Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News
Hello HN!<p>TLDR;<p>- Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric.<p>- We propose that this metric could be used to improve the Hacker News ranking score.<p>- In-depth explanation: <a href="https://github.com/social-protocols/news#readme">https://github.com/social-protocols/news#readme</a><p>The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on...<p><pre><code> →
↗ ↘
Higher Rank More Upvotes
↖ ↙
←
</code></pre>
As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best.<p>Our proposed solution is to use upvoteRate instead of upvotes in the ranking formula. upvoteRate is an estimate of how much more or less likely users are to upvote a story compared to the average story, taking account how much attention the story as received, based on a history of the ranks and times at which it has been shown. You can read about how we calculate this metric in more detail here: <a href="https://github.com/social-protocols/news#readme">https://github.com/social-protocols/news#readme</a><p>About 1.5 years ago, we published an article with this basic idea of counteracting the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community (<a href="https://news.ycombinator.com/item?id=28391659" rel="nofollow">https://news.ycombinator.com/item?id=28391659</a>). Quality News has been created based largely on this feedback.<p>Currently, Quality News shows the upvoteRate metric for live Hacker News data, as well as charts of the rank and upvote history of each story. We have not yet implemented an alternative ranking algorithm, because we don't have access to data on flags and moderator actions, which are a major component of the HN ranking score.<p>We'd love to see the Hacker News team experiment with the new formula, perhaps on an alternative front page. This will allow the community to evaluate whether the new ranking formula is an improvement over the current one.<p>We look forward discussing our approach with you!<p>Links:<p>Site: <a href="https://news.social-protocols.org/" rel="nofollow">https://news.social-protocols.org/</a><p>Readme: <a href="https://github.com/social-protocols/news#readme">https://github.com/social-protocols/news#readme</a><p>Previous Blog Post: <a href="https://felx.me/2021/08/29/improving-the-hacker-news-ranking-algorithm.html" rel="nofollow">https://felx.me/2021/08/29/improving-the-hacker-news-ranking...</a><p>Previous Discussion: <a href="https://news.ycombinator.com/item?id=28391659" rel="nofollow">https://news.ycombinator.com/item?id=28391659</a>

Show HN: ChatGPT Bot Trained on Reddit Data
I'm heavily relying on Reddit for my online research, but there are many repetitive questions and recommendations on subreddits, so I trained a GPT bot on over 100k r/BuyItForLife comments and posts to embody the collective knowledge of this Reddit community (and soon many other subreddits).<p>Some posts I answered with the bot:<p>- Request Post: Dishwashers. What’s currently the best dishwasher for home use?<p>- Bot Answer: <a href="https://www.looria.com/bot?q=what's+currently+the+best+dishwasher+for+home+use" rel="nofollow">https://www.looria.com/bot?q=what's+currently+the+best+dis...</a><p>- Request Post : Recommendations for hiking shoes?<p>- Bot Answer: <a href="https://www.looria.com/bot?q=Recommendations+for+hiking+shoes" rel="nofollow">https://www.looria.com/bot?q=Recommendations+for+hiking+shoe...</a><p>------------<p>It's far from perfect and comes with limitations:<p>- Outdated information: I'll try to improve this by factoring in recency and some additional product information like prices, specs, etc, that I'm collecting. I also want to add more statistical significance to the results, e.g. by feeding in the amount of product recommendations over time.<p>- Hallucination: As always with these bots, they sometimes make things up. More training data should help here.<p>- Performance: Generating the answers is pretty slow and I'll look into improving this.<p>Take it with a grain of salt and look at it as a fun experiment :) Would love to hear your feedback!

