[Other] Show HN: A Lisp for code generation and metaprogramming in non-Lisp languages Antilisp is a Lisp designed for code generation in non-lisp languages. The interpreter is written in RPython, and the language is designed for easy adoption by non-lispers. The project is still young, but the language can be played with if you don&#x27;t mind missing some important features like modules and pattern matching.<p>I have not published the source code yet, because I am not completely sure how to base a sustainable business on this project and I don&#x27;t want to risk having to rugpull after raising expectations.

[IDE/Editor] APKLab: Android Reverse-Engineering Workbench for VS Code

[Other] Show HN: A Raycast-compatible launcher for Linux Hey HN!<p>I&#x27;m a huge fan of Raycast, but as a Linux user, I was always disappointed it wasn&#x27;t available on my main OS. This summer, I decided to just build it myself. This project has the goal of being interoperable with Raycast itself, including a majority of the extensions.<p>It&#x27;s built with Tauri and Rust on the backend, with a Svelte frontend. The biggest challenge was getting it to run existing Raycast extensions, which required building a custom React renderer as well as making a custom API.<p>I also wrote a quick post, which I hope to expand on in the future, about this project. You can find it here: <a href="https:&#x2F;&#x2F;byteatatime.dev&#x2F;posts&#x2F;recreating-raycast" rel="nofollow">https:&#x2F;&#x2F;byteatatime.dev&#x2F;posts&#x2F;recreating-raycast</a><p>The project is still very rough, but I&#x27;m sharing it now to get any feedback you may have!

[Other] Show HN: BloomSearch – Keyword search with hierarchical bloom filters Hey HN! I got nerd-sniped by Bloom Filters this weekend, specifically for searching datasets with high &quot;cardinality&quot; (number of unique items).<p>They&#x27;re an _amazing_ data structure that, at a fixed size, tracks potential set membership. That means unlike normal b-tree indexes, they don&#x27;t grow with the number of unique items in the dataset.<p>This makes them great for &quot;needle in a haystack&quot; search (logs, document) as implementations like VictoriaMetrics and Bing&#x27;s BitFunnel show. I&#x27;ve used them in the past, but they&#x27;ve never been center-stage in my projects.<p>I wanted high cardinality keyword search for ANOTHER project... and, well, down the yak-shaving rabbit hole we go!<p>BloomSearch brings this into an extensible Go package:<p>- Very memory efficient via bloom filters and streaming row scans<p>- DataStore and MetaStore interfaces for any backend (can be same or separate)<p>- Hierarchical pruning via partitions, minmax indexes, and of course bloom filters<p>- Search by field, token, or field:token with complex combinators<p>- Disaggregated storage and compute for unbound ingest and query throughput<p>And of course, you know I had to make a custom file format ^-^ (FILE_FORMAT.MD)<p>BloomSearch is optimized for massive concurrency, arbitrary cardinality and dataset size, and super low memory usage. There&#x27;s still a lot on the table too in terms of size and performance optimizations, but I&#x27;m already super pleased with it. With distributed query processing I&#x27;m targeting &gt;100B rows&#x2F;s over large datasets.<p>I&#x27;m also excited to replace our big logging bill ~$0.003&#x2F;GB for log storage with infinite retention and guilt-free querying :P

[CLI Tool] Show HN: c0admin – A terminal-based AI assistant for Linux sysadmins I made a small CLI tool called `c0admin`. Runs locally using your own Gemini API key. No signup, no server, no tracking.<p>You just run `c0admin` in your terminal, and it gives you suggestions interactively.

[IDE/Editor] Show HN: VS Code extension to edit the filesystem like a text buffer This is a spiritual adaptation of oil.nvim for vscode. The main idea is you edit the filesystem by editing the current directory listing&#x27;s text buffer. For example, if I want to rename a file, I just rename it in the listing file. This is extremely powerful because it translates all of your text-editing skills immediately into file editing capabilities.<p>Some features:<p>* Create&#x2F;rename&#x2F;move&#x2F;delete files by editing the current directory listing&#x27;s textbuffer<p>* Filter using glob pattern<p>* Trash and undo support<p>* Works even in remote-ssh workspaces<p>* Works across multiple vscode windows

[Other] Show HN: HNping 'remind me later' for HN via web push HNping lets you set a reminder for a HN post. You get a web push browser notification when it&#x27;s time, and clicking it takes you back to the post. That&#x27;s it.<p>I built HNping because I kept stumbling on HN posts where the discussion still had to get going. Wanted to revisit, but didn&#x27;t want to create even more bookmarks&#x2F;etc I&#x27;ll just forget about. So I created a &#x27;remind me later&#x27; tool (like the reddit bot) to fix this for myself.<p>To use it: go to hnping.com, enable notifications, and drag the bookmarklet to your bookmarks bar. Then click it on any HN post to set a reminder (5 minutes to 1 week). No personal info needed - you just get a UUID that serves as your account.<p>I tried to make it as simple as possible.<p>It&#x27;s built on a Cloudflare Worker with D1 for data storage and uses Firebase Cloud Messaging for push notifications.

[Other] Show HN: We developed an AI tool to diagnose car problems Hey HN,<p>We built AutoAI – an AI tool that tells you what&#x27;s wrong with your car in plain English.<p>Just enter:<p>Your car’s make&#x2F;model&#x2F;year<p>The OBD2 error codes (optional) (like P0420, P0171, etc.)<p>Any symptoms you&#x27;re noticing (e.g. “rough idle” or “weird sound when starting”)<p>And we’ll tell you:<p>The most likely issue<p>How to verify it yourself<p>Whether it’s a DIY fix or shop-worthy<p>No more endless Googling or forum-hopping. Built for car owners, tinkerers, and pros who want fast, reliable answers. Powered by a repair-trained AI using real-world automotive data.<p>We’re trying to make diagnostics smarter, not replace your mechanic – just make you way more informed before spending money.<p>Would love feedback or crazy edge-case inputs to improve it.
