10 seconds to do what Outlook Classic does instantly
- Microsoft's new Outlook for Windows has a significant performance problem with email notifications. While clicking a notification in Outlook Classic opens the email almost instantly, the new Outlook takes around 10 seconds to display the same email after clicking its notification. This delay occurs because the new Outlook is built on WebView2 technology, essentially running as a web browser wrapper that uses multiple processes and consumes significantly more memory and CPU than the classic version. The web-based architecture creates inherent performance limitations that cannot be easily fixed through updates, making Outlook Classic the more reliable choice for users who prioritize fast notification handling.

Users criticize AMD's artificial restriction of features to enterprise SKUs, comparing it to BMW's subscription heated seats and arguing that enterprises pay for more than just standalone features like memory encryption.Post-sale feature removal concerns
Many express anger about AMD silently removing features via firmware updates, calling it "post-sale enshittification" and arguing it sets dangerous precedent for future product degradation after purchase.
10AI demands more engineering discipline. Not less
- The author responds to feedback on their previous AI piece, clarifying they don't advocate abandoning code review but rather embracing AI's rapid improvement in code generation. They argue that AI has fundamentally changed software economics, making code disposable rather than precious, and advocate for "Phoenix Architectures" where regenerating code is preferred over editing existing code, similar to how immutable infrastructure replaced handcrafted servers.
Quality control in AI-generated code
Engineers struggle to distinguish between those who understand systems and effectively use AI versus those who just generate LLM output. This creates massive technical debt as code reviews become overwhelmed with superficially plausible but potentially problematic AI-generated content.Economics of code production transformation
The shift from code being expensive and time-consuming to create to becoming free and instant has fundamentally changed development priorities. This enables building previously unjustifiable features and entire projects that wouldn't have been worth manual effort.Alternative artifacts for development workflow
Discussion centers on moving away from code as the primary review artifact toward focusing on prompts, plans, and specifications that generate the code, similar to infrastructure-as-code practices.
