Ask HN: Encouraging a child's gaming PC build despite fear of gaming addiction?https://news.ycombinator.com/item?id=4826332112yo son is doing dedicated research on gaming PC parts and binge-watches videos on how to build (he's not a native English speaker and has no real electronics skills, so this is quite impressive tbh). Me the dad, however, fears that I'm witnessing a FPS addict being born.What's a good Middle Way here? Kid actually building the machine all by himself -- 100% yes, even if it's quite expensive; kid then Counter Striking, Call of Dutying etc for hours on dat 27" screen -- ugh!What complicates things is that I myself am more of a "computational minimalist" using 15 year old machines in a cli-only environment etc. I've tried to show him That Path also ("dude, here's some Turbo Pascal for ya!"), but, well, obviously he's preferring those addictively engineered and GPU-hungry multiplayer games with his friends any day.He's a good kid all in all, actively engaged in competitive rowing, with good grades etc. Plays chess also (but all the other folks are FPSing or Minecrafting, so there's that).May 25, 2026 4:11 AM

Show HN: Objo Studiohttps://objo.devObjo Studio is a new development environment for building desktop and command line apps. It has a visual designer, a debugger, a compiler, and a modern BASIC-like language called ObjoBasic. The aim is simple: make it enjoyable to build real applications for macOS, Windows and Linux and learn how to program.I've been working on Objo Studio in one shape or another since about 2019. I've always loved tools that let you move quickly from idea to working prototype and that abstract a lot of complexity and get out of your way. This has been tried before (VisualBasic, Xojo, etc) but have either been abandoned, become expensive or lost focus on hobbyists.The whole stack is written in C#. There's a custom stack-based VM that is roughly on-par with Python for speed but this is not a high performance tool. It's an all-in-one IDE for visually developing cross-platform desktop apps. It tries to make it simple for users, abstracting runtimes and libraries to help newcomers learn but also let them thMay 11, 2026 3:38 PM

Man tar why we use -fhttps://news.ycombinator.com/item?id=47995364Device selection and switching -f, --file=ARCHIVE Use archive file or device ARCHIVE. If this option is not given, tar will first examine the environment variable ‘TAPE'. If it is set, its value will be used as the archive name. Otherwise, tar will assume the compiled-in default. The default value can be inspected either using the --show-defaults option, or at the end of the tar --help output. An archive name that has a colon in it specifies a file or device on a remote machine. The part before the colon is taken as the machine name or IP address, and the part after it as the file or device pathname, e.g.: --file=remotehost:/dev/sr0 An optional username can be prefixed to the hostname, placing a @ sign between them. By default, the remote host is accessed via the rsh(1) command. Nowadays it is common to use ssh(1) instead. You can do so by giving the following command line option: --rsh-command=/usr/bin/ssh The remote machine should have the rmt(8) command installed. If its pathname doMay 3, 2026 10:06 AM

Show HN: SimFic – A multi-agent narrative simulation for interactive fictionhttps://simfic.netHello HN,I'd like to share a hobby project I'm working on called SimFic: a multi-agent interactive fiction simulation engine. Many of you like to read. But have you wanted to do more than just follow through someone's story? What if you could step into their shoes, and play it out yourself in a simulated environment?The problem: simply prompting an AI chatbot (e.g. ChatGPT) directly with a world/story-building prompt and expecting a rich, non-linear output is fundamentally flawed; in the real world, information asymmetry, Theory of Mind, non-determinism, etc. affect how people think and act. Asking a single LLM like ChatGPT to mentally simulate these constraints is flawed because of Transformer attention, as it is omniscient by technical design. Furthermore, LLMs are heavily tuned to be helpful and finish things early. If you've tried writing a book with an LLM, you know that the result is laughably short and shallow. If we use an LLM as-is, every action will succeed, every path will bMar 27, 2026 3:07 PM

Show HN: Lukan – An open-source agentic workstation in a single Rust binaryhttps://lukan.aiHi HN, I've been building Lukan, an open-source (MIT) agentic workstation that runs entirely as a single Rust binary with zero runtime dependencies. I started this because I wanted a unified workstation optimized for my own productivity. My goal was to build an environment where I could securely remote into my machine from anywhere, seamlessly view and modify local files, and run AI agents or drop into a terminal side-by-side, all integrated with a rich set of built-in tools. Here is what makes it different: Multi-agent sessions: Run multiple agents in parallel, each with its own isolated context and history. You can switch between them using tabs, resume after disconnects, and even rewind to previous checkpoints. Embedded terminal: A full tmux-backed terminal lives inside the Web and Desktop UI. Sessions survive page reloads and network drops. You can run any CLI tool alongside your agent (including Claude Code, Codex CLI, Lukan Cli, etc.).

Ask HN: AI Agents vs. Gateways vs. Harnesseshttps://news.ycombinator.com/item?id=47397737Hi,I'd like to get everyone's take on the different components in the AI Agents ecoysystem. I find the current terminology quite confusing as it's not always obvious what I'll be actually getting when I examine the available options.A lot of things get called Agents, but that term seems hard to define as it often refers to overlapping functionality. To me, agents seem to be currently composed of the following components:## Harnesses- Adds UI and system instructions around an LLM and may also augment it with tools such as memory, tool calls, etc...- Examples are Claude Code, Code, Gemini CLI, pi.dev, ...## Gateways- These connect agents to your communication tool of choice, e.g. Whatsapp, Telegram, Slack, Discord, ...- Examples are OpenClaw and Nanoclaw## Sandboxes- Isolated environments where Agents can run with limited or auditable capabilities- Examples can be from physical ones like separate Mac Minis to docker-agent, agent-sandbox, localsandbox, ...This then takes us to *Agents*:##Mar 16, 2026 11:43 AM

And this project is based here(https://github.com/ufo5260987423/scheme-langserver).I built it because I was tired of Scheme/Lisp's raggy development environment, especially of the lack of IDE-like highly customized programing experience. Though DrRacket and many REPL-based counterparts have don't much, following general cases aren't reach same-level as in other modern languages: (let* ([ready-for-reference 1] [call-reference (+ ready-for-)])) Apparently, the `ready-for-` behind `call-reference` should trigger an auto-complete option, in which has a candidate `ready-for-reference`. Besides, I also know both of them have the type of number, and their available scope is limited by `let*`'s outer brackets.
