[Other] Show HN: I built a search engine for all domains on the internet Hi HN,<p>I built DomainExplorer.io, a search and analytics tool that lets you explore newly registered and expired domains across all TLDs — updated daily.<p>The idea came from my frustration how hard it is to search for registered&#x2F;expired domains. I wanted a simple and easy-to-use tool with web UI where you could submit queries like:<p>- Find all domains in .com and .net zones that end with &quot;chatgpt&quot;.<p>- Find all expired domains that have &quot;copilot&quot; substring in name (excluding .ai and .io zones) and their name is shorter than 12 symbols<p>- Find all domains with &quot;amazon&quot; in name and that were created earlier than June 20, 2023<p>But there was nothing like that around.<p>So I decided to built this tool myself.<p>DomainExplorer.io currently indexes 300M+ active domains from 1,500+ zone files, refreshed daily. You can filter by TLD (zone), name length, active or expired, substring or patterns (e.g. “starts with best”, “ends with copilot”, &quot;contains chatgpt&quot;), and download the results as CSV or JSON.<p>Tech stack: Go, PostgreSQL, React&#x2F;TypeScript, hosted on baremetal server (cloud is way too expensive for me for such a project), and a custom search index that I designed and built myself because ElasticSearch&#x2F;Lucene were either too slow or excessively packed with features that I did not need. As a result, I&#x27;ve built pretty lean and performant search engine for domains, you literally get results within 1-2 seconds across all 300M domains search.<p>I’d love your feedback — especially around use cases I might be missing (security research, trend tracking, brand monitoring, etc.) and any ideas for making search faster or more useful for developers.<p>Please give it a try!<p><a href="https:&#x2F;&#x2F;domainexplorer.io" rel="nofollow">https:&#x2F;&#x2F;domainexplorer.io</a>

[Other] Show HN: Dynamic code and feedback walkthroughs with your coding Agent in VSCode I&#x27;ve been programming since I&#x27;m 6 and I don&#x27;t want to quit. Since Agents came into existence I&#x27;ve been increasingly building more of the random ideas.<p><i>BUT, like many</i> I kept getting stuck and frustrated where I wanted to make changes with the Agent that I <i>knew</i> I could&#x27;ve made without it but I had *no clue* how things worked.<p>I created Intraview to help me build and maintain a mental model of what I was building (or had vibed) so I could use my knowledge to either fix it myself, or provide more directed instruction. It grew into something that&#x27;s transformed my workflow in a pleasant way.<p>Intraview is a VS Code extension that allows you to create: - Dynamic code tours built by your existing Agent - Storage and sharing of tours (it&#x27;s a file) - Batch Feedback&#x2F;commenting inline in IDE in-tour and without (it&#x27;s also a file)<p>Here&#x27;s a video walkthrough for the show vs tell crowd where I jump in a random (<i>Plotly JS</i>) open source repo and build a tour to get started: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=ROBvFlG6vtY" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=ROBvFlG6vtY</a><p>Talking tech design, this is very different than most because the whole App is cloudless. Not server less, there&#x27;s no external APIs (outside basic usage telemetry).<p><pre><code> - basic TypeScript app, JS&#x2F;CSS&#x2F;HTML - Localhost MCP server inside VS Code (one per workspace open) </code></pre> Three of the biggest challenges I faced was:<p><pre><code> - re-considering the user experience given there&#x27;s no database - trying to build a reasonable experience to manage MCP connection across so many different setups. - testing the many forks, Agents and themes because I wanted to make it look native (I&#x27;ll probably reverse course here in future iterations) </code></pre> What I&#x27;m curious about is, where do you see the value:<p><pre><code> - New project&#x2F;developer onboarding - PR reviews - Keeping up with Agentic code - Perf reviews (for EM), you could build a tour biggest contributions by a GitHub handle - Planning alignment and review with your Agent </code></pre> You can see the extension page in VS Code with these custom links <i>(Note: this redirects and requires permission to open VS Code, won&#x27;t actually install, takes another click)</i><p><pre><code> - for VS Code: https:&#x2F;&#x2F;intraview.ai&#x2F;install?app=vscode - for Cursor: https:&#x2F;&#x2F;intraview.ai&#x2F;install?app=cursor </code></pre> Once it&#x27;s installed and you confirm MCP is connected to your local server, just ask your Agent:<p><pre><code> - Create an Intraview the onboarding for this app.. - Let&#x27;s use Intraview to gather my feedback on [whatever you created]. Break down steps such that I can provide good granular feedback. </code></pre> Looking forward to your feedback and discussion.<p>And because this is HN. A relevant quotable from PG.<p><pre><code> “Your code is your understanding of the problem you’re exploring. So it’s only when you have your code in your head that you really understand the problem.” — Paul Graham</code></pre>

