Show HN: Attagram, a tiny printer that gives kids a magical daily digest I’m building Attagram: a small printer that lives in the kitchen and prints a daily paper digest for kids.<p>The idea came from an emerging family dynamic I kept noticing. My daughters (A, 9 and J, 8) are becoming increasingly independent, but as parents, we hold an enormous amount of invisible state in our heads and phones: what day a project is due, who needs cleats, what&#x27;s for lunch, which kid has library day, what chores need to happen before screens, how many days until the camping trip, what Grandma wanted them to know, what changed after school, etc.<p>Kids live downstream of that system, and their experience of it is repetitive nagging:<p>&quot;Brush your teeth.&quot; &quot;Pack your folder.&quot; &quot;Don&#x27;t forget your cleats.&quot; &quot;Don’t forget your water bottle.&quot; &quot;Did you pack your cleats?&quot; &quot;Please pack your cleats.&quot;<p>Even if the tone is kind, the repetition makes it feel like a nag. And all of the information is trapped behind screens, which isn&#x27;t great if you&#x27;re trying to limit your kids&#x27; screen time, all while trying to give them more ownership in the process.<p>Attagram tries solve for that. It turns that invisible family state into a small daily artifact a kid can own.<p>Every morning, the printer wakes up and prints a parent-curated morning edition newspaper. It has sections like: today’s plan, a todo list, a countdown to an event, a joke, a riddle, a note from a grandparent, and lots more. It&#x27;s something kids can tear off, pin to their bulletin board, shove in their pocket, or punch through a spike.<p>All of this is managed through, yes, an app. BUT! The app is for the parents. Its job is to be the best in the world at turning family logistics, rituals, and affection into a screen-free paper experience. The paper remains the hero, and how a kid experiences Attagram.<p>Technically, Attagram is pretty simple. It uses off-the-shelf parts to connect to a cloud service so daily digests can be generated and printed at scheduled times. It also allows trusted family members to send one-off notes as needed. The magic is in the experience overall and how it feels to hold the paper in your hands.<p>This is my first hardware project, and as a software person, I have really appreciated (and respected) how much there is to learn. It&#x27;s a lot of work to make sure this product is perfect on day one, because there&#x27;s no easy way to update hardware. Software is so forgiving!<p>We have a nationwide private beta program in homes now, and the feedback has been really positive. More than one family has told me that their kids park themselves in front of the printer each morning, waiting for it to print at the scheduled time. I&#x27;m planning to ship a few more units for free to really ensure we&#x27;re getting all the input we can before going into more scaled production. If you think you&#x27;d be interested in one, drop me a line at myke@halfcorp.co.<p>Our modest plan is to reach 100 paid reservations before scaling manufacturing, partly to test whether strangers actually want this enough to pay rather than just say &quot;cute idea.&quot; <a href="https:&#x2F;&#x2F;www.attagram.com&#x2F;order" rel="nofollow">https:&#x2F;&#x2F;www.attagram.com&#x2F;order</a><p>I’d value HN&#x27;s experience on:<p>1. Industrial design: what stands out as being &quot;bad design&quot; in the current iteration? Also, if this is something you&#x27;d want to work on, I&#x27;d love to chat!<p>2. Mechanical engineering: what are the best ways to &quot;harden&quot; a device like this so it&#x27;s reliable, but easy to manufacture. Also, if this is something you&#x27;d want to work on, I&#x27;d love to chat!<p>3. Manufacturing: when do you engage with a contract manufacturer in China? What do you try to avoid? Also, if this is something you&#x27;d want to work on, I&#x27;d love to chat!<p>4. HN Parents: is this something you could see yourself buying, or it just cute? If the former, but you wouldn&#x27;t pre-order, why not?

