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: 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!

Show HN: Tabular – Email design tool that generates bulletproof email HTML
Hi HN,<p>I’ve developed <a href="http://tabular.email" rel="nofollow">http://tabular.email</a> (Tabular), a new email design tool that generates hybrid mobile-first email HTML. Think of emails for your app, such as user verification or welcome, newsletters, or marketing emails.<p>My goal was to make designing emails as quick and intuitive as possible. To make a tool where everything is done visually (adjusting margins, paddings, gaps, dimensions etc.), without the user having to worry about writing email HTML code.<p>Cool thing is that you get full control over how your email looks on mobile devices. When designing, you can switch to mobile mode, and any styling changes that you make will overwrite how it looks on desktop.<p>Tabular’s algorithm generates responsive HTML code that renders on all major email inboxes and devices, including older desktop Outlooks (e.g. Outlook 2010, 2013 etc.). At the moment, I’ve implemented 8 integrations so you can connect your email service provider (e.g. Sendgrid, Mailgun) to use it there directly, or download the HTML and upload it manually.<p>You can create any design structures using the row and column blocks. Nest the blocks however you like without constraints on how you use them to create structures. Combine the blocks to create complex designs or data tables for example.<p>I’d love to hear your feedback.

Show HN: Crul – Query Any Webpage or API
Hi HN, we’re Carl and Nic, the creators of crul (<a href="https://www.crul.com" rel="nofollow">https://www.crul.com</a>), and we’ve been hard at work for the last year and a half building our dream of turning the web into a dataset. In a nutshell crul is a tool for querying and building web and api data feeds from anywhere to anywhere.<p>With crul you can crawl and transform web pages into csv tables, explore and dynamically query APIs, filter and organize data, and push data sets to third party data lakes and analytics tools. Here’s a demo video, we’ve been told Nic sounds like John Mayer (lol) (<a href="https://www.crul.com/demo-video" rel="nofollow">https://www.crul.com/demo-video</a>)<p>We’ve personally struggled wrangling data from the web using puppeteer/playwright/selenium, jq or cobbling together python scripts, client libraries, and schedulers to consume APIs. The reality is that shit is hard, doesn’t scale (classic blocking for-loop or async saturation), and comes with thorny maintenance/security issues. The tools we love to hate.<p>Crul’s value prop is simple: Query any Webpage or API for free.<p>At its core, crul is based on the foundational linked nature of Web/API content. It consists of a purpose built map/expand/reduce engine for hierarchical Web/API content (kind of like postman but with a membership to Gold's Gym) with a familiar parser expression grammar that naturally gets the job done (and layered caching to make it quick to fix when it doesn’t on the first try). There’s a boatload of other features like domain policies, scheduler, checkpoints, templates, REST API, Web UI, vault, OAuth for third parties and 20+ stores to send your data to.<p>Our goal is to open source crul as time and resources permit. At the end of the day it’s just the two of us trying to figure things out as we go! We’re just getting started.<p>Crul is one bad mother#^@%*& and the web is finally yours!<p>Download crul for free as a Mac OS desktop application or as a Docker image (<a href="https://www.crul.com" rel="nofollow">https://www.crul.com</a>) and let us know if you love it or hate it.
