Show HN: Open Prompts – dataset of 10M Stable Diffusion generations
Open Prompts is the dataset used to build krea.ai. The data comes from the Stability AI Discord and includes around 10M images from 2M prompts. You can use it for creating semantic search engines of prompts, training LLMs, fine-tuning image-to-text models like BLIP, or extracting insights from the data—like the most common combinations of modifiers.

Show HN: TaskTXT, plain text task-timing notepad
I built TaskTXT.com based on my experience timing my tasks. I found that committing to a task before I start helps with my focus, and guessing how long it will take, then timing it prevents me from wanting to give in to distractions because I'm "on the clock".<p>Video Overview: <a href="https://www.youtube.com/watch?v=HOYO0c_D6w0" rel="nofollow">https://www.youtube.com/watch?v=HOYO0c_D6w0</a><p>There's also a Mac app which you can download here: <a href="https://dl.todesktop.com/22080519n9z1jew/mac" rel="nofollow">https://dl.todesktop.com/22080519n9z1jew/mac</a><p>Video overview of the Mac app: <a href="https://www.youtube.com/watch?v=qMs-V5v5gZY" rel="nofollow">https://www.youtube.com/watch?v=qMs-V5v5gZY</a><p>But I didn't want the tool to be distracting, so its based on plain text. That means the UI is very familiar and you can use it for generic notes in any structure you like. When you work in TaskTXT you are working directly on its data format, I made a video about this concept here: <a href="https://www.youtube.com/watch?v=kZdBgVZn5NI" rel="nofollow">https://www.youtube.com/watch?v=kZdBgVZn5NI</a><p>I think this tool is uniquely suited for programmers, so I'd be interested to hear any feedback about the product, or its viability as a business.
Show HN: Figr.app – a multi-user, notepad style calculator (desktop app)
Hi all, just posting an update to my previous Show HN, where I announced a side-project I worked on which was a (web version) of a multi-user, notepad style calculator:<p><a href="https://news.ycombinator.com/item?id=31817997" rel="nofollow">https://news.ycombinator.com/item?id=31817997</a><p>After a couple of user requests (and having a good think about it) I decided to migrate the web UI to create a Mac and Windows desktop app. After using it a little bit, I feel this is a much better experience than the webapp, and reduces a lot of the friction if I wanted to run a few small calculations.<p>You can find the download links below:<p><a href="https://www.figr.app/download" rel="nofollow">https://www.figr.app/download</a><p>For context, Figr was a side project I worked on to get back into coding after being in management for the last few years. It's kind of a cross between popular notepad style calculators (like Soulver, Numi, etc), but also has multi-user editing (like Google Docs). I've got some example templates below which hopefully show what it can do, and hopefully is relevant to the community:<p>- <a href="https://www.figr.app/s/RUNWAY" rel="nofollow">https://www.figr.app/s/RUNWAY</a> - An example to work out your burn rate / runway<p>- <a href="https://www.figr.app/s/LTVCAC" rel="nofollow">https://www.figr.app/s/LTVCAC</a> - An LTV/CAC calculator<p>- <a href="https://www.figr.app/s/CONTRACTOR" rel="nofollow">https://www.figr.app/s/CONTRACTOR</a> - Hourly rate calculator for contractors<p>Opened to feedback, or technical questions if others are in the process of moving, or thinking about moving their webapps to desktop apps, as it's been quite a journey!<p>Thanks!
Show HN: Distributed JMAP and IMAP Servers in Rust
I am happy to announce Stalwart JMAP [1], an open-source JSON Meta Application Protocol server that aims to be scalable, robust and secure. Some of its key features are:<p>- JMAP Core, JMAP Mail and JMAP over WebSocket full compliance.
- IMAP4 rev2/1 support via Stalwart IMAP, an imap-to-jmap proxy [2].
- Scalable and fault tolerant: consensus over Raft, node autodiscovery over gossip and read-only replicas.
- RocksDB backend with full-text search support in 17 languages.
- OAuth 2.0 authorization code and device authorization flows.
- Domain Keys Identified Mail (DKIM) message signing.
- Written in Rust.
- No third-party software required to run or scale.<p>The next item on the roadmap is to release an SMTP server in Rust with the goal of making self-hosting an e-mail server much simpler.<p>Any comments or suggestions are more than welcome!<p>[1]: <a href="https://github.com/stalwartlabs/jmap-server" rel="nofollow">https://github.com/stalwartlabs/jmap-server</a>

Show HN: Low-cost backup to S3 Glacier Deep Archive
Hi,<p>most people (hopefully) have local backups. However, when that backup fails, it is good to have a backup stored somewhere off-site. In the old days you would ship physical drives/tapes, which is cumbersome, costly, and slow. With fast upload speeds, it is now possible to upload your data to the cloud. I have found S3 Glacier Deep Archive to be a great solution for this:<p>- It is very cheap ($1/TB/month for US region)
- Very reliable (99.999999999% data durability, data spread over 3 Availability Zones)<p>However, usability out of the box is not that great, I'm not aware of any automated backup solution for Deep Archive. This free project provides that.<p>Currently, ZFS is required, but that might change. Please try it out and provide feedback!

Show HN: StackAid – Fund all your open-source dependencies
We strongly believe working on open source software should be a viable source of income for many more developers. Unfortunately, the following barriers limit the extent of open source funding:<p>- Only a small fraction of open source projects are funded, and most money goes to a few notable projects.<p>- Each project has to market is self to get significant funding.<p>- Large corporate donations provide the bulk of the funding, making it unreliable and unattainable for many.<p>- Finding and supporting each of your dependencies is a cumbersome task. Which ones, how much, and on which platforms?<p>So we built StackAid, a service that automatically discovers and funds your direct and indirect (second order) open source dependencies with a monthly subscription. StackAid is early and has a unique allocation model, so we're working with supporters and open source projects to validate the experience further. We're matching subscriptions up to $100/month during the beta.

Show HN: Mini Metroidvania in 13KB of JavaScript
As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript.<p>The source is available here: <a href="https://github.com/arikwex/infernal-sigil" rel="nofollow">https://github.com/arikwex/infernal-sigil</a><p>NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github.<p>Useful hacks:
- Using Roadroller (<a href="https://github.com/lifthrasiir/roadroller" rel="nofollow">https://github.com/lifthrasiir/roadroller</a>) for compression
- Compressing the map data as grayscale PNG paired with some code generation.
- Using procedural animation for all characters.
- Replacing string enum with numeric enums for compression.
- Built a small game engine for object lifecycle and rendering.
- Single function to generate unique procedural songs for different regions.
