[Other] Show HN: Semble – Code search for agents that uses 98% fewer tokens than grep Hey HN! We (Stephan and Thomas) recently open-sourced Semble. We kept running into the same problem while using Claude Code on large codebases: when the agent can&#x27;t find something directly, it falls back to grep, reading full files or launching subagents. This uses a lot of tokens, and often still misses the relevant code. There are existing tools for this, but they were either too slow to index on demand, needed API keys, or had poor retrieval quality.<p>Semble is our solution for this. It combines static Model2Vec embeddings (using our latest static model: potion-code-16M) with BM25, fused via RRF and reranked with code-aware signals. Everything runs on CPU since there&#x27;s no transformers involved. On our benchmark of ~1250 query&#x2F;document pairs across 63 repos and 19 languages, it uses 98% fewer tokens than grep+read and reaches 99% of the retrieval quality of a 137M-parameter code-trained transformer, while being ~200x faster.<p>Main features:<p>- Token-efficient: 98% fewer tokens than grep+read<p>- Fast: ~250ms to index a typical repo on our benchmark, ~1.5ms per query on CPU (very large repos may take longer)<p>- Accurate: 0.854 NDCG@10, 99% of the best transformer setup we tested<p>- MCP server: drop-in for Claude Code, Cursor, Codex, OpenCode<p>- Zero config: no API keys, no GPU, no external services<p>Install in Claude Code with: claude mcp add semble -s user -- uvx --from &quot;semble[mcp]&quot; semble<p>Or check our README for other installation instructions, benchmarks, and methodology:<p>Semble: <a href="https:&#x2F;&#x2F;github.com&#x2F;MinishLab&#x2F;semble" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;MinishLab&#x2F;semble</a><p>Benchmarks: <a href="https:&#x2F;&#x2F;github.com&#x2F;MinishLab&#x2F;semble&#x2F;tree&#x2F;main&#x2F;benchmarks" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;MinishLab&#x2F;semble&#x2F;tree&#x2F;main&#x2F;benchmarks</a><p>Model: <a href="https:&#x2F;&#x2F;huggingface.co&#x2F;minishlab&#x2F;potion-code-16M" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;minishlab&#x2F;potion-code-16M</a><p>Let us know if you have any feedback or questions!

[Other] Show HN: Got ghosted by tech companies so I built a tool to track ghost jobs Last year I was looking for a new role. I sent out applications, did the prep, waited. What came back was mostly nothing. Not rejection emails, just silence. The job listings I&#x27;d applied to stayed live for weeks. Some for months.<p>As a software engineer, I decided to dig into it properly. I built a system to continuously track job postings across companies, logging posting dates and measuring how long roles stay open before closing or don&#x27;t. After 35,000+ listings across 200+ companies, some patterns are hard to ignore. Some listings have been open for 700+ days at companies you&#x27;d recognize. Others post 90% of their open roles within a single month, a signal that&#x27;s harder to fake than a press release.<p>I published two initial insight pages based on this work: - Which companies are posting most aggressively right now - Job listings that have been open for over a year<p>What I didn&#x27;t expect is that the same signals useful for detecting ghost jobs also say something broader about a company&#x27;s hiring momentum, recruiting intensity, pipeline health, where talent bottlenecks might exist. I&#x27;m not sure yet where this leads, but I&#x27;ll keep expanding the dataset and publishing more insights as I go.<p>Would genuinely love feedback on the methodology, interpretation, or obvious blind spots in the data.

[CLI Tool] Show HN: Epiq – Distributed Git based issue tracker TUI Issue trackers typically live outside of your workflow, with poor ergonomics. Epiq aims to solve that, bringing issue tracking into your terminal. Multi-user collaboration is achieved via git using user-scoped immutable event logs that converge in memory. Put my all into it. Let me know what you think.

[CLI Tool] Show HN: MIT OSS LinkedIn DMs for Agents (CLI and Example TUI) I was tired of paying $100s&#x2F;mo to access data I should own -- my own DMs on social media -- so I built Allman, a local-first cli to access linkedin messenger.<p>Starting with LinkedIn, I gave the entire compiled js binary of linkedin&#x27;s web app to claudecode and reversed engineered the entire messenger inbox in 24 hours. My goal is to bring this to all messengers so AI can handle all of this busywork, just like it can my email.<p>I had also never built a TUI so I had claudecode build me one based on top of the local CLI and filesystem.<p>Full repos:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;tarkaai&#x2F;allman-cli" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tarkaai&#x2F;allman-cli</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;tarkaai&#x2F;allman-tui" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tarkaai&#x2F;allman-tui</a><p>Their sharding &#x2F; access is brutal, so it&#x27;ll likely break as-is -- but the point is that Reverse Engineering is trivial now (and can do it dynamically through browser access and dynamic playwright -- thanks Browserbase! ).<p>Would love to hear your feedback and what I should build on it next.<p>Shoutout to Eric Allman.

[Other] Show HN: Browser based sythesizer, drum machine and squencer Inspired by the recent Boards Of Canada announcement, I&#x27;ve been in a low-fi electronica mood lately and was going back and forth with Claude on how to design similar instruments in the browser that fit the genre. One thing led to another and pretty soon I had a fully browser based polyphonic synthesizer &#x2F; drum machine &#x2F; sequencer.<p>The interface and workflow was heavily inspired by the Rebirth338 application released back in the 90&#x27;s, but with lo-fi synth voices rather than the original 303 &amp; 808 emulation.<p>I know there&#x27;s a significant overlap of developers and musicians and I though some of you may enjoy playing with the app, or at least listening to the resulting album. I&#x27;ve also open sourced track 1 of the album via the performance script used to record it. It&#x27;s in the repo.<p>Bandcamp link to the resulting album: <a href="https:&#x2F;&#x2F;madmonk13.bandcamp.com&#x2F;album&#x2F;yesterdays-tomorrow-today" rel="nofollow">https:&#x2F;&#x2F;madmonk13.bandcamp.com&#x2F;album&#x2F;yesterdays-tomorrow-tod...</a>
