How carrying enough water to make return-trip propellant simplifies a Starship mission to MarsThe idea of a human mission to explore Mars has been studied repeatedly over the past 75 years. More than 1,000 piloted Mars mission studies were conducted inside and outside NASA between about 1950 and 2000. Many were the product of NASA and industry study teams, while others were the work of committed individuals or […] The post How carrying enough water to make return-trip propellant simplifies a Starship mission to Mars appeared first on SpaceNews.

We’ve been doing lots of remote science, […]
Launch HN: Datafruit (YC S25) – AI for DevOpsIMAGE

Launch HN: Datafruit (YC S25) – AI for DevOpsHey HN! We’re Abhi, Venkat, Tom, and Nick and we are building Datafruit (https://datafruit.dev/), an AI DevOps agent. We’re like Devin for DevOps. You can ask Datafruit to check your cloud spend, look for loose security policies, make changes to your IaC, and it can reason across your deployment standards, design docs, and DevOps practices.Demo video: https://www.youtube.com/watch?v=2FitSggI7tg.Right now, we have two main methods to interact with Datafruit:(1) automated infrastructure audits— agents periodically scan your environment to find cost optimization opportunities, detect infrastructure drift, and validate your infra against compliance requirements.(2) chat interface (available as a web UI and through slack) — ask the agent questions for real-time insights, or assign tasks directly, such as investigating spend anomalies, reviewing security posture, or applying changes to IaC resources.Working at FAANG and various high-growth startups, we realized that infra work requires an en
Show HN: AgentCheck – Local AI-powered code review agents for Claude CodeIMAGE

Show HN: AgentCheck – Local AI-powered code review agents for Claude CodeI just want code reviews to be useful. They should be about trade-offs, sharing knowledge, and holding each other accountable, not on policing style, naming quirks, or catching trivial regressions and security issues. Tools similar to Cursor Bugbot flood PRs with noise, run in a black box, and bill you per seat for the privilege... they try to solve problems too late, in the wrong place, and without your developer environment tools.That turned into AgentCheck: an open-source subagent that runs locally with five focused reviewers - logic, security, style, guidelines, and product. It bakes in a lot of internal experience in building enterprise products, working in agentic-native SDLC, and solving Claude Code shenanigans. If you’re curious about the internals or have ideas for new reviewers, feel free to ask questions or contribute.

Ask HN: What toolchains are people using for desktop app development in 2025?IMAGE
news.ycombinator.com• Aug 9, 2025• 1 min read
Ask HN: What toolchains are people using for desktop app development in 2025?I recently came across a comment [0] here that highlighted the challenges of building native desktop apps with LLMs. The commenter pointed out how scarce training resources have become—few blog posts, tutorials, or open-source projects exist compared to web or mobile development. They also noted that while desktop app development was a solid career path in the 90s, it's now seen as a dead end for most, outside of big players like Microsoft or Adobe.This got me thinking: My own experience with desktop development dates back to the late 90s using Turbo Pascal 6 in Delphi, and I'm out of the loop on modern practices. With the evolving landscape, I'm curious about what tools and workflows developers are actually using today.Some questions to spark discussion:- What programming languages and frameworks are popular for desktop apps? - Are there any go-to IDEs, build tools, or libraries that make development easier? - Do the above answers change if you care about code performance or efficienc
The Prompt-Intent Gap: Why We're All Bad at Talking to AIIMAGE

The Prompt-Intent Gap: Why We're All Bad at Talking to AILast month, I watched my colleague spend 3 hours trying to get ChatGPT to write a simple technical blog post. He kept tweaking his prompts, adding details, removing details, changing tone. Nothing worked. That's when it hit me: we're all terrible at writing prompts, and we don't even realize it. The Hidden Problem Nobody Talks About Here's what I discovered after analyzing hundreds of prompts from our team: when we write prompts, our brains do this weird thing where we assume the AI knows what we know. We write "create a marketing strategy" when we really mean "create a B2B SaaS marketing strategy focusing on developer communities with a $10k monthly budget targeting series A startups." But it gets worse. Even when we try to be specific, we dump everything into one giant paragraph. No structure. Just a stream of consciousness that confuses any system. I tracked how much time our 15-person startup was losing to bad prompts: roughly 100+ hours per month of iterations and rewrites. The Ex

Show HN: A Modular Phoenix SaaS Starter KitIMAGE

Show HN: A Modular Phoenix SaaS Starter KitStarting a new SaaS project with Phoenix is a genuinely fantastic experience, as anyone who's dived into it will tell you. The framework itself is robust, performant, and a joy to work with. However, as I've been building out my own SaaS ventures, I've noticed a recurring pattern: no matter how brilliant Phoenix is, you inevitably find yourself configuring the same fundamental aspects time and time again. Setting up authentication, user management, payment gateways, and all the essential plumbing feels like a familiar, if slightly tedious, ritual.That's precisely why I developed the Phoenix SaaS Kit. It's designed to eliminate that repetitive setup, letting you hit the ground running with a solid foundation. The beauty of it is its modularity – you can cherry-pick the features you actually need for your specific project. So, while Phoenix gives you the incredible power to build amazing software, my kit offers a shortcut, freeing you from the boilerplate configuration and letting you fo

Show HN: Mochia, a virtual pet browser game, built with Rust, SolidJS, PostgresAround three years ago, I was reminiscing about how much I loved playing Neopets as a kid. Meanwhile, I was also looking for a project to better learn Rust and SolidJS. So.. I figured making my own virtual pet browser game would be a fun way to practice! Since then, I’ve been working on it nearly every day, and.. it’s grown quite a bit! Here are some bulleted lists for your convenience:Technical Details: * Backend monolithic Rust server runs on a single $5/month VPS * Lean frontend with just 3 dependencies (SolidJS, Solid Router, and Mutative) * Around 130,000 combined lines of code (frontend + backend) * Rust server uses axum, sqlx, tokio, rand, strum, tungstenite (websockets) * No server crashes or data loss in 3 years (thank you Rust + Postgres!) * Almost all graphics (500+ assets) are SVGs for perfect detail at every zoom level * Fully mobile responsive and playable on all modern browsers and devices * Actor model for player actions enables trivial parallel, multi-core scaling * Si