Show HN: Relaymux, a tmux-based meta-harness for local coding agents Hey HN,<p>There’s been a lot of interest recently in meta-harnesses, loops, and multi-agent orchestration. Obviously, there are already a lot of good tools: Conductor, cmux, the native Codex &#x2F; Claude Code apps, etc.<p>For my own use cases, I’ve felt that the orchestration layer tends to feel overengineered. I mostly wanted a simple local harness (i.e Pi) for running and tracking CLI agents with the ability to hop in (via tmux). Relaymux is my opinionated attempt at that.<p>A few design principles:<p>- The frontend is just Telegram &#x2F; iMessage &#x2F; CLI. If I want more visibility, I hop into tmux.<p>- Subagents are normal interactive CLI agents running in tmux windows, usually with their own worktrees.<p>- The harness owns the tmux session, so each longer task becomes a named tab&#x2F;window. Subagents report back to the orchestrator via CLI when they’re blocked or done. Then the orchestrator just messages me on Telegram &#x2F; iMessage<p>- It works with any CLI agent that has an interactive terminal mode, so I don’t need special print-mode&#x2F;non-interactive support. This means I don’t need to stress about the Agent SDK &#x2F; claude -p billing limitations.

Show HN: An 8-bit live gamecast for baseball Hey HN, I built a website to watch live baseball games in an 8-bit broadcast. It takes live MLB data streams and converts them into near real-time pixel art gamecasts.<p>Been waiting to share this for when there’s actually a good slate of games happening since the site is pretty bare otherwise.<p>Here is today&#x27;s schedule:<p>Mets @ Reds - 9:40am PDT <a href="https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;824503" rel="nofollow">https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;824503</a><p>Royals @ Nationals - 10:05am PDT <a href="https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;822721" rel="nofollow">https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;822721</a><p>Marlins @ Phillies - 10:05am PDT <a href="https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;823450" rel="nofollow">https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;823450</a><p>Tigers @ Astros - 11:10am PDT <a href="https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;824178" rel="nofollow">https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;824178</a><p>Padres @ Cardinals - 11:15am PDT <a href="https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;823044" rel="nofollow">https:&#x2F;&#x2F;ribbie.tv&#x2F;watch&#x2F;game&#x2F;823044</a><p>..and another 14 games throughout the later day.<p>I&#x27;m still early on in this project, but I&#x27;ve tried to add little details with actual stadiums, day and night modes, between inning graphics and interstitials, live scoreboards, etc.<p>Would love any feedback and ideas. Thanks for checking it out!

Show HN: Vpod – Tiny Linux sandbox running in WASM Hi HN,<p>I spent the last few months reading the RISC‑V specification to build the lightest possible sandboxes. The idea behind a vpod is to quickly spin up a Linux sandbox from snapshots (Alpine by default) without any setup or subsystem required.<p>The trade-off for portability and security is raw CPU speed. So we don&#x27;t expect it to match native workloads with Python or pip, for example.<p>More info is in the README <a href="https:&#x2F;&#x2F;github.com&#x2F;capsulerun&#x2F;vpod" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;capsulerun&#x2F;vpod</a><p>Happy to answer any questions!

Show HN: In-browser Python/Pandas/Git practice with animated Git simulator I&#x27;ve created an in-browser Python&#x2F;Pandas&#x2F;Git practice environment for my online learning platform and also for my corporate training classes. I&#x27;d be happy to discuss how I went about designing this, how I&#x27;m using it in my classes, and the architectural decisions I&#x27;ve made.<p>Most interesting, to me, is how much is running in the browser. Thanks to Svelte, Pyodide, isomorphic-git, LightningFS, and CodeMirror I&#x27;m able to provide a full environment for Python, Pandas, and Git.<p>I built much of this with Claude Code, and I&#x27;m happy to discuss how that went — what worked well and where I had to step in and make the calls myself.<p>I&#x27;m especially excited about the Git simulator: it shows the commit tree change as you run commands, plus an animated view of how files move between the working tree, the staging area, and HEAD.<p>The AI tutor, which uses Claude Haiku, was given my newsletters, classes, and exercises as inputs, along with a description of my pedagogical approach: instructors should give hints and feedback, but not reveal the answer.
