Building a real-time AI tutor for 5-year-olds
Hey HN! We've spent the good part of this past year building an AI tutor that teaches kids ages 4-9 reading, math, ESL and more. Getting an AI tutor to effectively teach a child turns out to be a really hard technical challenge, this took getting the underlying architecture right. Our tutor steers the UX in real-time and makes complex decisions on the fly. Doing both at conversation speed required us to replace the standard tool-use loop. We built our own tutor harness that utilizes a streaming interpreter that executes actions, while an asynchronous planner model reasons ahead of the conversation and makes calls that drive the child's learning. On top of it all, we developed a safety system that checks every turn without it causing an interruption to the activity and conversation flow. Effective teaching isn't just about answering a child's question quickly, rather making the right move at the right moment. AI is also going to be an integral part shaping how this generation of kids l

Show HN: RandoFont, a browser for Google Fonts
Inevitably when starting a new web project I want to pick the perfect font. This is just a browser that shows Google Fonts, randomly, and lets me tag favorites. I built this years ago and just used AI to give it a minor facelift. Comments URL: https://news.ycombinator.com/item?id=48852144 Points: 5 # Comments: 2

Dormant GitHub Accounts Help Attackers Blend In While Mapping Corporate Orgs
Datadog Security Labs is warning of "several overlapping campaigns" that are systematically enumerating corporate GitHub organizations, repositories, and user accounts through the GitHub API. "Operators rely on automated scraping tooling with custom or legitimate-sounding user agents, leveraging GitHub 'ghost' accounts that are often years old, or compromised OAuth tokens and personal

New GigaWiper Windows Backdoor Bundles Disk Wiping, Fake Ransomware, and Spyware
Microsoft has taken apart a destructive Windows backdoor it calls GigaWiper. What stands out is how it is built: not one tool but three older destructive programs bolted into one, offered as commands the operator can choose from. Each is a different way to break a machine: wipe the whole disk, overwrite the Windows drive, or run fake "ransomware" that scrambles files with a key it never saves

npm 12 Disables Install Scripts by Default to Reduce Supply Chain Risk
GitHub has officially announced the release of npm version 12 with install scripts disabled by default, along with deprecating granular access tokens (GATs) designed to bypass two-factor authentication (2FA). The Microsoft-owned subsidiary noted that the following npm install behaviors that used to run automatically before have been made opt-in - allowScripts defaults to off, meaning
How GitHub gave every repository a durable owner
GitHub had over 14,000 repositories. Fewer than half had clear ownership. Here's how we gave every active repository a validated owner in under 45 days, archived the rest, and made ownership the foundation for everything that followed. The post How GitHub gave every repository a durable owner appeared first on The GitHub Blog.

Lobsters Interview with mitchellh
@mitchellh (blog) was behind Vagrant, Packer, Consul, Terraform, Vault, Nomad, Waypoint and now builds Ghostty and Vouch. In this interview, we talk about terminals, Zig and open source. You've been interviewed a lot. Why do people like to interview you? In interviews, everyone comes from a different angle. Many people want to know how the software engineering to business founder mindset transition went. Then others are interested in product stuff, the work I did at Hashicorp or Ghostty now. What's different here is there's no known agenda coming into it; neither of us have anything to sell. What do you find so fun about terminals? Like, why Ghostty? I spent ~15 years building CLI applications (not TUIs like we see nowadays). Through that process, I accidentally learned how to color things, move cursors etc. Leaving Hashicorp, I wanted to sharpen my technical skills (where they'd grown dull from neglect) and specifically work on: Pre-AI GPU programming, desktop/single node systems prog
