[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.

[CLI Tool] Show HN: Wosp – advanced full-text search on the command line Hi, I&#x27;m Andrew Trettel. I&#x27;m a scientist and researcher. I wrote Wosp to help me search local documents using Boolean and proximity operators.<p>Wosp is a command-line program that performs full-text search on text documents. Wosp stands for word-oriented search and print. It is designed for advanced searchers. It works differently than line-oriented search tools like grep, so it can search for matches spanning multiple lines. Wosp supports an expressive query language that contains both Boolean and proximity operators. It also supports nested queries, truncation, wildcard characters, and fuzzy searching.<p>The linked GitHub repository contains all of the code to try out the program. I also wrote a blog post (<a href="https:&#x2F;&#x2F;www.andrewtrettel.com&#x2F;blog&#x2F;wosp&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.andrewtrettel.com&#x2F;blog&#x2F;wosp&#x2F;</a>) that discusses my motivations for creating Wosp in more detail, along with some additional technical discussion and diagrams.<p>If you give Wosp a try, I&#x27;d appreciate any comments or feedback you have about the experience.
