1. Introduction to Ada: a project-based exploration with rosettas Total comment counts : 6 Summary This practical walkthrough documents a new AdaCore Field Engineer helping customers succeed with Ada. Recalling Ada’s fundamentals, the author uses a project-based approach—building a small end-to-end program that generates animated rosettas (hypotrochoid) as SVG files, a nod to Spirograph. The piece argues Ada is enjoyable beyond safety-critical domains and explores Ada 2022 features. It covers why Ada’s philosophy emphasizes readability, explicit typing, defined semantics, and a helpful compiler....

1. Patrick Winston: How to Speak (2018) [video] Total comment counts : 5 Summary error Top 1 Comment Summary The piece argues that success depends first on speaking, then writing, then the quality of ideas. It uses ChatGPT as an example: it can speak, write, and have ideas, but cannot perform physical tasks like hiking, swimming, or sports. The closing message: “Don’t be ChatGPT,” urging readers to develop real-world, physical capabilities alongside communication and ideas....

1. Eternal Struggle Total comment counts : 14 Summary error Top 1 Comment Summary Self-balancing: when one side grows larger by chance, its ball has more space and bounces less often, slowing growth; the smaller side’s ball bounces more in its smaller space, helping it catch up. Top 2 Comment Summary I can summarize, but I only see the title in your message. Please paste the article text (or a link) and I’ll summarize it in 100 words or fewer....

1. Are we decentralized yet? Total comment counts : 12 Summary This page uses the Herfindahl–Hirschman Index (HHI) to quantify concentration in the Fediverse and Atmosphere. HHI sums the squares of market shares of all servers (Fediverse instances; Atmosphere PDS hosting user data). Values near zero indicate competitive markets, while 10,000 signals a monopoly. Economics bands: <100 highly competitive, <1500 unconcentrated, >2500 highly concentrated. Bluesky Social PBC’s PDSes are aggregated since they’re controlled by one entity....

1. Do the simplest thing that could possibly work Total comment counts : 20 Summary The article argues for ‘do the simplest thing that could possibly work’ in software design, not chasing an ideal, highly-factorable system. Begin by deeply understanding the existing system, then implement the simplest solution that meets current requirements. As developers gain tool familiarity, avoid unnecessary infrastructure; leverage Unix primitives and existing components (e.g., edge proxies, caches) before building new pieces....

1. Ask HN: The government of my country blocked VPN access. What should I use? Total comment counts : 90 Summary To bypass censorship, obtain VPN software and obfuscated configurations from providers who distribute them in hard-to-block ways. Obfuscation layers (e.g., obfs4proxy with a pre-shared key, or pluggable transports like Shapeshifter) can help defeat DPI; the VPN provider must support these protocols. Long-term detection remains a challenge, as statistical analysis can reveal VPN use even with obfuscation....

1. Malicious versions of Nx and some supporting plugins were published Total comment counts : 45 Summary An incident where malicious nx versions and related packages were published to npm, containing a postinstall script that scanned the user’s filesystem, collected credentials, and posted them to a GitHub repo tied to the user. The script also altered .zshrc/.bashrc to run a shutdown command. An npm publish token was compromised. After detection, npm removed the affected versions and tokens, and later all Nx packages were restricted to 2FA and switched to a Trusted Publisher mechanism that does not use npm tokens....

1. Claude for Chrome Total comment counts : 50 Summary Anthropic is piloting Claude for Chrome to work directly in browsers, starting with 1,000 Max plan users via a controlled test and a waitlist. They view browser-enabled AI as inevitable but require stronger safety safeguards. In red-team tests, prompt injection attacks—where malicious content manipulates actions—showed a 23.6% success rate without mitigations across 123 test cases and 29 scenarios; a malicious email could trigger mass deletion....

1. Google’s Liquid Cooling Total comment counts : 6 Summary Liquid cooling is expanding from PC enthusiasts to datacenters, driven by AI’s power demands. Google highlights a datacenter-scale water loop for TPUs: CDUs (Coolant Distribution Units) in racks, two non-mixing liquid circuits, heat transferred via split-flow cold plates; TPUv4 uses bare-die for higher heat transfer. Liquid cooling cuts cooling power consumption (pumps use <5% of air-based fan power). In datacenters, maintenance is managed with no downtime via extra CDUs, extensive leak testing, alerts, and scheduled checks....

1. Looking back at my transition from Windows to Linux in an anti-customer age Total comment counts : 2 Summary An IT professional recounts his switch from Windows to Linux, driven by Windows 11 policies and a broader shift to subscription software. After years of attempted Linux use, he now runs entirely on Linux for two years, despite persistent pain points, and questions continuing support for Windows. He cites OneDrive data moves, hostile design, and a feudal trend as reasons to reclaim ownership and control....