[CLI Tool] Show HN: qqqa – a fast, stateless LLM-powered assistant for your shell I built qqqa as an open-source project, because I was tired of bouncing between shell, ChatGPT &#x2F; the browser for rather simple commands. It comes with two binaries: qq and qa.<p>qq means &quot;quick question&quot; - it is read-only, perfect for the commands I always forget.<p>qa means &quot;quick agent&quot; - it is qq&#x27;s sibling that can run things, but only after showing its plan and getting an approval by the user.<p>It is built entirely around the Unix philosophy of focused tools, stateless by default - pretty much the opposite of what most coding agent are focusing on.<p>Personally I&#x27;ve had the best experience using Groq + gpt-oss-20b, as it feels almost instant (up to 1k tokens&#x2F;s according to Groq) - but any OpenAI-compatible API will do.<p>Curious if the HN crowd finds it useful - and of course, AMA.

[Other] Show HN: sudocode – manage specs, tasks, and context-as-code for coding agents sudocode is a lightweight context management system for coding agents that lives in your repo. It helps organize the chaos of human-AI collaboration by capturing user intent as durable specs and tracking agent activity as issues, all version-controlled with Git. This &quot;context-as-code&quot; approach reduces agent amnesia and accelerates development on long-horizon tasks.

[Other] Show HN: Cj–tiny no-deps JIT in C for x86-64 and ARM64 Hey y’all!<p>About 7 years ago, I had this idea to write a JIT with an autogenerated backend for x86 based on the ISA specs. I sketched something out and then just kinda let it sit. I picked it up again a few weeks ago and made a complete-ish backend for both x86 and ARM64. It has no dependencies, the backends are completely autogenerated (by horrible, horrible JS scripts), and I built a small abstraciton layer for things like functions prologues etc.<p>It’s super duper early and will probably break on your machine, but it’s good enough to compile some cool examples (look at the examples directory: <a href="https:&#x2F;&#x2F;github.com&#x2F;hellerve-pl-experiments&#x2F;cj&#x2F;tree&#x2F;master&#x2F;examples" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;hellerve-pl-experiments&#x2F;cj&#x2F;tree&#x2F;master&#x2F;ex...</a>, my personal favorite is the minimal language implementation: <a href="https:&#x2F;&#x2F;github.com&#x2F;hellerve-pl-experiments&#x2F;cj&#x2F;blob&#x2F;master&#x2F;examples&#x2F;minilang.c" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;hellerve-pl-experiments&#x2F;cj&#x2F;blob&#x2F;master&#x2F;ex...</a>).<p>It doesn’t have anything except basically a fancy JIT assembler with some helpers as of yet. No register allocator, a lot of ABI details will still have to be figured out manually (though of course feel free to add anything to the abstraction layer that’s generally useful and submit a PR!).<p>I honestly don’t know where I’m going with this next. I kind of stumbled into the project, and am not sure whether I’ll consider it as “exercise completed” or whether I should pursue it more. Time will tell.<p>Feedback, questions, and bug reports very welcome—especially on the codegen helpers, additional examples or cool things you come up with, or backend rough edges.<p>P.S.: I also wrote a small announcement blog post on it that you can find here (<a href="https:&#x2F;&#x2F;blog.veitheller.de&#x2F;cj:_Making_a_minimal,_complete_JIT.html" rel="nofollow">https:&#x2F;&#x2F;blog.veitheller.de&#x2F;cj:_Making_a_minimal,_complete_JI...</a>), but it honestly doesn’t add all that much interesting info that you can’t find in the repo.
