Linus Torvalds: Vibe coding is fine, but not for production
Linus Torvalds shares his perspective on AI-assisted coding, stating that while vibe coding can help newcomers get started with programming, it's unsuitable for production code due to maintenance concerns. He discusses Rust's gradual integration into the Linux kernel, noting it has taken longer than expected but is becoming a real part of the codebase. Torvalds addresses AI's impact on kernel development, mentioning issues with crawlers disrupting infrastructure and AI-generated bug reports, though these problems are less severe than in other projects. He compares AI to previous productivity tools like compilers, suggesting it won't eliminate programming jobs but will change how developers work.

How To Become Elite at Programming
Becoming an elite programmer requires three key principles: doing it for fun rather than money, documenting your work through GitHub or content creation, and continuously developing skills through deliberate practice. The most successful engineers are driven by genuine interest, which allows them to naturally invest time in improving without forced productivity systems. Quality practice matters more than quantity, and surrounding yourself with excellent examples accelerates growth. Finding what genuinely interests you within programming is the foundation for reaching elite status.

Affinity for Linux? Canva’s next big move could reshape the desktop software market
Canva is seriously considering porting its Affinity creative software suite to Linux, which could be transformative for desktop Linux adoption. Currently, professional designers are locked into Windows and macOS due to Adobe's Creative Cloud dominance. Affinity, recently made free by Canva, is the only full-scale commercial alternative to Adobe. This potential move comes as Linux gaming has matured through Valve's Steam Deck, and dissatisfaction with Windows grows due to intrusive telemetry and AI features. A Linux port would enable designers, photographers, and content creators to run fully Linux-based workflows, potentially triggering wider desktop Linux adoption and challenging Adobe's market position.

Small Repo, High Quality
Breaking software into smaller repositories instead of using monolithic repos improves code quality through stricter style enforcement, deeper testing, more thorough code reviews, better documentation, faster release cycles, improved AI agent effectiveness, quicker onboarding, stronger code ownership, and easier open-source adoption. While companies like Google and Facebook favor monorepos for reduced integration overhead, smaller repositories enable teams to maintain higher quality standards across multiple dimensions of software development.

Elixir → JavaScript Porting Initiative
Hologram needs community help porting 171 Erlang standard library functions to JavaScript to enable Elixir execution in browsers. The project is 34% complete for Phase 1, which focuses on full-stack web applications. Contributors don't need deep Erlang knowledge - just basic JavaScript and Elixir skills to follow existing patterns. Tasks range from 15 minutes to a few hours, and AI tools are encouraged. Each ported function unlocks multiple Elixir stdlib functions, creating a multiplier effect for the community.

Yes really, curl is still developed
curl's lead developer addresses the common misconception that the project is no longer actively developed. Despite maintaining a stable user interface for decades, curl is currently experiencing its highest development activity ever. The project continuously evolves to keep pace with changing internet standards, protocols, and security requirements while prioritizing backwards compatibility. The team refactors internal architecture regularly without breaking existing APIs or command-line interfaces, viewing this stability as curl's core strength. With nearly 30 years of history, the project is being developed with the mindset that it could remain relevant for another 70 years.

Olmo 3 is a fully open LLM
Ai2 released Olmo 3, a fully open LLM series that includes complete training data, process, and checkpoints. The flagship 32B Think model emphasizes interpretability with visible reasoning traces through OlmoTrace. Trained on 5.9 trillion tokens from the Dolma 3 Mix dataset (6x fewer tokens than competitors), it offers four 7B variants and two 32B models. The release enables auditing training data to detect potential backdoors, addressing security concerns in open-weight models. Performance testing shows improved SVG generation compared to Olmo 2, though OlmoTrace's training data attribution needs refinement.

your project fucking sucks
Open-source communities face pollution from low-effort, dishonest projects that prioritize marketing over substance. These "slop projects" mimic the aesthetics of legitimate open-source work with fancy websites, contribution guidelines, and roadmaps, but lack real problem-solving value. The author argues for cultural gatekeeping to preserve open-source values, distinguishing between beginner mistakes (acceptable) and dishonest performance (harmful). Red flags include AI-generated content, premature community scaffolding, tech-stack-focused descriptions, and projects announced before implementation. The solution is simple: build real things that solve actual problems, or be honest about learning projects.

Perplexity’s open-source tool to run trillion-parameter models without costly upgrades
Perplexity AI released TransferEngine, an open-source tool that enables trillion-parameter language models to run across different cloud providers' GPU hardware at full speed. The software solves vendor lock-in by creating a universal interface for GPU-to-GPU communication that works on both Nvidia ConnectX and AWS EFA networking protocols. This allows companies to run massive models like DeepSeek V3 and Kimi K2 on older H100 and H200 systems instead of purchasing expensive next-generation hardware. TransferEngine achieves 400 Gbps throughput using RDMA technology and is already powering Perplexity's production AI search engine, handling disaggregated inference, reinforcement learning, and Mixture-of-Experts routing.

Internet Archive’s legal fights are over, but its founder mourns what was lost
The Internet Archive recently archived its trillionth webpage and was designated a federal depository library, but founder Brewster Kahle reflects on the cost of recent copyright battles. Legal fights forced the removal of over 500,000 books from the Open Library, though the organization survived and currently faces no major lawsuits. Despite the setbacks to its digital library mission, Kahle continues moving forward with new initiatives while the Wayback Machine remains operational after nearly 25 years.

What a Shame! FlatHub is Ranking on Google for Po*nHub Downloads
Flathub, the official Flatpak app store, is ranking highly on Google for adult content downloader searches due to a developer exploiting its reputation. A developer named Warlord Software published three downloader applications on Flathub and tagged them with NSFW keywords, leveraging Flathub's domain authority to gain over 250,000 downloads for proprietary apps with premium licenses. The developer's own website contains no mention of these keywords, revealing a deliberate SEO exploitation strategy that uses Flathub's trusted platform to rank for competitive search terms that would be impossible for a new site to achieve.

Linus Torvalds — Speaks up on the Rust Divide and saying NO
Linus Torvalds discusses the ongoing integration of Rust into the Linux kernel, acknowledging the friction and maintainer pushback it has created over the past five years. He defends the decision as necessary to prevent kernel stagnation and attract new contributors, noting his role has shifted from saying 'no' to encouraging maintainers to embrace new ideas. While Rust has generated controversy including maintainer resignations and debates over code review processes, Torvalds believes the disruption is worthwhile and that Rust is finally transitioning from experimental to a real part of the kernel, though it took longer than expected.

Servo 0.0.2 hints at a real Rust alternative to Chromium
Servo 0.0.2, a browser rendering engine written entirely in Rust, represents a potential alternative to Chromium's dominance in web browsers and embedded applications. Originally developed by Mozilla and Samsung starting in 2012, the project was revived under the Linux Foundation Europe and recently began issuing numbered releases. While still in early development (version 0.0.2), Servo offers advantages in security, performance, and independence from Google's ecosystem. The engine could eventually challenge Chromium's monopoly in both standalone browsers and embedded web components like Electron, though a production-ready version remains distant.