Show HN: Touca – a better alternative to snapshot testing
Hi everyone,<p>Almost 2 years ago, I left my full-time job at Canon to build tooling and infrastructure to help developers write high-level tests for complex software workflows that are not easy to unit test. I wanted to take ideas from visual regression testing, snapshot testing, and property-based testing and build a general-purpose regression testing system that developers can use to find the unintended side-effects of their day-to-day code changes during the development stage.<p>After two years of working ~70 hours per week and going through multiple iterations, we finally have a fully open-source (Apache-2.0) product that finally makes me and other members of our community happy: <a href="https://github.com/trytouca/trytouca">https://github.com/trytouca/trytouca</a><p>This week we released v2.0, a milestone version that is useful to small and large teams alike. This version comes with:<p>- An easy to self-host server that stores test results for new versions of your software workflows, automatically compares them against a previous baseline version, and reports any differences in behavior or performance.<p>- A CLI that enables snapshot testing without using snapshot files. It lets you capture the actual output of your software and remotely compare it against a previous version without having to write code or to locally store the previous output.<p>- 4 SDKs in Python, C++, Java, JavaScript that let you write high-level tests to capture values of variables and runtime of functions for different test cases and submit them to the Touca server.<p>- Test runner and GitHub action plugins that help you continuously run your tests as part of the CI and find breaking changes before merging PRs.<p>I would really appreciate your honest feedback, positive or negative, about Touca. Would love to learn if you find this useful and look forward to hearing your thoughts and answering any questions.
Show HN: Usage 2.0 – Cut AWS Spend by 57% in 5 Minutes
Hey HN: Kaveh here, the founder of https://www.usage.ai/<p>We launched on Hacker News for the first time early last year, and we've made a lot of progress since then. We've saved tens of millions of dollars for companies, and we are even more excited to announce the launch of a new product: insured reservations for RDS! We worked closely with AWS on this feature and are excited to finally make it generally available.<p>We help companies drive down AWS EC2 & RDS spend. Why? Because the way it's done now is a pain. DevOps and Software Engineers end up spending time managing costs and reservations rather than focusing on business problems.<p>In the early days, we saw horror stories of customers with millions of dollars in monthly on-demand spend simply because their finance team didn't want them committing to AWS. Worst yet, we've seen AWS users who ended up overspending by hundreds of thousands of dollars a month because they overcommitted their Savings Plan commitment.<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, and RDS spend by ~30%.<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.<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: ChatGPT-powered dystopia simulator
OP here. This comment contains SPOILERS so try the dystopia simulator first before reading further!<p>I built "WeChatGPT+" in December on top of GPT-3. It was pretty surreal when OpenAI released an actual product named "ChatGPT Plus" a few months after that. Then the Microsoft partnership was announced, Bing AI was released, and marketing materials were leaked indicating that Bing AI would start including advertisements within the chat responses. Reality imitates fiction, I guess.<p>Today - literally a few hours ago - OpenAI announced public ChatGPT API with 10% the cost of GPT-3. I immediately migrated. Took about an hour to re-tune the prompt for a different model. I wouldn't have been able to afford serving this over the GPT-3 API because it costs so much (I'd kept the server disabled for more than a month). Should be much more affordable now. Also some of the responses seem wittier and funnier.<p>Prompt generation and other source code available here: <a href="https://github.com/baobabKoodaa/future/blob/master/server.js#L58-L99">https://github.com/baobabKoodaa/future/blob/master/server.js...</a><p>Let me know how you feel about this! :)

Show HN: ChatGPT-powered dystopia simulator
OP here. This comment contains SPOILERS so try the dystopia simulator first before reading further!<p>I built "WeChatGPT+" in December on top of GPT-3. It was pretty surreal when OpenAI released an actual product named "ChatGPT Plus" a few months after that. Then the Microsoft partnership was announced, Bing AI was released, and marketing materials were leaked indicating that Bing AI would start including advertisements within the chat responses. Reality imitates fiction, I guess.<p>Today - literally a few hours ago - OpenAI announced public ChatGPT API with 10% the cost of GPT-3. I immediately migrated.

Show HN: Dak – a Lisp-like language that transpiles to JavaScript
Hi HN, author here. Happy to answer any questions.<p>I had an itch to make a lisp like language that was a thin layer on top JavaScript. Something that could leverage the thriving ecosystem that exists around JavaScript. It's brittle, hot off the oven.<p>Besides being a fan of parenthesis, I think macros fill in a gap that the JavaScript ecosystem today fills in with one-off compilers, bundler plugins and such. Macros can't do everything, but for example I think they have the potential to enable things like JSX, Solid and Svelte style libraries.<p>Take the tour to get a feel for what it can do and play with the live code in your browser!
