Show HN: Sort Any Awesome List by GitHub Stars https://ift.tt/N5PwICY

Show HN: Sort Any Awesome List by GitHub Stars As a CS undergrad, I self-taught many topics not covered by the school. Typically awesome list is where I started with. I spent my second half in college researching computer vision and machine learning. CVPR accepts over 2000 papers every year, not to mention arXiv. The awesome lists curated by the community usually serve as checklists when I was doing literature surveys. But since the number of the list items was overwhelming, I had to prioritize which papers to read first. Many of them had been uploaded to arXiv in the last few months, so I had no clue how many citations they would get. When learning web development, I also had difficulty finding the best package for the tasks like data validation and client-side routing. To make a decision, I had to browse through GitHub repositories or read the documentation. I wish I could have my awesome lists sorted, desirably by popularity. This led to the creation of my project: a web app that rearranges any awesome list with hints from GitHub stars. It may not work well when the list items do not contain links to GitHub repositories or pages, but it truly shines when most of them do. I hope this could help anyone else. P.S. I'm aware of a similar project ( https://ift.tt/OgnPwI3 ), a CLI application with more features. For example, it checks if any GitHub repository link exists on the linked website. https://ift.tt/W8UkmY5 March 3, 2023 at 12:21AM

Show HN: Mathesar – open-source collaborative UI for Postgres databases https://ift.tt/1idgwTm

Show HN: Mathesar – open-source collaborative UI for Postgres databases Hi HN! We just released the public alpha version of Mathesar ( https://mathesar.org/ , code: https://ift.tt/Fmelkdb ). Mathesar is an open source tool that provides a spreadsheet-like interface to a PostgreSQL database. I was originally inspired by wanting to build something like Dabble DB. I was in awe of their user experience for working with relational data. There’s plenty of “relational spreadsheet” software out there, but I haven’t been able to find anything with a comparable UX since Twitter shut Dabble DB down. We're a non-profit project. The core team is based out of a US 501(c)(3). Features: * Built on Postgres : Connect to an existing Postgres database or set one up from scratch. * Utilizes Postgres Features : Mathesar’s UI uses Postgres features. e.g. "Links" in the UI are foreign keys in the database. * Set up Data Models : Easily create and update Postgres schemas and tables. * Data Entry : Use our spreadsheet-like interface to view, create, update, and delete table records. * Data Explorer : Use our Data Explorer to build queries without knowing anything about SQL or joins. * Schema Migrations : Transfer columns between tables in two clicks in the UI. * Custom Data Types :: Custom data types for emails and URLs (more coming soon), validated at the database level.

Show HN: Try out the new ChatGPT API on Promptly https://ift.tt/gIGoOxu

Show HN: Try out the new ChatGPT API on Promptly Hey HN Community, We're excited to announce the integration of the newly launched ChatGPT API into Promptly - a platform designed to make prompt management and sharing a breeze for developers. With Promptly, you can easily test out different prompts and model parameters for various providers, and quickly share prompt snippets together with parameters and generated output. It's like CodePen or JSFiddle, but for prompts! In addition to that, Promptly also allows you to create high-level endpoints on top of provider APIs (such as Open AI, DreamStudio, and more) with templated and versioned prompts. And with built-in caching for endpoints, you can save on Open AI costs and improve latency. Today, we're thrilled to add the ChatGPT API to our platform. So head on over to Promptly and try it out for yourself! It's easy, intuitive, and completely free to use. Check it out at https://ift.tt/Gi9oKDv We can't wait to see what amazing prompts and endpoints you'll create with Promptly. Happy prompting! https://ift.tt/DnTlFaf March 2, 2023 at 02:01AM

Show HN: Supaglue – open-source unified API https://ift.tt/2eonBPV

Show HN: Supaglue – open-source unified API Last month, we open-sourced Supaglue (https://ift.tt/I8FpefY) as a developer toolkit for building customer-facing Salesforce integrations. Since then, we've been iterating on our approach with users and are re-launching Supaglue as an open source unified API, starting with CRMs. With our re-launched public alpha you can: - Interact with HubSpot and Salesforce through a unified REST API - Sync data from HubSpot and Salesforce into a local Postgres cache and make reads against a normalized CRM schema - Make writes (POST and PATCH) to HubSpot and Salesforce using the unified API - Open source MIT license so anyone can self-host for free Today we support reads, creates, and updates for Accounts, Contacts, Leads, and Opportunities for HubSpot and Salesforce. In the coming weeks, we plan to add more connectors and features like configuring sync frequencies, webhooks for notifications, sync rate limiting/throttling. We'd love to hear your thoughts and any feature requests! Give it a try and let us know what you think! GitHub: https://ift.tt/I8FpefY Website: https://supaglue.com March 1, 2023 at 10:37PM

Show HN: Rapid Kubernetes Controller Development with Tilt and Silly Drawings https://ift.tt/AMrXOPY

Show HN: Rapid Kubernetes Controller Development with Tilt and Silly Drawings Like the says. I'm describing how to use Tilt to speed up the dev cycle of testing and coding Kubernetes controllers. Tilt uses a built in local registry to push images into and can use hot swapping to kickly deploy processes in containers. It's pretty neat. :) The Tiltfile can be a bit daunting but I'm trying to break it down as much as possible. :) I hope this helps! Good luck! https://ift.tt/ykzv2rQ March 1, 2023 at 05:38PM

Show HN: Our Favorite Websites Are Contributing to Climate Change https://ift.tt/pceniHL

Show HN: Our Favorite Websites Are Contributing to Climate Change If the internet were a country, it'd be the 7th most polluting. In the past 10 years alone, websites have grown 320% heavier. This website presents an analysis of the hidden cost of the internet's top 250 websites, comparing their carbon footprint & their yearly environmental impact. Our analysis shows that 40% of these websites generate significantly more than the global average of 0.5g CO2 per page load — some up to a whopping 16g. Compounded by millions or billions of visitors, they unnecessarily generate about 234,342,373kg (515M pounds) of CO2 every single year. This is the same as a gas car driving around the Earth 23 million times. We'd need around 4 billion trees growing for 10 years to absorb this amount. There are plenty of ways to reduce a website's emissions. For example, if all the analyzed websites were using a green host, the overall emissions would be 76.15% lower. That's a HUGE reduction with relatively little effort. However, most companies choose profit over the planet. https://ift.tt/6mpYyP7 March 1, 2023 at 09:36PM

Show HN: Collect and search robotics data with SensorSurf https://ift.tt/x45DghB

Show HN: Collect and search robotics data with SensorSurf We've been building SensorSurf and are thrilled to share our beta with the robotics community: https://ift.tt/BnoZNrl . SensorSurf is an open source platform that makes it easy for robotics engineers to collect and search data from their fleet. You can define triggers for when to record data (e.g. emergency stop) and capture the moments leading up to the event with rolling buffers. We integrate directly with ROS. Drop our agent into your system, and start collecting data! ================= What prompted me to found this company: > I was a perception engineer working on autonomous boats. > I needed tons of imagery to build computer vision datasets. > It was impossible to offload all this data over satellite. > I interviewed robotics companies, and learned this was a common problem. ================= Our beta enables you to: 1. Trigger recording on arbitrary ROS topic data. 2. Capture the data leading up to the trigger (rolling buffer). 3. Offload over a poor connection (set max upload rate). 4. Search imagery with natural language. ================= Open source announcement: https://ift.tt/LQEIRJv https://ift.tt/thHPK8d March 1, 2023 at 12:32AM
