Show HN: Nine Letter Word – Daily Puzzle
I've been playing Wordle and remembered this puzzle game I used to play with my grandfather. It's inspired by the block puzzles in many newspapers but made to be shorter: just guess the nine letter word.<p>So I made a quick thing to play with my family like we used to. I thought you guys might enjoy it.

Show HN: Lava lamp simulated by neural net in infinite loop
duralava is a neural network which can simulate a lava lamp in an infinite loop.<p>It uses a recurrent GAN that learns the physical behavior of the lava lamp.<p>A noteworthy aspect is that can generate an arbitrarily long video of a (virtual) lava lamp, without diverging even after thousands of frames.

Show HN: A collaborative pixel drawing game for when you're bored
Hello HN. This is a project me and some friends built at university in 2017. It was originally built in a rush, but we've added a few improvements over the years. It's a fun game to host at a demoparty and project on a big screen - We did that at Instanssi many times. The implementation is still rough, and suffers from the fast pace of the modern web - The frontend is likely very outdated, and the backend is built with Vapor 2 and Swift 3.1, both no longer supported. You <i>can</i> host this yourself, but it might be a bit of a pain to set up. The WebSocket protocol is fairly trivial to work out and write a bot for to ruin the whole canvas, but I trust that the HN crowd can come up with clever things to draw with a script, should they choose to do so. The server is recording draw events into a log, and I will be posting a timelapse here in the comments after some time. Have fun!
Show HN: I've built my own simple website analytics
Show HN: Download Twitter data without API keys
In April last year I started thinking about using Twitter in a smarter way. I wanted to do analytics on my tweets and find out more about people following me on Twitter. What kinds of things do people who follow me like and retweet? I decided to dig into the data and find out.<p>When I went to try and download Twitter data in raw form I found I quickly got bogged down writing API wrangling code and fiddling with API keys. I just wanted to crunch some data but here I was wrangling Twitter's API. This was such a frustrating experience it suddenly looked like an opportunity to me. Was there room for a product here? A product which does one simple thing: help people extract Twitter data painlessly without writing any code.<p>I did some research and discovered some tools that purported to do this, but none of them worked well for my use-case and all were badly designed and/or expensive. I decided to take a shot at it.<p>I worked on this as a side project in a "calm company" fashion. Each week for 26 weeks I would put aside one day to chip away at the features. I tried not to think about how the issue tracker was filling up more and more. Several times I pared back the feature set to try to really focus on the core use-case.<p>When my first user reached out and engaged I knew I might be onto something. I kept posting progress on Twitter and a few more people started to use it each week. Some of them came back, hinting at possible user retention. I hired a writer to write some articles to help with SEO and I kept working towards and MVP that I could use to test the market.<p>Finally the day arrived where all of the critical issues in my issue tracker were closed. That meant it was launch day. That was yesterday. So here I am releasing this on Hacker News to you, dear reader.<p>God speed little micro-SaaS, may the winds of fortune be at your back.

Show HN: Angularis – like Tetris, but based on triangles
Angularis is a game similar to Tetris, but based on triangles instead of squares. Which is why it also has diagonal movements. I had this idea about a month ago and built the game in my spare time.<p>I think it is a bit more difficult compared to Tetris. You kind of have to get used to "think diagonally".<p>Maybe it can be a nice little challenge for you.<p>I'd be happy to receive some feedback. Thanks!

Show HN: I built a service to help companies reduce AWS spend by 50%
Hey HN: Kaveh here, the founder of https://www.usage.ai/<p>We help companies drive down AWS EC2 spend. Why? Because the way it's done now is a pain. DevOps and Software Engineers end up spending time managing costs rather than focusing on business problems.<p>Previous to founding Usage, I worked on high-performance computing research at JP Morgan Chase and as a software engineer at a number of smaller startups.<p>Here's how it works: We are typically brought in by a DevOps manager to cut AWS EC2 costs. The app is entirely self-service and the savings are generated automatically, typically we do this live on a call. On average, we reduce AWS EC2 spend by 50% for 5 minutes of work.<p>To reduce by 50%+, we don't touch the instances, require any code change, or change the performance of your instances. We buy Reserved Instances on your behalf (a billing layer change only) and bundle them with guaranteed buyback. So you get the steep 57% savings of 3-year no-upfront RIs with none of the commitment (you can sell them back to us anytime after 30 days).<p>We make money off of a 20% Savings Fee. Happy to chat directly kaveh@usage.ai<p>Have you experienced any issues with managing your company or organization's AWS expenses? We'd love to hear your feedback and ideas!

Show HN: Find alternatives to almost any popular GitHub repo
Several months ago, I built a "stealth" feature that I could use. It hasn't been advertised, and I've been the only user. As I find it useful for myself, I believe others (software developers) may like it too. So, this is the first public post about it, and if it gets any positive feedback, I may put some time into promoting it more.<p>In essence, given that you've opened a GitHub repo (there are ~225k of the more popular ones indexed as of now), you can replace "github" with "libhunt" within the URL, and you will find the top alternatives and related projects.<p>For example, here are three popular repos:<p>- <a href="https://github.com/rails/rails" rel="nofollow">https://github.com/rails/rails</a><p>- <a href="https://github.com/vercel/next.js" rel="nofollow">https://github.com/vercel/next.js</a><p>- <a href="https://github.com/kovidgoyal/calibre" rel="nofollow">https://github.com/kovidgoyal/calibre</a><p>To test it out, open any of the examples above and replace "github" with "libhunt" within the browser URL. You can also try with any other repository as long as it's a bit popular.<p>I'd be more than happy to answer any questions and receive some feedback. Thanks!
Show HN: Edit videos faster by automatically removing silences
Our team is filled with technologists and creators, and when we record and edit videos, 80% of the time is spent chopping up the video, removing silences, and picking the right takes. So we decided to build a tool that did that for you — or at least get you there most of the way!<p>Our initial implementation is somewhat naïve and uses a user configurable silence threshold that just reads in volume levels. In the future, we’d like to use a frequency-based approach that focuses on the human voice. We’re also open to ideas, so let us know if you have any!
