Show HN: My 13-year-old built an ant colony tracker He's 13 years old. He wanted to track his own ant colonies — growth, feeding, humidity, and other metrics. He built the whole app himself with some help from AI tools; I just helped him deploy it to a server. Would love to hear your feedback!

Show HN: Curvytron 2, I rewrote my browser party game, 10 years later Hi everyone, french web dev here,<p>About 10 years ago I did a little party game in the browser inspired by Achtung die Kurve genre, it reached HN (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=9494619">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=9494619</a>) and everything went crazy, it&#x27;s still largely played in open-spaces all over the world today.<p>This past year, I&#x27;ve been working on a sequel: <a href="https:&#x2F;&#x2F;curvytron2.com" rel="nofollow">https:&#x2F;&#x2F;curvytron2.com</a> is live.<p>Same goal as the first one: challenge myself, perfect my skills, have fun and give back to the internet community the best way I know; by just putting a free little fun game out there. No ads, no tracking, no business plan.<p>A decade of professional web development and hours of GMTK have raised my expectations and this time I aimed for:<p>- a good looking top-down 3D view with improved gameplay and real game juice: I learn Three.JS and WebGL for this project, worked on the camera movements, screen shake, sound design, gameplay feedback and I&#x27;m proud of the portal-like effect of the bonus that allows you to peak and cross over to the other side of the map. - a solid 100fps server simulation (in Go) serving clients with a really bandwidth efficient netcode (it&#x27;s binary websocket instead of plain JSON and I open-sourced it: <a href="https:&#x2F;&#x2F;github.com&#x2F;Tom32i&#x2F;netcode" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Tom32i&#x2F;netcode</a>). - Instant reconnection, at any time: I had this requirement from day one, in the first curvytron losing connexion meant dropping out of the game permanently. Not anymore. You can just refresh the page mid-game and keep playing, try it yourself.<p>The game runs in any desktop and mobile browser and supports gamepads I&#x27;ve put up servers in US and Europe to offer a good ping to as much players as I can afford at the moment.<p>I still maintain and host the first game to keep the original experience live.<p>I&#x27;d love to get feedback from HN, and don&#x27;t hesitate to stress-test the game of course!<p>I&#x27;ll be around to answer questions and discuss if you&#x27;re interested. Cheers!

[DevOps] Show HN: ServerKit – A mobile UI for server management Problem Statement: A few months ago, I was outside of my city. I was on a bus when one of my team members messaged me saying users were unable to read the product description PDF. I had to wait 3 more hours until I got back home, opened the laptop, and SSH&#x27;d into the server to find out what was wrong. In that moment I realized that being able to manage a server from a phone is very important when a laptop is not nearby.<p>What it does: It is a UI wrapper over standard SSH command outputs. It parses the SSH output and shows the results in UI elements, and also translates your actions to relevant SSH commands. This way users won&#x27;t have to heavily rely on the command line – as we know, typing commands from a mobile device is also hard. However, it also has a terminal to allow you to do anything. It also supports Kubernetes, where you can see and manage pods, view logs and stats, and RDBMS to allow you to quickly perform database operations – a bit like phpMyAdmin or pgAdmin.<p>Tech Stack: Flutter, SSH, Android Secured Storage, Firebase, Docker<p>Why Android: I know – iOS is a major platform for this niche. But for now – as it is an MVP – I have decided to develop for Android to validate my idea and understand if it solves a real problem. The good news is, it does solve a real problem – at least the analytics say so. Within 30 days I got 5 premium users. About 30% of users connect their server and 23% of them use the app regularly. So now I am working on the iOS version.<p>Current Limitations: Currently the app only supports Ubuntu – other Debian based OSes are not tested, though they might work as well. The Kubernetes and AWS features need more testing. Also, ServerKit VPS Lab currently limits sessions to only 30 minutes TTL to prevent misuse.<p>Feedback Request: I would love your feedback on the VPS management and monitoring features, RDBMS features, and Kubernetes features. I also tried to keep the terminal simple, but your feedback on this is also valuable to me.<p>Try it out: If you don&#x27;t want to connect your own VPS, you can test the app using ServerKit Lab. It will allow you 30 minutes of free VPS to test the app. Install ServerKit: <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.iishanto.servermanager">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=com.iishanto.s...</a>

Show HN: C++, Java and C# light-weight-logger This is a library I&#x27;ve been working on with versions for C++, java &amp; C# where you make custom formats and Log based on them, for example you could make an ERROR Like this:<p><pre><code> [ERROR] [date, time-stamp, time-zone] &lt;main log message&gt; (file:thread-ID:line) </code></pre> but you would write it like this:<p><pre><code> &#x2F;&#x2F; define the master format master_style = &quot;%C[%N]%c%S%G[%D %T %Z]%c %M %G(%F:%t:%L)&quot;; &#x2F;&#x2F; tell the logger what colour to use for a given name logger.add_format(&quot;ERROR&quot;, master_style, Colour::RED); </code></pre> so now the [ERROR] part will be red, the time area will be grey, and the location grey, but you could really make any style you wanted. And once you have a master format you could also add different types of logs:<p><pre><code> logger.add_format(&quot;SUCCESS&quot;, style_minimal, Colour::GREEN); logger.add_format(&quot;INFO&quot;, master_style, Colour::CYAN); logger.add_format(&quot;WARN&quot;, master_style, Colour::YELLOW); </code></pre> also the %S we put in there is actualy a colum padder so you logs will be inline:<p><pre><code> [INFO] [16&#x2F;06&#x2F;2026 10:58:00 AUS Eastern Standard Time] Initializing core subsystem components. (src&#x2F;main.cpp:1:39) [SUCCESS][16&#x2F;06&#x2F;2026 10:58:00 AUS Eastern Standard Time] Database connection established smoothly.

[Monitoring/Observability] Show HN: TraceAIO – open-source LLM visibility tracker I built TraceAIO, an open-source tool that prompts LLMs on your behalf and tells you whether ChatGPT, Perplexity, and Gemini mention your brand — and which competitors and sources show up instead.<p>Yeah, this category smells a bit like a grift, same as early SEO. And I think over time it will become just SEO again, and become about good content. The tool just helps you monitor over time.<p>It queries the browser products through real browser sessions, not APIs, runs on Docker, with an MCP server so you can query your own data through an LLM.<p>No business model, Apache 2.0, self hosted. If you use a residential proxy instead of running the browser locally I get a few cents via referral, not even enough to cover my token costs.<p>Demo (no signup): <a href="https:&#x2F;&#x2F;demo.traceaio.org" rel="nofollow">https:&#x2F;&#x2F;demo.traceaio.org</a> — admin@example.com &#x2F; adminadmin<p>Code: <a href="https:&#x2F;&#x2F;traceaio.org" rel="nofollow">https:&#x2F;&#x2F;traceaio.org</a><p>Long on-and-off project, finally happy to show it.

Show HN: Running Gemma-4 26B at 124 tokens/SEC on a CPU, no GPU I wanted to know how fast a 26B mixture-of-experts model could run on a desktop CPU with no GPU. Got ~40 tok&#x2F;s single-stream (lossless) and ~124 batched. The surprising part was the byte budget: for this model you compress the output head (32% of per-token bytes), not the experts (16%). The writeup has the bandwidth roofline and the dead-ends; the repo has the reproducible recipe. Happy to answer questions.<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;arun-prasath2005&#x2F;gemma4-cpu-moe" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;arun-prasath2005&#x2F;gemma4-cpu-moe</a>
