[Other] Show HN: Clippy – a better pbcopy for macOS that handles files properly I made clippy because pbcopy can&#x27;t do something I needed every day: copy files to paste into GUI apps. When you pbcopy &lt; image.png, you get raw bytes instead of a file that Slack or email can use.<p>Clippy fixes this:<p>- clippy report.pdf → ⌘V into any app uploads the file<p>- curl image.png | clippy → pipes become pasteable files<p>- clippy *.jpg → multiple files at once<p>- Text files still work like pbcopy<p>Technical: Direct Objective-C bindings via CGo. Copies file references (like Finder), not contents. Auto-cleans temp files. No AppleScript hacks.<p>Install: brew install neilberkman&#x2F;clippy&#x2F;clippy

[Other] Show HN: I built a dream interpreter in JavaScript, no AI, no server, just logic I built a browser-only dream interpreter that maps symbols to meaning using a custom keyword engine. No AI, no tracking, no backend it’s all deterministic logic, built with vanilla JavaScript. The idea was to see if emotional and symbolic interpretations could still feel personal without using machine learning. Dreams are parsed against a map of 300+ symbolic meanings. Everything runs locally in your browser and saves via localStorage. You can revisit old dreams, reflect on interpretations, or just explore what the system sees in your subconscious. Happy to answer questions, would love feedback!

[Other] Show HN: I built a tool to sync localStorage between devices At my day job, we have a daily async stand-up. We have to message a slack bot how many hours we have worked on a given task that day and overall.<p>The format is:<p>&gt; Task: &quot;Task Name&quot; | Worked: 5h Total: 16h &gt; Description: Finished implementation of feature.<p>I don&#x27;t complain. Most fully remote jobs come with a version of this, but doing it manually got tedious. So, I needed a simple app that would track this.<p>I am not usually a fan of &quot;vibe coded&quot; apps, but this was an ideal candidate for it, since it&#x27;s not production code. Most LLMs solve the problem by creating a single HTML file with forms that save data to localStorage. This was perfect for me - no hosting, no DB, no backend. Just 15 mins of prompting.<p>One day I was outside, just with my phone, and of course I couldn&#x27;t use the app. I thought &quot;how hard can it be to synchronize localStorage data across devices?&quot;. Turns out, it&#x27;s not that hard, if you are ready to build a whole platform around it.<p><a href="https:&#x2F;&#x2F;htmlsync.io" rel="nofollow">https:&#x2F;&#x2F;htmlsync.io</a> does just that. You upload your HTML app that works with localStorage and get a subdomain for it. The tool automatically synchronizes your changes across devices. You can create private and public apps, can decide which keys to synchronize by using the &quot;no_sync_&quot; prefix. The &quot;public-hidden&quot; CSS class can be used to hide UI elements in public view. You also get a subdomain for your profile where all your apps are listed for easy access.<p>I hope you find this as useful as I did.<p>I&#x27;d also appreciate your feedback if you end up using it.

[Database] Show HN: OrioleDB Beta12 Features and Benchmarks Hey HN, I&#x27;m the creator of OrioleDB, an extension for PostgreSQL that serves as a drop-in replacement for the default Heap storage engine. It is designed to address scalability bottlenecks in PostgreSQL&#x27;s buffer manager and reduce the WAL, enabling better utilization of modern multi-core CPUs and high‑performance storage systems.<p>We are getting closer to GA. This release includes:<p>- An index bridge to support all indexes that Heap supports<p>- Support for rewinding recent changes in the database.<p>- Tablespaces support<p>- Fillfactor support<p>- An orioledb_tree_stat() function for space utilization statistics<p>- Support for tables with more than 32 columns.<p>We also show several performance improvements using the TPC-C benchmarks. Overall, OrioleDB is much faster than Heap, also outperforming other Postgres providers.<p>We would love more people testing OrioleDB. The fastest way to do that is to use the docker image provided:<p><pre><code> docker run -d --name orioledb -p 5432:5432 orioledb&#x2F;orioledb </code></pre> Read the full release here:<p><a href="https:&#x2F;&#x2F;www.orioledb.com&#x2F;blog&#x2F;orioledb-beta12-benchmarks" rel="nofollow">https:&#x2F;&#x2F;www.orioledb.com&#x2F;blog&#x2F;orioledb-beta12-benchmarks</a>
