Show HN: I'm an airline pilot – I built interactive graphs/globes of my flights Hey HN!<p>Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history.<p>This globe is probably my favourite so far: <a href="https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all" rel="nofollow">https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all</a><p>If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

Show HN: Sink – Sync any directory with any device on your local network i made sink. it&#x27;s a simple little tool that continuously syncs folders between 2 devices. no cloud, no email, flash drives, no bs.<p>it just uses your local wifi. run it on your machines, tell them to trust each other, and you&#x27;re set. and if you manage to edit the same file at once, it handles the conflict and saves both copies.<p>for anyone who just wants to get files from point a to b without the headache. hope it makes your life a bit less annoying.<p>github: <a href="https:&#x2F;&#x2F;github.com&#x2F;sirbread&#x2F;sink">https:&#x2F;&#x2F;github.com&#x2F;sirbread&#x2F;sink</a> binary: <a href="https:&#x2F;&#x2F;github.com&#x2F;sirbread&#x2F;sink&#x2F;releases&#x2F;tag&#x2F;v0.1">https:&#x2F;&#x2F;github.com&#x2F;sirbread&#x2F;sink&#x2F;releases&#x2F;tag&#x2F;v0.1</a>

[Testing] Show HN: Magnitude – Open-source AI browser automation framework Hey HN, Anders and Tom here. We had a post about our AI test automation framework 2 months ago that got a decent amount of traction (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43796003">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43796003</a>).<p>We got some great feedback from the community, with the most positive response being about our vision-first approach used in our browser agent. However, many wanted to use the underlying agent outside the testing domain. So today, we&#x27;re releasing our fully featured AI browser automation framework.<p>You can use it to automate tasks on the web, integrate between apps without APIs, extract data, test your web apps, or as a building block for your own browser agents.<p>Traditionally, browser automation could only be done via the DOM, even though that’s not how humans use browsers. Most browser agents are still stuck in this paradigm. With a vision-first approach, we avoid relying on flaky DOM navigation and perform better on complex interactions found in a broad variety of sites, for example:<p>- Drag and drop interactions<p>- Data visualizations, charts, and tables<p>- Legacy apps with nested iframes<p>- Canvas and webGL-heavy sites (like design tools or photo editing)<p>- Remote desktops streamed into the browser<p>To interact accurately with the browser, we use visually grounded models to execute precise actions based on pixel coordinates. The model used by Magnitude must be smart enough to plan out actions but also able to execute them. Not many models are both smart *and* visually grounded. We highly recommend Claude Sonnet 4 for the best performance, but if you prefer open source, we also support Qwen-2.5-VL 72B.<p>Most browser agents never make it to production. This is because of (1) the flaky DOM navigation mentioned above, but (2) the lack of control most browser agents offer. The dominant paradigm is you give the agent a high-level task + tools and hope for the best. This quickly falls apart for production automations that need to be reliable and specific. With Magnitude, you have fine-grained control over the agent with our `act()` and `extract()` syntax, and can mix it with your own code as needed. You also have full control of the prompts at both the action and agent level.<p>```ts<p>&#x2F;&#x2F; Magnitude can handle high-level tasks<p>await agent.act(&#x27;Create an issue&#x27;, {<p><pre><code> &#x2F;&#x2F; Optionally pass data that the agent will use where appropriate data: { title: &#x27;Use Magnitude&#x27;, description: &#x27;Run &quot;npx create-magnitude-app&quot; and follow the instructions&#x27;, }, </code></pre> });<p>&#x2F;&#x2F; It can also handle low-level actions<p>await agent.act(&#x27;Drag &quot;Use Magnitude&quot; to the top of the in progress column&#x27;);<p>&#x2F;&#x2F; Intelligently extract data based on the DOM content matching a provided zod schema<p>const tasks = await agent.extract(<p><pre><code> &#x27;List in progress issues&#x27;, z.array(z.object({ title: z.string(), description: z.string(), &#x2F;&#x2F; Agent can extract existing data or new insights difficulty: z.number().describe(&#x27;Rate the difficulty between 1-5&#x27;) })), </code></pre> );<p>```<p>We have a setup script that makes it trivial to get started with an example, just run &quot;npx create-magnitude-app&quot;.

[Other] Show HN: AGL a toy language that compiles to Go I spent the past 2 weeks making this toy programming language.<p>I basically forked the Go scanner&#x2F;parser, and changed the syntax to have functions return a single value. This enable proper Result&#x2F;Option type to be used as well as propagating errors with an operator.<p>I also wanted to have short &quot;type inferred&quot; anonymous functions to be able to use functions like Map&#x2F;Reduce&#x2F;Filter, without having to use 100 characters to specify the types.

Show HN: Oasis – An open-source, 3D-printed smart terrarium See the website for a demo video: <a href="https:&#x2F;&#x2F;oasis-terrarium.com" rel="nofollow">https:&#x2F;&#x2F;oasis-terrarium.com</a><p>This project is an enclosure for growing plants. Features include:<p><pre><code> - high-power LED lighting - a built-in water tank and mister - fans for airflow - temperature and humidity sensing - wi-fi connectivity and a web-based interface for control and monitoring (see https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;usage_guide&#x2F;#web-interface) </code></pre> The entire project is open-source:<p><pre><code> - electronics: designed in KiCad - 3D models: designed in CadQuery - software: written in Rust </code></pre> I initially started this project during COVID and built a working prototype using a Raspberry Pi and off-the-shelf parts. The first prototype worked, but was pretty rough. Several months ago, I picked up the project again and began a complete re-design. After two rounds of circuit board design and countless iterations of the 3D-printed parts, I&#x27;m finally happy with the results. Along the way I learned a lot about electronics design and fabrication, 3D modeling, and Rust.<p>Happy to answer any questions - thanks for checking it out!<p>Here are some direct links to parts of the project you may find interesting:<p><pre><code> - demo video: https:&#x2F;&#x2F;oasis-terrarium.com - detailed build guide with pictures: https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;build_guide&#x2F; - interactive 3D model: https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;3dmodel&#x2F; - detailed info on electronics design: https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;electronics&#x2F; - 3D-printable models: https:&#x2F;&#x2F;www.printables.com&#x2F;model&#x2F;1315117-oasis-smart-terrarium</code></pre>
